Description

Technical Field

[0001] This utility model relates to the field of power equipment support device technology, and in particular to a multi-voltage adaptable adjustable DC busbar support frame. Background Technology

[0002] Adjustable DC busbar support frames are mechanical structures used to fix DC busbars. They adapt to the installation requirements of different busbar specifications through telescopic and rotational adjustment functions. They are characterized by stable structure and flexible installation and are commonly used in busbar connection systems of power equipment. Multi-voltage adaptable equipment is closely related to the support frame because it needs to be compatible with the layout of busbars of different voltage levels. The support frame adjusts its size and angle according to the spacing and direction requirements of different voltage busbars in the equipment. The busbar position is fixed by locking nodes to ensure that the insulation distance between high and low voltage busbars meets the standards, while also adapting to the displacement changes of busbar thermal expansion and contraction.

[0003] In existing technologies, some adjustable DC busbar support frames achieve stable support and flexible adjustment of the DC busbar through a modular structural design. The core components include a fixed base, an adjusting screw, a sliding bracket, and insulating pads. During operation, the fixed base is rigidly connected to the cabinet or mounting surface via bolts, providing a stable foundation for the overall structure. The adjusting screw runs between the fixed base and the sliding bracket; rotating the screw clockwise or counterclockwise drives the sliding bracket to move precisely in the horizontal or vertical direction.

[0004] However, in actual use, the support frame, which is difficult to store and fix as a whole, can only be stacked in a scattered manner. This stacking method will lead to a significant decrease in the utilization rate of storage space. The originally orderly storage area becomes messy and disorganized. Moreover, the scattered parts are not easy to classify, manage and count. When staff need to find a support frame of a specific specification, they need to spend more time, which increases the workload of storage management. In order to address the above problems, a multi-voltage adaptable adjustable DC busbar support frame is proposed. Utility Model Content

[0033] 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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-voltage adaptable adjustable DC busbar support frame, including a left mounting frame 1. The left mounting frame 1 is fixed to the mounting surface of the electrical cabinet or equipment by bolts, providing left-side support for the busbar mounting base 5, and also serving as the sliding base for the right mounting frame 3. It is the left-side load-bearing component of the entire support frame. A storage mounting mechanism 2 is provided on the rear side of the left mounting frame 1. The right mounting frame 3 is slidably connected to the outside of the storage mounting mechanism 2. The right mounting frame 3 and the left mounting frame 1 together constitute the support frame of the busbar. By sliding and adjusting the distance between the two, the width of the support frame can be flexibly adjusted, providing stable support for busbars of different specifications. A position adjustment mechanism 4 is fixedly connected to the right side of the right mounting frame 3.

[0035] The position adjustment mechanism 4 includes a connecting rod 41 with a smooth surface. The outer part of the connecting rod 41 is slidably engaged with the preset guide hole of the right mounting bracket 3, allowing it to slide freely along the axial direction. The outer part of the connecting rod 41 is slidably connected to the inside of the right mounting bracket 3. A mounting spring 42 is sleeved on the outer part of the connecting rod 41. The mounting spring 42 is in an extended state in its natural state, applying a continuous pushing force to the connecting rod 41 so that its locking head is always inserted into the through hole 46, ensuring reliable locking. When the position needs to be adjusted, the connecting rod 41 can be pulled to release the lock by overcoming the spring force. The operation is convenient. A pull plate 43 is fixedly connected to the outer part of the connecting rod 41. The pull plate 43 provides a convenient force application point for the operator, making the operation of pulling the connecting rod 41 more effortless. This allows the connecting rod 41 to separate from the sliding mounting block 45, and then allows the sliding mounting block 45 to slide inside the inner limiting groove 44 of the right mounting bracket 3.

