    摘要: The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

    摘要: A means for improving the motion stability of a floating, semi-submerged, or submerged body used in, multi-capture-mode wave energy converters (WECs) having two or more bodies, against wave-induced heave, surge, and pitching forces, while reducing the size, mass and cost of such bodies or bases, thus improving the relative motion and hence capture efficiency of such WECs over a broad spectrum of wave periods and wave heights. Stabilizing counter moments against wave-induced motion are substituted by strategic placement of drag plates or planes entraining seawater mass or water-filled cavities within, or attached to, the bases and/or at least one tensioned seabed-affixed cable. The base or reaction-body stabilizing means is disclosed in a two-body multi-capture-mode, deep-water, surface-deployed, wave-terminator-type WEC to concurrently increase wave energy capture efficiency and reduce the volume, mass, and capital cost of the WEC's stabilized reaction body or base.

    摘要: A wave activated electric power generating system is durable even if exposed to a rainstorm, extremely simple in structure and highly efficient. A motion transfer medium rendering the rotary part of an electric generator less liable to produce slipping and a rotation transform member adapted to rotate while fitting with the motion transfer medium in movement are also provided. The system includes a buoy floating on the sea or lake so as to move up and down with the waves, and an underwater motion restrainer suspended underwater by water resistance, or submerged by its own weight on the sea or lake floor. Vertical movement of the buoy relative to the underwater motion restrainer is converted and transferred by the motion transfer medium in the form of an elongate rope vertically moving under the weight of an element to operate the rotary electric generator securely connected to the buoy.

    摘要: The generator comprises: at least one energy capturing float (2) which is movable in response to wave motion; a reaction member (1) to be positioned below the energy capturing float; connecting lines (4a, 4b,4c,4d) for connecting the at least one energy capturing float to the reaction member and defining a spacing (D3) between the energy capturing float and the reaction member; energy converters (3a,3b,3c,3d) for converting relative movement between the reaction member and at least one respective energy capturing float to useful energy. The generator includes depth setting means such as adjustable lines (8a,8b) connected to auxiliary floats (7a,7b) or adjustable mooring lines (9a,9b 9c,9d) securing the reaction member to the sea bed B for setting the depth (D1) of the reaction member in the sea.

    摘要: A shutter valve for alternatingly allowing and stopping a high pressure water flow, such as in a device for generating energy from sea waves, comprising a tube section (201) having a rectangular cross section, wherein a multitude of vanes (202) are rotatably mounted in the tube section (201), wherein the vanes have a relatively large rectangular longitudinal cross section in a first direction, a relatively flat rectangular longitudinal cross section in a second direction perpendicular to said first direction, and a generally flat cross section in a third direction perpendicular to said first and second directions, said third direction being the axis of the vane (202), wherein the circumferential wall around the axis of each vane forms a closed water impermeable surface, wherein the axes of said multitude of vanes all extend in a parallel manner, characterized in that the distances between the axes of adjacent vanes are approximately half the distance between the outer tips of the vanes, seen in the cross section in said third direction, such that when the vanes are rotated to the closed position the lower half of the front surfaces and upper half of the back surfaces of all vanes form a single closed front surface and a single closed back surface, each in substantially a single flat plane perpendicular to the flow axis of the valve, said surfaces closing the opening of said tube section, and the other half of said front surfaces and the other half of said back surfaces of said vanes rest against each other.
