Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of disposable simple manual fire extinguishing gas injection equipment.

[0002]

2. Description of the Related Art As a conventional simple manual fire extinguishing gas injection device, there is Japanese Patent Application No. 6-133811. This fire extinguisher gas injection device hits the head side of the cylinder with a hand, and by hitting it, the firing pin breaks the sealing plate of the cylinder head, injects the extinguishing gas filling the cylinder, and the injected gas is the cylinder. It was a mechanism to extinguish the original fire by injecting from the injection hole of the cover formed on the bottom side of the.

Therefore, the sealing plate of the cylinder is smashed and fire extinguishing gas is jetted, and the jetted fire extinguishing gas reaches the bottom of the pipe body through the void in the pipe, and the fire extinguishing gas that has arrived is formed at the bottom of the cover. The pressure of the high-pressure filled fire-extinguishing gas was reduced and the fire-extinguishing ability was proportionally reduced by the time it was injected from the injection holes.

Further, in the conventional simple manual fire extinguishing gas injection device, the structure of the pipe body and the cover covering the cylinder is
In order to sufficiently withstand the pressure of the high-pressure fire extinguishing gas and to protect the fingers that are gripping it from being cooled by the high-pressure gas, a double system is adopted, which has caused a rise in manufacturing costs.

[0005]

However, according to the present invention,
First, the bottom side of the cylinder protruding from the lower cover is struck like a mallet, and can be struck against the wall or floor while holding the cover, or by tapping the bottom of the cylinder with your hand. The plate was smashed and immediately the high-pressure fire-extinguishing gas was injected to the outside in the direction of injection from the cylinder and in the straight-ahead direction. Secondly, the fire extinguisher gas injection device of the present invention, even if the cooling heat of about −45 ° C. generated with the injection of the high pressure fire extinguishing gas is generated, the gas is discharged from the gap between the cylinder and the lower cover. Even if it escapes toward the bottom and grips the lower cover, burns do not occur. Thirdly, the component members other than the cylinder can be made of synthetic resin so that the product unit price can be reduced. Is the one

It is an injection device.

[0008]

The operation of the present invention will be described below.

The disposable manual fire-extinguishing gas injection device of the present invention includes a computer room, an engine room, a ship, a driving room of a vehicle, a power distribution room, a power source room, a boiler room, a container for a ignited material, an automatic power generation room, a heating equipment room, and an important room. Storage of goods, archives,
It will be equipped with disaster prevention equipment in case of a fire such as an art store, pyrotechnic appliances, and cabinets for gas products.

In case of ignition or ignition in the room, the interior, or the cabinet, the gas injection device is operated to prevent the origin or ignition of the gas.

When a fire is generated in the room, the lower cover of the fire extinguishing gas injection device of the present invention is firmly held with one hand, and the safety plate is pulled out with one hand.

After pulling out the safety plate as described above, aim the front part of the nozzle toward the fire occurrence point and tap the bottom part of the cylinder with the palm of the hand, or hit the bottom part of the cylinder with a hammer on the pillar, floor, etc. Then, the whole cylinder and the cylinder support portion supporting the cylinder move forward. When the cylinder advances as described above, the firing pin breaks the sealing plate, and the high-pressure fire-extinguishing gas is jetted by the breaking of the sealing plate, and is jetted from the jet hole.

When the bottom portion of the cylinder is hit as described above, only the constituent members of the cylinder and the cylinder support portion move, and the other constituent members remain stationary.

Further, as described above, when the extinguishing gas is injected from the cylinder, even if the cooling heat of about -45 ° C. is generated outside the cylinder, it is downward from the gap formed between the cylinder and the lower cover. It is discharged from the lower opening of the cover.
Therefore, the fingers holding the lower cover do not get burned.

The fire-extinguishing gas injection device of the present invention depends on the amount of liquid gas filled in the cylinder, but if the distance from the fire occurrence point is 2 m or less, even in a large room, the point of direct fire It is possible to extinguish the fire by injecting it into.

The injection device of the present invention is intended for initial fire extinguishing, has a simple structure, and can be operated by any person.

The injected gas is strongly injected from the injection hole to rapidly cool the original flame of the combustion product to extinguish the cooling.

Further, the liquid gas injected from the cylinder is vaporized to become vaporized gas, and the vaporized gas becomes an explosive expansion amount, and the inside of the room or the inside of the chamber is made oxygen deficient. The oxygen deficiency is 21
The calculation is performed in a room or a storage room where the amount of oxygen can be reduced to 15% or less, and the number of lines is set according to the Leubey calculation.

Further, in the liquid gas manual injection device of the present invention, the time from the break of the sealing plate to the injection of the gas is completely different from the mechanism of the conventional fire extinguisher, and the speed and diffusion are extremely strong. In addition, it has the function of injecting gas without reducing the pressure to the end and performing cooling and extinguishing activities, and at the same time, creating an oxygen deficiency state by explosive mass production of vaporized gas to complete the extinguishing activity.

Further, there is no possibility that the vaporized gas accompanying the injection of the liquid gas according to the present invention causes various indoor equipment, important items, documents, etc. to be spilled and contaminated.
