Embodiment Construction

[0038] A high-rise fire extinguishing bomb for short-distance and precise powder spraying, including a powder spray cover 1, a film support ring 2, a plastic film 3, a film pressure ring 4, a film rupture steel needle 5, an electronic lock 6, a launch tube 7, and a powder tube 8. Guide tube 9, dry powder fire extinguishing agent 10, powder pushing plate 11, hot aerosol 12, connector 13, delay agent 14, delay igniter 15, combustion chamber shell 16, low temperature gas generating agent 17, tablet 18, rear Cover 19 and igniter 20. Wherein: the powder cylinder 8 is located in the launch cylinder 7, and the dry powder fire extinguishing agent 10 is placed in the powder cylinder. The upper end of the powder cylinder is fixedly connected with the powder spraying cap 1 through threads. A sealing piece is placed on the upper end surface of the powder cylinder, and after the powder spraying cover is fixedly connected with the powder cylinder, the sealing piece is pressed tightly on th...

Abstract

A high-rise fire extinguishing bomb for spraying powder. The powder cylinder containing the dry powder fire extinguishing agent is located in the launching tube; the connecting part is located in the launching tube; the filling cavity of the hot aerosol is located in the lower end surface of the powder pushing plate and the connecting part. between the ends. There is an axially protruding delayed igniter sleeve at the center of the lower end face of the connecting piece. One end of the delayed medicament passes through the inner hole of the delayed igniter and enters the guide tube. The guide tube is located inside the powder cartridge. The invention solves the problems of high-temperature tail flame and high speed of the existing fire extinguishing bombs, and the short-distance delivery improves the hit accuracy of the fire extinguishing bombs, and the coverage of the fire extinguishing agent increases by at least 30%; it reduces the impact force of the fire extinguishing bombs on buildings potential for harm.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a high-rise fire extinguishing bomb that accurately delivers spherical powder spraying at a short distance of 10m to 15m. Background technique [0002] With the rapid increase in the number of high-rise and super high-rise buildings, the problem of fire fighting in high-rise buildings is becoming increasingly serious. For these high-rise buildings that cannot be taken into account by fire ladders, fire extinguishing operations are generally carried out by firing fire extinguishing bombs at medium and long distances. Existing fire extinguishing bomb products. [0003] In the patent with the notification number CN206867541U, a high-rise building window fire extinguishing bomb is disclosed. The distance between the warhead and the propulsion part is adjusted by adjusting the barrel, or the length of the blasting head is adjusted to adjust the length of th...
