Description

Technical Field

[0001] This invention belongs to the field of power line maintenance technology, specifically relating to a de-icing equipment traction device for overhead conductors and its usage method. Background Technology

[0002] In frigid climates, overhead power transmission lines are highly susceptible to increased loads due to icing, leading to serious accidents such as conductor galloping, line breaks, and even tower collapses, threatening power grid safety. To remove icing, various de-icing equipment (such as de-icing robots and de-icing crawlers) is typically used to move along the conductors and perform de-icing operations. However, how to safely, efficiently, and reliably install de-icing equipment from the ground onto the suspended conductors (i.e., the "online" process) is the first and most crucial technical challenge faced in actual operation and maintenance. Currently, common methods for bringing de-icing equipment online include: 1. Manual climbing: Operators climb to the towers and manually install or drop de-icing equipment onto the conductors. This method is not only labor-intensive and inefficient, but also carries a high risk of falling from heights and is severely limited by weather and terrain conditions, resulting in poor safety. 2. Using drones to carry equipment and drop it onto the conductors. While this method avoids manual climbing, it is greatly affected by wind and weather conditions, making it difficult to guarantee dropping accuracy and easily causing equipment failure, damage, or even collisions with the conductors. Meanwhile, drones are complex to operate, require highly skilled pilots, and have limited endurance. Patent publication number CN113036704B discloses an auxiliary traction device for de-icing high-altitude high-voltage cables in power engineering. This device includes a connecting plate with a battery fixedly mounted on its bottom surface and an mounting plate fixed to one end. Through the arrangement of multiple steel wire belts and heating tubes, the heated steel wire belts melt the ice layer on the cable at their contact point and embed themselves within the ice, preventing slippage between the steel wire belts and the cable. Rollers drive the steel wire belts, ensuring that each outer surface of the steel wire belt contacts the side of the cable. While the technical solution disclosed in the aforementioned patent provides guidance to some extent, its guiding structure is fixed at an angle or has a limited adjustment range, making it difficult to accurately match the complex and ever-changing height and position of the conductor on-site, leading to difficulties in alignment. Furthermore, it lacks an integrated and controllable traction and release system, relying on manual experience during the alignment process, resulting in poor stability and controllability. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a de-icing equipment traction device for overhead power lines and its usage method, thereby solving the technical problems mentioned in the background art.

[0004] The objective of this invention is achieved as follows: a tilting de-icing equipment traction device for traction of de-icing equipment onto an overhead power line to remove ice, comprising: a tilting guide mechanism, including a support frame with an adjustable tilt angle and a guide rail disposed on the top of the support frame, wherein a housing is detachably disposed within the guide rail, and an arc-shaped guide groove parallel to the extension direction of the power line is provided on one side of the housing, the curvature of the arc-shaped guide groove being adapted to the outer diameter of the power line, for connecting the power line and guiding the de-icing equipment to slide along the direction of the power line; a flexible traction mechanism, including a traction rope, a drive unit, and a locking assembly, wherein one end of the traction rope is connected to the de-icing equipment, and the other end is wound around the drum of the drive unit, and the locking assembly is used to releasably fix the de-icing equipment to the initial position of the guide rail; and an angle adjustment mechanism, including a base connected to the bottom of the support frame, wherein a telescopic rod is fixedly disposed on the upper surface of the base, the upper end of the telescopic rod being ball-jointed with the middle part of the support frame, and the tilt angle of the support frame is adjusted by the extension and retraction of the telescopic rod, so that the entrance end of the guide rail is aligned with the power line.

[0005] A tilting guide mechanism provides a smooth, angle-adjustable transition track for the de-icing equipment from the ground to the air. An angle adjustment mechanism, like a robotic arm, flexibly adjusts the track's inclination to precisely align its entry point with overhead power lines at different heights. Finally, a flexible traction mechanism acts as a safety rope and power source. These three components work together to transform the originally high-risk vertical hoisting or throwing process into a controllable, sloping sliding ascent. During implementation, the device is moved below the work point, and the telescopic rod of the angle adjustment mechanism is operated to tilt the support frame until the entry end of the guide track aligns with the overhead power line. The de-icing equipment is then placed at the starting end of the guide track (the lower end) and temporarily secured with a locking component. One end of the traction rope is reliably connected to the de-icing equipment. This completely avoids the risks of operators climbing at heights or the complex operations of drones. The ascent is smooth and precise; the guide track physically constrains and guides the equipment, ensuring "soft contact" between the equipment and the power line, preventing impact damage. It is highly versatile, and the angle-adjustable mechanism allows one set of equipment to adapt to lines of different voltage levels (i.e., different heights), improving equipment utilization.

