Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to a beam, a container, and an energy storage device. Background Technology

[0002] As energy storage technology develops towards larger capacity and larger scale, the industry has begun to adopt containerized battery assembly. Among them, the container, which is roughly rectangular in shape and has a large internal space, can store a sufficient number of batteries, and has thus gained favor in the industry.

[0003] Containers typically consist of beams, columns, side panels, doors, and other structural components. The beams at the bottom of the container provide the main support and bear the majority of the pressure. Containers fully loaded with batteries often weigh tens of tons, and under such significant pressure, the beams are prone to insufficient strength and rigidity, leading to deformation, bending, and other issues, resulting in compromised reliability.

[0004] Currently, the crossbeams are mainly made of square tubing or channel steel. Due to the need to meet reliability requirements, the industry often adopts a solution with thicker steel, which brings a greater weight to the container. In addition, the operating environment temperature of containers for energy storage equipment is usually -40℃ to 55℃. At an ambient temperature of around -40℃, in order to ensure the structural strength of the container, there are special requirements for the thicker steel, which will result in higher costs. Utility Model Content

When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0041] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0042] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Please refer to Figures 1 to 3 This utility model embodiment provides a container 100, including the crossbeam 10 in this utility model embodiment, as well as longitudinal beams 21, floor 22, columns 31, side panels 32, doors 33, ceiling 34, connecting beams 35, etc.

[0044] The crossbeam 10, longitudinal beam 21, and floor 22 are located at the bottom of the container 100. The crossbeam 10 is connected to the longitudinal beam 21, and the length directions of the crossbeam 10 and the longitudinal beam 21 are approximately perpendicular. The length direction of the crossbeam 10 is the length direction of the container 100, and the length direction of the longitudinal beam 21 is the width direction of the container 100. The floor 22 is connected to the crossbeam 10 and the longitudinal beam 21. Together, they support the battery device (not shown) housed inside the container 100, as well as the structure of the container 100 itself above the columns 31.

[0045] The crossbeams 10 can be two opposite beams extending from one end of the container 100 along its length to the other. The longitudinal beams 21 can be multiple beams, spaced apart along the length of the container 100, with one longitudinal beam 21 at each end of the container 100 and another in the middle region along its length. The length of the crossbeams 10 is greater than the length of the longitudinal beams 21; the length of the crossbeams 10 is approximately the length of the container 100, and the length of the longitudinal beams 21 is approximately the width of the container 100. Since there are only two crossbeams 10, which are longer than the longitudinal beams 21, each crossbeam 10 bears greater pressure. Therefore, this embodiment of the invention features a unique design for the crossbeams 10. Because the longitudinal beams 21 are shorter and more numerous, each longitudinal beam 21 bears relatively less pressure and can be made of steel with a conventional thickness.

[0046] One end of the upright 31 is connected to the crossbeam 10 or the longitudinal beam 21, and the other end is connected to the connecting beam 35 located at the top of the container 100. The length direction of the upright 31 is the height direction of the crossbeam 10. The side panel 32 and the door 33 are located in the middle of the container 100, and the ceiling 34 is located at the top of the container 100 and connected to the connecting beam 35. There are multiple uprights 31, which are evenly spaced. The side panel 32 is connected to the crossbeam 10, the upright 31, and the connecting beam 35, and the door 33 is connected to the upright 31 in an openable and closable manner.

[0047] Optionally, connecting blocks 23 can be installed at the four corners of the bottom of the container 100. The crossbeam 10, the uprights 31, and the outermost longitudinal beam 21 are all connected to the connecting blocks 23. The connecting blocks 23 have a mating structure that adapts to the crossbeam 10, the longitudinal beam 21, and the uprights 31. The mating structure, such as holes, slots, steps, etc., is not limited. By setting the connecting blocks 23, the assembly of the crossbeam 10, the longitudinal beam 21, and the uprights 31 can be easily carried out.

[0048] Optionally, a buffer pad 24 can be provided at the bottom of the crossbeam 10. The buffer pad 24 can be a single strip or multiple spaced squares. The buffer pad 24 can be used to contact the ground or other supporting surfaces. The buffer pad 24 can absorb the uneven structure of the supporting surface, so that the bottom of the crossbeam 10 is evenly stressed and avoids being bent or deformed by the uneven supporting surface.

