Therefore, the design, quality and performance of the blade are the determining factors for the normal and stable operation of the wind generating set. In the prior art, the resistance type blade has better starting capability because the resistance drives the blade to rotate and the torque is larger. However, because the size and direction of wind power are constantly changed, when the wind speed is too high and the resistance type blade is at a high rotating speed, the resistance type blade can generate resistance for resisting rotation to the whole wind power generation system, so that the rotating efficiency is reduced, and the generating efficiency is reduced. When the wind speed is too high, the blades are also easily abraded and damaged, so that the safety of a wind turbine system device is weakened; it is often necessary to stop the operation of the blades to avoid damage to the wind turbine system equipment, which can significantly compromise the wind energy utilization factor.

Detailed Description

Referring to fig. 1-3 in a coordinated manner, the utility model provides an automatic start-stop formula wind blade device of resistance type, including a pair of circular guide pivot 1 and several can be on this two circular guide pivot 1 pivoted and form angle interval's resistance type blade module 2 each other, wherein:

each resistance type blade module 2 comprises a frame body 3, blades 4 and a base 5; the frame body 3 and the base 4 are integrally formed, the frame body 3 is in a semi-arc cylindrical shape and is provided with at least one blade opening 6; sleeves 7 are arranged at four corners of the concave surface of the blade opening 6; the blades 4 are in a semi-arc sheet shape; a vane shaft 8 is arranged on one side of the vane 4, and the vane shaft 8 is arranged in the sleeve 7 to lead the vane 4 to swing relative to the vane opening 6; at least one blade 4 is correspondingly arranged on each blade opening 6; the base 5 is provided with a bearing wheel 9, and the bearing wheel 9 rolls on the double-circular guide rail rotating shaft 1; the bases 5 of two adjacent resistance type blade modules 2 are connected through a traction pull rod 10.
