[0002] As global energy demand grows, people's demand for energy storage and clean energy is also increasing. As a new type of energy storage equipment, station-type energy storage power stations can not only meet the demand for energy storage, but also provide more stable and reliable support for clean energy. Among them, station-type energy storage is to place its equipment battery packs on battery racks and distribute them in the station, so that it is less affected by the environment, and the maintenance and replacement of equipment is also more convenient, which plays an important role in ensuring the stability and reliability of the power grid.

[0003] However, traditional battery racks have at least the following problems during their application: on the one hand, the battery packs need to be transported to the station building after production, and a carrier is required during the transportation process. If traditional battery racks are used as carriers to place the battery packs for transportation, due to transportation costs and operational limitations, the height of the battery racks cannot be too high, resulting in failure to meet the transportation needs of the battery packs. On the other hand, after the battery packs are transported to the station building, since the traditional battery racks in the station building are relatively high, it is difficult to use a forklift to place the battery packs into the battery racks, and the construction period is long, the cost is high and it is not safe. At the same time, when repairing and replacing battery packs in high places, it is difficult to take out the battery packs for repair.

[0004] Therefore, there is an urgent need to provide a station building energy storage building block battery rack to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined with each other and quoted from each other without contradiction.

[0024] The present application embodiment provides a station building energy storage building block battery rack, please refer to Figure 1 , Figure 2 As shown, at least one battery rack monomer 1 is provided with a receiving cavity 11 for accommodating a battery pack 2, a battery box slide 12 is provided in the receiving cavity 11, and the battery pack 2 is placed on the battery box slide 12; wherein two battery rack monomers 1 adjacent to each other in a first direction are stacked in sequence, and two battery rack monomers 1 adjacent to each other in a second direction are detachably connected. In this embodiment, the first direction can be set to a vertical direction y, and the second direction can be set to a horizontal direction x.

[0025] In this embodiment, the battery pack 2 can be loaded into the accommodating cavity 11 of the battery rack monomer 1 before the manufacturer ships the battery pack 2, so that the battery rack monomer 1 and the battery pack 2 can be integrated and transported to the station building together. In the station building, the battery rack monomer 1 can be integrated into the building block battery rack in the manner of building blocks. The building block battery rack can adjust the height and number of layers according to the height of the station building, thereby achieving the purpose of flexible disassembly and assembly. At the same time, the structure of the building block battery rack is also more convenient for repairing and replacing the battery pack 2. The battery pack 2 on the lower layer can be directly taken out, and the battery pack 2 on the higher layer can be removed together with the battery rack monomer 1 by a forklift. Therefore, the battery pack 2 can be loaded into the battery rack monomer 1 and transported together, which can save transportation tooling and reduce transportation costs. It is also more convenient to install the battery rack monomer 1 with a forklift in the station building, which can reduce costs and shorten construction period.

[0026] Please refer to Figure 1 As shown, in the present embodiment, it should be noted that the battery rack monomer 1 includes a bottom frame 13, a top frame 14 and an intermediate frame 15 connected between the bottom frame 13 and the top frame 14. The top frame 14 is parallel to and opposite to the bottom frame 13. The intermediate frame 15 includes two groups of side connection frames 151 composed of a plurality of connection columns. The two groups of side connection frames 151 are oppositely arranged in a horizontal direction. The upper part of the side connection frame 151 is connected to the top frame 14, and the lower part of the side connection frame 151 is connected to the bottom frame 13. Then, a accommodating cavity 11 for accommodating the battery pack 2 is formed between the bottom frame 13, the top frame 14 and the intermediate frame 15.

