Description

Shrimp pond anti-bird device

Technical Field

The utility model relates to an anti-bird device especially relates to an anti-bird device suitable for shrimp pond.

Background

Because individual growth is realized by shelling in the shrimp culture process, shelling is generally finished at the bank side of the pond, so that the shrimp shell can avoid similar attacks, and the shrimp shell is quickly calcified due to the high oxygen content of surface water. Therefore, the shallow water area of the shrimp-farming pond has a plurality of individual shrimps which are in the shelling period and have weak activity, and the individuals are easy to be prey on by birds. The shrimp aquaculture pond is often damaged by the birds preying on the fishes and the shrimps, such as the aigrette and the like, so that the fishes and the shrimps are killed, and the birds shuttle in various water areas, so that the disease sources are easily spread, and the health of the fishes and the shrimps is threatened. Because many birds are animals-protecting and cannot be killed, the birds can only be repelled manually, but the birds have little effect and cannot achieve the purpose of continuous isolation.

The utility model aims at solving the defects existing in the prior art, and providing the bird-proof device which has simple structure and low cost and can better prevent birds such as aigrette from infringing shrimps.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a shrimp pond bird preventing device comprises an isolation net piece and a plurality of supporting mechanisms, wherein each supporting mechanism comprises a first supporting rod and a second supporting rod, the first supporting rod and a horizontal plane form an included angle of 15-25 degrees, the bottom of the first supporting rod is fixed on the side wall of a pond ridge, the top of the first supporting rod is connected with the second supporting rod, the second supporting rod is vertically arranged, and the bottom of the second supporting rod is fixed at the bottom of the pond; a bearing component is arranged between the adjacent supporting mechanisms, the isolation net piece is arranged on the supporting mechanisms and the bearing component, and the front edge of the isolation net piece extends out of the first supporting rod and is vertical to the water surface.

Preferably, the first support bar and the second support bar are connected in a hinged manner.

Preferably, the bearing component is a plurality of parallel steel wires or nylon ropes, and two ends of the bearing component are fixedly connected with the first supporting rod respectively.

Preferably, three parallel arranged steel wires or nylon cords are used.

Preferably, the first support bar is arranged at an angle of 20 ° to the horizontal plane.

Preferably, the shrimp pond bird-preventing device is arranged along the periphery of the pond body.

Preferably, the device also comprises a limiting partition plate, wherein a plurality of through holes are uniformly distributed on the limiting partition plate, the limiting partition plate is vertically arranged in the pond, and the top of the limiting partition plate is contacted with the isolation net piece.

Preferably, the depending front edge of the spacer mesh is 40cm from the surface of the water.

Compared with the prior art, the beneficial effects of the utility model are that: the bird prevention net is convenient to build, simple in structure, convenient to maintain and low in cost, can effectively prevent birds such as aigrette from harming the cultured shrimps, and meanwhile, does not influence normal management operations such as feed feeding.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-2, the shrimp pond bird prevention device comprises an isolation net 3 and a plurality of support mechanisms 2, wherein each support mechanism 2 comprises a first support rod 21 and a second support rod 22, and the first support rods 21 and the horizontal plane form an included angle of 15-25 degrees, preferably 20 degrees. The bottom of the first support rod 21 is fixed on the side wall of the pond ridge 1, the top of the first support rod 21 is hinged with the second support rod 22, the second support rod 22 is vertically arranged, and the bottom of the second support rod is fixed at the bottom of the pond; a bearing component (not shown in the figure) is arranged between the adjacent supporting mechanisms 2, the bearing component is three parallel steel wires or nylon ropes, and two ends of the bearing component are respectively fixedly connected with the first supporting rods 21. The isolation net 3 is arranged on the supporting mechanism 2 and the bearing component, and the front edge of the isolation net 3 extends out of the first supporting rod 21 and is vertical to the water surface. The distance from the drooping front edge of the isolation net 3 to the water surface is 40 cm. The devices are continuously arranged along the periphery of the pond body.
