Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of manhole covers, in particular to an anti-falling manhole cover. Background Art
[0002] In urban infrastructure, manhole covers are one of the most common facilities, used to cover the manholes of sewers, electricity, communications and other equipment. However, due to the aging, damage or theft of the manhole covers, pedestrians or vehicles may fall into the wells, causing serious safety accidents. For safety reasons, anti-fall devices are generally installed on the manhole covers, but the existing anti-fall manhole covers have certain inconveniences when used.
[0003] A manhole cover structure with an anti-falling function is disclosed in the Chinese utility model patent application No.: CN201821415922.9. After the manhole cover of this structure is installed on the manhole cover seat, the L-shaped clamping block and the manhole cover are clamped on the manhole cover seat by rotating the manhole cover to prevent the manhole cover from being pushed open or easily taken away, thereby improving safety. However, the anti-falling manhole cover structure has a general pressure resistance during use and is easily damaged by pressure after long-term use. Moreover, the anti-falling manhole cover structure cannot give an alarm in time when a fall occurs, and cannot notify workers in time to inspect the manhole cover. For this reason, we propose an anti-falling manhole cover. Utility Model Content
