Modular longitudinal smoke exhaust subway tunnel moving body fire experiment system

Abstract

The invention discloses a modular subway tunnel moving body fire scaling-down experiment system. The system comprises a tunnel body, a pressure testing system, a temperature testing system, a smoke analysis system, a piston wind speed testing system, a train model and a burner arranged in the train model, wherein the pressure testing system, the temperature testing system, the smoke analysis system and the piston wind speed testing system are arranged on the tunnel body. The tunnel body and the train model are both formed by splicing multiple scaling-down model experiment standard sections. A locomotive and the tail of the train model are connected with a train model moving driving system and a train model moving driven system through chains respectively, and a jet fan air valve, a scaling-down jet fan, a smoke shaft axial flow fan and a smoke shaft air valve are arranged on the outer tops of the standard sections of the tunnel body. The length of a model tunnel is adjusted by adjusting the number of the standard sections of the tunnel body, and subway or railway tunnel moving body fire characteristics, smoke diffusion characteristics and the piston wind rule of a smoke exhaust scheme are researched by adjusting the starting combination mode of a jet fan module and a shaft axial flow fan module.

Description

technical field [0001] The invention relates to a size reduction experiment system for multi-moving body fires in long and long subway tunnels, in particular to a modularized longitudinal smoke exhaust subway tunnel moving body fire experiment system. Background technique [0002] In recent years, as my country's high-speed rail and subway technologies have matured, the scale of tunnels under construction and newly put into use has also increased year by year. According to statistics, the frequency of tunnel fires is about 2 times per 108 vehicles per kilometer. The impact of the fire and the threat to the safety of the personnel tunnel structure are enormous. With the growth of subway tunnels, trains are often forced to slow down until they stop after a fire, and finally stay in the tunnel for emergency evacuation. This is caused by the following three situations: 1) The driving system is usually cut off when a fire occurs 2) The failure of the driving motor will also cause...
