[0084] Reference Figures 1 to 11 This utility model provides a container 10. The container 10 mainly includes a frame assembly and a wall panel assembly. The frame assembly includes a top frame 300 located at the top of the container 10, a bottom frame 200 located at the bottom of the container 10, and a plurality of uprights 400 located between the top frame 300 and the bottom frame 200. The wall panel assembly includes a top plate 700, a bottom plate, and side walls. The top plate 700 is located at the top of the frame assembly and is laid on the top frame 300; the top plate 700 and the top frame 300 together form the top of the container 10. The bottom plate is located at the bottom of the frame assembly and, together with the bottom frame 200, forms the bottom of the container 10. The side walls include side panels and end panels. The side panels are located on both sides of the frame assembly in the width direction DW. The end panels are located at both ends of the frame assembly in the length direction DL. The wall panel assembly also includes a door optionally located on at least one of the side panels and end panels. An openable door can be installed at any position on the side panels and end panels according to usage requirements. (See reference...) Figures 1 to 3 , Figures 7 to 10 This utility model has doors on both side panels and both end panels.

[0085] The container 10 provided by this utility model is used to install hydrogen production equipment. Although containerized hydrogen production stations have many advantages, they also have the problem of inconvenient equipment installation and wiring.

[0086] To address the installation issues of pipelines and cables when installing hydrogen production equipment in a container, the container 10 provided by this utility model is equipped with a threshold 100. An opening connecting the internal and external spaces of the container 10 is formed in the side wall of the container 10. This opening can be formed in the side panel or end panel and is used to install components such as a door or the threshold 100. Optionally, the opening is formed by the base frame 200, the top frame 300, and two adjacent columns 400 located on the same side wall of the container 10.

[0087] The threshold 100 is detachably connected to the bottom edge of the opening and the two sides of the opening. The first door 510 is pivotally connected to the side of the opening and is located vertically above the threshold 100.

[0088] In this solution, multiple through holes 111 connecting the interior and exterior spaces of the container 10 are created on the threshold 100, solving the problem of inconvenient equipment installation and wiring, and fulfilling the requirements for pipe and / or cable routing. By placing the through holes 111 on the removable threshold 100, rather than directly drilling holes in the container door, the adverse effects of drilling on the structural strength of the container door are avoided, ensuring the overall stability and durability of the container door. Furthermore, since the container door does not require drilling, it can be directly manufactured using standard parts without additional processing. This not only simplifies the manufacturing process but also saves time and costs, improving production efficiency.

[0089] Reference Figure 4 and Figure 5 The threshold 100 includes a threshold body 110, a bottom folded edge 120, a side folded edge 130, and a top folded edge 140. Optionally, the bottom folded edge 120, the side folded edge 130, and the top folded edge 140 are all located on the side of the threshold body 110 facing the interior space of the container 10. The threshold body 110 has a through hole 111 for threading pipes and / or cables. The bottom folded edge 120 is connected to the bottom edge of the threshold body 110 and is used to connect to the bottom edge of the opening, optionally connected to the base frame 200. The side folded edge 130 is connected to the side edge of the threshold body 110 and is used to connect to the side of the opening, optionally connected to the post 400. The top folded edge 140 is connected to the top edge of the threshold body 110 and faces the first container door 510.

[0090] In this design, the threshold 100 is connected to the base frame 200 via the bottom folded edge 120 and to the upright 400 via the side folded edge 130, thus tightly integrating with the frame components of the container 10 and enhancing the overall structural stability of the container 10. Optionally, the threshold 100 is detachably connected to the bottom edge of the opening; specifically, the bottom folded edge 120 is detachably connected to the base frame 200. The threshold 100 is also detachably connected to the side edge of the opening; specifically, the side folded edge 130 is detachably connected to the upright 400. Thus, the threshold 100 is detachably connected to the container 10. The detachable connection method is bolted connection. Optionally, the bottom folded edge 120 and the side folded edge 130 of the threshold 100 are provided with connecting holes 102, which can be connected to bolts 101. With the detachable threshold 100, when forklifts are used to move equipment into the container, the threshold 100 can be removed first, and then reinstalled and secured after the equipment is installed.

[0091] Optionally, after the threshold 100 is installed and fixed, the surrounding area should be sealed with adhesive to effectively prevent rainwater from entering the box and ensure the normal operation environment of the hydrogen production equipment.

