Description

Technical Field

[0001] This invention relates to the field of electrical cabinets, and more particularly to an electrical energy metering box with a security structure. Background Technology

[0002] The existing technology of electricity metering boxes has several shortcomings. First, in terms of physical security, traditional metering boxes expose the electricity meter, terminals, and all wiring completely when the cabinet door is opened, making them highly vulnerable to damage such as smashing, cutting, and sawing, as well as illegal wiring tampering and electricity theft. Existing boxes lack effective shock-proof and cushioning designs, allowing external forces to be directly transmitted to precision components, leading to equipment damage or inaccurate metering. Furthermore, key fasteners are often located in externally visible or easily accessible positions, allowing for easy disassembly by non-professionals, thus reducing the overall level of vandal protection. Second, regarding wiring management and electrical safety, conventional metering boxes typically employ an open wiring layout, resulting in a messy and exposed appearance. This not only affects heat dissipation and cleanliness but also poses safety hazards such as insulation damage, short circuits, detached labels, and unauthorized wiring or malicious cutting. Moreover, the internal cables lack fully enclosed physical isolation channels, necessitating improvements in electrical safety. Furthermore, regarding electricity privacy protection, the display screen of traditional electricity meters faces directly to the outside, allowing anyone near the viewing window to read the user's real-time electricity consumption data and historical electricity records. This public information display fails to meet the modern society's demand for confidentiality regarding personal habits, family routines, and other private data. In addition, existing devices generally lack intelligent proactive warning capabilities. When the box is struck, cut, or illegally opened, it cannot automatically detect the abnormality and issue audible and visual alarms, initiate video recording for evidence, or remotely notify management personnel; often, the damage is only discovered after actual losses have occurred. Finally, there is a conflict between the convenience and security of operation and maintenance. Some designs that overemphasize security (such as fully enclosed welding) make legitimate maintenance difficult; while designs that sacrifice security for convenience (such as easily pryable panels) fail to provide effective protection. Currently, there is a lack of an electricity metering box structure that can simultaneously provide high-strength physical protection, intelligent proactive warning, electricity privacy protection, and convenient and safe maintenance.

[0003] Therefore, it is necessary to develop an energy metering box with a security feature to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of current power metering boxes, such as weak protection capabilities and limited protection performance, the purpose of this invention is to provide a power metering box with multi-layered high-strength protection and a security structure.

[0005] The technical solution is as follows: An energy metering box with a security structure includes a wiring conduit, a fixing plate, a relay frame, a protection box, a sliding frame, a mounting frame, a positioning mechanism, a locking mechanism, a protection mechanism, a wiring mechanism, and a buffer mechanism. The wiring conduit is installed on the inner wall of the energy metering box or cabinet. A fixing plate is installed at the outlet hole of the wiring conduit. A relay frame is provided on the front side of the fixing plate. A protection box is provided on the front side of the relay frame. The protection box is an integrated anti-deformation steel structure with open front and rear. A sliding frame is slidably embedded in the protection box. A mounting frame for installing an energy meter is installed on the front side of the sliding frame. A positioning mechanism is provided on the front side of the mounting frame. A locking mechanism is provided on the rear side of the mounting frame. A protection mechanism is provided on the front side of the protection box. A wiring mechanism is provided in the middle of the front side of the relay frame. A buffer mechanism is provided between the wiring mechanism and the sliding frame. When the protection mechanism is locked, its front plane is completely inside the protection box. The buffer mechanism is used to provide elastic cushioning when the protection mechanism is subjected to a rearward violent impact.

[0006] Preferably, the positioning mechanism includes a positioning tube and a first elastic element. When the protection mechanism is inserted into the positioning tube and locked by the locking mechanism, the first elastic element is in a compressed state. When the locking mechanism is released, the first elastic element pushes the protection mechanism forward and pops it out.

[0007] Preferably, the locking mechanism includes a sliding pair, a guide rod, a locking block, and a double-slider electric slide rail. The double-slider electric slide rail drives the guide rod and the locking block to move away from or closer to each other, so that the locking block extends into or retracts from the positioning tube to lock or release the protection mechanism.

