Description

Fire Extinguisher {GRENADE FOR FOREST FIRE EXTINGUISH}

The present invention relates to a fire extinguisher for fire extinguishing. In particular, when a forest fire occurs, the control unit adjusts the rudder so that it falls close to the flame area so that it is possible to control the direction of the fall so that it can be precisely hit above the center of the flame. , as heat is sensed after being hit, the fire extinguishing liquid is automatically sprayed to extinguish a wildfire, and after use is completed, the fire extinguisher is easily recovered using GPS. By allowing the sprayed angle to be sprayed by distance, it relates to a fire extinguishing grenade whose structure is improved to enable extinguishing of a wide area.

In general, when a forest fire occurred, firefighting personnel had to be mobilized to go directly to the forest fire site, and the mobilized firefighters used conventional firefighting equipment such as rakes, fire rakes, sickles, hoes, shovels, and back pack pumps to extinguish forest fires.

However, in the current rural population, it is difficult to mobilize the fire-fighting manpower due to the aging and the aging of the women, and it is difficult to suppress the fire with the current conventional fire-fighting equipment at the beginning, and the initial fire-fighting work is impossible.

With the existing equipment, it was difficult to suppress the buzzword at the beginning and it was impossible to extinguish the fire in the first place.

In addition, during the dry season, spring and autumn, when forest fires occur most frequently, when there are many tourists, the mobilization of public officials for forest fire prevention, monitoring, and firefighting work wastes time as well as greatly hinders normal administrative performance.

And, there was a problem in that it was difficult to extinguish the fire during the time it takes for the extinguishing agent to reach the combustion area and the wildfire spreads over a wide area, and cases in which the damage becomes greater sometimes occur.

In addition, in the case of wildfires in rugged mountainous areas during strong winds and wildfires at night, it is not possible to use firefighting personnel or helicopters, and especially in the case of wildfires in the military shooting range and minefields, the firefighting work is helpless, so the damage is further increased.

Since these wildfires move with the wind and destroy forests, the damage is very serious if not quickly extinguished in the early stages.

However, it is inconvenient for firefighters to carry heavy fire suppression equipment to the fire site and then extinguish the fire in order to directly extinguish the forest fire because it is impossible for firefighters to enter the fire site where a forest fire occurs.

In addition, when the firefighters who were extinguishing the fire work under the ridge, there is a problem in that the flames come down as if encircling them and cause serious casualties to the firefighters who were extinguishing the fire.

In order to solve this problem, fire-fighting helicopters that spray fire extinguishing agents in the air have been developed, but in areas with rough mountains and strong winds, fire extinguishing agents sprayed from the air cannot reach the fire site properly, and the rise caused by forest fires There is a problem that flames and smoke block the view of the firefighting helicopter by the airflow.

Moreover, when water used in a large fire is sprayed in the air, there is a serious problem in that the sight of the firefighting helicopter cannot be secured due to a large amount of water vapor generated by heating the sprayed water.
