Electric heating plate, electric control box and system for melting ice in railway tunnels

Abstract

The invention discloses an electric heating plate, an electric control box and a system for melting ice in railway tunnels. The electric heating plate comprises an upper plate, a lower plate and an electric heating wire. The electric heating wire is formed in an internal cavity between the upper plate and the lower plate and is used for converting electric energy into heat energy. The electric control box comprises an outdoor temperature measuring probe and a starting temperature controller. The outdoor temperature measuring probe is used for measuring environmental temperature values of the railway tunnels; the starting temperature controller is used for setting starting temperature values, and the electric heating plate can be powered or can stop being powered when the environmental temperature values of the tunnels are lower than or higher than the starting temperature values. The system for melting the ice in the railway tunnels comprises the electric heating plate and the electric control box.

Description

technical field [0001] The invention relates to the electrical field, in particular to an electric heating plate, an electric control box and a system for melting ice in railway tunnels. Background technique [0002] Solving the phenomenon of large-scale water seepage and freezing in tunnels is a common problem worldwide. There are currently several treatment methods at home and abroad: manual ice breaking, which is mainly used in China. This method has low investment, general effect, and labor-intensive The physical resources are large, the risk factor is high, and personal safety cannot be guaranteed; the spraying of salt water to melt the ice requires a large investment, time-consuming, labor-intensive, and pollutes the environment; the hot air curtain melts the ice, which requires a large investment, complicated equipment, and a long construction period. It does not match the national conditions, and it is unreasonable to apply it to tunnel deicing. Hot water vapor is easi...
