Abstract

The present invention relates to the field of high-voltage transmission line maintenance, and in particular to a self-propelled de-icing device for transmission lines, comprising a plurality of de-icing components, a connecting component, and a driving component. The plurality of de-icing components are sequentially connected end to end through the connecting component to form a multilateral closed ring structure, and are simultaneously mounted on a plurality of high-voltage wires. The ice-breaking pendulum on each de-icing component rotates in the same direction under the control of the driving component to strike the ice. At this time, the ice-breaking pendulum is subjected to a reaction force equal to the striking force and opposite in direction. Due to the characteristics of the multilateral closed ring structure, the reaction forces generated by the ice-breaking pendulums of each de-icing component are radially symmetrically distributed, and their resultant force tends to zero, thereby effectively suppressing the shaking of the de-icing device during operation, achieving self-force balance, and significantly improving operational stability. In addition, a plurality of de-icing components can simultaneously perform de-icing operations on a plurality of high-voltage wires, greatly shortening the de-icing operation time.

Description

Technical Field

[0001] The present invention relates to the field of high-voltage power transmission line maintenance, and in particular to a self-propelled deicing device for power transmission lines. Background Art

[0002] A self-propelled de-icing device for power transmission lines is a device used to remove ice from transmission lines. It can move autonomously along the transmission lines and perform de-icing operations, effectively improving de-icing efficiency and ensuring a stable power supply. The device consists of a drive component, a de-icing component, a control and monitoring system, and an auxiliary support and protection component. The drive component enables the device to move autonomously along the high-voltage power lines. The de-icing component removes ice by mechanically breaking ice or heating to melt ice. The control and monitoring system implements intelligent control and status feedback, and the auxiliary components ensure safe operation. During operation, the device automatically moves along the high-voltage power lines after being deployed by the operator. Its sensors monitor the environment in real time, activating the de-icing component when ice is present and automatically adjusting when obstacles are encountered. After the operation is completed, the device shuts down and recycles, achieving efficient and safe de-icing of the transmission lines.

[0003] However, existing self-propelled de-icing devices typically only have a single drive assembly and de-icing component, designed to work with a single high-voltage power line. They are unable to achieve multi-line collaborative operation and require repeated disassembly and assembly to different lines. This significantly prolongs the overall de-icing process, misses the optimal de-icing opportunity, and results in excessive ice buildup, which can lead to line breakage, tripping, and other faults. Furthermore, when the de-icing device is de-icing, the de-icing component applies impact force to the single high-voltage power line, lacking stable support. This reaction force causes the device to shake violently, and in severe cases, it may even become unbalanced and detach from the high-voltage power line, causing the equipment to fall. Summary of the Invention

[0015] Furthermore, the connecting outer cylinder and the connecting inner cylinder can slide relative to each other, and a sliding plate is fixedly provided at one end of the connecting inner cylinder away from the second connecting rod, and the outer diameter of the sliding plate is larger than the outer diameter of the connecting inner cylinder and smaller than the inner diameter of the connecting outer cylinder. A sealing cylinder is detachably and coaxially fixed at one end of the connecting outer cylinder away from the first connecting rod, and the sealing cylinder is used to prevent the connecting inner cylinder from detaching from the connecting outer cylinder.

Based on the symmetry of the ring structure, the reaction forces cancel each other out, and the resultant force tends to zero, thereby effectively counteracting the shaking of the de-icing device during operation, achieving dynamic self-balancing, and significantly improving stability. At the same time, multiple de-icing components act synchronously on multiple high-voltage wires, greatly improving the de-icing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Refer to the following Figures 1 to 13 A self-propelled deicing device for a power transmission line provided by an embodiment of the present invention is described.

[0044] The self-propelled deicing device for a power transmission line includes a plurality of deicing assemblies 200 , a connecting assembly 300 and a driving assembly 400 .

