Definitions

• the invention relates to a system for extinguishing tunnel fires. Recently, tunnel fires have become more and more catastrophic.
• the object of the invention is therefore to provide an effective, simply constructed system for fighting tunnel fires.
• a curtain is provided at a distance of, for example, 50 m to 200 m, which can be closed in the event of a fire, for example lowered. This closes the tunnel section if a fire has been detected by the fire sensor in this section.
• the curtain consists of a non-combustible material, for example a fabric made of fibers made of inorganic material.
• the curtain is preferably rolled up or folded onto the tunnel ceiling. It consists of vertically running, overlapping strips. This will close the curtain even if there is a vehicle underneath. If a vehicle catches fire, the fire sensor in this section, for example a smoke sensor and / or heat sensor, actuates the curtains, that is to say completely low, in order to close the section in which the burning vehicle is located.
• the fire sensor in this section for example a smoke sensor and / or heat sensor
• the shut-off devices that close the openings of the extinguishing agent line to this section are opened.
• the shut-off element can be designed, for example, as an electromagnetic valve which is actuated by the fire sensor, that is to say is opened.
• the openings can be provided on a fire extinguishing agent line that extends along the tunnel. The distance between the openings can be, for example, 5 m to 30 m.
• the openings are preferably designed as nozzles.
• Halon is preferably used as the fire protection agent.
• the smoke that has already formed is then extracted by the fans in the tunnel. Immediate rescue operations can also begin, as there is little smoke and heat.
• the windows of the vehicles should be closed and the ventilation should be switched off so that sufficient oxygen is available in the vehicle until the halon is extracted by the exhaust air fans. Since it quickly evaporates, the halon cannot cause any major health damage.
• the car can have a fire extinguishing agent storage container which supplies a fire protection agent supply device in the car.
• the car has a fire sensor, for example a smoke detector or a heat sensor, which actuates the fire protection agent supply device in the event of a fire to supply fire protection agents. Halon is also preferred as the fire protection agent.
• FIG. 1 shows a cross section through a tunnel with the curtain rolled up on the ceiling
• FIG. 2 is a view according to FIG. 1 but with the curtain lowered;
• Fig. 3 shows a longitudinal section through a section of the tunnel with curtains lowered.
• a fire sensor 2 and a rolled-up curtain 3 are provided in a tunnel 1 on the ceiling.
• lines 4, 5 extend along the tunnel, via which a fire extinguishing agent, e.g. Halon is fed.
• a fire extinguishing agent e.g. Halon
• the fire sensor 2 for example a smoke detector and / or a heat sensor, detects a fire in a tunnel section (A), the two curtains 3 of this section are lowered (FIG. 3).
• the curtains 3 consist of vertical strips 6 which overlap.
• section A is supplied with fire extinguishing agent via nozzles in lines 4, 5.
• the shut-off devices that close the nozzles are opened via the fire sensor 2.
• the flue gas and halon formed are removed in this section by the fan 7.
