Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a pole-mounted integrated distribution box with compensation. Background Technology

[0002] With the development trend of smart grid construction and refined operation and maintenance of distribution networks, pole-mounted integrated distribution boxes with compensation units have become one of the core devices in outdoor power distribution systems. This equipment integrates multiple functions such as distribution control, power metering, and reactive power compensation. It can monitor line load changes in real time and automatically switch capacitor compensation modules to balance reactive power, effectively improving the power factor and power quality of the grid and reducing line losses. Installed on utility poles in urban and rural roads, commercial areas, and other scenarios, it can adapt to complex outdoor operating environments, meet the integrated and intelligent application requirements of smart grids for distribution terminal equipment, and is a key carrier for achieving efficient operation and maintenance of distribution networks.

[0003] Existing outdoor pole-mounted distribution boxes with compensation units mainly consist of a box body and a rotating door connected to the front. The box interior is divided into functional chambers such as a switch compartment, metering compartment, and capacitor compensation compartment by partitions. Two wiring ports are pre-installed on the bottom of the box body for cable connection. The installation process is straightforward: a crossarm is first erected horizontally between two utility poles, and then the top of the distribution box is fixed to the bottom of the crossarm with screws. Subsequently, one end of the overhead cable from the utility pole is lowered and introduced into the box body through the wiring ports to complete the wiring operation. After installation, the bottom of this type of distribution box is typically positioned 1.2-1.5 meters above the ground, integrating power distribution, metering, and compensation functions while ensuring ease of installation and operation.

[0004] When the aforementioned distribution boxes are used in densely populated areas such as urban areas, the bottom of the distribution box is only 1.2-1.5m from the ground, and the cables connected to the box need to hang down from the overhead position and be laid close to the vertical outer side of the distribution box. This may cause elderly people or children with weak safety awareness to accidentally touch the hanging cables during peak hours, resulting in electric shock risk. There is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a pole-mounted integrated distribution box with compensation to solve the problem in the above-mentioned related technologies that the drooping cables of the distribution box are easily touched by the elderly or children in densely populated urban areas, which may cause electric shock risks.

[0006] The technical solution for the pole-mounted integrated distribution box with compensation provided in this application is as follows: A pole-mounted integrated distribution box with compensation includes a box body and a door rotatably installed on the front side of the box body. The left and right sides of the box body are provided with several heat dissipation vents, the bottom surface is provided with a wiring port, and the top surface is fixed with several lifting rings. The left and right sides of the box body are detachably installed with protective plates in a vertical protective state. The protective plates have vertical clearance notches on the side facing the box body for hanging cables to pass through.

[0007] By adopting the above technical solution, when the protective plate is in vertical protection mode, it can limit drooping cables within the clearance gap, forming a physical isolation barrier. This effectively prevents accidental contact by the elderly, children, and other people with weak safety awareness, thus avoiding the risk of electric shock at the source and meeting the safety needs of outdoor scenarios with high pedestrian traffic. Simultaneously, the clearance gap can precisely accommodate drooping cables without affecting normal cable laying and wiring operations. Furthermore, the protective plate is detachable, facilitating cable removal and installation, as well as the disassembly and storage of the protective plate during equipment installation and maintenance. The protective plate also helps to cover the side ventilation openings of the enclosure, reducing the intrusion of external impurities. It provides protection for both cables and internal components, with a simple and practical overall structure that does not alter the original installation process or core functions of the equipment.

[0008] Optionally, the bottom left and right edges of the protective plate are rotatably connected to a central rod rotatably connected to the bottom surface of the protective plate, and locking elements are provided on the left and right outer surfaces of the box. The two protective plates can be rotated downwards to a movable state that abuts against the bottom surface of the box. A movable rod is rotatably installed on the inner wall of the clearance notch, and an installation notch is provided. A movable wheel is fixed on the outer periphery of the end of the movable rod away from the protective plate. When the protective plate is in the protective state, the movable rod rotates to a vertical upward state and is limited by the locking element. At this time, the movable wheel rotates into the installation notch. When the protective plate is in the movable state, the movable rod rotates to a horizontal state in the direction away from the installation notch and is limited by the locking element. At this time, the bottom surface of the movable wheel protrudes from the bottom surface of the protective plate.

