Description

Technical Field

[0001] The present application relates to the field of drone technology, and in particular to a drone measurement and positioning device. Background Art

[0002] When undertaking large-scale construction projects in mountainous areas, accurate measurement and positioning of the project area is crucial for ensuring smooth progress, quality, and safety. Currently, drone technology, with its advantages of flexibility and adaptability to complex terrain, has been widely used in the early stages of surveying and positioning in mountainous areas. The high-precision sensors and positioning equipment carried by drones can quickly acquire three-dimensional terrain data and coordinate information in mountainous areas, providing a crucial basis for subsequent construction planning and design.

[0003] However, mountainous ecological environments are unique and complex, often home to numerous nationally protected plants, such as Thuja thuja and Alsophila spinulosa. These protected plants not only possess extremely high ecological value but also play an irreplaceable role in biodiversity conservation and maintaining ecosystem balance. During mountain construction, to avoid damage to these protected plants and ensure their normal growth and reproduction, vegetation transplantation combined with growth regulators to promote root regeneration is currently a common protective measure.

[0004] Existing drone-based surveying and positioning systems used in mountain construction projects have significant design deficiencies, generally lacking effective marking capabilities for protected plants. During actual construction, the inability of drone-based surveying and positioning systems to accurately mark and present information such as the location and distribution of protected plants in real time makes it difficult for construction workers to accurately identify and avoid these plants in complex terrain. This not only increases the risk of accidental damage to protected plants during construction, but can also raise a series of ecological and legal liability issues, creating significant challenges for the smooth implementation of mountain construction projects.

[0005] Therefore, it is necessary to provide a new UAV measurement and positioning device to solve the above technical problems. Summary of the Invention

[0009] 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. The first protective plate, the second protective plate, the third protective plate and the fourth protective plate are all fixedly connected with sliding columns, and the two ends of the sliding columns slide in the straight sliding groove opened in the square plate and the arc sliding groove opened in the circular plate respectively.

[0010] Furthermore, the limiting component includes: a first clamping block, a second clamping block, a first spring, a third clamping block and a second spring, one end of the ribbon clip is fixedly connected to the first clamping block, the other end of the ribbon clip is slidably connected to the second clamping block, and the first spring is fixedly connected between the second clamping block and the ribbon clip; the interior of the ribbon clip is also slidably connected to the third clamping block, and the third clamping block is clamped with the second clamping block; the interior of the ribbon clip is fixedly connected to the second spring, and one end of the second spring is fixedly connected to the third clamping block; the interior of the ribbon clip is also fixedly connected to a marking tape, and in the initial state, the end of the third clamping block away from the second spring does not contact the marking tape.

[0011] The cam is fixedly mounted on said sliding panel and is provided with a pair of locks which are connected along said pivotal portion of said adjusting base, and said locks are connected along said pivotal portion to said sliding panel and said first, second locks being connected along said pivotal portion.

[0012] Furthermore, a fifth spring is fixedly connected to the interior of the storage box, and an extrusion plate is slidably connected to the interior of the storage box, and the extrusion plate is fixedly connected to the top of the fifth spring.

[0017] The beneficial effects of this application compared to the prior art are: Precise positioning mark: This drone measurement and positioning device uses a camera and its own measurement and positioning functions to accurately obtain the growth location information and geographic coordinates of protected plants. It then uses the coordination of structures such as a retractable protective shell, adjustment parts, drive parts, and limit parts to accurately mark protected plants using ribbon clips. Compared with traditional devices, this effectively solves the problem of being unable to accurately mark and present information such as the location and distribution range of protected plants in real time, enabling construction workers to accurately identify the location of protected plants in complex terrain and reduce the risk of accidental damage to protected plants during construction.

[0018] Improve the reliability and safety of picking operations: This application uses the design of a storage box, ribbon clip and limiter inside the protective shell. When the drone approaches the target protected plant, the driving part squeezes the ribbon clip to connect the first card block with the second card block. After the drone moves away, the marking tape (such as a fluorescent marking tape) is automatically released to form a striking physical mark at the root of the plant. This offline mark does not require transplant personnel to carry additional electronic equipment, and the target position can be quickly identified by vision alone, which solves the disadvantage of traditional online positioning relying on equipment, ensures accurate positioning in scenarios with no signal or equipment failure, and significantly improves the reliability and safety of transplant operations.

