Description

Technical Field

[0001] This application relates to the field of energy storage safety technology, specifically to a support device and its thermal insulation support module, and an energy storage container testing equipment. Background Technology

[0002] An energy storage container is a mobile energy storage device that integrates an energy storage system into a standard container. Its main function is to store electrical energy. It can be charged when the grid load is low and discharged when the load is high, thus playing a role in peak shaving and valley filling, balancing grid power, and improving grid stability and reliability.

[0003] Existing insulation measures for energy storage containers mostly involve installing insulation layers inside the container, such as adding a fireproof insulation layer (fireproof cotton, fireproof boards, etc.) of a certain thickness. However, this insulation method is designed for actual installation scenarios of energy storage containers. In experimental testing scenarios, however, there are no insulation layers inside the energy storage containers. Therefore, if an energy storage container catches fire, there will be a strong thermal feedback to the experimental platform, leading to significant safety hazards in experimental testing scenarios. Utility Model Content

[0004] In view of the above problems, this application provides a support device and its heat-insulating support module and energy storage container testing equipment, which can solve the problem that the lack of internal heat insulation layer in the current experimental testing scenarios of energy storage containers leads to significant safety hazards.

[0005] In a first aspect, this application provides a support device for supporting and insulating an energy storage container on an experimental platform in an energy storage system. The support device includes: a support frame and a multi-layer insulation unit; the support frame includes multiple support columns, multiple first beam columns, and multiple second beam columns; the multiple first beam columns are interconnected to form a first support surface and a first outer surface, and the multiple second beam columns are interconnected to form a second support surface and a second outer surface; wherein the first support surface and the first outer surface are arranged opposite to each other, and the second support surface and the second outer surface are arranged opposite to each other; the support columns are disposed between the first support surface and the second support surface and are connected to the beam columns therein; wherein the first outer surface is used to contact the energy storage container, and the second outer surface is used to contact the experimental platform; the multi-layer insulation unit is disposed in the hollow part of the support frame; wherein the hollow part is formed by one or more of the support columns, first beam columns, and second beam columns.

[0006] The support device designed above uses a support frame to support the energy storage container, and fills the support frame with multiple layers of heat insulation units. This design combines heat insulation and support functions, reducing system complexity and improving system safety and stability. Furthermore, the combination design of multiple layers of heat insulation units significantly reduces the thermal damage of the energy storage container to the experimental platform, thereby improving the safety of the energy storage container's experimental testing.

[0007] In some embodiments, the multilayer insulation unit includes a rigid flame-retardant layer, a buffer insulation layer, and a porous inorganic layer; the buffer insulation layer is disposed between the porous inorganic layer and the rigid flame-retardant layer, the porous inorganic layer is located between the second support surface and the buffer insulation layer, and the rigid flame-retardant layer is located between the buffer insulation layer and the first support surface.

[0008] In the above-described implementation, the three-layer structure design enables the designed multi-layer thermal insulation unit to possess stronger thermal insulation performance. The rigid flame-retardant layer, located on the top layer, can reduce the downward transfer of heat, protect the lower layer materials from direct exposure to high temperatures, and the high rigidity of the rigid flame-retardant layer ensures the stability of the upper structure. The thermal insulation buffer layer can absorb heat and further delay its downward transfer, while preventing stress concentration caused by material thermal expansion, thereby dispersing the pressure on the porous inorganic layer and protecting it. The porous inorganic layer provides excellent thermal insulation performance, effectively preventing heat transfer to the experimental platform. Its porous structure effectively absorbs heat, and the porous inorganic layer has the best thermal insulation performance, forming the final barrier. This allows the designed multi-layer thermal insulation unit to achieve a layer-by-layer heat attenuation effect, thereby improving thermal insulation performance.

[0009] In some embodiments, the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer all have the same length in the connection direction from the first support surface to the second support surface.

