This application relates to the technical field of wastewater testing equipment, and in particular to a device for detecting sewage outlets in river channels. The device includes a fixed ring and a cleaning section. The fixed ring has a bottom ring and a top ring, with the top ring hinged to the top of the bottom ring. A detection box is installed at the bottom of the bottom ring, and a filter groove is formed inside the bottom ring. The filter groove is located at the top of the detection box, and a filter screen is installed inside the filter groove. This invention cleans the filter screen using the cleaning section and an arc-shaped block. Because the arc-shaped block and the outlet block block obstruct the water channel in the remaining area of ​​the fixed ring, wastewater flows into the channel, pushing the bottom push plate to rotate along the shaft. The arc-shaped scraper at the edge cleans impurities on the filter screen, achieving cyclic cleaning of the filter screen. This allows the cleaning section to continuously scrape away contaminants from the filter screen, preventing clogging, ensuring wastewater flow and continuous testing, simplifying the structure and reducing energy consumption, and guaranteeing the accuracy of wastewater testing results.
