Although the above document can also reduce the resistance between the electrode plates and the electrode mesh, thereby reducing the energy consumption of hydrogen production by water electrolysis, the elastic support also enables the components between the two electrode plates to be in close contact, forming an integrated module.

[0004] However, when the existing elastic support body is in use, the electrode plate and the electrode mesh are only contacted by the spring to reduce the resistance between the electrode plate and the electrode mesh. Since the contact area between the spring and the electrode plate and the electrode mesh is small, the contact between the electrode plate and the electrode mesh may be loose, and the electrode plate and the electrode mesh cannot be pressed against each other.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] When the existing elastic support body is in use, the contact area between the electrode plate and the electrode mesh is small, which may cause the electrode plate and the electrode mesh to have loose contact, thereby failing to press the electrode plate and the electrode mesh against each other.

[0023] In view of this, the utility model provides an electrolytic cell for hydrogen production by water electrolysis with an elastic support body. Through the cooperation among the sleeve, the first spring, the horizontal column, the first vertical plate, the second vertical plate and the recessed hole, the first vertical plate and the second vertical plate are pressed tightly against the two electrode plates and the two electrode nets, and the electrode nets and the electrode plates are tightly supported. This solves the problem that when the existing elastic support body is in use, the contact between the electrode plates and the electrode nets may be loose due to the small contact area between the spring and the electrode plates and the electrode nets, thereby making it impossible to press the electrode plates and the electrode nets against each other.

[0024] Through the help of people in this field, the electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection between the electrical components is completed in the order of working. The detailed connection means are well-known technologies in this field. The working principle and process are mainly introduced below, and the electrical control is no longer explained.

[0025] Example 1, by Figure 1-5It can be seen that the water electrolysis hydrogen production electrolyzer with an elastic support body in this case includes a cell body 1, and the inner wall of the cell body 1 is provided with a diaphragm 2, which separates the cathode and the anode to form cathode and anode chambers to prevent short circuit and avoid mixing of the gas products of the two poles. A first electrode mesh 3 and a first electrode plate 4 are respectively provided on one side of the diaphragm 2, the first electrode mesh 3 is the cathode, and the second electrode mesh 5 is the anode. At the same time, the first electrode mesh 3 and the second electrode mesh 5 are connected to an external power supply, hydrogen is generated on the first electrode mesh 3, and oxygen is generated on the second electrode mesh 5. The first electrode mesh 3 and the first electrode plate 4 are respectively installed on the inner wall of the cell body 1, and a second electrode mesh 5 and a second electrode plate 6 are respectively provided on the side of the diaphragm 2 away from the first electrode mesh 3. The surfaces of the first electrode plate 4 and the second electrode plate 6 are covered with spherical concave Convex structure (mastoid plate), these concave and convex structures can make the plates on both sides of the diaphragm 2 form reliable multi-point electrical contact in the form of "top to top". As much electrical contact as possible can reduce the contact resistance of the internal components of the chamber. At the same time, the first plate 4 and the second plate 6 are located at both ends of a complete chamber structure, forming a chamber for the flow of alkali solution in the cathode area and the anode area, realizing the diversion of the cathode alkali solution and the anode alkali solution, reducing the content of oxygen in hydrogen and hydrogen in oxygen to a certain extent, and ensuring the safety of the operation of the electrolytic cell. The second electrode mesh 5 and the second plate 6 are respectively installed in the interior of the tank body 1, and a support mechanism 7 is provided in the interior of the tank body 1. The support mechanism 7 is provided in eight groups. The support mechanism 7 includes: a sleeve 71, which is provided in the interior of the tank body 1, a horizontal column 73, The first spring 72 is sleeved on the inner wall of the sleeve 71, and the first vertical plate 74 drives the cross column 73 to move, and the cross column 73 moves in the sleeve 71. The two ends of the first spring 72 are respectively fixedly connected to the inner wall of the sleeve 71 and the end of the cross column 73 close to the sleeve 71. The first vertical plate 74 is fixedly connected to the other end of the cross column 73 away from the sleeve 71, and respectively adheres to the outer wall of the first electrode mesh 3 and the outer wall of the second electrode mesh 5. At the same time, the first spring 72 is squeezed, and then the staff fits the first vertical plate 74 and the second vertical plate 75 on the electrode mesh and the electrode plate respectively. At this time, the first spring 72 rebounds, and the first vertical plate 74 and the second vertical plate 75 are tightened to the electrode mesh and the electrode plate by elastic force, supporting the electrode mesh and the electrode plate, so that there is space for electrolyte flow between the electrode mesh and the electrode plate. The electrode plates and the electrode mesh can be connected, the resistance between the two can be reduced, and the energy consumption of hydrogen production by water electrolysis can be reduced, so that the first vertical plate 74 and the second vertical plate 75 can be pressed against the two electrode plates and the two electrode meshes to tightly support the electrode meshes and the electrode plates. The second vertical plate 75 is fixedly connected to the side of the sleeve 71 away from the horizontal column 73. The second vertical plate 75 drives the sleeve 71 to move and respectively fits the outer wall of the first electrode plate 4 and the outer wall of the second electrode plate 6. When support is needed between the electrode mesh and the electrode plates, the staff presses the first vertical plate 74 and the second vertical plate 75 on both sides. The fixing components 76 are respectively arranged inside the first vertical plate 74 and the second vertical plate 75, wherein the first vertical plate 74 is squeezed, and the first vertical plate 74 drives the horizontal column 73 to move in the sleeve 71.As a result, the first spring 72 is compressed, the first upright plate 74 is attached to the outer walls of the first electrode mesh 3 and the second electrode mesh 5, and the second upright plate 75 is attached to the outer walls of the first electrode plate 4 and the second electrode plate 6. The elastic force of the first spring 72 presses the first upright plate 74 and the second upright plate 75 against the two electrode plates and the two electrode meshes. The first upright plate 74 and the second upright plate 75 are fixed to the first electrode mesh 3, the second electrode mesh 5, the first electrode plate 4 and the second electrode plate 6 respectively by the fixing assembly 76, thereby improving the overall stability of the support mechanism 7.

