Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically a sewage drainage pipe. Background Technology

[0002] Drainage pipes play an important role in daily life. Drinking water, sewage, and rainwater are all supplied or discharged through drainage pipes. Compared with cast iron drainage pipes, which are not corrosion resistant, and stainless steel drainage pipes, which are expensive and difficult to transport, plastic drainage pipes have the advantages of low cost, convenient transportation, and stable performance. They are increasingly used in the drainage pipe field, and PVC drainage pipes are currently widely used.

[0003] A PVC drain pipe with a sewage discharge component, disclosed in publication number CN219712724U, includes an L-shaped PVC drain pipe with a through hole on the lower surface of the pipe. An external threaded sleeve is fixedly installed on the top of the through hole. An anti-slip ring on the surface of the sealing cap facilitates the unscrewing of the sealing cap, allowing for regular cleaning of debris inside the PVC drain pipe. When cleaning debris from inside the PVC drain pipe, the filter screen and L-shaped filter plate below the sealing cap are removed from the inside of the L-shaped PVC drain pipe. A scraper is then pressed to scrape away dirt from the surface of the filter screen, which falls onto the surface of the L-shaped filter plate. Finally, the dirt scraped from the surface of the L-shaped filter plate is poured out for cleaning, thus achieving the purpose of cleaning the pipe and preventing blockage. This also facilitates the cleaning of debris inside the pipe.

[0004] While existing technologies can intercept waste, the use of components such as sealing caps, filters, and scraping assemblies makes pipe assembly extremely complex. Therefore, we propose a sewage and drainage pipe. Utility Model Content