[0008] Preferably, the protection mechanism includes a protection plate, a positioning rod, and an indicator plate. The outer periphery of the protection plate is consistent with the inner periphery of the protection box. The positioning rod has a positioning groove, and the locking block locks the positioning rod by extending into the positioning groove.

[0009] Preferably, the wiring mechanism includes a wiring frame and a control chip module. The wiring frame covers the open structure with openings on the rear side of the protective box and shields the mounting fasteners of the relay frame. The control chip module is used to supply power and control the electronic control components.

[0010] Preferably, the buffer mechanism includes a second elastic element and a connecting plate. The second elastic element is located in the guide slide of the protective box and is used to elastically limit the movement of the sliding frame to the rear.

[0011] Preferably, it also includes a privacy component, which includes a terminal frame, an interconnect frame, an electrically controlled dimming glass, and a monitoring component. The electrically controlled dimming glass is used to display transparently when powered on and to display blurred when powered off, so as to selectively block the electricity consumption information of the electricity meter.

[0012] Preferably, the monitoring component includes a sensor group and an indicator group. The sensor group is used to monitor vibration and sound inside the protective box, and the indicator group is used to perform video recording, buzzer alarm, and indicator light indication when an abnormal state is detected.

[0013] The beneficial effects of this invention are: 1. This invention achieves extremely high physical protection and resistance to violent impacts. The protective box is integrally cast from an anti-deformation steel structure, which has high strength and can effectively resist violent damage such as smashing and squeezing. The key fasteners are blocked by the wiring rack or located in the innermost part of the protective box, making them impossible to operate directly from the outside, thus improving the anti-tampering performance. The innovatively designed buffer mechanism can cause the protective plate to drive the entire integrated device to compress the elastic element backward when subjected to a rearward violent impact, effectively absorbing and dissipating the impact energy and protecting the core metering device from direct damage.

[0014] 2. This invention integrates multiple intelligent security and proactive early warning functions. The built-in sensor group can sense the status inside the protection box in real time and intelligently determine whether it has been subjected to abnormal operations such as knocking or cutting. Once confirmed, the system immediately links the camera to automatically record video for evidence, the buzzer to sound a high-decibel alarm for deterrence, and the indicator light to flash warning. The alarm information can also be uploaded to the backend or management personnel terminal in real time through the network module, realizing a security closed loop from local defense to remote notification.

[0015] 3. This invention innovatively achieves privacy protection for electricity consumption information. An electronically controlled dimming glass is installed on the front side of the electricity meter, which has the characteristics of being transparent when powered on and blurring when powered off. In the unauthorized state, the glass presents an opaque, fogged state, and external personnel cannot see any data displayed on the electricity meter, effectively protecting the user's electricity consumption privacy. Only after authorization is obtained through QR code scanning and password verification does the glass become fully transparent, realizing a "transparent on demand" privacy protection mechanism.

[0016] 4. This invention achieves a balance between security and ease of maintenance. Through the cooperation of the locking mechanism and the positioning mechanism, the protective plate is firmly locked in the normal state and cannot be pulled open from the outside. After being authorized, authorized maintenance personnel only need to control the double slider electric slide rail to make the locking block retract. The first elastic element in the compressed state will automatically pop out the protective plate, which can be easily pulled out by maintenance personnel, making the front of the protective box completely open, realizing the efficient process of "one-click unlocking, automatic pop-out, and quick maintenance".

