Description

Technical Field

[0001] This invention relates to the field of energy storage cabinets, and more particularly to a layered pull-out maintenance frame for battery packs in energy storage cabinets. Background Technology

[0002] With the rapid development of new energy storage technologies, energy storage cabinets, as the core carriers of energy storage systems, are widely used in industrial and commercial energy storage, grid peak shaving, and new energy infrastructure. To improve space utilization and energy storage capacity, energy storage cabinets typically employ a multi-layered, dense layout to install battery packs. During long-term charging and discharging operations, battery packs are prone to problems such as abnormal temperature, performance degradation, and component damage, requiring regular maintenance, inspection, and replacement. The ease and safety of removing battery packs from the cabinet directly impacts the operating efficiency and maintenance costs of the energy storage system.

[0003] The existing battery pack installation structures of energy storage cabinets are mostly fixed embedded or simple bracket types. There is no dedicated guiding pull mechanism between the battery pack and the cabinet frame. During maintenance, the battery pack must be lifted or pried manually. Uneven force can easily cause the battery pack to shift, bump, or even damage the cells or connectors. Some pull-out structures only have simple slide rails without independent positioning, limiting and load-bearing auxiliary designs. Multiple battery packs cannot be moved out independently, which can easily cause interference during maintenance. In addition, the battery packs are prone to shaking and jamming during the removal process, which greatly reduces maintenance efficiency and also poses safety hazards.

[0004] Therefore, developing a battery pack installation frame for energy storage cabinets that enables stable, independent, and safe removal of battery packs to overcome the shortcomings of existing structures, such as inconvenience in removal, susceptibility to interference, and insufficient safety, has become an urgent problem to be solved in the industry.

[0011] Preferably, pulleys are fixedly connected to the bottom ends of the outer surfaces of the two threaded rods, and multi-rail pulleys are vertically rotatably connected to the upper surface of the movable seat and the rear of the two pulleys.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the layered pull-out maintenance frame for the battery pack of the energy storage cabinet provided by the present invention; Figure 2 for Figure 1 The diagram shows the structure of the independent pushing mechanism of the layered pull-out maintenance frame for the energy storage cabinet battery pack; Figure 3 for Figure 1 A schematic diagram of the transmission structure in the independent pushing mechanism of the layered pull-out maintenance frame for the energy storage cabinet battery pack; Figure 4 for Figure 1 The enlarged schematic diagram of section A is shown. A layered pull-out maintenance frame for an energy storage cabinet battery pack includes: a basic frame structure and multiple independent pull-out mechanisms 4; The basic frame structure includes multiple side frames 1 vertically arranged on both sides. Multiple horizontal supports 2 with L-shaped cross sections are horizontally fixedly connected to the inner surface of the multiple side frames 1 on the same side. The multiple horizontal supports 2 on both sides correspond to each other. The two corresponding horizontal supports 2 are located on the same horizontal plane. The multiple horizontal supports 2 form a multi-layer structure between the multiple side frames 1. Multiple independent pull-out mechanisms 4 are respectively arranged inside the multi-layer structure. The structures of the multiple independent pull-out mechanisms 4 are all the same. One of the independent pull-out mechanisms 4 includes a sliding plate 41 that is laterally slidably connected between two corresponding horizontal supports 2. The upper surface of the sliding plate 41 is provided with a push structure that can move along its length and clamp and push the battery pack. A push-pull handle 419 is laterally fixedly connected to the middle of the front end surface of the sliding plate 41.

[0021] The basic frame structure of the device consists of multiple side uprights 1 and multiple horizontal supports 2. This structure is fixedly installed inside the energy storage cabinet by welding to form a rectangular frame structure. Inside this structure, multiple horizontal supports 2 are used to divide the structure into a multi-layer structure with uniform spacing. An independent pull-out mechanism 4 that can be pulled out laterally is set between the two horizontal supports 2 at the bottom of each layer.

[0022] The battery pack is placed horizontally on the upper surface of the sliding plate 41 in the independent pull-out mechanism 4. When the battery pack needs maintenance, simply hold the push-pull handle 419 and pull the entire sliding plate 41 outward to pull out the battery pack together. This makes it more convenient to transfer the battery pack or operate it directly on the equipment.

[0023] The inner surfaces of multiple horizontal supports 2 are fixedly connected with guide rails 3, and the sliding plate 41 is slidably connected between two horizontal supports 2 via the guide rails 3 on both sides.

[0024] Connecting blocks 6 are fixedly connected to both sides of the front end of multiple sliding plates 41. Winding rollers 7 are provided on the upper surface of multiple connecting blocks 6. Fixing blocks 5 are fixedly connected to the inner surface of the two side uprights 1 at the front end and at the top of each layer of the multi-layer structure. Steel cables 8 are wound on the outer surface of multiple winding rollers 7. The other end of multiple steel cables 8 is fixedly connected to the lower surface of the corresponding fixing blocks 5.

