AI Technical Summary

Problems solved by technology

Ordinary central squibs are long and thin in the longitudinal direction, and can only disperse the fire extinguishing agent into a thin ring or dish shape, so that the upper and lower fire fields of the forest fire extinguishing bomb cannot be completely submerged by the fire extinguishing agent
Because the ideal dispersion uniformity cannot be obtained, resulting in unsatisfactory fire extinguishing effect and waste of fire extinguishing agent

Embodiment Construction

[0010] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0011] combine Figure 1~2 , which mainly includes an induction detonating device 1, a positioning connecting conduit 2, a longitudinal squib 3, a horizontal squib 4, and a spatial cross-shaped squib connecting sleeve 5. The longitudinal squib 3 and the transverse squib 4 are affixed together through a space cross-shaped squib coupling sleeve 5 .

[0012] When the forest fire extinguishing aerial bomb lands inside the canopy fire scene or other fire scenes, the induction detonating device 1 detonates.

[0013] The induction detonating device 1 is connected with the longitudinal detonator 3 through the positioning connecting conduit 2, and its main function is to transfer the explosion energy of the induction detonating device 1 to the longitudinal detonator 3 and the horizontal detonator 4 at high speed, so that the longitudinal detonator 3 and the horizontal det...

Abstract

The invention aims to provide a spatial cross central explosion tube comprising a sympathetic detonation device, a positioning connecting conduit, a longitudinal explosion tube, a transverse explosion tube and a connecting sleeve, wherein the sympathetic detonation device is connected to the longitudinal explosion tube through the positioning connecting conduit; and the longitudinal explosion tube is connected to the transverse explosion tube through the connecting sleeve. According to the invention, an ultrathin dry powder extinguishing agent can disperse into ellipsoids so as to evenly disperse inside a fire scene at a flooding concentration; and therefore a lot of extinguishing agents can be saved and the fire extinguishing efficiency of a forest fire fighting aerial bomb can be improved.

Description

technical field [0001] The invention relates to a fire extinguishing device in the field of fire fighting. Background technique [0002] Forest fire is a serious worldwide natural disaster, which has caused immeasurable losses to human resources and the environment. It can bring about soil erosion, land desertification, burn down forest plant resources, endanger wild animals, cause air pollution, and threaten the safety of people's lives and property. At the scene of a forest fire, the first fires are often dwarf bushes and ground vegetation, which are called ground fires. When the ground fire is accompanied by strong winds, or encounters vines and low-hanging branches on the trunk, the fire will rise to the crown of the tree and become a crown fire. The fire takes advantage of the wind, and the wind helps the fire to spread and spread extremely quickly. The forest fires in China's Greater Khingan Mountains in 1987, California in the United States, and Australia in 2008 we...
