Seawater culture net cage of improved structure

Abstract

The invention provides a seawater culture net cage of an improved structure, and belongs to the technical field of culture equipment. The seawater culture net cage of the improved structure comprises an upper floating body, a base plate, four stand columns, a cleaning pipe and a water pump. A net body is arranged between the upper floating body and the base plate. Each stand column is vertically provided with a guiding rod. The edge of the upper floating body is provided with four first guiding sleeves, the first guiding sleeves are arranged on the corresponding guiding rods in a sliding mode. An outer net body is arranged on the periphery of the outer sides of the four stand columns. A plurality of first nozzles and a plurality of second nozzles are arranged on the cleaning pipe. The first nozzles are right opposite to the net body, the second nozzles are right opposite to the outer net body, the water pump is arranged at the upper end of one stand column, the water pump is communicated with the cleaning pipe through a host, and each stand column is provided with a driving mechanism. The seawater culture net cage has the advantages that the net bodies can be automatically cleaned, and garbage in sea is prevented from being gathered around the net bodies.

Description

technical field [0001] The invention belongs to the technical field of aquaculture equipment and relates to a seawater aquaculture cage with an improved structure. 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 affects the lack of oxygen in the fish cultured in the mariculture cage. In addition, the long-term atta...

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, thus making the seawater The oxygen content in the water body in the aquaculture net cage is reduced, which affects the lack of oxygen in the fish cultured in the mariculture net cage. In addition, the long-term attachment of aquatic organisms to the net will affect the service life of the net, so it is necessary to clean the net regularly. At present, net cleaning is mainly carried out manually, which has low work efficiency and high labor intensity.

[0005] In addition, there are a lot of marine debris floating in the ocean. These marine debris will drift around under the action of ocean currents and waves, and often gather around the cages, affecting 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
