It should be noted that, the controller 160 may be a PLC controller with model number S7-200; here, the flame detector 150 is also called a photosensitive fire detector, which is a fire detector for responding to the optical characteristics of a fire, that is, detecting the light intensity of flame combustion and the flicker frequency of the flame, and the flame detectors 150 used are three types according to the optical characteristics of the flame: one is an ultraviolet detector sensitive to the shorter wavelength ultraviolet radiation in the flame; the other is an infrared detector sensitive to longer wavelength infrared radiation in the flame; the third is an ultraviolet/infrared hybrid detector for simultaneously detecting ultraviolet rays with shorter wavelength and infrared rays with longer wavelength in the flame, and the embodiment adopts the ultraviolet/infrared hybrid detector.

As an alternative embodiment, a protective shell 170 is arranged on the top of the connecting plate 110, and the speed reducer 121 and the driving motor 122 are both located in the protective shell 170, so that the speed reducer 121 and the driving motor 122 are prevented from being directly exposed to the outside and damaged by the influence of a fire scene, and a good protection effect is achieved.

As an alternative embodiment, the device further comprises a mounting mechanism 180, wherein a plurality of sets of telescopic mechanisms 190 are connected to the bottom of the mounting mechanism 180, and the telescopic mechanisms 190 are connected to the top of the connecting plate 110.

An auxiliary rupture disk 146 is connected to one end of the electric detonator 145 close to the release chamber 142, and a main rupture disk 147 is arranged between the filling chamber 143 and the release chamber 142.

In the present embodiment, when the electric detonator 145 receives the execution signal transmitted from the controller 160, the electric detonator 145 is detonated to burst the auxiliary rupture disk 146, the pressure generated thereby induces the main rupture disk 147 to burst, and the explosion suppressant is ejected from the release hole 144 under the high-pressure thrust, thereby suppressing the fire source and playing an explosion-proof role.

As an alternative embodiment, the explosion suppressant is any one of ammonium dihydrogen phosphate, sodium bicarbonate, potassium bicarbonate, sodium chloride, fluoride, water, inert gas and alkyl halide.

Among them, the explosion suppression powders such as ammonium dihydrogen phosphate, sodium bicarbonate, potassium bicarbonate, etc. have good explosion suppression effect, and are most commonly used, and the main functions of the explosion suppression powders are to destroy chain reaction (chemical effect), reduce oxygen concentration (chemical effect) and absorb heat to reduce temperature (physical effect).

As water is harmless to human bodies and is cheap, a large amount of documents research the explosion suppression effect of water, the explosion suppression effect of water is not superior to that of chemical explosion suppression powder (ammonium hydrogen phosphate and the like), but the explosion suppression effect is also good, and the explosion suppression effect is as follows:

(1) destructive effect of chain reaction

The extremely fine water mist droplets can be combined with free radicals in the chain reaction to destroy the chain reaction;

(2) wave absorption effect

The shock wave is when in contact with the water droplet. Larger water droplets are broken into smaller water droplets, and the smaller water droplets are vaporized into water vapor to absorb energy, so that the shock wave energy is attenuated;

(3) inerting effect

The oxygen concentration is greatly reduced when the water drops are vaporized into water vapor;

(4) heat absorption effect

When the flame front (reaction zone) is contacted with water drops, the vaporization heat absorption of the water drops can reduce the temperature of the reaction zone, thereby reducing the propagation speed of flame and even extinguishing the flame;

the chain reaction destructive effect of water can be improved by adding the explosion suppression powder in the water.

However, water is prone to freezing at low temperatures and requires heating systems to prevent freezing in some seasons.

In addition, haloalkane (commonly known as halon) is a very good explosion suppressant, and previous studies showed that CF3Br had a chemical effect of 88% and a physical effect of 12%, while sodium bicarbonate had a physical effect of 47%.
