Description

Technical Field

[0001] This utility model relates to the field of geographic surveying drones, and in particular to an auxiliary device for geographic surveying drones. Background Technology

[0002] An existing patent (publication number: CN115196006A) proposes a geographic mapping drone device, including a frame and legs. The legs are fixed to the bottom of the frame, and a shell is fixed at the center of the bottom of the frame. A mapping camera is installed at the bottom of the shell, and an anti-blurring mechanism is installed inside the shell to automatically clean the dust covering the glass window of the mapping camera from all directions. The anti-blurring mechanism includes a wiping component, a rotation drive mechanism, and a lifting drive mechanism. However, in this device, "the shell is fixed at the center of the bottom of the frame, and the mapping camera is installed at the bottom of the shell," meaning the mapping camera is exposed. It is likely to be damaged by lateral impacts during mapping operations in complex environments, affecting the safety of the mapping process. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a geographic surveying drone auxiliary device. During geographic surveying operations, the drone hovers while the surveying camera performs the surveying work. A synchronous angle-adjusting motor controls the rotation of a driven gear ring via a drive gear. The rotation of the driven gear ring, through a linkage mechanism consisting of an inner connecting rod mounting block, a linkage rod, and a drive rack, controls the rotation of a support cylinder mounting block. This adjusts the tilt angle of the split-type moving protective plate array, causing it to surround the side of the surveying camera and protect it. This effectively prevents damage to the surveying camera from lateral impacts during surveying operations in complex environments, increasing the safety of the surveying process.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A geographic surveying UAV auxiliary device includes a UAV body, a split-type dynamic protective plate, a surveying camera mounting platform, a surveying camera mounting frame, a surveying camera, an angle adjustment motor, a driven gear ring, a drive rack, a load-bearing cylinder mounting block, a deflection circlip, a linkage rod, and a drive gear. The bottom of the UAV body is connected to the surveying camera mounting platform. The bottom of the UAV body has an angle adjustment motor mounting platform, a gear ring mounting platform, a load-bearing cylinder mounting platform, and a side-fixed protective ring. The angle adjustment motor mounting platforms are located on both sides of the surveying camera mounting platform. The gear ring mounting platforms are evenly arranged around the angle adjustment motor mounting platform array, and the load-bearing cylinder mounting platforms are evenly arranged around the gear ring mounting platform array. The side-fixed protective rings are around the outside of the load-bearing cylinder mounting platform array. The bottom of the surveying camera mounting platform is connected to the surveying camera mounting frame, and the bottom of the surveying camera mounting frame is rotatably connected to the surveying camera. The angle adjustment motor is inserted into and fixed inside the angle adjustment motor mounting platform.

[0006] The angle-adjusting motor has a drive shaft fixedly connected to a driving gear, a gear ring mounting platform adapted to a driven gear ring, a gear ring mounting platform connected to a driven gear ring, a driven gear ring rotating inside the gear ring mounting platform, a driving gear meshing with a driven gear ring, an inner connecting rod mounting block on the outer side of the driven gear ring, the inner connecting rod mounting blocks being evenly arranged around the driven gear ring, a rack mounting groove inside the bearing cylinder mounting platform, a drive rack adapted to a rack mounting groove, a drive rack connected to a rack mounting groove, a drive rack sliding inside a rack mounting groove, and an outer connecting rod mounting block on the side of the drive rack facing the driven gear ring.

[0007] One side of the linkage rod is rotatably connected to the inner connecting rod mounting block, and the other side of the linkage rod is rotatably connected to the outer connecting rod mounting block. The bearing cylinder mounting platform is rotatably connected to the bearing cylinder mounting block. The outer side of the bearing cylinder mounting block has rack and pinion teeth that mesh with the drive rack. The bottom of the bearing cylinder mounting block has a protective plate bearing cylinder. The bottom of the protective plate bearing cylinder is provided with a split-type moving protective plate, and the top of the split-type moving protective plate has a protective plate connecting post. Beneficial effects

[0008] 1. During geographic surveying operations, the UAV hovers while the surveying camera performs surveying work. A synchronous angle-adjusting motor controls the rotation of the driven gear ring via an active gear. When the driven gear ring rotates, it controls the rotation of the bearing cylinder mounting block via a linkage mechanism consisting of an inner connecting rod mounting block, a linkage rod, and a drive rack. This adjusts the tilt angle of the split-type moving protective plate array group, allowing the split-type moving protective plate array group to surround the side of the surveying camera and protect it from damage caused by lateral impacts during surveying operations in complex environments.

