Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and in particular to a multifunctional power metering box. Background Technology

[0002] Electricity metering boxes are specialized enclosures in power systems used to install and protect electricity metering instruments and related equipment. Traditional electricity metering boxes often employ fixed partitions or rail-mounted structures, resulting in rigid internal space divisions and reliance on natural ventilation or simple overall fan exhaust for heat dissipation. With the deepening of smart grid construction, modern electricity metering boxes have evolved from simple metering functions into integrated terminals encompassing electricity metering, data acquisition, edge computing, two-way communication, load control, and distributed energy access interfaces. The number and variety of internal electronic components have surged, with significant differences in heat generation and layout. However, existing fixed installation structures cannot flexibly adapt to the optimized layout of components of different sizes and heat generation, leading to low space utilization, messy wiring, and severe thermal coupling. To address heat dissipation issues, ventilation holes are often required in the enclosure, which sacrifices the enclosure's protective rating, allowing dust, moisture, and insects to easily penetrate. In harsh outdoor environments, this seriously threatens the long-term reliability of the equipment. More importantly, the effective implementation of many advanced energy-saving technologies in smart grids, such as demand-side response, virtual power plant dispatching, optimal distribution network status estimation, and precise load control, highly depends on the continuous, stable, and reliable operation of the massive number of end-point metering boxes. The core components inside these metering boxes, such as communication modules and control units, are extremely sensitive to temperature. Existing decentralized and inefficient heat dissipation methods cannot guarantee that the operating temperature of these critical components remains within safe thresholds under high-temperature weather or high-load conditions. Overheating leading to device performance degradation, communication interruptions, control malfunctions, or premature failures has become one of the main hardware bottlenecks faced by smart grid energy-saving strategies at the implementation level. Existing forced-air cooling power metering boxes require ventilation holes and dust filters to achieve heat dissipation. However, these filters gradually become clogged, reducing airflow and failing to prevent the penetration of fine dust and moisture. More seriously, this design, which sacrifices protection for heat dissipation, leaves critical electronic components inside the box in a dirty, humid, and temperature-fluctuating microenvironment. This is a root cause of premature equipment failure, data interruption, and control malfunctions, severely hindering the high reliability requirements of smart grids for terminal equipment across all weather conditions and regions. Consequently, the metering boxes cannot operate continuously, stably, and reliably, preventing the efficient implementation of smart grid energy-saving technologies.

[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a multifunctional power metering box to solve the problem that the dustproof net gradually becomes clogged, leading to a decrease in airflow and failing to prevent the penetration of fine dust and moisture, which seriously restricts the high reliability requirements of smart grid terminal equipment in all weather and all regions, resulting in the metering box being unable to operate continuously, stably and reliably.

[0011] Optionally, the presser includes a pressing ring disposed inside the rotating cylinder, and the pressing ring is located above the movable frame. At least two hydraulic telescopic rods are fixedly connected to the top plate, and the telescopic ends of the hydraulic telescopic rods are fixedly connected to the top of the pressing ring.

[0012] Optionally, the top of the movable frame is rotatably connected with a number of ball bearings, and the ball bearings are in contact with the bottom of the pressing ring.

[0013] Optionally, the driver includes a gear ring fixedly mounted on the inner wall of the rotating cylinder, a servo motor fixedly connected to the base plate, and a gear fixedly connected to the output end of the servo motor, with the gear meshing with the gear ring.

[0014] Optionally, the synchronous positioning structure includes several guide strips fixedly installed on the outer wall of the heat dissipation square tube, and the guide strips pass through the corresponding adjustment plates. Several arc-shaped plates are provided on the side of the bottom plate and the top plate that are close to each other. A movable seat is provided on the side of the arc-shaped plate facing the adjustment plate. A second sliding groove is opened on the side of the movable seat facing the adjustment plate. A support block is slidably provided in the second sliding groove. The support block and the adjustment plate are fixedly connected. A groove is opened on the side of the support block away from the adjustment plate. Several second compression springs are provided in the groove. The two ends of the second compression springs are fixedly connected to the inner wall of the groove and the inner wall of the second sliding groove, respectively. A support strip that cooperates with the arc-shaped plate is fixedly connected on the side of the movable seat away from the adjustment plate. Rotation units for driving several arc-shaped plates to rotate synchronously are provided on the bottom plate and the top plate, respectively.

[0015] Optionally, the rotating unit includes a second connecting plate fixedly installed on the side of the arc-shaped plate away from the support bar.