[0019] Flexible adaptation to different scenarios: The design of the rotating plate, T-shaped shaft, rotating rod and protective shell enables the device to adapt to mountain walls at different angles; the adjustment part can adjust the inclination angle of the storage box according to the actual situation of the plant roots, ensuring accurate marking of the ribbon clip; the driving part realizes the clamping and fixing of the ribbon clip and the ejection of the marking tape through simple mechanical transmission. The entire device can work flexibly in complex and changeable mountain environments, meeting the marking needs of protecting plants in different terrains and different growth states.

[0020] Dynamic angle adjustment: When the retractable inner plate is squeezed by the roots, the third spring pushes the first connecting plate to rotate, driving the storage box parallel to the plant roots, ensuring that the ribbon clip releases the marking tape at the optimal angle, and stable marking can be achieved even if the plants grow on a sloping mountain.

[0021] Save transplant time: This application reduces the time transplanters need to spend searching for plants through offline positioning and marking by drones, which not only saves transplanting time and reduces the hanging time of transplanters, but also further reduces the possibility of transplanting accidents and improves the safety of transplanting operations.

[0022] Protecting plants and devices: The protective shell is composed of multiple protective plates that are slidably connected. It can be unfolded according to actual conditions and fit tightly against the mountain wall, which not only protects the plants from being scratched by the drone, but also prevents the drone and mountain wind from affecting the offline markings; the detection plate is made of soft material and has a pressure sensor on the inside, which can align the roots of the target plant with the middle of the protective shell to avoid causing additional damage to the plants; at the same time, during operation, the various components of the device use clever structural design and mechanical principles, such as the coordination of the T-shaped shaft and the first torsion spring, and the dynamic change of the wing speed, to ensure the stability of the drone during operation, reduce the impact on the environment around the plants, and ensure the safety of the drone itself.

[0023] Improve construction efficiency and safety: The device realizes automatic marking, eliminating the need for manual risk-taking in mountainous areas, saving manpower and time costs and improving construction efficiency; the precise marking function enables construction personnel to plan construction routes and plans in advance, effectively avoiding protected plants, and avoiding ecological protection and legal liability issues caused by the destruction of protected plants, ensuring the smooth progress of mountain construction projects and improving the safety and standardization of construction.

[0026] like Figures 1 to 14 As shown, the present application provides a UAV measurement and positioning device, including: a UAV body 1, with a camera 2 installed at one end of the UAV body 1; the operator controls the UAV body 1 to fly to a target area such as a mountain cliff, and uses the camera 2 installed at one end of the UAV body 1 to shoot the target area to obtain the growth position information of the protected plants.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 、 Figure 10As shown, a mounting frame 3 is fixed to the bottom of the drone body 1. A rotating plate 4 is rotatably connected to the bottom of the mounting frame 3. A retractable protective cover 5 is installed at one end of the rotating plate 4. This protects the plants from being scratched by the drone and also prevents the drone and mountain wind from affecting the markings below the line. A circular plate 14 is slidably connected to the outer side of the protective cover 5, while a square plate 12 is slidably connected to the inner side of the protective cover 5. One end of a rotating rod 6 is rotatably connected to the mounting frame 3, and the other end of the rotating rod 6 is rotatably connected to the circular plate 14. Inside the protective cover 5, symmetrical storage boxes 7 are located. Each of these boxes contains multiple sets of ribbon clips 8 for marking. A stopper is installed inside the ribbon clips 8, allowing two symmetrical ribbon clips 8 to be locked together. Also installed inside the protective cover 5 is an adjustment member for adjusting the tilt angle of the storage box 7. Inside the protective cover 5, push plates 9 are symmetrically located for pushing the ribbon clips 8. A drive member for driving the push plates 9 is also installed inside the protective cover 5.

[0028] The operator controls the drone body 1 to fly to a target area such as a mountain cliff. 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 position 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 geographic coordinates of the target plants.

