Intelligent automatic monitoring, fire extinguishing and smoke exhausting device and method for highway tunnel

Abstract

The invention discloses an intelligent automatic monitoring, fire extinguishing and smoke exhausting device and method for a highway tunnel. The device for implementing the method comprises an infrared thermography temperature measurement module, a pipeline bracket, a self-smoke-exhausting corridor standard section and a self-smoke-exhausting corridor tunnel outer section. Based on the infrared thermography temperature measurement technology, the temperature of tires of a vehicle running in a tunnel and the temperature outside a compartment are measured, the vehicle with the tires on fire is positioned, and a fire extinguishing agent pipeline with a directional spray head and a self-smoke-discharging pipeline with a directional smoke discharging port are arranged in the tunnel; infrared thermography temperature measurement modules are arranged on the two sides of the inner wall of a tunnel structure at fixed intervals. A self-smoke-discharging corridor is arranged on the top of the inner wall of a tunnel in a full-length mode and led to the outside of the tunnel, directional smoke discharging ports are reserved in the bottom of the corridor according to fixed intervals, and after the position of a fire vehicle in the tunnel is positioned, a smoke discharging port opening and closing control module opens the directional smoke discharging ports near the fire position; the problem of smoke exhaust in the tunnel is solved, and the purposes of energy conservation and smoke exhaust are achieved.

Description

technical field [0001] The invention belongs to the technical field of road tunnel management and maintenance, and is mainly used in the fire prevention and control technology for daily operation of road tunnels. Background technique [0002] During the operation of road tunnels, fire accidents may occur in the tunnel. Due to the characteristics of the road tunnel with relatively closed structure and poor ventilation environment, it is difficult to carry out rescue work in the event of a fire, often resulting in serious accident consequences. When a fire occurs, the high temperature and smoke generated will seriously threaten the safety of personnel in the tunnel. In the current tunnel operation and management process, the fire prevention and control measures mainly include the use of fixed or hand-held fire-fighting facilities to extinguish the fire in the tunnel. Use fans and other facilities to control the smoke in the tunnel. [0003] The above prevention and control fa...

AI Technical Summary

Problems solved by technology

[0003]The above prevention and control facilities and methods all have their own shortcomings: (1) The fire in the tunnel cannot be located in time, and the initial source of the fire cannot be identified clearly

During tunnel operation, vehicle spontaneous combustion accounts for a relatively high proportion of fire causes. During long-distance driving, vehicle tires and goods tend to generate high temperatures due to friction, and the accumulation of energy causes vehicles to spontaneously ignite. Vehicles are in a driving state in the tunnel. There is uncertainty in the time when the driver discovers the fire. After taking braking measures, the location of the fire is also random. As a result, the tunnel operation and maintenance management personnel cannot determine the location of the fire in the first place.

(2) There is a lag in fire rescue in the tunnel, and it is impossible to take relevant measures to extinguish the fire in the tunnel in time

At present, fires in tunnels are mainly extinguished by manual operation of fire safety facilities, and the location of fire safety facilities in tunnels is fixed. It takes a certain amount of time from the discovery of the fire to the manual implementation of relevant measures, which delays the initial rescue time of the fire.

(3) Fans and fire-fighting facilities in the tunnel are usually set at a certain distance. Due to the uncertainty of the location of the fire in the tunnel, when the fire location is far away from the fan and fire-fighting safety facilities, the efficiency of smoke and fire control in the tunnel decreases, making it difficult to It plays a role in timely and effective control of tunnel smoke concentration and fire consequences. Therefore, it is necessary to improve the accuracy and effectiveness of fire prevention and control measures in tunnels to ensure the safety of tunnel operations.
