[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a road crack inspection unmanned aerial vehicle capable of spraying marks. Background Technique

[0002] With the acceleration of the urbanization process, road maintenance has become an indispensable part of urban management. Road cracks, as an early manifestation of road damage, their timely detection and repair are of great significance for ensuring driving safety and extending the service life of roads.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: A road crack inspection unmanned aerial vehicle capable of spraying marks, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes an unmanned aerial vehicle frame 1, rotating rotors 2, landing gears 3, spraying cylinders 4, mounting frames 41, storage cylinders 5, and driving motors 6. Four equally spaced rotating rotors 2 are rotatably connected to the upper side of the unmanned aerial vehicle frame 1. Left and right symmetric landing gears 3 are fixedly connected to the lower side of the unmanned aerial vehicle frame 1. A mounting frame 41 is fixedly connected to the front part of the lower side of the unmanned aerial vehicle frame 1. A spraying cylinder 4 is rotatably connected to the lower part of the mounting frame 41. A storage cylinder 5 is fixedly connected to the rear part of the lower side of the unmanned aerial vehicle frame 1. The storage cylinder 5 is communicated with the spraying cylinder 4 through a hose. A driving motor 6 is fixedly connected to the lower part of the mounting frame 41. The output shaft of the driving motor 6 is connected to the spraying cylinder 4.

[0027] When using this device, the rotating rotors 2 operate to drive the device to fly. When a crack is detected, the driving motor 6 operates to control the spraying cylinder 4 to rotate downward to adjust the angle, and the paint is sprayed on the crack through the spraying cylinder 4 for marking. Under the action of the hose, the storage cylinder 5 can supply materials to the spraying cylinder 4. After spraying is completed, the driving motor 6 controls the spraying cylinder 4 to rotate upward to reset.

[0028] Example 2: On the basis of Example 1, as Figure 1 and Figure 5 shown, it further includes a guiding component for guiding the sprayed coating. The guiding component includes a connecting frame 7 and a guiding cylinder 8. The front part of the spraying cylinder 4 is fixedly connected with symmetric connecting frames 7 on the left and right. A guiding cylinder 8 is fixedly connected between the two connecting frames 7 on the left and right. The front end of the spraying cylinder 4 extends into the guiding cylinder 8.

[0029] When using this device, the coating sprayed from the spraying cylinder 4 will pass through the guiding cylinder 8 and be marked on the crack. The guiding cylinder 8 guides and blocks the coating sprayed from the spraying cylinder 4 to avoid the influence of the airflow generated by the rotation of the rotating rotor 2 on the position of the coating mark. Under the action of the connecting frame 7, the guiding cylinder 8 will rotate and adjust the angle together with the spraying cylinder 4.

[0030] As Figure 1 , Figure 6 and Figure 7 shown, it further includes a stirring component for preventing the coating from precipitating. The stirring component includes a pushing plate 9, a rotating rod 10, a first gear 11, a second gear 12, a stirring frame 13 and a torsion spring 131. The rear side of the spraying cylinder 4 is fixedly connected with a pushing plate 9. The lower right part of the unmanned aerial vehicle frame 1 is rotatably connected with a rotating rod 10 through a bracket. A convex rod is provided at the front end of the rotating rod 10. The pushing plate 9 is in pressing fit with the convex rod. The rear part of the rotating rod 10 is fixedly connected with a first gear 11. A stirring frame 13 is rotatably connected in the storage cylinder 5. The rear end of the stirring frame 13 is fixedly connected with a second gear 12. The second gear 12 meshes with the first gear 11. A torsion spring 131 is connected between the rotating rod 10 and the bracket.

[0031] When using this device, when the spraying cylinder 4 rotates downward, the pushing plate 9 will swing upward. The upward swing of the pushing plate 9 drives the rotating rod 10, and the torsion spring 131 deforms. The rotation of the rotating rod 10 drives the first gear 11 to rotate. The rotation of the first gear 11 drives the second gear 12 to rotate. The rotation of the second gear 12 drives the stirring frame 13 to rotate. The rotation of the stirring frame 13 can stir the coating in the storage cylinder 5 to avoid the precipitation of the coating. When the spraying cylinder 4 rotates upward and resets to drive the pushing plate 9 to reset, under the action of the reset of the torsion spring 131, the rotating rod 10 rotates reversely to drive the first gear 11 and the second gear 12 to flip, and the stirring frame 13 rotates reversely to stir the coating in the storage cylinder 5 again.

[0032] As Figure 8As shown, it further includes a cleaning component for cleaning the residual paint on the inner wall of the guiding cylinder 8. The cleaning component includes a pulling ring 14, a cleaning frame 15, a guiding rod 16 and an elastic member 17. The guiding cylinder 8 is slidably connected to the guiding rods 16 on both the upper and lower sides. A pulling ring 14 is fixedly connected between the front parts of the upper and lower guiding rods 16. A cleaning frame 15 is fixedly connected to the pulling ring 14. The cleaning frame 15 extends into the guiding cylinder 8 and fits against the inner wall of the guiding cylinder 8. An elastic member 17 is connected between the guiding rod 16 and the guiding cylinder 8.

[0033] When using this device, the staff controls the pulling ring 14 to move forward. The forward movement of the pulling ring 14 drives the guiding rod 16 to slide forward, and the elastic member 17 deforms. While the pulling ring 14 moves forward, it drives the cleaning frame 15 to move forward. The forward movement of the cleaning frame 15 can clean the paint adhered to the inside of the guiding cylinder 8. After the cleaning is completed, the staff releases the pulling ring 14. Under the action of the reset of the elastic member 17, the guiding rod 16 drives the pulling ring 14 and the cleaning frame 15 to move backward and reset.
