Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to an aerial photography UAV used for patrol. Background Technology

[0002] Patrol drones are unmanned aerial vehicles specifically designed for aerial monitoring, patrol, and data collection. They combine advanced flight control technology, high-definition camera equipment, and various sensors to perform tasks in different environments, such as power line inspection, urban monitoring, and environmental monitoring. These drones are automatically or manually controlled through precise GPS navigation and remote control systems, and can transmit images, videos, and data in real time.

[0003] Existing aerial drones for patrol purposes still have some problems during use. For example, aerial drones are usually equipped with landing gear, while the drone's camera is mostly located at the bottom of the fuselage. During the drone's flight and filming, the landing gear sometimes obstructs the camera's field of view, resulting in incomplete footage and affecting the effectiveness of the patrol mission. In addition, since the camera is usually located at the bottom of the drone, it is easy for the camera to come into contact with the ground when the drone lands, posing a risk of damage.

[0004] To address these issues, we provide an aerial drone for patrol purposes. Utility Model Content

[0005] The purpose of this invention is to provide an aerial photography drone for patrol purposes. By combining the deployment and storage components, it solves the problems of existing aerial photography drones for patrol purposes, such as the inconvenience of folding the landing gear during takeoff and the inconvenience of storing and protecting the camera.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an aerial photography drone for patrol purposes, comprising a fuselage with a storage box fixedly connected to its bottom. The storage box contains a retraction assembly, which includes a rotating rod movably connected to both sides of the storage box's interior, support bars fixedly connected to both sides of the rotating rod's surface, and a landing gear fixedly connected to one side of the support bars. The retraction assembly is used to retract the drone's landing gear. The storage box also contains a storage component, which includes a toothed plate slidably connected to the storage box's interior, a base fixedly connected to the bottom of one side of the toothed plate, and a camera fixedly connected to one side of the base. The storage component stores the camera when the drone lands.

[0008] The present invention is further configured such that a support base is fixedly connected to the top of the storage box, a dual-axis motor is fixedly connected to the bottom of the support base, and a rotating shaft is fixedly connected to the output end of the dual-axis motor.

[0009] The present invention is further configured such that a driving bevel gear is fixedly connected to one end of the rotating shaft, and a driven bevel gear is fixedly connected to the surface of the rotating rod, wherein the driving bevel gear meshes with the driven bevel gear.

[0010] The present invention is further configured such that a drive gear is fixedly connected to one side of the surface of the rotating shaft, and the drive gear meshes with the gear plate.

[0011] The present invention is further configured such that rotating grooves are provided on both sides of the storage box, and the surface of the support bar is rotatably connected to the inner cavity of the rotating groove.

[0012] The present invention is further configured such that the bottom of the storage box has a storage opening, and the surface of the base is slidably connected to the inner cavity of the storage opening.

[0013] The present invention is further configured such that slide bars are fixedly connected to both sides of the toothed plate, and limit strips are fixedly connected to both sides of the inner cavity of the storage box, and one side of the slide bar is slidably connected to the surface of the limit strip.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively solves the problem of traditional patrol drones' landing gear obstructing the camera's field of view through the coordinated design of the retraction and storage components. After the drone takes off, the retraction component can automatically fold the landing gear to make it flush with the bottom of the drone body, avoiding interference with the camera's shooting angle and ensuring the integrity and clarity of the patrol footage. At the same time, during landing, the storage component can retract the camera into the storage box cavity, preventing it from directly contacting the ground, reducing the risk of damage to the camera due to collision or friction, and extending the service life of the equipment.

[0016] 2. This utility model achieves rapid retraction and extension of the landing gear and intelligent storage of the camera through a mechanical structure driven by a dual-axis motor and bevel gear and toothed plate transmission. This design is not only compact and reliable in transmission, but also convenient to operate. It can automatically retract and extend key components without manual intervention, which greatly improves the efficiency and safety of patrol operations. In addition, the design of limiting strips and sliding strips in the storage box effectively ensures the operational stability of moving parts, enabling the drone to maintain good working performance under complex environmental conditions.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a support base 9 is fixedly connected to the top of the storage box 2. The support base 9 supports the dual-axis motor 10. The dual-axis motor 10 is fixedly connected to the bottom of the support base 9. A rotating shaft 11 is fixedly connected to the output end of the dual-axis motor 10. A driving bevel gear 12 is fixedly connected to one end of the rotating shaft 11. Both output ends of the dual-axis motor 10 are fixedly connected to the rotating shaft 11. A driven bevel gear 13 is fixedly connected to the surface of the rotating rod 3. The two pairs of driving bevel gears 12 and driven bevel gears 13 are mirror-distributed to drive the support bar 4 to rotate relative to or opposite to each other, so that the landing gear 5 can be supported or retracted. The driving bevel gear 12 meshes with the driven bevel gear 13. A drive gear 14 is fixedly connected to one side of the surface of the rotating shaft 11. The drive gear 14 meshes with the gear plate 6. 2. Rotating grooves 15 are provided on both sides. The rotating grooves 15 are "L" shaped to allow the support bar 4 to rotate at a sufficient angle so that the landing gear 5 can rotate to a specific angle.

One side of the sliding strip 17 is slidably connected to the surface of the limiting strip 18.

[0030] The working principle of this utility model is as follows: When the drone starts, the dual-axis motor 10 drives the rotating shaft 11 to rotate. Through the meshing transmission of the active bevel gear 12 and the driven bevel gear 13, the rotating rod 3 is driven to rotate, thereby causing the support bar 4 to drive the landing gear 5 to fold outward and unfold to both sides of the storage box 2, so as to avoid obstructing the shooting view of the camera 8. At the same time, the drive gear 14 on the rotating shaft 11 meshes with the toothed plate 6. The rotating shaft 11 drives the drive gear 14 to push the toothed plate 6 to slide along the limiting bar 18, so that the base 7 and the camera 8 extend from the storage port 16 and enter the working position. When landing, the dual-axis motor 10 rotates in the opposite direction, the landing gear 5 unfolds to support the body 1, and the toothed plate 6 retracts to put the camera 8 into the inner cavity of the storage box 2, avoiding contact with the ground, thus completing the entire process of automatic opening and closing and protection.
