Delayed explosion fire extinguishing bomb

Abstract

The invention discloses a delayed explosion fire extinguishing bomb which includes a bomb body, an end cover and an inner liner. The inner liner is arranged inside the bomb body in an inserting manner, and the inner liner is internally provided with explosives. The end cover is arranged at the end of the bomb body, and the end cover is internally equipped with a delayed detonation device which iselectrically connected with the explosive. The delayed explosion fire extinguishing bomb has the advantages of large coverage area, high fire extinguishing efficiency, safety and effectiveness, easy degradation, no secondary pollution, and delayed explosion; the delayed detonation effect is realized through a PCB board, the fire extinguishing bomb is released at a specific height, the fire extinguishing bomb is exploded at a preset height through a delayed detonation function so as to maximize the coverage area, and the fire extinguishing effect is improved.

Description

Technical field: [0001] The invention relates to the technical field of fire-fighting unmanned aerial vehicle equipment, and more specifically relates to a delayed explosion fire extinguishing bomb. Background technique: [0002] The application of drone technology in the field of firefighting is becoming more and more extensive. It is a common method of firefighting that drones fly to the sky above the fire point to release fire bombs. At present, the common fire extinguishing bombs are all triggered by vibration, that is, after the fire extinguishing bomb falls to the ignition point and receives the vibration, the explosive is detonated by an electronic or fire primer. This method has obvious disadvantages. First, it is low in safety. During the transportation and installation of the fire extinguishing bomb, it is easy to accidentally explode due to the vibration caused by improper operation, resulting in a safety accident; secondly, the fire extinguishing coverage is smal...

AI Technical Summary

Problems solved by technology

This method has obvious disadvantages. First, it is low in safety. During the transportation and installation of the fire extinguishing bomb, it is easy to accidentally explode due to the vibration caused by improper operation, resulting in a safety accident; secondly, the fire extinguishing coverage is small. When the ground explodes, the range that the fire extinguishing agent in the fire extinguishing bomb can cover is limited, and the maximum coverage area cannot be reached, which affects the fire extinguishing efficiency; then after the fire extinguishing bomb explodes, the spraying direction of the fire extinguishing agent is uncontrollable, due to the The production materials lead to the flying fragments of the projectile after the explosion affect the spraying direction and distance of the fire extinguishing agent, affecting the fire extinguishing effect; finally, the materials for making fire extinguishing bombs are all made of plastic, which is non-degradable or difficult to degrade, causing secondary pollution to the environment
