Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power transmission line cleaning, in particular to a power transmission line cleaning device and a construction method thereof. BACKGROUND

[0002] The high-voltage transmission line is an important part of the power system, which not only undertakes the heavy task of power transmission, but also the safety and reliability of its operation is directly related to the stable development of national economy. The high-voltage transmission line is divided into cable transmission line and overhead transmission line. The cable transmission line is buried underground, which does not occupy space, but is inconvenient for construction and maintenance, and is mostly used in urban and cross-river lines. The overhead transmission line is composed of line towers, conductors, insulators, line fittings, stay wires, tower foundations, grounding wires and the like. The overhead transmission line is erected on the ground, and the line towers are used to suspend the conductors and grounding wires in the air, so as to maintain a certain safety distance between the conductors and the conductors, between the conductors and the grounding wires, between the conductors and the line towers, and between the conductors and the ground obstacles, thereby completing the power transmission task.

[0003] In many places in China, every winter, rain and snow are easy to condense on the power transmission line to form line icing. With the increase of the icing, the mechanical load increases, and the weight of the ice on the conductors, insulator strings and towers, and the wind pressure due to the increase of the wind area after icing, when the comprehensive load of the ice and wind exceeds the allowable value of the strength of the above components, the power transmission line will be damaged. After the insulator string is iced, the leakage resistance decreases, and the uneven voltage distribution is aggravated. With the increase of the icing, the local potential gradient in the insulator string is high, which may cause glow discharge, and the melting water may seep out. If the leakage current continues to increase, the glow discharge will gradually turn into white arc, and when the melting water penetrates most of the surface of the insulator string, the partial discharge will rapidly develop into full string flashover, causing the line grounding trip.

[0004] At present, part of the line section of the overhead transmission line is usually erected in a relatively remote and sparsely populated area.

[0020] By adopting the above technical solution, the mounting block is slidably set in the mounting groove of the second frame, and the mounting block is prevented from sliding in the mounting groove by the limiting component. This makes it easier to adjust the position of the two adjacent scrapers according to the distance between the two adjacent transmission lines.

[0025] Secondly, this application provides a construction method for a power transmission and transformation line cleaning device, which adopts the following technical solution:

[0026] A construction method for a power transmission and transformation line cleaning device includes the following steps:

[0027] S1. Install the mounting bracket on the power transmission line and place the scraper sleeve on the power transmission line;

[0028] S2. Secure the mounting bracket to the power transmission line using the fixing components;

[0030] S4. Clamp the power transmission line with the sliding frame by the clamping assembly, release the fixing assembly, and start the rodless cylinder to drive the mounting frame to slide closer to the sliding frame.

[0031] S5. Then, continue to fix the mounting bracket to the power transmission line using the fixing components, loosen the clamping components, and repeat the above steps S3-S4 to move the mounting bracket on the power transmission line to clean the ice on the power transmission line.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. When ice accumulates on the transmission line, the mounting bracket is fixed to the transmission line using a fixing component. Following the direction of ice breaking, a rodless cylinder drives a sliding frame closer to the ice breaking direction to slide, causing the scraper to slide along the transmission line and remove the ice. Then, a clamping component clamps the sliding frame to the transmission line. The fixing component is released, and the rodless cylinder is activated to drive the mounting bracket to slide closer to the sliding frame. The mounting bracket is then fixed to the transmission line again using the fixing component, and the clamping component is released. This process is repeated to move the mounting bracket along the transmission line, thus promptly clearing the ice and preventing transmission line faults caused by ice accumulation.

[0034] 2. After some ice condenses on the transmission line, it becomes firmly attached to the line. When the scraper can no longer remove the ice, it stops on the surface of the transmission line. At this point, the first frame continues to slide, and the second frame slides on the first frame. After the second frame has slid a certain distance on the first frame, the contact block on the second frame contacts the limit switch and activates the servo cylinder. The servo cylinder pushes the sliding rod to slide, knocking off the ice condensed on the transmission line through the ice cone, allowing the scraper to continue moving on the transmission line.

[0035] 3. When the mounting block slides in the mounting groove, the limiting bolt slides in the long groove. After the mounting block is positioned, tighten the limiting bolt to make it abut against the side wall of the second frame, thereby fixing the mounting block in the mounting groove. Furthermore, by removing the limiting bolt from the mounting block, the mounting block can be removed from the second frame, which allows for the setting of the number of scrapers according to the actual number of transmission lines, further increasing practicality.

