In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.

[0039] Generally, the electrolytic cell comprises a cell body, two end plates, a plurality of pole plates and a plurality of tie rods, the two end plates are respectively arranged at the opposite sides of the cell body, the plurality of pole plates are arranged in the cell body in the axial direction of the cell body and separate the cell body to form a plurality of electrolytic chambers, and the plurality of tie rods are distributed in the circumferential direction of the cell body and are arranged through the cell body, the end plates and the pole plates to connect the cell body, the end plates and the pole plates together. In the related art, a plurality of support points are arranged on the lower side of one tie rod located at the bottom of the electrolytic cell to support the electrolytic cell as a whole, but this support mode cannot meet the support requirements of the electrolytic chambers with a large number and large mass, and the pole plates of the electrolytic chambers in the electrolytic cell are prone to slip and drop due to their own gravity. Especially under off-grid conditions, the randomness, intermittence and volatility of wind-solar power generation will cause the electrolytic cell to frequently start, stop and fluctuate in load during use, and the cell body will frequently expand and contract with the continuous change of the operating state, resulting in continuously changing internal stress in the electrolytic cell, thereby reducing the sealing performance of the entire electrolytic cell, increasing the risk of electrolytic cell leakage and reducing the service life of the electrolytic cell.

[0040] Therefore, as shown in Figures 1 to 5 The utility model provides a flexible support device 100 for supporting an electrolytic cell 200, which can achieve good support of the electrolytic cell 200 and prevent the electrolytic chambers in the electrolytic cell 200 from slipping and dropping due to their own gravity.

[0041] As shown in Figure 1 and Figure 2 The flexible support device 100 comprises a support seat 10, an insulating support assembly 20 and a driving assembly 30. The insulating support assembly 20 is arranged on the upper side of the support seat 10, and the insulating support assembly 20 comprises an insulating support beam 21 arranged in the axial direction of the electrolytic cell 200, which is used to support the bottom of the electrolytic cell 200. The driving assembly 30 comprises a plurality of driving members 31 distributed in the length direction X of the insulating support beam 21, each driving member 31 is connected to the support seat 10 and connected to the insulating support assembly 20, and the driving member 31 is used to drive the insulating support assembly 20 to ascend and descend. The length direction X of the insulating support beam 21 is parallel to the axial direction of the electrolytic cell 200.

[0042] In the embodiment of the utility model, first, the insulating support beam 21 is arranged to support the bottom of the electrolytic cell 200, and the insulating support beam 21 is arranged along the axial direction of the electrolytic cell 200, so that the insulating support beam 21 can form an abutting surface with a certain length with the bottom of the electrolytic cell 200 along the axial direction of the electrolytic cell 200, and support the plurality of electrolytic chambers in the electrolytic cell 200, the insulating support beam 21 is opposite to the plurality of electrolytic chambers in the vertical direction, so that the plurality of electrolytic chambers can be well supported, thereby realizing good support of the electrolytic cell 200, preventing the electrolytic chambers in the electrolytic cell 200 from sliding and falling due to their own gravity, and being beneficial to ensuring the structural stability of the electrolytic cell 200; second, the driving assembly 30 is arranged to drive the insulating support beam 21 to ascend and descend, so that the insulating support beam 21 can adjust the ascending and descending height according to the gap between the bottoms of different electrolytic cells 200, abut against the bottom of the electrolytic cell 200 and support the electrolytic cell 200, and the ascending and descending height of the output end of the driving part 31 can be controlled to adjust the support force of the electrolytic cell 200 during use, thereby realizing flexible support of the electrolytic cell 200, and the plurality of driving parts 31 in the driving assembly 30 are spaced apart along the axial direction of the electrolytic cell 200, so that the insulating support beam 21 can be well supported, and the stress concentration of the single driving part 31 is avoided.

