Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model embodiment provides a kind of wind-driven generator stabilized-speed pitch control device, comprising: blower fan head, gear 3, motor 5, drive unit 8, push rod 7 and push rod supporter; Push rod 7 is arranged in motor 5, and one end of push rod 7 is connected with blower fan head, and the other end is connected with drive unit 8.
In existing stabilized-speed pitch control device, drive unit 8 is arranged on the wheel hub 12 of blower fan head conventionally, and wheel hub 12 rotates for a long time, the large drive unit 8 that easily damages of its centrifugal force.The wind-driven generator pitching smooth rate apparatus the utility model proposes, by drive unit 8 postposition, strong protection drive unit 8, extended working life of wind-driven generator stabilized-speed pitch control device.In addition, drive unit 8 is connected with push rod 7, and push rod 7 is connected with blower fan head, under wind effect, can a set of mechanism become fast oar, has changed and in prior art, has separately become the problems such as the change oar that oar brings is slow, speed stabilizing effect is not obvious.
Preferably, be provided with motor shaft 6 in motor 5, motor shaft 6 is connected with blower fan head.
Preferably, in drive unit 8, be provided with live axle 9; Live axle 9 is connected with push rod 7 by link 13.
Preferably, drive unit 8 comprises oil cylinder or cylinder, and live axle comprises oil cylinder axle or cylinder axis.
Preferably, link 13 comprises: bearing, bearing shell or screw.
