Radiant railway switch de-icing/snow removing system

Abstract

The invention relates to a railway switch anti-ice / snow solution for automatically melting down ice and snow at the closely jointed parts of a switch. A radiant railway switch de-icing / snow removing system comprises an intelligent power source, an intelligent controller and a radiator, wherein the intelligent power source is connected to the radiator through the intelligent controller and a buried cable; the radiator is arranged inside after a switch stock rail and a point rail are closed up; the radiator is fastened to the rail web of the switch stock rail by means of a clamp; and the radiator is started according to an instruction to directly melt down accumulated snow at the closely jointed parts of the switch by means of the infrared radiation heating technology. The device of the system is simple and convenient to mount without interference with any other railway electrical system; the working time is short; heat energy conversion and de-icing and snow removal efficiencies are high; and in the working process, reliable de-icing and snow removal at the closely jointed parts of the switch can be ensured; therefore, turn-out and locking of the switch in place are ensured and railway transportation is normal.

Description

technical field [0001] The patent of the invention belongs to a supporting device for railway transportation facilities, and relates to a snow-melting device for a railway turnout with the functions of automatically melting ice and snow at the position of the railway turnout, ensuring the normal switching of the turnout, and the signal chaining in place. Background technique [0002] In most parts of our country, the railway transportation system is often plagued by ice and snow in winter. How to timely, safely, economically and reliably remove the snow from the railway turnout and prevent the failure of the turnout device has always been a key issue in railway transportation. It is a problem that the transportation system attaches great importance to but is difficult to solve. The electric heating turnout snow melting system currently in use conducts heat to the basic rail, sliding bed plate and tip rail through the heating device installed next to the basic rail of the tur...

AI Technical Summary

Problems solved by technology

However, because the mass of the basic rails, sliding bed boards and point rails is relatively large, the heat dissipation surface is also large, and the energy consumed for heating them is also large, which is also greatly affected by the low external temperature and wind speed. It is necessary to melt snow at night when the temperature drops. Uses more energy and is less efficient, and when snowmelt is done at night, it can sometimes refreeze during the coldest hours of dawn, which can adversely affect turnouts

In this way, when encountering a large snowstorm or freezing weather, the snow melting system will fail, which will affect the normal operation of the switch machine, the turnout cannot be locked, and the locomotive cannot pass, causing delays and outages in railway transportation.
