Contact modules, which are realized, to be relatively rotated, and slip ring unitary rotation is realized by slip ring upper/lower terminal bearing；And the slip ring include oil inlet with
Oil outlet, methods for cooling use immersion oil mode.This above-mentioned slip ring transfers high-voltage great-current due to needing to meet under specific dimensions
Requirement, it is therefore necessary to use internal immersion oil form.
Immersion oil inside slip ring, what slip-ring rotor leaked out in rotation process there may be a small amount of fluid from dynamic sealing
Situation.Under longtime running, if be not collected to the fluid of leakage, it will pollution outside plant.
The content of the invention
It is an object of the invention to provide a kind of leakage fluid of oil-immersed type slip ring from collection device, so as to efficiently and easily
It realizes the collection of waste oil, avoids pollution outside plant.
Realize the object of the invention technical solution be：A kind of leakage fluid of oil-immersed type slip ring is from collection device, institute
The dynamic lid inner ring for stating oil-immersed type slip ring is connected by clutch shaft bearing with slip ring main shaft, and inner end cap is set above the link position, interior
End cap is labyrinth structure with dynamic lid link position；Dynamic lid outer ring is connected by second bearing with outer barrel, is set above the link position
Outer end cap is put, outer end cap is labyrinth structure with outer barrel link position；
The dynamic labyrinth structure covered is in a high position compared with the labyrinth structure on outer barrel, using the dynamic labyrinth structure covered as
The oil trap of inner ring, labyrinth structure on outer barrel set oil guide pipe to realize oil as outer ring oil trap between inside and outside circle oil trap
Road connects, and the long-pending oil of inner ring oil trap is spontaneous under the effect of gravity to flow to outer ring maze trough via oil guide pipe and valve block, then passes through
The oil exit pipe of outer ring oil-collecting trench bottom connection all collects waste oil to waste oil collecting tank.
As a kind of specific example, the first static seal, clutch shaft bearing are set between the clutch shaft bearing and slip ring main shaft
Second static seal between dynamic lid is set, the first dynamic seal is set between stationary part and rotating part in clutch shaft bearing.
As a kind of specific example, the 3rd static seal is set between the second bearing and dynamic lid, second bearing with it is outer
5th static seal between cylinder is set, moves and the 4th static seal is set between lid and outer end cap, in second bearing stationary part with
Second dynamic seal is set between rotating part.
As a kind of specific example, the dynamic lid is connected by second bearing with supporting rack.
Compared with prior art, the present invention its remarkable advantage is：(1) company between dynamic sealing maze trough inside and outside rotor is passed through
It connects, the fluid that slip ring inner ring dynamic sealing is leaked is dredged to the dynamic sealing maze trough of outer ring, then by the maze trough of outer ring
It connects oil exit pipe all to collect the long-pending oil of outer ring to waste oil collecting tank, realizes the collection of waste oil, avoids pollution is external from setting
It applies；(2) only need to one collecting tank be set in slip ring outer wall features simple structure is reliable, at low cost with regard to that can complete the function of waste oil collecting；
(3) collecting certainly for waste oil is realized, power is provided without the external world.
Description of the drawings
Fig. 1 is leakage structure diagram of the fluid from collection device of oil-immersed type slip ring of the present invention.
Fig. 2 is the structure diagram of leakage fluid outer barrel from collection device of oil-immersed type slip ring of the present invention.
Fig. 3 is that the leakage fluid of oil-immersed type slip ring of the present invention moves the structure diagram of lid from collection device.
Specific embodiment
With reference to Fig. 1~3, the leakage fluid of oil-immersed type slip ring of the present invention is from collection device, the dynamic lid 4 of the oil-immersed type slip ring
Inner ring is connected by clutch shaft bearing 7 with slip ring main shaft 1, and inner end cap 5 is set above the link position, and inner end cap 5 is connected with dynamic lid 4
Position is labyrinth structure；Dynamic 4 outer ring of lid is connected by second bearing 8 with outer barrel 3, outer end cap 6 is set above the link position, outside
End cap 6 is labyrinth structure with 3 link position of outer barrel；
Labyrinth structure on dynamic lid 4 is in a high position compared with the labyrinth structure on outer barrel 3, by the labyrinth structure on dynamic lid 4
As the oil trap of inner ring, labyrinth structure on outer barrel 3 sets oil guide pipe as outer ring oil trap between inside and outside circle oil trap
16 realize oil circuit connection, and the long-pending oil of inner ring oil trap is spontaneous under the effect of gravity to flow to outer ring fan via oil guide pipe 16 and valve block 17
Palace slot, then all collected waste oil to waste oil collecting tank 19 by the oil exit pipe 18 that oil-collecting trench bottom in outer ring connects.Valve block 17 is used
It transfers, realizes the connection of oil pipe 16 and outer end cap 6.
As a kind of specific example, the first static seal 9, first axle are set between the clutch shaft bearing 7 and slip ring main shaft 1
It holds and the second static seal 11 is set between 7 and dynamic lid 4, set first to move between stationary part and rotating part in clutch shaft bearing 7
Sealing element 10.
As a kind of specific example, the 3rd static seal 12, second bearing 8 are set between the second bearing 8 and dynamic lid 4
5th static seal 15 between outer barrel 3 is set, moves and the 4th static seal 13, second bearing 8 is set between lid 4 and outer end cap 6
Second dynamic seal 14 is set between middle stationary part and rotating part.
With reference to Fig. 3, the dynamic lid 4 is connected by second bearing 8 with supporting rack 2.
The leakage oil collection principle of leakage fluid from the collection device of oil-immersed type slip ring of the present invention is as follows：
When dynamic lid 4 rotates, oil may on a small quantity be oozed by the first dynamic seal 10 and the second dynamic seal 14 inside slip ring
Go out.Since there are the first static seal 9 and the second static seal 11, the oil oozed out from the first dynamic seal 10 can flow to dynamic lid
In maze trough on 4.Due to there are the 3rd static seal 12, the 4th static seal 13 and the 5th static seal 15, being moved from second
The oil that sealing element 14 oozes out can be flowed in the maze trough on outer barrel 3.
Oil guide pipe 16 is connected between above-mentioned two maze trough.Since inner ring maze trough is in a high position, the long-pending oil of the inside can be
It is spontaneous under gravity to flow to outer ring maze trough via oil guide pipe 16 and valve block 17.In outer ring maze trough lower openings, and connect
Oil exit pipe 18.Long-pending oil in the maze trough of outer ring is flow to by oil exit pipe 18 in waste oil collecting tank 19 again.It is achieved in the receipts of oil leak
Collection.
In conclusion the present invention only need to set a collecting tank with regard to that can complete the function of waste oil collecting in slip ring outer wall, tool
There is the advantages of features simple structure is reliable, at low cost.
