Description

Technical Field

[0001] The present invention relates to the technical field of cable operation and maintenance, and particularly relates to a cable de-icing coating device and a cable de-icing coating method. Background Art

[0002] Cables include power transmission conductors, ground wires, communication cables, etc. Among them, the ground wire is usually erected above the power transmission conductor to avoid direct lightning strikes on the power transmission conductor. Therefore, the ground wire is also called a lightning protection wire. During power transmission, the heat generated by the current loss in the power transmission conductor makes the temperature of the conductor higher than that of the ground wire. Therefore, the icing situation of the power transmission conductor is not obvious, while the icing situation of the ground wire is more serious. Especially in extreme weather conditions such as ice and snow, freezing rain, etc., large-area icing of the ground wire is likely to occur, which may cause various mechanical accidents and electrical accidents, such as ground wire breakage, tower collapse, insulator flashover, etc., posing a great safety hazard to the power grid.

[0003] To solve the icing problem of cables such as power transmission conductors and ground wires, the traditional method is to first use de-icing equipment to remove the ice on the cable surface, and then use spraying equipment to spray anti-icing coating on the cable surface. Among them, for the de-icing equipment, reference can be made to the wrapped rotary de-icing mechanism of the power transmission line de-icing robot and the de-icing robot disclosed in Chinese Patent Publication No. CN115149485B, which sets a receiving cavity and a notch on the de-icing knife group to wrap the power transmission line with the de-icing knife group. When the de-icing knife group works, it can rotate and move forward to remove ice at the same time. For the spraying equipment, reference can be made to a high-altitude cable spraying system disclosed in Chinese Patent Publication No. CN109412074B, which sprays anti-icing coating on the cable through a nozzle.

[0004] Using the method of first de-icing with de-icing equipment and then spraying with spraying equipment, if the two devices are hung on the line at the same time, the load on the cable will increase, which may cause the cable to break; if the two devices are hung on the line separately, multiple up and down lines are required, and the efficiency is low.

[0005] In view of the above problems, some manufacturers have designed a device that combines de-icing and spraying functions. For example, a bare conductor de-icing coating robot disclosed in Chinese Patent Publication No. CN116247593A has a hoisting mechanism sleeved outside the storage mechanism, and an extrusion mechanism is arranged on one side of it. A front wire-walking mechanism is arranged on one side of the hoisting mechanism, and a rear wire-walking mechanism is arranged on the other side of it. A flame spraying mechanism is connected to the side of the front wire-walking mechanism away from the rear wire-walking mechanism, and a spraying mechanism is connected to the side of the rear wire-walking mechanism away from the front wire-walking mechanism. The spraying mechanism is communicated with the storage mechanism through a pipeline. The front wire-walking mechanism and the rear wire-walking mechanism walk on the bare conductor, and the flame spraying mechanism and the spraying mechanism of the robot body on the line can be controlled by a wireless remote controller offline. The flame spraying mechanism melts the ice on the surface of the bare conductor in front of the moving robot and burns obstacles, and the spraying mechanism sprays insulating anti-icing coating on the surface of the bare conductor behind the moving robot.

[0006] A mobile high-altitude cable de-icing device mentioned above combines a flame spraying mechanism and a coating mechanism. During actual operation, de-icing with the flame spraying mechanism is likely to damage the cable, and the ice melting process is relatively slow, resulting in low efficiency of the entire operation process.

[0007] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0046] Advantages of the present invention:

[0047] 1. The cable ice removal and coating device and the cable ice removal and coating method of the present application can cooperate with the drone to achieve automatic online and offline. Before going online, hook the boom of the drone to the hanging component, use the remote control to control the drone to hang the entire cable ice removal and coating device on the cable, and use the drone for online and offline operations, and the operation method is more flexible.

[0048] 2. It is provided with a rotary ice removal mechanism, a vibration ice removal mechanism, and a coating mechanism; after going online, as the traveling mechanism travels on the cable, during the traveling process, the thick ice layer on the cable is removed by the rotary ice removal mechanism, then the thin ice layer on the cable is removed by the vibration ice removal mechanism, and finally the anti-icing coating is coated on the cable by the coating mechanism; the rotary ice removal mechanism and the vibration ice removal mechanism are used in combination for ice removal, and the removal effect of the ice layer on the cable surface is better. After ice removal is completed, the anti-icing coating is coated on the cable by the coating mechanism, and the coating effect of the anti-icing coating is better; ice removal is performed first and then coating is achieved on the same device, without the need to use two devices, with high integration and good coherence, and the coating effect of the anti-icing coating is better.

