Description

Technical Field

[0001] This application relates to the field of electricity metering box technology, and in particular to an integrated intelligent electricity metering box. Background Technology

[0002] Electricity metering boxes, as outdoor monitoring devices used at the end of the power system for centralized installation of electricity meters, data acquisition terminals, and low-voltage power distribution, are widely used in newly built residential communities, commercial areas, and urban renewal projects. Traditional electricity metering boxes are mostly made of metal or non-metal casings, and use a decentralized installation method with one meter per location, directly connected by wires.

[0003] The advantages of traditional solutions are simple structure and low cost. However, with the construction of smart grids and the increasing requirements of users for power supply reliability and ease of operation and maintenance, their shortcomings are becoming increasingly apparent. For example, they are bulky and occupy a lot of space. Moreover, the box size is usually large, which is not conducive to installation in corridors, electrical shafts or exterior walls with limited space, and affects the aesthetics.

[0004] Therefore, this application provides an integrated intelligent power metering box. Summary of the Invention

[0006] The purpose of this application is to solve at least one technical problem raised in the background art.

[0007] This application provides an integrated smart electricity metering box, including a metering box body, the metering box body including a box body and a T-shaped partition fixed to the inner wall of the box body, the T-shaped partition dividing the interior of the box body into a metering compartment, an outgoing switch compartment and a smart device compartment;

[0008] The metering chamber is equipped with several meters, the outlet switch chamber is equipped with an outlet switch, and the intelligent equipment chamber is equipped with a concentrator, a controller, an HPLC communication module and a miniature circuit breaker in sequence. The intelligent equipment chamber is also equipped with an independent power supply and a communication bus slot, supporting plug-and-play function expansion.

[0009] Preferably, the front of the housing is hinged with a metering door, which is made of transparent polycarbonate material.

[0010] By adopting the above technical solution, maintenance personnel can observe the operating status and readings of the meters without opening the door.

[0011] Preferably, each meter position corresponds to an independent modular terminal block, and all incoming and outgoing lines are connected through a unified busbar on the back.

[0012] By adopting the above technical solution, the purpose of front wiring and front display is achieved, which greatly simplifies the internal wiring. With this design, the overall width of the cabinet can be reduced and the depth can be optimized accordingly while supporting the same number of meters, thus achieving miniaturization.

[0013] Preferably, each of the meters is equipped with an independent live replacement interface.

[0014] By adopting the above technical solution, when replacing a single meter, there is no need to disconnect the main incoming line, which improves the safety and efficiency of operation and maintenance.

[0015] Preferably, the inner top and bottom of the enclosure are provided with labyrinth-style heat dissipation channels, the inner top wall and inner bottom wall of the enclosure are provided with strip-shaped heat dissipation vents communicating with the labyrinth-style heat dissipation channels, the outer surfaces of both sides of the bottom of the enclosure are provided with air inlet windows extending to the bottom labyrinth-style heat dissipation channels, the top of the enclosure is symmetrically provided with two cooling fans communicating with the top labyrinth-style heat dissipation channels, and the interior of the enclosure is provided with a temperature sensor, and the temperature sensor and the cooling fans are electrically connected to the controller.

[0016] By adopting the above technical solution, when the temperature inside the chamber reaches the threshold set by the controller, the temperature sensor transmits a signal to the controller, and the controller automatically controls the cooling fan to start, thereby achieving active heat dissipation and ensuring that the temperature inside the chamber remains constant.

[0017] Preferably, the back of the housing is provided with an installation mechanism, which includes an installation plate mounted on the wall, and installation holes are provided at the four corners of the installation plate.

[0018] By adopting the above technical solution, it is easy to fix the mounting plate to the wall using expansion bolts.

[0019] Preferably, a positioning plate is fixed on the surface of the mounting plate, and two symmetrical insertion slots are opened on the upper surface of the positioning plate. Two L-shaped insertion blocks corresponding to the two insertion slots are fixed on the back of the housing, and the L-shaped insertion blocks are inserted and fixed to the inner wall of the insertion slots.

