Description

Technical Field

[0001] This application relates to the field of hydrogen production technology, and in particular to containers and hydrogen production systems. Background Technology

[0002] Containerized hydrogen production systems are widely used due to their high degree of integration, ease of transportation, and rapid deployment. The internal space of a containerized hydrogen production system is limited, and the various modules of the hydrogen production equipment (such as electrolyzers, feedstock processing modules, gas purification modules, and control modules) are highly integrated inside the container. During transportation, the container acts as a protective shield for the hydrogen production equipment, preventing damage from the external environment; upon arrival at the customer's site, the container then serves as a "factory" providing a sheltered operating environment for the hydrogen production equipment.

[0003] Standardized shipping containers have fixed length, width, and height dimensions. However, as hydrogen production equipment becomes larger and more industrialized, the internal space of containers is becoming increasingly cramped, causing numerous inconveniences for the operation, maintenance, and repair of hydrogen production equipment. In particular, when operating or repairing the side of the hydrogen production equipment, the side panels of the container create space constraints, limiting the operator's range of movement and making it difficult to complete the work efficiently.

[0004] In related technologies, the side panels of the container are designed to be openable, allowing operators to inspect and maintain the hydrogen production equipment inside the container. However, to facilitate operations, it is also necessary to carry out civil engineering construction on the outside of the container, build an operating platform for the operators, and erect a sunshade and rainproof canopy above the platform, resulting in a significant amount of construction work. Utility Model Content

[0005] Therefore, it is necessary to provide a container and hydrogen production system to address the problem that containerized hydrogen production systems in related technologies require civil engineering and ground construction outside the container to facilitate operator work, build an operating platform for operators, and erect a sunshade and rainproof canopy above the operating platform, which involves a large amount of construction work.

[0006] One embodiment of this application provides a container, the container comprising:

[0007] frame;

[0008] A first side panel, located on one side of the frame along a first direction, includes an upper door panel and a lower door panel. The upper end of the upper door panel is rotatably connected to the top of the frame about an axis in a second direction, and the lower door panel is rotatably connected to the bottom of the frame about an axis in a second direction.

[0009] The drive unit is used to drive the upper door panel to rotate so that the upper door panel can switch between an open position and a closed position. The drive unit is also used to drive the lower door panel to rotate so that the lower door panel can switch between an open position and a closed position.

[0010] When both the upper and lower door panels are in the open position, the upper and lower door panels are opposite each other along a third direction, so that the upper door panel forms a light-shielding and rain-proof panel, and the lower door panel forms an operating platform, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0011] In one embodiment, the driving device includes a first driving mechanism and a second driving mechanism. The first driving mechanism is connected to the upper door panel and is used to drive the upper door panel to switch between an open position and a closed position. The second driving mechanism is connected to the lower door panel and is used to drive the lower door panel to switch between an open position and a closed position.

[0012] In one embodiment, the first side panel includes two side panel bodies spaced apart along a second direction, with the upper door panel and the lower door panel both located between the two side panel bodies;

[0013] A first drive mechanism is provided at each end of the upper door panel along the second direction, and the two first drive mechanisms are respectively connected to the two side panel bodies;

[0014] A second drive mechanism is provided at each end of the lower door panel along the second direction, and the two second drive mechanisms are respectively connected to the two side panel bodies.

[0015] In one embodiment, the first driving mechanism includes a first hydraulic rod, one end of which is connected to the side panel body and the other end of which is connected to the upper door panel.

[0016] In one embodiment, the second drive mechanism includes a second hydraulic rod, one end of which is connected to the side panel body and the other end of which is connected to the lower door panel.

[0017] In one embodiment, the second drive mechanism further includes a linkage assembly, and the second hydraulic rod is connected to the lower door panel through the linkage assembly;

[0018] The linkage assembly has a folded state and an unfolded state. When the lower door panel is in the closed position, the linkage assembly is in the folded state; when the lower door panel is in the open position, the linkage assembly is in the unfolded state to form a guardrail structure.

