[0002] With the continuous growth of the global population and the increasingly deteriorating environmental problems, land resources are difficult to meet the needs of social development, and the demand for high-quality seafood by humans is increasing day by day. In order to reduce the impact of aquaculture on the inshore sea area, expand the aquaculture space, and achieve the sustainable development of the seawater aquaculture industry, it is imperative to develop the deep-sea aquaculture industry.

[0003] A solar energy device generally refers to a solar panel, which is a device that directly or indirectly converts solar radiant energy into electrical energy through the photovoltaic effect or the photochemical effect by absorbing sunlight. Compared with ordinary batteries and rechargeable batteries, solar cells are greener products that are more energy-saving and environmentally friendly.

[0004] Technical defects of deep-sea aquaculture equipment: The automation equipment and the like supporting the deep-sea fishing ground platform require continuous and stable power supply. Laying submarine cables from the land or simply using diesel generators cannot completely solve the energy supply problem of deep-sea aquaculture facilities and equipment; the deep-sea fishing ground platform has high requirements for wave resistance, the design and construction of the mooring system are difficult, the overall cost is high, and it is difficult to quickly recover the cost only by aquaculture. Summary of the Invention

[0005] In order to solve the above problems, the main object of the present invention is to provide a deep-sea intelligent cage aquaculture system based on photovoltaic power generation, which realizes deep-sea intelligent cage aquaculture based on photovoltaic power generation, stably supplies power to deep-sea ocean cages through a photovoltaic power generation unit, and can improve the convenience of berthing and fishing.

[0006] In order to achieve the above object, the present invention is realized by the following technical solutions:
