Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV with foldable arms for geological exploration and photography. Background Technology

[0002] In recent years, the application of drone technology in the field of geological exploration has become increasingly widespread. Multi-rotor drones, with their characteristics of vertical take-off and landing and low-altitude hovering, can carry professional equipment such as high-precision visible light sensors, multispectral cameras and lidar, demonstrating unique advantages in tasks such as mineral resource surveys, geological disaster monitoring and topographic mapping.

[0003] However, multi-rotor drones are limited by their fixed arm structure. When the arms are extended, they are too large and are prone to rubbing against vegetation when carried in mountainous areas, making them inconvenient to transport.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a drone with foldable arms for geological exploration and photography to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a foldable-arm drone for geological exploration and photography, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foldable-arm geological exploration and photography drone includes a connecting plate. The lower end of the connecting plate is fixedly connected to the drone body, and the lower end of the drone body is fixedly mounted with a geological exploration and photography device. The connecting plate has multiple evenly distributed T-slots, and T-plates are slidably connected within each T-slot. A first power assembly is configured between the multiple T-plates to drive the T-plates to slide along the inner wall of the T-slot. A first opening slot is formed at the other end of each T-plate, and a second rotating plate is rotatably connected to the inner wall of the first opening slot. A propeller is configured at the other end of the second rotating plate, and a second power assembly is configured between the propeller and the connecting plate to drive the second rotating plate to rotate.

[0008] In a further technical solution, the connecting plate is provided with multiple through slots.

[0009] In a further technical solution, the first power assembly includes a motor, a fixed disk, connecting ears, and a first rotating plate; a motor is fixedly connected to the intersection of the inner bottom ends of multiple T-shaped plates, the driving end of the motor is fixedly connected to the fixed disk, multiple evenly distributed connecting ears are fixedly connected to the outer wall of the fixed disk, and the other end of each connecting ear is rotatably connected to the first rotating plate, and the other end of the first rotating plate is rotatably connected to the corresponding T-shaped plate.

[0010] In a further technical solution, the lower end of the fixed plate is provided with an embedding groove around the motor, and the upper end of the connecting plate is fixedly connected with a mating ring, and the upper end of the mating ring abuts against the inner wall of the embedding groove.

[0011] In a further technical solution, the second power component includes a second opening groove, a sliding groove, a sliding plate, a third rotating plate, and a fixing plate; multiple fixing plates are fixedly connected to the connecting plate, and the fixing plates correspond one-to-one with the second rotating plate; the second rotating plate is provided with a second opening groove, and sliding grooves are provided on both inner sidewalls of the second opening groove; a sliding plate is slidably connected between the two sliding grooves, and a third rotating plate is rotatably connected between the sliding plate and the fixing plate.

[0012] A further technical solution is that when the connecting ear is collinear with the corresponding first rotating plate, the end of the slide away from the connecting plate abuts against the inner sidewall of the end of the slide groove close to the connecting plate, and the second rotating plate is collinear with the T-shaped plate.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. Geological exploration photography equipment is used to conduct geological exploration photography. The first power component controls multiple T-shaped plates to move closer or further apart. When the first power component moves the multiple T-shaped plates closer together, the T-shaped plates move the second rotating plate closer to the fixed plate. Since the length of the third rotating plate is fixed, the third rotating plate moves the slide plate along the inner wall of the slide groove to the end away from the fixed plate, thereby pushing the second rotating plate to rotate and descend, thus folding the second rotating plate. This effectively avoids the T-shaped plates and the second rotating plate from being too large after unfolding, which could cause them to be scratched during mountain transportation, thus facilitating transportation.

[0015] 2. The stability of the fixed plate can be increased by the matching ring, thereby preventing the fixed plate from shaking in the radial direction due to the motor drive end. This ensures that the sliding trajectory of the T-shaped plate in the T-slot is precise and controllable, effectively avoiding jamming or offset when the arm is unfolded or folded.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model 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 only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown in the figure, this utility model embodiment provides a foldable-arm geological exploration photography drone, including a connecting plate 1. The lower end of the connecting plate 1 is fixedly connected to the drone body (not shown in the figure), and the lower end of the drone body is fixedly provided with a geological exploration photography device (not shown in the figure). The connecting plate 1 has a plurality of evenly distributed T-shaped grooves 2, and T-shaped plates 3 are slidably connected in each of the T-shaped grooves 2. A first power assembly 4 is provided between the plurality of T-shaped plates 3, and the first power assembly 4 is used to drive the T-shaped plates 3 to slide along the inner wall of the T-shaped grooves 2. The other end of each T-shaped plate 3 has a first opening groove 5, and a second rotating plate 6 is rotatably connected to the inner wall of the first opening groove 5. A propeller 7 is provided at the other end of the second rotating plate 6. A second power assembly 8 is also provided between the propeller 7 and the connecting plate 1, and the second power assembly 8 is used to drive the second rotating plate 6 to rotate.

[0024] Furthermore, the connecting plate 1 has multiple through slots 9, thereby effectively reducing the weight of the connecting plate 1.

