060505000 | Having relatively movable working members | 11 |
20080295510 | Power Generating Apparatus - Power generating apparatus includes a float mounted on a support pivotally mounted to a base and secured to a beam extending rearwardly of the base to a vertically extending elongated structure carrying a pair of vertically movable gear racks in guideways. Each rack is engaged by a gear wheel driven by movement of the racks and a one-way drive arrangement connects each gear wheel to an output shaft. Driving weights are secured to each rack to drive the racks in opposite directions under the action of gravity forces acting on the weights, thus causing the output shaft to rotate in a given direction. The free end of the beam is connected to a cross-arm vertically moveable on a guide on the elongate structure, the cross-arm having a motion transmitting arrangement to raise each weight during vertical movement of the cross-arm resulting from movement of the float. | 12-04-2008 |
20100175373 | Stable Power-Output Device with a Linear Long-Shaft Driven by Wave - This invention relates to a stable power-output device driven by waves, the power-output device consists of buoys, and a scaffold with buoys, guiding tracks and rotating shafts installed. The scaffold floats on the wave, roller wheels are installed at two sides of the buoys, with each two of the roller wheels are sandwiched between the related guiding track and the related side of each buoy so that the roller wheels and the guiding tracks can work together. Guiding devices are installed on top of the buoys; rotating shafts are connected to the guiding devices and float horizontally on the waves. Ratchets are installed on the short shafts; they are in contact with the guiding devices. A shaft connector is adapted to connect each two of the rotating shafts together and form a long shaft. | 07-15-2010 |

20110162357 | ENERGY CONVERTER - A wave energy converter for extracting energy from waves in a body of liquid. The converter comprising an endless spine, the spine including a plurality of spine sections ( | 07-07-2011 |
20120090313 | Device for floating wave power plant - The present invention pertains to a device of a floating wave power plant. More precisely, the invention pertains to a submerged frame structure with an attached ballast body as an element in a floating wave power plant. The frame structure and thereby the wave power plant is preferably anchored to the sea bottom. The wave power plant comprise several pumping cylinders ( | 04-19-2012 |
20130031897 | Wave Power Plant - A wave power plant includes a platform and at least one coupling member. The at least one coupling member is mounted in such a way as to perform an orbital movement which has a predetermined direction of movement and from which a torque usable for energy conversion can be tapped. A torque compensation device is provided which is designed to essentially compensate or neutralize a reactive torque generated by tapping the usable torque. | 02-07-2013 |
20130067903 | Wave Energy Conversion Device - A wave energy conversion device including a first pontoon configured to respond to an incident wave by operating in at least a first mode of motion and a second pontoon movably attached to the first pontoon by attachment means and configured to respond to an incident wave by operating in at least one mode of motion different from the first mode of motion. The relative motion of the first pontoon to the second pontoon in response to an incident wave is converted into a desired form of energy. | 03-21-2013 |
20140360176 | WAVE-POWERED ELECTRICITY GENERATOR - This invention is a wave powered electricity-generating mechanism which utilizes the fluctuations of multiple pontoons and ratchets' direction control to integrate various gear speeds into a high speed in order to drive an electricity generator. There are low, medium, and high speed gear sets. Low speed is for a quick start, higher speeds are to adopt lower speeds. The highest speed can be calculated in advance by adjusting the number of dynamic units, gear ratios, and number of transmission phases of gear sets in order to keep a designated output speed. This mechanism does not need to be fastened to the coast. Due to the independence feature of each dynamic unit, the number of dynamic units can be adjusted to meet various power output requirements. | 12-11-2014 |
20150107239 | System for Producing Energy Through the Action of Waves - A system and method for generating energy from tuning the natural frequency of masses relative to a ground plane and an external force. In some embodiments the external force is the action of the waves. The system has a first mass movable relative to the ground plane, wherein the external force induces an oscillation in the first mass relative to the ground plane. A second movable mass is carried by and movable relative to the first movable mass. The second movable mass creates kinetic energy as the result of varying the position of the second movable mass relative to the first mass. The system adjusts or tunes the frequency of various components in relation to the natural frequency of the waves. The energy created by the relative motion can be converted to various forms of energy including electrical energy. | 04-23-2015 |
20160108883 | CARPET OF WAVE ENERGY CONVERSION (CWEC) - A carpet of wave energy conversion (CWEC) device mechanically couples an absorber carpet to one or more energy converters, thereby allowing for wave energy extraction from passing waves. The absorber carpet may be flexible material of a composite material that has a low elastic modulus in a longitudinal direction (to allow for stretching), and a relatively higher elastic modulus in a transverse direction (to better couple energy from wave to converters). Such designs have minimal wave reflections and high efficiencies within a relatively short extent of deployment. The resultant converted useful energy is available as either: 1) mechanical power including direct desalinization or electrical production; or 2) hydraulic power for a number of applications (including hydraulically powered motors supplying power to powered devices including generators), or pumping of the wave medium under pressure to an alternate location for irrigation or energy storage. | 04-21-2016 |
