Description

Technical Field

[0001] The invention belongs to the field of overhead lines, and in particular relates to a hydrophobic anti-icing coating repair device for overhead lines. Background Art

[0002] Patent 202110820385.6 discloses a self-repairing anti-icing aluminum stranded wire with composite holes and a preparation method thereof, which first etches small holes on the surface of the aluminum conductor, and then coats a layer of low-surface-energy material on the surface of the aluminum conductor to achieve a hydrophobic and anti-icing effect. However, low-surface-energy materials are mostly liquid organic substances, such as siloxanes, fluorinated silanes, polyolefins, etc. The overhead lines are exposed in the air. Under the influence of rain, dust, sunlight and other factors, these low-surface-energy liquids will slowly degrade, and it is difficult for them to remain on the surface of the conductor for a long time. As the low-surface-energy liquid decreases, the hydrophobic and anti-icing effect of the overhead lines slowly disappears. Assuming that the overhead lines are at high altitudes, it is difficult to re-coat the low-surface-energy liquid after it is lost. Relying on manual re-coating is a huge workload, and high-altitude operations are hard, dangerous and inefficient.

[0003] Patent CN2020222885501 discloses an integrated lightweight anti-interference coating robot, and patent CN2019217871154 discloses an electric coating machine for insulation treatment of overhead bare wires. This coating equipment can only be used for coating between line towers and cannot cross obstacles. Workers need to frequently unload and mount the coating machine between line towers, which is inefficient.

[0004] Patent CN2015104170580 discloses a line patrol and deicing robot and its obstacle crossing method, and patent CN2019208638841 discloses a high-voltage overhead line walking device. There are many similar line patrol robots that can cross obstacles between towers or high-voltage line walking devices that can cross obstacles. However, there has been no report on an efficient device or method that can cross the fixed points of overhead line towers for uninterrupted coating. Summary of the Invention

[0010] Preferably, one of the inclined plates is provided with a square notch, and the high-pressure coating device includes an arc-shaped plate, which is located in the square notch, and a coating nozzle is provided on the arc-shaped plate, the coating nozzle faces downward, and a pump is fixedly connected to one side of the coating cylinder, a water suction pipe is connected between the pump and the inner cavity of the coating cylinder, and an elastic output pipe is connected between the pump and the coating nozzle.

[0011] Preferably, the arc plate is located in the square notch on the inclined plate and is rotatably connected to the inclined plate. A torsion spring is provided at the connection between the arc plate and the inclined plate. The bottom surface of the arc plate is fixedly connected to the round rod. The side of the coating cylinder close to the round rod is fixedly connected to the mounting bracket. One side of the mounting bracket is fixedly connected to the first motor. The main shaft of the first motor passes through the mounting bracket. The outer circle of the main shaft of the first motor is fixedly connected to the circular block. One side of the circular block is fixedly connected to the arc block. The arc block is located on one side of the round rod.

[0012] Preferably, the two sides of the coating cylinder are fixedly connected to the first box body and the second box body respectively, and the side walls of the first box body, the second box body and both sides of the coating cylinder are provided with square through grooves. The inner wall of the first box body is rotatably connected to the first rotating rod, and the outer circle of the first rotating rod is wrapped around the filter cloth, and the filter cloth is located above the low surface energy material.

[0014] Preferably, a counterweight is fixedly connected to a side of the coating cylinder away from the first motor, the first motor and the counterweight are respectively located on two sides of the coating cylinder, and the counterweight is used to keep the coating cylinder balanced.

[0015] Technical effects and advantages of the present invention: The hydrophobic anti-icing coating repair device for overhead lines proposed by the present invention has the following advantages over the prior art:

[0016] Each time one of the travel wheels detaches from the overhead line, the remaining three travel wheels continue to hang on the overhead line to provide support and forward power, so that the repair device is more stable when passing the connection point, and avoids the repair device losing support and falling.

[0017] 2. The present invention sets an arc-shaped guide plate. After the first walking wheel passes the connection position, the servo motor drives the semicircular plate to rotate in the direction close to the overhead line and reset it to the state of being hung on the overhead line again. During this process, due to the shaking of the overhead line, the position deviation of the walking wheel and the overhead line cannot be aligned. At this time, the overhead line will contact the arc-shaped guide plate. As the arc-shaped guide plate continues to squeeze the overhead line, the overhead line will slide along the arc-shaped guide plate toward the walking wheel until the walking wheel is hung on the overhead line. At this time, the first obstacle avoidance walking device has passed the connection point. By setting the arc-shaped guide plate, the repair device can more conveniently make the walking wheel contact the overhead line again and make the walking wheel move along the overhead line again.

