Description

[Technical Field]

[0001] This application claims priority from a utility model application bearing application number 202320694413.9 and entitled "Energy Storage Device" filed with the China Patent Office on March 31, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of energy storage technology, and in particular to energy storage devices. [Background technology]

[0003] Current energy storage devices require pre-drilling holes in the ground before being secured to the ground, and then bolts are inserted through assembly holes in the bottom support structure and into holes in the ground to secure the energy storage device to the ground. However, this method has the problem that the assembly holes on the support structure and the holes in the ground may not be perfectly aligned, making assembly difficult. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of these, an embodiment of the present application provides an energy storage device that can improve assembly efficiency when fixing the energy storage device to the ground. [Means for solving the problem]

[0005] In a first aspect, an energy storage device is provided, comprising: a device body; and a support structure; the support structure is installed at the bottom of the device body and is used to support the device body; wherein the support structure comprises a first support plate; the first support plate comprises a first mounting wall; the orthogonal projection of the first mounting wall on a first plane is located outside the orthogonal projection of the device body on the first plane; the first mounting wall is provided with a first assembly hole for fixing the device body to the ground; and the first plane is perpendicular to the gravity direction of the device body.

[0006] In this embodiment, on the one hand, the orthogonal projection of the first mounting wall on the first plane, on which the first assembly hole of the support structure is installed, is located outside the orthogonal projection of the device body on the first plane, and the first assembly hole and the device body are horizontally offset, thereby providing the drilling device with horizontally operable space. This has the advantage of making drilling and installation easier compared to a method in which the orthogonal projection of the first mounting wall on the first plane is located inside the orthogonal projection of the device body on the first plane. On the other hand, with this installation, after the energy storage device is moved to the designated installation area, holes can be drilled in the ground corresponding to the position of the first assembly hole. This improves or solves the problem of the assembly holes of the support structure and the drilled holes in the ground not matching up during installation, which occurs when drilling in a designated installation area in advance, and further improves the assembly efficiency of the energy storage device.

[0007] In one possible embodiment, the first support plate further includes a second mounting wall connected to the first mounting wall, the orthogonal projection of the second mounting wall on the first plane being located inside the orthogonal projection of the device body on the first plane, and the second mounting wall is provided with a second assembly hole for fixing the device body to the ground.

[0008] In this embodiment, the first support plate includes a first mounting wall whose orthogonal projection on the first plane is located outside the orthogonal projection of the device body on the first plane, and further includes a second mounting wall whose orthogonal projection on the first plane is located inside the orthogonal projection of the device body on the first plane, and a second assembly hole is provided in the second mounting wall. On the one hand, when there is insufficient horizontal mounting space, it is convenient for workers to use the second assembly hole to fix the energy storage device to the ground. On the other hand, when there is sufficient horizontal mounting space, it is convenient for workers to use both the first and second assembly holes to mount the energy storage device, which can save mounting space and improve the stability of the energy storage device.

[0009] In one possible embodiment, the first support plate is a flat plate.

[0010] In this embodiment, the first support plate is installed on a flat plate, which saves the space occupied by the first support plate and also makes it easier to process the first support plate. At the same time, because the first support plate is a flat plate, the first mounting wall and the second mounting wall are two parts located on the same plane of the first support plate, which not only makes it easier to drill assembly holes, but also saves costs and ensures processing and assembly efficiency.

[0011] In one possible embodiment, the first mounting wall and the second mounting wall are integrally formed.

[0012] In this embodiment, by integrally molding the first mounting wall and the second mounting wall, the connection strength between the first mounting wall and the second mounting wall can be strengthened, and the stability and reliability of the energy storage device can be improved.

[0013] In one possible embodiment, the support structure further includes a fixing member, which protrudes in a direction away from the first support plate compared to the first support plate, and the fixing member is connected between the device body and the first support plate.

[0014] In this embodiment, on the one hand, the fixing member can connect the device body and the first support plate, thereby enabling the support structure to realize the function of supporting the device body; on the other hand, the fixing member can raise the height of the device body, provide more installation space for the first support plate, and ensure the reliability, stability, and convenience of the installation of the energy storage device.

[0015] In one possible embodiment, the orthogonal projections of the first mounting wall and the second mounting wall in the first plane are located on either side of the orthogonal projection of the fixing member in the first plane, respectively.

