Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV measurement and positioning device. Background Technology

[0002] When carrying out large-scale construction projects in mountainous areas, accurate surveying and positioning of the project area are crucial prerequisites for ensuring smooth construction progress and guaranteeing project quality and safety. Currently, drone technology, with its advantages of maneuverability and adaptability to complex terrain, is widely used in the preliminary surveying and positioning work of mountain construction. Through the high-precision sensors and positioning equipment carried by drones, three-dimensional terrain data and coordinate information of mountainous areas can be quickly acquired, providing important basis for subsequent construction planning and design.

[0003] However, mountain ecosystems are unique and complex, often home to numerous nationally protected plants, such as Chinese cypress and tree fern. These protected plants not only possess extremely high ecological value but also play an irreplaceable role in biodiversity conservation and maintaining ecosystem balance. During construction in mountainous areas, to avoid damaging these protected plants and ensure their normal growth and reproduction, current practices typically involve vegetation transplantation combined with growth regulators to promote root regeneration.

[0004] Existing drone-based surveying and positioning devices used in mountainous construction have significant design shortcomings, generally lacking effective marking capabilities for protected plants. In actual construction, because drone surveying and positioning systems cannot accurately mark and display information such as the location and distribution range of protected plants in real time, construction workers struggle to accurately identify and avoid these plants in complex terrain environments. This not only increases the risk of accidental damage to protected plants during construction but may also trigger a series of ecological protection and legal liability issues, causing considerable disruption to the smooth progress of mountainous construction projects.

[0005] Therefore, it is necessary to provide a new UAV measurement and positioning device to solve the above-mentioned technical problems. Application content

[0006] To address the aforementioned technical problems, this application proposes a UAV measurement and positioning device.

[0007] The technical solution adopted in this application is as follows: a drone measurement and positioning device, including a drone body, a camera installed at one end of the drone body, a mounting frame fixed at the bottom of the drone body, a rotating plate rotatably connected to the bottom of the mounting frame, a retractable protective shell connected to one end of the rotating plate, a circular plate slidably connected to the outer side of the protective shell, a square plate slidably connected to the inner side of the protective shell, and a rotating rod rotatably connected to one end of the mounting frame, the other end of the rotating rod being rotatably connected to the circular plate.

[0008] The protective shell has symmetrical storage boxes inside, and each storage box contains multiple sets of ribbon clips for marking. The ribbon clips are equipped with limiting components inside, and two symmetrical ribbon clips are locked together by the limiting components.

[0009] The protective casing also contains an adjustment mechanism for adjusting the tilt angle of the storage box;

[0010] The protective shell has symmetrically arranged push plates inside for pushing the ribbon clips, and a drive component for driving the push plates is also installed inside the protective shell.

[0011] Furthermore, a T-shaped shaft is rotatably connected to one end of the rotating plate, and a first torsion spring is fixedly connected to both ends of the T-shaped shaft. The opposite ends of the two first torsion springs are fixed to the interior of the rotating plate. One end of the T-shaped shaft passes through the protective shell and is fixedly connected to the square plate. A straight sliding groove is provided on the side of the square plate near the protective shell. A circular plate is rotatably connected to the middle of the T-shaped shaft. An arc sliding groove is provided on the side of the circular plate near the protective shell.

[0012] Furthermore, the protective shell is composed of a first protective plate, a second protective plate, a third protective plate, and a fourth protective plate that are slidably connected to each other. Each of the first, second, third, and fourth protective plates is fixedly connected with a sliding column, and the two ends of the sliding column slide in the straight sliding groove opened in the square plate and the arc sliding groove opened in the round plate, respectively.

[0013] Furthermore, the limiting component includes: a first locking block, a second locking block, a first spring, a third locking block, and a second spring.

The ribbon clip also has a third locking block slidably connected inside, and the third locking block engages with the second locking block. The ribbon clip also has a second spring fixedly connected inside, and one end of the second spring is fixedly connected to the third locking block. The ribbon clip also has a marker tape fixedly connected inside. In the initial state, the end of the third locking block away from the second spring does not contact the marker tape.

