Pipeline cleaning device with rotating structure for building water supply and drainage

The utility model belongs to the technical field of pipeline cleaning devices, and particularly relates to a pipeline cleaning device with a rotating structure for building water supply and drainage. A dredging rod is slidably connected to one end in the supporting frame. A plurality of groups of first springs are fixedly connected to the outer wall of one end of the dredging rod in a surrounding manner, and the other ends of the first springs are fixedly connected with the inner end part of the supporting frame; a first spring stretches and retracts in a supporting frame, then a push rod is synchronously driven to move backwards, the push rod pushes a square inserting rod to be separated from the interior of a first connecting plate, then a motor synchronously drives a sliding rod to be close to a limiting plate, and the square inserting rod keeps in the state of being away from the first connecting plate through attraction between the sliding rod and the limiting plate through a strong magnet; and the clean
