Description

Technical Field

[0001] This utility model belongs to the field of power line de-icing technology, and in particular relates to a power operation and maintenance de-icing device. Background Technology

[0002] In cold winters, when air humidity is high, the surface of power transmission lines is prone to icing. As the temperature continues to drop, the amount of ice on the surface of the transmission lines gradually increases, resulting in an increasingly heavy load on the transmission lines. This can even lead to serious consequences such as the transmission lines being crushed and the towers collapsing, posing a great safety hazard.

[0003] Among them, CN219678076U discloses a de-icing device for power transmission line maintenance, which effectively solves the problems of high difficulty, time-consuming and labor-intensive de-icing of power transmission lines, inconvenience in quickly removing ice from the same transmission line, and the risk of falling snow or ice injuring workers, resulting in accidental injuries and high manpower consumption. This power transmission line maintenance de-icing device, through the cooperation of a drive unit and transmission mechanism, uses a rotating roller and a top-tightening wheel to move the base and top boxes while the ice-scraping unit rotates to scrape away the ice covering the power lines, reducing energy consumption. With the help of a stop block, the rotating ice-scraping plate scrapes off the covering ice, resulting in high de-icing efficiency without damaging the power lines. Combined with the abrasive plate, it can further scrape away residual ice on the power lines, ensuring effective de-icing while being more energy-efficient.

[0004] When using this de-icing device, it was found that the top box 2 and bottom box 1 are clamped onto the wire to be de-iced by fixing lugs 17 with bolts and nuts. The wire is wrapped by the scraping plate 6 and the rotating plate 5. The outer surfaces of the mounting roller 3 and the tightening wheel 4 are in contact with the outer surface of the wire, thus clamping and de-icing the wire. However, it was found that it can only de-ic the wire of a single diameter. When de-icing wires of other diameters, the fixed structure of clamping the wire means that the diameter of the wire cannot be changed according to different diameters, making it unable to handle de-icing of wires of various diameters. Its applicable range is relatively narrow. In addition, the bolts and nuts need to be disassembled for each de-icing operation, which is cumbersome and inconvenient. Therefore, we need to design a power maintenance de-icing device to improve the above problems. Utility Model Content

[0023] Figure 1-3 This invention illustrates a power maintenance de-icing device according to an embodiment of the present invention, comprising: a variable-diameter walking component 1, a variable-diameter de-icing component 2, a drive component 3, and a power line 4. Specifically, the variable-diameter walking component 1 includes a C-shaped housing 11, a fixed wheel assembly, and a movable wheel assembly. There are two movable wheel assemblies. The fixed wheel assembly and the two movable wheel assemblies are arranged in a circular array on the surface of the C-shaped housing 11. Specifically, multiple anti-drop balls 5 are evenly arranged on the inner and outer surfaces of the left end of the C-shaped housing 11. Two sets of anti-drop balls 5 are arranged in a circular array on the surface of the C-shaped housing 11. Through the arrangement of the anti-drop balls 5, when the variable-diameter de-icing component 2 rotates with the drive component 3, the anti-drop balls 5 roll within the cavity of the C-shaped rotating ring 21, thereby reducing the impact on the C-shaped rotating ring 21. The friction between the C-shaped housing 11 and the C-shaped rotating ring 21 during rotation, and the anti-drop ball bearing 5 also prevents the C-shaped rotating ring 21 from falling off the surface of the C-shaped housing 11. Specifically, the fixed wheel assembly includes a fixed wheel 12, a fixed rod 13, a first motor 14, and a mounting plate 15.

There are two drive assemblies 3, arranged in a ring array on the surface of the variable-diameter walking assembly 1. The drive assemblies 3 drive the variable-diameter de-icing assembly 2 to rotate on the left side of the variable-diameter walking assembly 1. Specifically, each drive assembly 3 includes a motor housing 31, a drive gear 32, and a second motor 33. The motor housing 31 is fixedly mounted on the variable-diameter walking assembly 1, and the second motor 33 is fixedly mounted inside the motor housing 31.

The C-shaped rotating ring 21 is rotatably connected to the left side of the variable-diameter walking assembly 1, and the three sets of de-icing assemblies are arranged in a ring array on the C-shaped rotating ring 21. 1. On the surface, a C-shaped external gear 26 is fixedly installed on the surface of a C-shaped rotating ring 21. The C-shaped external gear 26 is meshed with two drive gears 32. The de-icing assembly includes a second movable rod 22, a second nut 23, a base 24, and a de-icing claw 25. A through hole 22 is provided on the surface of the C-shaped rotating ring 21 for the second movable rod 22 to slide. The second movable rod 22 slides in the inner cavity of the through hole 22.

[0026] The wire 4 is installed inside the variable-diameter walking assembly 1 and the variable-diameter de-icing assembly 2.

[0027] Working principle: When using this utility model, the user first places the wire 4 inside the cavity of the variable diameter walking component 1 and the variable diameter de-icing component 2, moves the wire 4 until it is in contact with the surface of the fixed wheel 12, slides the first movable rod 16 up and down to make the movable wheel 18 contact with the surface of the wire 4, and locks the first movable rod 16 on the surface of the C-shaped housing 11 by tightening the two first nuts 17. The wire 4 is clamped by the cooperation of the two movable wheels 18 and the fixed wheel 12, thereby achieving the function of the variable diameter walking component 1 moving on wires 4 of different diameters; then, slide the second movable rod 22 up and down to make the de-icing claw 25 fixed on it contact with the surface of the wire 4, and tighten the second nut 23 to make the wire 4 contact with the fixed wheel 12. The corresponding second movable rod 22 is locked on the surface of the C-shaped rotating ring 21; then the second motor 33 is started, and the output shaft on the second motor 33 drives the drive gear 32 to rotate, thereby driving the outer gear 26 of the C-shaped ring and the C-shaped rotating ring 21 to rotate, which in turn drives the de-icing claw 25 to rotate on the surface of the wire 4 to remove ice; finally, the first motor 14 is started, driving the fixed wheel 12 to roll on the surface of the wire 4, thereby driving the C-shaped outer shell 11 to walk on the surface of the wire 4; this de-icing device can clamp and move wires 4 of different diameters and perform ring-shaped de-icing, improving the de-icing effect. It should be noted that a battery is provided on the surface of the C-shaped outer shell 11 to provide power to the components, but it is not shown in the figure.

[0028] In summary, this power maintenance de-icing device can clamp and move on wires 4 of different diameters through the variable diameter walking component 1, and drive the variable diameter de-icing component 2 to rotate on the surface of the wires 4 through the drive component 3, thereby realizing the ring-shaped de-icing of wires 4 of different diameters.
