Problems solved by technology

[0003] At present, there are some manhole covers on the market that can be relatively quiet, but it is still unavoidable that when vehicles pass by the manhole cover, the manhole cover will vibrate, resulting in a short service life of the manhole cover, and the annual maintenance cost of the well remains high.

Abstract

The invention discloses an anti-noise well lid. The anti-noise well lid comprises a well body. A well lid body is arranged at a well mouth of the well body. An energy absorption device is arranged in the well body and located below the well lid. An elastic layer is arranged between the well lid body and the energy absorption device. The energy absorption device is fixed to the well wall of the well body. The energy absorption device is provided with a pressure sensor and a signal transmitter. The pressure sensor is connected with a monitoring system of a well lid management department through the signal transmitter. Through the structure, it can be seen that the well lid body of the anti-noise well lid is connected with the well wall through a rubber layer and an annular energy absorption box, so that it is avoided that the anti-noise well lid generates noise when a vehicle passes the anti-noise well lid. Besides, the rubber layer has a certain buffering function, achieves the protection function on the well lid body and the well body and prolongs the service lives of the well body and the well lid body.

Description

technical field [0001] The invention relates to the field of an anti-noise well cover, in particular to an anti-noise well cover. Background technique [0002] The manhole covers of these various pipeline units are arranged on the streets and alleys of the city. Noise will be generated when vehicles pass by, which not only disturbs the people, but also the sound is generated by vibration. will cause damage. When the well cover is damaged, the cost of replacement or maintenance is high, and if the well body is also damaged, the maintenance cost for the well body is even higher. [0003] At present, there are some manhole covers on the market that can be relatively quiet, but it is still unavoidable that when vehicles pass by the manhole cover, the manhole cover will vibrate, resulting in a short service life of the manhole cover, and the annual maintenance cost of the well remains high. Contents of the invention [0004] The purpose of the present invention is to overcome...
