Description

Technical Field

[0001] This application relates to the technical field of distribution boxes, and particularly to a comprehensive distribution box facilitating capacitor installation. Background Art

[0002] In the power distribution system, the comprehensive distribution box fixed under the pole-mounted transformer plays a crucial role. As a key node for power distribution and control, it undertakes the task of reasonably distributing the electric energy output by the transformer to each power-consuming terminal. The internal structure of the comprehensive distribution box is complex and is specially divided according to different functions to form multiple independent cavities. Among them, there is a cavity dedicated to installing capacitors. Capacitors play a role in reactive power compensation in the distribution system, can effectively improve the power factor, reduce line losses, and ensure the stable operation of the power system. Therefore, the reliable installation of capacitors is crucial for the normal operation of the comprehensive distribution box and even the entire power system.

[0003] Currently, when installing capacitors in a comprehensive distribution box, a relatively conventional fixing method is usually adopted. Corresponding fixing ears are fixed on the bottom side of the capacitor, and through holes are opened on the fixing ears. When performing the capacitor fixing operation, the staff needs to first place the capacitor inside the cavity dedicated to installing the capacitor. Subsequently, carefully adjust the position of the capacitor so that the through holes on the fixing ears precisely coincide with the screw holes pre-set on the bottom side of the cavity. After alignment, use tools to pass screws through the through holes and slowly screw them into the screw holes. Through the thread fit between the screws and the screw holes, the capacitor is firmly fixed on the bottom side of the cavity to ensure the stability of the capacitor during operation.

[0004] Since the internal space of the cavity of the comprehensive distribution box is relatively narrow itself, when the capacitor is placed inside the cavity, the operable space is further compressed. In such a narrow space, it is extremely difficult for the staff to perform the operations of tightening or loosening the screws, and the use of tools is also greatly restricted. Moreover, during the process of tightening the screws, due to the limited operating space and possible slight shaking, it is very easy for the originally aligned through holes and screw holes to become skewed again. Once skewed, the staff needs to re-adjust the position of the capacitor and perform multiple corrections, which not only consumes a lot of time and energy but also seriously affects the overall fixing efficiency of the capacitor, bringing many troubles to the installation and maintenance work of power equipment. Summary of the Invention

[0005] The purpose of this application is to provide a comprehensive distribution box facilitating capacitor installation, and solve the problem of relatively low overall efficiency in the process of installing the capacitor inside the comprehensive distribution box in the above-mentioned related technologies.

[0006] A comprehensive distribution box facilitating capacitor installation provided by this application adopts the following technical solutions: An integrated distribution box facilitating capacitor installation, comprising a box body and a box door rotatably installed on the box body. A plurality of heat dissipation openings communicating with the installation cavity are formed in the vertical side wall of the box body, and an installation cavity for placing capacitors is arranged in the box body. On the inner walls of the box body opposite to the installation cavity, bearing plates are fixedly arranged along the horizontal direction. Two cross plates are arranged in parallel in the installation cavity, and the two ends of the two cross plates are detachably connected to the upper side surfaces of the two bearing plates respectively. A limiting block is fixedly arranged on the upper side surface of the cross plate, a limiting notch for the bottom of the capacitor to be snapped into and fixed is formed in the upper side surface of the limiting block, and an interface communicating with the limiting notch is formed in the side surface of the opposite limiting blocks on the two cross plates close to each other.

[0007] By adopting the above technical solution, the installation efficiency of capacitors in this integrated distribution box is significantly improved. The limiting blocks are pre-installed on the cross plates, and then the cross plates are installed at the corresponding positions of the bearing plates to complete the "pre-installation" layout. When installing capacitors, the staff does not need to perform complex screw-tightening operations in a narrow space. Just snap the bottom of the capacitor into the limiting notch to complete the preliminary fixation, greatly simplifying the installation process. This not only reduces the operation difficulty but also avoids the problem of the through holes and screw holes being skewed due to limited space, reduces the trouble of repeated calibration, effectively saves time and effort, and solves the problem of the low overall efficiency of installing capacitors into the integrated distribution box.

