Detailed implementation manners

[0029] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings. However, the implementation manners of the present utility model are not limited thereto.

[0030] As Figures 1 - 4 shown, the energy storage integrated cabinet provided in this embodiment includes: a cabinet body 1, and a battery rack assembly 2 is arranged inside the cabinet body 1. The battery rack assembly 2 is a frame structure.

[0031] The battery rack assembly 2 includes a plurality of support assemblies 21. A battery box 3 is provided on each support assembly 21. The battery box 3 is used to accommodate and protect energy storage batteries (not shown in the drawings). In order to ensure the stability of the battery box 3 on the support assembly 21, a positioning assembly 4 is provided between the support assembly 21 and the battery box 3.

[0032] The positioning assembly 4 includes a first member 41 and a second member 42.

[0033] One of the members is arranged at the rear end of the support assembly 21, and the other member is arranged at the rear end of the battery box 3. These two members are designed to be able to penetrate each other.

[0034] Through the mutual penetration of the first member 41 and the second member 42, the positioning assembly 4 can effectively fix the position of the rear end of the battery box 3 in the vertical direction. This fixing method can prevent the rear end of the battery box 3 from displacing in the vertical direction. At the same time, this design also facilitates the installation and disassembly of the battery box 3, which is beneficial to later maintenance and replacement work.

[0035] In one embodiment, the support assembly 21 includes two opposing support members 211. This design can support the left and right corners of the bottom of the battery box 3, respectively, providing more stable support for the battery box 3. The two support members 211 can be made of the same material and structure to ensure balanced support force.

[0036] A first component 41 is provided at the rear end of the support member 211 , and a second component 42 is provided at the rear end of the battery box 3 . The second component 42 is inserted into the first component 41 .

[0037] Specifically, the support member 211 and the battery box 3 both have opposing front and rear ends. The front end of the battery box 3 refers to the end of the battery box 3 closest to the operator after the operator places the battery box 3 on the support member 211. The rear end is the end opposite the front end. The same applies to the support member 211.

[0038] The rear end of each support member 211 is provided with a first member 41. The position and number of the second members 42 correspond one-to-one with the first members 41. After the battery box 3 is placed on the support assembly 21, the second members 42 can be accurately inserted into the corresponding first members 41.

[0039] The second member 42 is a structure that matches the first member 41 . For example, if the first member 41 is a protrusion, the second member 42 may be a corresponding groove.

[0040] In this embodiment, during installation, the second member 42 at the rear end of the battery compartment 3 and the first member 41 at the rear end of the support member 211 intersect with each other. This interlaced design vertically secures the rear end of the battery compartment 3. In this way, the rear end of the battery compartment 3 is firmly fixed to the support assembly 21 in the vertical direction, effectively preventing vertical displacement of the battery compartment 3 due to vibration or external forces.

[0041] This design also has the advantage of being easy to install and disassemble. When the battery box 3 needs to be replaced or maintained, the battery box 3 can be easily taken out by simply pulling the second component 42 out of the first component 41, which greatly improves the convenience of operation.

[0042] In one embodiment, the first member 41 is vertically arranged, and its top end extends toward the battery box to form a positioning portion 411. The positioning portion 411 cooperates with the second member 42 to achieve a positioning and fixing function.

[0043] The second component 42 is provided with a through hole 421 that matches the positioning portion 411 . Matching here means that the position, size and shape of the through hole 421 must match the positioning portion 411 of the first component 41 .

[0044] During the installation of the battery box 3, the positioning portion 411 of the first member 41 will penetrate into the through hole 421 of the second member 42. The through hole 421 can limit the positioning portion 411 in the vertical direction, thereby preventing the positioning portion 411 from displacing in the vertical direction. This insertion design can not only fix the position of the rear end of the battery box 3 in the vertical direction.

