The invention discloses a ship energy-saving propelling device, and relates to the technical field of ships. Comprising a fixing frame, a supporting rod, a motor, a rotating shaft, a propelling impeller and a net-shaped protective cover, and a propelling mechanism is arranged on the outer wall of the rotating shaft; the pushing mechanism comprises a rhombic plate and an arc-shaped push rod, a radial sliding groove is formed in a circular screen plate of the net-shaped protection cover in the circle center direction, a sliding block in sliding fit with the radial sliding groove is arranged on the side wall of the arc-shaped push rod, a first spring is arranged between one side of the sliding block and the inner wall of one side of the radial sliding groove, and a circular block is arranged at the end, away from the arc-shaped push rod, of the sliding block. The circular block is located on the inner side of the circular screen plate on the net-shaped protective cover and corresponds to the side edge of the rhombic plate. The pushing mechanism is driven by the rotating shaft to rotate, finally the arc-shaped push rod is driven to move outwards, and then flexible objects and the like covering the net-shaped protection cover are pushed away through the arc-shaped push rod, so that the flexible objects and the like are prevented from covering the surface of the net-shaped protection cover, the resistance of the propelling device is prevented from being increased, and the propelling speed is reduced.

    本发明公开了一种船舶节能推进装置,涉及船舶技术领域。包括:固定框、支撑杆、电机、转轴、推进叶轮、以及网状保护罩,转轴的外壁设置有推动机构;推动机构包括菱形板、以及弧形推杆,网状保护罩的圆形网板上沿圆心方向开设有径向滑槽,弧形推杆的侧壁设置有与径向滑槽滑动配合的滑块,滑块的一侧与径向滑槽的一侧内壁之间设置有弹簧一,滑块远离弧形推杆的一端设置有圆块,圆块位于网状保护罩上圆形网板的内侧且与菱形板的侧边对应。通过转轴带动推动机构转动,最终会驱使弧形推杆向外移动,进而通过弧形推杆将覆盖到网状保护罩上的柔性物体等推开,从而避免柔性物体等覆盖到网状保护罩表面,避免增加推进装置的阻力、降低推进速率。
