Description

Technical Field

[0001] This application relates to the technical field of power measurement instruments, and in particular to a partitioned sealed power meter. Background Technology

[0002] In the power system, the electricity meter is the core device for measuring users' electricity consumption, and its performance directly affects the accuracy of electricity metering, the stability of power grid operation, and the safety of users' electricity use.

[0003] Traditional electricity meters have low modularity, with tightly connected functional modules and a lack of independent disassembly and assembly design. When a module malfunctions, maintenance personnel often need to disassemble the entire electricity meter or even replace the whole unit. This not only increases maintenance and time costs but may also lead to interruption of metering data, affecting the continuity of electricity metering. In recent years, although some electricity meters have introduced modular design concepts, there are still shortcomings in terms of structural optimization and sealing protection. Therefore, developing a new type of electricity meter that can achieve functional zoning, efficient sealing, and convenient maintenance has become an urgent task to meet the needs of modern electricity metering.

[0004] Regarding the aforementioned technologies, the applicant believes that there are deficiencies in the ability to quickly disassemble and maintain specific parts of the electricity meter. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a zoned sealed energy meter.

[0006] This application provides a zoned sealed energy meter, which adopts the following technical solution: A partitioned sealed energy meter includes a housing, a base plate, and a partition plate fixedly connected inside the housing. The housing is divided into an upper cavity and a lower cavity by the partition plate. A communication module is installed inside the upper cavity, and a quick-release device is provided between the communication module and the housing. A display and operation module is installed on the housing of the upper cavity and is slidably connected to the housing. A metering module is installed inside the lower cavity and is slidably connected to the housing. A wiring device is installed on the bottom housing of the lower cavity and is fixedly connected to the bottom of the housing. The housing is bolted to the base plate. The communication module, display and operation module, metering module, and wiring device are connected through a dedicated interface.

[0007] By adopting the above technical solution, the housing is divided into an upper cavity and a lower cavity by a partition plate, making different functional modules physically independent. The metering module, as the core metering component, is located in the lower cavity along with the wiring device, which reduces electromagnetic interference from high voltage to the communication module and display operation module in the upper cavity. The communication module and display operation module are concentrated in the upper cavity, which also avoids the impact of their own signals on metering accuracy and improves overall operational stability. The partitioned design allows for differentiated treatment according to the sealing requirements of different modules. The lower cavity involves wiring and high voltage, so a reinforced sealing structure is used to protect the metering module and wiring device from environmental corrosion. The upper display operation module needs to interact with the outside world, so basic sealing can be ensured while maintaining operational convenience, balancing function and protection. A quick-release device is provided between the communication module and the housing, and the display operation module and metering module are slidably connected to the housing, enabling partial disassembly and maintenance of the energy meter.

[0008] Preferably, the quick-release device includes a fixed base, a rotating base, a rotating handle, multiple sets of connecting rods, and multiple sets of hinges. The fixed base is fixedly connected to the housing, the rotating base is mounted on the fixed base, and the rotating base is rotatably connected to the fixed base. The multiple sets of connecting rods are evenly installed circumferentially on the fixed base and the rotating base. The two ends of each set of connecting rods are fixedly connected to the fixed base and the rotating base respectively through two sets of hinges. The rotating handle is fixedly connected to the rotating base.

[0009] By adopting the above technical solution, the rotating base can be rotated by rotating the handle, which can synchronously link multiple sets of connecting rods evenly distributed in the circumference. Utilizing the rotation characteristics of the hinge, the two ends of the connecting rods are connected to the fixed base and the rotating base respectively. When the rotating base rotates, the multiple sets of connecting rods can tighten or loosen at the same time. When the rotating base is locked, it applies a uniform clamping force to the communication module device, thereby realizing the rapid locking or unlocking of the communication module device.

[0010] Preferably, the display operation module includes a display screen, operation buttons, a mounting plate, and a magnetic strip. The display screen is fixedly connected to the mounting plate, the operation buttons are movably connected to the mounting plate below the display screen, a sliding device is provided between the housing and the display operation module, and the magnetic strip is fixedly connected to the bottom of the mounting plate.