[0026] During the specific implementation process, it is worth noting that the cathode and the anode are separated to form cathode and anode chambers to prevent short circuit and avoid mixing of gas products at the two poles. The first electrode mesh 3 is the cathode and the second electrode mesh 5 is the anode. At the same time, the first electrode mesh 3 and the second electrode mesh 5 are connected to an external power supply to generate hydrogen on the first electrode mesh 3 and oxygen on the second electrode mesh 5. The surfaces of the first electrode plate 4 and the second electrode plate 6 are covered with spherical concave-convex structures (mastoid plates). On the one hand, these concave-convex structures can enable the plates on both sides of the diaphragm 2 to form reliable multi-point electrical contact in the form of "top to top". As much electrical contact as possible can reduce the contact resistance of the internal components of the chamber. At the same time, the first electrode plate 4 and the second electrode plate 6 are located at both ends of a complete chamber structure, forming a chamber for the flow of alkali solution in the cathode region and the anode region, realizing the diversion of cathode alkali solution and anode alkali solution, reducing the content of oxygen in hydrogen and hydrogen in oxygen to a certain extent, and ensuring To ensure the safety of the electrolytic cell operation, the support mechanism 7 is provided with eight groups. When it is necessary to support the electrode mesh and the electrode plate, the staff presses the first vertical plate 74 and the second vertical plate 75 on both sides. The first vertical plate 74 drives the cross column 73 to move, and the cross column 73 moves in the sleeve 71. The second vertical plate 75 drives the sleeve 71 to move, and at the same time squeezes the first spring 72. Then the staff fits the first vertical plate 74 and the second vertical plate 75 to the electrode mesh and the electrode plate respectively. At this time, the first spring 72 rebounds and tightens the first vertical plate 74 and the second vertical plate 75 to the electrode mesh and the electrode plate through elastic force, supporting the electrode mesh and the electrode plate, so that there is space for electrolyte flow between the electrode mesh and the electrode plate, and the electrode plate and the electrode mesh can also be connected, thereby reducing the resistance between the two and reducing the energy consumption of hydrogen production by water electrolysis, so as to achieve the first vertical plate 74 and the second vertical plate 75 being pressed against the two electrode plates and the two electrode meshes, and tightly supporting the electrode mesh and the electrode plates;

