Description

Technical Field

[0001] This utility model relates to the field of battery energy storage technology, and in particular to a battery pack clustering device. Background Technology

[0002] With the increasing global demand for renewable energy and the intelligent development of power systems, energy storage devices are playing an increasingly important role in energy management. Energy storage devices can not only effectively balance electricity supply and demand and improve the stability and reliability of the power grid, but also significantly improve energy efficiency and reduce carbon emissions. In recent years, energy storage technology has made great strides, especially battery energy storage technology, whose application scope has been continuously expanding, covering all levels from residential users to industrial applications.

[0003] A battery pack is the most important component of a battery energy storage device, consisting of multiple individual battery cells. For example, the commonly used 52S pack refers to a battery pack composed of 52 battery cells connected in series, while a 104S pack refers to a battery pack composed of 104 battery cells connected in series. More cells connected in series usually means higher voltage output, and the weight of the battery pack will also increase accordingly. Generally speaking, a 52S pack weighs around 350KG, while a 104S pack weighs over 650KG.

[0004] In the installation and deployment of battery energy storage equipment, it is often necessary to move and install the battery packs into a specially designed energy storage cabinet. This operation is generally referred to as clustering in the industry. Because these battery packs are very heavy, equipment is usually required to assist with clustering. In existing technology, a forklift is typically used to lift the battery pack, manually align it, and then push it into the energy storage cabinet. However, due to the low lifting precision of forklifts, there are height errors after lifting, resulting in poor alignment. Multiple lifting and adjustment operations are usually required to barely achieve proper alignment with the clustering position in the energy storage cabinet, which is inefficient and very inconvenient.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides a battery pack clustering device, which can be used to perform clustering operations on battery pack 1, thereby improving the efficiency of battery pack 1 clustering and making the operation more convenient.

[0030] like Figure 1 , Figure 2 The diagram shown is a structural schematic of the battery pack clustering device. Specifically, the battery pack clustering device includes a lifting mechanism 2 and a clustering fixture 3, wherein:

[0031] The lifting mechanism 2 is provided with a lifting platform 21 that can move up and down. The lifting platform 21 is provided with screw connection holes. The clustering fixture 3 is fixedly installed on the lifting platform 21 by screw fastening, so that the clustering fixture 3 can move up and down under the drive of the lifting mechanism 2. Of course, the fastening connection between the lifting platform 21 and the clustering fixture 3 can also be achieved by other fastening methods, which are not limited here.

[0032] The cluster insertion fixture 3 includes a base plate 31 and a conveying mechanism 32 and a first height adjustment mechanism 33 disposed on the base plate 31. The conveying mechanism 32 can be a conveying device such as a chain or belt, which can be used to convey the battery pack 1 laterally and move the battery pack 1 into the energy storage cabinet. The first height adjustment mechanism 33 is disposed at the bottom of the conveying mechanism 32 and can be used to control the up and down movement of the conveying mechanism 32, thereby adjusting the overall height of the conveying mechanism 32.

[0033] In use, firstly, the battery pack 1 is moved onto the conveying mechanism 32, and then the lifting mechanism 2 controls the clustering fixture 3 to rise, so that the battery pack 1 reaches the clustering height of the energy storage cabinet. However, since the lifting mechanism 2 inevitably has a height error, alignment recognition is required (the alignment recognition can be done by human visual observation or by intelligent systems such as visual recognition systems, which is not limited here). The height difference between the battery pack 1 and the clustering position of the energy storage cabinet is observed and judged. If the height of the battery pack 1 is found to be lower than the clustering position of the energy storage cabinet, the overall height of the conveying mechanism 32 is increased by the first height adjustment mechanism 33. If the height of the battery pack 1 is found to be higher than the clustering position of the energy storage cabinet, the overall height of the conveying mechanism 32 is decreased by the first height adjustment mechanism 33, so that the battery pack 1 matches the clustering position of the energy storage cabinet. Then, the conveying mechanism 32 moves the battery pack 1 into the cluster, realizing the clustering installation of the battery pack 1.

[0034] The battery pack clustering device with the above structure can control the up and down movement of the battery pack 1 through the lifting mechanism 2, and the height of the battery pack 1 can be finely adjusted at high altitude through the first height adjustment mechanism 33. This allows the battery pack 1 to match the clustering position of the energy storage cabinet, improving the efficiency and effect of the alignment when the battery pack 1 is placed into the cluster, and making the operation more convenient.

