[0043] Reference Figures 1 to 4 , several embodiments of the container and hydrogen production system of the utility model are given below.

[0044] like Figures 1 to 4 As shown, the container 100 of the embodiment of the utility model includes a container body 200 , a container door 300 , a locking assembly 500 and a support column 400 .

[0045] It can be understood that the box body 200 is hollow and has a mounting cavity 210 for mounting the hydrogen production equipment. Figure 4 The box body 200 is arranged along the long end side opening 220 of the installation cavity 210, as shown in FIG. Figure 1 As shown, the box body 200 has an opening 220 on the side, and multiple skids constituting the hydrogen production equipment are loaded and unloaded into the installation cavity 210 through the opening 220. The multiple skids are laid along the long end spacing of the installation cavity 210 and connected in sequence, thereby realizing a high degree of integration of the hydrogen production equipment.

[0046] In some embodiments, the hydrogen production equipment can be hoisted by a crane.

[0047] In other embodiments, the hydrogen production equipment can be loaded and unloaded by a forklift.

[0048] With such arrangement, when installing the hydrogen production equipment in the container 100, a crane or a forklift can be directly used for quick loading and unloading, thus saving the manpower, time and cost required for installation, and the positions of the multiple skids in the installation cavity 210 can be adjusted by a crane, a forklift and other lifting equipment, so as to arrange the hydrogen production skids in an orderly manner. Furthermore, when a skid constituting the hydrogen production equipment fails, a worker can directly use a crane or a forklift to independently unload the failed skid through the opening 220, and quickly replace the failed skid, without having to remove part of the skid before removing the failed skid.

[0049] It is understandable that the door 300 and the box body 200 are movably connected so that the opening 220 of the box body 200 is covered and the hydrogen production equipment is enclosed in the installation cavity 210, or the opening 220 of the box body 200 is exposed, which is convenient for workers to load and unload the hydrogen production equipment. The door 300 is fixed to the box body 200 through the locking assembly 500, so that the container 100 is in a stable closed state to prevent outsiders from entering the installation cavity 210.

[0050] It is understandable that since the opening 220 is arranged along the long end side of the installation cavity 210, the supporting strength of the box 200 at the opening 220 will decrease, and the upper end of the box 200 will easily collapse downward, affecting the overall structure of the box 200 and the skid placed inside it.

[0051] In this regard, a plurality of support columns 400 are disposed in the box body 200, and the plurality of support columns 400 are disposed at intervals along the long end of the installation cavity 210 at the opening 220, such as Figure 4 As shown, the upper end of the support column 400 is connected to the inner upper end of the box body 200, and the lower end of the support column 400 is connected to the inner lower end of the box body 200, thereby firmly supporting the box body 200, improving the structural strength of the box body 200, and allowing the container 100 to install hydrogen production equipment with a larger weight or a higher height.

[0052] In this embodiment, the box body 200 is a cubic structure, the installation cavity 210 corresponds to a cubic cavity, the long end of the installation cavity 210 extends in the left-right direction, the opening 220 of the box body 200 is arranged forward, and the hydrogen production equipment can be installed in the installation cavity 210 from front to back. Figure 1 shown.

[0053] In some embodiments, one end of the door 300 along the vertical direction is hinged to the box body 200. Specifically, one end of the door 300 along the vertical direction is hinged to the upper end or the lower end of the box body 200, so that the door 300 rotates relative to the box body 200 along the axis in the left-right direction, thereby realizing the rotation opening and closing of the door 300 relative to the box body 200. At this time, the locking assembly 500 is provided at the box body 200 and the other end of the door 300. When the door 300 rotates and closes relative to the box body 200, the other end of the door 300 along the vertical direction is fixed to the box body 200 through the locking assembly 500.

