Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an automatic fire extinguishing system for vehicles, especially in the event of a fire in the engine compartment. Automatically directs engine cooling water to the engine when an abnormality such as a disaster or smoke occurs. This invention relates to an extremely safe automatic fire extinguishing system for vehicles that extinguishes fire by emitting water.

[Conventional technology]

Conventional methods of extinguishing fires in vehicles include installing a fire extinguisher in the driver's seat and using the extinguisher in the event of a fire. The driver and others were extinguishing the fire, but when the fire ignited inside the engine compartment due to the collision, If the driver is injured, or even if he is not injured, he may be upset and suddenly It was often difficult to take action, making it difficult to extinguish fires in the early stages when they are effective. . Also, opening the engine lid to extinguish the fire is not a good idea if there is a flame when the engine lid is opened. In practice, it is extremely difficult to extinguish a fire inside the engine room because there is a risk of the fire blowing out. Met.

0003 In order to solve the above drawbacks, Utility Model Application No. 57-63761 or No. 54 is equipped with a fire extinguisher in the engine room, and the fire extinguisher can be operated from the driver's seat. However, in this conventional example, the driver does not have to operate the fire extinguishing system. If the driver is injured, or even if the driver is not injured, you may be concerned. In some cases, firefighters were unable to actually extinguish the fire if they were upset. Also large In vehicles where the engine is located at the rear, away from the driver's seat, such as a model bus, etc. However, there were problems in that it was difficult to notice the ignition, and the initial extinguishing process was likely to be delayed. Fire extinguishing again Depending on the type of extinguishing agent, unpleasant gas may be generated or the fire may be extinguished. There were drawbacks such as difficulty in cleaning the engine compartment afterwards.

[Problem to be solved by the invention]

The present invention was made in order to eliminate the drawbacks of the above-mentioned prior art. The purpose is to install a temperature and smoke sensor in the engine compartment of a vehicle and measure the temperature. ignition by automatically performing extinguishing operations based on abnormal signals from the smoke sensor. This means that the fire can be extinguished immediately after the fire is extinguished, and this makes the initial fire extinguishment effective. Even if the driver is injured or upset, there is no need to provide any support. The goal is to extinguish the fire without any problems and prevent danger to the driver and passengers. Also Other purposes use special equipment by extinguishing fires using engine cooling water. The purpose is to extinguish the fire without causing any damage to the engine, and also to avoid the usual use of engine cooling water. The fire extinguishing system can be activated at any time in an emergency by simply checking that the fire extinguisher is The goal is to be able to do this. Furthermore, the above configuration reduces the possibility of unpleasant gas generation. To provide a fire extinguishing system for a vehicle that is free from leakage and has a very simple structure.

[Means to solve the problem]

In short, the present invention detects the temperature or presence of smoke in the engine compartment of a vehicle and makes an error. Temperature and smoke sensors that constantly send signals and engine cooling water are supplied to detect the abnormality. At normal times, the cooling water is directed to the engine based on the temperature and the signal from the smoke sensor. It is characterized by being equipped with a solenoid valve that ejects water.

[0006]

【Example】

The present invention will be explained below based on embodiments shown in the drawings. In Figure 1, An automatic fire extinguishing system 1 for a vehicle includes a temperature sensor 2, a smoke sensor 2, and a solenoid valve 3. The temperature and smoke sensor 2 is for detecting the temperature or presence of smoke in the engine room 4. This is a known cell installed above the engine 5 in the engine room 4. If the temperature in the engine room 4 suddenly rises or smoke is generated, This is detected and an abnormal signal is sent to the solenoid valve 3 or the buzzer 6.

[0007] The solenoid valve 3 is for spouting cooling water for the engine 5 toward the engine 5. The water supply port 3a is connected to the water manifold 9 of the engine 5 through a pipe 8. The drain port 3b is connected to the engine room 4 with the drain port 3b facing the engine 5. Fixed. Then, normally a valve (not shown) is closed by the action of a spring 10. Therefore, cooling water does not spout out from the drain port 3b. Also, the solenoid valve 3 A solenoid (not shown) is connected to a temperature and smoke sensor via a battery 12 by an electrical cord 11. It is electrically connected to sensor 2.

[0008] The present invention is constructed as described above, and its operation will be explained below. figure 1, the solenoid valve 3 is connected to the pipe 8 from the water manifold 9 of the engine 5. Cooling water is supplied to engine 5, but normally the valve is closed, so cooling is not possible. Water does not gush out from the drain port 3b.

[0009] Here, in the unlikely event that the engine 5 overheats or a collision occurs, there is a When a fire occurs, the temperature and smoke sensor 2 detects this and sends an abnormal signal to the solenoid valve 3 or buzzer 6. Send to. In response to the abnormality signal, the buzzer 6 is activated to emit an alarm sound and notify the abnormality. At the same time, the solenoid (not shown) of the solenoid valve 3 is energized, and the spring 10 is activated. Activate the valve against the action of , and open the drain port 3b. And water maniho Cooling water for engine 5, which was supplied from field 9 through pipe 8, is transferred to engine 5. The fuel is vigorously sprayed towards the target to extinguish the fire and cool the inside of the engine room 4. The fire extinguishing operation Since this work is carried out at the very early stage of a fire, it is possible to efficiently extinguish the fire with a small amount of cooling water. and is completely automatic, so even in the unlikely event of an accident the driver is not injured. It is possible to completely extinguish a fire even if you are unable to move.

【Effect of the invention】

As mentioned above, this invention installs temperature and smoke sensors in the engine compartment of the vehicle. The system automatically extinguishes fires based on temperature and abnormal signals from smoke sensors. This has the effect of extinguishing the fire immediately after it ignites, and as a result, the initial extinguishing is effective. Even if the driver is injured or upset, there is no need to worry. The effect of being able to extinguish the fire without any problems and prevent danger to the driver and passengers. There is. Also, special equipment must be used to extinguish the fire using engine cooling water. It has the effect of extinguishing a fire without any problems, and it also helps to check the presence of engine cooling water, which is normally done. The fire extinguishing system can be activated at any time in an emergency with simple maintenance work. It has excellent effects. Furthermore, with the above configuration, there is no risk of unpleasant gas generation. It is also extremely advantageous to provide a vehicle fire extinguishing system with a very simple structure. Ru.
