The invention discloses a variable-caliber rotatable nozzle and a water spraying propulsion system. The variable-caliber rotatable nozzle comprises multiple sections of flow guide pipes, a rectifying pipe and a variable-caliber nozzle body. The multiple sections of flow guide pipes are sequentially and rotatably connected, the first section of flow guide pipe is connected with an outlet of the water jet propulsion system, and the tail section of flow guide pipe is sequentially connected with the rectifying pipe and the variable-caliber nozzle. Due to the fact that the multiple sections of flow guide pipes are not all arranged along the same axis, the direction of the variable-caliber nozzle can be changed by rotating the flow guide pipes so as to change the direction of outlet jet flow. In addition, the size of the jet flow can be adjusted by adjusting the size of the outlet of the variable-caliber nozzle, so that the adjustment and control of the water jet propulsion system are more accurate, and the control efficiency and the convenience degree of the ship are effectively improved.

    本发明公开了一种变口径可旋转喷嘴及喷水推进系统,包括多段导流管、整流管和变口径喷嘴;多段导流管依次可转动连接,首段导流管与喷水推进系统的出口连接,末段导流管与整流管和变口径喷嘴依次连接。由于多段导流管非全部沿同一轴线布置,因此通过旋转导流管可以改变变口径喷嘴的朝向,以改变出口射流的方向;另外通过对变口径喷嘴出口大小的调节还可以调整射流大小,使喷水推进系统的调节和控制更加精准,有效提高了船舶的操纵效率和便捷程度。
