[0001] This disclosure relates to the field of power maintenance technology, and in particular to a snow removal and de-icing device for power transmission lines. Background Technology

[0002] With the accelerating pace of global climate change, extreme weather events are becoming more frequent, with particularly severe winters posing unprecedented challenges to the stable operation of power systems. Among these challenges, icing of transmission lines is especially prominent, becoming a key factor restricting the reliability of power systems. Icing disasters on transmission lines not only lead to a sharp deterioration in the mechanical and electrical performance of the lines, but also trigger a series of chain reactions, such as line overload, severe icing of insulator strings, and violent galloping of transmission lines. These events pose a serious threat to the safe operation of the power system and cause incalculable economic losses and social impacts.

[0003] Faced with this severe situation, there are currently three de-icing methods: manual de-icing, mechanical de-icing, and thermal de-icing. However, all three methods have significant technical drawbacks: manual de-icing is limited by labor costs and operational efficiency, making it difficult to deploy quickly in situations of large-scale icing, and it also carries high safety risks; mechanical de-icing has limited applicability, is greatly constrained by terrain and environmental conditions, and improper operation can easily damage transmission lines, affecting their service life; thermal de-icing requires a large amount of energy, increasing the operating costs of the power system. Summary of the Invention

[0004] The purpose of this invention is to provide a snow removal and de-icing device for power transmission lines, which has high de-icing efficiency, does not require a large amount of energy consumption, and has a wide range of applications.

[0005] To achieve this objective, the present invention adopts the following technical solution: A snow removal and de-icing device for power transmission lines includes a de-icing device and a traction device. The de-icing device includes a receiving seat disposed at the movable end of the traction device. The inner cavity of the receiving seat is provided with a partition plate, which is used to divide the inner cavity into two chambers. Each chamber is equipped with a clamping unit. The clamping unit includes a screw, a first driving member, a guide block, and a clamping seat. The screw is rotatably mounted in the chamber. The first driving member is mounted in the chamber and is used to drive the screw to rotate. The guide block is screwed to the screw and slides along the length direction of the receiving seat. The bottom of the guide block extends out of the receiving seat and connects to the clamping seat.

[0006] Preferably, the clamping base includes an assembly frame and a clamping plate. The assembly frame is n-shaped, with the openings of the two assembly frames facing each other. The top of the assembly frame is connected to the guide block. The clamping plate is disposed at the opening of the assembly frame, and the opposite side of the two clamping plates is the arc-shaped surface.

[0007] Preferably, the clamping unit further includes several return springs, each with an integrated damper. One end of each return spring is connected at intervals to the inner wall of the assembly frame, and the other end of each return spring is connected to the clamping plate.

A traction device allows a receiving seat to move freely, precisely positioning it at the designated location requiring snow and ice removal. Two first driving components are activated, driving two screws to rotate. A guide block moves along the screw axis, causing two clamping seats to approach each other, forming a circular clamping structure that tightly and stably adheres to the power transmission line.

This invention is not limited by terrain or environmental conditions. Combining mechanical de-icing with thermal melting, it significantly improves de-icing efficiency without consuming large amounts of energy, ensuring the safety and stability of power transmission.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0019] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0022] Icing disasters on power transmission lines not only cause a sharp deterioration in the mechanical and electrical performance of the lines, but also trigger a series of chain reactions such as line overload, severe icing of insulator strings, and violent galloping of transmission lines, posing a serious threat to the safe operation of the power system. However, the three commonly used de-icing methods—manual de-icing, mechanical de-icing, and thermal de-icing—all have significant technical drawbacks: manual de-icing is limited by labor costs and operational efficiency, making it difficult to deploy quickly in situations of large-scale icing, and it also carries high safety risks; mechanical de-icing has a limited scope of application, is greatly constrained by terrain and environmental conditions, and improper operation can easily damage transmission lines, affecting their service life; thermal de-icing requires a large amount of energy, increasing the operating costs of the power system.

[0023] Therefore, this embodiment provides a snow removal and de-icing device for power transmission lines, which has high de-icing efficiency, does not consume a lot of energy, and has a wide range of applications.

