On navigation empennage link rod 2 tension arm 20 is installed, its purposes is: provide crooked steering torque that Point of Strength is provided for the pulling force of the traction rope of traction electric machine changes into.One end of traction rope is wrapped on the traction rope spool, the other end is connected to the other end of tension arm, when the positive direction actuation power supply is added to motor, motor drives traction rope spool retraction traction rope, because the rod end of navigation empennage link rod is associated in supported spring one end, traction rope just will make the supported spring bending when regaining, thereby make the navigation empennage from perpendicular to the position of fan blade plane of rotation to traction strut one lateral deviation from, because the navigation empennage is no longer vertical with the fan blade plane of rotation, so, under the effect of wind-force, make the fan blade plane of rotation also depart from vertically-supplying air to the position.Reduce effective blowing area with regard to the fan blade that makes blower fan like this, thereby reduced the rotating speed of generator, the output power of minimizing generator.
Three fan blades 6 of wind-driven generator at grade, this plane is called fan blade plane of rotation 7, navigation empennage coiling machine sports association fitting 11, the navigation empennage connects 2 one-tenth vertical straight lines of spring 9 and navigation empennage link rod and is connected, navigation empennage 3 is fixedly connected with the end of navigation empennage link rod 2, and the plane of navigation empennage 3 is perpendicular to the ground, form the overall navigation empennage, the substantially horizontal fixed installation tension arm 20 that connects a side of spring 9 at navigation empennage link rod 2 near the navigation empennage, at the other end of tension arm 20 navigation empennage traction rope 21 is installed, the pto of traction motor 19 overlaps fixedly connected with traction rope spool two shaft axiss, the other end of navigation empennage traction rope 21 is wrapped on the traction rope spool 24, when the 21 not tensionings of navigation empennage traction rope, the overall navigation empennage is free straight configuration.
Two position transducers are installed at the flexible position that connects spring 9 at the navigation empennage, crooked limit sensors 22 and stretch reseting sensor 23, the crooked limit sensors of the empennage that navigates as a whole and stretch reseting sensor.Their effect is to provide the signal that stops to move to traction motor 19 under extreme case, is a pair of protective gear.After traction motor 19 is carried out the positive direction actuation power supply, drive traction rope spool retraction navigation empennage traction rope 21, it is crooked that the navigation empennage connects spring 9 beginnings, when it bends to the limit (making overall navigation empennage and blower fan axially near 90 ° of angles), crooked limit sensors 22 actions, give beaming limit position signal of control system through signal transmssion line, the control system immediate cancel is applied to the positive direction actuation power supply on the traction motor 19, and traction motor 19 promptly stops action; After traction motor 19 is carried out the reverse direction actuation power supply, drive the traction rope spool and emit navigation empennage traction rope 21, the overall navigation empennage connects under the restoring force effect of spring 9 at the navigation empennage, to resetting with direction that blower fan axially overlaps, when navigation empennage connection spring 9 stretches fully, stretch reseting sensor 23 actions, stretch position signal for one of control system through signal transmssion line, the control system immediate cancel is applied to the reverse direction actuation power supply on the traction motor 19, traction motor 19 promptly stops action, and blower fan work in normal operation.
Working principle:
Implement control when native system is worked under different wind speed to blower fan, promptly blower fan is carried out the control of power output; When wind speed is no more than blower fan maximum functional wind speed, the navigation empennage traction rope 21 that is wrapped on the traction rope spool is released to not tension position, the overall navigation empennage is free straight configuration, and the overall navigation empennage is in the direction vertical with fan blade plane of rotation 7, at this moment, fan blade plane of rotation 7 becomes vertical angle with wind direction, and blower fan can be emitted in the peak output under this wind speed, and the working state that at this moment claims blower fan is a normal working; When the wind speed increasing maybe needs to reduce the output power of blower fan, add forward control voltage for traction motor 19 by control system, traction motor 19 drives traction rope spool 24 and rotates to the direction of tightening up navigation empennage traction rope 21, navigation empennage traction rope 21 is retracted, navigation empennage traction rope 21 is transmitted to the power of tightening up on the tension arm 20, because having the navigation empennage to connect spring 9 exists, make the overall navigation empennage be flexible, promptly can be crooked, under the traction of navigation empennage traction rope 21, the navigation empennage link rod 2 of overall navigation empennage is to tension arm 20 direction deflections, like this, the overall navigation empennage has just departed from the direction vertical with fan blade plane of rotation 7, under the effect of wind-force, make fan blade plane of rotation 7 also depart from the position vertical with wind direction, so just make the fan blade 6 of blower fan reduce effective blowing area, thereby the fan blade 6 of reduction generator is stressed, reduce the output power of generator under this wind speed, the electric power of sending up to blower fan drops to below the setting value, control system is cut off to forward that traction motor 19 adds control voltage, and traction motor 19 stops action immediately.If it bends to the limit (making overall navigation empennage and blower fan axially near 90 ° of angles) position, crooked limit sensors 22 actions, give beaming limit position signal of control system through signal transmssion line, the control system immediate cancel is applied to the positive direction actuation power supply on the traction motor 19, traction motor 19 promptly stops action, at this moment, claim the working state of blower fan for departing from working state.
When the working state of blower fan is in when departing from working state,, blower fan must be turned to normal working from departing from working state because of wind speed reduces when maybe needing to increase the output power of blower fan.Add reverse control voltage for traction motor 19 by control system this moment, traction motor 19 drives traction rope spool 25 and rotates to the direction of loosening navigation empennage traction rope 21, navigation empennage traction rope 21 is emitted, connect at the navigation empennage under the effect of natural restoring force of spring 9, the overall navigation empennage is to the deflection of normal working direction, stop to add reverse control voltage up to control system to traction motor 19, traction motor 19 is stopped operating, perhaps stretch reseting sensor 23 and send reset signal, control system is subjected to this signal and stops immediately adding reverse control voltage to traction motor 19, and traction motor 19 stops action.At this moment, claim that the working state of blower fan is a normal working.
25 liang of shaft axiss of the pto of traction motor 19 and traction rope spool overlap fixedly connected, and the other end of navigation empennage traction rope 21 is wrapped on the traction rope spool 25, and when the 21 not tensionings of navigation empennage traction rope, the overall navigation empennage is free straight configuration.
Because the axis of overall navigation empennage and the axis of generator have an angle to the direction of eccentric solid of rotation, the formed deflecting force of the thrust that the fan blade of wind fan causes is cancelled.When the not enough so that navigation empennage of wind speed connects spring 9 when crooked, blower fan can not gone off course, when wind speed strengthens, the navigation empennage connects spring 9 stressed also increasings, and when it was bent, blower fan just began to take place yaw maneuver, its crooked radian is big more, and the driftage angle is also big more.
