Comprising a sewage discharge ditch, a main filter screen, a garbage temporary storage pool, a folding plate mechanism, an opening and closing plate mechanism, an auxiliary filter screen and the like. Sewage is continuously discharged in the sewage discharging ditch, the garbage is intercepted through the obliquely arranged main filter screen, and due to the arrangement of the folding plate mechanism and the obliquely arranged main filter screen, the garbage is accumulated towards the corner of the right side, and the left side is not prone to being blocked. When the device is used for a certain period of time or the main filter screen is blocked, the folding plate mechanism and the opening and closing plate mechanism are started to drive the first channel and the second channel leading to the garbage buffer pool to be opened, the wide plate seals the channel at the front end of the main filter screen, water flow reversely impa