[0092] As described above, the first door 510 is pivotally connected to the side of the opening, and the first door 510 is located vertically above the threshold 100. Specifically, the threshold 100 and the top frame 300 are spaced apart along the height direction DH of the container 10. The first door 510 is installed between the threshold 100 and the top frame 300. The first door 510 includes a door body 501. Optionally, the door body 501 is a double-door structure. The double-door structure design makes the door body 501 more convenient to open and close, providing more passage space and facilitating the entry and exit of personnel and equipment.

[0093] Back Figure 2 and Figure 3 Optionally, the first door 510 has multiple locking rods 502 on the side facing the outside space. The threshold 100 has multiple locking seats 503 on the side facing the outside space, the number of which is equal to the number of locking rods 502 and they fit together. Optionally, the top frame 300 also has multiple locking seats 503, the number of which is equal to the number of locking rods 502 and they fit together. That is, the total number of locking seats 503 on the threshold 100 and the top frame 300 is twice the number of locking rods 502. The locking seats 503 on the threshold are located in the lower region of the locking rods 502 and are connected to the lower end of the locking rods 502; the locking seats 503 on the top frame 300 are located in the upper region of the locking rods 502 and are connected to the upper end of the locking rods 502. When the door 501 is closed, the locking rod 502 can be inserted into the lock seat 503 to reliably lock the door 501, while also facilitating quick opening and closing of the cabinet door by staff. Optionally, the lock seat 503 is welded to the top frame 300 and fixed to the threshold 100, or fixedly connected by fasteners.

[0094] Continue to refer to Figure 4 and Figure 5 Due to the large span of the threshold 100, a flange 150 is included to ensure its strength. The flange 150 is located on the side of the threshold 100 facing the interior space of the container 10. Simultaneously, since the first door 510 is operable, the flange 150 is positioned at the top of the threshold 100 to enhance the strength of the top and prevent deformation of the top of the threshold 100 from affecting the opening and closing of the door 501. Specifically, the flange 150 is connected to the edge of the top folded edge 140 away from the threshold body 110, and the flange 150 is opposite to and spaced apart from the threshold body 110. The flange 150 creates a channel-like structure at the top of the threshold 100, effectively improving its bending and torsional stiffness, reducing the risk of deformation and damage, and ensuring the long-term stability and reliability of the threshold 100, thus guaranteeing the normal opening and closing of the door.

[0095] Optionally, the side of the sill 100 facing the interior space of the container 10 is connected to multiple reinforcing ribs 160, the positions of which correspond to the positions of the lock seat 503. Optionally, the reinforcing ribs 160 are located between the top folded edge 140 and the bottom folded edge 120 of the sill 100. Optionally, in the projection along the width direction DW of the container 10, the lock seat 503 and the reinforcing ribs 160 at least partially overlap, that is, the lock seat 503 is located in a position of high rigidity of the sill 100. As the direct force-bearing point of the locking force of the first door 510, the lock seat 503 can transmit the impact force when the door 501 is closed to the rigid reinforcement area of ​​the sill 100, ensuring the stability of the lock seat 503 and reducing the deformation of the sill 100.

[0096] The top end of the reinforcing rib 160 is connected to the top flange 140, and the bottom end of the reinforcing rib 160 is connected to the bottom flange 120. The reinforcing rib 160 extends along the height direction DH of the container 10. The arrangement of the reinforcing rib 160 can disperse stress and effectively enhance the stability of local areas of the sill 100, ensuring the overall structural integrity and safety of the sill 100. At the same time, since the top end of the reinforcing rib 160 is connected to the top flange 140, it can enhance the strength of the top of the sill 100 and avoid the impact of deformation of the top of the sill 100 on the opening and closing of the door 501. Optionally, the reinforcing rib 160 is welded to at least one of the top flange 140, the bottom flange 120, and the sill body 110, or fixedly connected by fasteners.

[0097] As described above, the combination of the flange 150 and the reinforcing rib 160 forms a stable support system. This layout allows the stress on the threshold 100 to be distributed more evenly throughout the structure when it is under stress, avoiding damage caused by local stress concentration and extending the service life of the threshold 100.

[0098] Optionally, the reinforcing rib 160 is staggered from the through hole 111. The reinforcing rib 160 can fully exert its reinforcing effect on the sill 100. At the same time, the through hole 111 and the reinforcing rib 160 do not interfere with each other, and the reinforcing rib 160 will not affect the normal installation and routing of pipes and cables.

