A blade pitch control mechanism |
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). |