[0019] In one embodiment, the linkage assembly includes a crossbar and a plurality of parallel and spaced vertical bars, one end of which is rotatably connected to the lower door panel about an axis in a second direction, and the other end of which is rotatably connected to the crossbar about an axis in a second direction.

[0020] When the lower door panel is in the open position, the vertical bar extends in the third direction, and the horizontal bar extends in the first direction.

[0021] One end of the second hydraulic rod is rotatably connected to one end of the crossbar.

[0022] In one embodiment, the rotation range of the upper door panel relative to the frame is a first rotation range, and the open position and closed position of the upper door panel are located at both ends of the first rotation range;

[0023] The rotation range of the lower door panel relative to the frame is the second rotation range, and the open and closed positions of the lower door panel are located at the two ends of the second rotation range.

[0024] One embodiment of this application provides a hydrogen production system, including a container as described above, with hydrogen production equipment installed inside the container.

[0025] In one embodiment, the hydrogen production system includes at least two containers, with adjacent containers spaced apart along a first direction, and the first side panels of the adjacent containers being arranged opposite each other along the first direction.

[0026] When the lower doors of the first side panels of two adjacent containers are both in the open position, the two lower doors are joined together to form an interconnected operating platform.

[0027] During transportation or normal use, the upper and lower doors of the container are both in the closed position, and the first side panel provides overall protection for the internal hydrogen production equipment from one side of the container along the first direction. If inspection and maintenance of the internal hydrogen production equipment is required, the operator can drive the upper and lower doors to rotate via a drive device, switching them from the closed to the open position. At this time, the upper and lower doors, facing each other along the third direction, respectively form a sunshade / rain shelter and an operating platform. The operator can stand on the operating platform formed by the lower door to inspect and maintain the internal hydrogen production equipment, while the sunshade / rain shelter formed by the upper door protects the operator from sunlight and rain. Therefore, in this embodiment of the container, when both the upper and lower doors are in the open position, the operator can not only inspect and maintain the internal hydrogen production equipment, but the lower door can also serve as an operating platform, and the upper door provides sunshade and rain protection, eliminating the need for civil engineering floor construction and the erection of sunshade / rain shelters, thus greatly reducing the workload.

[0045] Please refer to Figure 1 One embodiment of this application provides a container 10, which includes a frame 100, a first side panel 200, and a drive device.

[0046] Define a first direction YY', a second direction XX', and a third direction ZZ', wherein the first direction YY', the second direction XX', and the third direction ZZ' are all perpendicular to each other.

[0047] Specifically, in this embodiment, the container 10 is used in a hydrogen production system to house hydrogen production equipment. The frame 100 is the overall supporting skeleton of the container 10. In actual use, the third direction ZZ' can be vertical, while the first direction YY' and the second direction XX' are both horizontal. The second direction XX' can be along the length of the container 10.

[0048] The container 10 includes a top plate and a bottom plate, which are respectively disposed on the frame 100 and opposite to each other, and are respectively disposed on both sides of the frame along the third direction ZZ'. The container 10 includes a first side plate 200 and a second side plate disposed opposite to each other along the first direction YY', which are respectively disposed on the frame 100 and located on both sides of the frame 100 along the first direction YY'. The container 10 includes a third side plate and a fourth side plate disposed opposite to each other along the second direction XX', which are respectively disposed on the frame 100 and located on both sides of the frame 100 along the second direction XX'.

[0049] The first side panel 200 is located on one side of the frame 100 along the first direction YY'. The first side panel 200 includes an upper door panel 210 and a lower door panel 220. The upper end of the upper door panel 210 is rotatably connected to the top of the frame 100 about the axis of the second direction XX', and the lower door panel 220 is rotatably connected to the bottom of the frame 100 about the axis of the second direction XX'.

