Intelligent railway tunnel ice melting device

Abstract

The invention provides an intelligent railway tunnel ice melting device, which aims to solve the problem of icing caused by water seepage in railway tunnels in winter, and prevents the line accidents such as shortened insulation distance between a contact network and a tunnel wall, frequent tripping in substations and burnt cables of the contact network and the like caused by the problem of icing. The intelligent railway tunnel ice melting device consists of an electric control cabinet and an electric heating plate and is mainly applied to deicing the tunnel wall. According to the intelligent railway tunnel ice melting device, electrical energy is directly converted into heat energy through the electrical heating plate, heat is uniformly spread at water seeping positions on the tunnel wall in a manner of high-temperature radiation, seeping water is heated and drops down along the plate surface in the form of liquid water, and icing cannot be formed. The intelligent railway tunnel ice melting device realizes an intelligent self-starting temperature-control deicing function. The intelligent railway tunnel ice melting device has the characteristics of small volume, high thermal efficiency, quick and firm assembly, convenience for operation and the like; the electric control cabinet can control 1 to 5 groups of electric heating plates; and users can freely select the using quantity of the electric heating plates according to the sizes of water seeping gaps, so that the intelligent railway tunnel ice melting device is flexibly used, is convenient to match and can be widely applied to the field of ice melting of the electrified railway tunnels.

Description

technical field [0001] The invention relates to an intelligent railway tunnel ice melting device. Background technique [0002] The accumulation of new and old tunnels will inevitably lead to tiny cracks, resulting in water seepage, water leakage, and water leakage. There are about 50,000 railway tunnels in China, among which there are different degrees of water gushing, water leakage, water leakage, dripping, water seepage, and wet water during operation. It accounts for about 1 / 3 of the total number of tunnels in the whole road. In the winter climate, when the seepage water seeps to the tunnel wall, due to the cold climate and the cold wind brought by the passing train, the seepage water will soon freeze, causing ice to hang on the tunnel wall. Icicles will be formed in severe winter areas, and the icicles will gradually lengthen and get closer to the catenary, which will shorten the insulation distance between the catenary and the tunnel wall, causing electric arcs to be...
