High-pressure water curtain fire-extinguishing system with functions of smoke blocking, time delay and lifesaving

Abstract

The invention relates to a high-pressure water curtain fire-extinguishing system with the functions of smoke blocking, time delay and lifesaving, which is characterized by comprising a water supply pipeline, a horizontal main pipe and a smoke sensing and alarm device, wherein the horizontal main pipe and the smoke sensing and alarm device are connected with the water supply pipeline, a water supply valve, a temperature sensing fire-proof valve and a drainage and gas inlet valve are connected on the water supply pipeline respectively through pipelines, first elbows which are bent downwards are connected at the two end parts of the horizontal main pipe respectively, the first elbows are connected with second elbows which are bent downwards and inwards through pipe connecting parts, and spray nozzles are arranged on the second elbows. The high-pressure water curtain fire-extinguishing system has the advantages that: when a fire disaster happens, the effects of blocking and absorbing smoke fog and heat of a high-pressure water curtain are utilized for isolating a unit from smoke and fire, thereby preventing the smoke fog and hot air from entering into the unit, keeping oxygen in the unit and providing living space and rescue and escape space for trapped staff. Simultaneously, the system further has the functions of utilizing water fog for fire extinguishing and effective cooling, thereby effectively solving the difficult problems of fire prevention, fire extinguishing and rescue of high buildings.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a high-pressure water curtain fire extinguishing system with functions of smoke barrier, time delay and lifesaving. Background technique [0002] When a fire breaks out in a building, it is very easy to produce a chimney effect, which often brings certain difficulties to the rescue work, especially in high-rise buildings and super high-rise buildings. At this time, most of the safe passages have become pyrotechnic passages and cannot be used. Even if they can be used, the trapped people in the room cannot reach the safe passage from the room, because once the door is opened, the fireworks will quickly burn throughout the room, causing trapped people to escape. Personnel were engulfed in flames and could not get out. In addition, due to the limited spraying height of fire-fighting equipment, it is often out of reach for high-rise buildings, which has become a worl...

Problems solved by technology

[0002] When a fire breaks out in a building, it is easy to generate a chimney effect, which often brings certain difficulties to the rescue work, especially in high-rise buildings and super high-rise buildings.

At this time, most of the safe passages have become pyrotechnic passages and cannot be used. Even if they can be used, the trapped people in the room cannot reach the safe passage from the room, because once the door is opened, the fireworks will quickly burn throughout the room, causing trapped people to escape. people caught in the flames and unable to get out

In addition, due to the limited spraying height of fire-fighting equipment, high-rise buildings are often out of reach, which has become a worldwide problem and often causes heavy casualties
