Automatic water spraying and fire extinguishing system for building outer wall

Abstract

The invention relates to an automatic water spraying and fire extinguishing system for a building outer wall. The system comprises: a high-position fire-fighting water tank arranged on the roof of a building and used for storing water; a plurality of spraying devices used for spraying fire floors; water pipes which are communicated with the high-position fire-fighting water tank and the spraying devices so as to guide water in the high-position fire-fighting water tank to the spraying devices; a plurality of detection devices which are used for detecting the state of the building wall body in real time and outputting corresponding detection signals; and a main control module which is connected with the plurality of detection devices and the plurality of spraying devices, and is used for receiving the detection signals of the plurality of detection devices, judging the fire state of the building wall according to the detection signals, and controlling the spraying devices at the corresponding positions to be started when determining that the building wall has a fire point, wherein each floor is provided with at least one spraying device and at least one detection device. The automatic water spraying and fire extinguishing system has the effect of automatically spraying water to extinguish fire when the building outer wall is on fire.

Description

technical field [0001] This application relates to the field of fire safety, in particular to an automatic sprinkler system for exterior walls of buildings. Background technique [0002] When a fire breaks out in a residential building, it will often cause damage to the property of the residents, and even endanger the lives of the residents when it is serious. Therefore, it is very necessary to extinguish it in time when a fire breaks out in a residential building. [0003] At present, fire-fighting equipment is often equipped in residential buildings, such as fire hydrants, fire extinguishers, and smoke alarms with automatic sprinkler functions. In the initial stage of an indoor fire, nearby residents can extinguish the fire, but if a fire occurs on the outer wall of a high-rise building, Or when an indoor fire causes an exterior wall fire, the fire on the exterior wall is relatively fierce, and the efficiency of only using fire extinguishers or fire hydrants to extinguish ...

Problems solved by technology

[0003] At present, fire-fighting equipment is often equipped in residential buildings, such as fire hydrants, fire extinguishers, and smoke alarms with automatic sprinkler functions. In the initial stage of an indoor fire, nearby residents can extinguish the fire, but if a fire occurs on the outer wall of a high-rise building, Or when an indoor fire causes an exterior wall fire, the fire on the exterior wall is relatively fierce, and the efficiency of only using fire extinguishers or fire hydrants to extinguish the fire is too low; while waiting for fire rescue, the fire on the exterior wall of the building may spread, causing more serious damage. loss

[0004] In addition, when the fire truck comes, the water pressure of the fire truck may be insufficient due to the distance between the high-rise part and the ground, making it difficult for the fire truck to spray and extinguish the fire in the high-rise fire area.
