Novel device capable of replacing aeration pipe without cutting off water

The utility model belongs to the technical field of sewage treatment, and particularly relates to a novel device capable of replacing an aeration pipe without cutting off water, which comprises an aeration tank, two sides of the aeration tank are symmetrically connected with slide rails, an overhauling device is slidably connected onto the slide rails and comprises slide blocks slidably connected with the slide rails, and an overhauling table is positioned above the slide blocks and stretches across the aeration tank. Hinge type lifters are installed on the front side and the rear side of the aeration tank, the connecting ends of the two hinge type lifters are connected with the front end and the rear end of the aerator body respectively, the aerator body in the aeration tank is driven by the hinge type lifters to be lifted to the height flush with the overhaul stand, and lifting overhaul is facilitated; the overhaul stand is located above the sliding block and stretches across the aeration tank to be matched
