A fire safety research model device for a combined underground utility gallery space

Abstract

The invention is a combined underground pipeline space fire safety research model device. The device is composed of a plurality of detachable and assembled comprehensive pipe gallery modules with the same structure. The combination module includes frequency conversion ventilation device, fire source device, slope adjustment device, fire detection device and fire fighting system. One end of the main corridor is fixed on the support frame, and the other end is supported by a jack, which can adjust its slope. A mobile trolley equipped with a combustion oil pan and a cable rack can slide in the pipe gallery to change the location of the fire source. Each pipe gallery module can be freely disassembled and assembled. The combined modules can also be combined to form multi-layer or multi-cabin pipe corridors. After the fire detection device gives an early warning, the corresponding fire extinguishing medium, such as water or gas, can be provided for fires with different fire source powers through the control of the fire protection system. This device provides a comprehensive, convenient and flexible scale experimental model of small-scale comprehensive pipe gallery, which can make any combination of different pipe gallery structures, fire protection systems, fire detection devices, ventilation modes, fire source types, and pipe gallery slopes to meet the needs of experimenters. The need to carry out simulation experiments on fire conditions of various complex pipe galleries.

Description

technical field [0001] The invention relates to a combined underground pipeline space fire safety research model device. A plurality of underground pipe space experimental device modules with simple structures and different sizes that can be disassembled and assembled are designed, and are connected to each other through groove combinations. Inside, slots are reserved for replaceable facilities such as fire protection systems, fire detection devices, ventilation devices, and fire sources, so as to realize combined experiments under various working conditions in the underground pipeline space, especially in the comprehensive pipeline gallery space. Background technique [0002] The urban comprehensive utility corridor specifically refers to a tunnel structure in which two or more types of municipal pipelines on the ground, underground or overhead are collectively arranged in the same underground artificial space, and a passage for maintenance personnel is left. With the rapi...

Problems solved by technology

[0009] According to the shortcomings of the underground pipeline space, especially the complex interior of the comprehensive pipeline gallery, the difficulty of comprehensive observation, and the difficulty of conducting full-scale fire experiments in multiple working conditions, the present invention provides a convenient and flexible comprehensive pipeline gallery fire smoke movement model device to solve the problem. It solves the problem of difficulties in full-scale experiments and small-scale experiments in the early stage of the development of integrated utility tunnels, and makes up for the blank spots in the experimental models of utility tunnels

This model device overcomes the difficulty of observing the smoke movement in the experiment, the inability to change the slope of the pipe gallery from multiple angles, the high cost of the experiment, the difficulty of realizing the comparison experiment of high-pressure water mist or other gas fire extinguishing facilities, and the difficulty of describing different structures and cabin pipe gallery models. The law of fire smoke, the difficulty of comparing the specific efficiency and effect of different fire detection devices in the pipe gallery, and the inability to change the ventilation mode can be used to analyze different pipe gallery structures, fire protection systems, fire detection devices, ventilation modes, fire source types, pipe Arbitrary combinations of corridor slopes, etc., to meet the needs of experimenters to carry out comprehensive pipe gallery ventilation and fire smoke simulation experiments under various complex working conditions
