As a way to illuminate the fire hydrant can be considered to have a flashlight in the fire hydrant, there is a problem that is unsuitable for one-person fire extinguishing with the risk of loss and periodic battery replacement. As another method, an emergency lighting lamp may be installed, but there are disadvantages in that the investment cost is excessive and outdoor installation is impossible.

Accordingly, the present invention implements an illumination light in the fire hydrant by installing a lighting lamp that lights when the door of the fire hydrant is opened in the fire hydrant.

1 is a general state of the installation of a fire hydrant, Figure 2 is a configuration of a fire hydrant lighting device is installed in the fire extinguisher in the fire hydrant in accordance with an embodiment of the present invention.

In constructing a fire hydrant, as mentioned in the section [Background Art of the Invention], other types of transmitters (P-type and R-type transmitters), a position indicator, and an operation indicator are essential elements, and are mainly shown in FIG. It is installed in the upper part of the fire hydrant box (2).

In Fig. 1, reference numeral 4 denotes another type of transmitter, " 6 " a position indicator, and " 8 " an operation indicator.

In the construction of a fire hydrant, the position indicator 6 is a red light, mainly attached to the upper part of the fire hydrant box 2, and can be easily identified at any place within 10m from the point of attachment. Similar to the position indicator 6, it is a red light and indicates the start of the pressurized water transmission device.

The position indicator (6) should prevent the occurrence of disconnection, remarkable luminous flux change, current change, etc., even when the voltage which is 130 percent of the commercial voltage is continuously applied for 24 hours, and the load of the indicator light (6) (8) It is not simple to install a separate lighting lamp in the fire hydrant (2) to maintain the power supply so that the voltage drop due to the present within the prescribed range.

In the embodiment of the present invention, as shown in Figure 2, the lighting lamp 12 that illuminates the compartment chamber 14 is installed on the upper side of the hydrant box 2, the lighting lamp 12 is the hydrant box door ( It is implemented as a start type that lights up only when 10) is opened so that there is no problem in power maintenance. In the event of a fire, the lighting lamp 12, which is activated immediately after the fire hydrant box 10 is opened, lights up an angle valve (watertight) 16 and a fire hose 18 in the compartment 14 of the fire hydrant box 2. ), Helps to more quickly and accurately find and use the nozzle (window) 20, the fire hydrant box door 10 continues to open after a certain period of time based on the timer 30 equipped in accordance with the present invention. Even though the lighting lamp 12 is turned off, the consumption of emergency power such as the battery 26 is reduced as much as possible.

3 is a circuit block diagram of a fire hydrant lighting device according to an embodiment of the present invention, the components are supplied with commercial power (220V AC), an example of emergency power supplied as the commercial power supply is cut off in the event of a fire The storage battery 26 can be provided. Emergency power Other examples include self-generators or emergency power receiving equipment.

The power supply unit 22 provides a DC power source of a driving voltage (for example, 24V) suitable for each unit by using an external commercial power source or an emergency power source. The other type transmitter 4, a position indicator 6, a start indicator In addition to (8), the lighting lamp 12 of the present invention also operates by receiving a direct current power provided from the source supply section 22.

The charge control unit 24 is a circuit unit for charging the storage battery 26 using a commercial power source, and the storage battery 26 charges the commercial power as a supply source. In the hydrant structure, the charge capacity of the storage battery 26 is preferably about 20 minutes.

The lighting lamp 12 forms a bracket 13 between the upper side door of the fire hydrant box 2 and the fire hydrant box door 10, which is a hinged door for the inner compartment 14, located below and installed on the bracket 13. Is suitable. Bracket 13 may be configured integrally at the time of manufacturing the fire hydrant (2), it may be mounted separately in the case of the existing fire hydrant.

The lighting lamp 12 is preferably composed of a high-brightness LED lamp with low power consumption, and the LED lamp has a voltage drop of 3 to 5 V in the case of an LED chip, such as a position indicator (6) and a start indicator (8). Even when considering the voltage drop of the power supply management, there is no problem, by connecting two LED lights (L1) (L2) constituting the lighting lamp 12 in parallel can increase the brightness of the interior compartment 14. The LED lamps L1 and L2 are preferably 2W class LEDs.

In the present invention, since the lighting lamp 12 is always operated, there may be a problem in power supply management, so that the lighting lamp 12 is turned on only when the fire hydrant door 10 is opened, and the detection sensor 32 and A sensing switch 34 is provided.

