[0019] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.
[0020] like Figures 1 to 13As shown, a multifunctional electricity metering box includes: a box body 1, a door 2 fixedly installed on the front of the box body 1, a front layer 3 and a middle layer 5 arranged inside the box body 1, the side of the middle layer 5 connected to a T-shaped plate 4, T-shaped plates 4 arranged at the bottom and top of the front layer 3, an indicator light 6 arranged on the outer side of the T-shaped plate 4 and located on the outer side of the front layer 3, a lock cylinder 7 arranged on the outer side of the door 2, and bolts 8 and screws 9 arranged on one side of the front layer 3. It also includes: An integrated partition section is located inside the enclosure 1 and is used to realize the modular integrated connection and partitioned arrangement of various electrical components inside the enclosure; The integrated partition includes an integrated component and a partition component. The integrated component is disposed on one side of the middle layer 5 and is connected to the partition component. The partition component is disposed on the top of the front layer 3. A moisture-proof section is located between the middle layer 5 and the inner top wall of the box 1, and is used to waterproof and moisture-proof the box 1. The moisture-proof part includes an air outlet and a filter. The air outlet is disposed on the inner wall of the housing 1, and the air outlet is connected to the filter. The filter is disposed on the outside of the air outlet. The auxiliary unit, located inside the enclosure 1, provides functions such as quick installation, anti-theft, and cable management. The auxiliary part includes a quick-connect socket, an anti-pry device, and a cable concealing component. The quick-connect socket is located below the integrated component, the anti-pry device is located on one side of the T-shaped plate 4, and the cable concealing component is located inside the T-shaped plate 4 for storing the cable.
[0021] Specifically, the enclosure 1 is equipped with a power distribution and control unit, a disconnect switch, a circuit breaker, an intelligent control module, and a status monitoring sensor; the indicator light 6 is connected to the status monitoring sensor and is used to illuminate the light display; the front layer 3 and the middle layer 5 divide the interior of the enclosure 1 into three parts: the front area, the core area, and the rear area; vertical plates are fixed to both sides of the T-shaped plate 4, and the vertical plates have recessed grooves for installing items; recessed grooves that fit the T-shaped plate 4 are opened at the center line positions of the front layer 3 and the middle layer 5; In practical applications, the T-shaped plate 4 is first inserted above and below the front layer 3 and the middle layer 5. Then, the T-shaped plate 4 is installed inside the box 1 to form a frame. After that, the indicator light 6, metering transformer 20, circuit breaker, etc. are installed on both sides of the T-shaped plate 4 as needed. The core meter 22 is fixed between the middle layer 5 and the T-shaped plate 4 with bolts 8 and screws 9 to prevent it from falling off. Then, the wires arranged on the outside of the box 1 are connected to the external line busbar 35. The external line busbar 35 completes the unified wiring platform. After turning on the circuit, the connected integrated busbar 15 is energized, and each wire is inserted into the integrated busbar 15 and the short metal piece 16 in sequence to reduce the messy structure and wiring, so that the power metering box can be used safely.
[0022] like Figures 1 to 6 As shown, the integrated component includes: Integrated busbar 15 is installed on the back panel of enclosure 1; Multiple pin heads 17 are provided on one side of the integrated busbar 15; A short metal piece 16 is disposed on one side of the integrated busbar 15, with one end penetrating the front layer 3 and the middle layer 5; an insulating sleeve is fitted on the short metal piece 16 at the position where it penetrates the front layer 3 and the middle layer 5, and it is fixed to the plate body by a snap fastener. The partition component includes: The metering transformer 20 is located on one side of the T-shaped plate 4 and on the outside of the front layer 3; The core meter 22 is located on one side of the metering transformer 20 and between the bolt 8 and the screw 9; The safe door 301 is located on one side of the front layer 3 and is used to seal and open the internal space; Specifically, the integrated busbar 15 and the short metal strip 16 are provided with a number of sockets so that electrical appliances in the three areas can be quickly connected and used; the metering transformer 20 is used for numerical processing of electrical energy metering; one end of the short metal strip 16 is connected to the external line busbar 35; the plug head 17 facilitates the insertion of the metering transformer 20, the core meter 22, and the indicator light 6, and makes contact with the internal metal chip to trigger power and promote normal operation of the equipment; the safe door 301 has a flip-top design with an observation window, an internal sealing ring, and is linked with the lock of the door 2, which has the functions of anti-pry and anti-accidental opening, and is connected to the front layer 3 by a hinge.
