DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fire extinguishing system in which at least four or more powder fire extinguishing systems are installed in indoor / outdoor parking lots, factories, warehouses, and the like. The aim is to reduce the emissions.

[0002]

2. Description of the Related Art As a conventional fire extinguishing system generally installed in indoor / outdoor parking lots, etc., as shown in FIGS. 3 and 4, a stationary storage having a door 3 which can be opened and closed by a knob 2 is shown. In a box 1, a main container 4 filled with a powder fire extinguisher,
A pressurized gas container 7, a discharge hose 11, and a cleaning gas container 16 are each provided.

That is, the main body container 4 is filled with a powder fire extinguishing agent, and mounting portions 5 and 14 are provided on side surfaces of the main body container 4. A pressurized gas container 7 is connected to the inside of the container 4, and a cleaning gas container 16 is connected to the other mounting portion 14 by a connection nut 15, and is also connected to the inside of the main container 4. .

[0004] Further, a long discharge hose 11 is connected to the main body container 4 via a discharge valve 10 through a connection portion 9, and is wound up and down in the storage box 1.
Further, a safety valve 18 for preventing damage of the discharge hose 11 due to discharge of high-pressure gas such as carbon dioxide from the pressurized gas container 7 is provided at an upper portion of the main body container 4. Pipe 2 between the outlet
0 is interposed.

In such a configuration, when a fire occurs, the discharge hose 11 is pulled out, the valve 8 and the discharge valve 10 of the pressurized gas container 7 are opened, and
Gas such as carbon dioxide gas is pumped into the inside. As a result, the inside of the main body container 4 is pressurized, and the powder fire extinguishing agent is sent out from the connection portion 9 to the discharge hose 11, and the nozzle opening / closing valve 13 at the tip is opened, and the fire extinguishing agent is emitted from the nozzle 12 toward the fire extinguishing target area.

On the other hand, after the fire extinguishing activity is completed, when the nozzle opening / closing valve 13 is closed in a state where the fire extinguishing agent is not fully radiated and the discharge hose 11 is clogged with the powder fire extinguishing agent, the pressurized gas in the main body container 4 is Passes through the fire extinguishing agent in the discharge hose 11 and is gradually released from the gap of the nozzle opening / closing valve 13, and the powder fire extinguishing agent remaining in the discharge hose 11 solidifies over time, and when a fire occurs thereafter, It is necessary to clean the inside of the discharge hose 11 from a place where the discharge hose 11 can no longer be used.

In the cleaning operation, the valve 8 and the discharge valve 10 of the pressurizing gas container 7 are closed, the cleaning valve 19 and the nozzle opening / closing valve 13 are opened, and in this state, the valve 17 of the cleaning gas container 16 is opened to perform cleaning. The carbon dioxide gas in the gas container 16 is supplied from the attachment portion 14 into the main body container 4.

Further, the cleaning gas supplied from the cleaning gas container 16 passes through the cleaning valve 19 mounted on the upper portion of the main container 4 and is supplied through the pipe 20 into the discharge hose 11.
All of the powder fire extinguishing agent remaining in the discharge hose 11 is discharged to the outside from the nozzle 12 at the tip to complete the cleaning.

[0009]

However, the above-mentioned general-purpose stationary fire extinguisher has a relatively complicated structure, a large weight, a high cost, and an inspection item at the time of maintenance every several years. To increase. Also indoors
It is necessary to install a large number of stationary fire extinguishers to provide disaster prevention equipment in all relatively large areas, such as outside parking lots, factories, warehouses, etc. It is only time, and even if a fire occurs, it is unlikely that all of the stationary fire extinguishers will be operated. Even if the hose is extended and used for fire fighting, it usually surrounds the ignition point.
Up to about a table. Further, the cleaning of the discharge hose is wasteful because nothing is required for the fire fighting operation itself accompanying the fire.

[0010]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention does not require each of a large number of stationary fire extinguishing devices to be provided with the above-mentioned cleaning gas container, and is used for fire extinguishing activities. Even if a maximum of four fire extinguishers are used, all of the four stationary fire extinguishers used must have enough cleaning gas containers to carry out cleaning work inside the discharge hose and put them in a separate storage box. It was devised based on the finding that storing and installing this in the fire extinguishing system is more meaningful from the viewpoint of simplifying the structure and reducing costs.

That is, the present invention provides a main body container filled with a powder fire extinguishing agent, a discharge hose connected to the main body container and having a nozzle at a tip thereof, and a powder fire extinguishing agent supplied by supplying a pressurized gas into the main body container. Fire extinguisher equipped with four or more stationary powder fire extinguishers equipped with a pressurized gas container for discharging gas from the tip nozzle via the discharge hose, does not have a cleaning gas container in each stationary powder fire extinguisher In addition, the present invention relates to a fire extinguisher in which four cleaning gas containers connectable to the main container of each stationary powder fire extinguisher are housed in a storage box separately provided in the area of the fire extinguishing equipment.

