The invention discloses a turnover type shaftless propeller which comprises a fixed base support, a propeller body and a propeller body. The rim propeller is rotationally connected to the fixed base support, the rim propeller is provided with two rotationally connected state positions based on the fixed base support, one rotationally connected state position is a reset state position, the radial plane of the rim propeller in the reset state position is parallel to the plane in the advancing direction, and the other rotationally connected state position is a propelling state position; a preset angle is formed between the radial plane of the rim propeller in the propelling state position and the plane in the advancing direction; a battery and a control circuit which are electrically connected are arranged in the machine body structure; and a battery and a control circuit in the machine body structure are electrically connected with the rim propellers. The technical problems that in the prior art, an underwater thruster is large in size and inconvenient to carry, thrust is generated through a propeller with a shaft, the underwater thruster can be wound when encountering foreign matter such as ropes, and the overall function safety and stability are poor are solved.
本发明公开了一种可翻转式无轴推进器,包括:固定基座支架;和轮缘推进器,转接于固定基座支架,且轮缘推进器基于固定基座支架具有两个转接状态位,其中一个转接状态位为复位状态位,复位状态位的轮缘推进器的径向平面与前进方向的所处平面相平行,另一个转接状态位为推进状态位,推进状态位的轮缘推进器的径向平面与前进方向的所处平面之间具有预定角度;以及机体结构,内部配置有相电连接的电池和控制电路;机体结构内部的电池和控制电路与轮缘推进器之间电性连接。解决了现有技术中的水下推进器体积较大,不便于携带,且通过有轴螺旋桨产生推力,遇到绳子等异物会发生缠绕,整体功能安全稳定性较差的技术问题。
