Description

Fire extinguishing apparatus for initial fire suppression in buildings The present invention relates to a firefighting device for the initial suppression of a building fire, and more specifically, to a firefighting device for the initial suppression of a building fire that allows a water supply pipe to penetrate into the interior of a fire extinguishing box formed on the ceiling and side wall of each space partitioned by a wall inside the building, and allows a sprinkler guide pipe and a sprinkler to move sequentially by the supply pressure of firefighting water flowing through a water supply shut-off valve that operates when a fire occurs, thereby separating a cover connected to cover one open side of the fire extinguishing box from the fire extinguishing box, and simultaneously spraying firefighting water through a sprinkler that is provided to extend further than the sprinkler guide pipe, so as to suppress the fire at an early stage. Generally, fire hydrants installed indoors are installed on the outer walls of each floor of a building to notify people inside the building of a fire when a fire occurs, and contain a fire hose that can spray water to the point where the fire started inside the fire indicator and suppression box. Since fire hydrants cannot automatically notify of a fire, there is a problem in that people inside the building where the fire occurred are unable to recognize the fire as quickly as possible. In other words, the fire hydrant activates fire alarms, such as emergency bells and alarms, only when the fire notification button is pressed by a user, thereby notifying people inside the building that a fire has occurred. Since fire hydrants are used to manually notify of a fire, not only is rapid evacuation not possible, but fire alarms can only be used to report the fire to government agencies responsible for fire suppression and post-fire handling, such as fire departments, which prevents rapid fire suppression and post-fire handling. In addition, fire hydrants that receive power from an external source operate using an emergency power battery when the external power supply is cut off due to an emergency situation such as a fire. However, the emergency power battery is a 12V battery, and since the capacity for each operation is small, it is difficult to normally execute operations related to fire suppression. In the initial fire suppression device for buildings disclosed in Registered Patent No. 2346594 (December 29, 2021), a configuration was proposed in which, upon the occurrence of a fire, the location information of the fire is immediately verified, a breaking part is moved to the verified fire location to break the glass, and then firefighting water is immediately sprayed to the fire location. In other words, when the location of a fire is detected by fire detectors, a breaking part installed on a fixed bar at the end of a rope equipped to be wound or unwound by a winder is moved to the location of the fire, and the glass is broken by this breaking part, and fire extinguishing water is sprayed to the location of the fire by a fire extinguishing water supply unit provided on the roof. However, in the aforementioned conventional technology, since the rope and supply tube unwound from the winder are supplied from the rooftop, if the fire spreads to a height higher than the unwound height of the rope and supply tube, the rope and supply tube are affected by the fire, and the fire-damaging part and fire extinguishing water supply unit are formed in only one place, so there is a problem that the range in which the fire can be extinguished is extremely narrow.
