Device for extracting energy from waves
Patent
·
OSTI ID:5764042
A device is described for extracting energy from sea waves by the motion of a submerged cylinder held normal to the direction of motion of the waves by tie members at each end of the cylinder. The tie members at their other respective ends are moored to the sea bed. Changes in the load on the tie members are arranged to turn in one direction a drum drivably connected to a vane pump. A spring, or a counterweight acting on a cam-shaped pulley, is arranged to apply a biasing load to the drum in the other direction so as to produce an oscillatory movement of the drum from changes in load on the tie members and drive the pump. A hydraulic motor connected to an electric generator is driven by the pump. The drum may be situated at the moorings on the sea bed, or at the cylinder.
