[0002] Nowadays, various domestic garbage may float on some rivers. Some randomly discarded plastic bottles and plastic bags may float on the water and cause water pollution. The current treatment of river sewage mostly involves salvaging some floating objects. If the salvage is not timely, the pollutants may flow with the water, causing more widespread pollution.

When salvaging pollutants, the movable mechanism forces the movable intercepting net to enter the water trough to intercept the pollutants upstream of the salvaging mechanism. After the salvaging mechanism is put back into the water, the movable mechanism forces the movable intercepting net to enter the placement trough, so that the pollutants can flow into the salvaging mechanism, thereby reducing the possibility of pollutants remaining in the water.

Compared with the second embodiment, the detailed structure of the blocking component is recorded in this embodiment. The blocking component includes a movable mesh plate 17, a support shaft 18, a pulley 19 and a cable 20. A protruding groove is provided on the side wall of the sewage trough 3, and guide grooves are provided on the two side walls of the groove for slidingly connecting the movable mesh plate 17.
