The tooling is used to facilitate the support and fixation of the electrolytic cell module 2, thereby ensuring the normal operation of the device.

[0043] Combine Figure 4 As shown, there are two sets of guide rails 111 arranged in parallel and symmetrically, and the guide rails 111 are located at the bottom of the electrolytic cell module tooling. The anode end plate 121, the cathode end plate 122 and the electrolytic cell module 2 are all arranged above the guide rails 111. Figure 1 and Figure 2 As shown, both ends of the guide rail 111 are provided with a limiter 14, the inner side of the limiter 14 is provided with an anode end plate 121 and a cathode end plate 122, and a plurality of electrolytic cell modules 2 are provided between the anode end plate 121 and the cathode end plate 122. Figure 1 and Figure 2 As shown, the limit members 14 provided at both ends of the guide rail 111 are used to define the initial positions of the anode end plate 121 and the cathode end plate 122. The bottoms of the anode end plate 121 and the cathode end plate 122 are provided with grooves that match the guide rail 111. The bottom of the anode end plate 121 is provided with guide wheels 112 that adapt to the guide rail 111. The anode end plate 121 can move along the guide rail 111, thereby pushing the electrolyzer module 2 for compaction.

[0044] Combine Figure 1 、 Figure 5 and Figure 7 As shown, the anode end plate 121 and the cathode end plate 122 are arranged on the left and right sides of the guide rail 111, and are arranged in a vertical direction. The anode end plate 121 and the cathode end plate 122 are provided with an oxygen liquid outlet 151, a hydrogen liquid outlet 152, and an alkali liquid inlet 153 for accommodating the oxygen liquid outlet pipe, the hydrogen liquid outlet pipe, and the alkali liquid inlet pipe. In addition, the anode end plate 121 and the cathode end plate 122 are provided with a lifting ring 17 for convenient and quick lifting operations.

[0045] Combine Figure 1 and Figure 7 As shown, multiple tie rods 131 are horizontally arranged along the circumferential edges of the anode end plate 121 and the cathode end plate 122. One end of the tie rod 131 passes through the anode end plate 121, and the other end of the tie rod 131 is connected to the cathode end plate 122. The end of the tie rod 131 extending from the anode end plate 121 is provided with a tie rod nut 132 and a disc spring 133, wherein the disc spring 133 is arranged between the tie rod nut 132 and the anode end plate 121, and the tie rod nut 132 passes through one end of the tie rod 131 and is close to the disc spring 133.

[0046] The tie rods 131 are high-strength, round steel rods with a diameter of 20-50 mm. The ends of the tie rods 131 are bolted to the anode end plate 121 and the cathode end plate 122. The tie rods 131 inherently possess a certain degree of rigidity. When secured with bolts, they restrict movement of the electrolyzer modules 2 and facilitate precise positioning of the electrolyzer modules 2. To maximize their positioning function, in the embodiment of the present invention, the tie rods 131 are arranged in parallel to maintain the stability of the electrolyzer assembly during assembly, transportation, and unloading. The tie rods 131 are symmetrically positioned above, below, and on the front and rear sides of the electrolyzer modules 2.

[0047] Combine Figure 1 and Figure 7 As shown, the top tie rods 131 are connected by tie rod connectors 16. Tie rod connectors 16 are used to securely connect the tie rods 131 above the electrolyzer module 2, enhancing the overall stability of the device. Tie rod connectors 16 are also provided with lifting rings 17 to further facilitate the lifting and securing of the electrolyzer module 2, improving operational efficiency. Preferably, there are two or more sets of lifting rings 17 to facilitate lifting operations.

[0048] Combine Figures 1 to 3 As shown, a plurality of through holes are provided on the anode end plate 121 and the cathode end plate 122 , and the diameter of the through holes matches the diameter of the tie rod 131 , so as to facilitate the passage and fixation of the tie rod 131 .

