Description

Technical Field

[0001] This utility model belongs to the field of power equipment cleaning technology, specifically relating to a transformer high-voltage bushing cleaning device. Background Technology

[0002] In power systems, transformers, as key equipment for energy conversion and transmission, are crucial for ensuring the safety and reliability of the power grid. High-voltage bushings, serving as electrical insulation and connection components between the transformer and the external environment, are exposed to the complex outdoor environment for extended periods. They are susceptible to environmental factors such as dust, dirt, salt, and moisture, leading to a decline in insulation performance. In severe cases, this can cause flashover, short circuits, and other faults, affecting the normal operation of the transformer and even the stability of the entire power system. Therefore, regularly cleaning and maintaining high-voltage bushings to ensure their surface cleanliness is a necessary measure to prevent such faults and ensure the safe operation of transformers.

[0003] Traditional high-pressure bushing cleaning methods mainly rely on manual operation, requiring operators to wear safety protective equipment and climb to the vicinity of the bushings to manually wipe them one by one. However, manual cleaning is not only time-consuming, but also results in inconsistent cleaning quality due to differences in the physical strength and cleaning skills of the workers, leading to a large number of bushings that are not thoroughly cleaned and low cleaning efficiency.

[0004] A high-voltage bushing cleaning tool is currently disclosed, featuring slits in the cleaning sponge to facilitate cleaning of the bushing skirts, effectively reducing the number of skirts missed and improving cleaning efficiency. However, this patent still requires operators to climb to the vicinity of the bushing for operation, which poses risks of falls and electric shock during the cleaning process, making it difficult to guarantee personal safety. Furthermore, this patent still requires manual scrubbing, which is still limited by the operator's cleaning skills and physical strength, limiting the improvement in cleaning speed and effectiveness, and failing to meet the needs of large-scale substations for efficient cleaning of high-voltage bushings. Therefore, there is an urgent need for a transformer high-voltage bushing cleaning device that can solve the above problems. Utility Model Content

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments.

[0023] Example 1:

[0024] See attached Figures 1-2A transformer high-voltage bushing cleaning device includes a mobile water supply unit, a cleaning unit, and a controller. The mobile water supply unit includes a transport vehicle 1 and a housing 2. The housing 2 is positioned above the transport vehicle 1. A mounting frame 3 is provided on the housing 2. A high-pressure water pump for receiving and pressurizing clean water from the outside is installed inside the housing 2. The cleaning unit includes an electric telescopic rod 4, an adjusting component 5, and a high-pressure cleaning component 6. The electric telescopic rod 4 is detachably connected to the housing 2 via the mounting frame 3. The adjusting component 5 is located on the electric telescopic rod 4 and cooperates with the high-pressure cleaning component 6. The high-pressure cleaning assembly 6 is used to adjust the angle at which it cleans the high-pressure sleeve. The high-pressure cleaning assembly 6 includes an arc-shaped bracket 61 and several nozzles 62. A fluid channel is provided inside the arc-shaped bracket 61. A water supply pipe 7 is connected to the outlet end of the high-pressure water pump. The water supply pipe 7 extends out of the housing 2, and its end communicates with the fluid channel inside the arc-shaped bracket 61. Several nozzles 62 are evenly distributed circumferentially on the arc-shaped inner wall of the arc-shaped bracket 61. The lower ends of each nozzle 62 communicate with the fluid channel. The controller is electrically connected to the electric telescopic rod 4, the adjusting assembly 5, and the high-pressure water pump. As can be seen from the above structure, the transport vehicle 1 has rollers at the bottom to support the housing 2 and transport it. A fixing frame 3 is provided on the housing 2. When the high-pressure cleaning assembly 6 needs to be moved, the electric telescopic rod 4 can be installed on the housing 2 via the fixing frame 3 for transport by the transport vehicle 1, saving the operator's effort and time. The housing 2 is also equipped with a high-pressure water pump, which receives and pressurizes external clean water before supplying it to the high-pressure cleaning assembly 6 via the water supply pipe 7. The electric telescopic rod 4 can adjust its length to change the height of the high-pressure cleaning assembly 6 relative to the ground, thus meeting the height requirements for cleaning the high-pressure sleeve. During use, the operator simply holds the electric telescopic rod 4 from the ground and places the high-pressure cleaning assembly 6 over the outside of the high-pressure sleeve for cleaning. This invention eliminates the need for operators to climb to higher ground for cleaning, ensuring their safety during the process. Furthermore, since the operator can complete the cleaning work from the ground, it saves time spent climbing and returning to the ground, significantly reducing cleaning time and conserving the operator's energy. The high-pressure cleaning assembly 6 includes an arc-shaped bracket 61 and several nozzles 62. The arc-shaped bracket 61 is formed by an upper side wall 611, a lower side wall 612, an arc-shaped inner wall, a front wall, a rear wall, and an arc-shaped outer wall. The arc-shaped outer wall is the arc-shaped wall surface on the side closer to the electric telescopic rod 4 and the arc-shaped outer wall surface on the side away from the electric telescopic rod 4.Several nozzles 62 are evenly distributed circumferentially on the inner arc of the arc-shaped support 61. The lower ends of the nozzles 62 are connected to the fluid channel. The arc-shaped support 61 has a fluid channel. The water supply pipe 7 extends out of the housing 2 and its end is connected to the fluid channel of the arc-shaped support 61. Pressurized water is delivered to the nozzles 62 through the fluid channel and sprayed outward. During cleaning, simply insert the nozzles through the notch in the arc-shaped support 61 into the outer side of the high-pressure sleeve and start the high-pressure water pump to allow the nozzles 62 to perform high-pressure water spraying on the high-pressure sleeve. The adjustment component 5 is mounted on the electric telescopic rod 4 and cooperates with the high-pressure cleaning component 6 to change the angle at which the high-pressure cleaning component 6 cleans the high-pressure sleeve, achieving 360° circumferential cleaning without dead angles and greatly improving the cleaning effect of the high-pressure sleeve. The controller is wirelessly or wiredly connected to the electric telescopic rod 4, the adjusting component 5, and the high-pressure water pump, respectively, to control the length of the electric telescopic rod 4, the angle of the arc-shaped support 61, and the start / stop and pump speed of the high-pressure water pump, adapting to the cleaning needs of high-pressure bushings in different environments. This invention enables operators to clean high-pressure bushings from the ground, significantly shortening cleaning time and improving cleaning efficiency while ensuring the personal safety of operators, thus meeting the needs of large-scale substations for efficient cleaning of high-pressure bushings.

