Description

Technical Field

[0001] This invention relates to the field of power facility maintenance technology, and in particular to a de-icing device for power transmission towers. Background Technology

[0002] In cold regions, power transmission lines are prone to icing. Excessive ice buildup increases conductor load, leading to increased conductor sag, galloping, and even serious accidents such as line breaks and tower collapses, threatening power grid safety. Current technologies commonly employ de-icing methods including manual knocking, thermal melting, and mechanical de-icing.

[0003] Existing mechanical de-icing devices have poor adjustment flexibility and are difficult to adapt to cables of different diameters. They are also prone to damaging the cable surface during the de-icing process, failing to meet the core requirements of adaptability and cable protection, which greatly troubles the de-icing operation of power transmission tower cables. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a power tower de-icing device that can safely and efficiently de-ic cables of different diameters.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A power tower de-icing device includes: a traveling mechanism, an adjusting mechanism, and a de-icing mechanism;

[0007] The walking mechanism has a cable penetration cavity;

[0008] The adjustment mechanism is installed on the walking mechanism;

[0009] The de-icing mechanism is mounted on the walking mechanism; the de-icing mechanism includes at least two de-icing components, which are arranged facing each other; each de-icing component includes a clamping plate, an ice-knocking rod, and a drive source; the adjusting mechanism drives and connects two clamping plates belonging to different de-icing components, so that the two clamping plates can move closer to each other to clamp the cable, and can move further apart to release the cable; the ice-knocking rod belonging to the same de-icing component is slidably connected to the clamping plate, so that two ice-knocking rods belonging to different de-icing components can move closer to each other or further apart; in the same de-icing component, the drive source is mounted on the clamping plate and drives and connects to the ice-knocking rod, and is used to drive the ice-knocking rod to slide relative to the clamping plate.

[0010] Furthermore, the power tower de-icing device also includes a control system and a vision detection module. The vision detection module is installed on the walking mechanism and is used to detect changes in the position of the cable passing through the penetration cavity. The control system is electrically connected to the vision detection module, the de-icing mechanism, the walking mechanism, and the adjustment mechanism.

[0011] Furthermore, the adjustment mechanism includes an angle adjustment motor, a swing frame, and a tension / opening drive motor; the angle adjustment motor is mounted on the walking mechanism, drives the swing frame, and is used to change the angle between the swing frame and the horizontal plane; the tension / opening drive motor is mounted on the swing frame, and drives two clamping plates belonging to different de-icing components to be connected, so that the two clamping plates can approach each other to clamp the cable, and can move away from each other to release the cable.

[0012] Furthermore, the direction from the rear of the walking mechanism to the front of the walking mechanism is defined as the forward direction of the walking mechanism; the power tower de-icing device further includes a rotating support base, which has a supporting part and a rotating part. The rotating part is rotatably connected to the walking mechanism so that the supporting part is located in front of or behind the walking mechanism. The adjusting mechanism is installed on the supporting part to follow the rotation of the supporting part.

[0013] Furthermore, the rotating support is connected to a counterweight.

[0014] Furthermore, the swing frame is provided with an arc-shaped limiting groove, the center of which coincides with the swing center of the swing frame. The supporting part of the rotating support seat is provided with a limiting rod, which extends into the arc-shaped limiting groove. The limiting rod is provided with a limiting key, which is used to limit the limiting rod from falling out of the arc-shaped limiting groove. The limiting rod slides in conjunction with the arc-shaped limiting groove.

[0015] Furthermore, the opening and closing drive motor is mounted on the swing frame via a telescopic drive device, which includes a telescopic drive rod and a support plate. The telescopic drive rod is mounted on the swing frame, drives and connects to the support plate, and supports the support plate. The opening and closing drive motor is mounted on the support plate.

[0016] Furthermore, the support plate is provided with a guide rod, which extends toward the swing frame and is movably inserted through the swing frame.

[0017] Furthermore, the opening and closing drive motor drives two clamping plates belonging to different de-icing components via a transmission assembly. The transmission assembly includes a first drive shaft, a first drive gear, a second drive shaft, and a second drive gear. The first drive shaft is connected to the opening and closing drive motor. The first drive gear is sleeved on the first drive shaft. The first drive gear and the second drive gear are mutually geared and bonded, and the number of teeth of the first drive gear is equal to the number of teeth of the second drive gear. The second drive gear is sleeved on the second drive shaft. The first drive shaft and the second drive shaft are respectively mounted on the swing frame via mounting brackets. The two clamping plates belonging to different de-icing components are respectively connected to swing rods, and each swing rod is respectively sleeved on one of the first drive shaft and the second drive shaft to rotate with it.