[0043] Please combine Figure 3 In some embodiments, the side, away from the support base 10, of the insulating support beam 21 is provided with an arc-shaped first support surface 211, and the first support surface 211 is used to abut against the bottom of the electrolytic cell 200. By designing the first support surface 211 as arc-shaped, the first support surface 211 can be matched with the shape of the pull rod 204 located at the bottom of the electrolytic cell 200, so that the first support surface 211 can be attached to the outer side wall of the pull rod 204 along the circumferential direction of the pull rod 204, increase the contact area between the insulating support beam 21 and the electrolytic cell 200, make the pressure distribution of the electrolytic cell 200 on the insulating support beam 21 more uniform, and make the electrolytic cell 200 bear stress better, and the arc-shaped first support surface 211 can limit the movement of the electrolytic cell 200 along the radial direction of the pull rod 204 and parallel to the horizontal plane to a certain extent.

[0044] In some embodiments, the side, away from the support base 10, of the insulating support beam 21 defines a through groove 212. When the insulating support beam 21 supports the electrolytic cell 200, the through groove 212 is located at the bottom of the electrolytic cell 200, so that when the electrolytic cell 200 leaks electrolyte during operation, the leaked electrolyte can enter the through groove 212 and flow out through the through groove 212, thereby avoiding the accumulation of electrolyte at the bottom of the electrolytic cell 200 and causing the end of the electrolytic cell 200.

[0045] Specifically, the through groove 212 is located at the top of the insulating support beam 21, and the through groove 212 extends from one end face along the length direction X of the insulating support beam 21 to the other end face along the length direction X of the insulating support beam 21.

[0046] In some embodiments, the cross-section of the through groove 212 perpendicular to its own length direction X is V-shaped.

[0047] Typically, the insulating support beam 21 is a rigid body. If, during long-term use, the drive component 31 directly abuts against the insulating support beam 21, it may cause structural damage to the contact area between the drive component 31 and the insulating support beam 21. Figure 1 and Figure 2 As shown, in some embodiments, the insulating support assembly 20 further includes an insulating pad 22, which is connected to a plurality of drive members 31. An insulating support beam 21 is connected to the side of the insulating pad 22 facing away from the support base 10. By providing the insulating pad 22 between the drive members 31 and the insulating support beam 21, flexible contact between the drive members 31 and the insulating support beam 21 can be achieved, avoiding direct hard contact between the drive members 31 and the insulating support beam 21, which could lead to structural damage to the contact portion.

[0048] In some embodiments, the insulating support beam 21 is made of a rigid insulating material, and the insulating pad 22 is made of a flexible insulating material. The material of the insulating support beam 21 includes, but is not limited to, epoxy resin, polyketide-imide, ceramic, and polyetheretherketone.

[0049] like Figure 3 As shown, in some embodiments, one of the insulating support beam 21 and the insulating pad 22 is provided with a limiting protrusion, and the other of the insulating support beam 21 and the insulating pad 22 defines a limiting groove 221. The limiting protrusion is inserted into the limiting groove 221 to achieve a limiting fit between the insulating support beam 21 and the insulating pad 22.

[0050] In some embodiments, the limiting protrusion is a dovetail block, which is disposed at the bottom of the insulating support beam 21 along the length direction X; the limiting groove 221 is a dovetail groove, which is disposed at the top of the insulating pad 22 along the length direction X. The dovetail block and the dovetail groove are adapted to each other, and the dovetail block is inserted into the dovetail groove. In this way, the movement of the insulating support beam 21 relative to the insulating pad 22 in a direction perpendicular to its length direction X can be restricted.

[0051] The length direction X of the insulating support beam 21 is perpendicular to the length direction X of the insulating pad 22. The dovetail block extends from one end face of the insulating support beam 21 in the length direction X to the other end face of the insulating support beam 21 in the length direction X. The dovetail groove extends from one end face of the insulating pad 22 in the length direction X to the other end face of the insulating pad 22 in the length direction X.

[0052] In some other embodiments, dovetail blocks can also be arranged on the top of the insulating pad 22, and corresponding dovetail grooves can be arranged on the bottom of the insulating support beam 21.

