Description

Technical Field

[0001] This invention relates to the field of meter box technology, and more specifically, to a plug-in protected meter box. Background Technology

[0002] As an important device for housing and protecting electricity meters and related electrical equipment, the main function of the meter box is to ensure the safe operation of the meter, prevent external interference, and avoid electrical accidents. Existing meter boxes are typically made of metal or plastic, possessing certain waterproof, dustproof, and corrosion-resistant properties, which can meet the requirements of conventional electricity metering and management. To improve the safety and stability of the meter box, traditional designs often include pluggable terminals, protective switches, and safety locks to facilitate the installation, maintenance, and repair of the meter.

[0003] In outdoor electricity metering scenarios (such as centralized metering points in residential areas, open-air power distribution areas in industrial parks, and metering positions next to utility poles in rural areas), meter boxes need to withstand the complex environmental effects of wind, rain, dust accumulation, and temperature fluctuations for a long time. Their requirements for protection performance, ease of operation and maintenance, and equipment stability are far higher than those for indoor meter boxes.

[0004] Existing outdoor meter boxes typically use thickened metal shells or waterproof plastic materials, which meet basic rain and dust protection requirements. Some are even equipped with pluggable terminals and mechanical safety locks to optimize installation and maintenance. However, in practical applications, three core pain points remain, making them unsuitable for the stringent demands of outdoor environments: For example, the installation and removal of traditional meters usually rely on bolts, which is not only cumbersome but also increases the workload of maintenance personnel, especially when meters need frequent replacement or repair. Furthermore, the cooling systems and filters of traditional meter boxes often suffer from air leaks and blockages, resulting in poor heat dissipation and excessively high temperatures, potentially affecting meter accuracy or even damaging the equipment. Finally, the lack of effective debris collection devices allows dust and debris to accumulate, leading to risks such as equipment malfunctions and short circuits.

[0005] Based on this, the present invention designs a pluggable protective meter box to solve the above problems. Summary of the Invention

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide a pluggable protective meter box to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

The fan drive is fixedly connected to the outside of the mounting brackets. The output end of the fan drive is fixedly connected to the inside of the inner ring of the one-way bearing. The fan blades are fixedly connected to the outside of the outer ring of the one-way bearing.

[0013] Preferably, a connecting rod is fixedly connected to the outside of the inner ring of the one-way bearing, a rotating shaft is fixedly connected to the end of the connecting rod away from the one-way bearing, and a scraper is fixedly connected to the end of the rotating shaft away from the connecting rod.

[0014] Preferably, the scraper abuts against the filter screen on the side near the rotating shaft, and the filter screen is fixedly connected inside the mounting frame.

[0015] Preferably, each of the mounting frames has a material feeding groove inside, and both sides of the bottom of the mounting frame are fixedly connected to a fixing limiting member.

[0016] Preferably, the collecting assembly includes a fixed limiting member, a movable limiting member, a limiting cavity, a pressing plate, a second spring, a sliding plate, and a collecting box. The collecting box is located at the bottom of the mounting frame. Each collecting box has a limiting cavity inside. A second spring is fixedly connected inside the limiting cavity.

[0017] Preferably, a sliding plate is fixedly connected to the bottom of each of the movable limiting members, the outside of the sliding plate is slidably connected to the inside of the collection box, and a pressing plate is fixedly connected to the side of the sliding plate away from the collection box.

[0018] Preferably, an electricity meter is fixedly connected to the end of the plug that is away from the fixing rod.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of this invention are:

[0021] 1) In this invention, a plug-in assembly consisting of a mounting block, a plug-in block, a limiting rod, and a spring is designed to achieve convenient disassembly and reliable fixing of the electricity meter. During installation, simply insert the plug-in block connected to the electricity meter into the slot of the mounting block. The plug-in block drives the fixing rod and the limiting plate to insert, and the spring in the limiting slot pushes the limiting rod to automatically engage with the corresponding side of the limiting plate, completing the rapid positioning of the electricity meter. When disassembly is required, pressing the electricity meter or pulling the sliding rod upwards will cause the limiting rod to compress the spring and disengage, allowing the plug-in block and electricity meter to be directly removed. When the electricity meter is pressed, the plug-in block moves the fixing rod and the limiting plate inwards into the mounting block. At this time, the limiting rod pushes the sliding block to one side of the limiting plate, allowing the limiting rod to disengage from the limiting plate. Compared to traditional bolt fixing methods, this eliminates the need for repeated screw tightening with tools, significantly shortening the time for electricity meter installation, maintenance, or replacement, and reducing the operational intensity of maintenance personnel.

