Floating object intercepting and collecting device

The utility model discloses a floating object intercepting and collecting device in the technical field of garbage disposal, which comprises a positioning cross rod, positioning ropes, floating plates and a collecting net, impellers are arranged at the bottoms of the floating plates, floating bulges on the tops of the floating plates are above the water surface, the plurality of floating plates are uniformly locked on the positioning cross rod through the positioning ropes, and the collecting net is arranged on the positioning cross rod. 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 collected
