[0002] Wind turbine blades are the core devices of wind power generation equipment. Wind turbine blades are mainly composed of epoxy resin, composite skins, and coatings. Wind power generation equipment is used in outdoor environments, and the outdoor environment has a huge impact on wind turbine blades. This makes it necessary to inspect wind turbine blades at regular intervals. Wind turbine blades often have damaged surface coatings due to environmental problems. The designed curvature and angle of wind turbine blades are the best in aerodynamics. After the paint surface of the wind turbine blade is damaged, the resistance received by the wind turbine blade will increase, and the dynamic balance between wind turbine blades will be broken, and in severe cases, the blade will break. This makes it necessary to repair the damaged paint surface in time. At present, the repair method is often carried out manually. Manual repair is cumbersome, the quality cannot be controlled, and voids are easily generated inside the repair surface. Due to tool limitations, the repair surface often does not have the original curvature, and a repair surface without curvature will affect the wind power utilization effect of the entire leading and trailing edges of the wind turbine blade. Therefore, a repair tool for applying putty to the leading and trailing edges of wind turbine blades is proposed. Summary of the Invention

[0046] Material suction channels are opened on the material suction blocking strips 11. The material suction channels are connected to the material suction box 8 through material suction pipes 12. The extrusion piston 28 moves upward to generate suction force. The suction force acts on the material suction box 8 through the main pipeline 31 and the return pipeline 33, enabling the material suction holes provided on the material suction blocking strips 11 to recycle the excess putty, and being transported into the material suction box 8 through the material suction pipes 12.

The linkage member includes a triangular contact block 41 fixedly connected to the scraping plate 14. A triangular pressure-receiving block 42 adapted to the triangular contact block 41 is arranged on the back of the connecting block 40.

[0048] The arc repair assembly includes a U-shaped bracket 16 connected to the traction block 6. An adjustment disk 18 is connected to the U-shaped bracket 16 through a support shaft 17. An adjustment rotating disk 20 is connected to the adjustment disk 18 through a control shaft 19. An arc-shaped adjustable scraping plate 21 is connected to the adjustment rotating disk 20 through a rod connecting member. Further, the rod connecting member includes a connecting rod 43 rotatably connected to the adjustment rotating disk 20. The end of the connecting rod 43 is rotatably connected to an adjusting rod 44 penetrating through the side wall of the adjustment disk 18.

An adjustable knob 47 threadedly connected to the threaded adjustment column 45 is rotatably arranged at the end of the adjustment cylinder 46.

[0049] It should be noted that: the arc-adjustable scraping plate 21 is made of flexible metal. A plurality of arc-adjustable scraping plates 21 distributed on the adjustment rotating disk 20 have arcs in different interval arcs. During use, first select the arc-adjustable scraping plate 21 within a suitable angle interval, and then adjust the angle of the arc-adjustable scraping plate 21 through the adjustable knob 47 to meet the plastic repair use of multiple arcs.

[0051] When the present invention repairs and processes a wind power blade in use, the device is carried to the position of the wind power blade that needs to be repaired. At this time, the L-shaped combined plate 2 is unfolded, and the suction cup 24 arranged thereon is used to fix the device at the repair position. At this time, the control driving motor 4 drives the traction column 5 to rotate, and the traction block 6 connected to the feeding assembly is connected with the traction column 5. After the connection, the putty is automatically fed. During the feeding process, the traction block 6 drives the material storage box 9 to move, the material storage box 9 drives the material suction box 8 connected thereto to move, the limit wheel 36 arranged on the material storage box 9 meshes with the driving rack 37 during the movement, and the rotating shaft is driven to rotate during the movement. The internal transmission gear 34 connected to the rotating shaft drives the vertical rack 35 to move, and the connection cover 30 connected to the vertical rack 35 makes the extrusion column 29 drive the extrusion piston 28 to squeeze the liquid stored in the material storage box 9 downward. The paint putty is extruded out of the material extrusion pipe 32 to achieve discharging, and is initially scraped flat at the repair place under the action of the serrated plastic strips 10, achieving the effect of automatic feeding;

[0052] At this time, the traction block 6 connected to the repair component is threadedly connected to the traction column 5. At this moment, it will drive the repair component to move. During the movement of the repair component, the vibrators 7 arranged on both sides will continuously vibrate the putty. Under the action of the vibration force, the flexible scraping rubber strip 15 at the bottom of the scraping plate 14 arranged on the adapter block 13 will scrape off the excess putty at the arc repair area during the movement. The scraped putty will move forward along with the scraping plate 14. The continuous movement of the repair component will contact the feeding component. During this process, the triangular pressure block 42 will squeeze the triangular contact block 41, and then the connecting block 40 connected to the triangular pressure block 42 will drive the suction material blocking strip 11 to move downward. The suction material blocking strip 11 will block the shaping strip 10. During this process, the excess putty will be in the area between the scraping plate 14 and the shaping strip 10. At this time, control the traction block 6 connected to the feeding component and the repair component to move and contact the threaded aggregate section on the traction column 5. At this time, under the action of the traction column 5, it will drive the feeding component and the repair component to move. During the movement, the other driving rack 37 arranged in the reverse direction will be engaged, and then the extrusion piston 28 will move upward to generate suction. The suction will act on the suction material box 8 through the main pipeline 31 and the return pipeline 33, and the suction holes arranged on the suction material blocking strip 11 will recover the excess putty.

[0053] During the feeding process, other operations can be carried out simultaneously. According to the angle of the wind power blade at the actual processing location, select the arc adjustable scraping plate 21 within the suitable arc range by rotating the support shaft 17, and adjust the angle of the arc adjustable scraping plate 21 through the control shaft 19 and the adjustable knob 47 arranged on the support shaft 17 to make it consistent with the arc of the wind power blade at the repair location. After it is consistent with the predetermined angle, drive the arc adjustable scraping plate 21 to move through the traction block 6 to correct the angle of the leveled putty repair surface and ensure that the repaired angle can meet the use effect of the wind power blade.
