Description

Technical Field

[0001] The present application relates to the technical field of ring network boxes, and in particular to a quick-disassembly and protective primary and secondary fusion ring network box. Background Art

[0002] In power distribution systems, integrated primary and secondary ring mainframe boxes (RMBs) are critical equipment for ensuring stable grid operation and efficient power distribution. With the growth of urban construction and electricity demand, higher requirements are being placed on the installation convenience and space utilization of RMGs. Against this backdrop, small, compact outdoor RMGs have emerged. With their advantages of small size and ease of outdoor installation, they are well suited to complex urban environments and effectively meet the diverse needs of power distribution and control, making them a key option in current power facility construction.

[0003] A common small, compact outdoor ring network box in the related art consists primarily of a box body and a door mounted on it. In terms of structural design, the rear or side walls of the box are securely fixed with mounting brackets using screws, allowing the electrical components to be neatly inserted. For terminal block installation, a plug-in method is the mainstream method to facilitate subsequent assembly and disassembly, as well as routine maintenance. Specifically, the terminal block features protruding blocks that simply snap into corresponding slots on the mounting bracket for installation, making it simple and efficient.

[0004] However, this seemingly convenient terminal block installation method has significant drawbacks in practice. During transportation, the ring main unit (RMB) is subject to inevitable jolting and vibration from vehicles, and during installation, the hoisting process can easily generate impact forces due to shaking. These conditions can easily cause the terminal block to become loose, and in severe cases, it can even completely separate from the mounting bracket. If the terminal block becomes detached, it can seriously affect the normal operation of the electrical system within the RMU, causing power failures. This leaves room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a quick-disassembly protected primary and secondary fusion ring network box to solve the problem that the terminal block installation may become loose during the transportation or lifting process of the above-mentioned ring network box.

[0006] The present application provides a quick-disassembly protection primary and secondary fusion ring network box adopts the following technical solutions: The lock hole is fixed on the top of the box body, and the locking plate is fixed on the top of the box body, and the locking plate is fixed on the top of the box body to unlock the box body.

[0007] By adopting this technical solution, the terminal block is initially positioned and installed by inserting fixed blocks into the fixed slots of the baseboard, making it easy to operate. The combination of the limit plate, positioning plate, and locking plate, combined with the control components inside the door and the reset components on the baseboard, enables convenient locking and unlocking of the terminal block. When the door is closed, the control components drive the two locking plates to slide toward each other, quickly locking the terminal block and ensuring a secure connection to prevent loosening. When the door is opened, the reset components cause the two locking plates to slide away from each other, automatically unlocking the terminal block for quick disassembly and maintenance. This design improves the stability and reliability of terminal block installation.

[0008] Optionally, the control component includes a control plate fixed on the inner side of the door, and a guide slope is provided on the outer side of the connection between the positioning plate and the locking plate; when the door is closed, the control plate is squeezed against the positioning plate along the guide slope, causing the two locking plates to slide toward each other.

[0009] By adopting this technical solution, when the door is closed, the control panel smoothly applies a squeezing force to the positioning plate along the guide ramp. Due to the guiding properties of the guide ramp, this force is precisely converted into the force that causes the two locking plates to slide toward each other. This allows the terminal block to be quickly and reliably locked to the baseplate without requiring additional complex steps or tools, effectively preventing the terminal block from loosening and ensuring a stable electrical connection.

[0010] Optionally, the upper side and bottom surfaces of the substrate are provided with limiting slots for the limiting plate to be inserted and slided, the limiting plate is fixed with a limiting protrusion, and the side walls of the limiting slot are provided with limiting sliding grooves for the limiting protrusion to be inserted and slided; the reset member is a reset spring located in the limiting slot, and the two ends of the reset spring are respectively in contact with the bottom surface of the limiting slot and the side of the limiting plate away from the positioning plate.

[0011] By adopting the above technical solution, the reset element is designed as a reset spring located in the limit slot, with its two ends respectively contacting the bottom surface of the limit slot and the corresponding side surface of the limit plate. When the box door is opened, the reset spring can automatically and smoothly drive the two limit plates to slide away from each other by virtue of its own elastic potential energy, so that the locking plate unlocks the terminal block, eliminating the need for additional manual reset operation, thereby improving operational convenience and efficiency. At the same time, this design is compact and occupies little space, which is conducive to the rational layout and optimized utilization of the internal space of the ring network box.

[0012] Optionally, a protective cover with an opening facing downward is fixedly provided on the outer edges of the openings of several of the heat dissipation openings, and a guide cover with an opening facing upward is fixedly provided on the inner edges.

