A plurality of horizontal heat dissipation holes 7 are opened on the rear side of the cabinet 1.

[0025] Specifically, the cabinet 1 is fixed to the top plate 3 and the base 2 by welding. The wall thickness of the opening on the front side of the cabinet 1 is consistent with the wall thickness of the base 2. The front side of the base 2 is higher than the height of the other sides. The alarm 5 is screwed on the upper end of the right side wall of the cabinet 1 through the mounting base. The wires of the alarm 5 pass through the wire groove opened on the top plate 3 and are connected to the controller 9.

[0026] like Figure 3 As shown, a moving groove 21 is provided on the upper surface of the front end of the base 2 , and the lower end of the sliding door 4 moves left and right along the moving groove 21 .

[0027] like Figure 2 As shown, the driving device includes a screw rod 23, a first pulley 25, a second pulley 27 and a belt 28. By setting up the driving device, it is convenient to drive the connected sliding door to move left and right. The screw rod 23 is rotatably installed in the movable groove 21, and the two ends of the screw rod 23 are rotatably installed in the movable groove 21 through the first bearing 24 respectively. The screw rod 23 is threadedly connected to the sliding door 4. The left side of the screw rod 23 is fixedly connected to the first pulley 25, and the first pulley 25 is transmission-connected to the second pulley 27 fixed on the motor 26 through the belt 28. The belt 28 passes through the position of the opening 22 opened on the side wall of the movable groove 21. The motor 26 is fixed on the bottom side of the base 2, and the output shaft of the motor 26 is rotatably connected to the second bearing 29 in the side wall of the base 2.

[0028] like Figure 6 As shown, the bottom side of the sliding door 4 is provided with a moving block 42 threadedly connected to the screw rod 23, so as to maintain a certain distance between the lower side of the sliding door 4 and the screw rod 23. When the screw rod 23 rotates, the sliding door 4 is driven to move left and right by the moving block 42.

[0029] During the operation of the motor 26, the second pulley 27 fixedly connected to the output shaft of the motor 26 rotates, and the second pulley 27 drives the first pulley 25 fixedly connected to the screw rod 23 to rotate through the belt 28, and then the first pulley 25 drives the screw rod 23 to rotate. At this time, the screw rod 23 drives the moving block 42 on the bottom side of the sliding door 4 to move.

[0030] like Figure 1 As shown, a fixing groove 31 is provided on the bottom side of the front end of the top plate 3, and an electromagnetic telescopic column 8 is provided in the fixing groove 31. By providing the electromagnetic telescopic column 8, the sliding door 4 is further reinforced when it is in a closed state.

[0031] like Figure 4 As shown, the electromagnetic telescopic column 8 includes an electromagnetic fixed iron core 81, a spring 82 and a clamping column 83. The bottom side of the electromagnetic fixed iron core 81 is fixedly connected to one end of the spring 82, and the other end of the spring 82 is fixedly connected to one end of the clamping column 83. The electromagnetic fixed iron core 81 is electrically connected to the controller 9.

[0032] like Figure 3 and Figure 5 As shown, a fixing hole 41 is provided at the upper end of the sliding door 4, and the card column 83 can be inserted into the fixing hole 41. When the sliding door 4 is in a locked state, the electromagnetic fixed iron core 81 is in a power-off state. At this time, the electromagnetic fixed iron core 81 is not magnetic. Under the elastic force of the spring 82, the card column 83 is inserted into the fixing hole 41. When the sliding door 4 is opened, the electromagnetic fixed iron core 81 is magnetic after being energized. At this time, the electromagnetic fixed iron core 81 overcomes the elastic force of the spring 82 through magnetic attraction to make the card column 83 disengage from the fixing hole 41; the motor 26 of the utility model adopts a stepping motor. After running a certain number of circles, the motor stops running, and the controller cuts off the power to the electromagnetic telescopic column. A ball 10 is installed on the upper surface of the right side of the base 2. The ball 10 is provided for the sliding groove 43 provided at the lower end of the sliding door 4 to move. By setting the ball 10, the sliding door 4 moves more smoothly, and a support point is added to the bottom side of the sliding door, so that the sliding door 4 is more stable during movement.