[0053] In some embodiments, the insulating support assembly 20 further comprises fixing members 23, which are fixedly connected to the insulating support beam 21 and the insulating pad 22, so as to completely limit the insulating support beam 21 on the insulating pad 22.

[0054] In some embodiments, the bottom of the fixing member 23 is also provided with a dovetail block, which is the same as the dovetail block on the bottom of the insulating support beam 21.

[0055] In some embodiments, the number of the fixing members 23 is two, and the two fixing members 23 are respectively arranged on the two end faces of the insulating support beam 21 in the length direction X, and the two fixing members 23 are respectively fixed to the insulating pad 22. In this way, the two fixing members 23 can limit the movement of the insulating support beam 21 along its length direction X relative to the pad. In combination with the limiting cooperation of the dovetail blocks and the dovetail grooves (limiting the movement of the insulating support beam 21 relative to the insulating pad 22 in the direction perpendicular to the length direction X of the insulating support beam 21), the insulating support beam 21 can be completely limited on the insulating pad 22, thereby ensuring the stability of the connection between the insulating support beam 21 and the insulating pad 22.

[0056] In the specific implementation process, the fixing member 23 can be fixed to the insulating pad 22 by screws.

[0057] Of course, in some other embodiments, the insulating support beam 21 can also be fixed to the insulating pad 22 by other means, for example, directly fixed by screws (which needs to avoid direct contact between the screws and the electrolytic cell 200), or for example, a limiting column is arranged in one of the insulating support beam 21 and the insulating pad 22, and a limiting hole is arranged in the other one of the insulating support beam 21 and the insulating pad 22, and the limiting column is inserted into the limiting hole, so as to limit the insulating support beam 21 in the horizontal direction.

[0058] In some embodiments, the flexible support device 100 further comprises a guide assembly 40, which is connected to the support seat 10 and the insulating support assembly 20, and the guide assembly 40 is used to guide the insulating support assembly 20 to move up and down in the vertical direction.

[0059] In some embodiments, the guiding assembly 40 comprises a guiding part 41 and a guiding rod 42, the guiding part 41 is connected with one of the insulating support assembly 20 and the support base 10, the guiding rod 42 is connected with the other one of the insulating support assembly 20 and the support base 10, the guiding part 41 defines a guiding groove, and the guiding rod 42 is inserted into the guiding groove. During the lifting of the insulating support assembly 20, the insulating support assembly 20 can be guided to lift along the vertical direction by the cooperation between the guiding rod 42 and the guiding groove of the guiding part 41, so as to avoid deviation.

[0060] It can be understood that the electrolytic cell 200 generates electrolysis reactions in each electrolytic cell and releases a large amount of heat during operation. Based on the principle of thermal expansion and contraction, the electrolytic cell 200 will generate internal stress and deform after being heated, causing the end plate of the electrolytic cell 200 to have a tendency to move along the axial direction of the electrolytic cell 200 relative to the base 11. At this time, if the entire electrolytic cell 200 is directly fixed on the base 11, the deformation and internal stress generated by the electrolytic cell 200 will not be released, which can easily cause the end plate of the electrolytic cell 200 to be bent and deformed, and can also damage the sealing performance of the electrolytic cell 200. As shown in Figure 1 and Figure 2 In some embodiments, the support base 10 comprises a base 11, a first support foot 12 and a second support foot 13, the first support foot 12 and the second support foot 13 are respectively connected to the two ends of the base 11, the first support foot 12 is used to support the first end plate 202 of the electrolytic cell 200 and is fixedly connected with the first end plate 202, and the second support foot 13 is used to support the second end plate 203 of the electrolytic cell 200 and is slidably connected with the second end plate 203. Through the above arrangement, while achieving the support effect of the first end plate 202 and the second end plate 203 of the electrolytic cell 200, the second end plate 203 can slide along the axial direction of the electrolytic cell 200 through the second support foot 13 to adapt to the axial size change of the electrolytic cell 200 caused by thermal expansion and contraction during operation, so that the deformation and internal stress generated by the electrolytic cell 200 can be released, and the end plate of the electrolytic cell 200 can be prevented from being bent and deformed and the sealing performance of the electrolytic cell 200 can be prevented from being damaged, thereby reducing the risk of electrolyte leakage of the electrolytic cell 200 and prolonging the service life of the electrolytic cell 200.