[0009] 2. The modular dynamic protective plate array of this utility model is arranged in a ring, and all the modular dynamic protective plates are designed at an angle. This allows the modular dynamic protective plate array to protect the surveying camera while guiding the airflow over the surface of the modular dynamic protective plates. This reduces the wind resistance experienced by the modular dynamic protective plate array, increases the stability of the surveying camera during surveying operations, and thus improves the measurement effect of the surveying camera.

[0010] 3. The bearing cylinder mounting platform and the bearing cylinder mounting block of this utility model are rotatably connected, so that the tilt angle of the split-type moving protective plate array can be freely adjusted. When the surveying camera does not need to perform surveying, the tilt angle of the split-type moving protective plate increases, completely blocking the surveying camera and increasing the protective effect of this device. When the surveying camera is performing surveying, the tilt angle of the split-type moving protective plate decreases, and the surveying camera is partially exposed, so as to continuously protect the surveying camera without affecting the surveying operation.

[0011] 4. The protective sheet bearing cylinder of this utility model is equipped with a deflection retaining spring, so that the split-type moving protective sheet is continuously subjected to a deflection force, thereby ensuring that the protective sheet mating ears are pressed tightly inside the protective sheet mating groove when the split-type moving protective sheet is adjusted to various angles, thus maintaining the tightness of the connection between the split-type moving protective sheets.

[0024] A geographic surveying UAV auxiliary device includes a UAV body 1, a split-type dynamic protective plate 3, a surveying camera mounting platform 4, a surveying camera mounting bracket 5, a surveying camera 6, an angle adjustment motor 8, a driven gear ring 10, a drive rack 15, a support cylinder mounting block 16, a deflection circlip 17, a linkage rod 18, and a drive gear 25. The bottom of the UAV body 1 is connected to the surveying camera mounting platform 4. During geographic surveying operations, the UAV body 1 hovers while the surveying camera 6 performs surveying operations. The synchronous angle adjustment motor 8 controls the driven gear ring 10 to rotate via the drive gear 25. When the driven gear ring 10 rotates, it controls the rotation of the support cylinder mounting block 16 via a linkage mechanism consisting of the inner connecting rod mounting block 21, the linkage rod 18, and the drive rack 15, thereby adjusting the tilt angle of the split-type dynamic protective plate array 3. The array of dynamic protective plates 3 surrounds the side of the surveying camera 6 to protect it and effectively prevent it from being damaged by lateral impacts during surveying operations in complex environments. The bottom of the UAV body 1 has an angle adjustment motor mounting platform 7, a toothed ring mounting platform 9, a bearing cylinder mounting platform 14, and a side-fixed protective ring 2. The angle adjustment motor mounting platform 7 is located on both sides of the surveying camera mounting platform 4. The toothed ring mounting platforms 9 are evenly arranged around the array of angle adjustment motor mounting platforms 7.

When the surveying camera 6 is not in use, the tilt angle of the split-type moving protective plate 3 increases, completely blocking the surveying camera 6 and increasing the protective effect of the device. When the surveying camera 6 is in use, the tilt angle of the split-type moving protective plate 3 decreases, and the surveying camera 6 is partially exposed. This provides continuous protection for the surveying camera 6 without affecting its surveying operations. The drive rack 15 is adapted to the rack mounting groove 20.

The top of the split-type moving protective plate 3 has a protective plate connecting post 12. The array of split-type moving protective plates 3 is arranged in a ring, and all split-type moving protective plates 3 are designed with an inclination. This allows the array of split-type moving protective plates 3 to protect the surveying camera 6 while guiding the airflow passing over the surface of the split-type moving protective plates 3, thereby reducing the wind resistance of the array of split-type moving protective plates 3, increasing the stability of the surveying camera 6 during surveying operations, and thus increasing the measurement effect of the surveying camera 6.

[0029] Example 4:
