[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, a low-altitude inspection drone includes a drone body 1, a mounting shell 2 bolted to the lower side of the drone body 1, a camera 4 mounted on the lower side of the mounting shell 2, and a transparent cover 5. The drone body 1 is existing technology and will not be described in detail here. The mounting shell 2 has a transmission cavity 201 and a storage cavity 202 on its upper and lower sides. The camera 4 has symmetrically arranged lifting plates 6 on its left and right sides, which are slidably connected to the storage cavity 202. The upper sides of the two lifting plates 6 are slidably connected to the translation plates 7 by sliders and slides. The upper sides of the two translation plates 7 are bolted to the cleaning seats 11. The opposite sides of the two cleaning seats 11 are symmetrically opened with cleaning... The cleaning tank has a brush 12 on its inner side. The upper sides of the two sliding plates 7 are equipped with a sliding component that drives the sliding plates 7 to slide left and right along the lifting plate 6. The cleaning tank can fit against the outer side of the transparent cover 5 under the action of the sliding component. The opposite sides of the left and right lifting plates 6 are respectively equipped with a water mist nozzle 13 and an air blowing nozzle 14. The water mist nozzle 13 and the air blowing nozzle 14 are both located above the cleaning seat 11. The water mist nozzle 13 and the air blowing nozzle 14 are respectively connected to a water spray component and an air spray component located on the left and right sliding plates 7. The transmission cavity 201 is symmetrically equipped with two sets of left and right lifting components. The left and right lifting components drive the left and right lifting plates 6 to slide up and down respectively.

[0021] The storage cavity 202 is equipped with a rotating component that drives the camera 4 to rotate.

[0022] When cleaning the transparent cover 5, the staff controls two sets of lifting components to slide the two lifting plates 6 downward and extend them to the lower side of the mounting shell 2. Then, the staff rotates the transparent cover 5 and the camera 4 by rotating the components. While the transparent cover 5 and the camera 4 are rotating, the staff controls the water spray component to spray water mist from the water mist nozzle 13 onto the transparent cover 5. After spraying, the staff controls the air spray component to blow air from the air nozzle 14 onto the transparent cover 5, blowing away water droplets and dirt from the surface of the transparent cover 5. After blowing, the staff controls two sets of translation components to move the two translation plates 7 along the lifting plates 6 toward the transparent cover 5 and make the transparent cover 5 contact the inner side of the cleaning tank. At this time, the brush 12 on the inner side of the cleaning tank can perform a secondary cleaning on the outer side of the transparent cover 5, improving the cleanliness of the outer side of the transparent cover 5 and ensuring the shooting effect of the camera 4.

[0023] After cleaning, the staff controlled the rotating components to stop the rotation of the transparent cover 5 and the camera 4. Then, they controlled the two sets of translation components to move the two translation plates 7 away from the transparent cover 5 to their initial positions. Finally, under the action of the two sets of lifting components, the two lifting plates 6 slid upward until the lower side of the lifting plate 6 was flush with the lower side of the mounting shell 2, and the lifting plate 6 was stored in the storage cavity 202. This prevented the components on the upper side of the lifting plate 6 from being contaminated with dust and debris due to being left outside the storage cavity 202, thus maintaining the cleaning effect on the transparent cover 5.

[0024] In this embodiment, the translation assembly includes a translation motor 15 bolted to the upper side of the translation plate 7, a rack 17 bolted to the upper side of the lifting plate 6, and a gear 16 mounted on the output shaft of the translation motor 15. The gear 16 and the rack 17 mesh with each other. In use, the translation motor 15 can drive the gear 16 to rotate on the rack 17. Under the action of the meshing of the gear 16 and the rack 17, the translation motor 15 can push the translation plate 7 to slide left and right on the lifting plate 6.

[0025] In this embodiment, the water spray assembly includes a water tank 18 bolted to the upper side of the translation plate 7 and a small water pump 19 bolted to the upper side of the water tank 18. The pumping end of the small water pump 19 is inserted into the water tank 18, and a rubber hose 21 is provided between the pump output end and the water mist nozzle 13. A water inlet 181 is provided on the upper side of the water tank 18. In use, the water pump can draw water from the water tank 18 and deliver it to the water mist nozzle 13, thus enabling the water mist nozzle 13 to clean the transparent cover 5. When the water in the water tank 18 is insufficient, the staff can add water to the water tank 18 through the water inlet 181, ensuring the cleaning effect of the water mist nozzle 13 on the transparent cover 5.

[0026] In this embodiment, the jet assembly includes a miniature air pump 20 that is bolted to the upper side of the translation plate 7. A rubber hose 21 is provided between the air delivery end of the miniature air pump 20 and the air blowing nozzle 14. In use, the miniature air pump 20 can compress air and spray it out through the air blowing nozzle 14, thereby cleaning the surface of the transparent cover 5.

[0027] In this embodiment, the lifting assembly includes a drive shaft 8 rotatably connected to the storage cavity 202 via bearings and a lifting motor 9 bolted to the transmission cavity 201. The upper end of the drive shaft 8 passes through the storage cavity 202 and is located in the transmission cavity 201. The upper end of the drive shaft 8 and the output end of the lifting motor 9 are both provided with a first bevel gear 10 that meshes with each other. The lifting plate 6 is threadedly connected to the drive shaft 8. In use, the lifting motor 9 drives the drive shaft 8 to rotate under the action of the first bevel gear 10. The outer surface of the drive shaft 8 has a drive thread, and the lifting plate 6 has a threaded hole that matches the drive thread. The drive shaft 8 drives the lifting plate to move up and down through the drive thread.

[0028] In this embodiment, the rotating assembly includes a rotating plate 3 rotatably connected to the lower side of the mounting housing 2 via bearings, a bevel gear disk 22 bolted to the upper side of the rotating plate 3, and a rotating motor 23 bolted to the receiving cavity 202. The output shaft of the rotating motor 23 is provided with a second bevel gear 24 that meshes with the bevel gear disk 22. The transparent cover 5 and the camera 4 are both bolted to the lower side of the rotating plate 3, and the camera 4 is located inside the transparent cover 5. In use, the rotating motor 23 can drive the second bevel gear 24. Because the second bevel gear 24 meshes with the bevel gear disk 22, the rotating motor 23 can drive the rotating plate 3 to rotate, thereby realizing the rotation of the transparent cover 5 and the camera 4.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
