Description

Technical Field

[0001] The present invention relates to the technical field of power distribution equipment, and particularly to a modular UPS integrated power distribution equipment. Background Art

[0002] A UPS is an uninterruptible power supply containing an energy storage device. It connects the energy storage device to the host, and through module circuits such as the host inverter, it converts direct current into alternating current. It has three basic functions: voltage regulation, filtering, and uninterruptibility. It is mainly used to provide stable and uninterruptible power supply for a single computer, a computer network system, or other power electronic devices such as solenoid valves and pressure transmitters. Nowadays, there are more and more important temporary activities, and the demand for temporary guarantee equipment is increasing year by year. Similarly, the power guarantee demand is also diverse. The UPS can provide uninterruptible power supply, which is one of the important factors to ensure the normal and stable operation of equipment, to meet the power supply requirements of sensitive loads, so that the lower-level users cannot feel a power outage and achieve zero flicker and zero perception.

[0003] Traditional UPSs are large in volume and low in efficiency. By modularly installing the UPS and using high-frequency technology to divide it into multiple power modules, each module outputs in parallel, with high operating efficiency. Installed nearby the equipment, it improves the reliability of the UPS power supply. However, the existing modular UPS power distribution equipment presents in an overall combined mode, resulting in a large occupied space. And the battery pack is usually installed in the power distribution equipment in a pull-out manner, which is not convenient to adjust the storage space according to the number of battery modules. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a modular UPS integrated power distribution equipment to solve the problems raised in the above background art. The structure of the present invention is novel. By means of a limiting component and a driving component, the space inside the battery box is adjusted, so that the installed battery pack can move synchronously, which is convenient for installing and disassembling the battery pack according to needs. Keeping the distance between each layer of battery packs the same all the time helps the air circulation and makes full use of the space inside the battery box.

[0005] To achieve the above object, the present invention is implemented by the following technical solutions: A modular UPS integrated power distribution device, including a main chassis, on one side of the main chassis, multiple battery boxes are spliced and installed, and a control box is fixed on the top of the battery box. A cabinet door is rotatably installed on the front of the battery box, and a wire trough is provided on the back of the battery box. A limiting component is arranged inside the battery box.

[0006] Further, the limiting component further includes a vertical plate. A vertical plate is fixed on the surface of the inner wall of the battery box between the front vertical beam and the rear vertical beam, and the cross plate is slidably sleeved on the surface of the vertical plate.

[0007] Further, a moving notch is provided on the surface of the cross plate between the two vertical plates. The bottom of the moving notch is rotatably connected to the connecting rod, and a socket is fixed at the top of the moving notch. A plug post is rotatably installed on the outside of the connecting rod at the upper end of the connecting shaft, and the plug post is slidably inserted into the socket of the upper group of installation plates.

[0008] Further, first convex strips are fixed on the inner side surfaces of the front vertical beam and the rear vertical beam, and both ends of the cross plate slide along the first convex strips. The first convex strips are made of elastic rubber material. Pulley wheels are equidistantly installed on both sides of the installation plate, and the pulley wheels slide along the inner side of the cross plate.

[0009] Further, a semi-circular clamping frame is fixed on the back of the connecting shaft. The semi-circular clamping frame is sleeved on the surface of the vertical rod. A second locking bolt is threadedly inserted on the outside of the semi-circular clamping frame, and the second locking bolt is in pressing contact with the vertical rod.

[0010] Further, on one side of the bottom of the front and rear ends of the installation plate, an insertion plate is provided, and on the other side of the bottom of the installation plate, a storage plate is provided. The insertion plate is slidably inserted into the storage plate. The other ends of the insertion plate and the storage end are fixed to the bottom of the cross plate. A first locking bolt is threadedly inserted at the port of the storage plate.

[0011] Further, the driving component further includes an inclined plate. The inclined plates are fixed to the tops of both sides of the battery box. A sliding block is slidably connected to the bottom inclined surface of the inclined plate, and the bottom of the sliding block is fixedly connected to the top of the vertical rod. A second convex strip is fixed to the inclined surface of the inclined plate, and the sliding block slides along the second convex strip.

