Description

Technical Field

[0001] This utility model mainly relates to the field of energy storage equipment technology, specifically to a modular battery pack fixed support structure for energy storage power stations. Background Technology

[0002] With the rapid development of new energy sources, energy storage battery technology has developed rapidly, and key technical indicators such as battery safety, cycle life and energy density have been greatly improved. Energy storage power stations specifically refer to large-scale energy storage facilities facing the power grid, with a capacity ranging from several megawatts to hundreds of megawatts, reaching the scale of power stations to a certain extent.

[0003] In existing energy storage power stations, modular battery packs mostly adopt an integrated fixed structure. This integrated fixed structure requires hoisting as a whole during installation, which is cumbersome. Furthermore, if a single battery pack module fails, the entire structure must be disassembled for maintenance, resulting in low maintenance efficiency. In addition, the fixed support structure is directly connected to the battery pack module and lacks heat dissipation design. The heat generated by the battery pack during operation is difficult to dissipate quickly, which can easily lead to excessively high battery temperatures.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0030] See attached document Figure 1-6 A modular battery pack fixing support structure for an energy storage power station includes multiple transverse beams 1, longitudinal beams 2, support columns 3, and side limiting plates 4. The transverse beams 1, longitudinal beams 2, and support columns 3 are interlocked and fixed with bolts. The side limiting plates 4 are fixed with the support columns 3 by bolts. After the transverse beams 1, longitudinal beams 2, and support columns 3 are assembled, they form an installation cavity for accommodating battery pack modules. The installation cavity is divided into multiple installation cavities from top to bottom by multiple side limiting plates 4.

[0031] The longitudinal beam 2 is the longitudinal main frame. The limiting slots 201 on both sides of the beam are perfectly matched with the cross-sectional shape of the transverse beam 1. The transverse beam 1 can be directly embedded into the limiting slots 201 to avoid offset or coaxiality error during assembly, which greatly improves the efficiency of frame assembly. The adjustment waist holes 202, which are distributed at intervals with the limiting slots 201, allow the transverse beam 1 to be finely adjusted along the length of the longitudinal beam 2, thereby adapting to battery modules of different lengths and improving the compatibility of the structure with multiple battery models. The waist holes provide adjustment margin in the length direction for bolt connections. Even if there are slight dimensional deviations on site, the holes can be aligned to reduce assembly difficulty.

[0032] The first bolt hole 203 inside the limiting slot 201 is used for rigid locking of the longitudinal beam 2 and the transverse beam 1 after they are inserted. When the transverse beam 1 is inserted into the limiting slot 201, the bolt passes through the first bolt hole 203 and the corresponding hole of the transverse beam 1, so that the two can be firmly connected, ensuring the stability of the longitudinal and transverse structures and avoiding relative displacement under vibration or load.

[0033] The base plate 101 of the transverse beam 1 is fixed to the installation ground or the support surface inside the container to ensure the flatness and stability of the module when it is placed, and to avoid damage to the battery casing caused by partial suspension. The shape of its mounting slot 102 is precisely matched with the insertion part 301 of the support column 3 to realize the vertical insertion connection between the transverse beam 1 and the support column 3. When the insertion part 301 of the support column 3 is inserted into the mounting slot 102, the two first form a temporary positioning relationship without bolts, and then are tightened with bolts, simplifying the assembly and docking process.

[0034] When the transverse beam 1 is connected to the support column 3, the second bolt hole 103 corresponds to the fourth bolt hole 303 of the insertion part 301 of the support column 3. After the bolt passes through both, the transverse beam 1 and the support column 3 are vertically locked, which strengthens the vertical support strength of the frame. When connected to the side limiting plate 4, the third bolt hole 104 corresponds to the adjustment waist hole 406 of the side limiting plate 4. The bolt and the waist hole realize the transverse limiting connection between the transverse beam 1 and the side limiting plate 4.

[0035] In the support column 3, the fourth bolt hole 303 on the side of its insertion part 301 precisely corresponds to the third bolt hole 104 on the side wall of the slot 102 of the transverse beam 1. After the bolt passes through both, the support column 3 and the transverse beam 1 are firmly locked, further strengthening the vertical load-bearing capacity of the frame and ensuring that the structure will not loosen even in the vibration environment of the energy storage power station during transportation or operation. The side limiting plate 4 cooperates with the fifth bolt hole 404 of the positioning surface 401 and the second adjustment waist hole 304, and can be freely adjusted in the height direction of the support column 3. It can not only adapt to battery modules of different heights, but also flexibly adjust the interlayer distance according to heat dissipation requirements or operation and maintenance requirements.

[0036] The side limiting plate 4 adopts a bent plate structure. Through the spatial layout of the positioning surface 401, the first mounting surface 402, and the second mounting surface 403, it simultaneously achieves connection with the support column 3 and limits the two sides of the battery pack module. The fifth bolt hole 404 on the positioning surface 401 cooperates with the adjustment waist hole 304 of the support part 302 of the support column 3. After the bolt passes through both, the side limiting plate 4 is vertically fixed to the support column 3, becoming a vertical partition that separates the installation cavities. This divides the originally continuous installation cavity into multiple independent installation cavities, preventing the battery pack modules from being stacked and squeezed in the vertical direction. The first mounting surface 402 and the second mounting surface 403... Mounting surfaces 403 are perpendicular to each other and correspond to two adjacent sidewalls of the battery module. They can be connected to the first mounting surface 402 or the second mounting surface 403 according to actual installation requirements, restricting the displacement of the battery module in the horizontal or vertical direction. The adjustment waist holes 3 405 and 406 on them allow the side limiting plate 4 to be finely adjusted along the extension direction of the transverse beam 1 or the longitudinal beam 2, accurately fitting battery modules of different specifications, improving the compatibility of the structure with modules of multiple specifications. The elongated structure of the waist holes facilitates hole alignment during on-site installation, eliminating the need for strict hole calibration and greatly improving assembly efficiency.

[0037] In summary, this structure, through the insertion and bolting of the transverse beam 1, longitudinal beam 2, and supporting column 3, forms an installation cavity that provides basic housing space for the battery pack modules. The intervention of the side limiting plate 4 further divides it into multiple independent installation cavities. This layered limiting structure prevents vertical stacking and compression of the battery pack modules, reduces the load on the bottom module, and extends battery life. The spaces reserved between layers form heat dissipation channels, accelerating heat dissipation and reducing the risk of thermal runaway. The layered structure also facilitates the inspection and replacement of individual battery pack modules, significantly shortening maintenance time.

[0038] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