[0049] The installation space for the electrolytic cell module 2 is enclosed by the anode end plate 121, the cathode end plate 122, and the pull rod 131. The disc spring 133 absorbs or supplements the deformation of the electrolytic cell module 2 caused by temperature changes, ensuring that the entire electrolytic cell module tooling is always in a state of pressing the electrolytic cell module 2. Among them, the number of disc springs 133 is determined according to the specifications of the electrolytic cell module 2, and preferably two or more groups. When the pull rod nut 132 is tightened, the disc spring 133 is compressed by force, and the anode end plate 121 is forced to move along the guide rail 111, gently pushing the electrolytic cell modules 2 to press against each other, thereby tightening the electrolytic cell module 2.

[0050] Combine Figures 1 to 7As shown, the present invention also proposes an electrolytic cell device, which mainly includes an electrolytic cell module 2 and an electrolytic cell module tooling, and the electrolytic cell module tooling adopts the electrolytic cell module tooling described above. The electrolytic cell module 2 is provided with multiple and all are arranged between the anode end plate 121 and the cathode end plate 122. The electrolytic cell anode end plate and the electrolytic cell cathode end plate are arranged on both sides of the electrolytic cell module 2, and the bottom of the electrolytic cell cathode end plate and the electrolytic cell anode end plate are also provided with guide wheels 112. The electrolytic cell module 2 is connected to the guide rail 111 through the guide wheels 112 arranged at the bottom, which can ensure that the electrolytic cell module 2 moves from left to right on the guide rail 111 and is then pressed. The top of the electrolytic cell cathode end plate and the electrolytic cell anode end plate is also provided with a lifting ring 17 to facilitate and quickly lift the electrolytic cell module 2 and facilitate operation and assembly.

[0051] Insulating plates and pressure plates are installed between the guide wheels 112 and the cathode and anode end plates of the electrolytic cell. The insulating plates block the electrical current and act as an insulator. The pressure plates increase the contact area between the guide wheels 112 and the end plates, thereby increasing the stability of the entire device and improving its load-bearing capacity. To ensure a tight fit, the insulating plates and pressure plates are fastened together with bolts. This design takes into account both the electrical safety and mechanical stability of the device, making the entire electrolytic cell device more reliable and durable.

[0052] The assembly process and working principle of the electrolyzer module tooling in this embodiment are as follows:

In the installation area surrounded by the rod 131, the guide wheels 112 at the bottom of the anode end plate 121 and the cathode end plate 122 are set on the guide rail 111, and then the upper pull rod 131 is passed through the grooves of the anode end plate 121 and the cathode end plate 122, and the disc spring 133 is installed in turn, and the pull rod nut 132 set at the end of the pull rod 131 is preliminarily tightened; finally, the pull rod nut 132 is tightened a second time, and the disc spring 133 is compressed under force, thereby gently pushing the electrolytic cell module 2 to slide on the guide rail 111, so that the electrolytic cell modules 2 are tightly fitted together, and finally the docking seal between the interfaces of the electrolytic cell modules 2 and the conductivity between the electrolytic cell modules 2 are completed.

[0054] The present invention proposes a tooling for an electrolytic cell module, which sets the electrolytic cell module 2 between the anode end plate 121 and the cathode end plate 122, and restricts and positions it by a plurality of parallel arranged tie rods 131. At the same time, a disc spring 133 and a tie rod nut 132 are added to one end of the tie rod 131 to flexibly adjust the deformation caused by the temperature change of the electrolytic cell module 2, so that the entire electrolytic cell module 2 is always in a compressed state; by adding a plurality of lifting rings 17, it is convenient to lift and fix the electrolytic cell module 2, thereby improving the assembly and operation efficiency; by adding guide wheels 112 at the bottom of the electrolytic cell module 2 and the bottom of the anode end plate 121, it is convenient to move and compress the electrolytic cell module 2, and facilitate operation and installation. The electrolytic cell device proposed in the present invention adopts a modular design, which can improve work efficiency, reduce labor intensity, reduce the difficulty of installation and operation, realize standardized production, and facilitate large-scale application. The electrolytic cell module tooling and electrolytic cell device of the utility model have a simple overall structure and are easy to use. They can quickly and accurately combine and connect the electrolytic cell modules 2 together, which is of great significance to the development of large-scale electrolytic cells.
