Description
Technical field
When existing moving body all the time and moving in water, speed often doubles, its required saying by octuple merit.In order to improve the running velocity in water, people have carried out many effort: as moving body part in water is made sharp longerly, and add airflow design, add high-power (displacement) simultaneously and improve speed to overcome resistance; There is the resistance overcoming to transfer to the hydrofoil boat of hydrofoil; Depart from the air cushion vehicle of the water surface with air cushion; Reduce the catamaran of part cross-sectional area in water; Utilize inclined-plane to hold out the speedboat of the water surface and strut the submarine-based missile, the submarine etc. that substitute front resistance with air pocket.Although on running velocity, some breaks through air pocket technology, power consumption is too large and be subject to the restrictions such as water depth pressure, and its stroke is not grown.They do not obtain substantive breakthroughs, can not be popularized yet.The Zhe Shiyige world today is making great efforts to study problem demanding prompt solution
Background technology
If got rid of operation front resistance, the raising that its running velocity will leading to a leap property, its economic outlook, particularly, with militarily that is unmatched, has special important meaning.The present invention solves side by side except the resistance problem before moving body in water.This is a kind of actuating unit of operation under water of novel concept.China is subject to a lot of infringements and threatens in the problem of island, territorial waters at present.If first this technology is used in national defence, just can make unprecedented high-speed torpedo, submarine, battleship.This is the importance that war is won victory, and has more special especially realistic meaning.

Detailed description of the invention:
One. groundwork and the technical scheme of the actuating unit of afflux exclusion operation under water
Groundwork scheme about afflux cover exclusion operation actuating unit is: be positioned on the afflux cover arranging in the afflux exclusion operation actuating unit of the lower apron on moving body, its outward appearance is straight sleeve shape, see that along on service direction outside face is straight, cross-sectional plane outside geomery is identical everywhere for it, and is totally greater than and similar in appearance to moving body maximum cross section part.Modern quick moving body in water is all generally strip, surface is all smooth straight, in the past tip is to the cross-section of maximum cross section in the expansion stage, it is the main portion that produces running resistance, but continue one section of cross-sectional plane constant (being also straight-tube shape) backward from maximum cross section, just likely occur backward that again cross-sectional area dwindles, such straight tube surface all only may produce small friction drag in moving body, if add the top layer of capable of reducing friction resistance, even negligible in theory.As the straight flat pipe direct-axis of the thin skin with desirable in fast direct water, imperceptible resistance and with desirable smooth straight thin plate along plane in water fast swing, imperceptible resistance is the same.The outside of same afflux cover is also straight along service direction, and cross-sectional area is identical everywhere, does not produce resistance.Such overall appearance can ensure that moving body no longer produces new resistance getting rid of in advancing after resistance, can guarantee that running velocity further improves.
Afflux cover advances the mouth of a river before the head of moving body, the water stream channel that has one section of cross-sectional area to dwindle in the mouth of a river cross-sectional plane inwards that advances being overlapped by afflux, simultaneously afflux cover advances and also contains one section in the cross-sectional area inwards of the mouth of a river and accelerate because draining produces current, and water stream channel cross-sectional area dwindles and the cross-sectional area of the moving body abdicating, strengthen.The cross-sectional plane of afflux cover is greater than and is similar to moving body maximum cross section, and its mouth of a river of advancing is in moving body foremost, and this just limits and determined the range of resistance of need eliminatings in the front that is greater than moving body the maximum cross-section area and operation.Help wave making theory all to think that the water before the front maximum cross section of moving body is exactly resistance in displacement operation theory and present generation.Modern rear-guard power moving body is all to arrange front by extruding in the continuous process expanding of the cross-sectional area before moving body maximum cross section produce the water of resistance and produce wave, and current collecting tier dynamic resistance force mechanisms is initiatively to suck and get rid of front to produce the water of resistance, and can not produce the spray.
