Problems solved by technology
[0004] The high-altitude power line is the basic power facility for remote power transmission; during the power transmission process, it needs to withstand the climate test of various regions, for example, in some cold mountainous areas, the high altitude where the transmission line is located has extremely cold temperatures and often encounters rain Weather, at this time, the surface of the transmission line is very easy to accumulate snow and ice, resulting in a sharp increase in the weight of the transmission line, and then the power line is likely to break and fall when the wind blows
The current high-altitude power lines are made of twisted steel wires, which basically face this kind of problem, causing great trouble to the power construction department

Embodiment Construction
[0018] Below in conjunction with accompanying drawing and embodiment the present invention is further described:
[0019] Such as figure 1 As shown, the high-altitude power line ice scraper includes a non-rotating body 21; the non-rotating body 21 is sleeved on the outer periphery of the power line 1, and the shaft hole that the non-rotating body 21 matches with the power line has a smooth surface; the non-rotating body 21 can slide linearly along the transmission line 1; the two ends of the non-rotating body 21 are symmetrically matched with a pair of rotating bodies 22 and 23 that are also sleeved on the outer periphery of the power line 1; the rotating body and the non-rotating body pass through the annular chute Cooperate so that the rotating bodies 22 and 23 can freely rotate around the axis of the non-rotating body 21 , that is, the axis of the transmission line 1 .
[0020] An example of the rotating body 22, 23 is figure 2 As shown, the surface of the shaft hole 220...

The invention provides a high altitude power transmission line ice scraper. The high altitude power transmission line ice scraper comprises a non-rotation body which sleeves the periphery of a power transmission line and slides along the power transmission line in straight line mode, wherein a pair of rotation bodies symmetrically arranged at two ends of the non-rotation body in matching mode sleeves the periphery of the power transmission line, the rotation bodies freely rotate around the axis of the non-rotation body, a spiral matched with a twisted thread of the power transmission line is formed on the surface of an axle hole in each rotation body, used to sleeve the power transmission line, a weight ratio between the non-rotation body and each rotation body is larger than 10:1, each rotation body comprises a metal end face which directly faces the end of the non-rotation body, the non-rotation body comprises an induction power source and an electromagnet array, which surround the power transmission line, a remote switch and an oscillating circuit are sequentially connected with the induction power source and the electromagnet array, the electromagnet array comprises more than two electromagnets which are evenly distributed along the circumference of the electromagnet array, and the oscillating circuit enables all the electromagnets in the electromagnet array to conduct in turn according to a set clock direction. The high altitude power transmission line ice scraper can easily remove ice and snow under the condition that the snow or the ice is accumulated on the surface of the power transmission line, and thereby prevents the power transmission line from fracturing.
Description
[0001] technical field [0002] The invention relates to the field of electric power facilities, in particular to an ice scraper for high-altitude transmission lines. [0003] Background technique [0004] The high-altitude power line is the basic power facility for remote power transmission; during the power transmission process, it needs to withstand the climate test of various regions, for example, in some cold mountainous areas, the high altitude where the transmission line is located has extremely cold temperatures and often encounters rain Weather, at this time, the surface of the transmission line is very easy to accumulate snow and ice, resulting in a sharp increase in the weight of the transmission line, and then the power line is likely to break and fall when the wind blows. The current high-altitude power lines are twisted by steel wires, and basically all face this problem, which causes great troubles for the electric power construction department. [0005] C...
