Description

Technical Field

[0001] This invention relates to the field of metering box technology, and in particular to an integrated modular metering box for smart grids. Background Technology

[0002] As the terminal equipment for collecting and measuring electricity consumption information on the user side of the smart grid, the structural design of the metering box directly affects the grid operation and maintenance efficiency and electricity safety. Currently, the most common metering boxes on the market are mainly divided into two categories: traditional wired type and modular plug-in type.

[0003] In traditional wired metering boxes (such as the embedded metering box disclosed in Chinese Patent CN114137283A), the interior of the box is usually divided into a wiring area and an installation area. Each metering module is electrically connected to the input and output terminals by welding or screw crimping with wires. This structure has obvious drawbacks in practical applications: First, the wires inside the box are messy and not only occupy a lot of space, but also require disassembling and reassembling the wires one by one when maintaining or replacing the modules, which is cumbersome and can easily lead to electric shock accidents or phase-to-phase short circuits due to accidental contact; second, the traditional wiring method results in a complex electromagnetic environment inside the box, with prominent signal interference problems, affecting the metering accuracy.

[0004] To address the aforementioned issues, some existing technologies have proposed modular improvement solutions. For example, Chinese patent CN213517282U discloses a modular metering box that adopts a plug-in electrical connection structure, allowing metering modules to be quickly connected by inserting them into corresponding slots. However, this solution still has the following shortcomings: First, the positions of the slots and mounting rods are fixed during production and cannot be adjusted according to the actual thickness or quantity of the metering modules, resulting in poor adaptability of the box to modules of different specifications. Upgrading or replacing equipment on the power user side often requires replacing the entire box. Second, the wiring in this solution is still distributed near the plug-in area, posing a certain risk of electrical exposure when replacing modules. Third, existing modular metering boxes generally lack automated monitoring and access control functions; reading metering data still requires manual on-site opening and meter reading, which is not only inefficient but also makes it impossible to effectively trace acts of sabotage.

[0005] Furthermore, Chinese patent CN113109605A discloses a metering box with an inspection function, which has a sliding rail-type temperature monitoring device installed inside the box. However, the monitoring path of this device is limited to a fixed horizontal or vertical direction, which cannot achieve full-plane coverage, and there is no data interaction interface between the inspection mechanism and the metering module, so it cannot complete the remote automatic reading function.

[0006] In summary, existing metering boxes still have room for improvement in terms of module position adjustability, electrical connection safety, automated monitoring, and access control. Therefore, there is an urgent need to provide an integrated modular metering box for smart grids that features high integration, secure wiring, convenient module assembly and disassembly, and adjustable position.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Reference Figures 1-9 An integrated modular metering box for smart grids includes a box body 1. The box body 1 has a wiring groove 2 and an installation groove 3 inside. The wiring groove 2 is located in the middle of the box body 1. Two installation grooves 3 are located on either side of the wiring groove 2. Adjustment grooves 201 are provided on both side walls of the wiring groove 2. The adjustment grooves 201 pass through the wiring groove 2 and are connected to the adjacent installation grooves 3. Adjustment blocks 202 are inserted into the adjustment grooves 201. An installation rod 301 is fixedly installed on the side of the adjustment block 202 away from the wiring groove 2, extending into the installation groove 3. The box body 1 is fixed to a wall. Through slots are provided at the top and bottom of the wiring groove 2 to facilitate wire entry and exit. All wires are installed within the wiring groove 2. The adjustment blocks 202 can move and adjust the installation rods 301, allowing for adjustment within a certain range according to the number of metering modules 4.

[0025] The top and bottom of the adjusting block 202 are respectively provided with an inlet port 203 and an outlet port 204. An inlet connector 302 and an outlet connector 303 are fixedly installed on one side of the mounting rod 301. The inlet connector 302 and the outlet connector 303 are connected to the inlet port 203 and the outlet port 204 respectively via wires. A metering module 4 is provided on one side of the mounting rod 301. The metering module 4 has an inlet slot 401 and an outlet slot 402 on the side near the mounting rod 301. The inlet slot 401 and the outlet slot 402 are inserted into the inlet connector 302 and the outlet connector 303 respectively. The metering module 4 is connected through the inlet slot 401 and the outlet slot 402. The metering module 4 is inserted into the mounting rod 301 via the insertion slot 402 and the outlet slot 402. The inlet port 203 is used to connect to the external cable, and the outlet port 204 is used to connect to the incoming line. When the metering module 4 is inserted into the insertion slot 302 and the outlet port 303, the external current will enter through the insertion slot 302 and flow into the metering module 4 through the insertion slot 302 and the insertion slot 401. The metering module 4 then guides the current into the outlet port 204 through the outlet slot 402 and the outlet port 303 and connects it to the house through the incoming line. Therefore, the wires are all distributed in the wiring trough 2 and will not extend into the mounting groove 3, ensuring the safety when maintaining the metering module 4.

[0026] A spring rod 304 is inserted into the end of the mounting rod 301 away from the adjusting block 202. A pressure plate 305 is fixedly installed at the end of the spring rod 304 away from the mounting rod 301. The pressure plate 305 abuts against the inner wall of the mounting groove 3. When the mounting rod 301 moves to the designated position, the spring rod 304 is released, and the spring rod 304 will push the pressure plate 305 to abut against the inner wall of the mounting groove 3, thereby fixing the mounting rod 301 and the adjusting block 202.