[0022] 2) In this invention, the heat dissipation component adopts a linked design of fan drive, one-way bearing, and scraper, which achieves efficient heat dissipation while automatically cleaning the filter. When the fan drive is working, its output end drives the outer ring of the fan blades to rotate through the one-way bearing, forming air convection inside and outside the box, quickly removing the heat generated by the meter operation, and avoiding metering errors or component damage due to high temperature. At the same time, the inner ring of the one-way bearing synchronously drives the connecting rod, rotating shaft, and scraper to rotate. The scraper continuously abuts against the surface of the filter, scraping away the dust and debris attached to the filter. When heat dissipation is not required and the filter needs to be cleaned, the output end of the reverse drive motor drives the inner ring of the one-way bearing and the scraper to rotate and clean, and the material falls into the collection component below through the discharge chute of the mounting frame. This design solves the problem of easy clogging of filter screens in traditional meter boxes and the need for regular manual cleaning, ensuring that the heat dissipation channel is unobstructed for a long time and reducing the risk of equipment failure caused by filter clogging.

[0023] 3) In this invention, the collection component, through the cooperation of a fixed limiting component, a movable limiting component, a second spring, and a pressing plate, achieves quick assembly and disassembly of the collection box and its secure fixation. During installation, simply align the collection box with the bottom of the mounting frame. The movable limiting component is compressed by the fixed limiting component, thus compressing the second spring. Once the collection box is in place, the second spring resets, pushing the movable limiting component to engage with the fixed limiting component, completing the fixation. When cleaning is complete, simply press the pressing plates on both sides. The sliding plate will cause the movable limiting component to compress the second spring, disengaging it from the fixed limiting component, allowing the collection box to be removed directly to empty the debris. The entire process requires no tools, is simple to operate, and facilitates regular cleaning of collected dust and debris by maintenance personnel, preventing debris accumulation from affecting heat dissipation or falling into the meter box and causing a short circuit risk.

[0024] 4) In summary, this invention enhances the overall protection and practicality of the meter box through multiple structural designs: the front door effectively isolates the box from external rainwater, dust, and unauthorized personnel, while the top front baffle further prevents rainwater from seeping in through the door gaps; the mounting holes at the four rear corners facilitate the overall installation and fixation of the meter box, and the mounting plate design provides a stable installation base for the plug-in components; simultaneously, the limiting structure of the plug-in components, the filter protection of the heat dissipation components, and the debris collection components together construct a multi-layered protection system that prevents accidental touches, blockages, high temperatures, and debris. In conclusion, this invention improves the efficiency of meter maintenance and ensures stable equipment operation while also considering ease of operation and safety, making it suitable for various outdoor or indoor meter installation scenarios.