[0006] Furthermore, a material layer, namely polytetrafluoroethylene (PTFE) or ultra-high molecular weight polyethylene (UHMW-PE) coating, is applied to the inner surface of the arc-shaped guide groove. By adding a material with an extremely low coefficient of friction to the inner surface of the equipment sliding channel (arc-shaped guide groove), the sliding friction resistance between the equipment and the track is minimized. During the manufacturing of the guide track, a Teflon (PTFE) or ultra-high molecular weight polyethylene (UHMW-PE) coating is applied to the surface of the arc-shaped guide groove by spraying, pasting, or hot pressing. The extremely low friction results in minimal scratching force on the conductors when the equipment is online, effectively protecting the coating or stranded structure on the surface of the conductors. This leads to smoother equipment sliding, lower required traction force, reduced power demand of the drive unit, and a more stable online process.

[0007] Furthermore, the entrance end of the guide rail is equipped with a flared guide nozzle, the width of which gradually decreases along the guiding direction. An array of balls is located on its inner side to reduce frictional resistance when the de-icing equipment enters. The flared guide nozzle forms a funnel-shaped entrance, allowing the equipment to be smoothly "guided" into the rail even if there is a slight initial misalignment. The inner ball array transforms the sliding friction between the equipment and the entrance into rolling friction, further reducing starting resistance. This allows operators to quickly place the de-icing equipment into the rail without precise alignment. The balls significantly reduce the maximum static friction force at the moment the equipment begins to slide from a standstill, preventing start-up jams or vibrations and ensuring a smoother initial setup.

[0008] Furthermore, the drive unit is an electric winch or a hydraulic motor, with a torque sensor and an encoder on its drum. The torque sensor detects the tension of the traction rope, and the encoder records the release length of the traction rope. When the controller detects a sudden drop in the tension of the traction rope, it can automatically determine that the equipment has successfully slid into the guide wire and switch the working mode (stop releasing and switch to traction movement). Through encoder feedback, the movement distance of the equipment on the guide wire can be precisely controlled, enabling fixed-point de-icing or inter-section reciprocating operations.

[0009] Furthermore, the locking component is an electromagnetic chuck or a mechanical caliper, which incorporates a wireless communication module. This module receives control commands via wireless signals to remotely separate the de-icing device from the guide rail. The locking mechanism is remotely triggered via wireless signals (such as a remote control or mobile app), ensuring a safe separation between the operator and the device. In practice, the wireless receiving module, such as Bluetooth, LoRa, or 4 / 5G, is integrated into the control circuit of the electromagnetic chuck or electromechanical caliper. The operator sends a command from a safe position, activating a relay to power on (engage) or deactivate (release) the locking mechanism. The operator can release the device from a distance, completely avoiding potential risks during the device's initiation and gliding, eliminating the need for manual unlocking and simplifying the operation.

[0010] Furthermore, it also includes an anti-derailment mechanism, comprising anti-derailment baffles and pressure sensors symmetrically arranged on the upper and lower sides of the guide rail. The height of the anti-derailment baffles is adjustable, and they have an elastic buffer layer inside. The pressure sensors are embedded inside the anti-derailment baffles to detect the contact pressure between the de-icing equipment and the anti-derailment baffles. By setting physical barriers on both sides of the track, the equipment is prevented from derailing under bumpy conditions. The baffle height is adjustable to accommodate de-icing equipment of different sizes.

[0011] Furthermore, the de-icing equipment includes a support frame and a de-icing assembly. The de-icing assembly includes a de-icing section with an arc-shaped de-icing surface, on which a retractable tip and a heating device are provided. In practice, for hard ice, the tip is extended to impact and break the ice layer; for wet snow or thin ice, the heating device (such as a resistance wire or PTC) is activated to melt the junction between the ice layer and the wire, causing the ice to fall off. This combines mechanical ice breaking and thermal ice melting, effectively addressing different types and thicknesses of ice accumulation, improving the reliability and efficiency of de-icing.

