Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and in particular to a comprehensive distribution box that facilitates capacitor installation. Background Technology

[0002] In power distribution systems, the integrated distribution box, fixed beneath the pole-mounted transformer, plays a crucial role. As a key node in power distribution and control, it is responsible for the rational allocation of the transformer's output power to various consumer terminals. The integrated distribution box has a complex internal structure, with specialized compartments for different functions, forming multiple independent chambers. One of these chambers is specifically designed for installing capacitors. Capacitors play a role in reactive power compensation in the distribution system, effectively improving the power factor, reducing line losses, and ensuring the stable operation of the power system. Therefore, the reliable installation of capacitors is essential for the normal operation of the integrated distribution box and the entire power system.

[0003] Currently, a fairly conventional fixing method is commonly used when installing capacitors in integrated distribution boxes. The capacitor has corresponding mounting lugs on its bottom side, with through holes on the lugs. During the capacitor fixing process, the operator first places the capacitor into a specially designed mounting cavity. Then, the capacitor's position is carefully adjusted so that the through holes on the mounting lugs precisely align with the pre-drilled screw holes on the bottom side of the cavity. After alignment, a tool is used to insert a screw through the through hole and slowly screw it into the screw hole. The screw's engagement with the screw thread securely fixes the capacitor to the bottom of the cavity, ensuring its stability during operation.

[0004] Because the internal space of the integrated distribution box is relatively small, the operable space is further compressed after the capacitor is placed inside. Tightening or loosening screws in such a confined space significantly increases the difficulty for workers and severely limits the use of tools. Moreover, during screw tightening, the limited operating space and potential slight wobbling can easily cause the previously aligned through holes and screw holes to become misaligned again. Once misalignment occurs, workers need to readjust the capacitor position multiple times, which not only consumes a lot of time and effort but also seriously affects the overall fixing efficiency of the capacitor, causing numerous problems for the installation and maintenance of electrical equipment. Summary of the Invention

[0005] The purpose of this application is to provide a comprehensive distribution box that facilitates capacitor installation, thereby solving the problem of low overall efficiency in the process of installing capacitors into the comprehensive distribution box in the aforementioned related technologies.

[0006] The integrated distribution box for easy capacitor installation provided in this application adopts the following technical solution:

[0007] A comprehensive distribution box for easy capacitor installation includes a box body and a door rotatably mounted on the box body. Several heat dissipation vents communicating with a mounting cavity are provided on the vertical sidewalls of the box body. A mounting cavity for inserting capacitors is provided inside the box body. Support plates are horizontally fixed on two opposing inner walls of the mounting cavity of the box body. Two horizontal plates are arranged side-by-side inside the mounting cavity, with their ends detachably connected to the upper sides of the two support plates. Limiting blocks are fixed on the upper sides of the horizontal plates, each with a limiting notch on its upper side for the bottom of the capacitor to be inserted and fixed. Connecting ports communicating with the limiting notches are provided on the adjacent sides of the opposing limiting blocks on the two horizontal plates.

[0008] By adopting the above technical solution, this integrated distribution box significantly improves capacitor installation efficiency. The limiting blocks are pre-installed on the horizontal plate, which is then installed to the corresponding position on the receiving plate, completing the "pre-installation" layout. When installing capacitors, workers no longer need to perform complex screw tightening operations in confined spaces; they only need to insert the bottom of the capacitor into the limiting notch to complete the initial fixation, greatly simplifying the installation process. This not only reduces operational difficulty but also avoids the problem of misaligned through holes and screw holes caused by space constraints, reducing the hassle of repeated corrections, effectively saving time and effort, and solving the problem of low overall efficiency in installing capacitors inside the integrated distribution box.

[0009] Optionally, a fixing plate is provided above the horizontal plate, and extension plates facing the inner wall of the mounting cavity are fixed on the opposite two sides of the fixing plate; a driving component for moving the extension plates up and down is fixed on the inner wall of the box, and an elastic pad is fixed on the bottom side of the fixing plate, which can abut against the upper side of the capacitor mounted on the horizontal plate when the fixing plate moves down.

[0010] By adopting the above technical solution, after the capacitor is initially fixed by the bottom locking notch, the driving component can move the fixing plate downwards, causing the elastic pad on the bottom side of the fixing plate to press firmly against the upper side of the capacitor. This design achieves secondary positioning of the capacitor, effectively reducing potential swaying during operation and improving the reliability of capacitor installation. Simultaneously, the elastic pad also acts as a buffer, reducing the impact of external vibrations on the capacitor, ensuring stable operation of the capacitor within the integrated distribution box, extending its service life, and improving the safety and stability of the entire power distribution system.