[0063] Embodiment 1

[0064] Please refer to Figures 1 to 8 , a cable de-icing and coating device of this embodiment includes a frame 10, a traveling mechanism 40, a rotary de-icing mechanism 50, a vibration de-icing mechanism 60 and a coating mechanism 70. An inlet and outlet wire groove 11 for the cable 30 to enter or exit is provided at the lower end of the frame 10.

[0065] For the cable de-icing coating device of this embodiment, a hanging component 20 is connected to the upper end of the frame 10, which can cooperate with a drone to realize automatic online and offline operations. Before going online, hang the boom of the drone on the hanging component 20, and use the remote control to control the drone to hang the entire cable de-icing coating device on the cable 30. Use the drone for online and offline operations, and the operation method is more flexible.

[0066] Moreover, a rotary de-icing mechanism 50, a vibration de-icing mechanism 60, and a coating mechanism 70 are sequentially arranged along the traveling direction of the traveling mechanism 40; after going online, as the traveling mechanism 40 travels on the cable 30, the thick ice layer 32 of the cable 30 is removed by the rotary de-icing mechanism 50 during the traveling process, and then the thin ice layer 31 of the cable 30 is removed by the vibration de-icing mechanism 60. Finally, the anti-icing coating is applied to the cable 30 by the coating mechanism 70; in this application, the rotary de-icing mechanism 50 and the vibration de-icing mechanism 60 are used in combination for de-icing, and the removal effect of the ice coating on the surface of the cable 30 is better. After de-icing is completed, the anti-icing coating is applied to the cable 30 by the coating mechanism 70. De-icing and then coating are realized on the same device, without the need to use two devices, with high integration, good coherence, and better coating effect of the anti-icing coating.

[0067] As Figure 2 and Figure 4 shown, the traveling mechanism 40 includes a front rotating shaft 41, a front traveling wheel 42, a rear rotating shaft 43, and a rear traveling wheel 44. Both the front rotating shaft 41 and the rear rotating shaft 43 are rotatably arranged on the frame 10. The front traveling wheel 42 is arranged on the front rotating shaft 41, and the rear traveling wheel 44 is arranged on the rear rotating shaft 43. The front traveling wheel 42 travels on the thin ice layer 31 of the cable 30, and the rear traveling wheel 44 travels on the cable 30.

[0068] As Figure 5 shown, the rotary de-icing mechanism 50 is located on the front side of the traveling direction of the front traveling wheel 42 and is used to remove the thick ice layer 32 of the cable 30. The rotary de-icing mechanism 50 includes a mounting seat 51 fixed to the frame 10, a worm gear seat 52 rotatably arranged on the mounting seat 51, a rotary drive assembly 53 for driving the worm gear seat 52 to rotate circumferentially around the cable 30, a cutter head 54 connected to the front side of the worm gear seat 52 and having a first opening 541 at the bottom, and at least three cutter heads 55 arranged at intervals along the circumference on the cutter head 54. The distance between the cutting edge of the cutter head 55 and the cable 30 is adjustable, which can adapt to the de-icing operation of cables 30 with different diameters.

[0069] The working principle of the rotary de-icing mechanism 50 is as follows: After the cable 30 enters the de-icing channel inside the cutter head 54 through the first opening 541 of the cutter head 54, the distance between the cutting edge of the cutter head 55 and the cable 30 is first reduced, but the cutting edge of the cutter head 55 cannot touch the surface of the cable 30 to avoid scratching the cable 30. Then, the rotary drive assembly 53 is turned on, and the rotary drive assembly 53 drives the worm gear seat 52 and the cutter head 54 to rotate circumferentially around the cable 30. During the walking process, the thick ice layer 32 on the cable 30 is scraped off by the cutter head 55 of the cutter head 54.

[0070] As Figure 4 shown, the vibration de-icing mechanism 60 is located between the front walking wheel 42 and the rear walking wheel 44 and is used to remove the thin ice layer 31 on the cable 30. The vibration de-icing mechanism 60 includes a first linkage assembly 61, a first rotating shaft 62, a first eccentric hammer 63, a second rotating shaft 64, and a second eccentric hammer 65. The first rotating shaft 62 and the second rotating shaft 64 are both rotatably arranged on the frame 10 and are synchronously driven by the first linkage assembly 61. The first eccentric hammer 63 is connected to the first rotating shaft 62, and the second eccentric hammer 65 is connected to the second rotating shaft 64. The first eccentric hammer 63 and the second eccentric hammer 65 are respectively located on both radial sides of the cable 30 and both reciprocally hammer the thin ice layer 31 on the cable 30 in the direction of the cable 30.

