AI Technical Summary
Technical Problem
Existing drainage well covers are prone to plastic debris intrusion, leading to blockage risks, and the filter screens of well covers with filtration structures are easily broken.
Method used
The filter uses a metal wire mesh, which is fixed by a fitting groove. Combined with a support screw and lifting plate structure, it reduces contact at the fixed end and increases stability. The design of connecting rods and side arc rods suspends plastic foreign objects to reduce clogging.
Benefits of technology
It extends the service life of the filter wire mesh, reduces the risk of corrosion and breakage, effectively prevents plastic foreign objects from clogging the filter, and maintains filtration stability.

Abstract
This utility model relates to the field of drainage manhole cover technology, specifically to a municipal road drainage manhole cover, including a manhole cover body, side positioning ring plates, and supporting screws. Side limiting plates are provided at both ends of the outer side of the manhole cover body, and shock-absorbing blocks are arranged at the bottom of the side limiting plates. A side positioning ring plate is mounted at the bottom of the side limiting plates, and an interlocking groove is opened on the inner side of the top of the side positioning ring plate. The interlocking groove and the outer ring of the side limiting plate are mutually engaged. A road base is mounted on the outer side of the side positioning ring plate. An inner flared groove is opened at the center of the bottom of the manhole cover body, and a side opening groove is obliquely opened on the outer side of the inner flared groove. This utility model solves the problem that in the prior art, existing drainage manhole covers are prone to plastic foreign objects intruding into the drainage pipe during installation and use. These plastic foreign objects are difficult to decompose, posing a significant risk of blockage to the drainage pipe. Furthermore, drainage manhole covers with filter structures are prone to filter screen breakage under continuous pressure.
