An external ducted propeller propelling device comprises a hydraulic power unit arranged in a ship body, a hydraulic motor arranged outside the ship body and a ducted propeller assembly, the top of the ducted propeller assembly is fixedly connected with the bottom of the ship body, one end of the ducted propeller assembly is fixedly connected with an output shaft of the hydraulic motor, a first opening of the hydraulic motor is communicated with an oil outlet of the hydraulic power unit through a first cabin penetrating guide pipe, a second opening of the hydraulic motor is communicated with an oil inlet of the hydraulic power unit through a second cabin penetrating guide pipe, and sealing joints are arranged between the first cabin penetrating guide pipe and the ship body and between the second cabin penetrating guide pipe and the ship body. According to the device, a traditional cabin penetrating transmission shaft system is omitted, the two cabin penetrating guide pipes are adopted for connecting the hydraulic power unit and the hydraulic motor which are located inside and outside the ship body respectively, the sealing performance with the ship body is good, selection of the installation position is more flexible, the requirement for the installation space is small, and in addition, the installation difficulty is reduced.

    一种外置式导管桨推进装置,包括设置在船体内部的液压动力单元、设置在船体外部的液压马达和导管桨总成,导管桨总成的顶部与船体的底部固定连接,导管桨总成的一端与液压马达的输出轴固定连接,液压马达的一号口通过一号穿舱导管与液压动力单元的出油口相连通,液压马达的二号口通过二号穿舱导管与液压动力单元的进油口相连通,一号穿舱导管与船体之间、二号穿舱导管与船体之间均设置有密封接头。本装置取消了传统穿舱传动轴系,采用2根穿舱导管连接分别位于船体内外的液压动力单元和液压马达,不仅与船体的密封性好,而且使安装位置的选取更灵活、对安装空间的要求较小,另外,降低了安装难度。