[0071] The working principle of the vibration de-icing mechanism 60 is as follows: The first linkage assembly 61 synchronously drives the first rotating shaft 62 and the second rotating shaft 64. The first rotating shaft 62 drives the first eccentric hammer 63 to rotate, and the second rotating shaft 64 drives the second eccentric hammer 65 to rotate. The first eccentric hammer 63 and the second eccentric hammer 65 reciprocally hammer the thin ice layer 31 on the cable 30 in the direction of the cable 30. The thin ice layer 31 on the cable 30 is removed by hammering, so that the surface of the cable 30 is exposed, and thus the subsequent anti-icing coating can better adhere to the surface of the cable 30.

[0072] As Figure 1 and Figure 3 shown, the coating mechanism 70 is located at the rear side in the walking direction of the rear walking wheel 44 and is used to coat the anti-icing coating on the cable 30. The coating mechanism 70 includes a spraying seat 71, a spray head 72, a material pumping pump 73, and a storage tank 74. The spraying seat 71 is fixed to the frame 10 and is provided with a spraying channel 711 with an open bottom. The cable 30 passes through the spraying channel 711. The spray head 72 is fixed to the spraying seat 71 and is arranged towards the spraying channel 711. The material pumping pump 73 is used to pump the anti-icing coating in the storage tank 74 to the spray head 72 and then spray it out from the spray head 72, so that the anti-icing coating is coated on the surface of the cable 30, achieving the effect of preventing secondary icing on the surface of the cable 30.

[0073] Furthermore, please refer to Figure 4, the hanging component 20 includes a cross bar 21 fixed to the frame 10, a vertical plate 22 fixed to the cross bar 21, and a hook 24 detachably fixed to the vertical plate 22 through a locking member 23. One end of the card slot of the hook 24 is connected with a downwardly inclined guide plate 25. When using a drone for hanging, the hanging rod of the drone can be quickly guided into the card slot of the hook 24 through the guide plate 25, realizing the quick positioning of the hanging rod.

[0074] Furthermore, please refer to Figure 4 , the cable de-icing coating device further includes a second linkage component 80. The second linkage component 80 includes a first motor 81, a first pulley 82, a second pulley 83, and a first transmission belt 84. The first pulley 82 is in transmission connection with the front rotating shaft 41, the second pulley 83 is in transmission connection with the rear rotating shaft 43, and the first pulley 82 and the second pulley 83 are in transmission connection through the first transmission belt 84. After the first motor 81 is started, the first motor 81 directly drives the rear rotating shaft 43 to rotate. One end of the rear rotating shaft 43 is connected with the second pulley 83, and the second pulley 83 drives the first pulley 82 to rotate through the first transmission belt 84. The first pulley 82 then drives the rotating shaft 41 to rotate, thereby realizing the synchronous rotation of the front traveling wheels 42 and the rear traveling wheels 44. The front traveling wheels 42 and the rear traveling wheels 44 can share the power output of the first motor 81, saving the number of motors and reducing the overall weight.

[0075] Furthermore, please refer to Figure 5 , the rotary drive component 53 includes a second motor 531, a first worm 532, a second worm 533, a worm gear 534, a third pulley 535, a fourth pulley 536, and a second transmission belt 537. The lower end of the worm gear 534 has a second opening 5341. The second motor 531 is fixed to the mounting seat 51. The output shaft of the second motor 531 is in transmission connection with the first worm 532. The first worm 532 and the second worm 533 are both in meshing connection with the worm gear 534. The third pulley 535 is in transmission connection with the first worm 532, the fourth pulley 536 is in transmission connection with the second worm 533, and the third pulley 535 and the fourth pulley 536 are in transmission connection through the second transmission belt 537. In this embodiment, due to the second opening 5341 at the lower end of the worm gear 534, the tooth profile is incomplete. If a single worm is used, the meshing stroke will be disconnected. However, in this application, the first worm 532 and the second worm 533 are respectively arranged on both sides of the worm gear 534, and the two worms are respectively used for compensation, which can well solve this problem.

