[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example
[0020] like Figure 1-3 As shown in the figure, an embodiment of the present invention provides a dust removal device for an axial flow fan hub, including a base plate 1, an annular seat 6, and a fan hub body 9. A housing 2 is fixedly installed on the upper part of the base plate 1, an electric push rod 4 is fixedly installed on the bottom wall of the housing 2, and a positioning plate 5 is fixedly installed on the bottom of the electric push rod 4. A dust removal component 7 is provided on the annular seat 6, and an adjustment component 3 is provided inside the housing 2. An annular hole 8 is opened in the middle of the inner wall of the annular seat 6. The fan hub body 9 is placed on the base plate 1, and the positioning plate 5 is moved down by the electric push rod 4 to fix the fan hub body 9. The dust removal component 7 can be used to clean the outer wall of the fan hub body 9 and is easy to rotate and adjust, so that the dust removal angle of the fan hub body 9 is more comprehensive. In addition, with the setting of the adjustment component 3, the dust removal position of the fan hub body 9 can be adjusted, so that the dust removal work of the fan hub body 9 is more thorough and the dust removal efficiency is improved.
[0021] The adjustment assembly 3 includes two guide rods 33 fixedly installed between the base plate 1 and the housing 2. Each guide rod 33 has a slider 34 slidably connected to it. Two threaded rods 37 are rotatably connected between the base plate 1 and the housing 2, and the threaded rods 37 are threadedly connected to the sliders 34. Rotating gears 38 are fixedly installed on the upper parts of both threaded rods 37, and a toothed belt 39 meshes between the two rotating gears 38. A support plate 31 is fixedly installed on the upper part of the housing 2, and a servo motor 32 is fixedly installed on the upper end of the support plate 31. The output shaft of the servo motor 32 is fixedly connected to one of the rotating gears 38. Both sliders 34 are fixedly connected to the annular seat 6. The servo motor 32 drives the rotating gears 38 to rotate, which in turn drives the toothed belt 39, causing the two threaded rods 37 to rotate and the sliders 34 to slide on the guide rods 33, thus adjusting the dust removal height of the fan hub body 9.
[0022] like Figure 3As shown, in some embodiments, the dust removal assembly 7 includes a support plate 71 fixedly installed on one side of the upper end of the annular seat 6. A drive motor 72 is fixedly installed on the upper end of the support plate 71. A drive gear 73 is fixedly installed on the output shaft of the drive motor 72. A rotating seat 74 is rotatably connected inside the annular hole 8. An annular plate 75 is fixedly installed on the inner wall of the rotating seat 74. Electric telescopic rods 76 are fixedly installed on both sides of the inner wall of the annular plate 75. Mounting plates 77 are fixedly installed on the telescopic ends of the two electric telescopic rods 76. A dust removal brush is provided on the inner wall of the mounting plate 77. A connecting ring 78 is fixedly installed on the upper part of the shaped plate 75, and a rack 79 is provided on the outer wall of the connecting ring 78. The fan hub body 9 is placed in the middle of the upper end of the base plate 1. The mounting plate 77 is moved closer to the fan hub body 9 by the electric telescopic rod 76, so that the cleaning brush contacts the outer wall of the fan hub body 9. The drive motor 72 drives the drive gear 73 to rotate, which drives the connecting ring 78 and the annular plate 75 to rotate with the rotating seat 74 in the annular hole 8, so that the outer wall of the fan hub body 9 can be thoroughly cleaned.
[0023] like Figure 3 As shown, in some embodiments, the drive gear 73 meshes with the rack 79; this facilitates adjustment.
