The invention provides a direction-variable ultrasonic shaftless contra-rotating wheel rim propeller, and particularly relates to the technical field of underwater propellers. The device comprises a turning structure and a shaftless counter-rotating wheel rim annular propeller, the turning structure comprises a rotation assembly and a pitching assembly, the rotation assembly comprises a rotation joint, a rotation driving motor, a rotation connecting rod and a rotation rod, and the pitching assembly comprises a pitching joint, a pitching driving motor and a pitching rod. Each shaftless counter-rotating wheel rim annular propeller comprises a connecting rod and a guide pipe, a front rotating assembly, a rear rotating assembly and a piezoelectric ceramic assembly are arranged in an inner cavity of the guide pipe, the front rotating assembly and the rear rotating assembly are coaxially arranged and are each provided with a plurality of shaftless annular propellers, and the rotating directions of the front rotating assembly and the rear rotating assembly are opposite. The propeller is high in propelling efficiency, low in noise, high in integration level and high in reliability, light weight of the propeller is guaranteed while rotation control and pitching control of the propeller are achieved, and the adaptability of the propeller to the complex navigation environment is effectively improved.
