Description

Technical Field

[0001] This application relates to the technical field of metering boxes, and in particular to an energy metering box with biomimetic convection heat dissipation. Background Technology

[0002] In the vast architecture of the power system, the electricity metering box is an indispensable and crucial component. Like a precise "electricity balance," it accurately measures the electricity consumption of various power users, providing a solid and reliable data foundation for the rational allocation of power supply and billing. With the booming development of the power industry, the performance requirements for electricity metering boxes are becoming increasingly stringent. Currently, power equipment is making great strides towards miniaturization and high density. Miniaturization aims to save space and reduce costs, while high density dramatically increases the number of electronic components per unit volume. However, this development trend has brought heat dissipation challenges to electricity metering boxes, becoming a key challenge that urgently needs to be overcome.

[0003] To address the heat generated by the operation of electronic components inside electricity metering boxes, various heat dissipation methods have been actively explored and applied in related technical fields. Among these, forced air cooling technology is relatively traditional and common. This technology involves installing a fan inside the electricity metering box, which is securely fixed to the inner wall of the box with screws. After the fan starts, its high-speed rotation creates airflow, thereby accelerating the dissipation of heat inside the box. In long-term application practice in the power industry, forced air cooling technology has played a crucial role in ensuring the normal operation of electricity metering boxes, guaranteeing their stable operation under various working conditions.

[0004] While forced air cooling technology has shown some effectiveness, its drawbacks are becoming increasingly apparent as power equipment becomes smaller and denser. As the core component of forced air cooling, the fan is prone to failure during long-term operation, severely impacting heat dissipation stability. Regular fan maintenance is necessary to ensure normal equipment operation. However, the miniaturization of electricity metering boxes has resulted in extremely limited internal space. Maintenance personnel must use wrenches and other tools to disassemble and inspect the equipment within this confined space, making the operation difficult, time-consuming, and significantly impacting overall maintenance efficiency. Therefore, it is clear that traditional forced air cooling technology has significant room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a biomimetic convection cooling power meter box, which solves the problem of inconvenient fan installation and removal in confined spaces in the above-mentioned related technologies.

[0006] The biomimetic convection cooling power metering box provided in this application adopts the following technical solution: A biomimetic convection cooling power metering box includes a box body. A mounting cavity is formed on one vertical side of the box body, and a detachable door for sealing the mounting cavity is provided. Several guide holes are formed on the bottom side of the box body. Exhaust ports are formed on two opposite vertical outer sides of the upper part of the box body, and a downward-facing guide shroud is fixed to the outer edge of the exhaust port opening. A mounting plate is horizontally mounted inside the box body below the exhaust ports. A through hole for mounting is formed on the mounting plate, and a guide fan is fixed to the inner wall of the through hole. Limiting guide rails are fixed horizontally on two opposite inner walls of the upper part of the mounting cavity. Limiting grooves are formed on the sides of the two limiting guide rails that are close to each other, allowing the opposite edges of the mounting plate to slide into and be fixed.

[0007] By adopting the above technical solution, on the one hand, a biomimetic convection cooling system is constructed by setting up a mounting cavity, a detachable door, airflow guide holes, exhaust ports, and airflow guide covers in the enclosure, and cooperating with the airflow guide fan on the mounting plate. This eliminates the need for traditional fans to be fixed with screws, effectively avoiding the problem of inconvenient fan disassembly and assembly in confined spaces under traditional forced air cooling in the miniaturization and high-density of power equipment, reducing maintenance difficulty and time consumption, and improving maintenance efficiency. On the other hand, the design of the limiting guide rail and limiting slide groove allows the mounting plate to slide in and be fixed easily, facilitating the installation and maintenance of the airflow guide fan, while ensuring the stability of the installation.

[0008] Optionally, a plurality of guide fins are fixed on the bottom side of the mounting plate.

[0009] By adopting the above technical solution, the guide fins greatly increase the heat dissipation area. When the guide fan operates and drives the air to flow, the air can come into more full contact with the guide fins, thereby quickly carrying away the heat generated by the mounting plate and electronic components inside the box, significantly improving the heat dissipation efficiency and better meeting the high requirements for heat dissipation after the miniaturization and high density of power equipment.