[0010] In the above-described implementation, the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are all designed with the same length in the connection direction from the first support surface to the second support surface. This design ensures that the thermal resistance of each layer is relatively uniform, thereby effectively improving the overall insulation effect, maintaining the temperature stability within the support device, and ensuring that its load-bearing capacity and deformation characteristics are also relatively consistent. This improves the overall structural strength and stability of the multi-layer insulation unit and extends its service life.

[0011] In some embodiments, the contact surfaces of the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer all have the same area, wherein the contact surface is a cross-section of the corresponding layer on the plane where the first support surface or the second support surface is located.

[0012] In the above-described implementation, the contact surfaces of the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are all designed to have the same area. This allows for more uniform reflection, absorption, and scattering of heat radiation between the layers, enhancing the ability to block heat radiation, effectively reducing the heat transferred through heat radiation, improving the overall insulation performance of the multi-layer insulation unit, and helping to evenly distribute external forces, resulting in a balanced stress distribution across each layer. Furthermore, it prevents the multi-layer insulation unit of the designed support device from shifting or displacing between layers during use, thus helping to maintain the integrity of the multi-layer insulation unit and avoiding gaps or channels caused by interlayer misalignment. This prevents heat from being rapidly transferred through these weak points, ensuring long-term stability of the insulation performance.

[0013] In some embodiments, the contact surfaces of the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are all the same size as the area of ​​the first support surface, wherein the contact surface is a cross-section of the corresponding layer on the plane of the first or second support surface.

[0014] In the above embodiment, the contact surfaces of the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are all the same size as the first support surface. This allows the multi-layer insulation unit to have the same area as the first support surface, thus ensuring close contact and adhesion. This avoids gaps or channels caused by misalignment between the multi-layer insulation unit and the first support surface, thereby preventing heat from being quickly transferred through these gaps or channels and further improving the stability and reliability of the insulation performance.

[0015] In some embodiments, the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are detachably disposed in the hollow portion of the support frame.

[0016] In the above-described implementation, the rigid flame-retardant layer, the buffer insulation layer, and the porous inorganic layer are detachably installed in the hollow part of the support frame, which facilitates the repair or replacement of specific damaged parts without disassembling or remaking the entire support device. This greatly reduces the difficulty and cost of maintenance. Furthermore, the detachable design makes the installation of the support device simpler and faster. In addition, during transportation, the multi-layer insulation unit can be transported separately from the support frame, which can reduce the overall volume and weight, and reduce the difficulty and cost of transportation.

[0017] In some embodiments, a plurality of first support members and a plurality of second support members are provided on a plurality of support columns; the plurality of first support members are located on a first cross section parallel to a first support surface, and the plurality of second support members are located on a second cross section parallel to the first support surface; wherein, the plurality of first support members are close to the first support surface, and the plurality of second support members are close to the second support surface; a rigid flame-retardant layer is provided on the plurality of first support members, a buffer heat insulation layer is provided on the plurality of second support members, and a porous inorganic layer is provided on the second support surface.

[0018] In the above-described embodiments, this solution achieves the separation of a rigid flame-retardant layer, a buffer insulation layer, and a porous inorganic layer through a simple combination of multiple first and second support members, which are detachable from the support frame, thereby simplifying the structure of the support device.

[0019] In a second aspect, this application provides a thermal insulation support module, which includes a support device according to any optional embodiment of the first aspect; a plurality of support devices are detachably connected to form a support device array.

[0020] The thermal insulation support module designed above can be formed by combining different numbers of support devices according to the size and shape of the container. This allows for quick and flexible adjustments for testing energy storage containers of different sizes and shapes, thereby improving applicability and testing efficiency.

[0021] In some embodiments, the plurality of support columns of the support device includes a first support column group and a second support column group; a connector is provided on the outer surface of the first support column group, and a slot adapted to the connector is provided on the outer surface of the second support column group; wherein, adjacent support devices in the support device array are detachably connected to the slot via the connector.

[0022] In the above-described embodiments, this solution achieves a stable connection of multiple support devices through the cooperation of plug-in components and slots, simplifies the installation and disassembly of the support devices, and enables rapid and flexible adjustment of the support device array while ensuring structural stability.

