Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the sealed structure of aerogenerator of the present utility model and aerogenerator are further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the utility model, and it is not used in restriction the utility model.

Embodiment one

As shown in Figure 1, the gap of the sealed structure of a kind of aerogenerator for sealing between the stator module 1 of aerogenerator and engine room cover 2, the sealed structure of this aerogenerator comprises the first wear ring 3, the 2nd wear ring 4 and sealing-ring 5.

First wear ring 3 is fixedly connected on stator module 1, and the first wear ring 3 can comprise the first flange 32, first wear ring 3 and be fixedly connected on stator module 1 by the first flange 32, the assembling that can be convenient between the first wear ring 3 and stator module 1 like this. 2nd wear ring 4 is fixedly connected in engine room cover 2, and the 2nd wear ring 4 can comprise the 2nd flange the 42, two wear ring 4 and be fixedly connected in engine room cover 2 by the 2nd flange 42, the assembling that can be convenient between the 2nd wear ring 4 and engine room cover 2 like this.

It is adopt the 2nd flange 42 to be fitted in engine room cover 2 to carry out joining brill due to the connection hole of the 2nd flange 42 and the connection hole of engine room cover 2, and the material of engine room cover 2 all adopts glass reinforced plastic usually, so the material of the 2nd wear ring 4 can preferably adopt glass reinforced plastic, such 2nd wear ring 4 is identical with the material of engine room cover 2, that is the 2nd flange 42 is identical with the material of engine room cover 2, be conducive to the driller that joins in the connection hole between the 2nd flange 42 and engine room cover 2 to do, thus enable the connection hole of the 2nd flange 42 and the connection hole accurately correspondence of engine room cover 2.

First wear ring 3 comprises the first sealed end 31, first sealed end 31, and to have accommodation section 311, first sealed end 31 can be tubulose, and is connected on the first flange 32 by welding or other modes that are fixedly connected with that can realize. It can be cylindrical that 2nd wear ring 4 comprises the profile of the 2nd sealed end the 41, two sealed end 41, and is fixedly connected on the 2nd flange 42, and wherein the 2nd sealed end 41 and the 2nd flange 42 can one-body molded make.

2nd sealed end 41 is positioned at accommodation section 311 at least partly, and sealing-ring 5 is arranged on the 2nd sealed end 41, and is connected on the inwall of accommodation section 311. Jointly the gap between stator module 1 and engine room cover 2 is carried out positiver sealing by the first wear ring 3, sealing-ring 5 and the 2nd wear ring 4 like this, ensure that the resistance to air loss in cabin. The axis of stator module 1 and engine room cover 2 overlaps in actual applications, and and there is between horizontal plane the angle of 5 �� to 6 ��, the link position of such sealing-ring 5 and the 2nd sealed end 41 can higher than the link position between the 2nd sealed end 41 and the 2nd flange 42, rainwater can flow to the link position between the 2nd sealed end 41 and the 2nd flange 42 from the link position of sealing-ring 5 and the 2nd sealed end 41, can not be entered into the inside of generator by sealing-ring 5, sealing effect is very reliable.

When mounted, can first the first wear ring 3 and the 2nd wear ring 4 be fixedly connected in stator module 1 and engine room cover 2 respectively, again sealing-ring 5 is sleeved on the 2nd sealed end 41 of the 2nd wear ring 4, then the first wear ring 3 and the 2nd wear ring 4 correspondence are set with, relative to the installation carrying out tightness system in small space between generator and engine room cover in prior art, have and simplify installation process, it is to increase the advantage of operation convenience.

Specifically, the material of sealing-ring 5 is elastic organic material, such as rubber, urethane etc., can make that sealing-ring 5 is radial again has bigger draught like this, can compensate owing to central alignment deviation is relatively big between the first sealed end 31 and the 2nd sealed end 41, and the variable quantity of the sealing radial dimension of the sealing-ring 5 caused. It should be noted that, sealing-ring 5 is made into hollow, flexible to strengthen it.

As a kind of embodiment, the outer wall of the 2nd sealed end 41 is circumferentially provided with lug boss 411, circumferentially being provided with the first groove (not shown go out) mated with lug boss 411 phase on the inwall of sealing-ring 5, sealing-ring 5 is sleeved on lug boss 411 by the first groove. The stability connected between sealing-ring 5 and the 2nd sealed end 41 can be made so stronger, prevent sealing-ring 5 from displacement occurring relative to the 2nd sealed end 41 and affects sealing effect, the 2nd sealed end 41 and the 2nd flange 42 can also be made to form the cross-sectional shape of U shape simultaneously, namely circumferentially forming U shape groove on the surface of the 2nd wear ring 4, sleet, sand and dust can be drained from U shape groove.

Preferably, sealing-ring 5 is self-clamp type sealing-ring. Self-clamp type sealing-ring is not inventive point of the present utility model, but a kind of prior art, the utility model just make use of this prior art, it is not intended to make improvements, therefore the principle of work of self-clamp type sealing-ring no longer being described in detail, sealing-ring 5 adopts self-clamp type that the stability being connected between sealing-ring 5 with the 2nd sealed end 41 can be made to reach reinforcement further.

Embodiment two

The sealed structure of the aerogenerator described in the sealed structure of the aerogenerator in the present embodiment and embodiment has identical technology feature, difference is only, mode of connection between sealing-ring 5 and the 2nd sealed end 41 is different, as shown in Figure 2, circumferentially being provided with the 2nd groove (not shown go out) on the outer wall of the 2nd sealed end 41, sealing-ring 5 is arranged in the 2nd groove. It should be noted that, the 2nd sealed end 41 can also with embodiment one in identical, lug boss the 411, two groove having can circumferentially be arranged on the outer wall of lug boss 411.

Above embodiment only have expressed several enforcement mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model patent scope. , it is also possible to make some distortion and improvement, it should be appreciated that for the person of ordinary skill of the art, without departing from the concept of the premise utility these all belong to protection domain of the present utility model. Therefore, the protection domain of the utility model patent should be as the criterion with claims.
