Description

Technical Field

[0001] This utility model relates to a de-icing device for high-voltage transmission lines, belonging to the field of high-voltage transmission line de-icing technology. Background Technology

[0002] High-voltage transmission lines are a core component of power transmission and play a vital role in the power system. In southern my country, low winter temperatures, abundant rainfall, and high humidity make them prone to icing. If ice buildup on lines is not removed promptly, exceeding the permissible ice thickness can cause incalculable damage to the power system.

[0003] Currently, cable de-icing methods mainly include AC short-circuit current de-icing and DC current de-icing. AC short-circuit current de-icing is a complex and time-consuming operation with low efficiency. DC current de-icing is more practical than AC current de-icing, but it requires the iced line to be disconnected from the main power grid during operation, which can affect local power supply to some extent. Furthermore, current DC de-icing equipment is relatively large, requiring large vehicles for transportation, resulting in poor mobility and making it difficult to reach mountainous or other terrain-challenged areas for de-icing operations. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a de-icing device for high-voltage transmission lines that utilizes ultrasonic waves for ice melting and employs mechanical crushing by pressure rollers for auxiliary de-icing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a high-voltage transmission line de-icing device, comprising: The drone has a lightweight modular APU unit and an ultrasonic generator fixed underneath it. A connecting cable, which is fixed to the ultrasonic generator; A housing, which is suspended from the lower end of the connecting cable; The housing has a downward-facing cable groove, and a mounting block is provided on the top of the cable groove. Multiple ultrasonic transducers are mounted on the mounting block.

[0006] When the housing is connected to the high-voltage transmission line via the cable slot, the ultrasonic transducer faces the transmission line.

[0007] Preferably, a sliding groove is provided on the housing above the receiving groove, the mounting block is slidably connected in the sliding groove, and an adjusting bolt is engaged with the top of the housing, the threaded end of the adjusting bolt extending into the sliding groove and rotatably connected to the mounting block.

[0008] Preferably, a plurality of guide rods are fixed on the side wall of the mounting block, and the upper ends of the plurality of guide rods slide on the housing.

[0009] Preferably, connecting rods are provided on both sides of the housing, the upper ends of the two connecting rods are connected to the housing, and the lower ends of the two connecting rods are fixedly connected to counterweights.

[0010] Preferably, a rotating rod is fixedly connected to the upper end of the connecting rod, and the rotating rod is rotatably connected to the housing.

[0011] Preferably, a sliding frame is slidably connected to both sides of the housing and located on both sides of the wire groove, and the two sliding frames extend into the wire groove and are rotatably connected to a plurality of pressure rollers; The sliding frame has rollers rotatably connected to its side wall, and the rollers roll on the side wall of the rotating rod.

[0012] Preferably, an inclined wall is provided on the sliding frame and below the pressure roller; When the high-voltage transmission line enters the cable tray, the high-voltage transmission line is pushed open by the inclined wall against the two sliding frames.

[0013] Preferably, multiple guide rods are fixed on both sides of the housing, and the sliding frame is slidably sleeved on the guide rods.

[0014] Preferably, the connecting cable includes a power supply cable, a signal cable, and a steel wire rope.

[0015] Preferably, the upper surface of the housing is fixed with ear blocks for connecting the connecting cable on both sides.

[0016] Compared with existing technologies: 1. This utility model uses a drone to carry de-icing equipment to the vicinity of a target high-voltage power line. Utilizing the cooperation between the housing and the high-voltage power line, as well as the ingenious linkage mechanism between the sliding frame, rollers, connecting rods, and counterweight, the sliding frame is first guided by the inclined wall to open as the high-voltage power line enters the housing. The rollers press against the connecting rods, causing the counterweight to swing. After the high-voltage power line has fully entered, the weight of the counterweight causes the connecting rods to press against the rollers in the opposite direction, thereby pressing the pressure rollers on the two sliding frames tightly against both sides of the high-voltage power line. This can stably fix the housing to the high-voltage power line and effectively prevent the housing from tipping to one side and falling off the high-voltage power line.

[0017] 2. This utility model uses an ultrasonic generator to transmit signals to multiple ultrasonic transducers via a signal cable inside the connecting cable. The signals are converted into ultrasonic waves, which are used to melt the ice on the high-voltage transmission line. At the same time, the drone flies slowly along a preset route, causing its shell to slide along the high-voltage transmission line. This allows the ultrasonic transducers to perform de-icing operations on different parts of the high-voltage transmission line. In addition, the pressure roller works with the ultrasonic transducers to break up the melted ice until the de-icing work of the entire high-voltage transmission line is completed, which greatly improves the de-icing efficiency and ensures the safe operation of the high-voltage transmission line.

[0020] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0021] Example 1 like Figures 1-6 As shown in this embodiment, a high-voltage power transmission line de-icing device includes a drone 1. A lightweight modular APU unit 2 and an ultrasonic generator 3 are fixed below the drone 1. A connecting cable 4 is fixed on the ultrasonic generator 3. The connecting cable 4 includes a power supply cable, a signal cable, and a steel wire rope, which serves as a load-bearing element. A housing 5 is suspended from the lower end of the connecting cable 4. The housing 5 has a downward-facing cable-receiving groove 501. A mounting block 6 is provided on the top of the cable-receiving groove 501, and multiple ultrasonic transducers 7 are provided on the mounting block 6. When the housing 5 is connected to the high-voltage power transmission line through the cable-receiving groove 501, the ultrasonic transducers 7 face the power transmission line.