On water stream channel, be equipped with the actuating unit of draining backward, current water outlet after afflux cover of crossing after actuating unit discharges to produce operation power.In the time of the dynamic structure work done of draining backward, inevitable waters before dynamic structure produces a negative pressure, negative pressure before this power passes to the overall negative pressure region of the cross-sectional plane scope forming when afflux cover advances mouth of a river place just, namely this produce water in range of resistance by the comprehensive suction of entirety in water stream channel, the resistance of having got rid of front again after afflux cover water outlet discharge and produce operation power, namely advance waterside that mouth of a river entirety sucks front of afflux cover is got rid of resistance limit and is moved ahead; Rear water outlet produces positive pressure power limit water discharge limit and moves ahead, and interlock is advanced jointly to moving body.Be not subject to the restrictions such as the depth of water, also can say water darker under large pressure exclusion better.By the theory of displacement, the thing in operation front is transferred to exactly to the rear of operation as bit bore, displace the space of oneself advancing.And being moved on to, thing above also needs after one's death a space, Here it is water stream channel, namely the cross-sectional area of afflux cover is moving body the maximum cross-section area and water stream channel cross-sectional area sum, the current of namely discharging from rear water outlet because of the ratio of the shared total cross-sectional area of water outlet less, its current are more long-range more greatly, otherwise less.
The cross-sectional area of water stream channel must not be less than the work done area of dynamic structure, and after mistake dynamic structure, the interior cross-sectional area of a segment distance of water outlet steadily expands cover planted agent backward again, efficiency when this just can ensure power work done.Comparatively speaking, water outlet cross-sectional area is larger, forms water wave less.
Because the resistance water in the front being excluded is from operational system interior shifting to rear, be not subject to the interference of outside water, the guarantee that adds the straight-tube shape profile of afflux cover and part moving body does not produce drag effect, namely the moving body at this moment non-resistance that moves ahead can be looked displacement and determines running velocity theoretically, and because dynamic structure is in operational system inside, and afflux cover can stop again a part of noise, just can realize high-speed and high-efficiency operation, its advantage is not limited by liquid depth equipressure, again energy-conservation, the spray is little, noise is little.Compare with the moving body of general rear-guard power, rear-guard power is that extrusion drainage produces the power driving forwards backward, and driving forwards of the actuating unit of afflux exclusion operation is under water to get rid of operation front to hinder the amount of moving water, do not need rear-guard power to produce backward huge pressure.Same large displacement does not need propulsive effort large power like that backward.Although be all draining while moving ahead, it is much laborsaving that this mechanism wants, and also just can not need the merit of the speed octuple often doubling.
Primary Calculation method about running velocity is: total displacement ÷ afflux overlaps efficiency factor of total cross-sectional area *.
The explanation of the groundwork accompanying drawing (1-4) of the actuating unit of afflux exclusion operation under water, wherein accompanying drawing 1 is basic profile schematic diagram; Accompanying drawing 2 is shaft flow structure schematic diagram; Accompanying drawing 3 is mixed-flow structural representation.Accompanying drawing 4 stretches out the advance structural representation at the mouth of a river of afflux cover for tip before moving body.
1. structure: (note: this is that moving body cross-sectional plane is apart from circular, after afflux cover, water outlet is before moving body maximum cross section, power is single screw, be positioned at the principle schematic at tip place before moving body) perpendicular flow deflector 3. by certain regular distribution on a main body front surface 5., and support is fixed wtih afflux and overlaps 1., overlap on rear water outlet 1. and the main body perpendicular flow deflector between 5. and horizontal flow deflector is installed circlewise 4. at afflux, dynamic structure (screw propeller) is 2. positioned in the concentric axis that moving body approaches tip and is in afflux and overlaps in the circle advancing in the mouth of a river 1..
