AI Technical Summary

Technical Problem

Existing deep-sea aquaculture cages and nets discharge feces and feed residues directly into the seawater during the aquaculture process, causing environmental pollution and hindering long-term aquaculture.

Method used

Design a deep-sea aquaculture cage net cover, including a main net cage and a sludge collection net cage. The main net cage is used to cultivate aquatic products, and the sludge collection net cage is used to collect feces and other impurities. A 360° covering suction is achieved through a rotating component and a suction connector component. Feces, impurities and waste fall directly into the sludge collection net cage and are cleaned through a sludge suction pipe and a sewage pump.

Benefits of technology

It effectively prevents the direct discharge of feces, impurities, and waste into the sea, maintains the ocean's self-cleaning ability, reduces negative impacts on the environment, and is conducive to scientific and long-term aquaculture.

Abstract

The utility model discloses a culture cage mesh enclosure for deepwater mariculture, which comprises a main mesh cage, the bottom of the main mesh cage is fixedly connected with a sewage collection mesh cage, a shaft rod is vertically arranged in the middle of the main mesh cage and the sewage collection mesh cage, the interior of the shaft rod is of a hollow structure, and the bottom of the shaft rod is horizontally and fixedly communicated with a sewage pumping pipe. The sewage pumping pipe is horizontally attached to the bottom of the sewage collection net cage, a plurality of suction nozzles are distributed at the bottom of the sewage pumping pipe in the length direction of the sewage pumping pipe, the rotating assembly can drive the shaft rod and the sewage pumping pipe to rotate at a constant speed, and the sewage pump sucks the shaft rod and the sewage pumping pipe through the suction loose joint assembly. The rotating sewage pumping pipe can be used for pumping excrement and sewage deposited at the bottom of the sewage collection net cage in a covering manner through the suction nozzle, and discharging and cleaning, and the operation is stopped after the suction is completed; in conclusion, the deepwater aquaculture cage net cover can effectively prevent and reduce the defect that excrement, impurities and dirt are directly discharged into the sea in the aquaculture process, the ocean self-cleaning capacity is maintained, and meanwhile the negative influence on the surrounding ocean environment is greatly reduced.