[0044] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0045] This application discloses a power transmission and transformation line cleaning device. (Refer to...) Figure 1 It includes a mounting bracket 1 that is slidably mounted on the transmission line and sliding brackets 2 that are slidably mounted on both sides of the mounting bracket 1.

[0046] Reference Figure 2 The fixing component 3 includes a first clamping plate 31, a second clamping plate 32, and a first driving component 33. A fixing plate 11 is fixedly installed on the mounting frame 1. One side of the first clamping plate 31 is fixedly connected to the fixing plate 11. The second clamping plate 32 is slidably installed between the mounting frame 1 and the first clamping plate 31 in a direction perpendicular to the first clamping plate 31. The second clamping plate 32 is parallel to the first clamping plate 31, and the second clamping plate 32 and the first clamping plate 31 are respectively located on both sides of the power transmission line. A guide rod 321 is fixedly installed at one end of the second clamping plate 32 near the mounting frame 1. A guide hole is opened on the mounting frame 1 in a direction perpendicular to the first clamping plate 31, and the guide rod 321 slides through the guide hole.

[0047] Reference Figure 2 The first driving component 33 includes a first cylinder, which is fixedly mounted on the mounting frame 1. The piston rod of the first cylinder is fixedly connected to the second clamping plate 32. The first clamping plate 31 has a plurality of placement grooves 311 for inserting the power transmission line at one end near the second clamping plate 32. The sidewalls of the placement grooves 311 are provided with anti-slip textures. When the mounting frame 1 is installed, the power transmission line is positioned between the first clamping plate 31 and the second clamping plate 32. When it is necessary to fix the mounting frame 1 on the power transmission line, the first cylinder is used to drive the second clamping plate 32 to slide towards the first clamping plate 31 and press the power transmission line into the placement grooves 311. The power transmission line is clamped by the first clamping plate 31 and the second clamping plate 32, thereby fixing the mounting frame 1 on the power transmission line.

[0048] Reference Figure 2 The second clamping plate 32 has multiple rotating rollers 322 rotatably mounted on one end near the first clamping plate 31. The axial directions of the multiple rotating rollers 322 are parallel, and the axial direction of the rotating rollers 322 is perpendicular to the sliding direction of the sliding frame 2. The rotating rollers 322 are used to abut against the power transmission line. Each rotating roller 322 is covered with an insulating rubber pad.

[0049] Reference Figure 1 ,3 The sliding frame 2 includes a first frame 21 and a second frame 22. Two limiting rods 12 are fixedly installed on the top wall of the mounting frame 1, and the length directions of the two limiting rods 12 are parallel. The ends of the two limiting rods 12 that are close to each other are provided with sliding grooves along the length direction of the limiting rods 12. Slider blocks are fixedly installed on both sides of the first frame 21, and the two sliders are slidably installed in the two sliding grooves respectively. Two rodless cylinders 13 are fixedly installed on the mounting frame 1. The length directions of the two rodless cylinders 13 are parallel to the length directions of the limiting rods 12. The piston of one rodless cylinder 13 is fixedly connected to one of the first frames 21, and the other rodless cylinder 13 is fixedly connected to the other first frame 21.

[0050] Reference Figure 3 , 4 Multiple guide posts 211 are fixedly installed on the first frame 21. The length direction of the multiple guide posts 211 is parallel to the length direction of the limiting rod 12. The end of the guide post 211 away from the mounting frame 1 is provided with a guide groove 2111 along the length direction of the guide post 211. Multiple support rods 221 are fixedly installed on the second frame 22. The length directions of the multiple support rods 221 are parallel, and the support rods 221 correspond one-to-one with the guide posts 211. The support rods 221 slide through the guide grooves 2111 of the guide posts 211. Limiting blocks 2211 are fixedly installed on the side wall of the support rods 221. The side wall of the guide groove 2111 is provided with a limiting groove communicating with the guide groove 2111 along the length direction of the guide post 211. The limiting blocks 2211 slide in the limiting groove.

[0051] Reference Figure 4 The first frame 21 is provided with a first elastic element 212 for driving the second frame 22 to slide away from the mounting frame 1. The first elastic element 212 includes a first compression spring. Each guide post 211 has a first compression spring in its guide groove 2111. One end of the first compression spring abuts against the bottom wall of the guide groove 2111, and the other end of the first compression spring abuts against the support rod 221.

