Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to an energy storage container base and an energy storage container. Background Technology

[0002] With the development of new energy technologies, energy storage containers have been increasingly widely used as a type of energy storage equipment. Energy storage containers are highly integrated energy storage devices, characterized by high integration, small footprint, ease of deployment, and relocation. An energy storage container consists of a base and a body. The base is equipped with battery racks for mounting battery modules. The energy storage capacity of an energy storage container is closely related to the number of battery modules that can be installed inside the container.

[0003] Existing energy storage container bases typically include a frame structure welded from outer crossbeams and outer longitudinal beams. Upper and lower base plates are welded to the upper and lower end faces of the frame structure, respectively. A battery rack mounting bracket is fixedly installed on the upper base plate. The battery rack is directly fixed on the upper part of the battery rack mounting bracket, and the battery rack mounting bracket provides an access channel for the cables below the battery rack.

[0004] In the existing technology, the overall height of the standard energy storage container of the same specification, the height of the outer crossbeam, the inner longitudinal beam of the base, and the height of the battery rack mounting bracket all have standard dimensions. As mentioned above, the existing standard energy storage container places the standard battery rack mounting bracket on top of the standard frame structure in its structural design, thereby using the battery rack mounting bracket to provide an access channel for the cables below the battery rack. However, this setting results in the battery rack mounting bracket being relatively high from the ground, which reduces the available space inside the energy storage container in the height direction of the battery rack. Consequently, it reduces the number of battery modules that can be arranged inside the energy storage container, resulting in poor energy storage capacity of the energy storage container.

[0005] Existing energy storage container base technology, such as the Chinese utility model patent with authorization announcement number CN211201281U, discloses "an energy storage container chassis and energy storage container." This energy storage container chassis (i.e., the aforementioned energy storage container) includes a rectangular structure welded together by two outer crossbeams and two inner crossbeams. Multiple inner crossbeams are arranged longitudinally at intervals within the rectangular structure, and two inner longitudinal beams are arranged transversely at intervals. Notches are provided on the inner longitudinal beams corresponding to the positions of the inner crossbeams, allowing the inner crossbeams to be snapped and fixed onto the inner longitudinal beams, and ensuring that the height of the inner crossbeams is flush with the frame structure. The beams, inner longitudinal beams, and outer longitudinal beams together enclose the battery rack mounting position. Two supporting longitudinal beams are spaced apart between the inner and outer longitudinal beams, and each supporting longitudinal beam has a notch corresponding to the position of the inner transverse beam. These notches allow the supporting longitudinal beams to be snapped and fixed onto the inner transverse beams, allowing the entire supporting longitudinal beam to be lowered into the frame structure. During installation, the battery rack is fixedly installed at the corresponding battery rack mounting position on the supporting transverse beam. A base plate is fixedly installed below the inner longitudinal beam. Simultaneously, a second cable hole is longitudinally drilled through the inner transverse beam, allowing cables to enter and exit below the battery rack. In this way, the notches in the inner and supporting longitudinal beams allow them to be lowered into the rectangular structure, preventing a reduction in usable space above the battery rack height due to its high ground clearance. This allows for the installation of more battery modules above the battery rack height, increasing the overall energy storage capacity of the energy storage container. The second cable hole in the inner transverse beam also allows cables below the battery rack to enter and exit.

[0006] However, the aforementioned energy storage container chassis reduces the height of the battery mounting rack by creating notches in the inner and supporting longitudinal beams to lower them into the rectangular structure. At the same time, to allow cables to enter and exit, a second cable hole inevitably needs to be created on the inner crossbeam. Although this reduces the height of the battery rack from the ground, it also damages the overall structure of the inner longitudinal beams, supporting longitudinal beams, and inner crossbeams, thus reducing the load-bearing capacity of the energy storage container chassis. Although the energy storage container can provide a large installation space in the height direction of the battery rack, the limited load-bearing capacity of the energy storage container chassis prevents it from supporting a large number of battery modules, resulting in poor energy storage capacity of the energy storage container. Summary of the Invention

[0007] The purpose of this invention is to provide an energy storage container base to solve the technical problem that the energy storage container base in the prior art cannot support a large number of battery modules, resulting in poor energy storage capacity of the energy storage container; the purpose of this invention is also to provide an energy storage container to solve the technical problem that the energy storage container in the prior art cannot support a large number of battery modules, resulting in poor energy storage capacity of the energy storage container.

