DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] Reference Figure 1-3 A wind turbine tower cleaning device comprises an arc-shaped shell 1 which is an array of three sections of a circle and connected end to end. The spliced ​​shell 1 can more conveniently sleeve the device on the outer surface of the wind turbine tower. A positioning assembly 2 for positioning the shell 1 on the outer wall of the wind turbine tower is installed at the center of the top surface and the bottom surface of the shell 1. The positioning assembly 2 comprises a guide rail, a sliding arm, a positioning motor, a positioning wheel, a driving motor and a worm gear reducer. The guide rail is fixedly mounted on the top surface or the bottom surface of the shell 1. The output end of the positioning motor is connected to the sliding arm. The positioning motor drives the sliding arm to move on the guide rail. The movement of the sliding arm can make the positioning wheel clamp the wind turbine tower. The driving motor and the worm gear reducer are both arranged on the sliding arm. The positioning wheel is connected to the output shaft of the worm gear reducer. The output end of the driving motor is connected to the input end of the worm gear reducer. The driving motor drives the positioning wheel to rotate through the worm gear reducer. The rotation of the positioning wheel can make the shell 1 rise or fall.

[0024] A T-shaped slide groove 3 is horizontally opened on the inner wall of the shell 1, and a T-shaped block 4 is slidably connected in the slide groove 3. One end of the block 4 extends out of the slide groove 3 and is fixedly connected with an arc-shaped slider 5. The T-shaped slide groove 3 cooperates with the T-shaped block 4 to ensure that the slider 5 does not fall while the slider 5 slides. An arc-shaped tooth plate 6 is fixedly connected to the side wall of the shell 1 above the slide groove 3. A driving component 7 is provided above the slider 5, which is engaged with the tooth plate 6 and drives the slider 5 to slide. The driving component 7 rotates and thereby provides power for the slider 5 to slide. Water spray ports 26 are provided at both ends of the top surface of the slider 5. Water or cleaning liquid is sprayed onto the surface of the wind turbine tower before brushing to pre-treat the dirt and facilitate subsequent brushing of the dirt. An electric telescopic rod 8 is horizontally and vertically fixedly connected to the center of the arc surface of the slider 5 away from the shell 1. A vertically downward cleaning plate 9 is hinged at one end of the electric telescopic rod 8 away from the slider 5. The electric telescopic rod 8 drives the rotatable cleaning plate 9 forward The cleaning plate 9 moves, and the bottom end of the cleaning plate 9 is subjected to an opposite force after contacting the wind turbine tower, and the cleaning plate 9 is tilted accordingly, so as to achieve the cleaning plate 9 to fit the outer surface of the inclined wind turbine tower. The top surface of the cleaning plate 9 is symmetrically fixedly connected to two support rods 10, and the top ends of the two support rods 10 are commonly fixedly connected to a horizontal plate 11. Three cleaning roller brushes 12 are equidistantly connected to rotate between the top surface of the cleaning plate 9 and the bottom surface of the horizontal plate 11, and the three cleaning roller brushes 12 are equidistantly arranged in an arc array, so as to better fit the outer surface of the wind turbine tower and improve the cleaning effect. A second motor 13 is fixedly installed on one side of the bottom surface of the horizontal plate 11, and the top end of the rotating shaft of the cleaning roller brush 12 extends out of the horizontal plate 11, and a synchronous component 14 is connected between the rotating shafts of the three cleaning roller brushes 12 and the output shaft of the second motor 13. The second motor 13 drives the cleaning roller brush 12 to rotate through the synchronous component 14, so as to achieve brushing of the outer surface of the wind turbine tower.

