[0002] Ice is the general term for ice, frost, sleet and snow accumulation on overhead lines and insulator strings under certain meteorological conditions. Ice increases the vertical load of the insulator string, increases the tension of the insulator string, and then increases the windward area, all of which increase the possibility of line breakage and tower collapse. Moreover, after ice is applied, when the lower overhead line is de-iced, the sudden release of elastic energy causes the empty line to jump upward, which can cause the overhead line to dance, and then there is a safety hazard.

[0003] Common suspension strings lack corresponding de-icing structures after installation. Once the suspension strings are covered with ice or shed with ice, the safety hazards mentioned above will occur. Utility Model Content

[0008] In a preferred example, the utility model can be further configured as follows: the shield is arranged on the top of the metal frame, the shield is arranged in a bowl shape, and the bottom diameter is larger than the diameter of the grabbing plate.

[0009] In a preferred example, the utility model can be further configured as follows: the scraper is arranged in an arc shape, and both ends are bent inwards.

[0010] In a preferred example, the utility model can be further configured as follows: a plurality of scraper blades 2 are grouped in pairs, and are arranged into two groups, the two groups of scraper blades 2 are respectively located on both sides of the shield, and the two scraper blades 2 in each group are attached to both sides of scraper blade 1.

[0011] In a preferred example, the utility model can be further configured as follows: a reinforcement sleeve is connected between the scraper blade 2 and the scraper blade 3, and the reinforcement sleeve is made of alloy material.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are:

[0013] 1. In the utility model, after the main body of the suspension string is installed, once it snows, the rain and snow sensor will receive information, and then the motor will work. The motor output shaft rotates with the scraper one, and the scraper one clears the snow on the top of the shield, while also preventing the formation of ice cones on the edge of the shield. Then the scraper two and the scraper three rotate with the scraper one, and the scraper two sweeps away the ice cones at the bottom of the grab plate, and the scraper three sweeps away the ice cones at the bottom of the suspension string main body. This effectively prevents the phenomenon of ice covering, reduces the load on the main body of the suspension string, and improves safety in use.

[0014] 2. In the utility model, when the rain and snow sensor senses snow, it will automatically heat up and then heat the scraper blade 1, so that the scraper blade 1 can easily remove the snow on the top of the shield, thereby improving the snow removal ease of the device.