[0027] Furthermore, the fixing assembly 76 includes: a connecting plate 763, which is respectively arranged inside the first vertical plate 74 and the second vertical plate 75, and a clamping block 761, which is respectively plugged into the inner wall of the first electrode mesh 3, the inner wall of the second electrode mesh 5, the inner wall of the first electrode plate 4, and the inner wall of the second electrode plate 6. When the electrode mesh and the electrode plate are supported, the first vertical plate 74 and the second vertical plate 75 drive the clamping blocks 761 on both sides to move, and align the clamping blocks 761 on both sides with the clamping grooves on the surface of the electrode mesh and the electrode plate. The second spring 762 has two ends respectively fixedly connected to the side of the connecting plate 763 close to the clamping block 761 and the side of the clamping block 761 close to the connecting plate 763. When the first vertical plate 74 and the second vertical plate 75 are supported, the clamping blocks 761 on both sides are driven to move, and the clamping blocks 761 on both sides are aligned with the clamping grooves on the surface of the electrode mesh and the electrode plate. When the first vertical plate 74 and the second vertical plate 75 are in contact with the surfaces of the electrode mesh and the electrode plate, the clamping blocks 761 on both sides are inserted into the clamping grooves on the surfaces of the electrode mesh and the electrode plate. The clamping blocks 761 are fixed by the elastic force of the second springs 762 on both sides, thereby fixing the support mechanism 7 and improving the stability of the support mechanism 7. This prevents bubbles from being generated in the electrolyte during hydrogen production, which causes water waves to form inside the electrolyte and thus causes the support mechanism 7 to move. The clamping blocks 761 on both sides are respectively inserted into the first electrode mesh 3, the second electrode mesh 5, the first electrode plate 4 and the second electrode plate 6 by the elastic force of the second springs 762, thereby improving the overall stability of the support mechanism 7.

[0028] During the specific implementation process, it is worth noting that when supporting the electrode mesh and the electrode plate, the first vertical plate 74 and the second vertical plate 75 drive the clamping blocks 761 on both sides to move, and align the clamping blocks 761 on both sides with the clamping grooves on the surface of the electrode mesh and the electrode plate. When the first vertical plate 74 and the second vertical plate 75 are in contact with the surface of the electrode mesh and the electrode plate, the clamping blocks 761 on both sides are inserted into the clamping grooves on the surface of the electrode mesh and the electrode plate. The clamping blocks 761 are fixed by the elastic force of the second springs 762 on both sides, thereby fixing the support mechanism 7, improving the stability of the support mechanism 7, and avoiding the generation of bubbles in the electrolyte during hydrogen production, resulting in the formation of water waves inside the electrolyte, thereby causing the support mechanism 7 to move;

[0029] Furthermore, a concave hole 751 is formed on the surface of the second vertical plate 75. When the second vertical plate 75 is attached to the two electrode plates, the concave hole 751 on the surface of the second vertical plate 75 mates with the concave-convex structure on the surfaces of the two electrode plates, so that the second vertical plate 75 fits tightly with the two electrode plates. The inner wall of the concave hole 751 fits with the outer wall of the first electrode plate 4 and the outer wall of the second electrode plate 6 respectively.

[0030] In the specific implementation process, it is worth noting that when the second vertical plate 75 is attached between the two electrode plates, the concave holes 751 on the surface of the second vertical plate 75 are attached to the concave and convex structures on the surfaces of the two electrode plates, so that the second vertical plate 75 is tightly attached to the two electrode plates.

