Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
As shown in Figure 1, a kind of biological quality monitoring shrimp sample collecting apparatus comprises the first pull rope 4a, the second pull rope 4b, gravitation ball 12, bracing frame 1, shrimping cylinder 2 and the automatic releasing device 3 be arranged on shrimping cylinder.Shrimping cylinder is netted shrimping cylinder.One end of first pull rope is connected with bracing frame.Bracing frame is provided with vertical stop collar 7.Vertical stop collar circular in cross-section.Bracing frame comprises four around the uniform vertical support bar of vertical stop collar circumference.The bottom of vertical support bar is provided with stable counterweight 1a.
Shrimping cylinder is cylinder.Shrimping cylinder is plugged in vertical stop collar.The closed at both ends up and down of shrimping cylinder.The lateral surface top of shrimping cylinder is also positioned at above vertical stop collar and is provided with upper limit position block 6.Shrimping cylinder medial surface top is provided with upset balancing weight 5.The conical limit guide pin bushing 10 that cross-sectional area reduces gradually is provided with from bottom to top in the middle part of shrimping cylinder inner bottom surface.The cross section of conical limit guide pin bushing is circular.The both ends open up and down of conical limit guide pin bushing.The shrimp-entering mouth 11 corresponding with the lower port of conical limit guide pin bushing is provided with in the middle part of shrimping cylinder bottom surface.
Be provided with the buoyant device 9 that shrimping cylinder can be made to float in shrimping cylinder, and buoyant device is fixedly installed on the lower end of shrimping cylinder.Buoyant device is annular buoyancy ring, and annular buoyancy ring set is located on conical limit guide pin bushing.
The gravity of gravitation ball is greater than buoyancy.Gravitation ball is baton round.The external diameter of gravitation ball is greater than the internal diameter of conical limit guide pin bushing upper port and is less than the internal diameter of conical limit guide pin bushing lower port.In the present embodiment, the external diameter of gravitation ball is less than the half of the internal diameter of conical limit guide pin bushing lower port.Gravitation ball is positioned at below the upper port of conical limit guide pin bushing, and gravitation ball is connected with shrimping cylinder inner top surface by connecting line 8.The length of connecting line is less than the spacing between shrimping cylinder upper/lower terminal.In the present embodiment, when gravitation ball is in vertical suspension status, the part in gravitation ball is positioned at the below of conical limit guide pin bushing lower port, and another part is positioned at the top of conical limit guide pin bushing lower port.
As shown in Figure 1 and Figure 2, automatic releasing device 3 comprises the position-limiting drum 39 being vertically arranged on shrimping cylinder inner top surface, be arranged on the side surface upper part of shrimping cylinder and the horizontal guide pin bushing 31 be positioned at below vertical stop collar, slidably be arranged on the spacing pin 32 in horizontal guide pin bushing, to be arranged on spacing pin lateral surface and to be positioned at the collar stop 34 of shrimping cylinder, being set on spacing pin and Compress Spring 33 between horizontal guide pin bushing and collar stop and be hinged on the touch pole 36 of limiting block boom end.One end of horizontal guide pin bushing flushes with shrimping cylinder lateral surface, and the other end extends to toward in shrimping cylinder.One end of spacing pin can move to outside shrimping cylinder along horizontal guide pin bushing.Spacing pin is arranged with cutting ferrule 35, and this cutting ferrule is fixed on the medial surface of shrimping cylinder by connecting rod.Cutting ferrule and horizontal guide pin bushing are positioned at the relative both sides of collar stop.Touch pole and horizontal guide pin bushing are positioned at the relative both sides of collar stop.Touch pole is provided with spacing fixture block 37.Vertical stop collar lateral surface is provided with dodges through hole 38.This dodges through hole and horizontal guide pin bushing is oppositely arranged.Dodge through hole and horizontal guide pin bushing is positioned at sustained height.Touch pole is through dodging through hole.When spacing fixture block is resisted against on position-limiting drum lateral surface, one end of spacing pin moves to outside shrimping cylinder.When collar stop is resisted against on cutting ferrule, the limiting block boom end near vertical stop collar moves in horizontal guide pin bushing.The lower ending opening of position-limiting drum.Be positioned to dodge above through hole and be provided with bait pouch 310 in position-limiting drum.Bait pouch is suspended in position-limiting drum by connection cord.LED 311 is provided with in position-limiting drum.LED is positioned to be dodged above through hole.One end of second pull rope is connected with shrimping cylinder.Bait pouch is built with bait for luring shrimp material.
The specific works process of biological quality monitoring shrimp sample collecting apparatus of the present invention is as follows:
The first, as shown in Figure 1 and Figure 2, be resisted against on position-limiting drum lateral surface by the spacing fixture block on touch pole, now one end of spacing pin moves to outside shrimping cylinder, and spacing pin is positioned at below vertical stop collar.
The second, placed under shrimp sample collecting apparatus in water-bed (seabed) by the first pull rope or two pull ropes.After placing the bottom under shrimp sample collecting apparatus, shrimping cylinder is erected at the bottom (as shown in Figure 1) by bracing frame.
3rd, when shrimp is entered into after in shrimping cylinder by shrimp-entering mouth, due to luring of bait pouch and LED, shrimp will be stretched into by position-limiting drum lower port, and the touch pole now in position-limiting drum is by up jack-up, and spacing fixture block is thrown off;
Then, at the effect lower limit pin of Compress Spring toward interior movement, until collar stop is resisted against on cutting ferrule, the limiting block boom end now near vertical stop collar moves in horizontal guide pin bushing;
Again then, under the effect of buoyant device, shrimping cylinder floats, when shrimping cylinder floats up to after above vertical stop collar, be fixedly installed on the lower end of shrimping cylinder due to buoyant device and coordinate upset balancing weight, now generation upset makes shrimp-entering mouth upward by shrimping cylinder, and gravitation ball under Gravitative Loads by shutoff conical limit guide pin bushing, thus avoid the shrimp of shrimping cylinder IT to be run away by shrimp-entering mouth.
Finally, shrimping cylinder floats up to the water surface.
4th, bracing frame and shrimping cylinder can be regained by the first pull rope and the second pull rope by operator.Thus shrimp sample collecting apparatus of the present invention is not only easy to operate, and automatically can float after catching shrimp, realizes automatically sampling.
