The invention belongs to the technical field of electric generator maintenance, and aims at providing an electric generator stator coil corroding, blocking and cleaning integrated scheme. According tothe integrated scheme, welding plans of all welding parts in a mechanical cleaning path is made in advance, so that the phenomenon that a cleaning device is clamped in the mechanical cleaning processis prevented; a pipeline robot is used for bearing the cleaning device to crawl to the corresponding position, a spray gun body is driven to enter the end of an electric generator stator coil, and then a nozzle rotates by 360 degrees and sprays cleaning fluid seamlessly so as to thoroughly get through blocked stator coil braided wires; a complexing agent is used for multiple circulation to complex all corrosion products in the inner wall of a stator coil water loop to form complex products floating in the water loop, additional cleaning is conducted on mechanical cleaning; whether the corrosion products in the water loop are cleaned away thoroughly or not is checked; the water loop is maintained so as to avoid corrosion, so that by means of the integrated scheme, the corroding and blocking problems of the electric generator stator coil can be governed and prevented thoroughly and effectively.