[0009] By adopting the above technical solution, the protective plate can be switched between protective and movable states via the central rod. In the protective state, the movable rod is vertically retracted into the installation notch and locked in place, without affecting cable protection or equipment operation. When switching to the movable state, the protective plate folds down to fit against the bottom of the enclosure, the movable rod rotates out to a horizontal position and locks, and the protruding movable wheels provide support. The movable wheels allow for easy short-distance transport of the equipment without relying on large hoisting equipment, reducing handling costs and difficulty. The locking mechanism ensures the stability of the components in both states, the retractable design of the movable wheels does not interfere with outdoor installation, and the overall structure is compact.

[0010] Optionally, the locking component includes a locking plate disposed horizontally on the left and right vertical outer surfaces of the housing, a positioning rod disposed vertically on the inner wall of the housing, and an elastic pressing component disposed on the inner wall of the housing to drive the positioning rod downward. The locking plate has a locking notch, and a locking protrusion is fixedly disposed on the bottom surface of the locking plate. The left and right sides of the housing have guide grooves, and a connecting rod is fixedly disposed on the outer periphery of the positioning rod, which passes through the guide groove and is fixedly connected to the locking plate. A locking groove is disposed on the end face of the moving rod away from the protective plate, and the locking protrusion can move downward and insert into the locking groove when both the protective plate and the moving rod are in a vertical state.

[0011] By adopting the above technical solution, the positioning rod is moved downwards by an elastic compression component. This, along with the connecting rod and locking plate, allows the locking protrusion to precisely insert into the locking groove of the moving rod, firmly fixing the vertically positioned moving rod and ensuring stable protection. The locking notch on the locking plate can accommodate a hanging cable, which, combined with the clearance notch on the aforementioned protective plate, provides double cable limiting. The overall linkage structure requires no additional fixing operation; unlocking simply requires moving the locking plate upwards, making operation convenient and balancing limiting reliability with efficient maintenance, suitable for complex outdoor working conditions. When moving using the casters, the locking plate can also act as a "traction handle" to facilitate pulling the enclosure.

[0012] Optionally, an elastic pad is fixed on the inner wall of the locking notch.

[0013] By adopting the above technical solution, the elastic pad on the inner wall of the locking notch can buffer cable friction and avoid wear.

[0014] Optionally, the locking protrusion has a first inclined surface at the outer edge away from the locking plate.

[0015] By adopting the above technical solution, the first inclined surface of the outer edge of the locking protrusion can be guided to smoothly insert into the locking groove, thereby improving the efficiency of state switching.

[0016] Optionally, the elastic compression member includes a first spring in a compressed state, a guide block fixed to the inner wall of the box, and a baffle fixed to the outer periphery of the positioning rod. The baffle is located below the guide block, and 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.

[0017] By adopting the above technical solution, the first spring in the compressed state provides continuous downward pressure through the guide block and the baffle, driving the positioning rod to lock the plate. This, combined with the first inclined surface of the locking protrusion, achieves smooth limiting, and works in conjunction with the elastic pad to ensure stable locking while protecting the cable, thus balancing convenience and safety.

[0018] Optionally, the inner wall of the housing is provided with a sealing plate that is fixedly connected to the two positioning rods on the same side on opposite sides. The sealing plate is provided with a sealing hole. The sealing hole coincides with the heat dissipation vent when the locking protrusion is inserted into the locking groove, and is misaligned with the heat dissipation vent when the limiting rod is inserted into the limiting slot.

[0019] By adopting the above technical solution, the sealing plate and positioning rod are linked to achieve intelligent switching of the sealing hole according to the equipment's operating conditions. In the protective state, it coincides with the heat dissipation vent to ensure heat dissipation; in the moving state, it is offset and blocks the vent to reduce the intrusion of impurities. Combined with elastic compression components and a locking structure, it balances heat dissipation efficiency and enclosure protection, improving the equipment's outdoor adaptability.

[0020] Optionally, a limiting through hole is provided on the bottom surface of the housing, and a limiting rod is coaxially fixed on the lower end surface of the positioning rod, passing through the limiting through hole. When the protective plate is in the moving state and the moving wheel protrudes from the bottom surface of the protective plate, a limiting slot is provided on the top surface of the moving rod that coincides with the limiting through hole. When the protective plate is in the moving state, the elastic pressing member drives the limiting rod to move down and insert into the limiting slot. When the locking plate is moved up by an external force, it drives the limiting rod to disengage from the limiting slot.

