They are mainly composed of core components such as blades, generators, direction regulators, towers, speed limiting safety mechanisms, and energy storage devices. Usually, wind turbines are erected in areas with rich wind energy resources. These areas often have harsh environments. The blades and towers are exposed to the outdoors for a long time and are easily eroded by wind and sand. The outer walls are also more prone to rust. These factors not only affect the operating efficiency of the unit, but may also cause safety hazards. In order to reduce operation and maintenance costs and ensure the safe and stable operation of the unit, it is very necessary to clean the outer wall of the blades regularly; In the field of wind power generation, cleaning wind turbine blades is of vital importance. However, existing drones face many challenges when cleaning wind turbine blades at high altitudes.

[0019] The following will be a clear and complete description of the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Implementation Cases: See also Figures 1 to 5 The present invention provides a technical solution: a wind turbine blade-embracing magnetic suction cleaning drone, comprising: The drone body 1 is the core structure of the entire device and consists of an upper body 7, a lifting drive system 2, a hydraulic connection device 3, an intelligent control unit 4 and a cleaning execution module 5; The upper body 7 serves as a bearing platform and provides an installation base for other components. A plurality of hydraulic connectors 17 are evenly distributed on the lower outer surface thereof for connecting to the hydraulic telescopic push rod 8 to realize the lifting and lowering adjustment function.

[0021] The lifting drive system 2 is connected to the outer surface of the upper body 7 and is a key component for driving the drone body 1 to rise and fall. It mainly includes flying wings 11 and wing brackets 13. There are multiple groups of wing brackets 13. The ends of each group of wing brackets 13 are equipped with connecting adapters 14, which are adapted to the rotating head 10 of the upper body 7 and connected via a connecting fixed pin 16. In addition, each wing bracket 13 is equipped with a power motor 12 at one end away from the connection adapter 14. The output end of the power motor 12 is connected to the flying wing 11 and is electrically connected to the intelligent control unit 4, thereby achieving precise control of the wing 11 and ensuring the smooth rise and fall of the drone.

[0022] The hydraulic connection device 3 is arranged at the lower part of the upper body 7 and consists of four hydraulic telescopic push rods 8 and four movable joint hinges 15. The hydraulic telescopic push rods 8 are equipped with pistons and hydraulic rods. The tail end of the hydraulic rod is convex, while the shape of the movable joint hinge 15 is concave. The two are tightly connected by a connecting fixed pin 16; This structural design not only achieves a stable connection between the upper and lower bodies, but also provides a flexible movement space for the cleaning execution module 5.

[0023] The bottom of the hydraulic rod at the lower end of the hydraulic telescopic push rod 8 is connected to the four hinges of the lower operating platform 9 by connecting and fixing pins 16, which further enhances the stability of the connection.

[0024] The intelligent control unit 4 is the "brain" of the drone. It is set inside the upper body 7 and is electrically connected to the lifting drive system 2 and the hydraulic connection device 3. It is powerful and can accurately control the coordinated work of various components.

[0025] In addition, a second intelligent control unit 4 is provided at the center of the lower operating platform 9, which is linked to the first intelligent control unit 4. A joint is provided on the lower end surface to connect with the cleaning control push rod 19 below, thereby realizing precise control of the cleaning execution module 5.

[0026] The cleaning execution module 5 is a key component of the present invention, which mainly adopts the connecting rod principle, and the operation of the cleaning control push rod 19 drives the gripping mechanism to move; A flexible brush 21 is provided inside the gripping mechanism, and a cavity is provided inside for loading the cleaning liquid, which is connected to the flexible brush 21 to ensure that the cleaning liquid can act evenly on the surface of the blade; A travel drive motor 23 is provided at the lower end of the gripping mechanism. The output end of the travel drive motor 23 is connected to four groups of symmetrically distributed magnetic adsorption moving wheels 22. Magnets are installed on the magnetic adsorption moving wheels 22 to cooperate with the fixed cleaning part to enable them to move stably on the surface of the fan blades and achieve all-round cleaning.

[0027] Working process of the fan blade-embracing magnetic cleaning drone of the present invention: Lifting and hovering: The lifting drive system 2 precisely controls the drone body 1 to perform smooth lifting and lowering operations. When the drone reaches the specified height or approaches the wind turbine blades, it immediately enters the hovering state.

[0028] Hydraulic adjustment: The intelligent control unit 4 cleverly controls the hydraulic connection device 3, driving each hydraulic telescopic push rod 8 to accurately extend and retract to the preset length, thereby pushing the lower-level mechanisms to accurately reach the designated position. At this time, the cleaning execution module 5 is in a vertical and open state.

[0029] Clamping the blades: Through the precise control of the lifting drive system 2, the drone body 1 moves slowly, so that the cleaning execution module 5 approaches the side of the blade smoothly until the blade smoothly enters the opened cleaning execution module 5. At this time, the cleaning control motor 19 starts and drives the cleaning execution module 5 to precisely clamp the blade. At the same time, the magnetic walking wheels are firmly adsorbed on the surface of the blade, effectively preventing the drone from falling and ensuring the safety and stability of the cleaning process.

[0030] Cleaning operation: After the cleaning execution module 5 firmly clamps the blade, the washing liquid in the cleaning solution storage tank 20 flows accurately to the flexible brush 21, making it fully infiltrated. Then, the walking drive motor 23 is started, driving the magnetic adsorption moving wheel 22 to move smoothly along the surface of the blade. The flexible brush 21 closely adheres to the surface of the blade during the movement, efficiently performing the cleaning operation, thoroughly removing the dirt on the blade, and restoring the cleanliness and gloss of the blade.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
