Floating body structure for sinking-floating deep sea airbag cultivation net cage

Abstract

The invention relates to a floating body structure for a sinking-floating deep sea airbag cultivation net cage. The floating body structure comprises floating body units and combining flanges, whereinthe floating body units are connected through the combining flanges to form an annular structure; and each floating body unit comprises a sinking-floating airbag and two skeleton airbags, the sinking-floating airbag is located in the middle, the two skeleton airbags are arranged on two sides of the sinking-floating airbag side by side, the sinking-floating airbag and the skeleton airbags are fixed through hoops, the skeleton airbags comprise inner skeleton airbags and outer skeleton airbags, the sinking-floating airbag is a single-layer airbag, the inner skeleton airbag and the sinking-floating airbag are filled with air, the spaces between the outer skeleton airbags and the inner skeleton airbags are filled with water, and the axes of the skeleton airbags and the sinking-floating airbagare mutually parallel and are located on the same surface. According to the floating body structure, the smoothness of the cultivation net cage during deep sea cultivation can be realized, and the cultivation net cage is capable of effectively defending the impact of typhoon and can sink and float in seawater, so that the damaging of the whole net cage caused by stormy waves is avoided, and the service life of the cultivation net cage is prolonged.

Description

technical field [0001] The invention relates to the technical field of marine fish farming, in particular to a structure of a sinking-floating deep-sea air bag culture cage floating body. Background technique [0002] Deep-sea aquaculture cages refer to aquaculture cages that can be used in relatively deep sea areas (generally, the water depth of the sea area is >20m). It is a brand-new aquaculture facility developed in the past ten years. There are Norway, the United States, Chile, Scotland, Canada, Greece, Turkey, Spain, Australia and other countries. [0003] Deep-sea cages can be divided into floating cages and lifting cages. Lifting cages float on the water surface when the weather is calm, and sink underwater when a typhoon comes to avoid the impact of wind and waves. Sea cage culture is currently the In a mature traditional industry, engineering plastic pipes with good mechanical properties and economical efficiency are generally selected as the floating frame mat...

Problems solved by technology

[0005]The plastic pipes used in the existing floating body structure, plastic foam is put into the pipes to form a certain buoyancy and realize deep-sea aquaculture, but in the actual aquaculture process As the service life increases, plastic pipes are prone to damage, and they will also be damaged when encountering wind and waves at sea. After the foam inside leaks out, it will cause seawater pollution, and it is not easy to salvage, seriously affecting fishery production
