[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1 As shown;

[0025] A wind turbine tower outer wall moving device comprises a nacelle 1, blades 2 mounted on an output shaft of the nacelle 1, and a tower body 4 fixedly connected to the bottom surface of the nacelle 1.

[0026] In this implementation scheme: because most of the units in China currently need a hanging basket to work when repairing blades or working outside the tower, the hanging basket is extremely dangerous when working, the working surface is unstable, the shaking is extreme, and the working environment requirements are extremely high. The staff has a small working surface when working in the hanging basket. In order to solve this technical problem, a mobile component 12 is added on this basis.

[0027] More specifically:

[0028] like Figures 1 to 6 As shown:

[0029] In combination with the above content: it also includes a moving component 12 arranged on the surface of the tower body 4;

[0030] The mobile component 12 includes a platform 7 installed on the surface of the tower body 4, two limit plates 10 are fixedly connected to the surface of the platform 7, two winches 6 are fixedly connected to the platform 7 toward the cabin 1, a traction rope 3 is provided on the surface of the winch 6, and two hanging wheels 14 compatible with the winch 6 are fixedly connected to the bottom surface of the cabin 1.

[0031] In this embodiment: since a platform 7 is provided on the surface of the tower body 4, the staff can start the winch 6, and the winch 6 makes the platform 7 close to the cabin 1 through the cooperation of the traction rope 3 and the hanging wheel 14. This design can improve the safety of the staff when repairing the blades 2 and working outside the tower body 4.

[0032] It should be noted that before installing the platform 7, the blades 2 need to be perpendicular to the tower body 4 and the impeller lock needs to be locked to ensure safety and reliability.

[0033] Going further:

[0034] In an optional embodiment, a slide groove 13 is opened on the surface of the platform 7, and eight tower pulleys 5 are arranged in the slide groove 13. The rotating shaft of each tower pulley 5 is fixedly connected to the platform 7, and the roller of each tower pulley 5 is in contact with the surface of the tower body 4.

[0035] In this embodiment, since a slide groove 13 is provided on the surface of the platform 7 and a tower pulley 5 is provided in the slide groove 13, the staff can reduce the friction force during the movement of the platform 7 through the tower pulley 5 and improve the stability during the movement.

[0036] It should be noted that the eight tower pulleys 5 are respectively and centrally symmetrically arranged on the surface of the platform 7 .

[0037] Going further:

[0038] In an optional embodiment, the minimum distance between the two limiting plates 10 is greater than the cross-sectional length of the blade 2 .

[0039] In this embodiment, since two limit plates 10 are fixedly connected to the surface of the platform 7, the staff can limit the blade 2 through the limit plates 10. This design can further improve the safety of the staff during maintenance.

[0040] Going further:

[0041] In an optional embodiment, two buckle bodies 11 are symmetrically arranged on the surface of the platform 7, a telescopic groove 16 is opened on the inner side of the buckle body 11, a card plate 15 is inserted on the inner side of the telescopic groove 16, and a limiting block 18 is fixedly connected on both sides of the card plate 15, a limiting groove 17 is opened on the inner side of the buckle body 11, the limiting block 18 is slidingly connected to the buckle body 11 through the limiting groove 17, and the limiting groove 17 is communicated with the telescopic groove 16, a screw rod 19 is arranged in the telescopic groove 16, and the screw rod 19 is rotatably connected to the buckle body 11 through the telescopic groove 16, the screw rod 19 passes through the card plate 15, and is threadedly connected to the card plate 15.

[0042] In the present embodiment, since two buckle bodies 11 are symmetrically arranged on the surface of the platform 7, when the platform 7 is not moved, the staff can rotate the screw rod 19 in the buckle body 11. The rotation of the screw rod 19 causes the card plate 15 to slide with the buckle body 11 in the telescopic groove 16. During this process, the card plate 15 is limited by sliding in the limiting groove 17 through the limiting block 18. The platform 7 is positioned due to the sliding of the card plate 15. This design can further improve the stability of the device.

[0043] It should be noted that the surface of the clamping plate 15 is matched with the surface of the tower body 4 .

[0044] Going further:

[0045] In an optional embodiment, a bevel gear 20 is fixedly connected to the surface of the screw rod 19, a transmission shaft 22 is provided on the surface of the buckle body 11, and the transmission shaft 22 passes through the buckle body 11 and is rotatably connected to the buckle body 11. One end of the transmission shaft 22 located on the inner side of the buckle body 11 is fixedly connected to a bevel gear 21, and the bevel gear 20 and the bevel gear 21 are meshed with each other, and the upper end of the transmission shaft 22 is fixedly connected to a rotating handle 23.

[0046] In this embodiment: because bevel gear 1 20 and bevel gear 2 21 are meshed, the staff can rotate the rotating handle 23, and the rotating handle 23 rotates through the transmission shaft 22 to rotate the bevel gear 2 21, so that the bevel gear 1 20 drives the screw rod 19 to rotate. With this design, it is convenient for the staff to use the clamping plate 15 to position the platform 7.

[0047] Going further:

[0048] In an optional embodiment, a guardrail 8 is fixedly connected to the surface of the platform 7 .

[0049] In this embodiment, since the surface of the platform 7 is provided with a guardrail 8, this design can further increase the safety of the device.

[0050] Working principle: Since a platform 7 is provided on the surface of the tower body 4, the staff can start the winch 6, and the winch 6 makes the platform 7 close to the nacelle 1 through the cooperation of the traction rope 3 and the hanging wheel 14. This design can improve the safety of the staff when repairing the blades 2 and working outside the tower body 4. Since a slide groove 13 is provided on the surface of the platform 7, and a tower pulley 5 is provided in the slide groove 13, the staff can reduce the friction during the movement of the platform 7 through the tower pulley 5, and improve the stability during the movement. Since two limit plates 10 are fixedly connected to the surface of the platform 7, the staff can limit the blade 2 through the limit plates 10. This design can further improve the safety of the staff during maintenance. Since two buckle bodies 11 are symmetrically provided on the surface of the platform 7, the staff can limit the blade 2 on the flat When the platform 7 is not moved, the screw rod 19 in the buckle body 11 can be rotated. The rotation of the screw rod 19 causes the card plate 15 to slide with the buckle body 11 in the telescopic groove 16. During this process, the card plate 15 is limited by sliding in the limit groove 17 through the limit block 18. The platform 7 is positioned due to the sliding of the card plate 15. This design can further improve the stability of the device. Since the bevel gear 1 20 and the bevel gear 2 21 are meshed, the staff can rotate the rotating handle 23, and the rotating handle 23 rotates through the transmission shaft 22 to rotate the bevel gear 21, so that the bevel gear 1 20 drives the screw rod 19 to rotate. This design can facilitate the staff to use the card plate 15 to position the platform 7. Since the surface of the platform 7 is provided with a guardrail 8, this design can further increase the safety of the device.