2. operation mechanism: under the effect of power spin blade sheet, the water that afflux is overlapped to the mouth of a river Inner Front End that 1. advances is continuously discharged to rear, perpendicular flow deflector below be 3. in main body 5. before on head surface, overlapping 1. inside face with afflux is connected, the front end of perpendicular flow deflector has along the radian of water flow bending, downstream stream accept screw propeller discharge with the current along blade oar helical propensity, reduce to greatest extent the degradation of energy producing because of annular flow, and following current bending guide, make it to flow to dead aft, reach the object that improves drainage efficiency, and play the effect that is connected and fixed afflux cover.Through the current of screw propeller effect, through main body surface 5., 3. perpendicular flow deflector overlaps inside face 1. with afflux is combined and forms band curved channel side by side, before the cross-sectional plane of moving body maximum, flows out.Require can try one's best and steadily flow out backward at the rear water outlet of afflux cover, generation antagonistic force promotes moving body and moves forward.Here 4. horizontal flow deflector plays layering discharge, is to make the water being discharged from more paste moving body surface backward to obtain maximum power effect by the guiding of self.(according to the horizontal flow deflector of actual conditions can)
About electromagnetic power level structure groundwork technical scheme: the surface of the supporting body (being called for short supporting body here) of the moving body in water or electromagnetic power structure is implanted into the pole-face that permanent magnet or electromagnet (the most handy superconductor) make to produce the magnetic pole (N, S) of magnetic line of force and is exposed at surface, and equal with moving body (or supporting body) surface, pass to galvanic electrode (+,-) be embedded in moving body (or supporting body) surface, and the pole-face of the electrode to water conduction is also equal with moving body (supporting body) surface, reveal magnetic pole electrode pole-face be strip, and growing up in the length of electrode of magnetic pole, Changshun service direction of electrode magnetic pole, electrode magnetic pole wide perpendicular to service direction, and electrode magnetic pole be that order is going up equidistant discharge perpendicular to service direction (water (flow) direction) continuously by an electrode (as+) magnetic pole (as N) electrode (-) magnetic pole (S), can touch the laterally inside and outside bend alignment of water surface along moving body (supporting body), also can continue transversely arranged, form the docking of this electromagnetism discharge, form inside and outside ring-type.It is certain each adjacent with its different electrode (-) that such continuous blow-down meeting forms wherein each electrode (as+) left and right, and between respectively every a magnetic pole (N) and a magnetic pole (S), equally wherein each magnetic pole (as N) left and right is each adjacent with its different pole (S), it is middle respectively every electrode (+) electrode (-), such structure forms the regular neat crossing band of electricity, magnetic line of force of electromagnetic field in this water transversely according to the left hand rule of electromagnetic power, can produce unidirectional current simultaneously.
Crossing in water with the magnetic line of force of generation arc in magnetic field between electric wireline that after energising, electric field produces arc between positive and negative electrode and (N, S) magnetic pole, directly produce suitable, backward flow dynamic, this is that one is attached to the invisible power laterally existing outside moving body (supporting body) top layer, the adjustment positive and negative direction of electrode or the N of electromagnetic pole, S direction (permanent magnet inconvenience) flow water backward, as an electromagnetic power level structure.Electromagnetic power level, because be invisible power, can not produce mechanical damage and resistance.Electromagnetic power level structure is transversely arranged on moving body (supporting body) surface can be a straight line, also can inside and outside bend to U-shapedly, even docking is linked to be inside and outside ring-type.Such electromagnetic power level structure under water can larger distance in operation or pipeline, channel transportation power system multipole discharge, can, separately as power, also can be used as auxiliary power.
Here it should be noted that growing up in the length of electrode of magnetic pole is to produce not electricity consumption of magnetic force because of permanent magnet, after electromagnet energising, produce magnetic force little power consumption; The pole-face of electrode magnetic pole is all on the surperficial same plane of moving body (supporting body), be because Electric and magnetic fields in electric wireline and magnetic line of force in the time just leaving electrode or magnetic pole all perpendicular to electromagnetic pole surface, then there is the individual very similar radian of heteropole that leads to, work as like this electric wireline and magnetic line of force distribution up and down of joining in water more even, the power current that produce are just more even; The same equidistant discharge of electrode magnetic pole is also that to consider that electric wireline and magnetic line of force joining distribute in transverse distance comparatively even, and the flow dynamic producing is more even.By contrast the pole-face of electricity, magnetic pole wider and between distance more greatly, the thickness of the current that produce is just large, on the contrary the width of electromagnetism pole-face is narrower, apart from less, current thickness is more thin more presses close to surface and flow velocity more hurry up.
The length of electrode, magnetic pole and wide size particularly separately the distance between width they all should according to vdc in water because of conductivity water temperature and depth generation current, the magnetic force that magnet produces and the current of water generates of living in, actual conditions, COMPREHENSIVE CALCULATING, experiment are determined.In general, the electrode of same electromagnetic power level, the width separately of magnetic pole so that distance are the same, but in the time there is horizontal and vertical bending situation or meet extraordinary circumstances in surface laterally arranged side by side, width separately of electricity, magnetic pole, distance so that length equidimension all can change as required.
