Description

Technical Field

[0001] This application relates to the field of power equipment technology, and in particular to an intelligent meter box. Background Technology

[0002] In the field of power equipment technology, meter boxes are a crucial component for ensuring the safe and stable operation of power systems. With the continuous development and widespread adoption of power systems, the functional and performance requirements for meter boxes are also increasing. Meter boxes must not only possess reliable protective capabilities to ensure that meters and other equipment are protected from external environmental influences, but also meet the flexible combination and heat dissipation needs of different application scenarios to improve the operational efficiency and safety of the power system.

[0003] Prior to this technical solution, various methods were conventionally used to address the issues of splicing and heat dissipation in meter boxes. For splicing, a common practice was to directly fix multiple meter boxes together using bolts and other connectors. While this method achieves basic splicing functionality, it is cumbersome to install and disassemble, requiring specialized tools, and the bolts are prone to rust, affecting the stability and reliability of the splicing. Alternatively, welding was used for splicing, but the welding process can damage the meter box structure, and subsequent adjustments and maintenance are difficult.

[0004] These conventional methods in existing technologies have significant drawbacks. Regarding assembly, the use of bolts or welding makes the assembly of meter boxes inflexible, hindering rapid adjustment and combination according to the actual working environment, thus increasing the difficulty and cost of installation and maintenance. Furthermore, problems such as bolt rust and welding damage can affect the service life and stability of the meter box. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide an intelligent meter box.

[0006] An intelligent meter box includes several boxes, with several connection ports on the side walls of both sides of the boxes, and a fixing plate is provided on the inner wall of the box at the connection port.

[0007] The mounting plate integrates splicing components and heat dissipation components;

[0008] The splicing components include:

[0009] The first plug-in block is set on a fixed plate on one side of the box body. The first plug-in block is slidably connected to the fixed plate, and a first permanent magnet is embedded inside it.

[0010] The second plug-in block is set on the fixed plate on the other side of the box. The second plug-in block is slidably connected to the fixed plate and has a splicing groove inside. A second permanent magnet is set at the bottom of the splicing groove.

[0011] The heat dissipation components include:

[0012] The support frame is connected to the fixed plate via a rotating shaft, and a cooling fan is installed inside the support frame;

[0013] The rotating shaft is rotatably connected to the fixed plate, allowing the support frame to have both a stowed state and a working state.

[0014] By adopting the above technical solution, several boxes can be flexibly assembled into a meter box that adapts to the working environment through splicing components. During splicing, the first permanent magnet and the second permanent magnet attract each other, causing the first plug-in block to be spliced ​​with the second plug-in block. The support frame of the heat dissipation component can rotate and has two states: storage and operation. When in operation, the cooling fan can provide forced air cooling for the inside of the meter box, thereby improving the service life of the meter box.

[0015] Optionally, a sliding groove is provided on the fixed plate, and a third permanent magnet is provided on the inner wall of the sliding groove to which the first plug block is connected; a fourth permanent magnet is provided on the surface of the second plug block, and the fourth permanent magnet and the third permanent magnet attract each other.

[0016] By adopting the above technical solution, when two adjacent boxes are combined, the third permanent magnet and the fourth permanent magnet on the fixing plate attract each other, which allows the second plug block to slide toward the first plug block, making it easier for the first permanent magnet and the second permanent magnet to attract each other, thereby allowing the first plug block to extend into the splicing groove, realizing the splicing of the first plug block and the second plug block, and completing the connection of adjacent boxes.

[0017] Optionally, the first plug-in block has a first fixing hole, and the second plug-in block has a second fixing hole; the fixing plate has a groove, and when the two boxes are spliced, the groove and the groove of the adjacent box form a third fixing hole; the first fixing hole, the second fixing block, and the third fixing hole are coaxially connected and allow fixing screws to pass through, and the screws are threaded to the inner walls of the first fixing hole, the second fixing block, and the third fixing hole.

