A kind of anti-falling object device for municipal sewage pipeline

Abstract

The invention provides an object-falling prevention device for a municipal sewage discharging pipeline. The object-falling prevention device comprises a sewer pipeline and a well lid, and the well lidis mounted at the top of the sewer pipeline; the sewer pipeline is internally provided with a groove, a blocking mechanism and a sewage discharging pipe; the blocking mechanism is located between thegroove and the sewer pipeline and mounted at the junction of the groove bottom and the sewer pipeline through rotating pins; and the sewage discharging pipe is located on the lower part of the groove. According to the object-falling prevention device for the municipal sewage discharging pipeline, impact to baffles due to falling of a water flow in the sewer pipeline is fully utilized to trigger the object-falling prevention device to protect people or other objects, garbage sewage on the baffles can be cleared through a clearing mechanism, the safety of people or the other objects can be effectively protected in stormy weather, people or the other objects cannot be flushed into the sewer pipeline, normal drainage and sewage discharging work can be further conducted, an alertor is furtherarranged in the pipeline, thus people can call for help towards the outside in time advantageously under the situation that the danger occurs, and the survival probability is increased.

Description

technical field [0001] The invention belongs to the technical field of rescue devices for sewage pipes, and in particular relates to an anti-falling object device for municipal sewage pipes. Background technique [0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes", and are usually called municipal drainage pipes in engineering. According to the current situation of the facilities under the municipal roads in China, different pipelines are generally installed, such as electricity, communication, gas, water supply, drainage pipelines and so on. As for the drainage pipes, due to the consideration of rain and sewage diversion measures, that is, the rainwater is generally discharged into the river nearby, and the sewage is discharged into the sewage treatment plant, so the municipal drainage pipes include two kinds of pipes, rainwater and sewage. [0003] The notification number is CN202273314U, a kind of ra...

Problems solved by technology

However, when the manhole cover has been in disrepair for a long time or the manhole cover is lost, the drainage well is exposed. In the case of heavy rain and water accumulation, people or other objects are easily washed into the drainage well by the accumulated water, which is very prone to danger and lacks self-rescue measures. And once a person is washed into a drainage well, the probability of survival is very low
