Description

Technical Field

[0001] This invention belongs to the field of power equipment maintenance technology, specifically relating to a vibration de-icing device for power transmission lines. Background Technology

[0002] In power systems, icing of transmission lines is a common natural disaster that poses a serious threat to the safety and stability of power transmission. In the low temperatures of winter, ice will freeze on the surface of transmission lines. As the thickness of the ice gradually increases, the load on the lines will increase significantly. This may not only cause towers to tilt and collapse, but also cause line breakage accidents due to excessive stretching of conductors. In severe cases, it may even cause large-scale power outages, which will have a great impact on industrial production and residents' lives.

[0003] In existing de-icing devices for power transmission lines, tracked de-icing machines are commonly used. These machines remove ice by rolling and crushing the ice layer through contact between the tracks and the line surface. However, this single mechanical crushing method has significant limitations. The de-icing effect is not ideal, as the crushing force of the tracks alone is insufficient to completely remove the ice layer. This is especially true for thick ice layers or hard mixed ice formed in low-temperature environments. The crushing force of the tracks often only breaks the surface ice shell, while the deeper ice layer remains attached to the conductor surface, failing to achieve efficient de-icing. This results in the possibility of re-icing shortly after de-icing, increasing the cost of repeated operations. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration de-icing device for power transmission lines to solve the problem of unsatisfactory de-icing effect mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vibration de-icing device for power transmission lines, comprising a first support frame, wherein the first support frame is provided with a track walking assembly, a vibration de-icing mechanism and a clamping and limiting mechanism; The tracked walking assembly is used to adjust the working position of the power transmission line, and when the tracked walking assembly moves, it is used to crush and break the ice layer. The vibration de-icing mechanism is used for resonant de-icing; The clamping and limiting mechanism is used to clamp the power transmission line; The tracked walking assembly is installed in the first working area of ​​the first support frame, while the vibration de-icing mechanism and the clamping and limiting mechanism are located in the second working area of ​​the first support frame, with the vibration de-icing mechanism located above the clamping and limiting mechanism.

[0006] In a preferred embodiment, the tracked walking assembly comprises a track, a drive shaft, a driven shaft, a bearing housing, and a drive motor. The drive shaft and the driven shaft are mounted on the first support frame in conjunction with the bearing housing, and the output end of the drive motor is connected to the drive shaft for transmission.

[0007] In a preferred embodiment, a clamping plate is provided on one side of the bearing housing, and the bearing housing is mounted on the crossbeam of the first support frame in conjunction with the clamping plate.

[0008] In a preferred embodiment, the track surface is provided with friction protrusions.

[0009] In a preferred embodiment, the vibration de-icing mechanism includes a mounting frame, which is bolted to a first support frame. The mounting frame is equipped with a transmission frame and a vibration motor, which is mounted on the transmission frame.

[0010] In a preferred embodiment, a transfer plate is bolted to the bottom of the transfer frame, and the clamping and limiting mechanism is located on the transfer plate.

[0011] In a preferred embodiment, the clamping and limiting mechanism mainly consists of a movable arm, a U-shaped clamping frame, a clamping roller, and an adjusting plate. The movable arm is hinged to the two side walls of the transfer plate, and the adjusting plate is hinged to the movable arm in conjunction with the connecting rod.

[0012] In a preferred embodiment, the clamping roller array is disposed in a U-shaped clamping frame, the U-shaped clamping frame is fitted with bolts on one side of the two movable arms, and at the lower end of the adjusting plate located above the middle of the two movable arms.

