Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an adjustable floating frame for deep-sea cages. Background Art

[0002] Aquaculture includes traditional pond farming and cage farming. Cage farming can be carried out directly in the deep sea. Seawater can flow in and out of the cage, and no water change is required during the farming process. Compared with traditional pond farming, the farming cost can be reduced a lot, especially for marine fish. They can be directly cultured in seawater without pumping seawater into the breeding pond, and the cost has been further reduced. At the same time, with the increasing demand for marine fish, cage farming has developed rapidly, thus posing some new challenges to the structure of cage farming.

[0003] The current deep-sea cages mainly include cage frames, nets, net bags and buoyancy adjustment mechanisms, wherein the buoyancy adjustment mechanisms are used to inflate and deflate the net bags to achieve different drafts of the cage frames, thereby adjusting the depth of the cage frames underwater. The buoyancy adjustment mechanisms of existing deep-sea cages are mostly customized according to the actual structure of the cages. However, the aquaculture scales of different manufacturers are different, and the structures and sizes of the aquaculture cages used are also different. Currently, there is no adjustable floating frame that is compatible with different cages. When the dedicated floating frame of the deep-sea cage is damaged, the entire deep-sea cage is often required to be replaced, which increases the aquaculture cost and affects the normal progress of aquaculture.
