[0028] By arranging a first counterweight block 23 inside the cavity 21 and installing a second counterweight block 25 at the bottom of the side plate 24, the moving plate 2 can move downward in groundwater to clean the impurities avoided by the heat exchange tube 12;

[0029] During use, the top plate 31 needs to be installed on the ground, which facilitates subsequent maintenance of the damaged drive motor 33 by the user.

[0030] The heat exchange tube 12 is arranged on the inner side surface of the through hole 22, and the inner wall of the through hole 22 is closely attached to the outer side surface of the heat exchange tube 12.