[0045] In this embodiment, the extension of the top end of the first member 41 towards the battery box means that the top end is bent forward, and the bent portion forms the positioning portion 411. The bending angle of the positioning portion 411 can be designed according to actual needs, usually about 90 degrees, so as to be aligned with the through hole 421 of the second member 42.

[0046] In this embodiment, the through hole 421 can be circular, square or other suitable shapes, but it needs to cooperate with the positioning portion 411 to avoid large-amplitude up and down shaking.

[0047] In this embodiment, as Figure 4 shown, both the first member 41 and the second member 42 are plate-like structures.

[0048] In one embodiment, the battery rack assembly 2 includes a plurality of first cavities 201 and second cavities 202 adjacent to each other on the left and right. A support assembly 21 is provided in each first cavity 201. A battery box 3 is provided on one support assembly 21. This design enables each battery box 3 to have its own independent installation space, facilitating management and maintenance.

[0049] These battery boxes 3 can be arranged in a variety of ways within the battery rack assembly 2, such as vertical stacking, horizontal juxtaposition or combined arrangement. Each battery box 3 is fixed to the corresponding support assembly 21 through the aforementioned positioning assembly 4 to ensure overall stability.

[0050] The second cavity 202 is used to install the energy storage converter cabinet 5. Installing the energy storage converter cabinet 5 in an independent cavity separates the energy storage converter cabinet 5 from the battery box 3, facilitating the installation and maintenance of the energy storage integrated cabinet.

[0051] The size of the second cavity 202 should be determined according to the size of the selected energy storage converter cabinet 5 to ensure there is enough space to install the converter (PCS) and its related accessories in the energy storage converter cabinet 5, such as UPS, wire wound resistors, transformers, etc. (not shown in the drawings).

[0052] In one embodiment, the battery rack assembly 2 further includes a third cavity 203 provided at the bottom of the plurality of first cavities 201.

[0053] Inside the third cavity 203, a distribution box 8 and a high-voltage box 9 are installed. The distribution box 8 is used to distribute electric energy and plays roles such as providing power-off protection in case of overload, short circuit, and leakage in the circuit. The high-voltage box 9 collects the voltage and current data of the energy storage battery and communicates with the battery management system (not shown in the attached drawings) and the PCS.

[0054] In one embodiment, a partition 6 is provided between the plurality of first cavities 201 and the third cavity 203. Since the distribution box 8 and the high-voltage box 9 generate heat during operation, the setting of the partition 6 can effectively block the direct upward transfer of this heat and protect the upper battery box 3 from overheating.

[0055] The setting of the partition 6 enables the upper and lower two regions (the first cavity and the third cavity) to be independently maintained and repaired without affecting each other. For example, when repairing the distribution box 8 at the bottom, it will not interfere with the upper battery box 3.

[0056] In one embodiment, inclined support columns are respectively provided on the left and right sides of the battery rack assembly 2. In this embodiment, the support columns include a first column 71 and a second column 72.

[0057] The first column 71 is inclined and arranged on the left side of the battery rack assembly 2. Its top end is connected to the top end of the battery rack assembly 2, and its bottom end is connected to the partition 6.

[0058] By connecting the bottom end of the first column 71 to the partition 6, a stable triangular structure is formed, enhancing the structural stability of the battery rack assembly 2. In addition, the first column 71 does not directly extend to the bottom end of the battery rack assembly 2, reserving more space for the third cavity 203, which is convenient for the installation of the distribution box 8 and the high-voltage box 9 and the cable layout.

[0059] The second column 72 is inclined and arranged on the right side of the battery rack assembly 2. Different from the first column 71, its top end is connected to the top end of the battery rack assembly 2, and its bottom end is connected to the bottom end of the battery rack assembly 2, forming a triangular structure. This design enables the second column 72 to provide full-height support for the entire battery rack assembly 2.

[0060] The cross-sectional shapes of the two columns can be square, rectangular, or other suitable shapes to provide the best support effect.

[0061] The above is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
