The invention relates to the field of pump station engineering, and in particular relates to a vortex-eliminating structure for a suction sump of a pump station. The vortex-eliminating structure for the suction sump of the pump station comprises a vortex-eliminating plate and a horn-shaped pipe, wherein a water pump water inlet pipe is connected to the top end of the horn-shaped pipe, a water inlet is formed in the bottom end of the horn-shaped pipe, the vortex-eliminating plate is horizontally arranged below the bottom end of the horn-shaped pipe, the cross section of the vortex-eliminating plate is X-shaped, and the vortex-eliminating plate is used for eliminating vortexes near the horn-shaped pipe. With the vortex-eliminating structure for the suction sump of the pump station, the vortex strips near the horn-shaped pipe can be effectively eliminated, so that the uniformity of the water flow entering a pump can be improved, and further, the operating efficiency and stability of the water pump can be improved.
