Flow guide inspection well cover
The invention discloses a flow guide inspection well cover which comprises a basic round plate, flow guide holes and protection grain. The flow guide holes and the protection grain are arranged on the basic round plate, the protection grain is evenly arranged on the upper surface of the basic round plate, the flow guide holes penetrate through the upper surface and the lower surface of the basic round plate, a rubber sealing ring is arranged on the outer circle of the basic round plate, a ring of locating groove is formed in the outer circle of the basic round plate, a ring of protruding rib corresponding to the locating groove is arranged in the rubber sealing ring, an inward concave conical face is arranged on the upper surface of the basic round plate, and an outward protruding conical face is arranged on the lower surface of the basic round plate. In this way, according to the flow guide inspection well cover, slip and dirt of the inner wall of an inspection well are reduced, dirty water is concentrated, impacting force is large, so that the blocking problem is reduced, and maintenance is effectively reduced.
