AI Technical Summary

Technical Problem

Existing manhole covers can easily cause safety hazards during emergency drainage and are difficult to operate, especially when a vehicle hits the cover, which may cause a serious accident.

Method used

A safety manhole cover was designed, comprising a first manhole base, a second manhole base, a rotating base, a transmission assembly, and a cover plate. The cover plate is flipped through the transmission assembly and a bevel gear structure, allowing rainwater to flow into the drainage pipe through a channel. This prevents the cover plate from being higher than the upper surface of the manhole base, reducing the difficulty of operation.

Benefits of technology

This approach simplifies emergency drainage operations, reduces the difficulty of flipping manhole covers, and avoids safety risks caused by the cover plate being higher than the upper surface of the manhole base, all without increasing safety hazards.