[0012] Further, a fixing plate is fixed between the two sliding blocks, and a bidirectional electric push rod is fixed to the surface of the fixing plate. The extending end of the bidirectional electric push rod slidably passes through the sliding block and is fixed with a friction block.

[0013] Further, two first electric push rods are symmetrically and rotatably connected to the inner wall of the top of the front end of the battery box through a rotating shaft, and the extending ends of the first electric push rods are rotatably connected to the fixing plate through a rotating shaft.

[0014] Further, a plug rod is slidably inserted into the bottom of the vertical rod, and the bottom of the plug rod slides along the inner wall of the bottom of the battery box. A return spring is sleeved on the surface of the plug rod, and both ends of the return spring are fixedly connected to the vertical rod and the bottom of the plug rod.

[0015] Advantages of the present invention:

[0016] 1. The cross plate of the present invention is snap-fitted and installed between the front vertical beam and the rear vertical beam, and slides along the vertical plate. Both sides of the mounting plate are connected to the cross plate through pulleys. A groove for the pulley to slide is provided on the inner side of the cross plate, and the front end of the groove is flush with the front vertical beam. Thus, the mounting plate and the battery pack can be slid out separately along the groove of the cross plate for maintenance of the battery pack.

[0017] 2. The present invention installs the cross plate between the front vertical beam and the rear vertical beam through the telescopic insertion plate and the receiving plate. The first convex strips of the front vertical beam and the rear vertical beam are made of rubber material. The two ends of the cross plate can be snap-fitted on the first convex strips by extrusion. Then, the length of the insertion plate and the receiving plate is fixed by the first locking bolt to keep the position of the cross plate unchanged. There are connecting shafts at both ends of the cross plate. One of the connecting shafts is rotatably connected to the cross plate through a connecting rod. During installation, the cross plate is placed between the front vertical beam and the rear vertical beam. The semi-circular clamping frame is sleeved on the surface of the vertical rod and fixed by the second locking bolt to keep the locking connection between the connecting shaft and the vertical rod. The upper cross plate is inserted into the connecting rod insertion post at the upper end of the connecting shaft of the lower layer through the socket to form an integral structure, which is convenient for unified movement.

[0018] 3. When the sliding block slides upward in the present invention, the connecting shaft will also increase the distance between adjacent two groups of battery packs through the connecting rod, so as to keep the same air circulation capacity between the two groups of battery components. After determining the position, the extending end of the bidirectional electric push rod passes through the sliding block to drive the friction block to be in frictional contact with the inner wall of the battery box, so as to fix the position of the vertical rod, and the bottom of the vertical rod is limited by the plug rod.

[0019] 4. Through the first electric push rod, the present invention can push the fixed plate and two inclined blocks to slide along the inclined plane of the inclined plate. As the inclined blocks slide along the inclined plane of the inclined plate, the vertical rod gradually descends and sleeves on the surface of the bottom insertion rod. The semi-circular clamping frame connected to the vertical rod will move backward synchronously and descend a certain height. Furthermore, through the connecting shaft and two connecting rods, the mounting plate and the battery pack of the upper and lower components are pulled to gather, thereby shortening the distance between adjacent two layers of battery packs. Because there are connecting shafts and connecting rods between each layer and the bottom mounting plate and battery pack are used as fixed points, the distance between each layer is adjusted synchronously and the adjusted dimensions are the same, always maintaining the same distance between adjacent two groups of battery packs, avoiding chaos in the internal storage space, and at the same time giving space for installing new battery packs at the uppermost end, uniformly adjusting the installed battery packs, which is convenient for installation.

