Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and in particular to a positioning device for assembling large PEM electrolytic cells. Background Technology

[0002] With the development of renewable energy, water electrolysis for hydrogen production has gained widespread attention due to its clean and pollution-free nature. In large-scale PEM electrolyzers, the number of cores often exceeds 100, requiring precise alignment during assembly to ensure electrolysis efficiency. However, traditional methods relying solely on positioning rods are inadequate for such a large number of cores. Due to the sheer number of cores, immense pressure must be applied to the electrolyzer during assembly to ensure proper compression. This uneven pressure during core stacking can cause the positioning rods to deform, leading to core tilting or misalignment, severely impacting the PEM electrolyzer's efficiency and lifespan. Therefore, developing a technology that effectively prevents positioning rod deformation and ensures proper core assembly is crucial. Utility Model Content

[0029] Reference Figures 1 to 5 The positioning device for assembling large PEM electrolytic cells according to this utility model is illustrated in the following embodiment:

[0030] The positioning device for assembling large PEM electrolyzers includes an electrolyzer base 100 and a positioning assembly 200. The positioning assembly 200 effectively prevents deformation of the positioning rod 210, ensuring proper assembly of the cell core 300. This device aims to solve the problem of slippage and misalignment caused by the large number of cell cores 300, as well as the problem of deformation of the traditional positioning rod 210 due to uneven stress under high pressure.

[0031] Specifically, the electrolytic cell base 100 is provided with various mounting holes for mounting other components and positioning components 200, including pre-set positioning holes for inserting positioning rods 210.

[0032] The positioning assembly 200 includes a positioning block 240, a positioning rod 210, a support base 220, and a long clamping block 230. The long clamping block 230 is tightly engaged with the positioning rod 210 to effectively prevent the positioning rod 210 from deforming under force; the support base 220 is used to support the long clamping block 230 to ensure its stability; the positioning block 240 is tightly installed next to the bottom of the support base 220 to achieve rapid and accurate positioning and ensure the verticality and accuracy of the entire electrolytic cell.

[0033] The positioning rod 210 is vertically installed in the electrolytic cell base 100 via a positioning insert. The positioning block 240 is located on the electrolytic cell base 100 and extends along the diagonal of the electrolytic cell base 100. The positioning block 240 has multiple screw holes 241. During installation, screws pass through the screw holes 241 to fix the positioning block 240 to the electrolytic cell base 100. There are various positioning methods for the positioning block 240. In this embodiment, the side of the positioning block 240 is a guide surface, and the support base 220 is attached to the guide surface for positioning. The positioning block 240 is made of aluminum alloy.

[0034] In some other embodiments, the positioning block 240 is provided with a limiting groove, and the support base 220 is provided with a limiting block that matches the limiting groove. The size and shape of the positioning block 240 are designed according to the specific structure of the electrolytic cell to ensure that it can quickly calibrate the position of the support base 220.

[0035] The support base 220 is located on the base 100 of the electrolytic cell and is situated outside the positioning rod 210. The support base 220 includes a base plate 221 and a vertical support block 222, which is vertically mounted on the base plate 221. The material of the support base 220 should have sufficient strength and rigidity. It adopts an L-shaped design, with the vertical portion contacting the side of the long clamping block 230 to provide horizontal support.

[0036] Furthermore, the base plate 221 and the vertical support block 222 are integrally formed, which can improve the structural strength of the support base 220 on the one hand, and ensure the verticality of the vertical support block 222 on the other hand.

[0037] To further enhance the support strength of the support base 220, a reinforcing rib 223 is provided between the base plate 221 and the vertical support block 222. As an additional support structure connecting the base plate 221 and the vertical support block 222, the reinforcing rib 223 effectively disperses and resists external loads, thereby significantly improving the structural stability of the entire support base 220. This design allows the support base 220 to maintain its shape and functional integrity when facing various pressures or impacts. Furthermore, the reinforcing rib 223 also improves the bending strength and load-bearing capacity of the support base 220. In this embodiment, referring to 4, the reinforcing rib 223 is a triangular support plate. In other embodiments, the design of the reinforcing rib 223 can be adjusted according to actual needs, including its quantity, shape, size, and position.

