Description

TECHNICAL FIELD

[0002] Cables, as the key carriers of power transmission and information delivery, play an indispensable role in modern society. Structurally, it is mainly composed of a conductor, an insulating layer, and a protective layer. The conductor, usually made of highly conductive copper or aluminum, is responsible for the conduction of electric current, ensuring stable power transmission. The insulating layer, wrapped around the conductor, is made of materials such as rubber and plastic with good insulating properties, effectively preventing current leakage and ensuring electrical safety. The outermost protective layer, generally composed of metal armor or tough plastic, can resist mechanical damage, chemical corrosion, and moisture intrusion from the outside environment.

[0003] If the snow on the surface of the cable is not removed in time during snowy weather, it will affect the normal work of the cable. Snow can absorb moisture in the air, reducing the insulation performance of the cable, possibly leading to current leakage, causing short circuit failure, interrupting power transmission, affecting residential life and industrial production electricity, causing economic losses. At the same time, a large amount of snow accumulation on the cable will increase the weight of the cable, especially in mountainous or complex terrain areas, the cable may be pulled apart due to the heavy load, or cause the power pole to tilt and collapse, not only increasing the difficulty and cost of maintenance, but also posing a threat to the surrounding environment and personnel safety.

By arranging the connecting frame 99 and the extrusion frame 910, when the rotating ring 91 moves horizontally, the extrusion frame 910 extrudes the wave plate 719. Due to the blocking of the groove of the wave plate 719, and the fact that the groove is rounded, the wave plate 719 will move downward, thereby moving the sliding frame 714 downward.

[0042] Working principle: in use, the operator positions the device at the lowest point of the cable sag to deal with the impact of the snow at the bottom end, when it snows, the snowflakes will fall on the outer surface of the triangular plate 715 and the outer protective layer 1, under the guidance of the triangular plate 715, the snowflakes flow to the upper surface of the inclined plate 77 and fall into the inner cavity of the collection box 841, and part of the snowflakes will adhere to the upper surface of the inclined plate 77 due to friction, after the snow accumulates too much, the balance of the inclined plate 77 is broken, which makes the rotating column 73 rotate in the inner cavity of the limiting ring 72, and finally the snow on the outer surface of the inclined plate 77 falls into the inner cavity of the collection box 841, and then under the influence of the gravity of the snow, the collection box 841 slides down due to the sliding of the sliding sleeve 82 on the outer surface of the track rod 81, in the process, the telescopic pipe 94 pulls the rotating ring 91 to move laterally, under the limitation of the screw ring 10, the rotating ring 91 rotates, which makes the fan plate 97 and the rubber brush 98 rotate and scrape the snow on the outer surface of the outer protective layer 1;

[0043] At the same time, the extrusion frame 910 moves laterally with the rotating ring 91, which makes the extrusion frame 910 extrude the wave plate 719, due to the barrier of the groove of the wave plate 719, and the roundness of the groove, the wave plate 719 moves downward, which makes the sliding frame 714 move downward, in the process of the sliding frame 714 moving downward, the extrusion cover 717 strikes the ice layer attached to the outer surface of the outer protective layer 1, and under the action of the semicircular rod 7112 and the third spring 7113, the extrusion cover 717 constantly strikes the outer protective layer 1, which finally makes the frozen ice layer be removed;

[0044] In the process of the collection box 841 continuously sliding down, the extrusion rod 89 pushes the material pushing plate 843, which makes the snow in the inner cavity of the collection box 841 be pushed out and discharged from the hole, at this time, the collection box 841 is no longer affected by the gravity of the snow, and under the influence of the elastic potential energy of the fourth spring 86, it rebounds, at this time, the telescopic pipe 94 is compressed, which makes the air inside be sprayed out from the air jet pipe 812, achieving the effect of cleaning the residual snow on the fan plate 97 and the outer surface of the outer protective layer 1.
