Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0049] A wind turbine is a device that uses wind power to drive the windmill blades to rotate, and then uses a speed increaser to increase the blade rotation speed to generate electricity.
[0050] After a wind turbine is used outdoors for a long time, dust or other impurities will accumulate on the surface of the blades. The deposited impurities will increase the weight of the blades, increase the resistance during the rotation of the blades, and affect the power generation efficiency.
[0051] Based on this, an embodiment of the present application discloses a blade cleaning device for a wind turbine generator set to clean the wind turbine generator set and ensure the power generation efficiency of the wind turbine generator set.

[0056] Among them, the hydraulic rod 21 is fixedly connected to the trolley body 1, and the hydraulic rod 21 is fixedly connected to the fixed frame 22, the cleaning roller 23 is rotationally connected to the fixed frame 22, the driving motor 24 is fixedly connected to the fixed frame 22, and the output shaft of the driving motor 24 is transmission-connected to the cleaning roller 23.
[0057] Optionally, one end of the trolley body 1 has a bracket 11. Exemplarily, the bracket 11 is a support plate integrally formed with the trolley body 1. The hydraulic rod 21 is perpendicular to the bracket 11 and fixedly connected to the bracket 11. The connection between the hydraulic rod 21 and the bracket 11 includes but is not limited to screw connection or clamping.
[0058] The fixing frame 22 is a U-shaped structure, including a crossbeam, a first vertical plate and a second vertical plate. The first vertical plate is connected to one end of the crossbeam in the direction of extension, and the second vertical plate is connected to the other end of the crossbeam in the direction of extension. The first vertical plate and the second vertical plate intersect with the crossbeam and form a U-shaped structure relative to each other. The first vertical plate and the second vertical plate are arranged along the width direction. The width direction, the running direction and the height direction in this article are perpendicular to each other. When the blade cleaning device is cleaning the blade, the width direction in this article is the same as the width direction of the blade.

[0061] The cleaning assembly 2 of the embodiment of the present application uses a driving motor 24 to drive the cleaning roller 23 to rotate, thereby achieving mechanized cleaning and reducing the labor intensity of the operator.

[0062] The suspension device 3 is arranged on the upper surface of the trolley body 1 , and the suspension device 3 includes: a rotating block 31 and an anti-drop rope 32 .
[0063] The rotating block 31 is rotatably connected to the upper surface of the trolley body 1, and an anti-drop rope 32 is wound inside the rotating block 31.

[0064] During the cleaning process of the blades, the anti-drop rope 32 is fixedly connected to the wind power tower. Exemplarily, the connection method of the anti-drop rope 32 to the wind power tower includes but is not limited to a binding connection. Then the blade cleaning device is placed on the blade, and the blade cleaning device is started to clean the blade.