[0020] By adopting the above technical solution, the metering box can be pre-positioned by inserting two L-shaped plug-in blocks into the plug-in slots on the positioning plate.

[0021] Preferably, the upper surface of the positioning plate has a rectangular opening, the inner wall of the rectangular opening is rotatably provided with a bidirectional threaded post, and one end of the bidirectional threaded post extends to the end of the positioning plate and is fixedly provided with an operating knob. The inner wall of the rectangular opening is slidably provided with two symmetrical sliding plates, and the surface of each sliding plate is provided with a threaded hole that is threaded to the outer surface of the bidirectional threaded post. The opposing surfaces of the two sliding plates are fixedly provided with locking posts. The inner wall of the rectangular opening has a through hole that extends into the insertion groove for the locking post to pass through. The surface of the L-shaped insertion block has a locking hole that matches the locking post, and the inner wall of the insertion groove has a locking groove that matches the locking post.

[0022] By adopting the above technical solution, rotating the operating knob drives the bidirectional threaded column to rotate. The rotation of the bidirectional threaded column drives the two slide plates to move to both sides simultaneously, thereby enabling the two locking pins to pass through the two through holes and the locking holes on the two L-shaped plug blocks respectively, and finally insert into the locking groove. This achieves the purpose of quickly locking the L-shaped plug blocks inserted into the plug groove, thereby achieving the purpose of quickly installing and positioning the metering box. At the same time, when the metering box needs to be replaced, it can be quickly removed from the wall.

[0023] Preferably, the surface of the mounting plate is provided with a tensioning assembly, which includes two tensioning frames symmetrically fixed to the back of the housing. The rear surface of the tensioning frame is provided with a T-shaped tensioning groove. The surface of the mounting plate is provided with a sealing cylinder corresponding to the tensioning frame. A piston disc is slidably provided on the inner wall of the sealing cylinder. A T-shaped tensioning block is fixed at the end of the piston disc. The T-shaped tensioning block is slidably connected to the inner wall of the T-shaped tensioning groove. A connecting pipe is provided between the two sealing cylinders, and the two ends of the connecting pipe extend into the interior of the two sealing cylinders respectively.

[0024] By adopting the above technical solution, the movement of the piston disc drives the movement of the T-shaped tensioning block, which in turn pulls the tensioning frame toward the mounting plate under the action of the T-shaped tensioning groove, thereby achieving the purpose of tensioning the metering box and effectively ensuring the stability of the metering box after installation.

[0025] Preferably, a rectangular box is fixedly provided on the surface of the mounting plate, a piston plate is slidably provided on the inner wall of the rectangular box, an L-shaped connecting rod is fixedly provided on the surface of the piston plate, the other end of the L-shaped connecting rod is fixedly connected to the surface of a sliding plate, an air pipe is provided on the surface of the rectangular box, one end of the air pipe extends into the interior of the rectangular box, and the other end of the air pipe extends into the interior of a sealing cylinder.

[0026] By adopting the above technical solution, when the L-shaped plug block and the plug slot are locked by rotating the operating knob, the movement of a slide plate can drive the piston plate to move through the L-shaped connecting rod. The movement of the piston plate can evacuate the inside of the two sealed cylinders through the air pipe.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The integrated intelligent electricity metering box described in this application significantly reduces the box size (width can be optimized to the 420mm level), making it easy to install in existing locations with limited space in old residential area renovations or in compact electrical shafts in new projects. This reduces the impact on building facades, lowers installation difficulty and cost, and improves construction and installation efficiency through modular design. The intelligent equipment compartment provides standardized physical and electrical interfaces for the intelligent upgrading of distribution areas, facilitating rapid deployment of advanced applications, meeting future needs for source-grid-load-storage interaction, and avoiding repeated modifications. Furthermore, the transparent design of the metering compartment door, modular plug-and-play replacement, and support for live-line work greatly improve the convenience of operation and maintenance inspections and the safety of operation, reducing power outage time and labor costs, and lowering the total life-cycle operation and maintenance costs of the equipment.

