[0065] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0066] The following combination Figures 1 to 18 The modular distributed energy storage cabinet in the embodiments of this utility model will be described in detail.

[0067] like Figure 1 and Figure 2 As shown, the modular distributed energy storage cabinet of this utility model embodiment includes a frame body 1. The frame body 1 includes a first frame 11, a second frame 12 and a partition assembly 61. The first frame 11 and the second frame 12 are arranged side by side and connected together. The partition assembly 61 is disposed between the first frame 11 and the second frame 12 to separate the compartments of the first frame 11 and the second frame 12.

[0068] The first frame 11 and the second frame 12 define compartments of different volumes, which facilitates the separate arrangement of different equipment in the energy storage cabinet, improves practicality, and allows for free assembly of the first frame 11 and the second frame 12 of different volumes according to capacity requirements, resulting in greater production flexibility.

[0069] The modular distributed energy storage cabinet also includes two door panel assemblies 2, multiple side panel assemblies 3, a bottom plate assembly 4, and a top plate assembly 5. One of the two door panel assemblies 2 is connected to one side of the first frame 11, and the other is connected to one side of the second frame 12. The multiple side panel assemblies 3 are connected to the sides of the frame body 1 to seal the circumferential sidewalls of the frame body 1 together with the door panel assemblies 2. The bottom plate assembly 4 is connected to the bottom of the frame body 1. The top plate assembly 5 is connected to the top of the frame body 1.

[0070] The modular distributed energy storage cabinet of this utility model is divided into a frame body 1, door panel assembly 2, side panel assembly 3, bottom plate assembly 4, and top plate assembly 5, which are processed separately and then assembled. In this embodiment, the two door panel assemblies 2 are respectively installed on the first frame 11 and the second frame 12, and the compartments of the first frame 11 and the second frame 12 are independently arranged. While ensuring the overall performance of the cabinet, the equipment in each compartment can be operated independently without interference. This embodiment reduces the volume of individual components, and through the assembly and connection of multiple components, it greatly improves production efficiency and reduces processing and transportation difficulties.

[0071] like Figures 1 to 4 As shown, in some embodiments, each end face of the first frame 11 and the second frame 12 is a rectangular frame. The first frame 11 and the second frame 12 both include uprights 112, crossbars 111 and tee connectors 113. Adjacent crossbars 111 and adjacent uprights 112 and crossbars 111 are connected by tee connectors 113.

[0072] The first frame 11 and the second frame 12 of this utility model embodiment are assembled from multiple uprights 112 and multiple crossbars 111. During the assembly process, the positioning and connection between adjacent crossbars 111 and between crossbars 111 and uprights 112 are achieved through a three-way connector 113. This not only facilitates the cutting of uprights 112 and crossbars 111 and the positioning and assembly of components, but also avoids the problem of excessive deformation that occurs when directly welding.

[0073] Furthermore, the tee connector 113 is inserted into and welded to the corresponding upright 112, and to the corresponding crossbar 111. The tee connector 113 is located at each corner of the first frame 11 or the second frame 12. During assembly, the crossbar 111 and upright 112 at each corner are first inserted into and positioned with the tee connector 113, and then fixed by welding. After insertion, the positional accuracy is high, avoiding misalignment or deformation during welding. Automated welding equipment can be used for rapid welding, improving work efficiency.

[0074] The three-way connector 113 in this embodiment can have its dimensions adjusted at certain locations according to the operational requirements of automated welding equipment.

[0075] Furthermore, both the first frame 11 and the second frame 12 also include reinforcing rods 18. The reinforcing rods 18 are connected between two adjacent horizontal bars 111 and / or between two adjacent vertical bars 112. The reinforcing rods 18 are used for PACK load bearing. The position of the reinforcing rods 18 is determined by the internal support beams of the PACK. The PACK support rails are fixed to the reinforcing rods and / or other structures of the frame, and then the PACK is placed on the rails to achieve PACK load bearing. At the same time, the reinforcing rods 18 also have the advantage of increasing the overall stability of the frame.

[0076] In some embodiments, both the crossbar 111 and the upright 112 are square tubes. The cross-section of the square tube is rectangular, and it has a rectangular hole in the middle. When connected with the tee connector 113, the orientation can be better controlled, ensuring that the tee connector 113 does not rotate relative to the crossbar 111 and the upright 112 after being plugged in. When the crossbar 111 or the upright 112 is arranged with holes or other structures, the orientation and position of the holes can be ensured to be accurate, which facilitates subsequent connection with other components.

[0077] Furthermore, the frame body 1 also includes first connecting components. The adjacent uprights 112 and the horizontal bars 111 in the first frame 11 and the second frame 12 are fixedly connected by multiple first connecting components.

