Multi-preventing well cover

Abstract

The invention discloses a multi-preventing well cover, which comprises a ring support (1) and a cover plate (2) which are rotatably connected together; the internal edge of a cover plate supporting platform (3) is provided with a buckle (6), and a bolt (8) is arranged below the cover plate (2). The bolt (8) slides into the lower part of the buckle (6) when the cover plate (2) is furiously closed and the ring support (1) and the cover plate (2) are caused to be locked together, thus not only effectively preventing the well cover from stealing, but also being capable of preventing the cover plate from bouncing. The cover plate supporting platform (3) is provided with an elastic pad piece which can prevent sound and rupture caused by the collision between the cover plate (2) and the ring support (1) due to applied external forces. Convex patterns on the surface of the cover plate (2) have skid resistance function. The well cover has multiple effects such as theft preventing, sound preventing, bouncing preventing, moving preventing, dislocation preventing, drop preventing, skid preventing and the like.

Description

technical field [0001] The invention relates to a municipal infrastructure article, in particular to a well cover used for inspection wells. Background technique [0002] The wellheads of various inspection wells on the ground need to be covered with manhole covers. The traditional wellhead covering method is to cover the manhole cover directly on the well ring, so the phenomenon of manhole cover loss often occurs, and the rolling of the wheels will cause the displacement and bounce of the manhole cover, and even cause the manhole cover to fly away from the well ring or fall into the well. These factors will cause The lack of wellhead covers seriously affects the safety of pedestrians and vehicles. Manhole covers and well rings are usually made of cast iron. Under the action of wheel rolling or other dynamic loads, the manhole covers and well rings collide, which not only produces noise, but also causes the manhole cover or well rings to break.

AI Technical Summary

Problems solved by technology

Since the cover plate and the ring seat are only in simple contact and have no connection relationship except where the connecting rod or hinge is set, it is easy to open the cover plate and use certain tools to destroy the connecting rod or hinge. Manhole cover loss phenomenon; under the action of wheel rolling or other dynamic loads, the cover plate will still rotate and bounce along the connecting rod or hinge, which not only produces noise, but also the repeated collision between the cover plate and the ring seat will cause the cover plate or The ring seat is broken, which reduces the safety of the manhole cover
