[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0026] Example

[0027] like Figure 1-4 As shown, an embodiment of the present invention provides a wind turbine blade detection device, comprising a mounting base 1;

[0028] The mounting base 1 is provided with a connection hole and is connected to the UAV frame by bolts, providing an installation basis for the entire detection device, and a horizontal rotation device 2 is fixedly connected below it.

[0029] Achieving stable installation of the detection device on the drone, so that the detection device can follow the drone to the inspection position of the wind turbine blade, is the key connecting component for the collaborative work of the entire detection device and the drone.

[0030] The horizontal rotation device 2 includes a housing 21 , a rotation motor 22 is fixedly connected to the center of the housing 21 , an output end of the rotation motor 22 is connected to a rotation disk 23 , and a bottom of the rotation disk 23 is connected to the vertical rotation device 3 .

[0031] The rotating motor 22 drives the rotating disk 23 to rotate, thereby realizing the horizontal rotation of the vertical rotating device 3 and the laser emitter 4. It can adjust the detection angle of the detection device in the horizontal direction, expand the detection range of the blade, and ensure that the laser emitter 4 can scan and detect the blade from different horizontal directions.

[0032] The vertical rotation device 3 consists of two symmetrical outer covers 31. A base 32 is installed on the inner wall of the outer cover 31, and a servo motor 33 is fixedly connected inside. The output end of the servo motor 33 is connected to a worm 34, which is engaged with a worm gear 35 for transmission. The worm gear 35 is rotatably connected to the base 32. A rotating rod 36 is connected at the center of the worm gear 35, and one end of the rotating rod 36 is connected to the laser emitter 4.

[0033] Servo motor 33 drives worm 34, which in turn rotates worm gear 35 and rotating rod 36, thereby rotating laser emitter 4 vertically. This, in conjunction with horizontal rotation device 2, allows laser emitter 4 to flexibly adjust its detection angle, enabling comprehensive inspection of the blade from all directions. For example, when inspecting the edge of a blade, vertical rotation device 3 can be used to adjust laser emitter 4 to the appropriate elevation or depression angle for inspection.

[0034] The laser emitter 4 is fixedly connected to one end of the rotating rod 36 and is connected to the vertical rotating device 3 through the rotating rod 36. The emission direction can be adjusted under the action of horizontal and vertical rotation.

[0035] Laser beams are emitted to inspect wind turbine blades. Information on the blade surface and internal structure is obtained through the principle of laser reflection. For example, it can detect whether the blades have defects such as cracks and deformations. It is a key component for detecting blade conditions.

[0036] The battery box 5 is located at the bottom of the vertical rotating device 3, and is internally connected to a processor and a wireless signal communication module to provide power support for the entire detection device.

[0037] The battery pack 5 provides power to components such as the rotary motor 22, servo motor 33, laser transmitter 4, processor, and wireless signal communication module to ensure the normal operation of the detection device. Meanwhile, the processor in the battery pack 5 processes the detection data, and the wireless signal communication module transmits the data to the control center for transmission and processing.

[0038] The transmission structure of the worm 34 and the worm wheel 35 is as follows: the worm 34 is rotatably connected to the base 32 through a bearing seat, meshing with the worm wheel 35 for transmission, and the servo motor 33 drives the worm 34 to rotate.

[0039] This transmission structure has a large transmission ratio, which can convert the high-speed rotation of the servo motor 33 into the low-speed, high-torque rotation of the worm gear 35, thereby smoothly driving the rotating rod 36 and the laser emitter 4 to rotate in the vertical direction, achieving precise angle adjustment. Once the laser emitter 4 is adjusted to the desired angle, it can remain stable and is not easily changed by external forces.

[0040] When the wind turbine blade inspection device is in operation, the mounting base 1 securely mounts the entire device on the drone frame, and the drone carries the device near the wind turbine blades. Under command from the control center, the rotary motor 22 in the horizontal rotation device 2 is activated, driving the rotary disk 23 to rotate, thereby adjusting the horizontal angle of the vertical rotation device 3 and the laser emitter 4. Simultaneously, the servo motor 33 in the vertical rotation device 3 drives the worm 34. The meshing transmission between the worm 34 and the worm gear 35 drives the worm gear 35 and its connected rotating rod 36, achieving vertical angle adjustment of the laser emitter 4. The laser emitter 4 emits a laser beam to inspect the blades. The detection data is transmitted to a processor in the battery compartment 5, which processes the data and then sends it to the control center via a wireless signal communication module, such as a 4G / 5G communication module. Based on the data, operators can determine the blade condition, such as whether there are defects such as cracks or deformation, thereby achieving comprehensive and efficient inspection of wind turbine blades.

[0041] like Figure 3 As shown, in some embodiments, the worm 34 is rotatably connected to the base 32 via a bearing seat; the bearing seat provides a stable support point for the worm 34 , so that the worm 34 can rotate smoothly under the drive of the servo motor 33 .

[0042] like Figure 3 As shown, in some embodiments, the rotary motor 22 and servo motor 33 are both forward and reverse motors. The installation angle and orientation of the blades may vary in different wind farm environments. The forward and reverse motors enable the detection device to flexibly adjust the angle of the laser emitter 4 based on actual conditions, adapting to blade detection in various installation positions and allowing rotation within a certain angle range.

[0043] like Figure 1 As shown, in some embodiments, the processor is connected to a storage module, which is located in the battery compartment 5 and is used to store data generated during the detection process. In areas with high signal interference around the wind farm, data transmission may be temporarily interrupted. In this case, the storage module can temporarily save the detection data to prevent data loss. The storage module also serves as a data backup. Even if errors occur or partial data is lost during data transmission, the complete data can be retrieved from the storage module for transmission, ensuring data integrity and reliability.

[0044] In some embodiments, the wireless signal communication module is a 4G / 5G communication module; after the laser transmitter 4 detects the wind turbine blades, the processor encodes and modulates the collected blade structure data and transmits it through the antenna of the 4G / 5G communication module. After receiving the signal, the base station transmits it to the control center for analysis.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
