Special water spray fire resisting shutter device for tunnel

Abstract

The invention provides a special water spray fire resisting shutter device for a tunnel. The special water spray fire resisting shutter device for the tunnel solves the technical problem that the fire-resistant limiting temperature of existing fire fighting resisting shutter is not high. The special water spray fire resisting shutter device for the tunnel comprises a fixed shutter (3), a flexible shutter (2), a shutter gate box (8), a shutter motor box (22), a reversible smoke exhaust fan (4), a fire fighting water supply main pipe (27), water distribution branch pipes (24) and a water spray nozzle (23); two fire resisting shutters are arranged at the connecting positions of a tunnel parking area (10) and a tunnel driving area (20); the fixed shutter (3) is arranged between the shutter gate box (8) and an arched cave roof of the tunnel; the flexible shutter (2) is arranged under the shutter gate box (8); and the water distribution branch pipes (24) which are communicated with the fire fighting water supply main pipe (27) are arranged in the middles of two flexible shutter guide rails (9) which are vertically arranged on the bilateral vertical tunnel walls respectively. According to the special water spray fire resisting shutter device for the tunnel, the fire-resistant limiting temperature of the fire resisting shutters is effectively reduced and the costs are saved.

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