[0018] By adopting the above technical solution, several boxes are spliced ​​together through the connection port. The first plug-in block and the second plug-in block on the fixing plate are spliced ​​together by the mutual attraction of the first permanent magnet and the second permanent magnet. At the same time, the first fixing hole, the second fixing hole and the third fixing hole formed by the groove are coaxially connected and fixed screws are inserted, which can improve the stability of the splicing and combination of two adjacent boxes.

[0019] Optionally, the support frame abuts against the fixing plate when it is in the retracted state, and the fixing plate is embedded with a photosensitive sensor at the abutment point; the photosensitive sensor is electrically connected to the cooling fan and is used to turn on the power of the cooling fan when the support frame is disengaged from the abutment.

[0020] By adopting the above technical solution, the support frame abuts against the fixed plate when it is stored. The photosensitive sensor at the abutment point connects the power supply of the cooling fan when the support frame is disengaged, which can realize the automatic start of the cooling fan.

[0021] Optionally, a temperature sensor is installed inside the enclosure, which is electrically connected to the cooling fan. The cooling fan is activated when the detected temperature reaches a threshold.

[0022] By adopting the above technical solution, the temperature sensor monitors the temperature inside the box in real time. When the temperature reaches the threshold, the cooling fan is activated to dissipate heat and cool the inside of the box in a timely manner, avoiding the impact of excessive temperature on the normal operation of the meter box and improving the service life of the meter box.

[0023] Optionally, the support frame surface is provided with a snap-fit ​​component for snapping with the side wall of the housing at the connection port after rotation; the support frame is provided with a rubber dustproof block, which abuts and seals against the splicing groove or abuts against the surface of the first plug-in block when the support frame is rotated to the working state.

[0024] By adopting the above technical solution, the rubber dustproof block on the support frame can abut against the splicing groove or abut against the surface of the first plug-in block when the support frame rotates to the working state, so as to avoid contamination of the permanent magnet. At the same time, the cooling fan and the dustproof block can seal the connection port.

[0025] Optionally, a rotating motor is installed inside the housing, and the output rod of the rotating motor is connected to the rotating shaft; a tension sensor is installed inside the fixed plate, and the tension sensor is connected to the first or second plug-in block through a spring; when one plug-in block slides and triggers the tension sensor, the tension sensor drives the rotating motor on the other side to start, so that the support frame located on the same side rotates to the working state.

[0026] By adopting the above technical solution, a rotating motor is connected to a rotating shaft, and a tension sensor is connected to a plug-in block via a spring. When the plug-in block on one side slides and triggers the tension sensor, the tension sensor drives the rotating motor on the other side to start, changing the support frame on the same side from the storage state to the working state. This facilitates the automatic switching of the support frame's working state. The boxes can also be spliced ​​through several connection ports on both sides of the box. The splicing is completed by the magnetic attraction of the first and second plug-in blocks of the splicing component and the permanent magnet. The cooling fan of the heat dissipation component dissipates heat from the inside of the box, and the support frame can switch between the storage and working states.

[0027] Optionally, a dust filter is provided on the cooling fan.

[0028] By adopting the above technical solution, dust can be prevented from entering the meter box by installing a dust filter on the cooling fan.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The splicing component can flexibly connect two adjacent boxes in a detachable manner through the splicing of the first plug-in block and the second plug-in block and the attraction of the permanent magnet, forming an electric meter box that is adapted to the working environment, which solves the problems of inflexibility, cumbersome installation and disassembly and poor stability of traditional splicing methods;

[0031] 2. The cooling fan of the heat dissipation component works with the dustproof block to seal the connection port and provide forced air cooling to the inside of the meter box. At the same time, the dustproof block can seal the splicing groove to avoid contamination of the permanent magnet, thus solving the problems of low efficiency and inflexible adjustment of traditional heat dissipation methods.

[0032] 3. The photosensitive sensor and temperature sensor can control the start of the cooling fan according to the status of the support frame and the temperature inside the box, realizing intelligent heat dissipation and further improving the heat dissipation effect and service life of the meter box.

