Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a maintenance device for wind turbine slip rings. Background Technology

[0002] According to the patent document with publication number CN216958812U, when cleaning and maintaining the slip ring, the slides of the slip ring are cleaned one by one with cotton swabs. After all the slides are cleaned, lubricant is dripped into each slide to lubricate it. The patent document states that when cleaning slip rings, different types of slip rings have different track sizes. Therefore, for narrower tracks, cleaning with cotton swabs may not clean the corners of the track thoroughly. Also, some cotton fibers may be left inside the slip ring during cleaning, resulting in foreign objects remaining on the track. Furthermore, for some slip rings with multiple tracks, cleaning with cotton swabs is slow and time-consuming, affecting the use of the slip ring. Utility Model Content

[0003] The purpose of this invention is to provide a maintenance device for fan slip rings in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions: A maintenance device for a fan slip ring includes a slip ring body, a support frame on the upper side of the slip ring body, two moving mechanisms inside the support frame, a supply mechanism on the front side of the support frame, and two clamping mechanisms located inside the two moving mechanisms respectively. Each clamping mechanism is equipped with a flushing mechanism. The rinsing mechanism includes an arc-shaped cover with a spray hole on the side of the arc-shaped cover facing the slip ring body. An inlet pipe is fixed at the upper end of the arc-shaped cover, and an actuating ring is fixed on the upper side of the inlet pipe. An actuating plate is provided on the side of the actuating ring close to the slip ring body. An annular groove is provided on the upper side of the inlet pipe, and two symmetrical lugs are fixed in the annular groove. The clamping mechanism includes a clamping frame, a locking frame on one side of the clamping frame, and the clamping frame and the locking frame are fixedly connected by a clamping spring. The end of the clamping frame and the locking frame away from the moving mechanism is provided with a semi-circular notch, and the inner wall of the notch is provided with an arc-shaped groove. Each arc-shaped groove is provided with a return spring.

[0005] Preferably, the moving mechanism includes two sliding frames, which are slidably connected to both ends of the slip ring body. A guide rod is fixed between the two sliding frames, and a threaded rod is provided on the lower side of the guide rod. Both ends of the threaded rod are rotatably connected to the two sliding frames, and a drive motor is fixedly provided at the input end of the threaded rod.

[0006] Preferably, the two ends of the actuating plate are fixed to the lower ends of the two sliding frames, and the lower side of the clamping frame is provided with a threaded hole for cooperating with the threaded rod.

[0007] Preferably, the actuating plate has a tooth on the side near the actuating ring, and the actuating ring has a fixed actuating plate near the actuating plate.

[0008] Preferably, the ends of the two return springs that are far apart from each other are fixed at the two ends of the arc-shaped groove, and the ends of the two return springs that are close to each other are located on the front and rear sides of the support lug.

[0009] Preferably, both the clamping frame and the locking frame have sliding holes on their upper sides for sliding on the guide rod, and the clamping spring is sleeved on the outside of the guide rod.

[0010] Preferably, the supply mechanism includes a cleaning liquid tank, with an air inlet pipe and a supply pipe fixed at the upper end of the cleaning liquid tank.

The liquid outlet of the supply pipe is provided with a branch pipe, and the other two ends of the branch pipe are connected to the upper ends of the two liquid inlet pipes.

[0011] The advantages compared to existing technologies are as follows: The moving mechanism drives the clamping frame to move the inlet pipe along the toggle plate to both sides. At this time, the movement of the inlet pipe will cause the toggle ring to slide across the toggle plate in a wave-like manner, thereby causing the inlet pipe to rotate on its own axis. At the same time, the two return springs on the locking frame and the clamping frame will cause the inlet pipe to return to its original position in the opposite direction. Then, the inlet pipe and the arc-shaped cover will reciprocate and rotate alternately, which will then swing and flush the slide of the slip ring body, thereby washing away any carbon powder or debris that may be attached to the slide. In addition, the slip ring body can be continuously cleaned by supplying compressed air to facilitate the application of lubricating oil. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8 As shown, a maintenance device for a fan slip ring includes a slip ring body 5, a support frame 6 on the upper side of the slip ring body 5, two moving mechanisms 1 inside the support frame 6, a supply mechanism 3 on the front side of the support frame 6, and two clamping mechanisms 2, which are respectively located inside the two moving mechanisms 1. Each clamping mechanism 2 is provided with a flushing mechanism 4. In this embodiment: the moving mechanism 1 includes two sliding frames 11, which are slidably connected to both ends of the slip ring body 5. A guide rod 12 is fixed between the two sliding frames 11. A threaded rod 13 is provided on the lower side of the guide rod 12. Both ends of the threaded rod 13 are rotatably connected to the two sliding frames 11. A drive motor 14 is fixedly provided at the input end of the threaded rod 13. The rotating part of the drive motor 14 drives the threaded rod 13 to rotate on the lower side of the two sliding frames 11. The rotation of the threaded rod 13 drives the clamping mechanism 2 to move to both sides. At the same time, the guide rod 12 provides auxiliary support for the clamping mechanism 2. In addition, by moving the two sliding frames 11, the slip ring body 5 of different sizes can be maintained and cleaned.

