The invention discloses an optimization structure of a B-shaped manhole cover installation mode. A hinge connecting rod is added at the position of a cover plate, and a hinge base is added on a ship cabin plate, so that the cover plate and the ship cabin plate are connected through a hinge structure; in this way, after a manhole cover is disassembled, the manhole cover is suspended to the hinge base; in addition, a pin control is matched with the hinge connecting rod, and a plug pin is used for fixing the cover plate when the manhole cover is opened; it is ensured that the manhole cover will not swing along with swinging of a ship when opened. Accordingly, the manhole cover is convenient to disassemble and assemble, and more energy is saved for a worker to ensure the personal safety in the disassembling process.
