Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to a quick-release protective integrated ring main unit with primary and secondary protection. Background Technology

[0002] In power distribution networks, integrated primary and secondary ring main units (RMUs) are key equipment for ensuring stable grid operation and achieving efficient power distribution. With the growth of urban construction and electricity demand, higher requirements are being placed on the ease of installation and space utilization of RMUs. Against this backdrop, small, compact outdoor RMUs have emerged. They offer advantages such as small size and ease of outdoor installation, better adapting to complex urban environments and effectively meeting the diverse needs of power distribution and control, making them an important choice in current power infrastructure construction.

[0003] In related technologies, a common type of small, compact outdoor ring main unit mainly consists of a cabinet and a door mounted on the cabinet. Structurally, the rear or side walls of the cabinet are securely fixed to mounting brackets with screws, allowing electrical components to be neatly housed within. For terminal block installation, a plug-in method is the mainstream approach to facilitate subsequent disassembly, assembly, and routine maintenance. Specifically, the terminal blocks have protrusions; during installation, they are simply inserted precisely into the corresponding slots on the mounting brackets to complete the installation, making the process simple and efficient.

[0004] However, this seemingly convenient terminal block installation method has significant drawbacks in practical applications. During the transportation of the ring main unit, the bumps and vibrations generated by vehicle movement are unavoidable; during the hoisting process during installation, impact forces can easily arise due to shaking. These situations can all potentially cause the terminal blocks to loosen, and in severe cases, even lead to complete separation of the terminal blocks from the mounting bracket. Once the terminal blocks detach, it will seriously affect the normal operation of the electrical system within the ring main unit, causing power failures, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a quick-release protective integrated primary and secondary ring main unit to solve the problem that the terminal block installation may become loose during the transportation or hoisting of the aforementioned ring main unit.

[0006] The quick-release protective integrated primary and secondary ring network box provided in this application adopts the following technical solution:

[0007] A quick-release protective primary and secondary integrated ring network box includes a box body, terminal blocks, and a door installed on the vertical side of the box body. Heat dissipation vents are provided on both side walls of the box body. Several fixing blocks are fixedly mounted on the terminal blocks. A base plate is installed vertically on the two inner walls of the box body. Fixing slots for the fixing blocks are provided on the side of the base plate away from the side wall of the box body. Limiting plates that can slide up and down are provided on the upper and bottom surfaces of the base plate. Positioning plates are vertically fixed on the side of the limiting plates away from the base plate in the horizontal direction. Locking plates that bend towards each other are vertically fixed on the two positioning plates. A control component is provided inside the door to drive the two limiting plates to slide towards each other. A reset component is provided on the base plate to drive the two limiting plates to slide away from each other. When the door is closed, the control component drives the two locking plates to slide towards each other to lock the terminal blocks. When the door is opened, the reset component drives the two locking plates to slide away from each other to unlock the terminal blocks.

[0008] By adopting the above technical solution, the terminal block achieves initial positioning and installation by embedding the fixing block into the fixing slot of the base plate, which is simple to operate. The combined design of the limiting plate, positioning plate, and locking plate, along with the control components inside the enclosure door and the reset components on the base plate, enables convenient locking and unlocking of the terminal block. When the enclosure door is closed, the control components drive the two locking plates to slide towards each other, quickly locking the terminal block and ensuring a secure connection to prevent loosening; when the enclosure 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 the terminal block installation.

[0009] Optionally, the control component includes a control plate fixed to 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 presses against the positioning plate along the guide slope, causing the two locking plates to slide towards each other.

[0010] By adopting the above technical solution, when the cabinet door is closed, the control board smoothly applies a pressing force to the positioning plate along the guide ramp. Due to the guiding characteristics of the guide ramp, this force can be accurately converted into a power that causes the two locking plates to slide towards each other. Without additional complicated operating steps or tools, the terminal block can be quickly and reliably locked onto the base plate, effectively preventing the terminal block from loosening and ensuring the stability of the electrical connection.

[0011] Optionally, the upper side and bottom surface of the substrate are provided with limiting slots for the insertion and sliding of the limiting plate, the limiting plate is fixed with a limiting protrusion, and the side wall of the limiting slot is provided with a limiting groove for the insertion and sliding of the limiting protrusion; the reset member is a reset spring located in the limiting slot, and the two ends of the reset spring abut against the bottom surface of the limiting slot and the side of the limiting plate away from the positioning plate, respectively.

