At the same time, the camera 708 cooperates with the components on the circuit board 701 to achieve the effect of dynamic recognition, so that the instantaneous image is sent to the cloud through the network to achieve a warning effect. At the same time, the speaker can communicate remotely and issue an alarm to improve the safety protection performance of the electric meter 2. Through the protection component 8, when the component is not working, the protection plate blocks the keyhole 4, thereby preventing the lock 911 inside the keyhole 4 from being exposed to the outside. The phenomenon that the box cover 3 of the electric meter 2 is easily opened by external means can be solved by the lock component 9, which can cooperate with the protection component 8. The lock head 911 can be moved while the protection frame 805 is moved, so as to facilitate the maintenance personnel to remove the box cover 3 from the outside.

[0047] The specific configuration and functions of the anti-theft component 7, the protection component 8, the locking component 9 and the installation component 10 are described in detail below.

[0048] like Figure 2 and Figure 3 and Figure 4 as well as Fig.11As shown, the anti-theft component 7 also includes a storage module 702, which is welded on the surface of the circuit board 701. The surface of the circuit board 701 is respectively welded with a warning module 711, a communication module 703 and a processing module 705. The input end of the processing module 705 is connected to the output end of the camera 708, and the output end of the processing module 705 is respectively connected to the input ends of the communication module 703, the storage module 702 and the warning module 711. The camera 708 is fixedly connected to the surface of the electric meter 2, and the warning module 711 is welded on the surface of the circuit board 701. A plurality of LED lights 707 are fixedly installed on the surface of the electric meter 2 relative to both sides of the camera 708. A cover plate is installed on the surface of the camera slot 5, and the cover plate is transparent glass. A first spring 709 is placed inside the plug post 1003, one end of the first spring 709 is fixed inside the plug post 1003, and a first sensor 710 is welded on the other end of the first spring 709. A transformer is welded on the surface of the circuit board 701. The inner cavity of the electric meter 2 is relative to A battery 706 is fixedly connected to the top of the circuit board 701, and the output end of the battery 706 is connected to the input end of the circuit board 701. The processing module 705 on the circuit board 701 is a processor, the acquisition module is a camera 708, which is used to monitor the environment outside the electric meter 2 in real time, the warning module 711 is a speaker, which is used to remotely transmit audio and issue alarm audio, the storage module 702 is a memory, which is used to store the information collected by the camera 708, and the communication module 703 is a 4G network module, which is used to transmit the information inside the storage module 702 to the cloud through the network, so as to facilitate remote related personnel to view. During the operation of the component, if the box cover 3 is squeezed, the first sensor 710 inside the mounting hole 6 will be subjected to the change in the elastic force of the first spring 709 to generate a corresponding electrical signal, thereby enabling the alarm module to work and issue an alarm. At the same time, the camera 708 cooperates with the LED light 707 to capture an instantaneous image and send it to the cloud through the communication module 703.

[0049] like Figure 2 and Figure 5As shown, the protection assembly 8 also includes a moving frame 803, the inner wall of the moving frame 803 is threadedly connected to the bolt rod 802, the side wall of the moving frame 803 is fixedly connected to a rectangular box 804, the inner wall of the rectangular box 804 is slidably connected to a protection frame 805, the inner wall of the rectangular box 804 is fixedly connected to a fixing rod 810, the fixing rod 810 is connected through the surface of the protection frame 805, the two ends of the second spring 807 are respectively fixedly connected to the protection frame 805 and the rectangular box 804, and the side wall of the protection frame 805 is fixedly connected to a locking ring 811. When the personnel need to open the box cover 3, the remote personnel will send a remote instruction, at this time, the rotation of the motor 801 will drive the bolt rod 802 to rotate on the inner wall thread of the moving frame 803, thereby driving the rectangular box 804 to move with the protection frame 805, when the rectangular box 804 moves to a suitable distance, the position of the locking ring 811 will be aligned with the keyhole 4, exposing the lock head 911, so as to facilitate the personnel to rotate the lock head 911 later.

[0050] A third spring 808 is welded to the other side of the second sensor 806, and the other end of the third spring 808 is fixedly connected to the protection frame 805. When no maintenance is performed, an outsider forcibly removes the protection frame 805 through the keyhole 4 to expose the lock 911. The deformation of the second spring 807 connected to the protection plate will cause the second sensor 806 to generate an electrical signal, causing the alarm module to sound an alarm, and the subsequent principles are the same as described above.

[0051] A second spring 807 is sleeved on the surface of the fixed rod 810, a second sensor 806 is fixedly connected to the side wall of the rectangular box 804, transverse grooves 812 are provided on the surfaces of the protective frame 805 and the locking ring 811, a limiting rod 809 is penetrated and connected to the surface of the movable frame 803, and one end of the limiting rod 809 is fixedly connected to the motor 801. When an internal component fails and the box cover 3 cannot be opened, the personnel can use the horizontal lines 812 on the protective frame 805 and the lock ring 811 to forcibly move the protective frame 805, thereby exposing the lock head 911 and achieving the purpose of removing the box cover 3. The setting of the horizontal lines 812 is to increase the friction between the contact object and the protective frame 805 to prevent the protective frame 805 from being unable to move due to its smooth surface. At the same time, the setting of the second spring 807 can make the protective frame 805 be affected by the elastic force of the second spring 807, so that the protective frame 805 can always be tightly attached to one side of the rectangular box 804, preventing the movable frame 803 from being easily removed, increasing the difficulty of removal, and improving the safety protection performance of the electric meter 2 to a certain extent.