People know, are to be directly proportional to the product of two magnetic pole and magnetic field intensity about the computing formula of magnetic force, with square being inversely proportional to of two pole pitch.When this has just determined to be used as power about magnetic field, the relative distance between its two magnetic pole is not too large, comprises and is exclusively used in the liquid electro-magnetic pump of conduction, and the work done cross-sectional area of electro-magnetic pump can not be large.And the work done principle of electromagnetic power level is same with electro-magnetic pump, but what electromagnetic power level had been launched electro-magnetic pump greatly can work done scope, as 1. if the electromagnetic power level of interior ring-type, the work done cross-sectional area that can strengthen electromagnetism is 2. simultaneously if electromagnetic power level is arranged in a straight line, and electromagnetism exposes outside, and will to make the hydrodynamic force of electromagnetism be exposed at external for bent arrangement.These are the peculiar invisible hydrodynamic forces of electromagnetic power level, and electro-magnetic pump is not in the cards.
Here the position that should be noted that the moving body (supporting body) that electromagnetic power level is positioned material is in a big way nonconducting insulator and is non-magnetic material, the magnetic material of electromagnetic power level magnetic part can be all permanent magnet, also can be electromagnet, but sure is, magnetic force that electromagnet produces is strong, and namely producible current are powerful.In addition except electrode to water conducting surface require electric conductivity well, all contact surfaces of other aspects and electromagnetism all must be in state of insulation to outside.Also must be the stable conductive material that attack does not change to the electrode material of water conduction in addition.
Accompanying drawing 5 (a, b, c, d) is four kinds of basic structure sketches that put in order of electromagnetic pole in electromagnetic power level, and magnetic part is wherein that permanent magnet or electromagnet all can.What wherein there is no conductive coil is permanent magnet, what contain conductive coil is electromagnet, the position of conductive coil in soft magnetic bodies can be determined according to design, the pole-face of the electrode magnetic pole wherein having on cross-sectional plane has projection, but along see on service direction be still straight, can not produce equally resistance, all can be used as underwater engine.
Accompanying drawing 5 magnetic motive force levels (e) are the outwardly-bent U-shaped schematic diagram that is arranged in of electromagnetic power, and electromagnetic power level (f) is arranged in U-shaped schematic diagram for electromagnetic power curves inwardly.
The outwardly-bent electromagnetic power level that is arranged in U-shaped can be used for moving body in water and, as naval vessel part below the water surface, arranges as operation power.
The electromagnetic power level that is arranged in U-shaped that curves inwardly can be used for the discharge such as sewage, water channel, as power step by step.
Accompanying drawing 5 electromagnetic power levels (g) are the schematic diagram (not necessarily positive annulus) of electromagnetic pole continuous arrangement the electromagnetic power level that connects into ring-type that curves inwardly.Can be used for submarine pipeline transport, larger distance can continuous blow-down as the pipeline transportation of sewage, seawater, the lower ore in sea, also can be used in afflux cover draining as operation power, and the outwardly-bent ring-type (not necessarily positive annulus) that connects into of the electromagnetic pole continuous arrangement of electromagnetic power level, can be used for complete moving body in water as power, closer distance continuous arrangement (not producing phase mutual interference with electromagnetic power level is as the criterion).Electromagnetic power level be arranged in the surface of moving body under water or supporting body, be not limited to just justify square etc.If electromagnetic capability powerful (reaching superconduction) can be realized high running velocity.
In accompanying drawing 5, electromagnetic power level (h) is the schematic cross-sectional view of permanent magnet N, the length flat magnet of S magnetic pole on large face.The N of permanent magnet wherein, S pole surface in turn, continuously equidistant sticky suction in soft magnetic bodies.This is also the one of electromagnetic power level.
For reducing the cross-sectional area of moving body under water, moving body under water can be made to barrel mast shape tandem junction ship in column, row boat, wherein electromagnetic power level can be as auxiliary power on each joint, and this types of transportation speed is very fast and energy-conservation.