Two connection ports 3 are located on each side wall of the enclosure 1. A fixing plate 4 is fixedly connected to the inner wall of the enclosure 1 near the connection port 3. The fixing plate 4 integrates a splicing assembly 5 and a heat dissipation assembly 6. The splicing assembly 5 is used to detachably connect two adjacent enclosures 1, thus flexibly forming a meter box adaptable to the working environment. The heat dissipation assembly 6 is used to seal the connection ports 3 on the outside of the meter box and provide forced air cooling to the inside of the meter box, thereby improving the service life of the meter box. The enclosures 1 can be injection molded from any of the following: PC+ABS, PC+ASA gold-containing plastic, or PP+LGF (long glass fiber reinforced polypropylene); or molded from high-performance SMC composite material / machined and welded from stainless steel.

[0043] Reference Figure 3 , Figure 4 , Figure 5The housing 1 has a first sliding groove 7 on the fixing plate 4 of the connection port 3 on one side. The splicing component 5 includes a first plug block 501 slidably connected in the first sliding groove 7. A first permanent magnet 502 is embedded in the first plug block 501 on the side facing the corresponding connection port 3. At the same time, the surface of the first permanent magnet 502 is sealed with epoxy resin, and the sealed epoxy resin block is flush with the surface of the first plug block 501. The epoxy resin provides protection for the first permanent magnet 502 to increase its service life. A first limiting groove 9 is provided on the side wall of the first sliding groove 7. First limiting blocks 503 are fixedly connected to both sides of the first plug block 501. The first limiting blocks 503 extend into the first limiting groove 9 and slide along its inner wall.

[0044] A third permanent magnet 504 is embedded in the side wall of the first sliding groove 7, and the surface of the third permanent magnet 504 is sealed with epoxy resin. The surface of the third permanent magnet 504 is flush with the fixing plate 4 where the first insertion block 501 is located. In addition, a first buffer spring 505 is fixedly connected to the bottom of the first sliding groove 7, and one end of the first buffer spring 505 is fixedly connected to the first insertion block 501, thereby improving the vibration resistance of the first insertion block 501.

[0045] A second sliding groove 8 is provided on the fixing plate 4 of the connection port 3 on the other side of the housing 1, and a second limiting groove 10 is provided on the side wall of the second sliding groove 8. In addition, a second buffer spring 510 is fixedly connected to the bottom of the second sliding groove 8, and a second plug-in block 506 is fixedly connected to one end of the second buffer spring 510. A second limiting block 507 is fixedly connected to both sides of the second plug-in block 506. The second limiting block 507 extends into the second limiting groove 10 and slides along its inner wall. A splicing groove 11 is provided on the side of the second plug-in block 506 near the corresponding connection port 3, and a second permanent magnet 508 is fixedly connected to the bottom of the splicing groove 11. The surface of the second permanent magnet 508 is sealed with epoxy resin. At the same time, a fourth permanent magnet 509 is embedded on the surface of the second plug-in block 506 near the connection port 3. The fourth permanent magnet 509 is sealed with epoxy resin, and the surface of the fourth permanent magnet 509 is flush with the surface of the second plug-in block 506.

[0046] After two adjacent boxes 1 are combined, the connection ports 3 of the two adjacent boxes 1 are aligned and used for wire passage. At the same time, the fixing plates 4 on the two boxes 1 are aligned, so that the third permanent magnet 504 of one box 1 and the fourth permanent magnet 509 of the other box 1 attract each other, thereby causing the second plug block 506 to slide toward the first plug block 501 and the third permanent magnet 504 and the fourth permanent magnet 509 to abut. At the same time, the first permanent magnet 502 and the second permanent magnet 508 attract each other, causing the first plug block 501 to extend into the splicing groove 11, thereby splicing the first plug block 501 and the second plug block 506 together.

[0047] Reference Figure 5 , Figure 6 The first plug-in block 501 has a first fixing hole 12 on its side, and the second plug-in block 506 has a second fixing hole 13 on its side. Furthermore, the fixing plate 4 has a groove 14 on its side near the corresponding connection port 3. After the two boxes 1 are assembled, the grooves 14 on the fixing plates 4 of the two adjacent boxes 1 are aligned to form a third fixing hole. After the two adjacent boxes 1 are assembled, the first fixing hole 12, the second fixing hole 13, and the third fixing hole are coaxially connected. Screws 15 are inserted into the first fixing hole 12, the second fixing hole 13, and the third fixing hole, respectively, and are threaded to the inner walls of the first fixing hole 12, the second fixing hole 13, and the third fixing hole, thereby improving the stability of the assembled two adjacent boxes 1.

