Railway turnout ground electric heating ice and snow melting system
The invention discloses a railway turnout ground electric heating ice and snow melting system which comprises a power source and a control cabinet and further comprises a plurality of heating devices and an ice and snow detector, and the heating devices are pre-buried in a track base below a turnout rail so that the track base can upwards form a heat radiation temperature field with the hot lower portion and the cold upper portion to the top end of the rail; the ice and snow detector is installed on a mechanical movable part of a turnout. The system has the advantages that the U-shaped heating cable in the track base below the rail forms the temperature field which is hot at the lower part and cold at the upper part from the track base to the top end of the rail upwards, the temperature field is like a sandwich, the system automatically monitors climate change through the ice and snow detector, when snow and ice are accumulated, the temperature of the turnout iron piece is always kept above +2 DEG C, and snow accumulation and icing are prevented at the turnout. And the melted snow water can naturally permeate and run off due to the heat accumulated in the roadbed layer, so that secondary icing cannot be caused.
本发明公开了一种铁路道岔地电热融冰雪系统，包括电源和控制柜，还包括若干加热装置和冰雪探测器，所述加热装置预埋于道岔铁轨下方的道基内，以使道基向上至铁轨顶端形成下热上冷的热辐射温度场，所述冰雪探测器安装于道岔的机械活动部。本发明的有益效果在于：铁轨下方的道基内的U形加热电缆，从道基向上至铁轨顶端形成下热上冷的温度场，“像一个三明治”，该系统通过冰雪探测器自动监测气候变化，有积雪结冰条件产生时，始终将道岔铁件的温度保持在+2℃以上。使得道岔不能积雪结冰，融化的雪水由于道基层所积蓄的热量将自然渗透流失，不会造成二次结冰。