[0010] Optionally, the mounting plate is provided with an elastic snap-fit ​​component, and the inner wall of the limiting slide groove is provided with a positioning groove. The elastic snap-fit ​​component can be snapped into and disengaged from the positioning groove when the mounting plate slides relative to the limiting slide groove.

[0011] By adopting the above technical solution, when the mounting plate slides along the limiting groove, the elastic snap-fit ​​component engages with the positioning groove, clearly informing the installer that the mounting plate has reached the correct position, avoiding improper or excessive installation, and improving the accuracy and convenience of installation. Simultaneously, this snap-fit ​​structure enhances the stability of the mounting plate after installation, preventing displacement due to vibration or other factors during use, ensuring the normal operation of components such as the guide fan. Furthermore, when the mounting plate needs to be disassembled for maintenance or replacement, simply applying appropriate external force to disengage the elastic snap-fit ​​component from the positioning groove allows for easy removal of the mounting plate, making the operation simple and quick, greatly improving maintenance efficiency.

[0012] Optionally, a horizontally placed receiving plate is provided at the bottom of the housing. Vertically upward connecting rods are fixed on opposite sides of the receiving plate. Connecting shafts are fixed on the sides of the two connecting rods that are close to each other. Guide plates are fixed on opposite vertical sides of the housing. Guide grooves for inserting the connecting shafts are opened vertically on the guide plates. The connecting shafts can reciprocate along the guide grooves and rotate around their own axis. When the receiving plate is below the housing, it is used for placing maintenance tools. When the receiving plate is flipped to the top of the housing with the connecting rods, it can protect the upper surface of the housing.

[0013] By adopting the above technical solution, during maintenance, the receiving plate is located below the housing, providing a stable platform for maintenance tools. This allows maintenance personnel to easily access tools, avoiding loss or inconvenience caused by haphazard placement and improving maintenance efficiency. Furthermore, when the receiving plate is flipped to the top of the housing along the connecting rod, it also protects the upper surface of the housing, preventing collisions and scratches from external objects, reducing the risk of damage, and extending its service life. Moreover, the connecting shaft can reciprocate along the guide groove and rotate around its own axis, ensuring smooth and flexible flipping of the receiving plate, making operation easy and effortless.

[0014] Optionally, a vertically downward extension plate is fixed on the side edge of the receiving plate near the connecting rod. When the extension plate is above the housing, it can protect the outer side of the flow guide. When the extension plate is below the housing, it is used to prevent the maintenance tools placed on it from falling off the receiving plate.

[0015] By adopting the above technical solution, when the extension plate is above the enclosure, it can protect the outer side of the air guide, effectively preventing damage to the air guide caused by external collisions, dust adhesion, or foreign object corrosion, ensuring the normal function of the air guide, and thus ensuring that the heat dissipation effect of the power metering box is not affected. When the extension plate is below the enclosure, it can prevent maintenance tools placed on the support plate from falling out.

[0016] Optionally, a locking through hole communicating with a limiting slide groove is provided on the outer side of the housing, and a locking slot communicating with and coaxial with the locking through hole is provided on the mounting plate; a locking rod and a spring are provided on the outside of the housing; the locking rod can pass through the locking through hole and be inserted into the locking slot, a baffle is fixed on the outer periphery of the locking rod, and a clearance groove for the baffle to be inserted and slid is provided on the inner wall of the outer opening of the locking through hole; the two ends of the spring are respectively fixedly connected to the baffle and the bottom side of the clearance groove close to each other; when the receiving plate rotates to the top of the housing, the connecting rod facing the side of the housing presses the outer end of the locking rod, so that the locking rod is inserted into the locking slot; the inner end of the locking rod disengages from the locking slot when the connecting rod and the locking rod are misaligned.

[0017] By adopting the above technical solution, after the mounting plate is installed in place, the locking rod is inserted into the locking slot, which effectively prevents the mounting plate from sliding accidentally, enhances its stability, and ensures the normal operation of components such as the guide fan. The design of the spring and baffle allows the locking rod to automatically reset, making operation simple. Locking is achieved by the connecting rod pressing against the outer end of the locking rod when the receiving plate rotates; if misalignment occurs, the locking rod automatically disengages to unlock, cleverly utilizing the movement of the receiving plate without requiring additional complex operations, thus improving ease of use. This design not only ensures the stable installation of the mounting plate within the box, meeting the requirements for stable operation of the power metering box, but also allows for quick unlocking of the mounting plate when maintenance is needed.