[0022] Both sides of the upper surface of the housing 5 are fixed with ear blocks 503 for connecting the connecting cable 4.

[0023] like Figure 1 As shown, the housing 5 is suspended below the drone 1 using the connecting cable 4. The drone 1 moves the housing 5 to the high-voltage power line. The housing 5 is placed on the high-voltage power line using the cable tray 501. The drone 1 drives the housing 5 to slide along the high-voltage power line. During this process, the ultrasonic generator 3 converts electrical energy into a high-frequency AC signal that matches the ultrasonic transducer 7, driving the ultrasonic transducer 7 to work and using ultrasonic waves to melt ice.

[0024] Example 2 like Figure 4 and Figure 5 As shown, based on Embodiment 1, in this embodiment, a sliding groove 502 is provided on the housing 5 above the receiving groove 501, the mounting block 6 is slidably connected in the sliding groove 502, and an adjusting bolt 8 is engaged with the top of the housing 5. The threaded end of the adjusting bolt 8 extends into the sliding groove 502 and is rotatably connected to the mounting block 6. When the adjusting bolt 8 is rotated, the adjusting bolt 8 moves axially on the housing 5, causing the adjusting bolt 8 to drive the mounting block 6 to slide in the slide groove 502, so as to adjust the distance between the ultrasonic transducer 7 and the high-voltage transmission line in the cable tray 501.

[0025] Multiple guide rods 601 are fixed on the side wall of the mounting block 6. The upper ends of the multiple guide rods 601 slide on the housing 5, so that the mounting block 6 can slide smoothly in the slide groove 502.

[0026] Example 3 like Figures 1-6 As shown, based on Embodiment 1, in this embodiment, connecting rods 9 are provided on both sides of the housing 5. The upper ends of the two connecting rods 9 are connected to the housing 5, and the lower ends of the two connecting rods 9 are fixedly connected to counterweights 10. By using the two counterweights 10 to counterweight both sides of the housing 5, the housing 5 can be hung on the high-voltage transmission line, preventing the housing 5 from tipping over to one side and falling off the high-voltage transmission line.

[0027] A rotating rod 901 is fixedly connected to the upper end of the connecting rod 9, and the rotating rod 901 is rotatably connected to the housing 5.

[0028] Sliding frames 11 are slidably connected to both sides of the housing 5 and located in the wire groove 501. The two sliding frames 11 extend to the wire groove 501 and are rotatably connected to multiple pressure rollers 12. Among them, a roller 13 is rotatably connected to the side wall of the sliding frame 11, and the roller 13 rolls on the side wall of the rotating rod 901.

[0029] An inclined wall 14 is provided on the sliding frame 11 and below the pressure roller 12; When the high-voltage transmission line enters the cable tray 501, the high-voltage transmission line is pushed open by the inclined wall 14 against the two sliding frames 11. The high-voltage transmission line moves between the two sliding frames 11. At the same time, the roller 13 presses against the connecting rod 9, causing the connecting rod 9 to swing outward with the counterweight 10. Using the gravity of the counterweight 10, the connecting rod 9 generates a reverse pressing force on the roller 13. In this way, the pressure rollers 12 on the two sliding frames 11 press against both sides of the high-voltage transmission line. After the ultrasonic melting of the ice, the pressure rollers 12 immediately squeeze and break the loose ice layer, breaking the melted ice, thus playing an auxiliary role in de-icing.

[0030] Multiple guide rods 15 are fixed on both sides of the housing 5, and the sliding frame 11 is slidably sleeved on the guide rods 15.

[0031] Work process: During high-voltage power line de-icing operations, UAV 1 is first activated, using the lightweight modular APU unit 2 beneath UAV 1 to provide auxiliary power, enabling UAV 1 to carry the de-icing equipment and fly to the vicinity of the target high-voltage power line. The housing 5 is suspended below UAV 1 via connecting cable 4. Using the flight control of UAV 1, the cable tray 501 of housing 5 is aligned with the high-voltage power line and slowly lowered, allowing the high-voltage power line to enter the cable tray 501. As the high-voltage power line enters the cable tray 501, it first contacts the inclined wall 14 on the sliding frame 11. Guided by the inclined wall 14, the two sliding frames 11 are forced to open outwards along the guide rod 15, gradually moving the high-voltage power line between the two sliding frames 11. Simultaneously, rollers 13 on the side walls of the sliding frames 11 roll on the side walls of the connecting rod 9. As the sliding frames 11 open, the rollers 13 press against the connecting rod 9, causing the connecting rod 9, along with the counterweight 10, to swing outwards. Once the high-voltage transmission line is fully inserted into the cable tray 501, the counterweight 10 exerts a counter-pressure force on the roller 13, causing the pressure rollers 12 on the two sliding frames 11 to press tightly against both sides of the high-voltage transmission line, thus stably fixing the housing 5 to the high-voltage transmission line and preventing it from tipping over and falling off. The ultrasonic generator 3 is then activated, and the signal generated by it is transmitted through the signal cable in the connecting cable 4 to multiple ultrasonic transducers 7 on the mounting block 6. The ultrasonic transducers 7 convert the signal into ultrasonic waves, using the energy of these waves to melt the ice on the high-voltage transmission line. Simultaneously, the drone 1 flies slowly along a preset route, propelling the housing 5 along the high-voltage transmission line, allowing the ultrasonic transducers 7 to perform de-icing operations on different parts of the high-voltage transmission line until the entire high-voltage transmission line is de-iced.
