The invention provides a ship propeller (100), a ship (200) and a control method of the ship propeller (100). The marine propeller (100) comprises: a frame (1) provided with an underwater suspension part (11), the underwater suspension part (11) being provided with a driving rotating shaft (12); the propeller (2) is connected with the driving rotating shaft (12); the guide pipe (3) is connected with the rack (1), and at least part of the guide pipe (3) can move relative to the propeller (2) so as to present a flow guide form or an open form; when the guide pipe (3) is in the flow guide state, the guide pipe (3) surrounds the propeller (2) and is coaxial with the propeller (2). When the guide pipe (3) is in the open state, the guide pipe (3) is located on the water surface, and at least part of the guide pipe (3) forms a wave suppression structure. By arranging the guide pipe (3) capable of moving relative to the propellers (2), the position of the guide pipe (3) can be adjusted according to the rotating speeds of the different propellers (2) so as to form a flow guide form and an open form, so that the propelling structure can be quickly switched between a ducted propeller and a common propeller; therefore, the ship propeller (100) can be matched with different load conditions in time, and the propelling efficiency of the ship propeller (100) is greatly improved.

    提供了一种船用推进器(100)、船舶(200)及船用推进器(100)的控制方法。船用推进器(100)包括:机架(1),设有水下悬置部(11),水下悬置部(11)设有驱动转轴(12);螺旋桨(2),与驱动转轴(12)连接;导管(3),与机架(1)连接,导管(3)的至少部分可相对螺旋桨(2)活动,以呈现导流形态或开放形态;导管(3)处于导流形态时,导管(3)环绕螺旋桨(2)周围并与螺旋桨(2)同轴设置;导管(3)处于开放形态时,导管(3)位于水面上,且至少部分形成压浪结构;通过设置可相对螺旋桨(2)活动的导管(3),导管(3)可以根据不同螺旋桨(2)的转速调整位置以形成导流形态和开放形态,使推进结构在导管螺旋桨和普通螺旋桨之间进行快速切换,从而使船用推进器(100)及时匹配不同的载重情况大幅提高船用推进器(100)的推进效率。
