Subway carriage fire experiment table

Abstract

The invention relates to a subway carriage fire experiment table. The experiment table is same as a practical subway carriage in structure and is respectively provided with a door and a window at the left and the right; for the length, two ends of the experiment table are respectively provided with a front end door and a rear end door; the top inside the carriage experiment table is uniformly distributed with over three temperature probe strings inside the carriage; the upper part of the front end door is respectively provided with a temperature probe string, a speed probe string, an oxygen concentration probe and a monoxide concentration probe; one side of the exterior of the front end door is provided with a staff gauge; the middle-upper part inside the carriage experiment table is provided with an oxygen concentration probe and a monoxide concentration probe; and a camera system is arranged outside the window at one side of the experiment table. The experiment table is a large experiment table which first comprehensively and systematically researches heat release speed, smoke movement, fire detection and saving and the like of subway carriages, overcomes scale reduction and experiment error caused by a partial model experiment table, and ensures the repeatability of experiments.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to an experimental simulation device for testing the fire heat release rate, smoke flow and control system of subway train cars, and the fire detection and fighting system of train cars. Background technique [0002] In recent years, more and more subway transportation systems and their fire safety issues have aroused widespread concern. Large cities such as Beijing, Shanghai, Guangzhou, and Shenzhen in my country currently have multiple lines in operation and are continuing to be constructed. Hangzhou, Chongqing , Shenyang, Chengdu, Hefei, Harbin and other cities have also launched urban rail transit construction projects in recent years. In the fire problem of the subway transportation system, the fire in the train car and its smoke control, fire detection and fire fighting have become the focus of people's attention, because after a fire occurs in the car, the peop...

Problems solved by technology

Due to scale limitations, the above studies mostly focus on local model research, and cannot really carry out experimental research on the heat release rate and smoke flow law of the train compartment. The actual train fire test by Dowling et al. was only carried out once, which is not repeatable. , it is impossible to carry out comprehensive and systematic research. Therefore, it is a good choice to carry out a large number of full-scale experimental research and find out the existing laws. The full-scale model experimental device
