Wave-resisting net cage framework

Abstract

The invention discloses a wave-resisting net cage framework, which comprises an upper-layer framework and a lower-layer framework, wherein the upper-layer framework and the lower-layer framework are square, the upper-layer framework consists of an inner framework and an outer framework arranged outside the inner framework in parallel, the inner framework and the outer framework are connected through a first connecting piece, the lower-layer framework is a single framework and is arranged below the outer framework in parallel and is concentric with the outer framework, the outer framework and the lower-layer framework are connected through a second connecting piece, and the upper-layer framework and the lower-layer framework respectively comprise sealing tubes. Through the double-framework upper-layer framework and the single-framework lower-layer framework, the buoyancy of the upper-layer framework is greater than that of the lower-layer framework, the stability of the whole net cage in typhoon or gale wave is increased, so that the whole net cage can be still stable under wave impact, and the oscillating of the net cage can be remarkably reduced; and the upper-layer framework is a double-framework, the inner framework is used for hanging a net bag, and the outer framework plays a role in enhancing wave reduction effect, so as to prevent surge from damaging fish cultivated in the net cage.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a wind and wave resistant net cage frame. Background technique [0002] As my country's fishery development strategy has shifted from fishing-based to aquaculture-based, my country's sea and freshwater cage aquaculture industry has shown a rapid development trend with the support of governments at all levels. Along with the enlargement of breeding net cages, the quantity and economic value of breeding objects in the net cages are also increasing, and the output value in one net cage varies from hundreds of thousands to several million. Therefore, once the cage ruptures and sinks, it will bring huge economic losses to the breeders. [0003] At present, my country's cage culture is mostly concentrated in the southern coastal areas. These areas are often affected by severe weather such as strong typhoons. When attacked by wind and waves, the entire cage fluctuates greatly with...

AI Technical Summary

Problems solved by technology

These areas are often affected by severe weather such as strong typhoons. When attacked by wind and waves, the entire cage fluctuates greatly with the waves, making the entire cage unstable and swinging up and down greatly, which seriously affects the cultivation in the cage. The normal growth of fish may even cause the farmed fish to be infected with diseases
