Work, is not particularly suitable for the relatively low regional wind-power electricity generation of long-term wind speed.
The content of the invention
Present invention aims at a kind of low wind speed magnetic suspension wind wheel device is provided, start fast, rotating speed in the case of wind speed
It hurry up, be particularly suitable for using in the relatively low regional wind-power electricity generation of long-term wind speed；To reach that above-mentioned purpose is adopted the technical scheme that：
A kind of low wind speed magnetic suspension wind wheel device, including the rotating shaft vertically set, it is same successively from below to up in rotating shaft
Axle is fixed between at least one layer of wind wheel hub, every layer of wind wheel hub and is fixedly connected by dividing plate, consolidates in the bottom surface of bottom wind wheel hub
Surely there is bottom plate, top plate is fixed with the top surface of top wind wheel hub, coaxially support plate and constrainer discs are fixed with rotating shaft, it is described
Support plate is located at below bottom plate, and constrainer discs are located above top plate, and circumferencial direction is all provided with around the shaft in support plate and on constrainer discs
There are multiple magnets, the magnetic pole of the magnet is vertically set, turning in the rotating shaft below support plate and above constrainer discs
It is equipped with magnet segment in axle, the magnetic pole vertical rotation axis center line of the magnet segment sets to direction and forms one and be in around rotating shaft
The radial magnetic field of circumference diverging.
It is preferred that, the wind wheel hub includes multiple air blades that circumferencial direction is uniformly laid around the shaft, the air blade bag
The rectangular slab being vertically arranged is included, the inner edge of rectangular slab is fixedly connected with rotating shaft and the normal orientation of rectangular slab and junction is in the inverse time
Pin angle C, angle C are 90 ° ~ 110 °；It is integrally formed with the outward flange of rectangular slab along the segmental arc bent counterclockwise, each rectangle
Segmental arc outer end on plate is located on same circumference.
It is preferred that, circumferencial direction is provided with multiple inner ring magnets, multiple outer ring magnets, the outer ring around the shaft in support plate
Magnet is located at the outer ring of inner ring magnet.
It is preferred that, the air blade is 4 ~ 8.
The advantageous effect of present invention is that：（1）This dress is realized by being embedded in magnet in support plate and constrainer discs
Put in the vertical direction fix and above and below being not in play phenomenon generation；
（2）By set in rotating shaft magnet segment ensure that rotating shaft in the horizontal direction uniform force and while occur without swing
It also avoid the problem of rotating shaft is touched with other structures, realize a kind of real suspension rotary state, thus resistance it is smaller
It can just start in the case of compared with the slow-speed of revolution；
（3）The setting of multilayer wind wheel hub is in order to have bigger motive force under identical wind conditions, so as to by wind wheel
The diameter of hub is made smaller and obtains larger rotating speed in low wind conditions；
（4）Rectangular slab enters after two adjacent rectangular slabs with the normal orientation of rotating shaft junction in 90 ° counterclockwise ~ 110 ° of setting wind
Thrust to air blade is larger；
（5）It is integrally formed with the outward flange of rectangular slab along the segmental arc bent counterclockwise, there are three effects, one is without choosing to wind direction
Select, the wind of any direction can be acted on indistinguishably on wind wheel hub；Two be when wind aweather wheel hub, due to the work of segmental arc
With the wind moved towards along segmental arc is smaller to air blade active force or even slip over segmental arc, faces or is moved towards against segmental arc
Wind it is larger to the active force of air blade, can guarantee that air blade is turned in the same direction during wind so as to have in any direction；Three
It is the mating reaction between segmental arc and rectangular slab, wind, which once enters in it, can form a whirlpool, and the effect to air blade is pushed away
Power is bigger, so as to increase the utilization ratio to wind-force.
