The municipal manhole cover plate opening structure comprises a mounting base and a sealing mechanism, a mounting groove is formed in the upper end face of the mounting base, a manhole cover plate body is arranged in the mounting groove, and a cavity is formed in the manhole cover plate body. According to the device, through cooperative arrangement of a rotary disc, a rotating rod, a first gear and a second gear, a threaded rod can be driven to rotate, the threaded rod drives a first inclined block to move upwards through a threaded sleeve and a transverse plate, the first inclined block can push two second inclined blocks to move oppositely, and the second inclined blocks can drive plug pins to be inserted into clamping grooves through sliding plates; the manhole cover plate body is limited and fixed, the anti-theft performance of the manhole cover plate can be improved through matched arrangement of the irregular fluted disc and the tooth groove, the manhole cover plate body is prevented from being stolen and moved, cables and optical cables in an inspection well are prevented from being damaged due to the fact that no shielding object exists on the inspection well opening, and therefore the service life of the optical cables is prolonged, and the safety risk is reduced; pedestrians and vehicles can pass conveniently.
