Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) surveying and mapping technology, and in particular to a UAV-based surveying and mapping device. Background Technology

[0002] Advantages of UAV surveying: UAVs can complete large-scale farmland surveying tasks in a short time; no complicated preparation work or transportation of large equipment is required, only a suitable location is needed for takeoff; they can clearly distinguish crop types, growth status, signs of pests and diseases, and detailed information such as field ridges and ditches in farmland, providing accurate basis for farmland planning and management; and they can avoid personnel entering dangerous farmland areas, such as areas severely affected by pests and diseases, containing toxic and harmful substances, or areas with complex terrain that are prone to danger.

[0003] The mapping device for a drone mainly includes a mapping camera for mapping and a power and support structure for rotating the mapping camera. For example, patent CN210761307U discloses a drone that facilitates mapping, and patent CN217918456U discloses an airborne mapping device for a mapping drone. In order to support the drone body and protect the mapping camera during landing, the drone's legs are located on both sides of the mapping camera. However, when the mapping camera is rotated horizontally to the corresponding legs, the mapping camera can only perform mapping vertically downwards. If the mapping camera is tilted during mapping, it will be blocked by the legs, and the mapping camera blocked by the legs cannot effectively perform mapping work. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the rotating surveying camera being blocked by the outrigger in the prior art, and to provide a surveying device based on a drone.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drone-based mapping device includes:

[0007] Outriggers, supporting the underside of the drone body;

[0008] A rotating support connects the drone body to the outriggers;

[0009] The ring rotates around the rotating support;

[0010] Extension frame, connected to the outside of the swivel;

[0011] Mounting base, connected to the end of the extension frame;

[0012] The surveying camera is mounted on a rotating mounting base.

[0013] Furthermore, the rotating support includes two circular plates connected by a support column, and the opposite side edges of the circular plates are provided with annular grooves for the rotating ring to rotate.

[0014] Furthermore, a first motor is installed on the lower side of the rotating support. The output shaft of the first motor extends between the two circular plates and is connected to a drive gear. A gear ring is provided on the inner side of the rotating ring. Several intermediate gears mesh between the drive gear and the gear ring. The intermediate gears are rotatably installed between the two circular plates.

[0015] Furthermore, the inner end of the extension frame is connected to a mounting plate, which is bolted to the outside of the swivel; the extension frame is an inverted L-shaped rod structure.

[0016] Furthermore, the mounting base is an inverted U-shaped plate structure, and a second motor is mounted on the mounting base. The output shaft of the second motor is connected to the surveying camera.

[0017] Furthermore, there are two extension frames, which are symmetrically connected on both sides of the rotating ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention uses a rotating ring to drive the extension frame and the surveying camera to rotate. The rotating ring and the extension frame allow the surveying camera to move on the outer ring side of the support leg, avoiding the support leg from obstructing the surveying camera and ensuring that the surveying camera has a more complete and effective surveying range.

[0030] The present invention will be further described in detail below with reference to the embodiments.

[0031] Specific embodiments of the UAV-based surveying device provided by this utility model:

[0032] Please see Figure 1-5 The UAV-based mapping device includes legs 2, a rotating support 3, a swivel ring 4, an extension frame 5, a mounting base 6, and a mapping camera 7. The legs 2 are supported on the underside of the UAV body 1, which carries the mapping device in flight. The legs 2 of the mapping device are used to support other components of the mapping device and the UAV body 1.

[0033] The rotating support 3 is connected between the drone body 1 and the legs 2; the upper end of the legs 2 is connected to the lower side of the rotating support 3, and the legs 2 are four rod-shaped structures with horizontally bent lower ends, and the four legs 2 are evenly distributed around the circumference.

[0034] The rotating support 3 includes two circular plates 301, which are vertically aligned and horizontally arranged. There is a vertical gap between the two circular plates 301. Three circumferentially distributed support columns 302 are connected between the two circular plates 301. The support columns 302 are hollow structures to avoid excessive weight of the surveying device.