[0018] Furthermore, the de-icing assembly also includes a push-pull plate, and multiple ice-knocking rods are provided, belonging to the same de-icing assembly. Each ice-knocking rod is connected to the push-pull plate, and the push-pull plate is driven by the drive source.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. Based on the adjustment mechanism, two clamping plates belonging to different de-icing components are connected, allowing the two clamping plates to approach each other to clamp the cable and to move away from each other to release the cable. This allows for flexible control of the clamping plates' opening and closing via the adjustment mechanism. During hanging, the plates are fully open to avoid interference with the cable, and after hanging, they are closed to wrap around the cable. This also adapts to the clamping requirements of cables of different diameters, eliminating the need for dedicated devices for different cable specifications, improving the device's versatility, reducing operating costs, and ensuring strong clamping, thus guaranteeing the relative stability of the device and the cable during de-icing.

[0021] 2. The ice-knocking rod belonging to the same de-icing assembly is slidably connected to the clamping plate, so that two ice-knocking rods belonging to different de-icing assemblies can move closer or further apart from each other; the ice-knocking rod can reciprocate under the action of the driving source. This design can form a precise impact through the opposing movements of the ice-knocking rods of different de-icing assemblies, which can efficiently peel off the ice covering the cable surface. Compared with traditional de-icing methods, the impact force is controllable, the de-icing is highly targeted, and damage to the cable body is avoided, thus balancing de-icing efficiency and cable protection.

[0022] 3. Based on the fact that the walking mechanism has a cable penetration cavity; the adjustment mechanism is installed on the walking mechanism; and the de-icing mechanism is installed on the walking mechanism, the coordination of each mechanism is strengthened. The walking mechanism can drive the entire device to move smoothly along the cable. With the continuous operation of the de-icing mechanism, the cable can be de-iced evenly throughout its entire length. There is no need for manual climbing of the tower. It can be combined with deployment methods such as drone hoisting to greatly reduce the risk of high-altitude operations, improve the safety and coverage of de-icing operations, and reduce manpower input and operation time.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] See Figures 1-4 A preferred embodiment of the present invention provides a de-icing device for power transmission towers, comprising: a traveling mechanism 1, an adjusting mechanism 2, and a de-icing mechanism 3;

[0032] The walking mechanism 1 has a cable penetration cavity 11;

[0033] The adjustment mechanism 2 is installed on the walking mechanism 1;

[0034] The de-icing mechanism 3 is installed on the walking mechanism 1; the de-icing mechanism 3 includes at least two de-icing components 31, which are arranged facing each other; each de-icing component 31 includes a clamping plate 311, an ice-knocking rod 312, and a drive source 313; the adjusting mechanism 2 drives and connects two clamping plates 311 belonging to different de-icing components 31, so that the two clamping plates 311 can approach each other to clamp the cable, and can move away from each other to release the cable; the ice-knocking rod 312 belonging to the same de-icing component 31 is slidably connected to the clamping plate 311, so that two ice-knocking rods 312 belonging to different de-icing components 31 can approach or move away from each other; in the same de-icing component 31, the drive source 313 is installed on the clamping plate 311 and drives and connects the ice-knocking rod 312, and is used to drive the ice-knocking rod 312 to slide relative to the clamping plate 311.

[0035] The working principle of this invention is as follows: Before operation, the de-icing device is hoisted using equipment such as a drone. During hoisting, the adjusting mechanism 2 adjusts the de-icing mechanism 3 to a fully open state, ensuring that the two clamping plates 311 belonging to different de-icing components 31 are far apart from each other, avoiding interference between the device and the cable during hoisting. This facilitates the stable hoisting of the device to the target cable position and its placement on the cable (i.e., the cable passes through the cable penetration cavity 11 of the walking mechanism 1). After hoisting, the adjusting mechanism 2 is activated and drives the two clamping plates 311 to move closer together until they tightly clamp the cable, causing the de-icing mechanism 3 to close and completely wrap around the cable. Simultaneously, relying on the driving action of the adjusting mechanism 2, it can adapt to cables of different diameters, achieving precise adjustment of clamping force and wrapping range. During de-icing operations, the adjusting mechanism 2 drives the clamping plates 311 of each de-icing component 31 to move closer together, clamping the cable and working with the ice-breaking rods 312 to peel off the cable surface. When the traveling mechanism 1 encounters ice on the cable surface and cannot move forward, the adjusting mechanism 2 drives the clamping plates 311 of each de-icing component 31 to move further apart, releasing the cable. Then, the driving source 313 of each de-icing component 31 drives the ice-breaking rods 312, which are slidably connected to the clamping plates 311 of each de-icing component 31, to move. This causes the two ice-breaking rods 312 belonging to different de-icing components 31 to move closer and further apart, forming a reciprocating impact action on the cable surface, effectively knocking off the ice on the cable surface. When the ice on the cable surface that is preventing the progress is removed, the adjusting mechanism 2 again drives the clamping plates 311 of each de-icing component 31 to move closer together, clamping the cable and working with the ice-breaking rods 312 to peel off the cable surface. The walking mechanism 1 can drive the entire device to move along the cable, and in conjunction with the reciprocating impact of the de-icing mechanism 3, it can achieve full and uniform de-icing of the cable, ensuring the safety and efficiency of the de-icing operation.

