[0032] like Figures 1-6 As shown, it illustrates a modular water electrolysis hydrogen production device according to an embodiment of the present disclosure, which includes a connecting plate 1 and an electrode rod 2. The top end of the electrode rod 2 is connected to an external connecting line.

[0033] like Figure 4 and Figure 6 As shown, the protective sleeve 3 is fitted onto the outer surface of the electrode rod 2. A protective frame 5 is installed on the outer surface of the protective sleeve 3. There is a certain distance between the top inner wall of the protective sleeve 3 and the electrode rod 2. A buffer spring 6 is installed inside the protective frame 5. A protective post 7 is installed on the outer end of the buffer spring 6. The connecting frame 4 is installed on the upper surface of the connecting plate 1. A wire hole is opened on the inner side of the connecting frame 4. An auxiliary hole is opened on the upper surface of the protective sleeve 3. The protective post 7 is slidably connected to the protective frame 5. The outer side of the protective post 7 is slidably connected to the connecting frame 4 through a connecting groove. The moving plate 8 is installed on the upper surface of the protective post 7. A plug rod 9 is installed on the outer side of the moving plate 8. A connecting ring 10 is fitted onto the outer surface of the plug rod 9. A support plate 11 is installed on the outer surface of the connecting ring 10. The blocking door 12 is hinged to the upper surface of the connecting frame 4 through a hinge. The upper surface of the support plate 11 is installed on the lower surface of the blocking door 12. The fixing mechanism is set inside the connecting frame 4.

[0034] like Figure 4 As shown, the fixing mechanism includes a fixing rod 13, an extension rod 14, and a first blocking plate 15. The fixing rod 13 is threaded through the inside of the protective frame 5. One end of the fixing rod 13 threaded through the protective frame 5 is pressed against the protective post 7. Before the operator needs to open the blocking door 12, the fixing rod 13 needs to be loosened. The extension rod 14 is installed on the outer end of the fixing rod 13. The outer surface of the extension rod 14 penetrates the inside of the connecting frame 4. The first blocking plate 15 is installed on the outer end of the extension rod 14.

[0035] like Figure 5As shown, a mounting plate 17 is provided inside the connecting frame 4. A mounting pin 18 is threaded through the outer side of the mounting plate 17. One end of the mounting pin 18, threaded through the mounting plate 17, is threaded inside the connecting frame 4. An adjusting frame 19 is mounted on the upper surface of the mounting plate 17. An adjusting rod 20 is threaded through the inner side of the adjusting frame 19. A second blocking plate 21 is mounted on the outer end of the adjusting rod 20. A connecting rod 23 is mounted on the outer side of the adjusting frame 19. A clamping frame 24 is mounted on the outer end of the connecting rod 23. A clamping rod 24 is threaded through the inner side of the clamping frame 24. 5. An adjusting block 22 is slidably connected inside the adjusting frame 19. The inner end of the adjusting rod 20 is rotatably connected inside the adjusting block 22. A clamping spring 26 is installed inside the clamping frame 24. The outer surface of the clamping rod 25 passes through the inside of the clamping spring 26. A clamping frame 27 is installed at the inner end of the clamping rod 25 and the clamping spring 26. A clamping wheel 28 is rotatably connected inside the clamping frame 27. A clamping groove is opened on the inner side of the adjusting block 22 and the outer surface of the clamping wheel 28. The clamping wheel 28 can roll along the connecting line of the electrode rod 2.

[0036] In this embodiment, as Figure 4 As shown, a first movable handle 16 is installed on the upper surface of the blocking door 12, such as... Figure 1 and Figure 2 As shown, a processing box 35 is provided on the outer side of the connecting plate 1. A connecting pin 29 is threaded through the outer side of the processing box 35. One end of the connecting pin 29 is threaded through the processing box 35 and threaded inside the connecting plate 1. A second moving handle 30 is installed on the upper surface of the connecting plate 1. Two sets of exhaust pipes 31 are connected to the left and right sides of the upper surface of the connecting plate 1. A diaphragm 32 is installed on the lower surface of the connecting plate 1. A drain valve 34 is connected to the front of the processing box 35. The drain valve 34 is initially closed. A water inlet pipe 33 is passed through the upper surface of the connecting plate 1. The water inlet pipe 33 is inserted into the water during use to prevent the gas generated during the electrolysis of water from entering the water inlet pipe 33.