[0008] Optionally, a fixing plate is arranged above the cross plate. Extension plates facing the inner wall of the installation cavity are fixedly arranged on the opposite side surfaces of the fixing plate. A driving member for driving the extension plate to move up and down is fixedly arranged on the inner wall of the box body. An elastic pad is fixedly arranged on the bottom side of the fixing plate, and the elastic pad can be in contact with the upper side surface of the capacitor installed on the cross plate when the fixing plate moves down.

[0009] By adopting the above technical solution, after the capacitor is preliminarily fixed by snapping its bottom into the limiting notch, the driving member can drive the fixing plate to move down, so that the elastic pad on the bottom side of the fixing plate is in contact with the upper side surface of the capacitor. This design realizes the secondary limitation of the capacitor, effectively reduces the possible shaking of the capacitor during operation, and improves the reliability of capacitor installation. At the same time, the setting of the elastic pad can also play a buffering role, reduce the influence of external vibration on the capacitor, ensure the stable operation of the capacitor in the integrated distribution box, extend the service life of the capacitor, and improve the safety and stability of the entire power distribution system.

[0010] Optionally, the driving member includes an electric cylinder fixedly arranged on the inner wall of the box body along the vertical direction. The telescopic rod of the electric cylinder is vertically downward and fixedly connected to the upper side surface of the extension plate.

[0011] By adopting the above technical solution, the staff can accurately control the telescopic movement of the electric cylinder's telescopic rod, thereby flexibly adjusting the position of the fixed plate, providing sufficient space for capacitor installation. After the installation is completed, the fixed plate can be lowered to make the elastic pad tightly press against the capacitor. Moreover, the electric cylinder operates smoothly and has a stable power output, ensuring a smooth movement process of the fixed plate, guaranteeing the effectiveness of capacitor limiting, and enhancing the reliability of capacitor installation and operation in the comprehensive distribution box.

[0012] Optionally, a sealing plate is slidably arranged on the inner wall of the box body near the heat dissipation port, and an elastic resetting member for driving the sealing plate to move upward is provided; a control member for driving the sealing plate to move downward is arranged on the fixed plate. A sealing port coinciding with the heat dissipation port is formed on the sealing plate. When the sealing plate moves upward, it coincides with the heat dissipation port, and when it moves downward, the heat dissipation port is misaligned and blocked.

[0013] By adopting the above technical solution, in calm outdoor weather, the elastic resetting member drives the sealing plate to move upward, making the sealing port coincide with the heat dissipation port, ensuring normal heat dissipation of the heat dissipation port, maintaining a suitable temperature inside the box body, and guaranteeing the stable operation of components such as capacitors. When strong wind weather occurs outdoors, the control member on the fixed plate can drive the sealing plate to move downward, misaligning the heat dissipation port and the sealing port, thereby effectively blocking the heat dissipation port, reducing the possibility of external dust, impurities, etc. entering the box body through the heat dissipation port, reducing damage to components such as capacitors, improving the adaptability and protection ability of the comprehensive distribution box in different environments, and extending the service life of the equipment.

[0014] Optionally, positioning rods are fixedly arranged along the vertical direction on two opposite vertical side surfaces of the sealing plate. The elastic resetting member includes a first spring, a guiding block fixedly arranged on the inner wall of the box body, and a baffle fixed on the outer periphery of the positioning rod; a guiding hole for the positioning rod to penetrate is formed on the guiding block, the guiding block is located below the baffle, and two ends of the first spring are respectively fixedly connected to the side surfaces of the guiding block and the baffle close to each other.

