Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to an easy-to-install primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] In the construction and operation and maintenance system of smart grid distribution systems, the integrated primary and secondary pole-mounted circuit breaker is the core switching equipment ensuring the safe and stable operation of distribution network lines. This equipment combines the circuit-breaking and closing functions of a primary switch with the intelligent monitoring and control capabilities of a secondary system, enabling rapid identification, isolation, and self-healing of line faults. It is widely used in urban and rural power grid upgrades and distributed power generation grid connection scenarios. Its outdoor installation requires excellent resistance to harsh environments and convenient operation and maintenance adaptability, making it a key fundamental component for achieving distribution automation and improving power supply reliability in smart grids.

[0003] The current mainstream outdoor primary and secondary integrated pole-mounted circuit breaker uses an integrated circuit breaker body as its core carrier. Three poles are integrated on the top surface of the body for electrical connection of power distribution lines. Removable traction handles are provided on both sides of the device for easy lifting and positioning during installation and transportation. Two horizontally arranged support plates are installed on the bottom surface, which are stably fixed to the pole by bolts. The device integrates key components such as operating mechanisms, terminals, current and voltage sensors, and intelligent measurement and control units, meeting core functional requirements such as line on / off control and operational status monitoring. It features a compact structure and high integration.

[0004] When performing on-site maintenance on this type of pole-mounted circuit breaker, the outdoor high-altitude working environment limits the conventional maintenance process. This requires using an insulated boom lift to raise workers to the corresponding installation height before using specialized tools for disassembly, inspection, and replacement. During this process, small parts such as discarded screws and old washers lack temporary storage and are highly susceptible to falling from height. This not only causes debris accumulation on the ground, increasing the workload of subsequent site cleanup, but also poses a risk of falling object impact injuries to personnel and equipment in the work area below, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an easy-to-install primary and secondary integrated pole-mounted circuit breaker, which solves the problem in the above-mentioned related technologies that small parts disassembled during pole-mounted maintenance have no temporary storage carrier, are prone to falling from heights, and cause safety hazards and cleaning difficulties.

[0006] This application provides a primary and secondary integrated pole-mounted circuit breaker that is easy to install, employing the following technical solution: A primary and secondary integrated pole-mounted circuit breaker that is easy to install includes a main body and several poles fixed to the top surface of the main body. Two support rods are arranged side-by-side below the main body. Each support rod has a connecting rod and a positioning rod at both ends. The two ends of the connecting rod are fixedly connected to the same end face of the two support rods, and the two ends of the positioning rod are fixedly connected to the other end face of the two support rods. A first fixing clamp is fixed to the side of the connecting rod away from the support rod. The top surfaces of the two support rods near the positioning rods are fixedly connected to the bottom surface of the main body. Two fixing rods are rotatably connected side-by-side to the sides of the two support rods that are away from each other. The fixed rod can rotate upwards to a vertically upward application state and downwards to a vertically downward storage state. The rotating surface of the fixed rod is parallel to the side of the connecting rod away from the support rod. The support rod is provided with a locking member on the outside to lock and limit the two fixed rods on the same side when they are in the application state. When the two fixed rods are in the application state, the upper end face of each fixed rod is vertically fixed with a receiving rod parallel to the length of the connecting rod in the direction away from the connecting rod. A flexible collection bag with an upward opening is provided between the two receiving rods on the same side. A limiting member is provided on the outside of the receiving rod. The limiting member is used to clamp the opening edge of the flexible collection bag when the fixed rod is in the application state.

[0007] By adopting the above technical solution, the circuit breaker can be quickly positioned and securely installed on the pole using the connecting rod, positioning rod, and first fixing clamp, improving the convenience of outdoor installation. During maintenance, the fixing rod can be rotated to the application state and locked with the locking device. The flexible collection bag can be quickly fixed using the receiving rod and limiting device, providing a dedicated temporary storage carrier for disassembled small parts, effectively avoiding impact injuries to personnel and equipment below caused by falling objects from heights, while reducing the accumulation of debris on the ground and the workload of subsequent cleanup. In the non-maintenance state, the fixing rod can be rotated to the storage state, without occupying extra space, preventing components from being corroded by the harsh outdoor environment, and taking into account installation stability, maintenance safety, and equipment operation and maintenance adaptability.

