Magnetic levitation device for vertical-axis wind turbine

Abstract

The invention provides a magnetic levitation device for a vertical-axis wind turbine. The magnetic levitation device for the vertical-axis wind turbine comprises a main upright post, a lower flange, a generator, an upper flange, a fan blade rotating shaft, a magnetic levitation stationary element, a magnetic levitation rotating element, a first permanent magnet and a second permanent magnet, wherein the magnetic levitation stationary element is fixedly arranged at the upper end of the main upright post; the magnetic levitation stationary element is fixedly connected with the generator through the lower flange; the fan blade rotating shaft is fixedly connected with the magnetic levitation stationary element through the upper flange; the magnetic levitation stationary element is fixedly connected with the generator; the first permanent magnet and the second permanent magnet are fixedly arranged on the magnetic levitation stationary element and the magnetic levitation rotating element respectively; the first permanent magnet and the second permanent magnet are opposite up and down cross the air; and the adjacent surfaces are the same in polarity. The magnetic levitation device for the vertical-axis wind turbine is simple in structure, relatively low in cost and convenient to install, can effectively improve the efficiency and the operating stability of the generator when used, prolongs the service lifetime of the generator and can effectively ensure that a blower does not easily fall off in extreme weathers of a high wind and the like.

Description

technical field [0001] The invention relates to auxiliary facilities for wind power generators, in particular to a magnetic levitation auxiliary device suitable for vertical axis wind power generators. Background technique [0002] Vertical axis wind turbines are currently widely used. For common vertical axis wind turbines, the generator is usually fixedly installed on the upper end of the main pole or tower through the connecting flange; the rotating shaft of the wind blade is directly fixed on the top of the generator, and the existing problems are as follows: 1. One is that the generator is subjected to a large force, which affects the operation stability and service life of the generator; the other is that in extreme weather conditions such as typhoon, the top of the generator is prone to be torn and damaged, and in severe cases, the fan may even fall and cause injuries. ACCIDENT. Contents of the invention [0003] The purpose of the present invention is: aiming at ...
