Problems solved by technology

The invention is mainly used to solve the problem that most of the existing municipal manhole covers directly cover the well circle. When vehicles and pedestrians pass over the manhole cover, the manhole cover will vibrate, causing the well cover and the well circle to collide with each other. Frequent noise will affect the auditory system of

Abstract

The invention belongs to the technical field of well lids, and particularly relates to a municipal anti-noise well lid assembly which comprises a base and a cover plate. The cover plate and the base are connected together through the locking structure, then the hoistway is isolated from the external space, when a vehicle or a pedestrian passes through the upper portion of the cover plate, the cover plate drives the first protruding structure to move downwards, then the first protruding structure extrudes the elastic piece, then the elastic piece generates elastic force, the cover plate is prevented from moving downwards, so the cover plate and the base are prevented from colliding with each other, the damage probability of the cover plate is reduced, the service life of the cover plate is prolonged, noise caused by collision of the cover plate and the base is avoided, noise is reduced, and harm of noise to residents or pedestrians is reduced. Meanwhile, the locking mechanism limits the vertical displacement of the cover plate, so that the vibration amplitude of the cover plate is reduced, the damage of the cover plate to the vehicle and the pedestrian is reduced, and the safety of the vehicle and the pedestrian is protected.

Description

technical field [0001] The invention belongs to the technical field of manhole covers, in particular to a municipal anti-noise manhole cover assembly. Background technique [0002] At present, there are many underground pipeline systems in cities, including water supply and drainage pipelines, power transmission pipelines, and sewage pipelines. , pedestrians or other objects fall into the well, so as to ensure the safety of vehicles, pedestrians or other objects falling. According to the material, manhole covers can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, cast iron manhole covers, etc., which can be used in roads, Sidewalks, squares, lawns and other places. [0003] Most of the existing municipal manhole covers directly cover the well circle. When vehicles and pedestrians pass over the manhole cover, the manhole cover will vibrate, causing the manhole cover and the well circle to collide with each other...
