Abstract

The invention provides a pneumatic emission-type forest extinguishing cannonball, which mainly comprises a ballistic cap, a fuze, a cylindrical shell, a fire-extinguishing agent, a central nonel tube, an umbrella cabin shell, a brake parachute and an umbrella throwing disengagement structure, wherein, the ballistic cap is connected with the front end of the cylindrical shell; the cylindrical shell is connected with the umbrella cabin shell through a connecting plate; the fuze is fixed at the front end of the cylindrical shell; the central nonel tube is fixed in the cylindrical shell and is connected with the fuze through a wire; the umbrella cabin shell is provided with the umbrella throwing disengagement structure and the brake parachute; the fire-extinguishing agent is filled in the cylindrical shell. The pneumatic emission-type forest extinguishing cannonball of the invention can scatter the fire-extinguishing agent and can achieve the optimal extinguishing effect.

Description

Technical field [0001] The invention relates to a fire-fighting equipment, in particular to a pneumatically launched forest fire-extinguishing projectile driven by compressed air. Background technique [0002] Large-scale forest fires can cause serious damage to human property and the ecological environment, and have now attracted great attention from all countries. According to the burning characteristics of forest fires, they can be divided into three types: underground fire, surface fire and canopy fire. Among them, canopy fire is the most difficult to put out. Under the action of strong wind, it is easy to form wild fire or produce "flying fire" or "fire". Tornadoes and firestorms are one of the main reasons for accelerating the spread of forest fires. [0003] As a powerful fire fighting weapon, fire extinguishing bombs have been recognized by the firefighting community. There are many known types of forest fire extinguishing bombs, including hand-disposable fire extinguishi...
