[0021] Working principle: In this embodiment, the present invention also proposes a method for using an automatic control safety distribution box for preventing electric shock, comprising the following steps: Step 1: First, install the inner shell 13 against the inner side of the outer shell 2. The setting of the inner shell 13 made of insulating material can maintain a high explosion-proof ability under the support of the outer shell 2, and cooperate with the inner shell 13 to isolate the inner shell 13 from the outer shell 2 to prevent the components in the inner shell 13 from leaking and conducting electricity to the metal outer shell 2. Then, slide and adjust the movable mounting plate 15 so that the position of the movable mounting plate 15 can be more convenient for the installation and fixation of electronic components. Then, the movable mounting plate 15 is tightened and fixed by the cooperation of the clamping bolts and the sliding grooves, and then the components are fixed and installed. The insect-proof ventilation blocks installed on both sides of the outer shell 2 can ensure the ventilation state of the device while preventing insects from entering the device and affecting the normal operation of the components in the device. Step 2: Then, lead wires from the components to connect the zero block 11 and the grounding block 16. The grounding wire 9 connected to the grounding block 16 is buried underground to form a leakage protection structure. Then, the rotating motor is started to lower the blocking net 6, and the first abutment plate 20 is pressed down through the blocking net 6, so that the first abutment plate 20 presses down the first spring 22 and abuts against the abutment switch 23. The setting of the blocking mechanism can block the circuits and components in the device when the staff opens it, and warn the staff to operate safely, so as to prevent the cover plate 3 from being opened abnormally and accidentally touched by others; Step three, then close the cover 3. The closing of the cover 3 will cause the second abutting plate 29 to be pushed open by the second spring 30, thereby disconnecting the conductive connection between the abutting conductive block on the second abutting plate 29 and the detection alarm device, thereby stopping the working state of the detection alarm device. The setting of the alarm block can make the abutting conductive block abut against the detection alarm device in the alarm block when the cover 3 is opened, so as to detect the current and voltage of the zero block 11, and when a large change occurs, a radio alarm is issued to convey it to the supervisor, and the alarm block is disconnected when the cover 3 is closed, thereby extending the working time of the alarm block; Step four, finally, during maintenance and inspection, first open the cover 3. When the cover 3 is opened, the detection alarm device starts to detect the current and voltage of the device under the tension of the connecting wire 7. At this time, the staff can conduct a simple observation and inspection of the inside of the device through the blocking net 6. When maintenance is required, push to unlock the fixation of the buckle 17 and the slot 12, and start the rotating motor to rotate the shaft to retract the blocking net 6 to prevent the blocking net 6 from hindering the staff's maintenance. When the blocking net 6 is opened, the delayed monitoring box 8 is automatically started. The setting of the delayed monitoring box 8 can make the first abutment plate 20 disengage from the abutment of the abutment switch 23 after the blocking net 6 is disengaged, thereby starting the delayed alarm device in the delay monitoring box 8, and sound an alarm after a certain period of time and make the warning light 21 light up. After the maintenance and inspection is completed, the device is restored and closed again, and the use of the device ends.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