[0014] Furthermore, the adjusting components include: a fixed plate, a first connecting plate, a second torsion spring, a telescopic outer plate, a telescopic inner plate, a third spring, a second connecting plate, and a slide rail. A fixed plate is fixedly connected to the bottom of the square plate, and a first connecting plate is rotatably connected to the fixed plate. Second torsion springs are symmetrically fixedly connected to both ends of the fixed plate, with one end of each of the two opposing second torsion springs fixed to the first connecting plate. Telescopic outer plates are fixedly connected to the upper and lower sides of the first connecting plate, and a telescopic inner plate is slidably connected inside the telescopic outer plate. A third spring is also symmetrically fixedly connected inside the telescopic outer plate, with one end of the third spring fixed to the telescopic inner plate. Second connecting plates are symmetrically fixedly connected to the middle of both ends of the telescopic outer plate, and a slide rail is fixedly connected to one end of each second connecting plate. One side of the slide rail is fixedly connected to the storage box. Baffles are slidably connected to both ends of the storage box.

[0015] Furthermore, a fifth spring is fixedly connected inside the storage box, and a compression plate is also slidably connected inside the storage box, with the compression plate fixedly connected to the top of the fifth spring.

[0016] Furthermore, a corresponding rubber sleeve is fixedly connected to one end of the first, second, third, and fourth protection plates; a detection plate is fixedly connected to the opposite side of the third and fourth protection plates, and a pressure sensor is fixedly connected to the inner side of the detection plate.

One end of the push plate is fixedly connected to the transmission rod, the middle part of the transmission rod slides in the slide rail, and the inside of the slide rail is fixedly connected to the fourth spring, one end of the fourth spring being fixedly connected to the transmission rod.

[0018] Furthermore, the probe is made of a soft material.

[0019] Furthermore, a motor is fixedly connected inside the mounting bracket, a worm gear is fixedly connected to the output end of the motor, and a worm wheel is fixedly connected to the end of the rotating plate, with the worm wheel meshing with the worm gear.

[0020] The advantages of this application over the prior art are as follows:

[0021] Precise positioning markers:

[0022] This drone-based measurement and positioning device uses a camera and its own measurement and positioning function to accurately acquire the growth location information and geographical coordinates of protected plants. By utilizing a retractable protective shell, adjustable parts, drive parts, and limiting parts, it can accurately mark protected plants with ribbon clips. Compared with traditional devices, it effectively solves the problem of not being able to accurately mark and display information such as the location and distribution range of protected plants in real time, enabling construction personnel to accurately identify the location of protected plants in complex terrain and reducing the risk of accidental damage to protected plants during construction.

[0023] Improve the reliability and safety of harvesting operations:

[0024] This application utilizes a storage box, ribbon clip, and limiting components within the protective casing. When a drone approaches the target plant, a drive mechanism compresses the ribbon clip, engaging the first and second clips. Once the drone moves away, the marking tape (such as a fluorescent marking tape) is automatically released, creating a prominent physical mark on the plant's rootstock. This offline marking eliminates the need for transplanting personnel to carry additional electronic devices; the target location can be quickly identified visually. This overcomes the drawbacks of traditional online positioning, which relies on equipment, ensuring accurate positioning even in scenarios with no signal or equipment malfunction. This significantly improves the reliability and safety of transplanting operations.

[0025] Adapt flexibly to different scenarios:

[0026] The design of the rotating plate, T-shaped shaft, rotating rod, and protective shell allows the device to adapt to mountain walls at different angles. The adjustment mechanism can adjust the tilt angle of the storage box according to the actual situation of the plant roots and stems to ensure accurate marking by the ribbon clips. The drive mechanism realizes the snap-fit ​​and fixing of the ribbon clips and the ejection of the marking tape through simple mechanical transmission. The entire device can work flexibly in complex and ever-changing mountain environments to meet the marking needs of plants in different terrains and growth stages.

