Fire fighting system

Abstract

The invention relates to the technical field of fire fighting, in particular to a fire fighting system which comprises a fire detector, a spraying device, a ventilation assembly arranged along a stairway and fire-proof rolling curtains arranged at stair openings of floors. The spraying device comprises a water supply pipeline, a driving part, a guide pipe, a fire point identifier and a first sprayhead arranged on the guide pipe. The guide pipe is arranged in a hoisting mode and rotatably arranged on the water supply pipeline, the guide pipe is of a bent structure for enabling the first sprayhead to be obliquely downward, the driving part drives the guide pipe to rotate according to the fire point position information sent by the fire point identifier so as to enable the first spray headto face the fire point position, the ventilation assembly comprises a fan, a ventilation pipe extending along a stair handrail and a carbon monoxide sensor, the ventilation pipe is provided with a plurality of air outlets, and the fan is started according to the carbon monoxide concentration standard exceeding information sent by the carbon monoxide sensor so as to convey air into the stairway andreduce the carbon monoxide concentration in the stairway.

Description

technical field [0001] The present application generally relates to the technical field of fire protection, and in particular, relates to a fire protection system. Background technique [0002] The fire alarm system is generally composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices. It is transmitted to the fire alarm controller so that people can find the fire in time, and it is generally an independent sensor and alarm system. [0003] At present, most of the fire protection systems in buildings are equipped with fixed nozzles. The nozzles cannot locate the fire point to extinguish the fire by spraying. During the escape process, the escape personnel are often unable to escape due to problems such as high temperature in the stairs and high concentration of carbon monoxide, thus missing the fire. Escape opportunities, and stairs often become fire "chimneys", promoting the spread of fire. Contents of the invention ...