[0018] 3. The present invention provides a filter cloth, and the first motor drives the circular block to contact one end of the round rod, and the arc block pushes the round rod, so that the arc plate rotates a certain angle to avoid the connection point. At the same time, the main shaft of the first motor drives the second rotating rod to rotate and rewind the filter cloth through the first pulley and the second pulley, so that the position originally located directly below the coating nozzle moves when the second rotating rod rotates to rewind the filter cloth, and is misaligned with the coating nozzle, so as to avoid a large amount of dust particles accumulating on the surface of the filter cloth directly below the coating nozzle, thereby reducing the filtering effect of the filter cloth. After the filter cloth with a large amount of dust accumulation is displaced, the new filter cloth is moved to directly below the coating nozzle to ensure the filtering effect of the filter cloth. After that, after the arc plate and the walking wheel pass the connection point, the repair device will only pull the filter cloth to move when it passes the line tower connection point, and replace the filter cloth to the position below the nozzle. Such an arrangement will not lead to too frequent replacement of the filter cloth, which will affect the filtering effect of the filter cloth. At the same time, since the repair device is at a high altitude when working, it is inconvenient to replace the low surface energy material. Impurities entrained by the low surface energy material in the coating cylinder are coated by filtering. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] like Figure 1-7As shown, a hydrophobic anti-icing coating repair device for overhead lines includes a coating barrel 1, which stores a low-surface-energy material. Two obstacle-avoiding running devices 2 are mounted on either side of the barrel, and the obstacle-avoiding running devices 2 are hung on the overhead line. Both sides of the barrel are fixedly connected to horizontal plates 12, which are staggered on either side of the barrel. Two obstacle-avoiding running devices 2 are mounted on each horizontal plate 12, and the four obstacle-avoiding running devices 2 are staggered in pairs. The upper surface of the barrel is fixedly connected to two inclined plates 11, one of which is equipped with a high-pressure coating device 3.

[0028] This device is used to flush and coat the overhead line. The device is hung on the overhead line by a crane. At this time, four obstacle-avoiding walking devices 2 are hung on the overhead line. The four obstacle-avoiding walking devices 2 move forward along the overhead line. When moving forward, the high-pressure coating device 3 flushes and coats the overhead line. Two inclined plates 11 are located on both sides of the coating cylinder 1, which act as baffles to prevent water from splashing to both sides. After the low surface energy material flushes the overhead line, the dust on the overhead line is washed down and falls into the coating cylinder 1. When the device reaches the position of the line tower, there is a connection point between the overhead line and the line tower at this position, such as Figure 2 At 100 in the figure, an obstacle is formed to the forward movement of the device. At this time, the four obstacle-avoiding walking devices 2 pass over the connection point and continue to move forward. The four obstacle-avoiding walking devices 2 are located on both sides of the coating cylinder 1. The weight of the device is evenly distributed, so that the device can maintain balance. The obstacle-avoiding walking device 2 passes over the connection point, so that the device can pass through the line tower for continuous coating, without frequent disassembly and installation, which is conducive to improving coating efficiency, saving time, and simple operation. After the coating is completed, the device is removed again by a crane.

[0029] The obstacle avoidance walking device 2 includes a vertical plate 21, one side of the vertical plate 21 is fixedly connected to the servo motor 22, the main shaft of the servo motor 22 passes through the vertical plate 21, one end of the main shaft of the servo motor 22 is fixedly connected to the swing rod 23, one end of the swing rod 23 is fixedly connected to the semicircular plate 24, the inner arc surface of the semicircular plate 24 is fixedly connected to two mounting plates 25, one side of one mounting plate 25 is fixedly connected to the drive motor 26, the main shaft of the drive motor 26 passes through the two mounting plates 25 and is rotatably connected to the two mounting plates 25, the outer circle of the main shaft of the drive motor 26 is fixedly connected to the walking wheel 27, the four walking wheels 27 are located above the coating cylinder 1, the four walking wheels 27 are arranged in a linear array, the inner arc surfaces of the four semicircular plates 24 are fixedly connected to two arc guide plates 28, and the two arc guide plates 28 are located on both sides of the walking wheel 27.

[0030] The crane hoists the device to the height of the overhead line. After the device is hung on the overhead line, the four running wheels 27 are pressed against the same overhead line. The repair device is powered by a rechargeable lithium battery or an external ground power supply vehicle. At this time, the high-voltage coating device 3 coats the overhead line, and the low-surface-energy material falls into the coating cylinder 1. As the device advances, the four drive motors 26 simultaneously drive the four running wheels 27, causing them to advance along the overhead line. The device is equipped with four drive motors 27 to drive the four running wheels 27 to rotate, increasing the driving force of the device.

