Description
Technical Field
The invention relates to the field of wave energy power generation, in particular to a wave energy power generation device of an ocean buoy.
Background
The shortage of fossil fuels and concern over environmental impact have forced society to seek alternative energy sources that have less impact on the environment, such as renewable energy sources and sustainable energy sources. Consequently, many marine countries are interested in marine energy sources, particularly wave energy. To fully utilize wave energy before development, reliable quantification of wave energy potential is needed. Countless wave forces are evaluated, including global and regional studies, such as coastal waters in the united states, coastal waters in latin america and europe, coastal waters in china, western coast bay of france, red sea on the southwestern coast of the black sea, thailand, indonesia and philippines. The theoretical wave power is estimated to be 2.11 Tera Watt (95% confidence) on a global scale and has a buffer line up to 30 nautical miles, and it is estimated that the total theoretical wave power in the U.S. coastal region is approximately 2640 Tera Watt hours/year, roughly equivalent to 65% of the U.S. annual power consumption. China is also a national ncarshore region with abundant ocean wave energy both at sea and at sea.
In recent years, China has developed various ocean energy studies. Among them, the exploitation and utilization of wave energy are the most socially concerned issues.

Viability, etc. remain the bottleneck for the development of wave energy technology.
However, the observed data are limited to specific regions and lack of representativeness. Wave simulation has been increasingly studied with the further development of wave theory and numerical techniques. For example, the SWAN model and the WAVEWATCH-1I model are adopted to estimate the overall space-time distribution of wave energy resources in offshore areas of China. Lin et al (2019) wave energy in the neighborhoods of china was evaluated based on 20 years of SWAN post-test. Zheng et al (2011) and Shi et al (2017) performed statistical analysis data on the distribution of coastal wave energy in china using re-annual analysis.