[0024] Please see Figures 1 to 6 The snow removal and de-icing device for power transmission lines provided in this embodiment includes a traction device 2 and a de-icing device 1. The de-icing device 1 is located at the moving end of the traction device 2. The traction device 2 can drive the de-icing device 1 to move freely to assist the de-icing device 1 in de-icing the power transmission line. The traction device 2 can move freely and can also flexibly adjust its height. It has a wide range of applications and is not restricted by terrain, environment or other conditions.

[0025] The de-icing device 1 provided in this embodiment combines mechanical de-icing and thermal melting mechanisms, which can quickly and thoroughly remove ice and snow from power transmission lines. It has high de-icing efficiency and does not require a large amount of energy consumption.

[0026] Specifically, please refer to Figure 1 , Figure 2 and Figure 4 The de-icing device 1 includes a receiving seat 11. The top of the receiving seat 11 is connected to the moving end of the traction device 2. The inner cavity of the receiving seat 11 is provided with a partition plate 12 in the middle area, which divides the inner cavity into two independent cavities. Preferably, the two cavities are spaced apart along the length of the receiving seat 11. At the same time, a clamping unit is installed inside each cavity. The two clamping units are close to each other to clamp the power transmission line, and the two clamping units are far apart to release the power transmission line.

[0027] Further, please refer to Figure 1 , Figure 2 and Figure 4 The clamping unit includes a screw 13, a first driving member 14, a guide block 15, and a clamping seat 16. The screw 13 is rotatably mounted in the cavity. Preferably, the screw 13 is arranged along the length direction of the receiving seat 11. The first driving member 14 is mounted in the cavity, and the output end of the first driving member 14 is fixedly connected to the end of the screw 13 for driving the screw 13 to rotate. The guide block 15 is screwed to the screw 13 and is slidably arranged in the corresponding cavity along the length direction of the receiving seat 11. The bottom of the guide block 15 extends out of the receiving seat 11, and the bottom of the guide block 15 is connected to the clamping seat 16. Furthermore, the opposite sides of the two clamping seats 16 are both arc-shaped surfaces, and the two arc-shaped surfaces can cooperate to form a circular clamping structure. In this embodiment, several toothed blocks 17 are spaced apart on the arc-shaped surfaces, and heating elements 18 are also provided on the arc-shaped surfaces.

[0028] Preferably, please refer to Figure 5Two guide grooves 111 are provided at intervals along the length of the bottom of the receiving seat 11. The guide grooves 111 are connected to the inner cavity of the receiving seat 11 and are both provided along the length of the receiving seat 11. The bottoms of the two guide blocks 15 extend out of the two guide grooves 111 respectively. By providing the guide grooves 111, the guide blocks 15 are guided to slide along the length of the receiving seat 11.

[0029] With the above setup, the traction device 2 drives the receiving seat 11 to move along the power transmission line, precisely bringing the receiving seat 11 to the designated location where snow and ice removal is required. Once the receiving seat 11 reaches the designated location, the first driving component 14 is activated. The power of the first driving component 14 is efficiently transmitted to the two screws 13, driving them to rotate. Under the action of the screws 13, the guide block 15 moves along the axial direction of the screws 13, while simultaneously maintaining a sliding fit with the corresponding cavity, providing precise guidance. As the guide block 15 moves, it drives the clamping seat 16 to move together. 6. The components move close together to form a circular clamping structure, which fits tightly and stably onto the power line. This structure is adaptable to power lines of different diameters, improving the flexibility and adaptability of de-icing operations. The toothed blocks 17 act directly on the ice and snow, and the heating element 18 generates heat quickly when energized. The heat acts on the ice and snow attached to the power line. The traction device 2 drives the receiving seat 11 to move forward gradually along the power line. The toothed blocks 17 physically break down the ice and snow, and the heating element 18 uses heat to melt the remaining ice and snow, ensuring that the ice and snow are completely removed. Finally, the ice and snow on the entire power line are gradually and thoroughly removed.

