Description

TECHNICAL FIELD

[0002] The statements herein are provided only to complement the background of the present application and are not necessarily prior art.

[0003] In modern data processing centers, communication base stations, and industrial automation control systems, uninterruptible power supply (UPS) systems play an increasingly critical role. Its core responsibility is to quickly and seamlessly take over power supply during a sudden power supply failure, fully protect critical equipment from power outages, maintain stable and continuous operation, and then uninterruptably output power. In current technical practice, most uninterruptible power supply cabinets widely adopt the layout scheme of "multiple UPS power modules arranged compactly and densely": Specifically, a large number of UPS power modules are arranged in layers along the height direction of the cabinet, with only a very small gap between them to meet the basic electrical safety specifications. The initial design aims to maximize space utilization.

[0004] However, given that UPS power modules internally integrate transformers, reactors, power semiconductor devices, and large-capacity electrolytic capacitors, among many other key electrical components, the weight of a single module generally exceeds 30 kilograms, and some high-power output models can reach 50 kilograms or even higher. When performing maintenance work, maintenance personnel must first pull the faulty module out of the cabinet along the guide rail, then manually transfer it to the ground or a specially built maintenance platform, and then carry out further disassembly and maintenance operations. Throughout the process, maintenance personnel have to repeatedly lift the heavy module, which not only significantly increases labor intensity, but also easily causes accidental collisions in the already cramped and narrow work channel, which may cause additional physical damage to the module.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. The embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0017] Please refer to Figures 1-13 The present application discloses a kind of modular uninterruptible power supply structure, comprising: Cabinet 1, the x-axis direction both sides of cabinet 1 are provided with maintenance opening communicated with the inside of cabinet 1; Multiple brackets 2 are arranged in cabinet 1 and are detachably connected with cabinet 1; Multiple UPS modules 3 correspond to multiple brackets 2, each UPS module 3 can be placed on the top of corresponding bracket 2 and slide towards or away from the side of maintenance opening, and can be detachably connected with cabinet 1; First cover door 4 is rotatably arranged on one side of the x-axis direction of cabinet 1, and is detachably connected with cabinet 1, first cover door 4 is used to block adjacent maintenance opening; The guide rail assembly 5 comprises a stand 51 and a second cover door 52 arranged on the other side of the cabinet 1 in the axial direction, the stand 51 and the second cover door 52 are respectively located on both sides of the moving direction of the UPS module 3, a plurality of first guide rails 53 corresponding to each UPS module 3 are detachably arranged on the stand 51, a plurality of second guide rails 54 corresponding to each UPS module 3 are detachably arranged on the second cover door 52, the first guide rail 53 and the second cover door 52 can rotate around the r-axis of the cabinet 1, when the first guide rail 53 rotates into the corresponding maintenance opening, the second cover door 52 can rotate to block the corresponding maintenance opening, when the first guide rail 53 and the second cover door 52 rotate to be perpendicular to the cabinet 1, the corresponding UPS module 3 can slide from the bracket 2 to the second guide rail 54 and the first guide rail 53.

[0018] According to the present application, when any UPS module 3 needs to be taken out for maintenance, the UPS module 3 can be pulled from the bracket 2 to the first guide rail 53 and the second guide rail 54 for maintenance, and after maintenance, the UPS module 3 is pushed back to the bracket 2 and fixed to the cabinet 1, and the first guide rail 53 and the second cover door 52 can be flipped and stored after maintenance, thereby achieving the purpose of convenient maintenance.

[0019] It should be noted that the maintenance opening of the UPS module 3 is located at the top of the UPS module 3, and before the UPS module 3 is slid out, the first cover door 4 needs to be opened, the cable connected to the UPS module 3 is separated, and then the sliding operation is performed.

