Description

Technical Field

[0001] This invention belongs to the field of low-voltage switchgear technology, specifically relating to a modular integrated low-voltage switchgear. Background Technology

[0002] Modular integrated low-voltage switchgear is a modern electrical device widely used in power distribution systems. It modularizes traditional low-voltage switchgear, making it more flexible, efficient, and reliable. By integrating multiple control, protection, and monitoring functions, modular integrated low-voltage switchgear enables real-time monitoring and management of the power system, improving the system's intelligence level. Furthermore, it can promptly identify and handle faults, enhancing system safety and reliability. In addition, due to its excellent heat dissipation performance and environmental resistance, it can operate stably under various harsh conditions.

[0003] Existing modular integrated low-voltage switchgear requires the bracket to be fixedly connected to the cabinet, and then the drawer unit is slidably installed on the bracket via guide rails. Since the switchgear is often used in industrial production lines, ships, and near fans, these environments are often accompanied by vibration. The vibration is transmitted directly to the contact point between the drawer unit and the terminal block without attenuation through the rigid bracket. The contacts rub continuously in high-frequency micron-level motion, the oxide layer is destroyed and regenerated, leading to a vicious cycle of contact resistance, eventually causing overheating and failure. The tiny deviation between the bracket and the cabinet, amplified by a lever of several hundred millimeters, will cause serious misalignment between the contact of the drawer unit and the terminal block of the wire, resulting in difficulty in plugging and unplugging, one-sided contact, and a sharp increase in contact resistance, eventually causing discharge or burnout. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a modular integrated low-voltage switchgear.

[0005] The technical solution adopted to solve the above technical problems is: a modular integrated low-voltage switch cabinet, including a cabinet with a hollow internal structure, and several heat dissipation slots and wire harness slots arranged linearly and equally spaced through the sides and back of the cabinet. At the same time, a door panel is hinged to the front of the cabinet. An adaptive floating adapter component is set inside the cabinet, and a drawer is installed inside the adaptive floating adapter component. At the same time, several wire holes arranged linearly and equally spaced through the side of the drawer facing the wire harness slot are provided. The adaptive suspension adapter is used to reduce frictional loosening caused by relative movement between the wiring terminals of the components inside the wire hole and the wire terminals passing through the wire harness groove on the back of the cabinet.

[0006] The above technical solutions solve the problems of poor contact and burnout in traditional switchgear under vibration, avoid the risk of discharge and arcing caused by misalignment during insertion and removal, improve the electrical safety level of the overall power distribution system, and significantly extend the service life of electronic components, wire terminals and wires in the drawer, as well as the wires themselves, thereby reducing the later maintenance costs.

[0007] Furthermore, the adaptive suspension adapter includes two sliding seats arranged in a mirror-like orientation, and a frame is fixedly connected between the two sliding seats. At the same time, a number of wire harness holes arranged linearly and equally spaced are opened through the back of the frame, and the wire harness holes and wire harness grooves are located on the same straight line.

[0008] Through the above technical solution, the sliding seat and frame form a basic floating support skeleton inside the cabinet, which ensures that the wire harness hole and the cabinet wire harness groove are strictly coaxially aligned, ensuring that the external wires can pass through the cabinet smoothly and unobstructed and be introduced into the frame, providing a stable physical reference benchmark for the flexible floating of the subsequent mounting plate and drawer.

[0009] Furthermore, the sliding seat is slidably connected to a first limiting rod and a second limiting rod in a cross shape, and the first limiting rod and the second limiting rod are located on different horizontal planes. At the same time, the two ends of the first limiting rod and the second limiting rod are fixedly connected to the inner wall of the cabinet. The outer wall of the sliding seat is rotatably connected to several support plates arranged symmetrically in a circle, and the other end of the support plate is rotatably connected to the inner wall of the cabinet.

[0010] Through the above technical solution, the cross-shaped guide rail structure formed by the first and second limit rods provides a stable and reliable directional sliding constraint for the sliding seat. At the same time, with the rotational support of multiple circumferentially distributed support plates, the lateral impact force transmitted by the cabinet is effectively dispersed, which not only guides the frame to move smoothly along the predetermined trajectory, but also avoids severe swaying and jamming.

[0011] Furthermore, a damping rod is provided between the two support plates, and the telescopic end of the damping rod is rotatably connected to the sliding seat, while the other end of the damping rod is rotatably connected to the inner wall of the cabinet. The damping rod and the support plate rotate in the same direction, and the damping rod and the support plate are used to provide auxiliary support force to improve the balance of the frame inside the cabinet in the horizontal direction.