[0052] like Figure 2 and Figure 5 and Figure 8 as well as Fig.11As shown, the lock assembly 9 also includes a toothed chain 901, which is rotatably connected to the inner wall of the inner cavity of the electric meter 2, and a moving column 903 is slidably connected to the inner wall of the limit frame 902, and a receiving member 904 is slidably connected to the inner wall of the moving column 903, and a first gear 905 is fixedly connected to the surface of the receiving member 904, and a lock head 911 is fixedly connected to the side of the first gear 905 away from the receiving member 904, and second gears 906 are meshed on both sides of the toothed chain 901, and the second gear 906 penetrates and rotates on the inner cavity surface of the electric meter 2, and a lock frame 907 is fixedly connected to the end face of the second gear 906, and a connecting column 908 is fixedly connected to the surface of the box cover 3, and the connecting column 908 penetrates the inner cavity surface of the electric meter 2, and a lock groove 909 is provided on the surface of the connecting column 908, and the lock frame 907 and the lock groove 909 are mutually engaged. When the personnel need to remove the box cover 3, the personnel can insert the key into the keyhole 4 through the exposed lock 911 and press the lock 911 downward. The lock 911 will drive the first gear 905 to move toward the inner wall of the toothed chain 901. When the first gear 905 is meshed with the rack on the inner side of the toothed chain 901, the personnel can rotate the lock 911. The rotation of the toothed chain 901 will drive the second gear 906 to rotate, thereby driving the lock frame 907 to rotate. When the lock frame 907 is disengaged from the lock groove 909 on the connecting column 908, the personnel can remove the box cover 3 from the electric meter 2 to facilitate subsequent maintenance.

[0053] Connectors 912 are fixedly connected to both sides of the surface of the first gear 905, racks are distributed on both the inner and outer sides of the toothed chain 901, and a fourth spring 910 is placed inside the moving column 903, and both ends of the fourth spring 910 are respectively fixedly connected to the moving column 903 and the receiving member 904. When a person presses the lock 911, the lock 911 will be reset through the fourth spring 910 to avoid the contact between the lock 911 and the toothed chain 901 during the movement of the above-mentioned protection frame 805, thereby preventing the protection frame 805 from moving. The setting of the connector 912 facilitates the movement of the lock 911 when the above-mentioned protection frame 805 moves, so that the person can directly insert the key to remove the box cover 3.

[0054] like Figure 7 and Fig. 9 and Fig.10As shown, the installation component 10 also includes two installation boxes 1001, and the installation boxes 1001 are fixedly connected to the inner cavity surface of the back of the electric meter 2. Fixed blocks 1002 are fixedly connected to both sides of the inner wall of the installation box 1001. The inner wall of the fixed block 1002 is slidably connected to the plug post 1003. A slot 1010 is provided on the surface of the plug post 1003. Two semicircular blocks 1004 are fixedly connected to the inner wall surface of the installation box 1001. The interior of the semicircular block 1004 is slidably connected with a bayonet pin 1005. The size of the bayonet pin 1005 is compatible with the size of the slot 1010. The end face of the bayonet pin 1005 is fixedly connected with a straight groove bar 1007, and the surface of the straight groove bar 1007 is fixedly connected with a connecting line 1008. When installing the electric meter 2, the personnel can first fix the fixing plate 1 to the wall with screws, and at the same time, the plug 1003 will penetrate the back of the electric meter 2 and be inserted into the fixing block 1002. Before that, the personnel can pull out the connecting wire 1008 away from the electric meter 2, and the connecting wire 1008 will drive the locking pin 1005 to move. When the plug 1003 is fully inserted into the fixing block 1002, the personnel can loosen the connecting rope, and the locking pin 1005 will be reset by the spring force on the connecting rod 1006, so that the locking pin 1005 is engaged with the slot 1010, and the electric meter 2 is completely installed on the fixing plate 1.

[0055] Connecting rods 1006 are fixedly connected to both sides of the surface of the bayonet 1005. The connecting rods 1006 penetrate the surface of the sliding semicircular block 1004, and the other ends of the connecting rods 1006 are fixedly connected to the straight groove bar 1007. The setting of the connecting rods 1006 prevents the bayonet 1005 from rotating at an angle during the movement, thereby causing the bayonet 1005 to fail in the process of inserting the bayonet 1005 into the slot 1010, thereby reducing the difficulty of operation for personnel to a certain extent.

[0056] The inner wall of the installation box 1001 is fixedly connected with a pulley frame 1009 relative to the center position of the two fixing blocks 1002, and the connecting wire 1008 is wound around the pulley surface of the pulley frame 1009. The other ends of the two connecting wires 1008 are fixedly connected with a pull block 1011. The setting of the pulley frame 1009 can change the direction of the connecting wire 1008, so that it is convenient for personnel to operate the connecting wire 1008 from the inner cavity of the front face of the electric meter 2, thereby completing the process of operating the latch 1005, and at the same time, the pull block 1011 can facilitate the simultaneous operation of the two connecting ropes.

[0057] To sum up: the electric meter 2 is a device used to measure electrical variables and record electrical energy consumption. When personnel need to install the electric meter 2, they can insert the pin 1005 into the slot 1010 on the surface of the plug 1003 to achieve quick installation of the electric meter 2. When the entire assembly is in operation, the first sensor 710 and the second sensor 806 are both pressure sensors, which can not only detect the squeezing of the box cover 3, but also detect whether the protective frame 805 is forced to be pushed through the pressure sensor. When the above situation occurs, the camera 708 will cooperate with the LED light 707 to capture the instantaneous image and upload it to the cloud. When the electric meter 2 is used normally, the motor 801 will drive the protective frame 805 to move, so that the keyhole 4 and the lock head 911 inside the lock ring 811 are aligned. When the lock head 911 is turned, the lock frame 907 will disengage from the lock slot 909, so that the box cover 3 can be removed smoothly.