[0008] Optionally, a middle rod and two diagonal braces are provided below the support rod. The lower ends of the two diagonal braces are rotatably connected to both ends of the middle rod, and the upper ends are rotatably connected to the bottom surface of the two support rods. A second fixing clamp is fixed on the side of the middle rod away from the diagonal braces.

[0009] By adopting the above technical solution, a stable triangular support structure can be formed under the support pole, which further improves the firmness of the connection between the support component and the pole, effectively disperses the weight load of the circuit breaker body, reduces the shaking after the body is installed, and enhances the stability of equipment operation in complex outdoor environments. At the same time, the second fixing clamp and the first fixing clamp form a double fixation, which improves the installation reliability of the equipment on the pole, reduces the safety risks of high-altitude installation and long-term operation, and adapts to the use requirements of harsh outdoor environments.

[0010] Optionally, the limiting member is a limiting rod with one end rotatably connected to the outer circumferential surface of the receiving rod, and a torsion spring is provided at the rotatable connection between the limiting rod and the receiving rod; when the fixed rod is in the application state, the limiting rod is located above the receiving rod, and the limiting rod can rotate to a parallel abutting state with the receiving rod under the action of the torsion spring, and the opening edge of the flexible collection bag can be inserted between the limiting rod and the receiving rod.

[0011] By adopting the above technical solution, the torsion spring drives the limiting rod to automatically rotate to a parallel abutment state with the receiving rod, which can quickly and firmly lock and fix the opening edge of the flexible collection bag without the need for additional manual locking operations, thus improving the installation efficiency of the collection bag during maintenance. The cooperation between the limiting rod and the receiving rod can firmly clamp the bag opening, preventing the collection bag from shifting or falling off due to environmental factors such as outdoor wind, and ensuring the safe storage of small parts. At the same time, the rotatable structure of the limiting rod facilitates quick loading and unloading of the collection bag before and after maintenance, making the operation convenient and meeting the high-efficiency and safe requirements of high-altitude maintenance.

[0012] Optionally, the locking component includes a locking plate that slides horizontally on the top surface of the support rod and a locking rod located between two fixed rods on the same side. The two ends of the locking rod are respectively fixedly connected to the sides of the two fixed rods on the same side that are close to each other. The locking plates on the two support rods can slide towards each other to a protective state of mutual contact and slide away from each other to a locking state that limits the rotation of the fixed rods. When the fixed rods are in the application state, the top surface of the locking rod is flush with the top surface of the support rod. When the locking plate is adjusted to the locking state, the bottom surface of the locking plate is in contact with the top surface of the locking rod.

[0013] By adopting the above technical solution, in the locked state, the bottom surface of the locking plate fits against the top surface of the locking rod in the application state, which can firmly limit the two fixed rods on the same side, preventing accidental rotation of the fixed rods during maintenance and ensuring the stability of the collection bag support structure. In the protective state, the two locking plates abut against each other, which can protect the key structure at the top of the support rod, reducing the intrusion of outdoor dust and debris. The overall structure is simple and easy to operate, without the need for complex locking components, which is suitable for the efficient operation requirements of high-altitude maintenance, while improving the long-term reliability of the equipment.

[0014] Optionally, guide blocks located on both sides of the locking plate are fixed on the top surface of the support rod, and guide notches are provided on the two guide blocks for the edge of the locking plate to slide into. Anti-disengagement protrusions are fixed on the two sides of the locking plate facing the guide blocks.

[0015] By adopting the above technical solution, the guide notch of the guide block can accurately guide the sliding of the locking plate, ensuring smooth and stable state switching; the anti-detachment protrusion can prevent the locking plate from detaching from the guide structure when sliding, improving the installation stability of the locking plate. The overall structure can ensure that the locking plate can reliably achieve the locking and protection functions, meeting the safety requirements of high-altitude operations.

[0016] Optionally, a receiving groove is provided on the top surface of both locking plates, and a sealing plate is rotatably connected to the outer edge of the opening of the two receiving grooves that are close to each other. The sealing plate is parallel to the rotating surface of the fixing rod. When the locking plate is in the protective state, the sealing plate can be rotated to a horizontal state to seal the receiving groove, and when the locking plate is in the locked state, it can be rotated to a vertical state to release the sealing of the receiving groove. A control component for locking the two states of the sealing plate is provided above the locking plate.

