<p>A wind power station with a carousel rotor with vertical rotation axis, fitted with supporting structure and a generator (2) driven by the rotor, with the rotor equipped with a three-arm driving structure (4) located at the bottom and containing three identical blades (7), whose lower pins are situated in bearings located at the ends of drive arms (6) and the upper pins are seated in bearings located at the ends of arms (13) of a fixing structure (12), wherein the blades (7) are connected through position gears of 1:2 ratio to the set of central gear wheels (15), (16), (17), which is fixed coaxial with the rotor rotation axis and whose angular position in relation to the drive structure (4) arms (6) sets the mechanisms of setting the rotor to the direction of the wind, characterized by the fact that each of the central-set gear wheel (15), (16), (17) of its rotor is fitted with one sleeve (19), (20), (21), and the sleeves (19), (20), (21) are rotary in relation to each other and are rotary in relation to the supporting structure, and each sleeve (19), (20), (21) has cam grooves (A), (B), (C) situated at the opposing sides of the slide surface, through which a pin (22), common to all sleeves (19), (20), (21), crosses radially, determining the angular position of the sleeves (19), (20), (21) in relation to each other as well as the angular position of the set of sleeves (19), (20), (21) in relation to the supporting structure, wherein the grooves (A) of the first sleeve (19) are axial in relation to the axis of the rotor rotation, the grooves (B) in the second sleeve (20) are set oblique left or right hand in relation to the axis of the rotation of the rotor and the grooves (C) in the third sleeve (21) are set oblique in the opposite direction to that of the grooves (B) of the second sleeve (20), and that the pin (22) is fixed on a push-rod (23) connected to at least one actuator (24), and the actuator (24) is fixed on the supporting structure and via push-rod (23) drives the pin (22) axially in the grooves (A), (B), (C) of the set of sleeves (19), (20), (21) and forces a relative rotation of the second (20) and third (21) sleeves in relation to the first sleeve (19) while maintaining the angular position of the first sleeve (19) in relation to the supporting structure.</p> |