[0099] Optionally, the number of through holes 111 can be one or more. Depending on the usage requirements, through holes 111 can be provided at any position on the threshold body 110 that is offset from the reinforcing rib 160.

[0100] In this solution, the sill 100 is integrally formed by pressing and bending the sheet metal. According to this solution, the sill body 110, bottom folded edge 120, side folded edge 130, top folded edge 140, and flange 150 are integrally formed on a single sheet metal using a pressing and bending process. This integral forming design reduces the steps of individual processing and assembly, significantly improving production efficiency and enhancing the aesthetics of the sill 100. Simultaneously, when subjected to external forces, the components work together to better distribute and bear stress, improving the sill 100's resistance to bending, shearing, and torsion, extending its service life, and ensuring the safety and stability of the container 10 during use.

[0101] Optionally, the thickness of the threshold body 110 is 3mm to 5mm. Optionally, the thickness of the threshold body 110 is 3mm, 4mm, or 5mm. As mentioned above, the threshold body 110, bottom folded edge 120, side folded edge 130, top folded edge 140, and flange 150 are integrally formed, that is, the thickness of the bottom folded edge 120, side folded edge 130, top folded edge 140, and flange 150 is all 3mm to 5mm.

[0102] Optionally, the length of the side fold 130 is less than the distance between the bottom fold 120 and the top fold 140. This arrangement creates a notch 131 between the top fold 140 and the side fold 130. The notch 131 is designed to accommodate the processing requirements of the bending machine, avoid the bending machine cutter head, ensure smooth bending operations, and improve production efficiency and processing quality.

[0103] As mentioned above, container 10 can be fitted with openable doors at any position on the side panels and end panels according to usage requirements. In this solution, in addition to the first door 510, other doors are also provided, which will be described in detail below.

[0104] The container 10 has a second door 520 on its side wall extending along its length direction DL. Specifically, an opening is formed on the side panel, and the second door 520 is provided at the opening. Along the height direction DH of the container 10, the length of the second door 520 is greater than the length of the first door 510.

[0105] Optionally, refer to Figure 7 and Figure 10The second door 520 and the first door 510 are located on opposite side walls of the container 10 along its width direction DW, respectively. That is, the second door 520 and the first door 510 are positioned opposite each other and spaced apart along the width direction DW of the container 10. The hydrogen production process may release hydrogen gas (flammable and explosive, with a density lower than air). The placement of the first door 510 and the second door 520 can accelerate the discharge of hydrogen gas through natural convection, preventing accumulation. Simultaneously, the first door 510 and the second door 520 can be provided with corresponding side passages. During equipment installation, maintenance, or replacement, these side passages can prevent tools / parts from having to detour, shortening operation time. For example, one side can be used for main equipment maintenance, and the other side for pipeline or electrical system inspection.

[0106] Optionally, refer to Figure 1 , Figure 2 , Figure 7 and Figure 10 The second door 520 is adjacent to the first door 510 along the length direction DL of the container 10. In this embodiment, the two second doors 520 are arranged opposite each other and spaced apart along the width direction DW of the container 10. The technical effect of the two second doors 520 being arranged opposite each other is similar to that of the first door 510 and the second door 520 being arranged opposite each other, and will not be described again here.

[0107] Since hydrogen production equipment is mostly modular skid-mounted, facilitating rapid deployment and installation, multiple doors are provided on the side of container 10 to allow the skid-mounted equipment to be moved into the container as a whole using a forklift. According to this plan, container 10 can accommodate hydrogen production equipment with a maximum capacity of 200 PEM.

[0108] Reference Figure 1 , Figures 8 to 10 Each of the two side walls of container 10 extending along its width direction DW is provided with a third door 530. Specifically, the end plate forms an opening, and the third door 530 is provided at the opening. The two third doors 530 are arranged opposite each other and spaced apart along the length direction DL of container 10. The heat dissipation effect of the two third doors 530 being arranged opposite each other is similar to the effect of the first door 510 and the second door 520 being arranged opposite each other, and will not be described in detail here.

[0109] Alternatively, this solution utilizes a standard 40-foot container (10-foot) structure. Combined with multiple side doors, it allows for the installation of extra-wide equipment. Because it uses the standard 10-foot container dimensions, minor design modifications are required before it can be shipped overseas.