[0013] By adopting the above technical solution, a downward-facing protective shield is installed on the outer edge of the heat dissipation opening, effectively preventing rain, dust, and debris from entering the ring network box directly, preventing these foreign objects from damaging the electrical components inside the box, extending the service life of the equipment, reducing the incidence of failures caused by environmental factors, and improving the stability of equipment operation. Furthermore, an upward-facing air deflector is installed on the inner edge of the heat dissipation opening to guide the hot air inside the box to be discharged upward more smoothly, optimizing the air circulation path inside the box, enhancing the heat dissipation effect, and helping to dissipate the heat generated by the electrical components in a timely manner, preventing excessive temperatures inside the box from affecting component performance.

[0014] Optionally, a blocking plate is fixedly provided on the inner edge of the opening of the air deflector, and a plurality of blocking holes are provided on the blocking plate; a sealing plate is provided above the air deflector, and a sealing hole that can overlap with the blocking plate is provided on the sealing plate; the base plate is located on the side of the air deflector facing the box door, and a connecting plate is detachably installed vertically on the side of the base plate facing the air deflector, and one end of a plurality of sealing plates is fixedly connected to the side of the connecting plate away from the base plate; the base plate is slid horizontally on the inner wall of the box, and the box body is provided with a limit member for locking the horizontal sliding position of the base plate.

[0015] By employing this technical solution, the blocking plate and the baffle plate work together to adjust the horizontal position of the baseplate, varying the overlap between the blocking and baffle holes. This allows for flexible control of heat dissipation to accommodate varying operating conditions. The baseplate can be removably secured with a connecting plate, facilitating replacement or repair of the blocking plate as needed. The baseplate slides onto the inner wall of the housing, locked in place by a stopper, enabling precise and stable adjustment of the baseplate position, ultimately enabling precise control of heat dissipation.

[0016] Optionally, the limiting member includes a dovetail slide fixed on the inner wall of the box body, a dovetail groove is provided on the base plate and slides with the dovetail slide, an elastic clip is provided on the inner wall of the dovetail groove, and a plurality of positioning grooves are provided on the dovetail slide for the elastic clip to be snapped into.

[0017] By adopting this technical solution, the dovetail sliders and dovetail grooves slide together, providing stable and precise guidance for the substrate's horizontal sliding along the inner wall of the cabinet. This ensures a smooth sliding process without deviation or shaking, and ensures that components such as the blocking plate associated with the substrate can be accurately adjusted, thereby effectively controlling heat dissipation. The elastic clips mate with the positioning grooves on the dovetail sliders. When the substrate slides to the appropriate position, the elastic clips automatically snap into the positioning grooves, firmly locking the substrate in place and preventing accidental movement due to vibration and other factors during operation, thus ensuring the stability of the equipment.

[0018] Optionally, a plurality of limit blocks are fixed on the side of the connecting plate away from the blocking plate, and a limit slot for the limit blocks to be inserted is provided on the base plate; an extension plate is fixed on the side of the positioning plate facing the blocking plate, and locking blocks close to each other are fixed on the two extension plates, and locking slots are provided on the side and bottom surfaces of the connecting plate; the locking blocks can be inserted into the locking slots when the two locking plates slide toward each other.

[0019] By adopting this technical solution, the locking plugs on the extension plate of the positioning plate can be inserted into the locking slots of the connecting plate when the two locking plates slide toward each other. This design further strengthens the connection strength and stability between the various components, effectively preventing loosening and displacement of components due to factors such as vibration during equipment operation, and ensuring the reliable implementation of the heat dissipation and regulation function. At the same time, this combination of snap-on and plug-in connection ensures convenient installation, reduces installation difficulty and time costs, and facilitates subsequent disassembly, replacement, or maintenance of components.

[0020] Optionally, a guiding slope is provided on the side edge of the locking plug away from the extension plate.

[0021] By adopting this technical solution, when the two locking plates slide toward each other and the locking insert moves toward the locking slot, the guiding bevel provides precise guidance, allowing the locking insert to be inserted more smoothly and easily into the locking slot. Even if there is a certain positional deviation during installation or operation, the guiding bevel can gradually correct the position of the insert with its inclined surface, reducing the difficulty of insertion and avoiding jamming and collisions caused by inaccurate alignment, thereby improving the smoothness and convenience of operation.

[0022] Optionally, the blocking plate is fixed with a rotating shaft toward the end of the connecting plate, and the connecting plate is provided with a rotating socket for the rotating shaft to be inserted and rotated, and the blocking plate can be rotated and adjusted along the axis of the rotating shaft; the inner wall of the box body is provided with second card slots located below the base plate in a horizontal direction side by side; after several of the limit blocks are disengaged from the limit card slots, they can be inserted into the second card slots in a horizontal direction, and the connecting plate is now arranged on the inner wall of the box body in a horizontal direction, and several blocking plates can be rotated to a state parallel to the horizontal plane for placing disassembly and assembly tools.