[0031] When the device moves to the tower position, the running wheel 27 moves to the connection position between the overhead line and the tower, and the four running wheels 27 are arranged linearly. At this time, the servo motor 22 in the first obstacle avoidance running device 2 closest to the connection position drives the semicircular plate 24 to rotate in the direction away from the overhead line through the swing rod 23, so that the running wheel 27 closest to the connection position rotates away from the overhead line, so that the semicircular plate 24 is turned from a horizontal state to a vertical state, so that the semicircular plate 24 and the running wheel 27 can avoid the overhead line. At this time, the remaining three running wheels 27 are still hanging on the overhead line, providing support for the device and driving the repair device forward a distance, so that the first running wheel 27 passes the connection position;

[0032] After the first running wheel 27 passes the connection position, the servo motor 22 drives the semicircular plate 24 to rotate in the direction close to the overhead line and reset it to the state of being hung on the overhead line again. During this process, due to the shaking of the overhead line, the running wheel 27 and the overhead line may not be aligned. At this time, the overhead line will contact the arc-shaped guide plate 28. As the arc-shaped guide plate 28 continues to squeeze the overhead line, the overhead line slides along the arc-shaped guide plate 28 toward the running wheel 27 until the running wheel 27 is hung on the overhead line. At this time, the first obstacle avoidance running device 2 has passed the connection point;

[0033] The remaining three running wheels 27 repeat the above process and rotate in turn to avoid. Every time one running wheel 27 detaches from the overhead line, the remaining three running wheels 27 continue to hang on the overhead line to provide support and forward power, so that the repair device can pass the connection point more smoothly, avoiding the repair device from losing support and falling, until all four running wheels 27 pass the connection point on the tower, and continue the overhead line coating operation. After the coating operation is completed, the repair device is removed by a crane.

[0034] One of the inclined plates 11 is provided with a square notch, and the high-pressure coating device 3 includes an arc-shaped plate 31, which is located in the square notch. A coating nozzle 32 is provided on the arc-shaped plate 31, and the coating nozzle 32 faces downward. One side of the coating cylinder 1 is fixedly connected to the pump 33, and a water suction pipe 34 is connected between the pump 33 and the inner cavity of the coating cylinder 1, and an elastic output pipe 35 is connected between the pump 33 and the coating nozzle 32. The arc-shaped plate 31 is located in the square notch on the inclined plate 11 and is rotatably connected to the inclined plate 11. A torsion spring is provided at the connection between the arc-shaped plate 31 and the inclined plate 11. The bottom surface of the arc-shaped plate 31 is fixedly connected to the round rod 4, and the side of the coating cylinder 1 close to the round rod 4 is fixedly connected to the mounting bracket 41. One side of the mounting bracket 41 is fixedly connected to the first motor 42. The main shaft of the first motor 42 passes through the mounting bracket 41. The outer circle of the main shaft of the first motor 42 is fixedly connected to the circular block 43, and one side of the circular block 43 is fixedly connected to the arc block 44. The arc block 44 is located on one side of the round rod 4.

[0035] The crane hangs the repair device on the overhead line. At this time, the four running wheels 27 are hung on the overhead line. The four running wheels 27 move along the overhead line. At the same time, the pump 33 pumps the low surface energy material in the coating cylinder 1 through the water pumping pipe 34, and flushes it downward on the overhead line through the elastic output pipe 35 and the coating nozzle 32. The coating nozzle 32 is located in the middle position of the four running wheels 27. When it reaches the tower position, the two running wheels 27 on one side of the coating nozzle 32 rotate to avoid the connection point under the drive of the servo motor 22. After that, it is hung on the overhead line again under the action of the servo motor 22. At this time, the first motor 42 drives the circular block 43 to rotate. When the arc block 44 on the circular block 43 contacts one end of the round rod 4, the arc block 44 pushes the round rod 4, causing the arc plate 31 to rotate a certain angle around the connection position of the arc plate 31 and the inclined plate 11 as the center of the circle. , so that the curved plate 31 rotates away from the overhead line, so that the curved plate 31 drives the coating nozzle 32 away from the overhead line. At this time, the repair device is still in a forward state until the curved plate 31 passes the line tower connection point. The first motor 42 drives the curved plate 31 to continue to rotate, so that the curved block 44 is out of contact with the round rod 4. Under the action of the torsion spring, the curved plate 44 reverses back to above the overhead line, and the curved plate 44 drives the coating nozzle 32 back to above the overhead line. After that, the remaining two walking wheels 27 pass the connection point and continue to move forward to coat the overhead line. By setting the curved plate 31, the rotation of the curved plate 31 can avoid the line tower joint, so that the repair device can continuously coat the overhead line. At the same time, the curved plate 31 can prevent low-surface-energy materials from splashing upward. The low-surface-energy materials fall into the coating cylinder 1 and can be reused to avoid waste.

