Personnel falling prevention device for flood discharge pipeline

Abstract

The invention provides a personnel falling prevention device for a flood discharge pipeline. The personnel falling prevention device for the flood discharge pipeline comprises a sewer line and a manhole cover, wherein the manhole cover is arranged at the top of the sewer line; a groove, a trigger mechanism and a sewage discharge pipe are arranged in the sewer line; the trigger mechanism is positioned between the groove and the sewer line and is installed on the inside of the wall of the sewer line; the sewage discharge pipe is positioned below the groove; the trigger mechanism comprises a movable plate, a pry bar, a baffle A, a baffle B, a rotating shaft and a spring; the baffle A is positioned in the groove; the baffle B is arranged on the sewer line; the spring is positioned below the movable plate, the pry bar and the rotating shaft and is installed on a wall body of the sewer line; the pry bar and the rotating shaft are located on the same circle center. According to the personnelfalling prevention device for the flood discharge pipeline, the safety of people or other articles can be effectively protected, people are prevented from being washed into sewers, and normal drainageand sewage discharge work further can be carried out.

Description

technical field [0001] The invention belongs to the technical field of sewage pipe rescue devices, and in particular relates to a device for preventing people from falling in flood discharge pipes. Background technique [0002] Drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting and discharging sewage, waste water and rainwater. Including main pipes, branch pipes and pipelines leading to treatment plants, no matter they are built on streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipelines. [0003] The notification number is CN2672172Y, a kind of dual-purpose underground water well, including water pump, well pipe, valve, three-way filter, filter screen, pool. The water pump is installed on the upper end of the well pipe. The three-way filter is installed on the well pipe at an angle of seventy-five degrees. The lower end of the three-way filter is equipped...

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
