<p>A wind turbine with full blade tips comprises a yaw platform (3) fixed on a tower (1), a horizontal blade impeller set mounted on the yaw platform (3), a power generator (4), and a hydraulic pipeline. The horizontal blade impeller set comprises an impeller body, blades (6) mounted on the outer edge (11) of the impeller body by a blade pitch varying device (12), and a transmission-braking integrated ring (5) fixed on the periphery of the impeller body; the impeller body and a hollow rotation shaft (8) are supported and connected together by a stay cable (13), a hinged end of the blade pitch varying device (12) is fixed on the bottom end of the blade (6), a blade motion supporting end (24) is provided on a hydraulic cylinder, and the pitch of the blade (6) is varied by stretching out and drawing back a piston rod of the hydraulic cylinder; and master brake calipers (15) are disposed at two sides of a master brake disc (16) on the hollow rotation shaft (8). The impeller body is designed rationally, the blade structure is simple, the wind turbine has complete hydraulic yaw and pitch varying functions, and all blade tips are evenly stressed, so the mounting and adjustment are simple and it is safe and reliable to use the wind turbine, thereby prolonging the service life of the whole machine.</p> |
