Novel fire extinguishing device and preparation method thereof

Abstract

The novel fire extinguishing device comprises a box body, a reaction chamber is arranged in the box body, storage boxes are arranged on the inner walls of the left side and the right side of the reaction chamber, adding openings are formed in the opposite sides of the two storage boxes, through openings are formed in the lower ends of the two storage boxes, and an annular cavity is formed in the box body; the annular cavity is located above the reaction chamber, the top space of the reaction chamber is communicated with the bottom space of the annular cavity through a vertical pipe, and the annular cavity is communicated with the outside through a plurality of arc-shaped pipes; rectangular grooves are formed in the inner walls of the opposite sides of the two through openings. According to the device, carbon dioxide is used for replacing dry powder for fire extinguishing, meanwhile, in the fire extinguishing process, the box body can be in a rotating state, so that carbon dioxide gas and water can be evenly sprayed around, fire extinguishing can be better conducted aiming at a fire source, gas can be blown to an indicator light during fire extinguishing, and the fire extinguishing effect is better. And recovery by firefighters after fire extinguishment is facilitated.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to a novel fire extinguishing device and a preparation method. Background technique [0002] In the event of a fire, due to the relatively narrow space in some areas, when the fire is large, it is not conducive to the passage of firefighters. At this time, firefighters usually throw some devices that can be thrown into the fire field and use the way of explosion to generate fire. Dry powder is used to achieve the purpose of fire extinguishing, but the existing throwing type fire extinguishing device still has the following problems in use: [0003] When this kind of dry powder fire extinguishing device is thrown into the fire, it uses the impact generated by the explosion to blow out the dry powder. Due to the large impact force generated by the explosion, part of the dry powder may not be able to accurately cover the fire point, resulting in fire. The coverage o...

Problems solved by technology

[0003] When this kind of dry powder fire extinguishing device is thrown into the fire, it uses the impact generated by the explosion to blow out the dry powder. Due to the large impact force generated by the explosion, part of the dry powder may not be able to accurately cover the fire point, resulting in fire. The coverage of the dry powder at the location is small, and the fire extinguishing effect is not good. After each use, the device cannot be recycled because it has exploded, which will cause a certain waste of resources. Therefore, how to solve this problem reasonably is what we need need to consider