[0029] 2. The integrated intelligent electricity metering box described in this application, through the setting of an installation mechanism, allows the metering box to be pre-installed on the wall by bolts during installation. Then, the box body is inserted into the insertion slots on the positioning plate of the installation plate through two L-shaped plug-in blocks to achieve pre-positioning of the box body. Then, rotating the operating knob drives the bidirectional threaded column to rotate. The rotation of the bidirectional threaded column drives the two sliding plates to move to both sides at the same time, thereby driving the two locking pins to pass through the two through holes and the locking holes on the two L-shaped plug-in blocks respectively, and finally inserting them into the locking slots to achieve the purpose of quickly locking the L-shaped plug-in blocks inserted into the insertion slots. This achieves the purpose of quick installation and positioning of the metering box, and at the same time, it can be quickly removed from the wall when the metering box needs to be replaced.

[0030] 3. The integrated intelligent electricity metering box described in this application, by setting a tensioning component, when the metering box is pre-positioned, the tensioning frame moves downward with the box body, so that the T-shaped tensioning block enters the T-shaped tensioning groove below the tensioning frame. When the L-shaped plug-in block is locked to the plug-in groove by rotating the operating knob, the movement of a sliding plate can drive the piston plate to move through the L-shaped connecting rod. The movement of the piston plate evacuates the inside of the two sealing cylinders through the air pipe, thereby causing the piston disc to move. The movement of the piston disc drives the T-shaped tensioning block to move, so that the T-shaped tensioning block pulls the tensioning frame toward the mounting plate under the action of the T-shaped tensioning groove, thereby achieving the purpose of tensioning the metering box and effectively ensuring the stability of the metering box after installation.

[0045] The following is in conjunction with the appendix Figure 1 To be continued Figure 10This application will be described in further detail below.

[0046] Example 1

[0047] Please refer to the following carefully. Figure 1 , Figure 2 , Figure 3 An integrated intelligent power metering box includes a metering box body 100, which includes a box body 101 and a T-shaped partition 102 fixed to the inner wall of the box body 101. The T-shaped partition 102 divides the interior of the box body 101 into a metering compartment 103, an outgoing switch compartment 104, and an intelligent equipment compartment 105. The metering compartment 103 is equipped with several meters 106 via plug-in guide rail mounting seats. The outgoing switch compartment 104 is equipped with an outgoing switch 107 via plug-in guide rail mounting seats. The intelligent equipment compartment 105 is equipped with a concentrator 108, a controller 109, an HPLC communication module 1010, and a miniature circuit breaker 1011 in sequence via plug-in guide rail mounting seats. The intelligent equipment compartment 105 is also equipped with an independent power supply and a communication bus slot. This invention supports plug-and-play function expansion, which is convenient for future upgrades to intelligent distribution areas with advanced functions such as load identification, fault alarm, and remote opening and closing.

[0048] Please refer to this carefully. Figure 2 , Figure 3 The front of the container 101 is hinged with a metering door 1012, which is made of transparent polycarbonate material.

[0049] Specifically, it allows maintenance personnel to observe the operating status and readings of meter 106 without opening the door.

[0050] Please refer to this carefully. Figure 2 , Figure 3 Each meter has 106 positions corresponding to an independent modular terminal block, and all incoming and outgoing lines are connected through a unified busbar on the back.

[0051] Specifically, by achieving front wiring and front display, the internal wiring is greatly simplified. Through this design, the overall width of the cabinet 101 can be reduced while supporting the same number of meters, for example, from the traditional 600mm to 420mm. The depth can also be optimized accordingly to achieve miniaturization.

[0052] Please refer to this carefully. Figure 2 , Figure 3 Each meter 106 is equipped with an independent lead seal mechanism and a live replacement interface.

[0053] Specifically, when replacing a single meter, there is no need to disconnect the main power line, which improves the safety and efficiency of operation and maintenance.