[0029] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, one end of the rotating plate 4 is rotatably connected to a T-shaped shaft 10. 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 defined on the side of the square plate 12 near the protective shell 5. The middle of the T-shaped shaft 10 is rotatably connected to a circular plate 14. An arc groove 15 is defined on the side of the circular plate 14 near 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 housing 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, which are slidably connected to each other. A slide post 50 is fixedly connected to each of the first, second, third, and fourth protective plates 16, 17, 18, and 19. The ends of the slide post 50 slide within the straight groove 13 defined in the square plate 12 and the arc groove 15 defined in the circular plate 14, respectively. A motor 45 is fixedly connected to the interior of the mounting frame 3. A worm 46 is fixedly connected to the output end of the motor 45. A worm gear 47 is fixedly connected to the end of the rotating plate 4, and the worm gear 47 meshes with the worm 46.

[0030] The drone body 1 gradually approaches the target plant to be marked, and preliminarily confirms through the camera 2 that the middle of the protective shell 5 can be aligned with the root of the target plant after the rotating plate 4 rotates 90 degrees. Then, in preparation for offline marking, the drone body 1 rotates horizontally 90 degrees on the spot, and the motor 45 is started. The worm 46 at the output end of the motor 45 rotates, driving the worm gear 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 circular plate 14 through the universal ball, the rotating rod 6 will drive the circular plate 14 to rotate during the rotation of the rotating plate 4. The sliding posts 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 slide groove 13 and the arc slide 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 fits tightly with the mountain wall at different angles. When the protective shell 5 loses contact with the mountain wall, the T-shaped shaft 10 will reset under the action of the two first torsion springs 11.

[0031] Among them, the total mass of the protective shell 5 and its internal structure is less than the mass of the drone body 1, so when the protective shell 5 rotates, the two wings on the top of the drone body 1 close to the protective shell 5 rotate at the same speed and gradually increase, and the two wings on the top of the drone body 1 away from the protective shell 5 rotate at the same speed and gradually decrease, so that the drone body 1 uses the two wings close to the protective shell 5 as the fulcrum, and balances the gravity on both sides of the fulcrum through the two wings away from the protective shell 5, so that the drone body 1 remains balanced in the air and can float in the air; when the protective shell 5 gradually approaches and contacts the target plants and mountain walls, the rotation speed of the wings also changes dynamically to maintain the movement and balance of the drone body 1.

[0032] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown, one end of the first protective plate 16, the second protective plate 17, the third protective plate 18 and the fourth protective plate 19 are fixedly connected to the corresponding rubber sleeve 37; the opposite sides of the third protective plate 18 and the fourth protective plate 19 are fixedly connected to the detection plate 43, the detection plate 43 is made of soft material, and the inner side of the detection plate 43 is fixedly connected to the pressure sensor 44, which is electrically connected to the control module on the drone body 1.

[0033] As the drone body 1 gradually approaches the target plant, the target plant roots will preferentially 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 move toward the pressure sensor 44 that transmits the signal, so that the target plant roots are aligned with the middle of the protective shell 5.

[0034] like Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 As shown, the adjusting member includes: 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 facing ends of the two second torsion springs 27 are fixed to the first connecting plate 26; the upper and lower sides of the first connecting plate 26 are fixedly connected to the telescopic outer plate 28, and the inner part of the telescopic outer plate 28 is slidably connected to the telescopic inner plate 29; the inner part of the telescopic outer plate 28 is also symmetrically fixedly connected to the third spring 30, and one end of the third spring 30 is fixedly connected to the telescopic The inner plate 29 is fixed; the second connecting plate 31 is symmetrically fixedly connected to the middle of both ends of the telescopic outer plate 28, 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 sides of the connecting rod 40, and the opposite ends of the two connecting rods 40 are rotatably connected to the push rod 41, and the top of the telescopic inner plate 29 is symmetrically fixedly connected to the push block 42, and the push block 42 is rotatably connected to the push rod 41; the inside of the storage box 7 is fixedly connected to the fifth spring 49, and the inside of the storage box 7 is also slidably connected to the extrusion plate 48, and the extrusion plate 48 is fixedly connected to the top of the fifth spring 49.

[0035] The target plant roots will contact the telescopic inner plate 29. The telescopic inner plate 29 will slide toward the inside of the telescopic outer plate 28 and squeeze the third spring 30 due to the squeezing of the target plant roots. The third spring 30 has a reset tendency. The third spring 30 with a large squeezing force will push the telescopic outer plate 28 connected to it to squeeze the first connecting plate 26. The first connecting plate 26 is forced to rotate, so that the two telescopic inner plates 29 are in close contact with the target plant roots. At the same time, the first connecting plate 26 will drive the slide rail 32 to rotate through the second connecting plate 31 during the rotation process, and the slide rail 32 will drive the storage box 7 fixed to it to rotate until the plane where the ribbon clip 8 in the storage box 7 is located is perpendicular to the plane where the target plant roots are located, so that the two clipped ribbon clips 8 can be put on the target plant roots in the later stage.

