[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] A drone-based wind turbine inspection device, such as Figures 1 to 9 As shown, the device includes a drone body 1. A winding assembly for winding the collection tape 37 is installed on the bottom outer wall of the drone body 1. A vertical plate 15 is fixed to the bottom of the drone body 1 by bolts. An electric telescopic rod 14 is fixed to one side of the outer wall of the vertical plate 15 by screws. An annular cutter 27 is fixed to the output end of the electric telescopic rod 14 by pins. A T-shaped rod 29 is fixed to one side of the outer wall of the annular cutter 27 by screws. A rectangular plate 31 is slidably connected to the outer wall of the T-shaped rod 29. A contact frame 28 adapted to the outer diameter of the annular cutter 27 is welded to the bottom of the rectangular plate 31. A spring 30 is sleeved on the outer wall of the T-shaped rod 29. The two ends of the spring 30 are respectively fixed to the inner wall of one side of the T-shaped rod 29 and the outer wall of one side of the rectangular plate 31.

[0035] When the wind turbine needs to be inspected, the unmanned aerial vehicle body 1 takes off when the blades of the wind turbine are in a stationary state, and the collection tape 37 is unwound by using the winding assembly when the unmanned aerial vehicle body 1 moves to the blades. The electric telescopic rod 14 is controlled in a remote control mode to drive the annular cutter 27 to move horizontally, and the annular cutter 27 drives the abutting frame 28 to move in the process of horizontal movement. The non-adhesive surface of the collection tape 37 is pushed in the process of movement of the abutting frame 28. After the collection tape 37 is pushed, the adhesive surface thereof is adhered to the surface of the blade. The collection tape 37 is driven to move away from the blade after the adhesive surface thereof is adhered. At this time, the adhesive surface of the collection tape 37 is torn off from the blade. At this time, the coating particles on the blade are attached to the collection tape 37. The collection tape 37 is used to collect the coating particles. The coating particles are detected to analyze the performance such as corrosion resistance, so as to determine whether the coating particles are invalid.

[0036] The winding assembly comprises L-shaped plates 9, threaded seats one 10 and two 35. The two L-shaped plates 9 are fixed to the bottom outer wall of the unmanned aerial vehicle body 1 by screws. The threaded seats one 10 and two 35 are respectively rotationally connected to the bottoms of the two L-shaped plates 9. One of the bottoms of the two L-shaped plates 9 is fixedly connected with the bottom of the threaded seat one 10. The other one is provided with a winding spring 38 between the bottom of the other L-shaped plate 9 and the threaded seat two 35. The threaded seat two 35 is sleeved with a winding drum one 36. The threaded seat one 10 is sleeved with a winding drum two 39. The collection tape 37 is wound between the winding drum one 36 and the winding drum two 39. The threaded seat two 35 and the threaded seat one 10 are respectively provided with the cover plates 4.

[0037] The winding drum one 36 is provided to wind the collection tape 37. A certain length of the collection tape 37 is pulled along the winding drum one 36 before inspection, and the end of the collection tape 37 is adhered to the winding drum two 39. The threaded seat two 35 and the threaded seat one 10 can be respectively sleeved with the winding drum one 36 and the winding drum two 39. The two cover plates 4 are respectively threadedly connected with the threaded seat one 10 and the threaded seat two 35, so as to fix the winding drum one 36 and the winding drum two 39, to avoid slipping in the process of rotation. The winding drum two 39 is driven to rotate by the winding motor 12 to wind the collection tape 37. The winding spring 38 can ensure that the collection tape 37 is in a tension state in the process of winding. When the collection tape 37 needs to be adhered to the blades of the wind turbine, the output end of the winding motor 12 is self-locked to avoid rotation of the threaded seat one 10. When the electric telescopic rod one 14 drives the abutting frame 28 to push the collection tape 37 between the winding drum one 36 and the winding drum two 39 horizontally, the winding drum one 36 unwinds a certain length of the collection tape 37 on the basis of the original length, so as to ensure that the adhesive surface of the collection tape 37 is attached to the surface of the blades of the wind turbine to collect the coating particles.