[0012] By adopting the above technical solution, the reset component is designed as a reset spring located within the limiting slot, with both ends abutting against the bottom surface of the limiting slot and the corresponding side surface of the limiting plate, respectively. When the enclosure door is opened, the reset spring can automatically and smoothly drive the two limiting plates to slide back and forth using its own elastic potential energy, thereby unlocking the terminal block of the locking plate. No manual reset is required, improving the convenience and efficiency of operation. At the same time, this design is compact, occupies little space, and is conducive to the rational layout and optimized utilization of the internal space of the ring main unit.

[0013] Optionally, a downward-facing protective cover is fixed to the outer edge of the opening of several of the heat dissipation vents, and an upward-facing guide cover is fixed to the inner edge of the opening.

[0014] By adopting the above technical solution, a downward-facing protective cover is installed along the outer edge of the heat dissipation vent opening. This effectively prevents rainwater, dust, and debris from directly entering the ring main unit, avoiding damage to the electrical components inside the unit, extending the equipment's service life, reducing the failure rate caused by environmental factors, and improving the stability of equipment operation. Meanwhile, an upward-facing air guide shroud is installed along the inner edge of the heat dissipation vent opening, guiding hot air inside the unit to escape more smoothly upwards. This optimizes the airflow path within the unit, enhances heat dissipation, and helps to dissipate the heat generated by the electrical components in a timely manner, preventing excessively high temperatures inside the unit from affecting component performance.

[0015] Optionally, a baffle plate is fixedly provided along the inner edge of the opening of the flow guide shroud, and the baffle plate has a plurality of baffle holes; a sealing plate is provided above the flow guide plate, and the sealing plate has sealing holes that can coincide with or be misaligned with the baffle holes on the baffle plate; the base plate is located on the side of the flow guide shroud facing the door, and a connecting plate is detachably installed vertically on the side of the base plate facing the flow guide shroud, 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 slidably mounted on the inner wall of the box in the horizontal direction, and the box is provided with a limiting member to limit and lock the horizontal sliding position of the base plate.

[0016] By adopting the above technical solution, the sealing plate and the barrier plate work together. By adjusting the horizontal position of the base plate, the overlap between the sealing hole and the barrier hole can be changed, flexibly controlling the heat dissipation and adapting to different working conditions. The base plate can be detachably installed with a connecting plate to fix the sealing plate, facilitating replacement or maintenance of the sealing plate according to actual conditions. The base plate slides against the inner wall of the enclosure and is locked in place by limiters, allowing operators to accurately and stably adjust the position of the base plate, thereby precisely controlling heat dissipation.

[0017] Optionally, the limiting component includes a dovetail slide bar fixed to the inner wall of the box, a dovetail groove that slides with the dovetail slide bar on the base plate, an elastic snap-fit ​​component on the inner wall of the dovetail groove, and a plurality of positioning grooves for the elastic snap-fit ​​component to snap into on the dovetail slide bar.

[0018] By adopting the above technical solution, the dovetail slide bar and dovetail groove slide in tandem, providing stable and precise guidance for the horizontal sliding of the substrate on the inner wall of the housing. This ensures a smooth sliding process without deviation or shaking, guaranteeing that components such as the sealing plate associated with the substrate can be accurately positioned, thereby achieving effective control of heat dissipation. The elastic snap-fit ​​component cooperates with the positioning groove on the dovetail slide bar. When the substrate slides to the appropriate position, the elastic snap-fit ​​component automatically engages with the positioning groove, firmly locking the substrate and preventing accidental movement due to vibration or other factors during operation, thus ensuring the stability of the equipment operation.

[0019] Optionally, a plurality of limiting blocks are fixed on the side of the connecting plate away from the sealing plate, and a limiting slot is provided on the base plate for the limiting blocks to be engaged; an extension plate is fixed on the side of the positioning plate facing the sealing plate, and locking blocks that are close to each other are fixed on the two extension plates; a locking slot is provided on the side and bottom surface of the connecting plate; the locking block can be inserted into the locking slot when the two locking plates slide towards each other.

[0020] By adopting the above technical solution, the locking block on the extension plate of the positioning plate can be inserted into the locking slot of the connecting plate when the two locking plates slide towards each other. This design further strengthens the connection strength and stability between the components, effectively preventing the components from loosening or shifting due to vibration and other factors during equipment operation, and ensuring the reliable realization of the heat dissipation and regulation function. At the same time, this connection method combining snap-fit ​​and plug-in not only ensures the convenience of installation, reduces the difficulty and time cost of installation, but also facilitates the disassembly, replacement or maintenance of components in the later stage.