[0017] By adopting the above technical solution, the storage trough can be used to fold and store flexible collection bags and temporarily place maintenance tools, improving the convenience of storing tools and accessories during high-altitude maintenance. When the locking plate is in the protective state, the sealing plate horizontally seals the storage trough, effectively preventing outdoor dust and rainwater from entering the trough and avoiding internal components from getting damp or accumulating dust. When the locking plate is switched to the locked state, the sealing plate can be rotated to a vertical state to quickly open the trough, making it easy to retrieve and put in internal items. With the control components locking the sealing plate, the stability of the trough under different working conditions can be ensured, taking into account both storage functionality and protective reliability, and adapting to the long-term operation and maintenance needs of outdoor equipment.

[0018] Optionally, the control component includes two elastic control rods rotatably mounted on both sides of the sealing plate. The elastic control rods have the property of active elastic extension, and the rotation surface of the elastic control rods is parallel to the rotation surface of the sealing plate. A first slot is provided on the side of the guide block facing the sealing plate, and a second slot is provided on the top surface of the support rod. When the locking plate is in the locked state and the sealing plate is in the horizontal state, the elastic control rods can rotate to the horizontal state in the direction towards the guide block, and the end of the elastic control rod is elastically engaged in the first slot. When the locking plate is in the locked state and the sealing plate is in the vertical state, the elastic control rods can rotate to the vertically downward vertical state, and the end of the elastic control rod is elastically engaged in the second slot.

[0019] By adopting the above technical solution, and utilizing the interlocking action of the elastic control rod with different slots, stable locking of the sealing plate in both horizontal and vertical open states can be quickly achieved without the need for additional locking components. This simple operation is well-suited to the high-efficiency requirements of high-altitude maintenance. The elastic control rod has its own active elastic extension capability, ensuring a secure connection after being inserted into the slot. This effectively prevents accidental displacement of the sealing plate due to outdoor wind, equipment vibration, and other factors, ensuring the sealing of the collection tank in its protected state and preventing dust and rainwater from damaging the internal collection bags or tools. Furthermore, switching states is simply a matter of rotating the elastic control rod to disengage it from the corresponding slot; the process is simple and easy to operate. This structure, in conjunction with the locking plate and the sealing plate, ensures the reliability of the sealing plate's state under different working conditions, simplifies the overall operation process, and improves the equipment's operational adaptability and outdoor stability.

[0020] Optionally, the two support rods have horizontally oriented adjustment holes on their opposite sides. When the fixed rod is in its retracted state, it has an adjustment slot on its side facing the support rod that coincides with the adjustment holes. The support rod has a connecting cavity inside and a fixed through hole on its top surface that communicates with the connecting cavity. A first adjustment rod slides inside the adjustment hole, and an elastic pressing member is provided to drive the first adjustment rod to slide along the direction close to the connecting cavity. A second adjustment rod slides inside the fixed through hole. A third adjustment rod is provided inside the connecting cavity, with its two ends rotatably connected to the inner end of the first adjustment rod and the lower end of the second adjustment rod, respectively. An adjustment plate is fixed on the outer periphery of the elastic control rod. When the fixed rod is in its retracted state and the elastic control rod is inserted into the first slot, the adjustment plate abuts against the top surface of the second adjustment rod, and the outer end of the first adjustment rod is inserted into the adjustment slot at this time.

[0021] By adopting the above technical solution and utilizing the linkage design of the adjusting plate, the second adjusting rod, the third adjusting rod, and the first adjusting rod, automatic locking of the fixed rod in its retracted state can be achieved: when the sealing plate horizontally blocks the retractable slot, the adjusting plate presses against the second adjusting rod, which in turn drives the first adjusting rod to insert into the adjusting slot via the third adjusting rod, thus completing the fixed rod's retracted limit and preventing accidental rotation; to unlock, simply rotate the elastic control rod to disengage it from the slot, the adjusting plate releases its pressure on the second adjusting rod, and the elastic pressing component drives the first adjusting rod to reset and disengage from the slot. This linkage structure requires no additional manual operation, improving the convenience and reliability of the retractable locking mechanism and adapting to the operational needs of high-altitude operations.

