[0051] In existing technologies, when grinding the inner wall of wind turbine towers, the towers are horizontal, and the grinding equipment is carried into the towers by a trolley. During grinding, the equipment needs to be manually held and aimed at the rusted areas. However, this method of manually grinding the inner wall of wind turbine towers is inefficient and labor-intensive.

[0052] To address the aforementioned problems, this invention provides a rust removal device for wind turbine towers, comprising a moving vehicle, an adjusting component, a rotating component, and a rust removal component. The adjusting component, under the action of a first driving member, adjusts the position of the rotating component, allowing it to abut against the inner wall of the wind turbine tower. Under the action of a second driving member, the rotating component rotates along the circumference of the wind turbine tower, enabling the grinding head to grind the inner wall of the tower along its circumference. The moving vehicle can drive the adjusting component, rotating component, and rust removal component to move axially within the wind turbine tower, allowing the grinding head to grind the inner wall along its axial direction. This eliminates the need for manual hand-held grinding, thereby improving work efficiency and reducing labor intensity.

[0053] The rust removal equipment for wind turbine towers provided in this invention will be described in detail below with reference to specific embodiments.

[0054] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides a rust removal device for wind turbine towers, applied to a wind turbine tower 100, including a moving vehicle 10, an adjusting component 20, a rotating component 30, and a rust removal component 40; the moving vehicle 10 can move inside the wind turbine tower 100, the adjusting component 20 is connected to the moving vehicle 10, the rotating component 30 is connected to the adjusting component 20, and the rust removal component 40 is connected to the rotating component 30.

[0055] The adjustment assembly 20 is equipped with a first drive member 51. The adjustment assembly 20 is configured to adjust the position of the rotating assembly 30 under the action of the first drive member 51 so that the rotating assembly 30 abuts against the inner wall of the wind turbine tower 100.

[0056] The rotating assembly 30 is equipped with a second drive member 52, and the rotating assembly 30 is configured to rotate along the circumference of the wind turbine tower 100 under the action of the second drive member 52.

[0057] like Figure 3 As shown, the rust removal assembly 40 includes a grinding head 41, which is connected to the rotating assembly 30. The grinding head 41 can abut against the inner wall of the wind turbine tower 100. The grinding head 41 is configured to rotate along the circumference of the wind turbine tower 100 during the rotation of the rotating assembly 30, so that the grinding head 41 grinds the inner wall of the wind turbine tower 100.

[0058] Among them, the wind turbine tower 100 is cylindrical in shape.

[0059] The mobile cart 10 can be moved manually or by a motor. The mobile cart 10 can move the adjustment component 20, the rotation component 30, and the rust removal component 40.

[0060] The grinding head 41 grinds the inner wall of the wind turbine tower 100, which can remove the rust on the inner wall of the wind turbine tower 100.

[0061] After the rust removal equipment enters the wind turbine tower 100, the position of the rotating component 30 is adjusted by the adjusting component 20. Then, the rotating component 30 rotates along the circumference of the wind turbine tower 100. After that, the moving carriage 10 moves inside the wind turbine tower 100. Driven by the moving carriage 10 and the rotating component 30, the grinding head 41 moves along the axial direction of the wind turbine tower 100 and rotates along the circumference of the wind turbine tower 100, so that the grinding head 41 can grind the inner wall of the wind turbine tower 100. Specifically, after the mobile vehicle 10 enters the interior of the wind turbine tower 100, under the action of the first drive component 51, the adjusting component 20 adjusts the position of the rotating component 30, so that the rotating component 30 abuts against the inner wall of the wind turbine tower 100. Then, the grinding head 41 abuts against the inner wall of the wind turbine tower 100. Then, under the action of the second drive component 52, the rotating component 30 rotates along the circumferential direction of the wind turbine tower 100. Then, the mobile vehicle 10 moves inside the wind turbine tower. Driven by the mobile vehicle 10 and the rotating component 30, the grinding head 41 moves along the axial direction of the wind turbine tower 100 and rotates along the circumferential direction of the wind turbine tower 100, so that the grinding head 41 can grind the inner wall of the wind turbine tower 100.

[0062] The rust removal equipment for wind turbine towers provided in this embodiment of the invention adjusts the position of the rotating component 30 under the action of the first driving component 51 by adjusting the component 20, so that the rotating component 30 abuts against the inner wall of the wind turbine tower 100. Under the action of the second driving component 52, the rotating component 30 rotates along the circumferential direction of the wind turbine tower 100, so that the grinding head 41 grinds the inner wall of the wind turbine tower 100 along the circumferential direction of the wind turbine tower 100. The moving carriage 10 can drive the adjusting component 20, the rotating component 30 and the rust removal component 40 to move inside the wind turbine tower, so that the grinding head 41 grinds the inner wall of the wind turbine tower 100 along the axial direction of the wind turbine tower 100. This can avoid manual hand-held grinding equipment, thereby improving work efficiency and reducing labor intensity.