[0076] The working principle of the rotary drive assembly 53 is as follows: After the second motor 531 starts, it directly drives the first worm 532 and the third pulley 535 to rotate. The third pulley 535 drives the fourth pulley 536 to rotate through the second transmission belt 537, thereby driving the second worm 533 to rotate. Both the first worm 532 and the second worm 533 are meshed and connected to the worm gear 534, enabling the worm gear 534 to rotate circumferentially around the cable 30. One end of the worm gear 534 is fixed to the worm gear seat 52, and the worm gear seat 52 is also connected to the cutter head 54, so that the cutter head 54 rotates circumferentially around the cable 30. When the traveling mechanism 40 travels, the cutter head 55 of the cutter head 54 rotates to scrape off the thick ice layer 32 of the cable 30.

[0077] Further, please refer to Figures 5 to 7 , the cutter head 55 of this embodiment has three, and the rotary deicing mechanism 50 further includes a centering assembly 56. The centering assembly 56 includes an arc-shaped groove 561, a limit post 562, a waist-shaped hole 563, a positioning post 564, a telescopic driver 565, three swing arms 566 and three pulleys 567; the arc-shaped groove 561 is provided on the cutter head 54, one end of the limit post 562 is fixed to the worm gear seat 52 and can move along the arc-shaped groove 561, the other end of the limit post 562 is hinged to the housing of the telescopic driver 565, and the telescopic part of the telescopic driver 565 is hinged to the cutter head 54; the waist-shaped hole 563 is provided on the swing arm 566, the positioning post 564 is fixed to the cutter head 54 and moves in the waist-shaped hole 563. The middle of the swing arm 566 is hinged to the cutter head 54 through a rotating shaft 568. The end of the swing arm 566 away from the cable 30 is movably connected to the cutter head 54 through the positioning post 564 and the waist-shaped hole 563, and the other end is connected with the cutter head 55 and the pulley 567; before the cable 30 is strung, the cutter head 55 can be adjusted to the initial state as shown in Figure 6 . The three cutter heads 55 and the three pulleys 567 are in a contracted state, and the first opening 541 of the cutter head 54 is adjusted downward so that the cable 30 can enter the deicing channel inside the cutter head 54 along the first opening 541 of the cutter head 54; after the stringing is completed, the telescopic driver 565 is started, and the telescopic driver 565 is used to drive the cutter head 54 to rotate relative to the worm gear seat 52. The rotation of the cutter head 54 drives the swing arm 566 to rotate around the rotating shaft 568, so that the three cutter heads 55 and the three pulleys 567 swing towards the deicing channel inside the cutter head 54 to the state as shown in Figure 7 . The three pulleys 567 clamp the cable 30 inside the deicing channel, and then the three rotating cutter heads 55 are used to remove the thick ice layer 32 of the cable 30.

[0078] Further, the pulley 567 and the cutter head 55 on the same swing arm 566 are arranged in sequence along the length direction of the cable 30. Through the positioning function of the pulley 567, the cutter head 55 is prevented from contacting the cable 30, better protecting the cable 30.

[0079] Further, please refer to Figure 4, the first linkage assembly 61 of this embodiment includes a cross plate 611, a third motor 612, a fifth pulley 613, a sixth pulley 614, and a third transmission belt 615. The cross plate 611 is fixed to the frame 10. The third motor 612 is fixed to the cross plate 611 and is in transmission connection with the second rotating shaft 64. The fifth pulley 613 is in transmission connection with the first rotating shaft 62. The sixth pulley 614 is in transmission connection with the second rotating shaft 64. The fifth pulley 613 and the sixth pulley 614 are in transmission connection through the third transmission belt 615. By driving the first rotating shaft 62 and the second rotating shaft 64 to rotate simultaneously through the third motor 612, the first eccentric hammer 63 and the second eccentric hammer 65 can share the power output of the third motor 612, saving the number of motors and reducing the overall weight.

[0080] Furthermore, in order to improve the removal effect of the thin ice layer 31 on the surface of the cable 30, a plurality of arc-shaped protrusions are provided on the surfaces of the first eccentric hammer 63 and the second eccentric hammer 65 of this embodiment.

[0081] Please refer to Figure 3 , there are three spray nozzles 72 in this embodiment. The three spray nozzles 72 are arranged at equal intervals in the circumferential direction on the spraying seat 71, improving the coating uniformity.