[0025] Example 2:

[0026] See attached Figures 1-3 Based on Embodiment 1, the angle between the plane containing the upper sidewall 611 of the arc-shaped bracket 61 and the plane containing the lower sidewall 612 of the arc-shaped bracket 61 is 90°-180°. As can be seen from the above structure, a notch is formed between the upper sidewall 611 and the lower sidewall 612 of the bracket, allowing the high-pressure bushing to extend into it. The angle between the plane containing the upper sidewall 611 and the plane containing the lower sidewall 612 is 90°-180° to minimize the need for operators to adjust the position of the electric telescopic rod 4 during cleaning of the high-pressure bushing, thus saving the operator's physical effort.

[0027] The included angle between any two adjacent nozzles 62 is the same, and the included angle ranges from 30° to 72°. As can be seen from the above structure, the same included angle between adjacent nozzles 62 ensures more uniform high-pressure water pressure from each nozzle 62, facilitating consistent flushing of the high-pressure sleeve circumferentially. Setting the included angle between adjacent nozzles 62 to a range of 30° to 72° ensures that all parts of the high-pressure sleeve are flushed, guaranteeing a cleaning effect. Specifically, the included angle between adjacent nozzles 62 can be selected as 45° or 60°.

[0028] The electric telescopic rod 4 includes a fixed rod 41, a movable rod 42, and a drive motor. The fixed rod 41 is sleeved on the outer side of the lower part of the movable rod 42. The drive motor is controlled by a controller to drive the movable rod 42 to extend outward or retract inward relative to the fixed rod 41. As can be seen from the above structure, the electric telescopic rod 4 is existing technology. Through the controller's control of the drive motor, the movable rod 42 is driven to extend outward or retract inward relative to the fixed rod 41, adjusting the length of the movable rod 42 extending outward relative to the fixed rod 41 to meet the required cleaning height.

[0029] It also includes several pipe fixing clips 9; these clips 9 are respectively disposed on the outer peripheral walls of the movable rod 42 and the fixed rod 41; the pipe fixing clips 9 are used to partially fix the water supply pipe 7 to the electric telescopic rod 4. As can be seen from the above structure, the several pipe fixing clips 9, respectively disposed on the outer peripheral walls of the movable rod 42 and the fixed rod 41, fix the portion of the water supply pipe 7 extending from the housing 2 to the arc-shaped bracket 61, preventing the water supply pipe 7 from interfering with the operator's cleaning during cleaning. Specifically, the distance between each pipe fixing clip 9 in the extension direction of the electric telescopic rod 4 can be set to be the same.