[0038] The long clamping block 230 has a fixed side and a supporting side on its two sides. The fixed side is fixed close to the side of the vertical supporting block 222, and the supporting side has a groove 231, which is inserted into the positioning rod 210. The groove 231 and the positioning rod 210 are matched, and the cross-sectional shape of the groove 231 matches the positioning rod 210 to prevent the positioning rod 210 from deforming under pressure. The long clamping block 230 is made of aluminum alloy.

[0039] To better ensure the supporting effect of the long clamping block 230 and the support base 220, the vertical support block 222 is provided with a slot. The fixed side is inserted into the slot, and the vertical support block 222 is fixed to the fixed side with screws. When installing the long clamping block 230, the long clamping block 230 is simultaneously inserted into the slot and the positioning rod 210, and then the long clamping block 230 is fixed to the vertical support block 222 with screws. This ensures the verticality of both the positioning rod 210 and the long clamping block 230, effectively supporting the positioning rod 210.

[0040] In other embodiments, the vertical support block 222 is provided with a guide protrusion, and the fixed side is provided with a guide groove that matches the guide protrusion. The vertical support block 222 is fixed to the fixed side with screws.

[0041] Finally, in this embodiment, there are two positioning components 200: two positioning rods 210, two support seats 220, and two long clamping blocks 230 are all located on the diagonal of the electrolytic cell base 100. In actual operation, different long clamping blocks 230 can be replaced, and the positions of the support seats 220 and positioning blocks 240 can be adjusted according to the specifications of the electrolytic cell.

[0042] During the actual assembly process, first clean the inside of the electrolytic cell to ensure that no debris will affect the installation of the cell core 300. Check that all cell cores 300 are intact and arranged in the predetermined order. Insert the positioning rod 210 into the pre-designed hole, ensuring its verticality. At this point, a small number of cell cores 300 can be initially placed to check whether the position of the positioning rod 210 is correct. Figure 1 As shown, the positioning block 240 is fixed to the electrolytic cell base 100 with fasteners to quickly and accurately determine the position of the support base 220. Then, the support base 220 is installed, and its base plate 221 is stably fixed to the bottom of the electrolytic cell with fasteners. Next, the long clamping block 230 is installed, with the vertical part of the support base 220 contacting the side of the long clamping block 230. The long clamping block 230 has threaded holes on its surface, through which the support base 220 is connected to the positioning block 240. The long clamping block 230 has a groove 231 inside, designed according to the specifications of the positioning rod 210 to ensure a tight fit and prevent deformation. The stable connection of the entire external positioning assembly 200 ensures that all cell cores 300 maintain good verticality and parallelism. With the support of the external positioning assembly 200, the remaining cell cores 300 are installed until all are completed. During this process, the verticality and flatness of the cell cores 300 should be checked regularly to ensure assembly quality. After all the slot cores 300 are installed, a comprehensive inspection is carried out, including but not limited to the gaps between the slot cores 300, the status of the positioning rods 210 and the external positioning components 200, to ensure that everything meets the technical requirements.

[0043] This utility model has the following advantages: the tight combination of the long clamping block 230 and the positioning rod 210 effectively prevents the positioning rod 210 from being deformed by pressure, ensuring the verticality and accuracy of the cell core 300; the design of the support base 220 provides additional support, enhances the stability of the entire positioning system, and improves the working reliability and service life of the electrolytic cell; the positioning accuracy of the cell core 300 is improved by reducing the number of parts, making it suitable for large electrolytic cell systems of different models; and the wear caused by inaccurate positioning is reduced, which helps to extend the service life of the electrolytic cell and related components.

[0044] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