[0063] In one possible implementation, such as Figures 4 to 6 As shown, the adjustment assembly 20 includes a mounting tube 21 and a bidirectional lead screw 22. The first drive member 51 is mounted on the mounting tube 21. The bidirectional lead screw 22 is rotatably inserted into the mounting tube 21. The bidirectional lead screw 22 has a positive thread section 221 and a negative thread section 222. The positive thread section 221 and the negative thread section 222 are located on both sides of the axial direction of the mounting tube 21, respectively. A lead screw nut (not shown in the figure) is fitted on both the positive thread section 221 and the negative thread section 222.

[0064] The mounting pipe 21 can be a cylindrical pipe, and the axis of the mounting pipe 21 can extend along the axial direction of the wind turbine tower 100.

[0065] The axis of the bidirectional lead screw 22 coincides with the axis of the mounting tube 21. The positive thread section 221 and the negative thread section 222 of the bidirectional lead screw 22 have opposite thread directions. A smooth rod section 223 is provided between the positive thread section 221 and the negative thread section 222, and the smooth rod section 223 is rotatably mounted on the mounting tube 21. The smooth rod section 223 has no threads.

[0066] The bidirectional lead screw 22 is connected to the moving carriage 10, and the rotating assembly 30 is mounted on the lead screw nut.

[0067] like Figure 5 As shown, the first driving component 51 can be a motor. The first driving component 51 has a rotating shaft, on which a first gear 511 is mounted, and on the double-acting lead screw 22 is a second gear 224, with the first gear 511 meshing with the second gear 224. When the rotating shaft of the first driving component 51 rotates clockwise, the double-acting lead screw 22 can rotate clockwise via the first gear 511 and the second gear 224; when the rotating shaft of the first driving component 51 rotates counterclockwise, the double-acting lead screw 22 can rotate counterclockwise via the first gear 511 and the second gear 224.

[0068] In one possible implementation, such as Figure 2 and Figure 6As shown, the rotating assembly 30 includes two rotating blocks 31 and multiple connecting rod assemblies 32. The two rotating blocks 31 are rotatably mounted on two lead screw nuts, and the multiple connecting rod assemblies 32 are spaced apart along the circumferential direction of the mounting tube 21. Each connecting rod assembly 32 is hinged to the two rotating blocks 31.

[0069] The number of link assemblies 32 can be set as needed. In some examples, such as... Figure 3 and Figure 4 As shown, the rotating assembly 30 includes four link assemblies 32, each link assembly 32 including a first link 321 and a second link 322, the first link 321 and the second link 322 being hinged to two rotating blocks 31 respectively.

[0070] The length of the first link 321 can be equal to the length of the second link 322.

[0071] like Figure 4 As shown, the rotating assembly 30 also includes a mounting base 33 and a roller 34. The mounting base 33 is hinged to the first connecting rod 321 and the second connecting rod 322, respectively. The roller 34 is rotatably mounted on the mounting base 33 and is connected to the second driving member 52. In some examples, the rotating assembly 30 includes four connecting rod assemblies 32, each corresponding to one mounting base 33, each mounting base 33 corresponding to one roller 34, and each roller 34 connected to one second driving member 52. When the four rollers 34 abut against the inner wall of the wind turbine tower 100, the centers of the four rollers 34 are located on the axis of the bidirectional lead screw 22, and the centers of the four mounting bases 33 are located on the axis of the bidirectional lead screw 22.

[0072] Mounting base 33 can be a flat plate. The extending direction of mounting base 33 is parallel to the extending direction of the axis of mounting tube 21. The axis of roller 34 extends along the extending direction of the axis of mounting tube 21.

[0073] Under the action of the first driving member 51, the bidirectional lead screw 22 rotates clockwise, causing the two lead screw nuts to move closer to each other. These nuts drive the two rotating blocks 31 to move closer to each other, and the ends of the first and second connecting rods 321 and 322 of the connecting rod assembly 32 connected to the two rotating blocks 31 move closer to each other. In a direction perpendicular to the axis of the mounting tube 21, this allows the mounting base 33 and the roller 34 to move away from the bidirectional lead screw 22. Under the action of the first driving member 51, the bidirectional lead screw 22 rotates counterclockwise, causing the two lead screw nuts to move further away from each other. These nuts drive the two rotating blocks 31 to move further away from each other, and the ends of the first and second connecting rods 321 and 322 of the connecting rod assembly 32 connected to the two rotating blocks 31 move further away from each other. In a direction perpendicular to the axis of the mounting tube 21, this allows the mounting base 33 and the roller 34 to move closer to the bidirectional lead screw 22. This configuration allows the rust removal equipment for wind turbine towers to adapt to wind turbine towers 100 of different diameters.

[0074] Before the rust removal equipment for wind turbine towers enters the wind turbine tower 100, the double-acting screw 22 rotates counterclockwise. In a direction perpendicular to the axis of the mounting pipe 21, the distance between the mounting base 33 and the double-acting screw 22 is adjusted so that the rust removal equipment for wind turbine towers can enter the wind turbine tower 100 and the rotating component 30 does not contact the wind turbine tower 100.

