[0002] The wind turbine tower is an important component of the wind turbine generator set, supporting the entire nacelle and blades. Therefore, maintaining its structural integrity and functionality is very important. Due to its outdoor environment, the surface of the tower is often covered with dust, mud and other substances. If the lubricating oil or coolant leaks in the nacelle, oil stains and impurities will also accumulate on the surface of the tower. If these foreign objects and dirt are not cleaned in time, they will not only affect the appearance of the tower, but also corrode the surface of the tower and weaken its structural strength.

[0003] Currently, various specialized tower cleaning devices and equipment have emerged, but they primarily achieve tower cleaning through structures such as roller brushes or disc brushes. These structures are effective at removing dust, mud, and other foreign matter adhering to the tower surface, but they are generally less effective at cleaning stubborn dirt such as oil stains and grime formed by mixed dust.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0047] This application provides a tower cleaning mechanism, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0048] See Figure 1 In one embodiment, the tower cleaning mechanism includes: a main support 1 for mounting on a cleaning device; a roller brush assembly 2 disposed on the main support 1; and a scraper assembly 3, which includes a scraper 31 and an elastic element 37, the elastic element 37 being used to press the scraper 31 against the outer wall of the tower 100.

[0049] In this embodiment, by setting the roller brush assembly 2 and the scraper 31 on the main support 1, the roller brush assembly can clean the dust and mud on the outer wall of the tower, and the scraper assembly can remove oil stains and dirt, realizing a targeted cleaning method for different foreign objects in the tower and improving the cleaning effect of the tower; the elastic element 37 can be used to press the scraper 31 against the outer wall of the tower 100 to ensure the scraping effect.

[0050] In some embodiments, the roller brush assembly 2 may be located above the scraper assembly 3. For example, the roller brush assembly 2 is installed on the upper part of the main support 1, and the scraper assembly 3 is installed on the lower part of the main support 1. When the tower cleaning mechanism cleans the tower 100 from bottom to top, the roller brush assembly 2 first removes loose soil and other particles, and then the scraper assembly 3 removes stubborn dirt such as oil stains. This working method can effectively avoid the wear of dust and particles on the outer wall of the tower during the scraping operation, and ensure the integrity and aesthetics of the paint surface on the outer wall of the tower.

[0051] See Figure 1 , Figure 3 and Figure 5 Specifically, the scraper assembly 3 further includes: a plurality of support rods 35, which are inserted into corresponding mounting holes 15 on the main support 1; the main body of the support rod 35 is located on the side of the main support 1 facing the tower, and the protruding part of the support rod 35 is located on the side of the main support 1 away from the tower; the scraper 31 is installed at the end of the main body; a limiting ring 36 is fixed on the main body of the support rod 35; the elastic element 37 is sleeved on the main body between the limiting ring 36 and the main support 1; and a limiting element 38 is provided on the protruding part of the support rod 35 to restrict the support rod 35 from being pulled out of the mounting hole 15.

[0052] In this embodiment, the support rod 35 slides into the mounting hole 15, and the diameter of the support rod 35 is slightly smaller than the inner diameter of the mounting hole 15. After the support rod 35 passes through the main support 1, its protruding part passes through a limiting member 38. The limiting member 38 can be an elastic pin, used to limit the end of the support rod 35. One end of the elastic member 37 abuts against the limiting ring 36, and the other end abuts against the main support 1. The elastic member 37 can keep the scraper 31 pressed against the outer wall of the tower 100 when the scraper 31 is working.

[0053] Optionally, the scraper 31 can be made of an elastic material. Figure 6 Because the outer wall of the tower 100 is arc-shaped, the elastic scraper 31 can bend to adapt to the shape of the outer wall of the tower 100 and can scrape and wash closely against the outer wall of the tower 100.

[0054] Optionally, the two ends of the scraper 31 are respectively fixed to the ends of the main body of the corresponding support rod 35.

[0055] Further, see Figure 1 The scraper 31 has several transverse protrusions 311 on its surface facing the tower. The transverse protrusions 311 can ensure effective contact between the scraper 31 and the outer wall of the tower 100.

[0056] Furthermore, for ease of disassembly and assembly of scraper 31, see [link / reference]. Figure 3 and Figure 4Optionally, mounting plates 32 are respectively embedded on the surfaces of the scraper 31 facing the main bracket 1 at both ends; the mounting plates 32 are provided with fixing holes 33; a connecting plate 34 is fixed to the end of the main body of the support rod 35; the connecting plate 34 and the mounting plate 32 are detachably connected by a fastener.

[0057] Optionally, the mounting plate 32 can be made of metal, and its exposed surface can be flush with the back of the scraper 31. The upper and lower parts of the exposed surface of the mounting plate 32 can have symmetrically opened fixing holes 33, which can be threaded blind holes. The connecting plate 34 can be the same size as the mounting plate 32, and the two are connected movably by bolts. Since the scraper 31 needs to be replaced after a specified working time, this design facilitates quick replacement of the scraper 31 during field operations. The midpoint of the connecting plate 34 can be welded to the end of the support rod 35.

[0058] Further, see Figure 1 , Figure 2 and Figure 3 The main support 1 includes a pair of support arms 11; the roller brush assembly 2 includes: a roller brush 21, both ends of which are rotatably mounted on the corresponding support arms 11; a reducer 22 connected to one end of the roller brush 21; and a motor 23 for driving the roller brush 21 to rotate via the reducer 22. The reducer 22 and the motor 23 can be bolted to the outside of the support arms 11. After the motor 23 starts, it transmits motion and power to the roller brush 21 through the reducer 22.

[0059] Optionally, the support arm 11 is provided with a circular through hole 12; a bearing 13 for engaging with the end of the roller brush 21 is installed in the circular through hole 12. The bearing 13 can be an angular contact ball bearing to ensure that it can withstand forces in both radial and axial directions, and the outer ring of the bearing 13 is interference-fitted with the circular through hole 12.

[0060] See Figure 2 Furthermore, the main support 1 includes: a vertical mounting plate 16; a support arm 11 disposed on the side of the vertical mounting plate 16 facing the tower; and a horizontal mounting plate 17 disposed on the side of the vertical mounting plate 16 away from the tower. The horizontal mounting plate 17 is provided with a plurality of sliding sleeves 14 for cooperation with cleaning equipment. The sliding sleeves 14 facilitate the assembly and disassembly of the main support 1 from the cleaning equipment. There can be four sliding sleeves 14, located at the four corners of the horizontal mounting plate 17.

[0061] In one application scenario, during operation, the main support 1 is installed on the tower cleaning equipment, and then the cleaning equipment is started and moved on the tower. Due to the upper and lower arrangement of the roller brush assembly and the scraper assembly, during cleaning, after the roller brush 21 cleans the dust and sand attached to the outer wall of the tower, the scraper 31 then removes oil stains and dirt. Since the roller brush 21 has already cleaned the dust and sand, when the scraper 31 is in action, it only scrapes off oil stains and dirt, and there will be no particulate matter abrading the outer wall of the tower, thus ensuring the integrity and aesthetics of the paint surface on the outer wall of the tower.

[0062] It should be noted that all the devices (parts whose specific structures are not specified) selected in this application are general standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