[0050] The drive device is used to drive the upper door panel 210 to rotate, so that the upper door panel 210 switches between the open position and the closed position. The drive device is also used to drive the lower door panel 220 to rotate, so that the lower door panel 220 switches between the open position and the closed position.

[0051] When both the upper door panel 210 and the lower door panel 220 are in the open position, the upper door panel 210 and the lower door panel 220 are opposite each other along the third direction ZZ', so that the upper door panel 210 forms a light-shielding and rain-proof panel, and the lower door panel 220 forms an operating platform.

[0052] During transportation or normal use, the upper door panel 210 and lower door panel 220 of the container 10 are both in the closed position. The first side panel 200 can protect the hydrogen production equipment inside the container 10 from one side along the first direction YY'. If it is necessary to inspect and maintain the hydrogen production equipment inside the container 10, the operator can drive the upper door panel 210 and lower door panel 220 to rotate via the drive device, switching them from the closed position to the open position. At this time, the upper door panel 210 and lower door panel 220, which are opposite each other along the third direction ZZ', respectively form a sunshade and rainproof panel and an operating platform. The operator can stand on the operating platform formed by the lower door panel 220 to inspect and maintain the hydrogen production equipment inside the container 10, while the sunshade and rainproof panel formed by the upper door panel 210 can shield the operator from sunlight and rain. Therefore, when both the upper door panel 210 and the lower door panel 220 of the container 10 in this embodiment are in the open position, the operator can not only inspect and maintain the hydrogen production equipment inside the container 10, but also the lower door panel 220 can serve as an operating platform and the upper door panel 210 can serve as a shade and rain shelter, saving the work of civil engineering floor construction and building shade and rain shelters, thereby greatly reducing the amount of construction work.

[0053] like Figure 1 As shown, when the upper door panel 210 is in the open position, its extension direction is approximately horizontal, thus serving as a sunshade and rain shield. When the lower door panel 220 is in the open position, its extension direction is also approximately horizontal, thus serving as a horizontal support plate, i.e., an operating platform.

[0054] Please combine Figure 1 and Figure 2 In some embodiments, the frame 100 includes a first upper crossbeam 110 and a first lower crossbeam 120. The upper end of the upper door panel 210 is rotatably connected to the first upper crossbeam 110 about a rotation axis in a second direction XX', and the lower end of the lower door panel 220 is rotatably connected to the first lower crossbeam 120 about a rotation axis in the second direction XX'. The frame 100 may also include multiple columns. The first upper crossbeam 110 and the first lower crossbeam 120 can be connected by the columns. The frame 100 may also include other crossbeams, which will not be described in detail here.

[0055] Please combine Figure 1 and Figure 2 In some embodiments, when both the upper door panel 210 and the lower door panel 220 are in the open position, an opening 101 is formed on the side of the frame 100 where the upper door panel 210 and the lower door panel 220 are located, and the opening 101 connects the interior and exterior of the frame 100. When both the upper door panel 210 and the lower door panel 220 are in the closed position, the upper door panel 210 and the lower door panel 220 together close the opening 101.

[0056] The frame 100 has the aforementioned opening 101 formed on one side along the first direction YY'. When both the upper door panel 210 and the lower door panel 220 are in the closed position, they together close the opening 101, thereby allowing the first side panel 200 as a whole to protect the hydrogen production equipment inside the container 10. When the upper door panel 210 and the lower door panel 220 are in the open position, that is, when the opening 101 is open, operators can inspect and maintain the hydrogen production equipment inside the container 10 through the opening 101.

[0057] Combination Figure 1 and Figure 2 Understandably, when the upper door panel 210 is in the closed position, its extension direction is roughly vertical, and when the lower door panel 220 is in the closed position, its extension direction is roughly vertical, so that the two can jointly close the opening 101.