[0020] 5. Compared with the prior art, the present invention adjusts the space inside the battery box through the limiting component and the driving component, enabling the installed battery packs to move synchronously, facilitating the installation and disassembly of the battery packs according to requirements. Keeping the distance between each layer of battery packs always the same helps the air circulation and makes full use of the internal space of the battery box. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Please refer to Figures 1 to 10, the present invention provides a technical solution: a modular UPS integrated power distribution device, including a main chassis 1, on one side of the main chassis 1, multiple battery boxes 2 are spliced and installed, and a control box 21 is fixed on the top of the battery box 2. A box door 22 is rotatably installed on the front of the battery box 2, and a wire trough 23 is provided on the back of the battery box 2. A limiting component 4 is arranged inside the battery box 2. The limiting component 4 includes a rear vertical beam 41. The rear vertical beams 41 are fixed on both sides of the rear end inside the battery box 2, and the front vertical beams 42 are fixed on both sides of the front end inside the battery box 2. Mounting plates 3 are equidistantly installed inside the front vertical beam 42 and the rear vertical beam 41. A battery pack 31 is fixed on the top of the mounting plate 3, and cross plates 32 are slidably connected to both sides of the mounting plate 3. The cross plates 32 slide between the front vertical beam 42 and the rear vertical beam 41. Connecting shafts 45 are arranged on both sides of the mounting plate 3, and two connecting rods 46 are symmetrically and rotatably connected to the connecting shafts 45. The connecting rod 46 at the lower end of the connecting shaft 45 is rotatably connected to the cross plate 32 through a rotating shaft. A driving component 5 is arranged on the top of the battery box 2. The driving component 5 includes a vertical rod 44. The vertical rod 44 slides along the side wall of the battery box 2, and the vertical rod 44 is slidably inserted on the connecting shaft 45. Four support columns 24 are fixed on the bottom of the battery box 2, and the support columns 24 are fixed to the mounting plate 3 at the bottommost layer of the battery box 2. In this solution, the usage methods of the main chassis 1, the control box 21, and the battery pack 31 are the same as those of the existing UPS integrated power distribution technology. When using the device, multiple battery boxes 2 are installed on the side plate of the main chassis 1 as needed, and multiple battery packs 31 are installed inside the battery box 2. The bottom of the battery pack 31 is supported by the mounting plate 3. When a new battery pack 31 needs to be added, the driving component 5 and the limiting component 4 cooperate to adjust the positions of the installed battery packs 31 so that they synchronously descend, keeping the distance between each battery pack 31 the same, which is beneficial to air flow and avoids the spatial disorder inside the battery box 2.

[0034] In this embodiment, the limiting component 4 further includes a vertical plate 43. The vertical plate 43 is fixed on the inner wall surface of the battery box 2 between the front vertical beam 42 and the rear vertical beam 41 at the front end. The transverse plate 32 is slidably sleeved on the surface of the vertical plate 43. First ridges 47 are fixed on the inner side surfaces of the front vertical beam 42 and the rear vertical beam 41. The two ends of the transverse plate 32 slide along the first ridges 47. The first ridges 47 are made of elastic rubber. Pulley 34 are equidistantly installed on both sides of the mounting plate 3. The pulley 34 slides along the inner side of the transverse plate 32. On one side of the bottom of the front and rear ends of the mounting plate 3, there is a plug board 35. On the other side of the bottom of the mounting plate 3, there is a receiving board 36. The plug board 35 is slidably inserted into the inside of the receiving board 36. The other ends of the plug board 35 and the receiving end are fixedly connected to the bottom of the transverse plate 32. A first locking bolt 37 is threadedly inserted at the port of the receiving board 36. The transverse plate 32 is clamped and installed between the front vertical beam 42 and the rear vertical beam 41 and slides along the vertical plate 43. Among them, both sides of the mounting plate 3 are connected to the transverse plate 32 through the pulley 34. A groove for the pulley 34 to slide is opened on the inner side of the transverse plate 32. The front end of the groove is flush with the front vertical beam 42. Thus, the mounting plate 3 and the battery pack 31 can be separately slid out along the groove of the transverse plate 32 to repair the battery pack 31.

