The invention belongs to the technical field of manhole covers, and particularly relates to a rust-proof manhole cover. The device comprises a base plate, an anti-rust cover, a first sealing cover and a second sealing cover, and an inlet and an outlet are formed in the base plate; the anti-rust cover covers the inlet and outlet in a matched mode, auxiliary blocks are fixed to the two sides of the anti-rust cover respectively, the auxiliary block on the first side of the anti-rust cover is rotationally connected to the base plate through a penetrating rotating shaft, and the auxiliary block on the second side of the anti-rust cover is connected with a first threaded hole formed in the base plate through a penetrating bolt. The first sealing cover covers the rotating shaft on the first side of the rust-proof cover; and the second sealing cover covers the bolt on the second side of the rust-proof cover. The manhole cover is used for solving the problem that a bolt and a rotating shaft on the manhole cover are easily rusted by seawater. And the first sealing cover and the second sealing cover are used for sealing components on the manhole cover, so that the overall corrosion resistance of the manhole cover is improved.