Detailed Implementation

[0036] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0037] Example 1, as Figures 1-18As shown, a power metering box with a security structure includes a wiring conduit 1, a fixing plate 2, a repeater frame 3, a protection box 4, a sliding frame 5, a mounting frame 6, a positioning mechanism 7, a locking mechanism 8, a protection mechanism 9, a wiring mechanism 10, and a buffer mechanism 11. The wiring conduit 1 is a steel square tube with several evenly spaced outlet holes on its front side. The wiring conduit 1 is used to install on the inner wall of the power metering box or cabinet 1002 and is used to lay the main line from the outside and other power supply branches. Fixing plates 2 are installed on the upper and lower sides of the wiring conduit 1 at the positions corresponding to the outlet holes. The front side of each fixing plate 2 has a threaded sleeve. A repeater is provided between the front sides of every two upper and lower fixing plates 2. The repeater frame 3 and the relay frame 3 are detachably installed on the fixing sleeve structure on the front side of the fixing plate 2 at the corresponding positions using fasteners. All repeater frames 3 are vertical frame structures, and each repeater frame 3 has a threaded sleeve on its front side. Each repeater frame 3 has a protective box 4 on its front side. The protective boxes 4 are all integrated box structures with open front and rear sides. The protective boxes 4 are integrally cast from anti-deformation steel structures. The front opening of the protective box 4 is open, and the rear opening is perforated. Each protective box 4 is detachably installed on the threaded sleeve on the front side of the repeater frame 3 at the corresponding position via fasteners on its rear inner wall. The middle of the left and right inner walls of each protective box 4 has a guide rail structure; the guide rail structure of the protective box 4 extends to the rear, protecting... Each guide rail structure of box 4 has a sliding frame 5 slidably embedded within it. Each sliding frame 5 has guide protrusions on its rear left and right sides. Each sliding frame 5 has a mounting bracket 6 installed on its front side. The mounting bracket 6 also has a frame structure, with mounting holes on its front left and right sides. These mounting holes are used to install the electricity meter 1001. Each mounting bracket 6 has a positioning mechanism 7 on its front side and a locking mechanism 8 on its rear side. A protection mechanism 9 is also provided on the front side of the protection box 4. The protection mechanism 9 closes the open front structure of the protection box 4. The positioning mechanism 7 and the locking mechanism 8 work together to position and lock the protection mechanism 9 within the protection box 4. The protection mechanism 9 observes the energy meter 1001 installed on the mounting frame 6. By controlling the locking mechanism to release the lock on the protection mechanism 9, the positioning mechanism 7 can pop out the protection mechanism 9. At this time, the protection mechanism 9 can be taken out from the front side of the protection box 4, so that the protection box 4 can be opened from the front side. The relay frame 3 has a wiring mechanism 10 in the middle of the front side. The wiring mechanism 10 is used to cover the open structure of the rear opening of the protection box 4. The wiring mechanism 10 is installed in the middle of the relay frame 3 by fasteners. The wiring mechanism 10 is used to connect the space between the wiring pipe 1 and the protection box 4, so that the wiring pipe 1 and the protection box 4 can be connected by the wiring mechanism 10. The wiring mechanism 10 is used to connect and organize the laid wiring harness, and controls the electrical connection of the wiring harness through the chip.A buffer mechanism 11 is provided between the wiring mechanism 10 and the sliding frame 5. The buffer mechanism 11 is used to elastically limit the rearward movement of the sliding frame 5, and a guide protrusion mechanism on the rear side of the sliding frame 5 is used to limit the buffer mechanism 11.

[0038] like Figures 13-18 As shown, the positioning mechanism 7 includes a positioning tube 71 and a first elastic element 72. Positioning tubes 71 are installed on both upper and lower sides of the front side of each mounting bracket 6. The protection mechanism 9 can extend and retract within the protection box 4 through the positioning tubes 71. A first elastic element 72 is installed near the positioning tube 71 on the front wall of each mounting bracket 6. The first elastic element 72 is a straight spring. When the protection mechanism 9 extends into the positioning tube 71 and is locked by the locking mechanism 8, the first elastic element 72 will enter a compressed state until the locking mechanism 8 is released. At this time, the first elastic element 72 will recover from the stressed state and push the protection mechanism 9 forward, causing the protection mechanism 9 to pop out from the front of the protection box 4.

