Abstract

The present invention discloses an adjustable underwater robot cavitation jet cleaning device. The cleaning device is equipped with an electric regulating valve to control the flow rate of liquid sprayed from the cavitation nozzle. The first and second steering gears can freely control the cavitation gun to rotate left and right and in pitch, respectively, and the flow rate of the cavitation gun and the flow rate of the balance valve cylinder can be controlled. The cavitation bracket can adjust the vertical and horizontal position of the cavitation gun, thereby adjusting the distance between the cavitation gun and the cleaning surface, thereby achieving more thorough and accurate cleaning, realizing large-scale detection and cleaning operations, and improving operational efficiency. When the underwater robot is in a stable position, the cleaning device expands the cleaning range and improves the accuracy of the cleaning position. It can also precisely control the recoil force, reduce the difficulty of operation, and thus improve the efficiency of underwater cleaning accuracy.
