Accompanying drawing explanation:

The perspective view that accompanying drawing 1 is open wind-driven generator, therefrom visible, wind wheel 1, rotor shaft 2, rotor shaft air guide sleeve 3, rotor shaft bearing sleeve 4, the horizontal right angle side 5 of triangle connecting plate, the triangle connecting plate straight vertical arm of angle 6, keyway 7, rotor shaft 8, rotor core 9, stator coil 10, frequency variator 11, pressure bearing 12, pylon 13, triangle connecting plate 14, waterproof jacket 15, magnetic stripe frame 16, magnetic stripe 17, shell 18, rotor 19, trim ring 20, transformer 21, transformer air guide sleeve 22, support 23, hollow vertical shaft 24 etc.

Accompanying drawing 2 is rotor sectional view (amplification), therefrom visible rotor shaft 8, rotor core 9, magnetic stripe frame 16, magnetic stripe 17, interior spline 25 etc.

Embodiment:

As shown in Figure 1, wind wheel has former and later two, and wind wheel 1 is above less, and wind wheel is below larger, rotor shaft 2 is above shorter, rotor shaft is below longer, and this design is in order to give wind wheel directed, distinguished and admirable while laterally blowing, larger rear wind wheel and long rear rotor shaft have determined can be subject to larger moment of torsion below, its inevitable falling off head, plays the effect of empennage, therefore can realize generator automatically with the wind.

There is outside keyway 7 at two inside two ends of rotor shaft, and there is hollow groove at outside two ends.

Front rotor shaft and rear rotor shaft respectively have two bearings, two bearing housings 4, have at least three triangle connecting plates 14 and an air guide sleeve 3 to form; The two ends of a horizontal right angle side 5 of triangle connecting plate 14 are fixed on two bearing housings, and the other end of another right angle side 6 is fastened on the end face of generator casing 18; Air guide sleeve 3 use plastic productions, its oral area has inside flange, and this flange snaps in the hollow groove of rotor shaft 2 outer ends.
