Safe Cover by WeiQichong from china
designer's own words:
The manhole without covers often cause accidents. This is a design about manhole covers for security, which contains a cover, a base and a spring coated with a fluorescent layer. At ordinary times, the spring is compressed inside the base by the cover. And it bounces if the cover is lost, indicating a warning to passersby, which works well especially at night due to the fluorescent material.
