When the locking structure works, it can also replace the traditional gasket to compensate for the empty space between the nut 42 and the upper cover plate 11 / lower cover plate 12, thereby reducing the locking cycle of the entire electrolytic cell.

[0035] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the locking structure includes a compensation sleeve 33, a limit block 34, a cylinder 37, an inflation seat 35, a plug 40 and an elastic member. The compensation sleeve 33 is movably sleeved on the nut 42 and the two are elastically connected. The compensation sleeve 33 is arranged between the nut 42 and the upper cover plate 11 / lower cover plate 12. The inflation seat 35 is arranged on the nut 42 and is arranged opposite to the compensation sleeve 33. The plug 40 is movably arranged in the inflation seat 35 and the two are connected by an elastic member. The nut 42 is sleeved with a ring 36. The cylinder 37 is arranged on the ring 36 and is connected to the inflation seat 35 through a hose 38. The limit block 34 is arranged on the compensation sleeve 33. The upper cover plate 11 and the lower cover plate 12 are both provided with a limit groove 18 that matches the limit block 34. The movable end of the cylinder 37 is connected to the compensation sleeve 33.

[0036] In a specific case of the present embodiment, the docking structure includes a mounting seat 19, a docking column and a driving gear 15.

[0037] In another specific case in this embodiment, the driving structure also includes a stepper motor 9, a belt and a transmission wheel. The stepper motor 9 is provided on the upper base 2 and the lower base 1. The driving shaft 10 and the output end of the stepper motor 9 are provided with a transmission wheel, and the transmission wheels are connected by belts.

[0038] It should be noted that the elastic member in this embodiment can be a spring 41, a spring sheet or an elastic steel plate structure. In this embodiment, the elastic member is preferably a spring 41, and the spring 41 is connected between the inflation seat 35 and the plug 40. As for the specific model parameters of the spring 41, the best choice can be made according to actual conditions, and no specific limitation is made here.

[0039] When the assembly work among the bipolar plate 13, the separator 14, the positive and negative electrodes, the upper cover plate 11 and the lower cover plate 12 is completed, the stud 17 is passed through the column groove, and the nut 42 is installed at both ends of each stud 17. By controlling the failure of the support unit, the entire upper cover plate 11, the lower cover plate 12 and the intermediate components move downward under the action of their gravity. In the actual process, a damping can be set between the lower cover plate 12 and the lower base 1 to achieve the protection of the electrolytic cell, so that the slot 16 and the drive shaft 10 are docked, and the hydraulic cylinder 3 is controlled to contract to make the upper base 2 move downward, so that the drive shaft 10 on the upper base 2 and the slot 16 on the upper cover plate 11 are docked. At this time, the stepping motors 9 on the upper base 2 and the lower base 1 are controlled to be energized and rotated. Under the action of the transmission wheel and the belt, the drive shaft 10 is controlled to rotate, thereby driving the drive gear 15 to rotate, and the meshing between the drive gear 15 and the teeth 39 Under the cooperative action, the inflation seat 35 and the nut 42 can be controlled to rotate. At this time, through the cooperation between the limit block 34 and the limit groove 18, the cylinder 37, the compensation sleeve 33 and the ring 36 are controlled not to rotate, and then the nut 42 and the compensation sleeve 33 are controlled to move downward. In this process, the stud 17 and the plug 40 conflict with each other, driving the plug 40 to move upward relative to the inflation seat 35, thereby squeezing the air in the inflation seat 35 into the cylinder 37, driving the cylinder 37 to extend, so that the compensation sleeve 33 moves downward relative to the nut 42 and conflicts and locks with the upper cover plate 11 or the lower cover plate 12, thereby realizing the compensation of the empty space between the nut 42 and the upper cover plate 11 / lower cover plate 12, and getting rid of the traditional manual method of setting a number of gaskets for locking and compensation between the nut 42 and the upper cover plate 11 / lower cover plate 12 according to the use distance between the upper cover plate 11 and the lower cover plate 12 and the length of the stud 17.