[0018] Optionally, a baffle plate is fixedly provided on the inner wall of the bottom opening of the flow guide, and a baffle hole is provided on the baffle plate; a sealing plate is slidably provided on the bottom side of the guide plate, and a sealing hole is provided on the sealing plate that can coincide with the baffle hole; an adjusting rod is fixedly provided on the bottom surface of the sealing plate above the outer end of the locking rod, and the lower end of the adjusting rod is fixedly connected to the upper side of the outer side of the locking rod; the sealing hole coincides with the baffle hole when the inner end of the locking rod is inserted into the locking slot, and is misaligned with the baffle hole when the locking rod is disengaged from the locking slot.

[0019] By adopting the above technical solution, when the inner end of the locking rod is inserted into the locking slot, i.e., when the mounting plate is secure, the sealing hole and the blocking hole coincide, ensuring normal air circulation inside and outside the box, achieving effective heat dissipation, and ensuring that the electronic components inside the power metering box operate at a suitable temperature. When the locking rod is disengaged from the locking slot for maintenance and disassembly of the mounting plate, the sealing hole and the blocking hole misalign, and the sealing plate seals the blocking hole, preventing external dust and debris from entering the box, avoiding damage to electronic components, and extending the equipment's service life. This design cleverly links the mounting plate's locking state with the box's heat dissipation and protection functions, automatically switching without additional operation, improving the convenience, safety, and reliability of the power metering box, and meeting the actual operation and maintenance needs of power equipment.

[0020] Optionally, positioning protrusions are fixed on the two opposite sides of the bottom surface of the flow guide, and positioning grooves are opened on the sides of the two positioning protrusions that are close to each other, allowing the sealing plate to be inserted and slid along the opposite sides. The sealing plate can slide back and forth towards the housing.

[0021] By adopting the above technical solution, the sealing plate is positioned in the locating grooves along its two opposite edges, ensuring accurate positioning during sliding without shifting or wobbling. This guarantees precise alignment or misalignment between the sealing plate and the blocking holes on the barrier plate, reliably opening and closing the heat dissipation channel. Simultaneously, the sealing plate can slide back and forth towards the enclosure, working in conjunction with the overall design to smoothly open the channel when heat dissipation is needed and tightly seal it for protection, offering flexible and stable operation. Moreover, this structure is simple and reasonable, easy to manufacture and install, reducing production costs and process complexity.

[0022] Optionally, when the receiving plate is below the box, it can be moved up to a state that abuts against the bottom surface of the box. At this time, the guide hole is blocked by the receiving plate, and the blocking hole and the barrier hole are misaligned. The box is provided with fasteners on the outside to lock the connecting rod in this state.

[0023] By adopting the above technical solution, when the receiving plate moves up and abuts against the bottom surface of the box, it can block the guide hole and simultaneously misalign the blocking hole with the barrier hole. This effectively prevents external dust and moisture from entering the box through the guide hole and barrier hole, providing more reliable protection for the electronic components inside the electricity metering box, reducing the risk of component damage caused by environmental factors, and extending the service life of the equipment. Furthermore, fasteners are used to lock the connecting rod in this state, ensuring the stability of the receiving plate's sealing state and preventing displacement due to external vibration or collision, thus avoiding loss of protective function. This design requires no additional complex structure, cleverly utilizing the positional change of the receiving plate to achieve the protective function. It adapts to the protection needs of the box in different usage scenarios, such as when the equipment is idle or during transportation, and coordinates with the overall heat dissipation and protection system, improving the overall safety and reliability of the electricity metering box.

[0024] Optionally, the connecting rod has a fastening through hole that passes through the connecting shaft, and the bottom side of the limiting slide groove has a fastening screw hole that coincides with the fastening through hole; the fastener is a fastening bolt that passes through the fastening through hole and is screwed into the fastening screw hole.

