Description

Drone destroying glass at the scene of a fire

The present invention relates to a drone for striking glass in a fire zone that destroys glass so that the drone can enter a place where a fire has occurred.

In general, when a fire occurs in a high area such as a high-rise building, the fire water is directly put into the fire area by using a fire truck equipped with an elevated ladder to extinguish the fire. In this case, fire trucks should arrive promptly in the fire area, but due to the recent increase in automobiles, fire trucks often do not arrive promptly, so the golden time for extinguishing the fire has been missed.

In addition, even if the fire truck arrives at the fire area quickly, it is still not easy for firefighters to reach the high-rise fire site by using a ladder due to the deterioration of wind or weather conditions, and it takes a lot of time to climb to the high-rise floor, so it is also difficult to extinguish the fire. Missing the golden time, there was a problem that not only property damage but also human casualties increased.

In order to solve this problem, a drone for firefighting has been recently used. Most of the firefighting drones extinguish fires using fire extinguishers, fire extinguishers, and drop bombs. However, when a building is equipped with a glass window, it is difficult to drop fire munitions, fire fire munitions, or use a fire extinguisher. Accordingly, there is a demand for the development of a drone for destroying a glass window when a glass window provided with a glass window in a building is not destroyed.

As disclosed in Republic of Korea Patent Publication No. 10-2190643 "Fighting Tempered Glass Destroying Drone", the glass window is destroyed by an electric hammer, unlike the conventional firefighting drone that causes the glass window to be destroyed by firing an open bullet. However, while the adsorption part of the drone was attached to the window, the window was destroyed by the vibration of the electric hammer, causing the drone to shake or fall, causing damage.

In addition, the drone strikes the central point where the strength of the glass window is weakest and should be destroyed easily in a short time. In addition, the fire extinguishing work could not be carried out immediately because the fire extinguishing liquid could not be sprayed immediately after entering the fire zone at the same time as the glass was broken.