[0011] Optionally, the driving component includes an electric cylinder fixed vertically to the inner wall of the housing, the telescopic rod of the electric cylinder being vertically downward and fixedly connected to the upper side of the extension plate.

[0012] By adopting the above technical solution, workers can precisely control the extension and retraction of the electric cylinder's telescopic rod, thereby flexibly adjusting the position of the fixing plate to provide ample space for capacitor installation. After installation, the fixing plate can be lowered to ensure the elastic pad tightly presses against the capacitor. Moreover, the electric cylinder operates smoothly and has stable power output, ensuring smooth movement of the fixing plate, guaranteeing the effectiveness of capacitor limiting, and improving the reliability of capacitor installation and operation in the integrated distribution box.

[0013] Optionally, a sealing plate is slidably provided on the inner wall of the housing near the heat dissipation vent, and an elastic reset component is provided to drive the sealing plate to move upward; a control component is provided on the fixed plate to drive the sealing plate to move downward, and a sealing opening is opened on the sealing plate that coincides with the heat dissipation vent. When the sealing plate moves upward, it coincides with the heat dissipation vent, and when it moves downward, the heat dissipation vent is misaligned and blocked.

[0014] By adopting the above technical solution, in calm outdoor weather, the elastic reset component moves the sealing plate upward, aligning the sealing opening with the heat dissipation vent, ensuring normal heat dissipation, maintaining a suitable temperature inside the enclosure, and guaranteeing stable operation of components such as capacitors. However, in windy weather, the control components on the fixed plate can move the sealing plate downward, misaligning the heat dissipation vent with the sealing opening, effectively sealing the heat dissipation vent, reducing the possibility of external dust and impurities entering the enclosure through the vent, minimizing damage to components such as capacitors, improving the adaptability and protection capabilities of the integrated distribution box in different environments, and extending the equipment's service life.

[0015] Optionally, a positioning rod is fixedly provided on the two vertically opposite sides of the sealing plate along the vertical direction. The elastic reset component includes a first spring, a guide block fixed on the inner wall of the box, and a baffle fixed on the outer periphery of the positioning rod. The guide block has a guide hole for the positioning rod to pass through. The guide block is located below the baffle. The two ends of the first spring are fixedly connected to the sides of the guide block and the baffle that are close to each other.

[0016] By adopting the above technical solution, the elastic reset component composed of the guide block, baffle and first spring is compressed and stores energy after the control component moves the sealing plate down in windy weather; when the weather returns to calm, the elastic force of the first spring can push the baffle and sealing plate up and reset, realizing the automatic opening of the heat dissipation vent without manual intervention, which improves the automation level and operating efficiency of the integrated power distribution box in response to different environments.

[0017] Optionally, the control component includes two control rods mounted above the fixing plate and two control protrusions fixed on the vertical side of the sealing plate. The ends of the control rods away from the fixing plate are located above the control protrusions. When the control rods move down with the fixing plate, they can squeeze the control protrusions to drive the sealing plate down.

[0018] By adopting the above technical solution, when it is necessary to block the heat dissipation vent, the fixing plate moves downward, and the control rod above it moves downward simultaneously. This exerts a squeezing effect on the control protrusion on the vertical side of the blocking plate, pushing the blocking plate downward and misaligning the heat dissipation vent with the blocking opening to complete the blockage. Simultaneously, the cooperation between the control rod and the control protrusion accurately transmits force, ensuring the blocking plate moves into place effectively. This effectively copes with severe weather such as strong winds, enhances the protective performance of the integrated distribution box, and ensures the stable operation of internal components.

[0019] Optionally, the end of the control lever away from the control protrusion is rotatably connected to the upper side of the fixing plate, and a locking member is provided above the fixing plate to adjust and fix the rotation of the control lever; a support block is fixedly provided on the upper side of the extension plate, and a support notch is provided on the vertical side of the support block; the end of the control lever away from the fixing plate can rotate the upper side of the extension plate and insert into the inside of the support notch; the control lever can rotate the upper side of the fixing plate.

[0020] By adopting the above technical solution, when there is no need to control the downward movement of the sealing plate, the control rod can be rotated to the upper side of the extension plate and inserted into the support notch of the support block. At this time, the assembly stability of the fixing plate and the extension plate can be enhanced by the control rod. When it is necessary to control the sealing plate, the control rod can be rotated to the appropriate position to apply force to the control protrusion. The locking component further ensures the stability of the control rod after adjustment, making the entire control process more reliable and improving the accuracy and convenience of switching between heat dissipation and protection functions of the integrated distribution box under different operating conditions.