[0039] like Figures 13-18 As shown, the locking mechanism 8 includes a sliding pair 81, a guide rod 82, a locking block 83, and a double-slider electric slide rail 84. A sliding pair 81 is installed between the left and right side walls of each mounting bracket 6. The sliding pairs 81 are all smooth optical shaft structures. Guide rods 82 are slidably connected to the left and right sides of the sliding pair 81. The guide rods 82 move left and right through the sliding pairs 81. The guide rods 82 are all vertically positioned. Locking blocks 83 are installed at the front positions of the upper and lower sides of the guide rods 82. The locking blocks 83 extend into adjacent positioning tubes 71 and are used to lock the protective mechanism 9. The left and right side walls of each mounting bracket 6... Double-slider electric slide rails 84 are installed at the middle position of each slide rail. The double-slider structure of the double-slider electric slide rail 84 is a counter-moving type driven by a screw. The double-slider structure of the double-slider electric slide rail 84 is connected to the guide rod 82 corresponding to the position. Controlling the operation of the double-slider electric slide rail 84 can cause the moving parts of the double-slider electric slide rail 84 to drive the guide rods 82 connected to move away from each other and closer to each other, thereby driving the locking block 83 away from or into the positioning tube 71. When the locking block 83 extends into the positioning tube 71, the locking block 83 locks the protection mechanism 9. The double-slider electric slide rail 84 is controlled by the wiring mechanism 10.

[0040] like Figures 13-15As shown, the protection mechanism 9 includes a protection plate 91, positioning rods 92, and an indicator plate 93. The protection plate 91 is fitted inside the front of the protection box 4. The outer contour of the protection plate 91 is consistent with the inner contour of the protection box 4. The protection plates 91 are all made of steel. The middle part of each protection plate 91 has a tempered glass observation window. Multiple positioning rods 92 are fixedly connected to the rear of each protection plate 91. The position of the positioning rods 92 is consistent with the position of the adjacent positioning tubes 71. The protection plate 91 extends into the positioning tubes 71 through the positioning rods 92 and moves back and forth in the protection box 4. Each positioning rod 92 has a positioning groove on the side facing the adjacent locking block 83. The locking block 83 locks the position of the positioning rod 92 by extending into the positioning groove. An indicator plate 93 is installed between the front sides of the positioning rods 92. The indicator plate 93 is used to affix the QR code controlling the operation of the corresponding wiring mechanism 10 and the number of the corresponding energy meter 1001. The affixed information of the indicator plate 93 can be viewed through the observation window structure of the protection plate 91.

[0041] like Figures 10-11 As shown, the cabling mechanism 10 includes a cabling frame 101 and a control chip module 102. Each repeater frame 3 has a cabling frame 101 located in the center of its front side. The cabling frame 101 covers the open structure of the rear side of the protection box 4. Each cabling frame 101 has a connecting box in the center of its rear side. The cabling frame 101 is installed in the center of the repeater frame 3 via its connecting box structure and fasteners. The cabling frame 101 and its connecting box are used to connect the space between the cabling conduit 1 and the protection box 4, allowing wire harnesses to be connected within the cabling conduit 1 and the protection box 4 via the frame and its connecting box. The front of the wiring rack 101 is used to connect and organize the laid wire harnesses. The wiring rack 101 has a structure with heat dissipation slots arranged in the front and back directions. A control chip module 102 is installed on the lower front side of the wiring rack 101. The control chip module 102 integrates chips such as control chip, Bluetooth control chip, relay and its control chip, and network transceiver module. The main line and branch line of the wiring conduit 1 are connected to the control chip module 102 to supply power and control the electrical control components of the power metering box with security structure.

[0042] like Figure 11 As shown, the buffer mechanism 11 includes a second elastic element 111 and a connecting plate 112. Multiple sets of second elastic elements 111 are provided between the wiring frame 101 and the sliding frame 5. The second elastic elements 111 are all straight springs. The second elastic elements 111 are located in the guide slide of the protective box 4. Each row of second elastic elements 111 has a connecting plate 112 installed at both ends. The front connecting plate 112 is fitted onto the positioning protrusion structure of the sliding frame 5, and the rear connecting plate 112 is installed on the left and right front sides of the wiring frame 101 by fasteners. The second elastic element 111 is used to elastically limit the movement of the sliding frame 5 to the rear.

