Abstract

The invention relates to an exterior wall water curtain fire-extinguishing system for high-rise buildings, which comprises a fire protection water supply sub-system, a fire protection control sub-system, an indoor fire protection sub-system, an exterior wall sensing sub-system and an exterior wall water curtain sub-system, wherein two fire protection water pumps (one is used and other one is standby) and a plurality of water pump adapters are arranged at one end of the fire protection water supply sub-system, and a valve group is arranged at the other end of the fire protection water supply sub-system; the valve group is respectively connected with the exterior wall water curtain sub-system and the indoor fire protection sub-system; the fire protection control sub-system is connected with the external wall sensing sub-system and used for controlling the exterior wall water curtain sub-system and the indoor fire protection sub-system; the exterior wall sensing sub-system comprises a sensor and a signal bus, and the signal bus is connected into the fire protection control sub-system; and the exterior wall water curtain sub-system comprises a main pipe, a trunk pipe, a plurality of branch pipes, an electromagnetic control valve and a fan-shaped spray head. The water curtain fire-extinguishing system can block a channel for leading flame of the high-rise building to spread to the outside and effectively contain the development of fire.

Description

technical field [0001] The invention relates to a fire fighting system, in particular to a water curtain fire extinguishing system for the outer wall of a high-rise building. Background technique [0002] In recent years, urban buildings have become higher and higher, and high-rise building fires are also emerging in an endless stream. On November 15, 2010, a Shanghai apartment fire killed 58 people and more than 70 were injured; on September 9, 2010, a fire broke out in two 32-story high-rise buildings in a building under construction in Changchun City, Jilin Province, causing a total of 42 people to be injured. Loss of about 6 million yuan; at 4:27 on August 9, 2010, a fire broke out in a 29-story residential building in Yuzhong District, Chongqing, causing heavy property losses to residents; at 20:00 on February 9, 2009, the North Annex Building The fire caused losses of up to 5 billion yuan. Fires in high-rise buildings have the characteristics of rising, curling, and ...
