Raising rotatable sea fish breeding net cage and use method thereof

Abstract

The invention discloses a raising rotatable sea fish breeding net cage and a use method thereof. The raising rotatable sea fish breeding net cage comprises structure floating bodies, a breeding net cage body, a lifting mechanism and a rotating mechanism, wherein the structure floating bodies float on a water surface, and a hanger is arranged on each structure floating body; the lifting mechanism is arranged on the hangers, and is connected with the breeding net cage body; the breeding net cage body realizes rising/falling movement relative to the structure floating bodies through the lifting mechanism; a fishing net is used for coating the surface of the breeding net cage body; and the rotating mechanism is arranged on the structure floating bodies and is connected with the breeding net cage body so that when the breeding net cage body is in a falling state, rotary net drying of the breeding net cage body is realized. According to the raising rotatable sea fish breeding net cage disclosed by the invention, a net cage can have the functions of lifting and rotating, so that draft of the net cage is reduced, the difficult problems of hauling and docking for repair and maintenance of the net cage, and adult fish capturing can be solved, the difficult problem of frequent replacement of fishing nets caused by marine organism adhering is solved, and breakage of the fishing nets is convenient to examine.

Description

technical field [0001] The present invention relates to sea culture equipment, more specifically, to a lifting and rotatable sea fish culture net cage and its usage method. Background technique [0002] In order to increase the effective breeding water body in the existing marine fish breeding cages, most of the volume of the cages is below the water surface, so that the bottom of the marine fish breeding cages is far away from the water surface (that is, the draft is very large). The haulage after the construction of the aquaculture cages, the capture of marine fish after cultivation, and the docking and maintenance of the marine fish aquaculture cages in the later stage of use all face difficulties. At the same time, marine organisms grow vigorously in summer, and fishing nets submerged in seawater are prone to growth of marine organisms. Traditional aquaculture cages face the problems of frequent replacement of fishing nets and failure to detect damage to fishing nets in ...

AI Technical Summary

Problems solved by technology

[0002]In order to increase the effective culture water body in the existing marine fish culture cages, most of the volume of the cages is below the water surface, so that the bottom of the marine fish culture cages is far away from the water surface Large (that is, the draft is very large), limited by the water depth of the channel, the haulage after the completion of the construction of the marine fish culture cage, the capture of the marine fish after cultivation, and the docking maintenance of the marine fish culture cage after use are all facing difficulties

At the same time, marine organisms grow vigorously in summer, and fishing nets immersed in seawater are very easy to grow marine organisms. Traditional aquaculture cages face the problems of frequent replacement of fishing nets and failure to detect fishing net damage in time.
