[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] like Figure 1-10 As shown, an intelligent maintenance platform that utilizes the characteristics of the wind turbine blade itself includes a mounting base 4, a first clamping platform 5 and a second clamping platform 6. The first clamping platform 5 and the second clamping platform 6 are movably connected to the mounting frame 13 through a clamping drive device. The mounting frame 13 is fixed on the upper and lower sides of the mounting base 4. The first clamping platform 5 and the second clamping platform 6 are installed with a fixing device 8 and a moving device 9. The first clamping platform 5 or the second clamping platform 6 is provided with at least one group of load mechanical arm assemblies or other maintenance working conditions devices. Specific other maintenance working conditions devices include ultrasonic flaw detection equipment, blade surface cleaning equipment or blade surface grinding and repair equipment, etc. Different functions are achieved by connecting different devices; when in use, the two groups of the fixing devices 8 are clamped on both sides of the wind turbine blade, and the moving device 9 drives the intelligent maintenance platform as a whole to move along the trailing edge position of the blade. Specifically, the load manipulator assembly includes a manipulator 14 and a manipulator arm 15 . The manipulator 14 is connected to the free end of the manipulator arm 15 , and the fixed end of the manipulator arm 15 is positioned and connected to the cantilever 501 of the first clamping platform 5 or the second clamping platform 6 .

[0039] It also includes a docking guide device 7, which is installed on the working side of the mounting seat 4, and the docking guide device 7 corresponds to the trailing edge of the wind turbine blade. The docking guide device 7 completes the docking and guiding operations when used with the wind turbine blade 16; the non-working side of the mounting seat 4 is connected to a two-way winch 2 for multi-platform cooperation and a mounting bracket 1 for connecting to a drone.

[0040] like Figure 2-4 As shown, the docking guide device 7 includes a stop block 701 and a first spring 702. One end of the first spring 702 is fixed to the mounting base 4 via a first connecting seat 705. The other end of the first spring 702 is connected to the stop block 701 via a support frame 703. A positioning post 704 is connected to the side of the support frame 703 or the first connecting seat 705 near the first spring 702. The other end of the positioning post 704 is free and has a clearance fit with the first connecting seat 705 or the support frame 703. The clearance value is set to meet the requirements of the change in the trailing edge contour of the wind turbine blade during movement. The laser ranging sensor and camera assembly 3 are also included. The laser ranging sensor and camera assembly 3 are mounted on the inner side of the mounting base 4, and the working surfaces of the laser ranging sensor and camera assembly 3 are aligned with the trailing edge of the wind turbine blade 16. The design of the optical ranging sensor and camera assembly 3 allows the alignment of the trailing edge of the wind turbine blade 16. Ensure that the intelligent maintenance platform can dock with the trailing edge of the wind turbine blade; specifically, through the design of parts such as the limit block 701 and the first spring 702, an elastic adaptive guiding system is formed after being positioned and connected to the fixed seat.

[0041] Specifically, the limiting block 701 is configured as a sheave, and the sheave is rotatably connected to the support frame 703 . A V-shaped groove, a C-shaped groove, or a U-shaped groove is provided on the outer circumference of the sheave.

[0042] Among them, the design of the V-groove, C-groove or U-groove wheel makes it easy to wrap the trailing edge of the wind turbine blade during use, which plays a role in limiting the planned movement; at the same time, when cooperating with the moving device and the fixing device for positioning, a lateral clamping force can be applied. When the intelligent maintenance platform moves on the blade surface of the wind turbine blade, the docking guide device ensures movement along the trailing edge and can monitor the change in the lateral clamping force when the curvature of the trailing edge changes; in particular, the design of the laser ranging sensor can provide real-time feedback on the change in the distance between the side of the intelligent maintenance platform and the side of the trailing edge. When the distance becomes larger, it means that the intelligent maintenance platform may separate from the blade when continuing to move in the current direction. At the same time, when the distance becomes smaller, the lateral clamping force is large, which will cause the moving device to require a greater driving force.