[0021] Optionally, a guide slope is provided on the side edge of the locking block away from the extension plate.

[0022] By adopting the above technical solution, when the two locking plates slide towards each other and the locking block moves towards the locking slot, the guide slope can play a precise guiding role. It allows the locking block to be inserted into the locking slot more smoothly and easily. Even if there is a certain positional deviation during installation or operation, the guide slope can gradually correct the position of the block with its inclined surface, reducing the difficulty of insertion and avoiding jamming or collision due to inaccurate alignment, thus improving the smoothness and convenience of operation.

[0023] Optionally, the sealing plate is fixed with a rotating shaft at its end facing the connecting plate, and the connecting plate has a rotating insertion hole for the rotating shaft to be inserted and rotated. The sealing plate can be adjusted by rotating along the axis of the rotating shaft. A second slot located below the base plate is arranged in a horizontal direction on the inner wall of the box. After the limiting blocks are dislodged from the limiting slots, they can be inserted into the second slots in a horizontal direction. At this time, the connecting plate is set in a horizontal direction on the inner wall of the box, and the sealing plates can be rotated to a state parallel to the horizontal plane for placing disassembly and assembly tools.

[0024] By adopting the above technical solution, after the limiting block disengages from the limiting slot and inserts into the second slot, the connecting plate can be placed horizontally on the inner wall of the box. At this time, the sealing plate can rotate to be parallel to the horizontal plane, cleverly forming a platform for temporarily placing disassembly and assembly tools. This not only solves the problem of where to place tools during maintenance and avoids the loss or damage that may be caused by random placement of tools, but also improves the convenience and efficiency of maintenance operations, eliminating the need for staff to frequently retrieve and place tools inside and outside the box. At the same time, this design makes full use of the internal space of the box, eliminating the need for additional dedicated tool placement structures, making the overall structure of the ring network box more compact and reasonable.

[0025] Optionally, when the connecting plate is in a horizontal state, a guide strip is fixed on the upper side, and a guide groove is opened on the bottom surface of the positioning plate located on the lower side of the base plate for the guide strip to be inserted.

[0026] 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 substrate to provide accurate longitudinal positioning for the connecting plate.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] When the enclosure door is closed, the control unit moves the two locking plates towards each other, quickly locking the terminal block to ensure a secure connection and prevent loosening. When the enclosure door is opened, the reset unit moves the two locking plates away from each other, automatically unlocking the terminal block for easy disassembly and maintenance. This design improves the stability and reliability of the terminal block installation. Attached Figure Description

[0045] The present application will be further described in detail below with reference to all the accompanying drawings.

[0046] Example:

[0047] Reference Figure 1 , Figure 2 and Figure 3 A quick-release protective integrated ring mesh box includes a box body 1, a terminal block 3, and a box door 2 installed on the vertical side of the box body 1. One vertical edge of the box door 2 is rotatably connected to the opening edge of the box body 1, and the other vertical edge of the box door 2 is detachably connected to the box body 1 through a conventional locking structure.

[0048] The two inner walls of the housing 1 are vertically mounted with base plates 4 to support the installation of terminal blocks 3. The terminal blocks 3 have a conventional wiring structure, which will not be described in detail here. The housing 1 is also equipped with a fixing component 5 to further limit and lock the terminal blocks 3. When the ring network box is moved, transported or hoisted, the fixing component 5 reduces the possibility of the terminal blocks 3 becoming loose.

[0049] Reference Figure 3 Three heat dissipation vents 11 are provided on both sides of the housing 1. A protective cover 12 with an opening facing downward is fixed on the outer edge of the opening of the three heat dissipation vents 11, and a guide cover 13 with an opening facing upward is fixed on the inner edge. The combination of the protective cover 12 and the guide cover 13 reduces the possibility of rainwater, dust or other impurities from the outside entering the housing 1 through the heat dissipation vents 11.

[0050] Reference Figure 4Two fixing blocks 31 are fixed on the terminal block 3. Two fixing slots 41 corresponding to the fixing blocks 31 are opened on the side of the base plate 4 away from the side wall of the housing 1. When the terminal block 3 is initially installed, the fixing blocks 31 on the terminal block 3 are aligned with the fixing slots 41 on the base plate 4, and then the fixing blocks 31 are inserted into the fixing slots 41.