[0043] like Figure 15As shown, it also includes a privacy component 12, which includes a terminal frame 121, an interconnect frame 122, an electrically controlled dimming glass 123, and a monitoring component 13. Each mounting bracket 6 has a privacy component 12 on its front side. The privacy component 12 is used to shield the display screen of the electricity meter 1001 installed on the mounting bracket 6 to protect the electricity usage privacy of the electricity meter 1001. Terminal frames 121 are installed on both the left and right sides of the mounting bracket 6. The terminal frames 121 are used for power supply and control. Multiple interconnect frames 122 are detachably installed on the front side of the terminal frames 121. The interconnect frames 122 are... The structure has power terminals on both the left and right sides of the rear. The interconnection frame 122 is connected to the terminal frame 121 through the power terminals. The middle of the interconnection frame 122 is equipped with an electrically controlled dimming glass 123. The electrically controlled dimming glass 123 is used to display transparently when the power is on and to display blurred when the power is off, so that the power consumption information of the energy meter 1001 can be selectively opened or blocked through the observation window structure of the protection board 91 and the electrically controlled dimming glass 123. The interconnection frame 122 at the top and bottom is equipped with a monitoring component 13. The monitoring component 13 is used to monitor the safety status of the protection box 4 and provide indication.

[0044] like Figure 15 As shown, the monitoring component 13 includes a sensor group 131 and an indicator group 132. The sensor group 131 is installed at the upper interconnect frame 122. The sensor group 131 is a combination of a vibration sensor and a sound decibel meter. The vibration sensor of the sensor group 131 is used to monitor the vibration inside the protective box 4, and the sound decibel meter of the sensor group 131 is used to monitor the sound decibel level and sound waveform inside the protective box 4. The indicator group 132 is installed at the lower interconnect frame 122. The indicator group 132 is a combination of a camera module, a buzzer module, and multiple indicator light modules. The camera module of the indicator group 132 is used to activate the camera when the sensor group 131 detects an abnormal state. The buzzer module of the indicator group 132 is used to sound an alarm when the sensor group 131 detects an abnormal state. The indicator light modules of the indicator group 132 are used to indicate when the sensor group 131 detects an abnormal state.

[0045] Example 2, as Figures 1-18As shown, the basic frame assembly of the power metering box with security structure is as follows: ① One or more wiring conduits 1 are horizontally installed on the inner wall of a power metering box or cabinet 1002 with a front door and lock, and multiple fixing plates 2 are installed on the inner wall of the cabinet 1002 according to the position of the outlet hole of the wiring conduit 1; the repeater frame 3 is installed at the fixing sleeve structure in front of the fixing plate 2 at the corresponding position by fasteners; ② The wiring frame 101 of the wiring mechanism 10 is installed on the front side of the repeater frame 3 by fasteners. At this time, the wiring frame 101 covers the fasteners connecting the repeater frame 3 and the fixing plate 2 to prevent the fasteners connecting the repeater frame 3 and the fixing plate 2 from being directly disassembled; ③ The main power supply line, branch line or network cable to be connected is connected from the wiring conduit 1. The relay frame 3 and the wiring frame 101 are respectively passed through the outlet hole positions, and the wire harnesses to be connected are arranged on the front side of the wiring frame 101, and the wire harnesses to be connected are connected to the control chip module 102. Then, the wire harnesses to be connected to the energy meter 1001 are pre-connected to one end from the control chip module. This step is called pre-wiring; ④ The rear connecting plate 112 of the buffer mechanism 11 is installed on the left and right positions on the front side of the wiring frame 101 with fasteners; ⑤ From this point on, the pre-wiring and basic frame assembly of the energy metering box with security structure are completed by the above "①-④" process; In addition, the fixing plate 2 at each outlet hole position in the cabinet 1002 is assembled into the basic frame as described in the above "①-④" process.