[0031] Specifically, first, the staff presses the first vertical plate 74 and the second vertical plate 75 on both sides, the first vertical plate 74 drives the cross column 73 to move, the cross column 73 moves in the sleeve 71, and the second vertical plate 75 drives the sleeve 71 to move, and at the same time squeezes the first spring 72. Then the staff fits the first vertical plate 74 and the second vertical plate 75 on the electrode mesh and the electrode plate respectively. At this time, the concave hole 751 on the surface of the second vertical plate 75 fits with the concave and convex structure on the surface of the two electrode plates. At this time, the first spring 72 rebounds, and the first vertical plate 74 and the second vertical plate 75 are tightened to the electrode mesh and the electrode plate by elastic force, which is conducive to the electrode mesh and the electrode plate. Support is provided. At the same time, when supporting the electrode mesh and the electrode plate, the first vertical plate 74 and the second vertical plate 75 drive the blocks 761 on both sides to move, and align the blocks 761 on both sides with the grooves on the surface of the electrode mesh and the electrode plate. When the first vertical plate 74 and the second vertical plate 75 are in contact with the surface of the electrode mesh and the electrode plate, the blocks 761 on both sides are inserted into the grooves on the surface of the electrode mesh and the electrode plate. The elastic force of the second springs 762 on both sides fixes the blocks 761, so that there is space for electrolyte flow between the electrode mesh and the electrode plate, and the electrode plate and the electrode mesh can also be connected, thereby reducing the resistance between the two and reducing the energy consumption of hydrogen production by water electrolysis.

[0032] Example 2, by Figure 1-5 As can be seen, sealing rings 7611 are respectively installed on the inner walls of the first vertical plate 74 and the second vertical plate 75. The sealing rings 7611 increase the sealing between the clamping block 761 and the first vertical plate 74 and the second vertical plate 75 to prevent the electrolyte from entering the interior of the first vertical plate 74 and the second vertical plate 75. The inner wall of the sealing ring 7611 is in contact with the outer wall of the clamping block 761.

[0033] In the specific implementation process, it is worth noting that the sealing ring 7611 increases the sealing between the clamping block 761 and the first vertical plate 74 and the second vertical plate 75, thereby preventing the electrolyte from entering the interior of the first vertical plate 74 and the second vertical plate 75;

[0034] Furthermore, a connecting plate 763 is fixedly connected between the first vertical plate 74 and the second vertical plate 75 by bolts 7631. A worker can assemble the fixing assembly 76 by turning the bolts 7631. The inner walls of the first vertical plate 74 and the second vertical plate 75 are respectively installed with sealing gaskets 7632. The outer walls of the sealing gaskets 7632 are in contact with the inner wall of the connecting plate 763. The sealing gaskets 7632 increase the sealing between the connecting plate 763 and the first vertical plate 74 and the second vertical plate 75, further preventing the electrolyte from entering the interior of the first vertical plate 74 and the second vertical plate 75.

[0035] During the specific implementation process, it is worth noting that the staff can assemble the fixing assembly 76 by turning the bolt 7631, and at the same time, the sealing gasket 7632 increases the sealing between the connecting plate 763 and the first vertical plate 74 and the second vertical plate 75, further preventing the electrolyte from entering the interior of the first vertical plate 74 and the second vertical plate 75;

[0036] Furthermore, one side of the tank body 1 is connected to a drain pipe 11. The staff opens the valve on the drain pipe 11, and the electrolyte inside the tank body 1 is discharged from the tank body 1 through the drain pipe 11. After completion, the staff closes the valve on the drain pipe 11 and pours new electrolyte into the tank body 1 through the opening at the top of the tank body 1 to replace the electrolyte.

[0037] During the specific implementation process, it is worth noting that the staff opens the valve on the drain pipe 11, and the electrolyte inside the tank body 1 is discharged into the tank body 1 through the drain pipe 11. After completion, the staff closes the valve on the drain pipe 11 and then pours new electrolyte into the tank body 1 through the opening at the top of the tank body 1 to replace the electrolyte.

[0038] Specifically, the staff can assemble the fixing assembly 76 by turning the bolt 7631, the sealing ring 7611 increases the sealing between the block 761 and the first vertical plate 74 and the second vertical plate 75, and the sealing gasket 7632 increases the sealing between the connecting plate 763 and the first vertical plate 74 and the second vertical plate 75 to prevent the electrolyte from entering the interior of the first vertical plate 74 and the second vertical plate 75. The staff opens the valve on the drain pipe 11, and the electrolyte inside the tank body 1 is discharged into the tank body 1 through the drain pipe 11. After completion, the staff closes the valve on the drain pipe 11, and then pours new electrolyte into the tank body 1 through the opening at the top of the tank body 1 to replace the electrolyte.