[0012] Furthermore, the de-icing unit is connected to the support via an electric push rod. The base of the electric push rod is fixed to the side of the support, and the telescopic end of the electric push rod is fixedly connected to the outer surface of the de-icing unit. When the electric push rod extends or retracts, it drives the tip of the de-icing unit to pierce the ice layer outside the conductor. By directly converting the linear extension and retraction of the electric push rod into a "piercing" action with the tip perpendicular to the conductor, the electric push rod is controlled to extend rapidly, driving the tip to pierce the ice layer, and then retract, repeating this process to achieve "hammering" ice breaking. By controlling the current or stroke of the electric push rod, the force and depth of the tip's impact can be precisely controlled, avoiding damage to the conductor.

[0013] A method for using a tilting de-icing equipment traction and mounting device, used to implement the aforementioned traction and mounting device, includes the following steps: Step 1: Adjusting the tilt angle by using a telescopic rod to adjust the tilt angle of the support frame so that the entrance end of the guide rail is aligned with the guide wire, and fixed to the ground by a base; Step 2: Installing the de-icing equipment by placing the de-icing equipment in the initial position of the guide rail and temporarily fixing it by a locking component; Step 3: Traction and mounting by moving the de-icing equipment onto the guide wire via the guide rail; Step 4: During the de-icing operation, the de-icing equipment is pulled along the guide wire by a traction rope. In Step 4, the heating device of the de-icing component is adjusted according to the ice thickness: when the ice thickness is ≥ a first preset value, the heating device is activated, where the first preset value is 20 mm.

[0014] Before or during operation, ice thickness information is obtained through sensors or manual measurement. When the thickness reaches or exceeds 20 mm (the first preset value), the controller automatically activates the heating device to participate in de-icing. When the thickness is below this threshold, only mechanical methods or a lower power mode are used, avoiding unnecessary activation of the heating function in cases of thin ice or no ice, thus saving energy.

[0015] The beneficial effects of this invention are as follows: By combining tilting guidance with flexible traction, semi-automated safe deployment of de-icing equipment is achieved, reducing the risks of manual high-altitude operations. The tilting guidance mechanism provides the de-icing equipment with a smooth, angle-adjustable transition track from the ground to the air; the angle adjustment mechanism, like a "robotic arm," flexibly adjusts the tilt angle of this track, ensuring its entrance is precisely aligned with overhead conductors at different heights; finally, the flexible traction mechanism acts as a safety rope and power source. These three components work together to transform the originally high-risk vertical hoisting or throwing process into a controllable inclined sliding deployment. During implementation, the device is moved below the work point, the telescopic rod of the angle adjustment mechanism is operated to drive the support frame to tilt until the entrance end of the guide track is aligned with the overhead conductor. The de-icing equipment is then placed at the starting end of the guide track (the lower end) and temporarily secured with a locking component. One end of the traction rope is reliably connected to the de-icing equipment. It completely avoids the risks of operators climbing at heights or the complex operations of drones. The system ensures smooth and precise deployment, with a guide rail providing physical constraints and guidance to guarantee "soft contact" between the equipment and the conductors, preventing impact damage. Its high versatility and adjustable angle mechanism allow one unit to adapt to lines of different voltage levels (i.e., different heights), improving equipment utilization. The de-icing equipment features a flexible and adjustable ice-breaking method, effectively handling ice of varying thicknesses and improving de-icing efficiency. Attached Figure Description

It should be noted that all directional terms such as up, down, front, back, left, and right appearing in this invention are... Figure 1 The diagram is for reference only, and all directional terms are not intended to limit the invention, but are merely for clearer explanation and interpretation. Example 1

