Fish protection and power generation device for deep-sea aquaculture net cage

Abstract

The invention provides a fish protection and power generation device for a deep-sea aquaculture net cage. The device mainly comprises a bearing frame, a large gear, a small gear, a gearbox, a power generator, a water through hole and a protection cabin. The device is installed in the deep sea net cage, when the net cage is affected by large storm waves or even typhoons, the device can greatly reduce impact of water flow on cultured fishes in the deep sea net cage, a safe inhabitation space is provided for the fishes, and the situation that the fishes consume too much energy due to long-time reverse flow swimming, and normal growth of the fishes is affected is avoided; the growth cycle is prolonged, and the injury rate and death rate of cultured fishes are reduced; and the water flow impact energy can be utilized to generate electricity while the fishes are protected, the generated electric energy can be supplied to other equipment of the deep sea net cage for use, the self-sufficient capacity of the deep sea net cage is greatly improved, and the device has high practical application value.

Description

technical field [0001] The invention belongs to the technical field of deep-sea cage culture, and in particular relates to a device for protecting fish and generating electricity in a deep-sea culture cage. Background technique [0002] With the improvement of living standards, people's demand for seafood is increasing, and the quality requirements of seafood are getting higher and higher. However, due to the country's protection of the marine environment and resources and the limitation of fishing volume, the traditional fishing industry has become saturated, so the development of aquaculture has become an inevitable trend. [0003] The deep-sea cage is a kind of cage for aquaculture fish that can be used in deep sea areas (the depth of the sea surface is 50-70 meters). There is a large space inside the cage, so the cultured fish has a wide range of activities and habitats; and The water body in the net cage is large, and the habitat space of fish is closer to the natural ...

AI Technical Summary

Problems solved by technology

[0006] Because the deeper the depth below the sea surface, the less affected by the surge, so one of the existing deep-sea cages to avoid the impact of large waves and even typhoons is to dive the deep-sea cages to a certain depth below the sea level to reduce the surge, but this method needs to consume a lot of energy to achieve, and because the size of the deep-sea cage is very large, it is also difficult to control the cage to ascend and dive. Therefore, this method The implementation cost is high and difficult
