JP2000070396A - Gas pressure check of pressure accumulator type fire extinguisher - Google Patents

Abstract

PROBLEM TO BE SOLVED: To perform gas pressure check for all fire extinguishers in a remote place, by providing the extinguishers respectively provided with transmitters for sending a signal when a needle of an indication pressure gauge removes from a green zone, and by receiving the signal from each transmitter in a plurality of fire extinguishers to a central control portion, and identifying and displaying the signal for each fire extinguisher. SOLUTION: When a plurality of arranged pressure accumulator type fire extinguishers are centrally controlled by a central control room, each fire extinguisher is constituted so that, when gas leak occurs and a needle 1a of an indication pressure gauge 1 removes from a green zone 3, a pressure switch 2 actuates to cause a transmitter 4 to send a signal. The central control room is constituted so that, when it receives the signal from the transmitter 4, the room performs identification and display (for example, lights a lamp) responding to the extinguisher. Thereby, gas pressure check for each extinguisher can be performed in the central control room, and gas pressure of all pressure accumulator type fire extinguishers can be monitored by full time of 24 hours.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for checking gas pressure of an accumulator type fire extinguisher.

[0002]

When a pressure-accumulation type fire extinguisher is used for home use, the gas pressure can be checked immediately by looking at the indicating pressure gauge, because the pointer does not deviate from the green zone. In places where a number of accumulators are arranged, such as hospitals and nursing homes, it takes a great deal of time and effort to go to the installation location and look at the indicated pressure gauges one by one.

[0003]

According to the first aspect of the present invention, there is provided a method for checking gas pressure of a pressure accumulating fire extinguisher, wherein a plurality of pressure accumulating fire extinguishers are arranged, and an indicating pressure gauge is provided for each fire extinguisher. Each of the transmitters that emits a signal when the pointer deviates from the green zone is provided, and the central control unit receives the signal of each of the transmitters and identifies and displays it for each fire extinguisher. The gas pressure of all fire extinguishers can be checked immediately at the centralized control unit without having to go to and check the indicated pressure gauges one by one, and the Fire Defense Law requires that the gas pressure be checked by visual inspection. Is every 6 months, but can monitor gas pressure 24 hours a full time.

According to a second aspect of the present invention, there is provided a gas pressure checking method for an accumulator type fire extinguisher, in which a plurality of accumulator type fire extinguishers are arranged, and a pointer of an indicating pressure gauge of each extinguisher has a green zone. Wiring is performed so that an electric signal is output when the fire extinguisher is disconnected, and this wiring is connected to each of the fire extinguishers by each electric plug. Since the identification display is used, the gas pressure of all fire extinguishers can be checked immediately at the central control unit without going to the place where the fire extinguishers are installed and looking at each indicating pressure gauge one by one. The central control unit can also check the movement of the fire extinguisher due to theft, mischief, etc. due to the removal of the fire extinguisher or the actual fire.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 One embodiment of the present invention will be described with reference to FIG. FIG. 1 is a partial view showing the appearance of an accumulator type fire extinguisher.
Is a pressure switch (pressure detector) that operates when the pointer 1a of the indicating pressure gauge 1 goes out of the green zone 3, and 4 is a transmitter that transmits an operation signal of the pressure switch 2. Although not shown, a plurality of the pressure-accumulating fire extinguishers shown in FIG. 1 are arranged, and an identification display board for centrally controlling each fire extinguisher is provided in the central control room. When a signal from the fire extinguisher 4 is received, an identification display (for example, a lamp is turned on) can be made for each fire extinguisher.

When a gas leaks from a certain pressure accumulating type fire extinguisher and the pointer 1a of the indicating pressure gauge 1 deviates from the green zone 3, the pressure switch 2 is operated and a signal is output from the transmitter 4. The identification display panel lights up upon reception. It can be seen in the central control room that a gas leak has occurred in this lit fire extinguisher. In this way, the gas pressure of each fire extinguisher can be checked while staying in the central control room, and the gas pressure of all accumulators can be monitored 24 hours a full time.

Embodiment 2 One embodiment of the invention will be described with reference to FIG. FIG. 2 is a partial view showing the appearance of the accumulator type fire extinguisher. In the drawing, reference numeral 5 denotes a wiring connected to a centralized control room, and reference numeral 6 denotes an electric plug for connecting the wiring 5 to the pressure switch 2. In the figure, the same parts as those in FIG.

In this case, the operation of the pressure switch 2 depends on the wiring 5
As a result, an electric signal is transmitted to the identification display board, and is displayed for each fire extinguisher. When the electric plug 6 is removed, the disconnection can be identified in the central control room.
In the central control room, you can see that the fire extinguisher has been moved by theft or mischief, or that a fire has actually occurred.

[0009]

As described above, according to the first aspect of the present invention, a plurality of pressure accumulating fire extinguishers are arranged, and when the pointer of the indicating pressure gauge of each fire extinguisher is out of the green zone. Transmitters that output signals are provided, and the central control unit receives the signal of each transmitter and identifies and displays it for each fire extinguisher, so go to the installation location of the fire extinguisher and look at each of the indicated pressure gauges The gas pressure of all fire extinguishers can be checked immediately at the central control section without turning around, and the fire pressure law is required to check the gas pressure by appearance inspection, and this appearance inspection is every six months, but it is 24 hours The effect that the gas pressure can be monitored full time can be obtained.

According to a second aspect of the present invention, a plurality of accumulator-type fire extinguishers are arranged, and an electric signal is supplied to each fire extinguisher when the pointer of the indicating pressure gauge deviates from the green zone. And the wiring is connected to each of the fire extinguishers by each electric plug, and the centralized control unit receives the electric signal and identifies and displays each fire extinguisher. The central control unit can immediately check the gas pressure of all fire extinguishers without having to go to the installation location and look at each of the indicated pressure gauges one by one. In addition, the fire extinguishing due to theft, mischief, etc. can be performed by removing the electric plug from the fire extinguisher. The effect that the central control unit can also check the movement of the container or when a fire actually occurs is obtained.