Front edge baffle. Detailed Implementation

[0036] Example: Please refer to Figure 1-10A plug-in protective meter box includes a meter box 1. A door 7 is hinged to the front of the meter box 1. A front edge baffle 11 is provided on the top of the meter box 1. Mounting holes 4 are provided at the four corners of the rear side of the meter box 1. Fixing nails 2 are fixedly connected to the four corners inside the meter box 1. Mounting plates 3 are provided outside the fixing nails 2. Plug-in components 5 are fixedly connected to the front of the mounting plates 3. Heat dissipation components 8 are fixedly installed on both sides of the meter box 1. A collection component 10 is provided at the bottom of the heat dissipation components 8. The plug-in components 5 include mounting blocks 501, plug blocks 502, fixing rods 503, limiting plates 504, sliding blocks 505, sliding rods 506, springs 507, limiting rods 508, limiting grooves 509, and slots 5010. Mounting blocks 501 are all fixedly connected to the outside of the mounting plates 3. The mounting block 501 has a slot 5010 inside, and a plug block 502 is set inside the slot 5010. A fixing rod 503 is fixedly connected to the outer wall of the plug block 502. A limiting plate 504 is fixedly connected to the end of the fixing rod 503 away from the plug block 502. A sliding block 505 is slidably connected to the outside of the fixing rod 503. Each mounting block 501 has a limiting groove 509 inside. A spring 507 is fixedly connected to the top of each limiting groove 509. A limiting rod 508 is fixedly connected to the bottom of each spring 507. The limiting rod 508 is slidably connected inside the limiting groove 509. A sliding rod 506 is fixedly connected to the top of each limiting rod 508. The outside of the sliding rod 506 is slidably connected inside the mounting block 501. A meter 6 is fixedly connected to the end of the plug block 502 away from the fixing rod 503.

[0037] The front door 7 of the meter box 1 is connected by a hinge. When closed, it can prevent rainwater and dust from entering the box and prevent unauthorized personnel from accidentally touching the meter or components. The front edge baffle 11 on the top extends outward to prevent rainwater from seeping into the gap between the door 7 and the meter box 1. This is especially suitable for outdoor installations and reduces the corrosion of internal components by rainwater. The mounting holes 4 at the four corners of the rear side of the meter box 1 make it easy to fix the meter box to the wall or bracket with bolts to prevent the meter box from tipping over. The fixing nails 2 at the four corners inside are used to fix the mounting plate 3. The mounting plate 3 provides a stable mounting base for the plug-in components 5, ensuring that the plug-in components will not shift during the installation and removal of the meter and improving the overall structural stability.

[0038] Fixing the plug-in assembly 5: Fix the mounting block 501 symmetrically to the preset position on the front side of the mounting plate 3 with screws, ensuring that the opening of the slot 5010 of the mounting block 501 faces the side of the box door 7 (to facilitate the subsequent insertion of the electricity meter). Then, complete the assembly of the internal limiting structure of the mounting block 501 in sequence: fix the spring 507 at the top inside the limiting groove 509, and weld (or snap) the limiting rod 508 to the bottom of the spring 507, ensuring that the limiting rod 508 can slide up and down along the limiting groove 509; fix one end of the slide rod 506 to the top of the limiting rod 508, and let the other end pass through the side wall of the mounting block 501 and retain a certain operating length to form a "slide rod-limiting rod" linkage structure.

[0039] Connecting the meter 6 to the plug-in component: Fix one end of the plug 502 to the back of the meter 6 with bolts (or welding) to ensure a firm connection; weld a fixing rod 503 to the other end of the plug 502, and weld a limiting plate 504 to the end of the fixing rod 503 away from the plug 502 (the size of the limiting plate 504 must be compatible with the slot 5010, and a limiting notch for matching the limiting rod 508 must be reserved); finally, insert the sliding block 505 along the axial direction of the fixing rod 503 to ensure that the sliding block 505 can slide freely along the fixing rod 503, thus completing the integrated assembly of the meter and the plug-in component.

[0040] Final fixing of meter 6: Hold meter 6 and align the insert 502 on its back with the slot 5010 of mounting block 501. Slowly push it in until the limiting plate 504 contacts the bottom of slot 5010. At this time, the spring 507 in the limiting groove 509 releases its elasticity, pushing the limiting rod 508 downward and locking it into the limiting notch of the limiting plate 504, thus achieving automatic locking of meter 6. After gently pulling meter 6 to confirm that it is not loose, the meter installation is complete without the need for additional tools.

