Description

The present invention relates to a fire extinguishing sprinkler head.

The sprinkler head is installed in a state where it is mainly embedded in the ceiling of the room, and is connected to a pipe extending from the fire-fighting water supply source. The fire is suppressed and extinguished by spraying water sent from the source (see, for example, Patent Document 1).

The sprinkler head surface is legally required to display the operating temperature, sensitivity type, year of manufacture, and the like. In particular, the display of the operating temperature is identified by color and letter. For example, when the operating temperature is 72 ° C., it is colorless, 96 ° C. is white, 139 ° C. is blue, and so on.

JP 7-284545 A (page 2-4, FIG. 1)

However, since the temperature identification by the above color is regulated and customary, the use of the above-mentioned white, blue, etc. as the color of the sprinkler head itself may cause confusion in the operating temperature display. There was a problem that it could not be used practically.

In particular, the white color is close to the color of the wall and ceiling of the room, and a white sprinkler head has been desired for many years, but has not been realized.

In view of the above problems, an object of the present invention is to provide a sprinkler head that can be colored in the same manner as the interior color and can be temperature-identified.

In order to achieve the above object, the invention according to claim 1 is a sprinkler head identifying means comprising a storage device installed in the sprinkler head and a reader of the storage device.

The invention according to claim 2 is the sprinkler head identification means according to claim 1, wherein the reading device is capable of reading information stored in the storage device in a non-contact manner with the storage device.

The invention according to claim 3 is a sprinkler head characterized in that an element that outputs information by applying any one of light, a line, radio waves, and magnetic force is installed in the sprinkler head.

According to a fourth aspect of the present invention, there is provided a sprinkler head identification means capable of displaying information output from the element according to the third aspect by a reading device.

The invention according to claim 5 is a sprinkler head in which identification information is displayed on a surface by a material that is visible in a dark place. The sprinkler head covers the periphery of the sprinkler head and darkens the identification information. It is a means for identifying the head.

The invention according to claim 6 is a sprinkler head in which the storage device according to claim 1 is installed.

A seventh aspect of the present invention is a sprinkler head provided with a material that is visible in the dark according to the fifth aspect.

By installing a storage device that stores information such as operating temperature, type, year of manufacture, etc. on the sprinkler head, it is possible to read the information in the storage device with a non-contact type reading device. When obtaining the above, there is no possibility that the reader impacts the sprinkler head, affects the disassembling operation mechanism holding the valve body inside the sprinkler head, and causes no leakage from the valve body.

Further, according to a third aspect of the present invention, the element installed in the sprinkler head is normally inconspicuous, and information or display is output when a line such as light or infrared rays, radio wave, or magnetic force is applied. Can be identified.

According to a fourth aspect of the present invention, information is displayed in response to the output from the element of the third aspect. When the amount of information is large, the display can be performed by using a reader.

In claim 5, identification information is displayed on the surface of the sprinkler head by a material that can be seen in the dark, and when checking the temperature of the sprinkler head during inspection, the periphery of the sprinkler head is darkened. It becomes possible to read the identification information.

In carrying out the present invention, an IC tag, an IC chip, a barcode or the like is used as an example of the memory device described in claim 1 or the element described in claim 3, and a reading device and a display corresponding to the device are used. The sprinkler head can be identified by using the device.

As an example of the material according to claim 5, it is possible to use a fluorescent material, a phosphorescent material, a reflecting material, and the like.

Hereinafter, Example 1 will be described with reference to FIGS. FIG. 1 is an external view of a sprinkler head in which a storage device is installed. FIG. 2 is an explanatory diagram of a state in which information is read from the sprinkler head.

In the first embodiment, an IC tag 2 is attached to the surface of a sprinkler head 1 as shown in FIG. The IC tag 2 stores information such as the operating temperature of the sprinkler head 1, the type, the manufacturing year, and the manufacturing number.

At the time of inspection, when reading the information in the IC tag 2, the antenna 4 of the reader 3 is brought close to the sprinkler head 1 installed on the ceiling surface. Since the IC tag 2 and the reading device 3 can read the information in the IC tag 2 in a non-contact state, the antenna 4 does not contact the sprinkler head 1 and give an external force to the sprinkler head 1.

In the above case, the radio wave transmitted from the IC tag 2 may be received by the antenna 4 and displayed on the reading device 3, or the radio wave transmitted from the antenna 4 may be received by the IC tag 2, It is also possible to return the built-in information and display it on the reader 3.

Next, Example 2 will be described with reference to FIGS. FIG. 3 shows a sprinkler head in which an element that is visible by applying light, a line, radio waves, magnetic force, or the like to the surface is provided. FIG. 4 is a diagram of the sprinkler head of FIG. It is a display pattern.

In Example 2, the operating temperature is displayed on the surface of the sprinkler head of FIG. 3 by the element 5 that can be made visible by applying any one of light, line, radio wave, magnetic force and the like.

For example, if the sprinkler head H is applied with a radio wave of a certain frequency or a magnetic force of a predetermined level or higher, green is displayed when the operating temperature of the sprinkler head is 72 ° C, white is displayed when it is 96 ° C, and blue is displayed at 139 ° C It becomes.

Further, a figure may be visible as shown in FIG. 4A, or numbers and characters may be visible as shown in FIGS.

Furthermore, the sprinkler head can be identified by emitting light by giving a specific frequency. For example, an element installed in a sprinkler head having an operating temperature of 72 ° C. may emit light when receiving a frequency A, and an element having an operating temperature of 96 ° C. may emit light when receiving a frequency B. it can.

Next, Example 3 will be described with reference to FIG. FIG. 5 shows a state in which information applied to the surface of the sprinkler head is read.

In Example 3, the display shown in FIG. 4 is applied to the outer surface of the sprinkler head of Example 3 at the same position as the element 5 in FIG.

When identifying the operating temperature of the sprinkler head according to the third embodiment, as shown in FIG. 5, the tubular body 10 is brought into contact with the ceiling surface to cover the periphery of the sprinkler head H and the periphery of the sprinkler head H is darkened.

If the sprinkler head H is looked into from the lower side of the cylindrical body 10, the figure, characters, etc. displayed by the phosphorescent material will be visible, so that the operating temperature of the sprinkler head can be identified.

At that time, the cylindrical body 10 is preferably made of a material that does not transmit light or a black material. The color of the phosphorescent material is preferably the same as or similar to the color of the sprinkler head H, or transparent or translucent.
