The invention discloses a novel water jet propulsion device for small and medium-sized ships. The device comprises a water inlet cabin, a cleaning motor, a first connecting rod, a cleaning brush, a mounting shell, a sand prevention net, a mounting groove, a guide column, a transmission gear, an impeller ring, an impeller, a transmission shell, a transmission column, a first gear, a transmission motor, a sealing ring, a connecting block, an injection pipe, a steering gear, a second gear, a second connecting rod, a steering motor, a guide column groove and a spray head, and the mounting groove is formed in one side of the mounting shell. According to the device, kinetic energy provided by the device is increased through the shaftless design of the impeller ring, the transmission distance is shortened and the transmission stability is improved through the transmission motor arranged on one side, the impeller ring is convenient to disassemble and replace the impeller through the formed mounting groove, the labor intensity of overhaul and maintenance is relieved, the water inlet is prevented from being blocked through the cleaning brush. Meanwhile, the sand prevention net prevents the impeller from being damaged by sand grains, the service life of the device is prolonged, the heading direction is changed by adjusting the direction of the spray head through the arranged steering motor, and energy consumption of reverse advancing is reduced.

    本发明公开了新型中小型船舶喷水推进装置,包括进水舱、清理电机、第一连杆、清理刷、安装壳、防砂网、安装槽、导柱、传动齿轮、叶轮环、叶轮、传动壳、传动柱、第一齿轮、传动电机、封口环、连接块、喷射管、转向齿轮、第二齿轮、第二连杆、转向电机、导柱槽和喷头,所述安装壳的一侧开设有安装槽,本发明,利用叶轮环的无轴设计,增大了装置所能提供的动能,在一侧设置的传动电机缩短了传动距离,提高了传动稳定性,通过开设的安装槽,便于拆卸叶轮环更换叶轮,减轻了检修维护的劳动强度,通过清理刷防止进水口堵塞,同时防砂网防止砂粒损伤叶轮,延长了装置的使用寿命,通过设置的转向电机调整喷头的方向来改变航向,减少了反向行进的能耗。