[0016] In this embodiment, the orthogonal projections of the first mounting wall and the second mounting wall on the first plane are located on both sides of the orthogonal projection of the fixing member on the first plane, which is advantageous in reducing the amount of material used in the support structure, thereby reducing the cost of the energy storage device.

[0017] In one possible embodiment, the dimension of the first mounting wall is smaller than the dimension of the second mounting wall in the horizontal direction.

[0018] In this embodiment, the horizontal dimension of the first mounting wall is smaller than the dimension of the second mounting wall, so that the gap between the energy storage devices can be reduced as much as possible, thereby improving the integration of multiple energy storage devices.

[0019] In one possible embodiment, a gasket is provided on the bottom surface of the first support plate.

[0020] In this embodiment, adding a gasket to the bottom surface of the first support plate may be advantageous to reduce the probability of wear and / or rust on the bottom coating layer of the support structure.

[0021] In one possible embodiment, the gasket and the first support plate are fixedly connected via a rivet nut.

[0022] In this embodiment, the use of rivet nuts to fasten the first support plate and the gasket together provides a reliable, low-cost connection that is easy to use; at the same time, the use of rivets to connect the gasket and the first support plate reduces the space occupied by the rivet process, simplifies the installation and operation process, and improves operation efficiency.

[0023] In one possible embodiment, a protective plate is installed at the bottom of the device body.

[0024] In this embodiment, a protective plate is added to the bottom of the device body to prevent the forklift arms from damaging the contact surface coating layer on the bottom of the device body when the energy storage device is transported by the forklift.

[0025] In one possible embodiment, the protection plate is installed at the edge area of ​​the bottom of the device body.

[0026] In this embodiment, the protective plate is installed in the edge region of the bottom of the device body, and the protective plate does not need to completely cover the bottom of the device body; that is, the protective plate only needs to cover the bottom of the device body and the area that can be contacted by a forklift, which prevents the forklift arm from damaging the contact surface coating layer on the bottom of the device body and reduces the amount of material used for the protective plate, thereby reducing costs.

[0027] In one possible embodiment, the support structure further includes a second support plate, the orthogonal projection of the second support plate on the first plane being located inside the orthogonal projection of the device body on the first plane, and the second support plate is provided with a third assembly hole for fixing the device body to the ground.

[0028] In this embodiment, the support structure includes a first assembly hole whose orthogonal projection on a first plane perpendicular to the gravity direction is located outside the orthogonal projection on the first plane of the device body, and further includes a third assembly hole whose orthogonal projection on the first plane is located inside the orthogonal projection on the first plane of the device body, thereby allowing the drilling device to perform on-site drilling outside the device body, improving assembly efficiency and strengthening the fixation between the device body and the ground.

[0029] In one possible embodiment, the support structure includes at least one pair of first support plates, each pair of first support plates includes two first support plates, at least one second support plate is installed corresponding to each pair of first support plates, the two first support plates in each pair of first support plates are installed at a distance from each other on the bottom of the device body, and the second support plate is installed between the two first support plates.

[0030] In this embodiment, the two first support plates in each pair of first support plates are installed at a distance from each other at the bottom of the device body, and the second support plate is installed between the two first support plates, which is advantageous for the support structure to provide uniform support force to the device body, thereby improving the stability of the energy storage device.

[0031] In a second aspect, there is provided a method for installing an energy storage device according to the first aspect and any one possible embodiment thereof, the method including: placing the energy storage device in a predetermined installation area; drilling holes in the ground within the predetermined installation area corresponding to first assembly holes; and inserting bolts into the first assembly holes and the holes drilled in the ground to secure the energy storage device to the ground.

Those skilled in the art will be able to understand the specific meanings of the above terms in the present application depending on the specific circumstances.

[0036] The term "and / or" in this application is simply a relation that describes related objects and indicates that three types of relations can exist. For example, A and / or B can indicate three cases: the presence of A, the simultaneous presence of A and B, and the presence of B.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art will understand, both explicitly and implicitly, that the embodiment described in this application may be combined with other embodiments.

[0039] Typically, the energy storage device may include a battery compartment within which an assembly such as a plurality of batteries, main control components, bus components, and thermal management components may be disposed.