[0040] See also Figure 1-Figure 5 As another preferred embodiment of the present application, the electrolytic cell body further includes a protective structure, the number of the protective structure and the number of the studs 17 are the same, and the protective structure is used to protect the studs 17.

[0041] In this exemplary embodiment, the protection structure includes a rack 23, a transmission gear 24, a protection main pipe 21 and two protection sub-pipes 22. The protection main pipe 21 is sleeved on the stud 17, and the two protection sub-pipes 22 are symmetrically and movably inserted at both ends of the protection main pipe 21. The transmission gear 24 is movably set on the protection main pipe 21, and each of the protection sub-pipes 22 is provided with a rack 23. The racks 23 are staggered relative to the transmission gear 24 and meshed with the transmission gear 24.

[0042] In actual application, the protection main pipe 21 and the protection sub-pipe 22 are both sleeved on the surface of the stud 17. When controlling the distance between the upper cover plate 11 and the lower cover plate 12, the protection sub-pipe 22 can be resisted, driving the protection sub-pipe 22 to move relative to the protection main pipe 21. Under the meshing action between the rack 23 and the transmission gear 24, the protection sub-pipes 22 on both sides of the protection main pipe 21 are controlled to move synchronously, thereby driving the displacement of the protection sub-pipe 22 to be consistent, thereby realizing the protection treatment of the studs 17 at different distances between the upper cover plate 11 and the lower cover plate 12.

[0043] See also Figure 1-Figure 6 As another preferred embodiment of the present application, a rubber head 20 is provided on both the air outlet and the liquid inlet, a plurality of through holes 26 are formed on the rubber head 20 on the air outlet, and a locking structure is provided between the rubber head 20 on the air outlet and the upper cover plate 11 / lower cover plate 12, for increasing the connection stability between the rubber head 20 and the upper cover plate 11 / lower cover plate 12 when the air outlet pressure increases.

[0044] In the present exemplary embodiment, the locking structure includes a support plate 25, a suction cup 27, a connecting seat 28, a cavity 32, a slide plate 31, a hollow tube 29 and a piston rod 30. The support plate 25 is sleeved on the rubber head 20. The cavity 32 is arranged in the support plate 25 and is connected to the through hole 26. There are several connecting seats 28 and they are symmetrically arranged on the support plate 25. Each of the connecting seats 28 is movably and elastically connected with a suction cup 27. The hollow tube 29 is arranged on the support plate 25 and is connected to the suction cup 27 through the connecting seat 28. The piston rod 30 is movably arranged in the hollow tube 29 and the two are elastically connected. The slide plate 31 is movably arranged in the cavity 32 and is connected to the piston rod 30.

[0045] In actual application, the locking structure is installed and fixed on the rubber head 20 on the air outlet. When the hydrogen or oxygen produced by water electrolysis is discharged through the rubber head 20, the hydrogen and oxygen will generate air pressure in the rubber head 20. According to the different strengths of the electrolyzed water, the air pressure value inside the rubber head 20 is different. When the air pressure value is large, part of the gas will enter the cavity 32 along the through hole 26, thereby controlling the movement of the slide plate 31, and then driving the piston rod 30 to move along the hollow tube 29. At this time, the air between the suction cup 27 and the upper cover plate 11 / lower cover plate 12 can be extracted to achieve a vacuum state, thereby improving the stable connection coefficient between the rubber head 20 on the air outlet and the upper cover plate 11 and the lower cover plate 12, avoiding leakage caused by the separation between the rubber head 20 and the air outlet due to the excessively fast water electrolysis speed when hydrogen or oxygen is discharged, and avoiding safety accidents caused by hydrogen leakage.

