Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to an energy-saving integrated distribution box. Background Technology

[0002] In the construction and operation of smart grids, energy-saving integrated distribution boxes, as core terminal equipment of the power distribution system, are widely used in outdoor pole-mounted power distribution scenarios. Their ease of installation and use, as well as their stability, directly affect the overall operating efficiency and maintenance experience of the power grid. Outdoor pole-mounted distribution boxes, as an important application form of energy-saving integrated distribution boxes, need to adapt to the complex outdoor natural environment. They must achieve efficient power distribution and transmission while possessing good protective performance to resist the intrusion of rainwater, dust, and other external impurities. Simultaneously, they must ensure the standardization of installation and operation and the safety of use. They are a key facility for ensuring a stable power supply in outdoor power distribution.

[0003] Existing outdoor pole-mounted distribution boxes mainly consist of a box body and a door rotatably connected to the front of the box body. To balance heat dissipation and wiring requirements, several heat dissipation vents and wiring ports are provided on the left and right vertical side walls of the box body. To improve protection, protective tubes with downward-bent openings are fixed to the outer edges of the wiring ports, effectively preventing rainwater and dust from entering the wiring area and avoiding faults such as poor contact. In terms of installation, this type of distribution box generally uses a screw connection method to fix the top surface of the box body to the top surface of the crossarm erected on the pole. The installation height is set at 1.5 meters or more above the ground, which not only meets the convenience of on-site operation for maintenance personnel, but also prevents unauthorized personnel from accidentally touching it to a certain extent, reducing the probability of safety accidents.

[0004] Among the aforementioned technologies, this type of distribution box is relatively heavy due to its structural design and material selection. When it needs to be moved short distances for power grid maintenance or relocation, multiple workers are often required to move it, which not only consumes a lot of manpower and time but also results in low maintenance efficiency. Furthermore, the lack of specialized protective and load-bearing structures during transportation makes the outer edge of the box prone to collisions and scratches with surrounding objects, causing problems such as box deformation and paint damage. This not only affects the appearance of the equipment but also reduces the corrosion resistance and protection performance of the box, significantly shortening the overall service life of the distribution box, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an energy-saving integrated distribution box to solve the problems of outdoor pole-mounted distribution boxes in the above-mentioned related technologies, which are heavy, require multiple people to move over short distances, are time-consuming and labor-intensive, and are prone to being bumped and damaged during handling, thus affecting their service life.

[0006] The energy-saving integrated distribution box provided in this application adopts the following technical solution: An energy-saving integrated distribution box includes a box body and a door rotatably mounted on the front side of the box body. Several ventilation openings are provided on the left and right vertical side walls of the box body. Support plates are horizontally fixed along the left and right edges of the bottom surface of the box body. Connecting rods are rotatably connected to the bottom surfaces of both ends of the support plates, with the rotation surfaces of the connecting rods parallel to the front side of the box body. An adjustable-length protective rod is vertically fixed to the outer periphery of the end face of the connecting rod away from the support plate. A movable wheel is fixed to the side of the connecting rod away from the protective rod. During transportation of the distribution box, the protective rod can rotate with the connecting rod to a vertically upward-facing protective state, protecting the vertical edges of the box body. The movable wheel is located on the side of the connecting rod facing the ground at this time. During installation of the distribution box, the protective rod can rotate with the connecting rod to a vertically downward-facing supporting state, with the movable wheel located on the sides where the two support plates are close to each other.

[0007] By adopting the above technical solution, a support plate, connecting rod, adjustable protective rod, and casters are installed on the bottom surface of the enclosure, achieving integrated switching between protection, movement, and support functions. During transportation, the protective rod can be rotated vertically upwards to effectively protect the vertical edges of the enclosure, preventing bumps and knocks during handling. The casters assist in the rapid short-distance movement of the enclosure, eliminating the need for multiple personnel to coordinate the handling, significantly saving manpower and resources and improving maintenance efficiency. During installation, the protective rod can be rotated vertically downwards and adjusted to rest against the ground, improving installation stability. At the same time, the casters can be stored between the two support plates to prevent exposed damage and extend the service life of the equipment.

