Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] see Figure 1-7 , an anti-snow device for power cables, including a slide rail 1, a snow removal box 2 is slidably connected to the top of the slide rail 1, and the side of the snow removal box 2 is set as an inclined slope at a certain angle, which makes snowflakes fall under their own gravity Under the action, it can slide down quickly to avoid snow accumulation. The upper part of the snow removal box 2 is provided with a metal sheet that matches the ...

The invention relates to the technical field of power cables, and discloses a snow accumulation preventing device for a power cable. The device comprises a slide rail, wherein a snow removing box is slidably connected above the slide rail, a snow accumulating bin is arranged at the upper portion of the snow removing box, the inner cavity of the snow accumulating bin is slidably connected with a movable plate, a magnet sheet is arranged at the lower end of the movable plate, an electromagnet is fixedly installed on the lower wall of the inner cavity of the snow accumulating bin, symmetrical spring supporting rods are arranged on the lower portion of the snow accumulating bin, a guide rod is arranged between the spring supporting rods, a sliding block is slidably connected to the middle of the inner cavity of the snow removing box, and elastic wedge blocks are arranged on the front portion and the rear portion of the sliding block. According to the snow accumulation preventing device forthe power cable, accumulated snow is contained in the snow accumulating bin, the guide rod falls to start the snow removing box, the elastic wedge blocks are pushed by the connecting rod, the electromagnet is started to repel the movable plate to remove accumulated snow for braking, and the effects of automatically starting snow removing according to the accumulated snow amount and stopping braking in time after one round of accumulated snow is removed are achieved.
Description
technical field [0001] The invention relates to the technical field of power cables, in particular to a snow prevention device for power cables. Background technique [0002] Due to the continuous improvement of people's living standards in our country, the development of the power industry has also been directly promoted. In the existing power industry, cables are one of the indispensable power transmission equipment, which can use cables to connect thousands of miles away Electric energy is transmitted to thousands of households, so as to achieve the purpose of power transmission. In the process of laying cables today, most of them use power towers to lay cables at high altitudes, so as to prevent electric shock damage caused by cables to the human body. In snowy weather, snow accumulates on the cables, which increases the weight of the cables, which may cause the power tower to twist and collapse. [0003] The existing anti-snow devices for power cables still have unsati...
