The invention discloses a damping pump seat used for a solar drainage pump. The damping pump seat comprises a damping seat shell and an inner cavity. The damping shell is provided with water pipe through openings, connecting blocks, threaded holes, tightening screws and a rotating shaft. The two water pipe through openings are arranged, wherein one of the water pipe through openings is in perpendicular contact with the upper wall of the damping shell, and the other one of the water pipe through openings is in contact with the inclined wall of the right side of the damping shell. The four connecting blocks are arranged and are in perpendicular contact with the right wall of the damping shell, and the four connecting blocks are distributed on the two half right sides of the damping shell in a pairwise manner. The four threaded holes are arranged and are in perpendicular contact with the center positions of the connecting blocks correspondingly. The water pipe through openings of the damping pump seat are used for connecting external water pipes to drainage pipe openings of the drainage pump. Each tightening screw is used for locking the corresponding two connecting blocks, and the damping seat shell can be conveniently closed. The rotating shaft is used for opening the damping seat shell, and the drainage pump can be conveniently installed in the damping seat. Telescopic fixing rods are used for stabilizing first springs so that the first springs cannot skew leftwards or rightwards, and sponge plates and the first springs are used for buffering the vertical vibration when the drainage pump works.
