Power control mechanism for wave power generation using differential gears

Abstract

The invention provides a mooring method that allows for easy installation of floating structures regardless of whether they are in shallow waters or offshore, requires a small area of ​​sea, and utilizes this mooring method to provide an offshore wave power generation device that is highly efficient, does not flood even when subjected to tsunamis or high waves, and takes into consideration the impact on the ecosystem. [Solution] A cable connecting a weight on the seabed to a floating body, and a weight and cable for pulling the cable taut, are installed on the floating body. These cables are wound onto drums, and the two drums are connected by a mechanism so that the weight on the seabed and the weight on the floating body pull on each other. Furthermore, by incorporating differential gears, a ratchet mechanism, and a torque limiter into the mechanism connecting the drums, the floating structure is designed to prevent flooding even if the sea level rises or falls more than expected. A wave power generation device is also installed, which generates electricity from the rotation of the drums connected to the cable as the floating body rises due to buoyancy and pulls against the weight on the seabed.