[0058] Specifically, when both the upper door panel 210 and the lower door panel 220 are in the closed position, the ends of the upper door panel 210 and the lower door panel 220 that are close to each other are sealed together to ensure airtightness. For example, a sealing strip can be provided at the end of the upper door panel 210 that is close to the lower door panel 220, and / or a sealing strip can be provided at the end of the lower door panel 220 that is close to the upper door panel 210. The sealing strips seal the ends of the upper door panel 210 and the lower door panel 220 that are close to each other.

[0059] Please combine Figure 1 and Figure 2 In some embodiments, the rotation range of the upper door panel 210 relative to the frame 100 is a first rotation range, and the open position and closed position of the upper door panel 210 are located at both ends of the first rotation range.

[0060] The rotation range of the lower door panel 220 relative to the frame 100 is the second rotation range, and the open and closed positions of the lower door panel 220 are located at the two ends of the second rotation range.

[0061] By limiting the rotation range of the upper door panel 210 to the first rotation range and the rotation range of the lower door panel 220 to the second rotation range, it is ensured that the upper door panel 210 and the lower door panel 220 can accurately reach their respective open or closed positions when switching positions.

[0062] When the hydrogen production equipment inside container 10 requires inspection and maintenance, the upper door panel 210 rotates to the open position within the first rotation range, stably forming a sunshade. The lower door panel 220 rotates to the open position within the second rotation range, stably serving as an operating platform. The positional accuracy of both ensures that the opening 101 is fully open, facilitating operation. When container 10 is in transport or normal use, the upper door panel 210 and lower door panel 220, at the other end of their respective rotation ranges (closed position), can jointly close the opening 101, ensuring the container's airtightness. This limitation on the rotation range avoids functional failures caused by excessive or insufficient rotation of the upper door panel 210 and lower door panel 220, such as poor sunshade and rain protection, unstable operating platform, or incomplete sealing when closed. This reliably achieves both operational convenience when open and equipment protection when closed.

[0063] The range of rotation can be limited by setting a mechanical limiting structure. For example, a first limiting block with a protrusion is set at the rotational connection between the frame 100 and the upper door panel 210. When the upper door panel 210 rotates to the open position, the edge of the upper door panel 210 abuts against the first limiting block and cannot continue to rotate. Similarly, a second limiting block with a protrusion is set at the rotational connection between the frame 100 and the upper door panel 210. When the upper door panel 210 rotates to the closed position, the edge of the upper door panel 210 abuts against the second limiting block, limiting the upper door panel 210 from rotating excessively. Similarly, a raised third limiting block is provided at the rotational connection between the frame 100 and the lower door panel 220. When the lower door panel 220 is rotated to the open position, the edge of the lower door panel 220 abuts against the third limiting block and cannot continue to rotate. Likewise, a raised fourth limiting block is provided at the rotational connection between the frame 100 and the lower door panel 220. When the lower door panel 220 is rotated to the closed position, the edge of the lower door panel 220 abuts against the fourth limiting block, thus restricting the lower door panel 220 from rotating excessively.

[0064] The rotation range of the upper door panel 210 can also be limited by the stroke control of the drive device itself. For example, a limit switch can be set at the frame 100 corresponding to the open position that the upper door panel 210 needs to reach, and a trigger can be set at the corresponding position of the upper door panel 210. Similarly, a limit switch and a corresponding trigger can also be set at the frame 100 corresponding to the closed position of the upper door panel 210. When the drive unit drives the upper door panel 210 to rotate from the closed position to the open position, as the upper door panel 210 rotates, its trigger gradually approaches the limit switch in the open position. When the upper door panel 210 reaches the preset open position, the trigger activates the limit switch, which then sends a signal to the drive unit to cut off the drive power. The upper door panel 210 then stops rotating and stabilizes in the open position. When the upper door panel 210 rotates from the open position to the closed position, the limit switch in the closed position will be triggered when the upper door panel 210 reaches the corresponding position, similarly cutting off the power and causing the upper door panel 210 to stop precisely in the closed position. In this way, the rotation range of the upper door panel 210 is limited by the trigger control of the limit switch.

