The invention discloses an opening and closing device for a ship telescopic propeller. The opening and closing device comprises a shell, a cover plate and a moving mechanism. The shell comprises an extending opening used for extending of the telescopic propeller. The cover plate has a closed state and an open state, the cover plate can cover the extending opening when in the closed state, and the extending opening can be exposed when the cover plate is in the open state; the moving mechanism is used for moving the cover plate in the first direction so that the cover plate can be switched between the closed state and the open state. The closed state and the open state are switched through movement of the cover plate, the open hole of the shell can be closed after the propeller retracts into the ship body, and the working efficiency of the propeller cannot be affected after the propeller stretches out of the ship body.
本申请公开了一种用于船舶伸缩式推进器的开合装置,包括外壳、盖板和移动机构。外壳包括伸出口,用于伸缩式推进器伸出;盖板具有闭合状态和开启状态,盖板位于闭合状态时能够覆盖伸出口,盖板位于开启状态时能够露出伸出口;移动机构用于沿着第一方向移动盖板,使得盖板能够在闭合状态和开启状态之间切换。本申请通过盖板的移动切换闭合状态和开启状态,既能在推进器缩回船体后封闭外壳的开孔,又不会在推进器伸出船体后影响推进器工作效率。