[0023] By adopting this technical solution, once the limit block is removed from the limit slot and inserted into the second slot, the connecting plate can be placed horizontally against the inner wall of the box. At this point, the blocking plate can be rotated parallel to the horizontal plane, cleverly forming a temporary platform for disassembly and assembly tools. This not only solves the problem of having nowhere to place tools during maintenance and prevents the loss or damage that may result from haphazard placement of tools, but also improves the convenience and efficiency of maintenance operations, eliminating the need for workers to frequently retrieve and place tools in and out of the box. Furthermore, this design fully utilizes the space within the box, eliminating the need for additional dedicated tool storage structures and making the overall structure of the ring main box more compact and reasonable.

[0024] Optionally, a guide strip is fixedly provided on the upper side surface of the connecting plate when the connecting plate is in a horizontal state, and a guide slot for the guide strip to be inserted into is provided on the bottom surface of the positioning plate located on the lower side of the base plate.

[0025] By adopting the above technical solution, when the connecting plate is in a horizontal state, the guide strip on its upper side cooperates with the guide groove on the bottom surface of the positioning plate on the lower side of the base plate, providing accurate longitudinal positioning for the connecting plate.

[0026] In summary, this application has the following beneficial technical effects: When the door is closed, the control element drives the two locking plates to slide toward each other, quickly locking the terminal block and ensuring a secure connection to prevent loosening. When the door is opened, the reset element causes the two locking plates to slide away from each other, automatically unlocking the terminal block for quick removal and maintenance. This design improves the stability and reliability of terminal block installation. BRIEF DESCRIPTION OF THE DRAWINGS

The terminal block 3 is a conventional wiring structure and is not described in detail here. A fixing component 5 is also provided inside the box body 1 to further limit and lock the terminal block 3. When the ring network box is moved, transported or hoisted, the fixing component 5 is used to reduce the possibility of the terminal block 3 being installed loosely.

[0032] Reference Figure 3 Three heat dissipation ports 11 are provided on both side walls of the box body 1, wherein a protective cover 12 with an opening downward is fixed on the outer edge of the opening of the three heat dissipation ports 11, and a guide cover 13 with an opening upward is fixed on the inner edge; the combination of the protective cover 12 and the guide cover 13 reduces the possibility of external rainwater, dust or other impurities entering the interior of the box body 1 through the heat dissipation ports 11.

[0035] Reference Figure 3 and Figure 4 The control member 54 includes a control plate 541 fixed on the inner side of the box door 2, wherein a guide slope 521 is provided on the outer side of the junction of the positioning plate 52 and the locking plate 53; when the box door 2 is closed, the control plate 541 presses the positioning plate 52 along the guide slope 521, thereby causing the two locking plates 53 to slide toward each other, overcoming the elastic force of the reset member 55.

[0036] Reference Figure 5 and Figure 6 The upper side and bottom surfaces of the base plate 4 are provided with limiting slots 42 for the limiting plate 51 to be inserted and slided. Two opposite limiting protrusions 511 are fixed on the outer periphery of the end of the limiting plate 51 away from the positioning plate 52. The side walls of the limiting slots 42 are provided with limiting sliding grooves 421 for the limiting protrusions 511 to be inserted and slided. The reset member 55 is a reset spring 551 in a compressed state in the limit slot 42, wherein the two ends of the reset spring 551 respectively abut against the bottom surface of the limit slot 42 and the side of the limit plate 51 away from the positioning plate 52; when the control plate 541 and the locking plate 53 are misaligned, the two limit plates 51 slide back to back under the pressure of the reset spring 551.

[0038] Reference Figure 9 and Figure 10 The limiting member 6 includes two dovetail slides 61 fixedly arranged on the inner wall of the box body 1 in the horizontal direction. The base plate 4 is provided with a dovetail slide 43 that slides with the dovetail slide 61. The inner wall of the dovetail slide 43 is provided with an elastic clamping member 62. The dovetail slide 61 is provided with a plurality of positioning grooves 611 for the elastic clamping member 62 to be clamped into. The elastic clamping member 62 includes a compression spring 621 and an arc-shaped protrusion 622. A placement groove 431 is formed on the inner wall of the dovetail groove 43 for receiving the compression spring 621 and the arc-shaped protrusion 622. The compression spring 621 presses one side of the arc-shaped protrusion 622, causing the protruding portion of the arc-shaped protrusion 622 to protrude from the opening of the placement groove 431. The outer side surface of the protruding portion of the arc-shaped protrusion 622 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. When the substrate 4 slides along the dovetail slide 61 to a state where the blocking hole and the blocking hole coincide or are misaligned, the protruding portion of the arc-shaped protrusion 622 is locked into the corresponding positioning groove 611 of the device, thereby limiting and locking the sliding position of the substrate 4.

