Description

Technical Field

[0001] The utility model relates to the field of tunnel engineering, in particular to a temporary fire refuge accommodation room in a long tunnel. Background Art

[0002] With the continuous development of the transportation network, there are more and more vehicles, which makes the roads more crowded. Therefore, many roads are expanded. When encountering mountains, people use tunnels to build roads. In extra-long tunnels, the scope of fire is sometimes not large, but because of the smoke problem in the confined space, the distance to evacuate to both sides is too long, resulting in casualties. Therefore, it is very necessary to consider setting up emergency shelters in the tunnel. The existing temporary shelters only have fire isolation measures. When a fire accident occurs in the tunnel, it cannot promptly remind vehicles that have not entered the tunnel to avoid vehicle congestion. And the fire accident information is not fed back to the road monitoring center, and rescue is not carried out in the first time. Summary of the invention

[0003] The utility model aims to provide a temporary fire shelter in a tunnel in view of the deficiencies in the prior art, which has a simple structure and prevents vehicles from entering and being blocked in the tunnel, thus facilitating safe rescue.

[0004] The technical solution adopted by the purpose of the utility model is:

The left and right sides of the horizontal tunnel are respectively provided with a first fire door to form a temporary refuge room. The fire monitoring sensor and the fire warning light are respectively arranged above the tunnels on both sides. The fire monitoring sensor and the fire warning light are respectively electrically connected to the controller. The controller is used to communicate with the road monitoring center through a wireless network. The power supply system is used to supply power to electrical equipment. When a fire hazard occurs in the tunnel on one side, the fire warning light of the tunnel on the other side lights up, prompting the driver to leave a rescue passage for easy rescue. And it is relatively safer for people to escape from the tunnel on the other side.

[0006] Furthermore, the temporary shelter is provided with oxygen cylinders, seats, a television, a toilet, lighting equipment and a ventilation passage, and the ventilation passage is provided with an exhaust fan and a one-way check valve.

DETAILED DESCRIPTION Specific embodiment 1:

[0028] See also Figure 1 and Figure 2 As shown, a temporary refuge room for fire in a long tunnel includes a horizontal tunnel 1 connecting the tunnels on both sides, a power supply system 2, a controller, a fire monitoring sensor and a fire warning light 9. The first fire door 4 is respectively provided on the left and right sides of the horizontal tunnel 1 to form a temporary refuge room 5. A signboard for the temporary refuge room is provided in the tunnel, so that the temporary refuge room can be entered according to the signboard when a fire occurs. Both side walls of the horizontal tunnel are also provided with explosion-proof walls 6 to improve the explosion-proof safety performance. Each of the first fire doors 4 is an outward-opening door to prevent vagrants from entering the temporary refuge room to live, and a one-way door is used to prevent people from walking into the tunnel of the accident party when they are not clear about the situation, or failing to lock it in time to cause secondary disasters. The temporary refuge room 5 is provided with oxygen cylinders, seats, toilets, televisions, lighting equipment and ventilation channels 7. The oxygen cylinders can also be provided with oxygen production. The ventilation channel 7 is provided with an exhaust fan and a one-way check valve to facilitate people to temporarily avoid smoke and have a certain ventilation effect. A second fire door 8 is also provided on the left and right sides of the temporary refuge accommodation room 5, and a smoke isolation chamber 3 is formed between the first fire door and the second fire door 8. The width of the smoke isolation chamber is greater than that of the temporary refuge accommodation room, thereby improving the fire and smoke prevention performance of the temporary refuge accommodation room.

[0029] The fire monitoring sensor and the fire warning light 9 are respectively arranged above the tunnels on both sides. The fire monitoring sensor and the fire warning light 9 are arranged at a certain distance. In this specific embodiment: a fire monitoring sensor and a fire warning light 9 are arranged at an interval of 50 to 100 meters, and a fire indicator light is arranged for each lane. The fire monitoring sensor and the fire warning light are respectively electrically connected to the controller. The fire monitoring sensor is used to monitor the occurrence of a fire in the tunnel and send it to the controller. The controller controls the fire warning light to light up according to the received information, and prohibits vehicles from continuing to enter the tunnel. In this specific embodiment, the fire indicator lights of the tunnels on both sides can be set to red lights on the side where the fire occurs and yellow lights on the other side. The yellow lights flash to remind people to avoid danger and let the vehicles drive on the other side to leave lanes for emergency vehicles; the red lights flash to stop entering the tunnel. The controller is used to communicate with the road monitoring center through a wireless network. The controller can send fire information to the road monitoring center and can also receive the accusation information of the monitoring center line. The power supply system is used to supply power to electrical equipment.

[0030] The door locks of the first fire door are all smart locks, and mechanical locks can also be used. The smart locks are electrically connected to the controller, and the controller communicates with the road monitoring center, so that the road monitoring center can control the smart locks to open or close the first fire door for remote operation. An emergency switch box 11 is set next to the first fire door, and a hammer is set next to the emergency switch box to open the emergency switch box. If a mechanical lock is used, a key is placed in the emergency switch box 11; if a smart lock is used, a start button is set in the emergency switch box 11, and the start button is connected to the controller. When the start button is pressed, the controller starts the smart lock to open the first fire door. This prevents the first fire door from being opened at will and avoids being occupied by others.

[0031] Possibly, it also includes an openable and closable status indicator light 10, which is electrically connected to the controller. The controller can determine whether the first fire door on this side can be opened based on the information received from the smart lock or the fire monitoring sensor. When the first fire door on one side can be opened, the openable and closable status indicator light 10 lights up green; when the first fire door on one side cannot be opened, the openable and closable status indicator light 10 lights up red.

[0032] Possibly, it also includes an intercom, which is used to communicate with the road monitoring center through a wireless network, so as to facilitate timely dialogue with the road monitoring center and reflect the real situation in the tunnel, so that the monitoring center can make correct and timely rescue command work.