[0021] By adopting the above technical solution, after the protective plate switches to the moving state, the elastic compression component drives the limit rod to move down and insert into the slot, firmly fixing the moving rod and the protective plate, ensuring structural stability during transportation. Unlocking only requires moving the locking plate upwards to release the limit rod, making the operation convenient and requiring no additional tools. This structure, in conjunction with components such as the sealing plate and locking protrusions, ensures consistent switching between the two operating states of the equipment. This enhances the reliability of state locking, maintains the overall operating logic, balances mobile safety and operational efficiency, and provides natural contextual function transitions, improving the overall adaptability of the equipment.

[0022] Optionally, a second inclined surface is provided at the lower outer edge of the limiting rod.

[0023] By adopting the above technical solution, the second inclined surface at the lower end of the limiting rod can guide it to smoothly insert into the limiting slot, thereby improving the locking efficiency in the moving state.

[0024] Optionally, a third bevel is provided at the opening edge of the limiting slot.

[0025] By adopting the above technical solution, the third inclined surface of the limiting slot opening cooperates with the second inclined surface of the limiting rod, and the limiting rod is accurately and smoothly inserted through dual guidance, further improving the locking efficiency.

[0026] In summary, this application includes the following beneficial technical effects: In this application, when the protective plate is in a vertical protective state, it can confine drooping cables within the clearance gap, forming a physical isolation barrier. This effectively prevents accidental contact by the elderly, children, and other people with weak safety awareness, thus avoiding the risk of electric shock at the source and meeting the safety needs of outdoor scenarios with high pedestrian traffic. Simultaneously, the clearance gap can precisely accommodate drooping cables without affecting normal cable laying and wiring operations. Furthermore, the protective plate is detachable, facilitating cable removal and installation during equipment installation and maintenance, as well as the disassembly and storage of the protective plate.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0030] Reference Figure 1 and Figure 2 A pole-mounted integrated distribution box with compensation includes a box body 1, a box door 2 rotatably installed on the front side of the box body 1, several heat dissipation vents 11 on the left and right sides of the box body 1, a wiring port 12 on the bottom surface, and two lifting rings 13 fixed on the top surface for easy subsequent hoisting; protective components 3 are provided on the left and right sides of the box body 1. The protective component 3 includes a protective plate 31 that is detachably installed on the left and right sides of the box 1 in the vertical direction. At this time, the protective plate 31 is in a protective state, and a clearance notch 311 is provided on the side of the protective plate 31 facing the box 1 in the vertical direction. When the integrated distribution box is installed and applied, the hanging cables on the left and right sides of the box 1 can be placed in the clearance notch 311, and the hanging cables are protected by the protective plate 31.

[0031] Reference Figure 3 , Figure 4 and Figure 5 The bottom left and right edges of the protective plate 31 are rotatably connected to the intermediate rod 32, which is rotatably connected to the bottom of the protective plate 31. Locking parts 4 are provided on the left and right outer sides of the box body 1. The two protective plates 31 can be rotated downwards to a moving state that abuts against the bottom of the box body 1. A moving rod 33 is rotatably installed on the inner wall of the clearance notch 311, and an installation notch 312 is provided. A moving wheel 34 is fixed on the outer periphery of the end of the moving rod 33 away from the protective plate 31. When the protective plate 31 is in the protected state (i.e., when the distribution box is installed), the moving rod 33 rotates to the vertical upward state and is limited by the locking member 4, and the moving wheel 34 rotates into the installation notch 312 at this time; when the protective plate 31 is in the moving state (i.e., when the distribution box is moved a short distance), the moving rod 33 rotates to the horizontal state in the direction away from the installation notch 312 and is limited by the locking member 4, and the bottom surface of the moving wheel 34 protrudes from the bottom surface of the protective plate 31 at this time.

