[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] With the increasing integration and scale of energy storage facilities, the weight of individual energy storage units is rising, and the requirements for load-bearing capacity are also increasing. Indoor-installed energy storage facilities have not yet shown significant pressure, but outdoor-use facilities, especially deeply buried battery compartments, are greatly affected by geological conditions such as land subsidence during installation and use. Whether it is the suspension of the bottom area of ​​the facility or the tilting of the facility, it will seriously affect the operational safety of the facility. Therefore, designing a foundation structure that can achieve stable load-bearing capacity has significant application value.

[0031] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of the overall structure of the battery compartment base 10 provided in this embodiment of the utility model.

[0032] To solve the above-mentioned technical problems, this application discloses a battery compartment base 10, which includes a base plate 11 and a plurality of side plates 12: the side plates 12 are disposed on one side of the base plate 11, and the base plate 11 and the plurality of side plates 12 together form an electrical space 13, which is used to place electrical equipment, and the edges of the side plates 12 and the base plate 11 are spaced apart.

[0033] For clarity, one application method of this embodiment is described here, and should not be construed as limiting the scope of protection of this utility model. First, a pit large enough to accommodate the battery compartment base 10 is excavated in the site selected for placement. The depth of the pit can be greater than or less than the height of the battery compartment base 10, preferably greater than half the height of the battery compartment base 10. Then, the bottom of the pit is leveled and compacted, and the battery compartment base 10 is placed in it, so that the surface of the substrate 11 away from the electrical space 13 is in stable contact with the ground. Then, some soil is backfilled and compacted, so that the side of the side plate 12 away from the electrical space 13 and the edge of the substrate 11 protruding from the side plate 12 are covered with soil. Finally, an energy storage device such as a battery module 20 is placed in the electrical space 13, and the energy storage device is fixed to the substrate 11 or the side plate 12. It is conceivable that prefilling the bottom of the pit with gravel or other base materials and replacing the backfill with concrete can enhance the stability of the structure. These are improvements that the technical personnel in charge of construction can easily make without any creative effort, so they will not be elaborated here.

[0034] In this embodiment, the substrate 11 provides a stable base for the placement of electrical equipment. Because the bottom of the electrical space 13 is supported by the entire substrate 11, even if local land subsides below the battery compartment base 10, the equipment within the electrical space 13 will remain on a stable plane before the substrate 11 is damaged. The positional relationship between the equipment and each fixing point of the substrate 11 remains relatively static, preventing the equipment from cracking due to geological changes. Furthermore, the upper and lower edges of the portion of the substrate 11 protruding from the side plate 12 are clamped by the surrounding soil or concrete, further reducing the risk of the entire battery compartment base 10 overturning.

[0035] Compared with the prior art, the battery compartment base 10 provided in this embodiment can be installed in poor geological conditions, and can also effectively reduce the damage caused by geological changes after installation, protecting the safe operation of the electrical equipment it supports.

[0036] In some embodiments of this application, the battery compartment base 10 further includes a plurality of foundation piles 14, which are disposed on the side of the substrate 11 away from the electrical space 13, and each foundation pile 14 is perpendicular to the substrate 11.

[0037] The foundation piles 14 installed at the bottom of the battery compartment base 10 are vertically inserted into the ground when the battery compartment base 10 is hoisted into place. When there is a risk of tilting of the battery compartment base 10, the foundation piles 14 interfere and rub against the ground, thus curbing the tilting tendency of the battery compartment base 10. Based on the lever principle, provided that the structural strength of the foundation piles 14 is sufficient, increasing the length of the foundation piles 14 will further enhance the ability to prevent tilting.

[0038] Furthermore, the end of the foundation pile 14 furthest from the base plate 11 is tapered, so that when the foundation pile 14 is inserted into the ground, the soil occupying the space of the foundation pile 14 will be pushed out in all directions. This facilitates the insertion of the foundation pile 14 and also increases the pressure of the soil on the foundation pile 14, thereby enhancing the friction between the foundation pile 14 and the soil.

[0039] Please refer to the following: Figure 2 As shown, Figure 2 It is along Figure 1 A cross-sectional view of line AA in the middle.

[0040] In some embodiments of this application, the battery compartment base 10 further includes multi-layer ring beams 15, which are embedded in the substrate 11, with adjacent ring beams 15 spaced apart, and the outermost ring beam 15 is attached to the side plate 12.

[0041] The ring beam 15 enhances the structural strength of the substrate 11. When the device is supported by the area corresponding to the ring beam 15, it is not only the substrate 11 in the projection area of ​​the device that supports it, but the ring beam 15 also transmits and disperses the pressure of the device, so that the substrate 11 supports the device over a larger area, reducing the pressure concentration in a small area.

[0042] Optionally, the battery compartment base 10 also includes multiple longitudinal beams 17, which are embedded in the substrate 11 and extend radially from the geometric center of the substrate 11. The projections of the side plate 12 and the longitudinal beams 17 on the substrate 11 have overlapping areas.

[0043] Similarly, the longitudinal beam 17 distributes the pressure of the side plate 12 on the base plate 11 to both sides of the side plate 12, increasing the pressure-bearing area, reducing the pressure, and decreasing the risk of the base plate 11 collapsing under the pressure of the side plate 12. Compared with the technical solution of embedding the ring beam 15 in the base plate 11, this technical solution is more suitable for the installation method of supporting electrical equipment with the side plate 12.