[0048] Reference Figure 2 , Figure 3 , Figure 4 The heat dissipation assembly 6 includes two connecting plates 601 fixedly connected to the fixing plate 4. The two connecting plates 601 are close to the connection port 3 and are respectively disposed on both sides of the first sliding groove 7 or the second sliding groove 8 in the vertical direction. A rotating shaft 602 is rotatably connected to the two connecting plates 601. A gap is provided between the rotating shaft 602 and the first plug-in block 501 or the second plug-in block 506 to avoid friction between the first plug-in block 501 or the second plug-in block 506 and the rotating shaft 602.

[0049] Reference Figure 4 , Figure 7 A support frame 603 is fixedly connected to the rotating shaft 602. A cooling fan 605 is fixedly connected to one side of the support frame 603, and a dustproof mesh 607 is fixedly connected to the surface of the cooling fan 605. A rubber dustproof block 604 is fixedly connected to the other side of the support frame 603. Additionally, the support frame 603 has a movable groove 23, within which a movable spring 608 is fixedly connected. The dustproof block 604 is slidably connected within the movable groove 23, and the movable spring 608 is fixedly connected to the dustproof block 604. After the two housings 1 are assembled, the two dustproof blocks 604 abut against each other, slide into the movable groove 23, and cause the movable spring 608 to deform and compress.

[0050] Reference Figure 2 , Figure 3 , Figure 4The support frame 603 can rotate along the rotation axis 602, allowing it to have both a stowed and a working state. The vertical surfaces of the support frame 603 are fixedly connected to locking protrusions 606, and the inner wall of the housing 1 at the connection port 3 is fixedly connected to a locking groove 16. When the support frame 603 is in the working state, rotating along the rotation axis 602, the locking protrusions 606 abut against the inner wall of the locking groove 16, thereby securing the support frame 603 to the housing 1. Furthermore, when the support frame 603 is in the working state, the cooling fan 605 and the dustproof block 604 cooperate to seal the connection port 3, and the dustproof mesh 607 of the cooling fan 605 faces outwards.

[0051] refer to Figure 4 , Figure 5 , Figure 6 The dustproof block 604 abuts against the side of the first plug-in block 501 or the second plug-in block 506 facing the connection port 3. The dustproof block 604 can seal the splicing groove 11 to prevent contamination of the permanent magnet. In addition, the dustproof block 604 has a relief groove 17 corresponding to the position of the groove 14 on the fixing plate 4. After two adjacent boxes 1 are spliced, the relief grooves 17 of the dustproof blocks 604 on the two boxes 1 cooperate to form a relief hole, and the relief hole is coaxially arranged with the first fixing hole 12.

[0052] Reference Figure 3 , Figure 4 , Figure 7 In its retracted state, the support frame 603 abuts against the fixed plate 4, and a photosensitive sensor 18 is installed at the abutment point. The photosensitive sensor 18 is fixedly connected to the fixed plate 4. Simultaneously, a battery 19 is fixedly connected inside the housing 1, and the battery 19 is electrically connected to the photosensitive sensor 18 and the cooling fan 605. When the support frame 603 changes from its retracted state to its operating state, the support frame 603 and the photosensitive sensor 18 disengage, allowing the photosensitive sensor 18 to receive light, thereby controlling the battery 19 to output current to the cooling fan 605. Additionally, a temperature sensor 20 is fixedly connected inside the housing 1, used to monitor temperature changes inside the housing 1 in real time. When the temperature inside the housing exceeds 40°C, the temperature sensor 20 transmits an electrical signal to the cooling fan 605 to control the cooling fan 605 to start, thereby cooling the interior of the housing 1. It should be noted that when one support frame 603 is in the retracted state and the other support frame 603 is in the working state, when the photosensitive sensor 18 in the working state is triggered, the cooling fan 605 of the support frame 603 in the working state and the cooling fan 605 of the support frame 603 in the retracted state are simultaneously powered on.

