Embodiment 1

[0024] Reference Figure 1-Figure 4 The adjusting mechanism 9 includes a screw rod 91 rotating in the transparent protective cover 4 through a bearing, the outer surface of the screw rod 91 is threadedly connected with a mounting box 92, a motor 94 is fixed to the side of the transparent protective cover 4, and the screw rod 91 is connected to the output shaft end of the motor 94.

[0025] Reference Figure 1-Figure 4 The adjustment mechanism 9 also includes a limiting rod 93 fixed in the transparent protective cover 4, and the mounting box 92 slides on the outer surface of the limiting rod 93.

[0026] In the utility model, when in use, the wind turbine hub is placed in the limiting shell 2, a fixing device can be installed in the limiting shell 2 to fix the hub, the cylinder is started, the transparent protective cover 4 is driven to move down, the transparent protective cover 4 is snapped into the card slot 3, so that a sealed space is formed around the hub, and the hub can be polished by installing a polishing mechanism in the transparent protective cover 4. This is a prior art, so it will not be described in detail here. During polishing, a large amount of debris and dust will be generated. By starting the vacuum cleaner 5, suction is generated at the vacuum head 7, and the debris and dust are removed through the vacuum cleaner 5. The vacuum head 7 and the hose 8 are sucked into the water tank 6 to mix with the water placed in the water tank 6 in advance. This design can remove debris and dust. Through the setting of the transparent protective cover 4, the dust and debris can be gathered together to prevent dust and debris from flying around and affecting the polishing workshop. When sucking debris and dust, the motor 94 can be started to drive the screw 91 to rotate, and the limiting rod 93 can be cooperated with to drive the installation box 92 and the vacuum head 7 to move left and right, thereby improving the suction range of the vacuum head 7 and removing debris and dust better.

[0028] Reference Figure 1-Figure 4 The swing mechanism 10 includes a rotating rod 101 that rotates in the mounting box 92 through a bearing, and a cam 102 is fixed to the outer surface of the rotating rod 101.

[0031] In the utility model, when sucking up debris and dust, the rotating rod 101 can be driven to rotate by starting the second motor 103, and the rotating rod 101 drives the cam 102 to rotate. When the cam 102 rotates to contact with the mounting plate 104, downward pressure is applied to the mounting plate 104 to compress the reset spring 105. Since the mounting plate 104 is rotatably connected to the mounting box 92, the mounting plate 104 and the dust collector head 7 can be driven to swing upward. When the cam 102 is away from the mounting plate 104, the elastic force of the reset spring 105 drives the dust collector head 7 to swing downward. Therefore, when the cam 102 rotates, the dust collector head 7 can be driven to swing up and down, thereby increasing the suction range of the dust collector head 7 again and achieving a better removal effect.
