Vented precipitation guarding manhole cover assemblies
Vented precipitation guarding manhole cover assemblies include a manhole cover having a manhole cover protrusion. The manhole cover protrusion has a protrusion edge, a protrusion surface contiguous with and extending from the protrusion edge and a protrusion apex contiguous with the protrusion surface. A manhole cover vent opening extends through the manhole cover protrusion and the manhole cover.
Vented precipitation guarding manhole cover assembly
A vented precipitation guarding manhole cover assembly, comprising: a manhole cover having a top exterior surface and a bottom interior surface; a vent opening extending through the manhole cover between the top and bottom surfaces; a valve assembly in fluid communication with the vent opening and extending from the bottom interior surface, the valve assembly configured to extend from the bottom interior surface at least partially inside the manhole, the valve assembly operable between an open position, to enable gas to exit from the manhole, and a closed position, to prevent the flow of fluid from the top exterior surface into the manhole.
COVER
A cover for a utility enclosure includes a cover having a top, a bottom, a front side, a rear side, a left side, and a right side, defining an interior. The cover further includes a plurality of ribs in the interior dividing the interior into a plurality of spaces. The cover further includes the top having one or more air vents. The cover further includes the air vents having channels constructed to vent air in the spaces to an exterior of the cover, thereby preventing flotation of the cover in water.
Vented precipitation guarding manhole cover assembly
A valve assembly for use with and extending from an underside of a vented manhole cover assembly. The valve assembly is operable between an open position, to enable gas to exit from the manhole, and a closed position, to prevent the flow of the fluid into the manhole. The valve assembly includes a valve body having a first opening and a second opening and a fluid passage extending between the first and second openings. The valve assembly further includes a drain hole extending through the valve body configured to allow fluid drain therethrough. The valve assembly also includes a valve member moveable between the open position and the closed position, such that in response to the fluid entering through the first opening, the valve member moves from the open position to the closed position to prevent the flow of the fluid into the manhole, and wherein in response to fluid draining through the drain hole, the valve member moves from the closed position to the open position.

Sel-reporting monitor for integrity and conditions of manhole cover
A monitor for monitoring the conditions of and around and under a manhole cover senses current conditions of the manhole cover and enables wireless self-reporting of such conditions at intervals and upon certain emergency situations arising. The monitor of the manhole cover includes a shell, a cover plate, and a base. The cover plate is detachably assembled with the shell. The base connects the shell with the manhole cover. The base includes a magnet to which the manhole cover is strongly attracted. The monitor is held to the manhole cover by the magnet. A mounting operation of the monitor requires only placement by hand.
