The foundation pit dewatering device is characterized in that four turbine blades are fixedly connected to the outer side of a rotating shaft, the two ends of the outer side of the rotating shaft are fixedly connected with top columns, an annular groove is formed in the bottom of the inner side wall of a filter box, and a filter plate is installed in the annular groove; four edges of the filter plate are arranged at the bottom of the annular groove, the fixing frame is fixedly connected to the top of the filter plate, and a through groove is formed in the bottom of the filter box; water flow pushes turbine blades fixed to a rotating shaft to rotate, so that a jacking column is driven to rotate, a first arc-shaped block at one end of the jacking column abuts against a second arc-shaped block at one end of a fixing frame, a filtering plate vibrates in an annular groove by a certain amplitude, and the filtering effect of the filtering plate is improved through repeated vibration of the filtering plate.
