Wind turbine and multi-floater wave energy power generation device integrated semi-submersible platform structure

Abstract

The invention belongs to the field of ocean energy utilization, and provides a wind turbine and multi-floater wave energy power generation device integrated semi-submersible platform structure. The platform structure comprises a wind turbine, a tower structure, a semi-submersible platform, an anchor chain, a floater wave energy power generation device and a matched power transmission system. The floater wave energy power generation devices are symmetrically arranged on the water surface of the auxiliary stand column on the outer side of the semi-submersible type platform, and the floater structure conducts vertical relative movement on the outer side face of the auxiliary stand column structure of the platform through the pulley-sliding way device to drive the two-way hydraulic power generation system to achieve wave energy power generation. By sharing the semi-submersible platform structure and the power transmission system, the construction cost of independently using an offshore wind turbine and a wave energy power generation device is reduced; the floater wave energy power generation device can not only provide wave energy generating capacity, but also effectively reduce the rolling and pitching motion response of the semi-submersible platform. The platform structure can be widely applied to development of deepwater wind energy-wave energy resources.

Description

technical field [0001] The invention relates to the field of ocean energy utilization, in particular to a semi-submersible platform structure integrated with a wind turbine and a multi-floor wave energy generating device. Background technique [0002] Offshore wind energy and wave energy are both clean and renewable ocean energy, and they can all be attributed to solar energy in essence. Because of the natural correlation between wind and waves, wind-rich waters are also rich in wave energy resources. The exploitable offshore wind energy resources along the east coast of my country are very rich, not only has huge resource potential, but also has good market conditions for development and utilization, and is closer to China's economic center. With the gradual expansion of offshore wind farms to deep waters, the supporting platform structure has gradually developed from a fixed foundation to a floating structure system. At present, many floating offshore wind power demonstr...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the existing technology are: with the gradual development of the single unit capacity of offshore wind turbines from 5MW to 10MW or even 20MW, this poses a great challenge to the optimal design of the structural system of the floating offshore wind turbine support platform; The conversion rate is low, and the unit power generation cost is high. It is necessary to explore the integrated application with related marine structures to achieve cost optimization.

At present, there is a lack of a comprehensive marine energy development structure system that integrates semi-submersible wind turbines and multi-floor wave energy generation devices.