[0040] A battery includes a case and one or more battery cells enclosed in the case, and is also referred to as a battery case. Optionally, the battery cells may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium batteries, sodium-ion batteries, or magnesium-ion batteries, and the embodiments of the present application are not limited thereto. The battery cells may be cylindrical, flat, rectangular, or have other shapes, and the embodiments of the present application are not limited thereto.

[0041] Optionally, the plurality of batteries disposed in the battery compartment can be connected in series, parallel, or series-parallel to each other. In some embodiments, the plurality of batteries can be connected to a main control member via a bus member, and electrical connection between the plurality of batteries is achieved via the main control member.

[0042] In addition to the plurality of batteries, main control components, and bus components, the energy storage device further includes thermal management components, including, but not limited to, an air conditioning assembly, a fan assembly, a water-cooled duct, etc., which are used to thermally manage the interior of the energy storage device and thereby regulate the temperature inside the energy storage device.

[0043] Typically, energy storage devices are generally fixed to the ground via a support structure. Specifically, assembly holes are provided on the support structure, and pre-drilling is performed within a predetermined installation area using a drilling device prior to installation. The energy storage device is then moved into the predetermined installation area, and the assembly holes on the support structure are aligned with the drilled holes in the ground. Finally, bolts are passed through the assembly holes on the support structure and inserted into the drilled holes in the ground to fix the energy storage device to the ground. With current energy storage devices, the assembly holes on the support structure and the drilled holes in the ground may not be perfectly aligned, which can lead to problems such as difficulty or insufficient assembly.

[0044] After in-depth research, it was found that the reason why the assembly holes and the drilling holes cannot be perfectly aligned in the related art is that the drilling holes of the support structure are located directly below the energy storage device, making it inconvenient to align the assembly holes and the drilling holes during installation. Thus, the present application provides an energy storage device, comprising: a device body and a support structure installed on the bottom of the device body, the support structure including a first support plate, and the first support plate including a first mounting wall in which a first assembly hole is installed, the first mounting wall having an orthogonal projection of the energy storage device on a first plane perpendicular to the direction of gravity located outside the orthogonal projection of the device body on the first plane. On the one hand, the first assembly hole and the device body are horizontally offset, providing a horizontal operating space for the drilling device, which has the advantage of making drilling and installation easier than a method in which the orthogonal projection of the first mounting wall on the first plane is located inside the orthogonal projection of the device body on the first plane. On the other hand, with such installation, after the energy storage device is moved to a predetermined installation area, holes can be drilled in the ground corresponding to the positions of the first assembly holes. This improves or solves the problem of the assembly holes in the support structure not matching the drilled holes in the ground during installation, which occurs when drilling holes in a predetermined installation area in advance, and further improves the assembly efficiency of the energy storage device.

[0045] Fig. 1 shows a front view of an energy storage device 100 provided according to an embodiment of the present application. Fig. 2 shows a bottom view of the energy storage device 100 provided according to an embodiment of the present application. As shown in Figs. 1 and 2, the energy storage device 100 includes a device body 110 and a support structure 120, of which the device body 110 is the main structure of the energy storage device 100, and the support structure 120 is installed at the bottom of the device body 110 and is used to support and mount the device body 110.

[0046] The support structure 120 includes a first support plate 121, which includes a first mounting wall 1211, the orthogonal projection Y of the first mounting wall 1211 on the first plane X being located outside the orthogonal projection Z of the device body 110 on the first plane X, the first mounting wall 1211 having a first assembly hole 1211a for fixing the device body 110 to the ground, and the first plane X being perpendicular to the gravity direction G of the device body 110 (as shown in FIG. 1 , the angle between the first plane X and the gravity direction G is 90°).

[0047] It should be noted that the orthogonal projection Y of the first mounting wall 1211 on the first plane X refers to the projection of the first mounting wall 1211 on the first plane X along the gravity direction G, and the orthogonal projection Y of the device body 110 on the first plane X refers to the projection of the device body 110 on the first plane X along the gravity direction G, where the first plane X and the gravity direction G are perpendicular to each other.