[0110] The first door 510, the second door 520, and the third door 530 all include a door body 501, and each door body 501 is configured as a double door. That is, the first door 510, the second door 520, and the third door 530 are all configured as double doors. The double-door door body 501 is lighter and smaller in area than the single-door door body 501, and it is also easier to disassemble, replace, or repair.

[0111] Optionally, each door 501 is equipped with a locking structure, which includes a locking rod 502 and a locking seat 503. The locking rod 502 is located on the outside of the door 501. As mentioned above, the locking seats 503 of the first door 510 are respectively located on the top frame 300 and the threshold 100. The locking seats 503 of the second door 520 and the third door 530 are respectively located on the top frame 300 and the bottom frame 200. When the door 501 is closed, the locking rod 502 can be inserted into the locking seat 503 to reliably lock the door 501. Optionally, the locking seat 503 is welded to the top frame 300, the locking seat 503 is fixedly connected to the threshold 100, and the locking seat 503 is fixedly connected to the bottom frame 200 by fasteners.

[0112] To further enhance ventilation, door 501 may optionally be equipped with louvers. Optionally, the louvers may be detachable. The louvers are made of aluminum alloy. The louvers have an IP54 waterproof rating.

[0113] Optionally, the louvers include upper louvers 504 and lower louvers 505 spaced apart along the height direction DH of the container 10. Optionally, the upper louvers 504 are air outlet louvers; the lower louvers 505 are air inlet louvers. Optionally, since the door body 501 of the first container door 510 has a smaller dimension along the height direction DH, only the upper louvers 504 are provided.

[0114] Reference Figure 10 The container 10 is equipped with a partition 600, which divides the internal space of the container 10 into a first cavity 601 and a second cavity 602. The first cavity 601 is used to install electrical equipment such as rectifier cabinets and electrical cabinets, while the second cavity 602 is used to install hydrogen production equipment such as electrolyzers and purification devices. Optionally, the partition 600 is made of steel plate with a thickness of 8mm to 12mm. Optionally, both the first cavity 601 and the second cavity 602 are equipped with doors.

[0115] Optionally, the threshold 100 is located in the second cavity 602.

[0116] The top plate 700 of container 10, located above the second cavity 602, includes multiple sub-plates 710. The sub-plates 710 are detachably connected to each other and to the top frame 300. The sub-plates 710 facilitate the placement of hydrogen production equipment into the container from the top using a top-mounted method. When the equipment needs replacement or maintenance, the sub-plates 710 can be removed without disassembling the side walls. Understandably, a non-removable top plate 700 can also be provided on the top of container 10. The non-removable top plate 700 and the detachable sub-plates 710 can be combined to adapt to different usage scenarios.

[0117] Optionally, the sub-plate 710 is constructed as a flat plate. The flat sub-plate 710 uses a corrugated plate. The flat sub-plate 710 is simple and regular.

[0118] Reference Figure 1 and Figure 6 Optionally, multiple sub-panels 710 are arranged along the length DL of the container 10, with adjacent sub-panels 710 either continuously or spaced apart. This means the top of the container 10 is divided into multiple independent, detachable modules, such as three sub-panels 710. The individual sub-panels 710 are smaller and lighter, making them easier to transport and handle, and allowing for partial disassembly, avoiding the operational complexities of fully opening the top. When equipment needs replacement or repair, the sub-panels 710 can be partially disassembled (e.g., removing only the sub-panel 710 above the faulty component) without fully opening the top or disassembling the sidewalls.

[0119] Reference Figure 11 The top panel 700 has multiple mounting openings 701 for installing ventilation equipment 800. Optionally, the mounting openings 701 are formed in the sub-panel 710. Optionally, the ventilation equipment 800 includes, but is not limited to, axial flow fans, non-powered fans, air filters, etc. The installation of the mounting openings 701 facilitates the installation of the ventilation equipment 800, which can effectively exhaust hot air, harmful gases, or odors from inside the container 10. By installing different types of ventilation equipment 800, the airflow direction and speed can be flexibly adjusted.

[0120] Optionally, the base frame 200 is provided with a forklift slot 900 and / or a lifting connector 910.

[0121] The forklift slot 900 provides a stable insertion point for the forklift, enabling the container 10 to be transported short distances by forklift.

[0122] The lifting connector 910 provides a reliable connection point for lifting equipment, enabling the container 10 to be lifted and moved by the lifting equipment. Optionally, the lifting connector 910 is extendable and retractable along the width direction DW of the container 10. This extendable and retractable design allows for adaptation to different lifting equipment.