[0035] In some embodiments, the clustering fixture 3 further includes a second height adjustment mechanism 34; the left or right side of the conveying mechanism 32 along the conveying direction is designated as a first side, and the opposite right or left side along the conveying direction is designated as a second side, for example, in this embodiment, such as Figure 3As shown, the right side (the side closer to the person) of the conveying mechanism 32 is the first side, and the left side (the side farther from the person) of the conveying mechanism 32 is the second side; the second height adjustment mechanism 34 is disposed at the bottom of the first side of the conveying mechanism 32 and can be used to adjust the height of the first side of the conveying mechanism 32.

[0036] The battery pack clustering device with the above structure has a second height adjustment mechanism 34 at the bottom of the first side of the conveying mechanism 32, which can be used to adjust the height of the first side of the conveying mechanism 32. This can correct the angle error (i.e., inconsistent left and right height) caused by factors such as uneven ground or welding errors of the energy storage cabinet, so that the battery pack 1 can be smoothly entered into the energy storage cabinet. This can improve the applicability of the battery pack clustering device and improve the clustering efficiency and effect.

[0037] In some embodiments, such as Figure 6 , Figure 7As shown, the first height adjustment mechanism 33 is a first synchronous lifting mechanism (a synchronous lifting mechanism is a mechanical device specifically designed to simultaneously and uniformly raise or lower multiple points). The first synchronous lifting mechanism includes a first lifting drive component 331 and at least two first lifting pads 332. The first lifting drive component 331 can be used to drive and control the up-and-down movement of the first lifting pads 332. At least one first lifting pad 332 is fixedly connected to the bottom of the second side of the conveying mechanism 32 (e.g., by screws, clamps, etc.), and at least one other first lifting pad 332 is not fixedly disposed at the bottom of the first side of the conveying mechanism 32. "Not fixedly disposed" means that the first lifting pad 332 located at the bottom of the first side of the conveying mechanism 32 is not fixedly connected to the conveying mechanism 32 by a fastening component. When there is no support from the second height adjustment mechanism 34, the entire conveying mechanism 32 is supported by the first height adjustment mechanism 33. The first lifting pad 332 on one side contacts and supports the bottom of the conveying mechanism 32. When the height of the first side of the conveying mechanism 32 needs to be adjusted by the second height adjustment mechanism 34, the second height adjustment mechanism 34 contacts and supports the bottom of the first side of the conveying mechanism 32. The height of the first lifting pad 332 on the first side is lower than the height of the bottom of the first side of the conveying mechanism 32, and the first lifting pad 332 on the first side does not contact the bottom of the first side of the conveying mechanism 32. At the same time, the height of the first lifting pad 332 at the bottom of the first side of the conveying mechanism 32 is lower than the height of the first lifting pad 332 at the bottom of the second side of the conveying mechanism 32. Preferably, in this embodiment, there are four first lifting pads 332, which are distributed in a square shape. Two of them are located at the bottom of the first side of the conveying mechanism 32, and the other two are located at the bottom of the second side of the conveying mechanism 32, so that the lifting effect is better.

[0038] The battery pack clustering device with the above structure has a lower height for the first lifting pad 332 located at the bottom of the first side of the conveying mechanism 32 than for the first lifting pad 332 located at the bottom of the second side of the conveying mechanism 32. This results in the conveying mechanism 32 being in a left-high-right-low state when the second height adjustment mechanism 34 is not involved, making it suitable for ground conditions where the left side is low and the right side is high. Furthermore, by adjusting the second height adjustment mechanism 34, the conveying mechanism 32 can be made to be in a horizontal state or a left-low-right-high state, making it suitable for horizontal or left-high-right-low ground conditions, thus increasing the applicability of the battery pack clustering device.