[0045] The de-icing assembly 200 includes a mounting housing 210 and an ice-breaking pendulum 220. The mounting housing 210 serves as the mounting base for other components and is configured as a semi-enclosed frame structure. The lower portion of the mounting housing 210 is provided with an arc-shaped groove for placing the high-voltage wire 110. The width of the arc-shaped groove is adapted to the diameter of the high-voltage wire 110, allowing the high-voltage wire 110 to be embedded in the arc-shaped groove and positioned close to the center of the mounting housing 210 to ensure a stable center of gravity during de-icing operations. The ice-breaking pendulum 220 is rotatably connected to the outer peripheral wall of the mounting housing 210, and the length of the ice-breaking pendulum 220 covers the ice layer area on the surface of the high-voltage wire 110.

[0046] The connecting assembly 300 connects multiple de-icing assemblies 200 end-to-end, forming a multi-sided closed ring structure. The connecting assembly 300 can be composed of multiple adjustable connecting rods with multiple connection holes defined in the mounting housing 210. The ends of the adjustable connecting rods are inserted into the connection holes of the mounting housings 210 of adjacent de-icing assemblies 200 and secured with locknuts. A threaded adjustment sleeve is provided in the middle of the adjustable connecting rods, allowing the length of the adjustable connecting rods to be adjusted according to actual operational requirements. This allows multiple de-icing assemblies 200 to be connected end-to-end to form a multi-sided closed ring structure with varying side lengths.

[0047] The drive assembly 400 includes a first drive unit and a second drive unit. The first drive unit drives the ice-breaking pendulum 220 to rotate continuously in the same direction, using inertia to break the ice on the surface of the high-voltage wire 110; the second drive unit includes two first moving wheels 410, and the two first moving wheels 410 are rotatably connected to the inner circumferential wall of the mounting shell 210. The two first moving wheels 410 are arranged at intervals along the extension direction of the mounting shell 210. The two first moving wheels 410 are connected by a transmission structure and can achieve synchronous rotation, ensuring that the mounting shell 210 can move smoothly along the high-voltage wire 110.

[0048] Spacers 120 are typically installed along the multiple high-voltage wires 110, typically at intervals of tens to hundreds of meters. The specific spacing is determined based on the specifications of the high-voltage wires 110, the line voltage level, and weather conditions. Spacers 120 maintain a stable spacing between the multiple high-voltage wires 110, preventing them from colliding, abrading, or short-circuiting due to external forces such as wind vibration and swaying.

[0049] During operation, the device first assembles multiple de-icing assemblies 200 into a multi-sided closed ring structure using the connecting assembly 300. Each de-icing assembly 200 is then positioned over a high-voltage power line 110 near a spacer rod 120. Adjustable connecting rods are then adjusted to ensure that the first movable wheels 410 of each de-icing assembly 200 are in close contact with the respective high-voltage power line 110. After installation, the second and first drive units are activated, and the first movable wheels 410 begin to rotate, driving the multiple de-icing assemblies 200 forward at a constant speed along their respective high-voltage power lines 110. Simultaneously, the ice-breaking pendulum 220 strikes the ice covering the surface of the high-voltage power line 110 at a set frequency and force.

[0050] When the ice-breaking pendulum 220 strikes the ice, it experiences a reaction force equal in magnitude and opposite in direction. This force is transmitted to the entire de-icing system through the mounting housing 210. In a single-line de-icing system, this reaction force can cause noticeable shaking or even displacement of the system. In a multilateral closed-loop structure, however, the ice-breaking pendulum 220 of each de-icing assembly 200 strikes its corresponding high-voltage power line 110. When multiple de-icing assemblies 200 operate simultaneously, the reaction forces generated by each ice-breaking pendulum 220 striking the ice on the high-voltage power line 110 are distributed radially and symmetrically. Due to the symmetrical action of these reaction forces around the closed loop, they restrain each other in the circumferential direction, ultimately achieving a state of equilibrium.

