Abstract: PURPOSE: A device for preventing smoke diffusion of railroad vehicle is provided to increasing the evacuating time of passenger by delaying diffusion time of smoke or toxic gas to the other cabins. CONSTITUTION: A device for preventing smoke diffusion of railroad vehicle comprises a horizontal bar(110), an incombustible screen(120), a fire sensor, and a drive motor(140). The horizontal bar is installed in the upper of an entrance(IN) of a gang way. One end of the incombustible screen is fixed to the horizontal bar. The fire sensor is arranged in the vehicle interior. The fire sensor senses smoke or gas and generates fire signals. The drive motor is installed on one end of the horizontal bar. Since the drive motor is connected to the fire sensor, the drive motor rotates a horizontal bar according to a fire signal and shields the entrance of the gang way by unrolling the incombustible screen.

Abstract translation: 目的：提供一种防止铁路车辆烟雾扩散的装置，通过将烟雾或有毒气体的扩散时间延迟到其他客舱来增加乘客的撤离时间。 构成：用于防止铁路车辆的烟雾扩散的装置包括水平杆（110），不燃性筛（120），火灾传感器和驱动马达（140）。 水平杆安装在组合方式的入口（IN）的上部。 不可燃屏幕的一端固定在水平杆上。 火灾传感器布置在车辆内部。 火灾传感器感测烟雾或气体，并产生火灾信号。 驱动电机安装在水平杆的一端。 由于驱动电机连接到火灾传感器，所以驱动电动机根据火焰信号旋转水平杆，并通过展开不燃性屏幕来屏蔽组合方式的入口。
