Railway tunnel deicing device
The invention discloses a railway tunnel deicing device. The railway tunnel deicing device comprises an ice melting cornice, a first ceramic electric heating pipe, a first temperature control switch, a support frame, an aluminum alloy cover plate, a fastening clamp, a second ceramic electric heating pipe, an aluminum alloy downpipe, a draining blind ditch, a switch, a wire, a ceramic glaze layer, a ceramic layer, electric heating wires, a cornice longitudinal slope, a U-shaped sleeve and a second temperature control switch. The temperature at the top of a tunnel can be kept between 10DEG C and 30DEG C, so that water leaking from the top of the tunnel cannot ice but directly drop on the cover plate at the lower part. Then, water flows into the downpipe along the ice melting cornice. Finally, water flows into the underground draining blind ditch. The ceramic electric heating pipes, formed by using ceramic as a base body and winding the electric heating wires in series, are high in electric heating conversion efficiency, rapidly rise the temperature, are low in thermal inertia, resistant to high temperature, resistant to corrosion, great in thermalchemical performance stability, long in service life, high in insulating strength and free of pollution, and can save energy by 30% more or less in comparison with other electric heating elements. The production of ice streams can be radically prevented.
