Oxygenating device for deep sea aquaculture net cage

Abstract

The invention relates to the technical field of marine aquaculture equipment, and discloses an oxygenating device for a deep sea aquaculture net cage. The device comprises a net frame, wherein the outer portion of the net frame is fixedly sleeved with a pedal, the bottom of the net frame is fixedly provided with an annular plate, the inner wall of the annular plate is fixedly provided with a supporting rod, the other end of the supporting rod is fixedly provided with a supporting disk, the bottom face of the supporting disk is fixedly provided with a fixing pipe, and the bottom end of the fixing pipe is movably sleeved with a driving box. Through the guide action of a guide plate in flowing seawater, the orientation of a water inlet is always opposite to the direction of seawater flowing,so that the flowing seawater enters the inner portion of the driving box through the water inlet and a water inlet hole and pushes a driving water wheel to rotate clockwise to provide continuous powerfor the oxygenating device, thereby saving energy and protecting the environment, reducing the cost of the net cage breeding marine organisms, reducing the labor amount of workers, and increasing thepractical value of the deep sea aquaculture net cage.

Description

technical field [0001] The invention relates to the technical field of marine aquaculture equipment, in particular to an aeration device for deep-sea aquaculture cages. Background technique [0002] In order to reduce the aquaculture density in shallow sea areas and improve the water quality of seawater in shallow sea areas, people use frames, mesh bags and fixing devices to assemble deep-sea aquaculture cages. Carry out marine organism breeding, and equipped with an aeration device to increase the amount of dissolved oxygen in seawater in the cage, so as to increase the breeding density of marine organisms in the cage. But, existing deep-sea culture net cage still has the following deficiencies with the aeration device: [0003] 1. The existing aeration devices for deep-sea culture cages use fuel oil or electricity as the power source, which consumes a lot of energy and increases the cost of marine organism culture. [0004] 2. The existing deep-sea aquaculture net cages ...

AI Technical Summary

Problems solved by technology

[0003] 1. Existing aeration devices for deep-sea aquaculture cages use fuel oil or electricity as power energy, which consumes a lot of energy and increases the cost of marine biological aquaculture

[0004] 2. The power energy stored in the existing aeration device for deep-sea aquaculture cages is limited, and it is necessary to replenish the power energy for the aeration device in time, which increases the workload of the staff and reduces the practical value of the deep-sea aquaculture cage

[0005] 3. During the use of the aeration device for deep-sea aquaculture cages, the power energy supply is not timely, which makes the aeration device stop due to lack of power energy. At the same time, the aeration device needs to be replaced Closed for a period of time, both cases will lead to hypoxia of marine organisms in the cage. With the prolongation of the hypoxia time of marine organisms in the cage, the number of marine organisms dying due to hypoxia in the cage will gradually increase, resulting in The yield of marine life is very low