[0032] Reference Figure 5 , Figure 6 and Figure 7 The locking component 4 includes a locking plate 41 disposed horizontally on the left and right vertical outer surfaces of the box 1, a positioning rod 42 disposed vertically on the inner wall of the box 1, and an elastic pressing component 43 disposed on the inner wall of the box 1 to drive the positioning rod 42 to move downward. A locking protrusion 44 is fixedly disposed on the bottom surface of the locking plate 41, and a first inclined surface 441 is disposed on the outer edge of the locking protrusion 44 away from the locking plate 41. The locking plate 41 has a locking notch 411, and the inner wall of the locking notch 411 is fixed with an elastic pad 412 made of rubber. The left and right sides of the box 1 have guide grooves 14, and the outer periphery of the positioning rod 42 is fixed with a connecting rod 421 that passes through the guide groove 14 and is fixedly connected to the locking plate 41. The end face of the moving rod 33 away from the protective plate 31 has a locking groove 331. When both the protective plate 31 and the moving rod 33 are in a vertical position (i.e., when the distribution box is installed), the locking protrusion 44 moves downward and inserts into the locking groove 331 under the action of the elastic pressing member 43. At this time, the hanging cable passes through the locking notch 411 and is inserted into the clearance notch 311. At the same time, the elastic pad 412 is used to reduce the possibility of wear on the hanging cable.

[0033] Reference Figure 6 and Figure 8 The elastic compression member 43 includes a first spring 431 in a compressed state, a guide block 432 fixed to the inner wall of the housing 1, and a baffle 433 fixed to the outer periphery of the positioning rod 42. The baffle 433 is located below the guide block 432. The two ends of the first spring 431 are fixedly connected to the sides of the guide block 432 and the baffle 433 that are close to each other. The inner wall of the housing 1 is provided with a sealing plate 45 on two opposite sides that are fixedly connected to the sides of the two positioning rods 42 on the same side that are close to each other. The sealing plate 45 is provided with a sealing hole 451. When the locking protrusion 44 is inserted into the locking groove 331 (i.e., the distribution box installation application), the sealing hole 451 coincides with the heat dissipation vent 11, ensuring the heat dissipation performance of the distribution box; when the limit rod 46 is inserted into the limit slot 332 (i.e., the distribution box moves a short distance), the sealing hole 451 is misaligned with the heat dissipation vent 11, reducing the possibility of external impurities entering the box 1 from the heat dissipation vent 11.

[0034] Reference Figure 9 and Figure 10 A limiting through hole 15 is provided on the bottom surface of the housing 1. A limiting rod 46 that passes through the limiting through hole 15 is coaxially fixed on the lower end surface of the positioning rod 42. A second inclined surface 461 is provided at the lower outer edge of the limiting rod 46. When the protective plate 31 is in the moving state and the moving wheel 34 protrudes from the bottom surface of the protective plate 31, a limiting slot 332 that coincides with the limiting through hole 15 is provided on the top surface of the moving rod 33. A third inclined surface 3321 is provided at the opening edge of the limiting slot 332. When the protective plate 31 is in a moving state (that is, the distribution box moves a short distance), the elastic pressing member 43 drives the limiting rod 46 to move down and insert into the limiting slot 332, thereby locking the state of the moving rod 33 and the protective plate 31 at this time; when it is necessary to release the lock of the moving state, an external force is applied to the locking plate 41 to move it up, thereby driving the limiting rod 46 to come out of the limiting slot 332.

[0035] The implementation principle of this application embodiment is as follows: During installation, the protective plate 31 is vertically and detachably mounted on both sides of the housing 1 for protection. The hanging cable passes sequentially through the clearance notch 311 and the locking notch 411, with the elastic pad 412 preventing cable wear. The moving rod 33 is vertically retracted into the mounting notch 312, and the first spring 431 pushes the positioning rod 42 downwards, causing the locking protrusion 44 to insert into the locking groove 331, completing the limiting position. At this time, the sealing hole 451 coincides with the heat dissipation vent 11, ensuring heat dissipation performance.

[0036] During short-distance movement, the locking plate 41 is moved upwards to disengage the locking protrusion 44, and the protective plate 31 is rotated downwards to abut against the bottom surface of the housing 1. Then, the moving rod 33 is rotated to a horizontal position, and the elastic pressing member 43 drives the limiting rod 46 downwards, inserting it into the limiting slot 332 to complete the locking. The moving wheel 34 protrudes to facilitate movement. At this time, the sealing hole 451 is misaligned with the heat dissipation vent 11, reducing the entry of external impurities and balancing ease of movement with the protection of the housing 1.

[0037] When switching states, first use the hoisting equipment to keep the bottom of the box 1 at a certain height from the ground through the lifting ring 13, and then use external force to lift the locking plate 41 to drive the positioning rod 42 and the limit rod 46 to move. After unlocking, adjust the position of the components and rotate the protective plate 31 to adjust its state.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