[0022] Optionally, the elastic compression member includes a protruding plate fixed on the outer periphery of the first adjusting rod and a first spring located on the side of the protruding plate away from the connecting cavity. The adjusting insertion hole has an adjusting groove at the opening edge facing the connecting cavity for inserting the first spring and the protruding plate. The two ends of the first spring are fixedly connected to one side of the protruding plate and the bottom wall of the adjusting groove, respectively.

[0023] By adopting the above technical solution, the first spring can drive the first adjusting rod to automatically reset through elastic force, ensuring that when the fixed rod is unlocked from the locked state, the first adjusting rod can quickly disengage from the adjusting slot; the adjusting groove provides a stable installation space for the protruding plate and the first spring, avoiding the impact of component shaking on the transmission effect. The structure is simple and reliable, and is suitable for the convenient operation requirements of high-altitude operations.

[0024] Optionally, a guide slope is provided at the outer edge of the end of the first adjusting rod away from the third adjusting rod.

[0025] By adopting the above technical solution, the guide slope can guide the first adjusting rod to smoothly insert into the adjusting slot during the transmission process, avoiding jamming, improving the smoothness of the locking operation, and ensuring the reliability of the locking state of the fixed rod.

[0026] In summary, this application includes the following beneficial technical effects: In this application, the connecting rod, positioning rod, and first fixing clamp can be used to achieve rapid positioning and stable installation of the circuit breaker on the pole, improving the convenience of outdoor installation. During maintenance, the fixing rod can be turned to the application state and locked by the locking device. The receiving rod and limiting device can be used to quickly fix the flexible collection bag, providing a dedicated temporary storage carrier for disassembled small parts, effectively avoiding impact injuries to personnel and equipment below caused by falling objects from heights, while reducing the accumulation of debris on the ground and the workload of subsequent cleanup. In the non-maintenance state, the fixing rod can be turned to the storage state without occupying extra space. Attached Figure Description

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

[0030] Example: Reference Figure 1 , Figure 2 and Figure 3 A primary and secondary integrated pole-mounted circuit breaker that is easy to install includes a body 1 and three pole posts 11 fixed on the top surface of the body 1. A support assembly 2 is provided below the body 1. The support assembly 2 includes two support rods 21 arranged side by side below the body 1. Each support rod 21 has a connecting rod 22 and a positioning rod 23 at its two ends. The two ends of the connecting rod 22 are fixedly connected to the same end face of the two support rods 21, and the two ends of the positioning rod 23 are fixedly connected to the other end face of the two support rods 21. A first fixing clamp 24 is fixedly provided on the side of the connecting rod 22 away from the support rod 21. When installing the pole-mounted circuit breaker, the support assembly 2 is first fixed to the utility pole by the first fixing clamp 24 and the second fixing clamp 27. Then, the body 1 is placed on the top surface of the two support rods 21 using hoisting equipment. Finally, the bottom surface of the body 1 is fixed to the top surface of the two support rods 21 near the positioning rod 23 using bolts.

[0031] Reference Figure 2 and Figure 3 Below the support rod 21, there is a middle rod 25 and two diagonal braces 26. The lower ends of the two diagonal braces 26 are rotatably connected to the two ends of the middle rod 25, and the upper ends are rotatably connected to the bottom surface of the two support rods 21. A second fixing clamp 27 is fixed on the side of the middle rod 25 away from the diagonal braces 26. The diagonal braces 26 and the second fixing clamp 27 are used to enhance the support stability of the two support rods 21 on the body 1.