[0078] In other words, the uprights 112 in the first frame 11 that are close to the second frame 12 are connected to the uprights 112 in the second frame 12 that are close to the first frame 11 by a first connecting component, and the crossbars 111 in the first frame 11 that are close to the second frame 12 are connected to the crossbars 111 in the second frame 12 that are close to the first frame 11 by a first connecting component.

[0079] The first connecting component includes a bolt 13 and a rivet nut 14. For example, between adjacent uprights 112, a rivet nut 14 is provided in one upright 112, and a bolt 13 is arranged in the other upright 112. The fixed connection between the two uprights 112 is achieved by the cooperation of the bolt 13 and the rivet nut 14.

[0080] Optionally, depending on the length of the uprights 112 and the crossbars 111, multiple first connecting components can be arranged between adjacent uprights 112 and between adjacent crossbars 111. For example, 3 to 8 first connecting components can be arranged between adjacent uprights 112 and 2 to 5 first connecting components can be arranged between adjacent crossbars 111.

[0081] Furthermore, the modular distributed energy storage cabinet also includes crossbeams 62. Multiple crossbeams 62 are provided at the top and bottom of the frame body 1, and the crossbeams 62 are connected and fixed to the frame body 1 by connectors.

[0082] The top and bottom of the first frame 11 and the second frame 12 are fixedly connected to the crossbeams 62 by connectors. There are two crossbeams 62 at the top of the frame body 1 and two crossbeams 62 at the bottom of the frame body 1. The connectors are bolts 13.

[0083] This embodiment of the utility model improves the stability of the structure by setting crossbeams 62 at both the top and bottom of the frame body 1. During the overall hoisting process, it can also ensure the stability of the cabinet and avoid deformation.

[0084] In some embodiments, the tee connector 113 includes a body 15 and three connectors 16 disposed on the body 15, the extension directions of the three connectors 16 being orthogonal to each other.

[0085] It should be understood that the tee connector 113 is located at the end corner of the first frame 11 or the second frame 12. There are 8 tee connectors 113, and the three connectors 16 of each tee connector 113 are respectively connected to two crossbars 111 and one upright 112.

[0086] Furthermore, there is a stepped surface between the connector 16 and the body 15. When the connector 16 is inserted into the inner cavity of the upright 112 or the crossbar 111, the outer wall surface of the body 15 is flush with the outer wall surface of the upright 112 or the crossbar 111.

[0087] When the upright 112 and the horizontal bar 111 are square tubes, the cross section of the plug connector 16 is rectangular.

[0088] In some embodiments, the modular distributed energy storage cabinet further includes a lifting ring 19, and a first connection hole 17 is provided on the three-way plug-in member 113 located at the top of the first frame 11 and the second frame 12, and the lifting ring 19 is connected in the first connection hole 17.

[0089] A screw is provided at the bottom of the lifting ring 19, and the first connecting hole 17 is a threaded hole. The screw at the bottom of the lifting ring 19 is connected in the first connecting hole 17. During hoisting, the hoisting force can be distributed to the horizontal bar 111 and the vertical bar 112 through the three-way connector 113. This avoids excessive local stress and deformation when directly hoisting the horizontal bar 111, and also avoids reducing the structural strength after directly drilling holes in the horizontal bar 111.

[0090] In some embodiments, the first frame 11 has a first compartment, the second frame 12 has a second compartment, and the first and second compartments are arranged side by side in a first direction.

[0091] The first and second directions are the left and right directions shown in the figure.

[0092] In this embodiment of the invention, the first compartment serves as the battery pack compartment, and the second compartment serves as the power distribution compartment.

[0093] Furthermore, the volume of the first compartment in this embodiment of the invention is determined based on the battery PACK, power distribution PCS, and water-cooled unit arranged inside. Since the projected areas of the first compartment and the second compartment on the plane perpendicular to the first direction are the same, the capacity of the first compartment can be increased by adjusting the length of the first compartment in the first direction.

[0094] In addition to adjusting the size of the first compartment according to the size of the installed PACK, when there is a new requirement for the capacity of the energy storage cabinet, it can also be achieved by adding one or more battery PACK compartments. No redesign is required; simply increasing the number of battery PACK compartments is sufficient for quick implementation.

[0095] like Figure 5 As shown, in some embodiments, the side panel assembly 3 includes an inner panel 31, an outer panel 32, and a filling layer 33. The inner panel 31 and the outer panel 32 are parallel and spaced apart along their thickness direction; the filling layer 33 is disposed between the inner panel 31 and the outer panel 32.