[0048] In this embodiment, on the one hand, the orthogonal projection Y of the first mounting wall 1211 on the first plane X, on which the first assembly hole 1211a of the support structure 120 is installed, is located outside the orthogonal projection Z of the device body 110 on the first plane X. The first assembly hole 1211a and the device body 110 are offset in the horizontal direction H, thereby providing an operable space in the horizontal direction H for the drilling device. This has the advantage of making drilling and installation easier than when the orthogonal projection Y of the first mounting wall 1211 on the first plane X is located inside the orthogonal projection Z of the device body 110 on the first plane X. On the other hand, with this installation, after the energy storage device 100 is moved to the predetermined installation area, holes can be drilled in the ground corresponding to the positions of the first assembly holes 1211a. This improves or solves the problem of the assembly holes of the support structure 120 not matching the drilled holes in the ground during installation, which occurs when drilling holes in the predetermined installation area in advance. This further improves the assembly efficiency of the energy storage device 100.

[0049] Optionally, as shown in FIGS. 1 and 2, the first support plate 121 further includes a second mounting wall 1212 connected to the first mounting wall 1211, and the orthogonal projection P of the second mounting wall 1212 on the first plane X is located inside the orthogonal projection Z of the device body 110 on the first plane X, and the second mounting wall 1212 is provided with a second assembly hole 1212a for fixing the device body 110 to the ground.

[0050] Similarly, the orthogonal projection P of the second mounting wall 1212 on the first plane X refers to the projection of the second mounting wall 1212 on the first plane X along the gravity direction G, where the first plane X and the gravity direction G are perpendicular to each other.

[0051] In this embodiment, the first support plate 121 includes a first mounting wall 1211 whose orthogonal projection Y on the first plane X is located outside the orthogonal projection Z on the first plane X of the device body 110, and further includes a second mounting wall 1212 whose orthogonal projection P on the first plane X is located inside the orthogonal projection Z on the first plane X of the device body 110, and a second assembly hole 1212a is provided on the second mounting wall 1212. Meanwhile, when the mounting space in the horizontal direction H is insufficient, an operator can open the second assembly hole 1212a. For example, when there is a relatively high requirement for integration between the energy storage devices 100, holes may be drilled in a predetermined mounting area in advance, and then the energy storage device 100 may be moved into the predetermined mounting area to align the second assembly holes 1212a with the holes pre-drilled in the ground, and finally bolts may be inserted into the second assembly holes 1212a and the holes pre-drilled in the ground to fix the energy storage device 100 to the ground. On the other hand, when there is sufficient mounting space in the horizontal direction H, it is advantageous to mount the energy storage device 100 using both the first assembly holes 1211a and the second assembly holes 1212a, which can save mounting space and improve the stability of the energy storage device 100.

[0052] Optionally, in one embodiment, the first support plate 121 is a flat plate.

[0053] In this embodiment, the first support plate 121 is installed as a flat plate, which can save the space occupied by the first support plate 121 and also facilitate the processing of the first support plate 121. At the same time, because the first support plate 121 is a flat plate, the first mounting wall 1211 and the second mounting wall 1212 are two parts located on the same plane of the first support plate 121, which not only facilitates the drilling of assembly holes but also saves costs and ensures the efficiency of processing and assembly.

[0054] In some embodiments, the first support plate 121 may not be a flat plate. For example, the first mounting wall 1211 and the second mounting wall 1212 of the first support plate 121 may be two mounting walls having different thicknesses, i.e., the connection between the first mounting wall 1211 and the second mounting wall 1212 has a stepped structure.

[0055] Optionally, in another embodiment, the first mounting wall 1211 and the second mounting wall 1212 are integrally formed.

[0056] In this embodiment, the first mounting wall 1211 and the second mounting wall 1212 are integrally molded, which can strengthen the connection strength between the first mounting wall 1211 and the second mounting wall 1212 and improve the stability and reliability of the energy storage device 100.

[0057] Alternatively, in some other embodiments, the first mounting wall 1211 and the second mounting wall 1212 may be independent members, and the two may be connected by a method such as welding, and the embodiments of the present application are not limited thereto.

[0058] Optionally, as shown in FIG. 1, the support structure 120 further includes a fixing member 122, which protrudes in a direction away from the first support plate 121 compared to the first support plate 121, and the fixing member 122 is connected between the device body 110 and the first support plate 121.

