The following is a description of the operation in the case of automatically inspecting the fire hydrant device S. To briefly explain the outline of the procedure, first, the forward tilting door 1 of the fire hydrant box 10 is opened to perform the door opening function. Then, the flow path is switched to the drain groove 65 by the three-way switching valve 61 to open / close the fire hydrant valve 11 to check the opening / closing function, and the water discharge function when the fire hydrant valve 11 is opened. Then, the forward tilting door 1 is closed, the door closing function is confirmed, and the process ends. At this time, if a person approaches the vehicle, an accident such as hitting the forward-tilting door 1 may occur. Therefore, while the indicator lamp 85 is blinking, the speaker 86 informs the danger during inspection by an acoustic alarm. Door opening: When the disaster prevention board 80 issues a door opening command to the inspection control unit 70, the inspection control unit 70 starts a motor (not shown) of the movable link unit 18 to move the movable link unit 18 as shown in FIG. Is moved in the direction of arrow A18. Then, the operating rod 17 rotates about the fulcrum 17a and pulls the rod 25 in the direction of the arrow A25, so that the latch 22 of the latch mechanism 20 is disengaged from the latch groove 21 and the forward tilting door 1 is tilted while slowly rotating, Open the door. At this time, the handle 4 also rotates in the direction of arrow A4 at the same time, and the state is the same as when the user pulls the handle 4.

The fire hydrant box 10 has a closure detection means 8
2, a closing limit switch (not shown) is provided between the closing door body 1 and the door body 1 being closed, and when the latch 22 is disengaged and the forward tilting door 1 starts to open, that is, the opening limit switch is turned off. And the latch 22

Further, the fire hydrant box 10 is provided with a fully open limit switch (not shown) between the fully open door body 1 as the open detection means 81 so that it is turned on only when the forward tilting door 1 is fully open.

A load sensor (not shown) of the motor of the movable link unit 18, for example, an ammeter measures the value of current flowing through the motor from the start of the motor until the latch 22 is released, and the measurement result is inspected and controlled. It is sent to the unit 70. The inspection control unit 70 compares the load required for the operation of unlocking the forward-tilting door 1 from the measured value, that is, the maximum current value of the measured value with the allowable range of the reference current value, and determines whether or not it is normal. to decide. This judgment (evaluation) is performed by the inspection control unit 70 as a result of the steering wheel operation.
Is stored in a storage unit (not shown) and sent to the control panel 80 of the disaster prevention center. Although an ammeter is used as the load sensor in the above, a voltmeter or a power meter may be used.

Further, the inspection control unit 70 has the closing detection means 8
2 as a closing limit switch and opening detecting means 81
Based on the respective signal of the open limit switch of
Regarding the opening operation of the forward tilting door 1, check the time from turning off the closing limit switch to turning on the opening limit switch. Here, the opening time of the forward-tilt door 1 should be abnormal when it does not open easily or when it opens all at once. Therefore, the obtained time is compared with a predetermined allowable range to determine whether it is normal or not. To judge. This judgment (evaluation) is also the result of the door opening function as the result of the steering wheel operation.
No. 0 is stored in a storage unit (not shown) and is sent to the control panel 80 of the disaster prevention center.

The completion of unlocking is judged by the inspection control unit 70 recognizing that the closing limit switch is off. In the case of the fire hydrant device which is not provided with the closing limit switch, the completion of unlocking is recognized by the movable link portion 18 of the normal fire hydrant door.
Measure the moving distance from starting to unlocking with a stroke measuring instrument, compare the measured values with this as a reference,
The unlocking may be completed when a predetermined stroke occurs in the movable link portion 18 while driving the motor of the movable link portion 18.

In the above description, the time required from immediately after unlocking to full opening is dealt with, but it may be determined whether or not the time required from motor start to unlocking to full opening is normal. Good. Further, for example, when a force for opening the fire hydrant door from unlocking to full opening is required, the operation status of the door body of the fire hydrant device is from the start of the motor of the movable link portion 18 to the fully opened state after unlocking. You may make it catch the temporal change of the door opening load of.

Water discharge inspection: The disaster prevention board 80 issues a water discharge inspection command to the inspection control unit 70 when it confirms that the door is open. The inspection control unit 70 drives the motor 62 to switch the three-way switching valve 61 to the inspection flow path 61b side, and also sends a switching completion signal to the disaster prevention board 80.

The disaster prevention board 80 issues a command for opening the fire hydrant valve 11 to the inspection control unit 70. The inspection control unit 70 uses the motor 56.
Is driven, and the operating portion 54 is slid to pull the wire 52. Then, the state becomes the same as when the user pulls the opening / closing lever 12, the fire hydrant valve 11 is opened, and the fire extinguishing water flows through the three-way switching valve 61 into the inspection flow passage 61b and is discharged from the discharge port 65. . At this time, fire extinguishing hose channel 6
Since 1a is closed, fire extinguishing water does not flow into the hose 95.

At this time, as the load sensor of the motor 56, for example, an ammeter measures the operation load required to open the fire hydrant valve 11, and the pressure sensor 63 measures the water discharge pressure due to the opening of the fire hydrant valve 11. , And sends each measured value to the inspection control unit 70. The inspection control unit 70 compares the measured value sent from it with the reference value to determine whether it is normal or not, and stores it as a valve opening function result in a storage unit (not shown). The water discharge pressure is compared with a design value to determine whether the measured value after a stable flow after a predetermined time has passed is normal, and is stored as a water discharge function result in a storage unit (not shown) of the inspection control unit 70. Each disaster prevention center disaster prevention board 8
Send to 0.

