Description

technical field [0001] The invention belongs to the technical field of ocean engineering, and in particular relates to an offshore pitch and heave coupled wave energy-wind energy integrated power generation device. Background technique [0002] In today's society, non-renewable resources are decreasing day by day, traditional energy sources are becoming increasingly exhausted, and environmental protection is getting more and more attention, which is becoming more and more important for the development and utilization of new energy sources. The ocean area accounts for more than 70% of the total area of ​​the earth, so researchers have begun to consider how to make full use of ocean resources. There are many kinds of renewable energy in the sea, such as: wind energy, solar energy, ocean current energy, tidal energy, wave energy etc. Researchers have matured in the research and development of wind and solar power generation technologies, but there are still many technical diff...
