Description

technical field [0001] The invention relates to a power generation device based on rolling motion, which can be installed in rolling wave power generation equipment or rolling breakwater, and belongs to the new energy field of using ocean energy to generate electricity. Background technique [0002] In 1974, engineer Salter invented a rolling wave energy conversion device. The design of the device is rigorous, and the cross-sectional profile is asymmetrical. The underwater part is arc-shaped, and the device rolls around the rotation axis under the action of waves, and can intercept almost all short waves. The primary conversion efficiency of this wave energy conversion device can be close to 100% in short waves. [0003] Although the research on wave power generation has been developed for decades, there have been dozens of different power generation device designs to improve power generation efficiency. However, the existing wave generators still have the following disadva...