[0012] By utilizing the above technical solution, the damping rod and the support plate work together, and by taking advantage of the damping energy dissipation characteristics of the damping rod during telescopic motion, the lateral vibration energy can be quickly absorbed and attenuated, which significantly improves the dynamic balance capability of the frame in the horizontal direction, effectively prevents the occurrence of resonance, and ensures the stability of the overall structure.

[0013] Furthermore, several linearly equidistant sliding grooves are provided through both sides of the frame, and an installation plate is provided between four sliding grooves. The installation plate is slidably connected to the frame, and the frame provides sliding guidance for the installation plate. A connecting block is rotatably connected to the outer wall of the installation plate located on one side of the sliding groove.

[0014] Through the above technical solution, the sliding grooves on both sides of the frame provide precise linear sliding guidance for the mounting plate, ensuring the smoothness of the drawer movement. The connecting block that rotates in the longitudinal direction of the outer wall of the mounting plate provides a flexible hinge base for the subsequent connecting block and the mounting plate, ensuring the freedom of movement during the drawer's floating process and avoiding rigid interference.

[0015] Furthermore, the connecting block and the mounting plate are arranged in the longitudinal axis direction of rotation. The connecting block is slidably connected to a sliding rod, and a spring is fixedly connected to one end of the sliding rod. At the same time, the other end of the spring is fixedly connected to the connecting block. A connecting seat is rotatably connected between the ends of the two sliding rods located on one side of the frame that are away from the connecting block. The connecting seat is arranged in an H-shape.

[0016] Through the above technical solution, the No. 1 spring and the No. 2 spring, together with the No. 1 connecting seat of the H-shaped structure, jointly construct a two-way elastic buffer structure. When the drawer unit is displaced due to external vibration, the extension and contraction of the spring can provide active restoring force, effectively buffering the impact in the vertical direction, keeping the contact force between the terminal and the wire constant, and preventing wear caused by hard contact.

[0017] Furthermore, a second slide rod is rotatably connected to the middle of the first connecting seat, and a fixed cylinder is slidably connected to the other end of the second slide rod. A second spring is fixedly connected to the penetrating end of the second slide rod, and the other end of the second spring is connected and fixed to the fixed cylinder. Meanwhile, the fixed cylinder is located in the middle of the frame, and the end of the fixed cylinder away from the second slide rod is welded and fixed to the outer wall of the frame. The drawer and the top surface of the mounting plate are installed and fixed through guide rails.

[0018] Through the above technical solution, the fixed cylinder provides stable axial guidance for the No. 2 slide rod, and together with the No. 2 spring, ensures that the elastic stroke of the mounting plate remains stable during frequent reciprocating motion, avoiding failure due to structural fatigue. At the same time, the guide rail installation method greatly simplifies the installation and maintenance process of the drawer.

[0019] Furthermore, a connecting plate is fixedly connected to the side of the mounting plate facing the wire harness groove of the cabinet, and several mounting seats arranged linearly and equidistantly are installed on the top surface of the connecting plate. The top of the mounting seat is provided with a through hole, and the through hole on the top of the mounting seat is on the same straight line as the wire hole of the drawer. A chain assembly is provided at the center line of the bottom of the connecting plate, and one sprocket in the chain assembly is connected and fixed to the connecting plate. At the same time, another sprocket in the chain assembly is fixedly connected to a first fixing seat, and the other end of the first fixing seat is fixedly installed to the inner wall of the cabinet.

[0020] Through the above technical solution, the through holes of the mounting bracket on the connecting plate provide coaxial guidance for the wire holes on the back of the drawer, ensuring that the wires can pass smoothly without jamming when pulled out. The chain assembly at the bottom is linked with the connecting plate, which effectively maintains the wiring pattern and redundant length of the wire bundle when the connecting plate moves up and down with the drawer, preventing the wires from being damaged or tangled due to pulling.

[0021] Furthermore, adjustment plates are provided on both sides of the first fixed base and the connecting plate, and the adjustment plates are arranged in an L-shape. The connecting shaft at one end of the adjustment plate is rotatably connected to the outer wall of the first fixed base, and the turning end of the adjustment plate is rotatably connected to the outer wall of the connecting plate. A third spring is fixedly connected to the end of the adjustment plate away from the connecting plate, and the other end of the third spring is rotatably connected to the second connecting base.

