The invention provides a watertight hatch cover. The watertight hatch cover comprises a cover plate, a cover surrounding sill, a hinge assembly and a toggle clip assembly. A plurality of second arc-shaped plates are arranged on the vertical edge of the cover plate, and the included angle between the axis of each second arc-shaped plate and the vertical edge is alpha; one side of the cover plate is hinged to the cover surrounding sill on the same side through the hinge assembly; the other side of the cover plate is buckled to the cover surrounding sill through the toggle clip assembly; the cover surrounding sill is watertightly welded at the opening of the deck or the bulkhead structure; a plurality of first arc-shaped plates are arranged on the vertical frame of the covering fence sill, and the included angle between the axis of each first arc-shaped plate and the plane where the vertical frame is located is 180-alpha degrees; the first arc-shaped plate and the corresponding second arc-shaped plate are combined to form a sleeve; and a cable is arranged in each sleeve. By means of the designed hatch cover, after the cable penetrates through the hatch cover, the interior and the exterior of the hatch cover can still be watertight after the hatch cover is closed, and rainwater and the like are prevented from entering the ship.
本发明提供一种水密舱盖,包括:盖板、盖围槛、铰接组件和夹扣组件;盖板的竖边沿设有多个第二弧形板,且每一第二弧形板的轴线与竖边沿的夹角为α;盖板的一侧通过铰接组件铰接于同侧的盖围槛;盖板的另一侧通过夹扣组件扣合于盖围槛;盖围槛水密焊接于甲板或舱壁结构开口处;盖围槛的竖边框设有多个第一弧形板,每个第一弧形板的轴线与竖边框所在面夹角呈180°‑α;第一弧形板和相应的第二弧形板合并形成套管;每一个套管内设电缆线。本发明通过设计的舱盖实现了电缆线串过舱盖后,关闭舱盖仍然能使舱室内外水密,避免雨水等进入船内。
