Embodiment 1

[0029] Embodiment 1, when a fire breaks out, the device is moved to the fire extinguishing site, and then the height of the lifting plate 3 can be adjusted through the external structure, so that the nozzle 12 can be aimed at the top of the fire source, and then the nozzle 12 can spray to the fire. Water, to reduce the surface temperature of the combustibles, make it drop to below the ignition point, thereby play the effect of fire extinguishing, and the nozzles 12 can be made to all face outwards, and because the nozzles 12 are distributed in a ring, therefore, the water sprayed by the nozzles 12 A cone-shaped water mist will be formed, which can also play a certain role in blocking the toxic gas produced by combustion and the ashes in the air, preventing it from floating randomly.

[0030] At the same time, inflate the powder spraying box 9 through the inflatable assembly, then the air pressure in the powder spraying box 9 becomes larger, and the flame-retardant powder in it ...

Embodiment 2

[0042] Embodiment 2, different from Embodiment 1, is that the inflatable assembly adopts the air pump 30, by starting the air pump 30, and then inflating the powder spraying box 9 through the air delivery pipe 29, so compared with the inflatable assembly of Embodiment 1, it will make Inflation is relatively continuous and stable, but at the same time, the energy consumption will also increase accordingly, and this can make the air pressure in the powder spraying box 9 larger than that in Embodiment 1, so that the distance that the powder can be sprayed becomes farther, and then can Adapted to fight larger fires.

[0043] Further, the rotating shaft 6 is fixed with a cylinder 5 away from the outer wall of the powder spraying box 9, and the outer wall of the cylinder 5 is provided with a curved groove 25, and the piston plate 24 is fixed with a movable tube 7 near the outer wall of the cylinder 5, and the movable tube 7 is sleeved on the cylindrical surface. 5. The outer wall an...

Abstract

The fire extinguishing device comprises a base, a lifting plate capable of ascending and descending is installed at the top of the base, an inner gear ring is fixed to the top of the lifting plate through a fixing rod, a plurality of spray heads capable of spraying water are installed on the outer wall of the inner gear ring, and the spray heads are annularly distributed; a powder spraying box used for containing flame-retardant powder is fixed to the top of the lifting plate through a supporting rod, and a powder spraying opening is formed in the outer wall, close to the inner gear ring, of the powder spraying box. The powder spraying device further comprises an inflation assembly used for inflating the powder spraying box. Through cooperation of structures and dual cooperation of water and flame-retardant powder, the fire extinguishing speed and efficiency can be further improved, after the fire extinguishing agent is mixed with water, the powder can form a pasty isolation layer on the surface of a comburent, the oxygen isolation effect can be further achieved, then the comburent can be effectively prevented from being reburnt, and the fire extinguishing effect is improved. And the hidden danger of secondary fire is avoided.

Description

technical field [0001] The invention relates to the technical field of fire protection engineering, in particular to a fire extinguishing device used in fire protection engineering. Background technique [0002] Fire is one of the major disasters that most frequently and universally threaten public safety and social development. Especially in today's rapidly developing society, fires may be caused by various factors. If it is a small fire, the fire can be extinguished manually, but if there is a fire in some factories or workshops, firefighting is required. Personnel extinguished the fire at the scene to prevent other accidents from happening. [0003] However, most of the existing common fire extinguishing devices use water spray cooling to extinguish the fire, reducing the surface temperature of the burning object below the ignition point, so as to achieve the purpose of extinguishing the fire. However, by spraying water to cool the fire, the burning object There is a hi...
