Description

Technical Field

[0001] This invention relates to the field of power transmission line cleaning equipment technology, and in particular to a power transmission line cleaning device for extreme weather conditions with micro-topography. Background Technology

[0002] When cleaning insulators on high-voltage power lines located in the field, workers need to climb the towers to wash the insulators in a very small operating space. Workers typically use water guns to wash the insulators, requiring them to constantly adjust their body position to control the water spray direction. Due to the limited operating space, the cleaning work is inconvenient. After cleaning, a large number of water droplets remain on the insulators. In winter, when outdoor temperatures are low, these water droplets easily freeze. Additionally, snow or dust can easily accumulate on the insulators, which can easily lead to insulator flashover and cause transmission line faults. Summary of the Invention

This invention uses a limiting mechanism to fix the position of the cleaning device for transmission lines under extreme weather conditions with micro-topography, and aligns the cleaning mechanism with the insulator. The moving mechanism drives the cleaning mechanism to move, and at the same time the cleaning mechanism moves, the cleaning end of the cleaning mechanism rotates to clean the dust or snow on the insulator. This makes it convenient for workers to install and operate, and does not require workers to perform dangerous actions at high altitudes.

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Combined with appendix Figures 1-4The aforementioned power transmission line micro-topography extreme weather cleaning device includes two limiting mechanisms 1. A moving mechanism 2 and a cleaning mechanism 3 are installed between the two limiting mechanisms 1. The cleaning mechanism 3 is located on the moving mechanism 2 and slidably connected. The driving end of the moving mechanism 2 is located inside the cleaning mechanism 3, and the rotating end of the cleaning mechanism 3 is connected to the driving end of the moving mechanism 2. The liquid storage end of the cleaning mechanism 3 is connected to the liquid supply pipe 4. The spraying end of the cleaning mechanism 3 cleans the insulators on the power transmission line. All electrical equipment inside the moving mechanism 2 is connected to an external control device, which controls the operation of all electrical equipment inside the moving mechanism 2. The liquid supply pipe 4 is connected to an external gas or liquid supply device.

[0018] The limiting mechanism 1 includes an arc-shaped limiting plate 101, a fixing rod 102, a connecting screw 103, and a snap-fit ​​bracket 104. There are two arc-shaped limiting plates 101, which are connected by a connecting shaft. A moving mechanism 2 is installed on the arc-shaped limiting plate 101, and the upper surfaces of the two arc-shaped limiting plates 101 are respectively fixedly connected to the fixing rod 102. The top end of the fixing rod 102 is fixedly connected to the snap-fit ​​bracket 104, and the two snap-fit ​​brackets 104 are connected by a connecting screw 103.

[0019] The snap-fit ​​bracket 104 is provided with snap-fit ​​grooves, and the slots of the snap-fit ​​grooves on the two snap-fit ​​brackets 104 correspond to each other. The snap-fit ​​grooves are located on the upper side of the connecting screw 103, and snap-fit ​​brackets 104 are snapped onto the tower installed on the insulator.

[0020] The moving mechanism 2 includes a transmission rod 201, a sliding rod 202, a gear 203, a dual-axis servo motor 204, and a bevel gear 205. There are two transmission rods 201 and two sliding rods 202, arranged alternately. The upper and lower ends of the transmission rods 201 and 202 are respectively connected to the arc-shaped limiting plate 101. A cleaning mechanism 3 is slidably connected to the transmission rods 201 and 202. The dual-axis servo motor 204 is located within the moving end of the cleaning mechanism 3, and gears 203 and bevel gears 205 are fixedly connected to the motor shafts at both ends of the dual-axis servo motor 204. The gears 203 correspond to and mesh with the transmission rods 201. The bevel gears 205 are connected to the drive end of the cleaning mechanism 3. The sliding rod 202 is a telescopic rod; by contracting the transmission rods 201 and 202, the overall volume of the cleaning device for power transmission line micro-topography and extreme weather conditions is reduced, making it easier for workers to handle.

[0021] The transmission rod 201 includes a first rod body 201.1, a second rod body 201.2, a first rack 201.3, and a second rack 201.4. The first rod body 201.1 has a sliding groove and a connecting groove, and the sliding groove and the connecting groove are interconnected. The first rack 201.3 is fixedly connected to the groove walls on both sides of the connecting groove. The second rod body 201.2 is slidably connected in the sliding groove, and the second rack 201.4 is fixedly connected to the second rod body 201.4. The second rack 201.4 is located between the two first racks 201.3 and is slidably connected. Both the first rack 201.3 and the second rack 201.4 are meshed with the gear 203. The top end of the first rod body 201.1 and the bottom end of the second rod body 201.2 are respectively connected to the arc-shaped limiting plate 101.