[0008] Optionally, the bottom edge of the housing is provided with locking plates, the bottom surface is provided with elastic elements that drive the two locking plates to slide in a direction away from each other, and the outside is provided with control elements that drive the two locking plates to slide back and forth in a direction close to each other; the top surfaces of the ends of the two locking plates that are far apart from each other are rotatably connected with locking rods, and the rotating surface of the locking rods is parallel to the front side of the housing; the outer periphery of the end of the locking rod that is far apart from the locking plate is fixed with a locking insert facing the housing, and the outer side surfaces of the two protective rods on the same side that are far apart from each other are provided with locking slots; when the protective rods are in the protective state, the two locking rods can rotate to a coaxial state in a direction away from each other, and the control elements can slide the two locking plates towards each other at this time, and the locking inserts can be inserted into the locking slots at this time.

[0009] By adopting the above technical solution, the protective rod is locked in place when it is in protective mode. Through the cooperation of the locking plate, elastic element, control element, locking rod, and locking block, after the locking rod is rotated to a coaxial state, the control element drives the locking plate to slide in opposite directions, so that the locking block is inserted into the locking slot of the protective rod, effectively fixing the position of the protective rod and preventing it from shifting due to shaking during transportation, thus ensuring the protective effect. At the same time, it improves the overall stability of the box when it moves, avoiding damage to the box caused by impact due to protective failure.

[0010] Optionally, the front and rear lower edges of the housing are provided with first slots; when the protective rod is in the supported state, the two locking rods can rotate to a coaxial state facing each other, the control component can slide the two locking plates facing each other so that the locking block can be inserted into the first slot, and the elastic component can also make the two locking plates slide back to back, using the two locking rods and locking plates to limit the upper part of the erected maintenance ladder.

[0011] By adopting the above technical solution, during installation, the locking rods rotate in opposite directions and are inserted into the first slot of the housing through the locking block, which can fix the position of the locking plate and prevent it from shaking and affecting the overall stability of the equipment. During maintenance, the elastic element drives the locking plate to slide in opposite directions, and the locking rods and locking plates together limit the upper part of the maintenance ladder to prevent the ladder from sliding and tipping over, providing safety for maintenance personnel. There is no need to add an additional limiting structure, which simplifies the design and reduces costs.

[0012] Optionally, a first inclined surface is provided at the outer edge of the locking block.

[0013] By adopting the above technical solution, the first inclined surface can play a guiding role during the insertion process, guiding the locking block to quickly align with the slot opening, so that it can be inserted smoothly without precise alignment, reducing the difficulty of operation and improving the efficiency of operation.

[0014] Optionally, the elastic element is an elastic telescopic rod whose two ends are respectively fixedly connected to the two locking plates close to each other on the sides, and the elastic telescopic rod has the property of elastic elongation.

[0015] By adopting the above technical solution, using an elastic telescopic rod with elastic elongation properties as the elastic element, the structure is simple, practical, and adaptable. Its two ends are fixed to two locking plates, naturally causing the two locking plates to slide away from each other without the need for additional power, simplifying the control process. In scenarios such as transportation unlocking and maintenance limiting, the elastic telescopic rod can flexibly adapt to the sliding needs of the locking plates through compression and extension. Its elastic recovery performance is stable, continuously providing a uniform elastic force to the locking plates, ensuring smooth operation of the locking structure. At the same time, the elastic telescopic rod is a conventional structure, easy to procure, install, and maintain, reducing equipment manufacturing costs.

[0016] Optionally, the control component includes four control rods, one end of which is rotatably connected to the left and right edges of the sides of the two locking plates that are close to each other. The other ends of the two control rods on the same side of the two locking plates are connected to a control rope. A control hole for the control rope to pass through is opened in the middle of the support plate in the horizontal direction. Several protrusions are fixed along their own length on the sides of the two guard rods that are close to each other on the same side. An adjustment rod is provided in the horizontal direction between the two guard rods on the same side, with the middle part fixedly connected to the other end of the control rope. Adjustment blocks are fixed at both ends of the adjustment rod. Adjustment slots for the adjustment blocks to be inserted are opened on the sides of the two protrusions at the same height that are close to each other.