[0065] Understandably, limiting the rotation range of the lower door panel 220 by controlling the stroke of the drive device itself is the same principle as limiting the rotation range of the upper door panel 210 by controlling the stroke of the drive device itself, and will not be described in detail here.

[0066] Please combine Figure 1 and Figure 2 In some embodiments, the driving device includes a first driving mechanism 300 and a second driving mechanism 400. The first driving mechanism 300 is connected to the upper door panel 210 and is used to drive the upper door panel 210 to open or close. The second driving mechanism 400 is connected to the lower door panel 220 and is used to drive the lower door panel 220 to open or close.

[0067] By setting up independent first drive mechanism 300 and second drive mechanism 400 to drive the upper door panel 210 and lower door panel 220 respectively, independent control and operation of the two can be achieved. In this way, the operator can control the opening and closing of the upper door panel 210 or the lower door panel 220 separately according to actual needs, such as opening only the lower door panel 220 for simple operation, or closing only the upper door panel 210, thus improving operational flexibility.

[0068] Please combine Figure 1 and Figure 2 In some embodiments, the first side panel 200 includes two side panel bodies 230 spaced apart along a second direction XX', with the upper door panel 210 and the lower door panel 220 located between the two side panel bodies 230. The two side panel bodies 230 are respectively the first side panel body 231 and the second side panel body 232.

[0069] The upper door panel 210 is provided with a first drive mechanism 300 at each end along the second direction XX', and the two first drive mechanisms 300 are respectively connected to the two side panel bodies 230.

[0070] A second drive mechanism 400 is provided at each end of the lower door panel 220 along the second direction XX', and the two second drive mechanisms 400 are respectively connected to the two side panel bodies 230.

[0071] By positioning the upper door panel 210 and the lower door panel 220 between the first side panel body 231 and the second side panel body 232, and by providing a first drive mechanism 300 and a second drive mechanism 400 connected to the two side panel bodies at both ends of the upper door panel 210 and the lower door panel 220 along the second direction XX', the force on the upper door panel 210 and the lower door panel 220 is more evenly and symmetrically distributed. This avoids door panel tilting, jamming, or deformation caused by single-end drive, ensuring smoother rotation of the upper door panel 210 and the lower door panel 220 and precise switching to the open or closed position. At the same time, the two side panel bodies 230 enhance the installation firmness of the first drive mechanism 300 and the second drive mechanism 400.

[0072] Please combine Figure 1 and Figure 2 In some embodiments, the first drive mechanism 300 includes a first hydraulic rod 310, one end of which is connected to the side panel body 230 and the other end is connected to the upper door panel 210.

[0073] Specifically, the first drive mechanism 300 located on the side of the upper door panel 210 near the first side panel body 231 has one end of its first hydraulic rod 310 connected to the first side panel body 231, and the other end connected to the end of the upper door panel 210 near the first side panel body 231. Similarly, the first drive mechanism 300 located on the side of the upper door panel 210 near the second side panel body 232 has one end of its first hydraulic rod 310 connected to the second side panel body 232, and the other end connected to the end of the upper door panel 210 near the second side panel body 232.

[0074] The side panel body 230 and the upper door panel 210 are connected by a first hydraulic rod 310, and the upper door panel 210 is driven to rotate by the extension and retraction characteristics of the hydraulic rod. The hydraulic drive can provide stable and controllable power, ensuring that the upper door panel 210 runs smoothly when opening and closing, and stops precisely at the preset open and closed positions, improving the reliability and convenience of operation.

[0075] Please combine Figure 1 and Figure 2 In some embodiments, the second drive mechanism 400 includes a second hydraulic rod 410, one end of which is connected to the side panel body 230 and the other end is connected to the lower door panel 220.

