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 th

Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] like Figure 1 to Figure 3 Shown, a kind of net cage for mariculture comprises a rectangular upper floating body 2, a base plate 3, a column 1, a cleaning pipe 13 and a water pump 21, and the upper floating body 2 is provided with a net cage opening 2b, and the upper floating body 2 and A netting 9 is arranged between the base plates 3, and the base plate 3, the netting 9 and the upper floating body 2 form a breeding area, and the upper floating body 2 can float on the sea surface, that is, the buoyancy of the upper floating body 2 is greater than that of the upper floating body 2 , the gravity of bottom plate 3 and net clothing 9;

[0030] There are four uprights 1 and they are located at four corners on the outsi...

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...