[0036] A limiting groove 44 is provided on the outer front side of the right mounting bracket 3. The limiting groove 44 provides a guide track for the sliding mounting block 45, ensuring that the sliding mounting block 45 moves smoothly in a straight line while limiting its lateral displacement. Multiple through holes 46 are provided on the outer side of the right mounting bracket 3, and mounting holes are provided inside the sliding mounting block 45. The outer side of the connecting rod 41 is locked with the mounting hole inside the sliding mounting block 45. The through holes 46 provide multiple locking positions for the connecting rod 41. By cooperating with different through holes 46, the position of the right mounting bracket 3 can be adjusted in multiple stages to meet the installation requirements of busbars of different widths. The outer side of the connecting rod 41 is slidably connected to the through holes. Inside 46, a sliding mounting block 45 is slidably connected to the front of the right mounting bracket 3. The sliding mounting block 45 can slide along the limiting groove 44 to assist in fixing the end of the busbar. By adjusting its position, it can adapt to the mounting hole positions of different busbars, thereby enhancing the flexibility of busbar installation. Multiple busbar mounting seats 5 are slidably connected to the outside of the left mounting bracket 1. The busbar mounting seats 5 are evenly distributed along the length of the left mounting bracket 1 and the right mounting bracket 3. The spacing can be adjusted according to the specifications of the busbar and the installation requirements. Its function is to directly support and fix the DC busbar, ensure a safe distance between the busbars, and at the same time realize the insulation support of the busbar. The outside of the busbar mounting seat 5 is slidably connected to the inside of the right mounting bracket 3.

[0037] The storage and installation mechanism 2 includes a folding assembly 21, which includes a slide rail 211. The slide rail 211 provides a sliding track for the sliding rod 212, restricting the movement direction of the sliding rod 212 and ensuring that it can only move along the length of the left mounting frame 1, providing stable guidance for the folding action. The sliding rod 212 is slidably connected inside the slide rail 211. The sliding rod 212 serves as the connection fulcrum of the folding assembly 21. One end is slidably connected to the left mounting frame 1, and the other end is rotatably connected to the rotating adjustment plate 213, transmitting the supporting force of the left mounting frame 1 to the rotating adjustment plate 213. The rotating adjustment plate 213 is rotatably connected to the outside of the sliding rod 212. During the folding process, the rotating adjustment plate 213 changes its angle by rotating, and in conjunction with the telescopic action of the telescopic plate 214, realizes the distance adjustment between the left mounting frame 1 and the right mounting frame 3, so that the right mounting frame 3 can move closer to the left mounting frame 1 for folding.

[0038] A telescopic plate 214 is slidably connected inside the rotating adjustment plate 213. The extension length of the telescopic plate 214 compensates for the distance change of the rotating adjustment plate 213 during rotation, ensuring that the folding assembly 21 can stably connect the left mounting bracket 1 and the right mounting bracket 3 in both unfolded and folded states. A connecting shaft 215 is rotatably connected to the outside of the telescopic plate 214, providing a rotation fulcrum for the telescopic plate 214, allowing it to rotate freely with the movement of the right mounting bracket 3, ensuring smooth folding action, and simultaneously transmitting the force of the right mounting bracket 3 to the folding assembly 21. The folding assembly 21 is opened on the outer rear side of the left mounting bracket 1. A mounting connecting block 22 is fixedly connected to the outer right side of the left mounting bracket 1. The mounting connecting block 22 consists of components such as a sliding latch 23 and a return spring 25. The mounting base is provided as an auxiliary connection point between the left mounting bracket 1 and the right mounting bracket 3. The mounting connection block 22 has a sliding locking rod 23 inside. When the left mounting bracket 1 and the right mounting bracket 3 are brought close together, the positioning locking rod 28 on the outside of the right mounting bracket 3 comes into contact with the locking groove 27 inside the mounting connection block 22. At this time, the sliding locking rod 23 locks the relative position of the left mounting bracket 1 and the right mounting bracket 3 by engaging with the mounting hole on the outside of the positioning locking rod 28. This, together with the position adjustment mechanism 4, forms a double lock, improving the reliability of the connection. The front side of the sliding locking rod 23 is fixedly connected to a pull plate 24. The pull plate 24 provides a force point for the operator to pull the sliding locking rod 23 to release the lock, making the adjustment operation of the left mounting bracket 1 and the right mounting bracket 3 more convenient.

