Description
Technical field
The utility model relates to anti-icing equipment, especially a kind of electrified railway tunnel top anti-icer.
Background technology
Railway is the main artery of transportation, the safe in operation of train is most important, yet, if electrified railway tunnels top infiltration, temperature is lower than under 0 ℃ the situation in the winter time, icicle is very easily formed in infiltration, in case when there was the electric locomotive power line icicle below, icicle dropped to and can cause the tripping operation of electric locomotive power line on the electric wire, and the friction locomotive causes the accident, thereby have a strong impact on the operation conditions of locomotive operation safety and power line, therefore in order to guarantee that railway is unimpeded, must employ rail vehicle, with the artificial icicle of regularly removing, but this manual type elimination efficiency is low, the cost height, take the operating time, it is current to influence railway.
Summary of the invention
The purpose of this utility model provides a kind of deicing efficiency height, and cost is low, the electrified railway tunnel top anti-icer of safety of operation.
In order to achieve the above object, the technical solution of the utility model is: in rises, railway tunnel top the exothermic body that is made of self-temperature-limiting heating strip is installed.Described exothermic body is made of ribbon heater, fixed mount, housing, base plate, wherein by clip the ribbon heater is installed on the square tube of fixed mount, and fixed mount is installed in the housing, at the opening part of housing base plate is installed.
Ribbon heater head end in the described housing connects power lead, and the power lead at this place is installed on the housing by sealing bolt, and the end of ribbon heater is connected with indicator lamp, and an end of described indicator lamp is installed on the square tube by support, and its other end stretches out outside the housing.
Described fixed mount constitutes rectangle by the square tube arrangement in parallel more than at least, and clip is installed on square tube, is installed with the ribbon heater on clip, described ribbon heater in housing successively around forming annular shape; Fixed mount is installed in the middle part of housing, is installed on the housing around it.
It is thermal source that this programme adopts self-temperature-limiting heating strip, the ribbon heater is coiled in the metal shell, the ribbon heater energising is heated metal shell, whole exothermic body is installed in the tunnel top of icicle, as long as icicle touches housing, icicle will dissolve into water, drip on the ground, replace labor cleaning's icicle, thereby eliminate the potential safety hazard that threatens electric locomotive and power line, guarantee that railway security is unimpeded.This method is removed relatively with artificial, has the efficient height, can remove icicle at any time, and cost is low, power 280w only, little power consumption, economical, do not need to clear up car and manual operation, do not take track, and ration the power supply certainly the torrid zone temperature do not need electrical appliance control, it can be controlled voluntarily, and is safe in utilization, waterproof is good, insulate, can not form short circuit influences circuit, and it is current also not influence train, volume is little, and volume only is 600 * 300 * 30mm.

The specific embodiment
The structure of a kind of electrified railway tunnel of the utility model top anti-icer such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, mainly constitute, wherein the exothermic body that is made of self-temperature-limiting heating strip is installed in rises, railway tunnel top by ribbon heater 1, fixed mount 2, housing 3, base plate 4, sealing bolt 5, indicator lamp 6, power lead 7, support 8, clip 9, square tube 10.Described exothermic body is made of ribbon heater 1, fixed mount 2, housing 3, base plate 4, wherein by clip 9 ribbon heater 1 is installed on the square tube 10 of fixed mount 2, and fixed mount 2 is installed in the housing 3, at the opening part of housing 3 base plate 4 is installed.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known: ribbon heater 1 head end in housing 3 connects power lead 7, the power lead 7 at this place is installed on the housing 3 by sealing bolt 5, the end of ribbon heater 1 is connected with indicator lamp 6, one end of described indicator lamp 6 is installed on the fixed mount 2 by support 8, and its other end stretches out outside the housing 3.Sealing bolt 5 is M12, and indicator lamp is that φ 16, power lead are 0.7mm
2Copper core flexible cord.The connection request of ribbon heater 1, indicator lamp 6, power lead 7 is to connect with soldering earlier, wraps the layer 2-3 insulating tape again, at last with heat-shrink tube or fast dried silica gel sealing, prevents infiltration, electric leakage.
See that Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 are also as can be known: fixed mount 2 constitutes rectangle by 10 arrangement in parallels of the square tube more than at least, clip 9 is installed on square tube 10, on clip 9, be installed with ribbon heater 1, described ribbon heater 1 in housing 3 successively around forming annular shape.Fixed mount 2 is installed in the middle part of housing 3, to be installed on the housing 3 around the `, to its objective is in order allowing to remain with certain spacing between ribbon heater 1 and the base plate 4, prevented water infiltrate housing 3 interior after, avoid water to contact, the life-span of avoiding ribbon heater 1 to lose efficacy and prolonged ribbon heater 1 with ribbon heater 1.
The utility model is to install like this, and the bolt hole that passes base plate 4 two ends with bolt is installed in the rises of tunnel top with this device, because this device is the exothermic body that is made of self-temperature-limiting heating strip.The ribbon heater is coiled in the exothermic body metal shell, and the ribbon heater is heated metal shell, when tunnel top has icicle, as long as icicle touches housing, icicle will dissolve into water, drips on the ground, thereby eliminate the potential safety hazard that threatens electric locomotive and power line, guarantee that railway security is unimpeded.