[0041] Reference Figure 7 , Figure 8 and Figure 10The heat dissipation assembly 8 includes a mounting frame 801, a mounting bracket 802, a fan drive 803, a fan blade 804, a one-way bearing 805, a filter screen 806, a connecting rod 807, a scraper 808, and a rotating shaft 809. The mounting frames 801 are fixedly installed inside both sides of the meter box 1. The mounting brackets 802 are fixedly connected inside each mounting frame 801. The fan drive 803 is fixedly connected to the outside of the mounting brackets 802. The output end of the fan drive 803 is fixedly connected to the inner ring of the one-way bearing 805, and the outer ring of the one-way bearing 805 is fixedly connected to... A fan blade 804 is attached. A connecting rod 807 is fixedly connected to the outer side of the inner ring of a one-way bearing 805. A rotating shaft 809 is fixedly connected to the end of the connecting rod 807 away from the one-way bearing 805. A scraper 808 is fixedly connected to the end of the rotating shaft 809 away from the connecting rod 807. The side of the scraper 808 near the rotating shaft 809 abuts against a filter screen 806. The filter screen 806 is fixedly connected inside the mounting frame 801. A material discharge groove 9 is provided inside the mounting frame 801. Fixed limiting members 1001 are fixedly connected to both sides of the bottom of the mounting frame 801.

[0042] Mounting frame 801 and filter 806 are fixed together: Mounting frame 801 is embedded into the preset openings on both sides of the meter box 1 with screws to ensure that mounting frame 801 is sealed and fitted to the side wall of the box (a sealing strip can be added to prevent rainwater from seeping in); the filter 806 is fixed to the outer port of mounting frame 801 (facing the outside of the box) with a buckle. The filter 806 must completely cover the opening of mounting frame 801 to filter dust and debris in the outside air.

[0043] Fan drive and one-way bearing assembly: Weld (or screw) the mounting bracket 802 to the center of the mounting frame 801. Then, fix the fan drive 803 (a small axial flow fan can be selected) to the mounting bracket 802 with bolts, ensuring that the output shaft of the fan drive 803 faces the inside of the mounting frame 801 (towards the inside of the housing). Fix the inner ring of the one-way bearing 805 to the output shaft of the fan drive 803 by key connection (or tight fit), ensuring that the inner ring of the one-way bearing rotates synchronously with the output shaft. Evenly weld 3-4 fan blades 804 onto the outer ring of the one-way bearing 805. The angle of the fan blades 804 needs to be designed according to the "outward exhaust" requirement (clockwise rotation generates outward airflow).

[0044] Scraper and connecting rod assembly: A connecting rod 807 is welded to the outer side of the inner ring of the one-way bearing 805 (the end away from the fan drive 803). The end of the connecting rod 807 away from the one-way bearing is connected to the scraper 808 via a rotating shaft 809. Adjust the angle of the scraper 808 so that the side closest to the rotating shaft is in close contact with the surface of the filter screen 806 (the contact pressure should be moderate to avoid scratching the filter screen). Finally, a discharge groove 9 is opened at the bottom of the mounting frame 801 (the discharge groove 9 must be located directly below the filter screen 806) to ensure that the impurities scraped off by the scraper 808 can fall downward through the discharge groove 9.

[0045] Circuit connection: Connect the power cord of the fan drive 803 to the power supply inside the meter box 1 through the wiring channel (a temperature controller can be connected in series to achieve "automatic start at high temperature and automatic shutdown at low temperature") to complete the circuit assembly of the heat dissipation components and ensure that the fan drive can rotate normally in both directions.

[0046] Reference Figure 1 , Figure 7 and Figure 9 The collection assembly 10 includes a fixed limiting member 1001, a movable limiting member 1002, a limiting cavity 1003, a pressing plate 1004, a second spring 1005, a sliding plate 1006, and a collection box 1007. The collection box 1007 is located at the bottom of the mounting frame 801. Each collection box 1007 has a limiting cavity 1003 inside. A second spring 1005 is fixedly connected inside the limiting cavity 1003. The other end of each second spring 1005 is fixedly connected to a movable limiting member 1002. The outside of the movable limiting member 1002 abuts against the outside of the fixed limiting member 1001. A sliding plate 1006 is fixedly connected to the bottom of each movable limiting member 1002. The outside of the sliding plate 1006 is slidably connected inside the collection box 1007. A pressing plate 1004 is fixedly connected to the side of the sliding plate 1006 away from the collection box 1007.

