Description

High-efficient fish collecting device suitable for cement pond is bred

Technical Field

The utility model relates to a high-efficient fish collecting device suitable for cement pond is bred.

Background

At present, fish culture uses a large amount of cement ponds for culture.

At present, the common mode of collecting the fish in the cement pond is to fish the fish by a fishing net, so that the fish is collected in the fishing net and then is subjected to fishing or specification screening work. This method requires high operation requirements, requires much manpower, and causes great damage to the fish.

The other fish collecting mode is that water is drained to reduce the water level of the fish pond, so that the fishes are concentrated in a relatively small water body and then are fished or screened according to specifications. This method requires much manpower, wastes water resources, and also causes great damage to the fish.

How can overcome prior art's defect, provide a high-efficient fish collecting device who is applicable to cement pond cultivation easy operation, can reduce fish body damage, the technical problem that technical staff in this field promptly solved.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a high-efficient fish collecting device suitable for cement pond cultivation of easy operation, ability reduction fish body damage.

In order to solve the technical problem, the high-efficiency fish collecting device suitable for cement pond culture comprises more than two fish collecting nets; the fish collecting net comprises a frame and a net fixed on the frame; the fish collecting net is rectangular; the frame comprises an upper frame, a bottom frame and two side frames; the frames at the two sides of the fish collecting net are hollow pipes; the length of the frames at the two sides of the fish collecting net is greater than the depth of the water surface of the fishpond so that the frames at the upper side of the fish collecting net are exposed out of the water surface; two adjacent fish collecting nets are inserted into the overhead central tubes of the adjacent side frames through U-shaped rods to be movably connected.

The bottom frame of collection fish net is erect and is equipped with the support frame in order to prevent to empty.

The frame of the fish collecting net is made of a pvc pipe or a zinc-plated pipe.

The netting is a polyethylene net or a stainless steel net.

The length of the upper frame and the bottom frame is 3 meters.

And a reinforcing rod is connected between the upper frame and the bottom frame.

The reinforcing rod is made of a pvc pipe or a zinc-plated pipe.

The reinforcing rod is integrated with the side frame and the bottom frame.

The U-shaped clamping sleeve is clamped with two ends of the U-shaped rod.

Adopt the utility model discloses a structure, owing to including more than two collection fish nets, two adjacent collection fish nets insert adjacent side frame built on stilts heart pipe through the U-shaped pole with swing joint, form the combination fish net, the combination fish net scale can be according to the nimble increase and decrease of pond area. When the combined fishing net works, the combined fishing net is operated by 2-3 persons, water is drained by sticking the fishing net wall at one end of the pool, the side frame of the fishing net is perpendicular to the pool bottom, the bottom frame is stuck to the pool bottom, the upper frame is higher than the water surface, the frames at two sides are stuck to the pool wall, then the combined fishing net is gradually pushed towards the other end of the pool, the fish swarm density is gradually increased, the fish gathering net can be added when the pool is widened in the pushing process, the fish gathering net can be reduced when the pool is narrowed, and when the fish swarm density is concentrated to a desired value, the fishing or screening work can be withdrawn.

The utility model is simple in operation, a plurality of collection fish net can be assembled in a flexible way, can adjust album fish density at will, is applicable to the work of not equidimension cement pond collection fish.

Through experiment, adopt the utility model discloses, can reduce the required manpower of fish gathering more than 30%, fish body damage rate reduces more than 50%, and the unrestrained rate of water resource of fish gathering of drainage reduces more than 80%.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in figure 1, the utility model discloses a high-efficient fish collecting device suitable for cement pond is bred, including more than two fish collecting nets.

The fish collecting net comprises a frame and a net 2 fixed on the frame.

The fish collecting net is rectangular. The frame comprises an upper frame 1, a bottom frame 5 and two side frames 4. The frames at the two sides of the fish collecting net are hollow pipes. The length of the frames at the two sides of the fish collecting net is greater than the depth of the water surface of the fishpond so that the upper frames of the fish collecting net are exposed out of the water surface.

Two adjacent fish collecting nets are inserted into the hollow pipes of the adjacent side frames through the U-shaped rods 3 to be movably connected.

The device also can comprise a U-shaped clamping sleeve which is clamped with the two ends of the U-shaped rod. After the U-shaped rod 3 is inserted into the hollow pipe of the adjacent side frame, the U-shaped clamping sleeves are clamped with the two ends of the U-shaped rod, so that the connection is more stable. The connected fish collecting net can be folded and unfolded around the U-shaped connecting rod, and is more convenient and reliable.

Further improved, the bottom frame of the fish collecting net is provided with a support frame to prevent the fish collecting net from toppling over.

Preferably, the framework of the fish collecting net is made of pvc pipe or zinc-plated pipe material.

Preferably, the netting is a polyethylene net or a stainless steel net.

Preferably, the length of the upper frame and the length of the lower frame are 3 meters. If a fish collecting device of a 100 square meter culture pond: the length of a single fish collecting net is about 3 meters, and the height of the single fish collecting net is about 1 meter.

In order to strengthen the strength of the net, a reinforcing rod 6 is connected between the upper frame and the bottom frame.

Preferably, the reinforcing rods are made of pvc pipe or zinc-plated pipe material.

Preferably, the reinforcing bar is integrally formed with the side frame and the bottom frame.
