Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a cable with a snow accumulation prevention device. Background Art

[0002] As a key carrier for power transmission and information transfer, cables play an indispensable role in modern society. Structurally, they are mainly composed of conductors, insulation layers, and protective layers. Conductors are usually made of highly conductive copper or aluminum materials, which are responsible for the conduction of current and ensure stable power transmission. The insulation layer is wrapped around the conductor and is mostly made of materials with good insulation properties such as rubber and plastic to effectively prevent current leakage and ensure electricity safety. The outermost protective layer is generally made of metal armor or tough plastic, which can resist external mechanical damage, chemical corrosion, and erosion from humid environments.

[0003] If the snow on the outer surface of the cable is not cleared in time during snowy weather, it will affect the normal operation of the cable. The accumulated snow will absorb moisture in the air, reduce the insulation performance of the cable, which may cause current leakage, trigger short circuit failure, and interrupt power transmission, affecting residents' lives and industrial production electricity consumption, causing economic losses. At the same time, a large amount of snow accumulated on the cable will increase the load on the cable, especially in mountainous areas or areas with complex terrain. The cable may be broken due to being overloaded, or cause the poles to tilt or collapse, which is not only difficult and costly to repair, but also poses a threat to the surrounding environment and personnel safety.

The extrusion frame 910 is extruded and adapted to the surface of the wave plate 719. By setting the connecting frame 99 and the extrusion frame 910, the extrusion frame 910 can extrude the wave plate 719 when the rotating ring 91 moves horizontally. Due to the obstruction of the groove of the wave plate 719 and the rounded groove, the wave plate 719 will move downward, thereby causing the sliding frame 714 to move downward.

[0042] Working principle: When in use, the operator positions the device at the lowest point of the cable droop to deal with the impact of snow accumulation at the bottom end on the cable. When it snows, 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 along with the guidance of the inclined plate 77. Some snowflakes will adhere to the upper surface of the inclined plate 77 due to friction. After too much snowflakes accumulate, the balance of the inclined plate 77 is broken. , and then the rotating column 73 rotates in the inner cavity of the limiting ring 72, and finally the snowflakes on the outer surface of the inclined plate 77 fall into the inner cavity of the collecting box 841. Then, under the influence of the gravity of the accumulated snow, the collecting box 841 slides downward because the sliding sleeve 82 slides on the outer surface of the track rod 81. During this process, the telescopic tube 94 pulls the rotating ring 91 to move horizontally. Under the limitation of the threaded ring 10, the rotating ring 91 rotates, and then the fan plate 97 and the rubber brush 98 rotate, and the snow on the outer surface of the outer protective layer 1 is scraped off;

[0043] At the same time, the extrusion frame 910 moves laterally together with the rotating ring 91, so that the extrusion frame 910 squeezes the wave plate 719. Due to the obstruction of the groove of the wave plate 719, and the groove is round, the wave plate 719 will move downward, thereby causing the sliding frame 714 to move downward. When the sliding frame 714 moves downward, the extrusion cover 717 will strike 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 continuously strikes the outer protective layer 1, and finally the frozen ice layer can be removed;

[0044] As the collection box 841 continues to slide down, the extrusion rod 89 will push the push plate 843, thereby pushing out the snow in the inner cavity of the collection box 841 and discharging it 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 tube 94 is compressed, so that the internal air is ejected from the jet pipe 812, thereby achieving the effect of cleaning the residual snow on the outer surface of the fan plate 97 and the outer protective layer 1.