[0033] like Figure 1 As shown, a groove 11 is provided on the inner wall of the cabinet 1 opposite to the side wall provided with the strip hole, and the end of the sliding door 4 can be inserted into the groove 11, so that the sliding door 4 can be completely hidden in the cabinet 1 to prevent thieves from violently disassembling it from the edge.

[0034] In the specific implementation of the utility model, a power module is provided in the top plate 3, and the power module is connected to the municipal power supply circuit separately connected to the power metering cabinet. The controller 9 is connected to the motor 26, the NFC card reader module 6, the electromagnetic telescopic column 8 and the alarm 5 through wires or signal lines. The maintenance personnel are equipped with NFC cards or mobile phones with NFC functions. The NFC cards or mobile phones with NFC functions and the NFC card reader module are encrypted based on NFC technology. Each NFC card reader module and the NFC blockbuster or mobile phone with NFC function equipped by the maintenance personnel have a unique NFC key; when the card is attached to the NFC card reader module 6 for the first time or the second time, the corresponding motor 26 can start and stop running, the electromagnetic telescopic column 8 is powered on or off at the same time, and the card column 83 is retracted or extended into the top plate 3. If the NFC card reader module 6 fails to recognize the card for multiple times, the alarm will sound for several seconds (it can sound for 3 seconds or 5 seconds) and stop; the connection method and working principle of the power module, the controller 9, the motor 26, the electromagnetic telescopic column 8, the alarm 5 and the motor 26 are all prior art and will not be repeated here.

[0035] The working process of an electric power metering cabinet with anti-theft function provided by the utility model is as follows:

[0036] Under normal circumstances, the sliding door 4 completely closes the opening on the front side of the cabinet 1, and the clamping column 83 is inserted into the fixing hole 41. At this time, the sliding door 4 is in a locked state. Since the sliding door 4 is a side-opening door, other personnel cannot pry the door open, thereby realizing the anti-theft control of the power metering cabinet;

[0037] When it is necessary to perform on-site meter reading or maintain the meters and circuits in the cabinet 1, the maintenance personnel use the NFC card or the mobile phone with NFC function to stick the NFC card reader module 6. After the information of the NFC card reader module 6 is successfully matched, the matching success information is sent to the controller 9. The controller 9 starts the motor 26 and energizes the electromagnetic fixed iron core 81 at the same time. The electromagnetic fixed iron core 81 has magnetism after being energized, and the card column 83 is adsorbed and separated from the moving block 42. The motor 26 drives the sliding door 4 to move to the right. When the motor 26 stops running after running a certain number of circles, the sliding door 4 moves to the rightmost end, and the opening on the front side of the cabinet 1 is opened; when the NFC card or the mobile phone with NFC function is stuck to the NFC card reader module 6 for the first time, if the NFC card reader module 6 fails to match the information three times, the NFC card reader module 6 sends a matching failure information to the controller 9, and the controller 9 sends an alarm instruction to the alarm 5, and the alarm 5 alarms;

[0038] When the maintenance is completed, the maintenance personnel once again stick the NFC card or the mobile phone with NFC function to the NFC card reader module 6, and the information of the NFC card reader module 6 is matched successfully again, and the successful matching information is sent to the controller 9. After receiving the information of the second successful matching, the controller 9 first sends a reverse operation command to the motor 26 to drive the sliding door 4 to move to the left. When the motor 26 stops running after running a certain number of circles, the sliding door 4 moves to the far left end, and the opening on the front side of the cabinet 1 is closed. Then the controller 9 cuts off the power to the electromagnetic fixed iron core 81. After the electromagnetic fixed iron core 81 is powered off, it loses its magnetism, and the card column 83 loses its magnetic adsorption force. It moves downward under the elastic force of the spring 82 and inserts into the moving block 42 to lock the sliding door 4.

[0039] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