[0054] Please refer to this carefully. Figure 2 , Figure 3 The top and bottom of the enclosure 101 are provided with labyrinth-style heat dissipation channels. The top and bottom walls of the enclosure 101 are provided with strip-shaped heat dissipation vents 1013 that communicate with the labyrinth-style heat dissipation channels. The outer surfaces of both sides of the bottom of the enclosure 101 are provided with air inlets that extend to the bottom labyrinth-style heat dissipation channels. The top of the enclosure 101 is symmetrically provided with two cooling fans 1014 that communicate with the top labyrinth-style heat dissipation channels. A temperature sensor is provided inside the enclosure 101. The temperature sensor and the cooling fans 1014 are electrically connected to the controller 109.

[0055] Specifically, when the temperature inside the enclosure 101 reaches the threshold set in advance by the controller 109, the temperature sensor transmits a signal to the controller 109, and the controller 109 automatically controls the cooling fan 1014 to start, thereby achieving active heat dissipation and ensuring that the temperature inside the enclosure 101 remains constant.

[0056] In this embodiment, the volume of the enclosure 101 is significantly reduced, and its width can be optimized to the 420mm level. This allows for easy installation in existing locations with limited space in old residential area renovations or in compact electrical shafts in new projects, minimizing the impact on building facades and reducing installation difficulty and cost. Secondly, the modular design improves construction and installation efficiency. The intelligent equipment compartment 105 provides standardized physical and electrical interfaces for the intelligent upgrade of the distribution area, facilitating the rapid deployment of advanced applications and meeting future needs for source-grid-load-storage interaction, avoiding repeated modifications. Furthermore, the transparent design, modular plug-and-play replacement, and live-line work support of the metering compartment 1012 greatly improve the convenience of operation and maintenance inspections and the safety of operation, reducing power outage time and labor costs, and lowering the total life-cycle operation and maintenance costs of the equipment.

[0057] Example 2

[0058] Based on Example 1, referring to Figures 4 to 10 And unlike Example 1, the following is true:

[0059] Please refer to this carefully. Figure 4 , Figure 5 The back of the housing 101 is provided with an installation mechanism 200, which includes an installation plate 201 installed on the wall, and installation holes are provided at the four corners of the installation plate 201.

[0060] Specifically, it facilitates fixing the mounting plate 201 to the wall using expansion bolts.

[0061] Please refer to this carefully. Figure 5 , Figure 6A positioning plate 202 is fixedly provided on the surface of the mounting plate 201. Two symmetrical insertion slots 203 are opened on the upper surface of the positioning plate 202. Two L-shaped insertion blocks 204 corresponding to the two insertion slots 203 are fixedly provided on the back of the housing 101. The L-shaped insertion blocks 204 are inserted and fixed to the inner wall of the insertion slots 203.

[0062] Specifically, the metering box can be pre-positioned by inserting two L-shaped plug-in blocks 204 into the plug-in slots 203 on the positioning plate 202.

[0063] Please refer to this carefully. Figure 6 , Figure 7 The upper surface of the positioning plate 202 has a rectangular opening. The inner wall of the rectangular opening is rotatably provided with a bidirectional threaded post 205. One end of the bidirectional threaded post 205 extends to the end of the positioning plate 202 and is fixedly provided with an operating knob 206. The inner wall of the rectangular opening is slidably provided with two symmetrical sliding plates 207. The surface of each sliding plate 207 is provided with a threaded hole that is threaded to the outer surface of the bidirectional threaded post 205. The opposing surfaces of the two sliding plates 207 are fixedly provided with locking posts 208. The inner wall of the rectangular opening has a through hole that extends into the insertion groove 203 for the locking posts 208 to pass through. The surface of the L-shaped insertion block 204 is provided with a locking hole 209 that is adapted to the locking posts 208. The inner wall of the insertion groove 203 is provided with a locking groove that is adapted to the locking posts 208.

[0064] Specifically, rotating the operating knob 206 causes the bidirectional threaded post 205 to rotate. The rotation of the bidirectional threaded post 205 causes the two sliding plates 207 to move to both sides simultaneously, thereby enabling the two locking posts 208 to pass through the two through holes and the locking holes 209 on the two L-shaped plug-in blocks 204 respectively, and finally insert into the locking groove. This achieves the purpose of quickly locking the L-shaped plug-in block 204 inserted in the plug-in groove 203, thereby achieving the purpose of quickly installing and positioning the metering box. At the same time, when the metering box needs to be replaced, it can be quickly removed from the wall.

