Special water spray fireproof shutter device for tunnel

Abstract

The invention provides a special water spray fireproof shutter device for a tunnel, which solves the technical problem of low fireproof extreme temperature of a traditional fire shutter. The special water spray fireproof shutter device for the tunnel comprises a fixed shutter (3), a movable shutter (2), a shutter brake box (8), a shutter motor box (22), a retractable smoke extraction fan (4), a fire water-supply main pipe (27), water distribution branch pipes (24) and a water spray nozzle (23); two fireproof shutter devices are arranged at the connection of a tunnel parking area (10) and a tunnel traveling area (20); the fixed shutter (3) is arranged between the shutter brake box (8) and an arched roof of the tunnel; the movable shutter (2) is arranged under the shutter brake box (8); and the water distribution branch pipes (24) communicated with the fire water-supply main pipe (27) are arranged between two movable shutter lead rails (9) vertically arranged on each vertical wall of the tunnel. The special water spray fireproof shutter device for the tunnel effectively improves the fireproof extreme temperature of the shutter and saves the cost.

Description

technical field [0001] The invention relates to a fire-fighting equipment, in particular to a fire-extinguishing device for a special fire-proof roller shutter device for a tunnel. Background technique [0002] Tunnel fire extinguishing is a technical problem in the field of fire protection. When a fire occurs in a tank truck transporting flammable and flammable liquids in a tunnel, the fire temperature is as high as 1000-1200 °C, and the flowing flammable liquid will flow along the longitudinal slope of the road in the tunnel. Flow downwards to expand the fire area; the existing water fire extinguishing system in the tunnel, while spraying and extinguishing the fire, the water flowing on the ground will float and spread the burning fuel oil floating on it, which promotes the spread of the fire. In addition, because the tunnel is a cavern structure, when a fire occurs, the smoke from the fire will spread to the entrance and exit of the tunnel, making it impossible for firefi...

Problems solved by technology

[0003] The invention solves the technical problem that the existing fire-fighting roller blinds are not suitable for tunnels, and the fire-resistant limit temperature of the existing fire-fighting roller blinds is not high. To increase the fire-resistant limit temperature, the manufacturing cost of the roller blinds needs to be increased, and provides a tunnel-specific The water spray fire-proof roller shutter device is especially suitable for effectively responding to fires caused by flammable liquids in tunnels, and at the same time increases the fire-resistant limit temperature of the roller shutter without increasing the cost of the roller shutter
