Embodiment
Now the utility model embodiment is described in detail, its example shown in the accompanying drawings, wherein, identical label represents same parts all the time.
Below with reference to the accompanying drawings embodiment is described to explain the utility model.
Fig. 2 is the partial structurtes schematic diagram according to embodiment's of the present utility model wind-driven generator; Fig. 3 is the partial side view of having removed the wind-driven generator behind the impeller among Fig. 2.
As shown in Figures 2 and 3, in according to an embodiment of the present utility model, wind-driven generator comprises dead axle 5 and the rotating shaft 8 that is connected with impeller 9, at dead axle 5 generator unit stator 6 is installed, in rotating shaft 8 generator amature 7 is installed, generator amature 7 is around generator unit stator 6.When the wind-driven generator normal operation, rotate by the rotation drive rotating shaft 8 of impeller 9 upper blades, then drive generator amature 7 with respect to generator unit stator 6 rotations, thereby mechanical energy is converted to electric energy.
Wind-driven generator of the present utility model comprises at least two pitch wheels, that is, and and the first gear 12 and the second gear 11 that is meshed with the first gear 12.The first gear 12 is fixedly connected with rotating shaft 8.Specifically, further be fixedly connected with land 4 in the outer end of rotating shaft 8, this land 4 is circular, and the first gear 12 is fixedly connected on the outer surface of land 4.Yet the utility model is not limited to this, and the first gear 12 can be directly installed on the outer end of rotating shaft 8.When the second gear 11 stopped the rotation, the first gear 12 was owing to the meshing relation with the second gear 11 also can stop the rotation, and therefore, the second gear 11 is braked and just means that the first gear 12, rotating shaft 8 and impeller 9 are braked.The second gear 11 is connected with drive unit, and this drive unit can drive the second gear 11 and therewith rotate.That is, when this drive unit stopped operating, the second gear 11 also stopped operating; This drive unit can drive the second gear 11 and rotate when rotating.
Engagement system between the first gear 12 and the second gear 11 has two kinds, and a kind of is interior engagement, and another kind of is outer gearing.Specifically, when the engagement between two gears was interior engagement, the first gear 12 was internal gear, and the second gear 11 is external gear, that is, the second gear 11 is installed in the inboard of the first gear 12.When the engagement between two gears was outer gearing, the second gear 11 was installed in the outside of the first gear 12, and under this engagement system, the external diameter of the first gear 12 can be less than the external diameter of the second gear 11.Certainly, in the utility model, the engagement system between two gears is preferably interior engagement.
Drive unit can be in particular drive motor 10, and drive motor 10 is connected with the second gear 11.At drive motor 10 electromagnetic brake is installed, to realize the braking to the second gear 11.In addition, drive unit is not limited to drive motor 10, can also be motor etc.
Specifically, the second gear 11 can be installed on the output shaft of drive motor 10, thereby can be transmitted through the second gear 11 by the power of drive motor 10 outputs.Electromagnetic brake is installed on the output shaft of drive motor 10, by the braking to the output shaft of drive motor 10, thereby realizes braking to the second gear 11.
When needs are braked impeller 9, at first control drive unit, the second gear 11 is stopped operating.Specifically, can directly or by 10 pairs of electromagnetic brakes of drive motor switch on, so that the output shaft of electromagnetic brake braking drive motor 10, and then brake the second gear 11.When the second gear 11 stopped operating, the first gear 12 also stopped operating, and the simultaneously rotating shaft 8 of wind-driven generator is braked, the final braking that realizes impeller 9.
After impeller 9 brakings, the attendant just can safeguard wind-driven generator.
When needs carry out the jiggering operation to impeller 9, at first control drive unit, make it drive the second gear 11 and rotate.Specifically, can be directly or stop to the electromagnetic brake power supply by drive motor 10, make electromagnetic brake lose the function of braking, the rotation of drive motor 10 is sent on the second gear 11.When the second gear 11 rotates, drive the first gear 12 and rotate, impeller 9 is rotated then.When impeller 9 turns to default position, again control drive unit, it is stopped operating, the second gear 11 also stops operating simultaneously, and impeller 9 is braked in this position.That is, can directly or by drive motor 10 switch on to electromagnetic brake, thereby the quick and stable braking of the second gear 11 is achieved.
Need to prove, in above-mentioned jiggering process, because the weight of impeller 9 is larger, and the rotating speed of drive motor 10 is relatively high, in rotating the process of transmitting, preferably it is slowed down and increase square, so that the rotation relatively high and the power less of drive motor 10 rotating speeds is converted to the rotation that rotating speed is relatively low and power is relatively large.For this reason, can realize above-mentioned purpose by further connection reducer 13 between drive motor 10 and the second gear 11.That is, the output shaft of this retarder 13 is connected with the second gear 11, and the input shaft of retarder 13 is connected with drive motor 10.Like this, on the one hand, retarder 13 can not affect the normal brake application of impeller 9, and simultaneously when impeller 9 jiggering, can play slows down increases the effect of square, realizing easily the jiggering to impeller 9, thereby can make impeller 9 be parked in more exactly the precalculated position.
In addition, if the external diameter of the second gear 11, also can play certain deceleration less than the external diameter of the first gear 12 and increase the square effect.
In above-mentioned braking and jiggering process, by to drive unit control and two gears between intermeshing effect, replaced friction catch of the prior art, braking function is reliable and stable.In addition, also can realize the accurate location of impeller 9 is braked according to wind-driven generator of the present utility model, thereby can with impeller 9 jiggerings to the position of setting arbitrarily, carry out upkeep operation to maintain easily personnel to wind-driven generator.
In according to another embodiment of the present utility model, wind-driven generator can further comprise two the second gears 11, can also respectively be connected with a retarder 13 and drive motor 10 on each second gear 11.Specifically, can all adopt interior engagement to transmit between the first gear 12 and two the second gears 11, and two the second gears 11 can be oppositely arranged, as be arranged on the up and down two ends of the first gear 12.Like this, in the identical situation of the rotating speed of impeller 9, by increasing the area of contact between the gear, the braking force that each second gear 11 bears in the time of can significantly being reduced in braking is to improve the working life of two gears.
Yet the utility model is not limited to this, can also between the first gear 12 and the second gear 11 other gears being set further, be sent to the first gear 12 with the motion with the second gear 11; Also can between the second gear 11 and drive unit, gear be set.More gear can also be set in other positions, can control by the gear engagement rotation of the first gear 12 as long as can guarantee drive unit.
The above describes in detail wind-driven generator provided by the utility model.Although represented and described embodiments more of the present utility model; but those skilled in the art should understand that; in the situation that does not break away from the principle of the present utility model that limited its scope by claim and equivalent thereof and spirit; can make amendment and perfect to these embodiments these modifications and improve also should be in protection domain of the present utility model.
