A modular wave energy converter includes: a forward attachment frame; forward guide rails coupled to the forward attachment frame; a forward paddle coupled to the forward guide rails; and one or more forward tethers coupled to the forward paddle and the shaft. A combination of heave and surge forces from waves of water causes the forward paddle moves up and down the forward guide rails. The movement of the forward paddle moves the one or more forward tethers. The movement of the one or more forward tethers causes the shaft to rotate via the rotation of winches. The winches are configured with a one-way clutch, which allows the shaft to rotate in a first direction but not a second. The converter has the same structure on the aft side, including an aft paddle. The forward and aft paddles are positioned vertically or inclined.

MECHANICAL ENGINE FOR THE GENERATION OF ENERGY THROUGH WATER MOVEMENT, refers to a mechanical motor (1) to (41), with their auxiliary sets, with the objective of generating mechanical and electrical energy, or both, being plants electric lines with this system can be built on the banks or inside the sea, river or islands, where the cost benefit of the energy by the conventional way, does not become compensating, or practically inaccessible places, but that have waves, tides, or level differentials in waters. As these sources of energy, in water there are in abundance on the planet, possible future plants of this system, may be more spread out, and in greater quantity, thus reducing the number of posts, towers, compensation equipment, components, and transmission wires. In case of use in water navigation, this engine can be used to replace, totally or partially, conventional fuels and engines, for mechanical handling, and the generation of electric energy on board.

A wave-direction-adaptive wave focusing type wave energy convertor with multiple water channels, comprising an energy acquisition system, an energy conversion system and a support system. Wave focusing is carried out through double water channels, so that the movement amplitude of water particles behind a box is doubled. A device is connected with a fixed pile through universal bearings, so that an opening of the device is always faced to a wave flow direction, which adapts to different seasons and water conditions, has low environmental requirements, and can be used in a wide sea area. Several coils of pretension spring compression are arranged in a winding barrel, so that a nylon rope connected to a buoy is ensured to be always in a straightened state and not derail from pulley blocks to work abnormally due to looseness whether the buoy is at a wave crest or a wave trough.

Disclosed are a wave power generation system for generating electrical energy by means of a hydraulic circuit, and a method for controlling same. The wave power generation system comprises a hydraulic motor for storing motion energy in a form of fluid pressure and volume if a plurality of tension transmission members, for transmitting motion energy by means of six-degrees-of-freedom motion of a movable object floating on the waves, move in one direction, and for maintaining the tension of the tension transmission members by means of the stored energy if the tension transmission members move in the other direction. Electric energy is alternately generated by means of the bidirectional motion of the plurality of tension transmission members.

A wave energy converter (10) is capable of floating on a body of water (BW), moving in response to waves (W) occurring in the body of water (BW), and includes a hull (12) connected to a heave plate (14). The wave energy converter (10) is characterized in that the hull (12) is formed from reinforced concrete, a plurality of connecting tendons (16) extend between the hull (12) and the heave plate (14), and a power take off (66) is attached to each connecting tendon (16).

Disclosed are a wave force generation system for producing electric energy by a hydraulic circuit and a controlling method. The wave force generation system comprises a power conversion portion including a hydraulic cylinder which generates a hydraulic pressure by six degrees-of-freedom motion of a moving object floating on waves, wherein: when force is applied to the hydraulic cylinder in one direction thereof, the power conversion portion makes a fluid flow along a first path so as to produce electric energy; and when force is applied to the hydraulic cylinder in the other direction thereof, the power conversion portion makes the fluid flow through second path which makes the fluid bypass and flow in a direction opposite to the first path, whereby the fluid in the second path meets the first path and thus can produce electric energy.

A modular wave energy converter includes: a forward attachment frame; forward guide rails coupled to the forward attachment frame; a forward paddle coupled to the forward guide rails; and one or more forward tethers coupled to the forward paddle and the shaft. A combination of heave and surge forces from waves of water causes the forward paddle moves up and down the forward guide rails. The movement of the forward paddle moves the one or more forward tethers. The movement of the one or more forward tethers causes the shaft to rotate via the rotation of winches. The winches are configured with a one-way clutch, which allows the shaft to rotate in a first direction but not a second. The converter has the same structure on the aft side, including an aft paddle. The forward and aft paddles are positioned vertically or inclined.