[0008] To achieve the above objectives, the technical solution of the energy storage container base of the present invention is as follows:

[0009] An energy storage container base includes a frame structure. The frame structure includes main crossbeams arranged longitudinally at intervals. The height of the main crossbeams is greater than the height of a standard outer crossbeam. Multiple inner longitudinal beams are fixed transversely at intervals between adjacent main crossbeams and are located inside the frame structure. Battery rack mounting brackets for supporting battery racks are provided on the inner longitudinal beams. The sum of the heights of the inner longitudinal beams and the battery rack mounting brackets is less than the sum of the heights of the standard inner longitudinal beams and the standard battery rack mounting brackets. A cable channel for the entry and exit of cables below the battery rack is provided between the battery rack mounting surface and the inner longitudinal beams of the battery rack mounting brackets.

[0010] Beneficial Effects: This invention innovatively designs a base for an energy storage container. The height of the main crossbeam is greater than that of a standard main crossbeam, enhancing its strength. The battery rack mounting bracket is positioned above the inner longitudinal beam, preserving its structural integrity and relatively increasing the overall strength and load-bearing capacity of the energy storage container base. Furthermore, the sum of the heights of the inner longitudinal beam and the battery rack mounting bracket is less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket, expanding the installation space within the energy storage container in the battery rack height direction. This allows for the placement of more battery modules within a standard-height energy storage container, increasing its energy storage capacity. Simultaneously, the cable channel facilitates the entry and exit of cables below the battery rack. Therefore, the energy storage container base of this invention, through its structural design, possesses both sufficient load-bearing capacity and enables the energy storage container to achieve higher energy storage capacity. In summary, the energy storage container base of this invention solves the technical problem of poor energy storage capacity in existing energy storage container bases due to their inability to support a large number of battery modules.

[0011] Furthermore, the sum of the heights of the inner longitudinal beam and the battery rack mounting bracket is equal to the height of the main cross beam.

[0012] Beneficial effects: The above design can create a flat mounting surface on the energy storage container, which facilitates the installation of battery racks and other internal components of the energy storage container.

[0013] Furthermore, the inner longitudinal beam is provided with a group of supporting crossbeams arranged at intervals along the longitudinal direction. Two supporting crossbeams form a group to constitute a battery rack mounting bracket, and the space between the two supporting crossbeams forms the cable channel.

[0014] Beneficial effects: Through the above design, the supporting beams are used as mounting brackets for the battery rack. On the one hand, the supporting beams, inner longitudinal beams and main beams are interlocked and fixed, which can improve the overall strength of the energy storage container base and increase the load-bearing capacity. On the other hand, the cable channel is directly formed under the supporting beams, which facilitates the entry and exit of cables under the battery rack. The structure is compact.

[0015] Furthermore, the main crossbeam is a steel beam with a groove in its cross section. The grooves on the opposite sides of two adjacent main crossbeams respectively form fixed grooves. The two ends of the inner longitudinal beam extend into the fixed grooves on the corresponding sides and are fixedly installed on the lower groove wall of the corresponding fixed groove.

[0016] Beneficial effects: By designing the main crossbeam as a steel beam with a grooved cross section, the bending strength of the main crossbeam can be enhanced by bending, thereby improving the load-bearing capacity of the energy storage container base. On the other hand, the fixed groove can support the inner longitudinal beam, making the fixation between the inner longitudinal beam and the main crossbeam more secure, and thus making the overall strength of the energy storage container base higher.

[0017] Furthermore, the main crossbeam is an I-beam, and a bending support plate is connected between the upper and lower flanges on the opposite sides of the two outermost main crossbeams.

[0018] Beneficial effects: Through the above design, the torsional strength of the main crossbeam can be enhanced by using the bending support plate, thereby improving the overall strength of the energy storage container and thus increasing the load-bearing capacity of the energy storage container.

[0019] Furthermore, within the frame structure, two sets of battery rack mounting brackets are arranged at transverse intervals, with the two sets of battery rack mounting brackets being symmetrically arranged. Between the two sets of battery rack mounting brackets, a rack mounting longitudinal beam for mounting the rack is provided.

