Description

Technical Field

[0001] The invention belongs to the technical field of cable deicing, and in particular relates to a high-speed railway cable crushing-cleaning integrated deicing device. Background Art

[0002] With the rapid development of high-speed railways, high-speed railways, as an important means of transportation, play a vital role in daily life and economic activities. However, the accumulation of ice and snow in cold winter weather poses a serious threat to the safe operation of high-speed railways, especially the ice and snow cover and freezing on key facilities such as overhead cables, which not only increase the weight of the cables and affect their power transmission efficiency, but also may cause the cables to break or wear, thereby endangering the normal operation of trains. Especially in some high-altitude cold areas, due to low temperature and high humidity, thick ice layers are easily formed on cables, making de-icing a technical problem that cannot be ignored.

[0003] Existing deicing methods for high-speed railway cables are mainly divided into manual deicing and automatic deicing. Manual deicing usually requires professionals to climb or use equipment to clean the ice on the cables, which has problems such as low work efficiency, great safety hazards, and high labor costs. Due to the special structure of high-speed railway cables, the automatic deicing technology for high-speed railway cables is not as mature as that for ordinary cables. In addition, some heating deicing equipment is difficult to maintain a stable heating effect in long-term operation, and the deicing efficiency is insufficient in extremely low temperature environments.

[0004] Therefore, how to design an efficient, safe and energy-saving high-speed railway cable crushing-cleaning integrated deicing device to cope with various complex climatic conditions and ensure the safe operation of high-speed railway lines has become a technical problem that needs to be solved urgently.
