Round metal net cage structure and preparation method thereof

Abstract

The invention discloses a round metal net cage structure and a preparation method thereof. The round metal net cage structure consists of net cage body net coat and a net cage frame, and is characterized in that: the net cage body net coat has a combined structure consisting of a superhigh-strength woven net, a metal slant square net and a synthetic fiber net coat; the net coat at the bottom of the body of the net cage is provided with steel ropes which are vertically crossed to form a grid form and is subjected to antifouling treatment by antifouling agent before being arranged on a round high-density polyethylene tube by a high-strength rope; the net coat on the side of the body of the net cage is provided with a horizontal steel rope and a vertical steel rope; the internal and external frames of the net cage are made of round high-density polyethylene double floating tubes; floaters are uniformly distributed below the double floating tubes and along the circumferential direction of the double floating tubes; the net coat with the combined structure of the body of the net cage is hung on the handrest frame of the frames of the net cage and the floating tube internal frame of the net cage; the handrest frame and the upper horizontal steel rope of the first net coat of the body of the net cage are connected; and a connecting rope between the internal frame of the floating tubes and the foam floaters and the lower horizontal steel rope of the first net coat of the body of the net cage are connected. The round metal net cage structure is used for fishing net cages.

Description

technical field [0001] The invention relates to a circular metal cage used in the technical field of fishery engineering. Background technique [0002] Metal cages are an important part of fishery engineering. Metal cages can be divided into circular metal cages, square metal cages, spherical metal cages and polygonal metal cages according to their frame shapes. The circular metal net cage has simple structure and good anti-wind and wave performance, and is an important type of deep-water net cage at present. During the development of the existing circular metal cages, some urgent problems have been exposed, such as the wear and tear of the high-density polyethylene frame and the metal mesh at the mesh opening, the energy consumption of the cage materials, and the volume retention rate of the cage body. Problems and metal wires for metal nets wear each other under the weight of the nets, etc. These problems have not been solved for a long time, and there is a need for a ma...

Problems solved by technology

During the development of the existing circular metal cages, some urgent problems have been exposed, such as the wear and tear of the high-density polyethylene frame and the metal mesh at the mesh opening, the energy consumption of the cage materials, and the volume retention rate of the cage body. Problems and metal wires for metal nets wear each other under the weight of the nets, etc. These problems have not been solved for a long time, and there is a need for a material that can effectively prevent the wear and tear of the metal nets at the frame of the circular metal net cage and the mesh opening, and reduce the wear and tear. Energy consumption, reduce breeding risk, increase box volume retention rate, increase cage system buoyancy retention rate, improve cage culture bait utilization rate and reduce mutual wear of wires for net clothing, improve the level of circular metal cage engineering facilities and equipment method to promote the sustainable and healthy development of circular metal cages