[0022] Furthermore, the second connecting seat is rotatably connected to a threaded rod on the side away from the third spring, and the other end of the threaded rod is threadedly connected to a knob and a connecting cylinder. At the same time, the knob is rotatably connected to the connecting cylinder. The end of the connecting cylinder away from the threaded rod is rotatably connected to a second fixing seat, and the other end of the second fixing seat is fixedly connected to the inner wall of the cabinet. The rotation direction of the connecting cylinder is set in the longitudinal axis direction.

[0023] Through the above technical solution, by utilizing the threaded transmission structure of the threaded rod and the knob, the operator can easily turn the knob according to the actual working conditions to control the preload of the No. 3 spring, thereby flexibly adjusting the support force of the entire adaptive component for drawers of different weights, which greatly improves the universal adaptability and application range of the modular assembly of the switch cabinet.

[0024] The beneficial effects of this invention are as follows: (1) The present invention uses a horizontally arranged sliding seat, limiting rod, support plate and damping rod, as well as a first spring and a second spring suspended vertically to form a multi-degree-of-freedom suspension structure for the mounting plate and drawer unit inside the cabinet. When the cabinet is subjected to vibration in the industrial environment, the component can simultaneously absorb and buffer the vibration energy in the horizontal and vertical directions, effectively isolate rigid transmission, and avoid relative frictional movement between the electronic components and the wiring terminals in the drawer. This reduces the risk of overheating and burning due to the vicious cycle of contact resistance and improves the reliability of the equipment under harsh working conditions. (2) The present invention guides the wire hole on the back of the drawer coaxially through the mounting seat through hole on the connecting plate. With the linkage structure of the chain assembly at the bottom and the adjustment plate, it ensures that the wire can move smoothly when the drawer is frequently pulled out, without jamming or tangling. At the same time, through the elastic adjustment structure composed of the threaded rod, knob and No. 3 spring, the operator can easily adjust the spring preload by simply rotating the knob, thereby flexibly adapting to the load of drawers of different weights and sizes, and greatly enhancing the compatibility of the low-voltage switch cabinet in various application scenarios. (3) By using connecting components such as connecting blocks and sliding rods, the present invention enables the drawer to be in a suspended state, which can automatically adjust its posture to match the position of the back panel wiring harness groove. This effectively avoids the single-sided contact or insertion / removal difficulties caused by the lever amplification of small deviations in traditional rigid brackets, thereby ensuring reliable electrical connection between the wiring terminals and the terminals of the components inside the drawer and preventing safety hazards such as discharge or burnout caused by poor contact.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-11This embodiment of a modular integrated low-voltage switchgear includes a cabinet 11 with a hollow internal structure. Several linearly spaced heat dissipation slots 12 and wire harness slots 13 are provided through the sides and back of the cabinet 11. A door panel 14 is hinged to the front of the cabinet 11. An adaptive floating adapter component 2 is installed inside the cabinet 11, and a drawer 15 is installed inside the adaptive floating adapter component 2. Several linearly spaced wire holes 16 are provided through the side of the drawer 15 facing the wire harness slots 13. This design solves the problems of poor contact and burnout hazards in traditional switchgear under vibration environments, avoids the risk of discharge and arcing caused by insertion / removal errors, improves the electrical safety level of the overall power distribution system, and significantly extends the service life of electronic components, wire terminals, and wires themselves inside the drawer 15, reducing later maintenance costs. The adaptive floating adapter component 2 is used to reduce the wiring of components inside the wire holes 16. The terminals and the wire terminals passing through the wire harness groove 13 on the back of the cabinet 11 experience relative movement and frictional loosening. The adaptive suspension adapter component 2 includes two sliding seats 227 arranged in mirror-shaped opposite directions. The sliding seats 227 are cross-shaped and slidably connected to a first limiting rod 225 and a second limiting rod 226. The first limiting rod 225 and the second limiting rod 226 are located on different horizontal planes. The cross-shaped guide rail structure formed by the first limiting rod 225 and the second limiting rod 226 provides a stable and reliable directional sliding constraint for the sliding seats 227. At the same time, with the rotational support of multiple circumferentially distributed support plates 223, the lateral impact force transmitted by the cabinet 11 is effectively dispersed. This guides the frame 21 to move smoothly along a predetermined trajectory and avoids severe swaying and jamming. Meanwhile, the two ends of the first limiting rod 225 and the second limiting rod 226 are fixedly connected to the inner wall of the cabinet 11. Several circumferentially symmetrically distributed support plates 223 are rotatably connected to the outer wall of the sliding seats 227.