[0017] The beneficial effects of this invention are as follows: The operator fixes the base plate to the preset installation position using a bracket, drives the rotating cylinder to rotate using a driver, so that the inspection door rotates to one side of one of the adjustment plates. The operator then fixes the electronic components to be installed onto the corresponding heat sinks. The operator drives the electronic components and heat sinks to move vertically relative to the adjustment plates, thereby adjusting the distance between two adjacent heat sinks. After the position of the heat sinks is adjusted, the position of the adjustment plate is positioned using a synchronous positioning structure, so that the heat sinks are in close contact with the outer wall of the heat dissipation square tube. The heat generated by the electronic components is transferred to the heat dissipation square tube through the heat sinks, and the heat dissipation structure dissipates heat from the heat dissipation square tube. This allows for simultaneous heat dissipation of different electronic components located inside the rotating cylinder, while the inspection door can rotate simultaneously. The enclosure is positioned in different locations for easy inspection of electronic components. Internal heat conduction directs heat to the heat dissipation tubes for centralized cooling, achieving physical isolation between the interior and exterior environments. This eliminates the need for external airflow for internal convection, resulting in a true full seal. The absence of openings fundamentally prevents dust, catkins, insects, and other contaminants from entering the enclosure, avoiding their accumulation on components and circuit boards that could lead to insulation degradation, poor heat dissipation, or short circuits. External humid air cannot enter, maintaining a constant air volume and moisture content within the enclosure. This prevents condensation from forming at the dew point during temperature changes, protecting precision electronic components from corrosion and electrochemical migration. The enclosure provides a clean, dry, and controllable near-ideal operating environment for all electronic components. This allows components to continuously perform at their optimal level under designed operating conditions, significantly reducing the probability of performance degradation, malfunctions, or sudden failures caused by environmental stress. The overall mean time between failures (MTBF) of the equipment is improved, and the maintenance requirements and costs are significantly reduced. This represents a leap in the reliability of the internal hardware of the electricity metering box, directly serving the energy-saving goals of the smart grid. The continuous, stable, and reliable operation of the metering box ensures the continuity and accuracy of electricity data collection, providing a reliable data foundation for grid optimization and dispatching and reducing grid losses. This ensures the timeliness and success rate of demand-side response commands such as remote load control, enabling the effective implementation of direct energy-saving measures based on price or incentives, and ultimately guaranteeing the efficient implementation of smart grid energy-saving technologies.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 7The present invention includes a base plate 1 and a top plate 2 disposed above the base plate 1. A heat dissipation square tube 3 is provided between the base plate 1 and the top plate 2. Both ends of the heat dissipation square tube 3 pass through the base plate 1 and the top plate 2 respectively, and both ends of the heat dissipation square tube 3 are fixedly connected to the base plate 1 and the top plate 2 respectively. A heat dissipation structure is installed inside the heat dissipation square tube 3. A rotating cylinder 4 is fitted around the heat dissipation square tube 3. The two ends of the rotating cylinder 4 are rotatably connected to the base plate 1 and the top plate 2, respectively. A driver is installed on the base plate 1 to drive the rotating cylinder 4 to rotate. An inspection door 5 is installed on the rotating cylinder 4. Several circumferentially evenly distributed adjustment plates 6 are provided on the outer wall of the heat dissipation square tube 3. A heat dissipation sleeve 7 is slidably fitted onto the outside of the adjustment plates 6, and the heat dissipation sleeve 7 is in contact with the outer wall of the heat dissipation square tube 3. The base plate 1 and the top plate 2 are respectively provided with synchronous positioning structures for positioning the positions of several adjustment plates 6. The operator fixes the base plate 1 to a preset installation position using a bracket, drives the rotating cylinder 4 to rotate, so that the inspection door 5 rotates to one side of one of the adjustment plates 6. The operator fixes the electronic components to be installed onto the corresponding heat dissipation sleeve 7. The operator drives the electronic components and the heat dissipation sleeve 7 to move vertically relative to the adjustment plate 6, thereby adjusting the distance between two adjacent heat dissipation sleeves 7. After the position of the heat dissipation sleeve 7 is adjusted, the position of the adjustment plate 6 is positioned using the synchronous positioning structure, so that the heat dissipation sleeve 7 and the heat dissipation tube 3 are aligned. The outer wall of the square tube 3 is tightly fitted, and the heat generated by the electronic components is transferred to the heat dissipation square tube 3 through the heat dissipation sleeve 7. The heat dissipation structure dissipates heat from the heat dissipation square tube 3, allowing for simultaneous heat dissipation of different electronic components located in the rotating cylinder 4. At the same time, the inspection door 5 can be rotated to different positions for easy inspection of electronic components in different locations. Through internal heat conduction, heat is conducted to the heat dissipation square tube 3 for centralized heat dissipation, thereby achieving physical isolation between the inside and outside environment of the chamber. There is no need to introduce external air for internal convection, achieving true full sealing. No openings are required, fundamentally preventing dust, catkins, insects, etc. from entering the chamber, avoiding their accumulation on components and circuit boards, which could cause insulation degradation, heat dissipation deterioration, or short circuits. External humid air cannot enter, and the volume and moisture content of the air inside the chamber are constant, making it difficult to reach the dew point and form condensation when the temperature changes. This protects the precision electronic components from corrosion and electrochemical migration damage, providing a clean, dry, and controllable near-ideal operating environment for all electronic components inside the metering chamber. This allows components to continuously perform at their optimal level under designed operating conditions, significantly reducing the probability of performance degradation, malfunctions, or sudden failures caused by environmental stress. The overall mean time between failures (MTBF) of the equipment is improved, and maintenance requirements and costs are significantly reduced. This represents a leap forward in the reliability of the internal hardware of the electricity metering box, directly serving the energy-saving goals of the smart grid. The continuous, stable, and reliable operation of the metering box ensures the continuity and accuracy of electricity data collection, providing a reliable data foundation for grid optimization and loss reduction. This guarantees the immediacy and success rate of demand-side response commands such as remote load control, enabling the effective implementation of price- or incentive-based direct energy-saving measures, and ultimately ensuring the efficient implementation of smart grid energy-saving technologies.