[0017] By adopting the above technical solution, and utilizing the cooperation of the control rod, control rope, adjustment rod, protrusion, and adjustment slot, simply moving the adjustment rod to insert the adjustment block into the adjustment slot at different heights allows the control rope to be pulled to drive the locking plate to slide in opposite directions. This is simple, time-saving, and labor-saving, and suitable for outdoor field operation needs. The control hole can limit and guide the control rope, preventing it from tangling or deviating, and ensuring the smoothness of the control action. At the same time, the overall structure is linked with the protective rod, eliminating the need for additional control mechanisms and saving installation space.

[0018] Optionally, a second inclined surface is provided at the outer edge of the adjusting block.

[0019] By adopting the above technical solution, the second inclined surface can guide the adjustment block to slide quickly into the adjustment slot, reducing the difficulty of alignment and improving the efficiency of adjustment operation.

[0020] Optionally, a third bevel is provided at the opening edge of the adjustment slot.

[0021] By adopting the above technical solution, the third bevel can expand the guiding range of the slot opening. Even if there is a slight misalignment of the adjusting plug, it can be quickly aligned with the slot through the guiding effect of the double bevel, achieving precise embedding.

[0022] Optionally, the outer periphery of the adjusting plug is provided with an elastic snap-fit ​​component, and the inner wall of the adjusting slot is provided with a positioning groove for the elastic snap-fit ​​component to snap into.

[0023] By adopting the above technical solution, a flexible locking component is incorporated into the adjusting block, and a positioning groove is created on the inner wall of the adjusting slot, effectively improving the installation stability of the adjusting rod. After the adjusting block is inserted into the slot, the flexible locking component engages with the positioning groove, firmly fixing the adjusting rod in its current position and preventing displacement due to equipment vibration or external force, thus ensuring the stability of the locking plate. Simultaneously, the flexible locking component is flexible and retractable; during disassembly, only slight force is required to release the component from the groove, without affecting the convenience of the adjustment operation. The structure is simple and the locking is reliable, improving the overall stability of the control components.

[0024] Optionally, the elastic snap-fit ​​component includes a compression spring and an arc-shaped protrusion. The adjusting insert has a placement groove for the compression spring and the arc-shaped protrusion to be placed in. The compression spring presses one side of the arc-shaped protrusion so that a part of the arc-shaped protrusion protrudes from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion is an arc surface, and the arc length corresponding to this arc is a minor arc.

[0025] By adopting the above technical solution, the compression spring continuously applies a squeezing force to the arc-shaped protrusion, causing it to protrude stably and lock into the positioning groove, ensuring a firm locking effect and effectively preventing the adjustment block from shifting. The protruding part of the arc-shaped protrusion has a slightly curved surface, which not only ensures the stability of the locking but also allows the protrusion to be smoothly compressed and released from the groove during disassembly through the guiding effect of the curved surface, avoiding jamming. The overall structure is compact and can be embedded inside the adjustment block without occupying extra space. The compression spring and the arc-shaped protrusion are wear-resistant and have stable elasticity, which can adapt to complex outdoor environments and ensure long-term reliable use of the locking structure.

[0026] In summary, this application includes the following beneficial technical effects: In this application, a support plate, connecting rod, adjustable protective rod, and casters are installed on the bottom surface of the enclosure, realizing the integrated switching of protection, movement, and support functions. During transportation, the protective rod can be rotated to face vertically upwards to effectively protect the vertical edges of the enclosure and avoid bumps during handling. The casters assist in the rapid short-distance movement of the enclosure, eliminating the need for multiple personnel to coordinate the handling, greatly saving manpower and resources and improving operation and maintenance efficiency. During installation, the protective rod can be rotated to face vertically downwards and adjusted to rest against the ground to improve installation stability. At the same time, the casters can be stored between the two support plates to avoid exposure damage and extend the service life of the equipment. Attached Figure Description