[0051] Thus, configuring multiple de-icing assemblies 200 into a multi-sided closed ring structure effectively offsets the force generated by the ice-breaking pendulum 220 during the de-icing process, significantly improving the stability of the device's operation. Furthermore, multiple de-icing assemblies 200 can simultaneously de-ice multiple high-voltage power lines 110, significantly improving operational efficiency compared to traditional single-line de-icing methods.

[0052] Furthermore, the connection assembly 300 includes a first connector 310 and a second connector 320 , and the first connectors 310 and the second connectors 320 of adjacent de-icing assemblies 200 are connected. The first connector 310 and the second connector 320 together constitute the adjustable connecting rod proposed in the above embodiment.

[0053] Specifically, the mounting housing 210 is provided with two arcuate grooves 212 on the outer wall surfaces on both sides of the high-voltage wire 110 . The cross section of the arcuate groove 212 is semicircular, and its center coincides with the center position of the high-voltage wire 110 in the mounting housing 210 .

[0054] The first connector 310 includes a first connecting slide bar 311 , a first connecting rod 312 and a connecting outer cylinder 313 ; the second connector 320 includes a second connecting slide bar 321 , a second connecting rod 322 and a connecting inner cylinder 323 .

[0055] The ends of the first connecting slide 311 and the second connecting slide 321 are respectively tightly snapped into the two arcuate grooves 212 on one side of the mounting housing 210. The first connecting slide 311 and the second connecting slide 321 can freely rotate within the arcuate groove 212 with the high-voltage wire 110 as the axis. The first connecting rod 312 is vertically fixedly connected to the first connecting slide 311, and the second connecting rod 322 is vertically fixedly connected to the second connecting slide 321. The first connecting rod 312 and the second connecting rod 322 are coaxially connected. When the angle between adjacent deicing assemblies 200 changes due to bending of the high-voltage wire 110 or changes in spacing, the first connecting slide 311, the second connecting slide 321, the first connecting rod 312, the second connecting rod 322, and the arcuate groove 212 enable relative deflection between the deicing assemblies 200.

[0056] First connecting rod 312 is coaxially and detachably fixed with a connecting outer cylinder 313 by a first bolt. Connecting outer cylinder 313 extends toward second connecting rod 322, and the position of connecting outer cylinder 313 on first connecting rod 312 is adjustable. Second connecting rod 322 is coaxially and detachably fixed with a connecting inner cylinder 323 by a second bolt. Connecting inner cylinder 323 extends toward first connecting rod 312, and the position of connecting inner cylinder 323 on second connecting rod 322 is adjustable. Connecting outer cylinder 313 is coaxially sleeved on connecting inner cylinder 323, and connecting outer cylinder 313 and connecting inner cylinder 323 are adapted to accommodate de-icing assemblies 200 with different spacings. Connecting outer cylinder 313 and connecting inner cylinder 323 are fixed by a third bolt to prevent relative displacement of connecting outer cylinder 313 and connecting inner cylinder 323 during operation of the device.

[0057] Before placing the device on the high-voltage wires 110, the operator first loosens the first and second bolts based on the spacing between the multiple high-voltage wires 110 to be deiced. This allows the outer connecting cylinder 313 and the inner connecting cylinder 323 to slide axially on the first and second connecting rods 312 and 322 to a predetermined position, and then tightens the first and second bolts. The outer connecting cylinders 313 on multiple deicing assemblies 200 are sequentially placed over the inner connecting cylinders 323 on adjacent deicing assemblies 200, and the outer and inner connecting cylinders 313 and 323 are pre-tightened using the third bolt. At this point, the spacing between the multiple deicing assemblies 200 corresponds to the spacing between the multiple high-voltage wires 110 to be deiced.