[0032] Reference Figure 4 and Figure 5 The support rod 21 is provided with a fixing component 3 on its exterior. The fixing component 3 includes two fixing rods 31 that are rotatably connected side by side to the two support rods 21 on their opposite sides. The rotation surface of the fixing rods 31 is parallel to the side of the connecting rod 22 that is away from the support rods 21. The fixing rods 31 can rotate upward to a vertically upward application state and downward to a vertically downward storage state. The support rod 21 is provided with a locking member 4 on its exterior to lock and limit the two fixing rods 31 on the same side when they are in the application state. When both fixed rods 31 are in the application state, a receiving rod 32 parallel to the length of the connecting rod 22 is vertically fixed on the upper end face of each rod 31 in a direction away from the connecting rod 22; a flexible collection bag 34 with its opening facing upward is provided between the two receiving rods 32 on the same side; a limiting member 33 is provided on the outside of the receiving rod 32; the limiting member 33 is a limiting rod 331 with one end rotatably connected to the outer peripheral surface of the receiving rod 32; a torsion spring (not shown in the figure) is provided at the rotatable connection between the limiting rod 331 and the receiving rod 32; when the fixed rod 31 is in the application state, the limiting rod 331 is located above the receiving rod 32; When overhauling the pole-mounted circuit breaker, first adjust the fixing rod 31 to the application state, then place the flexible collection bag 34 between the two receiving rods 32 on the same side. At this time, the limiting rod 331 can rotate to the abutting state parallel to the receiving rod 32 under the action of the torsion spring. The opening edge of the flexible collection bag 34 can be inserted between the limiting rod 331 and the receiving rod 32, so that the debris generated during the maintenance can be temporarily placed in the flexible collection bag 34. After the maintenance is completed, remove the flexible collection bag 34, and then adjust the fixing rod 31 to the vertical downward storage state.

[0033] Reference Figure 5 and Figure 6 The locking component 4 includes a locking plate 42 that slides horizontally on the top surface of the support rod 21 and a locking rod 41 located between two fixed rods 31 on the same side, wherein the two ends of the locking rod 41 are fixedly connected to the sides of the two fixed rods 31 on the same side that are close to each other. The top surface of the support rod 21 is fixed with guide blocks 28 located on both sides of the locking plate 42. The two guide blocks 28 are provided with guide notches for the edge of the locking plate 42 to slide into. The two sides of the locking plate 42 facing the guide blocks 28 are fixed with anti-detachment protrusions 421. The locking plates 42 on the two support rods 21 can slide towards each other to a protective state of mutual contact, and slide away from each other to a locking state that limits the rotation of the fixed rod 31. When the fixed rod 31 is in the application state, the top surface of the locking rod 41 is flush with the top surface of the support rod 21. After the locking plate 42 is adjusted to the locked state, the bottom surface of the locking plate 42 is in contact with the top surface of the locking rod 41, thus completing the locking of the two fixed rods 31 on the same side in this state.

[0034] Reference Figure 6 , Figure 7 and Figure 8 The top surfaces of the two locking plates 42 are provided with storage grooves 422 for the flexible collection bag 34 to be folded and inserted. The outer edges of the openings of the two storage grooves 422 that are close to each other are rotatably connected with sealing plates 43, wherein the sealing plates 43 are parallel to the rotating surface of the fixing rod 31, and a control component 5 is provided above the locking plates 42. When the locking plate 42 is in the protective state, the sealing plate 43 can be rotated to a horizontal state that seals the collection trough 422; when the locking plate 42 is in the locked state, the sealing plate 43 can be rotated to a vertical state that releases the seal on the collection trough 422, making it easier to remove the flexible collection bag 34, and at this time, maintenance tools can be temporarily placed into the collection trough 422; the staff can use the control piece 5 to lock and limit the two states of the sealing plate 43.

[0035] Reference Figure 6 and Figure 8 The control component 5 includes two elastic control rods 51 rotatably mounted on both sides of the sealing plate 43. The elastic control rods 51 have the property of active elastic extension. The rotation surface of the elastic control rods 51 is parallel to the rotation surface of the sealing plate 43. The elastic control rods 51 are conventional telescopic structures with internal springs (not shown in the figure), which will not be described in detail here. The guide block 28 has a first slot 281 on the side facing the sealing plate 43, and the support rod 21 has a second slot 211 on the top surface. When the locking plate 42 is locked and the sealing plate 43 is horizontal, the elastic control lever 51 can rotate to a horizontal position in the direction toward the guide block 28, and the end of the elastic control lever 51 is elastically engaged in the first slot 281; when the locking plate 42 is locked and the sealing plate 43 is vertical, the elastic control lever 51 can rotate to a vertically downward position, and the end of the elastic control lever 51 is elastically engaged in the second slot 211.

