Technical Field

The invention relates to the technical field of rescue, in particular to an intelligent tunnel fire-extinguishing escape system.

Background

Tunnel fires often cause serious casualties, huge social influence and economic loss, and are one of the main disasters threatening the operation safety of tunnels. Due to the particularity of the spatial structure of the highway tunnel, the potential possibility of fire hazard is ubiquitous, tunnel fire accidents frequently occur in recent years, a large number of casualties and vehicle damages are caused, the top of a local tunnel collapses, and the traffic of the road section is in a paralysis state for a long time after the accident. The severe hazard of highway tunnel fires has attracted widespread attention from people around the world.

The tunnel fire accident has the following characteristics; 1. the spread is fast and is not easy to control. After a tunnel is subjected to fire disasters caused by vehicle accidents, car collisions, train overturn and the like, the tunnel carries a certain amount of fuel oil and also carries a certain amount of combustible articles, chemicals and dangerous articles, so that the fire spread is fast and difficult to control. 2. The channel is easy to block; the tunnel depth distance is long, the road surface is narrow, when the conflagration breaks out, a large amount of vehicles are difficult to evacuate in the tunnel, very easily cause the jam, and the intensity of a fire spreads along the vehicle, enlarges the loss. 3. Dense smoke is at high temperature and difficult to extinguish. After a fire disaster occurs in the tunnel, the underground space is quickly filled with smoke, and although ventilation equipment is arranged, the smoke is difficult to discharge in time. When a fire is caused by accidents such as vehicle collision, train overturn and the like in a tunnel, oil is burnt, the temperature is very high, fire extinguishers cannot approach the fire extinguishers, and the fire extinguishment time is prolonged; in addition, the system has the advantages of less population, severe environment, limited space and difficult communication. 4. Power supply interruption and difficult evacuation. After the fire occurs, the power supply is stopped, which brings great difficulty to the rescue work. The tunnel has long and narrow channel, poor lighting condition and low visibility after fire, people are difficult to evacuate in time, and trapped people are easy to scare, thereby resulting in greater disasters. 5. High-temperature toxic smoke is accumulated and is not easy to discharge. The underground closed environment ensures that high-temperature and toxic dense smoke generated by fire disaster is quickly accumulated and is not easy to discharge.

Not only seriously endangers the lives of the trapped people, but also makes fire brigade and other rescue personnel difficult to rescue in time.

Detailed Description

In order to make the purpose, technical solution and advantages of the present technical solution more clear, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.

As shown in fig. 1 to 9, the embodiment provides an intelligent tunnel fire extinguishing and escaping system, which includes water spraying heads 12, smoke sensors 13, an acoustic alarm, an escaping cabin 21, and a conveying belt assembly 22, wherein the acoustic alarm, the water spraying heads 12, and the smoke sensors 13 are all disposed at the top of a tunnel 10, the water spraying heads 12 have multiple groups, the multiple groups of water spraying heads 12 are disposed in one group at intervals along the extending direction of the tunnel 10, and one smoke sensor 13 is disposed between each group of water spraying heads 12; the tunnel 10 is provided with a lane 14, the conveying belt assembly 22 is arranged beside the lane 14, two ends of the conveying belt assembly 22 are respectively arranged at two ends of the tunnel 10, the escape compartment 21 is arranged on the conveying surface of the conveying belt assembly 22, the escape compartments 21 are arranged at intervals, and the escape compartment 21 can be transported to the opening of the tunnel 10 when the conveying belt assembly 22 operates.

As shown in fig. 1, a plurality of groups of sprinkler heads 12 are arranged on the top of the tunnel, a smoke sensor 13 is arranged between two adjacent groups of sprinkler heads 12, and as shown in fig. 2, the sprinkler heads 12 are arranged at intervals on the sector surface of the top of the tunnel.

As shown in fig. 5, the escape capsule 21 has a first driving block 211 at the bottom thereof, and the conveyor belt assembly 22 includes a driving wheel 221, a conveyor belt 222 and a second driving block 223, wherein the conveyor belt 222 surrounds the outside of the driving wheel 221, the second driving block 223 is disposed on the top conveying surface of the conveyor belt 222, the second driving block 223 abuts against the rear end of the first driving block 211, and the escape capsule 21 is driven to move by the second driving block 223 abutting against the first driving block 211 when the driving wheel 221 drives the conveyor belt 222 to move. As shown in fig. 4, when the driving force drives the belt 222 to rotate in the belt assembly 22, the second driving block 223 blocks the rear portion of the first driving block 211 to drive the escape compartment 21 to move forward, and if a blockage in the tunnel 10 is encountered, the belt assembly 22 drives the escape compartment 21 to push a passage away from the blockage, and the person in the escape compartment 21 is separated from the blockage area.

In order to facilitate the escape compartment 21 to push away the blockage, the diameter of the escape compartment 21 is gradually reduced from the vehicle body to the front end, so that the overall shape of the escape compartment 21 is streamlined, and the inside of the escape compartment 21 is provided with a personnel cabin 213 for accommodating the trapped personnel.

As shown in fig. 3, the escape compartment 21 and the top conveying surface of the conveyor belt 222 move in the same direction as the vehicle traveling direction of the adjacent lane 14. In a normal state, when the system is not used, when the vehicle is prevented from colliding with the escape capsule 21, the first driving block 211 and the second driving block 223 of the escape capsule 21 are abutted to form an effect similar to a rigid object.

