The invention relates to a doorsill-free sliding watertight door, and belongs to the technical field of ships. The doorsill-free sliding watertight door comprises a door body, a door frame and a frame, the door body is connected with the frame, and when the door body is closed, the bottom of the door body is pressed on a deck of a ship body through a sealing strip; a lifting oil cylinder is arranged on the frame, after the door body is lifted upwards, the frame is fixed on a ship body through a hydraulic bolt, a movable oil cylinder used for opening or closing the door body is arranged on the door body, the other end of the movable oil cylinder is fixed on the frame, and the door body slides towards two sides or the middle along a horizontal guide rail on the frame. As the door body can slide along the guide rail on the frame, the sealing strip at the bottom of the door body is pressed on the deck through downward pressure formed by the locking bolt, the door body is lifted upwards under the action of the lifting oil cylinder, the door body is lifted upwards firstly and then slides horizontally, a doorsill is not needed at the bottom, cargoes and vehicles can enter and exit very conveniently, and the service life of the door body is prolonged. Meanwhile, watertightness can be guaranteed, the structure is simple, and manufacturing and installation are convenient.

    本发明涉及一种无门槛滑动水密门,属于船舶技术领域。其结构包括门体、门框及框架,门体与框架相连接,门体关闭时门体的底部通过密封条压紧在船体的甲板上;所述框架上设有提升油缸,门体向上提升后,框架通过液压插销固定在船体上,门体上设有用于门体开启或关闭的移动油缸,移动油缸的另一端固定在框架上,所述门体沿框架上的水平导轨向两侧或中间滑动。本发明由于门体可以沿框架上的导轨滑动,通过锁紧插销形成的下压力使门体底部的密封条压紧在甲板上,门体在提升油缸的作用下向上提升,完成门体先向上提升,在进行水平滑动的动作,这样底部无需门槛,货物、车辆进出极其便利,同时还能保证水密,结构简单,制造及安装方便。
