The invention provides a power device for a ship, the ship and a power control method, relates to the technical field of power devices, and aims to solve the problem that a propeller, a propeller shaft or other parts are damaged by thrust of water when the propeller rotates in a complex underwater environment. The power device for the ship comprises a driving unit, a propelling unit and a control unit, a propeller shaft of the propelling unit comprises a first shaft section and a second shaft section which are sequentially connected, and a force sensing element is arranged between the first shaft section and the second shaft section. When the driving unit drives the propeller to rotate, the force sensing element outputs a force sensing signal to the control unit, and the control unit adjusts the output power of the driving unit according to the force sensing signal. The paddle shaft is designed into a two-section type, and the force sensing element is arranged at the joint of the first shaft section and the second shaft section, so that the output power of the driving unit can be adjusted when large underwater thrust is sensed, the thrust is reduced, and the thrust is prevented from damaging all parts.

    本申请提供一种用于船舶的动力装置、船舶及动力控制方法,涉及动力装置相关技术领域,用于解决螺旋桨在复杂的水下环境旋转时水的推力对螺旋桨、桨轴或其他部件造成损坏的问题。本申请中用于船舶的动力装置包括驱动单元、推进单元和控制单元,推进单元的桨轴包括依次连接的第一轴段和第二轴段,第一轴段和第二轴段之间设置有力感测元件。驱动单元驱动螺旋桨转动时,力感测元件向控制单元输出力感测信号,控制单元根据力感测信号调整驱动单元的输出动力。通过将浆轴设计为两段式,并在第一轴段和第二轴段的连接处设置有力感测元件的设计,本申请可以在感测到水下推力较大时对驱动单元的输出动力进行调整,以减小推力并防止推力对各部件造成损坏。