[0047] Fixed limiting component preset: Fixed limiting components 1001 are welded to both sides of the bottom of the mounting frame 801 (located on both sides of the feeding groove 9). The outer side of the fixed limiting component 1001 needs to be designed with a sloping structure (to facilitate the subsequent engagement of the moving limiting component), and a slot is reserved to cooperate with the moving limiting component 1002.

[0048] Assembly of the internal structure of the collection box: Limiting cavities 1003 are respectively opened inside the two side walls of the collection box 1007. A second spring 1005 is fixed to the bottom inner side of the limiting cavity 1003. A movable limiting member 1002 is welded to the other end of the second spring 1005. A protrusion adapted to the slot of the fixed limiting member 1001 is designed on the outer side of the movable limiting member 1002. One end of the sliding plate 1006 is welded to the bottom of the movable limiting member 1002, and the other end protrudes through the bottom side wall of the collection box 1007. A pressing plate 1004 is welded to the protruding end to ensure that when the pressing plate 1004 is pressed, it can drive the sliding plate 1006 and the movable limiting member 1002 to move synchronously into the limiting cavity 1003, compressing the second spring 1005.

[0049] Installation of collection box 1007: Align the assembled collection box 1007 with the fixed limiting member 1001 at the bottom of the mounting frame 801, and push the collection box 1007 upward. At this time, the movable limiting member 1002 is squeezed by the inclined surface of the fixed limiting member 1001, moves into the limiting cavity 1003 and compresses the second spring 1005. When the collection box 1007 moves to the preset position (the feeding groove 9 is completely above the collection box), the movable limiting member 1002 is aligned with the slot of the fixed limiting member 1001, the second spring 1005 resets and pushes the movable limiting member 1002 outward to be inserted into the slot of the fixed limiting member, thus completing the fixation of the collection box and ensuring that the collection box will not fall off due to gravity.

[0050] Working principle of this invention:

[0051] Meter 6 Installation and Fixing: First, pre-connect the meter 6 to the plug 502. During installation, simply align the plug 502 with the slot 5010 of the mounting block 501 and push it inward. The plug 502 drives the fixing rod 503 and the limiting plate 504 at the end to extend into the slot 5010 simultaneously. When the limiting plate 504 moves below the limiting rod 508, the compressed spring 507 in the limiting groove 509 releases its elasticity, pushing the limiting rod 508 downward and locking it into the corresponding limiting position of the limiting plate 504. At this time, the plug 502 is locked by the limiting rod 508 and cannot be arbitrarily removed, thus completing the quick fixing and positioning of the meter and ensuring that the meter will not be displaced due to vibration or accidental contact during operation.

[0052] Meter 6 Disassembly and Unlocking: The disassembly process offers two convenient operation modes to adapt to different maintenance scenarios:

[0053] Pulling the slide bar 506 to unlock: When it is necessary to remove the meter completely, pull the slide bar 506 outside the mounting block 501 upward. The slide bar 506 drives the limiting rod 508 to move upward along the limiting groove 509, compressing the spring 507 and disengaging it from the limiting structure of the limiting plate 504. At this time, the meter 6 can be pulled out directly, which will drive the insert block 502, the fixing rod 503 and the limiting plate 504 to disengage from the slot 5010, completing the disassembly.

[0054] Unlocking by pressing meter 6: If you need to quickly release the meter, press meter 6 towards mounting block 501. The meter will cause insert block 502 and fixing rod 503 to move further inward. Limiting plate 504 will simultaneously squeeze sliding block 505 (sliding block 505 is sleeved on the outside of fixing rod 503). After being squeezed, sliding block 505 will move towards limiting rod 508, pushing limiting rod 508 to compress spring 507 and disengage from limiting plate 504, thus unlocking the meter. Then you can pull out the meter without additional operation of the sliding rod, further simplifying the disassembly process.

