The pressure is maintained at a pressure of gf / cm 2 . 5 is a conduit,
Numeral 6 denotes a heat-sensitive operating valve. The clapper 65 is pressed against the valve hole 66 by an arm 64 locked by a latch 63 via a stem 62 by a sprinkler head 61 provided on the outer wall of the valve, and is closed. I have. Reference numeral 7 denotes a different diameter elbow, the larger diameter side is connected to the secondary side of the valve 6, and the smaller diameter side is connected to the bubble discharge head 8 (see FIG. 2). 9 is a mounting base, which is a foam discharging head 8
It is attached to the wall surface 10 so that more foam flows along the wall surface 10 and flows into the pit 11 immediately below.

込み、泡が積層されて消火される。Next, the operation of the above device will be described. For example, when a fire occurs in the oil that has accumulated in the pit 11 or 13 of the oil tank oil dike, the heat breaks the glass valve of the sprinkler head 61 as a heat-sensitive element of the heat-sensitive operation valve, causing the latch to break.
63 comes off the arm 64 and the clapper 65 opens. As a result, the water film forming foam liquid 3 in the foam container 2 is replaced with the nitrogen gas 4.
Flows through the valve 6 and the elbow 7 of different diameter to the bubble discharge head 8, and the air is sucked and foamed. Then, the foam flows along the wall surface 10 to the oil surface of the pit 11 or 13, where the foam is stacked and extinguished.

小規模の段階で火災を消火することができる。In the above embodiment, the fire extinguisher is provided on the wall surface. However, the fire extinguishing device may be mounted on the ceiling surface and discharged to the wall surface. Further, in the above embodiment, the case where the fire extinguisher is installed in a complex or a parking lot is described. However, even if a tank lorry or the like falls down on a road and oil flows into an underground manhole or a common ditch and a fire occurs, the side wall of the manhole. If a pit is provided at an appropriate place or a fire extinguisher of the present invention is provided here,
Can extinguish fires on a small scale.
