Test device for simulating high temperature in tunnel fire

Abstract

The invention discloses a test device for tunnel fire simulation high temperature, and relates to the technical field of experimental equipment. The explosion-proof door assembly is arranged under the ground on the left side of the bottom plate; the plurality of temperature sensors are fixedly arranged in the top surface of the simulation tunnel at equal intervals; the axial flow fan is fixedly embedded in the right side wall of the simulation tunnel; the fire source placing groove is fixedly arranged on the right side wall in the simulation tunnel; a sealing door is rotationally arranged on the top surface of the box body through a hinge; the right end of the lead screw rotatably penetrates through the right side wall of the simulation tunnel through a bearing and then is fixedly connected with an output shaft of a first motor. A nut which is in threaded connection with the screw rod is fixedly connected with the interior of the box body; the temperature detection device is arranged in the box body; compared with the prior art, the tunnel in which a fire occurs can be simply simulated, meanwhile, the high-temperature condition in a vehicle running in the tunnel can be simulated, the internal temperature of a tunnel lining at the high temperature can be detected, and the safety performance of a simulation experiment is higher.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a test device for tunnel fire simulation high temperature. Background technique [0002] Highway tunnels are passages exclusively for automobile transportation. With the development of social economy and production, a large number of highways have appeared. Higher standards have been put forward for road construction technology, requiring straight lines, gentle slopes, and spacious road surfaces. Therefore, when the road passes through the mountainous area, the scheme of detour around the mountain in the past is mostly changed to the tunnel scheme. The construction of tunnels plays an important role in improving the technical status of highways, shortening running distances, increasing transportation capacity, and reducing accidents.

Problems solved by technology

[0003] With the increase of driving speed and density, coupled with the special structure and environmental conditions of the tunnel, once a vehicle fires in the tunnel, it is difficult for external rescuers to reach the scene in a short time to carry out rescue work, making it difficult for people to escape; at the same time, the tunnel When a fire occurs inside, the high temperature will damage the lining inside the tunnel, affecting the strength and service life of the tunnel lining; at this time, the research on tunnel fire is extremely important, so there is an urgent need for a test device for simulating high temperature in tunnel fire
