Water-jet propeller structure with high adaptability

The utility model relates to a high-adaptability water-jet propeller structure, which is characterized in that an inlet flow channel base is additionally arranged at an inlet of an inlet flow channel of a water-jet propeller in a right-angle installation mode, a floating stern board is additionally arranged at a stern board, and the inlet flow channel base and the water-jet propeller are connected through a high-strength bolt to realize thrust transmission. The axis of the water-jet propeller and the horizontal ship bottom of the ship body form an included angle of alpha degrees and are connected through an inlet flow channel base. A large-range continuous assembly plane of an original right-angle installation mode is changed into a single small-range assembly plane, the complexity of the installation process of the water-jet propeller is reduced, and the installation efficiency is improved. Direct connection of an impeller shaft and a main engine transmission shaft can be achieved by changing an included ang
