Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically an assembled power distribution cabinet. Background Technology
[0002] As the core terminal equipment of a power distribution system, modular switchgear is mainly used in various power consumption scenarios such as industrial production, construction projects, municipal facilities, and data centers, undertaking the key functions of power distribution, control, and safety assurance. Its core function is to receive high-voltage or low-voltage power from the upstream power supply system and, through internally modularly designed switching elements, circuit breakers, relays, fuses, and other components, distribute the power as needed to various electrical equipment (such as machine tools, lighting, air conditioning, automated production lines, etc.), achieving precise power distribution to different areas and loads. However, when installing various components in existing distribution cabinets, the components can only be assembled through the front of the cabinet. That is, the operator must complete the fixing, wiring and debugging of the components within the pre-set installation space on the front of the cabinet. Due to the dense layout of components inside the distribution cabinet and the limitation of the front operating space by the cabinet structure, when installing multi-circuit components or adjusting subsequent wiring, the operator must complete the precise alignment and line connection in a narrow space. This results in frequent adjustments to the operating posture during the installation process, which not only increases the difficulty of the operation, but may also affect the installation accuracy due to insufficient operating space, thereby affecting the assembly efficiency of the power distribution system.
[0003] Therefore, this utility model provides an assembled power distribution cabinet to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an assembled power distribution cabinet, which solves the problem mentioned above that components can only be assembled through the front of the power distribution cabinet, meaning that operators need to complete the component fixing, wiring, and debugging processes within the pre-set installation space on the front of the cabinet.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembled power distribution cabinet, comprising: The distribution cabinet contains multiple sets of L-shaped slot steel rods for fixing components, a rectifier cabinet, a heat sink, and an air switch. Assembly mechanism: Multiple assembly mechanisms are movably connected to the inside of the distribution cabinet and slide along the inner wall of the distribution cabinet; The assembly mechanism includes a heat sink plate detachably connected to an L-shaped slot steel rod. Limiting groove plates are fixedly connected to both sides of the heat sink plate. A protective plate is movably connected between the two limiting groove plates, and a rotating plate is rotatably connected inside the protective plate. The rotating plate has threaded grooves for disassembling and installing an air switch. The rotating plate and the protective plate are rotatably connected via a shaft. A ratchet is movably connected inside the shaft, and a locking pin matching the ratchet is rotatably connected to the side of the protective plate via a torsion spring. The other end of the ratchet is fixedly connected to the side of the rotating plate, allowing the protective plate to be pulled out from inside the distribution cabinet when installing an air switch or other components. The rotating plate can be rotated according to a suitable installation angle, and the ratchet and locking pin can achieve fixation during installation. After installation, rotating the shaft causes the locking pin to rotate in the opposite direction, disengaging the locking pin from the rotating plate. After adjusting the component angle, the locking pin and the rotating plate are locked together by the torsion spring. Both the ratchet and the locking pin are located inside the rotating shaft.
[0006] Preferably, the inner sides of the two limiting groove plates are provided with sliding grooves to facilitate the sliding of the guard plate, and the side surfaces of the guard plate are movably connected with rollers that match the sliding grooves.
[0007] Preferably, the inner side of the protective plate is provided with a cable insertion slot for the cable, and a clip is fixedly connected to the bottom of the protective plate near the cable insertion slot. A slot matching the clip is fixedly connected to the heat sink plate. When the protective plate slides into the bottom of the heat sink plate, the clip is inserted into the interior of the top plate and exposed on the outside of the top plate. At this time, the wire harness is passed through the clip, causing the two ends of the clip to expand outward, thereby making the clip and the top plate mutually engage and fix each other.
[0008] Preferably, the inner side of the power distribution cabinet near the end of the heat sink is provided with two adjustment mechanisms for organizing the wire harness. The adjustment mechanism includes two fixed plates, one of which is movably connected to a cover plate via a hinge, and the other fixed plate is fixedly connected to a tenon that interlocks with one side of the cover plate. The two fixed plates are internally fixedly connected to three limiting rods, and the side of the heat sink near the fixed plate is fixedly connected to a limiting block that matches the limiting rods.
[0009] Preferably, the inner side of the cover plate is provided with three wire clips that match the wire harness, and the three wire clips correspond to the neutral wire, the live wire and the ground wire respectively, and a handle is fixedly connected to the other side of the cover plate.
[0010] Preferably, both ends of the protective plate are fixedly connected with handles for easy pulling out, and the three grooves of the limiting block and the limiting rod are fixedly connected with anti-slip damping pads, so that the distance between the two heat sinks can be flexibly adjusted according to the size of the component by removing the screws on the heat sink and the L-shaped slot steel rod.
