Description

Technology Field

[0001] The present invention relates to a fire extinguisher replacement cycle indicator, and more specifically, to a fire extinguisher replacement cycle indicator that detects the pressure gauge of a fire extinguisher to visually and audibly confirm the replacement cycle of the fire extinguisher and easily recognize the location of the fire extinguisher. Background Technology

[0002] Generally, in a fire extinguisher, powder and gas are compressed inside the main body, and when the user presses the handle to open the cap, the compressed gas pushes the powder out, and the powder is sprayed onto the flames to extinguish the fire.

[0003] Therefore, for the fire extinguisher to operate normally, the pressure inside the extinguisher body must be maintained at a constant pressure (7~98 kg / ㎠).

[0004] However, even if the pressure inside the fire extinguisher body is sufficiently charged, it may gradually decrease over time due to changes in the environment and drop below the pressure required for the fire extinguisher to operate normally.

[0005] A pressure gauge is installed on the fire extinguisher to check for such pressure changes.

[0006] FIG. 1 is an example illustration for explaining a general fire extinguisher. As shown in FIG. 1, a pressure gauge (20) is installed on one side of the fire extinguisher body (10) to check for changes in pressure, and the current pressure status of the fire extinguisher is displayed through a guide (21).

[0007] However, inspections of the pressure status of fire extinguishers are often neglected or even left unattended. Consequently, when a fire actually occurs and one attempts to use the extinguisher, it often fails to discharge the extinguishing agent at the proper pressure, leading to frequent failures in initial fire suppression.

[0008] In particular, since fire extinguishers are installed on the floor and a manager must come close to observe the pressure gauge (20) one by one, in high-rise buildings and large factories, it takes a lot of effort and time for a manager to observe the appropriate pressure of the fire extinguisher one by one, so there is a problem that it is difficult to check whether there is an abnormality in the pressure of the pressurized fire extinguisher.

[0026] Hereinafter, a preferred embodiment of a fire extinguisher replacement cycle indicator device according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0027] FIG. 2 is an exemplary diagram illustrating a fire extinguisher replacement cycle display device according to an embodiment of the present invention, FIG. 3 is a perspective view illustrating a fire extinguisher replacement cycle display device according to an embodiment of FIG. 2, FIG. 4 is a block diagram illustrating the configuration of a fire extinguisher replacement cycle display device according to an embodiment of FIG. 2, and FIG. 5 is an exemplary diagram illustrating the operation process of a fire extinguisher replacement cycle display device according to an embodiment of FIG. 2.

[0028] As shown in FIGS. 2 to 5, a fire extinguisher replacement cycle indicator (100) according to one embodiment of the present invention can be configured to detect the pressure gauge of the fire extinguisher to visually and audibly confirm the replacement cycle of the fire extinguisher and to easily recognize the location of the fire extinguisher.

[0029] To this end, the display device (100) may be configured to include a housing (110), a sensor unit (120), an LED display unit (130), a control unit (140), a power supply unit (150), and an alarm unit (160).

[0030] The housing (110) is configured to be detachably attached to the fire extinguisher and may be composed of a semicircular member so as to be in close contact with the outer surface of the disc-shaped pressure gauge (20).

[0031] Additionally, the housing (110) may be formed so that one side is open and is configured to be in close contact with the pressure gauge (20), and the other side may be configured to be spaced apart from the pressure gauge (20) at a certain distance so that the sensor unit (120), LED display unit (130), control unit (140), power supply unit (150), and alarm unit (160) are installed.

[0032] Additionally, the housing (110) may have a plurality of flanges (111) formed at regular intervals on the radially inner side of one end portion that is in close contact with the pressure gauge (20).

[0033] The housing (110) is press-fitted to at least a portion of the outer circumference of the pressure gauge (20) through the flange (111), thereby allowing the housing (110) to be fixed to the pressure gauge (20).

[0034] Additionally, the housing (110) may be further provided with a magnet (112) between the flanges (111) so that it can be more firmly fixed through the attractive force of a magnetic field between the magnet (112) and the pressure gauge (120).

[0035] The sensor unit (120) is installed on the other side of the housing (110) and can detect the position indicated by the indicator (21) on the pressure gauge (20) of the fire extinguisher.

[0036] The sensor unit (120) may be configured as a proximity sensor that is installed facing each other at a certain distance from the pressure gauge (20) and detects changes in the position of the indicator (21).

[0037] The sensor unit (120) can detect the position of the guide (21) by receiving the light reflected from the guide (21) using light, and can be composed of a pair of light-emitting and light-receiving units.

[0038] That is, the sensor unit (120) may be composed of a first sensor (121) that detects a first display area (22) of the pressure gauge (20), a second sensor (122) that detects a second display area (23), and a third sensor (123) that detects a third display area (24).

[0039] The position of the pressure gauge (20) indicator (21) can be detected by analyzing the light emitted from the first sensor (121), the second sensor (122), and the third sensor (123) to each display area (22, 23, 24) and reflected and received from the indicator (21).

[0040] The LED display (130) is installed in the housing (110) and is configured to turn on / off according to a lighting signal output from the control unit (140) in correspondence with the position indicated by the guide (21), and may light up a "green" light indicating a "normal state" or a "red" light indicating an "abnormal state."

[0046] Therefore, by detecting the pressure gauge of the fire extinguisher, the replacement cycle of the fire extinguisher can be checked visually and audibly, and the location of the fire extinguisher can be easily recognized.

[0047] In addition, it can be easily installed and used on already installed pressurized fire extinguishers.