[0049] Container 100 may also have other structures, which will not be elaborated here; please refer to the relevant technical documents for details.

[0050] Please refer to Figure 3 and Figure 4 The crossbeam 10 for the container 100 in this embodiment of the present invention adopts a unique structural design. Specifically, the crossbeam 10 includes a beam body 11 and a reinforcing plate 12. The beam body 11 encloses an installation space 111, and the reinforcing plate 12 is housed in the installation space 111 and connected to the beam body 11 at at least two opposite positions.

[0051] The specific structure of the beam 11 and the reinforcing plate 12 is not limited, and both can be made of steel plates. When the reinforcing plate 12 is connected to the beam 11, welding, riveting, screwing, snap-fitting, etc., are not limited. The installation space 111 can be open at both ends or at one end along the length of the beam 11. The reinforcing plate 12 can extend into the installation space 111 through the open end of the beam 11 and connect to the inner wall of the installation space 111. The connection of the reinforcing plate 12 to at least two opposite positions of the beam 11 means that the beam 11 has opposite sides, and the reinforcing plate 12 is connected to at least one position on one side of the beam 11 and to at least one position on the opposite side. Specifically, the reinforcing plate 12 is connected to at least one position on one side of the inner wall of the installation space 111 and to at least one position on the opposite side of the inner wall of the installation space 111. This allows the reinforcing plate 12 to provide support at least two positions of the beam 11 to which it is connected, thereby strengthening the structural strength and rigidity of the beam 10.

[0052] Optionally, the reinforcing plate 12 includes at least one of flat steel, angle steel, channel steel, I-beam, H-beam, T-beam, etc. Figure 7 and Figure 8 Taking a channel steel as an example, the reinforcing plate 12 shown includes a web 121 and two flanges 122 connected to the web 121. These two flanges 122 are connected to the beam 11 by welding or other means. At one location along the length of the beam 10, each flange 122 may have one or more weld points to the beam 11. When there is one weld point, the reinforcing plate 12 is connected to one location on one side of the beam 11. When there are multiple weld points, the multiple weld points are spaced apart along the thickness direction of the web 121, and the reinforcing plate 12 is connected to multiple locations on one side of the beam 11. It can be understood that along the length direction of the web 121, each flange 122 has multiple weld points spaced apart from the beam 11. Figure 9Taking the reinforcing plate 12 as an example of flat steel, at one position along the length of the beam 10, both ends of the flat steel in the width direction have a weld point to the beam 11, so that the reinforcing plate 12 has a connection point on each of the opposite sides of the beam 11. It can be understood that, along the length of the flat steel, both ends in the width direction have multiple weld points spaced apart from the beam 11. It can also be understood that these weld points can be continuous welds. These weld points and continuous welds are the connection points between the reinforcing plate 12 and the inner wall of the installation space 111. Other possible embodiments of the reinforcing plate 12 will not be elaborated upon; it is sufficient that the reinforcing plate 12 provides connection points to the opposite sides of the beam 11 and serves a supporting and reinforcing function.

[0053] Optionally, the installation space 111 is not open in any other direction perpendicular to the length direction of the beam 11; that is, the installation space 111 communicates with the outside only at the end opening in the length direction of the beam 11. For example, the cross-section of the beam 11 can be circular, rectangular, etc., that is, the beam 11 can be approximately circular (see reference). Figure 9 ), Fangtong (reference) Figure 8 Alternatively, the installation space 111 may also be open in at least one other direction perpendicular to the length direction. That is, in addition to communicating with the outside at the end opening in the length direction of the beam 11, the installation space 111 may also be open in other directions. For example, the cross-section of the beam 11 may be C-shaped, I-shaped, etc., that is, the beam 11 may be approximately channel steel, I-beam, etc. The reinforcing plate 12 may extend into the installation space 111 through the end opening in the length direction of the beam 11, or through the open portion.