Exemplarily, the bogie 42 is a U-shaped structure, and the cross plate of the bogie 42 is rotatably connected to the trolley body 1, and the connection method between the cross plate of the bogie 42 and the trolley body 1 includes but is not limited to being connected through a first rotating shaft; the two vertical plates of the bogie 42 are connected to a second rotating shaft, and the steering wheel 41 is inserted between the two vertical plates and rotatably sleeved on the second rotating shaft. It can be understood that the rotation plane of the bogie 42 and the trolley body 1 is perpendicular to the rotation plane of the steering wheel 41 and the bogie 42.
[0069] In some embodiments, there are two bogies 42 , which are distributed on both sides of the trolley body 1 along the width direction. Each bogie 42 is provided with a steering wheel 41 .
[0070] The telescopic plate 45 is fixedly connected to the bogie 42 on one side along the running direction of the blade cleaning device, and is hingedly connected to the rack 43 on the other side along the running direction of the blade cleaning device, and the length of the telescopic plate 45 can be changed.
[0071] Both ends of the rack 43 along the width direction of the blade cleaning device may be provided with telescopic plates 45 , respectively, and the telescopic plates 45 are connected to the bogies 42 on the corresponding sides.
[0072] The steering motor is fixed inside the vehicle body 1 , and the output shaft of the steering motor is fixedly connected to the gear 44 , and the gear 44 and the rack 43 are meshed for transmission.
[0073] During the rotation of the steering motor drive gear 44, the rack 43 is driven to move in the width direction of the figure, thereby driving one end of the telescopic plate 45 to move, and the end of the telescopic plate 45 connected to the bogie 42 to move, thereby changing the direction of the bogie 42.
[0074] The steering assembly 4 of the blade cleaning device of the embodiment of the present application can realize the direction of the trolley body 1 during the movement, thereby realizing the cleaning of different positions of the blades, and can adjust the cleaning position of the cleaning roller 23 as needed.
[0075] like Figure 2 As shown, along the running direction, the diverting assembly 4 is located between the moving assembly 5 and the cleaning assembly 2.
[0076] See also Figure 5 and Figure 6 As shown, the moving assembly 5 includes: a moving wheel 51 , a rotating rod 52 and a moving driving motor 53 .
[0077] The rotating rod 52 is arranged along the width direction of the trolley body 1, and the rotating rod 52 penetrates the trolley body 1 along the width direction and is rotatably connected to the trolley body 1. In some embodiments, the rotating rod 52 is arranged parallel to the rack 43.
[0078] The rotating rod 52 is sleeved with a first bevel gear 521 . Exemplarily, the first bevel gear 521 is disposed at a middle position of the rotating rod 52 along the axial direction of the rotating rod 52 .
[0079] A moving wheel 51 is respectively disposed at both ends of the rotating rod 52, and the moving wheel 51 is fixedly connected to the rotating rod 52. Exemplarily, the moving wheel 51 and the rotating rod 52 can be connected by a spline.
[0080] The mobile driving motor 53 is fixed inside the trolley body 1, and a second bevel gear 531 is provided at the end of the output shaft of the mobile driving motor 53. The first bevel gear 521 and the second bevel gear 531 are meshed and transmitted, so that the mobile driving motor 53 can drive the rotating rod 52 to rotate.
[0081] The blade cleaning device of the embodiment of the present application uses the moving component 5 to drive the trolley body 1 to move, and the driving direction of the moving component 5 is the running direction of the trolley body 1. The steering component 4 is used to turn the moving direction of the trolley body 1, so as to avoid the position of the blade or clean any position on the blade, thereby improving the application range of the blade cleaning device. It can be understood that the trolley body 1 is driven by the moving component 5 and the steering component 4, so as to adapt to the continuous cleaning of the blade position by the cleaning component 2.
[0082] Combination Figure 2 and Figure 7 As shown, the limiting mechanism 7 includes: a fixing plate 71 , a first limiting wheel assembly 72 and a second limiting wheel assembly 73 .
[0083] Among them, the fixing plate 71 is fixed inside the trolley body 1. Of course, it can also be understood that the fixing plate 71 is a part of the trolley body 1 during the processing.
[0084] The first limiting wheel assembly 72 and the second limiting wheel assembly 73 have the same structure. The first limiting wheel assembly 72 includes: a first winding motor 721, a first winding wheel 722, a first clamping wheel 723 and a first connector 724. The second limiting wheel assembly 73 includes: a second winding motor 731, a second winding wheel 732, a second clamping wheel 733 and a second connector (not shown in the figure).
[0085] The first winding motor 721 is fixed to the lower surface of the trolley body 1 in the height direction, and the output shaft of the first winding motor 721 is transmission-connected with the first winding wheel 722, so that the first winding motor 721 drives the first winding wheel 722 to rotate. Exemplarily, the output shaft of the first winding motor 721 is fixedly connected with the rotating shaft of the first winding wheel 722 via a coupling.
[0086] A connecting rope is wound around the first winding wheel 722 , and the size and material of the connecting rope can be set according to different needs and are all within the protection range.
[0087] The free end of the connecting rope wound on the first winding wheel 722 is fixedly connected to the first connecting head 724, and the connection method between the connecting rope and the first connecting head 724 includes but is not limited to bonding.
[0088] The connecting rope of the first winding wheel 722 passes through the first clamping wheel 723 and is connected to the first connecting head 724. The first connecting head 724 is limited against the side of the first clamping wheel 723 away from the first winding wheel 722, and the first connecting head 724 can move in a direction away from the first clamping wheel 723. The first clamping wheel 723 and the first connecting head 724 are both located outside the trolley body 1.
[0089] The structure of the second limiting wheel assembly 73 is the same as that of the first limiting wheel assembly 72 . Therefore, the connection method of the second limiting wheel assembly 73 can refer to the above description.
[0090] It should be noted that the second winding motor 731 of the second limiting wheel assembly 73 is fixed on the fixed plate 71, and the first winding wheel 722 and the second winding wheel 732 are arranged adjacent to each other, and the first winding motor 721 and the second winding motor 731 are arranged symmetrically in the height direction with respect to the first winding wheel 722 and the second winding wheel 732.

[0092] When the position of the trolley body 1 is limited by the limiting mechanism 7 disclosed in the embodiment of the present application, the operator pulls the first connector 724 and the second connector. In the process of pulling the connecting rope, the first clamping wheel 723 and the first connector 724 move away from each other until the first clamping wheel 723 and the first connector 724 reach the opposite sides of the blade respectively. Figure 7 The vertical state is switched to the horizontal state, and the slots of the first clamping wheel 723 and the first connecting head 724 are respectively inserted into the corresponding sides of the blade; then the first connecting head 724 and the second connecting head are continuously pulled until the connecting rope surrounds the blade, and the first connecting head 724 and the second connecting head are detachably fixedly connected, exemplarily, by a threaded connection; the first winding wheel 722 and the second winding motor 731 are started, the first winding wheel 722 winds up the connecting rope wrapped around itself, and the second winding wheel 732 winds up the connecting rope wrapped around itself, so that the first connecting head 724 and the second connecting head tighten the connecting rope, so that the first clamping wheel 723 and the second clamping wheel 733 clamp the blade to prevent the blade cleaning device from moving away from the blade.
[0093] The blade cleaning device of the embodiment of the present application can limit the moving position of the trolley body 1 by setting a cleaning device, thereby preventing the trolley body 1 from separating from the blades and affecting the cleaning effect of the cleaning roller 23.
[0094] In some embodiments, a battery is provided in the trolley body 1 for supplying power to the motor in the trolley body 1 .
[0095] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