[0030] This embodiment combines mechanical de-icing and thermal de-icing mechanisms to quickly and thoroughly remove ice and snow from power transmission lines, greatly improving de-icing efficiency without consuming a large amount of energy, thus ensuring the safety and stability of power transmission.

[0031] For example, please refer to Figure 6 The clamping base 16 includes an assembly frame 161 and a clamping plate 162. The assembly frame 161 is n-shaped, with the openings of the two assembly frames 161 facing each other. The bottom of the guide block 15 is connected to the top of the assembly frame 161. The clamping plate 162 is disposed at the opening of the assembly frame 161 and is arc-shaped, so that the opposite sides of the two clamping plates 162 are both the aforementioned arc-shaped surfaces.

[0032] Preferably, the heating element 18 is designed to conform to the curvature of the arc surface and is embedded inside the clamping plate 162.

[0033] Preferably, in this embodiment, a temperature sensor 1a is installed on the inner wall of the assembly frame 161. The temperature sensor 1a is electrically connected to the heating element 18. The temperature sensor 1a is used to monitor the temperature of the assembly frame 161, the clamping plate 162 and its surrounding environment in real time and accurately, so as to ensure that the heating element 18 is within a suitable temperature range, accurately control the working state of the heating element 18, and prevent overheating.

[0034] Furthermore, the clamping unit provided in this embodiment also includes several return springs 19, each of which integrates a damper. One end of each return spring 19 is connected at intervals to the inner wall of the assembly frame 161, and the other end of each return spring 19 is connected to the clamping plate 162. During the de-icing process, the toothed block 17 acts directly on the ice and snow, and the two clamping plates 162 are subjected to the reaction force from the ice and snow on the transmission line. The combination of the return springs 19 and the dampers can absorb and buffer these reaction forces, ensuring the stability of the two clamping plates 162, while avoiding unnecessary damage to the transmission line and protecting the integrity and safety of the transmission line.

[0035] The de-icing device 1 provided in this embodiment also has a cleaning function. For example, please refer to... Figure 1 and Figure 2 Two horizontal plates 1b are spaced apart along the width direction at the bottom of the receiving seat 11. The horizontal plates 1b are arranged along the length direction of the receiving seat 11. The clamping seat 16 is located between the two horizontal plates 1b, and a broom 1c is arranged along the length direction at the bottom of the horizontal plates 1b.

[0036] With the above setup, as the de-icing device 1 moves along the power transmission line, one of the brooms 1c first comes into contact with the ice and snow on the power transmission line, and its soft bristles easily sweep away the floating snow and loose ice crystals on the surface. After the de-icing process is completed, the other broom 1c performs a second cleaning of the power transmission line to ensure that the surface of the power transmission line is clean and free of residue, providing a safe and reliable guarantee for subsequent power transmission.

[0037] Please see Figures 1 to 3 The traction device 2 provided in this embodiment includes a drone 21, a connecting block 22, and a traction frame 23. The connecting block 22 is connected to the bottom of the drone 21, and the traction frame 23 is connected to the side of the connecting block 22 away from the drone 21. Two vertical plates 24 are symmetrically arranged on the traction frame 23, and a roller 25 is installed between the two vertical plates 24. A steel wire rope 26 is wound on the roller 25, and the end of the steel wire rope 26 is connected to a receiving seat 11. When the drone 21 is started to fly, it drives the connecting block 22 and the traction frame 23 to move synchronously. The strong traction force of the steel wire rope 26 pulls the receiving seat 11 to the designated position where snow and ice need to be cleared, thereby achieving the traction purpose.

[0038] Optionally, please refer to Figures 1 to 4A locking buckle 261 is provided at the end of the wire rope 26, and a connecting ring 112 is provided at the top of the receiving seat 11. The locking buckle 261 can be locked to the connecting ring 112 to form a stable connection between the wire rope 26 and the receiving seat 11.

[0039] In some feasible embodiments, please refer to Figure 7 The vertical plate 24 is set on the top of the traction frame 23 to strengthen the support of the traction frame 23 for the vertical plate 24. Accordingly, a through hole 231 is opened in the middle area of ​​the traction frame 23, and the end of the wire rope 26 extends into the through hole 231 to achieve connection with the receiving seat 11.