[0025] like Figure 1 and Figure 3As shown, the first power assembly 4 includes a motor 41, a fixed disk 42, connecting ears 43, and a first rotating plate 44; the motor 41 is fixedly connected to the intersection of the inner bottom ends of multiple T-shaped plates 3, the driving end of the motor 41 is fixedly connected to the fixed disk 42, multiple evenly distributed connecting ears 43 are fixedly connected to the outer wall of the fixed disk 42, and the other end of each connecting ear 43 is rotatably connected to the first rotating plate 44, and the other end of the first rotating plate 44 is rotatably connected to the corresponding T-shaped plate 3.

[0026] Furthermore, the lower end of the fixed plate 42 is provided with an embedding groove (not shown in the figure) around the motor 41, and the upper end of the connecting plate 1 is fixedly connected with a mating ring 45, and the upper end of the mating ring 45 abuts against the inner wall of the embedding groove.

[0027] In a specific application, the drive end of the motor 41 drives the fixed disk 42 to rotate. The fixed disk 42 rotates relative to the mating ring 45. Then, the fixed disk 42 drives the connecting ear 43 to rotate around the axis of the fixed disk 42. Then, the connecting ear 43 drives the T-shaped plate 3 to slide along the inner wall of the corresponding T-shaped groove 2 through the first rotating plate 44. The mating ring 45 can increase the stability of the fixed disk 42 during rotation.

[0028] like Figure 1 and Figure 2 As shown, the second power assembly 8 includes a second opening groove 81, a sliding groove 82, a sliding plate 83, a third rotating plate 84, and a fixing plate 85; multiple fixing plates 85 are fixedly connected to the connecting plate 1, and the fixing plates 85 correspond one-to-one with the second rotating plate 6. The second rotating plate 6 has a second opening groove 81, and the two inner side walls of the second opening groove 81 are provided with sliding grooves 82. A sliding plate 83 is slidably connected between the two sliding grooves 82, and a third rotating plate 84 is rotatably connected between the sliding plate 83 and the fixing plate 85.

[0029] Furthermore, when the connecting ear 43 is collinear with the corresponding first rotating plate 44, the end of the sliding plate 83 away from the connecting plate 1 abuts against the inner sidewall of the end of the sliding groove 82 close to the connecting plate 1, and the second rotating plate 6 is collinear with the T-shaped plate 3.

[0030] In practical applications, when the first power assembly 4 drives multiple T-shaped plates 3 to move closer to each other, the T-shaped plates 3 drive the second rotating plate 6 to move towards the fixed disk 42. Since the length of the third rotating plate 84 is fixed, the third rotating plate 84 drives the slide plate 83 to slide along the inner wall of the slide groove 82 towards the end away from the fixed disk 42, thereby pushing the second rotating plate 6 to rotate and descend. When the first power assembly 4 drives multiple T-shaped plates 3 to move away from each other, the T-shaped plates 3 drive the second rotating plate 6 to move away from the fixed disk 42. Since the length of the third rotating plate 84 is fixed, the third rotating plate 84 drives the slide plate 83 to slide along the inner wall of the slide groove 82 towards the end near the fixed disk 42, thereby pushing the second rotating plate 6 to rotate and rise.

[0031] In this embodiment of the invention, geological exploration photography is performed using a geological exploration photography device. Multiple T-shaped plates 3 are controlled to move closer or further apart using a first power component 4. When the first power component 4 moves the multiple T-shaped plates 3 closer together, the T-shaped plates 3 drive the second rotating plate 6 to move closer to the fixed plate 42. Since the length of the third rotating plate 84 is fixed, the third rotating plate 84 drives the sliding plate 83 to slide along the inner wall of the sliding groove 82 towards the end away from the fixed plate 42, thereby pushing the second rotating plate 6 to rotate and descend, thus folding the second rotating plate 6. This effectively prevents the T-shaped plates 3 and the second rotating plate 6 from becoming too large after unfolding, thus avoiding scratches during mountain transportation and facilitating transport. The mating ring 45 increases the stability of the fixed plate 42, preventing the motor 41 from driving the fixed plate 42 to shake radially, thereby ensuring that the sliding trajectory of the T-shaped plates 3 within the T-groove 2 is precise and controllable, effectively preventing jamming or offset when the arm unfolds or folds.

[0032] The working principle of this utility model is as follows: When it is necessary to retract the T-shaped plate 3 and the second rotating plate 6, the first power component 4 drives multiple T-shaped plates 3 to move closer to each other. The T-shaped plates 3 drive the second rotating plate 6 to move towards the fixed plate 42. Since the length of the third rotating plate 84 is fixed, the third rotating plate 84 drives the slide plate 83 to slide along the inner wall of the slide groove 82 towards the end away from the fixed plate 42, thereby pushing the second rotating plate 6 to rotate and descend. When it is necessary to unfold the T-shaped plate 3 and the second rotating plate 6, the first power component 4 drives multiple T-shaped plates 3 to move away from each other. The T-shaped plates 3 drive the second rotating plate 6 to move away from the fixed plate 42. Since the length of the third rotating plate 84 is fixed, the third rotating plate 84 drives the slide plate 83 to slide along the inner wall of the slide groove 82 towards the end near the fixed plate 42, thereby pushing the second rotating plate 6 to rotate and rise.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
