Embodiment 1

[0018] Such as Figure 1-2 As shown, a safe and energy-saving anti-snow device for overhead cables includes a plurality of snow removal parts sleeved outside the cables. The side walls of the body 1 away from each other are fixedly connected with permanent magnet blocks 2, and the multiple permanent magnet blocks 2 are all repelled by the same pole. The cable is provided with a spiral brush strip 3 formed by spirally curling long stainless steel shrapnel. The spiral brush strip 3 is attached on the surface of the cable, and the two ends of the spiral brush strip 3 are respectively fixedly connected with two annular shells 1, and the inner walls of the two annular shells 1 are fixedly connected with electromagnets 4, and the electromagnetic The iron 4 is made of silicon steel material. The two electromagnets 4 are wound with an induction coil 5. The winding directions of the two induction coils 5 are opposite. The non-contact discharge needles 6 and the two ends of the inducti...

Embodiment 2

[0021] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 lies in that: a whistle 7 is fixedly installed on the side wall of the annular housing 1 , and a resonant rod 8 is fixedly installed on the inner wall of the annular housing 1 .

[0022] In this embodiment, the wind in the sky blows the whistle tube 7 to make a sound, and the vibration caused drives the resonant rod 8 to vibrate. Because the inner seal of the annular shell 1 forms a resonant cavity, the vibration of the resonant rod 8 can last for a long time , Then cause the cable to vibrate, shake off the snow, and play the role of assisting snow removal.

Embodiment 3

[0024] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a horizontally arranged wing plate 9 is provided below the annular housing 1, and a horizontally arranged lifting plate 10 is slidably connected to the inner side wall of the annular housing 1. The plate 10 is fixedly connected to the wing plate 9 through the connecting rod, one of the discharge needles 6 is fixedly installed on the upper top surface of the annular housing 1, and the other discharge needle 6 is fixedly installed on the upper surface of the lifting plate 10, and the wing plate 9 is set Below the annular housing 1, the snow accumulation on the wing plate 9 can be reduced. At the same time, when the annular housing 1 moves, the wing plate 9 can be moved to shake off the snow on the wing plate 9 to ensure that the wing plate 9 can be used in snowy weather. normal work.

[0025] In this embodiment, when there is no wind and no snow, the distance between the two disch...

Abstract

The invention belongs to the field of electric power accessories, and in particular relates to a safe and energy-saving anti-snow device for overhead cables, which includes a plurality of snow removal parts sleeved outside the cables, and the snow removal parts include two sleeves sleeved outside the cables. An annular housing, permanent magnet blocks are fixedly connected to the side walls of the two annular housings away from each other, and the plurality of permanent magnet blocks repel each other with the same pole. A spiral brush strip formed by spirally curling stainless steel shrapnel. The spiral brush strip is attached to the surface of the cable. The two ends of the spiral brush strip are respectively fixedly connected with two annular shells. Electromagnets are fixedly connected to the inner walls, and induction coils are wound around the two electromagnets, and the winding directions of the two induction coils are opposite. The invention can repeatedly stretch and compress the spiral brush bar to scrape and wash the power line repeatedly, and can effectively and thoroughly remove snow accumulation.

Description

technical field [0001] The invention belongs to the field of electric power accessories, in particular to a safe and energy-saving anti-snow device for overhead cables. Background technique [0002] The overhead cable is a special form of transmission line that is supported by poles and erected in the mid-air above the driving track of the electric drive vehicle, and is used to directly supply power to it when it is in contact with it. [0003] In the winter of the overhead cable, snow often occurs on the upper part of the wire. If the amount of snow is large, it is likely to break the wire, cause the grid failure, and cause the dropped cable to cause a greater safety hazard. The cable is erected at a high position, and it is difficult to remove snow manually. In the existing technology, most of the snow removal methods are dedicated snow removal robots, electric heating or electromagnetic oscillation. These methods will consume the electric energy in the cable in actual use...
