The invention relates to a hand and foot combined front-back reciprocating intermittent motion type underwater bicycle which is characterized in that reciprocating motion of two legs and two arms cangive full play to the maximum strength of a human body so as to improve the running speed of the underwater bicycle to the maximum extent. The underwater bicycle has three thrust transmission implementation modes of 1, backwards spraying pressure water to generate a thrust, wherein a transmission route includes pedals (handles), a transmission rod, a piston, a water pressing pipe and a water outlet; 2, backwards spraying a gas-water mixture to generate the thrust, wherein the transmission route is pedals (handles), the transmission rod, the piston, a pneumatic pipe, a gas-water connecting pipe, the water pressing pipe and the water outlet; and 3,rotating a propeller to discharge a water flow to generate a backward thrust, wherein the transmission route is the pedals (handles), a transmission belt, a belt pulley, a main transmission shaft, the propeller, a diversion elbow and the water outlet. In addition, by adjusting a buoyancy device, a frame and a transmission structure, the human body can be located on the water surface to control the bicycle, and the application range of the bicycle is widened.
一种手脚并用前后往复间歇运动式水中自行车,其特点是双腿、双臂的往复运动可以充分发挥人体的最大力量,以最大限度的提高水中自行车行驶速度。该水中自行车有三种推力传动实现方式:一、向后喷射压力水产生推力,传动路线为脚蹬(手柄)、传动杆、活塞、压水管、出水口;二、向后喷射气水混合物产生推力,传动路线为脚蹬(手柄)、传动杆、活塞、气压管、气水连接管、压水管、出水口;三、螺旋桨旋转排出水流产生向后推力,传动路线为脚蹬(手柄)、传动带、皮带轮、主传动轴、螺旋桨、导流弯管、出水口。本发明还可以通过调整浮力装置、框架、传动结构,使人体处于水面之上对其进行操控,以增加其适用范围。