[0036] Clearly, the adjustment mechanism 2 drives the two clamping plates 311 belonging to different de-icing components 31, allowing the two clamping plates 311 to approach each other to clamp the cable and to move away from each other to release the cable. This allows for flexible control of the opening and closing of the clamping plates 311 via the adjustment mechanism 2. During hanging, the plates are fully open to avoid interference with the cable, and after hanging, they are closed to wrap around the cable. This also adapts to the clamping requirements of cables of different diameters, eliminating the need for dedicated devices for different cable specifications, improving the device's versatility, reducing operating costs, and ensuring strong clamping, thus guaranteeing the relative stability of the device and the cable during the de-icing process.

[0037] The ice-knocking rod 312 belonging to the same de-icing assembly 31 is slidably connected to the clamping plate 311, so that two ice-knocking rods 312 belonging to different de-icing assemblies 31 can move closer or further apart from each other; the ice-knocking rod 312 can reciprocate under the action of the driving source 313. This design can form a precise impact through the opposing movements of the ice-knocking rods 312 of different de-icing assemblies 31, which can efficiently peel off the ice covering the cable surface. Compared with traditional de-icing methods, the impact force is controllable, the de-icing is highly targeted, and damage to the cable body is avoided, thus balancing de-icing efficiency and cable protection.

[0038] Based on the fact that the walking mechanism 1 has a cable penetration cavity 11; the adjustment mechanism 2 is installed on the walking mechanism 1; and the de-icing mechanism 3 is installed on the walking mechanism 1, the coordination of each mechanism is enhanced. The walking mechanism 1 can drive the entire device to move smoothly along the cable. With the continuous operation of the de-icing mechanism 3, the cable can be de-iced evenly throughout its entire length. There is no need for manual climbing of the tower. It can be combined with deployment methods such as drone hoisting to greatly reduce the risk of high-altitude operations, improve the safety and coverage of de-icing operations, and reduce manpower input and operation time.

[0039] The drive source 313 can be an electric push rod, a pneumatic cylinder, a hydraulic motor, or a motor-driven screw rod.

[0040] refer to Figure 1 Preferably, the power tower de-icing device further includes a control system 4 and a vision detection module 5. The vision detection module 5 is installed on the walking mechanism 1 and is used to detect changes in the position of the cable passing through the penetration cavity. The control system 4 is electrically connected to the vision detection module 5, the de-icing mechanism 3, the walking mechanism 1, and the adjustment mechanism 2. With this configuration, the vision detection module 5 captures cable position shifts, swaying, and ice distribution in real time, and transmits the signals to the control system 4, which then synchronously controls the actions of each mechanism: if the cable position changes, the adjustment mechanism 2 promptly fine-tunes the opening and force of the clamping plate 311, the walking mechanism 1 corrects its movement trajectory, and the de-icing mechanism 3 adapts and adjusts the impact amplitude of the ice-beating rod 312, avoiding incomplete de-icing or the device detaching from the cable due to cable shift, significantly improving operational safety and stability. In this solution, the visual inspection module 5 can be flexibly selected. It is preferred to use a high-definition industrial camera with image recognition algorithm, which can intuitively capture the cable shape, ice thickness and position changes, and is suitable for complex outdoor lighting environments. Alternatively, a laser rangefinder sensor can be used to accurately locate the center position of the cable through laser reflection, with faster response speed and stronger resistance to rain, snow and fog interference, and is suitable for severe cold weather. An infrared thermal imaging module can also be selected, which can not only detect the position of the cable, but also distinguish the cable body from the ice-covered area, providing targeted operation signals for the de-icing mechanism 3, reducing invalid impacts and further improving de-icing efficiency.

