Ecological suspended silt removal fish tank

Abstract

The invention discloses a suspended ecological silt-removing fish box, which comprises an anchor, a traction chain, a suspended box body and a protection plate. The suspended box body is connected to the top of the anchor through the traction chain, and the protection plate is arranged outside the suspended box body. A fish migration channel and an inner recessed cavity are arranged between the suspended box body and the protection plate. The suspended box body is driven by the thrust on the upper layer of the water area to agitate the silt at the bottom of the water area, so that the water flow carries away part of the silt, and the native cave-dwelling fish is protected. The structure is simple and firm.

Description

TECHNICAL FIELD

[0001] The invention patent relates to a suspended ecological silt removal fish compartment. BACKGROUND

[0002] The river slows down due to damming for water storage, leading to sediment deposition and reservoir capacity reduction. After years, the deposited silt is an ideal place for harmful bacteria and microorganisms to focus and multiply, directly affecting the quality of drinking water, and also depriving native indigenous cave-dwelling aquatic animals of the basic conditions for survival and reproduction, leading to extinction or near-extinction. SUMMARY

[0003] The purpose of the present invention is to solve the existing technical problems, and a suspended ecological silt removal fish compartment is provided.

[0004] In order to achieve the above purpose, the technical scheme adopted by the present invention is as follows: a suspended ecological silt removal fish compartment, comprising: an anchor, a traction chain, a suspended compartment body and a protective plate, the anchor is connected to the suspended compartment body through the traction chain, the suspended compartment body is provided with a protective plate, and a fish migration channel and an inner recess are provided between the suspended compartment body and the protective plate.

[0005] Further, the lower end of the anchor is large at the top and small at the bottom, and the lower end is also provided with a rake-shaped protrusion inserted into the silt.

[0006] Further, one end of the plurality of traction chains is connected to the anchor, and the other end of the plurality of traction chains passes through the protective plate and is connected to the suspended compartment body.

[0007] Further, a sealed suspension cavity is provided inside the suspended compartment body.

[0008] Further, the suspended compartment body is in a cylindrical structure.

[0009] Further, the protective plate is composed of two semicylindrical arc-shaped plates, the openings of the two semicylindrical arc-shaped plates are provided with outer edges, and the two adjacent outer edges are fixed by bolt cooperation.

[0010] Further, a plurality of semicircular strip-shaped fitting protrusions are uniformly distributed inside the arc-shaped plate, a plurality of semicircular strip-shaped fitting grooves are uniformly distributed outside the suspended compartment body, the fitting protrusions are fitted into the fitting grooves from one end of the suspended compartment body, and the fish migration channel is formed between adjacent fitting protrusions.

[0011] Further, a channel is provided on the inner side wall of the fish migration channel, which communicates with the inner recess.

[0012] Further, the suspended compartment body is in a cylindrical structure, the fish migration channel is provided with an inner recess on the inner wall of the fish migration channel.

[0013] Further, the suspension compartment and the protection plate form a cylinder.

[0014] The beneficial effects of the present application are that the thrust on the upper layer of the water area drives the anchor to agitate the silt at the bottom of the water area, and the water flow carries away part of the silt, thereby protecting the native cave-dwelling fish, and the structure is simple and firm.
