Description

Technical Field

[0001] This utility model relates to a heating and drainage scheme suitable for tunnel de-icing technology, and in particular to a drainage-type heating device suitable for tunnel de-icing. Background Technology

[0002] Tunnel leakage occurs when tunnels pass through aquifers, karst fissures, or areas with abundant but shallow groundwater. Based on location and size, leakage is categorized into seepage, runoff, leakage, and runoff. In winter, when tunnel temperatures drop to around 0°C, icing often occurs at leakage points. Sometimes, the ice seals the leak, but the ice continues to develop, encroaching on the clearance and affecting train operation. Severe cases can cause short circuits in the overhead contact line, ice covering the rails, damaging rails and components, and encroaching on the clearance, posing a significant threat to train safety. To eliminate icicles from seepage points in tunnels and ensure railway power supply safety, a heating and drainage scheme suitable for tunnel de-icing technology is being researched. This scheme is specifically designed for de-icing in tunnels, providing anti-icing treatment for seepage points directly above the overhead contact line feeders and catenary cables, and diverting the melted water.

[0004] The purpose of this utility model is achieved as follows: This utility model relates to a diversion-type heating device suitable for tunnel ice melting, characterized in that: it includes: a radiant heating plate and a diversion plate; the radiant heating plate and the diversion plate are fixed together by screws, and the device is installed on the tunnel wall by fixing bolts, so that the radiant surface of the radiant heating plate faces upward or outward; the radiant heating plate has a guide hole, and the diversion plate is installed below the radiant heating plate, so that the water after the ice melts is guided to one side.

[0005] The radiant heating plate is made of carbon fiber or nickel-chromium alloy.

[0006] The drainage plate is made of stainless steel and is fixed to the bottom of the radiant heating plate with screws. The drainage plate is shaped like a sieve and has a first end opening and a second end opening. The first end opening is for water to flow through, and the second end opening is for the lead wire.

[0007] The fixing bolts are chemical bolts.

[0008] The advantages of this utility model are: it uses a radiant heating plate for the cement wall of the tunnel, which overcomes the problem of poor heating effect caused by uneven wall surface.