[0015] By adopting the above technical solution, the elastic resetting member composed of the guiding block, the baffle, and the first spring stores energy when the first spring is compressed after the control member drives the sealing plate to move downward in strong wind weather; when the weather returns to calm, the elastic force of the first spring can push the baffle and the sealing plate to move upward and reset, realizing the automatic opening of the heat dissipation port without manual intervention, improving the automation degree and operation efficiency of the comprehensive distribution box in dealing with different environments.

[0016] Optionally, the control member includes two control rods installed above the fixed plate and two control bumps fixedly arranged on the vertical side surface of the sealing plate. The end of the control rod far from the fixed plate is located above the control bump, and when the control rod moves downward with the fixed plate, it can squeeze the control bump to drive the sealing plate to move downward.

[0017] By adopting the above technical solution, when it is necessary to block the heat dissipation port, the fixing plate moves downward, and the control rod above it moves downward synchronously, thereby exerting a squeezing effect on the control convex block on the vertical side of the blocking plate, pushing the blocking plate downward to make the heat dissipation port and the blocking port misaligned to complete the blocking. At the same time, through the cooperation of the control rod and the control convex block, the acting force can be accurately transmitted to ensure that the blocking plate moves down in place, effectively cope with bad weather such as strong winds, enhance the protection performance of the integrated distribution box, and ensure the stable operation of internal components.

[0018] Optionally, the end of the control rod away from the control convex block is rotatably connected to the upper side of the fixing plate, and a locking member for rotating and adjusting and fixing the control rod is provided above the fixing plate; 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. One end of the control rod away from the fixing plate can rotate on the upper side of the extension plate and insert into the interior of the support notch, and the control rod can rotate on the upper side of the fixing plate.

[0019] By adopting the above technical solution, when it is not necessary to control the downward movement of the blocking 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 strengthened through the control rod; when it is necessary to control the blocking plate, the control rod can be rotated to a suitable position to apply force to the control convex block. The locking member 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 the heat dissipation and protection functions of the integrated distribution box under different working conditions.

[0020] Optionally, a first groove is provided on the upper side of the extension rod, a second groove is provided on the upper side of the fixing plate, and an elastic clamping member capable of being clamped into the first groove and the second groove is provided on the bottom side of the end of the control rod away from the fixing plate.

[0021] By adopting the above technical solution, when one end of the control rod rotates and is clamped into the interior of the support notch, the elastic clamping member is synchronously clamped into the first groove; when one end of the control rod is rotated to the upper side of the fixing plate to adjust the storage and transportation state, the elastic clamping member is synchronously clamped into the second groove; thereby improving the stability of the control rod in the two states.

[0022] Optionally, a receiving sink is provided on the upper side of the fixing plate near the edge of the box door, a locking rod is rotatably connected to the inner wall of the receiving sink, a locking block is fixedly provided on the inner wall of the box door, and a locking notch is provided on the upper side of the locking block; the locking rod can rotate away from the fixing plate to a horizontal state and be unfolded and fixed, and rotate towards the fixing plate to be received and fixed in the receiving sink; a locking plug is fixedly provided on the bottom side of the end of the locking rod away from the fixing plate when it is in the unfolded and fixed state, and the locking plug can move down with the fixing plate and insert into the locking notch in this state.

[0023] 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 the horizontal state for fixing. At this time, the locking insert block on the bottom side of the end of the locking rod 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 accidental opening of the box door and ensuring the safety of the internal components of the integrated distribution box. When the box door does not need to be locked, the locking rod can be rotated towards the fixing plate and stored in the accommodating sink, without occupying extra space and not 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 use safety of the distribution box.

[0024] Optionally, when the control rod can rotate above the accommodating sink, it abuts against and limits the upper side of the locking rod located in the accommodating sink.

[0025] By adopting the above technical solution, when the control rod rotates above the accommodating sink, it can abut against and limit the upper side of the locking rod located in the accommodating sink, avoiding the shaking of the locking rod in the working or non-working state and ensuring the stability of the deployed and stored states.

