Tunnel automatic fire extinguishing machine

Abstract

The invention discloses a tunnel automatic fire extinguishing machine. Two dust pipes are arranged at the top of a tunnel; dust cavities are formed in the dust pipes; multiple butt joint ends are arranged on the dust pipes; first communicating holes correspondingly communicating with the dust cavities are formed in the butt joint ends; first slide shafts sliding in the first communicating holes are arranged on the butt joint ends; sealing heads for controlling opening or closing of the first communicating holes are arranged on the first slide shafts; the butt joint ends are provided with buttjoint grooves correspondingly communicating with the first communicating holes; the butt joint grooves are conical; multiple control rods are arranged on two sides of the tunnel; and clamping heads are arranged at one ends of the control rods. The machine can achieve a fire extinguishing effect through fire extinguishing dust in the dust cavities, and prevents the problem of lower fire extinguishing effect caused by traditional vehicle fire extinguishers.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a tunnel automatic fire extinguisher, in particular to a tunnel automatic fire extinguisher capable of extinguishing a vehicle when a fire occurs in a tunnel. Background technique [0002] With the continuous development of science and technology, the continuous development of road construction level has been further promoted. In the current road construction, tunnels are one of the common construction methods, so that vehicles can be further facilitated to drive through the mountains through tunnels. Among them In the current tunnel construction process, most of them are simple cave structures. When a vehicle fires in the tunnel, it can only be extinguished by the fire extinguisher carried by the vehicle. Although the fire extinguisher can achieve the purpose of extinguishing the fire, due to the The fire extinguisher's fire extinguishing ability is limited, so it can't effectively...

[0002] With the continuous development of science and technology, the continuous development of road construction level has been further promoted. In the current road construction, tunnels are one of the common construction methods, so that vehicles can be further facilitated to drive through the mountains through tunnels. Among them In the current tunnel construction process, most of them are simple cave structures. When a vehicle fires in the tunnel, it can only be extinguished by the fire extinguisher carried by the vehicle. Although the fire extinguisher can achieve the purpose of extinguishing the fire, due to the The fire extinguisher's fire extinguishing capacity is limited, so it cannot effectively extinguish the fire of the vehicle, which will further cause danger to the vehicle and the personnel in the tunnel due to the fire