[0036] like Figure 7 、 Figure 8 、 Figure 9 As shown, the driving part includes: a driving rod 33, a lever 34, a transmission rod 35 and a fourth spring 36. One end of the third protective plate 18 and the fourth protective plate 19 are both 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 third protective plate 18 and the fourth protective plate 19 are both rotatably connected to the lever 34 on the opposite side; one end of the push plate 9 is fixedly connected to the transmission rod 35, the middle part of the transmission rod 35 slides in the slide rail 32, and the interior of the slide rail 32 is fixedly connected to the fourth spring 36, and one end of the fourth spring 36 is fixedly connected to the transmission rod 35.

[0037] During the rotation process, the slide rail 32 will also drive the push plate 9 to rotate synchronously through the transmission rod 35 sliding inside the slide rail 32, ensuring that the relative position of the push plate 9 and the storage box 7 remains unchanged. In the process of the telescopic inner plate 29 being squeezed, the push block 42 fixed on the top of the telescopic inner plate 29 will move along, and 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 in the storage box 7.

[0038] After the protective shell 5 is pressed against the mountain wall, the drone body 1 continues to approach the mountain wall, and the protective shell 5 and the mountain wall are squeezed and compressed. The rubber sleeve 37 is compressed. After the rubber sleeve 37 is deformed by the force, the driving rod 33 inside it is squeezed and slides to the inside of the protective shell 5. The driving rod 33 squeezes the lever 34, and the lever 34 rotates around the rotation connection between it and the protective shell 5. During the rotation, the lever 34 pushes the transmission rod 35, and the transmission rod 35 pushes the push plate 9 and squeezes the fourth spring 36. The push plate 9 pushes the ribbon clips 8 to move closer to each other, and the ribbon clips 8 are clamped and fixed by the limit piece.

[0039] like Figure 12 、 Figure 13 As shown, the limiting component includes: a first clamping block 20, a second clamping block 21, a first spring 22, a third clamping block 23 and a second spring 24. One end of the ribbon clip 8 is fixedly connected to the first clamping block 20, and the other end of the ribbon clip 8 is slidably connected to the second clamping block 21. The first spring 22 is fixedly connected between the second clamping block 21 and the ribbon clip 8; the interior of the ribbon clip 8 is also slidably connected to the third clamping block 23, and the third clamping block 23 is clamped with the second clamping block 21; the interior of the ribbon clip 8 is fixedly connected to the second spring 24, and one end of the second spring 24 is fixedly connected to the third clamping block 23; the interior of the ribbon clip 8 is also fixedly connected to the marking tape 38, and the end of the third clamping block 23 away from the second spring 24 does not contact the marking tape 38.

[0040] When the first clamping block 20 is fully inserted into the other ribbon clip 8, the first spring 22 resets and pushes the second clamping block 21 to reset, and the second clamping block 21 is clamped with the first clamping block 20. Since there is a gap between the third clamping block 23 and the marking tape 38 in the initial state, the third clamping block 23 is still in a state of being pushed out by the second spring 24, and the second clamping block 21 and the third clamping block 23 are not clamped.

[0041] After the first clamping block 20 and the second clamping block 21 are engaged, the circle formed by the two ribbon clips 8 is put on the root of the target plant, and then the drone body 1 moves away from the mountain wall, and the fourth spring 36 pushes the transmission rod 35 to reset, and the transmission rod 35 pushes the lever 34 to rotate. Under the joint action of the transmission rod 35 and the lever 34, the driving rod 33 is driven to reset, so that the rubber sleeve 37 is reset; at this time, the push plate 9 is reset as the transmission rod 35 is reset, and the marking belt 38 loses the restriction of the push plate 9. The second spring 24 pushes the marking belt 38 out by pushing the third clamping block 23. The marking belt 38 provides a conspicuous mark for the staff, which is convenient for the subsequent staff to transplant the plants.