[0039] A return spring 25 is sleeved on the outside of the sliding latch 23. The elastic force of the return spring 25 keeps the latch head of the sliding latch 23 locked in the slot 27, ensuring reliable locking and preventing accidental loosening. A limit plate 26 is fixedly connected to the outside of the sliding latch 23. The limit plate 26 is used to transmit the elastic force of the return spring 25 and limit the sliding stroke of the sliding latch 23, preventing it from completely disengaging from the mounting block 22, thus playing a limiting protection role. A slot 27 is opened on the outside of the mounting block 22, providing multiple slots for the positioning latch 28. The positioning is locked, and the positioning rod 28 cooperates with the left mounting bracket 1 and the right mounting bracket 3 to achieve multi-level positioning, which enhances the accuracy of adjustment. The positioning rod 28 is fixedly connected to the left side of the right mounting bracket 3. When the right mounting bracket 3 slides to the appropriate position, the end of the positioning rod 28 will be locked into the corresponding slot 27, which cooperates with the sliding rod 23 to form a double lock, ensuring that the relative position of the left mounting bracket 1 and the right mounting bracket 3 is stable. The outside of the positioning rod 28 is locked with the inside of the slot 27, and the outside of the positioning rod 28 has a slot.

[0040] Reference Figures 2 to 4 The external fixed connection of the sliding mounting block 45 is a busbar mounting seat 5. The busbar mounting seat 5 can move synchronously with the sliding mounting block 45 along the limiting slide groove 44 to realize flexible adjustment of the busbar installation position. At the same time, the sliding mounting block 45 provides stable support for the busbar mounting seat 5 to ensure that the busbar body 6 will not shake after installation. The external sliding connection of the busbar mounting seat 5 is to the outside of the right mounting bracket 3. The internal fixed connection of the busbar mounting seat 5 is to the busbar body 6. The busbar body 6 is a copper or aluminum busbar with excellent conductivity. It is fixed in the slot 27 on the top of the busbar mounting seat 5 by insulating bolts and keeps it insulated from the busbar mounting seat 5. The busbar body 6 is a key conductive component in the DC circuit, used to connect different electrical components and realize the collection and distribution of current.

[0041] The busbar body 6 is electrically connected to a capacitor 7. The function of the capacitor 7 is to absorb harmonics and surge currents in the busbar circuit, stabilize the DC voltage, reduce the impact of voltage fluctuations on electrical equipment, and improve the power factor of the circuit to ensure the stable operation of the entire DC system. The external sliding connection of the connecting rod 41 is inside the left mounting bracket 1, and the internal opening of the through hole 46 is outside the left mounting bracket 1. One end of the return spring 25 is fixedly connected to the inside of the mounting connection block 22, and the other end of the return spring 25 is fixedly connected to the outside of the limit plate 26.

[0042] Working principle: When the left mounting bracket 1 and the right mounting bracket 3 are brought closer together, the rotating adjustment plate 213 rotates outside the left mounting bracket 1 and the right mounting bracket 3. During the rotation, the sliding rod 212 at the top causes the rotating adjustment plate 213 to slide inside the slide groove 211, thereby bringing the left mounting bracket 1 and the right mounting bracket 3 closer together. During this process, the telescopic plate 214 retracts inside the rotating adjustment plate 213. At this moment, by pulling the pull plate 24, the pull plate 24 is pulled... The movable limiting plate 26 slides inside the mounting connecting block 22, thereby pressing the return spring 25 and creating space inside the mounting connecting block 22. This allows the positioning rod 28 outside the right mounting bracket 3 to lock with the mounting connecting block 22 outside the left mounting bracket 1. At this moment, by releasing the pull plate 24, the return spring 25 outside the sliding rod 23 rebounds, allowing the sliding rod 23 to lock with the inside of the positioning rod 28, thus achieving overall storage.

[0043] When adjusting the position of the busbar mounting base 5, by pulling the second pull plate 43, the second pull plate 43 causes the connecting rod 41 to slide inside the through hole 46, which in turn causes the mounting spring 42 on the outside of the connecting rod 41 to deform, causing the connecting rod 41 to separate from the busbar mounting base 5. This allows the position of the busbar mounting base 5 to be adjusted or disassembled and replaced. When the busbar mounting base 5 is adjusted to the appropriate position, by releasing the second pull plate 43, the mounting spring 42 rebounds, which then causes the connecting rod 41 to lock into place with the busbar mounting base 5, thereby achieving the position adjustment of the busbar mounting base 5.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
