Aerial cable deicer

Abstract

The invention discloses an aerial cable deicer. The aerial cable deicer is characterized by comprising a first rack, a second rack, a third rack and a fourth rack, wherein each rack is formed by an upper beam, a lower beam and two side beams which are respectively connected with the upper beam and the lower beam, the upper end and lower end of one side beam are respectively connected with the upper beam and the lower beam, the lower end of the other side beam is connected with the lower beam, a notch is formed between the upper end of the other side beam and the upper beam, a crawling mechanism is arranged inside the upper beam, the crawling mechanism is fitted inside the racks and is internally provided with a fixed clamping mechanism, the lower beams of the first rack, the second rack, the third rack and the fourth rack are connected with a travelling transmission mechanism, and the outer end of the first rack is connected with a deicing mechanism. The aerial cable deicer disclosed by the invention has the advantages of higher deicing efficiency, better safety and high adaptability and is simple to control.

Description

technical field [0001] The invention relates to a deicing device, in particular to a deicing device for high-altitude cables. Background technique [0002] In most parts of northern my country, there will be a lot of snowfall every year in the cold winter, resulting in the formation of ice layers and icicles around the cables of high-voltage transmission lines. As a result, many cables have been seriously damaged, causing greater economic losses to the country, and directly affecting the lives of the people. At the same time, the falling ice will also bring danger to passers-by. Therefore, it is very important to remove the ice layer and icicles on the high-altitude cables in time. [0003] At present, deicing on cables mainly uses mechanical external force to force the ice coating on cables to fall off manually or automatically. Typical mechanical de-icing methods are "ad hoc", vigorous vibration, and pulley scraping. The "ad hoc" method is operated by the staff on site, ...

AI Technical Summary

Problems solved by technology

The "ad hoc" method is operated by the staff on site, and the treatment method depends on the actual situation. When the ice coating on the cable is easy to fall off, manual deicing is used; when the ice coating is difficult to fall off, helicopters or Deicing firearms, this method of deicing is neither safe nor effective

The strong vibration method is a deicing method that vibrates the ice-coated cable within a controllable range through vibration. This method has a certain effect on deicing rime, but the deicing effect on rime is not good.

The pulley scraping method is a method in which ground operators control the operation of a pulley walking on the cable to remove ice from the cable. The pulley scraping method does not require special equipment and professionals, and is easy to operate and consumes less energy. This method is time-consuming and limited by the geographical environment

In addition, the mechanical deicing method has disadvantages such as low efficiency and imperfect safety performance, so it is relatively seldom used in my country.