Invisible afflux electromagnetism top layer exclusion operation actuating unit groundwork technical scheme under water: before moving body head electromagnetic power level step by step small distance arrange backward, when work done, just form and be attached to moving body top layer face flow dynamic, Here it is invisible electromagnetism top layer actuating unit.Pointed nose continuous arrangement backward with this electromagnetic power level structure from moving body, can continue to arrange backward through moving body maximum cross section, is even aligned to the postmedian composition invisible afflux electromagnetism top layer exclusion operation under water actuating unit moving body of moving body.Its under water running velocity be exceedingly fast, the USO that can reach people's legend is such, this is the invisible power being attached on moving body top layer, also the same invisible electromagnetism top layer actuating unit of direction that is following quick operation study under water also can be applied in present naval vessel and Submarine, torpedo etc., the lower apron surface (not changing under existing appearance) of moving body.If afflux cover is considered as overlapping interior exclusion, electromagnetism top layer power can be described as the front off-balancesheet eliminating of the body resistance of moving body so.
Electromagnetism top layer operation actuating unit the most outstanding feature compared with afflux cover exclusion is the huge profile of having removed afflux cover, has also avoided suspended matter in water to cause the stifled stagnant of water stream channel simultaneously.
Use the groundwork of electromagnetism top layer exclusion actuating unit operation under water to can be made into polytype performer (brief description of the drawings) under water.
Accompanying drawing 6 is the basic structure principle sketch of invisible afflux electromagnetism top layer power exclusion operating unit under water, and the electromagnetic power level on it is outside non-annular.The edge of its cross-sectional plane of operating unit in this future should be sharp jujube core, the external form of rhombus, also can make prolate or even butterfly.Its running velocity is exceedingly fast and can compares favourably with UFO.
Accompanying drawing 7 is the comparison diagram that resistance is got rid of in electromagnetism top layer exclusion actuating unit and modern propulsive effort extruding operation.Wherein a is modern rear-guard power, and b is electromagnetism exclusion operation power.
Accompanying drawing 8 is for being positioned on the electromagnetism top layer actuating unit simplified schematic diagram of Modern Ships underwater surface part.
Accompanying drawing 9 is for being positioned on the lip-deep electromagnetism of modern Submarine top layer actuating unit simplified schematic diagram.
Accompanying drawing 10 is the electromagnetism top layer power schematic diagram under shallow draught vessel.
Invisible electromagnetism top layer power under water, can exempt the interference injury of suspended matter in the huge profile of afflux cover and water, electromagnetism top layer power under water on moving body from operation front, there is a zone of negative pressure in each powered stage front, entirety is negative pressure, and forms the zone of negaive pressure.This negative pressure active suction is except the resistance water in front just; From moving body rear, each electromagnetic power level and overall malleation, form malleation layer, is to promote exclusion limit, moving body limit by the reaction thrust of malleation to move ahead feature: electromagnetic power draining noiselessness does not produce the spray simultaneously.
Here it should be noted that minor increment between electromagnetic power level does not produce mutually electromagnetic interference with two powered stages and is as the criterion.In electromagnetism top layer actuating unit on moving body because be the process that cross-sectional plane expands backward to moving body maximum cross section from the most front tip, each electromagnetic power level should be not the same, wherein the electrode at forward tip place and the distance of magnetic pole want large, like this, the flow dynamic layer of tip wants thicker, and near and to be between the electromagnetism level of maximum cross section distance less, it is thinner that its flow dynamic layer is wanted, but water flow velocity height is so comparatively reasonable.
Two. the explanation of integrated technology scheme:
The outward appearance of the afflux cover of the actuating unit of afflux exclusion operation is under water straight sleeve shape, its service direction appearance is straight, cross-sectional plane outside geomery is identical everywhere for it, and be totally greater than and similar in appearance to the front maximum cross section of moving body part, afflux cover advances the mouth of a river before the head of moving body, afflux cover shape of cross section is to determine according to the situation of the shape of moving body lower apron the maximum cross-section area position, dynamic structure and relative water outlet, and afflux cover also can show as the multiple exclusion such as downside or both sides and U-shaped (water) form.