[0020] Beneficial effects: By arranging the cabinet mounting beams between the two battery rack mounting brackets through the above design, the internal space can be fully utilized, making the overall structure more compact. At the same time, the two sets of battery rack mounting brackets are arranged symmetrically in the transverse direction, which can make the center of gravity of the entire energy storage container closer to the middle position, thereby increasing the stability during hoisting and transportation and improving the practicality of the energy storage container base.

[0021] Furthermore, a manhole module is also installed between the two sets of battery rack mounting brackets.

[0022] Beneficial effects: The above design makes full use of the internal space, resulting in a more compact structure.

[0023] To achieve the above objectives, the technical solution of the energy storage container of the present invention is as follows:

[0024] The energy storage container includes an energy storage container base and a container body. The energy storage container base includes a frame structure, which includes main crossbeams arranged longitudinally at intervals. The height of the main crossbeams is greater than the height of the standard outer crossbeams. Multiple inner longitudinal beams are fixed between adjacent main crossbeams at transverse intervals inside the frame structure. Battery rack mounting brackets for supporting battery racks are provided on the inner longitudinal beams. The sum of the heights of the inner longitudinal beams and the battery rack mounting brackets is less than the sum of the heights of the standard inner longitudinal beams and the standard battery rack mounting brackets. The battery rack mounting brackets have cable channels for the entry and exit of cables below the battery rack between their battery rack mounting surfaces and the inner longitudinal beams.

[0025] Beneficial Effects: The energy storage container of this invention improves the base of the energy storage container by making the height of the main crossbeam greater than that of the standard main crossbeam, thereby enhancing the strength of the main crossbeam. The battery rack mounting bracket is arranged above the inner longitudinal beam without compromising the integrity of the inner longitudinal beam structure, thus relatively improving the overall strength of the energy storage container base and increasing its load-bearing capacity. Furthermore, the sum of the heights of the inner longitudinal beam and the battery rack mounting bracket is less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket, expanding the installation space inside the energy storage container in the height direction of the battery rack. This allows for the placement of more battery modules within the standard-height energy storage container, increasing its energy storage capacity. Simultaneously, the cable channel facilitates the entry and exit of cables below the battery rack. Therefore, the energy storage container base of this invention, through its structural design, possesses both sufficient load-bearing capacity and enables the energy storage container to achieve higher energy storage capacity. In summary, the energy storage container of this invention solves the technical problem of poor energy storage capacity in existing energy storage containers due to the inability of the base to support a large number of battery modules.

[0026] Furthermore, the sum of the heights of the inner longitudinal beam and the battery rack mounting bracket is equal to the height of the main cross beam.

[0027] Beneficial effects: The above design can create a flat mounting surface on the energy storage container, which facilitates the installation of battery racks and other internal components of the energy storage container.

[0028] Furthermore, the inner longitudinal beam is provided with a group of supporting crossbeams arranged at intervals along the longitudinal direction. Two supporting crossbeams form a group to constitute a battery rack mounting bracket, and the space between the two supporting crossbeams forms the cable channel.

[0029] Beneficial effects: Through the above design, the supporting beams are used as mounting brackets for the battery rack. On the one hand, the supporting beams, inner longitudinal beams and main beams are interlocked and fixed, which can improve the overall strength of the energy storage container base and increase the load-bearing capacity. On the other hand, the cable channel is directly formed under the supporting beams, which facilitates the entry and exit of cables under the battery rack. The structure is compact.

[0030] Furthermore, the main crossbeam is a steel beam with a groove in its cross section. The grooves on the opposite sides of two adjacent main crossbeams respectively form fixed grooves. The two ends of the inner longitudinal beam extend into the fixed grooves on the corresponding sides and are fixedly installed on the lower groove wall of the corresponding fixed groove.

[0031] Beneficial effects: By designing the main crossbeam as a steel beam with a grooved cross section, the bending strength of the main crossbeam can be enhanced by bending, thereby improving the load-bearing capacity of the energy storage container base. On the other hand, the fixed groove can support the inner longitudinal beam, making the fixation between the inner longitudinal beam and the main crossbeam more secure, and thus making the overall strength of the energy storage container base higher.

[0032] Furthermore, the main crossbeam is an I-beam, and a bending support plate is connected between the upper and lower flanges on the opposite sides of the two outermost main crossbeams.

[0033] Beneficial effects: Through the above design, the torsional strength of the main crossbeam can be enhanced by using the bending support plate, thereby improving the overall strength of the energy storage container and thus increasing the load-bearing capacity of the energy storage container.

