Description

Technical Field

[0001] This invention relates to transformer bushing porcelain skirts, specifically a transformer bushing porcelain skirt cleaning device and its usage method. Background Technology

[0002] Transformer bushing porcelain skirts, when operating outdoors for extended periods, are prone to accumulating dust, salt spray, bird droppings, and other contaminants. In humid environments, they can easily form conductive water films, triggering flashover discharges and threatening power grid safety. Regular cleaning is essential. Existing cleaning methods have significant shortcomings: Manual high-altitude live-line cleaning is high-risk and inefficient. Brushes and water guns are ineffective at cleaning stubborn stains at the base of the folds in the ceramic skirt, and wastewater dripping at will can easily pollute the power equipment. Traditional offline cleaning equipment is mostly single-station with only fixed nozzles, resulting in cleaning dead zones. It also relies on manual loading and unloading and manual clamping of sleeves, leading to a high rate of damage to ceramic workpieces due to impacts.

[0003] To overcome the above-mentioned defects, a transformer bushing porcelain skirt cleaning device and its usage method are proposed to solve the existing problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a transformer bushing porcelain skirt cleaning device and its usage method, which solves the problem of inconvenient cleaning of bushing porcelain skirts.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a transformer bushing porcelain skirt cleaning device, comprising a frame and a suspension groove, wherein a plurality of suspension grooves are provided, and the plurality of suspension grooves are all located at the top of the frame, a bushing porcelain skirt is invertedly assembled inside the suspension groove, a cleaning mechanism is provided inside the frame, a positioning mechanism is provided on the surface of the frame, and a lifting mechanism is provided at the top of the frame.

[0006] Preferably, the cleaning mechanism includes a tube sleeve, and a plurality of tube sleeves are provided, and the plurality of tube sleeves are rotatably disposed inside the frame. A protective shell is fixedly connected to the surface of the tube sleeve, and a brush roller is rotatably disposed inside the protective shell and on both sides of the tube sleeve. An inner toothed cover is fixedly connected to the bottom of the inner cavity of the frame, and a first gear that meshes with the inner toothed cover is fixedly connected to the surface of the output shaft of the brush roller. A pulley is fixedly connected to the surface of the sleeve, and a belt is connected between two adjacent pulleys. The front and rear sides of the sleeve are connected to a spray pipe, and the surface of the spray pipe is surrounded by several spray holes. A motor is fixedly connected to the bottom of the frame through a bracket. The surface of the motor output shaft and the surface of the sleeve in the middle are fixedly connected to a second gear that meshes with each other.

[0007] Preferably, the positioning mechanism includes two electric telescopic rods, which are fixedly mounted on both sides of the frame. Several limiting grooves are provided on the front and rear sides of the top of the frame, and adjacent limiting grooves are connected to the suspension groove. A toothed clamping plate is slidably mounted inside the limiting groove. Gear shafts are rotatably mounted on the front and rear sides of the top of the frame. A toothed frame that meshes with the gear shaft is fixedly connected to the top of the extension end of the electric telescopic rod.

[0008] Preferably, the lifting mechanism includes sleeves, and two sleeves are provided, with the two sleeves fixedly disposed on both sides of the frame respectively. A movable rod is slidably disposed inside the sleeve, and a return spring is fixedly connected between the movable rod and the sleeve. The tops of the two movable rods are fixedly connected to the lifting frame, and a top rod for use with the lifting frame is fixedly connected to the bottom of the toothed frame cavity.

[0009] Preferably, the top of the frame is provided with a storage slot adapted to the support frame, and control buttons are installed on both sides of the bottom of the storage slot through mounting slots. The top of the frame is provided with sound and light prompts adapted to the control buttons.

[0010] Preferably, a plurality of protective covers are fixedly connected to the top of the inner cavity of the frame, and wiping plates adapted to the protective covers are fixedly connected to both sides of the protective shell.

[0011] Preferably, the bottom of the frame is provided with a main water inlet pipe, and the top of the main water inlet pipe is connected to a water supply branch pipe adapted to the pipe sleeve. The water supply branch pipe on the same side is connected to the bottom of the pipe sleeve through a rotary joint.

[0012] Preferably, one side of the frame is connected to an external drainage pipe.

