Floating object intercepting and collecting device

The invention discloses a floating object intercepting and collecting device in the technical field of garbage treatment.The floating object intercepting and collecting device comprises a positioning cross rod, positioning cables, traction cables, floating plates and a collecting net, impellers are arranged at the bottoms of the floating plates, floating protrusions on the tops of the floating plates are located above the water surface, and the multiple floating plates are evenly locked on the positioning cross rod through the positioning cables; the floating plates can be locked on the positioning transverse rod side by side, so that an upstream river channel of a bridge is intercepted, garbage is effectively collected and treated in a centralized mode, the floating plates can rotate by impacting the impeller through water flow, the rotating floating plates can effectively push the garbage to one side, and therefore the multiple floating plates are sequentially connected, and the garbage can be effectively c
