[0002] Drainage projects are projects that remove human domestic sewage, various wastewater from production, and excess surface water. They are composed of drainage pipes (or ditches), wastewater treatment plants, and final treatment facilities. Water supply projects supply water for life and production to residents and factories, mines, and transportation companies, as well as water for fire fighting and road greening. Water supply and drainage pipes need to filter impurities in the water during operation to avoid clogging inside the pipes. However, most traditional filtering devices are one-piece structures, which are not convenient for cleaning the inner wall, and are prone to clogging over time. In addition, the screen is prone to accumulate a large amount of impurities inside after long-term use. If it is not cleaned for a long time, it will affect the overall water filtering effect of the device.