[0023] In practical applications, the integrated busbar 15 is installed on the back panel of the rear layer of the enclosure 1. The short metal strip 16 extends through to the other two areas. The connecting wires are connected to the short metal strip 16. After the circuit is turned on, the indicator light 6, the metering transformer 20, and the core meter 22 on the T-shaped plate 4 gradually start to work, which facilitates normal operation and reduces the mess between the wires, prevents tangling, and ensures the cleanliness of the equipment.
[0024] like Figure 2 , Figure 4 , Figure 5 , Figures 7 to 10 As shown, the air outlet component includes: L-shaped single plate 10, one end is set on the inner top wall of the box 1, and the other end is set on the back plate of the box 1; Air outlet 11 is located on the outside of L-shaped single panel 10; Air duct 12 is installed at the bottom of air outlet 11; The deflector plate 13 is installed on the outside of the air duct 12; Filter plate 14 is installed on the inner wall of air duct 12.
[0025] The filter element includes: Independent duct 24 is installed on the inner wall of the air outlet 11; Nylon mesh 25 is installed inside the independent pipe 24; Slider 27 is positioned at the top of independent pipe 24; Pull rod 26, through which slider 27 is installed; The arc-shaped piece 28 is positioned above the slider 27; The cable concealment component is located inside the T-shaped plate 4 and is used to store the cable.
[0026] Specifically, the L-shaped single plate 10 divides the internal space of the housing 1, creating an independent ventilation effect and facilitating the installation of the air outlet 11. The bottom of the L-shaped single plate 10 is sloping to facilitate moisture drainage. The air duct 12 is designed to guide moisture to the outside of the housing 1 for drainage, preventing internal dampness. The guide plate 13 is conical in shape to facilitate outward diffusion of moisture. The nylon mesh 25 facilitates primary filtration of impurities, and the filter plate 14 facilitates secondary filtration of internal impurities, ensuring the cleanliness of the air duct 12, thereby extending its service life and reducing the probability of wear and tear. The slider 27 is connected to the pull rod 26, and the threads of the pull rod 26 and the slider 27 are compatible. The slider 27, in conjunction with the pull rod 26, facilitates the adjustment of the arc-shaped plate 28. Angle; the arc-shaped plate 28 allows for adjustment of the tilt angle, facilitating the closing or outflow of moisture; the independent pipe 24 has grooves, forming a multi-bend cavity design, where some moisture in the air condenses into water droplets at the bends and is discharged outside the box through one end of the pre-set air duct 12 inside the cavity. By setting up the multi-bend independent pipe 24, the air circulation path is extended, and when hot and humid external air enters, it can fully condense on the inner wall of the pipe. According to the principle of condensation, under the temperature difference between day and night, this structure can effectively reduce the humidity of the air entering the core area of the box 1; the bottom of the arc-shaped plate 28 has a shaft that is nested in the groove at the top of the slider 27; large dust particles will be blocked by gravity and airflow in the bend channel and cannot enter the air duct 12, achieving preliminary dust prevention and dehumidification; In practical applications, when waterproofing or moisture-proofing the interior of the housing 1 is required, firstly, external air enters the inner wall of the air outlet 11, and some moisture enters the independent pipe 24. After being bent internally, it condenses into water droplets. After being filtered by the nylon mesh 25, it flows out to one end due to gravity and enters the air duct 12. It is then filtered by the filter plate 14 and discharged to the outside to ensure the dryness of the interior of the housing 1. At the same time, another part of the moisture enters the outside of the air outlet 11 and flows along the outside of the guide plate 13, guiding the moisture to the outside and preventing the air duct 12 from coming into excessive contact with moisture and becoming damp. When adjusting the arc-shaped plate 28 to allow moisture to flow out from one side of the independent pipe 24, moisture or external air will blow against the arc-shaped plate 28. The arc-shaped plate 28 will move together with the linkage slider 27 along the outside or down of the pull rod 26. After moving, the arc-shaped plate 28 will form an outward convex shape to create an outward expansion trend, ensuring rapid diffusion of moisture, reducing the residue of moisture inside, and improving the internal moisture-proof performance of the box 1.