In modern water, aircraft can be divided into the two large classes such as the naval vessel of the water surface and the torpedo Submarine below the water surface substantially, simultaneously again because needs separately etc. are made the body that comes in every shape and vary in size, and because of dynamic structure difference, not integrating on an equal basis of work done area, shape, size and riding position, under water in afflux exclusion operation actuating unit, show on the cross-sectional area of afflux cover and consider also to can be made into surrounding draining except an entirety: downside draining, the various ways such as both sides draining and U-shaped draining, as naval vessel of the water surface etc.But as Submarine etc. under water moving body except surrounding draining, also can adopt both sides or upper and lower sides draining etc. (being mainly to consider symmetry), outside on afflux cover cross-sectional plane, be all similar according to the maximum cross-section area before moving body and cross-sectional plane outside, and be approximately parallel to the limit of moving body part the maximum cross-section area in water.Before can ensure like this operation time, can get rid of resistance and ensure that again the lateral surface while operation no longer produces resistance.
Accompanying drawing 12 is single screw power before ship, water outlet U-shaped draining schematic diagram after afflux cover before maximum cross section.
Accompanying drawing 13 is water outlet downside draining schematic diagram before maximum cross section after three screw propeller power side by side in downside afflux cover before ship.
Accompanying drawing 14 is two screw propeller power side by side in the each afflux cover of the front both sides of ship, and rear water outlet is front both sides draining schematic diagram in maximum cross section.
Accompanying drawing 15 is enclosed within small boat bottom side, two kinds of beneath side draining schematic diagrams taking electro-magnetic pump principle as power for afflux.
The water stream channel that has cross-sectional area to dwindle in the mouth of a river cross-sectional area inwards that advances of afflux cover.In afflux cover, advance simultaneously and also contain because draining produces current and accelerate in the cross-sectional area inwards of the mouth of a river, water stream channel cross-sectional area dwindles and the cross-sectional area of the moving body abdicating, strengthen.We know same displacement, after water stream channel is diminished, that local water flow velocity will be accelerated, the cross-sectional area that is to say required water stream channel in the time that current accelerate can dwindle, and Here it is accelerates at afflux cover internal cause current the cross-sectional area that can abdicate to moving body, sees accompanying drawing 11.
Accompanying drawing 11 is for current acceleration and can stay area relationship schematic diagram.From figure, we can see when the water of 1 times of flow velocity enters afflux cover and advance the mouth of a river while accelerating to 2 times of flow velocitys, reserve 1/2 cross-sectional area can to moving body (main body), in the time that current accelerate to 3 times of flow velocitys, its water stream channel cross-sectional area is reduced to 1/3, can reserve 2/3 cross-sectional area to moving body
In general, the mean flow rate of water on place's cross-sectional plane wherein on the mean flow rate ÷ water stream channel that afflux cover advances on mouth of a river place cross-sectional area, be exactly total all the other areas of ratio of the shared cross-sectional area of this place's water stream channel all can be considered the cross-sectional area of abdicating main body.
On water stream channel, be equipped with the dynamic structure of draining backward, because of the work done mode difference of dynamic structure, the shared shape of cross section difference of its work done, the size of the shared cross-sectional plane of work done is simultaneously also different, and the inwall of afflux cover can increase its cross-sectional area at the location-appropriate of corresponding dynamic structure and seal as a supplement fixing.Because of dynamic structure difference, and generally little with respect to moving body, can lay separately, for capable of increasing water discharge capacity also can be laid side by side, as also connected in order to strengthen its dynamics, at this moment the water stream channel in corresponding afflux cover can be made independent pipeline, can be also tubulose side by side.The riding position of dynamic structure can according to circumstances be placed in before the front maximum cross section of moving body, the position on maximum cross section, or moving body in, after to produce best power source effect, require the cross-sectional area of water stream channel to be not less than the work done area of dynamic structure.The power water flow effects that can ensure like this work done reaches best.
The technical scheme of relevant dynamic structure is:
(1) when the dynamic structure of draining is screw propeller backward in afflux cover, excessively after screw propeller, perpendicular flow deflector will be set, perpendicular flow deflector is to erect at prop shaft in the direction of heart in principle.Perpendicular flow deflector front portion has complies with the radian of accepting current, accepts the current with cyclovergence after screw propeller to take advantage of a situation, after just making it to flow to.As a set of power unit, more than screw propeller power can according to circumstances arrange two covers a set of or arranged side by side in an afflux cover.
(2) when in afflux cover, the actuating unit of draining is electromagnetic power level backward, electromagnetic power level can be according to circumstances (if in be linked to be ring-type as a power unit, as can be side by side in a cover for capable of increasing water discharge capacity) as being the use of can two-stage connecting above that builds up speed.Electromagnetic power level also can be arranged on outside afflux cover and on moving body.
