[0050] The utility model provides a hydrogen production container.

[0051] Now, exemplary embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

[0052] like Figure 1 As shown, the hydrogen production container 100 provided by the present invention includes an electrolytic cell 10 and a base frame 20. The electrolytic cell 10 is disposed in the box body of the hydrogen production container 100, and a support leg 11 is disposed at the bottom of the electrolytic cell 10. The electrolytic cell 10 is placed on the base frame 20 through its support leg 11. Figure 2 As shown, the bottom frame 20 includes a bottom side beam 21 and an H-shaped steel 23. The two parallel bottom side beams 21 extend along the length direction D1 of the box body, and the bottom side beams 21 are provided with a lifting connection device 22 that is retractable along the width direction D2 of the box body. The lifting connection device 22 is used to connect the lifting equipment to lift the hydrogen production container 100. The H-shaped steel 23 is connected to the two bottom side beams 21 along the width direction D2 of the box body and is located below the support leg 11 of the electrolyzer 10. Among them, at least part of the lifting connection device 22 and the H-shaped steel 23 are correspondingly arranged along the width direction D2 of the box body, that is, at least part of the lifting connection device 22 and the H-shaped steel 23 are aligned in the width direction D2 of the box body.

[0053] According to the hydrogen production container 100 of the utility model, a large-mass electrolyzer 10 is arranged inside the box body. During the hoisting and transportation of the hydrogen production container 100, higher requirements are placed on the structural strength of the base frame 20, especially the crossbeam located below the support leg 11. The H-shaped steel structure has a stronger pressure-bearing capacity than the ordinary bottom crossbeam structure. The base frame 20 is provided with an H-shaped steel 23, and the H-shaped steel 23 is located below the support leg 11 of the electrolyzer 10, which can enhance the structural strength below the support leg 11 and even the overall structural strength of the base frame 20. Therefore, the hydrogen production container 100 of the utility model can prevent the base frame 20 from being deformed due to the large-mass electrolyzer 10, especially during the hoisting and transportation of the hydrogen production container 100. In addition, the hoisting connection device 22 is arranged on the bottom crossbeam 21, and hoisting is performed from the bottom of the hydrogen production container 100, which will not make excessive requirements on the top structural strength of the hydrogen production container 100, and the hoisting process is safer. The lifting connection device 22 and the H-shaped steel 23 are correspondingly arranged along the width direction D2 of the box body, which can prevent other parts of the base frame 20 from being subjected to excessive pressure.

[0054] In the illustrated embodiment, the electrolytic cell 10 is provided with four legs 11, specifically, two legs are provided at each end of the electrolytic cell 10. In other embodiments, the electrolytic cell 10 may also be provided with more legs 11, such as 5 legs 11, or 6 legs 11. H-shaped steel is provided under at least some of the legs 11, or H-shaped steel is provided under all of the legs 11. For example, the electrolytic cell 10 is provided with 6 legs 11, which are respectively provided at three positions along the length direction D1 of the box body, and H-shaped steel is provided under at least one position where the legs 11 are located. For example, H-shaped steel is provided under all three positions where the legs 11 are located.

[0055] like Figure 2 and Figure 3As shown, in a preferred embodiment, along the length direction D1 of the box body, at least two H-shaped steels 23 are arranged below the legs 11 at the same end of the electrolytic cell 10, and at least two H-shaped steels 23 are arranged side by side along the length direction D1 of the box body, which can further enhance the structural strength below the legs 11. In addition, the H-shaped steel 23 has a larger load-bearing range on the upper surface of the base frame 20, for example, it is larger than the size of the legs 11 in the length direction D1 of the box body.

[0056] like Figure 4 As shown, the hoisting connection device 22 includes a sleeve 221 and a connecting rod 222. The bottom side beam 21 has a through hole extending along the width direction D2 of the box body, and the sleeve 221 is arranged in the through hole and fixedly connected to the bottom side beam 21. The connecting rod 222 can be movably inserted into the sleeve 221 along the width direction D2 of the box body. The length of the connecting rod 222 is greater than the sleeve 221, and both ends have flanges with a size greater than the inner diameter of the sleeve 221. Therefore, the connecting rod 222 can move in the sleeve 221 along the axial direction of the sleeve 221 without being separated from the sleeve 221. When the hoisting connection device 22 is used to connect the hoisting equipment, the connecting rod 222 moves outward and extends out of the bottom side beam 21, so that the hoisting equipment is connected to the connecting rod 222. In the non-use state of the hoisting connection device 22, the connecting rod 222 moves inward until the outer flange abuts against the sleeve 221, so that the connecting rod 222 is hidden in the bottom frame 20 to avoid external collision. Here, “inside” refers to the direction toward the central axis of the base frame 20 , and “outside” refers to the direction away from the central axis of the base frame 20 .

[0057] In the illustrated embodiment, four lifting connection devices 22 are provided on each side of the bottom beam 21. In other embodiments, the number of the lifting connection devices 22 may be more or less.

[0058] like Figure 5 As shown, the hydrogen production container 100 further includes a top cover 30, which is detachably connected to the box body, and is provided with a hook 31, which is used to lift the top cover 30. Thus, the electrolyzer 10 can be lifted into the box body from the top, making the installation of the electrolyzer 10 more convenient.

[0059] Preferably, at least a portion of the side plates, end plates, bottom plate and top plate of the top cover 30 of the box body is provided with a heat-insulating layer, which is beneficial to maintaining the temperature inside the box body.

[0060] Preferably, at least one of the two side surfaces and the two end surfaces of the box body is provided with a shutter 50 for ventilation. Further preferably, the top cover 30 is provided with a fan 32 .

[0061] Preferably, at least one side of the box body has a side door 40 to facilitate entry and exit of personnel and equipment.

[0062] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein are only for describing specific implementation purposes and are not intended to limit the present invention. The features described herein in one embodiment may be applied to another embodiment alone or in combination with other features, unless the feature is not applicable or otherwise specified in the other embodiment.

[0063] The present invention has been described through the above-mentioned embodiments, but it should be understood that the above-mentioned embodiments are only for the purpose of example and explanation, and the present invention is not limited to the above-mentioned embodiments. According to the teachings of the present invention, more variations and modifications can be made, and these variations and modifications all fall within the scope of protection required by the present invention.