[0041] refer to Figure 1 Preferably, the adjustment mechanism 2 includes an angle adjustment motor 21, a swing frame 22, and a tension / opening drive motor 23. The angle adjustment motor 21 is mounted on the walking mechanism 1, drives the swing frame 22, and causes the angle between the swing frame 22 and the horizontal plane to change. The tension / opening drive motor 23 is mounted on the swing frame 22 and drives two clamping plates 311 belonging to different de-icing components 31, so that the two clamping plates 311 can approach each other to clamp the cable and move away from each other to release the cable. This arrangement allows the adjustment function to be implemented in stages, greatly improving the functionality and adaptability of the adjustment mechanism 2. The opening and closing drive motor 23 is dedicated to controlling the opening and closing of the clamping plate 311, precisely controlling the clamping force and opening degree to ensure stable clamping of cables of different diameters, continuing the aforementioned versatility advantage. The angle adjustment motor 21 drives the swing frame 22 to adjust the overall angle of the de-icing mechanism 3, adapting to the tilted posture of the cable caused by the tower erection, ensuring that the ice-breaking rod 312 always maintains a reasonable impact angle with the cable surface. This setup also avoids the problem of insufficient adjustment precision caused by motion interference. The angle and opening / closing actions are independently controllable and work in concert, ensuring the stability of the de-icing mechanism 3 when fully open during drone hoisting, and dynamically adjusting according to the cable posture and diameter during de-icing operations, keeping the de-icing mechanism 3 in optimal working condition, further improving the thoroughness of de-icing and the cable protection effect. Among them, the angle adjustment motor 21 can be a servo motor or a stepper motor; the opening and closing drive motor 23 can be a planetary gear motor, a servo motor, or a brushless DC motor.

[0042] refer to Figure 1Preferably, the direction from the rear of the walking mechanism 1 to the front of the walking mechanism 1 is defined as the forward direction of the walking mechanism 1. The power tower de-icing device further includes a rotating support base 6, which has a supporting part 61 and a rotating part 62. The rotating part 62 is rotatably connected to the walking mechanism 1, so that the supporting part 61 is located in front of or behind the walking mechanism 1. The adjusting mechanism 2 is installed on the supporting part 61 to rotate with the supporting part 61. The rotating support base 6 can switch the front and rear positions of the adjusting mechanism 2 and the de-icing mechanism 3 through the rotating part 62, adapting to different cable installation scenarios and de-icing requirements. When the device needs to cross obstacles such as tower supports and cable joints, the support part 61 can be rotated to the rear of the traveling mechanism 1, driving the de-icing mechanism 3 to avoid the obstacles. The crossing can be completed without disassembling the device, significantly improving the continuity and efficiency of the operation. When the cable is locally covered with thick ice and requires intensive de-icing, the position of the support part 61 can be switched so that the de-icing mechanism 3 faces the iced area. With the coordinated action of the angle adjustment motor 21 and the opening and closing drive motor 23, targeted de-icing can be achieved. In this case, a rotating motor 65 can be installed in the rotating part 62, and a rotating shaft 12 can be installed in the traveling mechanism 1. The rotating shaft 12 is rotatably installed in the rotating part 62 and rotates under the drive of the rotating motor 65.

[0043] refer to Figure 1 Preferably, the rotating support 6 is connected to a counterweight 7. This arrangement improves the balance and stability of the device during high-altitude operations, compensating for the center of gravity shift caused by the rotating support 6 and its mounted adjustment mechanism 2 and de-icing mechanism 3. The counterweight 7 can balance the load on one side of the support part 61 with its own weight, ensuring even force distribution on both sides of the rotating support 6. This prevents the device from tilting or flipping along the cable due to excessive weight on one side, ensuring the stability of the drone during deployment and the smooth movement of the walking mechanism 1 along the cable during de-icing operations.