[0023] Thirdly, this application provides an energy storage container testing device, which includes an energy storage container, an experimental platform, and a support device according to any optional embodiment of the first aspect. The support device is disposed on the experimental platform, the energy storage container is disposed on the support device, the first outer surface of the support device is in contact with the energy storage container, and the second outer surface of the support device is in contact with the experimental platform.

[0024] The energy storage container testing equipment designed above includes the support device described above. Therefore, by placing the support device between the energy storage container and the experimental platform, the energy storage container can be supported by the support device. Furthermore, the multi-layer heat insulation unit of the support device can isolate heat from the energy storage container, thereby preventing thermal runaway of the energy storage container from damaging the experimental platform. This ensures the safety and reliability of the designed energy storage container testing equipment.

[0042] An energy storage container is a mobile energy storage device that integrates an energy storage system into a standard container. Its main function is to store electrical energy. It can be charged when the grid load is low and discharged when the load is high, thus playing a role in peak shaving and valley filling, balancing grid power, and improving grid stability and reliability.

[0043] Existing insulation measures for energy storage containers mostly involve installing insulation layers inside the container, such as adding a fireproof insulation layer (fireproof cotton, fireproof boards, etc.) of a certain thickness. However, this insulation method is designed for actual installation scenarios of energy storage containers. In experimental testing scenarios, however, there are no insulation layers inside the energy storage containers. Therefore, if an energy storage container catches fire, there will be a strong thermal feedback to the experimental platform, leading to significant safety hazards in experimental testing scenarios.

[0044] To address the aforementioned issues, this application designs a support device, its thermal insulation support module, and an energy storage container testing device. By designing a support frame to support the energy storage container and filling the support frame with multiple layers of thermal insulation units, the support device of this design integrates thermal insulation and support functions, reducing system complexity and improving system safety and stability. Furthermore, the combined design of the multiple thermal insulation units significantly reduces thermal damage to the experimental platform from the energy storage container, thereby improving the safety of energy storage container testing. Moreover, the support device designed in this solution can be combined to form thermal insulation support modules according to the size and shape of the container, allowing for rapid and flexible adjustments for testing energy storage containers of different sizes and shapes, thus improving applicability and testing efficiency.

[0045] Based on the above ideas, this application first provides a support device, such as... Figure 1As shown, the support device includes a support frame 10 and a multi-layer heat insulation unit 20. The support frame 10 includes multiple support columns 11, multiple first beam columns 12, and multiple second beam columns 13. The multiple first beam columns 12 are interconnected to form a first support surface 120 and a first outer surface 121. The multiple second beam columns 13 are interconnected to form a second support surface 130 and a second outer surface 131. The first support surface 120 and the first outer surface 121 are arranged opposite to each other, and the second support surface 130 and the second outer surface 131 are arranged opposite to each other. The support columns 11 are disposed between the first support surface 120 and the second support surface 130 and are connected to the beam columns therein. The multi-layer heat insulation unit 20 is disposed in the hollow part 14 of the support frame 10. The hollow part 14 is formed by one or more of the support columns 11, the first beam columns 12, and the second beam columns 13.

[0046] For ease of understanding, this scheme Figure 1 The support frame 10 formed by the multiple support columns 11, multiple first beam columns 12, and multiple second beam columns 13 shown is a right quadrangular prism support frame, but it is only an example of the support frame 10 in this scheme. The support frame designed in this scheme, in addition to Figure 1 Besides the straight rectangular prism support frame shown, this solution can also use a polygonal prism support frame or other forms such as a cylindrical support frame; this solution is not limited in this regard. Furthermore, to improve the rigidity of the support frame 10, the support frame 10 designed in this solution can be made of high-strength low-alloy steel. Of course, the support frame 10 designed in this solution can also be made of other rigid materials, such as stainless steel.