[0021] Optionally, the extension plate has a first groove on its upper side, the fixing plate has a second groove on its upper side, and the bottom side of the end of the control rod away from the fixing plate is provided with an elastic snap-fit ​​member that can be snapped into the first groove and the second groove.

[0022] By adopting the above technical solution, when one end of the control rod rotates and engages inside the support notch, the elastic locking component simultaneously engages into the first groove; when one end of the control rod rotates to the side of the fixed plate for adjustment and storage / transportation, the elastic locking component simultaneously engages into the second groove; thereby improving the stability of the control rod in both states.

[0023] Optionally, a receiving groove is provided on the upper side of the fixed plate near the edge of the box door. A locking rod is rotatably connected to the inner wall of the receiving groove. A locking block is fixed on the inner wall of the box door. A locking notch is provided on the upper side of the locking block. The locking rod can be rotated to a horizontal state away from the fixed plate and unfolded and fixed, and rotated to the receiving groove towards the fixed plate and stored and fixed. When the locking rod is unfolded and fixed, a locking insert is fixed on the bottom side of the end away from the fixed plate. In this state, the locking insert can move down with the fixed plate and be inserted into the locking notch.

[0024] By adopting the above technical solution, during the downward movement of the fixing plate, the locking rod is rotated away from the fixing plate to a horizontal position for fixation. At this time, the locking insert at the bottom of the locking rod end can accurately insert into the locking notch on the locking block on the inner wall of the box door as the fixing plate moves downward, effectively preventing the box door from being opened accidentally and ensuring the safety of the internal components of the integrated distribution box. When it is not necessary to lock the box door, the locking rod can be rotated towards the fixing plate and stored in the receiving groove, without occupying extra space or affecting the normal opening and closing of the box door. This adjustable locking design is convenient to operate and can effectively improve the protection performance and safety of the distribution box.

[0025] Optionally, the control lever can be rotated above the receiving trough to abut and limit the upper side of the locking lever located within the receiving trough.

[0026] By adopting the above technical solution, when the control lever is rotated above the receiving trough, it can abut and limit the upper side of the locking lever inside the receiving trough, preventing the locking lever from shaking in the working or non-working state, and ensuring the stability of the unfolded and retracted states.

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

[0028] This integrated distribution box significantly improves capacitor installation efficiency. The limiting blocks are pre-installed on the horizontal plate, which is then installed onto the corresponding position on the receiving plate, completing the "pre-installation" layout. When installing capacitors, workers no longer need to perform complex screw tightening operations in confined spaces; they only need to insert the bottom of the capacitor into the limiting notch to complete the initial fixation, greatly simplifying the installation process.

[0042] The present application will be further described in detail below with reference to all the accompanying drawings.

[0043] Example 1:

[0044] Reference Figure 1 and Figure 2A comprehensive distribution box for easy capacitor installation includes a box body 1 and a door 2 rotatably mounted on the box body 1. Several heat dissipation vents 11 communicating with mounting cavities 13 are provided on the vertical side wall of the box body 1. A downward-facing guide shroud 12 is fixed to the outer edge of the opening of the heat dissipation vent 11. One side of the door 2 is hinged to the edge of the opening of the box body 1, and the other side of the door 2 is locked to the box body 1 by a conventional locking structure. The box body 1 is provided with mounting cavities 13 for capacitors to be placed inside.

[0045] Reference Figure 2 and Figure 3 The housing 1 is equipped with a support assembly 3, which includes a support plate 31 fixed horizontally on two opposing inner walls of the mounting cavity 13. Two horizontal plates 32 are arranged side by side in the mounting cavity 13. The two ends of the two horizontal plates 32 are detachably connected to the upper side of the two support plates 31 by wing screws, and the installation position of the horizontal plates 32 can be slidably adjusted along the length of the support plates 31 according to the actual situation.

[0046] The upper side of the horizontal plate 32 is fixed with a limiting block 33 by screws. The upper side of the limiting block 33 is provided with a limiting notch 331 for the bottom of the capacitor to be inserted and fixed. The sides of the limiting blocks 33 on the two horizontal plates 32 that are close to each other are provided with a connecting port 332 that communicates with the limiting notch 331.

[0047] The implementation principle of this application embodiment is as follows:

[0048] During capacitor installation, workers can pre-install the limiting block 33 on the horizontal plate 32, and then install the horizontal plate 32 on the corresponding position on the receiving plate 31. This "pre-installation" improves the efficiency of subsequent capacitor installation, so that when subsequent capacitors are installed on the limiting block 33, no additional screws are needed for fixing. The bottom of the capacitor can simply be inserted into the limiting notch 331.