[0054] It is understandable that, since the upper or lower end of the box door 300 is hinged to the box body 200, the box door 300 that is rotated downward to close or rotated downward to open will collide with the edge of the box body 200 and the multiple support columns 400 or the ground due to gravity, and the vibration generated by the collision is likely to affect the multiple skids and their connection structures in the box body 200. In addition, it is difficult for workers to push up the box door 300 to rotate the box door 300 upward to open or close it.

[0055] In this regard, the box body 200 is connected to a driving component, and the output end of the driving component is connected to the box door 300. When the box door 300 is opened or closed relative to the box body 200, the worker can start the driving component to automatically open or close the box door 300.

[0056] It is understandable that the driving assembly can be a rotary motor, a pneumatic rod, etc.

[0057] In other embodiments, one end of the box door 300 along the horizontal direction is hinged to the box body 200. Specifically, since the box door 300 covers the opening 220 on the front side of the box body 200, one end of the box body 200 along the left-right direction is hinged to the left end or the right end of the box body 200, so that the box door 300 rotates relative to the box body 200 along the axis in the vertical direction, thereby realizing the rotation switch of the box door 300 relative to the box body 200. At this time, the locking assembly 500 is provided at the box body 200 and the other end of the box door 300. When the box door 300 rotates to cover the opening 220, the other end of the box door 300 along the horizontal direction is fixed to the box body 200 through the locking assembly 500.

[0058] It is understandable that workers can manually turn and open the box door 300; or they can use a drive component to automatically open or close the box door 300 using electric or pneumatic means to reduce labor costs.

[0059] In this embodiment, the door 300 is provided with a hanging ear 311, and the hanging rope 600 is passed through the hanging ear 311. Figure 1 As shown, workers can lift the lifting rope 600 through lifting equipment to load and unload the box door 300 to cover or reveal the opening 220.

[0060] It is understandable that there are multiple locking assemblies 500, and the box door 300 and the box body 200 are detachably connected through multiple locking assemblies 500. Specifically, the box door 300 is embedded in the opening 220 of the box body 200, and the multiple support columns 400 are used to limit the embedding depth of the box door 300 to ensure that the outer surface of the box door 300 and the outer surface of the box body 200 are in the same vertical plane.

[0061] It can be understood that the upper end of the locking assembly 500 is used to connect the upper end of the box door 300 and the upper end of the box body 200, and the lower end of the locking assembly 500 is used to connect the lower end of the box door 300 and the lower end of the box body 200. Multiple locking assemblies 500 are arranged at intervals along the long end of the installation cavity 210, that is, multiple locking assemblies 500 are arranged at intervals along the left-right direction, so that the box door 300 and the box body 200 are multiple and firmly connected along the left-right direction.

[0062] In this embodiment, eight locking assemblies 500 are provided between the door 300 and the housing 200 and are spaced apart in the left-right direction.

[0063] It is understandable that the door 300 includes a hanging ear column 310, and the hanging ear 311 is integrally formed and connected to the hanging ear column 310. Figure 2 and Figure 3As shown, the ear 311 is firmly connected to the door 300. Two ear posts 310 are provided and are spaced along the long end of the installation cavity 210, that is, the two ear posts 310 are spaced along the left and right directions. Each ear post 310 is provided with two ears 311, and the two ears 311 are spaced along the up and down directions.

[0064] In this way, before lifting the box door 300, one end of the lifting rope 600 passes through the two lifting ears 311 of the lifting ear column 310 from top to bottom and is tied and fixed to the lower lifting ear 311, and the other end of the lifting rope 600 passes through the two lifting ears 311 of another lifting ear column 310 from top to bottom and is tied and fixed to the lower lifting ear 311, and the output end of the lifting equipment is hooked with the middle part of the lifting rope 600, so as to stably lift the box door 300, as shown in FIG. Figure 1 shown.

[0065] It is understandable that the two lifting ears 310 are symmetrically arranged to keep the two ends of the lifted door 300 balanced, to avoid the lifted door 300 being heavy at one end and light at the other end, causing the door 300 to shift and affecting the installation of the door 300.

