  • Patent number: 7694513
    Abstract: A wave power apparatus includes a plurality of rotationally supported arms, each of which carries a float (124) 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 to drive one or more hydraulic motors. The plurality of are 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 of the hydraulic system, whereby a plurality of arms feed hydraulic medium into the hydraulic motor or motors through common hydraulic conduits.

  • Patent number: 7579704
    Abstract: A wave power apparatus includes at least one rotationally supported arm (122) which carries a float (124) at its free end, so that a translational movement of the float caused by a wave results in rotation of the arm (122). 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 medium is displaced by the movement of the arm, the hydraulic system being coupled to an electric generator. The apparatus comprises a hydraulic lifting system for lifting the float out of the ocean and for locking the float in an upper position above the ocean surface, e.g. during extreme sea wave conditions, such as storm. The lifting system may comprise at least one pump for pumping hydraulic cylinders for lifting the arm out of the ocean.

  • Patent number: 6925800
    Abstract: The wave force machine as such is constructed in such a way that it is capable of utilizing the upward force from the waves with (FIG. 1) the force from float (1) and rocker arm (3) via rocker arm pipe (4), wherein 1 or more lock bearings are provided, which transfer the upward force causing the driving force shaft (8) to rotate in the same direction. On each driving force shaft (8) may be one after the other of mounted float, rocker arm and rocker arm pipe with lock bearings after the other, and several driving force shafts (FIG. 6) (6,7,8 and 9) may be interconnected both horizontally and vertically to toothed wheel (1, 2, 3, 10, 11, 12, 13 and 14) shown here with 4 driving force shafts, but in principle any number of shafts may be interconnected. The total force from the driving force shafts may be brought to gearbox and electric generator and used in electricity production. 3 wave force machines may e.g. be interconnected to form e.g.
