Description

Technical Field

[0001] This utility model relates to the field of easy-to-maintain electricity meter technology, and more specifically, to a modular easy-to-maintain electricity meter. Background Technology

[0002] Currently, traditional electricity meters have numerous shortcomings in their structural design within the field of electricity metering. They often employ a monolithic, molded structure with tightly integrated functional components. This necessitates a complete disassembly and inspection of the entire meter when a malfunction occurs, making installation and disassembly cumbersome. For example, if the communication function is abnormal, the communication-related lines, chips, and peripheral circuits within the meter must be tested one by one, a time-consuming and labor-intensive process that severely impacts maintenance efficiency. Furthermore, with the advancement of smart grid construction and the diversification of user demands for electricity meter functions, such as remote monitoring and real-time data analysis, traditional electricity meters cannot be easily upgraded through simple modifications. Their fixed internal layout and circuit design prevent flexible addition or removal of modules to adapt to new functional requirements, making it difficult to meet user needs in complex application scenarios. Therefore, a new type of electricity meter is urgently needed to address these issues. Utility Model Content

[0016] Flexible Functional Expansion: When the power system has new functional requirements, such as adding support for new communication protocols or upgrading metering accuracy standards, only the corresponding communication module or metering module needs to be replaced. For example, to achieve higher-speed data transmission, simply replacing the communication module with one equipped with a higher-performance communication chip can easily meet the requirements without redesigning and manufacturing the entire electricity meter, providing power companies and users with great flexibility in functional upgrades.

[0017] Effective cost control: On the one hand, modular production makes the electricity meter manufacturing process more standardized and large-scale, reducing production costs. Different modules can be produced simultaneously on different production lines, improving production efficiency. On the other hand, during the maintenance phase, only the faulty module needs to be replaced, avoiding the replacement of the entire electricity meter and reducing equipment procurement costs. Moreover, efficient maintenance reduces power outage time, minimizing economic losses for users and businesses caused by power outages. From a life-cycle perspective, effective cost control is achieved. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figures 1-3 This utility model provides a technical solution: a modular and easy-to-maintain energy meter, including a support base 110, a metering module 120, a communication module 130, a display module 140, and a connecting component. A protective cover 111 is hinged to one side of the support base 110, and an observation window 114 is provided on one side of the protective cover 111. A connecting base 112 is fixedly installed on one side of the support base 110. The top of the connecting base 112 is provided with multiple mounting slots. The metering module 120, the communication module 130, and the display module 140 are all slidably installed in the corresponding mounting slots.

The first connecting part and the second connecting part are plugged in and electrically connected. The first connecting part is a metal pin 115, and the second connecting part is a metal socket that mates with the metal pin 115.

[0026] In some specific implementation schemes, the side walls of the metering module 120, communication module 130, and display module 140 are all provided with limiting protrusions 113, and the inner wall of the mounting groove is provided with limiting grooves that cooperate with the limiting protrusions 113. The limiting protrusions 113 and the inner wall of the limiting grooves are slidably connected. This can effectively and precisely guide the sliding of each module in the mounting groove, ensuring that each module is accurately installed in place, avoiding misalignment during installation, ensuring accurate insertion of the first connecting part and the second connecting part of the connecting components, thereby ensuring a stable electrical connection between the modules of the electricity meter and improving the reliability of the electricity meter's operation.

[0027] In some specific implementations, side plates are symmetrically arranged on both sides of the support base 110 and both sides of the protective cover 111, with the two side plates on each side being fixedly connected by bolts. This structural design enhances the overall structural stability of the energy meter. When the protective cover 111 is closed, the fixed connection of the side plates prevents the protective cover 111 from being accidentally opened, providing better protection for the internal metering module 120, communication module 130, and display module 140, reducing the impact of external factors on the modules, and extending the service life of the energy meter.

[0028] In some specific implementations, the metering module 120 includes a metering circuit board and a metering chip mounted on the metering circuit board. The edge of the metering circuit board has a first pin connected to the second connection portion. The metering circuit board also integrates a signal conditioning circuit, which is electrically connected to the metering chip and is used for filtering, amplifying, and other preprocessing of the acquired voltage and current signals. Furthermore, the metering circuit board has a calibration interface connected to the metering chip, facilitating accurate calibration of the metering module 120 by external calibration equipment. The communication module 130 includes a communication circuit board and a communication chip mounted on the communication circuit board. The edge of the communication circuit board has a second pin connected to the second connection portion. The communication circuit board also carries a power management circuit for... The communication circuit board provides a stable operating voltage for the communication chip and related communication circuits. It also features an antenna interface connected to the communication chip, allowing for compatibility with different types of external antennas to enhance the reception and transmission capabilities of communication signals and meet the needs of various communication environments. The display module 140 includes a display screen and a driver circuit board connected to it. The edge of the driver circuit board has a third pin connected to the second connection part. The driver circuit board integrates a storage chip for storing display data cache and display interface configuration information. Additionally, the driver circuit board includes a brightness adjustment circuit connected to the display screen, which automatically adjusts the brightness of the display screen based on the ambient light intensity collected by the ambient light sensor, improving the user's data viewing experience.

[0029] Please see Figure 4 Multiple sets of elastic telescopic rods are fixedly installed on one side of the support base 110. Each set of elastic telescopic rods has two members and a limiting strip 150 is fixedly installed at the telescopic end. The bottom end of the limiting strip 150 is slidably connected to the top end of the connecting base 112. When the limiting strip 150 is not subjected to external force, the limiting strip 150 is positioned directly above the limiting groove, and the bottom end of the limiting strip 150 is slidably connected to the top end of the limiting protrusion 113.

[0030] In some specific implementations, the elastic telescopic rod consists of a sleeve rod 151, a pull rod 152, and a spring 153. Multiple sleeve rods 151 are fixedly installed on one side of the support base 110. One end of each sleeve rod 151 is slidably connected to a pull rod 152. A spring 153 is fixedly installed between the pull rod 152 and the inner wall of the sleeve rod 151. When the module needs to be installed or removed, pressing the limiting strip 150 compresses the spring 153, allowing the limiting strip 150 to move inward, facilitating module insertion and removal. Releasing the spring 153 causes it to spring back, resetting the limiting strip 150 to limit the module's movement. This design is convenient and highly practical.

[0031] Working principle: Pressing the limiting strip 150 compresses the spring 153, allowing the limiting strip 150 to move inward and offset from the limiting groove. The metering module 120, communication module 130, and display module 140 are respectively inserted into the mounting slots on the connector 112. The limiting protrusion 113 on the side wall of the module slides along the limiting groove on the inner wall of the mounting slot, precisely guiding the module to the installation position. After installation, the metal pin 115 (first connecting part) at the bottom of the inner wall of the mounting slot is inserted into the metal socket (second connecting part) at the bottom of the module, achieving a stable electrical connection between the modules.
