摘要： A parabolic or part parabolic focusing device located in the ocean comprises wall sections which converge a parallel ocean wavefront to foci located in an air compression chamber located between the wall sections, thereby providing a wave amplification effect. An oscillating wave surface produces an oscillating air column inside the chamber to drive a self-rectifying turbine located in an outlet at the top of the chamber. The turbine comprises a rotor with radially oriented aerofoil shaped blades which are symmetrical in cross section about a transverse plane so that the turbine rotates in a single direction regardless of the oscillations in the air column. Several mechanisms to vary the pitch of the blades are also disclosed.

摘要： This invention relates to a blade pitch control mechanism and in particular to a blade pitch control mechanism for a turbine. The invention has been developed primarily for controlling the pitch of a plurality of blades of a turbine in an ocean wave energy extracting system. According to one aspect of the present invention provides a blade pitch control mechanism (1) for a turbine rotor (3) in an ocean wave energy extracting system, the mechanism including a gear assembly (5) mountable to a hub (7) of the rotor (3) for engaging a plurality of blades (9) rotatably mounted to the hub (7). Driving means (11) is operatively connected to the gear assembly (5) for rotating the gear assembly about an axis of the rotor (3), such that the driving means (11) rotates the gear assembly (5) at substantially the same speed as the rotational speed of the rotor (3) to fix the position of the blades (9) relative to the hub (7). The driving means (11) selectively varies the rotational speed of the gear assembly (5) relative to the rotational speed of the rotor (3), inducing rotation of the blades (9) relative to the hub (7) by the gear assembly (5), thereby adjusting the pitch of the blades (9).

摘要： An improved ocean wave energy extraction system is disclosed. The system includes at least one duct for receiving an oscillating water column. The duct has a first segment, a second segment arranged transversely to the first segment and a flow control segment intermediate the first and second segments. The flow control segment is configured to inhibit turbulent flow of the oscillating water column flowing within the duct. A turbine is in fluid communication with the second segment of the duct such that the turbine is driven by the fluid flow which is generated by the oscillations of the oscillating water column within the duct. The turbine rotates an electric generator to thereby generate electrical energy.