[0011] By adopting the above technical solution, the display screen and operation buttons are fixed together on the mounting plate to form a unified interactive unit. Users can view data in the same area. The display operation module is connected to the housing through a sliding device. When the display operation module malfunctions, the entire module can be directly pulled out of the housing along the sliding trajectory without disassembling other parts of the housing or disconnecting complex circuits. The internal components can be detected by sliding the display operation module open.

[0012] Preferably, the sliding device includes two sets of guide rail devices, two sets of sliders, and a sealing assembly. The two sets of guide rail devices are bolted to the housings on both sides of the display operation module. The two sets of sliders are respectively mounted on the two sets of guide rail devices and are slidably connected to the guide rail devices. The display operation module is detachably connected to the sliders. The sealing assembly is fixedly connected to both the guide rail devices and the display operation module.

[0013] By adopting the above technical solution, multiple sets of guide rail devices are fixed to the housing with bolts. The slider is slidably connected to the guide rail and directly associated with the display operation module, forming a stable guiding structure. The sealing components are fixed to the guide rail devices and the display operation module respectively. When the module is pushed into the housing, the two sealing structures can fit tightly together to form double protection.

[0014] Preferably, the sealing assembly includes multiple sets of first sealing strips and magnetic sealing strips. The multiple sets of first sealing strips are respectively fixedly connected to the guide rail device, the housing on the upper part of the display operation module, and both sides of the display operation module. The magnetic sealing strip is fixedly connected to the housing at the bottom of the display operation module and is connected to the magnetic strip at the bottom of the connecting plate.

[0015] By adopting the above technical solution, the first sealing strip is installed at different connection points between the corresponding display operation module and the housing to prevent dust and moisture from entering the cavity along the guide rail, block the entry path of top contaminants, and avoid corner leakage. The magnetic sealing strip fixes the bottom of the display operation module relative to the housing, and uses the magnetic attraction property to connect with the magnetic strip to enhance the sealing pressure, fix the position of the display operation module, and strengthen the bottom protection.

[0016] Preferably, a moving device is provided between the metering module and the housing. The moving device includes multiple sets of cavity guide rails, multiple sets of module slides, a locking device, and multiple sets of second sealing strips. Two sets of cavity guide rails are installed on the housing on both sides of the metering module and are fixedly connected to the housing. Two sets of module slides are respectively installed on the two sets of cavity guide rails and are slidably connected to the cavity guide rails. The metering module is installed on the two sets of module slides. The locking device is installed at one end of the cavity guide rail. Multiple sets of second sealing strips are fixedly connected to the housing around the metering module and the multiple sets of cavity guide rails.

[0017] By adopting the above technical solution, two sets of cavity guide rails are fixed on both sides of the housing. The module slide slides along the guide rails and carries the metering module, forming a stable guiding structure. This ensures that the metering module is subjected to uniform force during the pulling process, preventing the internal components from loosening due to shaking. The locking device adopts a spring steel ball design. When the metering module is pushed into the cavity and reaches the working position, the spring steel ball will embed into the corresponding slot of the module slide or the metering module to achieve automatic locking. The second sealing strip is distributed on the housing and cavity guide rails around the metering module, forming multiple sealing barriers.

[0018] Preferably, one end of the metering module is provided with an electrical connection device, which includes a spring pin with a stroke of eight millimeters.

[0019] By adopting the above technical solution, when the metering module slides more than eight millimeters relative to the housing, the spring pin disengages from the docking interface due to exhaustion of its stroke, and the power supply to the metering module is automatically cut off, ensuring that the module is in a power-off state and avoiding the risk of electric shock or short circuit damage to the module caused by live operation.

[0020] Preferably, a third sealing strip is provided at the connection between the partition plate and the bottom plate, and at the connection between the housing and the bottom plate, and the third sealing strip is fixedly connected to the partition plate and the bottom plate respectively.