[0029] like Figures 2-11As shown, a damping rod 224 is provided between the two support plates 223, and the telescopic end of the damping rod 224 is rotatably connected to the sliding seat 227. Simultaneously, the other end of the damping rod 224 is rotatably connected to the inner wall of the cabinet 11. The rotation direction of the damping rod 224 and the support plate 223 is the same. The damping rod 224 and the support plate 223 are used to provide auxiliary support force to improve the horizontal balance of the frame 21 inside the cabinet 11. The other end of the support plate 223 is rotatably connected to the inner wall of the cabinet 11. The frame 21 is fixedly connected between the two sliding seats 227. 227 and frame 21 form a basic floating support skeleton inside cabinet 11, ensuring that the wire harness hole 23 and the wire harness groove 13 of cabinet 11 are strictly coaxially aligned. This ensures that external wires can pass smoothly and unobstructed through cabinet 11 and into frame 21, providing a stable physical reference for the flexible floating of mounting plate 24 and drawer 15. Several linearly and equidistant sliding grooves 22 are provided through both sides of frame 21. The sliding grooves 22 extend vertically, providing longitudinal floating of mounting plate 24 perpendicular to the sliding direction of sliding seat 227. The drawer 15 is guided by a mounting plate 24 between four sliding grooves 22. A connecting plate 213 is fixedly connected to the mounting plate 24 on the side facing the wire harness groove 13 of the cabinet 11. Several mounting seats 212, arranged linearly and equidistantly, are mounted on the top surface of the connecting plate 213. Each mounting seat 212 has a through hole at its top, the diameter of which is larger than the overall diameter of the wire. This allows the wire to pass smoothly through the mounting seat 212 when the drawer 15 is pulled, reducing frictional resistance. Simultaneously, when the drawer 15 is pushed, the wire can pass through the mounting seat. The through hole of 212 automatically returns to its original position to prevent the wire from getting tangled or stuck during the movement of drawer 15. At the same time, the through hole at the top of mounting base 212 and the wire hole 16 of drawer 15 are on the same straight line. A chain assembly 214 is provided at the bottom center line of connecting plate 213, and one sprocket in chain assembly 214 is connected and fixed to connecting plate 213. At the same time, another sprocket in chain assembly 214 is fixedly connected to No. 1 fixing base 220. Adjusting plates 215 are provided on both sides of No. 1 fixing base 220 and connecting plate 213, and the adjusting plates 215 are arranged in an L-shaped structure.

[0030] like Figures 3-11As shown, the connecting shaft at one end of the adjusting plate 215 is rotatably connected to the outer wall of the first fixed seat 220, and the turning end of the adjusting plate 215 is rotatably connected to the outer wall of the connecting plate 213. A third spring 216 is fixedly connected to the end of the adjusting plate 215 away from the connecting plate 213, and a second connecting seat 217 is rotatably connected to the other end of the third spring 216. A threaded rod 218 is rotatably connected to the side of the second connecting seat 217 away from the third spring 216. Utilizing the threaded transmission structure between the threaded rod 218 and the knob 219, the operator can easily rotate the knob 219 according to the actual working conditions to control the preload of the third spring 216, thereby flexibly adjusting the support force of the entire adaptive assembly for drawers 15 of different weights, greatly improving the modular assembly of the switch cabinet. With adaptability and application range, the other end of the threaded rod 218 is threadedly connected to a knob 219 and a connecting cylinder 221. The knob 219 is rotatably connected to the connecting cylinder 221. The end of the connecting cylinder 221 away from the threaded rod 218 is rotatably connected to a second fixing seat 222. The other end of the second fixing seat 222 is fixedly connected to the inner wall of the cabinet 11. The rotation direction of the connecting cylinder 221 is set in the longitudinal axis direction. The other end of the first fixing seat 220 is fixedly installed to the inner wall of the cabinet 11. The mounting plate 24 is slidably connected to the frame 21. The frame 21 provides sliding guidance for the mounting plate 24. The outer wall of the mounting plate 24 located on one side of the slide groove 22 is rotatably connected to a connecting block 25. The rotation direction of the connecting block 25 and the mounting plate 24 is set in the longitudinal axis direction.

