As can be seen from the figure, a control valve is provided at the bottom end of the discharge pipe 22. Opening the discharge pipe 22 controls the outflow of material from the feeding box 17. The mud pump 2 can pump the mud from the mud bin 4 into the feed pipe 3, which then feeds the mud into the wind turbine pile foundation scour pit, thereby repairing the scour pit.

[0028] U-shaped frames are fixed on both sides of the support plate 13, and the feeding box 17 is connected to the support plate 13 through the U-shaped frames.

[0029] The interior of the chute 5 is rotatably connected to a screw rod 7 via a bearing, and the slider 6 is screwed onto the screw rod 7 via a thread. A cavity 11 is provided on one side of the hull 1 close to the mud bin 4, and a transmission assembly is provided between the two screw rods 7.