[0021] By adopting the above technical solution, the partition plate is the key structure for dividing the upper cavity and the lower cavity. The third sealing strip at the connection between the partition plate and the bottom plate can tightly fill the gap, preventing dust, water vapor and corrosive gas that may exist in the lower cavity from spreading to the upper cavity. At the same time, it prevents minor pollutants in the upper cavity from falling into the lower high-voltage area. The third sealing strip at the connection between the shell and the bottom plate can seal the gap between the bottom of the shell and the bottom plate, preventing external environmental objects from entering the inside of the electricity meter.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The housing is divided into an upper cavity and a lower cavity by a partition plate, making different functional modules physically independent. The metering module, as the core metering component, is located in the lower cavity along with the wiring device. This reduces electromagnetic interference from high voltage to the communication module and display / operation module in the upper cavity. The communication module and display / operation module are concentrated in the upper cavity, which also avoids the impact of their own signals on metering accuracy and improves overall operational stability. The partitioned design allows for differentiated treatment based on the sealing requirements of different modules. The lower cavity involves wiring and high voltage, so a reinforced sealing structure is used to protect the metering module and wiring device from environmental corrosion. The upper display / operation module needs to interact with the outside world, so basic sealing can be ensured while maintaining operational convenience, balancing functionality and protection.

[0023] 2. Two sets of cavity guide rails are fixed on both sides of the housing. The module slide slides along the guide rails and carries the metering module, forming a stable guiding structure. This ensures that the metering module is subjected to uniform force during the pulling process, preventing the internal components from loosening due to shaking. The locking device adopts a spring steel ball design. When the metering module is pushed into the cavity and reaches the working position, the spring steel ball will embed into the corresponding slot of the module slide or the metering module to achieve automatic locking. The second sealing strip is distributed on the housing and cavity guide rails around the metering module, forming multiple sealing barriers. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a zoned sealed energy meter. (Refer to...) Figure 1-3The system includes a housing 1, a base plate 2, and a partition plate 11 fixedly connected inside the housing 1. The interior of the housing 1 is divided into an upper cavity 12 and a lower cavity 13 by the partition plate 11. A communication module device 3 is installed inside the upper cavity 12.

The quick-release device 4 includes a fixed base 41, a rotating base 42, a rotating handle 43, multiple sets of connecting rods 44, and multiple sets of hinges 45. The fixed base 41 is fixedly connected to the housing 1, and the rotating base 42 rotates... Connected to the fixed base 41, three sets of connecting rods 44 are mounted on the fixed base 41 at 120-degree intervals via three sets of hinges 45 at one end. The other ends of the three sets of connecting rods 44 are fixedly connected to the rotating base 42 via hinges 45. The rotating handle 43 mounted on the rotating base 42 drives the connecting rods 44 to lock. A display operation module 5 is provided on the housing 1 of the upper cavity 12. The display operation module 5 includes a display screen 51, operation buttons 52, a mounting plate 53, and a magnetic strip 54. The display screen 51 is fixedly connected to the fixed base 42. The operation button 52 is mounted on the mounting plate 53 below the display screen 51. The operation button 52 is movably positioned and connected to the mounting plate 53, allowing the operation button 52 to move controllably in a preset direction and reset. A magnetic strip 54 is fixedly connected to the bottom of the mounting plate 53. A sliding device 6 is provided between the housing 1 and the display operation module 5. The sliding device 6 includes multiple sets of guide rail devices 61, sliders 62, and sealing components 63. The sliders 62 are slidably connected to the guide rail devices 61. The two sets of guide rail devices 61 are respectively bolted to the housing 1 on both sides. The sealing component 63 includes a first sealing strip 631 and a magnetic sealing strip 632. Multiple sets of first sealing strips 631 are respectively fixedly connected to the guide rail devices 61, the housing 1 at the top of the display operation module 5, and both sides of the display operation module 5. The magnetic sealing strip 632 is fixedly connected to the housing 1 at the bottom of the display operation module 5. The magnetic sealing strip 632 is fixed to the display operation module 5 relative to the magnetic strip 54, so that the display operation module 5 will not shake.

