FIRE SIMULATION EXPERIMENT PLATFORM FOR UNDERGROUND TRAFFIC CONVERSION PASSAGE

摘要

Disclosed is a fire simulation experiment platform for an underground traffic conversion passage. The platform comprises a model body (1) for simulating an underground traffic conversion passage, a combustor (2) abutting against the model body (1) and generating smoke, and a smoke imaging system, wherein the smoke imaging system comprises laser sheet light sources (31) and image recording devices (32) for recording smoke distribution images; there are multiple laser sheet light sources (31) arranged inside the model body (1), and a planar laser emitted by the laser sheet light sources (31) is parallel to a flow direction of the smoke; there are multiple image recording devices (32) that correspond to the laser sheet light sources (31) on a one-to-one basis, and are arranged outside an observation window of the model body (1); and one laser sheet light source (31) and one image recording device (32) in a pair, correspond to one another, are respectively provided with a light filter (33) for filtering lasers of the same wavelength. The fire simulation experiment platform for an underground traffic conversion passage can facilitate research on a horizontal spreading feature of the smoke, and is particularly suitable for simulating a fire in the underground traffic conversion passage.