[0044] refer to Figure 1 and Figure 3 Preferably, the swing frame 22 is provided with an arc-shaped limiting groove 221, the center of which coincides with the swing center of the swing frame 22. The supporting part 61 of the rotating support 6 is provided with a limiting rod 63, which extends into the arc-shaped limiting groove 221. The limiting rod 63 is provided with a limiting key 64, which is used to prevent the limiting rod 63 from falling out of the arc-shaped limiting groove 221. The limiting rod 63 slides in conjunction with the arc-shaped limiting groove 221. The arc-shaped limiting groove 221 guides the limiting rod 63, ensuring that the swing frame 22 swings smoothly around a predetermined center and avoiding angle adjustment deviation. The limiting key 64 can firmly restrict the limiting rod 63, preventing them from separating due to vibration or impact during high-altitude operations and eliminating the risk of mechanism failure.

[0045] refer to Figure 1Preferably, the opening / closing drive motor 23 is mounted on the swing frame 22 via a telescopic drive device 24. The telescopic drive device 24 includes a telescopic drive rod 241 and a support plate 242. The telescopic drive rod 241 is mounted on the swing frame 22 and drives and supports the support plate 242. The opening / closing drive motor 23 is mounted on the support plate 242. The telescopic drive device 24 can drive the opening / closing drive motor 23 and the connected clamping plate 311 to make slight adjustments to their positions. This, combined with the opening / closing action, allows for the adaptation of cables with a wider range of diameters. Simultaneously, it can finely adjust the relative position of the clamping plate 311 and the cable, ensuring more precise clamping. This also compensates for positional deviations caused by swing angle adjustments, ensuring that the clamping plate 311 is always aligned with the center of the cable, improving clamping stability. The telescopic drive rod 241 can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod.

[0046] refer to Figure 1 Preferably, the support plate 242 is provided with a guide rod 243, which extends towards the swing frame 22 and is movably inserted through the swing frame 22. The guide rod 243 and the telescopic drive rod 241 form a bidirectional support, providing precise guidance for the telescopic movement of the support plate 242, preventing the support plate 242 from shifting or tilting when moving or under force, and ensuring the accurate movement trajectory of the opening and closing drive motor 23 and the clamping plate 311. At the same time, the guide rod 243 can share the lateral force generated by the de-icing impact, reduce the load on the telescopic drive rod 241, prevent it from deforming and being damaged due to uneven force, and extend the service life of the mechanism.

[0047] refer to Figure 2Preferably, the opening and closing drive motor 23 drives two clamping plates 311 belonging to different de-icing components 31 via a transmission assembly 8. The transmission assembly 8 includes a first drive shaft 81, a first drive gear 82, a second drive shaft 83, and a second drive gear 84. The first drive shaft 81 is connected to the opening and closing drive motor 23. The first drive gear 82 is sleeved on the first drive shaft 81. The first drive gear 82 and the second drive gear 84 are mutually geared and bonded, and the number of teeth of the first drive gear 82 is equal to the number of teeth of the second drive gear 84. The second drive gear 84 is sleeved on the second drive shaft 83. The first drive shaft 81 and the second drive shaft 83 are respectively mounted on the swing frame 22 via mounting brackets 85. The two clamping plates 311 belonging to different de-icing components 31 are respectively connected to swing rods 314. Each swing rod 314 is sleeved on one of the first drive shaft 81 and the second drive shaft 83 to rotate with it. The first drive gear 82 and the second drive gear, with equal teeth, mesh to achieve simultaneous rotation of the two drive shafts in opposite directions. This drives the connected swing rod 314 and the clamping plate 311 to move precisely in opposite directions, ensuring consistent opening and closing amplitudes of the clamping plate 311. Compared to direct drive, this structure offers higher transmission precision, preventing clamping plate 311 from shifting or damaging cables due to asynchronous movement. Furthermore, the gear transmission has strong load-bearing capacity, effectively mitigating the impact force of ice and ensuring stability during high-altitude operations.

[0048] refer to Figure 4 Preferably, the de-icing assembly 31 further includes a push-pull plate 315. Multiple ice-breaking rods 312 are provided, belonging to the same de-icing assembly 31. Each ice-breaking rod 312 is connected to the push-pull plate 315, and the push-pull plate 315 is driven by the drive source 313. The push-pull plate 315 enables a single drive source 313 to synchronously drive multiple ice-breaking rods 312, ensuring consistent movement of the rods and allowing simultaneous impact on multiple points of ice on the cable surface, significantly improving the de-icing coverage and operational efficiency. The push-pull plate 315 ensures uniform force distribution on the multiple ice-breaking rods 312, with synchronized and controllable impact force. This efficiently removes thick ice while avoiding excessive local impact that could damage the cable. Combined with the overall adjustment of the de-icing mechanism 3, it further enhances the adaptability to cables of different diameters and the stability of the de-icing process.