[0019] like Figure 1-8 As shown, this embodiment discloses a tilting de-icing equipment traction device for traction of de-icing equipment onto an overhead conductor 22 to remove ice. It includes: a tilting guide mechanism comprising an adjustable tilt angle support frame 1 and a guide rail 2 disposed on top of the support frame 1; a detachable housing 3 is disposed within the guide rail 2; one side of the housing 3 is provided with an arc-shaped guide groove 4 parallel to the conductor's extension direction; the curvature of the arc-shaped guide groove 4 is adapted to the outer diameter of the conductor, used to connect the conductor and guide the de-icing equipment to slide along the conductor direction; and a flexible traction mechanism. It includes a traction rope 5, a drive unit 6, and a locking assembly 7. One end of the traction rope 5 is connected to the de-icing device, and the other end is wound around the drum 8 of the drive unit 6. The locking assembly 7 is used to releasably fix the de-icing device to the initial position of the guide rail 2. The angle adjustment mechanism includes a base 9 connected to the bottom of the support frame 1. A telescopic rod 10 is fixedly installed on the upper surface of the base 9. The upper end of the telescopic rod 10 is ball-jointed with the middle part of the support frame 1. The tilt angle of the support frame 1 is adjusted by the extension and retraction of the telescopic rod 10 so that the entrance end of the guide rail 2 is aligned with the guide wire.

[0020] A tilting guide mechanism provides a smooth, angle-adjustable transition track for the de-icing equipment from the ground to the air. An angle adjustment mechanism, like a robotic arm, flexibly adjusts the track's inclination to precisely align its entrance with the overhead conductor 22 at different heights. Finally, a flexible traction mechanism acts as a safety rope and power source. These three components work together to transform the originally high-risk vertical hoisting or throwing process into a controllable, sloping sliding ascent. During implementation, the device is moved below the work point, and the telescopic rod 10 of the angle adjustment mechanism is operated to tilt the support frame 1 until the entrance end of the guide track 2 is aligned with the overhead conductor 22. The de-icing equipment is then placed at the starting end of the guide track 2 (the lower end) and temporarily secured with the locking component 7. One end of the traction rope 5 is reliably connected to the de-icing equipment. It completely avoids the risks of operators climbing at heights or complex drone operations. The system is stable and precise. The guide rail 2 provides physical constraints and guidance for the equipment, ensuring "soft contact" between the equipment and the conductor, avoiding impact damage. It is highly versatile, and the adjustable angle mechanism allows one set of devices to adapt to lines of different voltage levels (i.e., different heights), improving equipment utilization.

[0021] For better performance, a material layer 11, which is a polytetrafluoroethylene (PTFE) or ultra-high molecular weight polyethylene (UHMW-PE) coating, is applied to the inner surface of the arc-shaped guide groove 4. By adding a material with an extremely low coefficient of friction to the inner surface of the equipment sliding channel (arc-shaped guide groove 4), the sliding friction resistance between the equipment and the track is minimized. During the manufacturing of the guide track 2, a Teflon (PTFE) or ultra-high molecular weight polyethylene (UHMW-PE) coating is applied to the surface of the arc-shaped guide groove 4 by spraying, pasting, or hot pressing. The extremely low friction results in minimal scratching force on the conductors when the equipment is online, effectively protecting the coating or stranded structure on the surface of the conductors. This makes the equipment slide more smoothly, requires less traction force, reduces the power demand of the drive unit 6, and makes the online process more stable.

[0022] For better results, the inlet end of the guide rail 2 is equipped with a flared guide nozzle 12, the width of which gradually decreases along the guiding direction. An inner ball bearing array 13 is provided to reduce frictional resistance when the de-icing equipment enters. The flared guide nozzle 12 forms a funnel-shaped inlet, allowing the equipment to be smoothly "guided" into the rail even if there is a slight initial misalignment. The inner ball bearing array 13 transforms the sliding friction between the equipment and the inlet into rolling friction, further reducing starting resistance. This allows operators to quickly place the de-icing equipment into the rail without precise alignment. The ball bearings significantly reduce the maximum static friction force at the moment the equipment begins to slide from a standstill, preventing start-up jams or vibrations and ensuring a smoother initial setup.

[0023] For better performance, the drive unit 6 is an electric winch or a hydraulic motor, and its drum 8 is equipped with a torque sensor 14 and an encoder 15. The torque sensor 14 is used to detect the tension of the traction rope 5, and the encoder 15 is used to record the release length of the traction rope 5. When the controller detects a sudden drop in the tension of the traction rope 5, it can automatically determine that the equipment has successfully slid into the conductor and switch the working mode (stop releasing and switch to traction movement). Through the feedback of the encoder 15, the movement distance of the equipment on the conductor can be precisely controlled to achieve fixed-point de-icing or inter-section reciprocating operation.