[0047] In the aforementioned design, the first outer surface 121 and the second outer surface 131 of the support frame 10 can contact the outer surfaces when providing support. Specifically, the support device designed in this scheme can be placed between the energy storage container A and the experimental platform B. The first outer surface 121 of the support device contacts the bottom of the energy storage container A, and the second outer surface 131 of the support device contacts the experimental platform B. This allows the designed support device to support the energy storage container. Furthermore, the support frame 10 of the support device designed in this scheme is also equipped with a multi-layer thermal insulation unit 20. This multi-layer thermal insulation unit 20 is formed by combining multiple layers of thermal insulation materials. In the event of thermal runaway of the energy storage container, the multi-layer thermal insulation unit 20 can effectively block the transfer of heat from the energy storage container to the experimental platform, significantly reducing the thermal damage to the experimental platform caused by the energy storage container, thereby improving the safety of the energy storage container's experimental testing. It should be noted that... Figure 1This is a structural diagram depicting the positional relationship between the support device, energy storage container A, and experimental platform B. Its internal structure is merely a possible example and should not be considered a limitation of this solution. The specific internal structures of energy storage container A and experimental platform B can be adjusted according to the actual application scenario.

[0048] The support device designed above supports the energy storage container through a support frame, and fills the support frame with multiple layers of heat insulation units. This allows the support device to combine heat insulation and support functions into one, reducing system complexity and improving system safety and stability. Furthermore, the combination design of multiple layers of heat insulation units significantly reduces the thermal damage of the energy storage container to the experimental platform, thereby improving the safety of the energy storage container's experimental testing.

[0049] In an optional implementation of this embodiment, such as Figure 2 As shown, the multi-layer heat insulation unit 20 designed in this scheme includes a rigid flame-retardant layer 210, a buffer heat insulation layer 220, and a porous inorganic layer 230. The buffer heat insulation layer 220 is disposed between the porous inorganic layer 230 and the rigid flame-retardant layer 210. The porous inorganic layer 230 is located between the second support surface 130 and the buffer heat insulation layer 220. The rigid flame-retardant layer 210 is located between the buffer heat insulation layer 220 and the first support surface 120. This indicates that the multi-layer heat insulation unit 20 designed in this scheme has a multi-layer distribution of porous inorganic layer 230, buffer heat insulation layer 220, and rigid flame-retardant layer 210 from the second support surface 130 to the first support surface 120.

[0050] The multi-layer insulation unit 20 designed above, when providing thermal insulation support for the energy storage container, forms a multi-layered distribution from the second support surface 130 to the first support surface 120, consisting of a porous inorganic layer 230, a buffer insulation layer 220, and a rigid flame-retardant layer 210. Therefore, the rigid flame-retardant layer 210 is close to the energy storage container. Due to its high mechanical strength and high-temperature resistance, the rigid flame-retardant layer 210 not only provides thermal insulation but also offers a certain degree of rigid support. Thus, using the rigid flame-retardant layer 210 to form the first thermal insulation barrier provides excellent thermal insulation and support characteristics. Specifically, the rigid flame-retardant layer 210 used in this design can be any one or more of the following rigid fireproof boards: calcium silicate board, magnesium oxide board, magnesium silicate composite board, and high-density fiber cement board.

[0051] The buffer insulation layer 220 primarily serves for heat insulation and buffering. It can be made from fire-resistant cotton materials, such as rock wool, ceramic fiber wool, basalt wool, aerosol composite insulation cotton, or any combination of one or more of these materials. In the case of multiple combinations, various materials can be combined into a single buffer insulation layer; for example, rock wool and ceramic fiber wool can be combined to form the buffer insulation layer 220. This allows the buffer insulation layer 220, positioned between the rigid flame-retardant layer 210 and the porous inorganic layer 230, to possess excellent fire resistance and a low thermal conductivity, effectively reducing heat conduction and thus mitigating the spread of fire.

[0052] The bottom porous inorganic layer 230 can be made of porous inorganic materials with good thermal conductivity and fire resistance, such as foam glass, high-density foamed ceramic board, high-temperature aluminum silicate foam board, calcium silicate composite foam board, etc., any one or more of these materials combined. In the case of multiple combinations, multiple porous inorganic materials can be assembled to form a porous inorganic layer 230. For example, foam glass and high-temperature aluminum silicate foam board can be combined to form a porous inorganic layer 230. This allows the designed porous inorganic layer 230 to effectively prevent heat from being transferred to the experimental platform.

