Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquaculture equipment, and in particular to a net cage structure capable of preventing impact of sudden flow. BACKGROUND

[0002] At present, the traditional truss type net cage is of an integral fixed size type, and cannot be disassembled into independent and combinable modules or components to realize independent construction and maintenance, thereby causing bottlenecks in production efficiency, construction cost, development cycle and the like.

[0003] The traditional truss type net cage is mostly of a circular three-dimensional structure or a square rectangular three-dimensional structure, and such a structure determines that the net cage will face strong sea current impact, causing the water exchange speed in the net cage to be accelerated, thereby reducing the survival probability of fish, and when the environmental sea current speed increases, the stress of the net cage increases quickly, and the resistance capacity is poor, so that the traditional net cage is difficult to adapt to the harsh sea current environment.

[0004] The traditional deep-sea aquaculture truss type net cage is formed by surrounding and enclosing the cultivation water space through a truss and a net, and the entire net is wrapped and fixed, and the unit cultivation water cost is composed of two parts of the cost of the truss and the net, which is higher than the unit cost of the cultivation water formed by surrounding and enclosing through the traditional HDPE net cage.

[0005] The weather at sea changes rapidly, and the lifting speed of the net cage has a significant impact on its emergency escape ability. The lifting of the traditional net cage needs to be completed by adjusting the ballast water through cooperation of multiple people, which is time-consuming and complicated to operate, and at the same time, the stability of the net cage is poor during the lifting process.
