Fire-extinguishing grenade 120 and launcher used with same

Abstract

The invention belongs to the technical field of fire extinguishing equipment, in particular to a fire-extinguishing grenade 120 and a launcher used with the same, which are used for solving the problems that existing forest fire-fighting grenades are single in application range and not powerful enough and launchers for the existing forest fire-fighting grenades are unable to meet the modern fire extinguishing requirements. The caliber of a bullet of the fire-extinguishing grenade 120 is 120mm, and a ventilating bourrelet and a bourrelet of the fire-extinguishing grenade 120 are 120mm in largest outer diameter. A plurality of vent grooves are evenly and axially distributed on the outer circular surface of the ventilating bourrelet. A plurality of belts are symmetrically disposed on the outer circular surface of a belt block, each belt has a twining angle of 6 DEG and 24''. A powder chamber is in a concave chamber structure. The launcher comprises a body pipe connected with the tail of a mortar shell 60 through a connector, the body pipe is 120mm in inner diameter, and rifling grooves corresponding to the belt block are symmetrically reserved in the body pipe. The fire-extinguishing grenade 120 and the launcher used with the same have the advantages that the method of launching the grenade as launching the mortar shell is realized, fire extinguishing methods are expanded, and the fire-extinguishing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing equipment, and in particular relates to a 120 grenade fire extinguishing bomb and its supporting launcher. Background technique [0002] Fire extinguishing plays an important role in the world economy. The direct and indirect economic losses caused by forest fires, grassland fires, oil tank fires and high-rise fires to our country and human society every year are inestimable. [0003] At present, mortars are commonly used to extinguish fires. What they use are fire extinguishing bombs designed through mortar modification. Due to their structural limitations, the installed fire extinguishing dose is small, which cannot effectively extinguish the fire. Secondly, due to the long rod tail structure, the use of There are more solid wastes in the end, wasting resources and polluting the environment. And if simply adopt the grenade-loaded fire extinguishing agent to extinguish the fire, becau...

Problems solved by technology

[0004] In order to solve the problems that the existing forest fire extinguishing bomb has a single range of use, its power is not strong enough, and the launching device cannot meet the requirements of modern fire extinguishing, it provides a 120 grenade fire extinguishing bomb and its supporting launcher, which can implement ground explosion and air explosion to extinguish the forest ground , canopy fires, grassland fires, oil tank fires and high-rise fires, etc., so as to achieve long-distance sealing and control, suppress and extinguish fires; solve the problem of being unable to extinguish fires due to high altitude, far water sources, and inaccessible personnel
