A set of braking system is respectively arranged on the high-speed shaft and the low-speed shaft according to the problem of the existing wind driven generator braking system by combining the braking process of a windmill, and the utility model reduces the impact on a gear case and prolongs the service life of the gear case via the opening and closing states of the two sets of braking systems under different conditions.
Description
Technical field
The utility model relates to a kind of wind-driven generator brake system, relates in particular to a kind of wind-driven generator brake system of intelligent control.
Background technique
Brake system is a very important system in the wind-driven generator, and its significance should be higher than other system in logic, and this just requires brake system to have very high Security and reliability.
The blower fan brake system is divided into wind-force brake system and mechanical brake system, and the brake of mechanical brake system generally loads on high speed shaft or the lower velocity shaft.Because the emergency shutdown that dead halt and accident cause; require blower fan to stop in the shortest time, this moment, the wind-force brake dropped into simultaneously with mechanical brake, if mechanical brake just loads on the lower velocity shaft; then, require the size of brake and brake torque big because the torque on the lower velocity shaft is bigger.Size is big, just installs and has problem, and moment is big, and is just high to the requirement of hydraulic system and sealing, loads the impact that will cause on the high speed shaft gear-box, the damage of accelerating gearbox.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of wind-driven generator brake system of intelligent control, and purpose is for blower fan being shut down and reducing impact to gear-box.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of wind-driven generator brake system of intelligent control, its structure is as follows: fan blade is installed on the lower velocity shaft, lower velocity shaft is provided with lower velocity shaft brake and lower velocity shaft speed probe, lower velocity shaft is connected with gearbox, one end of high speed shaft is connected with gearbox, high speed shaft is provided with high speed shaft speed probe and high speed shaft brake, the other end of high speed shaft is connected with wind-driven generator, and lower velocity shaft brake, lower velocity shaft speed probe, high speed shaft speed probe and high speed shaft brake are connected with control mechanism.
Described lower velocity shaft speed probe and high speed shaft speed probe are hall sensing formula sensor.
Described control mechanism is a single-chip microcomputer.
Owing to adopt technique scheme, make to the utlity model has following advantage and effect:
The problem that the utility model exists according to existing wind-driven generator brake system, while is in conjunction with the skidding process of windmill, respectively adorning a cover brake system at a high speed with on the lower velocity shaft, by the open and close state of two cover brake system under different situations, reduce impact, prolong the gear-box life-span gear-box.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, fan blade; 2, lower velocity shaft; 3, lower velocity shaft brake; 4, lower velocity shaft speed probe; 5, gearbox; 6, high speed shaft; 7, high speed shaft speed probe; 8, high speed shaft brake; 9, wind-driven generator.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the wind-driven generator brake system of the utility model intelligent control, structure is as follows: fan blade 1 is installed on the lower velocity shaft 2, lower velocity shaft 2 is provided with lower velocity shaft brake 3 and lower velocity shaft speed probe 4, lower velocity shaft 2 is connected with gearbox 5, one end of high speed shaft 6 is connected with gearbox 5, high speed shaft 6 is provided with high speed shaft speed probe 7 and high speed shaft brake 8, the other end of high speed shaft 6 is connected with wind-driven generator 9, and lower velocity shaft brake 3, lower velocity shaft speed probe 4, high speed shaft speed probe 7 and high speed shaft brake 8 are connected with control mechanism.Control mechanism is a single-chip microcomputer.
The utility model improves on the basis of wind-driven generator original system, on lower velocity shaft and high speed shaft, add a cover brake respectively, respectively add a cover speed probe simultaneously, hall sensing formula transducer sensitivity height, the induction speed range is big, so adopt this speed probe.Brake on the lower velocity shaft only plays the auxiliary brake effect, and size and brake torque do not need very big, and this has just avoided its shortcoming.Because the auxiliary brake effect of brake on the lower velocity shaft is arranged, the brake brake of high speed shaft just can not cause too big inertia impact to gear-box, has reduced the damage of gear-box, has prolonged the life-span of gear-box, has shortened the brake time simultaneously yet.