[0034] Furthermore, within the frame structure, two sets of battery rack mounting brackets are arranged at transverse intervals, with the two sets of battery rack mounting brackets being symmetrically arranged. Between the two sets of battery rack mounting brackets, a rack mounting longitudinal beam for mounting the rack is provided.

[0035] Beneficial effects: By arranging the cabinet mounting beams between the two battery rack mounting brackets through the above design, the internal space can be fully utilized, making the overall structure more compact. At the same time, the two sets of battery rack mounting brackets are arranged symmetrically in the transverse direction, which can make the center of gravity of the entire energy storage container closer to the middle position, thereby increasing the stability during hoisting and transportation and improving the practicality of the energy storage container base.

[0036] Furthermore, a manhole module is also installed between the two sets of battery rack mounting brackets.

[0037] Beneficial effects: The above design makes full use of the internal space, resulting in a more compact structure. Attached Figure Description

[0049] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0050] Specific embodiment 1 of the energy storage container provided by the present invention:

[0051] The energy storage container of this invention designs its base structure such that the height of the main crossbeam is greater than that of the standard outer crossbeam, thereby increasing the overall strength of the main crossbeam and ensuring sufficient load-bearing capacity of the energy storage container. It also makes the sum of the heights of the inner longitudinal beams and the battery rack mounting brackets less than the sum of the heights of the standard inner longitudinal beams and the standard battery rack mounting brackets. This expands the installation space inside the energy storage container in the battery rack height direction, allowing more battery modules to be installed inside the standard-height energy storage container, thus increasing the energy storage capacity of the container. Therefore, the energy storage container base of this invention not only ensures that there is space to install more battery modules but also ensures sufficient load-bearing capacity to support a larger number of battery modules, thereby improving the energy storage capacity of the energy storage container.

[0052] In the prior art, there are standard requirements for the height of the same model of energy storage container and the energy storage and energy storage container base. In this embodiment, taking a 45-foot energy storage container as an example, in the prior art, the height of the standard outer crossbeam of the standard 45-foot energy storage container base is 200mm, the height of the standard inner longitudinal beams arranged between the two standard outer crossbeams is 200mm, and the height of the standard battery rack mounting bracket installed on the standard inner longitudinal beam is 80mm. Therefore, the height of the standard 45-foot battery rack from the ground is the sum of the heights of the standard inner longitudinal beams and the standard battery rack mounting brackets, which is 280mm. In order to ensure the support strength, the spacing between each standard inner longitudinal beam is generally between 200mm and 300mm.

[0053] In this embodiment, for ease of description, the length direction of the main crossbeam 7 is defined as the front-to-back direction, and the length direction of the main longitudinal beam 10 is defined as the left-to-right direction.

[0054] In this embodiment, specifically, as Figure 1 As shown, the energy storage container includes an energy storage container base (hereinafter referred to as the base) and a container structure (not shown in the figure). A battery rack (not shown in the figure), a cabinet (not shown in the figure), and a manhole module 5 for circuit maintenance are fixedly installed on the upper end of the base.

[0055] Among them, such as Figure 1 ,3 As shown, the main frame 1 of the base includes a frame structure. The frame structure includes two main crossbeams 7 spaced apart in the left-right direction. Two main longitudinal beams 10 are respectively provided at the front and rear ends of the main crossbeams 7, and the main crossbeams 7 and main longitudinal beams 10 are at the same height. A lifting corner piece 9 is provided on the left and right sides of each main longitudinal beam 10, with its two sides fixed to the main crossbeams 7 and 10 respectively. Thus, the main crossbeams 7, main longitudinal beams 10, and corner pieces 9 form a frame structure with flush upper surfaces. In this embodiment, the height of the main crossbeams 7 is 244mm, which is higher than the height of the standard outer crossbeam. This enhances the torsional strength of the main crossbeams 7, thereby improving the support strength and load-bearing capacity of the entire energy storage container base.

[0056] Multiple lifting modules 11 for hoisting are provided on the left and right sides of the frame structure along the front and back direction. Circular holes extending in the left and right direction are opened on the main crossbeam 7. The hoisting device is installed in the circular holes. The lifting module 11 includes front and rear baffles, lifting bushings, lifting shafts, and retaining rings. The front and rear fixed plates and lifting bushings are welded to the main frame 1 of the base as a whole. After the lifting shaft passes through the lifting bushing, retaining rings and baffles are welded to both ends to limit the movement. The lifting shaft is a movable part that can extend and retract within the lifting bushing. The lifting shaft can be pulled out during hoisting.

