Lift-type aquaculture net cage

Abstract

The invention belongs to the technical field of aquaculture net cages, in particular to a lift-type aquaculture net cage. The lift-type aquaculture net cage comprises two floating pipes (1) and a floating pipe support (2); the floating pipes (1) are connected together through the floating pipe support (2). The lift-type aquaculture net cage is characterized by also comprising a plurality of vertical rigid hanging beams (3), a plurality of horizontal rigid hanging beams (4) and a gravity regulating device (5); the top ends of the vertical rigid hanging beams (3) are connected onto the floating pipe support (2), and the bottom ends of the adjacent vertical rigid hanging beams (3) are respectively connected with two ends of the corresponding horizontal rigid hanging beam (4); the gravity regulating device (5) is connected with the bottom ends of the vertical rigid hanging beams (3) through underframe nylon mooring ropes (6). The lift-type aquaculture net cage provided by the invention has the advantages that the structure is simpler, the operation control system is simpler and more reliable, netting is low in deformation; lift is safe and reliable by anti-swing cloth, and the function of the net cage is more complete and humanized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture net cages, and more specifically relates to a lifting type aquaculture net cage. Background technique [0002] Cage aquaculture is an important part of the marine economy and has a broad market and development potential. The cage culture process does not require auxiliary resources, saves resources, and has the characteristics of low investment and high return. The key factor restricting deep-sea aquaculture is the anti-wind and wave ability of cages. Solving this problem will help the entire industry to advance to deep water. [0003] At present, 95% of the total number of deep-water cages in my country are gravity-type HDPE cages imported from Norway. The structure is as follows: figure 1 As shown, this kind of tubular frame gravity cage made of HDPE (high density polyethylene) material can sink to a certain depth before the typhoon hits by setting the injection / drainage pipe, so as to avo...

Problems solved by technology

[0003] At present, 95% of the total number of deep-water cages in my country are gravity-type HDPE cages imported from Norway. The structure is as follows: figure 1 As shown, this kind of tubular frame gravity cage made of HDPE (high density polyethylene) material can sink to a certain depth before the typhoon hits by setting the injection / drainage pipe, so as to avoid the wave impact of the waterline. From the practical point of view, no matter the mooring or the structure, this kind of cage is not suitable for anti-sea current, anti-wind and wave, and it does not have the ability to survive in severe situations such as typhoons.
