As a part at the top end of the generator set, the collecting ring can ensure the continuous rotation of the generator set and can also avoid the sprain of the lead in the rotation process of the generator set. The existing collecting ring comprises an insulating sleeve and a collecting ring plate arranged on the insulating sleeve, wherein the insulating sleeve comprises a sleeve and an insulating layer outside the sleeve.
At present, in the processing process of an insulating sleeve, after the processing of the sleeve is finished, a mold shown in fig. 1 is adopted to hot-press insulating gray cloth on the outer surface of the sleeve to form an insulating layer, the mold comprises a pressing ring 41 and a split pressing plate 43, when the insulating sleeve is used, a plurality of layers of insulating gray cloth are wrapped on the outer surface of the sleeve, then the sleeve wrapped with the insulating gray cloth is placed into the split pressing plate 43, after the inner surface of the split pressing plate 43 is tightly attached to the insulating gray cloth on the sleeve, the pressing ring 41 is used for pressing the split pressing plate 43, the split pressing plate 43 contracts inwards, and the insulating gray cloth is pressed to form the insulating layer; then the whole body which is communicated with the pressing ring 41, the split pressing plate 43 and the sleeve is placed in an oven for heating, so that the insulating layer is gelatinized and adhered to the sleeve; after heating and heat preservation for a certain period of time, the whole body is taken out, and then the pressing ring 41 is used again to apply pressure to the split pressing plate 43, so that the insulating layer is ensured to be firmly adhered to the sleeve. After the whole body is cooled, the sleeve needs to be taken out of the die and then the outer circle is machined so as to complete the whole machining process.
Because in the hydroelectric project, generator sets with different specifications are usually used, collecting rings with different sizes are also needed, and therefore insulating sleeves with different sizes need to be processed. However, since the size of the pressing ring 41 and the split pressing plate 43 of the mold in the prior art is fixed, the size of the machined sleeve is fixed. Therefore, in order to manufacture sleeves with different sizes, molds with various sizes need to be designed, and thus the manufacturing cost of the insulating sleeve is increased.

In this scheme, because the enclosed construction that compresses tightly the sleeve is that the concatenation of polylith flexbile plate forms, consequently when needs compress tightly not unidimensional sleeve, only need select the existing flexbile plate of appropriate quantity to splice in order to obtain the enclosed construction that matches with the sleeve size according to telescopic size, thereby the mode of adopting the mould of new dimension among the prior art has been replaced, compared with the prior art, in this scheme, the concatenation through the flexbile plate of different quantity can satisfy the use of multiple sleeve processing, thereby the suitability of mould has been improved, and monolithic flexbile plate obtains used repeatedly, can also reduce the processing cost of mould.
The first preferred scheme is as follows: preferably, the flexible plate is a flexible steel plate. Has the advantages that: consider that the flexbile plate need bear certain power of hugging closely when compressing tightly the insulating layer, just need the flexbile plate to have certain intensity, otherwise can take place the cracked condition of flexbile plate, telescopic processing just also can't go on smoothly, will influence insulating sleeve's processing cycle, consequently in this scheme, adopt flexible steel sheet then can guarantee to hug closely the power of hugging closely that the time needs bear to the going on smoothly of telescopic processing has been guaranteed.
The preferred scheme II is as follows: preferably, the flexible plate has a thickness of 2 mm. Has the advantages that: because when processing not unidimensional sleeve, in order to can laminate the sleeve surface, the bending degree of flexonics board can be different, just need the flexonics board to have certain rigidity, and if the rigidity of flexonics board is too big, then can't guarantee that the flexonics board can paste tightly with the sleeve surface, lead to insulating layer and sleeve can not paste tightly, the sleeve quality also can descend to some extent, therefore in this scheme, select the steel sheet that thickness is 2mm as the flexonics board, in order to guarantee can satisfy required rigidity requirement when processing different sleeves under the circumstances that possesses certain rigidity again, make the flexonics board can paste tight sleeve surface, thereby guarantee that the insulating layer after the processing can paste tight sleeve, thereby improve telescopic quality.
The preferable scheme is three: preferably as basic scheme, coupling assembling includes end plate and connecting piece, and the end plate is located the tip of flexbile plate and sets up perpendicularly with the flexbile plate, is provided with the connecting hole on the end plate, and the connecting piece can be dismantled with the connecting hole and be connected. Has the advantages that: in this scheme, utilize the setting of end plate and connecting piece to realize the connection of flexonics board, when two flexonics boards are connected to needs, fix after passing the connecting hole of two flexonics board upper end plates with the connecting piece to realize the connection of two end plates, just also realized the connection between two flexonics boards, and when the clearance between the flexonics board needs to be adjusted, only need change between two end plates the length of connecting piece can, simple structure.
The preferable scheme is four: preferably, in the third preferred embodiment, the connecting member is a bolt. Description of the drawings: the bolt in this scheme cooperation has the nut. Has the advantages that: in this scheme, after the selection bolt was as the connecting piece, when the clearance between two flexible sheets was adjusted to needs, only need twist the nut on the bolt, under the cooperation of bolt and nut, the end plate can remove along the bolt, and the clearance between two end plates just also can change easy operation.