[0025] The guide rail 3 makes the sliding plate 41 slide more smoothly. When the sliding plate 41 is pulled out to its maximum position, the steel cable 8 on the winding roller 7 will be taut and tensioned, which will support the sliding plate 41 and prevent it from tilting and falling off due to excessive extension, thus improving the overall stability of the device. When the sliding plate 41 has not reached its maximum extension position, the cross bracket 2 can also guide and limit it to a certain extent. At the same time, during this process, the operator usually maintains the grip of the push-pull handle 419 to prevent the sliding plate 41 from tilting. When it is necessary to operate the battery pack directly on the device, external equipment can be used to support it under the sliding plate 41 to improve the safety of maintenance operations.

[0026] The pushing structure includes a first transverse groove 42 formed in the middle of the upper surface of the sliding plate 41 along its length direction. A lead screw 43 is rotatably connected to the inside of the first transverse groove 42. A lead screw sleeve is threadedly connected to the outer surface of the lead screw 43. A movable seat 46 that is slidably connected to the upper surface of the sliding plate 41 and adapted to its width is fixedly connected to the upper surface of the lead screw sleeve. A pushing plate 47 adapted to its width is vertically fixedly connected to the front part of the upper surface of the movable seat 46.

[0027] When the battery pack needs to be moved, the lead screw 43 can be rotated. During its rotation, the lead screw sleeve moves along its length, which in turn moves the movable seat 46 and the push plate 47 on the upper surface of the movable seat 46. The battery pack placed on the upper surface of the sliding plate 41 can be pushed outward through the push plate 47, making the transfer of the battery pack more convenient, smooth and stable.

[0028] The upper surface of the sliding plate 41 is provided with multiple guide rollers 420. The multiple guide rollers 420 can transform the sliding friction of the battery pack into rolling friction, making the pushing of the battery pack smoother and more stable, and less prone to tilting or deviation.

[0029] The upper surface of the sliding plate 41 is provided with side transverse grooves 48 parallel to the first transverse groove 42 on both sides. The lower part of the front surface of the push plate 47 is fixedly connected to two lower clamping plates 49. The two lower clamping plates 49 extend into the interior of the two side transverse grooves 48 respectively. The front surface of the push plate 47 is provided with two through grooves 410 arranged along its height direction and corresponding to the positions of the two lower clamping plates 49 respectively. The interior of the two through grooves 410 is vertically rotatably connected to threaded rods 411. The outer surfaces of the two threaded rods 411 are respectively threadedly connected to threaded sleeves that are slidably connected to the interior of the two through grooves 410. The front surfaces of the two threaded sleeves are respectively fixedly connected to upper clamping plates 412 corresponding to the two lower clamping plates 49 respectively.

[0030] Anti-slip pads are provided on the upper surfaces of the two lower clamping plates 49 and the lower surfaces of the two upper clamping plates 412.

[0031] The battery pack placed on the sliding plate 41 can be clamped and fixed by two upper clamping plates 412 and a lower clamping plate 49. In actual operation, when the battery pack needs to be sent into the energy storage cabinet, the sliding plate 41 is first pulled outward. Then, the screw 43 is controlled to rotate, driving the push plate 47 to move to its most reachable front end. Then, the battery pack can be pushed in from the front end of the sliding plate 41 until the rear end of the battery pack contacts the front surface of the push plate 47. Then, the two threaded rods 411 are controlled to rotate, driving the two threaded sleeves on them to move down, and simultaneously driving the two upper clamping plates 412 to move down until the two upper clamping plates 412 are tightly attached to the upper surface of the battery pack. At this time, the battery pack can be fixed by friction. Then, the screw 43 is controlled to reverse. Under the clamping effect of this structure, the battery pack can be moved to the rear of the sliding plate 41, and finally the battery pack 41 is completely pulled above the sliding plate 41.

[0032] The upper surface of the lower clamping plate 49 is flush with the horizontal plane at the top of the multiple guide rollers 420, but it is still a certain distance higher because of the anti-slip pads on it. Combined with the two upper clamping plates 412 applying a downward force to the battery pack, the stable clamping of the battery pack can be ensured.

[0033] The upper surface of the sliding plate 41 is provided with a second transverse groove 44 on both sides, which is parallel to the first transverse groove 42. The interior of the two second transverse grooves 44 is fixedly connected with a guide rod 45 in the transverse direction. The outer surface of the two guide rods 45 is slidably connected with a guide block in the transverse direction. The upper surface of the two guide blocks is fixedly connected to the lower surface of the movable seat 46.

[0034] The two guide rods 45 are slidably connected to the guide blocks on their outer surfaces to guide and limit the movement of the movable seat 46, making the movement of the movable seat 46 smoother and more stable, and preventing any deviation or tilting.

[0035] The bottom of the outer surface of each of the two threaded rods 411 is fixedly connected to a pulley 413. The upper surface of the movable seat 46 and the rear of the two pulleys 413 are vertically rotatably connected to a multi-rail pulley 414. The upper rails of the two multi-rail pulleys 414 are connected by belt drive, and the lower rails of the two multi-rail pulleys 414 are respectively connected to the two pulleys 413 by belt drive.

