Background technique

In the existing middle-size and small-size pitch-controlled wind-driven generator; most of wind-driven generators all are based on the driftage wind-power electricity generation; starting torque is big; generator is difficult to start under gentle breeze, and can't speed limit, all is to come the oneself to rotate by the wind-force size; the output power instability; Security is all relatively poor, under the hurricane situation, and effectively self-protection.

Summary of the invention

The objective of the invention is provides a kind of high efficient and reliable feather for the deficiency that solves above-mentioned technology, and low wind speed starts speed limit under the strong wind, the middle-size and small-size pitch-controlled wind-driven generator of hurricane autostop.

In order to achieve the above object, the middle-size and small-size pitch-controlled wind-driven generator that the present invention is designed, it mainly comprises generator, wheel hub, solid of rotation, bearing chamber and vertical shaft, the front end of generator connects wheel hub by main shaft, wheel hub is provided with hubcap, the fixedly connected solid of rotation in the rear end of generator, the bottom of solid of rotation connects vertical shaft by bearing chamber, it is characterized in that annular uniform fan blade coupling shaft on the described wheel hub, the fan blade coupling shaft is provided with centrifugal hammer, the end that the fan blade coupling shaft is arranged in the wheel hub is connected with lazy-tongs, and lazy-tongs are connected with the synchronous disk that is arranged on rocker arm one end, between synchronous disk and the hubcap Returnning spring are set, rocker arm passes main shaft and extend in the solid of rotation, and cooperates for moving between rocker arm and the main shaft; Be connected with moving arm by the brake stand hinge in solid of rotation, an end of moving arm contacts with rocker arm, and the other end of moving arm is connected with brake lever; Brake lever is passed bearing chamber and is extend in the vertical shaft.The characteristics of this structure are that the fan blade coupling shaft is connected with synchronous disk by lazy-tongs, all fan blade coupling shafts can both rotate around the axle center free synchronization of fan blade coupling shaft according to the centrifugal force that is produced by centrifugal hammer in the wind-driven generator rotation process, realize regulating the purpose of pitch.Synchronous disk is connected on the rocker arm simultaneously, and rocker arm can be controlled by moving arm by brake lever, and the control brake lever can change the position of synchronous disk, thus control fan blade coupling shaft, and final the realization changes pitch, reaches the purpose of brake.Moreover, by because brake lever to the control of synchronous disk, can be limited to the shift motion of synchronous disk in certain scope, reach the purpose of the change oar scope of restriction fan blade coupling shaft.

For the further breeze start-up that improves wind-force electrical machinery, the performance of strong wind speed limit, the center line of described fan blade coupling shaft is tangent with the circle that with the hub body center is the center of circle, is fixed by nut between fan blade coupling shaft and the wheel hub.Between rocker arm and moving arm, be provided with clamping stopper bearing, improve the fiting effect between rocker arm and the moving arm.Generator and solid of rotation pass through bolt, and two bearings cooperate with vertical shaft about being provided with in the transmission of electricity slip ring that is provided with in the vertical shaft, bearing chamber, and solid of rotation is provided with loam cake outward, and solid of rotation is sealed, and also maintains easily maintenance.

The resulting middle-size and small-size pitch-controlled wind-driven generator of the present invention; the agent structure compactness; realized that middle-size and small-size wind-driven generator decides the go off course lifting of technical merit of variable-pitch variable-speed of oar by upwind; on efficient and reliability, be greatly improved; it is lower to have realized that wind-driven generator starts wind speed; fan operation is safer under the strong wind; the various optimizational functions that hurricane is effectively shut down down; and can access stable output power; better protection is come generator itself, and maintenance is also very convenient in application process.

Embodiment

The invention will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1:

The middle-size and small-size pitch-controlled wind-driven generator that present embodiment is described, it mainly comprises generator 4, wheel hub 7, solid of rotation 6, bearing chamber 9 and vertical shaft 10, the front end of generator 4 connects wheel hub 7 by main shaft, wheel hub 7 is provided with hubcap 8, the fixedly connected solid of rotation 6 in the rear end of generator 4, the bottom of solid of rotation 6 connects vertical shaft 10 by bearing chamber 9, annular uniform fan blade coupling shaft 2 on the wheel hub 7, fan blade coupling shaft 2 is provided with centrifugal hammer 3, and the end that fan blade coupling shaft 2 is arranged in the wheel hub 7 is connected with lazy-tongs 11, lazy-tongs 11 are connected with the synchronous disk 21 that is arranged on rocker arm 13 1 ends, between synchronous disk 21 and the hubcap 7 Returnning spring 12 is set, rocker arm 13 passes main shaft 21 and extend in the solid of rotation 6, and cooperates for moving between rocker arm 13 and the main shaft 20; Be connected with moving arm 17 by brake support 15 hinges in solid of rotation 6, an end of moving arm 17 contacts with rocker arm 13, and the other end of moving arm 17 is connected with brake lever 19; Brake lever 19 is passed bearing chamber 9 and is extend in the vertical shaft 10.Wherein said lazy-tongs are made of the joint shaft bearing that ight soil is connected on synchronous disk and the fan blade coupling shaft.
