<p>A movable-blade variable-speed type wind turbine comprises an engine compartment (107) and a wind blade-driving assembly (130) positioned on the upper portion of the engine compartment (107). The wind blade-driving assembly (130) consists of a wind wheel (102) and a vertical axis rotation system (101). The wind wheel (102) comprises a plurality of wind blades and a wind-blade support on the vertical axis rotation system (101). The wind-blade support consists of an upper support (109) and a lower support (108) arranged laterally to the vertical axis rotation system (101). The upper end and lower end of the wind blades are connected to the upper holder (109) and lower holder (108), respectively. The wind blades consist of lift-type blades (103) arranged on the wind-blade support and a movable-blade group (114,117). The lift-type blades (103) have extensions (110,120) in their longitudinal direction. The movable-blade group (114,117) is rotatably connected to the lift-type blades (103) or their extensions (110,120).</p> |
