Abstract

(57) [Summary] [Purpose] To provide a signal extraction structure for an alarm that does not require routing of signal lines and has an excellent indoor appearance. [Structure] A detection signal emitted from an alarm 10 is transmitted to a cutoff valve of a gas meter 4 via an existing electric light line 22 installed indoors, and the cutoff valve is activated.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a gas leak alarm installed indoors (hereinafter simply referred to as an alarm). The detected gas leak detection signal is transmitted to the gas meter's shutoff valve, and the shutoff valve is activated. This invention relates to a signal extraction structure for an activated alarm.

0002

[Conventional technology]

An alarm device that detects indoor gas leaks and activates the shutoff valve built into the gas meter. , widely used to prevent accidents. Figure 3 shows the conventional alarm signal extraction structure. An example is shown. In the figure, a gas cylinder 1 installed outdoors is connected via a pressure regulator 2. It is connected to a gas meter 4 by a pipe 3. Gas meter 4 was buried underground It is connected to indoor piping 6 via a flexible gas pipe 5. And indoor piping 6 is branched off and connected to various combustion devices 7 installed indoors. Also gas pipe 5 Valves 8 and 9 are provided at the outlet of the pipe and the indoor pipe 6, respectively.

0003 The alarm 10 is installed at a predetermined position such as an indoor wall, and is connected to an electric light (not shown). connected to the line. In addition, the signal line 11 of the alarm 10 passes through the wall 12 and connects to the outdoors. It is taken out, extended along the gas pipe 5, and connected to a cutoff valve (not shown) of the gas meter 4. It is continued. When the alarm 10 detects a gas leak, it will sound an alarm such as a buzzer. At the same time, the detection signal is transmitted to the shutoff valve via the signal line 11, and the shutoff valve is activated. It is supposed to close.

0004

[Problem that the idea aims to solve]

However, according to the conventional alarm signal extraction structure configured as above, Not only does it take time and effort to route the signal line 11 indoors, but it also When installing the alarm 10 on an object, the signal line 11 must be routed along the wall. Otherwise, the appearance becomes unsightly. Furthermore, at the part where the signal line 11 penetrates the wall part 12, However, there are problems such as the need to perform waterproofing and appearance treatments on the inside and outside. there were.

[0005] Therefore, the purpose of this invention was to solve the above-mentioned problems. To provide an alarm signal extraction structure that does not require running wires and has an excellent indoor appearance. be.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, this invention is based on a gas leak alarm installed indoors. The signal output structure of the alarm transmits the detection signal emitted from the gas meter to the gas meter's shutoff valve. Therefore, the detection signal emitted from the alarm is transmitted through the existing electric light line installed indoors. and is configured to transmit the information to the shut-off valve, thereby activating the shut-off valve. There is.

[0007]

[Effect]

According to the above configuration, the detection signal emitted from the alarm is sent to the gas via the existing power line. Since the signal is transmitted to the meter's shutoff valve, there is no need to install a separate signal line, making construction easier. This can improve the indoor appearance.

【Example】

An embodiment of this invention will be described below with reference to the drawings.

[0009] FIGS. 1 and 2 show the configuration of an embodiment of this invention. In these figures, Figure 3 The parts corresponding to the parts of the conventional example shown in are shown with the same reference numerals, and their explanations are given as appropriate. Omitted.

0010 FIG. 1 shows only the main parts related to this invention. The alarm 10 receives the detection signal. Therefore, a transmitting unit 21 that emits a high frequency signal is connected, and the transmitting unit 2 The output side of 1 is connected to a power line 22 that supplies power to the alarm 10.

[0011] On the other hand, on the outside of the wall part 12, there is an outdoor electrical outlet, which is a terminal for lighting the outdoors. The outdoor outlet 23 is connected to the electric light line 22. Further, a receiving unit 25 is connected to the outdoor outlet 23 via a plug 24. The receiving unit 25 is sent from the transmitting unit 21 via the power line 22. The high-frequency signal generated activates a shutoff valve (not shown) built into the gas meter 4. It is designed to output a signal.

0012 To further explain in detail with reference to FIG. 2, the alarm 10 detects a gas leak. This detection signal drives the transmitting unit 21 to send out a high-frequency signal at a predetermined frequency. issue a number. This high frequency signal connects the power line 22, outdoor outlet 23, and plug 24. The received signal is transmitted to the receiving unit 25 via the receiving unit 25. Receiving unit 25 receives high frequency signals A signal is issued to close the shutoff valve built into the gas meter 4.

[0013] According to this embodiment, the detection signal emitted by the alarm 10 is transmitted via the existing power line 22. Since the signal is transmitted to the shutoff valve, there is no need for a signal line, and construction is easy and can be done both indoors and outdoors. Improves perspective.

[0014]

[Effect of the idea]

As explained above, according to this invention, gas leaks emitted from indoor alarms can be detected. The detection signal is transmitted to the gas meter's shutoff valve via the existing power line. This eliminates the need for signal lines, making construction easier and improving the interior appearance.
