Description

Technical Field

[0001] This utility model relates to the technical field of generator maintenance equipment, specifically a high-efficiency generator excitation slip ring cleaning device. Background Technology

[0002] The generator excitation slip ring is a key component in generator equipment that enables electrical energy transfer between the rotor and stator. The stability of its operation directly affects the safety of the entire generator set. During long-term operation, the friction between the brushes and the slip ring inevitably generates carbon dust, which tends to accumulate on the surface of the slip ring and its insulating support parts.

[0003] When carbon powder accumulates in large quantities, it significantly reduces the insulation resistance of the generator rotor, destroys the necessary electrical isolation between the rotor and stator, and thus drastically increases the risk of insulation breakdown, posing a serious threat to the safe and stable operation of the generator set.

[0004] Currently, cleaning and maintaining the excitation slip rings of generators is a necessary but challenging task, and existing technologies mainly suffer from the following drawbacks: 1) Poor cleaning thoroughness: Due to the compact internal structure of the generator, the physical gap between the positive and negative poles of the slip ring is extremely narrow. Commonly used cleaning tools (such as brushes) are difficult to effectively reach all areas of the slip ring, especially the back of the insulator and hidden corners such as gaps, due to their fixed shape, excessive size or lack of adaptability. This results in unavoidable cleaning dead spots, and the cleaning effect cannot meet the maintenance standards. 2) Low operational efficiency: Due to poor tool adaptability and the existence of cleaning blind spots, operators often have to repeat the cleaning process multiple times to barely meet the standards. Each cleaning operation is time-consuming, typically taking 120 minutes or even longer. This not only significantly increases the downtime maintenance cost of the unit but also leads to unnecessary waste of human resources. 3) Poor operational safety: This operation presents two safety risks. Firstly, there is a risk to personal health: traditional cleaning methods cause carbon powder to be violently stirred up and dispersed into the surrounding air. If workers inhale air containing carbon powder, it will pose a potential hazard to their respiratory system. Secondly, there are equipment and operational safety risks. The stirred-up carbon powder will cause secondary pollution to the environment around the slip ring. At the same time, in order to clean dead corners, operators often have to forcibly insert their hands into narrow spaces, which can easily cause skin abrasions or crush injuries, increasing the unsafe factors of the operation.

[0005] Therefore, given the numerous shortcomings of existing cleaning technologies, such as incomplete cleaning, low efficiency, and safety concerns, there is an urgent need in this field for a specially designed device that can efficiently, thoroughly, and safely complete the cleaning of generator excitation slip rings. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides a highly efficient generator excitation slip ring cleaning device, which will effectively improve the above-mentioned problems.

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] A high-efficiency generator excitation slip ring cleaning device: like Figure 1As shown, the cleaning device includes a cleaning component 1, a vacuuming component 2, and a handheld operating component 3. The vacuuming component 2 and the handheld operating component 3 are both located on the rear side of the cleaning component 1. The vacuuming component 2 includes a vacuuming hose 201. A dust collection box 202 is located at the rear end of the vacuuming hose 201. A sealing door 209 is located at the right end of the dust collection box 202. The sealing door 209 is rotatably connected to the dust collection box 202 via a hinge 210. A convenient handle 211 is located at the right end of the sealing door 209. The sealing door 209 and the dust collection box 202 are connected by a lock cylinder 212. Specifically, the vacuum hose 201 can be a corrugated pipe, with its rear end connected to the dust collection box 202. The vacuuming component 2 generates suction through electricity, and together with the cleaning component 1, it transports the toner through the vacuum hose 201 to the dust collection box 202. A rubber sealing ring is provided at the connection between the sealing door 209 and the dust collection box 202 to improve the sealing performance of the dust collection box 202. The sealing door 209 on the dust collection box 202 is connected to the lock cylinder 212 through the hinge 210. After cleaning is completed, the sealing door 209 can be opened to quickly clean the toner inside the dust collection box 202.

[0024] like Figure 2 As shown, the cleaning assembly 1 includes a flexible rubber brush head 101 and a wide flat body 105. The flexible rubber brush head 101 is fixed to the front end of the wide flat body 105. A dust suction channel is provided inside the wide flat body 105. The rear end of the dust suction channel is connected to the front end of the dust suction hose 201. The front end of the flexible rubber brush head 101 is provided with a number of cleaning teeth 103. A dust guiding gap 104 is provided between the cleaning teeth 103. The dust guiding gap 104 is connected to the dust suction channel. The upper and lower sides of the wide flat body 105 are provided with flexible side wings 102 that can be bent. Specifically, the cleaning component 1 directly acts on the toner and is the core cleaning execution component. It has a dust suction channel inside, which can concentrate and guide the toner into the dust suction component 2. The flexible rubber brush head 101 directly contacts the cleaning surface of the slip ring. The rubber material is more flexible and has a certain friction and toughness. The cleaning teeth 103 can effectively loosen and scrape the toner attached to the surface of the slip ring. The loosened and scraped toner will be immediately captured and sucked in by the dust guide gap 104. The cleaning teeth 103 and the dust guide gap 104 work together to achieve "sweeping and sucking immediately", which greatly reduces the possibility of toner being pushed forward by the brush head or scattered in the air guide, making toner cleaning more environmentally friendly and safe, and protecting the health of operators. Specifically, the flexible side wings 102 can be made of flexible materials, which can closely fit the uneven cleaning surface during cleaning to improve the ability to capture toner. The wide and flat main body 105 is hollow inside to form a dust collection channel. The flat design is adapted to the gap between the positive and negative electrodes of the slip ring, which can flexibly adapt to complex positions and achieve cleaning without dead angles. The wide design ensures that a larger area can be covered in a single cleaning, which significantly improves cleaning efficiency.

