Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1 and Figure 2, wind-driven generator, comprise hollow spindle 1, be fixedly installed on the stator in hollow spindle 1 outside, be arranged on first end cap 3 and second end cap 15 at hollow spindle 1 two ends by bearing 2, be arranged on the wheel hub 4 between first end cap 3 and second end cap 15 and be arranged on the external rotor of wheel hub 4 inboards, one end of described hollow spindle 1 is connected with coupling shaft 5, one end of coupling shaft 5 is provided with the flange 6 that is connected with tower body (not drawing among the figure), and wheel hub 4 outsides are provided with some blade roots 7 that are used for fixing wind wheel along its circumferencial direction.Stator comprises silicon sheet core 8 that is arranged on hollow spindle 1 outer middle side part and the armature winding 9 that is wrapped on the silicon sheet core 8, wheel hub 4 inboards along the circumferential direction are provided with some wheel hub muscle 10, and described external rotor comprises the rotor yoke 11 that is fixed on the wheel hub muscle 10, be arranged on a plurality of permanent magnets 12 on rotor yoke 11 inner side surfaces and be used for the parting bead 13 of space between adjacent permanent magnet 12.In order to prevent that rainwater from causing damage to the utility model, can above first end cap 3 that is positioned at hollow spindle 1 upper end, rain-proof cover 14 be set.For the heat that produces in the generator for electricity generation process dissipates fast, be respectively arranged with some radiation holes 16 on described first end cap 3 and second end cap 15.One end of described hollow spindle 1 is connected with lightning conductor 17.
Working principle of the present utility model is: the utility model can have dual mode (rectilinear and horizontal) to be connected on the tower body, if when being installed in the utility model level on the tower body, then install on horizontal wind wheel and the lightning conductor 17 on the blade root 7 on the wheel hub 4 anemoscope can be installed, be used for detecting at any time wind speed, use for automatic control system.If the utility model is vertically mounted on the tower body, then the blade root 7 on the wheel hub 4 is fixedlyed connected with rectilinear wind wheel.When the utility model was vertically mounted on the tower body, lightning conductor 17 can prevent that thunder and lightning from causing damage to the utility model.Be that the utility model can satisfy demand rectilinear and the horizontal generating.Though the Placement of the utility model and tower body can be different, the power generation process of two kinds of Placements is identical.Because adopted external rotor to rotate the form of generating, promptly stator does not rotate, and so wind wheel is installed in wheel hub 4 outsides, just can reduce the length of hollow spindle 1, and need not to utilize rotor shaft to drive wheel hub 4 and rotate, reduced cost of production, and transportation and installation difficulty.
