then the filtering component (4) and the spraying component (3) are continuously lowered to a second section position to be washed in the well (5), at the moment, the second opening (311) in the spraying component (3) is butted and communicated with the first opening (21) in the corresponding second section position in the well (5) on the water pumping pipeline (2), so that the water in the water pumping pipeline (2) can continuously enter the spraying component (3) for continuous use;
and then, cleaning work of the second section position to be cleaned in the well (5) is completely the same as that of the first section position, and after the cleaning work of the second section position to be cleaned in the well (5) is finished, cleaning work of the third section position in the well (5) is carried out according to the same steps until the inner wall of the well (5) is completely cleaned.
