Technical Field

[0001] This utility model relates to the field of bipolar plate technology for electrolyzers, specifically a rapid assembly and positioning assembly for bipolar plates in an alkaline water electrolysis hydrogen production electrolyzer. Background Technology

[0002] Alkaline water electrolysis for hydrogen production technology is highly mature and is the mainstream technology for hydrogen production in China. Large-scale electrolyzers, such as megawatt-level ones, are becoming the development trend. However, bipolar plates, as the core components of electrolyzers, are large in size and numerous in large equipment. Their assembly is a critical link in the stacking of electrolyzers, and the assembly efficiency directly affects the hydrogen energy production capacity. There is an urgent need for suitable positioning components to improve the assembly speed. When assembling and positioning bipolar plates, a rapid assembly and positioning component for bipolar plates of alkaline water electrolysis for hydrogen production electrolyzers is required. Most of the quick assembly and positioning assemblies for bipolar plates currently in use have difficulty adjusting the first threaded rod to the appropriate position according to bipolar plates of different sizes. During use, if it is difficult to move and adjust the first threaded rod to the appropriate position, the electrolytic cell may only be able to quickly assemble and position bipolar plates of the same model and size, which narrows the applicability and reduces the flexibility of the quick assembly and positioning assembly. Utility Model Content

[0003] The purpose of this invention is to provide a rapid assembly and positioning component for bipolar plates in an alkaline water electrolysis hydrogen production electrolyzer, in order to solve the problems mentioned in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rapid assembly and positioning assembly for bipolar plates in an alkaline water electrolysis hydrogen production electrolyzer, comprising an electrolyzer body and a bipolar plate body. The inner wall of the electrolyzer body is provided with a moving adjustment mechanism, which includes a support plate. The bottom of the support plate is provided with a guide rail, the outer wall of the guide rail is provided with a slider, and one side of the slider is provided with an mounting plate.

[0005] As a preferred technical solution, threaded holes are provided inside both the mounting plate and the electrolytic cell body, and bolts are provided on the inner wall of the threaded holes.

[0006] As a preferred technical solution, the number of mounting plates is two sets, with two plates in each set, and the shape of the mounting plates is rectangular.

[0007] As a preferred technical solution, a positioning and mounting mechanism is provided on one side of the mounting plate, the positioning and mounting mechanism including a first threaded rod, and the first threaded rod is provided on one side of the mounting plate.

[0008] As a preferred technical solution, a first nut is provided on the outer wall of the first threaded rod, and a double-stage plate body is provided on the outer wall of the first threaded rod.

[0009] As a preferred technical solution, a second nut is provided on the outer wall of the first threaded rod, and a second threaded rod is provided on the inner wall of the electrolytic cell body.

[0010] As a preferred technical solution, the outer wall of the second threaded rod is provided with a first nut, and the outer wall of the second threaded rod is provided with a double-stage plate body.

[0011] As a preferred technical solution, a second nut is provided on the outer wall of the second threaded rod, and there are two bipolar plate bodies, which are symmetrically arranged with the vertical center line of the electrolytic cell body as the axis of symmetry.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of the movable adjustment mechanism, can achieve the function of moving and adjusting the first threaded rod to a suitable position according to the model and size of the bipolar plate. During use, the mounting plate is moved and adjusted to a suitable position by sliding the slider on the outer wall of the guide rail. Then, the first threaded rod is adjusted to a suitable position and fixed by the cooperation of the threaded hole and the bolt. This can avoid the situation where the electrolytic cell can only be quickly assembled and positioned with bipolar plates of the same model and size due to the difficulty in moving and adjusting the first threaded rod to a suitable position, thus ensuring the applicability and flexibility of the quick assembly and positioning component.

[0013] 2. This utility model, through the setting of the positioning and installation mechanism, can achieve the function of positioning and fixing the bipolar plate inside the electrolytic cell. During use, through the cooperation of the first threaded rod, the second threaded rod, the first nut and the second nut, the bipolar plate is directly positioned in the appropriate position and fixed. This avoids the situation where it takes a long time to position and install the bipolar plate in the electrolytic cell, which would delay the progress of subsequent work and make the installation process more complicated, thus ensuring the convenience of this quick assembly positioning component.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1 and Figure 2 As shown, the present invention provides the following technical solution, including an electrolytic cell body 1 and a double-stage plate body 4. The inner wall of the electrolytic cell body 1 is provided with a moving adjustment mechanism 2, and one side of the mounting plate 204 is provided with a positioning mounting mechanism 3. The outer wall of the first threaded rod 301 is provided with a double-stage plate body 4, and the outer wall of the second threaded rod 304 is provided with a double-stage plate body 4.

