Abstract

PURPOSE:To enable prevention of a fire in a vehicle resulting from a conductor car fallen down sidelong, by a method wherein unusual tilting angle of the car body of the conductor car is detected, and water is injected into a pot of an oil stove automatically so that a fire is extinguished promptly. CONSTITUTION:A tilting angle of a car body under unusual state of cars provided with a pot type oil stove 1 is detected by a detector 6, and a solenoid valve 7 is actuated by a detecting signal of the detector 6. Air of fixed pressure is injected into a sealed water tank 9 which contains water of fixed quantity through air ducts 15-17, and a water duct 13 for injection of the water within the water tank 9 into a pot 2 of the coil stove 1 is rovided as well. Namely, the water within the water tank 9 is made to inject into the pot 2 of the oil stove 1 through the water duct 13 by the action of the solenoid valve 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency fire extinguishing method and device for a pot-type kerosene stove for a vehicle.

The last car of a freight train is a caboose or a car equipped with a conductor's room.In winter, the caboose is usually equipped with a pot-type kerosene stove to keep the conductor warm while he is working. There is.

However, while the conductor was working, that is, while the kerosene stove was burning, an abnormality such as a train accident occurred! If an IK failure occurs, such as a vehicle overturning, disasters such as a vehicle fire may spread, leading to a serious accident.

The present invention has been made in order to solve the above-mentioned problems regarding kerosene stoves installed in the caboose of freight trains.

The present invention is carried out according to the embodiment shown in FIGS. 1-3! 5!
I will clarify.

In Figure 11t1, numeral 1 indicates a known pot-type kerosene stove installed in the caboose of a freight train. A predetermined amount of oil 22 is continuously supplied into the pot 2 via a fuel (oil) tank (not shown), an oil amount adjustment valve, and an oil passage 3. A plurality of through holes 21 are formed on the upper outer circumference of the pot 2, and when the oil 22 in the pot 2 is ignited,
The vaporized petroleum 22 mixes with the air entering the pot 2 through the through hole 21t and continues normal combustion. In addition, 4
is a chimney whose upper end protrudes into the roof of the caboose and opens to the outside air. 5 is a peephole for viewing the combustion status inside the pot 2, and 10 is the top lid of the kerosene stove. Reference numeral 6 denotes a detector for detecting an abnormal body inclination angle that does not occur when the caboose is in normal running conditions, and as shown in Fig. 2(a), it is composed of, for example, two mercury switches 61 and 61. . The mercury switches 61, 61' are mounted at right angles to the longitudinal direction of the vehicle and symmetrically with respect to the centerline cK in the loading plane at an angle of inclination α. Here, the angle α is the U contact point 611 at the inclination of body #1 due to rolling of the caboose in normal running condition.
11 When the toro 12'df water s, 62 or a62' is not closed and an abnormal car body lean angle is taken that may lead to or may lead to the conductor overturning, the contacts 611 and 612
Alternatively, 611° and 612° are set to be closed with mercury 62 or 62.

Reference numeral 15 is an air passage for pressurized air of, for example, about 1 to /d, and is a "normally open" cock 11. It is connected to a closed water tank 9 containing a predetermined amount of water via a solenoid valve 7t. The air passage 17 is connected to an air passage 16 into which a parallel K "normally closed" cock 12 is inserted. E is power supply, 8
Fi contacts 611.612.611', 61 of the mercury switch 61.61° through the terminals of terminal block 8 on its terminal block
2° and solenoid valve 7 are connected to power source E. Reference numeral 13 denotes a water injection passage whose one end is attached to the lower part of the water tank 9 and the other end 14 passes through the main body of the kerosene stove I, so that it is oriented in the direction of the pot 2. Note that 18 is a drain plug for the water tank 9, and 19 is a mounting plate for the device according to the present invention.

In such a configuration, while the caboose continues to run normally, the inclination angle of the car body due to rolling remains within a predetermined range, and the contact 61 of the mercury switch 61 or 61'
1.612 or 611', 612" is not closed via mercury 62 or 62, the circuit of power supply E, detector 6 and solenoid valve 7 is not configured, and solenoid valve 7 remains inoperable. The air passage 15 is kept closed by the electromagnetic valve 7, so that no pressurized air is radiated into the water tank 9, and the oil stalk 1 continues to burn normally.

If the caboose takes an abnormal tilt angle due to a train accident, etc., the contacts 611, 61 of the mercury switch 61 or 61"
2 or 611,612 is 62 or 62t of mercury
-, a circuit of the power supply E, the detector 6 and the solenoid valve 7 is configured, the solenoid valve 7 is activated 9, the air passage 15 is opened, and the pressurized air is supplied to the air passage 15 at all times. Open” cook 11. The water flows into the water tank 9 through the electromagnetic valve 7, and the pressure air injects the water in the water tank 9 into the pot 2 through the water injection passage 13 to extinguish the kerosene stove.
This will prevent the spread of the disaster.In addition, if necessary, manually open the cock 12 that is set to "normally close" and open it to allow pressurized air to flow into the water tank 9 and spray water to extinguish the fire. Also, the detector 6 can be used as shown in Fig. 2(a).
In addition to the K shown, one V as shown in Figure 2(b)
A 6° shaped mercury switch may also be used. The V-shaped mercury switch 6'' is provided in a plane that is straight and perpendicular to the longitudinal direction of the caboose, similar to the one shown in FIG.
The sides are each symmetrically inclined at an angle α with respect to the center l1IC.

According to the present invention, when the caboose is normally running, the kerosene stove can be burned normally to effectively heat the caboose during work, and once an abnormal situation such as a train accident occurs, The system is configured to detect an abnormal tilt angle of the car body and automatically inject water into the pot of the kerosene stove to extinguish the fire immediately. can be prevented from occurring, and the spread of this type of disaster can be effectively prevented.

The power source E used in the present invention may be either direct current or alternating current, but the 24 V direct current storage battery conventionally installed in caboose can be used as is, and the compressed air can be compressed air from the existing air brake pipe. You can reduce the pressure with a pressure regulator or a pressure reducing valve, store it in an air reservoir, and use the air reservoir as a compressed air supply source, or use a liw/c/ Since existing mechanisms such as L compressed air can be used, an extremely economical fire extinguishing system can be realized.

FIG. 3 shows an embodiment of the ship 2 of the present invention, and the same symbols as those shown in FIG. 1 and the JGZ diagram indicate the same components.

Comparing this embodiment with the embodiment of Tate 1, in the 10th rear embodiment, the electromagnetic valve 7 is activated by the detection by the detector 6, and compressed air is applied to the water tank 9 for the first time. 21C water is injected, but in this embodiment, compressed air is always applied to the water in the water tank 9, and the water electromagnetic valve 7 is operated by detecting an abnormal single tilt angle of the detector 6. , or the same as in the first embodiment except that the water in the water tank 9 is injected into the pot 2 by manually opening the cock 12 which is normally closed. ,0 which can achieve the purpose of the present invention