[0046] The protective box 4 of the power metering box with security structure is assembled as follows: ① The power meter 1001 is installed on the front side of the mounting bracket 6, and then the privacy component 12 and the detection component are connected to the terminal bracket 121 through the terminal structure of the interconnecting bracket 122, forming an integrated device consisting of the sliding bracket 5, the mounting bracket 6, the positioning mechanism 7, the locking mechanism 8, the privacy component 12, the detection component and the power meter 1001. Then, the circuit of the integrated device itself is connected, and the wire harness from the interconnecting bracket 122 and the control chip module 102 is pulled out and connected to the integrated device; ② The above process "①" is completed. The assembled integrated device is placed inside a protective box 4 via a sliding frame 5, with the sliding frame 5 positioned within the guide slide structure of the protective box 4. The sliding frame 5 is then pushed to position the integrated device at the front of the guide slide structure of the protective box 4. Next, the protective box 4 with the integrated device is connected to the front of a relay frame 3 whose basic frame assembly has been completed in the above-mentioned "assembly of the basic frame of the power metering box with security structure: ①-④" process. During this process, the wiring frame 101 is embedded into the open structure with openings on the rear side of the protective box 4. At this time, all wire harnesses are protected by the protective box 4 and the wiring frame. The wiring harness is enclosed by 101 and wiring conduit 1, preventing it from being exposed; the front connecting plate 112 of the buffer mechanism 11 is fitted onto the positioning protrusion of the sliding frame 5, at which time the buffer mechanism 11 exerts a forward elastic force on the integrated device through the second elastic element 111; then, a long-handled screwdriver can be inserted from the front of the protective box 4 and a fastener can be screwed in to fix the protective box 4 to the threaded sleeve of the relay frame 3. This fastener is located at the innermost part of the protective box 4 to prevent it from being directly disassembled; ④ The QR code and other information representing the energy meter 1001 are displayed. The QR code, affixed to the front of the indicator panel 93, is only used to access the password page of the control chip module 102 connected to the energy meter 1001. Control of the control chip module 102 is only permitted with the permission of the energy meter 1001 administrator and the user by entering the password. Afterwards, the QR code and other information can be scanned for verification, and the control chip module 102 can be accessed and controlled, such as for the operation and debugging of the electronically controlled dimming glass 123, the operation and debugging of the dual-slider electric slide rail 84, the debugging of Bluetooth, network and other functions, and the operation and debugging of the monitoring component 13.⑤ The protective mechanism 9 extends into the positioning tube 71 through its positioning rod 92, causing the protective plate 91 to extend into the protective box 4 until the positioning groove structure of the positioning tube 71 corresponds to the locking block 83. At this time, the first elastic element 72 is in a compressed state. At this time, the double slider electric slide rail 84 can be controlled to run through the above process "④", causing the double slider electric slide rail 84 to drive the guide rod 82 and the locking block 83 away from each other, so that the locking block 83 extends into the positioning groove of the positioning rod 92, thereby locking the protective mechanism 9 with the locking mechanism 8. After this process, the protective plate 91 is located in The front interior of the protective box 4, i.e., the front plane of the protective plate 91, is completely within the protective box 4, and the outer periphery of the protective plate 91 matches the inner periphery of the protective box 4. This reduces the operability of the protective plate 91 within the integrated protective box 4, avoiding prying or pulling it open, i.e., preventing the protective plate 91, as a moving part, from being pulled forward; ⑥ From this point on, the basic frame assembly of the aforementioned "basic frame assembly of the power metering box with security structure: ①-④" process has been completed through the above "①-⑤" process, and the assembly of all protective boxes 4 is now complete.

[0047] The overall security structure of the power metering box with security features is as follows: it consists of the aforementioned "basic frame assembly of the power metering box with security features" and "protective box 4 assembly of the power metering box with security features". After the assembly of the entire cabinet 1002 is completed, the left and right sides of the protective box 4 are in contact with each other inside the cabinet 1002, and the protective box 4 completely covers the wiring conduit 1. Thus, a layout is formed in which the power meter 1001 metering box is only facing the front of the cabinet 1002 through the protective plate 91, and the protective plate 91 can only be operated through QR code scanning and password verification. The indicator plate 93 is located behind the tempered glass observation window of the protective plate 91 and inside the protective box 4, which can prevent the information on the indicator plate 93 from being damaged or modified, thus avoiding security issues. The wiring rack 101 covers the repeater rack. The fasteners 3 and 2 that connect to the fixing plate 2 prevent direct disassembly of the fasteners connecting the repeater 3 and the fixing plate 2. The protection box 4 is fixedly mounted to the threaded sleeve of the repeater 3 by fasteners. These fasteners are located at the innermost part of the protection box 4, preventing direct disassembly. After the protection mechanism 9 is assembled and locked, the fasteners of the power metering box with the security structure are all located in positions that cannot be directly operated. All wiring harnesses of the power metering box with the security structure are enclosed by the protection box 4, the wiring rack 101 and the wiring conduit 1, which also prevents the wiring harnesses from being exposed. After the protection plate 91 is assembled, the protection plate 91 is located inside the front side of the protection box 4, which reduces the operability of the protection plate 91 in the integrated structure of the protection box 4 and avoids prying or pulling it open.

