Apparatus converting ocean wave energy

摘要

Apparatus converting ocean wave motion energy to electric power is comprised of a combination of prior art devices floating on catamaran-type pontoons (40) fastened by cables (44) to the floor of a body of water. An auger-type helical member (20) rotates around a horizontal shaft-pipe axle (70) at the water's surface by the force of incoming waves near shore. A multiple-blade impeller (30), with radial blades perpendicular to the shaft-pipe axle, is placed at various points on the same shaft-pipe axle simultaneously with the helical impeller. The blades of the multiple-blade impeller (32a & b) are shaped for maximum conversion of wave energy to boost the rotation of the shaft-pipe axle in high volume, low pressure waves. The common shaft-pipe axle is coupled to gear devices (50) to drive energy conversion devices (50) such as electrical generators.