[0054] The reinforcing plate 12 is connected to at least two opposite positions of the beam 11, so that the reinforcing plate 12 can support the beam 11 at these at least two opposite positions. That is, when the beam 11 is subjected to pressure at these at least two opposite positions, it will not move relative to each other and be bent or deformed, thereby improving the structural strength and stiffness of the beam 11 in the direction of the opposite position connected to the reinforcing plate 12.

[0055] When the crossbeam 10 is applied to the container 100, at least two locations where the reinforcing plate 12 connects to the beam 11 are opposite each other in the height direction of the container 100. The crossbeam 10, longitudinal beams 21, floor 22, etc. at the bottom of the container 100 bear the weight of the container 100 itself and the weight of the battery devices inside the container 100. For the crossbeam 10, it mainly bears the pressure from the height direction of the container 100. Therefore, the beam 11 is easily bent or deformed in the height direction of the container 100. After the reinforcing plate 12 is installed, the reinforcing plate 12 can improve the structural strength and stiffness of the beam 11 in the height direction of the container 100, thereby enabling the crossbeam 10 to meet the reliability requirements.

[0056] Currently, conventional crossbeams mainly use square tubing, channel steel, and I-beams. To meet reliability requirements, they need to be relatively thick, which results in a heavier hull for the container 100. The operating environment temperature for containers used in energy storage equipment is typically -40℃ to 55℃. At temperatures around -40℃, special processing is required for thicker steel to ensure the structural strength of the container, leading to higher costs. Compared to mainstream crossbeams, the beam body 11 in the crossbeam 10 of this embodiment is similar to mainstream crossbeams, but without the need for thickening. Instead, a reinforcing plate 12 is installed within the beam body 11 to address reliability issues. Compared to thickening the crossbeam, this invention uses a beam body 11 of conventional thickness. The total weight of the beam body 11 and the reinforcing plate 12 is lower than that of a thickened crossbeam, resulting in a smaller increase in the hull weight of the container 100 compared to using a thickened crossbeam 10.

[0057] The container 100 of this utility model adopts a unique design of crossbeam 10, in which a reinforcing plate 12 is set inside the beam body 11 of the crossbeam 10. The reinforcing plate 12 is connected to the beam body 11 at at least two positions opposite to the beam body 11, thereby improving the structural strength and rigidity of the crossbeam 10. Both the beam body 11 and the reinforcing plate 12 can be made of steel of conventional thickness to meet the reliability requirements, reducing the added weight of the container 100 and avoiding the high cost caused by the special treatment required for thicker steel.

[0058] Furthermore, if a conventional crossbeam deviates from its connection to the longitudinal beam, for example, if the crossbeam rotates at a certain angle around its length, resulting in one end being higher than the other, it will affect the structural strength and stiffness, potentially leading to compromised mechanical properties. However, in this embodiment of the invention, the crossbeam 10 has a reinforcing plate 12 inside the beam body 11, which can improve the problem of compromised mechanical properties caused by connection deviations in the crossbeam 10. Due to the presence of the reinforcing plate 12, even if the crossbeam 10 deviates, it can still meet reliability requirements and improve fault tolerance.

[0059] Furthermore, in conventional beam structures made of channel steel, square tubing, etc., corrosion of the web plate bearing pressure can exacerbate the corrosion and potentially cause structural damage, leading to beam bending and deformation. In contrast, the reinforcing plate 12 of this embodiment is located within the installation space 111 of the beam body 11, making it less susceptible to corrosion. The reinforcing plate 12 divides the interior of the beam body 11 into multiple sections, effectively supporting the weight and increasing the overall pressure-bearing capacity of the beam 10. Even if the web plate 121 of the beam body 11 experiences some corrosion, the overall reliability of the beam 10 can still be guaranteed.

[0060] refer to Figure 5The beam 11 has a length of L1, and the reinforcing plate 12 has a length of L2, satisfying: 0.8 ≤ L2 / L1 ≤ 1.1. Setting the lengths of the beam 11 and the reinforcing plate 12 to be relatively close allows the reinforcing plate 12 to strengthen the beam 11 at all points along its length, thus ensuring that the strength and stiffness of the beam 10 at all points along its length meet reliability requirements. The specific values ​​of L1 and L2 are not limited, and the specific value of L2 / L1 can be 0.8, 0.85, 0.8, 0.95, 1.0, 1.05, 1.1, etc.