[0027] like Figure 5 , Figure 6 , Figure 11 , Figure 13 As shown, the wire-concealing component also includes: Slot 29 is provided on one side of T-shaped plate 4; Conduit 30 is installed inside slot 29; The external line busbar 35 is located on the outside of the enclosure 1 and is connected to the integrated busbar 15 via a short metal piece 16; The fast socket includes: The insulating base 18 is U-shaped and is set on the back plate of the housing 1. The insulating base 18 is pre-set with plug-in terminals that are connected to the integrated busbar 15. The bottom of the modular functional unit is provided with a male head, which can be quickly aligned and inserted into the female head terminal on the insulating base 18 and mechanically secured by the positioning plate 19. Positioning plate 19 is positioned above insulating base 18.
[0028] Specifically, the conduit 30 can retract the cable internally, making it easy to store the cable and avoid mess or tangling; the slot 29 facilitates the installation of the conduit 30; the external cable busbar 35 is a unified terminal block, making it easy to connect the circuit; the insulating base 18 has a module installed inside, which is a modular quick-connect base, and the insulating base 18 is pre-connected with busbars and signal terminals, and connects to the integrated busbar 15; the external cable busbar 35 serves as a unified access terminal for external cables, and is electrically connected to the integrated busbar 15 through the short metal piece 16, realizing the neat connection of internal and external lines; the integrated busbar 15 includes at least mutually insulated neutral and live wires, and the partitioning of the sockets on each busbar is explained; the short metal piece 16 is a conductor that connects the external cable busbar 35 and the integrated busbar 15 to a specific power source, and how insulation and mechanical fixation are ensured when it passes through the front layer 3 and the middle layer 5.
[0029] In practical applications, when it is necessary to store the wire, first pull out one end of the wire tube 30, then insert the wire into the wire tube 30, and after completing the wiring, put it back into the slot 29 to form a hidden situation. In each section at the front of the T-shaped plate 4, the corresponding insulating base 18 modular quick-connect base is installed. At the same time, the external line busbar 35 is uniformly installed on the side to connect the external wiring integrated busbar 15. At this point, all electrical connection components are in place and their positions are precisely fixed, eliminating the possibility of arbitrary wiring later.
[0030] like Figure 7 , Figure 8 , Figures 11 to 13 As shown, the anti-pry device includes: The metering lock 21 is set on one side of the T-shaped plate 4 and located outside the core meter 22; The busbar connector 23 is located outside the metering one-time lock 21; The first main rod 231 and the second main rod 232 are both installed on the inner wall of the metering one-time lock 21; The arc-shaped rack 233 is located on the outside of the first main rod 231; The ratchet 234 is meshed with the lower part of the arc-shaped rack 233; Anti-pry marking parts are installed on the inner wall of the cabinet door 2 to leave damage marks when the cabinet door is illegally opened.
[0031] Ink sac 32 is located on the outside of the central axis 31; Hinge 33 is located between the box body 1 and the box door 2; The central axis 31 is set through the hinge 33; Spring 34 is located on one side of ink sac 32.