[0027] Dynamic angle adjustment:

[0028] After the telescopic inner plate is squeezed by the rootstock, the first connecting plate is rotated by the third spring, which drives the storage box to be parallel to the plant rootstock, ensuring that the ribbon clip releases the marking tape at the optimal angle, so that stable marking can be achieved even if the plant grows on an inclined mountain.

[0029] Save transplant time:

[0030] This application reduces the time transplanters need to search for plants by using drones for offline positioning and marking. This not only saves transplanting time and reduces the time transplanters spend hanging, but also further reduces the possibility of transplanting accidents and improves the safety of transplanting operations.

[0031] Plant protection and equipment:

[0032] The protective shell is composed of multiple sliding protective plates that can be unfolded and tightly fitted to the mountainside as needed. This protects plants from being scratched by the drone and prevents the drone and mountain winds from affecting the marking lines. The detection plate is made of soft material and has a pressure sensor on the inside, which allows the roots of the target plant to be aligned with the center of the protective shell, avoiding additional damage to the plant. At the same time, the various components of the device, through ingenious structural design and mechanical principles, such as the cooperation between the T-shaped shaft and the first torsion spring, and the dynamic change of the wing speed, ensure the stability of the drone during operation, reduce the impact on the surrounding environment of the plants, and also ensure the safety of the drone itself.

[0033] Improve construction efficiency and safety:

[0034] This device automates marking, eliminating the need for manual marking operations in mountainous areas, saving manpower and time costs, and improving construction efficiency. The precise marking function allows construction personnel to plan construction routes and schemes in advance, effectively avoiding protected plants and preventing ecological protection and legal liability issues caused by damage to protected plants. This ensures the smooth progress of mountain construction projects and improves the safety and standardization of construction. Attached Figure Description

[0051] like Figures 1 to 14 As shown, this application provides a drone measurement and positioning device, including: a drone body 1, with a camera 2 installed at one end of the drone body 1; an operator controls the drone body 1 to fly to a target area such as a mountain cliff, and takes pictures of the target area through the camera 2 installed at one end of the drone body 1 to obtain the growth location information of the protected plants.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 10 As shown, a mounting bracket 3 is fixed to the bottom of the drone body 1. A rotating plate 4 is rotatably connected to the bottom of the mounting bracket 3. One end of the rotating plate 4 is equipped with a retractable protective shell 5. The protective shell 5 can protect the plants from being scratched by the drone and can also prevent the drone and mountain winds from affecting the marking line. A circular plate 14 is slidably connected to the outer side of the protective shell 5, and a square plate 12 is slidably connected to the inner side of the protective shell 5. One end of a rotating rod 6 is rotatably connected to the mounting bracket 3, and the other end of the rotating rod 6 is rotatably connected to the circular plate 14. A storage box 7 is symmetrically arranged inside the protective shell 5. Multiple sets of ribbon clips 8 for marking are placed inside each storage box 7. Limiting components are installed inside the ribbon clips 8, and two symmetrical ribbon clips 8 can be locked together by the limiting components. An adjusting component for adjusting the tilt angle of the storage box 7 is also installed inside the protective shell 5. A push plate 9 for pushing the ribbon clips 8 is symmetrically arranged inside the protective shell 5, and a driving component for driving the push plate 9 is also installed inside the protective shell 5.

[0053] The operator controls the drone body 1 to fly to the target area such as mountain cliffs. The camera 2 installed at one end of the drone body 1 takes pictures of the target area and measures and locates it, and uploads the data to the Internet system. During the measurement and positioning process, the drone body 1 also obtains the growth location information of the protected plants, i.e. the target plants, through the camera 2. The drone body 1 uses its own measurement and positioning function to determine the precise geographical coordinates of the target plants.