[0049] Example 2:

[0050] Reference Figure 4 and Figure 5 The difference between this embodiment and Embodiment 1 is that a fixing component 4 is provided above the horizontal plate 32, wherein the fixing component 4 includes a fixing plate 41 located above the installed capacitor, wherein two extension plates 42 are integrally formed on opposite sides of the fixing plate 41 facing the inner wall of the mounting cavity 13; a driving member 43 for driving the extension plates 42 to move up and down is fixed on the inner wall of the housing 1, wherein the driving member 43 includes an electric cylinder 431 fixed on the inner wall of the housing 1 in a vertical direction, and the telescopic rod of the electric cylinder 431 is vertically downward and fixedly connected to the upper side of the extension plate 42, while an elastic pad 411 made of rubber is fixed on the bottom side of the fixing plate 41;

[0051] During capacitor installation, the driving component 43 drives the fixing plate 41 to move upward, leaving sufficient installation space; after installation, the fixing plate 41 is driven to move downward, at which time the elastic pad 411 can press against the upper side of the capacitor installed on the horizontal plate 32, thereby further limiting the capacitor in the mounting cavity 13.

[0052] Reference Figure 5 and Figure 6 A sealing assembly 5 is provided on the inner wall of the housing 1 near the heat dissipation vent 11. The sealing assembly 5 includes a sealing plate 51 that slides on the vertical inner wall of the housing 1 and an elastic reset member 52 that is installed on the inner wall of the housing 1 to drive the sealing plate 51 to move upward. A control member 53 that drives the sealing plate 51 to move downward is provided on the fixing plate 41. The sealing plate 51 has a sealing opening 511 that coincides with the heat dissipation vent 11.

[0053] In calm outdoor weather, the sealing plate 51 is moved upward, at which point the heat dissipation vent 11 and the sealing opening 511 coincide, ensuring its heat dissipation performance. In windy outdoor weather, the sealing plate 51 can be moved downward by the control component 53, at which point the heat dissipation vent 11 and the sealing opening 511 are misaligned, thereby sealing the heat dissipation vent 11 and reducing the possibility of external dust or other impurities entering the interior of the housing 1 through the heat dissipation vent 11.

[0054] Reference Figure 7 Positioning rods 512 are fixedly provided on the two vertical sides of the sealing plate 51 along the vertical direction. The elastic reset member 52 includes a first spring 521, a guide block 522 fixed on the inner wall of the box 1, and a baffle 523 fixed on the outer periphery of the positioning rod 512. The guide block 522 has a guide hole for the positioning rod 512 to pass through. The guide block 522 is located below the baffle 523. The two ends of the first spring 521 are fixedly connected to the sides of the guide block 522 and the baffle 523 that are close to each other.

[0055] Reference Figure 5 and Figure 7 The control component 53 includes two control rods 531 mounted on the top of the fixed plate 41 and a control protrusion 532 fixed on the vertical side of the sealing plate 51. The end of the control rod 531 away from the fixed plate 41 is located above the control protrusion 532. When the control rod 531 moves down with the fixed plate 41, it can squeeze the control protrusion 532 to drive the sealing plate 51 to move down.

[0056] When there is a strong wind outdoors, the drive component 43 moves the fixing plate 41 downward, so that the elastic pad 411 on the lower side of the fixing plate 41 comes into contact with the upper side of the capacitor. At the same time, the control rod 531 is driven to squeeze the control protrusion 532, which in turn drives the sealing plate 51 to move downward, so that the heat dissipation port 11 and the sealing port 511 are misaligned. This can improve the installation stability of the capacitor in windy weather and also improve the protection performance in this weather.

[0057] Reference Figure 7 and Figure 8 The end of the control lever 531 away from the control protrusion 532 is rotatably connected to the upper side of the fixing plate 41. The upper part of the fixing plate 41 is provided with a locking member 54 for adjusting and fixing the rotation of the control lever 531. The operator can adjust the installation angle of the control lever 531 by controlling the locking member 54.

[0058] The upper side of the fixing plate 41 has a locking screw hole, and the end of the control rod 531 has a locking through hole. The locking component 54 is a locking bolt 541 that passes through the locking through hole and screws into the locking screw hole. The locking bolt 541 is a wing bolt and can be tightened or loosened manually. When the fixing plate 41, control rod 531 and extension plate 42 are transported as a whole, the upper side of the fixing plate 41 can be rotated to reduce the overall volume during packaging and reduce transportation costs.