[0032] Specifically, the metering one-time lock 21 is sleeved on the outside of the metering transformer 20 and fixed with a one-time screw to ensure that traces will be left after theft; the busbar connector 23 facilitates the connection of one of the circuits to ensure normal use of the equipment; the arc-shaped rack 233 and the ratchet 234 mesh with each other to ensure forward rotation; the ink sac 32 is filled with ink, which, together with the central shaft 31 and the spring 34, forms visible damage marks; the first main rod 231 and the second main rod 232 facilitate the support of the arc-shaped rack 233 and the ratchet 234; and one end of the first main rod 231 is provided with a slot that matches the one-time screw; In practical applications, when it is necessary to fix the core meter 22, the disposable screw is turned to lock it inside the metering disposable lock 21. It can only be turned in the forward direction and cannot be turned in the reverse direction. After turning the first main rod 231, the arc-shaped rack 233 meshes with the ratchet 234. It is a special lock that can only be tightened and cannot be loosened, forming a lock to prevent the staff from not being able to know the situation in time after theft. After the lock is tightened with a special tool, the only way to loosen it is to break a weak point on the cover, such as a small plastic piece. Once broken, it can be seen at a glance.
[0033] In addition, an ink sac 32 is installed inside the door 2. When the door is closed normally, a small pin holds the ink sac 32 but does not puncture it. If someone forcibly pries open the door, the pin will puncture the ink sac 32, and the marking liquid ink inside will stain the central axis 31 of a pre-set white rod, forming obvious signs of damage. It may also spray onto the door frame, making it obvious that someone has pried open the door.
[0034] Working principle: The T-shaped plate 4 serves as the core framework, and the pre-set slots on its two side vertical plates mate with the corresponding recessed slots on the front layer 3 and middle layer 5, forming a modular installation base. The metering transformer 20, core meter 22, indicator lights 6, and other equipment are fixed to the designated areas of the T-shaped plate 4 or shelves like standard components. The core meter 22 is reinforced with bolts 8 and screws 9. The safe door 301 provides sealed physical protection for critical areas on the front layer 3.
[0035] Workflow: During assembly, workers snap or lock each functional unit into or onto the corresponding position of the frame according to the preset plan. The process is standardized and requires no on-site processing, which fundamentally eliminates layout chaos. In the process of central power distribution hub, the integrated busbar 15 is fixed to the back plate of the enclosure 1, serving as the power distribution center of the entire enclosure 1. The short metal plate 16 serves as the power trunk line, starting from the integrated busbar 15, passing through the front layer 3 and the middle layer 5, and transmitting power to each zone.
[0036] During the standardization of access points, multiple sets of plug heads 17 are provided on one side of the integrated busbar 15 for connecting internal equipment leads. On the back panel of the enclosure 1 of each section, an insulating base 18 is provided, which has pre-connected plug terminals that are connected to the integrated busbar 15.
[0037] During the process of unifying the external interface, all external cables are first connected to the external cable busbar 35 located on the outside of the enclosure 1. The external cable busbar 35 is connected to the internal integrated busbar 15 through the short metal piece 16 to achieve a neat electrical connection. Electrical path logic: The complete current path is: external cable, external line busbar 35, short metal strip 16, integrated busbar 15, through the plug head 17 or the module male head inserted into the insulating base 18, the core electric meter 22 and metering transformer 20 of each functional unit. This path realizes a fully structured wiring, without messy flying wires, high safety and easy maintenance. The moisture-proof section is an "environmental regulator" inside the enclosure 1. It uses physical principles to achieve moisture prevention, and its working process is a continuous air handling process.
[0038] Air intake and primary condensation dehumidification: External air first enters through the air outlet 11, with a portion flowing into the independent duct 24 on the inner wall of the air outlet 11. This duct is designed with multiple bends; when the hot, humid air flows through these bends, it comes into contact with the relatively cooler duct wall, causing some moisture to condense and form water droplets that adhere to the duct wall, achieving initial dehumidification. The bends also cause large dust particles to deposit due to inertial impaction.
[0039] During the filtration and condensate discharge process, the pre-treated air, carrying smaller water droplets and dust, continues to flow, undergoing primary filtration through the nylon mesh 25 inside the independent duct 24. Subsequently, the air and condensate enter the lower air duct 12. Filter plates 14 are installed on the inner wall of the air duct 12 for secondary fine filtration. The condensed water droplets, under gravity, are guided along the inner wall of the air duct 12 to the outside of the housing 1 for discharge.