[0043] like Figure 1-2As shown, the clamping drive device is symmetrically arranged in two groups, including a drive motor 10, a gearbox 11, and a lifting drive rod 12. The drive motor 10 and gearbox 11 are connected in a transmission manner and mounted at one end of the mounting frame 13. The lifting drive rod 12 is connected to the output shaft of the gearbox 11 and is rotatably connected within the mounting frame 13, arranged perpendicular to the wind turbine blades. The lifting drive rod 12 is threadedly connected to the first clamping platform 5 and the second clamping platform 6, driving both of them to move linearly. During lifting and adjusting operation, the drive motor 10 and gearbox 11 start and output rotational operation, synchronously driving the lifting drive rod 12 connected to the output shaft of the gearbox 11 to rotate. The threaded connection then converts the rotational motion into lifting and linear movement.

[0044] Specifically, the clamping drive device includes a lifting drive rod 12 for linear motion and a locking function. When the intelligent maintenance platform of the present invention is clamped on the fan blade 16, the drive motor 10 is started, and the first clamping platform 5 and the second clamping platform 6 begin to move toward the fan blade. When the vertical clamping force generated between the intelligent maintenance platform and the fan blade reaches a preset value, the drive motor stops and locks the position; when the preset value is reached, the position is stopped and locked. If the clamping force is too large, the position is adjusted appropriately to maintain a stable state; the specific size of the clamping force is obtained by real-time monitoring through the first pressure sensor 504 installed on the cantilever 501.

[0045] Specifically, such as Figure 5-7 As shown, the first clamping platform 5 and the second clamping platform 6 are symmetrically arranged and have the same structure, including a cantilever 501, a moving block 502 and a side connecting plate 503 connected together. One end of the cantilever 501 is threadedly connected to the lifting drive rod 12 through the moving block 502. The two sides of the cantilever 501 are fixedly connected to two symmetrically distributed side connecting plates 503. Multiple sets of the fixing devices 8 and the moving devices 9 are all installed on the side connecting plates 503. Specifically, the cantilever 501 is provided with a first pressure sensor 504 for vertical pressure monitoring. The first pressure sensor 504 is preferably installed at the force center point of the cantilever 501, such as the midpoint of the center line connecting the two fixing seats 902, or at the intersection of the four fixing devices 8; specifically, it can be installed in the connection seam between the side connecting plate 503 and the cantilever 501, or in the mounting groove of the fixed end of the robot arm 15 reserved in the cantilever 501. The first pressure sensor 504 can monitor the stress of the entire clamping platform. When either the fixing device 8 or the moving device 9 contacts the fan blade, vertical pressure is generated, which is obtained through the first pressure sensor 504 and further transmitted to the controller.

[0046] Specifically, the fixing device 8 is provided with four groups and is installed at the corners of the side connecting plate 503. The fixing device 8 includes a suction cup 801 and a second spring 802. The suction cup 801 is connected to the side connecting plate 503 through the second spring 802. A second pressure sensor 803 for pressure monitoring is provided at the connection between the second spring 802 and the side connecting plate 503. The second pressure sensor 803 can feedback the clamping force to a certain extent.

[0047] like Figure 6-7 As shown, the moving device 9 is provided with two groups and is symmetrically mounted on the large surface of the side connecting plate 503. The moving device 9 includes two moving wheels 901 and a fixed seat 902. The moving wheels 901 are hinged on both sides of the fixed seat 902 through spring dampers 906 and a connecting rod group 903 distributed up and down. The inner side of the moving wheel 901 is connected to a moving wheel motor 905 for driving.

[0048] The fixing base 902 is provided with a monitoring camera 904 for observing the real-time status of the wind turbine blades. There are multiple monitoring cameras 904 , which are located on the side of the fixing base 902 directly facing the wind turbine blades.

