Darrieus type floating wind turbine, has rotor with blades fitted directly to lower end of hub and indirectly fitted to end by drift arm, electricity generator driven directly or indirectly by rotor, and wedging device

摘要

The wind turbine (1) has a rotor (2) with blades (3-1) and a support hub (4) for supporting the blades. An electricity generator (5) is driven directly or indirectly by the rotor. The blades are fitted directly to a lower end of the hub and indirectly fitted to the end by a drift arm. Wedging device permits to adjust orientation of the blades or orientation of upper segments of the blades according to the speed of the wind.
