Embodiment
[0021] A tunnel 1 automatic fire extinguisher, such as figure 1 As shown, it includes air suction pipes arranged on both sides of the bottom of the inner wall of the tunnel 1 and a water tank 2 arranged on the top of the outer wall of the tunnel 1 .
[0022] combine Figure 2-Figure 5 , the air extraction main road 5 is fixedly arranged along the length direction of the tunnel 1, and is in the shape of a cuboid with a hollow interior. The two ends of main air extraction road 5 are detachably provided with exhaust fans. When the exhaust fan is connected with the main air extraction channel 5, a connecting pipe 9 needs to be used. One end of the connecting pipe 9 has a rectangular cross-section and can be connected with the end of the main air extraction road 5. The other end of the connecting pipe 9 has a circular cross-section and can Connect with exhaust fan. The upper end of the air suction main channel 5 is provided with several air suction ports, and the upper end of th...

The invention relates to the field of tunnels and particularly discloses an automatic fire extinguisher for a tunnel. The automatic fire extinguisher for a tunnel comprises air exhaust pipelines arranged on two sides of a bottom part of an inner wall of the tunnel and water tanks arranged on a top part of an outer wall of the tunnel, a plurality of air exhaust openings are formed in main air exhaust pipelines, first flexible pipes are arranged on the air exhaust openings, and exhaust fans are detachably arranged at two ends of the main air exhaust pipelines; water outlet pipes are arranged on the water tanks, main water spraying pipelines are fixedly arranged in the main air exhaust pipelines, water outlet pipes extend into the main air exhaust pipelines and communicate with the main water spraying pipelines, communicating pipes communicate with the main water spraying pipelines, a plurality of water spraying openings are formed in the main air exhaust pipelines, the communicating pipes communicate with lower ends of the water spraying openings, and second flexible pipes are arranged at upper ends of the water spraying openings; and fire extinguishing pipes is arranged on the main air exhaust pipelines, an air cavity and a water cavity are formed in each fire extinguishing pipe, the air cavity communicates with the first flexible pipe, and the water cavity communicates with the second flexible pipe. The automatic fire extinguisher for a tunnel aims to solve technical problems that smoke in the tunnel affects personnel safety and increases rescue difficulty when a fire occurs.
Description
technical field [0001] The invention relates to the field of tunnels, and specifically discloses an automatic fire extinguisher for tunnels. Background technique [0002] In the tunnel, because the light changes greatly when driving into or out of the tunnel, it is easy to produce white hole effect and black hole effect, so if the driver does not slow down, it is easy to cause traffic accidents and cause the vehicle to catch fire. When the fire point of the vehicle is close to the tunnel entrance, the smoke can be quickly discharged to the outside of the tunnel without causing smoke to accumulate inside the tunnel, and it is more convenient for firefighters to extinguish and rescue the fire; when the fire point of the vehicle is in the middle of the tunnel, a large amount of smoke cannot Exhaust, it is easy to cause smoke burns, suffocation and other injuries to people in the tunnel, and it is not easy for firefighters to carry out fire fighting and rescue under the influenc...