[0025] By adopting the above technical solution, when the receiving plate moves up and abuts against the bottom surface of the box, the fastening through hole on the connecting rod can coincide with the fastening screw hole on the bottom side of the limiting slide groove. At this time, the connecting rod can be firmly locked by using a fastening bolt through the fastening through hole and screwed into the fastening screw hole. This locking method is simple and reliable, and can effectively prevent the receiving plate from loosening or shifting due to external force when it is not in operation. It ensures the sealing of the guide hole by the receiving plate and the stable protection of the bottom of the box, preventing external dust, moisture and other substances from entering the box and ensuring the safety of the electronic components inside the power metering box.

[0026] In summary, this application includes the following beneficial technical effects: On the one hand, by incorporating a mounting cavity, a removable door, airflow guide holes, exhaust ports, and an airflow guide cover within the enclosure, and in conjunction with the airflow guide fan on the mounting plate, a biomimetic convection cooling system is constructed. This eliminates the need for screw-fixed fans, effectively avoiding the inconvenience of fan disassembly and assembly in confined spaces inherent in traditional forced air cooling systems used in miniaturized and high-density power equipment. This reduces maintenance difficulty and time consumption, and improves maintenance efficiency. On the other hand, the design of the limiting guide rail and limiting slide groove allows the mounting plate to slide in and be secured easily, facilitating the installation and maintenance of the airflow guide fan while ensuring installation stability.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] Example 1: Reference Figure 1 A biomimetic convection heat dissipation power metering box includes a box body 1, wherein a mounting cavity 11 is opened on one vertical surface of the box body 1, and a box door 2 for sealing the mounting cavity 11 is detachably installed; a plurality of fixing ears 15 are fixed on the side edge of the box body 1 away from the box body 1, and fixing through holes 151 are opened on the fixing ears 15; one side of the box door 2 is rotatably connected to the opening edge of the mounting cavity 11, and the other side of the box door 2 is detachably connected to the box body 1 through a conventional lock structure; The enclosure 1 is equipped with a heat dissipation component 3 that facilitates air circulation. Several air guide holes 12 are provided on the bottom side of the enclosure 1. Exhaust ports 13 are provided on the two opposite vertical outer surfaces of the upper part of the enclosure 1. A downward-facing air guide shroud 14 is fixed to the outer edge of the opening of the exhaust port 13. External air enters the enclosure 1 through the air guide holes 12. Then, the high-temperature air inside the enclosure 1 is discharged from the exhaust port 13 under the action of the heat dissipation component 3. This constitutes rapid air circulation inside the enclosure 1 and reduces the possibility of external dust or other impurities entering the enclosure 1 through the air guide shroud 14.

[0032] Reference Figure 2 and Figure 3The heat dissipation component 3 includes a mounting plate 31 that is horizontally installed inside the housing 1 and located below the exhaust port 13. The mounting plate 31 has a through hole 311 for installation. A guide fan 32 is fixed on the inner wall of the through hole 311. Several guide fins 33 are fixed on the bottom side of the mounting plate 31. Limiting guide rails 16 are fixed horizontally on the two opposing inner walls of the upper part of the mounting cavity 11. Limiting grooves 161 are provided on the sides of the two limiting guide rails 16 that are close to each other, so that the opposite two edges of the mounting plate 31 can slide in and be fixed. When the heat dissipation assembly 3 is installed, the two edges of the mounting plate 31 can be slid into the limiting grooves 161. The mounting plate 31 is fixed by the friction between the mounting plate 31 and the limiting grooves 161, which also facilitates subsequent maintenance and disassembly.

[0033] Reference Figure 3 and Figure 4 The mounting plate 31 is provided with an elastic snap-fit ​​component 34, which includes a compression spring 341 and an arc-shaped protrusion 342. The mounting plate 31 is provided with a placement groove 312 for the compression spring 341 and the arc-shaped protrusion 342 to be placed. The compression spring 341 presses one side of the arc-shaped protrusion 342, causing a part of the arc-shaped protrusion 342 to protrude from the opening of the mounting groove. The outer surface of the protruding part of the arc-shaped protrusion 342 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. The inner wall of the limiting slide 161 is provided with a positioning groove 162; when the mounting plate 31 slides relative to the limiting slide 161, the elastic snap fastener 34 can be snapped into the positioning groove 162, and when the operator applies a certain force, the elastic snap fastener 34 can also be dislodged from the positioning groove 162.