[0057] like Figure 3 , 4 As shown in Figure 5, in this embodiment, multiple inner longitudinal beams 8 are arranged at equal intervals along the transverse direction between the two main crossbeams 7, and the inner longitudinal beams 8 are G-shaped beams with a height of 164mm. In this embodiment, the main crossbeams 7 are I-beams, and the grooves on the opposite sides of the two main crossbeams 7 are fixed grooves. The left and right ends of the inner longitudinal beams 8 extend into the fixed grooves of the corresponding main crossbeams 7 and are welded and fixed to the lower flange of the fixed grooves. In this way, on the one hand, the steel sections with bent cross-sections, such as I-beams and G-shaped beams, can make the base have higher strength and improve the load-bearing capacity of the base. On the other hand, fixing the inner longitudinal beams 8 to the lower flange of the fixed grooves can use the stronger main crossbeams 7 to support and protect the inner crossbeams, while enhancing the connection strength between the main crossbeams 7 and the inner longitudinal beams 8, making the fixation between the two more reliable, and further enhancing the overall strength of the base.

[0058] In this embodiment, the main crossbeam 7, as the primary load-bearing component, is designed to be relatively high, which significantly improves the load-bearing capacity of the entire base. Therefore, in this embodiment, the height of each inner longitudinal beam 8 can be reduced to 164mm, and the spacing between each inner longitudinal beam 8 can be designed to be 625mm to meet the strength requirements of the entire energy storage container. This arrangement saves costs, makes the overall design simpler, and relatively reduces the weight of the entire base. In other embodiments, while ensuring sufficient strength of the container base, the spacing between each inner longitudinal beam 8 can be adjusted according to actual needs, such as 550mm, 600mm, 700mm, etc.

[0059] In this embodiment, bending support plates 15 are provided in the opposite grooves of the two main crossbeams 7, and the upper and lower ends of the bending support plates 15 are welded and fixed to the upper and lower flanges of the grooves, respectively. The bending support plates 15 improve the torsional strength of the main crossbeams 7, thereby increasing the overall strength and load-bearing capacity of the base. In this embodiment, multiple bending support plates 15 are arranged at intervals along the front-to-back direction. This improves the torsional strength of the main crossbeams 7 while making the overall structure simpler and avoiding interference with the lifting module 11.

[0060] In this embodiment, the length of the main crossbeam 7 is greater than the length of the inner longitudinal beam 8, so that the entire frame structure is slender in the front-to-back direction. In this way, in the same type of energy storage container, the length of the lower-strength inner longitudinal beam 8 can be relatively reduced, so that the higher-strength main crossbeam 7 can serve as the main load-bearing body, avoiding deformation of the inner longitudinal beam 8 under stress during the load-bearing process, and ensuring that the energy storage container base has a high load-bearing capacity.

[0061] In this embodiment, as Figure 3 As shown, within the frame structure, a battery rack mounting bracket 12 is installed on the inner longitudinal beam 8 to support the battery rack. The sum of the heights of the inner longitudinal beam 8 and the battery rack mounting bracket 12 is less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket 12. This reduces the height of the battery rack from the ground, ensuring more installation space in the vertical direction of the battery rack inside the container. A cable channel is provided between the battery rack mounting surface of the battery rack mounting bracket 12 and the inner longitudinal beam 8 for the entry and exit of cables below the battery rack. This arrangement ensures more usable space in the vertical direction of the battery rack inside the container, allowing more battery modules to be installed within the container. Furthermore, the design of the outer crossbeam and the inner longitudinal beam 8 ensures that the entire base has sufficient load-bearing capacity to support more battery modules, thereby increasing the overall energy storage capacity of the container.