[0030] The lower cavity 13 houses a metering module 7. A moving device 8 connects the metering module 7 to the housing 1. The moving device 8 includes multiple sets of cavity guide rails 81, multiple sets of module slides 82, a locking device 83, and multiple sets of second sealing strips 84. Two sets of cavity guide rails 81 are bolted to the housing 1 on both sides of the metering module 7. The module slides 82 are slidably connected to the cavity guide rails 81. The locking device 83 is installed on one side of the cavity guide rails 81 and uses a spring ball design. When the metering module 7 is pushed into the lower cavity, the spring ball will embed into the corresponding slot of the module slide 82 to achieve automatic locking. One set of second sealing strips 84 is fixedly connected to the perimeter of the housing 1 where the metering module 7 is connected. The sealing strip 84 is fixedly connected to the cavity guide rail 81. One end of the metering module 7 is provided with an electrical connection device 9, which is a spring pin 91 with a stroke of eight millimeters. When the metering module 7 slides more than eight millimeters relative to the housing 1, the metering module 7 is de-energized. A wiring device 15 is provided on the bottom of the housing 1 of the lower cavity 13. The wiring device 15 is fixedly connected to the bottom of the housing 1. A third sealing strip 14 is provided at the connection between the partition plate 11 and the bottom plate 2, as well as at the connection between the housing 1 and the bottom plate 2. The housing 1 and the partition plate 11 are bolted to the bottom plate 2 through the third sealing strip 14. The communication module device 3, the display operation module 5, the metering module 7, and the wiring device 15 are interconnected through a professional connection device.

[0031] The working principle of a partitioned sealed energy meter in this application is as follows: A closed and partitioned space is formed by the housing 1, base plate 2, and partition plate 11. The communication module 3 in the upper cavity 12 is responsible for information transmission and reception. The metering module 7 in the lower cavity 13 undertakes the core metering function. The display and operation module 5 is used for human-machine interaction. The wiring device 15 serves as the interface for external line access. The communication module 3 is installed in the upper cavity 12 and fixed by the quick-release device 4. Rotating the handle 43 drives the connecting rod 44, and the linkage of the hinge 45 causes the rotating base 42 to rotate. If the fixed base 41 is loose, reverse the installation process and lock the connecting rod 44 to achieve a stable fixation. The communication module device 3 communicates with external devices or systems, uploading the measurement data from the metering module 7, and simultaneously receiving external commands and transmitting them to other modules. The display operation module 5 is connected to the housing 1 via the sliding device 6 and can slide along the guide rail device 61 to adjust its position. Multiple sets of first sealing strips 631 work together to ensure the sealing of the sliding parts. The magnetic sealing strip 632 uses magnetic force to attract the magnetic strip 54, thus fixing the display operation module 5 relatively. The display screen 51 is... The device displays metering data, equipment status, and other information. Operation button 52 receives user settings and query commands and transmits them to communication module device 3 or metering module 7. Metering module 7 is located in the lower cavity 13 and is installed and fixed by pull-out device 8. When metering module 7 is pushed along cavity guide rail 81, module slide 82 slides accordingly. When pushed into place, the spring steel ball of locking device 83 is embedded in the slot of module slide 82 to complete automatic locking, completing the metering work and transmitting the metering data to communication module or display operation module 5 through electrical connection device 9. Electrical connection device 9 uses spring pin 91. When the spring pin is released from contact with metering module 7, it automatically cuts off the power, preventing data errors or equipment damage caused by abnormal module operation, thus playing a safety protection role. The connection between partition plate 11 and bottom plate 2, and between housing 1 and bottom plate 2, is sealed by third sealing strip 14. The connection between metering module 7 and housing 1 and the second sealing strip 84 on cavity guide rail 81, together with the sealing component 63 of display operation module 5, form a relatively closed environment inside the entire device, effectively preventing dust, moisture, etc. from entering and protecting the internal modules.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
