Monitoring device for power supply safety management

The utility model discloses a monitoring device for power supply safety management, which comprises a mounting seat and an alarm, the alarm is fixedly connected to the upper end of the mounting seat, a power connection terminal is fixedly connected to the middle position in the mounting seat, a power line is fixedly connected to the power connection terminal, and one end, far away from the power connection terminal, of the power line penetrates through the mounting seat. The beneficial effects of the utility model are that when the power supply is cut off, the electromagnet can release the adsorption of the current-conducting plate, so that the two ends of the current-conducting plate are in contact with the battery box and the terminal on the power supply line, and the current-conducting plate is prevented from being damaged. The battery is used for supplying power to the alarm, it is guaranteed that the alarm can be used normally, and in the power-on state, the electromagnet can be used for attracting the c
