| titleOfInvention | Whirl warning well lid |
| abstract | The invention discloses a rotational flow warning well lid which comprises a lid body, wherein the lid body comprises a central part, a placing edge and a plurality of rotational flow guide strips connected between the central part and the placing edge, the rotational flow guide strips are annularly arranged around the center of the lid body at intervals, and a water discharge groove is formed between every two adjacent rotational flow guide strips; the upper surface of the rotational flow diversion strip is provided with a gradient which gradually decreases from the placing edge to the central part. Compared with the prior art, the invention has the advantages that by arranging the rotational flow guide strips, when ponding passes through the well cover, vortex can be generated at the water surface, the warning effect is realized for vehicle drivers and pedestrians, and people are prompted to avoid the well cover area. |
