Further, described active fast pulley and driven fast pulley are taper cone pulley, and described active movable wheel and driven movable wheel are taper cone pulley.
Further again, described stepless speed variator is connected in the cabin seat through elastic support.
Technical conceive of the present utility model is: acceleration equipment is between main shaft and generator, and be connected on the seat of cabin, acceleration equipment is a stepless speed variator, by the active fast pulley, the active movable wheel, driven fast pulley, driven movable wheel, active cylinder, slave cylinder and driving belt are formed, initiatively movable wheel and driven movable wheel are enclosed within respectively on the central shaft of the central shaft of fast pulley initiatively and driven fast pulley, connect through driving belt, with transfer motion power, active cylinder and slave cylinder lay respectively at a side of active movable wheel and driven movable wheel, the active movable wheel, active cylinder and driven movable wheel, slave cylinder forms two hydraulic chamber respectively, form V-shaped groove between fast pulley and the movable wheel, driving belt is meshed with active wheel in groove.
The control system of wind power generating set is according to the operating mode of unit operation, after received sensor signal is analyzed, by actuator the axial position of active movable wheel and driven movable wheel regulated continuously.
When movable crop rotation moves axially, can change initiatively fast pulley and the initiatively Pitch radius of movable wheel, driven fast pulley and driven movable wheel, thereby change the velocity ratio between driving wheel and the follower, realize the stepless change transmission.
The utility model stepless speed change type wind power generating set, increased the wind speed range that to generate electricity, and when, wind speed round less when wind speed is low, increased the rotating speed of generator, thereby increased generated energy, improved wind energy utilization, reduced cost of electricity-generating by increasing velocity ratio; By stepless change, effectively reduce the vibration and the load impacting that cause because extraneous wind speed changes, the working life of having improved component; Stepless change makes that the tachometer value of generator is an optimal value, therefore generator has been played protective action.
The beneficial effects of the utility model mainly show: 1, increased generated energy, improved wind energy utilization, reduced cost of electricity-generating; 2, relax vibration and impact, improve component working life; 3, generator had protective action; 4, principle is simple.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-Fig. 4, a kind of stepless speed change type wind power generating set, comprise pylon 15, cabin 16, wind wheel 17, be provided with cabin seat 11, main shaft 12, stepless speed variator 13 and generator 14 in the described cabin, cabin seat 11 is connected with pylon 14, and can go off course according to wind direction, and described main shaft 12 is connected with wind wheel 17, stepless speed variator 13 and is connected in cabin seat 11 through elastic support between main shaft 12 and generator 14.Stepless speed variator 13 is made up of active fast pulley 1, active movable wheel 3, driven fast pulley 2, driven movable wheel 4, active cylinder 5, slave cylinder 6 and driving belt 7.
Described active fast pulley 1 is fixedlyed connected with main shaft 12, and driven fast pulley 3 is fixedlyed connected with the input shaft of generator 14.
Initiatively movable wheel 3 and driven movable wheel 4 are enclosed within respectively on the central shaft (201) of the central shaft (101) of fast pulley initiatively and driven fast pulley, connect through driving belt 7, with transfer motion power, active cylinder 5 and slave cylinder 6 lay respectively at a side of active movable wheel 3 and driven movable wheel 4.Initiatively movable wheel 3, active cylinder 5 and driven movable wheel 4, slave cylinder 6 form two hydraulic chamber 8 respectively, initiatively formed a V-type groove respectively between fast pulley 1, driven fast pulley 2 and active movable wheel 3, the driven movable wheel 4, driving belt 7 is positioned at groove and meshes respectively with active fast pulley 1, active movable wheel 3 and driven fast pulley 2, driven movable wheel 4.
Control system receives the signals such as wind direction, wind speed, wind speed round, driftage angle, wind wheel locking and high speed shaft brake that each sensor is gathered, these signals are analyzed the back send operational order to actuator, thus the axial position of control active movable wheel 3 and driven movable wheel 4.
