[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0031] Please refer to Figures 1-8 The embodiment of the utility model provides a wind turbine hybrid tower inspection drone, including a body 1, a fixing plate 6 is installed at the lower end of the body 1 by bolts, the lower end of the fixing plate 6 is ring-shaped, and connecting rods 7 are provided on both sides of the fixing plate 6, the lower end of the connecting rod 7 is connected to the annular sleeve 8, and a detection mechanism is rotatably installed in the annular sleeve 8.

[0032] Among them, the detection mechanism includes a gear ring 11 located in the annular sleeve 8, and a swivel 12 is provided on the outside of the gear ring 11. The swivel 12 is rotatably set in a rotation groove 18 opened on the inner side of the annular sleeve 8. The gear ring 11 rotates stably through the rotation groove 18, and a driving wheel 17 is rotatably set on the lower side of the annular sleeve 8. The driving wheel 17 is engaged with the gear ring 11. The driving wheel 17 is driven by the motor to make the gear ring 11 rotate automatically.

[0033] Since a plurality of ferrules 13 are provided at the upper end of the gear ring 11 and an infrared sensor 14 is installed in the ferrule 13, when the gear ring 11 rotates, the plurality of infrared sensors 14 are prompted to rotate for inspection. The rotating design eliminates blind spots in detection, ensures that each part can be carefully inspected, improves the reliability of detection, and can effectively identify the position of the tower with defects through inspection.

[0034] In addition, a socket 15 is symmetrically provided on the upper side of the ferrule 13 , and a positioning buckle 16 is inserted into the socket 15 . The positioning buckle 16 is used to fix the infrared sensor 14 and also facilitates its assembly and disassembly.

[0035] Furthermore, in order to prevent the infrared sensor 14 from being hit during inspection, a protection mechanism is installed on the outside of the annular sleeve 8 to protect the detection mechanism.

[0036] Specifically, the protective mechanism includes an airbag cover 19 that is sleeved on the outside of the annular cover 8. A pair of slides arranged on the inside of the airbag cover 19 are slidably connected to the mounting grooves 9 opened on both sides of the annular cover 8. The airbag cover 19 protrudes from the annular cover 8. When the device is hit by a collision, the airbag cover 19 contacts the collision object first, cushions the force of the collision, and protects the infrared sensor 14.

[0037] In addition, a screw rod 10 is rotatably arranged in the mounting groove 9. The screw rod 10 is threadedly connected to the slide plate in the airbag cover 19. The screw rod 10 is driven by a motor. When the screw rod 10 rotates, the airbag cover 19 is automatically moved. When the airbag cover 19 moves to the upper end of the mounting groove 9, the airbag cover 19 wraps the infrared sensor 14, which can effectively prevent the infrared sensor 14 from being hit by foreign objects on the ground when the body 1 descends.

[0038] A groove 21 is provided on the outer side of the airbag cover 19 , and one of the connecting rods 7 is located in the groove 21 , so that the airbag cover 19 can move smoothly.

[0039] Furthermore, a ring-shaped air bag 20 is provided at the bottom of the annular sleeve 8 to enhance the protection of the infrared sensor 14 .

[0040] It is worth noting that a pair of brackets 2 are provided at the lower end of the body 1, and a pad is provided at the lower end of the bracket 2. A through hole 3 is opened on the lower side of the pad, and a buffer rod 5 is slidably provided in the through hole 3. The buffer rod 5 is connected to the inner wall of the through hole 3 by a spring 4. When the body 1 falls, the buffer rod 5 contacts the ground and squeezes the spring 4. The elastic action of the spring 4 cushions the body 1, thereby strengthening the protection of the infrared sensor 14.

[0041] In summary, the working principle of a wind turbine hybrid tower inspection drone in an embodiment of the present invention is as follows: during inspection, the gear ring 11 rotates with the infrared sensor 14 through the engagement of the driving wheel 17 and the gear ring 11, thereby achieving all-round coverage of the inner and outer surfaces of the tower, and the airbag cover 19 located on the outside of the annular cover 8 is used to protect the infrared sensor 14. When the body 1 is collided, the protruding airbag cover 19 is used to buffer the force of the collision to prevent the infrared sensor 14 from being hit during inspection; secondly, the airbag cover 19 slides in the mounting groove 9, so that the airbag cover 19 slides upward to protect the infrared sensor 14, thereby preventing the infrared sensor 14 from being hit by foreign objects on the ground when the body 1 descends.

[0042] The above is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
