The invention discloses a ship underwater power system, and belongs to the technical field of ship power equipment. The ship underwater power system comprises a shell arranged in a ship body, and further comprises a jet engine which comprises a jet engine shell and a jet pipe, the jet engine shell is arranged at the bottom of the ship, a cavity is formed between the inner wall of the jet engine shell and the outer wall of the jet pipe and communicated with an annular jet opening, and a spiral guide plate is arranged on the inner wall of the jet pipe and communicated with the annular jet opening. One end of the spiral guide plate is arranged at the annular air nozzle; and the air supply mechanism is arranged in the shell, the air supply mechanism communicates with the cavity, and the air supply mechanism is used for supplying high-pressure air to the cavity. According to the underwater power system of the ship, the ship body is driven to advance without relying on rotating parts such as propellers which are in direct contact with the water body, and turbojet water flow can be formed in the air spraying pipe holes, so that the risk that the power system is blocked by garbage in the water body is reduced to the maximum extent, and the underwater power system has high reliability.

    本发明公开了一种船舶水下动力系统,属于船用动力设备技术领域。该船舶水下动力系统包括设于船体内的外壳,还包括:喷气引擎,包括喷气引擎外壳和喷气管,所述喷气引擎外壳设于船底,喷气引擎外壳内壁与喷气管外壁之间设有空腔,所述空腔连通有环形喷气口,喷气管内壁设有螺旋导流板,所述螺旋导流板一端设于环形喷气口处;供风机构,设于所述外壳内,所述供风机构与所述空腔连通,所述供风机构用于向空腔供给高压风。本发明的船舶水下动力系统,不依靠直接与水体接触的螺旋桨等转动部件驱动船体行进,且能在喷气管管孔内形成涡喷水流,从而最大限度的降低了动力系统被水体内垃圾堵塞的风险,具有较高的可靠性。
