Description

technical field [0001] The invention belongs to the field of multi-energy combined power generation on the sea surface, and more particularly relates to a device for power supply / energy storage to offshore equipment by utilizing wave potential energy, solar energy and temperature difference energy to generate power jointly. Background technique [0002] With the construction and use of a large number of marine equipment in my country in recent years, it is difficult for deep-sea equipment to rely on land power grid systems for power supply, and the construction of offshore energy systems has gradually become an important constraint in the construction of maritime military and civilian equipment. At present, offshore energy generation can be divided into wind energy, wave energy, tidal energy, salt difference energy, solar energy and multi-energy combined power generation technology according to the type of energy utilization. A single offshore power generation technology has...

AI Technical Summary

Problems solved by technology

Single-energy power generation technology has prominent problems and obvious defects. At present, most multi-energy combined power generation technologies increase power generation at the cost of increasing costs, which does not significantly improve power generation efficiency and economy.

In addition, technologies such as tidal power generation, wind power generation, and salt difference energy generation technology are large in scale, complex in installation and layout, and high in investment costs, and are not suitable for independent power supply of small and medium-sized offshore equipment.
