Description

Technical Field

[0001] This utility model relates to the field of road traffic equipment technology, and in particular to a warning rack. Background Technology

[0002] Traditional manhole covers pose three major safety hazards: they are easily pushed open by accumulated water during heavy rain, forming "man-eating traps".

[0003] During heavy rain, surface runoff rapidly flows into drainage pipes through manholes, creating high-speed water flows. According to the fluid mechanics formula P=ρgh (where P is pressure, ρ is water density, g is acceleration due to gravity, and h is water depth), when the water depth at the manhole opening reaches 0.5 meters, the static pressure on the manhole cover can reach 4.9 kPa (approximately 500 kg / m²). If the water flow velocity exceeds 2 m / s, the dynamic pressure will further increase, and the total pressure may exceed the friction between the manhole cover and the base, causing the manhole cover to be pushed open. Therefore, when a manhole cover is pushed open, a flood prevention safety warning device needs to be installed next to it. Utility Model Content
