The invention relates to the technical field of underwater propellers, and discloses a small sightseeing boat underwater propeller which comprises a water inlet, a tubular piston device is fixedly connected to one side of the water inlet, a jet orifice is fixedly connected to the other side of the tubular piston device, and a propelling device is movably connected to the middle of the tubular piston device. A rudderstock is movably installed in the middle of the propelling device, a deflection channel is communicated between the jet orifices, and deflection rods are movably installed at two ports of the deflection channel. The rudder stock drives the center shaft to rotate to enable the center wheel to rotate so as to drive the connecting shaft to rotate, the push rod arm can rotate aroundthe center of the planet wheel to enable the connecting shaft and the pipe clamp set to do reciprocating motion in the horizontal direction after being connected, and then the valve mounting shaft ismatched with the hinge valve; water flow at the water inlet is compressed and pushed into the jet orifice, and the problem of cavitation of the back face of the spiral impeller due to the fact that the spiral impeller pushes the water flow is solved.

    本发明涉及水下推进器技术领域,且公开了一种小型游船水下推进器,包括进水口,所述进水口的一侧固定连接有管式活塞装置,所述管式活塞装置的另一侧固定连接有喷射口,所述管式活塞装置的中间活动连接有推进装置,所述推进装置的中间活动安装有舵杆,所述喷射口之间连通有偏转通道,所述偏转通道的两端口活动安装有偏转杆。本发明通过舵杆驱动中心轴转动使得中心轮旋转从而带动连接轴转动,推杆臂可围绕行星轮的中心转动使得连接轴与管夹组连接后在水平方向做反复运动,再由阀门安装轴与合页阀门的配合,实现了将进水口的水流压缩推进到喷射口中,解决了由螺旋叶轮推进水流造成螺旋叶轮的背面汽蚀的问题。