[0038] The bottom of the unmanned aerial vehicle body 1 is provided with a sample collection assembly, which comprises a bottom plate 13 and a side plate 17, the bottom plate 13 is fixed to the bottom of the unmanned aerial vehicle body 1 through the side plate 17, a limiting sliding groove is formed in the surface of the bottom plate 13, a sliding block 26 is slidably connected to the limiting sliding groove, a spring 25 is arranged between the outer wall of one side of the sliding block 26 and the sliding groove, a baffle 16 is fixed to the top of the two sliding blocks 26, a limiting plate 21 is welded to the top of the bottom plate 13, a plurality of groups of stacked collection plates 19 are arranged between the baffle 16 and the limiting plate 21, a clamping groove 18 is formed in the surface of the collection plate 19, and an adsorption groove 11 is formed in the bottom and top of the collection plate 19, and a jacking mechanism for jacking the collection plate 19 is arranged on the outer wall of one side of the bottom plate 13.

[0039] In order to facilitate the collection of the collected coating particles, when the unmanned aerial vehicle body 1 drives the collection tape 37 to separate from the blade of the wind turbine, at this time, the jacking mechanism is used to jack one of the collection plates 19 located above, and the plurality of collection plates 19 are limited in the front, rear, left and right directions by the baffle 16, the side plate 17 and the limiting plate 21, so as to effectively ensure the stability of the collection plate 19. When the jacking mechanism jacks the collection plate 19, the collection tape 37 between the winding drum 36 and the winding drum 39 is kept in a relative state with the collection plate 19, at this time, the electric telescopic rod 14 is used to drive the annular cutter 27 and the abutting frame 28 to move horizontally again, the abutting frame 28 is first moved to abut the side surface of the collection plate 19, at this time, the collection tape 37 with coating particles attached is abutted with the side surface of the collection plate 19, and as the output end of the electric telescopic rod 14 continues to move, the annular cutter 27 is displaced relative to the abutting frame 28, and the spring 30 is gradually stretched in the process. One end of the annular cutter 27 is a blade structure, and the width of the annular cutter 27 is less than the width of the collection tape 37, so that when the annular cutter 27 moves into the clamping groove 18, the rectangular cutting of the collection tape 37 is realized, and the cut collection tape 37 is tightly abutted with the collection plate 19, which is convenient for subsequent analysis and detection.

[0040] At the same time, since the width of the annular cutter 27 is less than the width of the collection tape 37, the annular cutter 27 only cuts a rectangular structure on the collection tape 37, and the collection tape 37 will not be broken, and the winding assembly can still normally wind the collection tape 37, so that the collection of coating particles on different blades or different positions of the same blade is facilitated.

[0041] The jacking mechanism comprises an electric telescopic rod 23 and an extension plate 24, the extension plate 24 is welded to the outer wall of one side of the bottom plate 13, the electric telescopic rod 23 is fixed to the outer wall of the bottom of the extension plate 24, and the output end of the electric telescopic rod 23 is fixed with an electromagnet 22 through a screw.

[0042] The electromagnet 22 can be driven to move along the vertical direction by the electric telescopic rod 23, and the outer diameter of the electromagnet 22 is kept the same as the output end of the electric telescopic rod 23 after the electromagnet 22 moves into the adsorption groove 11 at the bottom of the collecting plate 19, and the electromagnet 22 is adsorbed and fixed to the adsorption groove 11 at the bottom of the collecting plate 19 when the electromagnet 22 is powered, so as to ensure the stability of the movement of the collecting plate 19 when the collecting plate 19 is jacked up.

[0044] When the adhesive tape 37 is cut and closely attached to the collecting plate 19, the collecting plate 19 is gradually moved into the storage box 6 by the electric telescopic rod 23, and when the adsorption groove 11 at the top of the collecting plate 19 and one of the magnets 32 on the plate conveyor belt 34 are attached to each other, the collecting plate 19 is adsorbed and fixed by the magnet 32, and when the electromagnet 22 is powered off, the output end of the electric telescopic rod 23 is reversely moved to reset, and the spring 25 is used to push the remaining collecting plates 19 by the baffle 16, so as to realize the progression of the collecting plate 19, and when the collecting plate 19 needs to be taken out of the storage box 6, the buckle 2 is unlocked from the flip cover 3, and the flip cover 3 is rotated along the storage box 6, so as to facilitate the taking out of the collecting plate 19, and the driving motor 7 can drive the plate conveyor belt 34 to move through the driving roller 33, so that the magnet 32 can move step by step to adsorb and fix different collecting plates 19.

[0045] The outer wall of one side of the unmanned aerial vehicle body 1 is provided with a camera 20;

[0046] The camera 20 is arranged to facilitate the unmanned aerial vehicle body 1 to take pictures in front during flight, so as to facilitate the operator to observe the picture in front of the unmanned aerial vehicle body 1.
