The invention relates to the field of ship engineering structure design, and discloses a telescopic seawater suction device suitable for a bubble drag reduction ship, the telescopic seawater suction device comprises a seawater tank, a lifting cylinder and a lifting assembly, the seawater tank is arranged between the inner bottom and the outer bottom of a ship body, a through hole is formed in the seawater tank, the lifting cylinder is arranged in the seawater tank, and the two ends of the lifting cylinder penetrate through the through hole; the lifting cylinder can slide in the seawater tank, a plurality of round holes are formed in the side wall of the lifting cylinder, the lifting assembly is arranged above the inner bottom of the ship body and connected with the lifting cylinder, a bottom grating is arranged at the bottom, located on one side of the outer bottom of the ship body, of the lifting cylinder, and a seawater short pipe is arranged on the side wall of the seawater tank. According to the marine lifting device, the lifting cylinder can extend out of the bottom of the ship by a certain distance according to needs, and air films or bubbles on the surface of the ship body are prevented from entering the seawater header pipe through a sea chest during sailing, so that the normal operation of related equipment is prevented from being influenced by the air films or the bubbles.

    本发明涉及船舶工程结构设计领域,公开了一种适用于气泡减阻船舶的伸缩式海水吸入装置,包括海水箱、升降筒和升降组件,所述海水箱设在船体内底和船体外底之间,所述海水箱上设有通孔,所述升降筒设在海水箱中且两端穿过通孔,所述升降筒可在海水箱中滑动,所述升降筒侧壁上设有多个圆孔,所述升降组件设在船体内底上方且与升降筒连接,所述升降筒位于船体外底一侧的底部上设有底部格栅,所述海水箱侧壁上设有海水短管,所述海水短管穿出海水箱侧壁并与海水总管连接,本发明可根据需要将升降筒伸出船底一定距离,避免航行时船体表面的气膜或气泡时通过海底门进入海水总管,从而防止其影响相关设备正常作业。
