The box door 12 is provided with a prompting lamp 6, and the prompting lamp 6 is electrically connected with the controller 5.
The working process of the invention is as follows:
1) When electric power workman overhauls and finishes, need close anti-electricity-theft ammeter box:
first, the door 12 is directly closed. At this time, the elastic piece 32 is located at the top end of the curved portion 391 of the two blocking pieces 39 and does not enter the passage yet. The distributor uses the mobile phone or the computer to communicate with the controller 5 through the signal transceiver 4, so that the electromagnet 33 is electrified and attracted with the permanent magnet 36, the elastic sheet 32 is driven by the magnetic force to pass through the notch to enter the channel, and the first contact 34 and the second contact 37 are connected in an overlapping manner. During the time that the resilient piece 32 passes through the notch, the bent portion 391 quickly deforms slightly and then returns to its original position, and makes a sound. When the first contact 34 and the second contact 37 are overlapped, the warning lamp 6 is kept on. Finally, the door 12 is locked by the door lock 2.
2) When the electricity stealing prevention electric meter box needs to be opened by an electric power worker:
firstly, the electric power worker communicates with the controller 5 through the signal transceiver 4 to power off the electromagnet 33, and then unlocks and opens the door 12.
3) When the electricity stealing prevention electric meter box is maliciously opened:
when the door is violently opened, the first contact 34 is separated from the second contact 37, the indicator light 6 is turned off, the electromagnet 33 is separated from the permanent magnet 36, and the elastic sheet 32 leaves the channel. Since the controller 5 does not receive an unlocking instruction from a terminal such as a mobile phone or a computer, but the first contact 34 is disconnected from the second contact 37, the controller 5 immediately notifies the power worker through the signal transceiver.
According to the invention, the door opening detector is arranged between the box body and the box door of the electric meter box body, whether the box door is illegally opened or not is detected in real time, once the door lock is violently damaged, the first contact and the second contact are disconnected in the forced opening process of the box door under the premise that the controller does not receive a door opening instruction, so that the abnormal opening condition of the electric meter box body is judged, and an electric power worker is informed to process as soon as possible; the tolerance of the first contact and the second contact to slight vibration is reduced by the magnetic attraction of the electromagnet and the permanent magnet and the cooperation with the elastic sheet; through the arrangement of the blocking piece, the blocking piece is matched with the electromagnet and the permanent magnet, and the slight sound generated when the blocking piece is rapidly deformed is utilized for an electric power worker outside the electric meter box body to judge whether the elastic piece is installed in place or not, and in addition, the connection stability between the first contact and the second contact after the door is closed can be further enhanced; through setting up support frame and adjusting bolt, the position adjustment of permanent magnet and second contact of being convenient for.
The above embodiments are illustrative of the present invention, and are not intended to limit the present invention, and any simple modifications of the present invention are within the scope of the present invention.