[0013] In a preferred embodiment, a telescopic rod is installed at the lower end of the transfer plate, and the telescopic rod is bolted to the lower end of the transfer plate. An adapter block is provided at the output end of the telescopic rod, and the adapter block is bolted to the middle position of the adjusting plate. In a preferred embodiment, the first support frame has two symmetrical sets, and the two sets of the first support frame are hinged to the two sets of second support frames by means of hinge blocks. Each set of the second support frames is equipped with a power supply battery.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This transmission line uses a vibration de-icing device that combines the crushing and crushing action of the tracked walking assembly with the resonant de-icing action of the vibrating de-icing mechanism. The tracked walking assembly uses surface friction protrusions to initially crush the ice layer on the outside of the transmission line, which can quickly break the surface ice shell and create conditions for vibration transmission, laying the foundation for subsequent deep de-icing. The vibrating de-icing mechanism uses the high-frequency resonant energy generated by the vibration motor to reach the inside of the ice layer along the transmission frame and clamping mechanism, causing deep and hard ice layers to crack due to resonant force and completely disintegrate and fall off. Especially for thicker ice or hard mixed ice that has frozen at low temperatures, compared with traditional devices that only rely on tracked crushing, it can achieve complete removal of ice from the surface to the inside, greatly improving de-icing efficiency, reducing repeated work caused by incomplete de-icing, and reducing equipment wear and labor costs. The vibration de-icing device for the transmission line has two symmetrical sets on the first support frame and is hinged to the second support frame through a hinge block, which makes it easy to adjust the shape of the device according to the actual situation. The telescopic rod can adjust the clamping state of the clamping limit mechanism so that it can adapt to transmission lines of different diameters. This transmission line vibration de-icing device features two sets of power batteries, each mounted on a second support frame on either side. This design not only provides stable and continuous power support for all components, ensuring the continuous and efficient operation of core functions such as track movement and vibration de-icing, but also allows for flexible adjustment of the power supply mode according to the intensity of the work. A single battery can meet the needs for short-distance operations, while dual-battery power is used for long-distance, high-intensity operations. This effectively avoids work interruptions caused by insufficient power when using a single battery, significantly improving the device's adaptability and endurance in different working environments such as complex terrain and remote lines. In addition, the symmetrical arrangement of the two sets of power batteries facilitates the balance of the device. The vibration de-icing device for this power transmission line has a clear layout of its components on the first support frame. The tracked walking component, the vibration de-icing mechanism, and the clamping and limiting mechanism are respectively located in their respective working areas, with clear division of labor and coordinated cooperation. The bearing seats are set on the crossbeam of the first support frame through clamping plates. The mounting frame, transfer frame, and other components are fixed by bolts and other connection methods, which ensures the stability of the overall structure and enables the device to operate stably during operation, thereby improving the reliability of the operation.

Detailed Implementation

[0017] The present invention will be further described below with reference to embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-7 This invention provides a vibration de-icing device for power transmission lines, including a first support frame 1. The first support frame 1 is provided with a tracked walking assembly 3, a vibration de-icing mechanism 4, and a clamping and limiting mechanism 5. The tracked walking assembly 3 is used to adjust the working position of the power transmission line and can crush the ice layer outside the power transmission line to break the ice layer. The vibration de-icing mechanism 4 is used to generate resonance to cause the ice layer to disintegrate and fall off. The clamping and limiting mechanism 5 is used to clamp the power transmission line. The tracked walking assembly 3 is installed in the first working area of ​​the first support frame 1, and the vibration de-icing mechanism 4 and the clamping and limiting mechanism 5 are arranged in the second working area of ​​the first support frame 1. The vibration de-icing mechanism 4 is located above the clamping and limiting mechanism 5.

[0020] Among them, existing vibration-free de-icing machines usually rely on hard methods such as mechanical crushing or scraping to remove ice. These methods exert direct and concentrated force on the ice layer and cable. When the ice layer is tightly bonded to the cable, hard de-icing can easily cause the cable surface to bear excessive pressure or friction, which may cause wear of the cable's outer insulation layer, sheath rupture, or even damage to the internal conductor. In this example, after the tracked walking component 3 initially crushes the surface ice shell, the vibrating de-icing mechanism 4 generates resonance through high-frequency vibration. Utilizing the different natural frequencies of the ice layer and the cable, the ice layer cracks due to resonance and disintegrates. The vibration energy mainly acts on the ice layer, with less direct force on the cable. At the same time, the clamping and limiting mechanism 5 can stably clamp the cable, avoiding excessive shaking of the cable during the de-icing process and thus avoiding additional stress. This significantly reduces mechanical damage to the cable and achieves a gentler and safer de-icing effect. By setting the tracked walking component 3, the working position of the device on the power transmission line can be flexibly adjusted to ensure that the device can accurately reach the area that needs de-icing and avoid omissions. Moreover, each mechanism is set in a separate area on the first support frame 1 with clear division of labor, which reduces mutual interference during operation and improves the overall work efficiency. By setting the clamping and limiting mechanism 5, the power transmission line can be firmly clamped, providing stable support for the device during operation, preventing the device body from shifting, shaking or even falling off due to vibration or movement, ensuring the stability of components such as the vibrating de-icing mechanism 4 during operation, and ensuring the smooth progress of de-icing work.

[0021] Please see Figures 1-4 The tracked walking assembly 3 includes a track 31, a drive shaft 32, a driven shaft 33, a bearing housing 34, and a drive motor 35. The drive shaft 32 and the driven shaft 33 are mounted on the first support frame 1 in conjunction with the bearing housing 34. The output end of the drive motor 35 is connected to the drive shaft 32 for transmission. A clamping plate 341 is welded to one side of the bearing housing 34. The bearing housing 34 and the clamping plate 341 are mounted on the crossbeam of the first support frame 1. The surface of the track 31 is provided with friction protrusions 311.

