摘要:
A wave energy converter has blades (54, 56, 57, 59) on frames (51, 52) rotating about a pivot joint (53) on a structure (4, 52, 502, 505, 86). There is reciprocating rotary motion of the frame with respect to the structure, providing reciprocating rotary input power to a mechanism (73, 94, 98). The mechanism (98) may be arranged so that the reciprocating input power is transferred to uni-directional power via pulleys (101, 106) and sprag clutches (102, 107).

A wave energy conversion system is provided including a pod, multi-radius energy transmission mechanism, and an electrical generating device. The pod is rotatably supported by a platform structure and the multi-radius energy transmission mechanism is in mechanical communication with the pod. The multi-radius energy transmission mechanism is configured to transmit a variable torque over a range of motion and is in mechanical communication with the electrical generating device.
摘要:
The invention relates to a device for the generation of energy on a structure adapted to undergo at least one reciprocating tilting movement, said device comprising side turbines (11a, 11b), an intermediate chamber (17), and side tanks (15a, 15b), each side tank containing one of the turbines and communicating with the chamber in order to provide liquid inlets and outlets. The turbines have vertical axes, and the side tanks (15a, 15b) and the turbines are disposed substantially in alignment with the direction (17a) of extension of the intermediate chamber, such that the liquid is received substantially in this alignment.

A wave energy conversion system is provided. The system comprises a buoyant apparatus (10), a tether (19), a pump (15) associated with a hydraulic circuit and a mooring (16) located on the seabed. The buoyant apparatus (10) comprises a hollow body (21) presenting an exterior surface (27). The hollow body (21) is adapted to be continuously located below a water surface during operation. The buoyant apparatus (10) is operably connected to the mooring (16), characterised in that the operable connection comprises a relief arrangement for relieving excessive loadings between the buoyant apparatus (10) and the mooring (16) as a result of wave motion.

A pipe (1) takes inside a hydraulic turbine (3) and an electric generator (4) connected to each other to generate electricity and takes a lower water inlet (10) adapted to capture the water wave (EW) that causes the rotation of the hydraulic turbine (3), a displacement device (5) being included for imparting the pipe 1 a ascending / descending movement (Fig. 5).
摘要:
According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.
