The wiper blade 2 is composed of a first tab 21 and a second tab 22, and the first tab 21 and the second tab 22 may be made of other materials such as elastic metal sheets or plastics having a certain elastic capability. One end of the first folding piece 21 is fixed on the end face of the main body ring 1, the other end of the first folding piece 21 is fixedly connected with the second folding piece 22 at a certain bending angle, and a plurality of clearance grooves are formed in the second folding piece 22. The doctor blade 2 has certain deformability due to the bending and the existence of the clearance groove, so that the pipe wall of the water pipe with different inner diameters can be cleaned within a certain range;

In this embodiment, the cleaning device comprises an adaptive moving mechanism 3 which is convenient for the cleaning device to move in water pipes with different pipe diameters, and the adaptive moving mechanism 3 is provided with four annular arrays which are arranged in a central shaft of the main body ring 1. Each adaptive moving mechanism 3 comprises a spherical shaft sleeve 31 and a ball 32 which are rotatably sleeved with each other, the outer wall of the spherical shaft sleeve 31 is fixedly connected with one end of a screw shaft 33, and the other end of the screw shaft 33 is fixedly connected with a gear 34. The body ring 1 is provided with an internal thread groove matching the screw shaft 33, the internal thread groove being located on a radial line of the body ring 1, which causes the screw shaft 33 to move radially by screwing with the screw thread of the screw shaft 33. The inner wall of the main body ring 1 is fixedly connected with four toothed ring sleeves 36 in a central shaft annular array, and the toothed ring 35 simultaneously penetrates through the toothed ring sleeves 36, so that the toothed ring 35 can coaxially rotate with the main body ring 1. The ring gear 35 is meshed with the four gears 34 at the same time, and thus, all the gears 34 can be driven to rotate at the same time. Specifically, when the toothed ring 35 is rotated, the toothed ring 35 drives all the gears 34 to rotate at the same time, so as to drive all the screw shafts 33 to rotate, and the screw shafts 33 drive the spherical shaft sleeve 31 and the balls 32 to move radially along the main body ring 1 to adjust positions through screw thread screwing between the screw shafts 33 and the internal thread grooves until the balls 32 are tangent to the inner wall of the water pipe.