[0020] In an embodiment, the stand 51 is a hollow channel steel with one side open, the opening of the stand 51 is located on the side of the stand 51 close to the maintenance opening, the first guide rail 53 comprises a first clamping plate 531 arranged at the opening of the stand 51 and capable of sliding up and down, the first clamping plate 531 is provided with a lateral baffle 532 capable of rotating around the r-axis of the cabinet 1, the lateral baffle 532 is provided with a supporting plate 533 for supporting the corresponding UPS module 3, the opening of the stand 51 is further provided with a second clamping plate 55 capable of sliding up and down, the first clamping plate 531 and the second clamping plate 55 are detachably connected with the stand 51, and the first clamping plate 531 is provided with a first locking part for locking the lateral baffle 532 when the lateral baffle 532 rotates into the maintenance opening or the lateral baffle 532 rotates to be perpendicular to the cabinet 1.

[0021] With this design, since the first guide rail 53 is connected to the column 51 through the first fastening plate 531, and the column 51 can also be detachably connected to the second fastening plate 55, the installation position of the first guide rail 53 can be adjusted according to the installation position of the UPS module 3. The remaining positions where the UPS module 3 is not installed can be filled by the second fastening plate 55, so that the first guide rail 53 can also be modularly adjusted according to the position of the UPS module 3. At the same time, since the opening of the column 51 is filled by the first fastening plate 531 and the second fastening plate 55, the support strength of the column 51 can be improved.

[0022] In one embodiment, the first locking component includes two first pivot seats 534 disposed on the first fastening plate 531 and located on the upper and lower sides of the side baffle 532. Each of the upper and lower sides of the side baffle 532 is provided with a first pivot 535 penetrating the adjacent first pivot seat 534. A limiting ring 536 is provided at the bottom of the lower first pivot seat 534, sleeved on the outside of the corresponding first pivot 535. The top end of the limiting ring 536 is inserted into the corresponding first pivot seat 534 and can move up and down. The limiting ring 536 and the first pivot seat... A first compression spring (not shown in the figure) is provided between 534. A positioning rod 537 is provided on the lower first rotating shaft 535, which passes through the limiting ring 536. The limiting ring 536 is provided with two slots for the positioning rod 537 to be engaged when the side baffle 532 is rotated into the maintenance port or when the side baffle 532 is rotated to be perpendicular to the cabinet 1. When the first compression spring is in the natural state, the positioning rod 537 is located in one of the slots. When the first compression spring is in the fully compressed state, the limiting ring 536 is located at the top of the positioning rod 537.

[0023] This design allows for adjustment of the rotation angle of the first guide rail 53. By pushing the limit ring 536 upward, the positioning rod 537 can be moved out of the slot. Then, the side baffle 532 can be rotated into the maintenance port or perpendicular to the cabinet 1. After releasing the limit ring 536, it can be reset under the push of the first compression spring, allowing the positioning rod 537 to re-enter the slot. This completes the rotation restriction of the side baffle 532, ensuring that the side baffle 532 can maintain the required position in both working states.

[0024] In one embodiment, the column 51 is provided with an air guide pipe communicating with the inner cavity of the column 51. The end of the air guide pipe away from the column 51 is connected to an air filtration device. The first fastening plate 531 is provided with an air inlet communicating with the inside of the column 51. The side baffle 532 is provided with an air guide channel. A corrugated hose 538 for communicating the air inlet with the air guide channel is provided between the side baffle 532 and the first fastening plate 531. When the side baffle 532 is rotated into the maintenance port, the corresponding UPS module 3 can draw air from the air guide channel for heat dissipation. The first cover 4 is provided with multiple exhaust holes for dissipating heat-dissipating gases.

[0025] This design allows the first guide rail 53 to not only support the corresponding UPS module 3 to slide out for maintenance, but also to provide clean cooling air to the corresponding UPS module 3 during normal operation through the cooperation of the air filtration equipment, the column 51 and the first guide rail 53.

[0026] In practice, refrigeration equipment can be added to cool the air after it has been filtered by the air filtration equipment, thereby improving the heat dissipation effect.

[0027] It should be noted that refrigeration equipment and air filtration equipment are common knowledge in this field, so their specific structural components and working principles will not be elaborated on in this article.

