Tension leg platform based vertical axis wind turbine and vertical-horizontal two-direction wave power generation integrated structure

Abstract

The invention discloses a tension leg platform based vertical axis wind turbine and vertical-horizontal two-direction wave power generation integrated structure, and belongs to the field of ocean energy utilization. The integrated structure comprises a vertical axis wind turbine, a two-direction wave power generation device, two-direction hydraulic power generation systems located in the two-direction wave power generation device, a tower structure, a tension leg platform structure and a matched power transmission system. Relative vertical motion of the two-direction wave power generation device and the tower structure drives a vertical piston (or relative horizontal motion drives a horizontal piston) to compress liquid in hydraulic cylinders, the liquid passes through first unidirectionalinflow valves (or passes through second unidirectional inflow valves in the reverse direction) to enter hydraulic motors, the hydraulic motors are driven to rotate, and therefore power generation devices are driven to generate power. In addition, tension leg structures can effectively control longitudinal shaking and transverse shaking of a floating platform, good operation of a top fan is facilitated, and huge tower bending moment loads caused by top large-mass cabin inertial motion are controlled.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, and relates to a deep-water wind energy-wave energy comprehensive utilization device, in particular to an integrated structure based on a tension leg platform vertical axis wind turbine and vertical-horizontal two-way wave energy generation. Background technique [0002] Offshore wind energy and wave energy are both clean and renewable ocean energy. Wind power generators can be used to convert wind energy into electrical energy, and wave power devices can be used to convert wave energy into electrical energy. The exploitable offshore wind energy resources in the eastern coast of my country are about 750 million kilowatts, which not only has huge resource potential, but also has good market conditions for development and utilization, and is closer to China's economic center. Offshore wind energy development has the advantages of saving precious land resources, more stable wind power, larger...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the existing technology are: the energy conversion rate of the wave 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 uses 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 and multi-directional wave energy generation devices.
