Multipurpose mariculture equipment based on net cage

Abstract

The invention belongs to the technical field of mariculture and particularly provides multipurpose mariculture equipment based on a net cage. The equipment comprises a buoyancy tank, the net cage, a motor, a rotating shaft, stirring units, a fishing unit, an inner blocking net, an outer blocking net, a take-up wheel, oxygen blowing bags and support rods, wherein the net cage is immersed in seawater; the net cage is cylindrical and open at the top, a group of water via holes are formed in the side wall and the bottom of the net cage and used for exchanging seawater; a waterproof box is arrangedin the center of the bottom of the net cage; a speed-adjustable motor capable of rotating forward and reversely is arranged in the waterproof box; a rotating shaft is rotationally connected with theposition, corresponding to an output shaft of the motor, in the net cage; the output shaft of the motor is fixedly connected with the rotating shaft. By means of rotation of the motor and driving of the rotating shaft, the take-up wheel, stay cords and the support rods, the support rods are driven to extrude the oxygen blowing bags, oxygen in the oxygen blowing bags are extruded out, the oxygen content of seawater in the net cage is increased, normal growth of mariculture products is guaranteed, breeding density of the net cage is increased, and the breeding cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mariculture, in particular to multipurpose mariculture equipment based on net cages. Background technique [0002] With the improvement of people's living standards, the demand for seafood is increasing. It is difficult for traditional fishing operations to guarantee the normal supply of seafood. , Quick results and other characteristics, so in just a few decades, it has flourished all over the country. [0003] At the same time, cage culture has also produced many environmental problems. In order to maximize the output rate, domestic enterprises often increase the production by increasing the breeding density. At the same time, the seafood farming areas are all located in the offshore, and the seawater has insufficient fluidity. Increasing the density of aquatic products and increasing the oxygen content of the breeding water has become an urgent problem to be solved. At the same time, the aquaculture ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, solve the problem that the oxygen content of the breeding water is too low due to the increase in the density of aquatic products, and at the same time, the aquaculture wastewater will cause the environment of the aquaculture waters to deteriorate, and the seafood will die during the breeding process. If it is not cleaned up in time, the dead seafood will rot. After deterioration, the germs increase, which seriously endangers the safety of aquaculture. The present invention proposes a multi-purpose marine aquaculture equipment based on net cages.
