ABSTRACT:
A wave power apparatus at least a part of which is permanently fixed to the sea floor or to ground, i.e. such as to a breakwater, a mole, a pier, a jetty, a cliff or an oil rig. The wave power apparatus (302) includes a plurality of rotationally supported arms (322), each of which carries a float (324) at its free end, so that a translational movement of the float caused by a wave results in rotation of the arm. The apparatus comprises power conversion means for converting power transmitted from the wave to the arms into electric power, e.g. a hydraulic system, in which a hydraulic fluid is displaced by the movement of the arms (322) to drive one or more hydraulic motors. The plurality of apparatus is arranged in a row such that a wave passing the row of arms causes the arms to successively pivot with a mutual phase shift. Thereby, an even power output may be achieved, and the need for frequency converters may be reduced or eliminated. Preferably, each arm is connected to a hydraulic cylinder (328) of the hydraulic system, whereby a plurality of arms feed hydraulic medium into the hydraulic motor or motors through common hydraulic conduits.
