Spontaneous-combustion type fire extinguishing bullet for firefighting and launching device thereof

Abstract

The invention discloses a spontaneous-combustion type fire extinguishing bullet for firefighting and further discloses a launching device of the fire extinguishing bullet. The spontaneous-combustion type fire extinguishing bullet comprises an opening sealing cover, an external container and an internal container; and threads are arranged on the inner walls of both the inner circle and the outer circle of the opening sealing cover correspondingly, a puncturing sharp knife is arranged at the top end in a second external container body, and the upper side wall of a first sealing ring is fixed tothe outer wall of the internal container through plastic screws. The launching device comprises a launching cavity, a material putting chamber, a first spring, a first material channel and a second material channel; and the upper end of the launching cavity is connected with the material putting chamber through the first material channel, a first electromagnet opposite to a first permanent magnetin magnetic pole is arranged at the tail end of a piston rod, and a second electromagnet is arranged on the inner wall of the upper end of the second material channel. The spontaneous-combustion typefire extinguishing bullet and the launching device thereof are high in safety factor and convenient to carry and are not limited by the geographical location and water sources, a large quantity of human resources can be saved, and ash is prevented from combusting again under the condition that the normal atmosphere is restored.

Description

technical field [0001] The invention relates to the field of fire fighting, in particular to a self-igniting fire extinguishing bomb and a launching device thereof 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 al...

[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 for several months to be extinguished, and also caused serious losses to life and property

Therefore, fire extinguishing bombs are widely used, but the existing fire extinguishing bombs not only have low fire extinguishing efficiency, but also need to be ignited artificially, and safety accidents will occur if improper operation
