SUMMARY OF THE INVENTION In a fire extinguisher for a vehicle according to the present invention, a. Spray nozzle 3 by fire pump 2
Fire extinguishing liquid 5 erupted from. Use an aqueous solution containing incombustible chloride compounds. In addition, the fire extinguishing liquid 5 ejected from the spray nozzle 3 becomes a fine mist so that it can be ejected uniformly over a wide range. Now. Due to a collision accident. When the fuel system is damaged and fuel leaks, causing a fire. in advance. Manual switch 4b installed on a car
By selecting and manually operating. Spray fire-extinguishing liquid 5 in a spray form where fire may occur. Configure so that fire can be prevented. still. Unfortunately. Ignite leaked fuel. If a car fire occurs. In particular. Sensor 4a (temperature sensor and flame sensor) even if the driver does nothing
By. Quickly detect fire. Fire pump 2 automatically
Is started, and the fire extinguishing liquid 5 can be sprinkled by the spray nozzle 3 in a spray state over all the combustion products over a wide range. Therefore. By covering the surface of the burning material with fine particles of the fire extinguishing liquid 5. Combustion is shut off from the air (cut off oxygen) and no more. You can no longer burn. Fire extinguished. in this case. It is configured in advance so that the fire pump 2 can be started by operating the manual switch 4b.

[0005]

