Ultrasonic Cleaning Device with Adjustable Power for Submerged Structure

In order to meet the demand of video detection and fast repair of cracks on large submerged structure in different depths, this paper designed an ultrasonic cleaning device with adjustable power. A hydraulic pressure sensor collects the pressure signal in the place to be detected in real time and then sends it to the MCU to deal with. This device will adjust the duty ratio of ultrasonic signal synchronously according to different signal of depth, while making the ultrasonic cleaning head work under the rated output power, so as to avoid the surface damage of building material and achieve the balanced cleaning effect. By testing in different water depths from 0 to 4 m, this device can well meet the submerged cleaning demands. It provides a good reference to design ultrasonic cleaning devices for greater depth range underwater.
