ABSTRACT:
A plant for utilizing kinetic energy inherent in the wave movement of water or heaving of the sea. The plant comprises a float unit and energy absorption apparatus connected to the unit. The absorption apparatus comprises an immersed piston built into an elongate acceleration pipe, which is open at both ends and substantially vertical, this pipe being connected to the float unit and accompanying it in the wave motion of the water.
The piston is connected to a hydraulic motor driving an electric generator.
The piston is arranged in a portion with extended cross section upwards in the acceleration pipe.
Coupled between the piston and hydraulic motor there is a hydraulic cylinder with a double-sided piston, and a rectifying hydraulic circuit for always supplying hydraulic pressure to the same side of the hydraulic motor.
A flywheel can be connected between the hydraulic motor and generator for smoothing out the action of pressure variations on the generator.
