Embodiment 1

[0039] On the basis of the above structure, in this embodiment, the tunnel main body 1 is assembled from multiple short tunnels 24 with the same structure, and two adjacent short tunnels 24 are connected in a way that those skilled in the art can think of, for example, in the corresponding Two flanges are respectively welded at the opposite ends of the two short tunnels 24, and the two flanges are fixed together by bolts. The joints of the two flanges are fixed with fireproof sealant by glue, which has a simple structure and is easy to assemble. ,save time and energy.

Embodiment 2

[0041] On the basis of Embodiment 1, in this embodiment, the bottom of the tunnel main body 1 is provided with a fixed base 4 and a lifting base 5 at the positions close to the two ends respectively, and the two ends of the tunnel main body 1 are connected with the fixed base 4 and the lifting base 5 respectively. The lifting base 5 is rotatably connected, and the lifting base 5 can drive one end of the tunnel main body 1 to move up and down. During the fire simulation process, one end of the tunnel body 1 moves up and down by lifting the base 5, thereby simulating the tunnel body 1 with different slopes, so as to analyze the analysis of smoke inside the tunnel body 1 with different slopes when a fire occurs.

[0042] The lifting base 5 includes a hydraulic cylinder, the telescopic end of the hydraulic cylinder is vertically upward, and is connected to the bottom of one end of the tunnel body 1 through a hinge; in order to increase the stability of the hydraulic cylinder, a bas...

Embodiment 3

[0046] On the basis of Embodiment 1, in this embodiment, the fire source simulation device includes a burner 6 and a gas bottle 7. The burner 6 is preferably a porous burner, and the burner 6 can be moved up and down and installed in the tunnel body 1 close to the opening. The gas bottle 7 is arranged outside the tunnel body 1, and communicates with the burner 6 through the gas supply pipe 8 passing through the opening, and the part of the gas supply pipe 8 outside the tunnel body 1 is spaced sequentially from the gas bottle 7 to the burner 6 On-off control valve 9, pressure gauge 10 and flowmeter 11 are installed, and above-mentioned on-off control valve 9, pressure gauge 10 and flowmeter 11 all adopt prior art, and the installation mode that it is installed on the air supply pipe 8 adopts prior art equally, The flow meter 11 is preferably a rotameter, and the switch control valve 9 is preferably an electronic valve. The burner 6 is placed at the opening in the tunnel main bo...

Abstract

The invention relates to a multifunctional tunnel fire side key smoke discharge simulation platform comprising a tunnel main body, a smoke discharge channel, a fire source simulation device, an air supply device and a fire detection device; one end of the tunnel main body can move up and down, at least one opening is formed in the bottom of the tunnel main body, and the fire source simulation device is arranged at the opening and is used for simulating a fire; the two ends of the smoke discharge channel are both open, one side of the smoke discharge channel is open, the other side of the smokedischarge channel is closed, the open side of the smoke discharge channel is fixedly installed on one side of the tunnel main body, and a plurality of smoke outlets in communication with the smoke discharge channel are uniformly formed in one side of the tunnel main body at intervals; the air supply device is arranged at one end of the tunnel body and is used for supplying air to the tunnel body,and the fire detection device is arranged in the tunnel main body and is used for detecting the fire situation in the tunnel main body. The simulation platform in the invention has the beneficial effects that the situation of fire combustion in the tunnel main body under different conditions is simulated, the distribution condition of the smoke gas and the fire law in the tunnel main body are observed, and a theoretical experimental basis is provided for construction of actual tunnels.

Description

technical field [0001] The invention relates to the technical field of tunnel fire safety, in particular to a multifunctional simulation platform for emphasizing smoke exhaust at the side of a tunnel fire. Background technique [0002] Fire is one of the biggest risks to tunnel operations. The driving environment in the main body of the tunnel is closed, and it is difficult to evacuate and rescue after a fire occurs, which is likely to cause huge casualties, property losses and adverse social impacts. According to the investigation results, it is shown that most of the victims were poisoned and suffocated due to the thick smoke and poisonous gas produced by the fire. Therefore, how to effectively control the flow of smoke to ensure the safety of personnel evacuation has become an important research content of tunnel fires. [0003] At present, the common tunnel fire experiment platform is to study the control and temperature distribution of smoke under the longitudinal ven...
