Abstract

The utility model provides a waterproof manhole cover, it is " ] by waterproof cover and cross section " type annular seal circle constitutes, waterproof capping big -end -up, the lateral wall slope, to seal up the snare when implement connecting on the edge of well lid, then in filling in well seat mouth with waterproof manhole cover, the gravity that relies on the waterproof cover with sealing washer side extrusion between the lateral wall that waterproof cover and well seat slope to play waterproof effect.

Description

Waterproof well cover

Technical field

The utility model relates to a kind of well lid, and particularly a kind of rainwater that can prevent enters well lid in cable work well by well head.

Background technology

Cable well lid is in the market most of non-watertight, and when raining, rainwater can flow in active well along the gap between well lid and well seat wall.Once ponding in active well, can the cable in active well, equipment etc. be immersed in water, bring hidden danger to the operation of electric power, also make troubles to maintenance work simultaneously.Market exists the water proof type well lid of other types, but need bolt to coordinate press seal circle to reach the object of waterproof, bolt revolves bad meeting and causes poor sealing to cause well lid to leak, and installs trouble.The utility model patent, adopt sealing ring and the sealing means of special construction, non-bolt designs, and has simplified installation procedure.

Summary of the invention

In order to improve the sealing reliability of Waterproof well cover, simplify installation procedure, the utility model provides the different sealing ring of a kind of special type simultaneously, and it coordinates with Waterproof well cover and reaches waterproof object, adopts non-bolt design simultaneously, has simplified installation procedure, save the set-up time.

The utility model solves the technical scheme that its technical problem adopts: Waterproof well cover is "] by waterproof cover and cross section " type annular seal ring forms; There is the waterproof cover of sealing ring to fill in well seat mouth in cover when implementing to connect, rely on the gravity of waterproof cover to be squeezed in by sealing ring between the sidewall of waterproof cover and well seat, thus reach waterproof object; Waterproof cover is up big and down small, sidewall slope; Waterproof cover can be circular, square and oval; Well seat, with holder shoulder, prevents waterproof cover from surprisingly falling into when mounted in active well.

The beneficial effects of the utility model are, have both prevented well lid percolating water, eliminate again bolt and fix, and have simplified installation procedure.
