Protection mechanism for aerator

An aerator protection mechanism relates to the technical field of aerator protection equipment and comprises a buoy ring and an aerator body, the aerator body is mounted on the inner side of the buoy ring, a mounting groove and a connecting groove are formed in the middle end and the outer end of the upper end face of the buoy ring respectively, and a protection cover is arranged on the inner wall of the connecting groove. A sliding block is arranged on the outer side face of the protective cover, a vertical groove and a transverse groove are formed in the upper end and the middle end of the inner wall of the connecting groove in a penetrating mode respectively, and one end of the sliding block is slidably connected to the interior of the vertical groove. Meanwhile, the aerator can be spirally mounted at the buoy ring through the arrangement of a mounting groove, a mounting seat and a connecting ring, so that the mounting and dismounting convenience of the aerator is improved, and the aerator is mainly applie
