Water-saving flushing device for cooling fins of air cooling island

The utility model discloses a water-saving flushing device for radiating fins of an air cooling island, which comprises a track arranged above a finned tube in parallel, a walking frame capable of longitudinally moving along the track, a pulley capable of moving along the walking frame and a spray head group arranged on the pulley, and the spray head group comprises a second spray head and first spray heads arranged on two sides of the second spray head. The first spray head is connected with a demineralized water pipeline, and the second spray head is connected with a compressed air pipeline. Dirt cleaning mainly depends on washing of the compressed air on the dirt, and the demineralized water is only used for wetting the dirt and assisting cleaning, so that a large amount of high-pressure demineralized water is not needed, the demineralized water is saved, meanwhile, the demineralized water falling on electrical equipment below the finned tube is reduced, and meanwhile, a high-pressure water pump for convey