[0026] In summary, the present application includes the following beneficial technical effects: The integrated distribution box significantly improves the capacitor installation efficiency. The limiting block is pre-installed on the cross plate, and then the cross plate is installed at the corresponding position of the receiving plate to complete the "pre-installation" layout. When installing the capacitor, the staff does not need to perform complex screw-tightening operations in a narrow space. Just snapping the bottom of the capacitor into the limiting notch can complete the preliminary fixation, greatly simplifying the installation process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] Embodiment 1: Reference Figure 1 and Figure 2 A comprehensive distribution box for facilitating capacitor installation comprises a box body 1 and a box door 2 rotatably mounted on the box body 1, a plurality of heat dissipation openings 11 communicating with an installation cavity 13 are provided on a vertical side wall of the box body 1, and a guide cover 12 with an opening facing downward is fixedly arranged on the outer edge of the opening of the heat dissipation opening 11; one side of the box door 2 is hinged to the opening edge of the box body 1, and the other side of the box door 2 is locked and connected to the box body 1 through a conventional lock structure; an installation cavity 13 for placing a capacitor is provided in the box body 1.

[0032] ReferenceFigure 2 and Figure 3 Inside the box body 1, a support assembly 3 is provided. The support assembly 3 includes a receiving plate 31 fixedly arranged on opposite inner walls of the installation cavity 13 along the horizontal direction. Two cross plates 32 are arranged side by side in the installation cavity 13. The two ends of the two cross plates 32 are respectively detachably connected to the upper side surfaces of the two receiving plates 31 through butterfly screws, and the installation position of the cross plate 32 can be slidably adjusted along the length direction of the receiving plate 31 according to the actual situation; On the upper side surface of the cross plate 32, a limiting block 33 is fixedly arranged through screws. Limiting notches 331 for the bottom of the capacitor to be snapped into and fixed are formed on the upper side surfaces of the limiting blocks 33. On the side surfaces of the opposite limiting blocks 33 on the two cross plates 32 that are close to each other, connection ports 332 communicating with the limiting notches 331 are formed.

[0033] The implementation principle of the embodiment of the present application is as follows: When installing the capacitor, the staff can pre-install the limiting block 33 on the cross plate 32 and then install the cross plate 32 at the corresponding position on the receiving plate 31, that is, through "pre-installation", the installation efficiency of the subsequent capacitor is improved, so that when the subsequent capacitor is installed on the limiting block 33, it is not necessary to additionally use screws for fixation, and only the bottom of the capacitor needs to be snapped into the limiting notch 331.

[0034] Embodiment 2: Referring to Figure 4 and Figure 5 In this embodiment of the present application, the difference from Embodiment 1 is that a fixing assembly 4 is provided above the cross plate 32. The fixing assembly 4 includes a fixing plate 41 located above the installed capacitor. On opposite side surfaces of the fixing plate 41, two extension plates 42 integrally formed and facing the inner wall of the installation cavity 13 are provided; on the inner wall of the box body 1, a driving member 43 for driving the extension plate 42 to move up and down is fixedly arranged. The driving member 43 includes an electric cylinder 431 fixedly arranged on the inner wall of the box body 1 along the vertical direction, and the telescopic rod of the electric cylinder 431 is vertically downward and fixedly connected to the upper side surface of the extension plate 42, and an elastic pad 411 made of rubber is fixedly arranged on the bottom side of the fixing plate 41; When installing the capacitor, the driving member 43 drives the fixing plate 41 to move upward to leave enough installation space; after the installation is completed, the driving member 43 drives the fixing plate 41 to move downward. At this time, the elastic pad 411 can be in tight contact with the upper side surface of the capacitor installed on the cross plate 32, so as to further limit the capacitor in the installation cavity 13.