[0039] In some embodiments, the second height adjustment mechanism 34 is a second synchronous lifting mechanism, which includes a second lifting drive component 341 and at least one second lifting pad 342 (in this embodiment, there are two second lifting pads 342). The second lifting drive component 341 can be used to drive and control the up-and-down movement of the second lifting pads 342. The second lifting pads 342 are not fixedly disposed at the bottom of the first side of the conveying mechanism 32. The term "not fixedly disposed" means that the second lifting pads 342 and the conveying mechanism 32 are not fixed together by a fastening component. When the second height adjustment mechanism 34 is not needed to adjust the height of the first side of the conveying mechanism 32, the entire conveying mechanism 32 is supported by the first height adjustment mechanism 33. At this time, the second lifting pad 342 does not contact the bottom of the conveying mechanism 32. When the second height adjustment mechanism 34 is needed to adjust the height of the first side of the conveying mechanism 32, the second lifting drive assembly 341 drives and controls the second lifting pad 342 to rise. At this time, the second lifting pad 342 contacts the bottom of the first side of the conveying mechanism 32 and supports the first side of the conveying mechanism 32.

[0040] The battery pack clustering device with the above structure sets the second height adjustment mechanism 34 as a second synchronous lifting mechanism composed of a second lifting drive component 341 and at least one second lifting pad 342, which makes the lifting more stable and the height adjustment effect better.

[0041] In some embodiments, the first height adjustment mechanism 33 is further provided with a first adjustment handle 333 for controlling and adjusting the overall height of the conveying mechanism 32. For example, in this embodiment, the height of the first lifting pad 332 is adjusted by controlling the first adjustment handle 333. The second height adjustment mechanism 34 is further provided with a second adjustment handle 343 for controlling and adjusting the height of the first side of the conveying mechanism 32. For example, in this embodiment, the height of the second lifting pad 342 is adjusted by controlling the second adjustment handle 343.

[0042] The battery pack clustering device with the above structure, through the setting of the first adjustment handle 333 and the second adjustment handle 343, can facilitate on-site control by maintenance personnel, making operation simpler and more convenient.

[0043] In some embodiments, the lifting mechanism 2 is a movable scissor lift trolley; a scissor lift trolley is a mechanical device specifically designed to safely lift personnel and / or materials to heights for work. It can raise and lower the lifting platform 21 by extending and retracting a pair of cross-shaped (scissor-like) support arms in the vertical direction; at the same time, the scissor lift trolley is equipped with wheels and can move on the ground.

[0044] The battery pack installation equipment with the above structure, with the lifting mechanism 2 set as a movable scissor-type aerial work trolley, not only has good stability and strong load-bearing capacity, but also is flexible in movement and highly safe, making it a better choice. In the customer's energy storage power station site, the battery pack 1 disassembly and assembly needs for on-site maintenance can be flexibly met.

[0045] In some embodiments, such as Figure 3 , Figure 4 , Figure 5 As shown, the conveying mechanism 32 is a roller conveyor belt, and a first pedestrian walkway 4 is provided on the side of the roller conveyor belt, which can be used for maintenance personnel to stand or walk.

[0046] The battery pack loading device with the above structure can significantly reduce friction in the absence of power, as the installation site is often without electricity. This allows maintenance personnel to move the battery pack 1 more easily. Furthermore, the roller conveyor belt offers good compatibility for placing and moving the battery pack 1, and is more suitable for various battery pack sizes. A first pedestrian walkway 4 is provided on the side of the roller conveyor belt, allowing maintenance personnel to stand or walk directly on it for positioning and moving the battery pack 1 without the need for a separate ladder, thus improving operational convenience and safety.

[0047] In some embodiments, the roller conveyor belt includes two sets of independently operating roller assemblies located on the left and right sides, and a second pedestrian passage 5 is provided between the two sets of roller assemblies.

[0048] The battery pack loading equipment with the above structure has a second pedestrian walkway 5 set in the middle of the roller conveyor belt. Maintenance personnel can stand on the second pedestrian walkway 5 and push the battery pack 1 more forcefully.

[0049] In some embodiments, limit baffles 321 are provided on the left and right sides of the roller conveyor belt to prevent the battery pack 1 from falling off the left and right sides of the roller conveyor belt, thereby improving the safety of the battery pack loading device.

[0050] In some embodiments, the clustering fixture 3 is surrounded by safety railings 6, and safety belt loops 7 are provided on the safety railings 6 to prevent maintenance personnel from falling from heights, thereby further improving the safety of the battery pack clustering equipment.

[0051] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. All equivalent changes made in accordance with the shape, structure and principle of the present utility model should be covered within the protection scope of the present utility model.
