Description

Utilize the wind-driven generator flywheel engaging and disengaging gear of train travel wind
Technical field
The utility model relates to a kind of wind-driven generator flywheel engaging and disengaging gear that utilizes train travel wind.
Background technique
After train crosses,, not only cause the fluctuation of the magnitude of voltage of sending out, cause the damage of wind generator device when serious because the effect of driving wind causes wind turbines rotor and rotating speed that violent impact is all arranged.Generally; Often take simple and easy engaging and disengaging gear to break off the axle dockingundocking of wind wheel and generator; Though this method avoids motor to damage because of hypervelocity, the same fluctuation of output voltage is bigger, simultaneously; Wind turbines rotor and then impacts whole system because underloading often significantly reduces in the back that runs up working life.
Summary of the invention
For overcoming above-mentioned deficiency, a solution is provided, the wind-driven generator rotating shaft is provided with the flywheel engaging and disengaging gear; The wind-driven generator rotating shaft can be divided into rotating shaft A section part and rotating shaft B section part, on rotating shaft A section, is provided with groove, and clutch is connected with groove; Rotating shaft A section is provided with electromagnet, and electromagnet core is connected with spring, and rotating shaft A section is connected with bearing A; The flywheel engaging and disengaging gear is provided with the reinforcing shell, bearing B and reinforcing shell mechanical connection, and flywheel is connected with bearing A, bearing B respectively; Reinforce shell inner laser tachometer and be electrically connected with feedback control, rotating shaft B section is provided with rotating disk, and brush is accomplished with electromagnet and is electrically connected, and motor output shaft is connected with rotating shaft B section.
When speed probe detects wind speed when low, send instruction by feedback control, electromagnet releasing clutch, clutch under spring action and divided flywheel leave the wind-driven generator light running; When speed detection unit detects wind speed when higher, electromagnetic actuation clutch, clutch and flywheel combine and rotate with rotating shaft; The wind-driven generator load operating; When speed probe detects rotating speed by high step-down, send instruction by feedback control, clutch and flywheel time-delay are separately; The kinetic energy of laying on the flywheel slowly discharges, and keeps the stationarity of rotating speed.
This flywheel engaging and disengaging gear is applicable to horizontal shaft type wind-driven generator and perpendicular axis type formula wind-driven generator.The beneficial effect of the utility model is the stationarity that keeps rotating speed, avoids the fluctuation of the magnitude of voltage of sending out, and simultaneously equipment is also played a protective role.
