The invention discloses efficient underwater auxiliary propelling equipment and a stepping type underwater propelling system. The equipment comprises a buoy structure, a guide rod structure, a transmission device, a transmission shaft set and a propeller, wherein the transmission device comprises two pedals, a shell and an internal transmission mechanism, the internal transmission mechanism is located in the shell and comprises a fixing support, two transmission gears, two one-way bearings, two power gears and a power rotating shaft. When a user steps on one of the two pedals, the rotating directions of the two power gears are opposite, the rotating directions of the two transmission gears are opposite, the locking directions of the two one-way bearings are the same, one of the one-way bearings is locked so as to enable the power rotating shaft to synchronously rotate in the same direction along with one of the transmission gears to drive the propeller to rotate, and the other one-way bearing is not locked so as to enable the other transmission gear and the power rotating shaft to rotate oppositely. According to the invention, the movement efficiency is improved, a user is helped to save physical strength in the underwater navigation process, and the navigation speed is improved.

    本发明公开了一种高效水下辅助推进设备及踏步式水下推进系统。该设备包括浮筒结构、导杆结构、传动装置、传动轴套装以及螺旋桨。传动装置包括两个脚踏、外壳以及内部传动机构,内部传动机构位于外壳中且包括固定支架、两个传动齿轮、两个单向轴承、两个动力齿轮以及动力转轴。在使用者踩踏两个脚踏两者中的一者时,两个动力齿轮的旋转方向相反,两个传动齿轮的旋转方向相反,两个单向轴承的锁死方向相同,其中一个单向轴承锁死以使动力转轴跟随其中一个传动齿轮同向同步转动以带动螺旋桨转动,其中另一个单向轴承未锁死以使其中另一个传动齿轮与动力转轴反向相对转动。本发明提高运动效率,帮助使用者在水下航行过程中节省体力,提高航行速度。
