The number of support members 22 corresponds to the number of conductors. Two of the support members 22 are arranged at intervals on the first connecting member 211, and the other support member 22 is disposed on the second connecting member 212. The positions of the support members 22 on the connecting member 21 are set according to the installation height of the conductor.

[0049] First, place the device into the tank body. Fix the device to the tank body by fixedly connecting the connecting plate 12 on the fixing seat 1 to the flange connection on the tank body. Then, pull up the connecting piece 21 and the positioning block 24 along the guiding piece 23 to make the positioning block 24 leave the positioning groove 11. Rotate the connecting piece 21 to make the supporting piece 22 in the supporting state. At this time, the supporting piece 22 is located outside the fixing seat 1. Put down the connecting piece 21 along the guiding piece 23 and place the positioning block 24 into the positioning groove 11. Then, place the conductors on the rollers 3 respectively and pull the conductors to the conductor connection points. After the conductors are installed, pull up the connecting piece 21 along the guiding piece 23 to make the positioning block 24 leave the positioning groove 11. Rotate the connecting piece 21 to make the supporting piece 22 in the storage state. At this time, the supporting piece 22 is located inside the fixing seat 1. Finally, disconnect the fixing seat 1 from the tank body and take the device out of the tank body.