[0051] Reference Figure 3 , Figure 4 and Figure 5 The fixing component 5 includes two limiting plates 51 that are slidably disposed on the upper side and bottom surface of the substrate 4. Both limiting plates 51 can slide up and down. On the side of the limiting plates 51 away from the substrate 4, a positioning plate 52 is vertically fixed in the horizontal direction. On the two positioning plates 52, a locking plate 53 that is bent in the direction of approaching each other is vertically fixed.

[0052] The door 2 is equipped with a control component 54 that drives the two limiting plates 51 to slide towards each other, and the base plate 4 is equipped with a reset component 55 that drives the two limiting plates 51 to slide away from each other. When the door 2 is closed, the control component 54 drives the two locking plates 53 to slide towards each other to lock the terminal block 3. When the door 2 is opened, the reset component 55 drives the two locking plates 53 to slide away from each other to unlock the terminal block 3.

[0053] Reference Figure 3 and Figure 4 The control component 54 includes a control plate 541 fixed on the inner side of the door 2, wherein a guide slope 521 is provided on the outer side of the connection between the positioning plate 52 and the locking plate 53; when the 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 towards each other against the elastic force of the reset component 55.

[0054] Reference Figure 5 and Figure 6 The upper side and bottom surface of the substrate 4 are provided with limiting slots 42 for the limiting plate 51 to be inserted and slid. Two opposing 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 wall of the limiting slot 42 is provided with a limiting groove 421 for the limiting protrusions 511 to be inserted and slid.

[0055] The reset component 55 is a reset spring 551 that is in a compressed state inside the limiting slot 42. The two ends of the reset spring 551 abut against the bottom surface of the limiting slot 42 and the side of the limiting plate 51 away from the positioning plate 52, respectively. When the control plate 541 and the locking plate 53 are misaligned, the two limiting plates 51 slide in opposite directions under the pressure of the reset spring 551.

[0056] Reference Figure 7 and Figure 8A baffle plate 14 is fixedly provided on the inner edge of the opening of the flow guide shroud 13, and a plurality of baffle holes are provided on the baffle plate 14; a sealing plate 15 is provided above the flow guide plate, and a sealing hole is provided on the sealing plate 15 that can coincide with or be misaligned with the baffle holes on the baffle plate 14; the base plate 4 is located on the side of the flow guide shroud 13 facing the door 2, and the base plate 4 is slidably mounted on the inner wall of the box 1 in the horizontal direction, and a limiting member 6 is provided on the box 1 to limit and lock the horizontal sliding position of the base plate 4; a connecting member 7 is provided on the side of the base plate 4 facing the flow guide shroud 13 to drive the sealing plate 15 to slide and adjust.

[0057] During transportation or in harsh outdoor environments, staff can adjust the horizontal position of the substrate 4, and then drive the three sealing plates 15 to slide through the connector 7, so that the sealing holes on the sealing plates 15 are misaligned with the blocking holes on the barrier plates 14, thereby completely sealing the heat dissipation vent 11; when the outdoor environment is good, the substrate 4 can be slid back to its original position, so that the ring network box can reuse the heat dissipation vent 11 for heat dissipation.

[0058] Reference Figure 9 and Figure 10 The limiting member 6 includes two dovetail slide bars 61 fixed in the horizontal direction on the inner wall of the box 1. The base plate 4 is provided with a dovetail slide groove 43 that slides with the dovetail slide bars 61. An elastic snap-fit ​​member 62 is provided on the inner wall of the dovetail slide groove 43. A plurality of positioning grooves 611 are provided on the dovetail slide bars 61 for the elastic snap-fit ​​member 62 to snap into.

[0059] The elastic snap-fit ​​component 62 includes a compression spring 621 and an arc-shaped protrusion 622. The inner wall of the dovetail groove 43 is provided with a placement groove 431 for the compression spring 621 and the arc-shaped protrusion 622 to be placed. The compression spring 621 presses one side of the arc-shaped protrusion 622, causing the protruding part of the arc-shaped protrusion 622 to protrude from the opening of the placement groove 431. The outer surface of the protruding part of the arc-shaped protrusion 622 is an arc surface, and the arc length corresponding to the arc surface is a minor arc.

[0060] When the substrate 4 slides along the dovetail slide bar 61 to the point where the sealing hole and the blocking hole coincide or are misaligned, the protruding part of the arc-shaped protrusion 622 is engaged in the corresponding positioning groove 611 of the device, thereby limiting and locking the sliding position of the substrate 4.