[0025] like Figure 3 As shown, a connecting seat 4 is fixedly installed at the rear end of the wide and flat main body 105, a rotating shaft 6 is installed at the rear end of the connecting seat 4, and a connecting block 5 is rotatably connected to the rear end of the rotating shaft 6. The handheld operating component 3 includes a handle 301, which is fixedly installed at the rear end of the connecting block 5. A control switch 303 is installed at the upper end of the handle 301, and a rubber anti-slip pad 302 is sleeved on the surface of the handle 301 to increase the coefficient of friction. Specifically, the connecting seat 4, the rotating shaft 6, and the connecting block 5 work together to form a rotating joint. The rotating shaft 6, as the core component of the rotating joint, can adopt a bushing structure to enable the cleaning component 1 to swing flexibly left and right. Users do not need to rotate their wrists or bodies significantly; they only need to apply a slight force through the handle 301, and the brush head can automatically rotate the angle, greatly improving the flexibility and labor-saving of operation.

[0026] like Figure 4 As shown, mounting bases 203 are provided at the upper and lower ends of the dust collection box 202. A filter screen 204 is provided in the middle of the mounting base 203. The mounting base 203 and the dust collection box 202 are connected by fixing screws 205. A negative pressure generator 206 is fixedly installed at the right end of the dust collection box 202. An air inlet pipe 207 is fixedly installed at the left end of the negative pressure generator 206. The air inlet pipe 207 is connected to the dust collection box 202. An air outlet pipe 208 is provided at the right end of the negative pressure generator 206. Specifically, the dust collection box 202 is used to store the collected toner. Through the cooperation of the mounting base 203 and the fixing screw 205, the filter 204 can be easily replaced and cleaned. The filter 204 adopts a HEPA filter (High-Efficiency Particulate Air), which can capture extremely fine toner particles, ensuring that the air discharged from the air outlet 208 is clean, avoiding secondary dust and effectively preventing secondary pollution. Specifically, the negative pressure generator 206 is a portable electric negative pressure pump. The control switch 303 is electrically connected to the negative pressure generator 206. During the toner cleaning process, the control switch 303 controls the negative pressure generator 206 to start working. The suction force is formed in the dust collection box 202 through the air inlet pipe 207. The toner is sucked into the dust collection box 202 and intercepted by the filter screen 204. The clean air is discharged to the outside through the air outlet pipe 208 of the negative pressure generator 206.

[0027] Working principle: Before carrying out generator excitation slip ring cleaning operation, the operator first holds the handle 301 with rubber anti-slip pad 302, and adjusts it to a suitable working angle according to the gap between the positive and negative poles of the slip ring and the position of the insulator, through the plasticity of the wide flat body 105 and the elastic side wings 102. At the same time, the cleaning component 1 is flexibly rotated by the rotating shaft 6 between the connecting seat 4 and the connecting block 5 to ensure that the flexible rubber brush head 101 can be aligned with the area to be cleaned. During operation, press the control switch 303 on the handle 301 to start the negative pressure generator 206 (portable electric negative pressure pump). The negative pressure generator 206 forms a negative pressure in the dust collection box 202 through the air inlet pipe 207, and then generates suction through the suction hose 201 and the suction channel inside the wide flat body 105. At this time, move the flexible rubber brush head 101 against the surface of the slip ring. The cleaning teeth 103 at the front end of the brush head scrape off the carbon powder on the surface of the slip ring. The scraped carbon powder enters the suction channel through the dust guide gap 104 between the cleaning teeth 103, and is then sucked into the dust collection box 202 through the suction hose 201. The carbon powder is intercepted and filtered by the filter screen 204 in the dust collection box 202. The filtered clean air is discharged through the air outlet pipe 208 of the negative pressure generator 206. During the operation, the flexible side wings 102 can be used to conform to the bending characteristics of the insulator contour to clean narrow areas such as the edge of the slip ring and the back of the insulator, avoiding cleaning dead corners. After the operation is completed, turn off the control switch 303, open the sealing door 209 of the dust collection box 202 through the lock core 212, and clean the carbon powder collected inside. If the filter screen 204 is clogged, it can be replaced or cleaned by removing the fixing screws 205 on the mounting base 203, thus completing the entire cleaning and maintenance process.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