[0035] Referring to Figure 5 and Figure 6, a blocking component 5 is arranged on the inner wall of the box body 1 close to the heat dissipation port 11. The blocking component 5 includes a blocking plate 51 slidably arranged on the vertical inner wall of the box body 1 and an elastic resetting member 52 installed on the inner wall of the box body 1 to drive the blocking plate 51 to move upward; a control member 53 for driving the blocking plate 51 to move downward is arranged on the fixing plate 41, and a blocking port 511 coinciding with the heat dissipation port 11 is formed on the blocking plate 51; In outdoor calm weather, it drives the blocking plate 51 to move upward. At this time, the heat dissipation port 11 coincides with the blocking port 511 to ensure its heat dissipation performance; in outdoor strong winds, it can drive the blocking plate 51 to move downward through the control member 53. At this time, the heat dissipation port 11 is misaligned with the blocking port 511, thereby blocking the heat dissipation port 11 and reducing the possibility of external dust or other impurities entering the box body 1 through the heat dissipation port 11.

[0036] Refer to Figure 7 , positioning rods 512 are fixedly arranged along the vertical direction on the two opposite vertical side surfaces of the blocking plate 51. The elastic resetting member 52 includes a first spring 521, a guiding block 522 fixedly arranged on the inner wall of the box body 1, and a baffle 523 fixed on the outer periphery of the positioning rod 512; a guiding hole for the positioning rod 512 to penetrate is formed on the guiding block 522. The guiding block 522 is located below the baffle 523, and the two ends of the first spring 521 are respectively fixedly connected to the side surfaces of the guiding block 522 and the baffle 523 close to each other.

[0037] Refer to Figure 5 and Figure 7 , the control member 53 includes two control rods 531 installed above the fixing plate 41 and a control convex block 532 fixedly arranged on the vertical side surface of the blocking plate 51. The end of the control rod 531 far from the fixing plate 41 is located above the control convex block 532. When the control rod 531 moves downward with the fixing plate 41, it can squeeze the control convex block 532 to drive the blocking plate 51 to move downward; In outdoor strong winds, the driving member 43 drives the fixing plate 41 to move downward. When the elastic pad 411 on the lower side of the fixing plate 41 abuts against the upper side of the capacitor, it synchronously drives the control rod 531 to squeeze the control convex block 532, thereby driving the blocking plate 51 to move downward, making the heat dissipation port 11 misaligned with the blocking port 511; in this way, both the installation stability of the capacitor in strong wind weather and the protection performance in this weather can be improved.

[0038] Refer to Figure 7 and Figure 8 , the end of the control rod 531 far from the control convex block 532 is rotatably connected to the upper side surface of the fixing plate 41. A locking member 54 for rotating and adjusting and fixing the control rod 531 is arranged above the fixing plate 41; the staff can adjust the installation angle of the control rod 531 by controlling the locking member 54; The upper side of the fixing plate 41 is provided with a locking screw hole, and the end of the control rod 531 is provided with a locking through hole. The locking member 54 is a locking bolt 541 that passes through the locking through hole and is screwed into the locking screw hole, and the locking bolt 541 is a butterfly bolt that can be manually tightened or loosened. When the fixing plate 41, the control rod 531, and the extension plate 42 are transported as a whole part, the control rod 531 can be rotated to the upper side of the fixing plate 41, reducing the overall volume during packaging and lowering the transportation cost.

[0039] Refer to Figure 9 , a support block 44 is fixedly arranged 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 applied environment is good and it is not necessary to control the downward movement of the plugging plate 51, the end of the control rod 531 away from the fixing plate 41 can be rotated to the upper side of the extension plate 42 and inserted into the interior of the support notch 441. At this time, the control rod 531 can enhance the connection stability between the fixing plate 41 and the extension plate 42.