[0035] In this embodiment, a moving notch 33 is opened on the surface of the transverse plate 32 between the two vertical plates 43. The bottom of the moving notch 33 is rotatably connected to the connecting rod 46. A socket 410 is fixed at the top of the moving notch 33. A plug post 49 is rotatably installed on the outside of the connecting rod 46 at the upper end of the connecting shaft 45. The plug post 49 is slidably inserted into the socket 410 of the upper mounting plate 3. A semi-circular clamping frame 48 is fixed on the back of the connecting shaft 45. The semi-circular clamping frame 48 is sleeved on the surface of the vertical rod 44. A second locking bolt 411 is threadedly inserted on the outside of the semi-circular clamping frame 48. The second locking bolt 411 is in pressing contact with the vertical rod 44. The moving notch 33 is opened for the convenience of the rotation of the connecting shaft 45 and the connecting rod 46 and the movement of the vertical rod 44. Before installing the battery pack 31, the transverse plate 32 is installed between the front vertical beam 42 and the rear vertical beam 41 through the telescopic property of the plug board 35 and the receiving board 36. Among them, the first ridges 47 of the front vertical beam 42 and the rear vertical beam 41 are made of rubber. The two ends of the transverse plate 32 can be clamped on the first ridges 47 by extrusion. Subsequently, the length of the plug board 35 and the receiving board 36 is fixed through the first locking bolt 37 to keep the position of the transverse plate 32 unchanged. There are connecting shafts 45 at both ends of the transverse plate 32. One of the connecting shafts 45 is rotatably connected to the transverse plate 32 through the connecting rod 46. When installing, the transverse plate 32 is placed between the front vertical beam 42 and the rear vertical beam 41. The semi-circular clamping frame 48 is sleeved on the surface of the vertical rod 44 and fixed through the second locking bolt 411 to keep the locking connection between the connecting shaft 45 and the vertical rod 44. The transverse plate 32 on the upper layer is inserted into the plug post 49 of the connecting rod 46 at the upper end of the connecting shaft 45 of the lower layer through the socket 410 to form an integral structure.

[0036] In this embodiment, the driving assembly 5 further includes an inclined plate 51. The inclined plates 51 are fixed to the tops of both sides of the battery box 2. A sliding block 52 is slidably connected to the bottom inclined surface of the inclined plate 51, and the bottom of the sliding block 52 is fixedly connected to the top of the vertical rod 44. A second rib 56 is fixed to the inclined surface of the inclined plate 51, and the sliding block 52 slides along the second rib 56. A fixing plate 53 is fixed between the two sliding blocks 52, and a bidirectional electric push rod 55 is fixed to the surface of the fixing plate 53. The extending end of the bidirectional electric push rod 55 slidably passes through the sliding block 52 and is fixed with a friction block 57. Two first electric push rods 54 are symmetrically and rotatably connected to the inner wall of the top front end of the battery box 2 through a rotating shaft, and the extending ends of the first electric push rods 54 are rotatably connected to the fixing plate 53 through a rotating shaft. The bottom of the vertical rod 44 is slidably inserted with a plug rod 412, and the bottom of the plug rod 412 slides along the inner wall of the bottom of the battery box 2. A return spring 413 is sleeved on the surface of the plug rod 412, and both ends of the return spring 413 are fixedly connected to the vertical rod 44 and the bottom of the plug rod 412. The first electric push rod 54 can push the fixing plate 53 and the two sliding blocks 52 to slide along the inclined surface of the inclined plate 51. The first electric push rod 54 adjusts its angle by itself through the rotating shaft to cope with the movement path of the sliding block 52. During this process, the sliding block 52 slides along the inclined surface of the inclined plate 51, so that the vertical rod 44 gradually descends and is sleeved on the surface of the bottom plug rod 412. The semi-circular clamping frame 48 connected to the vertical rod 44 will move backward synchronously and descend a certain height. Furthermore, the mounting plate 3 and the battery pack 31 of the upper and lower components are pulled together through the connecting shaft 45 and the two connecting rods 46, thereby shortening the distance between adjacent two layers of battery packs 31. Because there are connecting shafts 45 and connecting rods 46 between each layer, and the bottom mounting plate 3 and battery pack 31 are used as fixed points, the distance between each layer is adjusted synchronously, and the adjusted dimensions are the same, always maintaining the same distance between adjacent two groups of battery packs 31, avoiding the chaos of the internal storage space, and at the same time giving space for installing new battery packs 31 at the uppermost end, uniformly adjusting the installed battery packs 31, which is convenient for installation. When the sliding block 52 slides upward, the connecting shaft 45 will increase the distance between adjacent two groups of battery packs 31 through the connecting rod 46, keeping the same air circulation capacity between the two groups of battery packs 31. After determining the position, the extending end of the bidirectional electric push rod 55 passes through the sliding block 52 to drive the friction block 57 to be in frictional contact with the inner wall of the battery box 2, realizing the fixation of the position of the vertical rod 44. The bottom of the vertical rod 44 is limited by the plug rod 412.

