[0002] Transmission line deicing refers to taking certain measures to remove ice formed on transmission lines due to cold weather. When the temperature is low and the humidity is high, transmission lines are easily covered by ice. The presence of ice can pose many hazards to transmission lines. For example, it increases the weight of the line, which may cause the tower to collapse under the heavy load; uneven distribution of ice may cause uneven stress on the line, causing faults such as line breakage; at the same time, ice may also affect the performance of insulators, reduce insulation levels, and increase the risk of leakage and short circuits. In order to ensure the safe operation of transmission lines, deicing operations are required. Common deicing methods include thermal ice melting and mechanical deicing. Transmission line deicing equipment is a device specifically used for line deicing.

The utility model clamps the power transmission line using a first clamping roller and a second clamping roller, activates a servo motor, and drives the first clamping roller to rotate, thereby moving the deicing device along the power transmission line, enabling deicing of the power transmission line over long distances. A hydraulic vibrating rod is used to knock ice on the power transmission line, thereby crushing ice. A scraper ring is used to scrape ice off the surface of the power transmission line. The mounting block, mounting seat, first spring, limit block, plug rod, and slot cooperate to facilitate the fixing and removal of the upper and lower housings, making installation simple and convenient.

[0042] In this embodiment, a limiting ring 14 is provided on both sides of the rotating wheel 9. The limiting ring 14 is threadedly connected to the bottom shaft 8.

[0043] In this embodiment, the inner walls of both sides of the protective frame 3 are fixedly connected with multiple telescopic rods 10, and the ends of the multiple telescopic rods 10 on the same side are fixedly connected with the same pressure ring 11.

When the cooling fan 17 is started, the heat generated in the control box 18 is transported to the interior of the protective frame 3 through the top pipe 16. The battery inside the control box 18 can provide power for the device. The coordinated use of the air inlet 19 and the cooling fan 17 can dissipate the heat generated by the internal circuit of the control box 18, and the top pipe 16 can be used to transport the heat produced by the internal circuit devices of the control box 18 to the interior of the protective frame 3, thereby facilitating the preheating of the crushing ring 5 inside the protective frame 3, facilitating the crushing ring 5 to break ice, and also facilitating the melting of ice on the transmission line.

[0046] In this embodiment, a transverse plate 21 is provided on one side of the protective frame 3, and the transverse plate 21 and the protective frame 3 form an integrated structure, so that the transverse plate 21 and the protective frame 3 are not easy to break during long-term use. A threaded rod 22 is threadedly connected to the transverse plate 21, and the threaded rod 22 passes through the transverse plate 21. The bottom end of the threaded rod 22 is rotatably connected to the scraper 23, and the vertical center line of the scraper 23 coincides with the center axis of the threaded rod 22. When the device moves, the scraper 23 is in contact with the power transmission line, which can scrape off the broken ice on the conveyor line and improve the de-icing effect of the device. Before using the device, the height of the scraper 23 can be adjusted by rotating the threaded rod 22 and cooperating with the transverse plate 21 to ensure that the scraper 23 can contact the top of the power transmission line when the device moves.

[0047] Another aspect of this embodiment provides a method for breaking ice using the above device, which specifically includes the following steps:

[0048] S1. Start the drive motor inside the control box 18 to rotate the propeller 20 and move the power transmission line deicing device to the power transmission line so that each power transmission line is located between the runner 9 and the crushing ring 5 of each protection frame 3;

[0049] S2. The connecting plate 7 is raised by the lifting rod 6, driving the runner 9 on the bottom shaft 8 to rise, so that the runner 9 contacts the transmission line and presses the crushing ring 5 onto the transmission line;

[0050] S3. Start the motor 1 to rotate the horizontal shaft 2, which drives the rotating drum 4 to rotate, so that the power transmission line deicing device moves along the power transmission line, and squeezes the ice on the surface of the power transmission line through the crushing ring 5, thereby deicing the power transmission line;

[0051] S4. When the power transmission line deicing device moves, the scraper 23 contacts the top of the power transmission line and scrapes off the ice on the power transmission line.

[0052] Working principle: When using this device, firstly, through the external remote control device, in conjunction with the signal receiver and central processor inside the control box 18, the device can be remotely controlled, the drive motor inside the control box 18 is started, the propeller 20 can be rotated, and the device is moved to the high transmission line by the rotation of the propeller 20, so that each transmission line is located corresponding to each protection frame 3, the transmission line is clamped between the protection frame 3 and the bottom shaft 8, and the connecting plate 7 is raised by the lifting rod 6, driving the bottom shaft 8 and the rotating wheel 9 to move upward. Lift, clamp each transmission line between the runner 9 and the crushing ring 5. The annular groove on the runner 9 is convenient for clamping the transmission line to prevent the transmission line from shaking left and right. Install the device on the transmission line. It is worth noting that the protective frame 3 at one end of the horizontal axis 2 is equipped with a motor 1, and the protective frame 3 at the other end is equipped with a lifting rod 6, a connecting plate 7, and a bottom shaft 8 and other devices, so that the weight of the two ends is the same. At the same time, the use of the connecting rod 15 is conducive to ensuring the stability of the device on the transmission line. Start the motor 1 to rotate the horizontal axis 2, driving the drum 4 to rotate. In conjunction with the rotation of the runner 9 on the bottom shaft 8, the device can be moved along the transmission line. The crushing ring 5 on the outside of the drum 4 can squeeze the ice on the surface of the transmission line, thereby crushing the ice on the transmission line, and achieving de-icing of the output line while moving, making de-icing more convenient and improving the de-icing efficiency. The limit ring 14 can limit the runner 9 to ensure the stability of the limit ring 14 during rotation and prevent the limit ring 14 from moving laterally on the bottom shaft 8. The spring 12 and the telescopic rod 10 are used in conjunction with each other. The pressure ring 11 can be moved toward the center of the crushing ring 5, and the protrusion 13 on the pressure ring 11 can be used to squeeze the ice on both sides of the transmission line, further improving the ice crushing ability of the device. When the device moves, the scraper 23 is in contact with the transmission line, which can scrape off the broken ice on the conveyor line and improve the de-icing effect of the device. Before using the device, the height of the scraper 23 can be adjusted by rotating the threaded rod 22 and using the cross plate 21 to ensure that the scraper 23 can contact the top of the transmission line when the device moves.

[0053] The internal battery of the control box 18 can provide power for the device. The heat generated by the internal circuit of the control box 18 can be dissipated by the coordinated use of the air inlet 19 and the cooling fan 17. The heat generated by the internal circuit components of the control box 18 can be transported to the inside of the protective frame 3 by the top pipe 16, thereby facilitating the preheating of the crushing ring 5 inside the protective frame 3, facilitating the crushing ring 5 to break ice, and also facilitating the melting of ice on the transmission line.

When the power transmission line deicing device moves, the scraper (23) contacts the top of the power transmission line and scrapes off the ice on the power transmission line.