In the above configuration, after the fire extinguishing activity accompanying the occurrence of the fire is completed, when cleaning the stationary powder fire extinguisher used, the required number of cleaning gas containers are taken out of the storage box provided with four cleaning gas containers. By connecting these to the pressurized gas container of the stationary powder fire extinguisher to be cleaned, they are connected to the inside of the main body container, and the cleaning gas is sent from the inside of the main body container to the discharge hose via the cleaning valve and the pipe,
The powder extinguishing agent remaining in the discharge hose is ejected from the tip nozzle and removed.

In FIG. 2, reference numeral 33 denotes a cleaning gas container storage box having a cantilevered opening / closing door 37 on the front side, which is attached and attached to the side surface of the storage box 21. The cleaning gas containers 35 are stored, and each cleaning gas container 35 is fixed by a fixture 34. In the drawing, reference numeral 36 denotes a connection screw provided at an upper portion of each cleaning gas container.

As described above, according to the present invention, as shown in FIG. 1, a fire extinguishing system comprising four or more stationary powder fire extinguishing apparatuses without a cleaning gas container, and a fire extinguishing system installed in the area of the fire extinguishing system. However, as shown in FIG. 2, it is characterized by comprising a storage box containing four cleaning gas containers.

In this case, out of the four or more stationary powder fire extinguishers, at least four stationary powder fire extinguishers equipped with a storage box accommodating a pressurized gas container for cleaning are installed. In the stationary powder fire extinguisher group, if it is located as close to the center as possible, carry the cleaning pressurized gas container to any of the stationary powder fire extinguishers installed. This is more preferable because the moving distance is relatively short, and the cleaning operation inside the discharge hose and other maintenance are easy.

In the above embodiment, the case where the storage box 33 of the cleaning gas container is attached to the outer side surface of the storage box 21 in the specific stationary powder fire extinguishing apparatus has been described. The configuration is not limited to such a configuration, and the installation location of the storage box 21 storing the four cleaning gas containers is as follows.
In the area of the fire extinguishing equipment, it may be installed at any place, such as laying it alone on the floor or mounting it on a wall surface.

In such a configuration, when a fire occurs in the installation area of at least four or more stationary powder fire extinguisher groups, the discharge hose 28 is pulled out from one or more stationary powder fire extinguisher corresponding to the fire occurrence location. Then, the valve 25 and the discharge valve 27 of the pressurized gas container 24 are opened, and a gas such as carbon dioxide gas is pressure-fed from the mounting portion 23 into the main body container 22. As a result, the inside of the main body container 22 is pressurized, and the powder fire extinguishing agent is sent out from the connection portion 26 to the discharge hose 28, and the nozzle opening / closing valve 30 at the end is opened to open the nozzle 29.
The fire extinguishing agent is radiated more toward the fire extinguishing area.

After the fire extinguishing operation is completed, when the nozzle opening / closing valve 30 is closed in a state where the fire extinguishing agent is not completely radiated and the discharge hose 28 is clogged with the powder fire extinguishing agent, the pressure gas in the main body container 22 is discharged. After passing through the fire extinguishing agent in the hose 28, it is gradually released from the gap of the nozzle opening / closing valve 30, and the powder fire extinguishing agent remaining in the discharging hose 28 solidifies over time. The cleaning of the discharge hose 28 is performed after use since it is likely to become unusable.

That is, when performing the cleaning operation, first, from inside the storage box 33 of the cleaning gas container,
The fixing metal fittings 34 are removed and the required number of cleaning gas containers 35 are taken out, taken into the storage box 21 of the stationary powder fire extinguishing apparatus requiring cleaning, and the valve 25 of the pressurized gas container 24 in the storage box 21 is removed. And the discharge valve 27 is closed, and at the mounting portion 23 of the pressurizing gas container 24, the mounting screw is loosened to remove the pressurizing gas container 24 from the main body container 22, and the aforementioned cleaning gas is replaced with the pressurizing gas container 24. Container 35
Is connected to the main body container 22 by attaching it with the connection screw 36.

Subsequently, the cleaning valve 31 is opened. In this state, the valve of the cleaning gas container 35 is opened, and the carbon dioxide gas in the cleaning gas container 35 is removed.
It is supplied from the mounting part 23 into the main body container 22. Further, the cleaning gas supplied from the cleaning gas container 35 is supplied from the inside of the main body container 22 into the discharge hose 28 via the cleaning valve 31 and the pipe 32 attached thereto, and remains in the discharge hose 28. All the powder extinguishing agent is discharged outside the nozzle 29 at the tip to complete the cleaning.