[0040] Refer to Figure 8 , Figure 9 and Figure 10 , a first groove 421 is provided on the upper side of the extension rod. Among them, a second groove 412 is provided on the upper side of the fixing plate 41, and an elastic clamping member 55 capable of being clamped into the first groove 421 and the second groove 412 is arranged on the bottom side of the end of the control rod 531 away from the fixing plate 41; The elastic clamping member 55 includes a compression spring 551 and an arc-shaped convex block 552. A placement groove 5311 for placing the compression spring 551 and the arc-shaped convex block 552 is provided on the extension rod. The compression spring 551 squeezes one side of the arc-shaped convex block 552, causing a part of the arc-shaped convex block 552 to protrude from the opening of the placement groove 5311, and the protruding part of the arc-shaped convex block 552 is an arc surface, and the corresponding protrusion of the arc surface is a minor arc; When one end of the control rod 531 is rotated and clamped into the interior of the support notch 441, the elastic clamping member 55 is synchronously clamped into the first groove 421; when one end of the control rod 531 is rotated to the upper side of the fixing plate 41 for adjustment and storage and transportation state, the elastic clamping member 55 is synchronously clamped into the second groove 412; thereby improving the stability of the control rod 531 in two states.

[0041] Refer to Figure 9 and Figure 11 , a receiving sink 413 is provided on the upper side of the fixing plate 41 near the edge of the box door 2. Among them, a locking assembly 6 is provided on the inner wall of the receiving sink 413. The locking assembly 6 includes a locking rod 61 whose one end is rotatably connected to the inner wall of the receiving sink 413. A locking block 21 is fixedly arranged on the inner wall of the box door 2, and a locking notch 211 is provided on the upper side of the locking block 21; The locking lever 61 can rotate away from the fixed plate 41 to the horizontal state for deployment and fixation, and rotate towards the fixed plate 41 to be received and fixed in the receiving sink 413; a locking insert block 62 is fixedly provided on the bottom side of the end of the locking lever 61 away from the fixed plate 41 when it is in the deployed and fixed state; when the locking lever 61 is not needed for locking protection, the locking lever 61 can be rotated into the receiving sink 413 for storage and fixation; When the locking lever 61 is needed for locking protection, the locking lever 61 can be rotated out of the receiving sink 413 to the horizontal state and fixed. Then, when the driving member 43 drives the fixed plate 41 to move downward to abut against the upper side of the capacitor, the locking insert block 62 can move downward with the fixed plate 41 and be inserted into the locking notch 211 to further lock the box door 2, thereby reducing the possibility of unauthorized persons opening the box door 2.

[0042] Referring to Figure 9 and Figure 11 , when the control lever 531 can rotate above the receiving sink 413, it abuts against and limits the upper side of the locking lever 61 in the receiving sink 413; that is, when the locking lever 61 is deployed or stored in the horizontal state, the control lever 531 in the horizontal state can be limited and fixed by rotating and adjusting the control lever 531.

[0043] The implementation principle of the embodiment of the present application is as follows: When installing the capacitor, the electric cylinder 431 drives the fixed plate 41 to move upward to provide space; after installation, the electric cylinder 431 makes the fixed plate 41 move downward, and the elastic pad 411 on its bottom side abuts tightly against the capacitor, realizing further limitation of the capacitor in the installation cavity 13 and ensuring the stability of the capacitor; In outdoor calm weather, the elastic reset member 52 makes the blocking plate 51 move upward, and the heat dissipation port 11 coincides with the blocking port 511 to ensure heat dissipation; in strong winds, the driving member 43 drives the fixed plate 41 to move downward, the control lever 531 presses the control convex block 532, driving the blocking plate 51 to move downward, and the heat dissipation port 11 is misaligned with the blocking port 511 to block the heat dissipation port 11, reducing the entry of dust and impurities; When the fixed plate 41, the extension plate 42, and the control lever 531 are transported as a whole as components, the control lever 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 cost; when the environment is good, the control lever 531 is rotated to the support notch 441 of the extension plate 42, and the elastic clamping member 55 is snapped into the first groove 421 to enhance the connection stability between the fixed plate 41 and the extension plate 42.