[0082] Please refer to Figure 3 , first hollow plates 12 and second hollow plates 13 are respectively provided at the lower ends on both sides of the frame 10 along the radial direction of the cable 30. The material pumping pump 73 and the storage tank 74 are both fixed to the first hollow plate 12. By adopting the design of the first hollow plate 12 and the second hollow plate 13, the wind resistance on both sides of the frame 10 and the overall weight can be reduced, avoiding excessive left and right swaying amplitude of the cable de-icing and coating device due to too large crosswind resistance during the wire hanging de-icing and coating process.

[0083] Furthermore, please refer to Figure 3 , the battery 14 is detachably fixed to the frame 10. The battery 14 is located below the second hollow plate 13. The battery 14 on the left side and the material pumping pump 73 and the storage tank 74 on the right side form a left-right balance structure, which can prevent tipping over.

[0084] As Figure 8 shown, this embodiment also discloses a cable de-icing and coating method, including the following steps:

[0085] S1 Preparation before the device is put on the line, including:

[0086] S11 Fill the anti-icing coating into the storage tank 74 and adjust the spraying seat 71 to face downward with the opening;

[0087] S12 Adjust the cutter head 55 to the initial state and adjust the first opening 541 of the cutter disc 54 to face downward;

[0088] S13 Adjust the relative distance between the first eccentric hammer 63 and the second eccentric hammer 65 to the maximum;

[0089] The S2 UAV suspension device includes:

[0090] S21 Hang the boom of the UAV on the suspension assembly 20;

[0091] S22 Use the remote control to control the UAV to hang the entire cable de-icing and coating device on the cable 30;

[0092] S3 Initial position de-icing, including:

[0093] S31 Adjust the distance between the cutting edge of the cutter head 55 and the cable 30 to be smaller;

[0094] S32 Start the rotary de-icing mechanism 50, then start the traveling mechanism 40 to move forward a certain distance to rotate and scrape off the thick ice layer 32 in front;

[0095] S33 After scraping, a thin ice layer 31 is formed on the surface of the cable 30. At this time, the front traveling wheel 42 travels on the thin ice layer 31 of the cable 30;

[0096] S4 Traveling de-icing and coating, including:

[0097] S41 Start the rotary de-icing mechanism 50 and the vibration de-icing mechanism 60. During the traveling process, the rotary de-icing mechanism 50 clears the thick ice layer 32 on the cable 30;

[0098] S42 The vibration de-icing mechanism 60 reciprocally hammers the thin ice layer 31 on the cable 30 in the direction of the cable 30 to make the thin ice layer 31 on the surface of the cable 30 fall off;

[0099] S43 Start the coating mechanism 70. During the traveling process, the coating mechanism 70 coats the anti-icing coating on the cable 30;

[0100] S5 Lower the line, including:

[0101] S51 When all the ice on the cable 30 is cleared, adjust the distance between the cutting edge of the cutter head 55 and the cable 30 to be larger, adjust the cutter head 55 to the initial state, adjust the first opening 541 of the cutter disc 54 to face downwards, adjust the opening of the spraying seat 71 to face downwards, and adjust the relative distance between the first eccentric hammer 63 and the second eccentric hammer 65 to the maximum;

[0102] S52 Remotely control the UAV to lift and lower, so that the boom of the UAV is re-hung on the suspension assembly 20;

[0103] S53 Use the remote control to control the UAV to recover the entire cable de-icing and coating device.

[0104] A cable de-icing and coating method according to this embodiment realizes automatic loading and unloading by using a drone. Before loading, the boom of the drone is hung on the hanging assembly 20, and the remote control is used to control the drone to hang the entire cable de-icing and coating device on the cable 30. The use of the drone for loading and unloading makes the operation mode more flexible. After loading is completed, as the traveling mechanism 40 travels on the cable 30, the thick ice layer 32 on the cable 30 is removed by the rotary de-icing mechanism 50 during the traveling process, and then the thin ice layer 31 on the cable 30 is removed by the vibration de-icing mechanism 60. Finally, the coating mechanism 70 coats the anti-icing coating on the cable 30. This application uses the rotary de-icing mechanism 50 and the vibration de-icing mechanism 60 to cooperate for de-icing, and the removal effect of the ice coating on the surface of the cable 30 is better. After de-icing is completed, the coating mechanism 70 is used to coat the anti-icing coating on the cable 30. De-icing and then coating are realized on the same device, without the need to use two devices, with high integration and good coherence, and the coating effect of the anti-icing coating is better.
