Description

Technical Field

[0001] This invention relates to the field of overhead line technology, and in particular to an overhead line surface coating brushing device that can cross obstacles. Background Technology

[0002] Patent 202110820385.6 discloses a self-healing anti-icing aluminum stranded wire with composite holes and its preparation method. The method involves first etching small holes into the surface of the aluminum conductor, and then coating the surface with a low surface energy material to achieve a liquid-repellent and anti-icing effect. However, low surface energy materials are mostly liquid organic compounds, such as siloxanes, fluorinated silanes, polyolefins, etc. Overhead lines are exposed to the air, and under the influence of rain, dust, and sunlight, these low surface energy liquids will slowly degrade, making it difficult for them to remain on the conductor surface for long periods. As the low surface energy liquid decreases, the liquid-repellent and anti-icing effect of the overhead line gradually disappears. Since overhead lines are located at high altitudes, it is difficult to recoat them after the low surface energy liquid is depleted. Manual recoating is labor-intensive, dangerous, and inefficient.

[0003] Patent CN2020222885501 discloses an integrated lightweight anti-interference coating robot, and patent CN2019217871154 discloses a power coating machine for insulation treatment of overhead bare conductors. This coating equipment can only coat between online towers and cannot cross obstacles. It requires workers to frequently unload and reload the coating machine between online towers, which is inefficient.

[0004] Patent CN2015104170580 discloses a line inspection and de-icing robot and its obstacle-crossing method, and patent CN2019208638841 discloses a high-voltage overhead line walking device.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] Example 1

[0026] like Figure 1-6As shown, the present invention provides an overhead line surface coating brushing device that can overcome obstacles, including a support base 1, with clamping and walking devices 2 on both sides of the support base 1. The clamping and walking devices 2 can clamp the overhead line 10 and walk independently. A coating box 3 is fixedly connected to the upper side of the support base 1, and a diagonal support rod 11 is fixedly connected to one side of the support base 1. A camera 12 is fixedly connected to the upper end of the diagonal support rod 11. A solar panel 13 is fixedly connected to the outside of the coating box 3 for using solar energy. The coating box 3 is equipped with a lithium battery, which powers the entire device for independent operation. An obstacle avoidance groove 4 is provided on the upper side of the coating box 3. Frames 5 are slidably connected to opposite sides of the obstacle avoidance groove 4. Folded rubber covers 6 are fixedly connected to the inner walls of the frames 5 and the obstacle avoidance groove 4. Semi-conical sleeves 7 are fixedly connected to opposite sides of the two frames 5. A sponge block 71 is fixedly connected to the inner side of the small end of one of the semi-conical sleeves 7.

[0027] The coating box 3 cleans and coats a single overhead line 10. When encountering a tower, the connection between the overhead line 10 and the tower is difficult to cross. One of the clamping and traveling devices 2 is released, and the other clamping and traveling device 2 suspends the entire device and moves it over the obstacle. After the previously released clamping and traveling device 2 is repositioned, the overhead line 10 re-enters the clearance groove 4. The two frames 5 are driven closer by electric push rods. The two frames 5 approach each other and stretch and fold the rubber cover 6 to cover the clearance groove 4 to prevent liquid splashing. The semi-conical sleeves 7 of the two frames 5 merge to form a conical sleeve, which is fitted onto the overhead line 10. The large end of the conical sleeve passes through the overhead line 10, and the small end of the conical sleeve facilitates cleaning and wiping the overhead line 10.

[0028] A support rod 41 is fixedly connected to the inner wall of the clearance groove 4. An arc plate 42 is fixedly connected to the end of the support rod 41. A sliding groove 43 is provided on the inner arc surface of the arc plate 42. An arc plate 44 is slidably connected in the sliding groove 43. A rubber plate 45 is fixedly connected to one end of the arc plate 44 and the sliding groove 43. The rubber plate 45 plays the role of elastic support. The inner arc surface of the arc plate 44 is provided with bristles.

