The upper end and the lower end of the power distribution cabinet body 1 are respectively provided with an inlet pipe and an outlet pipe, and the inlet pipe and the outlet pipe are sealed by a sealing rubber sleeve and the like after the inlet pipe is led into and led out of a lead. AC220V relays at relays JK1, JK 2. The AC-DC module D1 is a module for converting AC power to DC power of 12V. Battery H is a 12V, 5Ah battery. The ponding sensor D2 is a brand RISYM/wife rain sensor module, which is provided with two power input ends and a signal output end, wherein the signal output end outputs power when the detection head detects water, and otherwise, the signal output end does not output power. The audible and visual annunciator D3 is an audible and visual annunciator finished product of the model OS 831.
As shown in fig. 1 and 2, the detection switch F1 is a self-resetting normally-closed contact button type power switch, a button of the control switch F1 is positioned outside the rear end of the cabinet body, the power distribution cabinet body 1 is installed behind a wall surface, and the button of the control switch F1 and the wall surface are in contact with an internal movable contact and a static contact to open. The height of the water accumulation sensor D2 (the probe is positioned at the upper part) is lower than the height of the upper end of the mounting groove 101. The power supply detection circuit mechanism comprises two relays JK1 and JK2 which are connected through wiring of a circuit board, and a normally open contact end of the first relay JK1 is connected with a control power input end of the second relay JK 2.
As shown in fig. 1 and 2, after the AC-DC module D1 is powered, the 3-pin and 4-pin power supplies of the AC-DC module D1 output 12V and enter the storage battery H (the storage battery H is charged, so that even if the power supply circuit is powered off, the power supply detection circuit mechanism, the detection switch F1, the water accumulation sensor D2 and the like can be electrically operated), the power supply detection circuit mechanism, the detection switch F1 and the power supply input end of the water accumulation sensor D2.
