Description

Technical Field

[0001] The present invention relates to the technical field of marine renewable energy utilization, and in particular to an offshore pile-based wind-solar-wave coupled power generation device based on a jacket foundation. Background Art

[0002] In recent years, the dependence of social and economic development on energy has increased day by day, and traditional fossil energy can no longer meet the needs of social and economic development. In addition, the environmental pollution and climate change problems caused by the consumption of traditional fossil energy have seriously affected the living environment and quality of life of human beings. Therefore, it is urgent to reduce dependence on traditional fossil energy and develop renewable clean energy.

[0003] Offshore wind energy, solar energy and wave energy are all renewable energy technologies that are recognized by the world as having little impact on the environment and broad development prospects. The use of offshore natural resources to extract electricity does not emit carbon dioxide, sulfur dioxide and other gases that are extremely harmful to the environment. In addition, my country's vast sea areas also contain extremely huge wind energy, solar energy and wave energy. The diameter of offshore wind turbines is usually between 30m and 170m, and the spacing is 5 to 15 wind turbine diameters, resulting in a large area of ​​sea between wind turbines, which provides favorable conditions for the integration of offshore photovoltaic systems. Wind-solar combined power generation can maximize the renewable energy production capacity per unit area, reduce the cost of electricity while sharing the power base, and increase the output of offshore wind power of the same scale by 40%. In addition, due to the influence of seasonal changes and weather changes, both wind and solar energy have the defect of unstable power generation. However, wind energy and solar energy have natural complementary advantages, that is, strong light during the day and strong wind at night, strong light and weak wind in summer, and strong wind and weak light in winter and spring. Wind-solar complementarity makes full use of the alternation of wind and solar energy resources and is a new energy system with high cost performance. In addition, the combination of wave energy devices and wind turbine platforms can achieve both infrastructure sharing and energy complementary utilization, thereby achieving the goal of reducing costs and increasing efficiency. Therefore, developing offshore wind-solar-wave coupled power generation technology, solving key technical problems of offshore wind-solar-wave coupled power generation and ultimately achieving industrial development are of great significance to my country's future.

[0004] At present, the technology for coupling offshore wind energy, solar energy and wave energy mainly focuses on offshore wind-solar coupling and offshore wind-wave coupling power generation technology. The existing development of offshore wind energy, solar energy and wave energy lacks a device structure that can achieve simultaneous coupling and utilization of the three energies of wind, solar energy and wave energy for power generation, and it is also impossible to reasonably and effectively couple the three energies for power generation in the same field, which has become a technical bottleneck restricting the development of research related to marine renewable clean energy in my country.

[0005] In order to make up for the deficiencies of the prior art, the present invention provides an offshore pile-based wind-solar-wave coupled power generation device based on a conductor frame foundation.

[0039] When the device is in use, wind power is generated through the horizontal axis wind turbine 3, and the sea breeze drives each blade 303 to rotate, thereby driving the horizontal axis wind turbine 3 to generate electricity. Solar energy relies on floating photovoltaic power generation modules. According to needs, a corresponding number of floating power generation components can be selected and fixed in pairs with hinges. The light energy generated by solar energy is used to generate electricity through the photovoltaic power generation system 5. In addition, the photovoltaic panels 501 of the photovoltaic power generation system 5 can be adjusted accordingly according to the angle of sunlight to increase the irradiation angle of sunlight and obtain more solar energy.

When wave energy is used for power generation, the waves drive the float 23 floating on the sea surface to float up and down. As the float 23 floats, it drives the swing arm 22 to flip along the hinge position of the inner hinge seat 21. When the swing arm 22 moves up and down, it drives the hydraulic cylinder 26 to make reciprocating motion through the hydraulic cylinder hinge seat 28, so that the hydraulic oil in the hydraulic cylinder 26 is continuously sucked in the oil tank 29, so that the hydraulic motor 30 is continuously rotated, and the generator 31 is continuously generating electricity.