[0076] Specifically, the second drive mechanism 400 located on the side of the lower door panel 220 near the first side panel body 231 has one end of its second hydraulic rod 410 connected to the first side panel body 231 and the other end connected to the end of the lower door panel 220 near the first side panel body 231. Similarly, the second drive mechanism 400 located on the side of the lower door panel 220 near the second side panel body 232 has one end of its second hydraulic rod 410 connected to the second side panel body 232 and the other end connected to the end of the lower door panel 220 near the second side panel body 232.

[0077] The side panel body 230 and the lower door panel 220 are connected by a second hydraulic rod 410, and the lower door panel 220 is driven to rotate by the extension and retraction characteristics of the hydraulic rod. The hydraulic drive can provide stable and controllable power, ensuring that the lower door panel 220 runs smoothly when opening and closing, and stops precisely at the preset open and closed positions, improving the reliability and convenience of operation.

[0078] Please combine Figure 1 and Figure 2 In some embodiments, the second drive mechanism 400 includes a linkage assembly 420, and the second hydraulic rod 410 is connected to the lower door panel 220 via the linkage assembly 420. The linkage assembly 420 has a folded state and an unfolded state. When the lower door panel 220 is in the closed position, the linkage assembly 420 is in the folded state; when the lower door panel 220 is in the open position, the linkage assembly 420 is in the unfolded state to form a guardrail structure.

[0079] When the lower door panel 220 is in the closed position, the linkage assembly 420 is folded, saving space and facilitating its storage. When the lower door panel 220 is opened to form an operating platform, the linkage assembly 420 unfolds into a guardrail structure, ensuring operator safety and preventing accidental falls. Simultaneously, by transmitting the driving force of the second hydraulic rod 410 through the linkage assembly 420, the lower door panel 220 rotates more smoothly, improving the overall stability and reliability of the mechanism. When the lower door panel 220 is open, the linkage assembly 420 also provides tension, i.e., suspension force, to the lower door panel 220, enhancing its support strength for the operator.

[0080] Since a second drive mechanism 400 is provided at each end of the lower door panel 220 along the second direction XX', when the lower door panel 220 is in the open position, the connecting rod assemblies 420 of the two second drive mechanisms 400 respectively form a guardrail structure, that is, guardrail structures are provided at both ends of the lower door panel 220, which fully ensures the safety of the operator.

[0081] Please combine Figures 1 to 3In some embodiments, the linkage assembly 420 includes a horizontal bar 421 and a plurality of parallel and spaced vertical bars 422. One end of each vertical bar 422 is rotatably connected to the lower door panel 220 about an axis in a second direction XX', and the other end of each vertical bar 422 is rotatably connected to the horizontal bar 421 about an axis in the second direction XX'. One end of the second hydraulic rod 410 is rotatably connected to one end of the horizontal bar 421. When the lower door panel 220 is in the open position, the vertical bar 422 extends along a third direction ZZ', and the horizontal bar 421 extends along a first direction YY'.

[0082] like Figure 2 As shown, when the lower door panel 220 is closed, the extension direction of the vertical rod 422 is not along the third direction ZZ' (but is inclined to the third direction ZZ'), the extension direction of the horizontal rod 421 is along the third direction ZZ', the linkage assembly 420 is in an overall retracted state (i.e., folded state), and the second hydraulic rod 410 is in a retracted state (i.e., initial length state).

[0083] Combination Figure 2 and Figure 1 as well as Figure 3 When the lower door panel 220 is opened, the second hydraulic rod 410 extends, thereby pushing the crossbar 421 to move outward along the first direction YY' of the container 10, and the crossbar 421 rotates relative to the second hydraulic rod 410. Simultaneously, one end of the vertical rod 422 rotates relative to the lower door panel 220 about the axis of the second direction XX', and the other end of the vertical rod 422 rotates relative to the crossbar 421 about the axis of the second direction XX'.