[0037] When using the device, install multiple groups of battery boxes 2 on the side plate of the main chassis 1 as needed. Install multiple groups of battery packs 31 inside the battery box 2. The bottom of the battery pack 31 is supported by the mounting plate 3. When a new battery pack 31 needs to be added, the first electric push rod 54 can push the fixed plate 53 and two inclined blocks 52 to slide along the inclined surface of the inclined plate 51. The first electric push rod 54 adjusts its angle by itself to cope with the movement path of the inclined block 52. During this process, the inclined block 52 slides along the inclined surface of the inclined plate 51, causing the vertical rod 44 to gradually lower and sleeve on the surface of the bottom plug rod 412. The semi-circular clamping frame 48 connected to the vertical rod 44 will move backward synchronously and descend a certain height. Then, through the connecting shaft 45 and two connecting rods 46, the mounting plate 3 and the battery pack 31 of the upper and lower components are pulled together, thereby shortening the spacing between adjacent layers of battery packs 31. Because there are connecting shafts 45 and connecting rods 46 between each layer, and the bottom mounting plate 3 and battery pack 31 are used as fixed points, the spacing between each layer is adjusted synchronously, and the adjusted dimensions are the same, always maintaining the same spacing between adjacent two groups of battery packs 31, avoiding chaos in the internal storage space, and at the same time giving space for installing a new battery pack 31 at the topmost end, uniformly adjusting the installed battery packs 31, which is convenient for installation. When the inclined block 52 slides upward, the connecting shaft 45 will increase the distance between adjacent two groups of battery packs 31 through the connecting rod 46, maintaining the same air circulation capacity between the two battery packs 31. After determining the position, the extended end of the bidirectional electric push rod 55 passes through the inclined block 52 to drive the friction block 57 to be in frictional contact with the inner wall of the battery box 2, realizing the fixation of the position of the vertical rod 44. The bottom of the vertical rod 44 is limited by the plug rod 412. Before installing the battery pack 31, the cross plate 32 is installed between the front vertical beam 42 and the rear vertical beam 41 in a telescopic manner through the plug plate 35 and the receiving plate 36. The first convex strips 47 of the front vertical beam 42 and the rear vertical beam 41 are made of rubber, and the two ends of the cross plate 32 can be clamped on the first convex strips 47 by extrusion. Then, the length of the plug plate 35 and the receiving plate 36 is fixed by the first locking bolt 37 to keep the position of the cross plate 32 unchanged. There are connecting shafts 45 at both ends of the cross plate 32. One of the connecting shafts 45 is rotatably connected to the cross plate 32 through the connecting rod 46. During installation, the cross plate 32 is placed between the front vertical beam 42 and the rear vertical beam 41. The semi-circular clamping frame 48 is sleeved on the surface of the vertical rod 44 and fixed by the second locking bolt 411 to keep the locking connection between the connecting shaft 45 and the vertical rod 44. The upper cross plate 32 is inserted into the plug post 49 of the connecting rod 46 at the upper end of the connecting shaft 45 of the lower layer through the socket 410 to form an integral structure.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