[0096] The outer wall surface of the inner plate 31 is a flat end face, the outer wall surface of the outer plate 32 has an outwardly folded boss, and the outer plate 32 is provided with reinforcing ribs.

[0097] The inner panel 31 serves as the wall of the compartment, the outer panel 32 serves as the outer shell of the cabinet, and the filling layer 33 serves as an insulation or fireproof layer. To improve structural strength, the outer panel 32 can be folded outward to form a convex structure, or reinforcing ribs can be welded onto the outer panel 32 to strengthen the structure of the outer shell. The filling layer 33 is cut to the required dimensions and arranged between the outer panel 32 and the inner panel 31.

[0098] Optionally, in this embodiment of the present invention, the filling layer 33 is a thermal insulation rock wool board.

[0099] Furthermore, the inner panel 31 and the outer panel 32 are fixedly connected in the circumferential direction by connectors. The inner panel 31 is provided with a folded edge that folds towards the outer panel 32 in the circumferential direction. After the folded edge abuts against the outer panel 32, it is connected and fixed together by connectors such as bolts 13 and rivets, which can seal the filling layer 33, so that the side panel assembly 3 forms a relatively stable component, which facilitates subsequent assembly.

[0100] Furthermore, the side panel assembly 3 is fixedly connected to the corresponding first frame 11 or second frame 12 via connectors.

[0101] Optionally, the inner plate 31 and the filling layer 33 form an outwardly protruding structure on the outer plate 32. The outer plate 32 has a certain width of circumferential assembly part for assembly connection. During the assembly process, the circumferential assembly part of the outer plate 32 abuts against the first frame 11 or the second frame 12, and then is connected and fixed together by bolts 13 and other connecting parts.

[0102] Furthermore, the partition plate assembly 61, the bottom plate assembly 4, and the top plate assembly 5 all include an inner plate 31, an outer plate 32, and a filling layer 33. In other words, the structure of the partition plate assembly 61, the bottom plate assembly 4, and the top plate assembly 5 is the same as that of the side plate assembly 3. This ensures that the sealing performance, structural strength, and thermal insulation performance of each end face of the cabinet are relatively consistent, resulting in better stability.

[0103] like Figures 7 to 10 As shown, in some embodiments, the two door panel assemblies 2 are located on the same side of the frame body 1, and the number of side panel assemblies 3 arranged opposite to the two door panel assemblies 2 is two, namely the first rear side panel assembly 34 and the second rear side panel assembly 35. The first rear side panel assembly 34 is fixedly connected to the first frame 11, and the side of the second rear side panel assembly 35 closest to the first frame 11 is provided with a hook 351, which is hung on the first rear side panel assembly 34. The other sides of the second rear side panel assembly 35 are fixedly connected to the second frame 12.

[0104] It should be understood that since the main frame 1 is assembled from the first frame 11 and the second frame 12, the side panel assembly 3 on the side opposite to the two door panel assemblies 2 can be set as an integral structure or designed as a separate structure. When designed as an integral structure, it is easy to reduce its versatility. When the size of the first frame 11 or the second frame 12 changes, the side panel assembly 3 of the integral structure cannot be used.

[0105] In this embodiment of the utility model, the side panel assembly 3, which is arranged opposite to the two door panel assemblies 2, is configured as two separate parts, namely a first rear side panel assembly 34 and a second rear side panel assembly 35. In order to facilitate the connection and fastening operation between the components, a hook 351 is provided on the second rear side panel assembly 35, and a hanging hole 341 is provided on the first rear side panel assembly 34. During assembly, the first rear side panel assembly 34 is first fixed on the first frame 11, and then the hook 351 on the second rear side panel assembly 35 is hung in the hanging hole 341 to achieve positioning and connection. No other connecting parts are required between the second rear side panel assembly 35 and the first rear side panel assembly 34. Finally, the other sides of the second rear side panel assembly 35 are fixedly connected to the second frame 12 by bolts 13 and other connecting parts.

[0106] Alternatively, the second side panel assembly 3 can be replaced with a rear door assembly.

[0107] like Figure 1 and 14 As shown, in some embodiments, the modular distributed energy storage cabinet also includes two door frame assemblies 21, which are respectively connected to the first frame 11 and the second frame 12, and two door panel assemblies 2 are respectively connected to the two door frame assemblies 21.

[0108] To facilitate the assembly of the door panel assembly 2, door frame assemblies 21 are respectively provided on the first frame 11 and the second frame 12. The door frame assembly 21 is welded together, for example, by welding two uprights and two horizontal bars to form a rectangular frame. The door frame assembly 21 is welded and fixed to the corresponding first frame 11 or second frame 12, or connected and fixed by bolts 13 and other connecting parts.

