Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade damage detection technology, specifically a wind turbine blade damage detection device. Background Technology

[0002] Wind turbine blades are the most basic and critical components of wind turbines. After the wind turbine blades are manufactured, it is necessary to inspect the surface damage of the entire wind turbine blade.

[0003] Currently, among the existing technologies, Chinese patent with publication number CN213275382U discloses an online detection device for wind turbine blade damage. This device sets the detection window as a magnifying glass structure, which allows observation of the placed wind turbine blades through the detection window, thereby enabling direct identification of the damage to the wind turbine blades.

[0004] However, in actual use, after one side of the wind turbine blade is inspected, the other side of the wind turbine blade also needs to be inspected. Therefore, the wind turbine blade needs to be flipped. However, the wind turbine blade is large and heavy, making it difficult to flip. In view of this, a wind turbine blade damage detection device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a wind turbine blade damage detection device that can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention proposes a wind turbine blade damage detection device, comprising a base, on which a support device and a detection mechanism for detecting damage to wind turbine blades are mounted. The base has locking teeth on both sides, and the detection mechanism includes:

[0007] A U-shaped frame, wherein a connecting plate is fixedly connected to the surface of the U-shaped frame, and a vision inspection machine is installed on both the U-shaped frame and the connecting plate;

[0008] Mounting plate, the mounting plate is fixedly mounted on the U-shaped frame, and the mounting plate is rotatably connected to the support wheels;

[0009] Stepper motor one, the stepper motor one is fixedly mounted on the outer wall of the U-shaped frame, the output shaft of the stepper motor one is fixedly connected to a rotating shaft, and a gear is fixedly connected to the rotating shaft.

[0010] Preferably, the inner surface of the U-shaped frame is in contact with the outer wall of the base, and the support wheel abuts against the base.

[0011] Preferably, the stepper motor, the rotating shaft, and the gear are all provided in two sets, and the two sets of stepper motors, rotating shafts, and gears are symmetrically arranged with the center line of the base as the axis of symmetry. The gears mesh with the locking teeth, and the output shaft of the stepper motor drives the gears to rotate. Under the meshing action of the locking teeth, the U-shaped frame can move. During the movement, the upper and lower sets of vision inspection machines perform visual inspection on the upper and lower sides of the wind turbine blades to detect damage to the blade surface.

[0012] Preferably, the upper side of the base has a notch.

[0013] Preferably, the support device includes a second stepper motor, a bidirectional screw fixedly connected to the output shaft of the second stepper motor, a threaded seat threadedly connected to the bidirectional screw, a support column fixedly connected to the threaded seat, and a support plate fixedly connected to the top of the support column. The second stepper motor drives the bidirectional screw to rotate, allowing the threaded seat to move and thereby adjust the position of the support plate. This allows the support plate to adapt to blades of different sizes, supporting the blades and facilitating subsequent damage detection of the blades.

[0014] Preferably, the second stepper motor is fixedly mounted on the outer wall of the base, the bidirectional screw is rotatably connected in the recess, a guide rod is fixedly connected in the recess, and the guide rod passes through the threaded seat and is slidably connected to the threaded seat.

[0015] Preferably, the height of the support plate is located between the two sets of vision inspection machines.

[0016] This invention provides a wind turbine blade damage detection device. It has the following advantages:

[0017] (1) The wind turbine blade damage detection equipment uses a stepper motor to drive the gear to rotate. The gear meshes with the teeth on both sides of the base, causing the U-shaped frame to move. During the movement, the two sets of visual inspection machines can visually inspect the upper and lower sides of the wind turbine blade. The blade surface damage can be detected without flipping the blade, which solves the problem of difficulty in flipping the blade due to its large size and weight.

[0018] (2) The wind turbine blade damage detection equipment uses a support device, and the stepper motor drives the bidirectional screw to rotate, so that the threaded seat moves and adjusts the position of the support plate. The guide rod in the notch ensures the stability of the threaded seat movement. This design allows the support plate to adapt to blades of different sizes, support the blades, and facilitate subsequent damage detection of the blades. Attached Figure Description

[0028] Please see Figures 1-4 This utility model proposes a wind turbine blade damage detection device, including a base 1, a support device 2 and a detection mechanism 3 for detecting damage to wind turbine blades on the base 1, and locking teeth 4 on both sides of the base 1.

[0029] In this embodiment of the invention, in order to support wind turbine blades of different sizes and facilitate subsequent inspection of the wind turbine blades, specifically, a notch 101 is provided on the upper side of the base 1. The support device 2 includes a second stepper motor 21, a bidirectional screw 22 is fixedly connected to the output shaft of the second stepper motor 21, a threaded seat 24 is threadedly connected to the bidirectional screw 22, a support column 25 is fixedly connected to the threaded seat 24, and a support plate 26 is fixedly connected to the top of the support column 25. The second stepper motor 21 is fixedly installed on the outer wall of the base 1. The bidirectional screw 22 is rotatably connected in the notch 101, and a guide rod 23 is fixedly connected in the notch 101. The guide rod 23 passes through the threaded seat 24 and is slidably connected to the threaded seat 24. The second stepper motor 21 drives the bidirectional screw 22 to rotate, and under the limiting action of the guide rod 23, the threaded seat 24 moves, thereby adjusting the position of the support plate 26. This design allows the support plate 26 to adapt to blades of different sizes, supporting the blades and facilitating subsequent damage inspection of the blades.

[0030] Furthermore, to facilitate damage detection of wind turbine blades, the detection mechanism 3 specifically includes a U-shaped frame 31, a mounting plate 34, and a stepper motor 36. A connecting plate 32 is fixedly connected to the surface of the U-shaped frame 31. Vision inspection machines 33 are mounted on both the U-shaped frame 31 and the connecting plate 32. The vision inspection machine 33 mainly consists of a camera, an optical lens, an image acquisition card, and a vision system; this is existing technology and will not be described in detail here. The support plate 26 is positioned between the two sets of vision inspection machines 33. The mounting plate 34 is fixedly mounted on the U-shaped frame 31, and a support wheel 35 is rotatably connected to the mounting plate 34. The inner surface of the U-shaped frame 31 is in contact with the outer wall of the base 1, and the support wheel 35 abuts against the base 1. The stepper motor 36 is fixedly mounted on the outer wall of the U-shaped frame 31. A rotating shaft 37 is fixedly connected to the output shaft of stepper motor 36, and a gear 38 is fixedly connected to the rotating shaft 37. There are two sets of stepper motor 36, rotating shaft 37 and gear 38, and the two sets of stepper motor 36, rotating shaft 37 and gear 38 are symmetrically arranged with the center line of base 1 as the axis of symmetry. The gear 38 meshes with the locking teeth 4. The output shaft of stepper motor 36 drives the rotating shaft 37 to rotate, which in turn drives the gear 38 to rotate. Under the meshing action of locking teeth 4, the U-shaped frame 31 can move. The setting of support wheel 35 ensures the stable movement of U-shaped frame 31. During the movement of U-shaped frame 31, the upper and lower sets of vision inspection machines 33 perform visual inspection on the upper and lower sides of the wind turbine blade to detect damage on the blade surface, which solves the problem of difficulty in flipping due to the large size and weight of the blade.

During the movement of U-shaped frame 31, the upper and lower sets of vision inspection machines 33 perform visual inspection on the upper and lower sides of wind turbine blades to complete the detection of surface damage on the blades.
