AI Technical Summary

Technical Problem

Existing forest fire-fighting burning tools suffer from poor safety, weak terrain adaptability, low operational efficiency, and insufficient reliability. In particular, they are difficult to effectively implement large-area or long-distance firebreaks in complex terrain and harsh environments.

Method used

A self-reaction system of potassium permanganate powder and ethylene glycol-water mixture is used to mix with liquid reagents by mechanical injection to achieve delayed ignition of 20s to 60s. Combined with a liquid bottle for separate storage, an injection device and a launching device, a remote projection ignition system is constructed.

Benefits of technology

It achieves safe delayed ignition without external fire source, improves operational safety and reliability, adapts to complex terrain, enhances operational efficiency and coverage, and is suitable for the rapid formation of large-scale forest firebreaks.

Abstract

The invention relates to a combustion ball of a remote projection type ignition device in forest and an ignition system, and the combustion ball comprises a plastic ball shell made of high impact polystyrene; the potassium permanganate powder is packaged in the spherical shell; the liquid reagent is mixed with the potassium permanganate in a mechanical injection manner during use; wherein the liquid reagent is a mixture of ethylene glycol and water, and delayed ignition time of 20-60 seconds is generated after the potassium permanganate powder and the liquid reagent are mixed by regulating and controlling the mass of the potassium permanganate powder and the composition and the volume of the liquid reagent. The remote projection type ignition system comprises the combustion ball and a liquid bottle used for storing the liquid reagent. The injection device is used for injecting the liquid reagent into the combustion ball from the liquid bottle; and the launching device is used for projecting the combustion ball injected with the liquid reagent to a target area. The device has the effects of being high in safety, high in operation efficiency, stable and reliable.
