[0002] Ocean power generation uses clean energy, does not produce pollutants, and has little impact on the environment. At the same time, ocean energy is sustainable and will not be exhausted, so ocean power generation helps reduce dependence on traditional fossil fuels, reduce greenhouse gas emissions, and respond to global climate change. Ocean power generation devices mainly generate electricity through wave energy, wind energy, and light.

[0003] However, in actual use, when solar panels are used to collect sunlight for power generation, most solar panels are fixed, which makes it inconvenient to adjust the retraction and deployment in real time according to environmental conditions. The wind load at sea at night can easily affect the device and affect the service life of the device. Moreover, when wave energy is used for power generation, the energy of vertical fluctuations is mostly captured, and the energy of waves in multiple directions such as swaying, rolling, pitching and rolling cannot be effectively utilized. This single energy conversion method limits the overall energy capture capability of the device, resulting in the energy conversion efficiency that needs to be further improved. Therefore, a power generation device for the ocean and a method for using the same are proposed. Summary of the invention

[0065] In this embodiment, when power generation is performed, the device floats on the sea surface through multiple floating bodies 15. At this time, the wind force on the sea surface can act on the fan blades 6, so that the fan blades 6 drive the cross chuck 3 to rotate through the limiter 5 and the square rod 4.
