[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figures 1-7 As shown in the illustration, this application discloses a UAV remote sensing and mapping device, including a mounting box 10, a lifting plate 11, a drive assembly 20, a remote sensing sensor 12, and a protection assembly 30. The mounting box 10 is located at the bottom of the UAV with its opening facing downwards. The lifting plate 11 is vertically slidably disposed within the mounting box 10. The drive assembly 20 is disposed within the mounting box 10 and is used to drive the lifting plate 11 to rise and fall. The remote sensing sensor 12 is disposed at the bottom of the lifting plate 11. There are two protection assemblies 30, which are symmetrically disposed at the bottom of the mounting box 10. Each protection assembly 30 includes two connecting posts 31 respectively disposed on both sides of the lifting plate 11. The mounting box 10 has a slotted hole 32 corresponding to the connecting post 31. One end of the connecting post 31 passes through the slotted hole 32 and is rotatably connected to a connecting rod 33. A protective cover 34 is hinged to the bottom of the mounting box 10. Fixed posts 35 are disposed on both sides of the protective cover 34. The end of the connecting rod 33 away from the connecting post 31 is rotatably connected to the fixed post 35. Before the UAV takes off or lands, the drive assembly 20 drives the lifting plate 11 upward, thereby raising the remote sensing sensor 12 into the mounting box 10. Simultaneously, the upward movement of the lifting plate 11 is transmitted to the connecting rod 33 via four connecting columns 31, driving the two protective covers 34 to rotate synchronously. As the protective covers 34 rotate, they gradually close, eventually completely covering the bottom opening of the mounting box 10, forming a sealed protective space. This prevents the airflow generated by the propeller from stirring up sand, dust, and other particles that could impact the remote sensing sensor 12, thus maximizing the protection of the remote sensing sensor 12 from damage and ensuring its measurement accuracy and stability.

[0028] In order to avoid the particles such as sand and dust from entering the inside of the mounting box 10 through the strip-shaped hole 32, the baffle 40 is arranged on the connecting column 31, and the side of the baffle 40 away from the lifting plate 11 is in contact with the inner wall of the mounting box 10. The lifting plate 11 is lifted to drive the connecting column 31 and the baffle 40 to rise. When the protective cover 34 completely covers the bottom opening of the mounting box 10, the baffle 40 blocks the strip-shaped hole 32. The size of the baffle 40 is greater than that of the strip-shaped hole 32, so that the baffle 40 can completely block the strip-shaped hole 32. In order to avoid the baffle 40 from shaking and causing a gap between the baffle 40 and the inner wall of the mounting box 10 when a large airflow generated by the propeller impacts the baffle 40, the mounting strips 41 are arranged on both sides of the baffle 40. The sliding grooves 42 are arranged on the mounting strips 41. The two sides of the baffle 40 are respectively connected with the corresponding sliding grooves 42 in a sliding manner. The baffle 40 is limited by the mounting strips 41 and the sliding grooves 42, so that the gap between the baffle 40 and the inner wall of the mounting box 10 is avoided.

[0029] Specifically, the driving assembly 20 includes mounting plates 21, linkage synchronous pulleys 23 and a first synchronous belt 24. The mounting plates 21 are two, and the two mounting plates 21 are arranged on the opposite two inner walls of the mounting box 10. The threaded rods 22 are vertically arranged between the two mounting plates 21 and the top of the mounting box 10. The linkage synchronous pulleys 23 are two, and the two linkage synchronous pulleys 23 are fixedly sleeved on the upper ends of the two threaded rods 22. The two linkage synchronous pulleys 23 are connected by the first synchronous belt 24, so that the two threaded rods 22 are synchronously rotated. The connecting blocks 25 are arranged on the two sides of the lifting plate 11, and the connecting blocks 25 are connected with the corresponding threaded rods 22 in a threaded hole. The two threaded rods 22 are synchronously rotated, and the lifting plate 11 is stably driven to slide by the two connecting blocks 25.

[0030] When arranged, the driven synchronous pulley 26 is fixedly sleeved on one of the threaded rods 22. The driving motor 27 is vertically arranged on the inner wall of the mounting box 10. The output shaft of the driving motor 27 is upwardly provided with the driving synchronous pulley 28. The driving synchronous pulley 28 and the driven synchronous pulley 26 are connected by the second synchronous belt 29. The driving motor 27 drives the driving synchronous pulley 28 to rotate, so that the driven synchronous pulley 26 is driven to rotate the threaded rod 22.

[0031] Specifically, sliding rails 13 are vertically arranged on the two inner walls of the mounting box 10, and the lifting plate 11 is connected to the corresponding sliding rail 13 through a sliding block. The stability of the lifting plate 11 is ensured. The protective cover 34 includes two protective plates 341 arranged at intervals and a connecting plate 342 connecting the two protective plates 341, the connecting plate 342 is hinged to the bottom of the mounting box 10, and the connecting plate 342 and one side of the two protective plates 341 are provided with a cover plate 343, the shape formed by the two cover plates 343 is consistent with the shape of the bottom of the mounting box 10, which ensures that the opening of the bottom of the mounting box 10 can be completely blocked.

[0032] The use principle of the unmanned aerial vehicle remote sensing surveying and mapping device in the embodiment is as follows:

[0033] Before the unmanned aerial vehicle takes off or lands, the driving motor 27 is started to drive the driving synchronous pulley 28 to rotate, thereby driving the driven synchronous pulley 26, the threaded rod 22 and the linkage synchronous pulley 23 to rotate, so that the lifting plate 11 moves upward, thereby lifting the remote sensing sensor 12 to the inside of the mounting box 10. At the same time, the upward movement of the lifting plate 11 is transmitted to the connecting rod 33 through the four connecting columns 31, thereby driving the two protective covers 34 to rotate synchronously. With the rotation of the protective covers 34, they gradually close and finally completely cover the opening at the bottom of the mounting box 10, and the baffle 40 blocks the strip-shaped hole 32, thereby forming a closed protection space.

[0034] After the unmanned aerial vehicle takes off, the driving motor 27 is started to drive the driving synchronous pulley 28 to rotate, thereby driving the driven synchronous pulley 26, the threaded rod 22 and the linkage synchronous pulley 23 to rotate, so that the lifting plate 11 moves downward, and at the same time, the connecting rod 33 is driven to move, so that the protective cover 34 rotates away from the opening at the bottom of the mounting box 10, so that the remote sensing sensor 12 moves out of the inside to take a photo or scan the ground below the unmanned aerial vehicle.

[0035] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application shall also be considered as the protection scope of the present application.
