Title: Sea or lake wave energy convertor.
Inventor: RETZLER CHRIS-HEINZ
IPC: F03B13/18
Filed: 1991-12-17
Abstract: A device for extracting energy from sea waves utilises the motion of a rotor comprising a frame (1) and a pair of parallel cylinders (2) held at or below the surface of a liquid perpendicular to the wave direction, the cylinders being caused to rotate so as to produce Magnus effect lift, resulting in a torque around the rotor axis A---A, thus causing the rotor to perform full or part rotations. The rotor is coupled to the shaft of a hydraulic pump (3), with the pump housing held steady by tie members (4) attached to the sea bed. The pump extracts energy from the rotation of the rotor, and may be adapted to pressurise water, or to pressurise a hydraulic circuit to which a hydraulic motor may be connected to turn an electrical generator. In an alternative arrangement (Fig. 3) the hydraulic pump may be interposed between two rotors linked by a compliant member and adapted to partially contrarotate, the pump being actuated by their relative oscillation. End caps (5) (Fig 2) may be applied to the ends of the cylinders to reduce losses due to fluid circulation. <IMAGE>