[0066] In this embodiment, the box body 200 includes a frame 230 and a plurality of box panels 240. Figure 4 shown.

[0067] It can be understood that the frame 230 forms a cubic structure. Specifically, the frame 230 includes four columns 231, four cross beams 232 and four longitudinal beams 233. The columns 231 extend in the up-down direction, the cross beams 232 extend in the left-right direction, and the longitudinal beams 233 extend in the front-back direction. The upper and lower ends of the columns 231 are respectively connected to the left or right ends of two cross beams 232 opposite to each other, and the front and rear ends of the longitudinal beams 233 are respectively connected to the left and right ends of two cross beams 232 opposite to each other, so as to form a cubic frame 230. Figure 4 shown.

[0068] It is understandable that the opening 220 is formed by two cross beams 232 and two upright posts 231 located in the front, and thus the door 300 is embedded between the two upright posts 231 and the two cross beams 232 .

[0069] It is understandable that the box plate 240 is connected to the inner side of the frame 230. Specifically, since the box body 200 is a cubic structure and the box door 300 is embedded in the front opening 220 of the box body 200, five box plates 240 are provided, and are respectively connected between the two horizontal beams 232 and the two vertical columns 231 at the rear, between the two vertical columns 231 and the two longitudinal beams 233 at the left and right, and between the two horizontal beams 232 and the two longitudinal beams 233 at the top and bottom.

[0070] It can be understood that the upper and lower ends of the support column 400 are connected to the inner sides of the two cross beams 232 located in the front by welding, and are welded and fixed to the upper box plate 240 and the lower box plate 240, which does not affect the opening 220 embedded in the box door 300 and also plays the role of supporting the frame 230.

[0071] It is understandable that the installation position of the support column 400 can be adjusted according to the size of the skid. For example, the distance between the support column 400 and the left box plate 240, the distance between the support column 400 and the right box plate 240, and the distance between two adjacent support columns 400 can be adjusted so that the position of the support column 400 does not affect the loading and unloading of multiple skids by the lifting equipment.

[0072] It is understandable that since the hydrogen production equipment is highly integrated and the space of the installation cavity 210 is small, after the hydrogen production equipment is installed in the installation cavity 210, the operator can only perform inspection and maintenance from one side of the skid, and the space is limited, making it difficult to achieve comprehensive inspection and maintenance.

[0073] In this embodiment, the box plate 240 horizontally opposite to the box door 300 is provided with a plurality of inspection doors 241, that is, the box plate 240 located at the rear is provided with a plurality of inspection doors 241. Figure 1 The multiple inspection doors 241 are arranged at intervals along the long end of the installation cavity 210, that is, the multiple inspection doors 241 are arranged at intervals along the left and right directions, so that each inspection door 241 can correspond to at least one skid, which is convenient for operators to inspect one of the skids.

[0074] Furthermore, when a faulty skid cannot be repaired after passing through the inspection door 241, the box door 300 can be lifted by a lifting device to inspect or remove the faulty skid.

[0075] It is understood that the frame 230 is provided with a plurality of vertically connected corner pieces, so that the opposite ends of the corner pieces are perpendicular to each other, and the opposite ends of the corner pieces can be respectively connected to the mutually connected columns 231 and beams 232, the columns 231 and longitudinal beams 233, and the longitudinal beams 233 and beams 232, so that the frame 230 is stably formed into a square frame 230. In this regard, 24 corner pieces are provided.

[0076] In this embodiment, one end of the corner piece is connected to the column 231, and the other end of the corner piece is connected to the beam 232, so as to realize the vertical connection of multiple columns 231 and multiple beams 232, ensure that the columns 231 and beams 232 located in the front form a stable rectangular opening 220, ensure the strength and rigidity of the box body 200 structure, and enable the columns 231 and beams 232 to stably support the box door 300 embedded in the opening 220. Therefore, 8 corner pieces are provided.

