<p>A blade angle automatic regulating device includes a rotating frame (4), the outer side of which is pivoted with the back of a blade (1) and the inner side of which is connected to a blade supporting disc (5); a power device coupled with the lower end of an orientation shaft (180) for driving the orientation shaft (180) to rotate; a rotating crankshaft (190) coupled with the upper end of the orientation shaft (180) and rotating with the orientation shaft (180) synchronously; an eccentric shaft (110) arranged in an eccentric position of the rotating crankshaft (190); an eccentric disc (111) sleeved on the eccentric shaft (110) and rotating around the eccentric shaft (110) acting as the central shaft; and a blade pull rod (6), the outer end of which is rotatably connected with the blade (1) and the inner end of which is rotatably connected with the eccentric disc (111). The device can automatically regulate the windward surface of the blade to the optimum position. A vertical shaft wind power generating system including the blade angle automatic regulating device is also disclosed.</p> |
