Abstract

An anti-theft safe water-draining inspection-well cover comprises a cover plate (1) and a cover base (2), wherein the shank (3) of the cover plate (1) is hinged to the groove (4) of the cover base (2). The anti-theft safe water-draining inspection-well cover is characterized in that a security protection device (5) is arranged on one side of the cover plate (1), which is opposite to the side, on which the shank (3) is arranged, of the cover plate (1); the security protection device (5) comprises a protective hook (6) and an elastic element; a hook part (7) is arranged at the lower end, facing the edge of an inspection well mouth in the cover base (2), of the protective hook (6) and provided with a hooking acting surface (8) matched with the lower surface of the edge of the inspection well mouth in the cover base (2). When hydraulic pressure in the inspection well is too high and jacks up the cover plate of the inspection well cover, the protective hook of the security protection device (5) immediately takes effect to enable the cover plate (2) of the inspection well cover to be maximumly and slightly opened by 15 to 20 degrees, so that the safety of the inspection well cover is improved.

Description

technical field [0001] The invention specifically relates to an inspection shaft cover. The manhole cover is especially suitable for the manhole cover of the drain well of the municipal drainage pipeline. Background technique [0002] As the urban infrastructure, the falling wells of municipal drainage pipes and the inspection wells of communication, power supply and water supply pipelines are installed in large numbers in motor vehicle lanes, non-motor vehicle lanes, sidewalks, residential areas and green belts. For these falling wells and inspection wells all need to be equipped with inspection well covers. [0003] At present, the most common inspection well cover is cast iron inspection well cover, which is composed of a cover plate and a cover base. The cover base is buried in the ground, and the cover plate covers the cover base. The cover plate and the cover base are split structures . This cast iron manhole cover has high strength and long service life, but becaus...
