Full Blade Tip Wind Turbine

Abstract

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.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a full-blade wind power generator in which all blades are arranged on an outer rim supported by a triangular truss-type support frame, and is suitable for various wind power generating sites. Background technique [0002] At present, most of the widely used large-scale horizontal-axis wind power generation devices powered by wind energy adopt a structure in which three blades are arranged on a traditional hub. This kind of wind power device has few blades, so the force of the wind on the impeller as a whole is small, especially the root, which accounts for about a quarter of the overall length of the blade. In order to ensure the strength, a cylindrical structure is adopted, and the aerodynamic performance is zero; Two-quarters of the length is the middle part, because of its location, for the same unit area, the torque generated is not as good as the tip of the blade; while the ...
