Description

Technical Field

[0001] The utility model relates to the field of intelligent snow-melting and ice-melting systems, and in particular to an intelligent snow-melting and ice-melting system for bridge structure cables. Background Art

[0002] As one of the main load-bearing components of the bridge structure, the health status of the cable during its service will directly affect the safety of the structure. In addition, with the continuous increase in operating time, the cable will also suffer varying degrees of damage under the coupling of corrosive media and fatigue loads. In recent years, with the intensification of extreme rain and snow weather in northern winter, if there is too much snow on the upper part of the cable and it is not cleared in time, as the temperature drops at night, the snow will freeze into ice, thereby increasing the load and further aggravating the damage to the cable, thus affecting the safety of the main structure and causing huge losses of life and property. The resulting incidents have occurred frequently.

[0003] In order to avoid ice and snow accumulation and damage to bridge structure cables in winter, a snow-melting and ice-removing system for bridge structures is urgently needed. At present, the snow-melting and ice-removing methods used are mostly chemical and mechanical methods, which require a large amount of labor and construction machinery, and the construction difficulty is relatively large; although the chemical method is low-cost, it will corrode the cables. To this end, the utility model combines an intelligent control module, an environmental monitoring module and a snow-melting and ice-removing module to design an intelligent snow-melting and ice-removing system for bridge structure cables.