[0058] After the operator places the device on multiple high-voltage wires 110, he tightens the third bolt so that the connecting outer cylinder 313 and the connecting inner cylinder 323 are fixedly connected and no longer slide relative to each other; after the installation is completed, the first drive unit and the second drive unit are started to drive the multiple deicing assemblies 200 to de-ice the multiple high-voltage wires 110.

[0059] When it is necessary to further adjust the spacing between adjacent de-icing assemblies 200, the operator can use the first bolt and the second bolt to adjust the positions of the connecting outer cylinder 313 and the connecting inner cylinder 323 along the first connecting rod 312 and the second connecting rod 322 respectively, and re-fix them to change the distance between the de-icing assemblies 200 to adapt to multiple high-voltage wires 110 of different specifications or operational requirements.

[0060] In one embodiment, in order to further improve the stability of the device during operation, a first elastic member 315 and a second elastic member 325 are provided between the connecting outer cylinder 313 and the connecting inner cylinder 323 .

[0061] Specifically, a sliding plate 324 is fixedly provided at the end of the connecting inner cylinder 323 away from the second connecting rod 322. The outer diameter of the sliding plate 324 is larger than the outer diameter of the connecting inner cylinder 323 and smaller than the inner diameter of the connecting outer cylinder 313. A blocking cylinder 314 is detachably and coaxially fixedly provided at the end of the connecting outer cylinder 313 away from the first connecting rod 312. The blocking cylinder 314 has a through hole at its center that matches the connecting inner cylinder 323. The connecting inner cylinder 323 passes through the through hole of the blocking cylinder 314 and can slide relative to it. The blocking cylinder 314 is used to prevent the connecting inner cylinder 323 from being separated from the connecting outer cylinder 313. Therefore, the third bolt in the above embodiment no longer securely connects the outer cylinder 313 and the connecting inner cylinder 323. Instead, the outer cylinder 313 and the blocking cylinder 314 are securely connected by the third bolt.

[0062] One end of the first elastic member 315 abuts against the upper wall of the connecting outer tube 313, and the other end of the first elastic member 315 abuts against the upper wall of the sliding plate 324. One end of the second elastic member 325 abuts against the blocking tube 314, and the other end of the second elastic member 325 abuts against the lower wall of the sliding plate 324. The combined elastic force of the first elastic member 315 and the second elastic member 325 always forces the sliding plate 324 toward the center of the connection between the outer tube 313 and the blocking tube 314.

[0063] When the operator adjusts the connecting outer cylinder 313 and the connecting inner cylinder 323 to the preset position, the sliding plate 324 is located at the center of the connecting outer cylinder 313 and the blocking cylinder 314 under the action of the first elastic member 315 and the second elastic member 325. The operator then pre-tightens the connecting outer cylinder 313 and the blocking cylinder 314 using the third bolt. After the operator places the device on multiple high-voltage wires 110, the operator tightens the third bolt to securely connect the connecting outer cylinder 313 and the blocking cylinder 314, while allowing the connecting inner cylinder 323 to slide relative to the connecting outer cylinder 313.

[0064] During operation of the device, when adjacent deicing assemblies 200 are stretched or squeezed by external force, the connecting inner cylinder 323 slides in the connecting outer cylinder 313 , driving the sliding plate 324 to squeeze the first elastic member 315 or the second elastic member 325 .

[0065] When the distance between adjacent de-icing assemblies 200 is increased due to external force, the sliding plate 324 moves downward to compress the second elastic member 325, and the reverse elastic force generated by the second elastic member 325 causes the sliding plate 324 to have an upward trend; similarly, when the distance between adjacent de-icing assemblies 200 is reduced due to squeezing, the sliding plate 324 moves upward to compress the first elastic member 315, and the reverse elastic force generated by the pressure on the first elastic member 315 causes the sliding plate 324 to have a downward trend.

