The invention relates to a double-spliced water jet propulsion inflow pipeline structure, which relates to the technical field of ship propulsion and the technical field of amphibious vehicle water propulsion, and comprises a public inflow seat, a first outflow elbow section and a second outflow elbow section, the public inflow seat is arranged on a ship bottom plate/a vehicle bottom plate, and a first outflow elbow and a second outflow elbow which are correspondingly connected with the first outflow elbow section and the second outflow elbow section respectively are arranged on the public inflow seat, so that remote water flow enters the public inflow seat along the ship bottom plate/the vehicle bottom plate and enters the first outflow elbow and the second outflow elbow in a split-flow mode. Each propeller obtains undisturbed inflow, and the problem that after two water-jet propellers are arranged on platforms such as a thin hull or an amphibious vehicle, due to the fact that the distance between the axes of the two devices is too small, the inflow disturbance phenomenon such as water robbing is caused in the working process, and then the operation performance of the water-jet propellers is affected is solved; and the application performance of the water-jet propeller on the platform is optimized.

    本发明涉及一种双拼式喷水推进进流管道结构,涉及船舶推进技术领域和两栖车辆水上推进技术领域,其包括公用进流座、第一出流弯管段、以及第二出流弯管段;公用进流座设于船底板/车底板,公用进流座上设有分别与第一出流弯管段和第二出流弯管段对应连接的第一出流弯管和第二出流弯管,以使远处水流沿船底板/车底板进入公用进流座,分流进入第一出流弯管和第二出流弯管。本发明使每台推进器获得未干扰的进流,解决在瘦型船体或两栖车辆等平台布置两台喷水推进器后,由于两台设备轴线间距过小,带来工作时抢水等进流干扰现象,进而影响喷水推进器运行性能问题,使喷水推进器在上述平台上的应用性能最优化。
