Description

Technical Field

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

[0002] As one of the key components of a generator, the cleaning effect of the generator slip ring directly affects the generator's operating performance.

[0003] However, in actual operation, dust, dirt, and other impurities easily accumulate on the slip ring surface, increasing friction between the slip ring and carbon brushes. During generator operation, the carbon brushes contact the rotating slip rings, and carbon dust is easily produced through wear. When dirt and carbon dust reach a certain level, they increase friction between the carbon brushes and slip rings, leading to poor contact, increased resistance, excessively high carbon brush temperatures, rapid wear, and frequent sparking. If these phenomena are not eliminated in time, it can cause generator arcing, and in severe cases, burn out the slip rings and carbon brush holders, resulting in unplanned shutdowns and equipment damage, causing significant economic losses. Furthermore, during daily operation, some carbon dust falls into the slip ring grooves, and some forms carbon dust scale that adheres to the slip ring surface, making cleaning difficult. Therefore, it is necessary to provide a device capable of cleaning generator slip rings to improve generator operational safety. Utility Model Content

[0021] like Figure 1-2 As shown, this utility model discloses a generator slip ring cleaning device, installed on a carbon brush holder. It includes a housing 1, a vertical rotating brush 2, a drive motor 4, and a dust collection assembly. The first side of the vertical rotating brush 2 is located inside the housing 1, and the second side is located outside the housing 1. The vertical rotating brush 2 is rotatably connected to the housing 1. The drive motor 4 is located inside the housing 1 and is used to drive the vertical rotating brush 2 to rotate. The dust collection assembly is used to clean and collect the carbon powder swept off. In this embodiment, the brush body of the vertical rotating brush 2 is made of a high-temperature resistant and wear-resistant soft material. A rotating shaft 3 is located in the middle. The upper part of the rotating shaft 3 is connected to the lower side of the drive shaft 5 of the drive motor 4, and the lower side is connected to the inside of the housing 1.

[0022] When in use, install this device on the carbon brush holder, start the drive motor 4, the drive shaft 5 of the drive motor 4 drives the rotating shaft 3 to rotate, thereby causing the vertical rotating brush 2 to rotate on the surface of the collector ring. At the same time, start the dust collection component to clean up and collect the carbon powder that has been swept down.

[0023] This invention allows for the periodic cleaning of carbon powder from the slip ring surface, maintaining good contact performance between slip rings, reducing carbon brush contact resistance and slip ring wear rate, thereby improving the overall performance and stability of the generator. Furthermore, once fixed in place, this device can be used long-term, saving time and effort, significantly reducing labor costs, and facilitating routine generator maintenance.

[0024] In one embodiment, the drive motor 4 is positioned above the vertical rotating brush 2, and the dust collection assembly is positioned below the vertical rotating brush 2 and installed inside the housing 1. The bottom of the housing 1 has a dust collection port 6 corresponding to the vertical rotating brush 2. The dust collection assembly includes a dust collection pipe 7 and a vacuum cleaner 8. The air inlet of the dust collection pipe 7 is adapted to the dust collection port 6, and the air inlet of the vacuum cleaner 8 is connected to the air outlet of the dust collection pipe 7.

[0025] In this embodiment, the vacuum cleaner 8 consists of fan blades and a vacuum motor, and is located at the air outlet of the vacuum pipe 7. The vertical rotating brush 2 sweeps the toner off the surface of the collector ring, and gravity causes the toner and other impurities to fall naturally to the vicinity of the suction port 6. The air inlet of the vacuum pipe 7 is close to the suction port 6 to ensure maximum suction of the falling impurities. The vacuum motor is started, driving the fan blades to rotate and draw air inward, causing the toner to enter the vacuum pipe 7 from the suction port 6 for collection.

[0026] In one embodiment, the vacuuming assembly further includes a dust collection box 9, which is detachably connected to the vacuum cleaner 8 and is used to collect the toner powder cleaned by the vacuum cleaner 8, making it convenient for daily disassembly and cleaning.

[0027] In one embodiment, the dust collection box 9 has a cleaning port, and a door-type movable cover 10 is provided in the cleaning port. The door-type movable cover 10 is engaged with the dust collection box 9 to facilitate the removal and cleaning of the toner inside the dust collection box 9.

[0028] In one embodiment, the dust collection box 9 is made of a transparent material for easy observation.

[0029] In one embodiment, a charging assembly is also included, comprising a battery 17 and a charging port 14. The battery 17 is mounted on the inner wall of the housing 1 and electrically connected to the drive motor 4 and the vacuum cleaner 8. The charging port 14 is fixedly mounted on the outside of the housing 1 for connecting to an external power source to charge the battery 17. This allows users to replenish the cleaning device's power anytime, anywhere, without worrying about the device becoming unusable due to a depleted battery. This greatly improves the convenience and practicality of the device. In this embodiment, a power plug 16 is also provided on the housing 1, allowing the cleaning device to be directly connected to an external power source for power supply, without relying on the built-in battery 17. Through direct power supply or backup power supply, the power plug 16 ensures that the cleaning device can work continuously for extended periods, meeting different user needs.

[0030] In one embodiment, a switch button 15 is also included, which is fixedly installed on the outside of the housing 1.

[0031] In one embodiment, the device also includes a base 12 with a slot 11, which is connected to the carbon brush holder. The slot 11 has a housing 1, and the interior of the slot 11 is slidably connected to the housing 1. The entire device can move back and forth and be fixed on the slot 11, which facilitates the adjustment of the distance between the vertical rotating brush 2 and the collector ring.

[0032] In one embodiment, a fastening knob 13 is further provided on the side of the base 12. The threaded end of the fastening knob 13 is threadedly connected to the base 12, and the end face of the threaded end contacts the housing 1. In this embodiment, there are two fastening knobs 13, symmetrically arranged on both sides of the base 12. The overall fixation of the device can be adjusted by adjusting the tightness of the fastening knobs 13 to adjust the distance between the vertical rotating brush 2 and the collector ring.

[0033] The workflow of the embodiments of this utility model is as follows:

[0034] When in use, fix the base 12 of this device onto the carbon brush holder. Since the lower part of the base 12 has a slot 11, the entire device can move back and forth on the slot 11. After adjusting the vertical rotating brush 2 and the collector ring to a suitable distance, adjust the fastening knob 13 to fix the housing 1. That is, fix the cleaning device before working, adjust it to a suitable distance so that it has good contact with the surface of the collector ring, and then turn the fastening bolt to fix it after adjusting the distance.

[0035] The generator is left to idle, causing the slip ring to rotate. This activates the device, which in turn drives the vertical rotating brush 2 to rotate on the surface of the slip ring. The vacuum cleaner 8 starts and draws the cleaned toner powder into the dust collection box 9 through the suction pipe 7. The dust collection box 9 is easy to observe and can be removed for convenient daily cleaning and maintenance. The upper part is equipped with a door-type movable cover 10 for easy cleaning of the internal toner powder.

[0036] This invention allows for the periodic cleaning of carbon powder from the slip ring surface, maintaining good contact performance between slip rings, reducing carbon brush contact resistance and slip ring wear rate, thereby improving the overall performance and stability of the generator. Furthermore, once fixed in place, this device can be used long-term, saving time and effort, significantly reducing labor costs, and facilitating routine generator maintenance.
