[0037] The working principle of the embodiment is as follows:
[0038] When the box door 102 is opened by non-staff operation or other factors, the reset spring 301 in the compressed state quickly resets and rebounds, pushing the plug-in column 3 to move forward along the plug-in slot 205, until the reset spring 301 resets and rebounds to the natural state, at which time the sensing fitting block 302 corresponds to the position of the sensing slot 207, and the sensing fitting block 302 is in the sensing range of the proximity switch 208. When the proximity switch 208 senses the sensing fitting block 302, the sensing fitting block 302 feeds back a signal to the microcontroller 2016, and the microcontroller 2016 controls the timing module 2013 to start. When the timing value of the timing module 2013 is reached, the timing module 2013 feeds back a signal to the microcontroller 2016, and the microcontroller 2016 controls the buzzer 202 and the flashing light 105 to start. Through high-decibel buzzing and light warning, obvious regional warning is achieved around, avoiding people from approaching to prevent electric shock danger. At the same time, the microcontroller 2016 also controls the 5G module 2014 to wirelessly transmit an alarm signal to the monitoring center 2015, so that the staff in the monitoring center 2015 can know in time that the box door 102 of the power box 1 is accidentally opened, and personnel need to be sent to handle in time to avoid safety accidents;
[0039] When the staff normally opens the box door 102 for maintenance operation according to the regulations, in order to avoid false alarm, the staff can insert the embedded block 501 carried by himself into the matching plug-in slot 503, and then rotate the plug-in slot 502 through the inner hexagonal wrench to perform a rotating operation, so as to drive the abutting block 504 to rotate one hundred and eighty degrees along the rotating cavity 204, so as to rotate the cut surface 505 of the abutting block 504 to the rear side. At this time, the outer peripheral surface of the abutting block 504 does not abut on the key end of the on-off switch 209, and the on-off switch 209 automatically resets and is in an unpressed state, so that the proximity switch 208 associated therewith is also closed;
[0040] Further, since the matching plug-in slot 503 adopts an oval slot structure, non-staff cannot insert the embedded block 501 matching the structure size into the plug-in slot 503, and cannot twist and rotate the rotating block 5 in a short time to drive the abutting block 504 to rotate through common tools, so as to ensure that when the box door 102 is opened by non-staff operation, remote alarm can be realized in time;
[0041] When the staff maintenance is completed, the box door 102 needs to be closed, at this time the cut surface 505 of the pressing block 504 is turned to the rear side, so that the spring connecting piece 402 is in a compressed state under the pressing of the pressing surface of the pressing block 504 against the block 401, and the front end of the plug block 4 protrudes from the front end surface of the fitting block 2, so that the protruding block at the front end of the plug block 4 prevents the staff from closing the box door 102, so the staff needs to turn the cut surface 505 of the pressing block 504 to the front side, and when the cut surface 505 of the pressing block 504 is turned to the front side, the outer peripheral surface of the pressing block 504 presses the key end of the opening and closing switch 209, at this time the opening and closing switch 209 is in a pressed and started state, and the compressed spring connecting piece 402 is quickly reset and springs back under the pressing of the outer peripheral surface of the pressing block 504 against the block 401, thereby driving the block 401 to move backward along the reciprocating moving groove 2011, the front end of the plug block 4 is synchronously slid and accommodated in the plug hole 206, and it will no longer cause obstruction, and when the box door 102 is closed, the front end of the plug column 3 is also pressed and accommodated in the plug groove 205 under the pressing of the box door 102, at this time the sensing fitting block 302 is out of position with the sensing groove 207, and the sensing fitting block 302 is not in the sensing range of the proximity switch 208, so as to avoid false alarm.
