The combined pump-jet propeller comprises a main body, a water inlet cavity is formed in the main body, and a water inlet hole is formed in the surface of the main body and communicates with the water inlet cavity. According to the combined pump-jet propeller, the auxiliary propellers are arranged and used for assisting work of the pump-jet propeller and enhancing propulsive force to a ship so as to accelerate the running speed of the ship, six to ten water inlet holes are formed, the water inlet holes can be prevented from being blocked at the same time, and the situation that work of the propeller is affected can be avoided; when the propeller moves, circulation is easily formed when water flow passes through the arc-shaped groove, water inlets of the water inlet holes in the arc-shaped groove are conveniently cleaned, a filter screen is installed in the water inlet holes, impurities can be prevented from entering the device and affecting work of the propeller, and the water flowing speed of the outer surface of the main body can be increased by starting the cleaning engine; the water inlet of the water inlet hole and the filter screen can be further cleaned conveniently, and the smoothness of the water inlet is ensured.

    本发明公开了一种组合式泵喷推进器,包括主体,主体的内部开设有进水腔,主体的表面开设有进水孔与进水腔相连通。该组合式泵喷推进器,通过设置辅助旋桨,用于辅助泵喷推进器的工作,加强对船舶的推进力,从而加快船舶行驶速度,进水孔开设有六到十个,可以防止进水孔同时被堵塞,影响推进器工作,进水孔的进水口处均设置有弧形凹槽,推进器在移动时,水流经过弧形凹槽时容易形成环流,方便对弧形凹槽中的进水孔的进水口进行清理,进水孔的内部安装有滤网,可以防止杂质进入装置内部,影响推进器的工作,通过启动清理发动机,可以加速主体外表面的水流动速度,方便进一步对进水孔的进水口和滤网进行清理,保证进水口通畅。
