Warhead of a water-based fire extinguishing bomb

Abstract

The invention discloses an acting part of a water-based fire extinguishing bomb. The acting part comprises a detonating device and a bomb body device, wherein the detonating device comprises an impact head and a head screw; an explosive jar, an electric igniting head, an external ignition line, a secondary induction coil, an igniting control printed board and an insulation mechanism are arranged in the head screw; the secondary induction coil, the igniting control printed board and the electric igniting head are connected to achieve an electric detonating manner; the bomb body device comprises a central fixing tube, a micro-explosion throwing and spreading device, and a housing of which the two ends are provided with openings; the micro-explosion throwing and spreading device comprises an inner ignition line, a limiting hose and an explosive tube; the micro-explosion throwing and spreading device is positioned in the central fixing tube; one end of the central fixing tube is fixed to the opening of a front blocking cover through a pressing screw while the other end of the central fixing tube extends into the housing. According to the acting part of the water-based fire extinguishing bomb, the micro-explosion throwing and spreading structure is adopted, so that broken pieces can fly within a short distance after explosion, and the safety can be improved; an impacting and electric detonating manner is achieved in the detonating device, so that all launched fire extinguishing bombs can be detonated and exploded; the insulation mechanism is arranged and can greatly improve the safety of the fire extinguishing bombs during a storage process.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a warhead of a water-based fire extinguishing bomb. Background technique [0002] In recent years, the frequency of fires in our country has gradually increased. In order to effectively deal with fires, solve the problem of direct confrontation between humans and fire and the casualties of firefighters during the firefighting process, many units have developed fire extinguishing bombs using military technology, adding new equipment to my country's firefighting cause. The design of the warhead directly affects the fire extinguishing effect and safety of use. Compared with dry powder, water-based fire extinguishing agent has the advantages of convenient filling, simple process, and good fire extinguishing effect, and is widely used. The water-based fire extinguishing agent is sprayed by explosion method, forming water mist, high heat absorption efficiency, and good ...

AI Technical Summary

Problems solved by technology

The water-based fire extinguishing agent is sprayed by explosion method, forming water mist, high heat absorption efficiency, and good fire extinguishing effect, but the existing fire extinguishing bomb has a single detonation mode and low reliability; there are no safety isolation measures for fire transmission, and the explosion throwing power is relatively large. There are certain security risks
