Intelligent tunnel fire extinguishing escape system

Abstract

The invention relates to the technical field of rescue, in particular to an intelligent tunnel fire extinguishing escape system. The intelligent tunnel fire extinguishing escape system is characterized in that a sound alarm, multiple groups of sprinkler heads and smoke sensors are arranged at the top of a tunnel, the multiple groups of sprinkler heads are arranged at intervals in the extension direction of the tunnel, one smoke sensor is arranged between each group of sprinkler heads, a lane is arranged in the tunnel, a conveying belt assembly is arranged beside the lane, the two ends of the conveying belt assembly are located at the two ends of the tunnel respectively, escape cabins are placed on the conveying face of the conveying belt assembly, the multiple escape cabins are arranged at intervals, and when the conveying belt assembly operates, the escape cabins can be conveyed to a tunnel portal. The system can achieve intelligent fire extinguishing and personnel escape, and the probability that personnel are trapped is reduced.

Description

technical field [0001] The invention relates to the technical field of rescue, in particular to an intelligent tunnel fire extinguishing and escape system. Background technique [0002] Tunnel fire often causes serious casualties, huge social impact and economic loss, and is one of the main disasters that threaten the safety of tunnel operation. Due to the particularity of the spatial structure of highway tunnels, the potential for fires is ubiquitous. In recent years, tunnel fire accidents have occurred frequently, causing a large number of casualties and vehicle damage, causing the top of the tunnel to collapse, and causing the road section to collapse. Traffic has been paralyzed for a long period of time after the incident. The severity and hazards of highway tunnel fires have aroused widespread concern from people all over the world. [0003] Tunnel fire accidents have the following characteristics: 1. It spreads quickly and is difficult to control. After a fire is ca...

AI Technical Summary

Problems solved by technology

[0003] Tunnel fire accidents have the following characteristics; 1. Rapid spread and difficult control

After a fire occurs in a tunnel due to vehicle accidents, car collisions, train overturns, etc., in addition to carrying a certain amount of fuel, sometimes it also carries a considerable amount of combustible materials, chemicals, and dangerous goods. The fire spreads quickly and is difficult to control

2. The channel is easy to be blocked; the tunnel is long in depth and the road surface is narrow. When a fire occurs, it is difficult for a large number of vehicles in the tunnel to evacuate, which is easy to cause blockage. The fire spreads along the vehicles and expands the loss

3. Thick smoke and high temperature make it difficult to fight

After a fire broke out in the tunnel, the smoke quickly filled the underground space. Even with ventilation equipment, it was difficult to discharge the smoke in time

When a fire occurs in the cave due to accidents such as vehicle collisions and train overturns, the oil will burn and the temperature will be very high, which often prevents firefighters from approaching and prolongs the fire extinguishing time; in addition, the population is small, the environment is harsh, and due to space constraints, communication is difficult.

4. Power interruption and difficult evacuation

[0004] This not only seriously endangers the lives of the trapped people, but also makes it difficult for the fire brigade and other rescuers to rescue them in time.
