The invention relates to the technical field of ship drag reduction, in particular to an air jet hole water blocking device suitable for a ship air layer drag reduction system and a ship. The ship airlayer drag reduction system comprises an air cavity. The air spraying hole is formed in the bottom of the ship body, communicates with the air cavity and is used for spraying out airflow; the air jethole water blocking device comprises an air jet hole water blocking device arranged in the air cavity and movably connected with a bottom plate of the ship body. And the driving mechanism is arrangedin the ship body and located on the outer side of the air cavity, and the output end of the driving mechanism extends into the air cavity and is connected with the air spraying hole water blocking device so as to drive the air spraying hole water blocking device to open or block the air spraying hole. Through the arrangement of the air spraying hole water blocking device, the air spraying hole can be blocked when the ship air layer resistance reducing system stops working, seawater is prevented from carrying a large number of marine organisms and silt to enter the air cavity, and therefore the air spraying hole and the air cavity are prevented from being blocked, and seawater can be prevented from entering the air cavity to corrode the air cavity and a bottom plate of a ship body.

    本发明涉及船舶减阻技术领域,尤其涉及一种适用于船舶气层减阻系统的喷气孔阻水装置及船舶。该船舶气层减阻系统包括气腔;喷气孔,设置于船体底部且与所述气腔连通,用于喷出气流;所述喷气孔阻水装置包括:喷气孔阻水器,设置于所述气腔内且与所述船体的底板活动连接;及驱动机构,设置于所述船体内且位于所述气腔外侧,所述驱动机构的输出端伸入所述气腔内且与所述喷气孔阻水器连接,以驱动所述喷气孔阻水器打开或遮挡所述喷气孔。通过设置喷气孔阻水器,可以在船舶气层减阻系统停止工作时,遮挡喷气孔,避免海水携带大量海生物和泥沙进入气腔内,从而避免喷气孔和气腔堵塞,也可以避免海水进入气腔内腐蚀气腔和船体的底板。
