Description

Large forest fires extinguishing extinguisher bullet detonation device}

The present invention relates to a fire extinguishing device for large-scale fire extinguishing, more specifically, to form a fire extinguishing coal containing powder extinguishing agent as an eco-friendly material to prevent environmental pollution, and to easily control the detonation device to be accommodated in the extinguisher. The present invention relates to a large-scale fire extinguishing grenade detonator capable of quickly extinguishing a fire by dropping the powder extinguishing agent from a helicopter in the air.

In general, a fire extinguisher (消火器, fire extinguisher) refers to a mechanism that can extinguish the fire by using the cooling or air blocking effect of the extinguishing agent in the very early stages of the fire. There are several types depending on the drugs or mechanisms used, but currently used fire extinguishers are foam fire extinguishers, powder fire extinguishers, halon fire extinguishers, and carbon dioxide fire extinguishers.

The fire extinguisher includes a container in the form of a pressure-resistant container filled with a fire extinguishing agent, a valve installed at an upper inlet of the container, and a tube-shaped nozzle part connected to the valve. The valve is equipped with a pressure gauge and a handle. It is common for the nozzle part to include a flexible hose so that it can be sprayed accurately towards the fire point.

At this time, the type of extinguishing agent used may vary depending on the nature of the ignition material or the place where it is used. Recently, fire extinguishers using eco-friendly drugs have been proposed for use in civilian or military applications.

However, a conventional fire extinguisher has a problem in that a fire extinguisher or a medicine is contained inside a fire extinguisher made of a heavy metal material, and there is a problem that a fire extinguisher must be grasped and moved when a fire or forest fire occurs. There is a problem that the environment is polluted because it is difficult to recycle the fire extinguisher.

In order to solve this problem, a technology has been developed in which fire extinguishers of eco-friendly materials containing fire extinguishing powder are thrown through a helicopter and blown up in the air, so that fire extinguishing powder is scattered in the air to extinguish forest fires.

The above-described invention means the background art in the technical field to which the present invention belongs, and does not mean the prior art.
