The invention discloses a water-jet propulsion pump device with a telescopic water inlet flow channel and an implementation method thereof, and belongs to the field of ship engineering. The device comprises a water-jet propulsion pump and a water inlet flow channel. The water inlet flow channel comprises a near-nozzle water inlet flow channel and a near-water inlet flow channel, the near-nozzle water inlet flow channel is located at a water inlet end of the water-jet propulsion pump, and the near-water inlet flow channel is movably connected with a ship plate; the device is provided with a telescopic water passing part, one end of the telescopic water passing part is fixedly connected with a near-nozzle water inlet flow channel, and the other end of the telescopic water passing part is connected with the near-water inlet flow channel; and the telescopic water passing part moves upwards or downwards in the near-water inlet flow channel so that the water inlet flow channel is telescopic,a draft T' reaches a proper range, the stable operation of the water-jet propulsion device is realized, and the water-jet propulsion pump device and the method have wide market and application prospects in the design and operation of propulsion ships and high-speed boats.

    一种进水流道可伸缩的喷水推进泵装置及其实现方法,属于船舶工程领域。包括喷水推进泵以及进水流道,其特征是,所述进水流道包括近喷口进水流道、近进水口进水流道,所述近喷口进水流道位于喷水推进泵的进水口端,所述近进水口进水流道与船板活动连接;该装置设有可伸缩过水部件,所述可伸缩过水部件一端与近喷口进水流道固定连接,另一端与近进水口进水流道套接;通过使可伸缩过水部件在近进水口进水流道内上行或下行,实现进水流道的可伸缩,使吃水深度T'达到适当范围,实现喷水推进装置稳定运行,在推进船舶、高速艇的设计与运行中有广阔的市场和应用前景。
