The invention discloses a water jet propulsion variable nozzle structure which sequentially comprises a guide vane body nozzle, the guide vane body nozzle sequentially comprises a flange, a flow channel and a cavity, an inflatable inflation ring is arranged in the cavity, and an inflation inlet of the inflation ring is communicated with an inflation mechanism through a threaded hole in the cavity. According to the variable nozzle structure of the water jet propulsion pump, the nozzle diameter can be freely adjusted within a certain range, a ship can adopt different nozzle diameters under the conditions of the resistance peak value, the high speed and the cruising speed, it is guaranteed that all kinds of working sections can complete the overall design target, ship energy saving is achieved, and the ship performance is improved. And the efficient operation range of the water-jet propulsion pump is widened.

    本发明公开了一种喷水推进可变喷口结构,其依次包括导叶体喷口,所述导叶体喷口依次包括法兰、流道、腔体,所述腔体内设有可充气的充气圈,充气圈的充气口通过腔体上的螺纹孔与充气机构连通。本发明通过一种喷水推进泵可变喷口结构可以实现喷口直径在一定范围内任意调节,船舶可以在阻力峰值和高速以及巡航速度条件下分别采用不同的喷口直径,保证各种工作剖面均能完成总体设计目标、实现船舶节能,并拓宽了喷水推进泵高效运行范围。