[0059] Alternatively, one end of the fixing member 122 along the direction of gravity G of the device body 110 can be connected to the first support plate 121, and the first support plate 121 can be divided into a first mounting wall 1211 and a second mounting wall 1212, and the other end of the fixing member 122 along the direction of gravity G of the device body 110 can be connected to the device body 110, so that the orthogonal projection Y of the first mounting wall 1211 on a first plane X perpendicular to the direction of gravity G is located outside the orthogonal projection Z of the device body 110 on the first plane X, and the orthogonal projection P of the second mounting wall 1212 on the first plane X is located inside the orthogonal projection Z of the device body 110 on the first plane X.

[0060] In this embodiment, on the one hand, the fixing member 122 can connect the device body 110 and the first support plate 121, thereby enabling the support structure 120 to realize the function of supporting the device body 110; on the other hand, the fixing member 122 can raise the height of the device body 110, providing more installation space for the first support plate 121 and ensuring the reliability, stability and convenience of the installation of the energy storage device 100.

[0061] Optionally, still referring to FIG. 1, an orthogonal projection Y of the first mounting wall 1211 on a first plane X perpendicular to the direction of gravity G and an orthogonal projection P of the second mounting wall 1212 on the first plane X perpendicular to the direction of gravity G are located on either side of an orthogonal projection R of the fixing member 122 on the first plane X, respectively.

[0062] Similarly, the orthogonal projection R of the fixed member 122 on the first plane X refers to the projection of the fixed member 122 on the first plane X along the direction of gravity, where the first plane X and the direction of gravity G are perpendicular to each other.

[0063] In this embodiment, the orthogonal projections Y and P of the first mounting wall 1211 and the second mounting wall 1212 on the first plane X are located on both sides of the orthogonal projection R of the fixing member 122 on the first plane X, thereby reducing the amount of material used in the support structure 120 and thereby reducing the cost of the energy storage device 100.

[0064] Optionally, in the present embodiment, the fixing member 122 and the first support plate 121 are vertical.

[0065] Optionally, in other embodiments, the first support plate 121 may include only the first mounting wall 1211 and not the second mounting wall 1212. For example, the first support plate 121 and the fixing member 122 may have an "L" shape.

[0066] Optionally, the dimension of the first mounting wall 1211 is smaller than the dimension of the second mounting wall 1212 in the horizontal direction H, as shown in FIG.

[0067] In this embodiment, the dimension of the first mounting wall 1211 in the horizontal direction H is smaller than the dimension of the second mounting wall 1212, so that the gap between the energy storage devices 100 can be reduced as much as possible, thereby improving the integration degree of multiple energy storage devices 100.

[0068] Optionally, in the embodiment of the present application, the first mounting wall 1211 may have one or more first assembly holes 1211a. For example, the first mounting wall 1211 may have two first assembly holes 1211a. Optionally, the first assembly holes 1211a may have a "U" shape for easier mounting. However, as will be understood by those skilled in the art, the embodiment of the present application is not limited thereto. For example, the first assembly holes 1211a may be circular, elliptical, or have a special shape.

[0069] Similarly, in the present embodiment, the second mounting wall 1212 may have one or more second assembly holes 1212a. For example, the second mounting wall 1212 may have two second assembly holes 1212a. Optionally, the second assembly holes 1212a may be U-shaped for easier mounting. However, as will be understood by those skilled in the art, the present embodiment is not limited thereto. For example, the second assembly holes 1212a may be circular, elliptical, or have a special shape.

[0070] 3, a gasket 124 is installed on the bottom surface of the first support plate 121. Optionally, the material of the gasket 124 may be stainless steel.

[0071] In this embodiment, adding a gasket 124 to the bottom surface of the first support plate 121 is advantageous in reducing the probability of wear and / or rust on the bottom coating layer of the support structure 120 .

[0072] Still referring to FIG. 3, the gasket 124 and the first support plate 121 may be fixedly connected via a rivet nut 125 .

[0073] Specifically, the rivet nut 125 is drilled into the mounting hole 126 where the first support plate 121 and the gasket 124 are aligned, and the rivet nut 125 is inserted into the mounting hole 126. The end face of the rivet nut 125 is tightly pressed against the mounting hole 126 with a riveting device, and the riveting operation is carried out until the back surface of the rivet nut 125 expands and breaks.