[0062] Specifically, within the frame structure, two sets of battery rack mounting brackets 12 are arranged at intervals along the front-to-back direction, and the two sets of battery rack mounting brackets 12 are symmetrically arranged. Each set of battery rack mounting brackets 12 includes four supporting crossbeams 121 arranged at intervals along the left-to-right direction on the inner longitudinal beam 8, such as... Figure 4 , 5 As shown, the lower end of the supporting crossbeam 121 is welded and fixed to the inner longitudinal beam 8. Two beams form a group to constitute the battery rack mounting bracket 12, and the space between the two supporting crossbeams 121 forms a channel for cables to enter and exit below the battery rack. This arrangement, with the two groups of battery rack mounting brackets 12 symmetrically arranged, allows the center of gravity of the energy storage container to be closer to the center after assembly, thus improving stability during hoisting and transportation and enhancing the practicality of the base. Using the supporting crossbeam 121 as the battery rack mounting bracket 12 provides two advantages: firstly, the overlapping and fixing of the supporting crossbeam 121 with the inner longitudinal beam 8 and the main crossbeam 7 makes the base structure more stable, improving the overall strength and load-bearing capacity of the base; secondly, a cable channel can be directly formed below the supporting crossbeam 121, facilitating the entry and exit of cables below the battery rack, resulting in a compact structure.

[0063] In this embodiment, the sum of the heights of the inner longitudinal beam 8 and the battery rack mounting bracket 12 is equal to the height of the main crossbeam 7. In this embodiment, the height of the main crossbeam 7 is 244mm, and the height of the inner longitudinal beam 8 is 164mm. Therefore, the height of the supporting crossbeam 121 is the same as the height of the standard battery rack mounting bracket 12, which is 80mm. Thus, in this embodiment, the height of the battery rack from the ground is 244mm, while the height of the battery rack of a standard 45-foot energy storage container from the ground is 280mm. Therefore, this arrangement can reduce the height of the battery rack from the ground and form a flat mounting surface above the base, which facilitates the installation of the battery rack and other components. Furthermore, the fact that the height of the supporting crossbeam 121 is 80mm, the same as the height of the standard battery rack mounting bracket 12, can reduce the types of steel used in actual production and facilitate production.

[0064] like Figure 1 , 2 As shown, a long, narrow cable channel base plate 4 is laid below the battery rack mounting bracket 12. The bottom surface of the cable channel base plate 4 is fixed to the inner longitudinal beam 8, and the cable channel base plate 4 extends through the battery rack mounting bracket 12 in the front-to-back direction. This allows cables to be arranged on the cable channel base plate 4, avoiding cable clutter, facilitating actual operation, and supporting the cables to prevent them from sagging and being damaged under gravity. Simultaneously, since the supporting beam 121 is located above the inner longitudinal beam 8, the cable channel has no obstruction in the length direction, making cable routing more convenient. Multiple cable bundling clips 41 are spaced apart above the cable channel base plate 4, which can be used to organize the cables within the cable channel.

[0065] like Figure 3 As shown, three rack mounting longitudinal beams 13 are arranged at intervals along the front-to-back direction between the two sets of battery rack mounting brackets 12. These three longitudinal beams 13 are positioned between the two inner longitudinal beams 8 in the middle of the frame structure. The height of the rack mounting longitudinal beams 13 is the same as the height of the main crossbeams 7. Their left and right ends are welded and fixed to the opposite sides of the two main crossbeams 7, and their top surfaces are flush with the top surface of the frame structure. This arrangement places the rack in the middle, bringing the center of gravity of the entire container closer to the center and ensuring stability during container lifting and transportation. Simultaneously, placing the rack mounting brackets 6 in the middle facilitates the cabling between the battery racks above the two sets of battery rack mounting brackets 12 and the rack.

[0066] like Figure 1 , 3 As shown, a manhole module 5 is also provided between the two sets of battery rack mounting brackets 12. Specifically, a manhole mounting beam 14 is fixedly installed between the two sets of rear cabinet mounting beams 13. The manhole mounting beam 14, together with the main crossbeam 7 and the two rear cabinet mounting beams 13, constitutes the manhole module 5 mounting position. An openable door panel is provided above the manhole module 5 mounting position. In actual operation, the operator opens the door panel and descends into the manhole to perform relevant operations. The manhole module 5 is existing technology and will not be described in detail here. This makes full use of the internal space, making the overall structure more compact.

[0067] like Figure 1 , 2 As shown, a rack mounting bracket 6 is fixedly installed above the rack mounting beam 13, and the rack is fixedly installed above the rack mounting bracket 6, as shown. Figure 3 As shown, through holes for cable routing are provided on the longitudinal beam 13 of the cabinet mounting, corresponding to the cable channel position. Through holes for cable routing are also provided on the longitudinal beam 14 of the manhole mounting. In other embodiments, the position and spacing of the longitudinal beam 13 of the cabinet mounting and the longitudinal beam 14 of the manhole mounting can be adjusted according to the actual project.