[0013] The present invention also provides a method for using a transformer bushing porcelain skirt cleaning device, specifically including the following steps: S1. Connect the on-site water pump to the main water inlet pipe in advance, and supply water to the pipe sleeve and spray pipe through the main water inlet pipe; Then the motor is started, which drives two adjacent second gears to mesh through the output shaft. The rotation of the second gears drives the tube sleeve, protective shell, brush roller and spray pipe to rotate. The rotation of the spray pipe sprays the tube sleeve ceramic skirt and protective cover in a circumferential manner. The rotation of the brush roller cleans the tube sleeve ceramic skirt in a circumferential manner. The circumferential movement of the brush roller is synchronized with the meshing of the first gear and the inner tooth cover, which causes the brush roller to rotate and deeply clean the tube sleeve ceramic skirt. The wastewater from the cleaning and swiping process is blocked by the protective cover. When the protective cover rotates, it drives the wiping plate to clean the inner wall of the protective cover, and the spray pipe sprays around the perimeter to guide the dirt scraped from the inner wall of the protective cover. S2. After the ceramic skirt of the sleeve is cleaned, start the electric telescopic rod. The extended end of the electric telescopic rod drives the toothed frame, which in turn meshes with the gear shaft. The gear shaft then meshes with the toothed clamping plate, causing the toothed clamping plate to retract and disengage from the ceramic skirt of the sleeve. S3. When the electric telescopic rod drives the tooth frame to rise, the tooth frame drives the top rod to rise, causing the top rod to gradually contact the lifting frame and lift the lifting frame. The lifting frame centrally lifts several sleeve porcelain skirts to rise. When the corresponding sleeve ceramic skirt is reassembled and cleaned, the retraction stroke of the electric telescopic rod needs to be reset twice in advance. Specifically, the extension end of the electric telescopic rod and the lifting frame begin to reset. During the reset process, the lifting frame enters the inside of the storage slot. When it enters the storage slot, the lifting frame presses the control button, which triggers the light of the audible and visual indicator. At this time, the electric telescopic rod stops and the sleeve ceramic skirt is placed into the inside of the suspension slot. After placement, the electric telescopic rod continues to reset, causing the subsequent stroke of the electric telescopic rod to drive the toothed clamping plate to clamp and limit the surface of the sleeve ceramic skirt.

[0014] Beneficial effects

Compared with existing technologies, it has the following advantages: (1) The transformer bushing porcelain skirt cleaning device and its usage method, by setting up a cleaning mechanism, a positioning mechanism and a lifting mechanism, enables the device to complete the automatic centering and clamping of the bushing porcelain skirt, multi-station synchronous rotating spraying and brushing, and automatic lifting and unloading after cleaning through the meshing transmission of the gear shaft and tooth frame, the buffer lifting linkage of the internal reset spring of the bushing, and the synchronous water conveyance of the water supply branch pipe at the bottom of the bushing. The entire process is automated and continuous, eliminating the manual operation links of workpiece loading and unloading and positioning and locking. The equipment supports multi-station synchronous parallel cleaning. Compared with traditional single-station cleaning equipment, the batch cleaning efficiency is significantly improved, effectively reducing the time of substation maintenance and supporting cleaning operations.

[0016] (2) The transformer bushing ceramic skirt cleaning device and its usage method, by setting up a spray pipe, a brush roller, an inner toothed cover and a first gear, causes the brush roller to synchronously realize the revolution and rotation grinding action. In conjunction with the spray pipe, it can penetrate deep into the root of the ceramic skirt folds to remove stubborn dirt and completely eliminate the cleaning dead corners that exist in traditional single fixed spray head.

[0017] (3) The transformer bushing porcelain skirt cleaning device and its usage method, by setting up a protective cover, a wiping plate and a water inlet main pipe, enables the wastewater thrown out during cleaning to be concentrated and blocked by the protective cover, and the wiping plate rotates synchronously with the cleaning main shaft to clean the stains on the inner wall of the protective cover, so that the stains can be easily discharged into the interior of the frame.

Connect the on-site water pump to the main water inlet pipe 9 in advance, and supply water to the pipe sleeve 401 and the spray pipe 408 through the main water inlet pipe 9. Then, the motor 409 is started, which drives the two adjacent second gears 410 to mesh through the output shaft.

The rotation of the spray pipe 408 sprays the sleeve ceramic skirt 3 and protective cover 7 in a circular manner. The rotation of the brush roller 403 cleans the sleeve ceramic skirt 3 in a circular manner. The circular movement of the brush roller 403 is synchronized with the meshing of the first gear 405 and the inner tooth cover 404, which causes the brush roller 403 to rotate and perform deep cleaning of the sleeve ceramic skirt 3.

When the electric telescopic rod 504 drives the tooth frame 505 to rise, the tooth frame 505 drives the top rod 605 to rise, causing the top rod 605 to gradually contact the lifting frame 604 and lift the lifting frame 604 to rise. The lifting frame 604 centrally controls the lifting of several sleeve porcelain skirts 3 to rise. When the corresponding sleeve ceramic skirt 3 is reassembled and cleaned, the retraction stroke of the electric telescopic rod 504 needs to be reset twice in advance. Specifically, the extension end of the electric telescopic rod 504 and the lifting frame 604 start to reset.
