Summary of the invention
The objective of the invention is to propose a kind of cross section that facings the wind of regulating automatically is rotating speed thereby makes the more stable perpendicular axis type wind-driven generator blade structure of output voltage.
The perpendicular axis type wind-driven generator blade structure that the present invention proposes, be the concave-convex type fan blade self-regulating structural type in cross section of facining the wind, adopting double-leaf (S type), three blades (human-like) or leafy layout, and be one or more layers stacking pattern, is the novel improvements design of inventor to above-mentioned patent.
Among the present invention, fan blade is formed by 1-3 layer blade stack combinations, and interlayer separates with fan blade frame 1, and its structure as shown in Figure 1-Figure 3.Every layer is assembled on the running shaft of generator by 2-6 blade equal angles.Wherein, each blade vertically is a rectangular, perhaps is other geometrical shapies such as polygonal, and lateral cross section is a camber line shape, or is laminar flow airfoil, and forming the front is convex surface, and the back side is the concaveconvex structure form of concave surface, and whole fan blade can slightly be the camber bending; That each blade rack 1 is provided with is one or more (as 2-6) consumption air door 2 that slip forms, be connected by weak spring sheet (or spring sheet) 3 between every fan consumption air door 2 and the blade rack 1, perhaps consuming air door 2 is connected with blade rack 1 usefulness bearing 4 or axle sleeve, in the joint weak spring sheet or weak spring sheet 3 are installed, are used to regulate the Push And Release of consumption air door; Establish one or more (as 2-6) consumption air regulator 5 in every fan consumption air door 2, and the consumption air regulator can be made into different shape as shown in FIG., with its one or more combinations, every fan consumption air regulator 5 usefulness strong spring sheets or spring sheet 6 are connected with consumption air regulator frame, perhaps consume air regulator 5 and consume air regulator frame axle sleeve in succession, strong spring sheet or strong elasticity sheet 6 are installed, the Push And Release of consumption air regulator 5 during as adjusting high wind in the joint.The fan blade blade face that wind-driven generator is every layer is made up of single fan consumption air door or many fan consumption air doors, the structure of other parts of wind-driven generator and common perpendicular axis type wind-driven generator associated components are basic identical, but do not have the controlling mechanism and the tuning system of complicated controlled wind speed.
Among the present invention, blade structure can have multiple moulding, and as shown in Figure 4, individual blade is triangular in shape, and double-leaf is in the shape of the letter V.As shown in Figure 5, it is tubaeform that individual blade is the plane, and it is tubaeform that double-leaf is biplane.As shown in Figure 6, individual blade is square, and double-leaf is barbell shape, and the centre can not have fan blade.
Among the present invention, also thin-film solar cells can be installed on the blade of fan blade, as solar electrical energy generation.
Among the present invention, the area of consumption air door 2 can be the 90%-110% of blade frame area.
The present invention has made full use of the blade structure new technology that consumption air door (being venetian blind) designs with the characteristic of spring (sheet) or spring sheet.Its working procedure is as follows:
When from the wind of any direction during to fan blade 1, consumption air door (venetian blind) 2 on the convex surface is just blown open (because this moment, the consumption air regulator 5 on the convex surface was inoperative, and the spring sheet 3 of its reverse side is thinner, elasticity is little, consumption air door 2 is just opened by wind easily), wind passes a part from the convex surface consumption air door that is blown open, and the consumption air door 2 of concave surface can not be blown open (because the spring 6 between consumption air regulator and the consumption air door is thicker, elasticity is very big, the consumption air regulator blows not open, so consumption air door 2 is not easy to be blown open), wind just blows the fan blade rotation of concave surface like this.Be contained on the generator 8 by rotating shaft 7, promoted generator 8 generating work.
When the wind that blows was big, the consumption air door 2 on the convex surface fan blade was just opened very greatly, and the wind energy that spills is just a lot, and the consumption air regulator 5 on the consumption wind multiple leaf door of concave surface is just blown open, though very little, have and leak out, the speed that blower fan changes is just big slightly.
When blow rather windy the time, the consumption air door 2 on the convex surface fan blade is just opened maximumly, promptly the right angle is 90 °, the wind energy that spills just at most, and the consumption air regulator 5 on the consumption wind multiple leaf door of concave surface is just blown open greatly, it is more to leak out, the speed that blower fan changes is just big.
When the wind that blows hour, the consumption air door 2 on the convex surface fan blade is just opened greatlyyer, the wind energy that spills is just big, and the consumption air regulator 2 on the consumption wind multiple leaf door of concave surface can not be blown open, the speed that blower fan changes is just slow slightly.
Therefore, the consumption air regulator 2 on the consumption wind multiple leaf door can be regulated wind energy and blow the speed that blower fan rotates, thereby the electric power that generator is sent is comparatively stable.
As shown in the figure, the spring 3 of the one side of facining the wind on the concave surface fan blade a little less than, 6 on the spring of convex surface is stronger.
The core of fan blade rotational structure is to have designed on the fan blade many fan consumption air doors (venetian blind) 2, and the composite structure form of the concave surface spring 3 of the convex surface spring 6 of consumption air regulators 5 of fan more than in door, being provided with and strong elastic and weak elastic force, make more effective being utilized of weak wind (about 1.5 grades) and high wind (more than 11 grades) hurricane energy.Its advantage is as follows:
1, wind power plant compact structure, it is changeable to make specification, and the power generating equipment of different capacity specification can both rotary electrification work under gentle breeze (about 1.5 grades) state, also can continuous operation under hurricane (more than 11 grades) situation.And general perpendicular axis type and horizontal shaft type wind power plant need more than three grades wind energy just can blow the fan blade rotation and work, and when wind-force was crossed more than 9 grades, wind-driven generator just quit work, and to prevent that fan blade from fractureing and generator is burnt out, wind energy utilization is low.Suitable wind ranges is wide so wind power plant of the present invention has, and wind energy utilization is high, the long and high considerable advantage of efficient of generating dutation.
2, compare with wind power plant, be suitable for this blade structure wind power plant with constant power, cheap for manufacturing cost, need not speed regulator and braking device, utility ratio height, easy accessibility, applied widely, do not need directed wind-force field.Can be installed in around roof, the roof, balcony and window are outer etc. outside the street lamp, navigation mark light, car and boat afterbody, highway isolated fence, bridge both sides, building locates.
3, because blade structure of the present invention is special, and it can be inverted or be placed horizontally in the flowing water, utilize the torrent generating of waterfall, brook, river or big river bank, also this power generating equipment can be placed horizontally in the sea level, utilize wave or great waves to generate electricity.
In sum, wind power plant application area of the present invention is extremely wide, no matter island, shore line, vehicle afterbody, city street lamp, fishing boat, mountain area, Plain, desert or the like, and every have the area of wind energy more than 1.5 grades all can utilize its generating.
