Large non-metal net cage platform system suitable for deep sea fishery breeding

Abstract

The invention discloses a large nested non-metal net cage platform system suitable for deep sea fishery breeding. The system comprises an external maintenance and protection structure, an upper operating platform and an internally nested non-metal breeding net cage structure which are all made of non-metal materials, wherein a buoyancy and supporting platform of the external structure, internal net cage floating frames, sleeve connecting pieces, an upper protective fence, the operating platform, a lower pressure-resistant floating body, a netting and connecting mooring ropes are all made of non-metal composite materials, the advantages of corrosion resistance, large buoyancy, light weight, simple and flexible connection, good structural coupling, low cost and the like are achieved, and thediameter of a net cage can reach tens of meters. The non-metal floating frames are formed by connecting composite material structures so as to adapt to complex stormy wave conditions, provide buoyancy and support and reduce waves; the pressure-resistant floating body maintains the shape and volume of the netting; an anchoring system limits the position of the net cage through an anchor rope, an anchor chain and an anchor; and the defects of a traditional HDPE net cage and a large metal net cage are overcome, and a flexible breeding space and a flexible operation manner are provided.

Description

technical field [0001] The invention relates to the field of deep-sea aquaculture, in particular to a large-scale non-metal net cage platform system suitable for deep-sea fishery aquaculture. Background technique [0002] The ocean is the "blue granary" for human beings to obtain high-quality protein. Since 1990, my country's seafood farming has been ranked first in the world. Among them, the development of offshore cage culture fishery has promoted the diversified development of my country's fishery breeding and driven the output of marine fishery. promote. However, at present, my country's coastal cage fish farming has long been limited to high-density farming in coastal waters, which is likely to cause environmental pollution and water quality deterioration, resulting in increased pest damage and reduced fish quality. In recent years, the country has vigorously supported the development of deep-sea cage culture. , but the strength and rigidity of the traditional HDPE cage ...

Problems solved by technology

However, at present, my country's coastal cage fish farming has long been limited to high-density farming in coastal waters, which is likely to cause environmental pollution and water quality deterioration, resulting in increased pest damage and reduced fish quality. In recent years, the state has vigorously supported the development of deep-sea cage culture. , but the strength and rigidity of the traditional HDPE cage structure are far from meeting the complex and changeable marine environment requirements of deep-sea fisheries, and the large steel structure cages evolved from offshore oil platforms have the disadvantages of heavy structure, high cost, Rigid structures that are prone to corrosion, difficult to install, and large-scale movements, and flexible structures such as nets, have poor adaptability, etc.