[0066] The buffering effect of first and second elastic members 315, 325 effectively absorbs the impact force generated by the vibration of high-voltage power lines 110 or the operation of ice-breaking pendulum 220, preventing structural damage caused by rigid collisions. Furthermore, first and second elastic members 315, 325 effectively offset displacement deviations of the multiple de-icing assemblies 200 caused by external forces, ensuring that the de-icing assemblies 200 maintain a stable spacing.

[0067] In one embodiment, in order to improve the stability of the high-voltage wire 110 and the de-icing assembly 200 during the de-icing operation and prevent the high-voltage wire 110 from being separated from the de-icing assembly 200 due to external force, the de-icing assembly 200 further includes a mounting plate 211 and a limiting annular rod 240. The mounting plate 211 is vertically fixed to the middle of the inner wall of the mounting shell 210, parallel to the upper wall surface of the mounting shell 210 and maintained at a distance. The limiting annular rod 240 is rotatably connected to the mounting plate 211. The limiting annular rod 240 is located between the two first movable wheels 410. The limiting annular rod 240 can rotate in a direction parallel to the axis of the high-voltage wire 110. The inner diameter of the limiting annular rod 240 contacts the high-voltage wire 110. The first movable wheels 410 and the limiting annular rod 240 jointly clamp the high-voltage wire 110 to limit the radial displacement of the high-voltage wire 110. During the operation of the device, when the de-icing device moves along the high-voltage wire 110, the first moving wheel 410 drives the device forward through the friction with the surface of the high-voltage wire 110, and the limiting ring rod 240 continuously restrains the radial shaking of the high-voltage wire 110 to prevent the high-voltage wire 110 from detaching, thereby improving the reliability and operational safety of the de-icing device.

[0068] Furthermore, the de-icing assembly 200 further includes a first hydraulic cylinder 316 , a first piston rod 326 , a second hydraulic cylinder 250 , a second piston rod 260 , a drive rack 270 and a second gear 271 .

[0069] First hydraulic cylinder 316 is fixedly connected to first connecting rod 312, and first piston rod 326 is fixedly connected to second connecting rod 322. First piston rod 326 is coaxially slidably connected to first hydraulic cylinder 316. First hydraulic cylinder 316 and first piston rod 326 are used to transmit the spacing change between adjacent de-icing assemblies 200.

[0070] The second hydraulic cylinder 250 is fixedly mounted on the mounting housing 210, and the second piston rod 260 is coaxially slidably connected within the second hydraulic cylinder 250. The first hydraulic cylinder 316 and the second hydraulic cylinder 250 are connected via a fluid delivery tube 317, forming a closed hydraulic circuit. When the first piston rod 326 slides within the first hydraulic cylinder 316, hydraulic oil, through the fluid delivery tube 317, pushes the second piston rod 260 to move synchronously.

[0071] One end of the driving rack 270 is fixedly connected to the second piston rod 260. A sliding groove 272 is provided on the side of the driving rack 270. A limiting slider 213 is provided on the mounting plate 211. The limiting slider 213 is embedded in the sliding groove 272 to form a sliding pair, which limits the driving rack 270 to move only in a direction perpendicular to the high-voltage wire 110.

[0072] A short rod 241 extends coaxially from the central axis of the limiting annular rod 240 and is fixedly connected to the limiting annular rod 240. A first gear 242 is fixedly mounted on the short rod 241, and the first gear 242 rotates synchronously with the limiting annular rod 240. A second gear 271 is fixedly mounted on the mounting plate 211 and meshes with both the first gear 242 and the drive rack 270.

[0073] Before the device is operated, the operator adjusts the connecting outer cylinder 313 and the connecting inner cylinder 323 to the initial preset positions so that the sliding plate 324 is located at the center position inside the connecting outer cylinder 313 and the blocking cylinder 314 .

