[0002] With the development of technology, a lot of disc-shaped insulators are hung on one end of the high-voltage power line connection tower. It is used to increase the creepage distance. It is usually made of glass or ceramics. It is called an insulator. Insulators play the role of supporting the conductors and preventing the current from returning to the ground in overhead transmission lines.
[0003] In cold rainy and snowy weather, the surface of the insulator is prone to ice, the load on the conductor is increased, the resistivity is reduced, and even accidents such as short circuit and leakage may occur. For example, in the patent application with the authorization publication number CN218647706U and the authorization publication date 2023-03-17, entitled "A Kind of Ice-Melting Composite Insulator", an ice-melting shell is installed on the top of the umbrella skirt. The surface of the ice-melting shell is smooth and it is not convenient to retain rainwater. At the same time, a heating wire is arranged inside the ice-melting shell. Through the arrangement of the solar panel, it is convenient to add the ice-melting shell to accelerate the melting of ice, effectively reduce the accumulation of rain and snow on the surface of the composite insulator, and affect the use of the composite insulator. In the actual use of the above-mentioned device, the heating of the heating wire causes the ice layer to melt. During the melting process, there is a situation where the ice layer close to the insulator can be quickly melted while crushed ice will remain on the outside. The crushed ice will extend the working time of the heating wire and the heating wire has a heavy workload.
[0004] Therefore, we propose an ice-melting composite insulator to solve the above problems. Utility Model Content

[0020] 3. Beneficial effects:
[0021] Compared with the prior art, the utility model adopts the technical solution provided by the utility model, and the ice-melting composite insulator of the utility model melts the ice layer on the surface of the insulator by the cooperation of the heating wire and the heat-conducting sheet, and promotes the rapid shedding of the broken ice to improve the effect of melting the ice column. The specific contents are as follows:
[0022] When the heating wire is energized, the heat generated by the heating wire is transferred to the heat conductive sheet, and the heat is evenly dispersed on the insulator under the action of the heat conductive sheet, so that the ice layer near the insulator is melted quickly, effectively reducing the accumulation of rain and snow on the surface of the composite insulator, reducing the load and ensuring safety;
[0023] When there is wind, the wind scoops with equal angles are driven by the wind to rotate the movable ring between the two limit rings, thereby driving the vibration mechanism to rotate synchronously. During the rotation of the vibration mechanism, the movable rod is driven to slide on the force-bearing plate. When the movable rod slides on the arc-shaped side of the driving block, the pressure spring is compressed.

[0035] Combination Figure 1-2 As shown, the heating wire 4 is connected to the solar panel in the prior art, and the heating wire 4 is energized, and the heat generated by the heating wire 4 is transferred to the heat conductive sheet 5. Under the action of the heat conductive sheet 5, the heat is evenly dispersed on the insulator, so that the ice layer near the insulator is melted quickly, and the accumulation of rain and snow on the surface of the composite insulator is effectively reduced, thereby reducing the load and ensuring safety.
[0036] The force-bearing plate 6 is fixedly mounted on the middle upper end of the core rod 1, and a rotating mechanism 7 is arranged above the force-bearing plate 6. The cooperation of the rotating mechanism 7 and the force-bearing plate 6 generates vibration, which is transmitted to the insulator to shake off the broken ice on the outside of the insulator; the force-bearing plate 6 is composed of a force-bearing plate 61 and a driving block 62. The force-bearing plate 61 is fixedly mounted on the outside of the core rod 1, and the driving block 62 is fixedly mounted on the upper end of the force-bearing plate 61; the driving block 62 is designed to be curved on one side and vertical on the other side, and the driving blocks 62 are distributed at equal angles on the upper end surface of the force-bearing plate 61; the rotating mechanism 7 includes two limiting blocks fixedly mounted on the outside of the core rod 1 The two limiting rings 71 are provided with a movable ring 72 between them, and the movable ring 72 is rotatably sleeved on the outside of the core rod 1, and the outside of the movable ring 72 is evenly installed with a scoop 73 and a vibration mechanism 74; the vibration mechanism 74 is composed of a fixed rod 741 and a movable rod 742, and the fixed rod 741 is fixedly installed on the outside of the movable ring 72, and the movable rod 742 is slidably installed inside the fixed rod 741, and a pressure spring 743 is connected between the movable rod 742 and the fixed rod 741; the lower end of the movable rod 742 is hemispherical, and the lower end of the movable rod 742 is attached to the upper end surface of the force-bearing plate 61;

When it is in a windy state, the wind scoops 73 distributed at equal angles are driven by the wind to rotate the vibration mechanism 74, that is, the movable rod 742 is driven to slide on the force-bearing plate 61. The movable rod 742 utilizes the contact effect with the driving block 62 and the elasticity of the pressure spring 743 to knock the force-bearing plate 61, and the vibration is transmitted to the insulator, so that the crushed ice on the surface of the insulator is quickly shed, the working time of the heating wire 4 is shortened, and the load of the heating wire 4 is reduced.
