Wave energy supply system for ship - uses relative movement between coupled floats to drive generator shaft coupled to freewheel mechanism

摘要

The system uses wave energy to operate the drive and ancillary supplies onboard a ship. It comprises at least two floats (1, 2), connected to allow them to pivot and/or move vertically relative to one another. This movement is transferred via a cog mechanism to a rotary drive shaft (10), which is in turn coupled via a freewheel coupling (11), operable in either direction, to a generator (12). A number of secondary floats may each be coupled with a main central float, with the movement of each secondary float used to obtain rotation of a respective drive shaft. The central main float may comprise the hull of the ship.
