The invention discloses an urban rail transit train carriage fire high-temperature alarm system, which relates to the technical field of fire alarm, and comprises a monitoring cylinder, a movable assembly, a temperature sensor, a temperature sensor and a temperature sensor, a separation cavity is fixedly installed in the circulation shell through a supporting flow guide plate, and a spiral plate is arranged on the inner wall of the separation cavity in a matched mode. By arranging the monitoring cylinder capable of swinging in two directions, when an ignition point is far away from a mounting position, a high-temperature fire early warning can be given out, high-pressure water mist can be sprayed to extinguish fire and cool a carriage, and further expansion of the fire is inhibited; smog is separated from air, so that the smog concentration at the smog sensor is improved, and the detection sensitivity is further improved; two detection modes are set, so that the high temperature in the distance and the smoke in the distance can be detected.
本发明公开了一种城市轨道交通列车车厢火灾高温报警系统,涉及消防报警技术领域,包括监测筒,监测筒内配设有透镜和光电传感器,光电传感器安装在透镜的焦点位置,还包括活动组件,所述活动组件包括循环壳,循环壳内通过支撑导流板固定安装有分离腔,分离腔的内壁上配设有螺旋板。本发明通过设置可以两个方向摆动的监测筒,当着火点发生在距离安装位置较远时,可以发出高温火灾预警,喷射高压细水雾对其车厢进行灭火降温,抑制火灾的进一步扩展;通过将烟雾与空气分离,提高烟雾传感器处的烟雾浓度,进一步的提升了检测的灵敏度;通过设置两种检测方式,既可以检测远处的高温也可以检测近处的烟雾。
