Figure 7As shown, after the fasteners 9 are fixed by passing through the end plate of the electrolytic cell 100 and the corresponding mounting holes 111 of the base frame 1, the adjustable support 2 and the insulating support 3 are restricted between the base frame 1 and the electrolytic cell 100, thereby fixing the electrolytic cell 100 and the support frame as a whole. When the electrolytic cell 100 is not in operation, the support frame is used as a support for the static storage of the electrolytic cell 100. When the electrolytic cell 100 needs to be moved, the electrolytic cell 100 and the support frame can be moved together as a whole. After the transfer, there is no need to rearrange the support structure, which greatly improves the convenience of moving the electrolytic cell 100 and installing it after the transfer, and reduces time and labor costs.

[0029] When the electrolytic cell 100 needs to be put into use, the fastener 9 connected to the mounting hole 111 at the end of the sliding member 5 on the base frame 1 is removed, so that one end of the electrolytic cell 100 is fixed relative to the base frame 1, and the other end forms a sliding fit with the base frame 1.