[0011] This utility model provides an assembled power distribution cabinet. Compared with the prior art, it has the following advantages: (1) This modular power distribution cabinet achieves flexible adaptation of component assembly space and angle through the detachable connection between the heat dissipation plate and the L-shaped slot steel rod, the sliding cooperation between the limiting slot plate and the side roller of the guard plate, and the locking pin connecting the rotating plate and the guard plate with the rotating shaft, ratchet and torsion spring. The operator can pull the guard plate out from the inside of the power distribution cabinet with the help of the handle, breaking the traditional limitation of operation in the narrow front space. At the same time, the angle of the rotating plate can be adjusted according to the installation requirements of components such as air switches, and the angle is fixed by the engagement of the ratchet and the locking pin. Precise installation can be completed without frequent adjustment of the operating posture. The distance between the heat dissipation plates can also be adjusted by the sliding of the limiting block on the limiting rod to avoid spatial interference after the components are installed, which significantly improves the convenience and accuracy of assembly.
[0012] (2) This modular distribution cabinet achieves orderly organization and classification of wire harnesses through the wire insertion slots on the inner side of the protective plate, the clips matching the slots of the heat sink at the bottom of the protective plate, and the adjustment mechanism (including the fixing plate, the cover plate connected by the hinge, and the wire clips corresponding to the neutral, live, and ground wires) on the inner side of the distribution cabinet. When wiring, the wire harness is first sorted out through the wire insertion slots. When the protective plate is pushed back, the clips are inserted into the slots and engaged with the wire harness to complete the initial fixation. Then, the cover plate is opened by the handle, and different wire harnesses are embedded into their respective dedicated wire clips. The cover plate is closed and engaged with the fixing plate to prevent messy tangling and confusion of the lines. This reduces wiring interference and provides a clear basis for line identification for subsequent maintenance and debugging, ensuring the standardization of power distribution system line management.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please see Figures 1 to 6 An assembled power distribution cabinet, comprising: The distribution cabinet 1 is equipped with multiple sets of L-shaped slot steel rods for fixing components, rectifier cabinet 2, heat sink 3 and air switch 6; Assembly mechanism 4, multiple sets of assembly mechanism 4 are movably connected to the inside of the power distribution cabinet 1 and slide along the inner wall of the power distribution cabinet 1; The assembly mechanism 4 includes a heat sink 41 that is disassembled and connected to an L-shaped slot steel rod. Limiting groove plates 42 are fixedly connected to both sides of the heat sink 41. A protective plate 44 is movably connected between the two limiting groove plates 42. A rotating plate 45 is rotatably connected inside the protective plate 44. The rotating plate 45 has threaded grooves for disassembling and installing the air switch. The rotating plate 45 and the protective plate 44 are rotatably connected via a rotating shaft 46. A ratchet 47 is movably connected inside the rotating shaft 46. A locking pin 48 matching the ratchet 47 is rotatably connected to the side of the protective plate 44 via a torsion spring. The other end of the ratchet 47 is fixedly connected to the side of the rotating plate 45, so that the air switch 6 can be installed... When installing other components, the guard plate 44 can be pulled out from the inside of the distribution cabinet 1, and the rotating plate 45 can be rotated according to the appropriate installation angle. Under the action of the ratchet 47 and the locking pin 48, the installation can be fixed. After the installation is completed, the rotating shaft 46 is rotated to drive the locking pin 48 to rotate in the opposite direction, so that the locking pin 48 is disengaged from the rotating plate 45. After adjusting the component angle, the locking pin 48 and the rotating plate 45 are engaged with each other under the action of the torsion spring for fixation. The inner side of the two limiting slot plates 42 is provided with a sliding groove to facilitate the sliding of the guard plate 44, and the side of the guard plate 44 is movably connected with a roller 43 that matches the sliding groove. The ratchet 47 and the locking pin 48 are both located inside the rotating shaft 46. During operation, the operator first applies pulling force through the handles 414 at both ends of the guard plate 44. The rollers 43 on the side of the guard plate 44 roll along the sliding grooves on the inner side of the limiting groove plate 42, pulling the guard plate 44 to a suitable position for component installation. This eliminates the limitation of operating in the narrow space in front of the cabinet, providing a spacious working area for component installation. Subsequently, according to the installation requirements of the air switch 6 or other components to be installed, the rotating plate 45 is rotated. The rotating plate 45 drives the ratchet 47 to rotate synchronously through the rotating shaft 46. The locking pins 48 on the side of the guard plate 44 remain in contact with the ratchet 47 under the elastic force of the torsion spring. When the rotating plate 45 is rotated to the appropriate installation angle, the locking pins 48 engage with the tooth grooves of the ratchet 47, fixing the angle of the rotating plate 45. The operator can operate in a state without angular deviation. After completing the precise operations such as bolt fixing and wiring connection of the components, and after the initial installation and wiring of the components are completed, rotate the shaft 46. The shaft 46 drives the locking pin 48 to rotate in the opposite direction and disengage from the tooth groove of the ratchet 47. At this time, the angle of the rotating plate 45 can be finely adjusted to the optimal working position of the component. After releasing the shaft 46, the locking pin 48 engages with the ratchet 47 again under the action of the torsion spring return force, completing the final fixing of the rotating plate 45. Finally, push the handle 414 to push the protective plate 44 back into the distribution cabinet 1 along the slide, completing a single component assembly. The ends of the two limit slot plates 42 are provided with slots to facilitate the removal of the protective plate 44. The slots match the rollers 43, so that when it is necessary to replace or repair the protective plate 44 inside the distribution cabinet 1, the protective plate 44 can be removed from the heat sink 41. Example