[0084] As the lower door panel 220 gradually opens, the extension direction of the vertical bar 422 gradually tends towards the third direction ZZ', and the extension direction of the horizontal bar 421 gradually tends towards the first direction YY'. Until the lower door panel 220 reaches the open position, the vertical bar 422 extends stably along the third direction ZZ', and the horizontal bar 421 extends stably along the first direction YY', thus the linkage assembly 420 forms a guardrail structure. At this time, the second hydraulic rod 410 is in and remains in the extended state.

[0085] When the lower door panel 220 begins to close, the second hydraulic rod 410 retracts, pulling the crossbar 421 towards the inside of the container 10 along the first direction YY', and the crossbar 421 rotates relative to the second hydraulic rod 410. Simultaneously, one end of the vertical rod 422 rotates relative to the lower door panel 220 about the axis of the second direction XX', and the other end of the vertical rod 422 rotates relative to the crossbar 421 about the axis of the second direction XX'.

[0086] As the lower door panel 220 gradually closes, the extension direction of the vertical rod 422 gradually deviates from the third direction ZZ', and the extension direction of the horizontal rod 421 gradually deviates from the first direction YY'. Until the lower door panel 220 reaches the closed position, the extension directions of the horizontal rod 421 and the vertical rod 422 stabilize, and the linkage assembly 420 returns to the folded storage state.

[0087] In this embodiment, when the lower door panel 220 is in the open position, the vertical rod 422 extends along a third direction ZZ', and the horizontal rod 421 extends along a first direction YY'. The horizontal rod 421 extending along the first direction YY' and the multiple parallel-spaced vertical rods 422 can effectively prevent people from falling. Simultaneously, the linkage assembly 420 can be folded away when the lower door panel 220 is closed, saving storage space. The multiple parallel-spaced vertical rods 422 can provide sufficient suspension force for the lower door panel 220, further enhancing the support strength of the lower door panel 220 for the operator.

[0088] Specifically, refer to Figure 3 The vertical rod 422 is provided with a first connecting hole (unnumbered) at one end near the horizontal rod 421. The horizontal rod 421 is provided with a second connecting hole corresponding to the first connecting hole. By providing a pin 423 corresponding to the first connecting hole and the second connecting hole, the pin 423 passes through the corresponding first connecting hole and the second connecting hole, so that the vertical rod 422 and the horizontal rod 421 can be rotatably connected by the pin 423.

[0089] Furthermore, one end of the second hydraulic rod 410 can be connected to one axial end of the pin 423, thereby indirectly connecting it to the crossbar 421 via the pin 423. Thus, when the second hydraulic rod 410 performs telescopic movement, it can push or pull the crossbar 421 through the pin 423.

[0090] One embodiment of this application provides a hydrogen production system, including a container 10 as described in any of the above embodiments, wherein a hydrogen production device is installed inside the container 10.

[0091] Please refer to Figure 4 In one embodiment, two adjacent containers 10 are spaced apart, and the first side panels 200 of the two adjacent containers 10 are positioned opposite each other. The distance between two adjacent containers 10 is approximately twice the width of a lower door panel 220. Thus, when the lower door panels 220 of the first side panels 200 of both containers 10 are in the open position, the two lower door panels 220 are joined together to form an interconnected operating platform. This allows operators to work flexibly between the two containers 10, facilitating equipment maintenance and material handling across containers, while also ensuring operational safety through the guardrail formed by the linkage assembly 420 when the lower door panels 220 are open.

[0092] In this embodiment, the width of the lower door panel 220 refers to the dimension of the lower door panel 220 along the first direction YY' when it is in the open position.

[0093] Furthermore, adjacent lower door panels 220 can be further connected and fixed together using connectors to improve the splicing stability of the two adjacent lower door panels 220. Connectors may include, for example, snap-fit ​​connectors or bolt connectors.

[0094] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
