Abstract

The invention discloses a single pile platform-based vertical axial wind turbine-bidirectional wave energy device-tidal current energy device integration structure, and belongs to the field of ocean energy utilization. The single pile platform-based vertical axial wind turbine-bidirectional wave energy device-tidal current energy device integration structure comprises a vertical axial wind turbine, a bidirectional wave energy power generation device, a bidirectional hydraulic power generation system located in the bidirectional wave energy power generation device, a tower structure, a single pile supporting platform structure, a tidal current energy power generation device and an assorted power transmission system. The integration structure obtains wind energy by using the vertical axial wind turbine at the upper part, obtains wave energy by using the vertical and horizontal bidirectional wave energy power generation devices arranged on the water level of the tower structure, and obtains tidal current energy by using the tidal current energy power generation device arranged on the underwater single pile supporting platform structure. The bidirectional wave energy device can simultaneously make use of motions relatively vertical and horizontal to the tower structure to drive a hydraulic transmission system to generate power, thus effectively improving the utilization efficiencyof wave energy.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, and in particular relates to an integrated structure based on a single pile platform vertical axis wind turbine-two-way wave energy device-tidal current energy device. Background technique [0002] Offshore wind energy, wave energy and tidal current energy are all clean and renewable marine energy sources. Wind power generators can be used to convert wind power into electrical energy, wave power can be used to convert wave energy into electrical energy, and tidal current power can be used to convert tidal current energy into electrical energy. . The exploitable offshore wind energy resources in the eastern coast of my country not only have huge resource potential, but also have good market conditions for development and utilization, and are closer to China's economic center. Offshore wind energy development has the advantages of saving precious land resources, more stable wind power, larg...

Problems solved by technology

[0004] The deficiencies of the prior art are: the energy conversion rate of the wave power generation device and the tidal current power generation device is low, the unit power generation cost is high, and there is a lack of a power generation device structural system that simultaneously utilizes two-way and multi-way relative motion to obtain wave energy

At present, there is still a lack of a comprehensive marine energy development structure system that integrates vertical axis wind turbines, multi-directional wave energy generation devices, and tidal current energy generation devices.