The detection sensor 32 detects the opening and closing of the hydrant box door 10, and the detection switch 34 switches to operate according to the detection of the detection sensor 32 to illuminate the commercial power or the emergency power of the power supply unit 22 with an illumination lamp. Optionally connect to (12). The sensing switch 34 is turned on when the sensing sensor 32 detects the opening of the fire hydrant door 10 so that the power of the power supply 22 is supplied to the lighting lamp 12.

The detection sensor 32 and the detection switch 34 is preferably configured as a limit switch of the N.C (normal close) contact. N.C contact limit switch is normally closed when the contact is closed (on) and open when it is sensed (off). It is not circuit-safe even when sensor breakdown or disconnection occurs.

In the present invention, after the fire hydrant box door 10 continues to be opened, the lighting lamp 12 is turned off even though the fire hydrant box door 10 is opened to save emergency power after providing lighting to be convenient for the user to use the fire hydrant. Implement

To this end, the present invention uses a timer 30, and includes a timer source signal generator 28 so that the timer 30 can operate even in an emergency power state.

The timer 30 preferably operates by using a commercial power frequency (the domestic commercial power frequency is 60 Hz), and a timer value for counting the expiration of the timer may include a timer value input unit 30a such as a dip switch. Implementations that can be controlled through this are also possible. The timer value is preferably set in the range of 30 seconds to 30 minutes, more preferably in the range of 3 to 20 minutes in consideration of the use of fire hydrants in the event of fire.

If the timer 30 operates using a commercial power frequency, most of the commercial power supply is automatically cut off when a fire occurs, so the timer 30 may not be operated. In order to prevent this, the timer source signal generator 28 ).

The timer source signal generator 28 provides a clock signal so that the timer can count using the emergency power supplied from the battery 26 when the supply of commercial power is stopped. The timer source signal generator 28 has the same frequency as the commercial power frequency. It is desirable to generate a clock signal.

When the timer source signal generator 28 generates the timer source signal, the timer 30 can operate even if there is no commercial power frequency to count the time. According to the expiration of the timer 30, the sensing switch 34 turns off the power supplied to the lighting lamp 12 to turn off the lighting lamp 12.

In the event of a fire, especially when a fire occurs at night, the commercial power is automatically cut off and the surroundings may be dark, so it is not easy to find a fire hydrant for the early suppression of the fire and to quickly use the fire hydrant equipment.

In the case of tunnel fire, the smoke emission is slower than the discharge speed of the building, so the smoke is accumulated inside, which can reduce the psychological state of the people, and it is not easy to use the outdoor fire hydrant at night due to the fire.

However, as in the present invention, when the movable lighting lamp 12 is installed in the fire hydrant box 2, the bright light of the lighting lamp 12 turned on when the fire hydrant box 10 of the fire hydrant box 2 is opened to the user. In addition to calming down, the fire hose 18 and the nozzle (window) 20 mounted in the fire hydrant box 2 are taken out calmly, and the knob of the angle valve 16 is turned to turn the angle valve ( After opening 16) hold the nozzle (20) to help deploy the fire hose (18) to the fire. It is also very useful for tidying up the post fire hose (18).

When the user opens the hydrant box door 10, the detection sensor 32 detects this and turns on the lighting lamp 12, which is an LED lamp, through the detection switch 34, and the fire hydrant box 2 turns on the lighting lamp 12. An angle valve (water drain) 16 in the interior, a fire hose hanger on the fire hose hanger in the compartment interior 14, or a fire hose 18 loaded in the interior compartment, and a nozzle (pipe window) connected to the tip of the fire hose 18 ) Will be visible to the user.

As a result of the present inventor performing the development test of the fire hose 18 before and after the installation of the lighting lamp 12 of the present invention, there was an average time reduction effect of 10 to 20 seconds, and the fire hose 18 before and after the installation of the lighting lamp 12 was arranged. As a result of performing the trimming test, it was confirmed that there is a time reduction effect of 30 seconds to 1 minute and 30 seconds on average.

As a fire line (time standard) for extinguishing a fire, the oil fire is about 70 seconds, the fibrous fire is 150 seconds, the wood fire is 300 seconds, and so on. The first two minutes of the fire is very important and the lighting is Such a time shortening effect through the lighting of the lamp 12 is quite effective in prematurely extinguishing the fire.

Even if the user does not close the fire hydrant door 10, the timer 30 automatically turns off after a certain period of time, so it is not a problem for the maintenance of emergency power, and the user has finished extinguishing and the limit mounted on the fire hydrant box 2 When using the switch or close and open the fire hydrant box door (10) again, the lighting lamp (12) is turned on again helps to clean up after the fire hose.