[0054] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a T-shaped shaft 10 is rotatably connected to one end of the rotating plate 4. Both ends of the T-shaped shaft 10 are fixedly connected to first torsion springs 11, with the opposite ends of the two first torsion springs 11 fixed to the interior of the rotating plate 4. One end of the T-shaped shaft 10 passes through the protective shell 5 and is fixedly connected to a square plate 12. A straight groove 13 is provided on the side of the square plate 12 closest to the protective shell 5. A circular plate 14 is rotatably connected to the middle of the T-shaped shaft 10. An arc groove 15 is provided on the side of the circular plate 14 closest to the protective shell 5. Both the square plate 12 and the circular plate 14 are slidably connected to the protective shell 5. The other end of the rotating rod 6 is rotatably connected to the circular plate 14 via a universal ball joint. The protective shell 5 is composed of a first protective plate 16, a second protective plate 17, a third protective plate 18, and a fourth protective plate 19 that are slidably connected to each other. Each of the first protective plate 16, second protective plate 17, third protective plate 18, and fourth protective plate 19 has a sliding column 50 fixedly connected to it. The two ends of the sliding column 50 slide within the straight sliding groove 13 opened in the square plate 12 and the arc sliding groove 15 opened in the round plate 14, respectively. A motor 45 is fixedly connected inside the mounting frame 3. A worm gear 46 is fixedly connected to the output end of the motor 45. A worm wheel 47 is fixedly connected to the end of the rotating plate 4, and the worm wheel 47 meshes with the worm gear 46.

[0055] The drone body 1 gradually approaches the target plant to be marked, and the camera 2 initially confirms that the middle part of the protective shell 5 can be aligned with the rootstock of the target plant after the rotating plate 4 is rotated 90 degrees. Then, in preparation for offline marking, the drone body 1 rotates horizontally 90 degrees in place, starting the motor 45. The worm gear 46 at the output end of the motor 45 rotates, driving the worm wheel 47 fixed to the end of the rotating plate 4 to rotate, thereby causing the rotating plate 4 to rotate 90 degrees around the bottom of the mounting frame 3. As the rotating plate 4 rotates, the T-shaped shaft 10 drives the square plate 12 to rotate under the action of the two first torsion springs 11. Since the rotating rod 6 is rotatably connected to the round plate 14 through the universal ball, the rotating rod 6 will drive the round plate 14 to rotate during the rotation of the rotating plate 4. The sliding columns 50 on the first protective plate 16, the second protective plate 17, the third protective plate 18, and the fourth protective plate 19 slide in the straight sliding groove 13 and the arc sliding groove 15, causing the protective shell 5 to unfold. When the protective shell 5 is close to the mountain wall, the T-shaped shaft 10 can rotate around the rotating plate 4, so that the protective shell 5 is closely attached to the mountain wall at different angles. When the protective shell 5 is disengaged from the mountain wall, the T-shaped shaft 10 will reset under the action of the two first torsion springs 11.

[0056] The total mass of the protective shell 5 and its internal structure is less than the mass of the drone body 1. Therefore, when the protective shell 5 rotates, the two wings on the top of the drone body 1 that are close to the protective shell 5 rotate at the same speed and gradually increase, while the two wings on the top of the drone body 1 that are far from the protective shell 5 rotate at the same speed and gradually decrease. This allows the drone body 1 to use the two wings close to the protective shell 5 as fulcrums and balance the gravity on both sides of the fulcrums through the two wings far from the protective shell 5, so that the drone body 1 can remain balanced in the air and levitate. When the protective shell 5 gradually approaches and contacts the target plants and mountain wall, the rotation speed of the wings also changes dynamically to maintain the movement and balance of the drone body 1.

[0057] like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, one end of the first protection plate 16, the second protection plate 17, the third protection plate 18 and the fourth protection plate 19 are all fixedly connected with corresponding rubber sleeves 37; a detection plate 43 is fixedly connected to the opposite side of the third protection plate 18 and the fourth protection plate 19. The detection plate 43 is made of soft material, and a pressure sensor 44 is fixedly connected to the inner side of the detection plate 43. The pressure sensor 44 is electrically connected to the control module on the UAV body 1.