(3) when in afflux cover, the dynamic structure of draining is electro-magnetic pump backward, (being characterized as of electro-magnetic pump is respectively equipped with (N) magnetic pole and one (S) magnetic pole on water stream channel inwall both sides, and the vertical direction of co-located is respectively equipped with one (+) electrode and one (-) electrode, with the electric wireline of electric field and the magnetic line of force in the magnetic field generation flow dynamic that intersects vertically, such structure is as a power unit).According to circumstances can use separately, as for capable of increasing water discharge capacity also can overlap on an interior transversal plane side by side and use at afflux, as for building up speed and can connecting use.The magnetic part of electro-magnetic pump can be according to circumstances permanent magnet, can be also electromagnet.
(4) in afflux cover, the outer dynamic structure of draining backward of cover can be that above (1) (2) (3) are any or according to circumstances combine.
Discharge generation operation power at current water outlet after afflux cover of crossing in afflux cover after dynamic structure.The rear water outlet of afflux cover can be in water before the front maximum cross section of moving body head, on the position of maximum cross section or even afterbody of the postmedian of moving body.Its technical scheme is:
(1), when after afflux cover, water outlet is before the front maximum cross section of moving body, rear water outlet can be established horizontal flow deflector, flows out so that outlet current are close to along moving body maximum cross section backward as far as possible.If afflux cover cross-sectional area is more than moving body the maximum cross-section area twice, can consider not establish horizontal flow deflector.
(2) after afflux cover, water outlet is in the time of moving body tail rear portion, and in it, the cross-sectional plane of water stream channel will be had the area of expansion by interior water outlet backward, can ensure that the current of discharging are as far as possible close with the steady water condition of periphery.
If when after afflux cover, water outlet is before the front maximum cross section of moving body, total cross-sectional area of afflux cover and length, outward appearance, cumulative volume just can be made to such an extent that be not large so especially, although the efficiency speed of a ship or plane is more many by force than modern rear quarters power, be only suitable for the unhappy cargo ship of the large-tonnage speed of a ship or plane.The water flow velocity backward that the water flow velocity of rear water outlet produces than rear-guard power has low possibility.
If when after afflux cover, water outlet is on the front maximum cross section of moving body or in the middle part of moving body, the cross-sectional area maximum of afflux cover.Outward appearance volume at corresponding length lower header cover is many greatly, but the efficiency of same Power operation body, and the speed of a ship or plane is opened stronger before moving body maximum cross section than rear water outlet.Thereafter it is less that the current that water outlet flows out are backward wanted, and the water of rear water outlet cross-sectional area is out stayed original place afterwards theoretically, and flowing rearward is the amount of moving body maximum cross section ponding.
In the time of the tail rear portion of water outlet after afflux cover at moving body, the cross-sectional area of afflux cover is also maximum, and length is also the longest, and outward appearance volume is also that very huge (compared with moving body) becomes a straight-tube shape, but its efficiency under same power, the speed of a ship or plane are best.Thereafter the current that water outlet flows out are backward identical or micro-large with the front line speed of moving body in theory, that is to say and substantially can't see from the side mobile backward current.At this moment also can say that afflux cover and moving body unite two into one and become one.Because whole outward appearance is a large straight tube, water is the vertical discharge that sucks from inside.This is that the Utopian depth of water hydraulic pressure that is not subject to limits, and has at a high speed, the operational effect of efficient, noise little (noiselessness), the spray little (without the spray).
If aboard ship or in afflux cover used side by side, and screw propeller is during as dynamic structure, may exist power part office afflux cover inwall to shrink power clear area excessive and with angle.Can establish current through hole herein.It is characterized in that straight hole hole shape, connect the outer front and back of dynamic structure water stream channel, be that the siphon action that utilizes power current to produce is taken away part water from power side, thereby reduce the resistance that this part cross-sectional plane produces.(see accompanying drawing 10,11,12 in opening)
If naval vessel is equipped with under water afflux exclusion operation actuating unit, afflux cover advances, and should to remain on the water surface following constant at mouth of a river place.Its carrying position is placed on the middle rear of ship.Can ensure so the normal operation on naval vessel.
