る。 In Fig. 1, 1 is a priming tank, and priming tank 1
is provided with a water level gauge 2 for monitoring the water level, and when the water in the priming tank 1 falls, the water in the priming tank 1 is supplied to the fire pump 5 from the piping 3 via the check valve 4, and It is connected to an overflow pipe 14 via an electromagnetic valve 6 and a drain valve (manual) 12 which are provided in parallel with the piping 3 to drain water from the priming tank 1, and to drain the priming water to a water tank 7 storing fire extinguishing water. I have to. Further, a flow rate test pipe 8 is connected to the discharge side of the fire pump 5.
is provided with an electric valve 9 and a flow meter 10, and when the electric valve 9 is opened, fire extinguishing water from the fire pump 5 driven by a motor 11 is flowed into the flow rate test pipe 8, and the flow rate is measured with the flow meter 10. The actual flow rate test of the fire extinguishing pump 5 can be performed by

いる。 On the other hand, when automatic inspection of the priming tank 1 fails to detect a drop in the water level of the priming tank 1 due to a malfunction of the water level gauge 2, etc., priming water is no longer supplied to the fire pump 5, thereby extinguishing the fire in the event of a fire. This is done because there is a problem in which the pump cannot be started normally, and an automatic inspection control device (not shown) sends a control signal to the solenoid valve 6 installed in the piping 3 to open it, forcing water in the priming tank 1. When the water level in the priming tank 1 drops to a predetermined level, if the water level gauge 2 is normal, it detects a drop in the water level and sends out an alarm signal. If this is obtained, it is determined that the priming tank 1 is normal.

The priming tank 1 is provided with a water level gauge 2 for detecting the water level, and the water level gauge 2 sends out an alarm signal when the water level in the priming tank 1 falls below a predetermined level. Also,
A pipe 3 is connected to the bottom of the priming tank 1, and the pipe 3 is connected to an overflow pipe 14 via a manual drain valve 12.
It is also suspended in water tank 7. On the other hand, the pipe 3 is branched from the inflow side of the drain valve 12 and connected to the discharge side of the fire pump 5 via the check valve 4 . The fire pump 5 is driven by a motor 11, and the discharge side of the fire pump 5 is connected to a flow rate test pipe 8 that returns to the water tank 7. The flow rate test pipe 8 is equipped with an electric valve 9 as an opening/closing control valve and a flow meter 10. Placed.
Of course, the discharge side of the fire pump 5 is launched via the main pipe 15, and is connected to the sprinkler head via branch pipes connected to each floor.

(hereinafter referred to as CPU) 17, a ROM that permanently stores inspection processing programs, and temporarily stores inspection data.
The memory 18 includes RAM. CPU
An inspection signal is given to 17 from a clock unit or an operation section provided as an external device, and upon receiving this inspection signal, inspection processing control is executed according to a predetermined program. Also, CPU1
7, the water level gauge 2 of the priming tank 1 shown in FIG.
次に、第４図のフローチヤートを参照して本考
案による呼水槽の自動点検を説明する。 Next, automatic inspection of the priming tank according to the present invention will be explained with reference to the flowchart shown in FIG.

力するようになる。 First, the inspection control device 16 monitors whether or not an inspection signal is input in a discrimination block 20. When an inspection signal is input, the inspection control device 16 proceeds to block 21 and outputs a control signal to open the electric valve 9 provided in the flow rate test pipe 8. do. When the electric valve 9 is opened by this control signal, the water in the priming tank 1 is drained into the water tank 7 through the pipe 3, the check valve 4, and the flow rate test pipe 8, and the water level in the priming tank 1 is lowered. Therefore, if the water level gauge 2 installed in the priming tank 1 is operating normally, the water level in the priming tank 1 will reach the water level gauge 2 after a certain period of time after the electric valve 9 is opened.
The water level gauge 2 begins to output an alarm signal.

点検制御処理を終了する。 Therefore, in the flowchart of FIG. 4, the determination block 22 monitors whether or not an alarm signal is obtained from the water level gauge 2 within a predetermined time after the electric valve 9 is opened. When this occurs, it is determined that the water level gauge 2 is operating normally, and the process proceeds to block 23, where a control signal to close the electric valve 9 is output. When drainage of the priming tank 1 is stopped by closing this electric valve 9, the water level in the priming tank 1 rises due to the water supplied via the water supply solenoid valve 13, and exceeds the predetermined alarm water level. When the water level rises, the alarm signal is no longer sent from the water level gauge 2. Therefore, in the flowchart of FIG. 4, it is determined in the determination block 24 whether or not the alarm signal disappears within a predetermined time after the electric valve 9 is closed, and when the alarm signal disappears within the predetermined time, the water level gauge 2 The series of inspection control processing ends assuming that the is operating normally.

る。 On the other hand, if an alarm signal is not obtained within a predetermined time after the electric valve 9 is opened in the determination block 22, or if the electric valve 9 is not opened in the determination block 24,
If the alarm signal does not disappear within a predetermined time after closing the priming tank 1, it is determined that there is an abnormality in the water level gauge 2 of the priming tank 1, and the process proceeds to block 25, where an alarm is issued for the abnormality in the priming tank, and a series of inspections are carried out. Control processing ends.