[0023] Example 2, based on Example 1, is... Figure 2 , Figure 7 and Figure 10 The heat dissipation structure includes a first heat dissipation fan 8 disposed inside a heat dissipation square tube 3. Several mounting plates 9 are fixedly connected to the top of the first heat dissipation fan 8, and the mounting plates 9 are located above the top plate 2. The mounting plates 9 and the top plate 2 are connected by bolts 10. Several heat dissipation fins 11 are fixedly connected to the inner wall of the heat dissipation square tube 3, and the heat dissipation fins 11 are located below the first heat dissipation fan 8. When the first heat dissipation fan 8 is started, it dissipates heat from the heat dissipation square tube 3 and the heat dissipation fins 11. When the first heat dissipation fan 8 needs to be removed, the operator drives the bolts 10 to rotate so that the bolts 10 are disengaged from the mounting plates 9 and the top plate 2, thereby releasing the fixation of the first heat dissipation fan 8. The operator then drives the first heat dissipation fan 8 to detach from the heat dissipation square tube 3, thus completing the removal of the first heat dissipation fan 8.

[0024] Example 3, based on Example 1, is... Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 It is provided that at least one movable frame 12 is provided between the rotating cylinder 4 and the heat dissipation square tube 3. The bottom end of the movable frame 12 is equipped with an elastic element that cooperates with the rotating cylinder 4. Several second heat dissipation fans 13 are provided on the movable frame 12. Rotating shafts 14 are fixedly connected to both sides of the second heat dissipation fans 13. Side plates 15 are rotatably sleeved on the outside of the rotating shafts 14. The side plates 15 are fixedly connected to the inner wall of the rotating cylinder 4. A transmission component that cooperates with the movable frame 12 is installed on the rotating shafts 14. A presser that cooperates with the movable frame 12 is installed on the top plate 2. The transmission component includes a first connecting plate 17 fixedly installed on the rotating shafts 14. Movable columns 16 are fixedly installed on the first connecting plate 17. Several rectangular holes 18 are opened on the inner walls of both sides of the movable frame 12, and the movable columns 16 are slidably installed in the corresponding rectangular holes 18. The elastic element includes a support frame 19 provided below the movable frame 12. The support frame 19 and The inner wall of the rotating cylinder 4 is fixedly connected, and two first sliding grooves 20 are opened on the support frame 19. The bottom end of the movable frame 12 is slidably installed in the corresponding first sliding groove 20. The bottom of the movable frame 12 and the bottom of the inner wall of the first sliding groove 20 are connected by several first compression springs 21. The presser includes a pressing ring 22 set in the rotating cylinder 4 and the pressing ring 22 is located above the movable frame 12. At least two hydraulic telescopic rods 23 are fixedly connected on the top plate 2, and the telescopic end of the hydraulic telescopic rod 23 is fixedly connected to the top of the pressing ring 22. Several balls 24 are rotatably connected to the top of the movable frame 12, and the balls 24 are in contact with the bottom of the pressing ring 22. The driver includes a gear ring 25 fixedly installed on the inner wall of the rotating cylinder 4. A servo motor 26 is fixedly connected on the bottom plate 1. A gear 27 is fixedly connected to the output end of the servo motor 26, and the gear 27 and the gear ring 25 mesh with each other. The servo motor 26 drives the gear 27 to rotate, which in turn drives the rotating cylinder 4 to rotate relative to the heat dissipation square tube 3 via the gear ring 25. The rotating cylinder 4 drives the movable frame 12 to rotate synchronously via the support frame 19, so that the second heat dissipation fan 13 rotates to a preset position. The movable frame 12 drives the ball bearing 24 to roll at the bottom of the pressing ring 22. When the second heat dissipation fan 13 rotates to the preset position, the first compression spring 21 is in a compressed state. The first compression spring 21 applies an upward force to the movable frame 12 so that the ball bearing 24 is always in close contact with the bottom of the pressing ring 22. This is driven by the hydraulic telescopic rod 23. The pressing ring 22 moves vertically back and forth, which drives the movable frame 12 to move vertically back and forth. The movable frame 12 drives the movable column 16 to slide back and forth within the rectangular hole 18. The movable column 16 can drive the rotating shaft 14 and the second cooling fan 13 to rotate in both directions through the first connecting plate 17, changing the tilt angle of the second cooling fan 13 so that the second cooling fan 13 can accelerate heat dissipation in the designated area. This can quickly lower the temperature of the critical component, prevent it from entering a performance degradation state or being damaged due to short-term overheating, thereby smoothing out temperature peaks and ensuring functional integrity under sudden tasks.