[0040] In this embodiment, the roller shaft 25 is rotatably mounted between two vertical plates 24. Specifically, the rotation of the roller shaft 25 is limited to the two vertical plates 24. A second driving member 27 is provided on the outer side of one of the vertical plates 24. The output end of the second driving member 27 is connected to the end of the roller shaft 25. The second driving member 27 drives the roller shaft 25 to rotate to release or retract the wire rope 26.

[0041] For other feasible embodiments, please refer to Figure 2 Alternatively, a protective cover 232 can be installed on the top of the traction frame 23 to cover the roller 25, the second drive component 27 and the two vertical plates 24, so that the protective cover 232 can protect them.

[0042] With the above settings, when the receiving seat 11 reaches the designated position, the second driving component 27 drives the roller 25 to rotate clockwise, releasing the wire rope 26 to increase the distance between the receiving seat 11 and the drone 21. Alternatively, the second driving component 27 drives the roller 25 to rotate counterclockwise, retracting the wire rope 26 to shorten the distance between the receiving seat 11 and the drone 21. This allows for flexible adjustment of the traction height to meet different operational needs, further expanding the scope of application and making it unrestricted by terrain, environment, or other conditions.

[0043] Furthermore, two electric push rods 28 are symmetrically arranged at the bottom of the traction frame 23. The telescopic ends of the electric push rods 28 are equipped with assembly frames 29. The limiting rollers 2a are rotatably installed between the two assembly frames 29. After the end of the wire rope 26 extends into the through hole 231 and is connected to the receiving seat 11, the wire rope 26 remains between the two limiting rollers 2a.

[0044] By setting two limiting rollers 2a, the swing arc of the wire rope 26 during the traction process is limited, ensuring that it moves within the predetermined path, thereby improving the reliability and safety of traction. Furthermore, by controlling the extension or retraction of the electric push rod 28, the two limiting rollers 2a on the assembly frame 29 are raised or lowered, thereby achieving the adjustment of the limiting height.

[0045] Optionally, please refer to Figure 7A limiting groove 2a1 is opened in the middle area of ​​the limiting roller 2a along its circumference. The groove wall of the limiting groove 2a1 is a smooth arc shape, which reduces the resistance and wear of the wire rope 26 due to contact with the limiting roller 2a.

[0046] The working process of the snow removal and de-icing device for power transmission lines provided in this embodiment is as follows: First, start the drone 21, which drives the connecting block 22 and the traction frame 23 to move synchronously. The steel wire rope 26 pulls the receiving seat 11 to the designated position where snow and ice need to be cleared. The second driving component 27 drives the roller shaft 25 to rotate clockwise or counterclockwise, releasing or retracting the steel wire rope 26 to increase or shorten the distance between the receiving seat 11 and the drone 21. The traction height is flexibly adjusted. The electric push rod 28 is extended or shortened according to the actual conditions, and the limit height of the two limit rollers 2a is adjusted to ensure that the swing of the steel wire rope 26 during the traction process is always between the two limit rollers 2a. When the receiving seat 11 reaches the designated position, the two first driving components 14 are activated, driving the two screws 13 to rotate. The guide block 15 moves along the axis of the screw 13. As the guide block 15 moves, the clamping seat 16 moves together. The two clamping seats 16 approach each other and together form a circular clamping structure, which fits tightly and stably on the power transmission line. The drone 21 drives the receiving seat 11 to move forward along the power line. One of the brooms 1c first comes into contact with the ice and snow on the power line. Its soft bristles easily sweep away the surface snow and loose ice crystals. The toothed block 17 physically breaks down the ice and snow. The heating element 18 uses heat to melt the remaining ice and snow, ensuring that the ice and snow are completely removed. The other broom 1c performs a second cleaning of the power line to ensure that the surface of the power line is clean and free of residue. Finally, the ice and snow on the entire power line are gradually and thoroughly removed.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
