The invention discloses an embedded manhole cover for a ship. The embedded manhole cover is arranged on the deck surface of a ship. The embedded manhole cover comprises a cover plate and a mounting base, wherein the cover plate is detachably connected with the mounting base; the mounting base is arranged on the edge of an opening of a manhole in a surrounding mode, a groove with an upper opening and a lower opening is formed in the outer surface of the mounting base, when the cover plate is fixedly connected with the mounting base, the cover plate is located in the groove, and the outer surface of the cover plate and the surface of the deck are located on the same plane. According to the embedded manhole cover disclosed by the invention, the cover plate-shaped concave area is constructed through an assembled seat ring structure; the cover plate is formed by cutting a whole steel plate, is installed in the concave area and is provided with the stepped through holes in a drilling mode, it is guaranteed that fastening bolts are not exposed out of the surface of the cover plate, the surface of the deck is flat, attractive and free of obvious concave structures after installation, meanwhile, the number of parts of the whole manhole cover is reduced, and machining and manufacturing are convenient.

本发明公开了一种埋入式船用人孔盖，其设置于船舶的甲板表面，该埋入式船用人孔盖包括盖板和安装底座，所述盖板和所述安装底座之间可拆卸连接，所述安装底座围设于人孔开口的边缘，所述安装底座的外表面形成一上下开口的凹槽，当所述盖板与所述安装底座之间固定连接时，所述盖板位于所述凹槽内，所述盖板的外表面与所述甲板的表面位于同一平面上。本发明的一种埋入式船用人孔盖通过装配的座圈结构构建盖板形状的凹陷区域，盖板使用整块钢板切割，安装在凹陷区域，盖板钻设阶梯形通孔，保证紧固螺栓不露出盖板面，安装完成后，甲板面平整，美观，无明显凹陷结构，同时减少了整个人孔盖零件数，加工制作方便。
