The utility model relates to a linkage pollution cleaning type trash rack structure which comprises a trash rack arranged in front of a hydropower station water inlet. The trash rack is arranged obliquely. The lower end of the trash rack is hinged to an underwater base. An impurity collecting frame and a stand column arranged on the water-meeting side of the trash rack are further included. A rotating disc is arranged at the upper end of the stand column. The rotating disc is connected with a first pulling rope connected with the trash rack and a second pulling rack connected with the impurity collecting frame. The rotating disc is provided with two connecting discs with different diameters in the axial direction. The two connecting discs are connected with the first pulling rope and the second pulling rope respectively. When the rotating disc carries out rotating collecting and the trash rack rotates to the vertical position, the impurity collecting frame is placed above the water level. The trash rack and the impurity collecting frame are subjected to linkage, clearing of impurity intercepting on water and below water is achieved conveniently and quickly, labor intensity is lowered, efficiency is improved, and the linkage pollution cleaning type trash rack structure is simple and low in cost.