[0053] Reference Figure 3 , Figure 4A rotating motor 21, which is electrically connected to the battery 19, is fixedly connected to the inner wall of the housing 1, and the output rod of the rotating motor 21 is fixedly connected to the rotating shaft 602. In addition, a tension sensor 22 is fixedly connected to both the first sliding groove 7 and the second sliding groove 8 of the fixing plate 4, and the tension sensor 22 is fixedly connected to the first buffer spring 505 and the second buffer spring 510 corresponding to the position.

[0054] If two adjacent boxes 1 are spliced ​​together, when the first buffer spring 505 or the second buffer spring 510 triggers the tension sensor 22 on one of the fixed plates 4, the tension sensor 22 can drive the drive motor located close to the fixed plate 4 on the side where the tension sensor 22 is not triggered to rotate, and cause the support frame 603 on that side to change from the storage state to the working state; if two adjacent boxes 1 are spliced ​​together, and the tension sensors 22 on both fixed plates 4 are triggered, the tension sensors 22 can drive the rotation motor 21 and control the support frame 603 to rotate in the storage state; if the support frame 603 is in the storage state, the drive motor stops running.

[0055] The implementation principle of this application embodiment is as follows: When assembling the meter box, the operator aligns the connection ports 3 of adjacent boxes 1. At this time, the third permanent magnet 504 and the fourth permanent magnet 509 on the two side fixing plates 4 first generate magnetic attraction, driving the second plug-in block 506 to slide towards the first plug-in block 501 (overcoming the resistance of the buffer spring), so that the first permanent magnet 502 and the second permanent magnet 508 in the second plug-in block 506 enter the effective range of action. Under the synergistic action of the dual magnetic attraction (first / second permanent magnet 508, third / fourth permanent magnet 509), the first plug-in block 501 automatically embeds into the splicing groove 11 to complete the pre-positioning. Subsequently, mechanical locking is achieved by the screw 15 passing through the third fixing hole formed by the first fixing hole 12, the second fixing hole 13 and the groove 14, realizing the dual goals of rapid splicing and high stability.

[0056] In addition, the heat dissipation system is intelligently activated through a dual mechanism. When the internal temperature exceeds the threshold (40℃), the temperature sensor 20 directly starts the cooling fan 605. At the same time, when the support frame 603 changes from the stored state to the working state, it disengages from the fixing plate 4, and the photosensitive sensor 18 senses the change in light and automatically turns on the fan power. At this time, the support frame 603 is locked in position by the snap-fit ​​component, and its surface dustproof block 604 simultaneously provides double protection, used to seal the splicing groove 11 to prevent permanent magnet contamination, and at the same time, it works with the dustproof mesh 607 to seal the connection port 3.

[0057] When the plug-in block slides and triggers the tension sensor 22 (such as during splicing operation), the system automatically drives the same-side rotating motor 21 to switch the storage-state support frame 603 to the working state; if both sides of the tension sensor 22 are triggered (one box 1 is spliced ​​to both sides of another box 1), the support frame 603 is controlled to return to the storage state to provide a channel for the wires connected inside the box 1.

[0058] This solution achieves the core effects of convenient installation, intelligent heat dissipation, and long-term stable operation through the synergy of five technologies: magnetic guide splicing, mechanical reinforcement, temperature control / displacement dual-mode heat dissipation triggering, dynamic dustproof sealing, and electromechanical linkage control.

[0059] In addition, the enclosure 1 is made of PC+ABS / SMC composite material by compression molding, which has insulation, corrosion resistance and high mechanical strength; the cooling fan 605 in the heat dissipation component 6 is equipped with copper heat sink and aluminum back plate, and the heat conduction efficiency is improved by filling the gap with thermally conductive silicone, and low-maintenance heat dissipation is achieved in conjunction with the dust filter 607 and the detachable structure.

[0060] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