[0061] In some embodiments, the first support base 12 is provided with a first side plate 121 and a second support surface 122, the second support surface 122 is used to support the first end plate 202, and the first side plate 121 is used to abut and fixedly connect with one side of the first end plate 202, so that the first side plate 121 can bear the axial force of the electrolytic cell 200 on one side of the electrolytic cell 200. The second support base 13 is provided with two spaced second side plates 131 and a third support surface 132 located between the two second side plates 131, the third support surface 132 is used to support the second end plate 203, and the two second side plates 131 are respectively used to limit the movement of the second end plate 203 on the opposite sides of the second end plate 203, so that the second end plate 203 can only slide between the two second side plates 131, avoiding that the sliding distance of the second end plate 203 is too large.

[0062] In the specific implementation process, the first side plate 121 and the first end plate 202 can be fixedly connected through a first bolt and a first nut, specifically, the shank part of the first bolt is arranged through the first side plate 121 and the first end plate 202, the nut of the first bolt is located on the side of the first side plate 121 away from the first end plate 202, and the first nut is threadedly connected with the shank of the first bolt and located on the side of the first end plate 202 away from the first side plate 121; the second side plate 131 and the second end plate 203 can be slidably connected through a second bolt and a second nut, specifically, the shank part of the second bolt is arranged through the two second side plates 131 and the second end plate 203, the nut of the second bolt is located on the side of one of the two second side plates 131 away from the second end plate 203, and the second nut is threadedly connected with the shank of the second bolt and located on the side of the other of the two second side plates 131 away from the second side plate 131, so that the second end plate 203 can slide along the axial direction of the second bolt between the two second side plates 131.

[0063] In some embodiments, the second support surface 122 and the third support surface 132 are both arc-shaped, so that the second support surface 122 and the third support surface 132 can respectively match the shape of the first end plate 202 and the second end plate 203 of the electrolytic cell 200, so that the second support surface 122 can be attached to the outer side wall of the first end plate 202 along the circumferential direction of the first end plate 202, and the third support surface 132 can be attached to the outer side wall of the second end plate 203 along the circumferential direction of the second end plate 203, thereby increasing the contact area of the second support surface 122 with the first end plate 202 and the contact area of the third support surface 132 with the second end plate 203, so that the pressure distribution of the first end plate 202 and the second end plate 203 on the second support surface 122 and the third support surface 132 respectively is more uniform, and the force is better, and the arc-shaped second support surface 122 and the third support surface 132 can respectively limit the movement of the first end plate 202 and the second end plate 203 along the radial direction thereof and parallel to the horizontal plane to a certain extent.

[0064] It can be understood that the structure of the base 11 can be set according to actual needs, and the specific structure of the base 11 is not limited in the utility model, for example, the base 11 can be composed of two spaced apart cross beams and a plurality of spaced apart longitudinal beams located between the two cross beams to form a frame structure, wherein the two ends of each longitudinal beam are connected to two cross beams.

[0065] In some embodiments, the driving member 31 is an electric lifting mechanism, which can smoothly drive the insulation support assembly 20 to lift to achieve flexible support of the electrolytic cell 200, for example, a miniature hydraulic lifting mechanism, which can bear a large load and provide a high output force.

[0066] In other embodiments, the driving member 31 can also be other mechanisms for driving the insulation support assembly 20 to lift, for example, an electric push rod, etc.

[0067] As shown in Figure 4 and Figure 5 The utility model embodiment further provides a water electrolysis hydrogen production equipment 1000, the water electrolysis hydrogen production equipment 1000 includes electrolytic cell 200 and the flexible support device 100 as described above, and the flexible support device 100 supports electrolytic cell 200.
