Fire extinguishing device for fire engineering

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...

[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 hidden danger of re-ignition, resulting in a secondary fire disaster
