Acoustic testing scheme for drainage outlet

Most of the drainage outlets in various regions are located in rivers and embankments, with turbid water and complex terrain, making it difficult to use conventional methods for drainage, especially for illegally discharged sewage pipes, which are even more concealed and difficult to investigate. By adopting the latest acoustic detection technology, we can effectively monitor the real-time situation underwater. Combined with water quality sensors, water collectors, water cameras, Beidou positioning system, 5G network, unmanned ship technology, we can achieve full functions such as real-time investigation, evidence collection, and solidification of evidence in the central command hall. Thus achieving efficient office, efficient disposal, efficient law enforcement, and providing the public with a beautiful environment of green mountains and clear waters.

Utilize underwater acoustic imaging sonar installed on the ship's hull to observe the underwater conditions of the riverbank in real-time. Record continuous sonar images on the industrial computer, including the current time and satellite positioning coordinates, to facilitate subsequent inspections. At the same time, according to user requirements, underwater water quality parameter sensors can be installed, such as oxygen content sensors, methane sensors, turbidity sensors, salinity sensors, etc., and real-time water quality parameters at the current location and time can be recorded. Install high-definition cameras at suitable positions on the ship deck, adjust the shooting angle to sonar scanning above the water body, synchronously capture images above the water surface, and record them on a hard disk recorder.

Using 5G/4G network modules, real-time transmission of sonar data, video materials, and water quality parameters to the central control room facilitates centralized management. During subsequent review, sonar data, location coordinates, video footage, and water quality indicators can be replayed based on the timeline to form a comprehensive investigation data chain.
