Description
(1) technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of middle-size and small-size vertical shaft, horizontal axis wind-driven generator centrifugal wheel intelligent speed reducing device, is used for wind speed and wind-driven generator is slowed down when excessive.
(2) background technique
Along with the arrival of energy crisis, green energy resource has obtained attention and application more and more widely, and in this respect, wind-power electricity generation has obtained fairly large application as renewable green energy resource.Yet, in the wind-power electricity generation process, exist a puzzlement people's a difficult problem: surpassing under the wind speed setting environment, because wind-force is excessive, rotation speed of fan is too high, causes the overtension that produces, too high voltage causes electronic parts and components such as diode, triode to damage easily, even can burn out transformer coil, the electricity that makes blower fan send can't store, and causes generator efficiency to descend; Also exist simultaneously potential safety hazard, when high wind speed causes the fan blade rotating speed too fast, because the instability of fan blade windward side, make the blower fan tail vane lose function, the positive force direction that is subjected to that is offset wind of fan blade fan blade can not be facingd the wind and work, if can produce reaction force to fan blade, it is fractureed from falling down in the air, will cause serious security incident.
For overcoming above-mentioned shortcoming, at present, reequiping aspect the electrical equipment control of motor usually, common way is to strengthen resistance off-load discharge, but, in the process that solves, also can put if control the electricity that inappropriate meeting causes laying in storage battery, can damage storage battery after long-term the use, simultaneously, after element volume such as resistance strengthen, not only will increase the cost of blower fan, and under normal wind speed, produce big power loss, reduced generating efficiency; Simultaneously also non insurance under the thunderbolt situation causes that when line short had a power failure, wind-driven generator can't be carried out control under situation about having a power failure, burn out motor easily in case meet the weather that thunders.In addition, also there is manufacturer to adopt the change oar principle of mechanical aspects, adds small motor, retarder and reduction gear etc. at the root of each fan blade, but this type of mode is complex structure not only, and operate when needing electrical equipment and manual interlocking, inefficiency can't realize intelligent the deceleration.
(3) model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of intellectuality and middle-size and small-size vertical shaft, horizontal axis wind-driven generator centrifugal wheel intelligent speed reducing device with low cost are provided.
The purpose of this utility model is achieved in that a kind of middle-size and small-size vertical shaft, horizontal axis wind-driven generator centrifugal wheel intelligent speed reducing device, include the track fixed base, the pulley frame track, spring, fixed pulley and motor, described track fixed base is provided with some groups of pulley frame tracks, every group by two pulley frame tracks compositions, described pulley frame track is provided with baffle plate away from track fixed base one end, all be set with pulley frame on every group of pulley frame track, described spring housing is loaded on the pulley frame track, and spring one end contacts with pulley frame, the other end contacts with baffle plate, the top of described pulley frame is provided with a pulley, described fixed pulley matches with pulley, and described fixed pulley is installed on the electric motor end cap of motor.
The middle-size and small-size vertical shaft of the utility model, horizontal axis wind-driven generator centrifugal wheel intelligent speed reducing device, described track fixed seating is loaded on the motor shaft of motor, and described track fixed base is connected with motor shaft by flat key.
The middle-size and small-size vertical shaft of the utility model, horizontal axis wind-driven generator centrifugal wheel intelligent speed reducing device, described pulley frame track is fixed on the track fixed base by tightening nut.
Working principle of the present utility model is:
Increase along with wind-force, centrifugal force strengthens gradually, pulley is along with pulley frame moves to fixed pulley, until bump momentum law F Δ t=m Δ V during according to collision with fixed pulley, when wherein F takes place for collision, the impact force that pulley is suffered, the direction of this power on the circle center line connecting of pulley and fixed pulley, and with the pulley direction of rotation, m is the quality of pulley as shown in Figure 4, the change amount of pulley speed before and after Δ V bumps; Simultaneously, pulley is with after fixed pulley contacts, exist a frictional force f opposite simultaneously with the pulley motion direction, F can decomposite F1 and the f1 opposite with the pulley motion direction respectively with f, rotation to pulley plays inhibition, when wind speed increases, when rotation speed of fan increases, drive the increase of pulley rotating speed, when making the collision of pulley and fixed pulley, rapid change amount Δ V before and after the pulley collision increases, because relative velocity is very fast, causes time of collision Δ t also shorter simultaneously, thereby F=m Δ V/ Δ t will increase greatly, corresponding F1 also increases greatly, increases the inhibition to pulley, will make the rotating speed of blower fan descend; The rear wheel rotating speed strengthens in addition, and the surface of contact of pulley and fast pulley strengthens, and the also corresponding increasing of the frictional force that is produced, thereby also increase accordingly of f1 are to also decline effect of rotation speed of fan.So after rotation speed of fan increased, reducing motor was also big more to the inhibition of blower fan, also just can faster rotation speed of fan be reduced.And in case after fan blade rotating speed reduction, the elastic force of spring separates the blower fan proper functioning with the pulley original position of rebounding with fixed pulley.
The beneficial effects of the utility model are:
Use simple, only need the track fixed seating is contained on the motor shaft of motor, and fix by flat key, have only when wind speed surpasses certain speed, pulley just contacts with fixed pulley and works, all the other time blower fan work are unaffected, thereby do not need artificially it to be controlled, and have intelligentized effect; And with respect to original electrical equipment control or the control of machinery change slurry, structure is more simple, has reduced its manufacture cost, has improved utilization ratio of wind energy, and simultaneously in use, the motor of vertical shaft or horizontal axis all can be installed, and using scope is wide.
