Abstract:
1. A stabilizing apparatus, applicable to a wind turbine rotor of a vertical axis wind turbine (VAWT), said stabilizing apparatus comprising: at least two rolling units; at least two guiding units, symmetrically arranged, each said guiding unit extending from a center area of said stabilizing apparatus outward to an edge of circumference of said stabilizing apparatus, each said guiding unit having a housing space inside, with said rolling units evenly distributed inside the housing spaces, an inner wall of each said guiding unit at a bottom of said housing space forming a guiding track, said guiding track extending from the center area of said stabilizing apparatus outward to the edge of the circumference of said stabilizing apparatus, a line connecting starting and ending points of said guiding track forming an angle of 0-45° to a horizon surface, said rolling units rolling along the guiding tracks towards the edge of the circumference of said stabilizing apparatus because of centripetal force when said stabilizing apparatus is rotated with said wind turbine rotor, rotational inertia of said wind turbine rotor being changed as a distance between said rolling units and a center point of said stabilizing apparatus so as to achieve stabilizing rotation of said wind turbine rotor and easy starting of said wind turbine rotor; and at least an engaging unit, for engaging said guiding units and fixing relative positions between said guiding units; wherein said rolling units are solid balls.