[0039] Reference Figure 11 and Figure 12 The connecting member 7 is a connecting plate 71 detachably mounted vertically on the side of the base plate 4 facing the blocking plate 15, and one end of the three blocking plates 15 facing the connecting plate 71 is commonly connected to the side of the connecting plate 71 away from the base plate 4; two limiting blocks 72 are fixed on the side of the connecting plate 71 away from the blocking plate 15, and a limiting slot 45 for the limiting block 72 to be engaged is opened on the base plate 4; An extension plate 56 is fixedly provided on the side of the positioning plate 52 facing the blocking plate 15, and locking plugs 57 close to each other are fixedly provided on the two extension plates 56. A guiding slope 571 is provided on the side edge of the locking plug 57 away from the extension plate 56, and locking slots 711 are provided on the side and bottom surfaces of the connecting plate 71; when the two locking plates 53 slide toward each other, the locking plugs 57 are synchronously inserted into the corresponding locking slots 711 along their own guiding slopes 571, thereby improving the assembly stability of the connecting plate 71 and the base plate 4.

[0040] Reference Figure 12 、 Figure 13 and Figure 14 The end of the blocking plate 15 facing the connecting plate 71 is fixed with a rotating shaft 151, and the connecting plate 71 is provided with a rotating hole 712 for the rotating shaft 151 to be inserted and rotated. The blocking plate 15 can be rotated and adjusted along the axis of the rotating shaft 151; the inner wall of the box body 1 is provided with a second card slot 16 located below the base plate 4 in a horizontal direction. When connecting the cable to the terminal block 3, the staff can pull out the two limit blocks 72 from the limit slot 45, and then insert the two limit blocks 72 into the second slot 16 in the horizontal direction. At this time, the connecting plate 71 is set on the inner wall of the box body 1 in the horizontal direction, and then the staff rotates the three sealing plates 15 to a state parallel to the horizontal plane. At this time, the three rotated sealing plates 15 together constitute a "platform" for placing disassembly and assembly tools.

[0041] Reference Figure 14 When the connecting plate 71 is in a horizontal state, a guide strip 713 is fixed on the upper side thereof, and a guide groove 522 for the guide strip 713 to be inserted into the bottom surface of the positioning plate 52 on the lower side of the base plate 4 is provided; when the three blocking plates 15 are used as a "platform" for placing tools, the guide strip 713 on the connecting plate 71 is squeezed into the guide groove 522 on the positioning plate 52 under the pressure of the return spring 551, thereby improving the installation stability of the connecting plate 71 in this state.

[0042] The implementation principle of the embodiment of this application is: In normal installation and use, the fixing plug 31 of the terminal block 3 is inserted into the fixing slot 41 of the base plate 4 to complete the preliminary installation; the box door 2 is closed, and the control board 541 on the inside of the box door 2 squeezes the positioning plate 52 along the guide slope 521, so that the two locking plates 53 overcome the elastic force of the reset spring 551 and slide toward each other, locking the terminal block 3, thereby fixing the terminal block 3 and preventing it from loosening; at this time, the base plate 4 is in a position where the heat dissipation port 11 can dissipate heat normally, and the heat dissipation port 11 is combined through the protective cover 12 and the air guide cover 13, and the blocking hole on the blocking plate 14 coincides with the blocking hole on the blocking plate 15, thereby achieving normal ventilation and heat dissipation, and reducing the possibility of external impurities entering the box body 1.

[0043] During transportation or in harsh outdoor environments, the base plate 4 is pushed to slide along the dovetail slide 61, and the arc-shaped protrusion 622 of the elastic clip 62 is snapped into the positioning groove 611 to achieve limiting. The base plate 4 slides through the connecting plate 71 to drive the three blocking plates 15 to slide, so that the blocking hole and the blocking hole are misaligned, completely blocking the heat dissipation port 11 to prevent rainwater, dust, etc. from entering. At the same time, when the two locking plates 53 slide toward each other, the locking plug 57 is inserted into the locking slot 711 of the connecting plate 71, thereby improving the assembly stability of the connecting plate 71 and the base plate 4.

[0044] When the cable is connected and tools need to be placed, the limit block 72 is pulled out from the limit slot 45, and the limit block 72 is inserted into the second slot 16, so that the connecting plate 71 is placed horizontally on the inner wall of the box body 1; then the three blocking plates 15 are rotated to be parallel to the horizontal plane, forming a "platform" for placing disassembly and assembly tools; at this time, the return spring 551 squeezes the guide strip 713 on the connecting plate 71 to fit into the guide slot 522 of the positioning plate 52, thereby improving the installation stability of the connecting plate 71 and facilitating operation by the staff.
