Net cage for underwater culture

Abstract

The invention relates to the technical field related to aquaculture, and discloses a net cage for underwater aquaculture, which comprises a base, a supporting rod is fixedly mounted on the surface of the base, a top seat is fixedly mounted at the top end of the supporting rod, a connecting column is fixedly mounted in the middle of the surface of the base, and a fixing rod is fixedly mounted at the top end of the side wall of the connecting column. The protective shell is arranged on the outer side of the filter screen, so that when the filter screen is subjected to strong wind, the fan blades are pushed by water flow to rotate, and the protective shell is contracted, so that the filter screen is wrapped, and the influence of direct impact of external strong wind on the filter screen is prevented; the fan blades continuously rotate, so that small-strength impact on the outer side of the filter screen is achieved, dirt on the outer side of the filter screen is flushed out, cleanliness of the interior of the filter screen is guaranteed, the fish living environment is prevented from being affected by the dirt, and finally the purpose of autonomously protecting and guaranteeing the breeding environment is achieved.

Description

technical field [0001] The invention relates to the related technical field of aquaculture, in particular to a net cage for underwater culture. Background technique [0002] In order to make full use of the existing advantages of marine resources and develop aquaculture, aquaculture cages have become an indispensable equipment. [0003] The existing net cages mainly constitute the activity space of fish through leaky fishing nets, thus forming an intensive farming method, but in the actual use of the current fishing nets, it is not only difficult to provide aeration in the box to provide oxygen for fish , also because the resistance of its fishing nets is reduced under the action of strong winds, which will not only cause the fish to be squeezed by each other under the influence of strong winds, but also cause the fishing nets to rupture, resulting in leakage of the fishing nets, causing farmers Extensive property damage. Contents of the invention [0004] Aiming at the ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing net cages proposed in the background technology, the present invention provides a net cage for underwater aquaculture, which has the advantages of self-protection and guarantee of the aquaculture environment, increased oxygen content in water, and accurate feeding , which solves the technical problems raised in the above-mentioned background technology
