Technical field
The utility model relates to a kind of wind-driven generator, and particularly a kind of small-sized stepless speed change type is from the speed-regulating wind power generation machine.
Background technique
There is following problem in small-sized wind power generator at present: 1) traditional small-sized wind power generator velocity ratio is constant, start wind speed constant, when the wind speed in environment is less than the minimum wind speed that makes the air blade running, generator does not rotate and does not generate electricity, and this has just wasted this part energy.2) the general use of traditional small-sized wind power generator is the speeder (gear-box) of constant gear ratio, and when wind-force is unstable, the input speed of generator can change a lot, and this can cause, and the motor feels hot increases, and lowers efficiency, causes loss.And impeller lateral-deviation type speed regulating mechanism easily causes the swing of wind wheel and empennage when wind speed and direction changes greatly, thereby cause the vibration of wind energy conversion system.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of small-sized stepless speed change type from the speed-regulating wind power generation machine.
Its technological scheme is: comprise blade, gear, belt, buncher driving wheel, controller, generator, speed probe, buncher follower, described blade pass is crossed gear and is connected with the buncher driving wheel, the buncher driving wheel is controlled stepless speed variator by controller and is changed velocity ratio, described buncher driving wheel is connected to the buncher follower by belt, one side of buncher follower is provided with speed probe, and the output shaft of buncher follower is connected to generator.
Be provided with the driving wheel knob between above-mentioned buncher driving wheel and controller, speed probe is measured the rotating speed of generator shaft, then signal is passed to controller, and controller is compared input signal with setting value, then control the driving wheel knob, thereby control the velocity ratio of stepless speed variator.
The beneficial effects of the utility model are: increased application area, improved wind energy utilization; Motor speed remains near rated speed, realizes transient equiliblium, has reduced loss, has improved the working life of wind-driven generator.Substantive technical characterstic remarkable result with energy-saving and emission-reduction.

Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: blade 1, gear 2, belt 3, buncher driving wheel 4, driving wheel knob 5, controller 6, generator 7, speed probe 8, buncher follower 9.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises blade 1, gear 2, belt 3, buncher driving wheel 4, controller 6, generator 7, speed probe 8, buncher follower 9, described blade 1 is connected with buncher driving wheel 4 by gear 2, buncher driving wheel 4 is controlled stepless speed variator by controller 6 and is changed velocity ratio, described buncher driving wheel 4 is connected to buncher follower 9 by belt 3, one side of buncher follower 9 is provided with speed probe 8, and the output shaft of buncher follower 9 is connected to generator 7; Be provided with driving wheel knob 5 between above-mentioned buncher driving wheel 4 and controller 6.
By the spacing that hangs over the speed belt on belt pulley, change, the spacing of mechanical side speed pulley also and then changes, and is the belt type adjustable speed drive that can freely change rotating speed.In the course of the work, speed probe constantly gathers the rotating speed of generator, then with rated speed, compares, according to the velocity ratio of output control stepless speed variator relatively.The precision of controlling depends on that sensor gathers the frequency of rotating speed and the fastest ratio that stepless speed variator can change.
Small-sized stepless speed change type has following characteristics from the speed governing high-efficiency wind driven generator:
1) transmission ratio-variable, the blade detent torque is variable, the generating of also can turning round of very low wind speed, and the rated speed that starts wind speed and actual power can be different, so just reduced detent torque, wind-driven generator can slowly start when low wind speed, then is transitioned into gradually high rotating speed, reduced detent torque, it is more easy to make to start.
2) in complicated wind field, ceaselessly change velocity ratio by feedback, motor speed is remained near rated speed, realize transient equiliblium, reduced loss, improved wind energy utilization.
3) when wind speed is excessive, with traditional brake deceleration, compare, we adopt the method that increases velocity ratio to allow motor keep best generating state, have improved utilization ratio.
4) with impeller lateral-deviation type mode of speed regulation, compare, this gear shift mode can not cause vibration, more steadily reliable.