[0027] In some embodiments, the battery box slides 12 are symmetrically arranged on both sides of the interior of the middle frame 15. In other words, the battery box slides 12 are arranged on the side connection frame 151, and several layers of battery box slides 12 are equidistantly distributed along the height direction of the side connection frame 151, and the battery packs 2 are horizontally placed on each layer of battery box slides 12. The battery box slide 12 includes a first side connection plate 121 fixedly connected to the side connection frame 151 and a first bottom connection plate 122 connected to the first side connection plate 121. The first bottom connection plate 122 is arranged at 90 degrees to the first side connection plate 121, that is, the battery box slide 12 is arranged in an L shape. The first side connecting plate 121 is used for the side of the battery pack 2 to abut against, and the first bottom connecting plate 122 is used to support the bottom of the battery pack 2. Therefore, when the battery pack 2 is placed in the middle frame 15, the bottom of the battery pack 2 can be slidably installed on the first bottom connecting plate 122 of the battery box slide 12, and the battery box slide 12 is limited by the first side connecting plate 121, so that the battery pack 2 can only slide along the length direction of the first bottom connecting plate 122, thereby ensuring the installation stability of the battery pack 2 in the accommodating cavity 11. Preferably, a battery box stopper 3 is also connected to the end of the battery box slide 12, and the battery box stopper 3 can block the battery pack 2, thereby preventing the battery pack 2 from sliding out of the end of the battery box slide 12 when sliding.

[0028] In this embodiment, by setting up a multi-layer battery box slide 12 in the middle frame 15, multiple battery packs 2 can be slidably installed on the battery box slide 12 at the same time, so that one battery rack unit 1 can hold multiple battery packs 2, and the number of battery packs 2 to be placed can be selected according to actual needs.

[0029] Please continue to refer to Figure 1 As shown, in the present embodiment, it is also necessary to explain that a distance L is left between the bottom frame 13 and the horizontal plane supported by the bottom end of the middle frame 15. Preferably, a distance L of at least 100 mm is left between the bottom frame 13 and the horizontal plane supported by the bottom end of the middle frame 15. By using this distance L, it is convenient to directly insert the fork of the forklift from the space at the bottom during the process of forklift transporting the battery rack single cell 1, so as to realize the installation and transportation of the battery rack single cell 1.

[0030] Please continue to refer to Figure 1 As shown, in this embodiment, it should also be noted that battery rack slides 16 are symmetrically arranged on both sides of the top of the top frame 14, and the bottom end of the battery rack single cell 1 slides in the battery rack slide 16 and is stacked with the adjacent battery rack single cell 1, thereby realizing the stacking and installation of multiple battery rack single cells 1.

[0031] In some embodiments, the battery rack slide 16 includes a second side connecting plate 161 and a second bottom connecting plate 162, the second bottom connecting plate 162 is fixed to the top of the top frame 14, the bottom of the second side connecting plate 161 is fixedly connected to the second bottom connecting plate 162, and the second side connecting plate 161 and the second bottom connecting plate 162 are arranged at 90 degrees, that is, the battery rack slide 16 is arranged in an L shape. The second side connecting plate 161 of the battery rack slide 16 is used for the side of the battery rack monomer 1 to abut against, and the second bottom connecting plate 162 of the battery box slide 12 is used to support the bottom of the battery rack monomer 1. Therefore, when the battery rack monomer 1 is stacked, the bottom of the battery rack monomer 1 can be slidably installed on the second bottom connecting plate 162 of the lower battery rack slide 16, and is limited by the second side connecting plate 161 of the battery rack slide 16, so that the battery rack monomer 1 can only slide along the length direction of the second bottom connecting plate 162, thereby ensuring that the battery rack monomer 1 will not shake in the left and right directions, and ensuring installation stability. Preferably, a battery rack baffle 4 is also provided at the end of the battery rack slide 16. When the battery rack monomer 1 slides along the battery rack slide 16 and abuts against the battery rack baffle 4, the battery rack baffle 4 can prevent the battery rack monomer 1 from falling and limit the stacked battery rack monomers 1.

[0032] Please refer to Figure 2 , Figure 3 As shown, in this embodiment, it is also necessary to explain that a front end connector 5 is provided at the front end of the battery rack monomer 1, and a rear end connector 6 is provided at the rear end of the battery rack monomer 1; the front end connector 5 is used to detachably connect adjacent battery rack monomers 1 in the horizontal direction x and the vertical direction y, and the rear end connector 6 is used to detachably connect adjacent battery rack monomers 1 in the horizontal direction.