[0034] The implementation principle of this application embodiment is as follows: Installation status: Slide the two sides of the mounting plate 31 into the limiting groove 161 of the limiting guide rail 16. During the sliding process, the arc-shaped protrusion 342 of the elastic snap-fit ​​34 is pressed, and the compression spring 341 is compressed. When it slides to the positioning groove 162, the compression spring 341 returns to its original position and pushes the arc-shaped protrusion 342 into the positioning groove 162. The mounting plate 31 is fixed by friction and snap-fit, which is convenient for subsequent maintenance and disassembly. Operating state: External gas enters the interior of the housing 1 through the guide hole 12 on the bottom side of the housing 1. The high-temperature gas inside the housing 1 is discharged through the exhaust port 13 on the two opposite vertical outer sides of the upper part of the housing 1 under the action of the guide fan 32 on the mounting plate 31, forming a rapid air circulation inside the housing 1 to achieve heat dissipation. At the same time, the downward guide shroud 14 on the outer edge of the exhaust port 13 can reduce the possibility of external dust or other impurities entering the interior of the housing 1, ensuring the normal operation of the equipment inside the housing.

[0035] Example 2: Reference Figure 5 , Figure 6 and Figure 7 The difference between this embodiment and Embodiment 1 is that a receiving assembly 4 is provided below the box body 1. The receiving assembly 4 includes a receiving plate 41 placed horizontally below the box body 1. Vertically upward connecting rods 42 are fixed on opposite sides of the receiving plate 41. A connecting shaft 421 is fixed on the side of the two connecting rods 42 that are close to each other. A guide plate 17 is fixed on opposite vertical sides of the box body 1. A guide groove 171 is opened on the guide plate 17 along the vertical direction for the connecting shaft 421 to be inserted. The connecting shaft 421 can reciprocate along the guide groove 171 and rotate around its own axis. When the staff inspects the meter box, they can rotate the receiving plate 41 along with the connecting rod 42 to the bottom of the box 1, while keeping the receiving plate 41 in a horizontal position. At this time, the inspection tools can be placed on the upper side of the receiving plate 41. When the meter box is in normal use, the receiving plate 41 is flipped up with the connecting rod 42 to the top of the box 1, so that the bottom surface of the receiving plate 41 abuts against the upper side of the box 1, thereby protecting the upper surface of the box 1 through the receiving plate 41.

[0036] Reference Figure 5 and Figure 7 An extension plate 411 facing the connecting rod 42 is fixed on the side edge of the receiving plate 41 near the connecting rod 42. When the receiving plate 41 is above the housing 1 and abuts against the upper side of the housing 1, the extension plate 411 can protect the outer side of the guide shroud 14, further reducing the possibility of external impurities entering the housing 1 from the guide shroud 14. When the receiving plate 41 is below the housing 1 for placing maintenance tools, the extension plate 411 is used to prevent the placed maintenance tools from falling off the receiving plate 41.

[0037] Reference Figure 8 , Figure 9 and Figure 10 The outer side of the housing 1 is provided with a locking member 43 to further lock the mounting plate 31 which is located in the limiting slide groove 161; a locking through hole 18 communicating with the limiting slide groove 161 is provided on the outer side of the housing 1, wherein the mounting plate 31 is provided with a locking slot 313 that can communicate with the locking through hole 18 and is coaxial; the locking member 43 includes a locking rod 431 and a spring 432; The locking rod 431 can pass through the locking through hole 18 and be inserted into the locking slot 313. A baffle 433 is fixed on the outer periphery of the locking rod 431. A clearance groove 181 is provided on the inner wall of the outer opening of the locking through hole 18 for the baffle 433 to be inserted and slide. The two ends of the spring 432 are respectively fixedly connected to the bottom side of the baffle 433 and the clearance groove 181 close to each other. When the receiving plate 41 rotates to the top of the housing 1, the connecting rod 42 presses against the outer end of the locking rod 431 on the side of the housing 1, thereby causing the locking rod 431 to be inserted into the locking slot 313; when the connecting rod 42 and the locking rod 431 are misaligned, the inner end of the locking rod 431 comes out of the locking slot 313, releasing the lock on the mounting plate 31.

