Anti-falling manhole

Abstract

An anti-falling manhole comprises a manhole seat, a warning body and a pull rope, wherein the warning body has a warning function and can float on the water surface; one end of the pull rope is connected with the manhole seat, and the other end of the pull rope is connected with the warning body; and the warning body is suspended in the manhole seat in a normal state. The warning body is connected in the manhole seat through the pull rope, accordingly, when the manhole is full of rain water and the rain water spills out of the manhole, the warning body can be exposed above the manhole under the buoyancy action, a warning effect is realized, when a person opens a manhole cover for rapid drainage or the manhole cover is washed away by water, the warning body floating above the manhole seat can be used for warning pedestrians of being away from the manhole timely, and dangers of falling into the manhole due to heavy rainfall are greatly reduced. Therefore, the anti-falling manhole is reasonable in structure and can improve the safety of the pedestrians walking in the water in heavy rain days under the condition that the manhole cover doesn't exist.

Description

technical field [0001] The invention relates to a manhole, in particular to an anti-falling manhole capable of warning pedestrians to avoid falling into the manhole after the manhole cover is lost. Background technique [0002] We know that some manholes are usually set up next to the roads or sidewalks in the city. The function of these manholes is to allow rainwater to flow into the manholes when it rains, and then drain the rainwater through underground pipes connected to the manholes. Go, so that it will not cause water accumulation on the road to cause inconvenience to pedestrians and vehicles. Usually, for the safety of pedestrians, a manhole cover will be put on the top of the manhole, and there are several small holes on the manhole cover, and the rainwater will flow into the manhole through the small holes. When several holes cannot be drained in time, people will open the manhole cover to achieve the purpose of rapid drainage. However, in case of heavy rainfall, e...

Problems solved by technology

Usually, for the safety of pedestrians, a manhole cover will be put on the top of the manhole, and there are several small holes on the manhole cover, and the rainwater will flow into the manhole through the small holes. When several holes cannot be drained in time, people will open the manhole cover to achieve the purpose of rapid drainage. However, in case of heavy rainfall, even after opening the manhole cover, the rainwater cannot be drained in time, so that the rainwater will fill up the manhole. If the manhole overflows, due to the influence of garbage, light, and water flow speed, the position of the manhole cannot be seen, which will cause pedestrians to fall into the manhole, causing life danger
