Pipe frame type lifting deepwater culture net cage

Abstract

The invention discloses a pipe frame type lifting deepwater culture net cage, and solves the problems that in an existing large culture net cage, fishing is inconvenient after fishes are cultured, and the stability of a cage net frame structure is not ideal. Inner annular floating pipes are horizontally arranged at intervals, outer annular floating pipes are correspondingly connected to the outer sides of the inner annular floating pipes through pipe connecting pieces, and vertical connecting pipes are correspondingly fixed to the pipe connecting pieces between the inner annular floating pipes and the outer annular floating pipes respectively; an inner netting is fixed to the inner sides of the inner annular floating pipes, and the inner side of the inner annular floating pipe at the bottom end is connected with a plurality of bottom annular floating pipes with the diameters gradually reduced through pipe connecting pieces; and the inner annular floating pipes, the outer annular floating pipes and the bottom annular floating pipes communicate with breather pipes through communicating pipes, and at least one fish outlet net sleeve is arranged on the inner netting. The pipe frame structure formed by connecting the inner annular floating pipes, the outer annular floating pipes and the vertical connecting pipes through the pipe connecting pieces is good in stability and not prone to deformation when encountering stormy waves; and the whole culture net cage floats upwards during fish catching and is convenient in fish catching.

Description

technical field [0001] The invention relates to a fish culture tool, in particular to a pipe-frame lifting deep-water culture net cage. Background technique [0002] We know that deep-sea aquaculture cages are generally placed in open deep waters. It is a brand-new aquaculture equipment that has been developed rapidly at home and abroad in the past ten years. It breaks the disadvantages of traditional cages that can only be placed in harbors or offshore. And because the water temperature in the deep water is moderate, the stability is good, it is close to nature, the survival rate of the cultured fish is high and the scale is large, and the meat quality of the cultured fish is close to that of the wild, so the deep sea cage culture is more and more popular. However, due to the large wind and waves to be resisted by deep-sea net cages, especially in order to resist typhoon disasters at sea, it is required that the net cages must have sufficient strength to resist wind and wav...