[0036] The two sides of the coating cylinder 1 are fixedly connected to the first box body 5 and the second box body 51 respectively. The side walls of the first box body 5, the second box body 51 and both sides of the coating cylinder 1 are provided with square through-grooves. The inner wall of the first box body 5 is rotatably connected to the first rotating rod 52. The outer circle of the first rotating rod 52 is wrapped with a filter cloth 53. The filter cloth 53 is located above the low surface energy material. The inner wall of the second box body 51 is rotatably connected to the second rotating rod 54. The filter cloth 53 passes through the coating cylinder 1 through the through-groove and is connected to the outer circle of the second rotating rod 54. The second rotating rod 54 passes through the second box body 51. One end of the main shaft of the first motor 42 is fixedly connected to the first pulley 55, and one end of the second rotating rod 54 is fixedly connected to the second pulley 56. The second pulley 56 is located on the outside of the second box body 51. A belt is connected between the first pulley 55 and the second pulley 56. The side of the coating cylinder 1 away from the first motor 42 is fixedly connected to the counterweight 58. The first motor 42 and the counterweight 58 are respectively located on both sides of the coating cylinder 1. The counterweight 58 is used to keep the coating cylinder 1 balanced.

[0037] The crane hangs the repair device on the overhead line, and the four running wheels 27 move forward along the overhead line. At the same time, the pump 33 extracts the low-surface-energy material in the coating cylinder 1 through the water pumping pipe 34, and sprays it downward on the overhead line through the elastic output pipe 35 and the coating nozzle 32 to achieve coating. The dust, bird droppings and other debris on the overhead line are filtered when passing through the filter cloth 53. The dust and bird droppings fall on the surface of the filter cloth 53, so that the low-surface-energy material in the coating cylinder 1 below the filter cloth 53 remains clean, so that the low-surface-energy material coating the overhead line is a clean low-surface-energy material. When the tower position is reached, the first motor 42 drives the circular block 43 to contact one end of the round rod 4, and the arc block 44 pushes the round rod 4, causing the arc plate 31 to rotate a certain angle to avoid the connection point. At the same time, the main shaft of the first motor 42 drives the first pulley 55 to rotate, and the first pulley 55 drives the second pulley 56 to rotate through the belt, so that the second rotating rod 54 rotates to reel in the filter cloth 53, so that the position originally located directly below the coating nozzle 32 moves when the second rotating rod 54 rotates to reel in the filter cloth 53, forming a misalignment with the coating nozzle 32, thereby preventing a large amount of dust particles from accumulating on the surface of the filter cloth 53 directly below the coating nozzle 32, thereby reducing the filtering effect of the filter cloth 53. After the filter cloth 53 with a large amount of dust accumulated is displaced, the new filter cloth 53 moves to the bottom of the coating nozzle 32 to ensure the filtering effect of the filter cloth 53. After that, after the curved plate 31 and the walking wheel 27 pass the connection point, the repair device continues to coat the overhead line;

[0038] The repair device will only pull the filter cloth 53 to move when it passes the connection point of the line tower. The replacement filter cloth 53 is located below the nozzle. Such a setting will not cause the filter cloth 5 to be replaced too frequently, affecting the filtering effect of the filter cloth 53. At the same time, since the repair device is at a high altitude when working, it is inconvenient to replace the low-surface energy material. The low-surface energy material in the coating cylinder 1 is kept clean by filtering. There is no need to remove the repair device to replace the clean low-surface energy material, which is more convenient and quick. As the second rotating rod 54 rotates to rewind the filter cloth 53, the particles on the filter cloth 53 will fall into the second box body 51 for collection. After the coating operation is completed, the repair device is removed and the staff will coat the particles, which is more environmentally friendly.

[0039] When in use, the repair device is hung on the overhead line by a crane. After the four running wheels 27 are hung on the overhead line, the pump 33 pumps the low surface energy material in the coating cylinder 1 through the pumping pipe 34, and flushes it downward onto the overhead line through the elastic output pipe 35 and the coating nozzle 32. The four drive motors 26 simultaneously drive the four running wheels 27 to move forward along the overhead line. When it reaches the tower position, the running wheels 27 move to the connection position between the overhead line and the tower. At this time, the servo motor 22 in the first obstacle avoidance running device 2 closest to the connection position drives the semicircular plate 24 to rotate in the direction away from the overhead line through the swing rod 23, so that the running wheel 27 closest to the connection position rotates away from the overhead line so that the semicircular plate 24 and the running wheel 27 can avoid the overhead line. At this time, the remaining three running wheels 27 are still hanging on the overhead line, providing support for the repair device while driving the repair device forward a distance, so that the first running wheel 27 passes the connection position and is hung on the overhead line again. When the two running wheels 27 on one side of the coating nozzle 32 are on the servo motor The second travel wheel 27 repeats the above process and rotates and avoids in turn until the repair device has completely passed the line tower connection point, and then the repair device continues to travel along the overhead line and coat the overhead line.
