Drainage pipe network flow measuring device and method

Abstract

The invention discloses a drainage pipe network flow measuring device. The drainage pipe network flow measuring device comprises a host and a sensing probe, the sensing probe comprises a shell, a gyroscope arranged in the shell, a flow velocity measuring probe arranged at the bottom of the shell, a plurality of laser distance measuring probes arranged on the shell, and a rudder arranged at the tail end of the bottom of the shell, the laser distance measuring probes are circumferentially and uniformly arranged on the shell, the detection directions of the laser distance measuring probes are distributed on the same cross section of the shell at equal angles, and the laser distance measuring probes reversely intersect at the center of the cross section of the shell. The invention further discloses a drainage pipe network flow measuring method, and the pipe network diameter, the pipe wall track, the water level and the pipe network flow can be measured; and the pipeline diameter and the cross section area can be measured under the condition that personnel do not go into a well.

Description

Technical field [0001] The present invention belongs to the technical field hydrological monitoring apparatus, in particular A screen drain flow rate measuring device, further relates to a process for flow measurement drainage network. Background technique [0002] With the relationship between human urbanization municipal pipe network with people's lives become increasingly close. Distribution network traffic monitoring can detect snuck sewage waste-water treatment, sewage infiltration and seepage and other issues, while monitoring the flow of data can provide supporting data to reduce the probability of occurrence of waterlogging city pipe network construction and maintenance, improve sewage collection efficiency, improve people's Quality of Life. [0003] Currently municipal sewer manholes are used to install network traffic monitoring equipment, since the shape of the manhole damage to the pipe network present turbulence phenomena, the water level in the tube, the flow rate, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the municipal drainage pipe network uses inspection wells to install flow monitoring equipment. Due to the damage of inspection wells, the shape of the pipe network has turbulent flow, and the water level, flow velocity, and flow direction in the pipe are all deviated, resulting in measurement errors, and even completely wrong data.