[0075] After the rust removal equipment for the wind turbine tower enters the wind turbine tower 100, the adjustment component 20 needs to be aligned, that is, the axis of the mounting pipe 21 needs to be aligned with the axis of the wind turbine tower 100. Specifically, after the rust removal equipment enters the wind turbine tower, the adjustment component 20 is removed from the moving vehicle 10. Then, under the action of the first drive component 51, the double-acting screw 22 rotates clockwise, adjusting the distance between the mounting base 33 and the double-acting screw 22, so that the four rollers 34 of the rotating component 30 abut against the inner wall of the wind turbine tower. At this time, the axis of the mounting pipe 21 is aligned with the axis of the wind turbine tower 100, thus achieving the alignment of the adjustment component 20. After the alignment of the adjustment component 20 is achieved, the adjustment component 20 is connected to the moving vehicle 10.

[0076] The second driving component 52 can be a motor. When the wind turbine tower is derusted using a derusting device, the four rollers 34 of the rotating assembly 30 are driven to rotate under the action of the second driving component 52. Under the action of the four rollers 34 against the inner wall of the wind turbine tower 100, the four rollers 34 and the four mounting seats 33 rotate along the axis of the bidirectional lead screw 22 through two rotating blocks 31, thereby enabling the rotating assembly 30 to rotate along the circumference of the wind turbine tower 100.

[0077] Furthermore, such as Figure 4 and Figure 6As shown, at least one guide rod 23 is fixed at each end of the axial direction of the mounting tube 21. Each guide rod 23 extends along the axial direction of the mounting tube 21. The rotating assembly 30 also includes two moving blocks 35. One moving block 35 is fixed on each lead screw nut. A rotating block 31 is rotatably provided on each moving block 35. Each moving block 35 corresponds to at least one guide rod 23. The guide rod 23 passes through the moving block 35, and the moving block 35 can move along the guide rod 23.

[0078] The guide rod 23 is a cylindrical rod. Each moving block 35 can correspond to two guide rods 23, and the two guide rods 23 are parallel to each other.

[0079] During the clockwise or counterclockwise rotation of the bidirectional lead screw 22, the lead screw nut drives the moving block 35 to move along the guide rod 23, and the moving block 35 drives the rotating block 31 to move.

[0080] In one possible implementation, such as Figure 3 As shown, the rust removal assembly 40 is equipped with a third drive component 53. The rust removal assembly 40 also includes a movable seat 42. The third drive component 53 is mounted on the mounting base 33. The movable seat 42 is connected to the third drive component 53. The grinding head 41 is mounted on the movable seat 42. The third drive component 53 can move the grinding head 41 through the movable seat 42.

[0081] The third driving component 53 can be a cylinder. The third driving component 53 can move the grinding head 41 radially along the mounting tube 21 via the movable seat 42.

[0082] When the four rollers 34 of the rotating assembly 30 abut against the inner wall of the wind turbine tower 100, the third drive component 53 moves the grinding head 41 through the moving seat 42, so that the grinding head 41 abuts against the inner wall of the wind turbine tower 100.

[0083] Furthermore, such as Figure 3 and Figure 4 As shown, the rust removal assembly 40 is also equipped with a fourth drive component 54, which is mounted on the movable base 42 and connected to the grinding head 41. The fourth drive component 54 can drive the grinding head to rotate.

[0084] The fourth driving component 54 can be a motor.

[0085] When the wind turbine tower is derusted using a derusting device, the grinding head 41 is driven to rotate under the action of the fourth driving component 54. The grinding head 41 contacts the inner wall of the wind turbine tower 100, which allows the grinding head 41 to grind the inner wall of the wind turbine tower 100.

[0086] In one possible implementation, such as Figure 4 and Figure 6As shown, a limiting block 24 is provided at each end of the axial direction of the bidirectional lead screw 22. The limiting block 24 is fixedly connected to the guide rod 23 and abuts against the bidirectional lead screw 22.

[0087] The limiting block 24 is made of metal.

[0088] When the bidirectional lead screw 22 rotates counterclockwise, the two lead screw nuts move away from each other. The two lead screw nuts drive the two moving blocks 35 to move away from each other along the guide rod 23. When the moving block 35 moves to the end of the guide rod 23 away from the mounting tube 21, the moving block 35 contacts the limiting block 24. The limiting block 24 can restrict the moving block 35 on the guide rod 23 to prevent the moving block 35 from detaching from the guide rod 23.

[0089] In one possible implementation, such as Figure 2 As shown, a magnetic box 11 is provided on the mobile vehicle 10. An electromagnet is provided inside the magnetic box 11, and a contact plate 12 is provided outside the magnetic box 11. The electromagnet can attract a limiting block 24 to the contact plate 12.

[0090] When the electromagnet is energized, the limiting block 24 can be attracted to the contact plate 12. When the electromagnet is de-energized, the limiting block 24 can detach from the contact plate 12.

[0091] When the rust removal equipment for the wind turbine tower enters the wind turbine tower 100 and before the centering adjustment of the adjustment component 20 is performed, the electromagnet is de-energized; after the centering adjustment of the adjustment component 20 is performed, the electromagnet is energized, so that the moving vehicle 10 can move the adjustment component 20, the rotating component 30 and the rust removal component 40 through the magnetic box 11.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
