Direct push type impeller of wind-driven and hydroelectric generator

Abstract

The invention discloses a direct push type impeller of a wind-driven and hydroelectric generator, which comprises a revolving shaft, a plurality of vane rods and an even number of vanes, wherein the vane rods are fixedly connected with the revolving shaft and the vanes, the vanes are distributed in central symmetry by taking the revolving shaft as the center, the revolving shaft is connected with a power input end of a gear speeder of the generator, and each vane comprises an arched plate and two baffle plates. Because of the special structure of the direct push type impeller of a wind-driven and hydroelectric generator, the impeller can obtain the maximum fluid mechanical energy utilization ratio and can lower the generation cost under the condition of zero pollution. Repeated tests prove that compared with the traditional three-vane flat round-surface diagonal push type impeller, the power generated by the direct push type impeller of a wind-driven and hydroelectric generator can be increased by more than ten times under the conditions of the same vane length, the same vane area and the same wind power. Besides, the direct push type impeller of a wind-driven and hydroelectric generator in the invention has simple structure and is easy to implement.

Description

technical field [0001] The invention relates to an impeller of a wind power generator and a water power generator, in particular to a direct-push impeller capable of improving the utilization rate of wind power and water power. Background technique [0002] The principle of the wind turbine is similar to that of the hydroelectric generator. They both use the principle of electromagnetic induction to convert mechanical energy into electrical energy. First, the wind or water force drives the impeller to rotate. The kinetic energy of the rotation is converted into electrical energy. It is well known that the work done on the impeller by the component force of wind force or water force in the tangential direction of the impeller is the effective work to push the impeller to rotate. The turbine impeller or three-piece flat-circular oblique thrust impeller used in traditional wind or hydraulic generators, due to the limitation of its structural shape, the component force of wind ...

AI Technical Summary

Problems solved by technology

The turbine impeller or three-piece flat-circular oblique thrust impeller used in traditional wind or hydraulic generators, due to the limitation of its structural shape, the component force of wind or hydraulic force in the tangential direction of the impeller is small, so the wind or hydraulic force The effective utilization rate is far less than 100%, so wind or water is required to have high kinetic energy to achieve the expected power generation effect
