Example Embodiment

[0050] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0051] The station hall floor module 1 is located on the uppermost layer of the model, and the passenger escape port 6 is located on the ceiling of the station hall floor model to communicate with the outside world. The station hall layer module 1, the line A platform layer module 2, and the line B platform layer module 3 are connected by a connecting two-way escalator opening 9 and its supporting bolts. After the main body of the model is assembled, it is placed on the model support 4. The train track area 7 of the platform layer module 2 of line A is located in the middle of the module, and the passenger waiting area 8 is located on both sides of the module; the passenger waiting area 8 of the platform layer module 3 of line B is located in the middle of the module, and the train track area 7 is located on both sides of the module. The fresh air duct 10 and ...

Abstract

The invention discloses a combined type smoke spreading research model apparatus for a fire hazard in a subway transfer station. A station hall layer module is positioned on the uppermost layer of the model, the station hall layer module and line platform layer modules are connected through bidirectional stair or elevator ports for connection, a ventilation smoke evacuation system is installed on the ceiling of the platform layer modules, and the tail ends of air ducts are provided with an air quantity regulators and connected with blower fans. Fire source/ hot smoke generating devices are arranged on the platform layer modules. Under a fire source condition, a fuel plate is placed in a fireproof base plate and sent into the model. Under a hot smoke condition, a cake tobacco burns in a smoke generating furnace, the fuel plate is heated under the smoke generating furnace, and smoke enters into a smoke generation air channel and sent to the model through smoke collecting fan housing. The combined type smoke spreading research model apparatus is built in a modularized way, is simple in structure, flexible and convenient in dismounting and assembly, and can simulate subway platforms with different structures. Multiple fire sources condition in a station can be simulated, and fire safety performance assessment and analysis for large subway transfer stations can be performed.

Description

technical field [0001] The invention designs a fire experimental research device, in particular relates to an experimental device of a subway transfer station model with a combination system of multiple working conditions for fire smoke diffusion research, and belongs to the technical field of subway safety experiments. Background technique [0002] The subway has the characteristics of large passenger capacity, fast, safe, punctual, and comfortable operation, low operating costs, low environmental pollution, and high comprehensive economic efficiency. It is an effective way to solve problems such as urban road traffic congestion and residents' difficulty in traveling. Fires in subway stations are the most harmful part of urban traffic disasters. Due to the closed environment of the subway station and the difficulty of escape and rescue, once a fire breaks out in the station, it often causes serious casualties, huge social impact and economic losses. Smoke is the main facto...