[0074] During the operation of the device, when the connecting outer cylinder 313 and the connecting inner cylinder 323 of the adjacent de-icing components 200 are close to each other due to the bending of the line or the extrusion of external force, the connecting outer cylinder 313 and the connecting inner cylinder 323 squeeze the first elastic member 315, and at the same time, the first piston rod 326 retracts into the first hydraulic cylinder 316; the hydraulic oil pushes the second piston rod 260 to extend and move upward in the second hydraulic cylinder 250 through the infusion pipe 317, driving the driving rack 270 to move upward perpendicular to the direction of the high-voltage wire 110; the driving rack 270 drives the second gear 271 to rotate through the gear transmission, thereby driving the first gear 242 and the limiting ring rod 240 to rotate forward, so that the limiting ring rod 2 40 further tightens the constraint on the high-voltage wire 110, realizing dynamic adaptive clamping of the high-voltage wire 110; conversely, when the de-icing assembly 200 needs to pass over the spacer rod 120, the multiple first moving wheels 410 push the spacing between adjacent de-icing assemblies 200 to increase, and the connecting outer cylinder 313 and the connecting inner cylinder 323 squeeze the second elastic member 325, and the connecting outer cylinder 313 and the connecting inner cylinder 323 move away from each other; at this time, the first piston rod 326 extends from the first hydraulic cylinder 316, and the hydraulic oil reflux pushes the second piston rod 260 to retract, driving the rack 270 to move downward, driving the limiting annular rod 240 to rotate in the opposite direction, loosening the clamping of the high-voltage wire 110, and facilitating the de-icing assembly 200 to pass over the spacer rod 120.

[0075] Therefore, the distance change between adjacent de-icing components 200 is converted into the linear motion of the second piston rod 260 through a closed hydraulic circuit, and the linear motion of the second piston rod 260 is converted into the rotational motion of the limiting ring rod 240 through gear transmission, thereby realizing dynamic constraint control of the high-voltage wire 110 and ensuring the stability and reliability of the device operation.

[0076] Furthermore, during operation, when the de-icing device reaches the spacer rod 120, if driven solely by the first moving wheel 410, it is possible that the first moving wheel 410 has already passed the spacer rod 120, but the limiting ring rod 240 remains on one side of the spacer rod 120 due to delayed spacing adjustment or the influence of ice, causing the de-icing device to become stuck or even damage the power transmission line. For this reason, the de-icing assembly 200 also includes a second moving wheel 420.

[0077] Specifically, the second moving wheel 420 is rotatably mounted within the mounting housing 210, positioned between the limiting annular rod 240 and the first moving wheel 410. The second moving wheel 420 and the first moving wheel 410 are connected by a transmission structure. When the first moving wheel 410 rolls along the high-voltage power line 110, the transmission structure drives the second moving wheel 420 to rotate synchronously.

[0078] During the movement of the de-icing device, the first moving wheel 410 and the second moving wheel 420 roll synchronously, jointly supporting and pushing the de-icing device forward; when the first moving wheel 410 contacts and passes over the spacer bar 120, the second moving wheel 420 still maintains effective contact with the high-voltage wire 110, continuously providing driving force, and ensuring that the limiting ring rod 240 can smoothly follow and pass through the spacer bar 120.

[0079] Through the transition support and power transmission of the second moving wheel 420 at the spacer rod 120, the deicing device can pass through the complex line structure more smoothly and efficiently, effectively reducing the frequency of shutdown and maintenance caused by jamming, and improving the overall deicing operation efficiency.

[0080] In one embodiment, the first driving unit includes a first motor 430 , and the second driving unit includes a second motor 440 . The first motor 430 and the second motor 440 are fixedly installed in the mounting housing 210 .

[0081] During the startup phase of the de-icing device, the operator first starts the second motor 440 to drive the first moving wheel 410 to roll along the high-voltage wire 110, driving the entire de-icing device to move forward smoothly; when the device enters the ice-covered area, the de-icing device enters the de-icing phase, and then starts the first motor 430 to drive the ice-breaking pendulum 220 to start hitting the ice on the high-voltage wire 110 to de-ice.

[0082] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
