The invention discloses an automatic flow control water-dripping maintenance system comprising a water bucket and a transducer. The water bucket is disposed at a high position as a water storage device such that water in the water bucket produces water pressure; under the action of the water pressure, the water in the water bucket jets into a water tank. The transducer is disposed at the bottom of the water tank connected to the water bucket, converts electric energy into mechanical energy and emits ultrasonic wave into water; under the action of the ultrasonic wave, ultrafine particles are produced at the water surface in the water tank, thereby forming water spray particles; and the water spray particles exchange heat and humidity with flowing air to thereby realize water-dripping maintenance for concrete. The purpose of improving the maintenance quality is achieved.
