Claims

[Scope of utility model registration request]

This is an automatic fire extinguishing system that automatically activates a fire extinguisher based on a signal from a fire detector, and uses pressurized gas filled in the extinguishing agent container in advance to spray out the extinguishing agent in the extinguishing agent container from a nozzle. The lid attached to the upper opening of the fire extinguishing agent container supports an activation rod that opens a valve built into the lid when pressed down to discharge the extinguishing agent, and a gutter-shaped trough fixed to the lid. The middle part of the lever plate is pivotably pivoted by a horizontal shaft to the handle with an open top surface, and a first spring is applied to one end of the lever plate that engages with the upper end of the activation rod in the upward direction. In an accumulating automatic fire extinguishing system, the handle is provided with a drive unit that is elastic and pushes up the other end of the lever plate based on a signal from a fire detector when a fire occurs. A through hole is formed closer to the end of this lever plate than the shaft to which the lever is pivoted, and at a position that is exposed from the end of the lever plate only when the other end of the lever plate is pushed up by the drive unit. drilled,
A stopper is loosely fitted inside a guide tube fixed at a position aligned with this through hole on the outer surface of the handle, and is elastically applied by a second spring in a direction that projects inward of the handle. Pressure accumulation type automatic fire extinguishing system.