[0030] The adjustment assembly 5 includes a connector 51, an arc-shaped guide rail 52, a rotary motor, and a gear 53; the end of the connector 51 is fixedly connected to the front end of the movable rod 42; the front end of the connector 51 is fixedly connected to the arc-shaped guide rail 52; the arc-shaped bracket 61 is movably mounted on the inner side of the arc-shaped guide rail 52; the arc-shaped guide rail 52 provides guidance for the arc-shaped bracket 61 to rotate along the axis of the arc-shaped bracket 61; a bracket rack 613 is provided on the arc-shaped outer wall of the arc-shaped bracket 61; the arc-shaped guide rail 52 has a first opening connecting the inner and outer sides of the arc-shaped guide rail 52; the rotary motor is mounted on the outer side of the arc-shaped guide rail 52 and is driven by the gear 53; the gear 53 is rotatably mounted on the outer side of the arc-shaped guide rail 52, and the teeth on the gear 53 pass through the first opening and mesh with the bracket rack 613; the controller is electrically connected to the rotary motor. As can be seen from the above structure, the front end of the connector 51 is fixedly connected to the arc-shaped guide rail 52 to provide support for the arc-shaped guide rail 52, and the end is fixedly connected to the front end of the movable rod 42. As the movable rod 42 extends and retracts, the height of the arc-shaped guide rail 52 relative to the ground is indirectly adjusted. The arc-shaped bracket 61 is movably installed on the inner side of the arc-shaped guide rail 52, so that the arc-shaped bracket 61 can only rotate along the axis of the arc-shaped bracket 61 when it is moving. Specifically, the front and rear walls of the arc-shaped guide rail 52 may be provided with arc-shaped guide grooves, and the front and rear walls of the arc-shaped bracket 61 are provided with arc-shaped guide protrusions that cooperate with the arc-shaped guide grooves. The rotary motor is installed on the outer side of the arc-shaped guide rail 52 and is driven by the gear 53. The gear 53 is rotatably installed on the outer side of the arc-shaped guide rail 52, and the axis of the gear 53 is parallel to the axis of the arc-shaped guide rail 52. The arc-shaped bracket 61 has a bracket rack 613 on its arc-shaped outer wall. The arc-shaped guide rail 52 has a first opening connecting the inner and outer sides of the arc-shaped guide rail 52. The teeth on the gear 53 pass through the first opening and mesh with the bracket rack 613. The rotary motor is controlled by the controller to drive the gear 53 to rotate clockwise or counterclockwise, thereby driving the arc-shaped bracket 61 to rotate clockwise or counterclockwise along its own axis, realizing the cleaning angle adjustment function. This utility model uses the meshing of gears and racks to make the arc-shaped guide rail 52 rotate along its own axis, thereby changing the angle between the nozzle 62 and the high-pressure sleeve, realizing a thorough cleaning of the high-pressure sleeve circumferentially without dead angles, and achieving a good cleaning effect.

[0031] Example 3:

[0032] See attached Figures 1-3Based on Embodiment 2, the fixing frame 3 is located on the top of the housing 2; the top of the fixing frame 3 has a horizontally arranged inclined groove 31 that is higher at the front and lower at the back; a baffle 311 is provided at the rear end of the inclined groove 31; the top of the fixing frame 3 is also detachably provided with several fixing members 32; the fixing members 32 are arranged perpendicular to the extension direction of the inclined groove 31, and the several fixing members 32 are arranged in parallel along the extension direction of the inclined groove 31; the several fixing members 32 are used to fix the position between the electric telescopic rod 4 and the housing 2 after the electric telescopic rod 4 is placed in the inclined groove 31. As can be seen from the above structure, the fixing frame 3 is located on the top of the housing 2, and the top of the fixing frame 3 has a horizontally arranged inclined groove 31. The inclined groove 31 is used to place the electric telescopic rod 4 when the device moves, and the inclined groove 31 is set to be higher at the front and lower at the back to keep the high-pressure cleaning component 6 located at the front end of the electric telescopic rod 4 away from the ground. A baffle 311 is provided at the rear end of the inclined groove 31 to prevent the rear end of the electric telescopic rod 4 from falling to the ground. The top of the mounting bracket 3 is also detachably provided with several fixing members 32. The fixing members 32 are arranged perpendicular to the extension direction of the inclined groove 31, and the fixing members 32 are arranged in parallel along the extension direction of the inclined groove 31. The fixing members 32 can be movable clamps from the prior art. By opening and closing the movable clamps, the operation of fixing the electric telescopic rod 4 in the inclined groove 31 or removing it from the inclined groove 31 can be completed.

[0033] The inclined groove 31 is a stepped groove. As can be seen from the above structure, the inclined groove 31 is set as a stepped groove to adapt to the shape of the electric telescopic rod 4 and facilitate placement.

[0034] It also includes a pipe placement basket 8; the pipe placement basket 8 is located on the rear side wall of the box 2, with its opening facing upwards; the rear side wall of the box 2 is also provided with a through hole communicating with the interior of the pipe placement basket 8; the water supply pipe 7 passes through the through hole and exits the box 2. As can be seen from the above structure, in order to meet the cleaning needs of different heights, the water supply pipe 7 is relatively long. The pipe placement basket 8 can be used to partially store the water supply pipe 7 during the transportation of the device using the transport vehicle 1, so that this part will not fall to the ground and prevent the water supply pipe 7 from being damaged by collision or cutting during transportation, thus affecting the efficiency of the cleaning work.

[0035] The arc-shaped bracket 61 has an inlet on its front wall that communicates with the interior of the fluid channel; the arc-shaped guide rail 52 has a notch on its front wall that corresponds to the position of the inlet.
