Description

[FIRE EXTINGUISHER USING DRONE]

TECHNICAL FIELD The present invention relates to an extinguishing apparatus, and more particularly, to an extinguishing apparatus using a drone.

Generally, fire extinguishers are used to turn off the fire. The fire extinguisher is filled with chemicals that can turn off the fire. In case of fire, remove the safety pin by turning the hose direction to fire, and when the lever is pulled, the chemical is sprayed Fire extinguishers, powder fire extinguishers, foam fire extinguishers, etc. have been manufactured depending on the type and form of fire extinguishing agent.

However, since a general fire extinguisher must be manually operated by a user, there is a problem that the fire extinguisher can not be used properly when the fire can not be detected or when fire detection or fire suppression is difficult.

To this end, Korean Patent No. 10-1209541 (Patent Document 1) discloses a fire extinguisher having an enclosed container in which a fire extinguishing agent is contained, wherein the enclosed container is made of a plate material having an upper portion and a lower portion, The core is inserted to mechanically fix the upper plate and the lower plate to each other, and the space between the upper plate and the lower plate has a communicating space; The hermetically sealed container may further include a medicine spraying part for spraying the extinguishing agent and a medicine injecting part for injecting the extinguishing agent (fire extinguishing gas of HFCs series) to the fire occurrence part, Wherein the opening is closed by a gas injection nozzle plug, and when heat is transferred to the gas injection nozzle plug by the occurrence of a fire, the gas injection nozzle plug opens the opening to spray the extinguishing agent, Type fire extinguisher.

However, since the panel fire extinguisher such as the patent document 1 has a special form in which the enclosed container is composed of the upper / lower plates and the core and has the space communicated between the upper and lower plates, the manufacturing method is difficult and expensive Which is uneconomical.

Further, since the upper and lower plates are provided with openings for injecting medicines and gas, there is a problem that the gas may leak if left for a long time.

In addition, there is a place where firefighters can not enter directly in the case of a fire in a building or a complex structure. In recent years, there have been many cases where high-risk tasks have been replaced by special tasks of robots. However, these robots and special devices have not yet been utilized properly.
