Description

Technical Field

[0001] This utility model relates to the field of generator set slip ring maintenance technology, specifically a slip ring cleaning device. Background Technology

[0002] Generator slip rings are a crucial component of the generator excitation system. Operating using carbon brushes, they are used in electromechanical systems requiring continuous rotation while transmitting power and signals from a fixed to a rotating position. During operation, slip rings accumulate significant amounts of dust, oil, and other contaminants. Dust buildup on the slip ring surface hinders heat dissipation; oil leaks, potentially originating from internal generator lubricant leaks, reduce the slip ring's insulation and may even decrease its conductivity. Therefore, current practices utilize slip ring cleaning devices for regular maintenance.

[0003] However, existing slip ring cleaning devices still have the following technical problems during use:

[0004] The existing cleaning method involves placing the slip ring in a cleaning solution and using an ultrasonic cleaner for efficient cleaning. However, after cleaning, the cleaning solution adhering to the surface of the slip ring cannot be dried quickly, resulting in a large amount of cleaning solution adhering to the outer wall of the slip ring, which easily attracts dust and affects the cleaning effect.

[0005] Therefore, a collector ring cleaning device is proposed to solve the above-mentioned problems. Utility Model Content

[0024] Example:

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A collector ring cleaning device includes a cleaning tank 1. An ultrasonic cleaner 2 is fixed on the left side of the cleaning tank 1. The ultrasonic cleaner 2 first converts electrical energy into high-frequency mechanical vibration through a transducer. The frequency is usually ≥20kHz. The vibration is transmitted to the liquid through the wall of the cleaning tank, forming alternating dense and sparse sound wave radiation. A bracket 3 is fixed on the rear side of the cleaning tank 1. A telescopic cylinder 4 is fixed on the upper side of the bracket 3. A rotating mechanism is fixed on the lower end of the telescopic cylinder 4. A fixing mechanism is fixed on the lower end of the rotating mechanism. A collector ring 5 is fixed on the outside of the fixing mechanism.

[0027] Fixed rods 6 are fixed to the left and right ends of the upper side of the cleaning tank 1. An annular plate 7 is fixed to the upper ends of the two fixed rods 6. A moving mechanism is fixed to the left end of the inner wall of the annular plate 7. The moving mechanism can drive the mounting plate 8 and the wiping cotton 9 at the right end to move to the right end. After the collector ring 5 is cleaned, the cleaning liquid attached to its surface can be wiped off. The mounting plate 8 is fixed to the right side of the moving mechanism. The wiping cotton 9 is fixed to the right side of the mounting plate 8. Symmetrical connecting rods 10 are fixed to the right end of the inner wall of the annular plate 7. An installation tube 11 is fixed to the left end of the two connecting rods 10. A fan 12 is fixed inside the installation tube 11. The fan 12 can drive the airflow to move, thereby drying the cleaning liquid on the surface of the collector ring 5.

[0028] A cleaning fluid discharge pipe 13 is fixed at the lower right end of the cleaning tank 1. When the cleaning fluid contains a large number of impurities and the cleaning effect decreases, it can be discharged through the cleaning fluid discharge pipe 13 and the cleaning fluid can be replaced.

[0029] The rotating mechanism includes a housing 14, the lower side of which is fixedly connected to the lower end of the telescopic cylinder 4. A motor 15 is fixed inside the housing 14, and a rotating rod 16 is fixed at the output end of the motor 15. The rotating mechanism can drive the collector ring 5 to rotate, so that the airflow can contact the collector ring 5 in all directions, and the wiping cotton 9 can wipe the collector ring 5 in all directions.

[0030] The fixing mechanism includes four strip plates 17, with their ends fixedly connected. The lower end of the rotating rod 16 is fixedly connected to the upper side of the strip plates 17. Each of the four strip plates 17 has a sliding locking rod 18 inside. The other end of the locking rod 18 is fixed with a rubber anti-slip block. The upper side of the strip plates 17 is threaded with a fastening bolt. One end of the fastening bolt extends into the interior of the strip plate 17 and engages with the upper side of the locking rod 18. By moving the locking rod 18 inside the strip plate 17, the locking rod 18 contacts the inner wall of the collector ring 5, thereby securing the collector ring 5.

[0031] The moving mechanism includes a fixed block 19, which is fixedly connected to the left end of the inner wall of the annular plate 7. An electric push rod 20 is fixed inside the fixed block 19. A slider 21 is fixed to the right end of the electric push rod 20. The upper and lower sides of the slider 21 are slidably connected to the inner wall of the fixed block 19. A moving rod 22 is fixed to the right side of the slider 21. The moving rod 22 is slidably connected to the right side of the fixed block 19. The right end of the moving rod 22 is fixedly connected to the left side of the mounting plate 8.

[0032] The wiping cotton 9 is compatible with the outer wall of the collector ring 5.

[0033] Working principle:

[0034] In use, the collector ring 5 is fixed by the fixing mechanism, the cleaning solution is poured into the cleaning tank 1, and the telescopic cylinder 4 is extended to move the collector ring 5 into the cleaning tank 1 so that the cleaning solution completely soaks the collector ring 5. The ultrasonic cleaner 2 is started to clean the stains on its surface. After cleaning, the telescopic cylinder 4 is retracted to move the collector ring 5 into the annular plate 7. The moving mechanism drives the wiping cotton 9 to contact the side wall of the collector ring 5, and the fan 12 is started to wipe and dry the surface at the same time, thereby removing the cleaning solution adhering to the outside of the collector ring 5.