[0018] Specifically: When the quick assembly positioning component is needed, the position of the first threaded rod 301 needs to be adjusted according to the model of the bipolar plate body 4. The position of the first threaded rod 301 is adjusted according to the model of the bipolar plate body 4 by the set moving adjustment mechanism 2. After the first threaded rod 301 is adjusted to the appropriate position, the two bipolar plate bodies 4 can be positioned and installed by the set positioning and installation mechanism 3, thereby completing the work.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the electrolytic cell body 1 is provided with a moving adjustment mechanism 2. The moving adjustment mechanism 2 includes a support plate 201, a guide rail 202 is provided at the bottom of the support plate 201, a slider 203 is provided on the outer wall of the guide rail 202, and a mounting plate 204 is provided on one side of the slider 203. Threaded holes 205 are opened in the interior of the mounting plate 204 and the interior of the electrolytic cell body 1. Bolts 206 are provided on the inner wall of the threaded holes 205. There are two sets of mounting plates 204, two in each set, and the shape of the mounting plates 204 is rectangular.

[0020] Specifically: When the quick assembly positioning component is needed, the position of the first threaded rod 301 needs to be adjusted according to the model of the bipolar plate body 4. At this time, the bolt 206 is rotated out of the threaded hole 205 to disengage the mounting plate 204 from the electrolytic cell body 1. Then, the mounting plate 204 is grasped and moved up or down. During the movement of the mounting plate 204, the sliding of the slider 203 on the outer wall of the guide rail 202 makes the movement of the mounting plate 204 more stable and smooth. The mounting plate 204 is moved and adjusted to a suitable position so that the threaded hole 205 in the mounting plate 204 is aligned with the corresponding threaded hole 205 in the electrolytic cell body 1. Then, the bolt 206 is rotated and inserted into the threaded hole 205 to fix the position of the mounting plate 204, thereby adjusting and fixing the first threaded rod 301 to a suitable position, thus completing the movement work.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a positioning and mounting mechanism 3 is provided on one side of the mounting plate 204. The positioning and mounting mechanism 3 includes a first threaded rod 301. The first threaded rod 301 is provided on one side of the mounting plate 204. A first nut 302 is provided on the outer wall of the first threaded rod 301. A double-stage plate body 4 is provided on the outer wall of the first threaded rod 301. A second nut 303 is provided on the outer wall of the electrolytic cell body 1. A second threaded rod 304 is provided on the inner wall of the electrolytic cell body 1. A first nut 302 is provided on the outer wall of the second threaded rod 304. A double-stage plate body 4 is provided on the outer wall of the second threaded rod 304. A second nut 303 is provided on the outer wall of the second threaded rod 304. There are two double-stage plate bodies 4, and the two double-stage plate bodies 4 are symmetrically arranged with the vertical center line of the electrolytic cell body 1 as the axis of symmetry.

[0022] Specifically: After adjusting the first threaded rod 301 to a suitable position, the two bipolar plate bodies 4 can be positioned and installed. The first nut 302 is then rotated and inserted into the outer walls of the first threaded rod 301 and the second threaded rod 304. The through holes inside the bipolar plate body 4 are then aligned with the first threaded rod 301 and the second threaded rod 304. The through holes are then inserted into the outer walls of the first threaded rod 301 and the second threaded rod 304, positioning the bipolar plate body 4 in a suitable position. The second nut 303 is then rotated and inserted into the outer walls of the first threaded rod 301 and the second threaded rod 304, securing the bipolar plate body 4 in place. The other bipolar plate body 4 is positioned and installed in the same manner, thus completing the positioning and installation work.

[0023] The working principle of this utility model is as follows: When the quick assembly positioning component is needed, the position of the first threaded rod 301 needs to be adjusted according to the model of the bipolar plate body 4. At this time, the bolt 206 is rotated out of the threaded hole 205 to disengage the mounting plate 204 from the electrolytic cell body 1. Then, the mounting plate 204 is grasped and moved up or down. During the movement of the mounting plate 204, the sliding of the slider 203 on the outer wall of the guide rail 202 makes the movement of the mounting plate 204 more stable and smooth. The mounting plate 204 is moved and adjusted to a suitable position so that the threaded hole 205 in the mounting plate 204 is aligned with the corresponding threaded hole 205 in the electrolytic cell body 1. Then, the bolt 206 is rotated and inserted into the threaded hole 205 to fix the position of the mounting plate 204, thereby adjusting and fixing the first threaded rod 301 to a suitable position. This completes the movement process. After adjusting the first threaded rod 301 to a suitable position, the two bipolar plate bodies 4 can then be positioned and installed. The first nut 302 is rotated and inserted into the outer walls of the first threaded rod 301 and the second threaded rod 304. The through holes inside the bipolar plate body 4 are then aligned with the outer walls of the first and second threaded rods 301 and 304. The bipolar plate body 4 is then positioned in the appropriate position. The second nut 303 is then rotated and inserted into the outer walls of the first and second threaded rods 301 and 304, securing the bipolar plate body 4 in place. The other bipolar plate body 4 is positioned and installed in the same manner, thus completing the positioning and installation process.