[0036] A first motor 415 is horizontally fixedly connected to the middle of the rear end surface of the sliding plate 41. The output shaft of the first motor 415 rotatably passes through the sliding plate 41 and is fixedly connected to the rear end of the lead screw 43. An L-shaped device frame 416 is fixedly connected to the upper surface of the movable seat 46 and to one side of a multi-rail pulley 414. A second motor 417 is fixedly connected to the upper surface of the device frame 416. The output shaft of the second motor 417 rotatably passes through the device frame 416 and is fixedly connected to the top end of the multi-rail pulley 414.

[0037] When the first motor 415 is running, it controls the rotation of the lead screw 43, thereby controlling the movement of the push plate 47. When the second motor 417 is running, its output shaft drives a multi-rail pulley 414 to rotate, which in turn drives another multi-rail pulley 414 to rotate synchronously via a belt. Both motors drive two pulleys 413 to rotate via belts on their lower rails, so that the two pulleys 413 can rotate synchronously, which in turn keeps the two threaded rods 411 rotating synchronously.

[0038] Both the multi-track pulley 414 and the pulley 413 are synchronous pulleys, so slippage will not occur.

[0039] Reinforcing ribs 418 are fixedly connected to both sides of the upper surface of the movable seat 46 and between the push plate 47.

[0040] The reinforcing rib 418 between the movable seat 46 and the push plate 47 can enhance the structural stability between the two, thereby improving the structural strength of the push plate 47.

[0041] The working principle of the layered pull-out maintenance frame for battery packs in the energy storage cabinet provided by this invention is as follows: The basic frame structure of the device consists of a side support 1 and a horizontal support 2 welded and fixed inside the energy storage cabinet, forming a multi-layered, evenly spaced installation frame. Each layer is equipped with an independent pull-out mechanism 4. The battery pack is placed horizontally on the upper surface of the sliding plate 41. During maintenance, the operator holds the push-pull handle 419 and can smoothly pull the sliding plate 41 outward along the guide rail 3 on the inner side of the horizontal support 2, so that the battery pack is moved out of the energy storage cabinet along with it. When the sliding plate 41 is pulled out to its maximum position, the steel cable 8 wound by the winding roller 7 on the connecting block 6 will be tightened and straightened by the fixing block 5, providing reliable support for the sliding plate and preventing it from falling or tilting. When it is necessary to clamp and position the battery pack, the first motor is used first. The first motor 415 drives the lead screw 43 to rotate, causing the movable seat 46 and the push plate 47 to move to the front end. After the battery pack is pushed in and in contact with the push plate, the second motor 417 is started. Through the synchronous transmission of the multi-rail pulley 414 and pulley 413, the threaded rods 411 on both sides rotate synchronously, causing the upper clamping plate 412 to move downward. Together with the lower clamping plate 49, the battery pack is stably clamped. Then, the first motor is controlled to reverse, so that the battery pack can be smoothly pulled back to the top of the sliding plate to complete the reset. When it is necessary to remove and transfer the battery pack, the first motor is driven again to drive the lead screw to rotate. The battery pack is smoothly pushed outward along the guide roller 420 through the push plate. The whole process is simple to operate and smooth to move, and can realize the safe, efficient and stable pulling, clamping, pushing and maintenance of the battery pack.

[0042] Compared with related technologies, the layered pull-out maintenance frame for energy storage cabinet battery packs provided by this invention has the following beneficial effects: This invention adopts a layered independent pull-out frame structure, combined with a dedicated guide rail 3 and a stable load-bearing design, enabling each layer of battery packs in the energy storage cabinet to be moved out independently, smoothly, and stably through an independent pull-out mechanism 4. This completely solves the problems of existing battery packs being difficult to remove from the energy storage cabinet, easily getting stuck, and easily shifting. During maintenance, there is no need for manual forceful lifting or prying of the battery packs; simply push and pull the handle 419 to smoothly pull the battery pack out along with the sliding plate 41. This effectively avoids battery pack collisions, cell damage, and connector damage caused by uneven force, significantly improving the convenience and safety of battery pack maintenance operations. Simultaneously, the automatic clamping and pushing mechanism set in this invention can... The push plate 47, upper clamping plate 412, and lower clamping plate 49 stably clamp the battery pack, and together with the lead screw 43 and movable seat 46, they achieve precise pushing, ensuring that the battery pack remains centered, stable, and does not deviate during the pulling and resetting process, further improving operational stability and equipment lifespan. The multi-layer independent pulling mechanism allows for individual maintenance of each battery pack layer without interference. Combined with the auxiliary load-bearing and anti-fall structure of the steel cable 8, winding roller 7, and fixing block 5, it effectively avoids the safety risks and space conflicts caused by simultaneous operation of multiple battery packs, significantly improving maintenance efficiency, reducing operational difficulty and labor intensity, and effectively extending the service life of the battery pack and energy storage cabinet. It also improves the stability, safety, and economy of the energy storage system, demonstrating strong practicality and broad market application prospects.
