Fire experiment device based on city underground comprehensive pipe rack

Abstract

The present invention discloses a fire experiment device based on a city underground comprehensive pipe rack. The pipe rack comprises a left side pipe rack and a right side pipe rack; a water supply pipeline is arranged on the ground of the left side pipe rack through a pipeline support; a high electric cable and a weak electric cable are respectively arranged at two sides of the left side pipe rack through an insulation support; a camera and an illumination lamp are installed at the top of the left side pipe rack; a drainage ditch is arranged at the bottom of the left side pipe rack; a gas pipeline is arranged on the ground of the right side pipe rack through the pipeline support; a camera and an illumination lamp are installed at the top of the right side pipe rack; and a drainage ditch is arranged at the bottom of the right side pipe rack. The fire experiment device comprises a transverse ventilation control system, a simulation fire source system, a fire detection system, a water mist fire extinguishing system and a water spray fire extinguishing system. The fire experiment device based on a city underground comprehensive pipe rack can simulate the city underground comprehensive pipe rack fire experiment so as to provide scientific reference for underground comprehensive pipe rack control and optimization, power-on electric wire propagating, fire detection and fire extinguishing.

Description

technical field [0001] The invention relates to the fire safety field of urban underground comprehensive pipe gallery, in particular to a fire experiment device for urban underground comprehensive pipe gallery. Background technique [0002] The urban underground comprehensive pipe gallery is a tunnel space built underground in the city, which integrates various engineering pipelines such as power, communication, gas, heating, water supply and drainage, and is equipped with special inspection ports, hoisting ports and monitoring systems. Unified planning, unified design, unified construction and management are the important infrastructure and "lifeline" to ensure the operation of the city. The research on smoke control, fire detection and fire extinguishing control of urban underground comprehensive pipe gallery is imminent. Through simulation experiments, the study of smoke spread and control law in urban underground comprehensive pipe gallery under fire conditions is used t...

AI Technical Summary

Problems solved by technology

[0004] Through the investigation and analysis of the existing technology, it can be seen that the existing conventional tunnel fire experiment equipment cannot represent the urban underground comprehensive pipe gallery in terms of structure and function. At present, there are few studies on the fire combustion test of the urban underground comprehensive pipe gallery. There is no relevant specialized experimental research platform, and scientists still lack relevant understanding

If the fire cannot be reasonably detected and controlled, it will cause a lot of waste of resources