The fire extinguishing liquid 5 used in the fire extinguishing system for an automobile according to the present invention uses an aqueous solution containing a nonflammable chloride compound.
Also. The fire extinguishing liquid 5 is sprayed from the spray nozzle 3 by the fire extinguishing pump 2 in the form of fine spray. for that reason. It quickly and reliably penetrates the small gaps between the combustibles and covers the surface of the combustibles. Break direct contact between combustion products and air (oxygen). Also. The fine particles of the fire extinguishing liquid are so sticky that they do not exfoliate easily and do not disappear. It is not affected by weather conditions such as surrounding conditions and wind and temperature changes in the event of a car fire accident. Fire can be extinguished reliably. Also. What about a fire caused by a car collision? This is because sparks due to breakage of the electrical wiring 7 often cause this. By using an electrically insulating chlorinated compound to be mixed into the fire extinguishing fluid 5. No fear of electric shock. The broken portion of the electric wiring 7 is completely covered with the spray-like fine particles of the fire extinguishing liquid 5. It is possible to suppress electric sparks thereafter and extinguish the burning material during combustion. From the above. Already. Not only can you extinguish the burning material that is burning by fire. There is a great advantage that a fire can be prevented from occurring. On the other hand. Since the fire extinguishing liquid 5 is used as fine particles in the form of spray, a small amount of the fire extinguishing liquid 5 can cover a wide spray area. Can extinguish fire effectively. Therefore. The fire extinguishing system for a vehicle according to the present invention can extinguish fire sufficiently even with a small amount of fire extinguishing liquid 5. The increase in fuel efficiency caused by mounting this fire extinguisher on an automobile is not a significant problem. Further. Fire extinguisher tank 1. Fire pump 2. The spray nozzles 3 are very small. There is no problem with the location in the car.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS There are the following six types of installation systems for a fire extinguisher of a vehicle according to the present invention. (1) The fire-extinguishing pump 2 is started by the manual switch 4b installed in the automobile, and the fire-extinguishing liquid 5 is sprayed to the peripheral portion of the engine by the spray nozzle 3 in a spray form. (2) The fire-extinguishing pump 2 is started by the sensors 4 a (temperature sensor and flame sensor) installed in the cab of the automobile, and the fire-extinguishing liquid 5 is sprayed into the cab by the spray nozzle 3. (3) The fire extinguishing pump 2 is started by the sensors 4a (temperature sensor and flame sensor) installed around the engine of the automobile, and the digestion liquid 5 is sprayed out of the spray nozzle 3 to the periphery of the engine. (4) The fire pump 2 is started by the sensor 4a (temperature sensor and flame sensor) installed around the fuel tank of the automobile, and the spray nozzle 3 causes the fire-extinguishing liquid 5 to be sprayed to the periphery of the fuel tank. (5) The fire pump 2 is started by the sensors 4a (temperature sensor and flame sensor) installed around the engine and the fuel tank of the automobile, and the digestion liquid 5 is sprayed by the spray nozzle 3 into the engine and the fuel tank, respectively. Spout to surrounding area. There are the above five types of fire extinguishing systems. FIG. 1 is an explanatory diagram relating to a system of a fire extinguisher of an automobile according to the present invention.
1 is a fire extinguishing liquid tank. 2 is a fire pump. Fire extinguisher 5
From the fire extinguishing liquid tank 1 to the spray nozzle 3 by the hose 6. Reference numeral 3 denotes a spray nozzle which mixes air into the fire extinguishing liquid 5 which has been pressure-fed by the fire extinguishing pump 2 to form a fine particle mist and adjust the injection amount to spray the same. 4a is a temperature sensor. The leaked fuel ignites. This is for detecting the temperature of the flame and automatically starting the fire pump 2 when a fire occurs. Also. In case of car fire. A time delay before starting the fire pump 2 is not allowed. If you are late, you may lose your life. The fire pump 2 is automatically started by the temperature sensor 4a promptly. The fire extinguishing liquid 5 is sprayed in a spray shape on a portion corresponding to a fire extinguishing range set by a spray nozzle 3 fixed in advance. 4b is a manual switch. This is a manual switch for starting the fire pump 2. A car accident revealed a fuel leak. At the time of not firing yet. For fire prevention. in advance. Spray the fire extinguishing liquid 5 in a spray form over the area that the fixed spray nozzle 3 can cover.
This is to prevent fire caused by ignition. 5 is a fire extinguishing liquid, which is nonflammable. and. It is an aqueous solution mixed with an electrically insulating chemical such as chloride. 6 is a hose. The fire extinguishing liquid tank 1 is connected to the fire extinguishing pump 2 and the spray nozzle 3 respectively. From the above. If the fuel device is damaged due to a collision accident and fuel flows out, the driver operates the manual switch 4a. Activate fire pump 2 and extinguish fire extinguishing liquid 5
Is sprayed from the spray nozzle 3 in the form of a spray and sprinkled on the combustion material, thereby preventing the leaked fuel from catching fire and causing a fire. on the other hand. If unfortunately a spilled fuel ignites and a fire occurs. Always. The fire-extinguishing pump 2 is automatically and immediately activated by the monitoring sensor 4a (temperature sensor and flame sensor), and the fire-extinguishing liquid 5 is sprayed from the spray nozzle 3. The fire is extinguished by injection into a preset combustion range.

[0007]

According to the fire extinguisher of the present invention, when a fuel leak occurs due to damage to a fuel device or a fuel tank caused by a collision accident, a rear-end collision accident, or a self-harm accident caused by rolling up of an iron plate, etc. To prevent car fires. Also. Unfortunately. If the leaked fuel ignites and a car fire occurs. Regardless of the driver's state, the fire pump 2 is automatically activated to extinguish the fire. Also. The amount of the fire extinguishing liquid 5 used in the fire extinguisher of the vehicle according to the present invention is sprayed and used. Sufficient fire extinguishing is possible even with a relatively small amount. Therefore. Even if the fire extinguisher for a vehicle according to the present invention is installed in a vehicle, it is relatively small. Because it is lightweight. There is almost no need to consider fuel efficiency deterioration due to installation location or weight increase. Also. The fire extinguisher according to the present invention comprises a fire extinguishing liquid. Fire extinguisher tank 1. Fire pump 2. Commonly used such as spray nozzle 3 and hose 6. Since it is made of inexpensive components with a long life, a highly reliable fire extinguishing system can be provided at low cost.