[0037] It should be noted that the electrode rod 2 on the left is the anode and the electrode rod 2 on the right is the cathode. Therefore, the exhaust pipe 31 on the left is the oxygen exhaust pipe and the exhaust pipe 31 on the right is the hydrogen exhaust pipe. The rear ends of the exhaust pipes 31 on the left and right sides are respectively connected to the storage tanks of the corresponding collected gases.

[0038] In this embodiment, the second moving handle 30 is manipulated to slide the connecting plate 1 into the processing box 35, the connecting pin 29 is manipulated to pass through the processing box 35 and insert into the connecting plate 1, and then the connecting pin 29 is tightened clockwise to fix the connecting plate 1 into the processing box 35, so that the electrode rod 2 and the water inlet pipe 33 enter the processing box 35.

[0039] The mounting plate 17 is pressed against the connecting frame 4. The mounting pin 18 is inserted into the connecting frame 4 through the mounting plate 17. The mounting pin 18 is then tightened clockwise to fix the mounting plate 17 in the connecting frame 4. The connecting wire is passed through the wire hole and through the adjusting frame 19 and the clamping frame 24, so that the clamping wheel 28 contacts the connecting wire. The clamping wheel 28 moves outward, driving the clamping frame 27 to move outward. The clamping frame 27 moves outward, driving the clamping rod 25 to move outward. The clamping rod 25 moves outward along the clamping frame 24. The clamping frame 27 moves outward, compressing the clamping spring 26. The connecting wire is clamped by the reaction force of the clamping spring 26. The second blocking plate 21 is rotated clockwise, causing the adjusting rod 20 to move inward along the adjusting frame 19. The adjusting rod 20 moves inward, driving the adjusting block 22 to move inward. The adjusting block 22 moves inward and contacts the connecting wire, fixing it in place.

[0040] Then, it passes through the inside of the protective sleeve 3 and connects with the electrode rod 2 (at this time, the blocking door 12 is in the open state). The protective column 7 is manipulated to move inward along the protective frame 5. The protective column 7 moves inward to compress the buffer spring 6. The protective sleeve 3 is manipulated to fit on the outer surface of the electrode rod 2, so that the protective sleeve 3 contacts the connecting plate 1. The first blocking plate 15 is manipulated to pass through the connecting frame 4, so that the fixing rod 13 is inserted into the inside of the protective frame 5. Then, the first blocking plate 15 is rotated clockwise to tighten the fixing rod 13 through the extension rod 14, so that the fixing rod 13 abuts against the protective column 7.

[0041] Manipulate the first moving handle 16 to flip the blocking door 12 downwards and close it. The downward flip of the blocking door 12 causes the support plate 11 to flip downwards, and the downward flip of the support plate 11 causes the connecting ring 10 to flip downwards. Loosen the first blocking plate 15 counterclockwise, so that the fixing rod 13 rotates out of the protective frame 5. The buffer spring 6 rebounds and causes the protective column 7 to move outwards. The protective column 7 moves outwards and slides into the connecting frame 4. The outward movement of the protective column 7 causes the moving plate 8 to move outwards, and the outward movement of the moving plate 8 causes the plug-in rod 9 to move outwards. The plug-in rod 9 moves outwards and inserts into the connecting ring 10 to fix the blocking door 12.

[0042] Water is poured into the treatment tank 35 through the inlet pipe 33. By turning on the external single-control switch, the external DC power supply powers the two sets of electrode rods 2 through the connecting wire. The current is conducted between the electrode rods 2, the connecting wire and the water, so that the electrode rod 2 on the left electrolyzes water to produce oxygen and the electrode rod 2 on the right electrolyzes water to produce hydrogen. The oxygen is discharged through the exhaust pipe 31 on the left and the hydrogen is discharged through the exhaust pipe 31 on the right. The water on the left and right sides of the treatment tank 35 is synchronously transferred through the diaphragm 32, which can block the two gases.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