[0024] For better results, the locking component 7 is an electromagnetic chuck or a mechanical caliper, with an internal wireless communication module. This module receives control commands via wireless signals to remotely separate the de-icing device from the guide rail 2. The locking mechanism is remotely triggered via wireless signals (such as a remote control or mobile app), ensuring a safe separation between the operator and the device. In practice, the wireless receiving module, such as Bluetooth, LoRa, or 4 / 5G, is integrated into the control circuit of the electromagnetic chuck or electromechanical caliper. The operator sends a command from a safe position, activating a relay to power on (engage) or deactivate (release) the locking mechanism. The operator can release the device from a distance, completely avoiding potential risks during the device's initiation and gliding, eliminating the need for manual unlocking and simplifying the operation. Example 2

[0025] like Figure 1-8 As shown, this embodiment, based on embodiment 1, further includes an anti-detachment mechanism, which includes anti-detachment baffles 16 symmetrically arranged on the upper and lower sides of the guide rail 2 and pressure sensors 17. The height of the anti-detachment baffles 16 is adjustable, and an elastic buffer layer is provided inside. The pressure sensors 17 are embedded inside the anti-detachment baffles 16 to detect the contact pressure between the de-icing equipment and the anti-detachment baffles 16. By setting physical barriers on both sides of the rail, the equipment is prevented from derailing under bumpy conditions. The height of the baffles 16 is adjustable to accommodate de-icing equipment of different sizes.

[0026] For better results, the de-icing equipment includes a support frame and a de-icing assembly. The de-icing assembly includes a de-icing section 18 with an arc-shaped de-icing surface. The arc-shaped de-icing surface is equipped with a retractable tip 19 and a heating device 20. In operation, for hard ice, the tip 19 is extended to impact and break the ice layer; for wet snow or thin ice, the heating device 20 (such as a resistance wire or PTC) is activated to melt the junction between the ice layer and the wire, causing the ice to fall off. This combination of mechanical ice breaking and thermal ice melting effectively addresses different types and thicknesses of ice, improving the reliability and efficiency of de-icing.

[0027] For better results, the de-icing section 18 is connected to the support via an electric push rod 21. The base of the electric push rod 21 is fixed to the side of the support, and the telescopic end of the electric push rod 21 is fixedly connected to the outer surface of the de-icing section 18. When the telescopic rod 10 of the electric push rod 21 extends or retracts, it drives the tip 19 of the de-icing section 18 to pierce the ice layer outside the conductor. By directly converting the linear extension and retraction of the electric push rod 21 into a "piercing" action of the tip 19 perpendicular to the conductor, the electric push rod 21 is controlled to extend quickly, driving the tip 19 to pierce the ice layer, and then retract, repeating this process to achieve "hammering" ice breaking. By controlling the current or stroke of the electric push rod 21, the force and depth of the tip 19's impact can be precisely controlled, avoiding damage to the conductor.

[0028] A method for using a tilting de-icing equipment traction and mounting device, used to implement the aforementioned traction and mounting device, includes the following steps: Step 1: Adjusting the tilt angle by using a telescopic rod 10 to adjust the tilt angle of the support frame 1 so that the entrance end of the guide rail 2 is aligned with the guide wire, and fixed to the ground by the base 9; Step 2: Installing the de-icing equipment by placing the de-icing equipment in the initial position of the guide rail 2 and temporarily fixing it by a locking component 7; Step 3: Pulling the equipment onto the guide wire by using the guide rail 2; Step 4: During the de-icing operation, the de-icing equipment is pulled along the guide wire by a traction rope 5. In Step 4, the heating device 20 of the de-icing component is adjusted according to the ice thickness: when the ice thickness is ≥ a first preset value, the heating device 20 is activated, where the first preset value is 20 mm.

[0029] Before or during operation, ice thickness information is obtained through sensors or manual measurement. When the thickness reaches or exceeds 20 mm (the first preset value), the controller automatically activates the heating device 20 to participate in de-icing. When the thickness is below this threshold, only mechanical methods or a lower power mode are used, avoiding unnecessary activation of the heating function in cases of thin ice or no ice, thus saving energy.

[0030] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present invention, should be covered within the scope of protection of the present invention.