[0027] A number of positioning teeth 306 are fixedly installed on the side of the pressure plate 305 away from the spring insert rod 304. Positioning tooth grooves 307 are opened on the inner wall of the mounting groove 3. The positioning teeth 306 are inserted into the corresponding positioning tooth grooves 307. When the pressure plate 305 abuts against the inner wall of the mounting groove 3, it will drive the positioning teeth 306 to be inserted into the corresponding positioning tooth grooves 307, which further improves the fixing effect of the mounting rod 301 and the adjusting block 202.

[0028] Limiting grooves 205 are provided at the top and bottom of the inner wall of the adjusting groove 201. Spring blocks 206 are inserted into the top and bottom of the adjusting block 202. The spring blocks 206 are inserted into the corresponding limiting grooves 205. A connecting rod 308 is fixedly installed at the end of the spring rod 304 away from the pressure plate 305. The connecting rod 308 is inserted into the mounting rod 301. A pressing rod 309 is horizontally fixedly installed at the end of the connecting rod 308 away from the spring rod 304. The two ends of the pressing rod 309 are in contact with the sides of the two spring blocks 206 that are close to each other. When the spring insert 304 is not released, the pressing rod 309 is in contact with the spring latch 206. At this time, the two spring latches 206 can extend and retract, which facilitates the installation of the adjusting block 202. When the adjusting block is installed in the designated position, releasing the spring insert 304 will drive the connecting rod 308 and the pressing rod 309 to move synchronously. After the pressing rod 309 moves, it will abut between the two spring latches 206. At this time, the two spring latches 206 are fixed after being abutted by the pressing rod 309, which further ensures the fixing effect of the adjusting block 202.

[0029] Two symmetrically arranged spring retainers 403 are inserted into the side of the metering module 4 near the mounting rod 301. The spring retainers 403 have a C-shaped structure and are installed in opposite directions. A fixing block 404 is fixedly installed on the side of the two spring retainers 403 that is close to each other. Fixing grooves 310 are opened on both sides of the mounting rod 301, and the 404 is inserted into the corresponding fixing grooves 310. The elastic force directions of the two spring retainers 403 are opposite to each other. Therefore, the two spring retainers 403 are close to each other and have a clamping effect. Together with the fixing block 404 and the fixing groove 310, they can fix the metering module 4.

[0030] The top of both sides of the cable tray 2 is provided with connecting slide rails 207. A movable frame 5 is provided above the cable tray 2. The bottom of the movable frame 5 is slidably connected to the two connecting slide rails 207 respectively. A horizontal slide groove 501 is provided on the top of the movable frame 5. A monitoring frame 502 is slidably installed in the horizontal slide groove 501. A monitoring probe 503 is fixedly installed at one end of the monitoring frame 502. The movable frame 5 moves back and forth on the connecting slide rails 207 by electric drive. The monitoring frame 502 moves back and forth in the horizontal slide groove 501 by electric drive. The movable frame 5 and the monitoring frame 502 can drive the monitoring probe 503 to move arbitrarily in the box 1 to monitor the temperature and the status of the metering module 4 in the box 1 and avoid safety hazards.

[0031] An electric telescopic rod 504 is fixedly installed on the monitoring frame 502. The telescopic end of the electric telescopic rod 504 passes through the monitoring frame 502 and is fixedly installed with a connector 505. A connector 405 is provided on one side of the metering module 4. The connector 505 is set to correspond with the connector 405. When it is necessary to remotely read the metering data in the metering module 4, the monitoring frame 502 is moved to the designated position, and the electric telescopic rod 504 is operated to push the connector 505 into the connector 405 to read and upload the data.

[0032] A cover plate 6 is hinged to the outside of the enclosure 1. An electronic lock is fixedly installed on the cover plate 6, and the cover plate 6 is locked to the enclosure 1 by the electronic lock. A display module and a card reader module are set on the outside of the cover plate 6. Both the display module and the card reader module are connected to the signal module 601 through wires. The signal module 601 is fixedly installed on the side of the cover plate 6 near the enclosure 1. A data module 506 is fixedly installed on the movable frame 5. The side of the data module 506 near the cover plate 6 is in contact with the signal module 601. The cover plate 6 is used to isolate and protect the metering module 4 and the wires inside the enclosure 1. When the cover plate 6 is locked to the enclosure 1, unauthorized personnel cannot open the cover plate 6. If the owner needs to view their own metering data, they can use the corresponding NFC card. When the card reader module receives a signal... Afterwards, the data is transmitted to the data module 506 via the signal module 601. The data module 506 operates the moving frame 5 and the monitoring frame 502 to move to the designated position and read the metering data in the designated metering module 4. The data is then transmitted to the display module via the signal module 601 for residents to view. When residents need to repair the metering module 4, they can open the cover 6 using the corresponding NFC card. Before the cover 6 is closed again, the corresponding NFC card will be locked to ensure that the metering module 4 in the box 1 can be locked to the corresponding personnel after being damaged by human intervention, thus preventing the metering box from being damaged by human intervention. When employees of the power company need to exceed the meter limit, they can read the data directly using the corresponding NFC card without opening the metering box, thus improving efficiency.

[0033] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
