Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicles (UAVs), specifically to a lightweight UAV-mounted surveying equipment. Background Technology

[0002] With the development of lightweight drone technology and the miniaturization of surveying equipment, cameras, as one of the core surveying devices, are widely used in scenarios such as monitoring crop growth, acquiring on-site images of geological disasters, urban surveying, and emergency rescue target positioning. They need to acquire high-definition, multi-angle surveying images to provide basic data support for subsequent data analysis (such as crop pest and disease identification, disaster area zoning assessment, and terrain modeling).

[0003] Currently, survey cameras mounted on lightweight drones have been miniaturized. However, in practical applications, the placement of the camera is particularly important. Significant technical deficiencies remain in the flexibility of angle adjustment and the ease of mounting. Adjustment relies on manual operation on the ground and cannot be dynamically adjusted in real time. Furthermore, existing mounting connections mostly rely on mechanical fasteners (such as hex bolts and Phillips head screws), and disassembly and assembly require special tools (such as hex wrenches and screwdrivers), which are time-consuming and cannot meet the needs of actual use.

[0004] Therefore, there is a need to provide a lightweight UAV-mounted surveying device to solve the above problems. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0029] See Figures 1 to 7 A lightweight unmanned aerial vehicle (UAV) mounted surveying equipment includes a UAV body 1, an illumination lamp 41 for lighting, a mounting bracket 2 fixedly mounted on the UAV body 1, a mounting shell 11 mated to the mounting bracket 2, and a camera 12 for surveying movably mounted on the mounting shell 11. The equipment also includes: The mounting mechanism is installed at the connection between the mounting connector 2 and the mounting shell 11. It is used for mounting and disassembling the mounting shell 11. The mounting mechanism includes a docking mounting seat 5 for docking the mounting connector 2. The docking mounting seat 5 is fixedly connected to a rotating base 7 via a docking post 6. The mounting shell 11 is mounted on the output shaft of the rotating base 7. A limiting rod 8 for limiting connection is provided at the docking mounting seat 5 and the mounting connector 2. The limiting rod 8 is telescopically connected to the inside of the docking mounting seat 5.

[0030] Furthermore, the mounting and installation mechanism also includes a mounting groove 3 for adapting to the docking mounting seat 5. The mounting groove 3 is opened on the mounting connection seat 2 and is adapted to the docking mounting seat 5 for installation and connection. The docking mounting seat 5 is provided with a telescopic hole 10 adapted to the sliding connection limit rod 8. A return spring 9 is provided at the connection between the limit rod 8 and the telescopic hole 10. The mounting groove 3 is provided with a limit hole 4 adapted to the limit rod 8 for insertion.

[0031] Furthermore, the mounting mechanism also includes a reset contact rod 24 for driving the limit rod 8 away from the limit. The reset contact rod 24 is coaxially arranged with the limit hole 4. The reset contact rod 24 is fixedly installed on the first L-shaped connecting plate 22 and the second L-shaped connecting plate 23. The first L-shaped connecting plate 22 and the second L-shaped connecting plate 23 are arranged in parallel. The inner sides of the first L-shaped connecting plate 22 and the second L-shaped connecting plate 23 are provided with teeth that mesh with the transmission gear 21.

[0032] Furthermore, the mounting mechanism also includes a knob 15 for driving the transmission gear 21 to rotate. The transmission gear 21 is rotatably connected to the inside of the mounting connection seat 2 via a second connecting shaft 20. A worm gear 19 is fixedly connected to the second connecting shaft 20, and a worm 18 is meshed on the worm gear 19. The worm 18 is rotatably connected to the mounting connection seat 2. The worm 18 is rotatably connected to a first connecting shaft 16 via a synchronous belt 17. The first connecting shaft 16 is rotatably mounted on the mounting connection seat 2, and a knob 15 is fixedly connected to one end of the first connecting shaft 16.

[0033] Preferably, during mounting, the camera 12 can be screwed or snapped onto the camera mounting base 14. When the mounting shell 11 is mounted and connected, the mating mounting base 5 on the mounting shell 11 is fitted into the mounting groove 3 on the mounting connection base 2. The limiting rod 8 on the mating mounting base 5 compresses and extends the return spring 9 inside the telescopic hole 10. When the limiting rod 8 on the mating mounting base 5 moves to a position coaxial with the limiting hole 4, the limiting rod 8 extends under the elastic action of the return spring 9. At this time, the limiting rod 8 extends into the limiting hole 4 for limiting, thereby completing the mounting and fixing of the mounting shell 11.

[0034] When the mounting shell 11 needs to be removed for maintenance, the rotary knob 15 is adjusted to rotate the first connecting shaft 16. Under the synchronous drive of the synchronous belt 17, the worm gear 18 is driven to rotate. Under the meshing connection between the worm gear 18 and the worm wheel 19, the transmission gear 21 on the second connecting shaft 20 is driven to rotate. Thus, under the meshing connection between the transmission gear 21 and the inner teeth of the first L-shaped connecting plate 22 and the second L-shaped connecting plate 23, the reset contact rod 24 on the first L-shaped connecting plate 22 and the second L-shaped connecting plate 23 is driven to press and move towards the axis of the limiting hole 4. When the limiting rod 8 pressed by the reset contact rod 24 is completely disengaged from the junction with the limiting hole 4, the mating mounting seat 5 on the mounting shell 11 can be completely disengaged from the upper limit hole 4 of the mounting connecting seat 2, thus facilitating the disassembly and installation of the mounting shell 11. The mounting and installation are simple and easy to use.

