A kind of gillnet that is easy to salvage

Abstract

The invention discloses a gillnet that is easy to salvage, and aims to provide a gillnet that is easy to salvage and can effectively solve the problem that the gillnet is very difficult to salvage when it sinks into the seabed, causing seabed ghost fishing. It includes a square mesh, a number of floats arranged on the upper edge of the square mesh and a number of weight devices suspended on the lower edge of the square mesh through connecting ropes; The top plate of the cylindrical counterweight is an iron plate that is easily corroded by seawater. An insertion hole is provided in the middle of the upper surface of the iron plate, and a sealing ring installation groove is provided on the inner side of the insertion hole. An inflatable sealing ring is provided in the sealing ring installation groove; an annular thinning groove is arranged on the upper surface of the iron plate, and the insertion hole is located on the inner side of the annular thinning groove; The spring, the insertion rod is inserted in the insertion hole, and the inflatable sealing ring is sleeved on the insertion rod.

Description

technical field [0001] The invention relates to a gillnet, in particular to a gillnet which is easy to salvage. Background technique [0002] Gillnet is a rectangular mesh made of one or more layers of plastic filaments, and generally multiple meshes are bonded together. There are multiple floats on the upper edge of the gillnet, and multiple counterweights on the lower edge of the gillnet, so that the gillnet is vertically opened at a position close to the sea level, waiting for fish to swim in and be caught by the net. entangled. [0003] Gillnets are often damaged by the net gear during use and discarded by fishermen in the sea. For these gillnets discarded in the sea, some of the floating balls on the gillnets will fall off and be damaged over time, causing the gillnets to sink to the bottom of the sea under the action of the counterweight; and once the gillnets sink to the bottom of the sea It is very difficult to salvage, causing seabed ghost fishing, which will ser...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a gillnet that is easy to salvage, which can effectively solve the problem that the gillnet sinks into the seabed and is very difficult to salvage in the prior art, causing ghost fishing on the seabed. It is difficult to salvage, causing ghost fishing on the seabed, which will seriously damage the ecological environment of the seabed

The gillnet that is easy to salvage in this scheme can effectively solve the problem that it is very difficult to salvage when the gillnet sinks into the seabed, causing ghost fishing on the seabed, which will seriously damage the ecological environment of the seabed