[0036] Reference Figure 9 , Figure 10 and Figure 11 The two support rods 21 have horizontal adjustment holes 212 on their sides that are far apart from each other. When the fixed rod 31 is in the retracted state, it has an adjustment slot 311 on its side facing the support rod 21 that can coincide with the adjustment holes 212. The support rod 21 has a connecting cavity 213 inside and a fixed through hole 214 communicating with the connecting cavity 213 on its top surface in the vertical direction. The support rod 21 is provided with an adjusting member 6, which includes a first adjusting rod 61 slidably disposed in the adjusting socket 212 and an elastic pressing member 64 disposed in the adjusting socket 212. The elastic pressing member 64 can drive the first adjusting rod 61 to slide along the direction close to the connecting cavity 213. A second adjusting rod 62 is slidably disposed in the fixed through hole 214. A third adjusting rod 63 is provided in the connecting cavity 213, with its two ends respectively rotatably connected to the inner end of the first adjusting rod 61 and the lower end of the second adjusting rod 62. A guide slope 611 is provided at the outer edge of the end of the first adjusting rod 61 away from the third adjusting rod 63. An adjusting plate 52 is fixedly disposed on the outer periphery of the elastic control rod 51. When the fixed rod 31 is in the retracted state and the elastic control rod 51 is engaged in the first slot 281, the adjusting plate 52 presses against the top surface of the second adjusting rod 62, and the third adjusting rod 63 drives the first adjusting rod 61 to slide outward, so that the outer end of the first adjusting rod 61 is inserted into the adjusting slot 311, thereby locking the fixed rod 31 in this state; when the sealing plate 43 is rotated upward to open, the adjusting plate 52 stops pressing the second adjusting rod 62, and the first adjusting rod 61 is reset under the action of the elastic pressing member 64 and disengages from the adjusting slot 311.

[0037] Reference Figure 10 The elastic compression member 64 includes a protruding plate 641 fixed on the outer periphery of the first adjusting rod 61 and a first spring 642 located on the side of the protruding plate 641 away from the connecting cavity 213. The adjusting insertion hole 212 is provided with an adjusting groove 2121 at the opening edge facing the connecting cavity 213 for inserting the first spring 642 and the protruding plate 641. The two ends of the first spring 642 are fixedly connected to one side of the protruding plate 641 and the bottom wall of the adjusting groove 2121, respectively.

[0038] The implementation principle of this application embodiment is as follows: Installation status: The support assembly 2 is fixed to the utility pole by the first fixing clamp 24 and the second fixing clamp 27. The circuit breaker body 1 is placed on the top surface of the two support rods 21 using hoisting equipment. The bottom surface of the body 1 is fastened to the top surface of the support rod 21 near the positioning rod 23 by bolts. The diagonal brace 26 works with the intermediate rod 25 to improve the stability of the support.

[0039] Maintenance status: First, rotate the fixing rod 31 to the vertically upward application state, then rotate the sealing plate 43 to the vertically upward state, and then slide the locking plate 42 to the locked state. The elastic control rod 51 is inserted into the second slot 211 to lock the sealing plate 43 and the locking plate 42. At this time, the bottom surface of the locking plate 42 is in contact with the top surface of the locking rod 41, thus limiting the two fixing rods 31 on the same side. Finally, take out the flexible collection bag 34 from the storage trough 422 and place the flexible collection bag 34 between the two receiving rods 32. The limiting rod 331 is pressed against the bag opening under the action of the torsion spring. The storage trough 422 can also be used to temporarily place maintenance tools.

[0040] Storage state (i.e., when the pole-mounted circuit breaker is in normal use): After maintenance, remove the collection bag, fold it, and place it into the storage trough 422. Then, slide the locking plate 42 to the protective state and turn the sealing plate 43 down to seal the storage trough 422. Simultaneously, turn the fixing rod 31 to the vertical downward state. At this time, the adjusting plate 52 presses the top surface of the second adjusting rod 62, and the first adjusting rod 61 is inserted into the adjusting slot 311 through the transmission of the third adjusting rod 63, thus completing the storage and locking of the fixing rod 31 in this state. The first spring 642 of the elastic pressing member 64 can drive the first adjusting rod 61 to reset, which is convenient for the next operation.