[0022] In this embodiment, the tracked walking assembly 3 consists of a track 31, a drive shaft 32, a driven shaft 33, a bearing seat 34, and a drive motor 35. The output end of the drive motor 35 is connected to the drive shaft 32. The drive shaft 32 and the driven shaft 33 are mounted on the first support frame 1 in conjunction with the bearing seat 34. This structural design enables efficient power transmission, ensures stable operation of the track 31, ensures smooth movement of the device on the power transmission line, reduces the likelihood of jamming, and improves the mobility reliability of the device. A clamping plate 341 is fixedly connected to one side of the bearing housing 34 with bolts, and the clamping plate 341 is set on the crossbeam of the first support frame 1. The clamping plate 341, which is fixedly connected by bolts, enhances the stability of the connection between the bearing housing 34 and the first support frame 1, improves the overall structural strength of the track walking assembly 3, can effectively withstand multiple loads during operation, reduce the loosening of parts caused by vibration and other factors, and extend the service life of the assembly. At the same time, the bolt connection method facilitates the subsequent disassembly and maintenance of the clamping plate 341. By providing friction protrusions 311 on the surface of the track 31, the friction between the track 31 and the power transmission line and the ice layer can be increased, making it less likely to slip when crushing the ice layer. This not only ensures stable movement on the power transmission line, but also enhances the crushing and breaking effect on the ice layer, thus improving the efficiency of initial de-icing.

[0023] Please see Figures 1-7 The vibratory de-icing mechanism 4 includes a mounting frame 41, which is bolted to the first support frame 1. A transmission frame 42 and a vibration motor 43 are mounted on the mounting frame 41. The vibration motor 43 is mounted on the transmission frame 42. A transmission plate 44 is bolted to the bottom of the transmission frame 42. A clamping and limiting mechanism 5 is mounted on the transmission plate 44. The clamping and limiting mechanism 5 mainly consists of a movable arm 51, a clamping roller 53, and an adjusting plate 55. The movable arm 51 is hinged to the two side walls of the transmission plate 44. Plate 55 is hinged to connecting rod 54 and movable arm 51. Clamping rollers 53 are arrayed in U-shaped clamping frame 52. U-shaped clamping frame 52 is bolted to one side of movable arm 51 on both sides and to the lower end of adjusting plate 55 located above the middle of movable arm 51 on both sides. Telescopic rod 56 is installed at the lower end of transfer plate 44. Telescopic rod 56 is bolted to the lower end of transfer plate 44. Transition block 561 is provided at the output end of telescopic rod 56. Transition block 561 is bolted to the middle position of adjusting plate 55.

[0024] In this embodiment, the vibration motor 43 is installed on the transmission frame 42. The energy generated by the vibration can be transmitted to the clamping and limiting mechanism 5 and the ice layer on the transmission line through the transmission frame 42 and the transmission plate 44 in sequence. The energy loss is small, and it can efficiently induce resonance of the ice layer and the line body, so as to promote the rapid disintegration and fall of the ice layer and greatly improve the de-icing efficiency. In this embodiment, the clamping and limiting mechanism 5 adopts a gravity-adaptive method, which can further reduce damage to the cable. The movable arm 51 is hinged to the transmission plate 44, and with the extension and retraction adjustment of the telescopic rod 56, the opening and closing angle can be automatically adjusted according to the diameter of the transmission line, avoiding the squeezing stress caused by rigid clamping. The clamping rollers 53 arrayed in the U-shaped clamping frame 52 flexibly fit against the cable surface under the action of gravity, which not only ensures clamping stability, but also reduces friction damage to the cable through the rolling of the rollers. When the device is displaced due to vibration or line undulation, the clamping rollers 53 can adaptively adjust with the cable posture to always maintain uniform force and avoid cable sheath damage caused by excessive local pressure. Compared with rigid clamping structures without adaptive function, it can achieve safer limiting protection for cables of different diameters and under different working conditions. The mounting frame 41 of the vibration de-icing mechanism 4 is bolted to the first support frame 1. The lower part of the transmission frame 42 is bolted to the transmission plate 44. The telescopic rod 56 is also bolted to the lower end of the transmission plate 44. By using bolts to connect the various components, not only is the connection stable, ensuring the stability of the mechanism during vibration operation, but it also facilitates the disassembly, maintenance and replacement of components in the later stage, reducing maintenance costs.

[0025] Please see Figure 1 and Figure 2 The first support frame 1 has two symmetrical sets. The two sets of first support frames 1 are hinged to the two sets of second support frames 11 by means of hinge blocks 12. Each set of second support frames 11 is equipped with a power supply battery 2.

