Floating cover / product

Floating cover
Floating cover

Nowadays, the problem of city drainage goes badly, which has brought some badly hydrocephalus problems, just like what happened in Beijing this summer. However, those heavy manhole cover didn’t work very well, because of the small drainage area. So I designed a new cover, which is made of a kind of plastic that can float in water and bears the force. When water overflows the cover, under the action of the buoyancy, the cover floats up in order to expand the area of drainage. For the safety of people and cars, some ropes are used to limit the max floating height of the cover. Water disappeared, the cover goes back.