[0074] In this embodiment, the use of rivet nuts 125 to fasten the first support plate 121 and the gasket 124 provides a reliable, low-cost connection that is easy to use; at the same time, the use of rivets to connect the gasket 124 and the first support plate 121 reduces the space occupied by the rivet process, simplifies the installation and operation process, and improves operation efficiency.

[0075] Optionally, as shown in FIGS. 1 and 2, the support structure 120 further includes a second support plate 123, in which an orthogonal projection Q of the second support plate 123 on a first plane X perpendicular to the gravity direction G is located inside an orthogonal projection Z of the device body 110 on the first plane X, and a third assembly hole 123a is provided in the second support plate 123 for fixing the device body 110 to the ground.

[0076] In this embodiment, the support structure 120 includes a first assembly hole 1211a whose orthogonal projection Y on a first plane X perpendicular to the gravity direction G is located outside the orthogonal projection Z on the first plane X of the device body 110, and further includes a third assembly hole 123a whose orthogonal projection Q on the first plane X is located inside the orthogonal projection Z on the first plane X of the device body 110, so that the drilling device can perform on-site drilling outside the device body 110, improving assembly efficiency and strengthening the fixation between the device body 110 and the ground.

[0077] Optionally, as shown in FIG. 2, the support structure 120 includes at least one pair of first support plates 121, each pair of first support plates 121 including two first support plates 121, at least one second support plate 123 is installed corresponding to each pair of first support plates 121, the two first support plates 121 in each pair of first support plates 121 are installed at a distance from each other on the bottom of the device body 110, and the second support plate 123 is installed between the two first support plates 121.

[0078] In this embodiment, the two first support plates 121 in each pair of first support plates 121 are installed at a distance from each other at the bottom of the device body 110, and the second support plate 123 is installed between the two first support plates 121, which is advantageous for the support structure 120 to uniformly provide support force to the device body 110, thereby improving the stability of the energy storage device 100.

[0079] For example, as shown in FIG. 2, the support structure 120 includes two pairs of first support plates 121, i.e., four first support plates 121, which are respectively installed close to the short sides of the bottom surface of the device body 110, and each pair of first support plates 121 is installed symmetrically with respect to a central axis parallel to the short sides of the bottom surface, and one second support plate 123 is installed between each pair of first support plates 121, i.e., the support structure 120 further includes two second support plates 123.

[0080] For illustrative purposes, the connection between the second support plate 123 and the device body 110 may refer to the first support plate 121. For example, as shown in FIG. 1, the first support plate 121 and the device body 110 are connected via a fixing member 122, and the second support plate 123 and the device body 110 are also connected via a fixing member 122. The second support plate 123 and the fixing member 122 are perpendicular to each other, and may be installed in an "L" shape.

[0081] Optionally, as shown in FIG. 2, a protective plate 130 is installed at the bottom of the device body 110 .

[0082] In this embodiment, a protective plate 130 is added to the bottom of the device body 110 to prevent the forklift arms from damaging the contact surface coating layer on the bottom of the device body 110 when the energy storage device 100 is transported by the forklift.

[0083] In some embodiments, the protective plate 130 is installed at the edge region of the bottom of the device body 110 .

[0084] In this embodiment, the protective plate 130 is installed in the edge region of the bottom of the device body 110, and the protective plate 130 does not need to completely cover the bottom of the device body 110; that is, the protective plate 130 only needs to cover the bottom of the device body 110 and the area that can be contacted by a forklift, which prevents the forklift arm from damaging the contact surface coating layer on the bottom of the device body 110 and reduces the amount of material used for the protective plate 130, thereby reducing costs.

[0085] Optionally, in some other embodiments, the material of the protective plate 130 may be urethane foam.