[0025] Example 4, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12The synchronous positioning structure includes several guide strips 28 fixedly installed on the outer wall of the heat dissipation square tube 3, and the guide strips 28 pass through the corresponding adjustment plates 6. Several arc-shaped plates 29 are provided on the side of the bottom plate 1 and the top plate 2 that are close to each other. A movable seat 30 is provided on the side of the arc-shaped plate 29 facing the adjustment plate 6. A second sliding groove 33 is opened on the side of the movable seat 30 facing the adjustment plate 6. A support block 32 is slidably arranged in the second sliding groove 33. The support block 32 is fixedly connected to the adjustment plate 6. A groove 34 is opened on the side of the support block 32 away from the adjustment plate 6. Several second compression springs 35 are provided in the groove 34, and the two ends of the second compression springs 35 are fixedly connected to the inner wall of the groove 34 and the inner wall of the second sliding groove 33, respectively. A support strip 31 that cooperates with the arc-shaped plate 29 is fixedly connected to the side of the movable seat 30 away from the adjustment plate 6. Several arc-shaped plates are respectively provided on the bottom plate 1 and the top plate 2. The rotating unit 29 rotates synchronously. The rotating unit includes a second connecting plate 43 fixedly installed on the side of the arc plate 29 away from the support bar 31.

The side of the heat dissipation sleeve 7 away from the heat dissipation square tube 3 is fixedly connected with a number of screw rods 44. The screw rods 44 are threaded with nuts 39. The arc-shaped plate 29 supports the support bar 31. The second compression spring 35 is in a compressed state, applying pressure to the support block 32 and the adjusting plate 6 to ensure that the heat dissipation sleeve 7 is tightly attached to the heat dissipation square tube 3. When the entire adjusting plate 6 needs to be removed, the operator drives the iron plate 41 and the insertion rod 40 to move, so that the insertion rod 40 is disengaged from the corresponding bottom plate 1 or top plate 2. The iron plate 41 is no longer magnetically attracted to the magnetic ring 42, releasing the fixation on the insertion rod 40. Since the insertion rod 40 is disengaged from the bottom plate 1 or top plate 2, the position restriction of the rotating ring 36 can be released. The operator drives the rotating ring 36 to rotate relative to the bottom plate 1 or top plate 2. The rotating ring 36 drives the second connecting plate 43 and the arc-shaped plate through the slider 38.

The operator drives the adjustment plate 6 to move relative to the heat dissipation square tube 3 so that the guide bar 28 is disengaged from the adjustment plate 6, thereby releasing the fixing of the adjustment plate 6. Open the maintenance door 5, and the operator can take the adjustment plate 6 out of the rotating cylinder 4. The adjustment plate 6 and the heat dissipation sleeve 7 can be replaced. The lead screw 44 on the heat dissipation sleeve 7 can pass through the mounting hole on the electronic component. The operator rotates the nut 39 and puts it on the outside of the lead screw 44.