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

[0030] Reference Figure 1 and Figure 2 An energy-saving integrated distribution box includes a box body 1 and a door 2 rotatably installed on the front side of the box body 1. Several heat dissipation vents 11 are provided on the left and right vertical side walls of the box body 1. A support assembly 3 is provided below the box body 1. The support assembly 3 includes a support plate 31 fixed horizontally at the left and right edges of the bottom surface of the box body 1. Connecting rods 32 are rotatably connected to the bottom surfaces of both ends of the support plate 31. The rotating surface of the connecting rod 32 is parallel to the front side of the box body 1. An adjustable length protective rod 33 is vertically fixed on the outer periphery of the end face of the connecting rod 32 away from the support plate 31, and a movable wheel 34 is fixed on the side of the connecting rod 32 away from the protective rod 33; the protective rod 33 is a conventional telescopic rod whose adjusted length can be fixed by screws. This is a conventional telescopic structure, which will not be described in detail here. During the transportation of the distribution box, the protective rod 33 can rotate with the connecting rod 32 to a vertically upward protective state that protects the vertical edge of the box 1. The moving wheel 34 is located on the side of the connecting rod 32 facing the ground. At this time, the four protective rods 33 are used to protect the four vertical edges of the box 1, and the moving wheel 34 is used to assist the box 1 in making short-distance rapid movements. During the installation of the distribution box, the protective rod 33 can rotate to a vertically downward support state with the connecting rod 32. Then, the length of the protective rod 33 is adjusted and fixed so that the lower end of the protective rod 33 abuts against the ground, improving the installation stability of the distribution box. At this time, the moving wheel 34 is located on the side where the two support plates 31 are close to each other, which better accommodates the moving wheel 34.

[0031] Reference Figure 3 , Figure 4 and Figure 5 The lower part of the box body 1 is provided with a locking assembly 4 for limiting the protective rod 33 in the protective state; wherein the locking assembly 4 includes two locking plates 41 that slide on the front and rear edges of the bottom of the box body 1, an elastic element 42 provided on the bottom surface of the box body 1 for driving the two locking plates 41 to slide in a direction away from each other, and a control element 43 provided outside the box body 1 for driving the two locking plates 41 to slide back and forth in a direction close to each other. Two locking plates 41 are rotatably connected to the top surfaces of their ends that are far apart from each other, with adjustable locking rods 44. The rotating surface of the locking rods 44 is parallel to the front side of the housing 1. A locking insert 441 facing the housing 1 is fixed on the outer periphery of the end of the locking rod 44 that is far apart from the locking plate 41, and a first inclined surface 4411 is provided on the outer edge of the locking insert 441. A locking slot 331 is provided on the outer side surface of the two protective rods 33 on the same side that are far apart from each other. When the protective rod 33 is in the protective state, the two locking rods 44 can rotate to a coaxial state in a direction away from each other. At this time, the control component 43 can slide the two locking plates 41 towards each other, so that the two locking blocks 441 are inserted into the locking slots 331, thereby limiting and locking the protective rod 33 in this state and improving the installation stability of the protective rod 33 during transportation.

[0032] Reference Figure 6 The elastic element 42 is an elastic telescopic rod 421 whose two ends are fixedly connected to the two locking plates 41 close to each other on the side. The elastic telescopic rod 421 has the property of elastic elongation. The elastic telescopic rod 421 is a conventional elastic telescopic structure with an internal spring (not shown in the figure), which will not be described in detail here.

[0033] Reference Figure 6 , Figure 7 and Figure 8 The control component 43 includes four control rods 431 that are rotatably connected at one end to the left and right edges of the two locking plates 41 that are close to each other. The other end of the two control rods 431 on the same side of the two locking plates 41 is connected to a flexible control rope 432 that can be appropriately elastically deformed. The middle part of the support plate 31 is provided with a control hole 311 in the horizontal direction for the control rope 432 to pass through. The rebound force of the control rope 432 is much greater than the rebound force of the elastic telescopic rod 421. Two sets of protruding blocks 35 are fixedly provided on the side of the two guard rods 33 on the same side that are close to each other along their own length direction. An adjusting rod 45 is provided between the two guard rods 33 on the same side along the horizontal direction, and the middle part is fixedly connected to the other end of the control rope 432. Adjusting inserts 46 are fixedly provided at both ends of the adjusting rod 45. A second inclined surface 461 is provided at the outer edge of the adjusting insert 46. An adjusting slot 351 for the adjusting insert 46 to be inserted is opened on the side of the two protruding blocks 35 at the same height that are close to each other. A third inclined surface 3511 is provided at the opening edge of the adjusting slot 351. During the transportation of the distribution box, the protective rod 33 is adjusted to the protective state. Then, after the control rope 432 is elastically stretched, the adjusting blocks 46 at both ends of the adjusting rod 45 are inserted into the adjusting slots 351 on the upper protrusion 35. Since the rebound force of the control rope 432 is much greater than the rebound force of the elastic telescopic rod 421, the two locking plates 41 are driven to slide towards each other. At this time, the locking block 441 is inserted into the corresponding locking slot 331. When it is necessary to unlock, the adjusting block 46 is inserted into the adjusting slot 351 on the lower protrusion 35.

