The invention discloses a manufacturing method of a ship sea chest grating.The method comprises the following steps: S10, determining the position and the size of a sea chest in an outer plate three-dimensional diagram, and obtaining a sea chest opening area; S20, selecting an opening area of a grating structure in the outer plate three-dimensional diagram to obtain a grating opening area, enabling the grating opening area to be located on a hull outer plate corresponding to the sea chest opening area, and determining the thickness of the grating structure; S30, obtaining a three-dimensional diagram of the sea chest grating according to the sea chest opening area, the grating opening area and the thickness of the grating structure; and S40, cutting water inlet holes in the hull outer plate according to the three-dimensional diagram of the sea chest grating, so that the grating structure is formed on the hull outer plate. The matching degree of the sea chest grating and the hull outer plate can be improved, and repeated machining of the hull outer plate is reduced.

    本发明公开一种船舶海底门格栅的制造方法及船舶海底门格栅,包括以下步骤:步骤S10、在外板三维图中确定海底门的位置和尺寸,得到海底门开设区域;步骤S20、在外板三维图中选取格栅结构的开设区域,得到格栅开设区域,并使格栅开设区域位于海底门开设区域对应的船体外板上,以及确定格栅结构的厚度;步骤S30、根据海底门开设区域、格栅开设区域和格栅结构的厚度获得海底门格栅的三维图;步骤S40、根据海底门格栅的三维图在船体外板上切割进水孔,以使在船体外板上形成格栅结构。其能够提高海底门格栅与船体外板的匹配度,以及减少船体外板的重复加工。