[0058] As the drone body 1 gradually approaches the target plant, the roots of the target plant will first contact the detection plate 43 and apply pressure to the detection plate 43. The detection plate 43 transmits the signal to the control module on the drone body 1 through the pressure sensor 44. The drone body 1 will then move towards the pressure sensor 44 that is transmitting the signal, so that the roots of the target plant are aligned with the center of the protective shell 5.

[0059] like Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12As shown, the adjusting components include: a fixed plate 25, a first connecting plate 26, a second torsion spring 27, a telescopic outer plate 28, a telescopic inner plate 29, a third spring 30, a second connecting plate 31, and a slide rail 32. The bottom of the square plate 12 is fixedly connected to the fixed plate 25, and the first connecting plate 26 is rotatably connected to the fixed plate 25. The two ends of the fixed plate 25 are symmetrically fixedly connected to the second torsion springs 27, and the opposite ends of the two second torsion springs 27 are both fixed to the first connecting plate 26. The upper and lower sides of the first connecting plate 26 are both fixedly connected to the telescopic outer plate 28, and the telescopic inner plate 29 is slidably connected inside the telescopic outer plate 28. The inside of the telescopic outer plate 28 is also symmetrically fixedly connected to the third spring 30, one end of which is connected to the telescopic inner plate 39. The inner plate 29 is fixed; the two ends of the telescopic outer plate 28 are symmetrically and fixedly connected to the middle of the second connecting plate 31, one end of the second connecting plate 31 is fixedly connected to the slide rail 32, and one side of the slide rail 32 is fixedly connected to the storage box 7; both ends of the storage box 7 are slidably connected to the baffles 39, and the two baffles 39 inside the same storage box 7 are fixedly connected to the opposite side of the connecting rods 40, and the opposite ends of the two connecting rods 40 are rotatably connected to the push rods 41; the top of the telescopic inner plate 29 is symmetrically and fixedly connected to the push block 42, and the push block 42 is rotatably connected to the push rod 41; the storage box 7 is fixedly connected to the inside of the fifth spring 49, and the storage box 7 is also slidably connected to the inside of the fifth spring 49.

[0060] The target plant roots will contact the telescopic inner plate 29. The telescopic inner plate 29 will slide into the telescopic outer plate 28 and compress the third spring 30 under the pressure of the target plant roots. The third spring 30 has a tendency to return to its original position. The third spring 30, which is subjected to greater compression force, will push the telescopic outer plate 28 connected to it to compress the first connecting plate 26. The first connecting plate 26 will rotate under the force, so that both telescopic inner plates 29 are in close contact with the target plant roots. At the same time, during the rotation of the first connecting plate 26, it will drive the slide rail 32 to rotate through the second connecting plate 31. The slide rail 32 will drive the storage box 7 fixedly connected to it to rotate until the plane of the ribbon clip 8 in the storage box 7 is perpendicular to the plane of the target plant roots, so that the two clips 8 can be put on the target plant roots later.

[0061] like Figure 7 , Figure 8 , Figure 9As shown, the driving components include: a driving rod 33, a lever 34, a transmission rod 35, and a fourth spring 36. One end of the third protection plate 18 and the fourth protection plate 19 are slidably connected to the driving rod 33, and one end of the driving rod 33 is inserted into the corresponding rubber sleeve 37 and fixedly connected to the rubber sleeve 37. The lever 34 is rotatably connected to the opposite side of the third protection plate 18 and the fourth protection plate 19. One end of the push plate 9 is fixedly connected to the transmission rod 35, and the middle part of the transmission rod 35 slides in the slide rail 32. The fourth spring 36 is fixedly connected inside the slide rail 32, and one end of the fourth spring 36 is fixedly connected to the transmission rod 35.

