The utility model discloses an anti -wind formula aerogenerator, including stand, computer lab and blade isotructure, rotate on the computer lab and connect the blade, the blade wind -engaging blows the rotation. The bottom of computer lab is connected with the rotation of the top of stand, and computer lab and blade can rotate around the stand, pivot direction level, and the stand can be fixed with the angle of computer lab, can be according to the corresponding angle of wind scale adjustment of difference. When the plane at blade place was vertical state, it is the biggest that the blade wind -engaging blows rotatory speed, if wind -force is too big, rotatable computer lab makes computer lab and blade lean to a contained angle is personally submitted to the plane and the level at blade place, and blade lean's degree action of the wind big more is more little, not blown by wind -force when the level of the blade belongs to plane. When the rotational speed of blade exceedes the limit, rotate the computer lab and make the plane at blade place be the tilt state to reach the effect of despin mechanism. Extreme weather such as typhoon can be tackled, the probability that the damage appears in the blade is reduced.
