The first motor 17 drives the screw 16 to rotate, so that the movable platform 12 moves along the sliding connection with the limit frame 13.

The residual water on the battery pack drips from the leakage hole 15 on the movable platform 12 into the water guide groove 14, and then flows back to the bottom of the test box 1 along the water guide groove 14.
