Abstract

PROBLEM TO BE SOLVED: To effectively prevent a vehicle fire after an accident by enclosing an airtight vessel in a part of a car body by compressively filling incombustible gas or a fire extinguisher in the airtight vessel, and discharging the inside incombustible gas or the fire extinguisher by receiving pressure not less than prescribed pressure to the airtight vessel. SOLUTION: An airtight vessel 1 filled with incombustible gas or a fire extinguisher is housed in the back part of a U-shaped bumper 6 to be fixed to the bumper 6 by a proper fixing metal fitting 10. Exhaust pipes 11, 11 are extended in the airtight vessel 1 enclosed in the bumper 6 so that these exhaust pipes 11 are introduced into an engine room. The burst part 12 weaker than the other is formed by a press in a connecting place of the bumper 6 and the exhaust pipes 11 as one example of a gas injection means 3. A vehicle fire can be reliably prevented by injecting the incombustible gas or the fire extinguisher into the engine room through the exhaust pipes 1 by breaking the burst part 12 being the gas injection means 3 since internal pressure increases after the airtight vessel 1 is deformed when pressure not less than prescribed pressure is applied to the airtight vessel 1 by impact to the bumper 6 at collision time of an automobile.

FIG. 1A is a schematic perspective view, and FIGS. 1B and 1C are schematic cross-sectional views. In the present embodiment, the non-combustible gas is compressed, filled in the airtight container 1 and incorporated in the bumper 6 constituting a part of the body of the automobile. The nonflammable gas includes carbon dioxide gas, nitrogen gas, and the like, and any nonflammable gas may be used as long as it has nonflammability and is less harmful to the human body.

A fire extinguisher may be used in place of the nonflammable gas. As a fire extinguisher, it is used for acid-alkali fire extinguishers and emits acid-alkali (including a mixture of an inorganic salt or an aqueous solution of a salt thereof and an alkali salt, or a mixture containing or adding a wetting agent) under pressure. Fire extinguishing. Alternatively, a fire extinguisher that is used for a fire extinguisher and that extinguishes the fire by irradiating a strengthening liquid (including an aqueous solution of an alkali metal salt, a wetting agent, or the like added or added thereto) by pressure.
Alternatively, a fire extinguisher that emits foam (a chemical foam that has a fire-extinguishing effect by a chemical reaction) under pressure to extinguish a fire. Or halides (halon 1011 and halon 2402, which are evaporating liquids, and halon 1211 and halon 1 which compress and liquefy gas at normal temperature and normal pressure).
There is 301. Fire extinguishing by radiating pressure (including those mixed or added with an infiltrant). Or, it is used for carbon dioxide digesters and extinguishes fire by emitting liquefied carbon dioxide by pressure. Or, used for powder type digestive organs, mixed with or added to powder (sodium or potassium bicarbonate or other salts or phosphates or other flame-resistant salts, moisture-proofed salts, infiltrant, etc.) Fire extinguishing fire) by radiating water by pressure.

The above-mentioned digestive agent is stored in a pressure accumulating digester (a digestive device that emits a fire extinguisher by the pressure of compressed air or nitrogen gas in the digestive device, or the pressure of the digestive agent filled in the digestive device). The airtight container 1 is filled in the same manner as in the case of (1).
By the way, the filling pressure of the non-combustible gas or the extinguishing agent filled in the airtight container 1 is 17 kgf as seen in general digestive organs.
/ Cm ^{2 to} 19 kgf / cm ² . In addition, airtight container 1
