The invention provides a sea chest grille device. The sea chest grille device comprises a chest grille, a hinge eye plate and a hinge support. And the outer edge of the door grating is in zero-clearance fit with the inner ring of the sea chest. And a mounting hole is formed in the hinge eye plate. And when the hinge eye plate is turned over relative to the hinge bracket, the door grid is driven to turn over by taking the hinge eye plate as a hinge point. The hinge support is provided with a connecting long hole, the hinge eye plate is connected with the hinge support through a fixing piece inserted in the mounting hole and the connecting long hole, and the hinge eye plate can drive the door grating to be adjusted in the thickness direction of the sea chest. On the premise that the gap between the sea chest grating and the seawater inlet is reduced, the situation that the chest grating collides with a ship body in the opening or closing process, and the ship body is damaged is prevented. And after the door grid is closed, the outer side face of the door grid is flush with the outer side of the ship body, the outer side part of the ship body is not provided with any protruding part, and the water flow resistance of the ship body can be reduced.

    本申请提供一种海底门格栅装置,包括门格栅、铰接眼板和铰接支架。门格栅的外边缘与海底门的内圈之间无间隙配合。在铰接眼板上设置有安装孔。在铰接眼板相对铰接支架翻转时带动门格栅以铰接眼板为铰接点翻转。铰接支架上设有连接长孔,铰接眼板通过插设在安装孔和连接长孔的固定件与铰接支架连接,铰接眼板可带动门格栅在海底门的厚度方向上进行调节。本申请在减小海底门格栅与海水进口之间间隙的前提下,防止门格栅在打开或者关闭过程中与船体发生碰撞,对船体造成损坏。并且在关闭门格栅后,门格栅的外部的侧面与船体的外侧平齐,船体的外侧部分无任何突出部位,可以降低船体的水流阻力。
