The invention relates to the technical field of ship propeller parts, in particular to a ship propeller flow guide device which comprises a propeller assembly and a flow guide cover, the periphery of the propeller assembly is sleeved with the flow guide cover, fixing supporting plates are vertically and symmetrically fixed to the outer ring face of the flow guide cover, and T-shaped sliding blocks are slidably arranged in T-shaped sliding grooves. Hinge blocks are fixed to the front end faces of the symmetrical fixing supporting plates, the fixing shaft rod is sleeved with a connecting soft plate, the two ends of the connecting soft plate are connected with flow guide plates, a supporting rod is arranged between the T-shaped sliding blocks which are vertically symmetrical, a rotating shaft rod is rotationally arranged in the positioning groove, the rotating shaft rod is sleeved with a supporting push plate, and the hinge blocks are fixed to the upper inner side wall and the lower inner side wall of the two flow guide plates. A rotating shaft rod is rotationally arranged on the hinge block and connected with the other end face of the supporting push plate, and an electric push rod is arranged on the rear end face of the fixed supporting plate. According to the invention, the resistance generated when the propeller assembly runs in sludge can be reduced, so that the sailing stability of a ship in a sludge channel can be improved.
本发明涉及船舶螺旋桨部件技术领域,具体为一种船舶螺旋桨导流装置,包括螺旋桨组件和导流罩,且螺旋桨组件外围套设有导流罩,导流罩的外圈面上下对称固定有固定支板,T型滑槽内滑动设置有T型滑块,对称的固定支板前端面固定有铰接块,固定轴杆套接有连接软板,且连接软板的两端均连接有导流板,上下对称的T型滑块之间设置有支撑杆,定位槽内转动设置有转轴杆,且转轴杆上套接有支撑推板,两个导流板的上下内侧壁固定有铰接块,且铰接块上转动设置有转轴杆,且该转轴杆与支撑推板的另一端面连接,固定支板的后端面设置有电动推杆;本发明能够降低螺旋桨组件在淤泥中运行时所产生的阻力,从而能够提高船舶在淤泥航道中航行的稳定性。