[0029] The bottom of the clearance trough 4 is provided with a groove 411, and the bottom of the groove 411 is provided with a drain hole 412. A filter screen 413 is provided inside the drain hole 412. A circulating liquid pump 414 is fixedly connected to one side of the coating box 3. A nozzle 415 is provided on the inner wall of the clearance trough 4. The inlet pipe of the circulating liquid pump 414 is connected to the drain hole 412, and the outlet pipe of the circulating liquid pump 414 is connected to the nozzle 415. The low surface energy liquid is sprayed onto the overhead line 10 through the nozzle 415. The sprayed low surface energy liquid is covered by the unfolded folded rubber cover 6. The low surface energy liquid flows into the drain hole 412 and is filtered through the filter screen 413. The circulating liquid pump 414 pumps the low surface energy liquid in the drain hole 412 back into the nozzle 415 for spraying. It can be recycled and reused without carrying a large amount of low surface energy liquid, so as to continuously spray and improve the uninterrupted coating capability.

[0030] The overhead line 10 is generally made of multiple strands of aluminum wire twisted together. There is a groove 20 between two adjacent aluminum wires. After the bristles of the arc plate 44 pass over the surface, due to the action of the twisted groove 20, the bristles move along the twisted groove 20 first. When the rubber plate 45 is compressed to the limit, the elastic bristles produce a bending effect, detach from one of the grooves 20 and enter the adjacent groove 20 to start the next cycle. The bristles on the arc plate 44 brush the low surface energy liquid into the groove 20 to improve the coating effect of the outer surface of the overhead line 10.

[0031] Each clamping and walking device 2 includes a rotating rod 21, which is hinged to the side of the support base 1. One end of an electric push rod 22 is hinged to both sides of the support base 1, and the other end of the electric push rod 22 is hinged to the rotating rod 21. The end of the rotating rod 21 is fixedly connected to the first motor 23, and the main shaft of the first motor 23 is fixedly connected to the walking box 8.

[0032] When overcoming obstacles, the clamping and traveling device 2 on one side of the forward direction releases its grip on the overhead line 10. Simultaneously, the two electric push rods 22 on both sides of the support base 1 work together to cause the coating box 3 to detach from the overhead line 10. The rear clamping and traveling device 2 moves forward. After the front clamping and traveling device 2 crosses the obstacle, the two electric push rods 22 work together to cause the front clamping and traveling device 2 to grip the overhead line 10. Then, the rear clamping and traveling device 2 releases, and the front clamping and traveling device 2 continues to move. Finally, the two electric push rods 22 work together again to reset the clamping and traveling device 2 and the coating box 3. During this process, the camera 12 observes remotely. The above actions are completed remotely, enabling the device to operate continuously and easily avoid towers, thus facilitating continuous operation.

[0033] The traveling box 8 includes a box body 81 with an open structure at the top and on both sides. Two support wheels 82 are rotatably connected inside the box body 81. A traveling motor 83 is fixedly connected to the outside of the box body 81. The main shaft of the traveling motor 83 is coaxially fixedly connected to one of the support wheels 82. An inclined guide rail 84 is fixedly connected to the upper part of one side of the box body 81. A sliding sleeve 85 is slidably connected to the inclined guide rail 84. A pressure plate 86 is fixedly connected to one side of the sliding sleeve 85. Two pressing wheels 87 are rotatably connected to the bottom of the pressure plate 86. The pressing wheels 87 are correspondingly arranged with the support wheels 82. An electric push rod 88 is fixedly connected to one side of the box body 81. The telescopic rod of the electric push rod 88 is fixedly connected to the sliding sleeve 85. One of the support wheels 82 is controlled by the traveling motor 83 to travel on the overhead line 10. The overhead line 10 is clamped between the pressing wheel 87 and the support wheel 82. When it is necessary to detach, the pressing wheel 87 moves obliquely upward along the inclined guide rail 84 to avoid the overhead line 10, so that the traveling box 8 can quickly detach from the overhead line 10.

[0034] Working principle: After one of the clamping and walking devices 2 is released, the other clamping and walking device 2 suspends the entire device and moves it over the obstacle. The previously released clamping and walking device 2 is then repositioned, and the overhead line 10 re-enters the clearance groove 4. The two frames 5 are driven to approach each other by electric push rods. The two frames 5 approach each other and stretch and fold the rubber cover 6 to cover the clearance groove 4 to prevent liquid splashing. The semi-conical sleeves 7 of the two frames 5 are combined to form a conical sleeve, which is fitted onto the overhead line 10. The large end of the conical sleeve passes through the overhead line 10, and the small end of the conical sleeve facilitates cleaning and wiping of the overhead line 10.
