Power generation device for vaneless wind turbine

Abstract

The invention discloses a power generation device for a vaneless wind turbine. The power generation device comprises a support rod, a base, a plurality of movable magnet discs, a plurality of fixed magnet disc, a movable coil, a fixed coil, a coil fixing frame I and a coil fixing frame II; a wind tower is mounted at the upper end of the support rod; the middle of the support rod is fixed at the upper part of the base through a spherical hinged seat; the base is hollow; the bottom of the base is fixed on the ground through a ground support; the lower end of the support rod stretches into the base; the movable magnet discs and the coil fixing frame I are fixedly arranged at the lower end of the support rod; the movable coil is wound on the coil fixing frame I; the fixed magnet discs and thecoil fixing frame II are fixedly arranged on the inner wall of the base; and the fixed coil is wound on the coil fixing frame II. The working condition of the power generation device can be adjusted;and the power generation device is simple in structure, fewer in components, and free of a transmission mechanism, can increase the utilization ratio of an electric generator and also can reduce the manufacturing, mounting and maintaining cost of the wind turbine.

Description

technical field [0001] The invention relates to the field of wind power, in particular to a power generating device for a bladeless wind turbine. Background technique [0002] Wind energy is a renewable and non-polluting energy, which has been highly valued by various countries. Traditional wind turbines are mainly composed of blades, tail rudders, speed increasers, towers, generators, etc. The basic principle is that the blades on the wind wheel rotate under the action of the wind, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and then the generator Driven by the wind rotor shaft, it rotates to generate electricity; the power generation of traditional wind turbines depends largely on the size of the blades. The larger the blade size, the more wind energy it receives, and the corresponding increase in power generation, such as 1.5MW wind power The length of the blades is generally about 40 meters, and the diameter of the wind ...

AI Technical Summary

Problems solved by technology

If the bladeless wind turbine uses a transmission mechanism to convert energy, it will require a greater driving force, which will cause the wind tower to have an excessively large force-bearing surface