[0033] In some embodiments, the front end connector 5 and the rear end connector 6 are both configured in a plate shape, and the four ends of the front end connector 5 are respectively connected to the ends of four battery rack monomers 1 by means of bolts or the like. In other words, the upper and lower ends on the left side of the front end connector 5 are respectively connected to the ends of two battery rack monomers 1 in the vertical direction y, and the upper and lower ends on the right side of the front end connector 5 are respectively connected to the ends of two battery rack monomers 1 in the vertical direction y on another adjacent building block battery rack. The left and right ends of the rear end connector 6 are respectively connected to two adjacent battery rack monomers 1 in the horizontal direction x by means of bolts or the like.

[0034] It should be noted that in the above embodiments, the structures of the front end connector 5 and the rear end connector 6 can be implemented by other structures besides the structures described in the embodiments, which are not listed one by one in this application.

[0035] Please refer to Figure 2As shown, in this embodiment, it should also be noted that the battery rack monomer 1 at the bottom layer is fixed to the channel steel 7 on the bottom surface of the station building, and the four ends of the battery rack monomer 1 are fixedly connected to the channel steel 7 through fixed angle pieces 8.

[0036] In some embodiments, the channel steel 7 can be divided into four types according to the shape, namely, cold-bent equilateral channel steel, cold-bent unequal-sided channel steel, cold-bent inner-curled channel steel, and cold-bent outer-curled channel steel hot-rolled. Hot rolling is relative to cold rolling. Cold rolling is rolling performed below the recrystallization temperature, while hot rolling is rolling performed above the recrystallization temperature. The strength of hot-rolled channel steel is higher than that of ordinary steel, and it can withstand greater loads. In addition, hot-rolled channel steel has strong plasticity, can withstand large distortion and torsion and other deformations, is light in weight, and has a long service life. Specifically, the bottom channel steel 7 here can be made of 16# hot-rolled channel steel. The channel steel 7 is pre-buried in the floor of the station building, and the two ends of the channel steel 7 are respectively connected to the building load-bearing beams, thereby further strengthening the connection and fixing strength of the channel steel 7, so as to facilitate the load-bearing building block battery rack connected to the channel steel 7.

[0037] In some embodiments, the fixed angle piece 8 is made of stainless steel and is set at a right angle. One side of the fixed angle piece 8 is in contact with the side wall of the battery rack monomer 1 at the bottom layer and is fastened by bolts, and the other side is in contact with the side wall of the channel steel 7 and is fixed by bolts, thereby tightly fixing the battery rack monomer 1 on the channel steel 7, thereby fixing the building block battery rack on the channel steel 7, and installing the battery pack 2 in the station building. The height and number of layers of the building block battery rack can be adjusted as needed, and installation and maintenance are very convenient.

[0038] The implementation principle of this embodiment is as follows: before shipment from the manufacturer, the battery pack 2 can be loaded into the accommodating cavity 11 of the battery rack monomer 1. After the battery rack monomer 1 and the battery pack 2 are integrated, they can be transported and shipped to the station together. The battery pack 2 is loaded into the battery rack monomer 1 and transported together, which can save transportation tooling and reduce transportation costs. It is also convenient to install the battery rack monomer 1 in the station with a forklift. The battery rack monomer 1 is integrated into a building block battery rack in a building block manner. The height and number of layers of the building block battery rack can be adjusted according to the height of the station to achieve the purpose of flexible disassembly and assembly. At the same time, the building block battery rack is more convenient for repairing and replacing the battery pack 2. The battery pack 2 can be directly taken out at the lower level, and the battery pack 2 at the higher level can be removed together with the battery rack monomer 1 by a forklift, thereby achieving the purpose of reducing costs and improving work efficiency.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present application should be included in the protection scope of the present application.