[0053] The aforementioned multi-layer insulation unit, with its three-layer structure, possesses enhanced insulation performance. The rigid flame-retardant layer, located on the top, reduces downward heat transfer, protecting the lower layers from direct high temperatures. Furthermore, the high rigidity of the flame-retardant layer ensures the stability of the upper structure. The insulation buffer layer absorbs heat and further slows its downward transfer, while preventing stress concentration due to thermal expansion, thus dispersing pressure on the porous inorganic layer and protecting it. The porous inorganic layer provides excellent insulation, effectively preventing heat transfer to the experimental platform. Its porous structure effectively absorbs heat, and its optimal insulation performance forms the final barrier. This design allows the multi-layer insulation unit to achieve a layer-by-layer heat attenuation effect, thereby improving insulation performance.

[0054] It should be noted that, in addition to the three-layer structure design described above, the multi-layer insulation unit 20 designed in this scheme can also be designed with other numbers of insulation layers. For example, if cost is not a concern, the multi-layer insulation unit 20 can contain more than three insulation layers.

[0055] In an optional embodiment of this example, as one possible implementation, the rigid flame-retardant layer 210, the buffer heat insulation layer 220, and the porous inorganic layer 230 designed in this scheme have the same length in the connection direction from the first support surface 120 to the second support surface 130, that is, the thickness of the rigid flame-retardant layer 210, the buffer heat insulation layer 220, and the porous inorganic layer 230 can all be the same.

[0056] In the above-described implementation, the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 are all designed with the same thickness. Regarding insulation performance: thermal resistance is a crucial indicator of the insulation capacity of insulation materials. The uniform thickness of each layer in the multi-layer insulation unit 20 ensures a more uniform thermal resistance across all layers, creating a stable thermal resistance distribution throughout the entire multi-layer insulation unit 20. This results in a more balanced resistance encountered during heat transfer, preventing the "thermal bridge" phenomenon where localized low thermal resistance allows heat to easily pass through. This effectively improves the overall insulation effect and maintains a stable temperature within the support device. Furthermore, the uniform thickness of the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 avoids differences in heat conduction speed caused by variations in layer thickness. If the thicknesses of the layers are uneven, heat will conduct faster in thinner areas, leading to a decrease in insulation performance. Uniform thickness ensures that heat is conducted at a relatively consistent speed across all layers, minimizing heat transfer and achieving better insulation.

[0057] Regarding support: Since the multi-layer insulation unit 20 designed in this scheme is set in the support frame 10, it will also be subjected to the pressure of the energy storage container when supporting it. The uniform thickness of each layer in the multi-layer insulation unit 20 helps to distribute stress evenly throughout the entire unit. Because each layer is the same thickness, its load-bearing capacity and deformation characteristics are also relatively consistent, preventing any layer from bearing excessive stress due to being too thin, thus avoiding premature damage or deformation. This improves the overall structural strength and stability of the multi-layer insulation unit and extends its service life.

[0058] It should be noted that the thicknesses of the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 in this design can be non-uniform. For example, in order to increase the load-bearing capacity of the bottom porous inorganic layer 230, the thickness of the porous inorganic layer 230 in this design can be greater than the thicknesses of the rigid flame-retardant layer 210 and the buffer insulation layer 220. In order to increase the rigidity of the rigid flame-retardant layer 210, the thickness of the rigid flame-retardant layer 210 in this design can be greater than the thickness of the buffer insulation layer.

[0059] In the above-described embodiment, the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 all have the same thickness, thereby improving the insulation performance of the multi-layer insulation unit, enhancing the overall structural strength and stability of the multi-layer insulation unit, and extending its service life.

[0060] In an optional embodiment of this invention, the contact surfaces of the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 in the multi-layer heat insulation unit 20 designed in this scheme all have the same area. The contact surface is the cross-section of the corresponding layer on the plane where the first support surface 120 or the second support surface 130 is located. That is, the cross-sections of the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 are parallel to the first support surface 120 all have the same area.

