Abstract
This application discloses a manhole sealing plate for a sewage tank, characterized in that it includes: a sealing plate for sealing the manhole of the sewage tank; an annular sealing gasket at the bottom of the sealing plate; a slot in the sealing plate; and a sampling cover plate rotatably mounted on the slot. By installing the sampling cover plate on the sealing plate, it is convenient for staff to sample and observe the sewage in the tank, avoiding the need to open the entire sealing plate, reducing safety hazards, and ensuring personnel safety. The sealing gasket, combined with subsequent sealing measures, effectively prevents the leakage of sewage odors, improving the environmental quality around the sewage treatment plant. The reasonable setting of the reinforcing ribs and high-quality welding process ensure that the sealing plate will not shift during use and has good strength and deformation resistance, extending its service life.