[0046] How this application works:

[0047] The lower cover plate 12 is placed on the middle plate 4 and supported by the support rod 7. The bipolar plate 13, the separator 14 and the positive and negative electrode stacks are manually installed on the lower cover plate 12 by the staff, and finally the upper cover plate 11 is installed. After the preliminary installation of the electrolytic cell is completed by installing a number of studs 17 in the column holes, the nuts 42 are installed at both ends of each stud 17, and then the docking structure is installed on the upper cover plate 11 and the lower cover plate 12 and connected with the nuts 42. The rotation of the rotating ring 5 is controlled to adjust the position of the adjustment part 6. Under the sliding cooperation between the adjustment part 6 and the roller 8, the entire electrolytic cell is moved downward. Damping can be set between the lower cover plate 12 and the lower base 1 to achieve the protection of the electrolytic cell, so that the slot 16 and the drive shaft 10 are docked. At the same time, the hydraulic cylinder 3 is controlled to shrink so that the upper base 2 moves downward, so that the drive shaft 10 on the upper base 2 and the slot 16 on the upper cover plate 11 are docked. At this time, the stepping motors 9 on the upper base 2 and the lower base 1 are controlled to be energized and rotated. Under the action of the transmission wheel and the belt Under the control, the driving shaft 10 is rotated, thereby driving the driving gear 15 to rotate. Under the meshing action between the driving gear 15 and the teeth 39, the inflation seat 35 and the nut 42 can be controlled to rotate. At this time, through the cooperation between the limit block 34 and the limit groove 18, the cylinder 37, the compensation sleeve 33 and the collar 36 are controlled not to rotate, thereby controlling the nut 42 and the compensation sleeve 33 to move downward. In this process, the stud 17 and the plug 40 conflict with each other, driving the plug 40 to move upward relative to the inflation seat 35. Thereby, the air in the inflation seat 35 is squeezed into the cylinder 37, driving the cylinder 37 to extend, so that the compensation sleeve 33 moves downward relative to the nut 42 and contacts and locks with the upper cover plate 11 or the lower cover plate 12, thereby realizing the compensation of the empty space between the nut 42 and the upper cover plate 11 / lower cover plate 12, and getting rid of the traditional manual locking and compensation method of setting a plurality of gaskets between the nut 42 and the upper cover plate 11 / lower cover plate 12 according to the use distance between the upper cover plate 11 and the lower cover plate 12 and the length of the stud 17. The protection main pipe 21 and the protection sub-pipe 22 are both sleeved on the surface of the stud 17. When controlling the distance between the upper cover plate 11 and the lower cover plate 12, the protection sub-pipe 22 can be resisted, driving the protection sub-pipe 22 to move relative to the protection main pipe 21. Under the meshing action between the rack 23 and the transmission gear 24, the protection sub-pipes 22 on both sides of the protection main pipe 21 are controlled to move synchronously, thereby driving the displacement of the protection sub-pipe 22 to be consistent, thereby realizing the protection treatment work for the studs 17 at different distances between the upper cover plate 11 and the lower cover plate 12.The locking structure is mounted and fixed on the rubber head 20 on the air outlet. When the hydrogen or oxygen produced by the electrolysis of water is discharged through the rubber head 20, the hydrogen and oxygen will generate air pressure in the rubber head 20. The air pressure value inside the rubber head 20 is different according to the strength of the electrolysis of water. When the air pressure value is large, part of the gas will enter the cavity 32 along the through hole 26, thereby controlling the movement of the slide plate 31, and then driving the piston rod 30 to move along the hollow tube 29. At this time, the air between the suction cup 27 and the upper cover plate 11 / lower cover plate 12 can be extracted to achieve a vacuum state, thereby improving the stable connection coefficient between the rubber head 20 on the air outlet and the upper cover plate 11 and the lower cover plate 12, avoiding leakage caused by the separation between the rubber head 20 and the air outlet due to the excessively fast electrolysis speed of water when the hydrogen or oxygen is discharged, and avoiding safety accidents caused by hydrogen leakage.