[0052] Reference Figure 3 , 5A mounting rod 222 is fixedly installed on the second frame 22. The length direction of the mounting rod 222 is horizontal and perpendicular to the length direction of the support rod 221. The side wall of the mounting rod 222 has a mounting groove 2221 along the length direction of the mounting rod 222. A mounting block 41 is fixedly installed on the side wall of the scraper 4. The mounting block 41 is slidably installed in the mounting groove 2221. Each mounting block 41 is provided with a limiting member 42 to prevent the mounting block 41 from sliding in the mounting groove 2221. The limiting member 42 includes a limiting bolt. The mounting block 41 has a threaded hole. The limiting bolt passes through the threaded hole and is threadedly connected to the mounting block 41. The side wall of the mounting rod 222 has a long groove 2222 that communicates with the mounting groove 2221 along the length direction of the mounting rod 222. The limiting bolt is slidably installed in the long groove 2222.

[0053] The mounting block 41 is slidably set in the mounting groove 2221 of the second frame 22, which makes it easy to adjust the position of the two adjacent scraper cylinders 4 according to the distance between the two adjacent transmission lines. This prevents the position of the scraper cylinder 4 from not corresponding to the position of the transmission line, which would result in high friction between the scraper cylinder 4 and the surface of the transmission line and scratch the insulation layer of the transmission line. Furthermore, by removing the limiting bolt from the mounting block 41, the mounting block 41 and the scraper cylinder 4 can be removed from the second frame 22. This makes it easy to set the number of scraper cylinders 4 according to the actual number of transmission lines, further increasing practicality.

[0054] Reference Figure 5 The scraper cylinder 4 has an installation port 43 on its side wall. A snap fastener 44 is hinged to the scraper cylinder 4 to close the installation port 43. The scraper cylinder 4 is provided with a fixing member 45 for fixing the snap fastener 44. The fixing member 45 includes a fixing bolt. The snap fastener 44 has an installation hole. The side wall of the scraper cylinder 4 has a bolt hole that matches the fixing bolt. When the side of the snap fastener 44 away from the rotating shaft abuts against the scraper cylinder 4, the installation hole and the bolt hole are aligned. The power line is inserted into the scraper cylinder 4 through the installation port 43. Then, the installation port 43 is closed by the snap fastener 44, and the snap fastener 44 is fixed to the scraper cylinder 4 by the fixing bolt. The line cleaning device can then be installed on the power line.

[0055] Reference Figure 6 , 7 The clamping assembly 5 includes a pressure block 51, a transmission rod 52, a second elastic element 53, a pressure plate 54, and a second driving element 55. Each scraper cylinder 4 is provided with a pressure block 51. The inner wall of the scraper cylinder 4 is provided with a receiving groove. The pressure block 51 is slidably disposed in the receiving groove. The transmission rod 52 is fixedly connected to the pressure block 51. The side wall of the scraper cylinder 4 near the mounting block 41 is provided with a through hole communicating with the receiving groove. The transmission rod 52 is slidably disposed in the through hole. The end of the pressure block 51 away from the transmission rod 52 is provided with an arc-shaped groove, which is adapted to the inner wall of the scraper cylinder 4.

[0056] Reference Figure 6 , 7 The second elastic element 53 includes a second compression spring. A fixing block 521 is fixedly provided on the side wall of the transmission rod 52, and the fixing block 521 is located outside the scraper cylinder 4. The second compression spring is sleeved on the transmission rod 52. One end of the second compression spring abuts against the side wall of the scraper cylinder 4, and the other end of the second compression spring abuts against the fixing block 521. The pressure plate 54 is slidably disposed on the second frame 22 along the direction of the transmission rod 52, and the distance between each transmission rod 52 and the pressure plate 54 is equal. The second driving element 55 includes a second cylinder, which is fixedly disposed on the second frame 22. The piston rod of the second cylinder is fixedly connected to the second pressure plate 54. The pressure plate 54 is driven to slide closer to the scraper cylinder 4 by the second cylinder, so that the pressure plate 54 abuts against multiple transmission rods 52 at the same time. The pressure plate 54 continues to slide, and the transmission rod 52 drives the pressure block 51 to press against the surface of the transmission line, preventing the scraper cylinder 4 from sliding on the transmission line, thereby fixing the second frame 22 on the transmission line.

