Embodiment
Below in conjunction with accompanying drawing, the present invention is done following detailed description:
As depicted in figs. 1 and 2; The magnetic suspension reversing device for wind machine that the present invention announced; Comprise tower body 14, body 1, above body 1 outside, be provided with wind transducer 2, body 1 inside is provided with suspension mechanism; Above said suspension mechanism, be provided with driving mechanism, above said driving mechanism, be provided with guider.Mainly divide three steps during the work of this magnetic suspension reversing device for wind machine: magnetic suspension, driving and guiding.(used control unit of whole process and power supply unit all are existing technologies)
One, magnetic suspension: (as depicted in figs. 1 and 2)
When wind transducer 2 detects wind direction and changes; Field coil 5 energized on the suspension magnet 3; At this moment will there be the main field of passing air gap while interlinkage electromagnet 4 and stator 6 to produce; Stator 6 is by this magnetizes, thereby produces attraction force between suspension magnet 3 and the stator 6, and wind energy conversion system body 1 is lifted.When displacement transducer 8 detected gap between stator 6 and the suspension magnet 3 and reaches 10mm, the electric current of field coil 5 made attraction force equal gravity on the adjustment suspension magnet 3, and body is suspended in the air;
Two, drive (as shown in Figure 3)
Three phase windings, 7 energisings on the stator 6 will produce rotating magnetic field, keep the magnetic pole of suspension magnet 3 constant; Then after the rotating magnetic field coupling that suspension magnet 3 magnetic fields and stator 6 are produced; Form stable Resultant magnetic field, at this moment, the magnetic pole of suspension magnet 3 rotates under the magnetic torque effect of Resultant magnetic field; And static relatively with rotating magnetic field, reach synchronous.
After wind transducer 2 detects head aligning wind direction; To send signal and give control unit 13; Power supply unit 12 stops three phase windings, 7 power supplies on stator 6 then; Progressively reduce simultaneously the electric current of field coil 5 on the suspension magnet 3,, make body 1 return to normal operation position gently until stopping power supply;
Three, embodiment's one guiding (as shown in Figure 1)
In rotary course; When displacement transducer 8 detects when squinting about body 1 takes place; The guiding electromagnet 9 that is installed on the body 1 interacts with stator 6 sides, makes body 1 return to the normal position, and control unit 13 is through controlling the electric current in the guiding electromagnet 9; Gap between body 1 and stator 6 sides is remained unchanged, normally rotate along guide rail 10.
Four, another embodiment's guiding (as shown in Figure 2)
In rotary course,, body 1 is normally rotated along guide rail 10 because the effect of ball 11 can guarantee to squint about body 1 can not take place.