[0035] The mounting mechanism makes the disassembly and installation of the mounting shell 11 easier, significantly reducing downtime and thus improving the efficiency of surveying operations. In addition, this convenient disassembly and installation not only optimizes the "operation process" but also makes subsequent maintenance more efficient. This wear-free limiting method can further extend the service life of the equipment and facilitate mounting, installation and use.

[0036] like Figures 1-9 As shown, this embodiment, based on the above embodiment, also includes a surveying and adjustment mechanism, which is installed at the connection between the camera 12 and the mounting housing 11, and is used to drive the camera 12 to perform surveying and adjustment processing. The surveying and adjustment mechanism includes a first fixed frame 25, a first fixed rod 26 and a second fixed rod 27 for adjusting the surveying angle of the camera 12. The first fixed rod 26 and the second fixed rod 27 are fixedly connected perpendicularly to each other. The first fixed frame 25 is rotatably connected to the first fixed rod 26. A camera mounting base 14 is provided at the center of the first fixed frame 25, and the camera 12 is movable and limited to be mounted on the camera mounting base 14.

[0037] Furthermore, the surveying and adjustment mechanism also includes a second toothed plate 36 and a second guide block 37 for driving the first fixed frame 25 to swing and adjust. A second gear 35 is fixedly connected to the first fixed rod 26, and the second toothed plate 36 is meshed with the second gear 35. The second toothed plate 36 is limited and slidably connected to the inside of the second guide block 37. The second guide block 37 is fixedly installed on the second docking block 38, and the second docking block 38 is rotatably connected to the first fixed rod 26.

[0038] Furthermore, the surveying and adjustment mechanism also includes a second push rod 39 for driving the second toothed plate 36 to move and connect. The second toothed plate 36 is fixedly connected to the piston rod of the second push rod 39, and the second push rod 39 is fixedly installed on the first fixed frame 25 through the second support seat 40.

[0039] Furthermore, the surveying and adjustment mechanism also includes a first toothed plate 29 and a first guide block 30 for driving the first fixed rod 26 and the second fixed rod 27 to swing and adjust. A first gear 28 is fixedly connected to the second fixed rod 27, and the first toothed plate 29 is meshed with the first gear 28. The first toothed plate 29 is slidably connected to the inside of the first guide block 30. The first guide block 30 is fixedly connected to the first docking block 31, and the first docking block 31 is fixedly installed on the second fixed frame 34.

[0040] Furthermore, the surveying and adjustment mechanism also includes a first electric push rod 32 for driving the first toothed plate 29 to move and connect. The first toothed plate 29 is fixedly connected to the piston rod of the first electric push rod 32. The first electric push rod 32 is fixedly installed on the second fixed frame 34 through the first support base 33. The second fixed rod 27 is rotatably connected to the second fixed frame 34. The second fixed frame 34 is fixedly installed inside the mounting shell 11.

[0041] Preferably, in this embodiment, when adjusting the angle of the drone-mounted survey, since an elastic plastic cloth 13 is provided at the connection between the camera mounting base 14 and the mounting shell 11, and the elastic plastic cloth 13 is made of a corresponding elastic material, it is convenient to swing the camera 12 on the camera mounting base 14 at will.

[0042] When adjusting the survey angle, the second push rod 39 drives the second toothed plate 36 to move, thereby driving the first fixed frame 25 to move the camera 12 laterally under the meshing connection between the second toothed plate 36 and the second gear 35 and the rotational connection between the second docking block 38 and the first fixed rod 26, thus completing the lateral swing adjustment of the camera 12. When the longitudinal swing adjustment of the camera 12 is required, the first electric push rod 32 drives the first toothed plate 29 to move, thereby driving the first fixed rod 26 and the second fixed rod 27 to move the camera 12 on the first fixed frame 25 to move longitudinally under the meshing connection between the first toothed plate 29 and the first gear 28 and the rotational connection between the second fixed frame 34 and the second fixed rod 27, thus driving the first fixed rod 26 and the second fixed rod 27 to move the camera 12 on the first fixed frame 25 to move longitudinally. (See details...) Figure 8 and Figure 9 As shown, the rotating base 7 above drives the mounting shell 11 to rotate, thereby enabling the camera 12 to be used for surveying and adjustment in any angle direction. The range of surveying angle adjustment is wide, further improving the surveying efficiency of this lightweight UAV.

[0043] Traditional light drone surveying often uses a fixed angle (such as a single vertical overhead shot), which can easily create blind spots due to terrain obstruction and differences in target shape. However, the structure adopted in this application can adjust the angle arbitrarily, and by flexibly switching the perspective, it can cover areas that are difficult to reach by traditional methods, thereby facilitating better acquisition of survey data, meeting the needs of diverse scenarios, further improving survey efficiency, and making it convenient for surveying use.

[0044] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
