Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a municipal manhole cover. Background Art

[0002] Manhole covers are used to cover deep wells on roads or in homes to prevent people or objects from falling. They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Its main uses include protecting municipal pipelines (such as drainage pipes, water pipes, gas pipelines, etc.), cables, optical cables and other facilities to prevent these facilities from being affected by the external environment, such as rainwater, sewage, dust, corrosion, etc., thereby ensuring their stable operation.

[0003] When most of the manhole covers currently in use are designed and manufactured, the size of the drainage holes on the manhole covers is carefully designed and calculated to ensure effective drainage during normal rainwater discharge. However, in extreme rainy weather, the amount of rainwater does increase dramatically. At this time, relying solely on the fixed drainage holes on the manhole cover may not be able to meet the drainage needs. If the manhole cover is opened, there is a risk of the manhole cover being washed away or pedestrians falling. For this reason, a municipal manhole cover is proposed. Utility Model Content

The top end of one side of the plurality of side panels 41 is provided with an inclined surface. While blocking the drainage hole 34, the inclined surface at one end allows a gap to exist between the drainage hole 34 and the cover body 31 for normal drainage. The plurality of side panels 41 respectively correspond to the positions of the plurality of drainage holes 34.

[0037] Preferably, a rotating column 42 is fixedly connected to the top of the turntable, and the top of the rotating column 42 movably passes through the surface of the mounting groove 32 and is placed in the inner cavity of the groove 33.