[0068] like Figure 1 , 2 As shown, in this embodiment, a lower base plate 2 is fixedly installed at the bottom of the frame structure by full welding. The lower base plate 2 can prevent moisture from entering the container and protect the internal components. At the upper end of the frame structure, away from the cable channel base plate 4 and the door panel of the manhole module 5, an upper base plate 3 is laid flat and fixed therein, and a cabinet cable routing hole is left on the upper base plate 3.

[0069] In other embodiments, the structural design of this invention, which increases the load-bearing capacity of the base by increasing the height of the main crossbeam 7 and increases the number of battery modules inside the container by making the sum of the heights of the inner longitudinal beam 8 and the battery rack mounting bracket 12 less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket, can also be applied to increase the energy storage capacity of other specifications of energy storage containers.

[0070] In this embodiment, a standard 45-foot energy storage container is used as an example. In other specifications of energy storage containers, the height of the outer crossbeam of the other specifications of standard energy storage containers is the height of the standard outer crossbeam referred to in this invention, the height of the inner longitudinal beam of the other specifications of standard energy storage containers is the height of the standard inner longitudinal beam referred to in this invention, and the height of the battery rack mounting bracket of the other specifications of standard energy storage containers is the height of the standard battery rack mounting bracket referred to in this invention.

[0071] In this embodiment, the height of the main crossbeam 7 is 244mm, the height of the inner longitudinal beam 8 is 164mm, and the height of the battery rack mounting bracket 12 is 80mm. The sum of the heights of the inner longitudinal beam 8 and the battery rack mounting bracket 12 is 244mm. This is just one specific value. In other embodiments, the height of the main crossbeam 7 can also be other values ​​not less than 200mm, such as 220mm, 250mm, 270mm, etc. Preferably, the height of the main crossbeam 7 is between 200mm and 280mm, and the sum of the heights of the inner longitudinal beam 8 and the battery rack mounting bracket 12 is preferably between 200mm and 280mm, such as 220mm, 255mm, 275mm, etc. In this embodiment, the height of the battery rack from the ground is reduced by decreasing the height of the inner longitudinal beam 8 relative to the standard inner longitudinal beam height, while keeping the height of the battery rack mounting bracket 12 unchanged from the standard battery rack mounting bracket height. In other embodiments, the height of the battery rack from the ground can be reduced by decreasing the heights of both the inner longitudinal beam 8 and the battery rack mounting bracket 12.

[0072] In summary, the energy storage container of the present invention, by ensuring that the height of the battery rack mounting bracket 12 and the inner longitudinal beam 8 is always lower than the ground height of the standard battery rack, can guarantee that more battery modules can be installed inside the energy storage container. Through the design of the dimensions of the main crossbeam 7, the strength of the entire base can be improved, ensuring that the load-bearing capacity of the base is increased and can support more battery modules. Therefore, the energy storage capacity of the entire energy storage container is improved, solving the technical problem of poor energy storage capacity of existing energy storage containers due to the inability of the energy storage container base to support more battery modules.

The inside of the square frame structure is the cable channel. Through holes for cable routing are opened on the side of the square frame structure facing the rack mounting longitudinal beam.

[0077] Embodiment 6 of the energy storage container of the present invention: The difference between this embodiment and Embodiment 1 is that this embodiment provides a type of battery rack mounting bracket. In Embodiment 1, the sum of the heights of the inner longitudinal beam and the battery rack mounting bracket is equal to the height of the main crossbeam. In this embodiment, provided that the base has sufficient load-bearing capacity, the sum of the heights of the inner crossbeam and the battery rack mounting bracket can be greater than the sum of the heights of the main crossbeam, as long as the sum of their heights is less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket. In other embodiments, provided that the base has sufficient load-bearing capacity, the sum of the heights of the inner crossbeam and the battery rack mounting bracket can be less than the sum of the heights of the main crossbeam, as long as the sum of their heights is less than the sum of the heights of the standard inner longitudinal beam and the standard battery rack mounting bracket.

[0078] Embodiment 7 of the energy storage container of the present invention: The difference between this embodiment and Embodiment 1 is that this embodiment provides a manhole module with a specific arrangement.
