Hydraulic lifting and rotatable marine fish culture net cage and use method thereof

Abstract

The invention discloses a hydraulically lifting and rotatable marine fish culture net cage and a use method thereof. The hydraulically lifting and rotatable marine fish culture net cage comprises a floating body, a culture net cage body, a hydraulic lifting assembly and a rotating assembly, the floating body floats on the water surface, the hydraulic lifting assembly is arranged on the floating body and connected with the culture net cage body, the culture net cage body realize ascending / descending motions relative to the floating body through the hydraulic lifting assembly, the surface of the culture net cage body is provided with a fishing net in a coated mode, and the rotating assembly is arranged on the floating body and is connected with the culture net cage body, so that the culture net cage body is in a descending state to realize rotary net sunning of the culture net cage body. According to the hydraulic lifting and rotatable marine fish culture net cage and use method thereof, the net cage has the lifting and rotating functions, the net cage lifting function can reduce net cage draught and solve the problems of net cage hauling, docking maintenance and adult fish capturing; and the net cage rotating function can achieve net sunning to remove marine organisms and solve the problem that the fishing net is frequently replaced due to marine organism attachment.

Description

technical field [0001] The present invention relates to marine culture equipment, more specifically, to a hydraulic lifting, rotatable sea fish culture net cage and its use 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 ...

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.