[0077] It can be understood that the box panels 240 located on the left and right are both double-door structures. Specifically, the double-door structure includes a first door panel 251 located in the front and a second door panel 252 located in the rear. The front end of the first door panel 251 and the column 231 located in the front are hinged along the axis in the vertical direction, and the rear end of the second door panel 252 and the column 231 located in the rear are hinged along the axis in the vertical direction, so that the two can be rotated and opened relative to the two columns 231 in front and behind, respectively. Figure 1 shown.

[0078] It is understandable that the outer surfaces of the first door panel 251 and the second door panel 252 are further provided with ventilation ports 253 which are symmetrical in front and back. The ventilation ports 253 extend left and right and communicate with the installation cavity 210. Figure 1 shown.

[0079] It is understandable that the first door panel 251 and the second door panel 252 are respectively provided with locking assemblies 500 to ensure that the first door panel 251 and the second door panel 252 are firmly connected to the longitudinal beam 233 and firmly maintained in a closed state, so that the installation cavity 210 is in a closed state to prevent outsiders from entering.

[0080] It can be understood that the locking assembly 500 is a conventional truck compartment door locking structure. Specifically, the locking assembly 500 includes a locking rod 510 and a lock seat 520. The locking rod 510 includes a lock handle, a lock head, a large rod clamp, a limit ring and a handle seat. The two ends of the lock handle are connected to the lock head. The large rod clamp is arranged on the lock head. The lock handle is rotatably mounted on the outer surface of the cross beam 232 or the longitudinal beam 233 through a plurality of limit rings. One end of the handle seat is fixedly connected to the box door 300 or the double door structure, and the other end of the handle seat is detachably connected to the lock handle. The lock seat 520 is fixedly connected to the cross beam 232 or the longitudinal beam 233.

[0081] With such arrangement, the operator can lock the lock head with the large rod clamp in the lock seat 520 by turning the handle seat, thereby locking the box door 300, the first door panel 251 or the second door panel 252 on the frame 230.

[0082] In this embodiment, a rubber strip and a rubber pad for sealing are further provided in the container 100 .

[0083] It is understandable that the connecting edges of the door 300 and the opening 220 are provided with rubber strips and rubber pads to prevent the produced hydrogen from leaking and being output to the outside of the container 100 through the gaps, causing a violent combustion reaction with sparks, smoke or open flames outside the container 100, creating the risk of explosion.

[0084] It is understandable that rubber strips and rubber pads are also provided between the double-door structure and the frame 230 to prevent gaps from forming when the first door panel 251 and the second door panel 252 are rotated to cover the left and right sides of the frame 230 .

[0085] It is understandable that the locking assembly 500 is also provided with rubber strips and rubber pads, so that the locking assembly 500 can press and seal the box door 300 and the double-door structure onto the frame 230 .

[0086] It is understandable that, since hydrogen production methods include hydrogen production from mineral fuels, hydrogen production from biomass, hydrogen production from other ammonia substances, etc., the corresponding hydrogen production equipment can be placed in the installation cavity 210.

[0087] In this embodiment, the hydrogen production method adopts water electrolysis to produce hydrogen, so the hydrogen production equipment is an electrolytic cell and its separation and purification skid, auxiliary facilities, etc., which are loaded through a 40-foot container 100. The hydrogen production equipment is divided into four skids, which are sequentially placed in the installation cavity 210 through the opening 220 opened at the front side.

[0088] The utility model also provides a hydrogen production system, including an electrolyzer and a container 100.

[0089] With such arrangement, the electrolytic cell can be installed into the installation cavity 210 through the open opening 220, thereby expanding the installation and maintenance space of the electrolytic cell and making it easier for workers to load and unload the electrolytic cell and its separation and purification skids, auxiliary facilities, etc., thereby reducing the labor, time and cost required for loading and unloading and simplifying the structure of the hydrogen production system.

[0090] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