[0031] like Figures 4-11 As shown, a sliding rod 26 is slidably connected to the connecting block 25, and a spring 28 is fixedly connected to one end of the sliding rod 26. The other end of the spring 28 is also fixedly connected to the connecting block 25. A connecting seat 27 is rotatably connected between the ends of the two sliding rods 26 located on one side of the frame 21, away from the connecting block 25. A second sliding rod 29 is rotatably connected to the middle of the connecting seat 27, and a fixed cylinder 210 is slidably connected to the other end of the second sliding rod 29. A second spring 211 is fixedly connected to the end of the second sliding rod 29, and the other end of the spring 211 is fixedly connected to the fixed cylinder 210. The fixed cylinder 210 provides stable axial support for the second sliding rod 29. The guide rail, in conjunction with the second spring 211, ensures that the elastic stroke of the mounting plate 24 remains stable during frequent reciprocating motion, avoiding failure due to structural fatigue. At the same time, the guide rail installation method greatly simplifies the installation and maintenance process of the drawer 15. Meanwhile, the fixing cylinder 210 is located in the middle of the frame 21, and the end of the fixing cylinder 210 away from the second slide rod 29 is welded and fixed to the outer wall of the frame 21. The drawer 15 and the top surface of the mounting plate 24 are fixed by the guide rail. The first connecting seat 27 is set in an H-shaped structure. At the same time, several wire harness holes 23 are opened through the back of the frame 21 in a linear and equidistant manner. The wire harness holes 23 and the wire harness groove 13 are located on the same straight line.

[0032] The working principle of this embodiment is as follows: During daily use, the operator can rotate the knob 219 to make the threaded rod 218 move axially relative to the second fixed seat 222, thereby changing the distance between the second connecting seat 217 and its connecting components and the second fixed seat 222, thereby adjusting the tension of the third spring 216, and then through the linkage of the adjusting plate 215 and the connecting plate 213, to adapt to drawers 15 of different weights and sizes, and meet the load requirements under different usage scenarios.

[0033] Then, the wires are passed through the wire harness groove 13 on the back of the cabinet 11, and then introduced into the frame 21 through the wire harness hole 23. Redundant wires are set in the space between the connecting plate 213 and the frame 21. After the wires are passed through the through hole at the top of the mounting base 212, the wire terminals are passed through the wire hole 16 on the back of the drawer 15 to make electrical connections with the electronic components inside the drawer 15. When the drawer 15 is pulled out, the wires are pulled out by the through hole at the top of the mounting base 212.

[0034] When the cabinet 11 is subjected to external force during daily use, the cabinet 11 vibrates. The vibration is transmitted to the frame 21 through the first limit rod 225, the second limit rod 226 and the sliding seat 227. This causes the two first slide rods 26 on both sides of the frame 21 to slide along the connecting block 25 and compress the first spring 28. At the same time, the connecting block 25 and the mounting plate 24 rotate. When the first slide rod 26 moves, it will rotate relative to the first connecting seat 27. This causes the first connecting seat 27 to drive the second slide rod 29 to slide in the fixed cylinder 210 and compress the second spring 211. This causes the drawer 15 and its connecting components mounted on the top of the mounting plate 24 to move slightly in the vertical direction. This ensures that the electronic components and wire terminals in the drawer 15 remain stable and prevents poor contact or damage due to vibration.

[0035] At the same time, when the mounting plate 24 moves up and down within a small range, the connecting plate 213 moves synchronously. The sprocket of the chain assembly 214 at the bottom of the connecting plate 213 meshes with the chain and rotates. Meanwhile, the adjusting plate 215 rotates relative to the connecting plate 213 and the first fixed seat 220. The third spring 216 fixedly connected to the adjusting plate 215 rotates relative to the second connecting seat 217. At the same time, the connecting cylinder 221 rotates relative to the second fixed seat 222, thereby adapting to the movement of the connecting plate 213 and maintaining the flexibility and stability of the overall structure.

[0036] Furthermore, when the frame 21 is subjected to lateral vibration, the sliding seat 227 connected to the top and bottom of the frame 21 slides laterally along the first limiting rod 225 and the second limiting rod 226. The support plate 223 connected to the outer wall of the sliding seat 227 rotates relative to each other, thereby further dispersing and absorbing the energy of the lateral vibration. At the same time, the damping rods 224 on both sides of the sliding seat 227 extend and rotate to different degrees to further suppress the lateral vibration and ensure the smooth operation of the overall structure.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
