Small-size multifunctional size-adjustable tunnel train two-purpose fire hazard experiment platform and experiment method thereof

Abstract

The invention relates to the technical field of fire security and in particular discloses a small-size multifunctional size-adjustable tunnel train two-purpose fire hazard experiment platform and an experiment method thereof. The experiment platform comprises a tunnel main body, an iron rack, a fire source simulation system, a ventilation system and a monitoring system, wherein the overall experiment platform is mounted and placed in a large wind tunnel; the tunnel main body comprises multiple sub-carriages of a same structure in a spliced manner; the fire source simulation system comprises porous gas combustors, a gas flowmeter, a fuel gas vessel and a gas supply tube; the porous gas combustors are mounted at combustion openings in the bottoms of the sub-carriages; the ventilation systemcomprises an external wind tunnel as well as a small variable-frequency fan and a rectification tube section which are connected with a model; the monitoring system comprises a temperature testing system, a flue gas flowing testing system, a digital camera recording system and a computer connected with the digital camera recording system.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a small-sized, multi-functional and size-adjustable dual-purpose fire experiment platform for tunnel trains and an experiment method thereof. Background technique [0002] The subway is the result of the progress of our times. From the middle of the twentieth century to the present, our world has been undergoing tremendous changes and progress all the time, followed by explosive population growth and continuous urbanization. In the process of these changes, people's means of transportation have undergone a series of changes such as horse-drawn carriages, bicycles, and automobiles. The speed of urban planning is gradually unable to keep up with people's growing travel needs. At this time, various urban congestion phenomena have been brought. At the same time, in the process of social development, people face various problems such as energy crisis and environmental pollution....
