Description

Technical Field

[0001] This utility model relates to the field of drone inspection technology, and in particular to a fully automatic drone for inspecting wind power hybrid towers. Background Technology

[0002] Drone inspection is a technology that uses unmanned aerial vehicles for inspection and surveying. By carrying advanced equipment, it can achieve efficient and accurate inspection of ground facilities, environment and structure. This technology can provide a more convenient and economical solution for areas that are difficult to reach by manpower or where inspection costs are high. Drone inspection is often used for the inspection of wind turbine hybrid towers, which are a type of wind turbine support structure that combines concrete and steel structures.

[0003] In the existing technology, it is often necessary to use drones to inspect wind power towers. However, drones are usually equipped with a support structure for landing. During the flight, this support structure is always exposed to the outside, which increases the flight drag of the drone and affects the flight speed of the drone during inspection. Furthermore, after the inspection is completed, it is difficult for the drone to transport the tool kit for maintenance to the workers, resulting in poor functionality of the drone. Utility Model Content

[0004] This utility model provides a fully automatic inspection drone for wind power hybrid towers, which helps to reduce the resistance during normal drone flight and inspection, and facilitates the convenient transportation of the toolbox for post-inspection maintenance.

[0005] In order to solve the problems of the existing technology, this utility model discloses a fully automatic inspection drone for wind power hybrid towers, including a body, an infrared detector and a camera, wherein the infrared detector and the camera are both installed at the front end of the body;

[0006] The lower end of the machine body has storage slots on both sides. A guide shaft is fixed in each storage slot. A lifting plate is slidably sleeved around the guide shaft. A support plate extending downward out of the storage slot is fixed at the lower end of each lifting plate. A spring buffer rod is fixed at the lower end of each support plate. A buffer support plate is connected to the lower end of each spring buffer rod. A storage drive assembly is provided inside the machine body.

[0007] The inner side of each support plate has a groove, and a placement plate is hinged to the bottom of each groove. A shrinkage groove is opened in the middle of the lower end of the machine body, and an electric cylinder is fixed in the shrinkage groove. A pressure plate connected to the power end of the electric cylinder is provided below the machine body.

[0008] Furthermore, the storage drive assembly includes a forward and reverse motor, a drive gear, a transmission shaft, a driven gear, a main bevel gear, a lead screw, and a secondary bevel gear. The upper end of the body has a mounting cavity, the forward and reverse motor is fixed in the mounting cavity, and the drive gear is connected to the power end of the forward and reverse motor.

[0009] Furthermore, the drive shaft is located in the mounting cavity, and both the left and right ends of the drive shaft pass through the storage groove through the rotation of the machine body. There are two main bevel gears, each fixed to the left and right ends of the drive shaft.

[0010] Furthermore, the lead screw has two parts, each rotatably connected to one of the two storage slots. The lifting plate is threadedly connected to the lead screw. The auxiliary bevel gear has two parts, each fixedly sleeved on the upper end of the outer periphery of the two lead screws. The main bevel gear meshes with the adjacent auxiliary bevel gear.

[0011] Furthermore, each groove has a spring return rod fixed at its top end, and each spring return rod has a retaining ball connected to its lower end. Each shelf has a retaining groove at its upper end, and the retaining ball is engaged in the retaining groove.

[0012] Furthermore, a semi-circular pull ring is fixed to the upper end of the inner side of each shelf.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] 1. When the drone is used to inspect the wind power tower, the support plate and spring buffer rod can be easily stored in the storage slot by combining the operation of the storage drive component. This can reduce the flight resistance of the drone when inspecting the wind power tower and help to effectively ensure the speed of the drone during inspection flight.

[0015] 2. By unfolding the shelf and setting it at a 90-degree angle to the support plate, the tool box for inspection and maintenance is placed on the unfolded shelf. Then, the extension of the electric cylinder drives the pressure plate to press the tool box firmly on the shelf, which helps to prevent the tool box from falling off accidentally during transportation. Therefore, the tool box for inspection and maintenance can be conveniently transported to workers by drone, effectively improving the functionality of the drone. Attached Figure Description

[0024] A fully automated inspection drone for wind power towers:

