The operator puts cement, aggregate, additives, etc. into the material cylinder 3 in proportion.

[0021] Furthermore, the mobile mixing assembly includes a support frame 9, a threaded rod 10, a first motor 11, and a mounting base 13. The support frame 9 is fixedly connected to the outer surface of the connecting base 4, and a fixing plate is fixedly connected to the outer surface of the support frame 9. The first motor 11 is fixedly installed on the top of the support frame 9. The threaded rod 10 is rotatably connected between the support frame 9 and the fixing plate. The output end of the first motor 11 is fixedly connected to the threaded rod 10. The mounting base 13 is threadedly fitted onto the outer surface of the threaded rod 10. The first motor 11 drives the threaded rod 10 to rotate. The mounting base 13 is limited by the guide post 16, causing it to move axially along the threaded rod 10, thereby driving the mixing blade 14 to reciprocate up and down inside the material cylinder 3 to achieve three-dimensional mixing.

[0022] Furthermore, a rotating shaft is rotatably connected to the bottom of the mounting base 13, and multiple equidistantly distributed mixing blades 14 are fixedly sleeved on the outer surface of the rotating shaft. The multiple mixing blades 14 are located inside the material cylinder 3. The second motor 12 drives the rotating shaft to rotate, thereby driving multiple sets of mixing blades 14 to perform radial mixing of the concrete.

[0023] Furthermore, two symmetrically distributed guide columns 16 are fixedly connected between the support frame 9 and the fixed plate. The mounting base 13 is movably connected to the two guide columns 16. A second motor 12 is fixedly installed on the top of the mounting base 13. The output end of the second motor 12 is fixedly connected to the rotating shaft. The mounting base 13 is moved axially along the threaded rod 10 by being limited by the guide columns 16.

[0024] Furthermore, a one-way valve 17 is fixedly installed on the outer surface of the material cylinder 3, and a slurry discharge pipe 18 is fixedly connected to the outer surface of the one-way valve 17. A snap-fit ​​block 15 is fixedly connected to the outer surface of the material cylinder 3. The snap-fit ​​block 15 has a through hole inside and is located above the one-way valve 17. The end of the slurry discharge pipe 18 is movably snapped into the snap-fit ​​block 15. The operator puts cement, aggregate, additives, etc. into the material cylinder 3 in proportion.

[0025] Furthermore, the grout discharge pipe 18 is hollow, with a threaded section in the middle and both ends being rigid and non-deformable pipes. The threaded section in the middle of the grout discharge pipe 18 allows for adjustment of the overall length to accommodate different grouting depths. High-strength metal pipes are used at both ends to ensure the stability of the pipe opening during grouting.

[0026] Furthermore, a drive gear 20 and a driven gear 21 are rotatably connected to the bottom inner wall of the base 2. The drive gear 20 and the driven gear 21 are meshed together. A third motor 19 is fixedly installed on the top of the base 2.

The third motor 19 drives the drive gear 20 to rotate, and through gear meshing, drives the driven gear 21 to rotate, thereby driving the connecting seat 4 and the material cylinder 3 to rotate as a whole, thereby driving the scraper 8 to rotate.

[0027] Furthermore, the telescopic scraping assembly includes a connecting column 5, a moving block 6, a first connecting rod 7, a scraper 8, a fixing block 22, a second connecting rod 23, and an adapter frame 24.

Multiple first connecting rods 7 are rotatably connected to both ends of the second connecting rod 23. The multiple first connecting rods 7 are rotatably connected to each other. The adapter frame 24 is fixedly connected to the outer surface of the outermost first connecting rod 7. The scraper 8 is fixedly connected to the bottom of the adapter frame 24. The moving block 6 slides outward along the connecting column 5, pushing the second connecting rod 23 to unfold, thereby driving multiple sets of X-shaped first connecting rods 7 to unfold step by step. Thus, the length can be adjusted to adapt to different spacings, so that the scraper 8 is located at the grouting position.

[0028] Furthermore, the second link 23 and multiple first links 7 are arranged in an X shape, and the adapter 24 is arranged in an L shape, pulling the outermost adapter 24.

[0029] Furthermore, the base 2 is located at the center of the wind turbine foundation body 1, and the entire device is hoisted to the center of the wind turbine foundation body 1 by a hoisting device.

[0030] Working principle: First, the entire device is hoisted to the concentric position of the wind turbine foundation 1 using a hoisting device. Before grouting, the area of ​​the wind turbine foundation 1 to be grouted needs to be cleaned. Pull the outermost adapter frame 24, which in turn drives the moving block 6 to slide outward along the connecting column 5, pushing the second connecting rod 23 to unfold, which in turn drives multiple sets of X-shaped first connecting rods 7 to unfold step by step, thus adjusting the length to adapt to different spacing. When the scraper 8 is in the grouting position, the operator puts cement, aggregate, additives, etc. into the material cylinder 3 in proportion. The clamping block 15 fixes the end of the grout discharge pipe 18, and the one-way valve 17 is in the closed state. The third motor 19 is started, which drives the drive gear 20 to rotate. Through gear meshing, the driven gear 21 is driven to rotate, which in turn drives the connecting seat. 4. The material cylinder 3 rotates as a whole, thereby driving the scraper 8 to rotate. At the same time, the second motor 12 is started. The second motor 12 drives the rotating shaft to rotate, driving multiple sets of mixing blades 14 to radially mix the concrete. The first motor 11 drives the threaded rod 10 to rotate. Through the guide column 16, the mounting seat 13 moves axially along the threaded rod 10, driving the mixing blades 14 to move up and down in the material cylinder 3 to achieve three-dimensional mixing. After the slurry is transported and mixed, the grouting area is also cleaned. Then the third motor 19 is turned off, the one-way valve 17 is opened, and the concrete is discharged through the slurry discharge pipe 18. The slurry discharge pipe 18 has a threaded pipe in the middle section, and the overall length can be adjusted to adapt to different grouting depth requirements. The two ends are made of high-strength metal pipes to ensure the stability of the pipe opening position during grouting.