[0059] Reference Figure 9 A support block 44 is fixed on the upper side of the extension plate 42, and a support notch 441 is provided on the vertical side of the support block 44. When the application environment is good and it is not necessary to control the downward movement of the sealing plate 51, the end of the control rod 531 away from the fixed plate 41 can rotate the upper side of the extension plate 42 and insert it into the support notch 441. At this time, the control rod 531 can enhance the connection stability between the fixed plate 41 and the extension plate 42.

[0060] Reference Figure 8 , Figure 9 and Figure 10 The upper side of the extension plate 42 is provided with a first groove 421, and the upper side of the fixing plate 41 is provided with a second groove 412. The bottom side of the end of the control rod 531 away from the fixing plate 41 is provided with an elastic snap-fit ​​member 55 that can be snapped into the first groove 421 and the second groove 412.

[0061] The elastic snap-fit ​​component 55 includes a compression spring 551 and an arc-shaped protrusion 552. The extension plate 42 has a placement groove 5311 for the compression spring 551 and the arc-shaped protrusion 552 to be placed in. The compression spring 551 presses one side of the arc-shaped protrusion 552, causing a part of the arc-shaped protrusion 552 to protrude from the opening of the placement groove 5311. The protruding part of the arc-shaped protrusion 552 is an arc surface, and the protrusion corresponding to the arc surface is a minor arc.

[0062] When one end of the control lever 531 rotates and engages with the support notch 441, the elastic locking member 55 simultaneously engages with the first groove 421; when one end of the control lever 531 rotates to the upper side of the fixing plate 41 for adjustment and storage / transportation, the elastic locking member 55 simultaneously engages with the second groove 412; thereby improving the stability of the control lever 531 in both states.

[0063] Reference Figure 9 and Figure 11 A receiving groove 413 is provided on the upper side of the fixing plate 41 near the edge of the box door 2. The inner wall of the receiving groove 413 is provided with a locking component 6. The locking component 6 includes a locking rod 61 with one end rotatably connected to the inner wall of the receiving groove 413. A locking block 21 is fixed on the inner wall of the box door 2. A locking notch 211 is provided on the upper side of the locking block 21.

[0064] The locking rod 61 can be rotated to a horizontal position away from the fixing plate 41 and unfolded and fixed, and rotated to a position closer to the fixing plate 41 and stored and fixed in the receiving groove 413; when the locking rod 61 is unfolded and fixed, a locking insert 62 is fixed on the bottom side of the end away from the fixing plate 41; when the locking rod 61 is not needed for locking and protection, the locking rod 61 can be rotated into the receiving groove 413 and stored and fixed.

[0065] When locking protection is required using the locking lever 61, the locking lever 61 can be rotated out of the receiving groove 413 to a horizontal state and fixed. Then, when the driving member 43 moves the fixing plate 41 down to a state of contact with the upper side of the capacitor, the locking plug 62 can move down with the fixing plate 41 and be inserted into the locking notch 211, thereby further locking the cabinet door 2 and reducing the possibility of unauthorized personnel opening the cabinet door 2.

[0066] Reference Figure 9 and Figure 11 When the control lever 531 can be rotated above the receiving trough 413, it abuts against and limits the upper side of the locking lever 61 located in the receiving trough 413; that is, when the locking lever 61 is unfolded or retracted to a horizontal state, the horizontal control lever 531 can be limited and fixed by rotating and adjusting the control lever 531.

[0067] The implementation principle of this application embodiment is as follows:

[0068] During capacitor installation, the electric cylinder 431 moves the fixing plate 41 upward to provide space; after installation, the electric cylinder 431 moves the fixing plate 41 downward, and the elastic pad 411 on its bottom side presses against the capacitor, thereby further limiting the capacitor in the mounting cavity 13 and ensuring the stability of the capacitor.

[0069] In calm outdoor weather, the elastic reset component 52 moves the sealing plate 51 upward, and the heat dissipation vent 11 and the sealing port 511 coincide to ensure heat dissipation; in windy weather, the drive component 43 moves the fixed plate 41 downward, and the control rod 531 squeezes the control protrusion 532, which moves the sealing plate 51 downward, and the heat dissipation vent 11 and the sealing port 511 are misaligned to seal the heat dissipation vent 11, reducing the entry of dust and impurities.

[0070] When the fixed plate 41, extension plate 42 and control rod 531 are transported as a whole as components, the control rod 531 is rotated to the upper side of the fixed plate 41 and fixed with the butterfly locking bolt 541 to reduce the volume and reduce the cost. When the environment is good, the control rod 531 is rotated to the support notch 441 of the extension plate 42, and the elastic snap-fit ​​55 is snapped into the first groove 421 to enhance the connection stability between the fixed plate 41 and the extension plate 42.