[0038] Reference Figure 10 , Figure 11 and Figure 12 The exterior of the flow guide shroud 14 is provided with a barrier component 5, wherein the barrier component 5 includes a barrier plate 51 fixed on the inner wall of the bottom opening of the flow guide shroud 14, and a barrier hole is provided on the barrier plate 51; a sealing plate 52 is slidably provided on the bottom side of the guide plate 17, and a sealing hole is provided on the sealing plate 52 that can coincide with the barrier hole, and the sealing plate 52 can slide back and forth towards the box 1. The bottom surface of the flow guide 14 has two locating protrusions 141 integrally formed on opposite sides. The two locating protrusions 141 are provided with locating grooves 1411 on the sides where they are close to each other, for the sealing plate 52 to be inserted and slid. An adjusting rod 53 is fixed on the bottom surface of the sealing plate 52, located above the outer end of the locking rod 431. The lower end of the adjusting rod 53 is fixedly connected to the upper side of the locking rod 431. When the inner end of the locking rod 431 is inserted into the locking slot 313, the sealing hole on the sealing plate 52 coincides with the blocking hole on the blocking plate 51. At this time, the gas in the box 1 can be discharged normally from the opening of the guide shroud 14. When the locking rod 431 is removed from the locking slot 313, the sealing hole and the blocking hole are misaligned. At this time, the lower opening of the guide shroud 14 is completely blocked, and the gas in the box 1 cannot be discharged from the lower opening of the guide shroud.

[0039] Reference Figure 13 When the receiving plate 41 is below the box body 1, it can move up to abut against the bottom surface of the box body 1. At this time, the guide hole 12 is blocked by the receiving plate 41, and the blocking hole and the barrier hole are misaligned. The box body 1 is provided with a fastener 6 to lock the connecting rod 42 in this state. The connecting rod 42 has a fastening through hole that passes through the connecting shaft 421. The bottom side of the limiting slide groove 161 has a fastening screw hole that can coincide with the fastening through hole. The fastener 6 is a fastening bolt 61 that passes through the fastening through hole and is screwed into the fastening screw hole. The fastening bolt 61 is a wing bolt. When the external environment is harsh or the metering box is being transported over a long distance, the receiving plate 41 is adjusted to be below the box body 1, and then one side of the receiving plate 41 is slid to be in contact with the bottom surface of the box body 1. Finally, the connecting rod 42 is locked at this time by the fastener 6. In this state, the flow guide hole 12 on the lower side of the box body 1 is blocked by the receiving plate 41, and the lower opening of the flow guide cover 14 is blocked, reducing the possibility of external impurities entering the box body 1 due to the harsh external environment.

[0040] The implementation principle of this application embodiment is as follows: Normal application state: Flip the receiving plate 41 to the top of the box 1, with the bottom surface abutting against the upper side of the box 1, and extend the plate 411 to protect the outside of the air guide 14; the connecting rod 42 presses the locking rod 431, causing it to insert into the locking slot 313 of the mounting plate 31, locking the mounting plate 31, and at the same time, the sealing hole and the blocking hole coincide, allowing gas to be discharged normally; this achieves further locking of the mounting plate 31, releases the sealing of the lower opening of the air guide 14, and also protects the upper side of the box 1, reducing the possibility of bird droppings or other impurities adhering to the upper side of the box 1 during outdoor applications.

[0041] Maintenance status: Rotate the receiving plate 41 to the bottom of the box 1 and place it horizontally to place maintenance tools. The extension plate 411 prevents the tools from falling out. In harsh external environments or when transporting the metering box by its length: Adjust the receiving plate 41 to the bottom of the box 1, then slide one side of the receiving plate 41 to a state of contact with the bottom surface of the box 1. Finally, lock the connecting rod 42 at this time with the fastener 6. In this state, the guide hole 12 on the lower side of the box 1 is blocked by the receiving plate 41, and the lower opening of the guide shroud 14 is blocked, reducing the possibility of external impurities entering the box 1 due to harsh external environments.
