Seawater aquaculture net cage capable of preventing attachment of marine organisms

Abstract

The invention belongs to the technical field of aquaculture equipment and provides a seawater aquaculture net cage capable of preventing attachment of marine organisms. The seawater aquaculture net cage with an automatic netting cleaning function comprises an upper floater, a bottom plate, four vertical columns, a bubble pipe and a high-pressure air pump. Netting is arranged between the upper floater and the bottom plate, the four vertical columns are arranged at four outer corners of the upper floater respectively, each vertical column is provided with a guide rod, and four first guide sleeves are arranged at the edge of the upper floater and slidably arranged on the corresponding guide rods. Four second guide sleeves are arranged at the edge of the bottom plate and slidably arranged on the corresponding guide rods, outer netting externally surrounds the four vertical columns, the bubble pipe is spirally arranged outside the netting, the lower end of the bubble pipe is closed while the upper end of the bubble pipe is communicated with an air outlet of the high-pressure air pump, and the high-pressure air pump is arranged at the upper end of one of the vertical columns. The seawater aquaculture net cage has advantages of high capturing efficiency, available for netting cleaning, prevention of marine organism attachment on the netting, and the like.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture equipment, and relates to a marine aquaculture net cage which can prevent the attachment of marine organisms. Background technique [0002] Marine aquaculture cages are the main equipment for fish farming in the sea, and they have been widely used. [0003] Marine aquaculture cages generally include an upper floating body, a cage frame, and a net set on the cage frame and the upper floating body. [0004] Because mariculture cages are located in the water body for a long time, the aquatic organisms in the water body will slowly attach to the nets of the mariculture cages, thereby blocking the meshes and reducing the fluidity of the water inside and outside the mariculture cages, thus making the seawater The oxygen content of the water body in the culture cage is reduced, which is likely to cause hypoxia for the fish cultured in the marine culture cage. In addition, the long-term attachment of aquatic ...

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
