The invention provides a device used for large water level amplitude of a reservoir, intercepting dirt and ensuring flood discharge and electricity generation safety. The device comprises a right bankslope, a left bank slope, an anchor cable, an anchor head and a concrete base, wherein the anchor cable and the anchor head are arranged in the right bank slope and the left bank slope, and the concrete base is arranged on the slope feet of the right bank slope and the left bank slope. Stand columns are arranged on the concrete base in a buried manner. The stand columns are connected with the anchor head through transverse connecting rods. A fixed intercepting net is arranged between the stand columns and the right bank slope and the left bank slope. A floating intercepting net is arranged between the stand columns of the right bank slope and the left bank slope. The floating intercepting net connects a sleeve ring with balls and the stand columns through a high-strength steel cable. An upper portion high-strength steel cable and a lower portion high-strength steel cable are arranged on the upper portion and the lower portion of the floating intercepting net correspondingly. The lowerportion high-strength steel cable is provided with a floating ball. The dirt floating on the water surface is intercepted through the floating intercepting net. The device can well adapt to the largewater level amplitude of the reservoir, the dirt can be effectively intercepted, during the flood discharge period, a flood discharge channel can be prevented from being blocked by the dirt, and theharm of dam flooding of flood is avoided.