[0065] In this invention, by setting up an installation mechanism 200, the metering box can be pre-installed on the wall by bolts using the mounting plate 201. Then, the box body 101 is inserted into the insertion slots 203 on the positioning plate 202 of the mounting plate 201 through two L-shaped plug-in blocks 204 to achieve pre-positioning of the box body 101. Then, rotating the operating knob 206 drives the bidirectional threaded column 205 to rotate. The rotation of the bidirectional threaded column 205 drives the two sliding plates 207 to move to both sides at the same time, thereby driving the two locking columns 208 to pass through the two through holes and the locking holes 209 on the two L-shaped plug-in blocks 204 respectively, and finally insert into the locking slots to achieve the purpose of quickly locking the L-shaped plug-in blocks 204 inserted in the insertion slots 203. This achieves the purpose of quick installation and positioning of the metering box, and at the same time, it can be quickly removed from the wall when the metering box needs to be replaced.

[0066] Please refer to this carefully. Figure 9 , Figure 10 The mounting plate 201 is provided with a tensioning assembly 300. The tensioning assembly 300 includes two tensioning frames 301 symmetrically fixed on the back of the housing 101. A T-shaped tensioning groove is opened on the rear surface of the tensioning frame 301. A sealing cylinder 302 corresponding to the tensioning frame 301 is fixed on the surface of the mounting plate 201. A piston disc 303 is slidably provided on the inner wall of the sealing cylinder 302. A T-shaped tensioning block 304 is fixed at the end of the piston disc 303. The T-shaped tensioning block 304 is slidably connected to the inner wall of the T-shaped tensioning groove. A connecting pipe 305 is provided between the two sealing cylinders 302. The two ends of the connecting pipe 305 extend into the interior of the two sealing cylinders 302 respectively.

[0067] Specifically, the movement of the piston disc 303 drives the T-shaped tensioning block 304 to move, so that the T-shaped tensioning block 304 pulls the tensioning frame 301 toward the mounting plate 201 under the action of the T-shaped tensioning groove, thereby achieving the purpose of tensioning the metering box and effectively ensuring the stability of the metering box after installation.

[0068] Please refer to this carefully. Figure 8 , Figure 9 A rectangular box 306 is fixedly mounted on the surface of the mounting plate 201. A piston plate 307 is slidably mounted on the inner wall of the rectangular box 306. An L-shaped connecting rod 308 is fixedly mounted on the surface of the piston plate 307. The other end of the L-shaped connecting rod 308 is fixedly connected to the surface of a sliding plate 207. An air pipe 309 is provided on the surface of the rectangular box 306. One end of the air pipe 309 extends into the interior of the rectangular box 306, and the other end of the air pipe 309 extends into the interior of a sealing cylinder 302.

[0069] Specifically, when the L-shaped plug block 204 and the plug slot 203 are locked by rotating the operating knob 206, the movement of a slide plate 207 can drive the piston plate 307 to move through the L-shaped connecting rod 308. The movement of the piston plate 307 evacuates the interior of the two sealing cylinders 302 through the air pipe 309.

[0070] In this invention, by setting a tensioning component 300, when the metering box is pre-positioned, the tensioning frame 301 moves downward with the box body 101, so that the T-shaped tensioning block 304 enters the T-shaped tensioning groove below the tensioning frame 301. When the L-shaped plug-in block 204 is locked to the plug-in groove 203 by rotating the operating knob 206, the movement of a sliding plate 207 can drive the piston plate 307 to move through the L-shaped connecting rod 308. The movement of the piston plate 307 evacuates the inside of the two sealing cylinders 302 through the air pipe 309, thereby causing the piston disc 303 to move. The movement of the piston disc 303 drives the T-shaped tensioning block 304 to move, so that the T-shaped tensioning block 304 pulls the tensioning frame 301 toward the mounting plate 201 under the action of the T-shaped tensioning groove, thereby achieving the purpose of tensioning the metering box and effectively ensuring the stability of the metering box after installation.