[0109] The door panel assembly 2 is installed on the corresponding door frame assembly 21, making the assembly between the components more stable.

[0110] like Figures 11 to 13As shown, in some embodiments, the modular distributed energy storage cabinet also includes a corner assembly 7. The corner assembly 7 is located at the circumferential corner of the frame body 1. The corner assembly 7 includes an arc plate 71, an inner support plate 72, a buckle 73, and a mounting buckle 74. The arc plate 71 has an arc-shaped outer wall surface. Multiple inner support plates 72 are spaced apart on the side of the arc plate 71 near the frame body 1. The buckle 73 is connected to the inner support plate 72, and the mounting buckle 74 is connected to the frame body 1. The buckle 73 and the mounting buckle 74 are snapped together.

[0111] This embodiment of the utility model provides a corner component 7 at the corner between two adjacent sides of the cabinet, which allows for a smooth transition of the rounded corner, improves the overall aesthetics of the cabinet, and fills the gap between adjacent side panel components 3.

[0112] The inner support plate 72 is arranged on the inner side of the arc plate 71. Multiple inner support plates 72 are spaced apart along the length of the arc plate 71, which can increase the structural strength of the arc plate 71 and prevent the arc plate 71 from deforming. At the same time, it can provide basic support for the arrangement of the buckle 73. In this embodiment of the utility model, the mounting buckle 74 is provided on the frame body 1, and the buckle 73 is set on the inner support plate 72. The buckle 73 and the mounting buckle 74 are arranged in a one-to-one correspondence. After the side plate components 3 are installed, the arc plate 71 is fixed to the frame body 1 by pressing.

[0113] The curved plate 71 has folded edges on both sides in the width direction and both sides in the length direction, which can improve strength, avoid local deformation, and ensure structural stability.

[0114] like Figure 1 and Figure 15 As shown, in some embodiments, the modular distributed energy storage cabinet also includes a top cover assembly 8, which is fixed to the top of the frame body 1. The top cover assembly 8 includes a top cover plate 81 and a side baffle 82 disposed on the circumferential downward side of the top cover plate 81.

[0115] In this embodiment of the utility model, the top cover assembly 8 is installed on the top of the cabinet, which improves the overall performance of the cabinet. The side baffle 82 of the top cover assembly 8 can wrap around the outside of a section of the side panel assembly 3, or it can be flush with the top of the side panel assembly 3, thereby avoiding the exposure of the connecting parts between the side panel assembly 3 and the frame body 1, forming a hidden design, and also making the assembled product structure more beautiful and elegant.

[0116] like Figure 1 , Figure 16 and Figure 17As shown, in some embodiments, the modular distributed energy storage cabinet also includes a enclosure component 9. The enclosure component 9 is located circumferentially at the bottom of the frame body 1. The enclosure component 9 includes multiple enclosure panels 91. The frame body 1 is provided with a fixed bracket 92. The enclosure panels 91 are fixed to the corresponding fixed brackets 92 by connectors.

[0117] To ensure the rack can be forked, the enclosure assembly 9 involves disassembly. Therefore, in this embodiment of the invention, multiple enclosure panels 91 can be disassembled independently to meet forklift requirements. The enclosure is fixed to the fixing bracket 92 on the frame body 1 by bolts 13. The fixing bracket 92 can be welded to the frame body 1.

[0118] like Figure 1 and Figure 18 As shown, in some embodiments, the top plate assembly 5 has a waterfall outlet 51, the inner wall of the waterfall outlet 51 is provided with an inner baffle 52, the top of the waterfall outlet 51 is provided with a waterfall plate 53 and a pressure plate 54, the pressure plate 54 is fixed to the top plate assembly 5, the waterfall plate 53 is located between the pressure plate 54 and the top plate assembly 5, the pressure plate 54 and the waterfall plate 53 are circumferentially corresponding and abut against each other, and the waterfall plate 53 has a weak area.

[0119] The inner baffle is located on the inner wall of the waterfall outlet, forming a flow channel. The waterfall plate is fixed to the top plate assembly by pressure plate and bolts. The pressure plate is used to press and fix the waterfall plate in the circumferential direction and ensure that the circumferential force of the waterfall plate is relatively stable.

[0120] During operation, after a fire occurs and water is injected, the weak points in the first compartment can rupture under pressure, allowing the water to break through the riprap and drain to the outside, and then enter the power distribution compartment (second compartment) to protect the electrical components inside the power distribution compartment.

[0121] Optionally, the weak area is the annular or rectangular edge groove around the waterfall plate 53. When water is injected, the waterfall plate 53 is more likely to crack at the edge groove, which in turn causes the plate in the middle of the edge groove to fall off.