[0026] In this embodiment, the first support frame 1 is provided with two symmetrical sets, and is hinged to the two sets of second support frames 11 through the hinge block 12. The hinge structure allows the two sets of first support frames 1 and second support frames 11 to rotate relative to each other, which can better adapt to different working scenarios and line layouts, and improve the flexibility and applicability of the device. The two sets of second support frames 11 are each equipped with a power supply battery 2. The power supply battery 2 can not only provide stable power support for the components of the device and avoid the interruption of operation due to insufficient power supply of a single battery, but also extend the battery life of the device, ensure the continuity of de-icing operation, reduce the trouble of frequent battery replacement or charging, and improve work efficiency. The two sets of first support frames 1 and second support frames 11, which are symmetrically arranged, form a symmetrical structural layout. With the symmetrical installation of the power supply battery 2, the device is subjected to more even force and the center of gravity is more stable during operation. This reduces swaying or tilting caused by the shift of the center of gravity, and ensures the stability and safety of the device operation.

[0027] In the above scheme, it should be noted that: the drive motor 35 in this application uses the ZYT series as a DC motor and is equipped with a TB6600 series PWM DC motor driver. The input end of the driver is connected to a 36V power supply battery, and the output end is connected to the positive and negative terminals of the motor. The speed is adjusted by receiving PWM signals. The control signal end of the driver is connected to a wireless module with ESP32 as the main controller. The module receives remote commands through 4G and converts them into forward and reverse rotation signals and speed signals to realize the start, stop, speed adjustment and direction control of the track 31. The vibration motor 43 uses a YZU-5-2 series three-phase asynchronous motor, paired with an SSR-3P series three-phase solid-state relay. The relay input is connected to the relay drive module of the main control unit, and the output is connected in series with the motor power supply circuit. After the remote command is transmitted to the main control unit via the wireless module, the motor can be started and stopped by controlling the relay. At the same time, the input voltage can be changed by combining the voltage regulation module to flexibly adjust the excitation frequency to adapt to different ice layer characteristics. In addition, the integrated status feedback module transmits the motor operating parameters back in real time to ensure the stability and accuracy of remote control and meet the unmanned control requirements of high-altitude operations on power transmission lines. It should be noted that all the components mentioned above are existing mature products, and their specific connection technologies will not be described in detail here.

[0028] Working principle and usage process of this invention: First, using the hinge structure formed by the hinge block 12 between the first support frame 1 and the second support frame 11, the second support frame 11 is unfolded according to the actual layout of the power transmission line to be de-iced, so that it can be adapted to the layout of the power transmission line to be de-iced. At the same time, the power supply batteries 2 on the two sets of second support frames 11 are activated to provide power support for each component of the device and ensure sufficient power. Secondly, since the clamping and limiting mechanism 5 adopts a gravity adaptive method, when the transmission line is clamped between the three sets of clamping rollers 53, and the telescopic rod 56 moves vertically, the adapter block 561 at one end drives the adjusting plate 55 to move. The adjusting plate 55 drives the movable arms 51 on both sides to open and close around the hinge point of the side wall of the transmission plate 44 through the connecting rod 54, until the clamping rollers 53 in the U-shaped clamping frame 52 are in close contact with the transmission line, thus completing the stable clamping of the transmission line and providing stable support for subsequent operations. Then, the drive motor 35 starts, and the power is transmitted to the drive shaft 32. The drive shaft 32, together with the driven shaft 33 and the bearing seat 34, drives the track 31 to rotate, so that the device moves along the transmission line. During the movement, the friction protrusions 311 on the surface of the track 31 increase the friction with the ice layer, crushing the ice layer outside the transmission line and causing the ice layer to break up initially. After the ice layer is initially crushed, the vibration motor 43 is started. The vibration energy generated is transmitted to the clamping and limiting mechanism 5 and the ice layer on the transmission line through the transmission frame 42 and the transmission plate 44 in sequence, causing the ice layer to resonate and further disintegrate and fall off the initially crushed ice layer. During this process, the clamping and limiting mechanism 5 continues to firmly clamp the transmission line to prevent it from shifting or shaking due to vibration, ensuring the effect of vibration de-icing. At this time, the track walking component 3 continues to adjust the working position of the device on the transmission line to ensure that all areas that need to be de-iced are covered. The track 31 crushing and vibration de-icing work together to completely remove the ice until the de-icing work of this section of the transmission line is completed. Finally, after de-icing is completed, the vibration motor 43 and drive motor 35 stop running, the clamping limit mechanism 5 releases the clamp on the power transmission line, and the power supply battery 2 is turned off, completing the operation and removing or transferring the device to the next section of the line to be de-iced.