[0044] Please refer to the following: Figure 3 and Figure 4 As shown, Figure 3 This is a bottom view of the battery compartment base 10 provided in another embodiment of the present invention; Figure 4 This is a cross-sectional schematic diagram of the battery compartment base 10 provided in another embodiment of the present invention.

[0045] In some embodiments of this application, the substrate 11 includes a plurality of first plates 111 and a plurality of second plates 112. The first plates 111 and the second plates 112 are alternately arranged and spliced ​​to form the substrate 11, and an included angle is formed between any of the first plates 111 and the second plates 112.

[0046] The first plate 111 and the second plate 112 form an angle, that is, the substrate 11 is not a complete plane. There are multiple inclined surfaces at the bottom of the battery compartment base 10. During the installation of the battery compartment base 10 and subsequent work, the inclined bottom surface is used to guide the flow of loose soil, so that the loose soil in a small area is induced and evenly distributed as the battery compartment base 10 sinks as a whole, so as not to form voids in a small area and cause uneven distribution of the substrate 11.

[0047] Furthermore, in the direction from the edge of the substrate 11 close to the center of the substrate 11, both the first plate 111 and the second plate 112 are inclined toward the electrical space 13.

[0048] In the direction from the edge of the substrate 11 towards the center of the substrate 11, the first plate 111 and the second plate 112 are inclined toward the electrical space 13. That is, the side of the substrate 11 away from the electrical space 13 forms a concave shape. The soil under the battery compartment base 10 is compacted to form a pointed cone embedded in the concave shape. The two work together to further position the battery compartment base 10, enhance the stability of the structure, and prevent the battery compartment base 10 from having a tendency to shift laterally to one side due to unilateral inclination.

[0049] Furthermore, a first groove 113 is formed on the side of the substrate 11 away from the electrical space 13, and the first groove 113 is disposed at the connection between any adjacent first plate 111 and second plate 112.

[0050] The concave structure formed by the first plate 111 and the second plate 112 causes soil to tend to accumulate at the angle between the first plate 111 and the second plate 112. The design of the first groove 113 is, on the one hand, to guide the soil, directing the accumulated soil toward the center of the substrate 11 to achieve a compaction and positioning effect. To this end, an optimized implementation is to increase the inclination of the bottom of the first groove 113 and increase the depth of the first groove 113 as it moves away from the edge of the substrate 11, so that the soil can be guided to the center of the substrate 11 more quickly in the first groove 113. On the other hand, the relatively firm soil at the angle between the first plate 111 and the second plate 112 is embedded in the first groove 113, which also achieves a better positioning effect.

[0051] Furthermore, a second groove 114 is formed on the side of the first plate 111 away from the electrical space 13, the second groove 114 extending from the edge of the substrate 11 to the first groove 113; and / or, a third groove 115 is formed on the side of the second plate 112 away from the electrical space 13, the third groove 115 extending from the edge of the substrate 11 to the first groove 113.

[0052] The second groove 114 and the third groove 115 further facilitate the convergence of soil into the first groove 113. Furthermore, the soil embedded in the second groove 114 and the third groove 115 can act as an anchor similar to the soil in the first groove 113, enhancing the fixing effect of the battery compartment base 10.

[0053] In some embodiments of this application, the battery compartment base 10 further includes a manhole 16, which is located on the side of the side plate 12 away from the electrical space 13. The manhole 16 has a maintenance passage 161, and the side plate 12 has a maintenance opening 122. The maintenance passage 161 and the electrical space 13 are connected through the maintenance opening 122; and / or a wiring opening 121 is also formed on the side plate 12 for wiring to pass through.

[0054] The manhole 16, maintenance passage 161, and maintenance port 122 facilitate maintenance of the underground area. The wiring port 121 allows the battery compartment wiring to be led out from the side of the battery compartment base 10, which is convenient for collection, bundling, and maintenance.

[0055] Please see Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the overall structure of the energy storage facility provided in this embodiment of the utility model; Figure 6 This is a top view of the energy storage facility provided in an embodiment of this utility model.

[0056] To solve the above-mentioned technical problems, this utility model also discloses an energy storage facility, which includes: a battery compartment base 10 and a battery module 20 as described above, wherein the battery compartment base 10 supports the battery module 20.

[0057] Because the energy storage facility in this embodiment includes the aforementioned battery compartment base 10, the energy storage facility in this embodiment has at least the same technical effects as the battery compartment base 10, namely, it is less prone to structural damage due to land subsidence, and the battery module 20 operates stably.

[0058] In some embodiments of this application, the battery module 20 is disposed at the end of the side plate 12 away from the substrate 11, and the battery module 20 is connected to all the side plates 12.

[0059] The battery module 20 is located at the end of the side plate 12 away from the base plate 11 and is connected to all the side plates 12. That is, the battery module 20 is mounted across the electrical space 13. The electrical space 13 is empty and used for wiring and the placement of supporting equipment, and also provides space for personnel to perform maintenance.

[0060] Please see Figure 7 and Figure 8 As shown, Figure 7 This is a schematic diagram of the overall structure of an energy storage facility provided in another embodiment of the present invention; Figure 8 This is a cross-sectional view of an energy storage facility provided in another embodiment of the present invention.

[0061] In some embodiments of this application, there are multiple battery modules 20, and the battery modules 20 are disposed within the electrical space 13.

[0062] The battery module 20 is located within the electrical space 13, which facilitates the configuration mode of burying the entire energy storage facility underground.
