Spontaneous combustion type fire extinguishing bullet for fire protection

Abstract

The invention discloses a spontaneous combustion type fire extinguishing bullet for fire protection. The fire extinguishing bullet comprises a sealing cover, external containers and an internal container, wherein the sealing cover adopts a sleeve structure and is divided into an inner ring and an outer ring; threads are arranged on the inner walls of both the inner ring and the outer ring of the sealing cover; a sliding chute is formed in the inner wall of the top end of the external container I; a puncture sharp knife is arranged at the top end of the interior of the external container II; asolution and powdery substance which produces chemical reaction with the solution and produces carbon dioxide are correspondingly contained in the internal container and the external container II respectively; a sealing ring I is arranged at the tail end of the external container II; the sealing ring I adopts a convex structure; the side wall of the upper part of the sealing ring I is fixed on theouter wall of the internal container through a plastic screw. The fire extinguishing bullet is simple in designed structure, easy to carry, easy to operate and high in safety index, cannot cause damage to human body, buildings and other furniture and equipment during explosion, and only achieves extinguishment effect on fire sources.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a self-igniting fire extinguishing bomb for fire fighting. Background technique [0002] The fire-fighting appliances currently used for fire extinguishing are mainly fire trucks and dry powder fire extinguishers. Fire trucks use high-pressure water guns to extinguish fires, which are only suitable for fire extinguishing in areas with convenient transportation and water resources; dry powder fire extinguishers use dry powder to generate a large amount of carbon dioxide foam to extinguish fires. Fire, only suitable for small-scale fires or fires at the beginning, both are powerless for large-scale fires in remote areas with poor transportation, because there is no suitable remote fire fighting equipment, so the fire is fierce in remote areas or forest areas, and there is no water source Insufficient, the fire often lasts several months to put out, and also caused serious los...

Problems solved by technology

[0003] However, the existing fire extinguishing bombs need to be ignited artificially. If the operation is improper, it will cause failure to detonate, lose its due effect, and even hurt people; Some fire extinguishing bombs made of ordinary ABC dry powder not only have low fire extinguishing efficiency, but also have inherent defects such as moisture absorption and agglomeration.
