Problems solved by technology

[0010] The fire water pressure of the automatic sprinkler system is low, which cannot meet the pressure requirements of the sprinkler system; some sprinkler systems have no voltage stabilizing equipment, which cannot meet the water pressure requirements of higher floors
[0011] The sprinkler pump is not connected to the fire-fighting power distribution line, or there is no backup pump, and some fire-fighting water sources fail to meet the water level requirements for the self-priming start-up of the sprinkler pump

Embodiment 1

[0034] Such as figure 1 As shown, the automatic fire suppression system includes:

[0035] The fire detection unit 11 detects whether a fire occurs;

[0036] The gas fire extinguishing controller unit 12, when the fire detection unit detects 11 that a fire occurs, the gas fire extinguishing controller unit 12 starts the fire extinguishing program, and controls the action of the equipment linkage unit 13, the delay unit 14 and the fire alarm display unit 15; the equipment linkage unit 13, It is used to turn off the power supply and fan on site; the delay unit 14 is set for a delay of 0 to 30 seconds and then starts the fire extinguishing unit; the fire alarm display unit 15 is used for sound and light alarm; After the time is over, start the gas fire extinguishing unit 16 to extinguish the fire.

[0037] The gas fire extinguishing unit 16 includes: a selection valve, a bottle head valve, a driving bottle and a storage bottle, etc., which are common structures for gas fire ext...

Embodiment 2

[0058] The main steps of fire extinguishing in this embodiment are the same as those in Embodiment 1. The same steps use the same numbers and will not be described again. The difference between this embodiment and Embodiment 1 is that in this embodiment, a life detection step S201 is added to the delay step. Such as figure 2 As shown, when the fire detector detects the fire, after reaching the step S102 where the gas fire extinguishing controller starts the fire extinguishing program, the gas fire extinguishing controller starts the radar life detector at the same time to detect whether there are people in the fire area. When there are people in the fire area, it will send a special signal to the fire alarm display system that there are people in the fire area, reminding the on-site staff to ask for help or evacuate the people in the fire area. At the same time, a signal should be sent to the delay unit to further extend the time for spraying the fire extinguishing agent, f...

Abstract

The invention provides an automatic fire extinguishing system and an automatic fire extinguishing method thereof. Fire extinguishing is conducted through heptafluoropropane. The automatic fire extinguishing system comprises a fire detecting unit, a gas fire extinguishing controller unit, an equipment linkage unit, a delay unit, a fire alarm displaying unit and a gas fire extinguishing unit, wherein the fire detecting unit is used for detecting whether a fire happens or not; the gas fire extinguishing controller unit is used for starting a fire extinguishing procedure after the fire detecting unit detects that the fire happens; the equipment linkage unit is used for turning off a power source and stopping a fan on site; through the delay unit, the delay time which is 0-30 s is set, and thenthe fire extinguishing unit is started; the fire alarm displaying unit is used for conducting sound-light alarm; and the gas fire extinguishing unit is started for fire extinguishing after the delaytime of the delay unit is finished. According to the automatic fire extinguishing system, the equipment linkage unit is arranged, and thus, the fan and the dangerous power source which influence the fire extinguishing effect can be stopped and turned off when the fire happens; and moreover, due to the fact that the delay unit is arranged, evacuation time can be reserved for field staff, fire extinguishing is conducted, the fire extinguishing safety is improved.

Description

technical field [0001] The invention relates to an automatic fire extinguishing system and an automatic fire extinguishing method thereof, belonging to the field of building fire protection. Background technique [0002] Building fire protection facilities refer to the general term for equipment and facilities used to prevent and extinguish building fires, such as automatic fire alarm systems, automatic sprinkler systems, and fire hydrant systems installed in buildings. Commonly used are fire automatic alarm system, automatic sprinkler system, fire hydrant system, gas fire extinguishing system, foam fire extinguishing system, dry powder fire extinguishing system, smoke prevention and exhaust system, safety evacuation system, etc. [0003] my country's building fire protection facilities legislation started relatively late, but developed rapidly. In a series of fire protection technical regulations such as the "Building Design Fire Protection Code" promulgated after 1987, it ...