[0057] Reference Figure 6 A support frame 6 is fixed to the guide post 211 by bolts. A sliding rod 61 is slidably arranged on the support frame 6 along the length direction of the scraper cylinder 4. The sliding rod 61 is located below the scraper cylinder 4, and the length direction of the sliding rod 61 is perpendicular to the length direction of the support rod 221. Multiple ice cones 611 are fixedly arranged on the sliding rod 61. The ice cones 611 are made of stainless steel. A servo cylinder 62 is fixedly arranged on the support frame 6. The piston rod of the servo cylinder 62 is fixedly connected to the sliding rod 61. The servo cylinder 62 is electrically connected to a limit switch 621. The limit switch 621 is fixedly arranged on the guide post 211. A contact block 2212 is fixedly arranged on the support rod 221. When the limit block 2211 abuts against the side wall of the limit groove near the first frame 21, the contact block 2212 abuts against the limit switch.

[0058] After some ice condenses on the power transmission line, it becomes firmly attached to the line. When the scraper 4 has difficulty removing the ice, it stops on the surface of the power transmission line. At this time, the first frame 21 continues to slide, and the second frame 22 slides on the first frame 21. After the second frame 22 has slid a certain distance on the first frame 21, the contact block 2212 on the second frame 22 contacts the limit switch 621 and activates the servo cylinder 62. The servo cylinder 62 pushes the sliding rod 61 to slide, knocking off the ice condensed on the power transmission line through the ice cone 611, allowing the scraper 4 to continue moving on the power transmission line.

[0059] The implementation principle of the power transmission line cleaning device in this application embodiment is as follows: When ice appears on the power transmission line, the first cylinder drives the second clamping plate 32 to slide closer to the first clamping plate 31 and presses the power transmission line into the placement groove 311. The first clamping plate 31 and the second clamping plate 32 clamp the power transmission line, thereby fixing the mounting frame 1 on the power transmission line. According to the direction of ice breaking, the rodless cylinder 13 drives the first frame 21 on the side closer to the direction of ice breaking to slide, so that the scraper 4 slides on the power transmission line, thereby removing the ice on the power transmission line.

[0060] Then, the second cylinder drives the pressure plate 54 to slide closer to the scraper 4, so that the pressure plate 54 simultaneously abuts against multiple transmission rods 52. The pressure plate 54 continues to slide, and the transmission rods 52 drive the pressure block 51 to press against the surface of the transmission line, preventing the scraper 4 from sliding on the transmission line, thereby fixing the second frame 22 on the transmission line. The clamping of the first clamp 31 and the second clamp 32 on the transmission line is released, and the rodless cylinder 13 is activated to drive the mounting frame 1 to slide closer to the sliding frame 2. Then, the mounting frame 1 is fixed on the transmission line by the first clamp 31 and the second clamp 32, and the pressure block 51 is released from its pressure on the transmission line. The above steps are repeated to move the mounting frame 1 on the transmission line, thereby cleaning the ice on the transmission line in time and preventing transmission line faults caused by ice accumulation to a certain extent.

[0061] This application also discloses a construction method for a power transmission and transformation line cleaning device, including the following steps:

[0062] S1. Insert the power transmission line between the first clamping plate 31 and the second clamping plate 32. Insert the power transmission line into the scraper 4 through the mounting port 43 on the scraper 4. Then, seal the mounting port 43 with the buckle 44 and fix the buckle 44 to the scraper 4 with the fixing bolt. Install the line cleaning device on the power transmission line.

[0063] S2. The first cylinder is used to drive the second clamping plate 32 to slide closer to the first clamping plate 31 and press the power transmission line into the placement groove 311. The power transmission line is clamped by the first clamping plate 31 and the second clamping plate 32, and the mounting bracket 1 is fixed on the power transmission line.

[0064] S3. According to the direction of ice breaking, the rodless cylinder 13 drives the first frame 21 on the side closer to the direction of ice breaking to slide, so that the scraper 4 slides on the power transmission line, thereby removing the ice on the power transmission line.

[0065] S4. Then, the second cylinder drives the pressure plate 54 to slide towards the scraper 4, so that the pressure plate 54 simultaneously abuts against multiple transmission rods 52. Continue to push the pressure plate 54 to slide, and the transmission rods 52 drive the pressure block 51 to press against the surface of the power transmission line, preventing the scraper 4 from sliding on the power transmission line. Release the fixing component 3, and start the rodless cylinder 13 to drive the mounting bracket 1 to slide towards the sliding bracket 2.

[0066] S5. Then, continue to fix the mounting frame 1 on the power transmission line using the first clamp 31 and the second clamp 32, and loosen the clamping assembly 5. Repeat the above steps S3-S4 to move the mounting frame 1 on the power transmission line to clean the ice on the power transmission line.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
