Fire extinguishing bomb and launching device thereof

Abstract

The invention discloses a fire extinguishing bomb. The bomb comprises a first container, a second container and a fixing base, wherein the outer wall of the fixing base is in threaded connection withthe inner wall of the first container, moreover, the second container is sleeved with the first container, and a third container is further sleeved with the second container; a plurality of round holes are formed in the surface of the third container, and puncture bulges are arranged at the gaps of the round holes; the invention further provides a launching device, the launching device comprises alaunching cavity, a material feeding chamber, a first spring, a first material passage and a second material passage, wherein the upper end of the launching cavity is connected with the material feeding chamber through the first material passage, an air pressure cylinder is arranged on the inner wall of the right end of the launching cavity, moreover, the tail end of the air pressure cylinder isconnected with one end of the first spring, and the other end of the first spring is provided with a first permanent magnet; and a first electromagnet which is opposite to the magnetic pole of an permanent magnet is arranged at the tail end of a piston rod, a second electromagnet is arranged on the inner wall of the upper end of the second material channel, and the second electromagnet is connected with the permanent magnet through a second spring. According to the bomb and the device, the structure is simple, operation is convenient, and application range is wide.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a fire extinguishing bomb and a launching device thereof. 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 loss to life...

[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