[0086] 1 to 3, the energy storage device 100 includes a device body 110 and a support structure 120, wherein the support structure 120 includes two pairs of first support plates 121 and two second support plates 123, each pair of first support plates 121 includes two first support plates 121, the four first support plates 121 are respectively installed adjacent to the short sides of the bottom surface of the device body 110, and each pair of two first support plates 121 are both installed symmetrically with respect to a central axis parallel to the short sides of the bottom surface. Each pair of first support plates 121 has a first mounting wall 1211 and a second mounting wall 1212. The first mounting wall 1211 has a first assembly hole 1211a for fixing the device body 110 to the ground, the second mounting wall 1212 has a second assembly hole 1212a for fixing the device body 110 to the ground, and the second support plate 123 has a hole 1211b for fixing the device body 110 to the ground. The orthogonal projection Y of the first mounting wall 1211 on the first plane X is located outside the orthogonal projection Z of the device body 110 on the first plane X, the orthogonal projection P of the second mounting wall 1212 on the first plane X is located inside the orthogonal projection Z of the device body 110 on the first plane X, and the orthogonal projection Q of the second support plate 123 on the first plane X is located inside the orthogonal projection Z of the device body 110 on the first plane X. The first support plate 121 and the device body 110 are connected via the fixing member 122. The first support plate 121 and the fixing member 122 are vertical, the second support plate 123 and the fixing member 122 are also vertical, the orthogonal projection Y of the first mounting wall 1211 on the first plane X and the orthogonal projection P of the second mounting wall 1212 on the first plane X are located on both sides of the orthogonal projection R of the fixing member 122 on the first plane X, and the dimension of the first mounting wall 1211 is smaller than the dimension of the second mounting wall in the horizontal direction H. Gaskets 124 are installed on the bottom surfaces of the first support plate 121 and the second support plate 123, and a protective plate 130 is installed on the bottom of the device body 110.

[0087] In this embodiment, the orthogonal projection Y of the first mounting wall 1211 on the first plane X, where the first assembly hole 1211a of the support structure 120 is installed, is located outside the orthogonal projection Z of the device body 110 on the first plane X. The first assembly hole 1211a and the device body 110 are offset in the horizontal direction H, which provides the drilling device with an operable space in the horizontal direction H. This improves or solves the problem of the assembly holes of the support structure 120 not matching with the drilled holes in the ground during installation, which occurs when drilling holes in a predetermined mounting area in advance, and further improves the assembly efficiency of the energy storage device 100. In addition to including a first mounting wall 1211 whose orthogonal projection Y on the first plane X is located outside the orthogonal projection Z on the first plane X of the device body 110, the device further includes a second mounting wall 1212 whose orthogonal projection P on the first plane X is located inside the orthogonal projection Z on the first plane X of the device body 110, and a second support plate 123 whose orthogonal projection Q on the first plane X is located inside the orthogonal projection Z on the first plane X of the device body 110, the second mounting wall 1212 having a second assembly hole 1212a and the second support plate 123 having a third assembly hole 123a. On the one hand, if the installation space in the horizontal direction H is insufficient, it is advantageous for workers to secure the energy storage device 100 to the ground using the second assembly hole 1212a and the third assembly hole 123a. On the other hand, if the installation space in the horizontal direction H is sufficient, it is advantageous to install the energy storage device 100 together through the first assembly hole 1211a, the second assembly hole 1212a, and the third assembly hole 123a, which can save installation space and improve the stability of the energy storage device 100. Finally, adding gaskets 124 to the bottom surfaces of the first support plate 121 and the second support plate 123 is advantageous in reducing the likelihood of wear and / or rust on the bottom coating layer of the support structure 120. In addition, adding a protective plate 130 to the bottom of the device body 110 can prevent the forklift arms from damaging the contact surface coating layer on the bottom of the device body 110 when the energy storage device 100 is transported by a forklift.

[0091] S230, inserting bolts into the first assembly holes 1211a and the drilled holes in the ground, thereby securing the energy storage device 100 to the ground.

[0092] In this embodiment, the first assembly hole 1211a and the device body 110 are offset in the horizontal direction H, so that the energy storage device 100 is first positioned in a predetermined installation area, and then holes are drilled in the ground corresponding to the first assembly hole 1211a. Finally, bolts are inserted into the first assembly hole 1211a and the drilled holes in the ground to fix the energy storage device 100 to the ground. This improves or solves the problem of the assembly holes of the support structure 120 not matching with the drilled holes in the ground during installation, which occurs when drilling holes in a predetermined installation area in advance, and further improves the assembly efficiency of the energy storage device 100.