As shown in fig. 4, in the moving direction of the escape capsule 21, the front end of the conveyor belt assembly 22 is provided with a supporting assembly 30, the supporting assembly 30 includes a supporting roller set 31 and a support 32, the supporting surface of the supporting roller set 31 is flush with and butt-jointed to the conveying surface of the conveyor belt assembly 22, and the supporting assembly 30 is used for supporting the escape capsule 21 transported out of the tunnel 10 from the tunnel 10. In addition, there are four first driving blocks 211, and the four first driving blocks 211 are respectively installed at corners of the escape capsule 21. As shown in fig. 6, in this arrangement, the first driving block 211 and the second driving block 223 can be in power connection, and the first driving block 211 can avoid the support roller set 31.

If the escape capsule 21 is left from the tunnel 10, the escape capsule 21 left from the tunnel 10 may not be transported in time, and therefore, the escape capsule 21 enters the supporting members 30, i.e., the supporting roller sets 31, and the escape capsule 21 is sequentially abutted in the front-rear direction, as shown in fig. 9. The escape capsule 21 is open on the side facing away from the lane 14, and the open side is used for people to leave the escape capsule 21 after the escape capsule 21 leaves the tunnel 10. At this time, the person can leave the escape capsule 21 through the open side of the escape capsule 21 on the side facing away from the lane 14. The escape capsule 21 is constructed substantially as shown in fig. 7.

The tail end of the escape capsule 21 is open, and the open end is used for people to enter and exit the escape capsule 21, so that the people can conveniently enter the escape capsule 21 through the open end at the rear part of the escape capsule 21.

The open side of the escape capsule 21, which faces away from the lane 14, and the open end at the tail of the escape capsule 21 are provided with expandable heat-insulating roller shutters, so that a heat-insulating effect is achieved, and internal personnel can be prevented from being burned by flame at the blocked position.

The escape capsule 21 has therein an emergency escape apparatus 212 for a person to wear to avoid inhalation of toxic gas. The effect of the person in the escape capsule 21 is shown in fig. 5.

As shown in fig. 10, specifically, the external power utilization module of the system supplies power to the MCU module, the first MCU module is in signal connection with the smoke sensor 13 to collect smoke signals, the system can also collect the temperature in the tunnel 10 through the temperature sensor, and when the signals collected by the temperature sensor and the smoke sensor 13 exceed a threshold, the sound alarm generates an alarm signal. At this moment, the first MCU module transmits a control signal to the second MCU module through a ZigBee mode, the second MCU module starts the regulating valve to open the sprinkler bead 12 corresponding to the region, so that the sprinkler bead 12 is sprayed with water, and the collected water in the tunnel 10 is discharged through the water drainage channel 15. Meanwhile, the second MCU module drives the conveyer belt assembly 22 to operate by means of a driving motor.

Specifically, as shown in fig. 8, when a car accident occurs in the tunnel 10, and a person is trapped in the area of the enclosed line a due to blockage at the position shown by the enclosed line a, after the smoke sensor 13 and the temperature sensor detect that smoke and temperature both exceed the threshold value, the water spray heads 12 between the enclosed lines a and adjacent to the outer sides of the enclosed lines a are controlled to spray water to form a water spraying area B, the area of the enclosed line a is sprayed with water to extinguish a fire and reduce the temperature, and meanwhile, the sound alarm gives out a sound alarm, and after the person enters the escape capsule 21 from the tail end of the escape capsule 21, the emergency escape device 212 is opened and worn to avoid sucking too much harmful gas. The sound emitted by the sound alarm is gradually rapid, after the last countdown prompt, the motor of the conveyor belt assembly 22 is started, the driving wheel 221 drives the conveyor belt 222 to rotate, and the conveyor belt 222 drives the escape capsule 21 to advance in a mode that the second driving block 223 pushes the first driving block 211 until people in the area of the closed line A leave the area of the closed line A. The person leaving the danger area can leave the escape capsule 21 through the rear end of the escape capsule 21.

When the danger area, for example, the closed line a, is located at the end of the tunnel 10, the escape capsule 21 is moved onto the support member 30 after being detached from the conveyor belt member 22, and the escape capsule 21 is formed as shown in fig. 9, so that the person can leave the escape capsule 21 through the side open end of the escape capsule 21.

The system can monitor signals through the smoke sensor 13 at the first time when a fire disaster happens in the tunnel 10, then drench and extinguish the fire through the sprinkler head 12 and alarm through the sound alarm. The person trapped in the tunnel 10 can enter the escape capsule 21, and the escape capsule 21 is driven by the conveyor belt assembly 22 to advance until the escape capsule 21 leaves the trapped area. The escape capsule 21 is optimized in structure, and can enter from the rear or escape from the side after the escape capsule 21 leaves the tunnel 10. The supporting member 30 is used to prevent the escape capsule 21 moving out of the tunnel 10 from being stacked, thereby facilitating the escape of people.

The foregoing is only a preferred embodiment of the present invention, and many variations in the specific embodiments and applications of the invention may be made by those skilled in the art without departing from the spirit of the invention, which falls within the scope of the claims of this patent.