[0061] Reference Figure 11 and Figure 12 The connector 7 is a connector plate 71 that is detachably installed vertically on the side of the substrate 4 facing the sealing plate 15, and one end of the three sealing plates 15 facing the connector plate 71 is connected to the side of the connector plate 71 away from the substrate 4; two limiting blocks 72 are fixed on the side of the connector plate 71 away from the sealing plate 15, and the substrate 4 is provided with a limiting slot 45 for the limiting blocks 72 to be inserted;

[0062] An extension plate 56 is fixed on the side of the positioning plate 52 facing the sealing plate 15. Locking blocks 57 close to each other are fixed on the two extension plates 56. A guide slope 571 is provided on the side edge of the locking block 57 away from the extension plate 56. Locking slots 711 are provided on the upper side and bottom surface of the connecting plate 71. When the two locking plates 53 slide towards each other, the locking block 57 is inserted into the corresponding locking slot 711 along its own guide slope 571, thereby improving the assembly stability of the connecting plate 71 and the base plate 4.

[0063] Reference Figure 12 , Figure 13 and Figure 14 The sealing plate 15 is fixed with a rotating shaft 151 at the end facing the connecting plate 71. The connecting plate 71 is provided with a rotating insertion hole 712 for the rotating shaft 151 to be inserted and rotated. The sealing plate 15 can be rotated and adjusted along the axis of the rotating shaft 151. The inner wall of the box 1 is provided with a second slot 16 located below the base plate 4 in a horizontal direction.

[0064] When connecting the cable to the terminal block 3, the operator can pull out the two limit blocks 72 from the limit slots 45 and then insert the two limit blocks 72 horizontally into the second slot 16. At this time, the connecting plate 71 is set horizontally on the inner wall of the box 1. Then, the operator rotates the three sealing plates 15 to a state parallel to the horizontal plane. At this time, the three rotated sealing plates 15 together form a "platform" for placing disassembly and assembly tools.

[0065] Reference Figure 14 When the connecting plate 71 is in a horizontal state, a guide strip 713 is fixed on its upper side. A guide groove 522 for the guide strip 713 to be inserted is opened on the bottom surface of the positioning plate 52 located on the lower side of the base plate 4. When the three sealing plates 15 are used as a "platform" for placing tools, the guide strip 713 on the connecting plate 71 is inserted into the guide groove 522 on the positioning plate 52 under the compression of the return spring 551, thereby improving the installation stability of the connecting plate 71 in this state.

[0066] The implementation principle of this application embodiment is as follows:

[0067] 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 initial installation; the box door 2 is closed, and the control plate 541 on the inside of the box door 2 presses the positioning plate 52 along the guide slope 521, so that the two locking plates 53 slide against each other against the elastic force of the return spring 551, locking the terminal block 3 and fixing the terminal block 3 to prevent loosening; at this time, the base plate 4 is in the position where the heat dissipation vent 11 can dissipate heat normally. The heat dissipation vent 11 is combined with the protective cover 12 and the flow guide cover 13, and the blocking hole on the barrier plate 14 coincides with the blocking hole on the sealing plate 15 to achieve normal ventilation and heat dissipation, while reducing the possibility of external impurities entering the box 1.

[0068] During transportation or in harsh outdoor environments, the substrate 4 is pushed to slide along the dovetail slide bar 61, and the arc-shaped protrusion 622 of the elastic snap-fit ​​member 62 is engaged in the positioning groove 611 to achieve limiting; the sliding of the substrate 4 drives the three sealing plates 15 to slide through the connecting plate 71, so that the sealing hole and the barrier hole are misaligned, completely sealing the heat dissipation port 11 and preventing rainwater, dust and other substances from entering; at the same time, when the two locking plates 53 slide towards each other, the locking plug 57 is inserted into the locking slot 711 of the connecting plate 71, improving the assembly stability of the connecting plate 71 and the substrate 4.

[0069] When the cable is connected and tools need to be placed, pull the limit block 72 out of the limit slot 45 and insert the limit block 72 into the second slot 16 so that the connecting plate 71 is placed horizontally on the inner wall of the box 1; then rotate the three sealing plates 15 to be parallel to the horizontal plane to form a "platform" for placing the disassembly and assembly tools; at this time, the return spring 551 squeezes and causes the guide strip 713 on the connecting plate 71 to be engaged in the guide slot 522 of the positioning plate 52, which improves the installation stability of the connecting plate 71 and facilitates the operation of the staff.
