Cylindrical copper-alloy netting net cage for aquaculture

Abstract

The invention relates to a cylindrical copper-alloy netting net cage for aquaculture. The cylindrical copper-alloy netting net box adopts a high-strength single-dead-knot polyethylene-fiber net, a high-strength polyamide warp knitting net and a copper-alloy rhombic net and is characterized in that a buoyancy system of the net cage is in a combined structure of black high-density polyethylene double floating pipes and cylindrical floaters; a netting system for the net cage consists of a double-layer synthetic-fiber netting as a netting I, a copper-alloy rhombic net as a netting II and a high-strength polyamide warp knitting net as a combined netting for the bottom of a net cage body; the netting I and the netting II of the net cage body are flexibly connected by a longitudinal netting; side bolsh lines and lacing lines are assembled on the netting for the bottom of the net cage body, and horizontal lines and vertical lacing lines are arranged on the netting on the side surface of the net cage body; the combined netting for the net cage body is hung on an armrests and a floating pipe inner frame of a net cage frame; an outer frame of the floating pipe frame is connected with a floating rope frame of a fixed mooring system by mooring ropes, and the fixed mooring system of the net cage is used for fixing the floating rope frame in the sea areas for aquaculture by anchors, wood piles, anchor ropes, floating balls and floating ball connecting ropes.

Description

technical field [0001] The invention relates to a cylindrical cage for seawater culture in the technical field of agricultural science and aquatic products. Background technique [0002] Seawater cages are an important part of my country's marine fisheries. Seawater cages can be divided into cylindrical cages, square cages, spherical cages and conical cages according to their frame shapes. The complete set of equipment and breeding technology for cylindrical cages comprehensively applies multi-disciplinary technologies such as new materials, marine engineering, electromechanical instruments, automatic control technology, environmental protection, feed nutrition, disease prevention and breeding management, and has simple structure and good wind and wave resistance. Advantages, cylindrical cages are currently one of the main types of domestic deep-water cages. The existing cylindrical cages use common synthetic fiber nets and three strands of common synthetic fiber ropes, wh...

AI Technical Summary

Problems solved by technology

The existing cylindrical cages use common synthetic fiber nets and three strands of common synthetic fiber ropes, which consume a lot of raw materials for the rope nets, and the nets of the nets are seriously stained and adhered in the breeding production, and the water exchange inside and outside the cages is not smooth. Farmers change the nets frequently, which is labor-intensive and affects the normal growth and development of fish and breeding benefits. It is urgent to solve the problems of anti-fouling of nets, low volume retention of the box, drifting of nets, and energy consumption of nets. Problems and frame fracture problems, these problems are technical problems that have not been solved for a long time in this field, and it is urgent to improve the level of cage facilities and equipment, so that the cages have better antifouling function, lower energy consumption, and smaller net clothing Horizontal drift, high tank volume retention rate