[0028] In one embodiment, the cabinet 1 is provided with an adjustment component 6 for moving the second cover 52 up and down when the second cover 52 is rotated; The adjustment assembly 6 includes two second pivot seats 61 disposed on the cabinet 1 and located on the upper and lower sides of the second cover 52 respectively. The upper and lower sides of the second cover 52 are provided with second pivots 62 that pass through the corresponding second pivot seats 61. The upper second pivot 62 is provided with guide beads 63 that are inserted into the corresponding second pivot seat 61. The upper second pivot seat 61 is provided with a spiral guide groove to guide the movement of the guide beads 63. When the second cover 52 is rotated to be perpendicular to the cabinet 1, the second guide rail 54 is at the same height as the corresponding first guide rail 53. When the second cover 52 is rotated to block the maintenance opening, the second guide rail 54 is located below the corresponding first guide rail 53.

[0029] This design allows the second cover 52 to rotate and adjust its angle, while simultaneously moving the second guide rails 54 mounted on it up and down. When the second cover 52 rotates to be perpendicular to the cabinet 1, the second guide rails 54 and the corresponding first guide rails 53 are at the same height, which will not affect the normal sliding out of the corresponding UPS module 3. Furthermore, when the second cover 52 rotates to block the maintenance opening, the second guide rails 54 are located below the corresponding first guide rails 53, so they will not collide with the existing first guide rails 53 during rotation, ensuring that both the second guide rails 54 and the first guide rails 53 can be properly stored.

[0030] In one embodiment, the second cover 52 is provided with a mounting bracket 7 for mounting multiple second guide rails 54. The mounting bracket 7 includes two fixed beams 71 disposed on the second cover 52, and two fixed posts 72 disposed between the two fixed beams 71. Multiple fastening components are disposed on the fixed posts 72. The fastening components include a fixed collar 73 fixedly disposed on the fixed post 72 and a movable collar 74 threadedly connected to the fixed post 72 and located at the top of the fixed collar 73. The fixed collar 73 and the movable collar 74 have the same outer diameter. The bottom of the movable collar 74 is provided with a fastening collar 75 with an outer diameter smaller than the outer diameter of the movable collar 74. The second guide rail 54 is provided with a through hole for inserting the fastening collar 75 and a insertion groove for the fixed post 72 to enter and exit the through hole.

[0031] This design allows for quick installation and fixation of the second guide rail 54. By first rotating the movable collar 74 upwards to align the insertion slot on the corresponding second guide rail 54 with the fixing post 72, the second guide rail 54 is pushed for installation. Once the fixing post 72 is inside the through hole, the movable collar 74 is rotated downwards to engage the locking collar 75 within the through hole. Due to the restriction of the locking collar 75, the second guide rail 54 cannot be separated from the fixing post 72, thus completing the quick installation and fixation of the second guide rail 54. This also allows the second guide rail 54 to be modularly installed according to the position of the UPS module 3.

[0032] In one embodiment, the second cover 52 is provided with a second locking component 8 for locking the second cover 52 when the second cover 52 is rotated to be perpendicular to the cabinet 1 or when the second cover 52 is rotated to block the maintenance opening; The second locking component 8 includes an insert plate 81 slidably disposed on the second cover 52 and a guide sleeve 82 fixed on the second cover 52. The guide sleeve 82 is sleeved on the outside of the insert plate 81 and is used to guide the insert plate 81 to slide towards or away from the cabinet 1. A spring mounting seat 83 is fixedly disposed on the insert plate 81. The spring mounting seat 83 is located on the side of the guide sleeve 82 that is close to the cabinet 1. A second compression spring 84 is disposed between the spring mounting seat 83 and the guide sleeve 82. The cabinet 1 is respectively provided with two slots for the insert plate 81 to be inserted when the second cover 52 is rotated to be perpendicular to the cabinet 1 or when the second cover 52 is rotated to block the maintenance opening. When the second compression spring 84 is in its natural state, the insert plate 81 is inserted into the slot.

[0033] This design allows the second cover 52 to rotate and adjust its angle normally by pulling the insert plate 81 out of the slot. After adjusting to the desired working position, the second compression spring 84 can push the insert plate 81 into the corresponding slot to restrict the second cover 52 from continuing to rotate, thus ensuring that the second cover 52 can maintain the desired position in both working states.

[0034] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
