Magnetic suspension vertical turbine wind generator

Abstract

The invention discloses a magnetic suspension vertical turbine wind generator. A wind guiding passage of a turbine and an axis line parallel to the wind direction form an included angle of 35 to 40 degrees; an axial bearing structure consists of a main bearing part consisting of a magnetic bearing and an auxiliary bearing part consisting of mechanical rollers; the mechanical rollers are distributed symmetrically and circularly arranged on an object stage of a tower base; the magnetic bearing comprises active suction type electromagnet coils which are vertically arranged above and below a main working shaft cam to correspondingly form a working unit, all working units are equally distributed in circular symmetry and arranged outside the mechanical rollers in concentric circles with mechanical roller bearings, and each electromagnet unit ensures that magnetic poles are opposite; and the turbine is in a form of vertical turbine structure. The wind generator has a reasonable structure, can obtain higher generating efficiency under the condition of low wind speed, and has the advantages of low starting wind speed, high wind energy utilization efficiency, simple structure and convenient maintenance.

Description

Technical field:

[0001] The invention relates to a vertical wind power generator, in particular to a magnetic levitation vertical turbine wind power generator. Background technique:

[0002] At present, wind turbines are divided into horizontal and vertical types according to the working mode of the main shaft. Horizontal wind turbines have been widely used and have more mature practical experience. However, the horizontal wind turbine blades have a large diameter and a high base, which is inconvenient for inspection and maintenance, and consumes building materials; the rotating blades have a small effective wind surface and large operating noise, which is likely to injure passing birds and start the wind speed. Large, suitable for areas with abundant wind resources. Summary of the invention:

[0003] The purpose of the present invention is to provide a magnetic levitation vertical turbine wind generator that can obtain high power generation efficiency under low wind speed condi...