[0022] The tooth spacing on the first rack 201.3 and the second rack 201.4 is the same. When adjusting the length of the first rod 201.1 and the second rod 201.2, the tooth grooves of the first rack 201.3 and the second rack 201.4 on the first rod 201.1 and the second rod 201.2 are aligned to avoid misalignment of the tooth grooves, which would prevent the gear 203 from moving.

[0023] The cleaning mechanism 3 includes a movable frame 301, a nozzle 304, a connecting pipe 305, a bevel gear ring 306, an arc-shaped rotating ring 307, and an arc-shaped rotating plate 308. There are two movable frames 301, which are slidably connected to the transmission rod 201 and the sliding rod 202. One movable frame 301 has a mounting groove, in which a dual-axis servo motor 204 is installed. Both movable frames 301 have rotating grooves on their inner walls, which are connected to the mounting grooves. An arc-shaped rotating ring 307 is rotatably connected within each rotating groove, and the inner and outer walls of the arc-shaped rotating ring 307 are respectively... A bevel gear ring 306 and an arc-shaped rotating plate 308 are fixedly connected. The bevel gear ring 306 and the bevel gear 205 are positioned and meshed. The arc-shaped rotating plate 308 is equipped with nozzles 304 arranged at equal intervals. Two movable frames 301 are provided with storage tanks, and the exhaust ports of the storage tanks are connected to the arc-shaped rotating plate 308 through a connecting pipe 305. The air inlet of the storage tank is connected to the exhaust port of the liquid supply pipe 4. The arc-shaped rotating plate 308 only covers one side of the insulator. During rinsing, snow or dust will flow to the side that is not rinsed, preventing dust or snow from accumulating in the middle of the insulator.

[0024] Semi-circular split bearings 302 are fixedly connected to the two side walls of the storage tank, and an arc-shaped rotating plate 303 is fixedly connected between the rotating ends of the two semi-circular split bearings 302. A connecting pipe 305 is fixedly connected to one of the arc-shaped rotating plates 303.

[0025] The arc-shaped rotating plate 308 is a hollow plate, and the air inlet of the arc-shaped rotating plate 308 is connected to the connecting pipe 305. The arc-shaped rotating plate 308 is provided with equally spaced exhaust ports, and a nozzle 304 is installed in the exhaust port.

[0026] The two ends of the movable frame 301 are respectively fixedly connected with sealing gaskets 309, and the sealing gaskets 309 are U-shaped. The position of the sealing gaskets 309 corresponds to the position of the storage tank. The sealing gaskets 309 on the two movable frames 301 are corresponding and in contact with each other. The sealing gaskets 309 connect the two storage tanks and seal the gap between the two storage tanks.

[0027] The aforementioned power transmission line micro-topography extreme weather clearing device, in use, involves the operator attaching the clamping brackets 104 on the upper and lower arc-shaped limiting plates 101 to the tower where insulators are installed, and ensuring that two movable frames 301 surround the insulators. The two clamping brackets 104 are fixed together by connecting screws 103, thus fixing the position of the movable frames 301. A dual-axis servo motor 204 drives gears 203 and bevel gears 205 to rotate. During rotation, gear 203 moves along the first rack 201.3 and the second rack 201.4, simultaneously causing the movable frames 301 to move up and down. During this up-and-down movement, the movable frames 301... The bevel gear 205 drives the arc-shaped rotating ring 307, which is equipped with a bevel gear ring 306, to rotate. The rotation of the arc-shaped rotating ring 307 drives the arc-shaped rotating plate 308, which is equipped with a nozzle 304, to rotate. This causes the nozzle 304 to rotate around the insulator, cleaning the insulator thoroughly. The liquid supply pipe 4 provides flushing water or gas to the nozzle 304, which blows the flushing water or gas onto the insulator. During the downward movement of the moving frame 301, the flushing water cleans the dust or snow on the insulator. During the upward movement of the moving frame 301, the gas blows away any remaining water droplets on the insulator, preventing water droplets from remaining on the insulator and preventing the insulator from freezing.
