no. 1 example

[0029] like figure 1 , figure 2 As shown, a laser-assisted fishing device for pond culture includes a strip-shaped PVC float 1, the float 1 floats on the water surface of a pond 4, and the two ends of the float 1 extend out of the two banks of the pond 4 and are perpendicular to the bank of the pond. At least one cable 2 is attached to the float 1, and a laser emitter group 3 is arranged along the cable 2, and the laser emitter group 3 is connected with the laser emitter driving system through the cable 2, and the laser emitter The laser rays emitted by group 3 form a meshed laser grating surface which intersects the bottom surface of the pond. One end of the cable 2 extends to the bank of the pond 4 and is connected to the laser transmitter driving system, which is powered by a battery (or a DC voltage stabilizer connected to an alternating current), and the two are placed on a cart 6 . The laser transmitter driving system includes: a pulse driving system, the pulse drivin...

no. 2 example

[0032] In the first embodiment, the laser rays are unevenly distributed, concentrated in the middle and upper part of the grating surface, and have a good repelling effect on the fish located in the middle and upper part of the pond, but the repelling effect on the fish near the two banks and the bottom of the pond is relatively small .

[0033] So, if image 3 As shown, the difference between the second embodiment and the first embodiment is that the laser emission direction of the laser emitter is vertical and parallel downward, forming a uniform grating surface.

no. 3 example

[0035] The gap between the gratings in the first and second embodiments is relatively large, and sometimes the individual petite fish cannot be completely stopped. Therefore, the following improvements are made on the basis of the above-mentioned laser-assisted fishing device:

[0036] like figure 1 , Figure 4 As shown, the laser emitted by the laser emitter group 3 is parallel and vertically downward. At the same time, by adding a group of horizontal laser emitters, that is, installing a vertically downward cable and a fixed column of the laser emitter in the middle of the original float, Fix the cable and the laser transmitter on the column. The cable is the branch cable 8 of the original cable 2. The two sets of laser transmitters are installed on both sides of the column. When the laser transmitter works, it emits a grid of square grids.

Abstract

The invention relates to a pond culture laser-assisted capturing device and capturing method, which belong to the technical field of fish capture. The pond culture laser-assisted capturing device comprises a long strip-shaped floater (1); the floater (1) floats on the water surface of a pond (4); two ends of the floater (1) extend out of both sides of the pond (4); at least one cable (2) is attached to the floater (1); a laser transmitter group (3) is arranged along the cable (2); the laser transmitter group (3) is connected with a laser transmitter driving system by a cable (2); laser rays transmitted by the laser transmitter group (3) form a laser grating surface; and the laser grating surface is intersected with the bottom surface and two side surfaces of the pond. According to the invention, the pond fish culture capturing labor intensity is greatly reduced, the capturing efficiency is increased, the capturing cost is reduced, large-sized mechanical capturing equipment is not needed in use, operation requirements are greatly reduced, and damages to fishes in the capturing process are greatly reduced.

Description

technical field [0001] The invention relates to a laser auxiliary fishing device for pond culture, in particular to an auxiliary fishing device for intercepting and repelling fish by laser, and belongs to the technical field of fishery fishing. Background technique [0002] Fishing is an important link in fishery production. During the development of pond aquaculture, people generally pay attention to the research of aquaculture technology, and the development of fishing technology is relatively lagging behind. Traditional pond culture pull net fishing operation is to put the fish net from the shore into the pond, usually requires 8 to 12 (4 to 6 people on each side) fishing personnel step on the bottom line of the net while pulling the net (to prevent fish from escaping from under the bottom line) Pulling to the opposite bank, usually the fishing rate of a net pulling operation is 50-70%. The reason is that the whole bottom line of the net cannot be guaranteed to be complet...
