Rotary positioning device and its application method

A counterweight self-rotating power generating device, comprising a motor, a counterweight self-rotating power unit, at least one flywheel and at least one power generating device, said counterweight self-rotating power unit comprising a pair of power wheels arranged in a corresponding manner and with an axial offset and at least one counterweight unit pivotally disposed between said two power wheels, said power wheels being respectively disposed on a respective power wheel shaft on a frame, said counterweight unit being provided with two axis-offset shafts on both sides thereof, said two axis-offset shafts being respectively pivoted on respective inner surfaces of said two power wheels, said frame being equipped with said motor and a synchronous shaft, said motor driving said synchronous shaft on said frame through a reducer to make said synchronous shaft rotate, two first intermediate transmission shafts being provided on said frame corresponding to said synchronous shaft and said two power wheels, said synchronous shaft synchronously driving said two first intermediate transmission shafts to synchronously drive said power wheels to rotate, said counterweight units being kept moving in the same horizontal direction when said power wheels rotate, so that the gravity generated by the said counterweight unit on one side of the center of said power wheels effectively drives said power wheels to rotate and at the same time, the said counterweight unit located at the other side of the center of said power wheels is hidden inside said power wheels, so that when said power wheels rotate, the load force on one side of the center of said power wheels is much smaller than the effective thrust generated by said counterweight unit on the other side of the center, so that said power wheels have enough counterweight gravity to generate continuous rotation, said at least one flywheel being disposed on said frame, each said flywheel being disposed on a flywheel shaft, a second intermediate transmission shaft being disposed on said frame between each said flywheel and each said power wheel, so that said two power wheel shafts simultaneously drive the said two power wheel shafts simultaneously drive the said second intermediate transmission shaft between each said flywheel and each said power wheel to rotate, and then the said second intermediate transmission shaft drives the said flywheel to rotate to generate inertial kinetic energy, and finally the said flywheel drives the said power generating device to generate electricity.
