[0035] like Figure 1 , Figure 2 and Figure 5As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the power assembly includes a connecting shell 403 rotatably connected to the top of the transmission shaft 401, a bevel gear set 405 fixed to the top of the transmission shaft 401, a wind impeller 404 rotatably connected to one side of the connecting shell 403 and connected to the bevel gear set 405, and a wind deflector 402 fixed to one side of the connecting shell 403, the transmission shaft 401 extends to the interior of the connecting shell 403 and is connected to the bevel gear set 405, the transmission shaft 401 forms a rotating structure with the PE pipe 3 through a ball bearing 408, and two groups of support frames 406 are provided, and the two groups of support frames 406 are symmetrically divided on the horizontal center line of the suction impeller 407. The wind force drives the wind impeller 404 to rotate, so that the wind impeller 404 drives the transmission shaft 401 to rotate through the bevel gear set 405, and then the transmission shaft 401 drives the suction impeller 407 to rotate inside the PE pipe 3, and the gas at the bottom of the PE pipe 3 is discharged upward, so that a negative pressure is formed at the bottom of the PE pipe 3, so as to discharge the gas in the sewage and reduce the bubbles at the bottom of the geomembrane 1.
