Wind power installation comprising a provisions of the rotor blade and method of operation of such wind power installation

摘要

Wind power installation, comprising a turnstile with at least one blade (2) of elongated rotor, which is mounted on the hub (3) of rotor reel by means of a set (1; 1 ', 52) bearing having two elements (13, 14; 13 ', 14'; 53, 54) annular mutually rotatable to directly or indirectly connect, on one side, with the end (5) rear sheet (2) of rotor referred, and the hub (3) of the rotor reel on the other, and at least two raceways mutually offset axially bodies (24, 25; 61, 62) rotating roller, wherein the bodies (24, 25; 61, 62) running two raceways mutually axially displaced an approximately cylindrical shape, ie, a side surface (26) each, which is symmetric rotationally with respect to exactly one axis (31; 69; 70) of rotation 2; in particular shaped cylinder, cone, needle, barrel, said bodies (24 being oriented 5; 61, 62) rolling so that their axes (31; 69; 70) of rotation intersect the longitudinal axis of the blade (2) of rotor relating an angle that is between 30 and 90 degrees, and the blade (2) of the rotor being in the form of a side surface (4), which surrounds a interior cavity whose lateral surface (26) a path cylinder jacket at the end (5) rear of the blade (2) of the rotor is converted to a surface (6) butt joint, rear, characterized in that on the surface of rear attachment are provided perforations (7) blind, arranged in a crown, which, on the one hand, lead to a body (8) anchor, mounted on the blade (2) of the rotor, a hard material, for example, iron, continuing as threaded holes interiorly, and on the other hand, correspond in terms of number, diameter and orientation with perforations (17; 57) passing, arranged in a crown element (13; 13 '; 53) the respective joint, so that are in extension and therefore p ermitan inserting a bolt (19) anchoring in each.
