Patent ID: 7956478

Claim:
An installation comprising a wave power apparatus comprising: a plurality of arms, each of which is rotationally supported at one end by a shaft, and wherein each arm carries a float at its other end, which is opposite to the supported end, so that a translational movement of the float caused by a wave results in rotation of the arm around the shaft; and a power converter configured to convert power transmitted from the wave to the arms into electric power, the plurality of arms being arranged in a row such that a wave passing the row of arms causes the arms to successively pivot around the shaft, the arms being arranged at mutual distances, so that the passage of the wave causes the arms to pivot with a mutual phase shift, and wherein the arms and the power converter are supported by a support structure, which is permanently fixed to the sea floor or to ground, wherein each arm extends in a longitudinal direction, and wherein the support structure extends in a direction transversely to said longitudinal direction, wherein: the support structure comprises a breakwater, mole, pier, jetty, cliff, or an oil rig; each arm is individually supported by the breakwater, mole, pier, jetty, cliff, or oil rig; the arms are arranged at mutual distances along the breakwater, mole, pier, jetty, cliff, or oil rig; the power converter comprises a hydraulic driving system with a hydraulically driven motor; each arm is connected to the hydraulic driving system by at least one double-acting cylinder which causes a hydraulic medium of the hydraulic driving system to be displaced into the motor, the actuators being arranged to displace the hydraulic medium to the motor via hydraulic conduits; and the double-acting cylinder forms part of a hydraulic lifting system, so that the cylinder is controllable to lift the float out of the ocean.