[0017] In this embodiment: the rinsing mechanism 4 includes an arc-shaped cover 42. The arc-shaped cover 42 has a spray hole on the side facing the slip ring body 5. An inlet pipe 41 is fixed to the upper end of the arc-shaped cover 42. An actuating ring 43 is fixed to the upper side of the inlet pipe 41. An actuating plate 45 is provided on the side of the actuating ring 43 near the slip ring body 5. An annular groove is provided on the upper side of the inlet pipe 41, and two symmetrical lugs 44 are fixed in the annular groove. The two ends of the actuating plate 45 are fixed to the lower ends of two sliding frames 11. A threaded hole for cooperating with the threaded rod 13 is provided on the lower side of the clamping frame 21. A tooth is provided on the side of the actuating plate 45 near the actuating ring 43. A actuating plate is fixed on the position of the actuating ring 43 near the actuating plate 45. The cleaning fluid to be injected into the arc-shaped cover 42 is delivered by the inlet pipe 41, and the cleaning fluid is continuously propelled by the pressure of compressed air. The cleaning fluid sprayed from the spray holes of the arc-shaped cover 42 will flush the slide of the slip ring body 5, thereby washing away any carbon powder or debris that may be attached to the slide. In addition, the rotation of the threaded rod 13 drives the clamping mechanism 2 to move the inlet pipe 41 along the actuating plate 45. When the inlet pipe 41 moves, the actuating teeth of the actuating plate 45 will push the actuating ring 43 to rotate around the axis of the inlet pipe 41 at a certain angle. When the actuating ring 43 rotates, it will also drive the inlet pipe 41 to rotate synchronously. Then, the clamping mechanism 2 will cause the inlet pipe 41 to flip back and reset. Then, during the movement of the inlet pipe 41, the slide of the slip ring body 5 will be flushed by reciprocating swing. In addition, when flushing the slide of the slip ring body 5, different positions of the slide can be completely flushed by rotating the slip ring body 5.

[0018] In this embodiment: the clamping mechanism 2 includes a clamping frame 21, and a locking frame 22 is provided on one side of the clamping frame 21. The clamping frame 21 and the locking frame 22 are fixedly connected by a clamping spring 24. The ends of the clamping frame 21 and the locking frame 22 away from the moving mechanism 1 are each provided with a semi-circular notch, and the inner wall of the notch is provided with an arc-shaped groove. Each arc-shaped groove is provided with a return spring 23. The ends of the two return springs 23 away from each other are respectively fixed to the two ends of the arc-shaped groove, and the ends of the two return springs 23 close to each other are respectively located on the front and rear sides of the lug 44. The upper side of the clamping frame 21 and the locking frame 22 are provided with a clamping spring 24 for the guide rod 1. The sliding hole on the guide rod 12 has a clamping spring 24 sleeved on the outside of the guide rod 12. The clamping spring 24 drives the locking frame 22 to move along the threaded rod 13 towards the clamping frame 21. At this time, the notch of the locking frame 22 and the notch of the clamping frame 21 are inserted into the annular groove of the liquid inlet pipe 41. At the same time, the two lugs 44 in the annular groove of the liquid inlet pipe 41 are respectively inserted into the arc groove of the clamping frame 21 and the locking frame 22. The two lugs 44 are respectively located between the two return springs 23 of the clamping frame 21 and the two return springs 23 of the locking frame 22. Then the liquid inlet pipe 41 is supported by the locking frame 22 and the clamping frame 21.

