The invention provides a sea chest grating device which comprises a frame assembly used for being connected to a sea chest of a ship body, and the frame assembly is provided with a frame opening; the grille assembly is rotationally arranged at the frame opening and used for covering or opening the frame opening, the grille assembly comprises a first grille section and a second grille section, the first grille section is connected with the second grille section, and the rotating axis of the grille assembly is located between the first grille section and the second grille section. According to the sea chest grating device provided by the embodiment of the invention, on the basis of the arrangement, the resistance when the rotating grating is opened can be reduced, more labor can be saved when the grating assembly rotates, the first grating section and the second grating section can be rotated at the same time, force can be applied to the grating assembly more conveniently, two torques with the same rotating direction are provided for the grating assembly, and the grating assembly is more convenient to use. Therefore, the grille assembly can be opened or closed in a more labor-saving manner, an operator can operate the grille more conveniently, and the working efficiency can be improved.

    本公开提供了一种海底门格栅装置,包括:框架组件,用于连接于船体海底门,所述框架组件形成有框口;格栅组件,转动地设置于所述框口,用于覆盖或敞开所述框口,所述格栅组件包括有第一格栅段和第二格栅段,所述第一格栅段与所述第二格栅段相连接,所述格栅组件的转动轴线位于所述第一格栅段与所述第二格栅段之间。本公开实施例提出的海底门格栅装置,基于前述设置,可降低转动格栅开启时的阻力,可使格栅组件在转动时更为省力,且可同时转动第一格栅段和第二格栅段,更便于对格栅组件进行施力,为格栅组件提供两个转动方向相同的扭矩,从而可使格栅组件的打开或关闭更为省力,更便于操作人员对格栅进行操作,有利于提高工作效率。