[0061] When 0.8 ≤ L2 / L1 < 1, the length of the reinforcing plate 12 is slightly less than the length of the beam 11. Most of the beam 11's length is reinforced by the reinforcing plate 12, with only a small percentage of the area remaining unreinforced. For example, even if there is no reinforcing plate 12 near the end of the beam 11's length, the overall reliability of the beam 10 can still be improved because the bottom of the crossbeam 10 can contact the supporting surface through the buffer pad 24, and the middle area of ​​the crossbeam 10 is also connected to the longitudinal beam 21, which also bears pressure. Therefore, even in a small local area of ​​the beam 11 where the reinforcing plate 12 is absent, the overall reliability of the crossbeam 10 can still be improved.

[0062] When 1.0 < L2 / L1 ≤ 1.1, the reinforcing plate 12 strengthens all positions of the crossbeam 10. The reinforcing plate 12 is longer than the beam 11, so that the reinforcing plate 12 can extend a small section outside the beam 11 and can be used to connect with the longitudinal beam 21, column 31, etc., making the connection easier.

[0063] If L2 / L1 < 0.8, the reinforcing plate 12 is too short, and the proportion of local areas of the beam 11 without the reinforcement of the reinforcing plate 12 is too large, resulting in insufficient strength and stiffness of the crossbeam 10 in that local area, which cannot meet the reliability requirements.

[0064] If L2 / L1 > 1.1, the reinforcing plate 12 extends too far beyond the beam 11, adding a significant amount of weight to the container 100, which may interfere with other structures and affect pedestrian safety.

[0065] In one embodiment, reference Figure 7 The wall thickness of beam 11 is H1, and the thickness of reinforcing plate 12 is H2, satisfying H1≤8mm and / or H2≤8mm.

[0066] Conventional crossbeams lack reinforcing plates, requiring a thickness greater than 8mm to meet reliability requirements, which results in significant weight. Furthermore, steel thicker than 8mm demands special processing; for example, when welded to longitudinal beams or columns, thicker steel requires preheating, post-weld heat treatment, and defect detection, increasing costs.

[0067] In this embodiment, the beam 11 can be formed by processes such as bending, stamping, and forging of steel plates. The wall thickness of the beam 11 is the distance between corresponding positions on the inner wall of the installation space 111 and the outer surface of the beam 11, which is approximately the thickness of the steel plate. The reinforcing plate 12 is similar to the beam 11 and can also be formed by processes such as bending, stamping, and forging of steel plates. The thickness of the reinforcing plate 12 is the distance between corresponding positions on two opposing surfaces of the reinforcing plate 12, which is also approximately the thickness of the steel plate. The wall thickness of the beam 11 can be approximately equal at all points, and the wall thickness of the reinforcing plate 12 can also be approximately equal at all points.

[0068] Setting H1 ≤ 8mm allows for a thinner wall thickness in beam 11, eliminating the need for special treatments required for thicker steel plates and reducing costs. Setting H2 ≤ 8mm also allows for a thinner reinforcing plate 12, eliminating the need for special treatments required for thicker steel plates and further reducing costs. Specific values ​​for H1 and H2 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm. Optionally, setting H1 ≤ 6mm further reduces the wall thickness of beam 11, further reducing its weight, while also eliminating the need for special treatments and further reducing costs. Optionally, setting H2 ≤ 6mm further reduces the thickness of reinforcing plate 12, further reducing its weight, while also eliminating the need for special treatments and further reducing costs.

[0069] In one embodiment, reference Figures 4 to 7 The beam 11 includes a bottom plate 112, a top plate 113, and a first connecting plate 114. The bottom plate 112 and the top plate 113 are spaced apart relative to each other in the first direction Z, and the first connecting plate 114 connects the bottom plate 112 and the top plate 113. A reinforcing plate 12 connects the bottom plate 112 and the top plate 113, and the reinforcing plate 12 and the first connecting plate 114 are spaced apart in the second direction Y, where the first direction Z intersects the second direction Y.

