Bladeless wind driven generator based on Karman Vortex Street theory

The invention discloses a bladeless wind driven generator based on the Karman Vortex Street theory, and belongs to the field of wind power generation. The bladeless wind driven generator comprises a wind energy collecting unit, a mechanical structure unit, a power generation unit and a fixed base. The wind energy collecting unit comprises a windward mast and a spherical surface cover plate. The mechanical structure unit comprises a connecting rod, a ball hinge and a tension and compression spring. One end of the tension and compression spring is mounted on the windward mast, the other end of the tension and compression spring is mounted on a horizontal fixed plane where the ball hinge at the lower end of the mast is located, and the axis of the tension and compression spring and the horizontal fixed plane where the ball hinge is located form an angle of 45 degrees. The power generation unit comprises a permanent magnet unit and a coil induction unit. The permanent magnet unit is connected with ball hinge, and