[0025] Reference Figure 1-3 The driving assembly 7 includes a first motor 15 fixedly mounted on the top wall inside the slider 5. The output shaft of the first motor 15 passes through the top wall of the slider 5 and is fixedly connected to a rotating rod 16. The top of the rotating rod 16 is fixedly connected to a gear 17 meshing with the toothed plate 6. The first motor 15 drives the rotating rod 16 to rotate, thereby realizing the rotation of the gear 17 on the toothed plate 6. Since the toothed plate 6 is fixedly connected to the housing 1, the slider 5 is subjected to a force in the opposite direction, thereby realizing the sliding of the slider 5 in the slide groove 3.

[0026] Reference Figure 2 , Figure 4 The synchronization component 14 includes a transmission pulley 18 fixedly connected to the top of the rotating shaft of the three cleaning roller brushes 12 and the top of the output shaft of the second motor 13. A synchronous belt 19 that rotates synchronously is connected between the four transmission pulleys 18. The four transmission pulleys 18 are rotated synchronously by the synchronous belt 19, so that the second motor 13 drives the three cleaning roller brushes 12 to rotate simultaneously.

[0027] Reference Figure 4Auxiliary rods 27 are provided on both sides of the transmission pulley 18 at the top of the rotating shaft of the cleaning roller brush 12 located in the center. The auxiliary rods 27 are rotatably connected to the top surface of the horizontal plate 11. The synchronous belt 19 passes through the auxiliary rods 27, which can increase the wrap angle of the synchronous belt 19 to the transmission pulley 18, thereby increasing the friction force of the synchronous belt 19 to the transmission pulley 18 and improving the stability of the device.

[0028] Reference Figure 2-3 A sponge block 25 is fixedly connected to the arc surface of the cleaning plate 9 away from the electric telescopic rod 8, thereby providing a buffer between the cleaning plate 9 and the outer surface of the wind turbine tower, and at the same time wiping the surface after brushing, further improving the cleaning effect.

[0029] Reference Figure 1 , Figure 5 A boss 20 is vertically provided at the upper end of one side of the shell 1, and a groove 21 is correspondingly provided at the upper end of the other side. The adjacent shells 1 are connected end to end through the boss 20 and the groove 21. When connecting adjacent shells 1, the boss 20 is aligned with the groove 21 to achieve the connection between the shells 1. Threaded holes 22 are provided at both ends of the top surface of the shell 1. A metal block 23 for connecting the two adjacent shells 1 is provided between them. Bolts 24 are vertically connected at both ends of the metal block 23, and the bolts 24 are threadedly connected in the threaded holes 22. By fixing the metal block 23, the connection between the shells 1 can be made more stable, and the flushness of the upper surfaces of the adjacent shells 1 can be ensured.

[0030] Working principle:

[0031] When the wind turbine tower cleaning device is used, three shells 1 are sleeved on the outside of the wind turbine tower, and the protruding columns 20 of the adjacent shells 1 are aligned with the grooves 21 and inserted. After the three shells 1 are connected, the bolts 24 on the metal block 23 are screwed into the threaded holes 22. After completion, the positioning component 2 is used to position the device on the outer surface of the wind turbine tower, the electric telescopic rod 8 is turned on and the cleaning plate 9 is driven to move forward. After the bottom end of the cleaning plate 9 contacts the wind turbine tower, it is subjected to an opposite force, and the cleaning plate 9 is tilted and fits on the outer surface of the wind turbine tower. The cleaning liquid is sprayed on the surface of the wind turbine tower by a nozzle. Then, the second motor 13 is turned on, and the four drive pulleys 18 are rotated synchronously with the synchronous belt 19, so as to drive the three cleaning roller brushes 12 to rotate simultaneously. At the same time, the first motor 15 is turned on and drives the rotating rod 16 to rotate, so as to realize the rotation of the gear 17 on the tooth plate 6. The slider 5 is therefore subjected to forces in opposite directions, so that the slider 5 slides in the slide groove 3. When the slider 5 slides to the end in the slide groove 3, the positioning assembly 2 is used to lift the device to the uncleaned height, and the second motor 13 is reversed to realize a new round of cycle, thereby completing the entire cleaning process of the outer surface of the wind turbine tower.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
