Description of the Related Art Conventionally, there have been fire alarms for detecting and notifying the occurrence of fire and smoke detectors for detecting and notifying the occurrence of smoke as disaster prevention equipment in buildings. There was also a sprinkler-type fire extinguishing facility that automatically extinguishes water by discharging water when a fire alarm detects a fire.

るという問題点があった。However, in the conventional sprinkler type fire extinguishing equipment, water is discharged in a shower-like manner in the entire room regardless of where the fire source is.
Fire extinguishing efficiency is poor. Further, since water is discharged to a place where it is not necessary to extinguish a fire, not only is the water wasted, but there is also a drawback that an extra place is wetted and damaged. Further, since the water discharge continues until the water discharge is stopped manually, there is a problem that if the stop is delayed, the room will be flooded and the damage due to the water discharge will increase.

Another object of the present invention is to provide an automatic flame detection and extinguishing system capable of efficiently and reliably extinguishing a fire in a short time with the amount of water discharged, and minimizing damage caused by water discharge.

When the flame 2 of the fire source is detected by, the detection signal is sent to the controller 6, and the controller 6 automatically turns on the power of the infrared sensor 3. As a result, the infrared sensor 3 shakes its head in all directions of 360 degrees to detect the infrared rays contained in the flame 2, and stops at the position where the flame 2 is detected. At this time, the water discharge nozzle 4 attached to the infrared sensor 3 also faces the flame 2. Furthermore, when the infrared sensor 3 detects the flame 2,
When the detection signal is continuously output from the flame detector 1, the electromagnetic valve 7 attached to the water supply pipe 10 opens, and at the same time, the plunger pump 9 operates to supply the water from the water storage tank 8 to the water supply pipe 10. Water is discharged toward the flame 2 from the water discharge nozzle 4 that faces the flame 2. In this case, claim 2
In the invention, since the water is discharged only when the detection signals are output from both the flame sensor 1 and the infrared sensor 3,
When only one of the flame detector 1 or the infrared detector 3 operates, for example, when the flame detector 1 or the infrared detector 3 malfunctions, or when a lighter ignites for smoking, water is sprayed. There is nothing to do. According to the invention of claim 3,
When the flame 2 is extinguished and one or both of the flame sensor 1 and the infrared sensor 3 no longer sense the flame 2, the electromagnetic valve 7 is automatically closed via the controller 6 and the water from the water discharge nozzle 4 is discharged. Water discharge is automatically stopped. In the invention of claim 4, two or more water supply pipes 10 for supplying water to the water discharge nozzle 4 are provided, and since water is discharged only from the water supply pipe 10 that senses the flame 2, it is possible that an extra portion gets wet with water. No water is wasted.

Reference numeral 1 in FIG. 1 is a flame detector, which is installed on a ceiling or a wall in a room to detect the occurrence of a disaster and outputs the detection signal to the controller 6. It is desirable that the flame detector 1 is a smoke detector combined type equipped with a smoke detector, since a flame is rarely generated immediately at the beginning of a fire and only smoke is often generated. . Reference numeral 3 in FIG. 1 is an infrared sensor, which is similar to the existing infrared sensor,
When it detects the infrared rays contained in the flame, it outputs a detection signal, but it does not just detect the infrared rays but also automatically swings in any direction by 360 ° by a swinging mechanism (not shown). It is designed to detect and detect infrared rays. An existing rotation mechanism can be used as the swing mechanism. Reference numeral 4 in FIG. 1 denotes a water discharge nozzle, which is attached to the infrared sensor 3 and is rotated together with the infrared sensor 3 in any direction by 360 degrees so that the infrared sensor 3 can detect the flame 2. Upon detection, the water discharge port of the water discharge nozzle 4 automatically faces the flame 2.

When receiving the detection signal from the flame detector 1, the infrared detector 3 is turned on and the infrared detector 3 is rotated to search the flame 2. When the infrared sensor 3 detects the heat source and the detection signal is continuously output from the flame sensor 1, the electromagnetic valve 7 is opened, the plunger pump 9 is operated, and the water in the water storage tank 8 is activated. Is pressurized to supply water to the water supply pipe 10, and the water is discharged from the water discharge nozzle 4. Also,
When the detection signal from one or both of the flame detector 1 and the infrared detector 3 is stopped, this controller 6 closes the electromagnetic valve 7 and stops the plunger pump 9 to stop the water supply. .

In these cases, when any one of the flame detectors 1 and infrared detectors 3 of the water discharge system detects the flame 2, the electromagnetic valves 7 of all the water discharge systems do not open all at once, but the flame detectors 1 and It is preferable to open only the electromagnetic valve 7 of the water discharge system in which both of the infrared ray detectors 3 are outputting detection signals. This is to minimize the damage caused by water wetting in the room caused by discharging water to a place other than the fire source.