[0062] During the rotation of the slide rail 32, the push plate 9 will also rotate synchronously through the transmission rod 35 that slides inside the slide rail 32, ensuring that the relative position of the push plate 9 and the storage box 7 remains unchanged. During the process of the telescopic inner plate 29 being squeezed, the push block 42 fixed at the top of the telescopic inner plate 29 will move along with it. The push block 42 drives the connecting rod 40 to rise along the storage box 7 through the push rod 41. The connecting rod 40 drives the baffle 39 to move synchronously and expose the ribbon clip 8 at the bottom of the storage box 7. The fifth spring 49 will squeeze the ribbon clip 8 through the squeezing plate 48, so that the ribbon clip 8 is always in a compacted state inside the storage box 7.

[0063] After the protective shell 5 is pressed against the mountain wall, the drone body 1 continues to approach the mountain wall. The protective shell 5 and the mountain wall squeeze and compress the rubber sleeve 37. After the rubber sleeve 37 is deformed by force, the drive rod 33 inside is squeezed and slides to the inside of the protective shell 5. The drive rod 33 squeezes the lever 34. The lever 34 rotates around its rotational connection with the protective shell 5. During the rotation, the lever 34 pushes the transmission rod 35. The transmission rod 35 pushes the push plate 9 and squeezes the fourth spring 36. The push plate 9 pushes the ribbon clips 8 closer to each other. The ribbon clips 8 are locked in place by the limiting component.

[0064] like Figure 12 , Figure 13 As shown, the limiting components include: a first locking block 20, a second locking block 21, a first spring 22, a third locking block 23, and a second spring 24. One end of the ribbon clip 8 is fixedly connected to the first locking block 20, and the other end of the ribbon clip 8 is slidably connected to the second locking block 21. The first spring 22 is fixedly connected between the second locking block 21 and the ribbon clip 8. The third locking block 23 is also slidably connected inside the ribbon clip 8, and the third locking block 23 engages with the second locking block 21. The second spring 24 is fixedly connected inside the ribbon clip 8, and one end of the second spring 24 is fixedly connected to the third locking block 23. A marking tape 38 is also fixedly connected inside the ribbon clip 8, and the end of the third locking block 23 away from the second spring 24 does not contact the marking tape 38.

[0065] Under the pressure of the two push plates 9, the two ribbon clips 8 approach each other. The first locking block 20 of the ribbon clip 8 is inserted into the other ribbon clip 8 and engages with the second locking block 21 of the other ribbon clip 8. During the insertion process, the first locking block 20 will first squeeze the second locking block 21. The second locking block 21 squeezes the first spring 22 and releases the engagement between the second locking block 21 and the third locking block 23. The third locking block 23 is pushed out by the second spring 24 and comes into contact with the marking tape 38. At this time, because of the pressure of the push plates 9 on the ribbon clips 8, the marking tape 38 cannot be pushed out by the third locking block 23. When the first locking block 20 is fully inserted into the other ribbon clip 8, the first spring 22 resets and pushes the second locking block 21 to reset. The second locking block 21 engages with the first locking block 20. Since there is a gap between the third locking block 23 and the marking tape 38 in the initial state, the third locking block 23 is still in the state of being pushed out by the second spring 24. The second locking block 21 and the third locking block 23 are not engaged.

[0066] After the first locking block 20 and the second locking block 21 are engaged, the circle formed by the two ribbon clips 8 is placed on the root of the target plant. Then, the drone body 1 moves away from the mountain wall, the fourth spring 36 pushes the transmission rod 35 to reset, the transmission rod 35 pushes the lever 34 to rotate, and under the combined action of the transmission rod 35 and the lever 34, the drive rod 33 is reset, so that the rubber sleeve 37 is reset. At this time, the push plate 9 is reset along with the reset of the transmission rod 35, the marking tape 38 is no longer restricted by the push plate 9, and the second spring 24 pushes the third locking block 23 to push out the marking tape 38.