[0055] Normal heat dissipation mode: When the temperature inside the meter box 1 rises and heat dissipation is required, the fan drive 803 on the mounting bracket 802 is activated. The output end of the fan drive 803 drives the inner ring of the one-way bearing 805 to rotate clockwise. Since the outer ring and inner ring of the one-way bearing 805 are in a synchronous transmission state in the clockwise direction, the outer ring rotates synchronously with the inner ring and drives the fan blade 804 to rotate. The fan blade 804 forms an airflow inside the mounting frame 801: exhausting the hot air inside the meter box 1 to the outside, while simultaneously drawing in cold air from the outside, forming air convection between the inside and outside of the box, quickly removing the heat generated by the operation of the meter 6 and other components, and preventing the meter's metering accuracy from decreasing or components from burning out due to high temperature.

[0056] At the same time, the inner ring of the one-way bearing 805 synchronously drives the connecting rod 807 to rotate. The connecting rod 807 drives the scraper 808 to rotate along the surface of the filter screen 806 through the rotating shaft 809 (the filter screen 806 is fixed on the outside of the mounting frame 801 and is used to filter dust and impurities in the outside air). The scraper 808 continuously abuts against the surface of the filter screen 806, scraping off the dust, lint and other impurities attached to the filter screen. The scraped impurities fall into the collection component 10 below through the discharge chute 9 at the bottom of the mounting frame 801 under the action of gravity, realizing "automatic cleaning of the filter screen while dissipating heat" and ensuring that the heat dissipation channel is always unobstructed.

[0057] Independent Cleaning Mode: When the temperature inside the meter box 1 is low and heat dissipation is not required, but the filter screen has accumulated a certain amount of impurities, the fan drive 803 is started in reverse, causing its output end to drive the inner ring of the one-way bearing 805 to rotate counterclockwise. At this time, the outer ring and inner ring of the one-way bearing 805 are separated (one-way transmission characteristic), and the outer ring and fan blade 804 remain stationary to avoid unnecessary airflow disturbance; while the inner ring still drives the connecting rod 807, rotating shaft 809 and scraper 808 to rotate, and the scraper 808 continues to scrape off the impurities on the filter screen 806, which fall into the collection assembly through the discharge trough 9, realizing the independent operation mode of "cleaning only without heat dissipation", reducing energy consumption while ensuring the cleanliness of the filter screen.

[0058] Collection box installation and fixing: When installing the collection box 1007, align the collection box 1007 with the fixing limit member 1001 at the bottom of the mounting frame 801 (fixing limit members 1001 are preset on both sides of the bottom of the mounting frame 801), and push the collection box 1007 upward. The movable limit member 1002 in the limiting cavity 1003 inside the collection box 1007 is pressed into the limiting cavity 1003 by the inclined surface of the fixing limit member 1001, compressing the second spring 1005; when the collection box 1007 moves to the preset position, the movable limit member 1002 aligns with the slot of the fixing limit member 1001, and the second spring 1005 releases its elastic force to push the movable limit member 1002 outward, engaging with the slot of the fixing limit member 1001, thus firmly fixing the collection box 1007 to the bottom of the mounting frame 801, ensuring that the collection box will not fall off due to gravity or vibration, and reliably receiving impurities falling from the discharge chute 9.

[0059] Collection box cleaning and disassembly: When impurities accumulate in the collection box 1007 to a certain extent and need to be cleaned, press the pressing plates 1004 on both sides of the collection box 1007 simultaneously by hand. The pressing plates 1004 drive the sliding plate 1006 to move inward along the slide of the collection box 1007. The sliding plate 1006 pushes the moving limit piece 1002 to compress the second spring 1005, disengaging it from the slot of the fixed limit piece 1001 and releasing the lock. At this time, simply pull the collection box 1007 downward to remove it from the bottom of the mounting frame 801. After emptying the internal impurities, reassemble it according to the installation steps for reuse. The whole process requires no tools, is easy to operate, and avoids the risk of short circuit caused by impurities accumulating and clogging the discharge chute or falling into the meter box.