[0061] In terms of thermal insulation performance, the above-described embodiments allow for uniform heat transfer between layers in the multi-layer insulation unit 20, preventing heat concentration in certain areas due to differences in area between layers. This results in a more stable and balanced thermal insulation effect of the multi-layer insulation unit 20, providing consistent temperature regulation throughout the insulation area and reducing local overheating or undercooling. Furthermore, thermal radiation is a crucial mode of heat transfer in multi-layer insulation. Having identical areas among layers ensures more uniform reflection, absorption, and scattering of thermal radiation between layers, enhancing the ability to block thermal radiation and effectively reducing the amount of heat transferred through radiation, thereby improving the overall thermal insulation performance of the multi-layer insulation unit 20.

[0062] In terms of structural stability: The uniform area of ​​each layer not only helps to evenly distribute external forces and make the force distribution of each layer balanced, but also makes it less likely for the multi-layer thermal insulation unit 20 of the designed support device to misalign or shift between layers during use. This helps to maintain the integrity of the multi-layer thermal insulation unit, avoid gaps or channels caused by misalignment between layers, and prevent heat from being quickly transferred through these weak parts, thus ensuring the long-term stability of thermal insulation performance.

[0063] In an optional embodiment of this example, the contact surfaces of the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 can not only have the same area, but their area can also be the same as the area of ​​the first support surface 120. This allows the multi-layer insulation unit 20 to have the same area as the first support surface 120, thus ensuring close contact and adhesion. This avoids gaps or channels caused by misalignment between the multi-layer insulation unit 20 and the first support surface 120, thereby preventing heat from being quickly transferred through these gaps or channels and further improving the stability and reliability of the insulation performance.

[0064] In an optional embodiment of this example, as one possible implementation, the rigid flame-retardant layer 210, the buffer heat insulation layer 220, and the porous inorganic layer 230 designed in this scheme are detachably disposed in the hollow part 14 of the support frame 10.

[0065] In the above-described implementation, if a certain layer or part of the multi-layer insulation unit 20 is damaged or aged during use, the detachable design makes it easy to remove the multi-layer insulation unit 20 from the support frame 10 to repair or replace the damaged part without disassembling or rebuilding the entire support device. This greatly reduces the difficulty and cost of maintenance. Furthermore, by replacing the damaged or degraded parts in a timely manner, the entire support device can be kept in good working condition, effectively extending the overall service life of the support device and ensuring that it plays a stable role in insulation for a long time.

[0066] Secondly, as usage needs change or environmental conditions change, it may be necessary to adjust the thermal insulation performance. The detachable multi-layer thermal insulation unit 20 makes it easy to increase or decrease the number of thermal insulation layers or replace materials with different materials and properties according to the actual situation, so as to flexibly meet different thermal insulation requirements.

[0067] Furthermore, the detachable design makes the installation of the support device simpler and faster. Specifically, the support frame 10 can be fixed in the designated position first, and then the multi-layer insulation unit 20 can be easily installed into the frame without complicated overall installation operations, which improves installation efficiency and shortens the construction cycle.

[0068] Finally, during transportation, the multi-layer insulation unit 20 can be transported separately from the support frame 10, which can reduce the overall volume and weight, reduce transportation difficulty and cost, and also reduce the risk of damage to the support device during transportation. Then, it can be assembled after arriving at the installation site.

[0069] It should be noted that, in addition to being detachably installed in the hollow part 14 of the support frame 10, the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 of the multi-layer heat insulation unit 20 designed in this scheme can also be fixedly installed in the hollow part 14 of the support frame 10 to form a whole.