[0034] Reference Figure 7 and Figure 8 The outer periphery of the adjusting plug 46 is provided with an elastic snap-fit ​​47, and the inner wall of the adjusting slot 351 is provided with a positioning groove 352; when the adjusting plug 46 is inserted into the corresponding adjusting slot 351, the elastic snap-fit ​​47 is inserted into the corresponding positioning groove 352, thereby improving the installation stability of the adjusting rod 45. The elastic snap-fit ​​component 47 includes a compression spring 471 and an arc-shaped protrusion 472. The adjusting plug 46 has a placement groove 462 for the compression spring 471 and the arc-shaped protrusion 472 to be inserted. The compression spring 471 presses one side of the arc-shaped protrusion 472, causing a part of the arc-shaped protrusion 472 to protrude from the opening of the placement groove 462. The outer surface of the protruding part of the arc-shaped protrusion 472 is an arc surface, and the arc length corresponding to this arc is a minor arc.

[0035] Reference Figure 9 , Figure 10 and Figure 11 The front and rear lower edges of the box 1 are provided with first slots 12; when the distribution box is installed and in normal use, the protective rod 33 is in a supported state. At this time, the two locking rods 44 are rotated to the coaxial state, and then the control component 43 is used to slide the two locking plates 41 towards each other so that the locking plug 441 can be inserted into the first slot 12, thereby enhancing the installation stability of the locking plate 41 and the box 1. After the distribution box is installed and during subsequent maintenance, the adjusting blocks 46 at both ends of the adjusting rod 45 are inserted into the adjusting slots 351 on the upper protrusion 35. The elastic element 42 causes the two locking plates 41 to slide in opposite directions. At this time, the outer edges of the two locking rods 44 and the locking plates 41 protrude from the bottom surface of the box 1 to form a limiting structure. The two locking rods 44 and the locking plates 41 can be used together to limit the upper part of the maintenance ladder, thereby improving the safety performance during maintenance.

[0036] The implementation principle of this application embodiment is as follows: During the transportation of the distribution box, the protective rod 33 is rotated to a vertically upward protective state along with the connecting rod 32, and the moving wheel 34 faces the ground. The four protective rods 33 protect the vertical edge of the box 1, and the moving wheel 34 assists in short-distance movement. The two locking rods 44 are rotated to a coaxial state in a direction away from each other, and then the adjusting plug 46 is inserted into the adjusting slot 351 of the upper protrusion 35 and positioned by the elastic snap-fit ​​47. This causes the locking plate 41 to slide towards each other, the elastic element 42 is compressed, and the locking plug 441 is inserted into the locking slot 331. The locking rod 44 limits the protective rod 33, ensuring the stability of transportation.

[0037] During the installation of the distribution box, the adjusting plug 46 is inserted into the adjusting slot 351 of the lower protrusion 35 to unlock it. Then, the connecting rod 32 is rotated so that the protective rod 33 is vertically downward. The length of the protective rod 33 is adjusted and fixed so that its lower end abuts against the ground to support the box body 1. The moving wheel 34 is stored between the two support plates 31. After installation, the locking rod 44 is rotated to a coaxial state. By inserting the adjusting plug 46 into the adjusting slot 351 of the lower protrusion 35 in this state, the locking plug 441 is inserted into the first slot 12 of the box body 1, which enhances the installation stability of the locking plate 41 and the box body 1. During maintenance, by inserting the adjusting plug 46 into the adjusting slot 351 of the upper protruding block 35 in this state, the elastic element 42 drives the locking plate 41 to slide in opposite directions, causing the locking plug 441 to disengage from the first slot 12. The outer edge of the locking plate 41 and the two locking rods 44 protrude from the bottom surface of the box 1, thus limiting the upper part of the maintenance ladder.

[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.