Preparation for closing the door: Next, the disaster prevention board 80 issues a water discharge stop command to the inspection control unit 70. The inspection control unit 70 drives the motor 56 in reverse to drive the operation unit 54 and the opening / closing lever 1.
After returning 2 to the original position and closing the fire hydrant valve 11, the motor 62 is driven to switch the three-way switching valve 61 to the fire extinguishing hose passage 61a. Even in the operation by the water discharge stop command, the operation load required for closing the fire hydrant valve 11 can be measured by the ammeter as the load sensor of the motor 56, and the inspection control unit 70 sets the same reference value as when the valve is opened. A comparison is made to determine whether it is normal, and the result is stored in a storage unit (not shown) as a valve closing function result and sent to the disaster prevention panel 80. It should be noted that the valve opening function result is required as an operation even with respect to the valve closing function result, and the valve closing function result may be omitted, or may be combined into a single opening and closing function result.

Door closing: The disaster prevention board 80 issues a door closing command. The inspection control unit 70 drives the motor 48,
The on-off valve 46 is opened. When the valve 46 opens, the primary side 45
Fire extinguishing water flows into the cylinder 41 and presses the piston 42. Then, the piston 42 slides in the direction of the arrow A42 to press the lower end portion 1a of the door body 1, the forward tilting door 1 rotates in the direction of the arrow A1 about the rotation shaft 1b, and the latch 22 moves into the latch groove 21. Engages and closes the door.

As with the opening of the door body, it is confirmed that the fully open limit switch is turned off when the forward tilting door 1 is moved away from the fully open state, and the closing limit switch is turned on when the forward tilting door 1 is closed, thereby confirming that the forward tilting door 1 is closed. At the same time, the closing operation is performed at the same time, for example, from the full opening to the full closing until the latch is locked or just before the locking, and the two switches are operated as the evaluation of the closing operation of the forward tilting door 1. You may decide the time between.

Also in this case, as in the case of opening the door body, the closing force is set so that the closing speed does not exceed a predetermined value so that the closing force does not unnecessarily forcefully close,
The time when the full-open limit switch is turned off when the forward tilting door 1 is separated from the fully-opened state and the time when the closing limit switch is turned on when it is closed are stored, and it is checked whether or not the difference is normal. The determination is made by the control unit 70. This determination (evaluation) may be made by first confirming that the forward tilting door 1 is closed, and is stored in the storage unit of the inspection control unit 70 as a closing confirmation result and sent to the disaster prevention panel 80 of the disaster prevention center.

The maintenance and inspection of the fire hydrant device S is completed as described above. However, when further maintenance and inspection of the fire hydrant device S is performed, the disaster prevention board 80 controls the inspection and control of other fire hydrant devices installed in the same manner as described above. A command is issued to the section 70 in order and an inspection is performed. In the above-mentioned maintenance and inspection procedure, a control command is sent from the disaster prevention board 80 to the inspection control unit 70 in a procedure in which the fire hydrant device S is normally operated.
The water discharge pressure measurement with opening and closing can be performed individually and, for example, as a procedure, the closing operation may be performed immediately after the forward tilting door 1 is opened, and then the fire hydrant valve 11
You may open and close. Further, in the above-mentioned maintenance / inspection procedure, control commands are sent from the disaster prevention board 80 to the inspection control unit 70 for each procedure, but the disaster prevention board 80 only sends a command to start inspection as a control instruction. , Inspection control unit 7
The control operation may be performed while 0 sequentially stores the inspection results, and finally all inspection results may be sent to the disaster prevention board 80. At this time, if everything is normal, it may be sent only that it is normal, and it suffices to send information indicating the abnormal portion at the time of abnormality. Furthermore, fire hydrant valve 1
It is disadvantageous that all of the fire hydrant devices perform the water discharge operation at the time of opening No. 1 at a time, and it is necessary to perform it for each one or a plurality of fire hydrant devices. It can be executed at almost the same time with S, and disaster prevention board 80
Thus, it is possible to combine the commands for all the fire hydrant devices S and the commands specified for each address or each group to advance the inspection operation. The operation of confirming the opening and closing of the door body may be the same as that of a fire extinguisher door, which will not be described in detail. As described above, the opening mechanism of the door body is not limited to the forward tilting door 1, and may be, for example, a biased lateral opening type door body.

A second embodiment of the present invention will be described with reference to FIG. The difference between this embodiment and the first embodiment (FIGS. 1 to 5) is that the self-pressing mechanism of the forward-tilting door utilizes winding by a wire. As shown in FIG. 6, a wire reel 101 driven by a motor 100 is provided in the upper part of the fire hydrant box 10, and a wire 102 of the wire reel 101 is guided through a guide roller 103 to a central portion 1f of the forward tilting door 1. Are linked to.

In this embodiment, when the disaster prevention board 80 issues a closing door command to the inspection control unit 70, the inspection control unit 70 causes the motor 1
00 to rotate the wire reel 70. Then, the wire 102 is wound up on the wire reel 101, and the forward tilting door 1 is pulled.
The door is closed by rotating in the direction of arrow A100 around b.
In such an automatic inspection function of the fire hydrant device S, when the disaster prevention panel 80 and each inspection control unit 70 perform signal transmission through a signal line (not shown), other devices and signal lines provided in the tunnel not shown in detail. May be used in common,
For example, when fire monitoring is performed by a flame detector,
The inspection control unit 70 of each fire hydrant device S and each flame detector may be connected to a common signal line.