[0070] In an optional implementation of this embodiment, such as Figure 3As shown, this solution can achieve the following implementation method: the rigid flame-retardant layer 210, the buffer insulation layer 220, and the porous inorganic layer 230 can be detachably disposed on the hollow part 14 of the support frame 10. Specifically, the multiple support columns 11 designed in this solution are provided with multiple first support members 111 and multiple second support members 112. The multiple first support members 111 are located on a first cross section parallel to the first support surface 120, and the multiple first support members 111 are located on a second cross section parallel to the first support surface. The first cross section and the second cross section are parallel. The multiple first support members 111 are close to the first support surface 120, and the multiple second support members 112 are close to the second support surface 130. The rigid flame-retardant layer 210 is disposed on the multiple first support members 111, the buffer insulation layer 220 is disposed on the multiple second support members 112, and the porous inorganic layer 230 is disposed on the second support surface 130.

[0071] In the above embodiment, this solution provides multiple first support members 111 and multiple second support members 112 on the support column 11, so that the rigid flame retardant layer 210 can be placed on the multiple first support members 111 and the buffer heat insulation layer 220 can be placed on the multiple second support members 112. This makes the rigid flame retardant layer 210, the buffer heat insulation layer 220 and the porous inorganic layer 230 spaced apart and detachable relative to the support frame 10. In this way, the rigid flame retardant layer 210, the buffer heat insulation layer 220 and the porous inorganic layer 230 can be disassembled and installed by pulling.

[0072] Furthermore, the first support member 111 and the second support member 112 designed in this scheme can be a pad or other forms of support member. For example, the first support member 111 and the second support member 112 can also be a groove welded inside the support column 11, wherein the depth and width of the pad or groove can be adaptively adjusted according to the thickness of the heat insulation layer.

[0073] This application also provides a thermal insulation support module, such as Figure 4 As shown, the thermal insulation support module may include multiple support devices 1 as described above, which can be detachably connected to form a support device array.

[0074] The above-designed thermal insulation support module can combine different numbers of support devices 1 to form a thermal insulation support module according to the size and shape of the container. This allows for quick and flexible adjustments for testing energy storage containers of different sizes and shapes, thereby improving applicability and testing efficiency.

[0075] Furthermore, such as Figure 5As shown, each support device 1 in this design includes a first support column group 113 and a second support column group 114. The outer surface of the first support column group 113 is provided with a connector 115, and the outer surface of the second support column group 114 is provided with a slot 116 adapted to the connector 115. The adjacent support devices 1 in the support device array are detachably connected to the slot 116 through the connector 115.

[0076] In the above-described embodiment, this solution achieves a stable connection of multiple support devices 1 through the cooperation of the connector 115 and the slot 116, which simplifies the installation and disassembly of the support devices 1 and allows for rapid and flexible adjustment of the support device array while ensuring structural stability.

[0077] This application also provides a testing device for energy storage containers, such as... Figure 6 As shown, the energy storage container testing equipment includes an energy storage container A, an experimental platform B, and a support device 1 as described above. The support device 1 is mounted on the experimental platform B, and the energy storage container A is mounted on the support device 1. The first outer surface 121 of the support device 1 is in contact with the energy storage container A, and the second outer surface 131 of the support device is in contact with the experimental platform B.

[0078] Energy storage container A is a portable energy storage device that integrates an energy storage system within a standard container. During safety testing of energy storage container A, it is mounted on experimental platform B (which can be an automated lifting platform). The function of experimental platform B is to automatically or manually lower the energy storage container A in the event of thermal runaway or other emergency, immersing it in a pre-set water tank for cooling and fire suppression. Safety testing of the energy storage container may include insulation resistance testing, grounding resistance testing, and charge / discharge performance testing, etc. The automated lifting of the experimental platform can employ any of the following methods: hydraulic drive, screw drive, or pneumatic drive; the specific method can be adapted according to actual conditions.

[0079] In the above-designed energy storage container testing equipment, the support device 1 is set between the energy storage container A and the experimental platform B. The support device 1 can support the energy storage container A, and the multi-layer heat insulation unit 20 of the support device 1 can isolate the heat from the energy storage container A, thereby preventing thermal runaway of the energy storage container A from damaging the experimental platform, thus ensuring the safety and reliability of the designed energy storage container testing equipment.
