AI Technical Summary
The existing grid-type central drainage system is not convenient for cleaning the garbage in the filter screen holes, and the operation is cumbersome and poses safety hazards.
A structure comprising a first drain pipe and a second drain pipe fixedly connected to each other is designed. It adopts a combination of a perforated plate and a plug rod, combined with a mechanical structure of a sealing plate, an extrusion frame and a threaded rod, to achieve convenient cleaning of the grille.
It achieves efficient cleaning of waste from the bar screen, reduces labor intensity and safety risks, and improves the convenience and reliability of drainage device maintenance.
