The invention relates to the technical field of ship drag reduction, in particular to an air injection water-blocking sealing device suitable for a ship air layer drag reduction system and a ship. Theship air layer drag reduction system comprises an air cavity. The air spraying holes are formed in a bottom plate of the ship body, communicate with the air cavity and are used for spraying out air flow; the air injection water-blocking sealing device comprises a sealing plug arranged in the air cavity; and the driving mechanism is arranged in the ship body and located at the top of the outer side of the air cavity, the output end of the driving mechanism extends into the air cavity and is connected with the sealing plug, and the driving mechanism can drive the sealing plug to ascend and descend so as to open or seal the air spraying hole. By arranging the sealing plug, the air injection hole can be sealed when the ship air layer drag reduction system stops working, seawater is preventedfrom carrying a large number of marine organisms and silt to enter the air cavity, and therefore the air injection 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阻水密封装置及船舶。该船舶气层减阻系统包括气腔;喷气孔,设置于船体的底板上且与所述气腔连通,用于喷出气流;所述喷气阻水密封装置包括:密封塞,设置于所述气腔内;及驱动机构,设置于所述船体内且位于所述气腔外侧顶部,所述驱动机构的输出端伸入所述气腔内且与所述密封塞连接,能驱动所述密封塞升降以打开或密封所述喷气孔。通过设置密封塞,可以在船舶气层减阻系统停止工作时密封喷气孔,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。