[0035] The rotating ring 4 rotates around the rotating support 3. The rotating ring 4 has a ring structure. The opposite side edges of the circular plate 301 are provided with annular grooves 303 for the rotating ring 4 to rotate. The upper and lower annular edges of the inner side of the rotating ring 4 slide along the inner side of the annular grooves 303 of the upper circular plate 301 and the inner side of the annular grooves 303 of the lower circular plate 301, respectively. The annular grooves 303 support and allow the rotating ring 4 to rotate and slide.

[0036] A first motor 8 is mounted on the lower side of the rotating support 3. The first motor 8 is located at the center between the upper ends of the four support legs 2. The output shaft of the first motor 8 extends between the two circular plates 301 and is connected to the drive gear 9. A gear ring 10 is provided on the inner side of the middle part of the rotating ring 4. Several intermediate gears 11 mesh between the drive gear 9 and the gear ring 10. The intermediate gears 11 are rotatably mounted between the two circular plates 301.

[0037] In this embodiment, both the drive gear 9 and the intermediate gear 11 are horizontally arranged and rotate horizontally. There are three intermediate gears 11, which are evenly distributed around the circumference. The three intermediate gears 11 are arranged alternately with the three support columns 302. Each of the three intermediate gears 11 has a vertical gear shaft, which passes through the intermediate gear 11. The end of the gear shaft of the intermediate gear 11 is rotatably connected to the circular plate 301.

[0038] The output shaft of the first motor 8 drives the drive gear 9 to rotate, which in turn causes the three intermediate gears 11 to rotate synchronously, thereby causing the gear ring 10 and the rotating ring 4 to rotate.

[0039] The extension frame 5 is connected to the outside of the rotating ring 4. The inner end of the extension frame 5, i.e., the end closest to the rotating ring 4, is connected to a mounting plate, which is bolted to the outside of the rotating ring 4. The extension frame 5 is an inverted L-shaped rod structure. In this embodiment, there are two extension frames 5, which are symmetrically connected to both sides of the rotating ring 4 to balance the forces on both sides of the rotating ring 4.

[0040] Mounting base 6 is connected to the end of extension frame 5; surveying camera 7 is rotatably mounted on mounting base 6. Mounting base 6 has an inverted U-shaped plate structure, and a second motor 12 is mounted on mounting base 6. The output shaft of the second motor 12 is connected to surveying camera 7, driving surveying camera 7 to rotate, thereby realizing the tilt angle adjustment of surveying camera 7; in the attached figure, surveying camera 7 is horizontal, and when conducting surveying work, the camera end of surveying camera 7 is tilted downwards or vertically downwards. Two surveying cameras 7 can perform comprehensive and thorough surveying.

[0041] The height of the mounting base 6 and the surveying camera 7 corresponds to the middle of the support leg 2. When the UAV body 1 lands, the ground will not touch the surveying camera 7. The horizontal distance from the rotating connection point of the mounting base 6 and the surveying camera 7 to the vertical center line of the UAV body 1 is greater than the horizontal distance from the lower end of the support leg 2 to the vertical center line of the UAV body 1. The camera end of the surveying camera 7 will not be blocked by the support leg 2 when tilted outward and downward or vertically downward, thus avoiding the phenomenon of the surveying camera 7 being blocked by the support leg 2 during the rotation surveying process.

[0042] In this embodiment, two second motors 12 and two surveying cameras 7 are used, meaning that the second motors 12 and surveying cameras 7 are installed on the mounting bases 6 on both sides of the rotating ring 4. The first motor 8 drives the rotating ring 4 to rotate 180 degrees back and forth, enabling the two surveying cameras 7 on both sides to achieve 360-degree omnidirectional surveying coverage. In some other embodiments, the surveying camera 7 and the second motor 12 are installed on the mounting base 6 on one side of the rotating ring 4, while the other side of the rotating ring 4 is not equipped with a surveying camera 7 and the second motor 12, but instead has a counterweight installed. This balances the weight on both sides of the rotating ring 4 and reduces costs, but the rotating ring 4 still needs to rotate 360 ​​degrees back and forth.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
