Wind driven generator with double wind wheels with power synthesis

Abstract

The invention discloses a wind-driven power generation device and particularly discloses a wind driven generator with double wind wheels with power synthesis. The wind driven generator with the double wind wheels with power synthesis is characterized by comprising a front wind wheel and a back wind wheel, wherein a mechanical synthesis mechanism for connecting the front wind wheel and the back wind wheel is installed between the front wind wheel and the back wind wheel, the front wind wheel and the back wind wheel respectively do work, and the work drives the generator together after the work is synthesized by the mechanical synthesis mechanism. In the wind driven generator with the double wind wheels with power synthesis, one wind wheel is designed behind the front wind wheel, the residual kinetic energy of the front wind wheel after doing the work is recycled, and the work done by the front wind wheel and the back wind wheel drives the generator together after the work is synthesized by the mechanical synthesis mechanism. The structure has the results that the output power of a wind driven generator with the same specification is enhanced by about 60 percent, the utilization rate of wind resources is enhanced, and the economic benefits of the yield and the operation of power generating equipment for wind power generation are enhanced. Meanwhile, a tower is safer by the supporting counter torque of a deboosting tower post.

Description

(1) Technical field [0001] The invention relates to a wind power generating device, in particular to a power combining double wind wheel wind power generator. (2) Background technology [0002] The wind energy utilization rate C of the current prior art wind power generator p Not high, Bezier limit is 0.593, this is just a theoretical value, the actual wind turbine C p It is only about 0.4, and more than half of the wind energy is not utilized. It is generally accepted that the spiral vortex formed after the wind rotor blades exhausts the energy by itself. At present, the unit power investment of wind power generation is relatively high, but the output is low, so the economy is poor. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides an economical and applicable double wind wheel wind generator with high utilization rate of wind energy. [0004] The present invention is achieved through the followi...
