The invention relates to the technical field of ship propellers, and discloses a rim type motor driven contra-rotating propeller driving device which comprises a rim type propeller assembly and an equipment main output structure used for providing output power. The shell and the equipment main body structure are used for mounting the rim type propeller assembly; the first water guide ring is fixedly connected to the front side of the shell, the first water guide ring is used for guiding sucked water flow, the inner side of the first water guide ring is fixedly connected with a connecting rod, and the other end of the connecting rod is fixedly connected with a second water guide ring; and a shell cover. The first water guide ring and the second water guide ring are installed on the front side of the shell and connected through the connecting rod, so that water flow entering the shell is guided, meanwhile, the flow speed is increased under the influence of the shapes of the first water guide ring and the second water guide ring, the output water flow is guided and gathered in cooperation with the water gathering ring, and the water gathering efficiency is improved. Therefore, disordered water flow generated when the equipment works is reduced.

    本发明涉及船舶推进器技术领域,公开了一种轮缘式电机驱动的对转螺旋桨驱动装置,包括轮缘式螺旋桨组件,设备主要输出结构,用于提供输出动力;壳体,设备主体结构,用于安装轮缘式螺旋桨组件;导水环一,所述导水环一固定连接在所述壳体前侧,所述导水环一用于引导吸入的水流,所述导水环一内侧固定连接有连接杆,所述连接杆的另一端固定连接有导水环二;壳盖。通过在壳体前侧安装导水环一和导水环二并通过连接杆进行连接,由此来对进入壳体内部的水流进行引导,同时受到导水环一和导水环二的形状的影响,来加快流速,并配合聚水环来对输出的水流进行引导和聚集,以减少在设备工作时所产生的紊乱水流。