[0049] In a specific embodiment, the first clamping platform 5 and the second clamping platform 6 serve as the main positioning and supporting components, and are symmetrically distributed up and down. Two groups of moving devices 9 are installed on the opposite side, that is, the working surface. The two groups of moving devices 9 are distributed side by side to form a four-wheel moving device; the four-wheel moving device is driven by a moving wheel motor 905 to realize forward, backward, turning and other functions; at the same time, the real-time situation on the wind turbine blades can be observed through four cameras.

[0050] The fixing devices 8 at the four corners are connected to the first clamping platform 5 and the second clamping platform 6 to form an elastic suspension device, which can better adapt to the curvature changes of the windward and leeward sides of the fan blades. Specifically, the fixing device is summarized as eight suction cups, four on the upper and lower platforms, and has two main functions: one is to compensate for the clamping force during movement with low negative pressure, and the other is to fix it with high negative pressure. Under high negative pressure, the suction cup provides adsorption force with the fan blade, and the suction cup and the fan blade achieve a strong fixation effect, and then the suction cup is locked; the limit block of the docking guide device 7 can both guide and meet the requirements of horizontal and vertical bidirectional clamping force.

[0051] It also includes an intelligent and automatically operating controller. The driving parts in all devices, such as the power parts in the robotic arm, the driving motor 10 for lifting, the moving wheel motor 905 and the pressure sensor, are electrically connected to the controller to realize data collection and the issuance of action instructions. This realization is achieved by relying on the existing computer program language and the equipment of the present invention.

[0052] like Figure 8-10 As shown, the use process of the present invention is as follows:

[0053] Specifically, the intelligent maintenance platform can operate automatically through pre-written tasks on the ground, or it can adopt manual operation mode.

[0054] First, the aircraft is flown to the designated position of the wind turbine blade 16 after the aircraft carries the mounting bracket 1 on the mounting platform.

[0055] Secondly, positioning after reaching the position: the docking guide device 7, the clamping drive device, and the fixing device 8 cooperate with each other to adjust the horizontal and vertical bidirectional clamping force in real time. During the clamping and positioning process, the blade curvature changes are monitored based on multiple sensors to ensure movement stability;

[0056] Then, after arriving at the work point, it is doubly fixed by the vacuum suction cup 801 and the clamping drive device, and the windward and leeward side maintenance operations are carried out simultaneously using the double working surface design.

[0057] Afterwards, when the mission is completed, the platform is released from its fixed state, the carrying bracket 1 is deployed to automatically dock with the aircraft, and finally returns safely to the recovery point.

[0058] The entire process above adopts intelligent adaptive control technology, which has the capabilities of autonomous positioning, dynamic clamping adjustment and parallel operation, realizing the automated and efficient operation of wind turbine blade maintenance.

[0059] like Figure 8 As shown, the specific steps include:

[0060] Step 1: During the flight, the suction cup does not initially touch the fan blades.

[0061] Step 2: docking to the trailing edge of the blade. After reaching the designated position, the docking guide device 7 works so that the limit block 701 abuts against the trailing edge of the fan blade 16;

[0062] Step 3: Clamping operation: the clamping drive device is activated to drive the two clamps closer to each other until the suction cups completely abut against the upper and lower surfaces of the fan blade 16;

[0063] Step 4: Sliding maintenance, maintaining a certain clamping force, and driving the intelligent maintenance platform to slide to the designated position through the moving device 9.

[0064] Step 5: After the maintenance task is completed, the drone automatically recovers the platform, significantly reducing operational risks and labor costs, and greatly improving the intelligence level and practical application value of wind turbine blade maintenance operations.

[0065] like Figure 10As shown, for large or complex tasks, multiple platforms can be combined to work together, expanding the scope of operation and improving work efficiency and safety. During collaborative operation, the positioning or relative movement of different equipment units is achieved through the cooperation of wire ropes and bidirectional winches 2.