[0070] Combination Figure 1 and Figure 7 When the crossbeam 10 is applied to the container 100, the first direction Z is the height direction of the container 100. The bottom plate 112 and the top plate 113 are approximately parallel, and the first connecting plate 114 is approximately perpendicular to the bottom plate 112 and the top plate 113. The bottom plate 112, the top plate 113, and the first connecting plate 114 are all approximately flat. The connection between the bottom plate 112 and the first connecting plate 114 can be smoothly transitioned, and the connection between the top plate 113 and the first connecting plate 114 can also be smoothly transitioned. The bottom plate 112, the top plate 113, and the first connecting plate 114 can be at least two integral structures manufactured by processes such as bending, stamping, and forging, or all three can be separate structures connected to form a whole by means such as welding. The thickness of the bottom plate 112, the top plate 113, and the first connecting plate 114 is approximately equal.

[0071] When the beam 11 only has the aforementioned bottom plate 112, top plate 113, and first connecting plate 114, and the first connecting plate 114 is located on the same side edge of the bottom plate 112 and top plate 113, the beam 11 is a channel steel. Figure 7 Taking the example where both beam 11 and reinforcing plate 12 are channel steel, the first connecting plate 114 of beam 11 is the web 121 of the channel steel, and the bottom plate 112 and top plate 113 are the two flanges 122 of the channel steel, respectively. The width of the bottom plate 112 and top plate 113, that is, the dimension in the second direction Y, is larger than the corresponding two flanges 122 of the channel steel of reinforcing plate 12. The "]"-shaped opening of the channel steel of beam 11 is opposite in direction to the "]"-shaped opening of the channel steel of reinforcing plate 12. Figure 1 and Figure 7 When the crossbeam 10 is applied to the container 100, the "]"-shaped opening of the channel steel of the beam body 11 faces the interior of the container 100. It is understood that the first connecting plate 114 can also be connected to the middle of the bottom plate 112 and the top plate 113 to form an I-beam. The reinforcing plate 12 can be provided on either side of the first connecting plate 114 in the second direction Y, or both sides can have reinforcing plates 12. The beam body 11 described above has a simple structure, is easy to manufacture, and facilitates the connection between the reinforcing plates 12 and the beam body 11.

[0072] In another embodiment, reference Figure 8 ,and Figure 7 The embodiments shown are basically the same, except that the beam 11 also includes a second connecting plate 115. The second connecting plate 115 connects the bottom plate 112 and the top plate 113, and the reinforcing plate 12 is located between the first connecting plate 114 and the second connecting plate 115, and the reinforcing plate 12 and the second connecting plate 115 are spaced apart.

[0073] Optionally, the second connecting plate 115 is also generally flat and perpendicular to the bottom plate 112 and the top plate 113. When the first connecting plate 114 is connected to the same edge of the bottom plate 112 and the top plate 113, and the second connecting plate 115 is connected to the other edge of the bottom plate 112 and the top plate 113, the beam 11 is a square tube. Alternatively, the second connecting plate 115 may not be perpendicular to the bottom plate 112 and the top plate 113 but may have an inclined angle, so that the beam 11 is trapezoidal in its orthographic projection along its length. The thickness of the second connecting plate 115 may be equal to that of the bottom plate 112, the top plate 113, and the first connecting plate 114.

[0074] Optional, see reference Figure 7 and combined Figure 8The width of the top plate 113 is smaller than the width of the bottom plate 112. One end of the second connecting plate 115 is connected to the edge of the top plate 113, and the other end of the second connecting plate 115 is connected to the surface of the bottom plate 112 facing the top plate 113. That is, the second connecting plate 115 is not connected to the edge of the bottom plate 112. The edge of the bottom plate 112 away from the first connecting plate 114 is located on the side of the second connecting plate 115 facing away from the first connecting plate 114. Figure 2 , Figure 3 , Figure 7 and Figure 8 The edge of the bottom plate 112 located outside the second connecting plate 115 can be used for welding to the floor 22 of the container 100.