[0048] Examples of security measures for this power metering box with a security structure: ① Preventing direct external operation: Through the aforementioned "overall security structure of the power metering box with a security structure," the power metering box with a security structure cannot be directly operated, modified, have its wiring harness processed, or have its wiring rerouted by external parties; ② Preventing violent operations such as smashing, cutting, and sawing: Because the layout forms where only the power meter 1001 metering box faces the front of the cabinet 1002 from the protective plate 91, and after the cabinet 1002 is installed on the building wall, the parts that can be directly subjected to violent operations are the cabinet 1002 itself, the front side of the protective box 4, and the front side of the protective plate 91. While the cabinet 1002 itself has a certain structure to prevent violent operations in the existing technology, The current structure leaves all the electricity meters 1001 exposed after the cabinet door is opened, making them highly susceptible to violent operation. The protective box 4, however, is a one-piece cast steel structure designed to resist deformation, making its front less vulnerable to violent operation and damage. If the protective plate 91 is subjected to violent operation, as mentioned above, it cannot be operated in the forward direction. When subjected to violent operation, the protective plate 91 will only experience a direct or partial force to the rear. The protective plate 91, through its connected integrated device, will push the buffer mechanism 11 to the rear, compressing the second elastic element 111 when subjected to violent operation. This causes the protective plate 91 to move directly backward when subjected to a rearward force. The movement of the buffer mechanism 11 reduces the force exerted directly on the protective plate 91 by violent operations, thus buffering the force applied to the protective plate 91 and improving its safety. This includes, but is not limited to, violent operations such as smashing, cutting, and sawing. The buffer mechanism 11 reduces the force on the protective plate 91, preventing such violent operations from fully impacting it. Furthermore, after such violent operations, the integrated device consisting of the sliding frame 5, mounting frame 6, positioning mechanism 7, locking mechanism 8, privacy component 12, detection component, and energy meter 1001 will also be buffered by the buffer mechanism 11, ensuring the normal operation of power supply and energy metering, and reducing the impact of violent operations on the integrated device as a whole. Damage; ③ Alarm: When subjected to violent operations including but not limited to smashing, cutting, sawing, etc., the sensor group 131 of the monitoring component 13 will identify vibration information, sound decibel and sound waveform information. After identifying and analyzing the monitored information, it will determine whether it has been subjected to violent operations including but not limited to smashing, cutting, sawing, etc. If so, the camera module of the indicator group 132 will automatically start recording evidence when an abnormality is detected. The buzzer module will issue a high-decibel alarm to deter the source of violence. The indicator module will flash to warn surrounding personnel and external security systems. In addition, all monitoring data can be uploaded to the background, maintenance personnel terminal and other security systems via the network transceiver module of the control chip module 102.④ Electricity privacy protection: Through the electronically controlled dimming glass 123, after scanning the QR code on the indicator panel 93 to operate the control chip module 102, the electronically controlled dimming glass 123 becomes transparent when powered on and blurred when powered off. This allows the control chip module 102 to selectively open or close the electricity consumption information of the electricity meter 1001, thus protecting electricity privacy.

[0049] For the inspection and maintenance of the power metering box with security structure: The above-mentioned QR code scanning operation control chip module 102 controls the operation of the double slider electric slide rail 84, which drives the locking block 83 to exit the positioning tube 71. At this time, the first elastic element 72 in the compressed state is reset, and the positioning rod 92 is pushed forward, so that the protection plate 91 automatically pops out to the front of the protection box 4. At this time, the protection mechanism 9 can be easily pulled out to the front, exposing the inside of the protection box 4. Since the front opening of the protection box 4 is open, it is convenient to inspect and maintain the internal power meter 1001.

All equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention.
