Description

Technical Field

[0001] The utility model relates to the technical field of tunnel refuge, in particular to an emergency refuge device for a tunnel. Background Art

[0002] At present, in tunnel accidents, since a car accident usually occurs inside the tunnel, a fire or tunnel congestion may occur, which makes it difficult for people inside the tunnel to escape after a fire occurs in the tunnel, resulting in serious casualties. In order to solve the current problem of difficulty in escaping from a fire inside the tunnel, a refuge room is often set up next to the tunnel. The refuge room can provide a place for people to escape and hide in the event of an accident in the tunnel, thereby protecting human life to the greatest extent. However, the existing tunnel refuge structure still has the problem of not being able to protect all vehicles in the tunnel door and being unable to prevent the flame from invading inward.

[0003] Therefore, it is very necessary to invent a kind of tunnel emergency refuge device. Utility Model Content

[0005] The flame retardant refuge structure includes a support frame, a gas storage tank, an air duct, a control valve and a dispersion seat, and the support frame is fixedly installed on the top of the tunnel capping, and the gas storage tank is fixedly installed inside the support frame; the air duct is fixedly installed at one end of the gas storage tank, and the control valve is fixedly installed at one end of the air duct and extends downward; the dispersion seat is fixedly installed at the bottom of the tunnel support frame and is connected to the control valve.

[0006] The refuge tunnel adopts an auxiliary tunnel which is perpendicular to the tunnel body, and the outer sides of the refuge tunnel and the tunnel body are both surrounded by the mountain. The refuge tunnel adopts several tunnels; the refuge tunnels are evenly distributed on both sides of the tunnel body, and the refuge tunnel is divided into two parts, inner and outer parts, by isolating and sealing doors. The rear end of the refuge tunnel is provided with a space which can accommodate several cars, and a large number of oxygen cylinders are placed inside the refuge tunnel for normal breathing of the people inside, so as to form an independent space, which is used to form a refuge space when a fire or other danger occurs inside the tunnel body, so as to prevent the dangerous situation inside the tunnel body from endangering the safety of surrounding vehicles, and the distribution of the refuge tunnels can protect vehicles at various positions inside the tunnel body.

[0007] The gas storage tank inside the flame-retardant refuge structure is a steel metal tank, and a large amount of inert gas is stored inside the gas storage tank. The control valve is an electrically controlled stop valve; the control valve is triggered by the flame sensor control under the tunnel cap, and the dispersion seat is a rectangular dispersion seat. A rectangular space will be formed between the tunnel body and the isolation door to facilitate vehicles to turn into the refuge tunnel, and a large amount of inert gas will be dispersed through the tunnel cap. Inert gases such as nitrogen and carbon dioxide can also be used as flame-retardant gases. They usually suppress the burning of flames by excluding oxygen. These gases are relatively harmless to the human body and form a flame-retardant space to prevent the flame from continuing to attack the interior of the refuge tunnel.