[0017] Please see Figures 1 to 6This embodiment provides a technical solution based on embodiment one: The inner side of the protective plate 44 is further provided with a cable insertion slot 49 for wiring, and a clip 410 is fixedly connected to the bottom of the protective plate 44 near the cable insertion slot 49. A slot 412 matching the clip 410 is fixedly connected to the heat sink 41. When the protective plate 44 slides into the bottom of the heat sink 41, the clip 410 is inserted into the interior of the top plate 411, and the clip 410 is exposed on the outside of the top plate 411. At this time, the wire harness is passed through the clip 410, causing both ends of the clip 410 to expand outwards, thereby causing the clip 410 and the top plate 411 to interlock and be fixed. Two adjustment mechanisms 5 for organizing the wire harness are provided on the inner side of the distribution cabinet 1 near the end of the heat sink 41. The adjustment mechanism 5 includes two fixing plates 51, and one of the fixing plates 51 has a through-hole... A cover plate 52 is movably connected via a hinge 55, and a side tenon that interlocks with one side of the cover plate 52 is fixedly connected to another fixed plate 51. Three limiting rods 53 are fixedly connected inside the two fixed plates 51, and a limiting block 413 matching the limiting rod 53 is fixedly connected to the side of the heat sink 41 near the fixed plate 51. Three wire clips 56 matching the wiring harness are provided on the inner side of the cover plate 52, and the three wire clips 56 correspond to the neutral wire, live wire and ground wire respectively. A handle 54 is fixedly connected to the other side of the cover plate 52. Both ends of the guard plate 44 are fixedly connected to handles 414 for easy pulling out. Anti-slip damping pads are fixedly connected to the inner side of the three grooves of the limiting block 413 that match the limiting rod 53, so that the distance between the two heat sinks 41 can be flexibly adjusted according to the size of the component by removing the screws on the heat sink 41 and the L-shaped slot steel rod. During operation, first, according to the size and specifications of the component to be installed, remove the fixing screws connecting the heat sink 41 to the L-shaped slot steel rod. The distance between the two heat sinks 41 is flexibly adjusted by sliding the limiting block 413 on one side of the heat sink 41 onto the limiting rod 53 of the adjusting mechanism 5, ensuring no space interference after component installation. After adjustment, tighten the screws again. The anti-slip damping pad in the groove of the limiting block 413 increases the friction with the limiting rod 53, preventing the heat sink 41 from loosening or shifting during use. During component wiring, the wire harness is neatly arranged through the insertion slot 49 inside the protective plate 44 to prevent tangled wiring. When the protective plate 44 is pushed back to the bottom of the heat sink 41, the clips 410 on the protective plate 44 are simultaneously inserted into the heat sink 41. Inside slot 412, the combed wire harness is passed through clip 410. The two ends of clip 410 expand outward under the pressure of the wire harness, forming a tight engagement with the inner wall of slot 412, thus achieving initial fixation and positioning of the wire harness. Then, by pulling handle 54, the cover plate 52 of adjustment mechanism 5 is pulled, causing the cover plate 52 to rotate around hinge 55 and disengage from the tenon structure of the other side fixing plate 51. The initially combed neutral wire, live wire, and ground wire are respectively embedded into the three wire clips 56 on the inner side of the cover plate 52. The elastic structure of the wire clips 56 can firmly hold the wire harness. Then, the cover plate 52 is closed, so that one side of it is engaged and fixed with the tenon of fixing plate 51, completing the classification and organization of the wire harness. This not only avoids confusion between different lines but also provides a clear basis for line identification for subsequent maintenance and debugging.
[0018] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0019] Working principle: First, according to the size of the component to be installed, remove the fixing screws of the heat sink 41 and the L-shaped slot steel rod. Adjust the distance between the two heat sinks 41 by sliding the limit block 413 on the limit rod 53. After tightening the screws, pull the guard plate 44 with the handle 414. The roller 43 rolls along the groove of the limit slot plate 42 to pull out the guard plate 44. Rotate the rotating plate 45 to drive the ratchet 47 to rotate through the rotating shaft 46. The locking pin 48 engages with the ratchet 47 under the action of the torsion spring to fix the angle of the rotating plate 45. After the air switch 6 and other components are installed, fine adjust the angle of the rotating plate 45 and lock it in place again. Then, pass the wire harness through the wire insertion slot 49. When the guard plate 44 is pushed back, the clip 410 inserts into the slot 412 and locks it in place with the wire harness. Then, open the cover plate 52 of the adjustment mechanism 5 with the handle 54 and insert the neutral wire, live wire, and ground wire into the corresponding wire clips 56 respectively. Close the cover plate 52 and lock it with the fixing plate 51. Finally, push the guard plate 44 completely back into the distribution cabinet 1.