[0075] Optionally, at least two of the base plate 112, top plate 113, first connecting plate 114, and second connecting plate 115 are integral structures. Figure 8 Taking the beam 11 shown as a square tube as an example, the base plate 112 and the first connecting plate 114 can be an integral structure, and the top plate 113 and the second connecting plate 115 can be an integral structure, and then the two integral structures are welded together, that is, two angle steels are welded to form a square tube; or, the base plate 112, the first connecting plate 114, and the top plate 113 can be an integral structure, and then welded to the second connecting plate 115, that is, channel steel and flat steel are welded to form a square tube; or, the first connecting plate 114 can be an integral structure with half of the base plate 112 and half of the top plate 113, and the second connecting plate 115 can be an integral structure with the other half of the base plate 112 and the other half of the top plate 113, and then welded together, that is, two channel steels are welded to form a square tube. Of course, there are other possible methods. By setting at least part of it to be an integral structure, the number of parts can be reduced and the structural strength can be increased.

[0076] In one embodiment, reference Figure 7 and Figure 8 Multiple reinforcing plates 12 are provided, spaced apart in the second direction Y. Each reinforcing plate 12 provides support and reinforcement to the beam 11, further improving the reliability of the crossbeam 10. The number of reinforcing plates 12 can be 2, 3, 4, 5, 6, etc. Figure 7 and Figure 8 An embodiment is shown with three reinforcing plates 12.

[0077] Optionally, multiple reinforcing plates 12 are arranged at equal intervals. Figure 7 and Figure 8Taking a channel steel as an example, the reinforcing plate 12 shown is arranged at equal intervals, meaning that the webs 121 of multiple reinforcing plates 12 are arranged at equal intervals, and the "]"-shaped openings are in the same direction. The equally spaced reinforcing plates 12 can evenly distribute the pressure, improving the reliability of the crossbeam 10. Further optionally, the multiple reinforcing plates 12 and the first connecting plate 114 are arranged at equal intervals. Further optionally, in embodiments with a second connecting plate 115, the multiple reinforcing plates 12, the first connecting plate 114, and the second connecting plate 115 are arranged at equal intervals. This further evenly distributes the pressure and improves reliability.

[0078] Optionally, the multiple reinforcing plates 12 may have the same thickness. Having multiple reinforcing plates 12 with identical specifications and thickness facilitates mass production and installation, eliminating the need to consider the installation sequence of different reinforcing plates 12 and reducing costs. Further, optionally, the multiple reinforcing plates 12 may have the same thickness as the beam 11. This allows the beam 11 and multiple reinforcing plates 12 to be manufactured using steel of the same thickness, further reducing costs.

[0079] In one embodiment, reference Figures 3 to 6 The bottom plate 112, the first connecting plate 114 and the reinforcing plate 12 are all provided with notches 102 near the bottom plate 112 in the length direction, so that at least one end of the crossbeam 10 in the length direction forms an installation groove 101.

[0080] The inner wall of the mounting groove 101 comprises at least a portion of the bottom plate 112, at least a portion of the first connecting plate 114, and at least a portion of the reinforcing plate 12. When there are multiple reinforcing plates 12, each reinforcing plate 12 has a notch 102. The mounting groove 101 extends from the bottom plate 112 towards the top plate 113 and inwards from the end face of the crossbeam 10 along its length, but does not penetrate the top plate 113. The mounting groove 101 is used to mate with the aforementioned connecting block 23, which can extend into the mounting groove 101 for easy positioning. This facilitates accurate assembly of the crossbeam 10 with the longitudinal beam 21, improving the assembly efficiency of the container 100.

[0081] refer to Figures 1 to 9 This utility model embodiment also provides an energy storage device, including a battery device (not shown) and a container 100 provided in this utility model embodiment, wherein the battery device is housed within the container 100. The battery device may include several battery packs and may also include various electronic control components, without limitation. Furthermore, the energy storage device can be applied to new energy power plants, such as photovoltaic power plants and wind power plants, and can also be applied to various industrial and commercial scenarios with large energy storage needs, without limitation.

[0082] The energy storage device of this utility model uses a specially designed crossbeam 10 in its container 100, which can reduce the increase of the container 100's self-weight and avoid the problem of high cost caused by the need for special treatment of thicker steel.