[0019] In this embodiment: the supply mechanism 3 includes a cleaning fluid tank 31. An air inlet pipe 32 and a supply pipe 33 are fixed at the upper end of the cleaning fluid tank 31. The air outlet of the air inlet pipe 32 extends into the upper side of the liquid surface inside the cleaning fluid tank 31, and the liquid inlet of the supply pipe 33 extends into the lower side of the liquid surface inside the cleaning fluid tank 31. The liquid outlet of the supply pipe 33 is provided with a branch pipe 34. The other two ends of the branch pipe 34 are connected to the upper ends of two inlet pipes 41. By sending clean compressed air into the air inlet of the air inlet pipe 32, the cleaning fluid inside the cleaning fluid tank 31 is guided to the two inlet pipes 41 through the supply pipe 33 and the branch pipe 34. Then, the cleaning fluid is sprayed out from the spray hole of the arc-shaped cover 42 through the two inlet pipes 41 to rinse the slide of the slip ring body 5.

[0020] Working principle: In use, first, place the two inlet pipes 41 on the front and rear sides of the slip ring body 5. Then, place the arc-shaped groove on the upper side of the inlet pipe 41 between the recess of the clamping frame 21 and the locking frame 22. Then, use the clamping spring 24 to drive the locking frame 22 to move along the threaded rod 13 towards the clamping frame 21. At this time, the recess of the locking frame 22 and the recess of the clamping frame 21 are engaged in the annular groove of the inlet pipe 41. At the same time, the two lugs 44 in the annular groove of the inlet pipe 41 are engaged in the arc-shaped grooves of the clamping frame 21 and the locking frame 22, respectively. The two lugs 44 are located on the two return springs 23 of the clamping frame 21 and the locking frame, respectively. Between the two return springs 23 of 22, the inlet pipe 41 is supported by the locking bracket 22 and the clamping bracket 21. At this time, the rotating part of the drive motor 14 drives the threaded rod 13 to rotate under the two sliding brackets 11. The rotation of the threaded rod 13 drives the clamping mechanism 2 to move to both sides. At the same time, the guide rod 12 provides auxiliary support for the clamping mechanism 2. In addition, by moving the two sliding brackets 11, the slip ring bodies 5 of different sizes can be maintained and cleaned. Then, clean compressed air is sent into the air inlet end of the air inlet pipe 32, so that the cleaning fluid in the cleaning fluid tank 31 is guided to the two inlet pipes through the supply pipe 33 and the branch pipe 34. Inside the tube 41, the cleaning fluid is fed into the arc-shaped cover 42 via the inlet tube 41. Compressed air pressure forces the cleaning fluid to continuously spray from the spray holes of the arc-shaped cover 42. This sprayed cleaning fluid flushes the slide rails of the slip ring body 5, removing any carbon powder or debris that may be adhering to the slide rails. Furthermore, the rotation of the threaded rod 13 drives the clamping mechanism 2, causing the inlet tube 41 to move along the actuating plate 45. As the inlet tube 41 moves, the teeth of the actuating plate 45 push against the actuating ring 43, causing the actuating ring 43 to rotate around the axis of the inlet tube 41 at a certain angle. The rotation of the actuating ring 43 also drives the inlet tube 41 to rotate synchronously. As the inlet pipe 41 rotates, the two lugs 44 in the arc-shaped groove of the inlet pipe 41 will squeeze the two return springs 23 of the clamping frame 21 and the locking frame 22. As the actuating ring 43 completely passes the actuating plate 45, the spring force of the two return springs 23 in the locking frame 22 and the clamping frame 21 will push the two lugs 44 of the inlet pipe 41 to rotate and reset in the opposite direction, thereby allowing the inlet pipe 41 to flip and reset in the opposite direction. Then, during the movement of the inlet pipe 41, the slide of the slip ring body 5 is rinsed by reciprocating swing. In addition, when rinsing the slide of the slip ring body 5, different positions of the slide can be completely rinsed by rotating the slip ring body 5. After the cleaning fluid in the cleaning fluid tank 31 is completely expelled, clean compressed air enters the supply pipe 33 from the cleaning fluid tank 31. The supply pipe 33 then sends the clean compressed air into the inlet pipe 41 and the arc-shaped cover 42 through the branch pipe 34. Then, the spray holes of the arc-shaped cover 42 start to spray out clean compressed air to blow the slide of the flushed slip ring body 5. After the slide of the entire slip ring body 5 is blown clean, lubricating oil can be dripped onto the slide of the slip ring body 5 for lubrication, and the maintenance process of the entire fan slip ring is completed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
