The invention discloses a small water-jet propeller based on hydraulic speed regulation. The small water-jet propeller comprises a water-jet propeller body, a speed control part and a hydraulic cylinder, the speed control part is fixedly connected with a hydraulic rod of the hydraulic cylinder, the speed control part is provided with a liquid distribution bin with an opening in one end, the bottom of the liquid distribution bin is communicated with a plurality of liquid distribution pipes, each liquid distribution pipe is bent towards the opening direction of the liquid distribution bin, and the axis of the tail end of each liquid distribution pipe is parallel to the axis of the opening direction of the liquid distribution bin; and the hydraulic cylinder controls the opening of the liquid separation bin to be opposite to or separated from the water injection nozzle of the water-jet propeller body. According to the propeller, power is provided for speed adjustment of a ship body and reversing movement through the hydraulic system, the hydraulic cylinder adjusts the position of the speed control piece, the water flow direction of water sprayed out of the water spraying propeller body is changed through the liquid distribution pipe of the speed control piece, resistance is generated, and powerful and stable adjustment of the water spraying propeller can be achieved; and therefore, the forward speed of the ship body is stably adjusted.

    本发明为一种基于液压调速的小型喷水推进器,包括喷水推进器本体、速度控制件和液压缸;速度控制件与液压缸的液压杆固连,速度控制件具有一端开口的分液仓,分液仓的底部连通多个分液管,每个分液管均朝向分液仓的开口方向折弯,且分液管末端的轴线与分液仓的开口方向轴线平行;由液压缸控制分液仓的开口与喷水推进器本体的喷水口相对或分离。该推进器通过液压系统为船体的速度调节、实现倒车运动提供动力,液压缸调节速度控制件的位置,使喷水推进器本体喷出的水经过速度控制件的分液管改变水流方向,产生阻力,可以实现对喷水推进器有力且稳定的调节,进而对船体前行时的速度进行稳定调节。
