The invention relates to the field of sonar cavity measurement, and particularly provides a cavity measurement sonar device and method. A data acquisition short section; the control panels are installed on a shell of the data acquisition short section, the number of the control panels is M, M is a positive integer, the M control panels are distributed in the circumferential direction of the data acquisition short section at equal intervals, and the control panels can rotate in the radial direction of the data acquisition short section and are used for controlling the inclination angle of sound wave emission and receiving; an acoustic transducer; the hydraulic rod can perform telescopic motion relative to the data acquisition short section, and controls the control panel to expand or fall back in the radial direction of the data acquisition short section, so as to control the direction of the acoustic transducer; and the rotating motor is used for driving the data acquisition short section to rotate and measur