[0040] The airflow is guided and externally protected. Another portion of the air entering the independent duct 24 flows along the outside of the L-shaped single plate 10. One end of the L-shaped single plate 10 is fixed to the inner top wall of the housing 1, and the other end is fixed to the back plate, forming an isolation. The guide plate 13 on its outer side can diffuse and throw away any water droplets or condensate flowing down the plate, preventing them from dripping onto the electrical equipment below.
[0041] The ventilation adjustment mechanism allows the slider 27 to move at the top of the independent duct 24 by pulling or rotating the lever 26 that passes through it, thereby changing the tilt angle of the arc-shaped plate 28 connected above the slider 27. This structure functions as a damper, used to adjust the opening size of the air intake channel to adapt to different ambient humidity conditions.
[0042] The entire system operates passively, relying on the physical principles of temperature difference condensation, filtration and adsorption, gravity diversion and airflow guidance to continuously reduce the humidity and dust content of the air entering the core area of the enclosure 1, providing a dry and clean operating environment for the core electrical equipment; The modular functional unit has a male pin at the bottom. During installation, simply align it with the pre-installed insulating base 18 in the corresponding partition and insert it. Then, use the positioning plate 19 above to mechanically secure it. This will instantly complete the electrical and physical connection, achieving "plug and play" and greatly improving installation and maintenance efficiency. The tamper-evident lock features an internal mechanical anti-rollover mechanism. When an authorized person uses a special tool to turn the lock, it rotates the internal first main rod 231, causing the arc-shaped rack 233 on it to drive the ratchet 234 to rotate in one direction, thus tightening the lock. Because the engagement between the ratchet 234 and the arc-shaped rack 233 is unidirectional, the tool cannot disengage in the opposite direction. Any unauthorized disassembly attempt will result in damage to the lock housing, leaving clear evidence. The female connector 23 is used to connect this protective circuit. During the intrusion trace marking process, the device is integrated into the hinge 33 area of the cabinet door 2. When normally closed, a component on the cabinet door 2 gently presses down on the ink sac 32 while keeping it intact. The ink sac 32 is fitted onto the central shaft 31 that runs through the hinge 33, and is supported on one side by a spring 34. When the cabinet door 2 is illegally and forcibly pried open to an angle exceeding a set value, the relative displacement between the door and the cabinet body 1 intensifies, triggering a mechanism to puncture the ink sac 32. The colored liquid inside is rapidly released with the assistance of the spring 34, splashing onto the preset central shaft 31, the inner wall of the cabinet door 2, or the door frame, forming permanent marks that are not easily removed, providing direct evidence for subsequent investigations. A slot 29 is provided on the side of the T-shaped plate 4, into which a conduit 30 is embedded. Shorter connecting cables between devices can be neatly stored by threading them through the conduit 30, and the conduit 30 can be pushed back into the slot 29 for concealment. This ensures that there are no messy cables in sight when the cabinet door 2 is opened, which is both aesthetically pleasing and safe. In practical applications, the three systems work together: During the installation phase, the physical positioning and installation of all functional units are first completed using the skeleton. Then, an integrated connection network is established through the integrated partition sections. During operation, the equipment is powered on. The moisture-proof section works continuously, providing a dry and clean air environment for the operating electrical equipment through the path formed by components such as the air outlet 11, independent duct 24, nylon mesh 25, air duct 12, and filter plate 14. During the security protection phase, the metering one-time lock 21 always physically locks and protects the key equipment. Once an unauthorized prying of the box door 2 occurs, the anti-pry marking parts will be triggered immediately to leave evidence of intrusion.
[0043] In summary, through the precise design and collaborative working principle of the above three systems, this invention achieves multifunctional integration and a leap in performance of the electricity metering box in terms of structure, environmental adaptability, installation efficiency, and safety protection.