[0025] like Figure 1-4 As shown, this embodiment includes a body 1, an infrared detector 2, and a camera 3. The infrared detector 2 and the camera 3 are both installed at the front end of the body 1. Storage slots 7 are opened on both sides of the lower end of the body 1. Guide shafts 9 are fixed inside each storage slot 7. Lifting plates 8 are slidably sleeved around each guide shaft 9. Support plates 4 extending downwards from the storage slots 7 are fixed to the lower ends of each lifting plate 8. Spring buffer rods 5 are fixed to the lower ends of each support plate 4. Buffer support plates 6 are connected to the lower ends of each spring buffer rod 5. A storage drive assembly is provided inside the body 1. The storage drive assembly includes a forward / reverse motor 12, a drive gear 14, a transmission shaft 13, a driven gear 15, a main bevel gear 16, and a lead screw. 10. Secondary bevel gear 17: The upper end of the machine body 1 has an installation cavity 11. The forward and reverse motor 12 is fixed in the installation cavity 11. The driving gear 14 is connected to the power end of the forward and reverse motor 12. The transmission shaft 13 is located in the installation cavity 11, and the left and right ends of the driving shaft 13 are rotated through the machine body 1 and enter the storage groove 7. There are two main bevel gears 16, which are fixed to the left and right ends of the transmission shaft 13. There are two lead screws 10, which are rotatably connected to the two storage grooves 7. The lifting plate 8 is threadedly connected to the lead screw 10. There are two secondary bevel gears 17, which are fixedly sleeved on the upper end of the outer periphery of the two lead screws 10. The main bevel gears 16 mesh with the adjacent secondary bevel gears 17.

[0026] When the drone conducts inspections of the wind turbine tower, the operation of the forward and reverse motors 12 drives the drive gear 14, driven gear 15, transmission shaft 13, main bevel gear 16, secondary bevel gear 17, and lead screw 10 to rotate. The lead screw 10 drives the lifting plate 8 to slide upward along the guide shaft 9. Therefore, the lifting plate 8 drives the support plate 4 and spring buffer rod 5 to be stored in the storage slot 7. When the drone flies and conducts safety inspections of the wind turbine tower through the infrared detector 2 and camera 3, the flight resistance of the drone during the inspection of the wind turbine tower can be reduced, which helps to effectively ensure the speed of the drone during the inspection flight.

[0027] like Figure 1-3 As shown, in this embodiment, the forward and reverse motor 12 is fixed in the mounting cavity 11, the drive gear 14 is connected to the power end of the forward and reverse motor 12, the transmission shaft 13 is located in the mounting cavity 11, and the left and right ends of the drive shaft 13 are rotatably inserted into the storage slot 7 through the body 1, the main bevel gear 16 is provided in two and is fixed to the left and right ends of the transmission shaft 13, the lead screw 10 is provided in two and is rotatably connected to the two storage slots 7, the lifting plate 8 is threadedly connected to the lead screw 10, the secondary bevel gear 17 is provided in two and is fixedly sleeved on the upper end of the outer periphery of the two lead screws 10, and the main bevel gear 16 meshes with the adjacent secondary bevel gear 17.

[0028] When the drone finishes its inspection and needs to land, the forward and reverse motors 12 drive the drive gear 14, driven gear 15, transmission shaft 13, main bevel gear 16, secondary bevel gear 17 and lead screw 10 to rotate. The lead screw 10 will drive the lifting plate 8 to slide down along the guide shaft 9. Therefore, the lifting plate 8 will drive the support plate 4 and spring buffer rod 5 to move down out of the storage slot 7. Then, it will contact the ground through the buffer support plate 6, and the spring buffer rod 5 will buffer the body 1, which is beneficial for the drone's landing protection.

[0029] like Figure 5-7 As shown, in this embodiment, the inner side of the support plate 4 is provided with grooves 18, and the bottom end of each groove 18 is hinged to a shelf 21. The middle of the lower end of the machine body 1 is provided with a shrinkage groove 24, and an electric cylinder 25 is fixed in the shrinkage groove 24. A pressure plate 26 connected to the power end of the electric cylinder 25 is provided below the machine body 1. A spring return rod 19 is fixed at the top end of each groove 18, and a retaining ball 20 is connected to the lower end of each spring return rod 19. A retaining groove 22 is provided at the upper end of each shelf 21, and the retaining ball 20 is engaged in the retaining groove 22. A semi-circular pull ring 23 is fixed at the upper end of the inner side of each shelf 21.

[0030] After the drone inspection is completed, when it is necessary to transport the toolbox to the worker using the drone, the storage plate 21 is pulled out of the groove 18 by the pull ring 23. At this time, the storage plate 21 will push the locking ball 20 upward along the arc surface of the locking ball 20. The locking ball 20 will compress the spring return rod 19 until the storage plate 21 is unfolded and the unfolded storage plate 21 is set at a 90-degree angle with the support plate 4. The inspection and maintenance toolbox is placed on the unfolded storage plate 21, and then the extension of the electric cylinder 25 drives the pressure plate. 26. Press the tool box firmly onto the shelf 21 to secure it, preventing it from falling off during transport. This allows the drone to conveniently transport the tool box for inspection and repair to workers, effectively improving the drone's functionality. When not in use, the shelf 21 can be easily stored in the groove 18, and the spring return rod 19 causes the locking ball 20 to engage in the slot 22, preventing the shelf 21 from accidentally unfolding and ensuring the drone's normal flight inspection.
