Marine aquaculture net cage

Abstract

The invention provides a marine aquaculture net cage, and belongs to the technical field of aquaculture equipment. The marine aquaculture net cage comprises a rectangular upper floating body, a bottom plate, four upright columns, cleaning pipes and a water pump. A net cage opening is formed in the upper floating body, netting is arranged between the upper floating body and the bottom plate, the four upright columns are positioned at four corners of the outer side of the upper floating body, a guide rod is vertically arranged on each upright column, four guide sleeves are arranged at the edge of the upper floating body, are in one-to-one correspondence to the guide rods and are slidably arranged on the corresponding guide rods, the rectangular cleaning pipes are arranged on the outer side of the netting in an enclosed manner, a plurality of spray nozzles are arranged on the cleaning pipes and directly face the netting, the water pump is arranged on one of the upright columns and is communicated with the cleaning pipes via hoses, and a driving mechanism for driving the corresponding cleaning pipe to move up and down along the vertical direction is arranged on each upright column. The marine aquaculture net cage has the advantages that the netting can be automatically cleaned, marine organisms can be prevented from being attached onto the netting, and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment, and relates to a net cage for seawater aquaculture. Background technique [0002] Mariculture cages are the main equipment for sea-related fish farming and have been widely used at present. [0003] Mariculture net cages generally include an upper floating body, a net cage frame and net clothing arranged on the net cage frame and the upper floating body. [0004] Because the mariculture cages are located in the water body for a long time, the aquatic organisms in the water body will slowly attach to the netting of the mariculture cages, thereby blocking the mesh holes and reducing the fluidity of the water body inside and outside the mariculture cages, thereby making the seawater The oxygen content in the water body in the aquaculture net cage is reduced, which will easily cause the fish cultured in the mariculture cage to be hypoxic. In addition, the long-term attachment of aquati...

Problems solved by technology

[0004] Because the mariculture cages are located in the water body for a long time, the aquatic organisms in the water body will slowly attach to the netting of the mariculture cages, thereby blocking the mesh holes and reducing the fluidity of the water body inside and outside the mariculture cages, thereby making the seawater The oxygen content in the water body in the aquaculture net cage is reduced, which will easily cause the fish cultured in the mariculture cage to be hypoxic. In addition, the long-term attachment of aquatic organisms to the net will affect the service life of the net, so the net needs to be cleaned regularly However, at present, net cleaning is mainly carried out manually, which has low work efficiency and high labor intensity.

[0005] In addition, there are also a lot of garbage and impurities floating in the ocean, which tend to gather around the cages and affect the survival of fish in the cages

[0006] Secondly, because of the existence of the net cage frame, when catching seafood in the sea culture net cage, it is necessary to use a large fish suction pump to fish, the fish at the bottom of the net cage are difficult to catch, and the fishing cost is relatively high
