Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV specifically designed for multi-angle mapping. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. UAV aerial surveying is a powerful supplement to traditional aerial photogrammetry, featuring high mobility, efficiency, speed, precision, low operating costs, wide applicability, and short production cycles. It has broad prospects in basic surveying and mapping, land resource investigation and monitoring, land use dynamic monitoring, digital city construction, and emergency disaster relief surveying data acquisition. Existing technologies, such as the multi-angle surveying UAV disclosed in announcement number CN213892956U, allow for camera extension and retraction, and arbitrary adjustment in both horizontal and vertical directions, reducing the difficulty of operating UAV photography. However, the aforementioned existing technologies have the following shortcomings: When using these surveying UAVs, the camera is fixedly mounted on the bottom of the UAV. During UAV surveying operations, the camera requires regular maintenance (such as lens cleaning, sensor calibration, and battery replacement) or repair and replacement in case of equipment failure. The fixed installation design makes camera disassembly extremely difficult, severely impacting maintenance efficiency. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a multi-angle surveying drone. By closing the cover plate, the fixed top rod automatically pushes the clamping strips to complete the clamping, eliminating the need for manual bolt adjustment and calibration. Disassembly only requires removing the clamping plate screws, pulling out the clamping plate and pulling the cover plate. A spring drives the clamping strips to reset and release the clamp, allowing for quick camera replacement and maintenance, reducing downtime and ensuring work progress. The rectangular clamping frame formed by clamping strip one and clamping strip two engages with the conical clamp for double fixation, fully enclosing the rotating limit plate to resist side-flight centrifugal force and takeoff and landing impact force, preventing horizontal deviation and ensuring the stability of the camera assembly. The servo motor and transmission rod work together, with the motor driving the transmission rod to rotate, which in turn drives the transmission sleeve rod, camera, and rotating limit plate to rotate via a spline, achieving continuous 360° horizontal rotation of the camera, meeting the needs of large-area panoramic or detailed surveying in specific directions.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-angle surveying drone, including a drone body and a multi-angle camera body disposed below the drone body; a fixing sleeve is fixedly installed on the bottom frame of the drone body by a bolt; a clamping strip is symmetrically arranged inside the fixing sleeve; a transmission sleeve rod is provided on one side of the fixing sleeve; one end of the transmission sleeve rod is connected to the multi-angle camera body by a bolt; a rotation limiting plate is rotatably connected to the outer surface of the transmission sleeve rod; two clamping strips are respectively used to clamp on both sides of the rotation limiting plate; sliders are fixed on both ends of the two clamping strips; a sliding groove adapted to the slider is opened on the inner side wall of the fixing sleeve; the clamping strips are slidably connected to the inner side of the fixing sleeve through the slider and the sliding groove.

[0005] By adopting the above technical solutions, the bolted connection between the fixing sleeve and the drone body allows for individual replacement of the fixing sleeve in case of damage, reducing maintenance costs; the bolted connection between the camera and the transmission sleeve allows for independent repair of the camera without disassembling the transmission structure when it malfunctions, and the symmetrical clamping of the rotating limit plate on both sides prevents it from shifting, ensuring the coaxiality of the transmission sleeve and the fixing sleeve, thereby ensuring stable camera rotation and preventing image blurring caused by eccentric rotation.

[0006] Furthermore, a conical clamp is fixed to one of the adjacent surfaces of the two clamping strips, and a slot is provided on one of the rotating limiting plates that contacts the two clamping strips.

[0007] By adopting the above technical solution, the conical structure of the cone clamp and the groove of the card slot complement each other and engage, which greatly improves the friction compared with the flat clamping, avoids the relative sliding of the rotating limit plate and the clamping strip under strong vibration, and improves the stability of installation.

[0008] Furthermore, two clamping strips are symmetrically arranged between the two clamping strips one, and the two clamping strips one and two clamping strips two together form a rectangular frame structure for clamping the rotation limiting plate. A C-shaped clamping plate for clamping the rotation limiting plate is fixed on one side of the clamping strips two.

[0009] By adopting the above technical solution, clamping strip one and clamping strip two form a rectangular frame, which realizes four-way full-wrap clamping of the rotation limiting plate. Compared with only left and right clamping, it can limit its displacement in all directions on the horizontal plane, ensuring that the rotation limiting plate is always located in the center of the fixed sleeve, providing stable support for the camera.

[0010] Furthermore, both ends of the two clamping strips one and the two clamping strips two are wedge-shaped, and the inclined surface of the end of the clamping strip two is slidably connected to the inclined surface of the end of the clamping strip one.

[0011] By adopting the above technical solution, when the clamping strip 1 moves relative to the clamping strip 2, the inclined surface at its end will generate a squeezing force on the inclined surface of the clamping strip 2, converting the movement of the clamping strip 1 into the synchronous movement of the clamping strip 2, thereby realizing the synchronous clamping action of the four clamping strips, two clamping strips 2, and two clamping strips 1.

[0012] Furthermore, a strip-shaped groove is formed on the surface of the second clamping strip, and a sliding plate is slidably connected in the strip-shaped groove. The other end of the sliding plate is slidably connected in a blind groove formed on the surface of the first clamping strip, and abuts against one end of a spring set in the blind groove formed on the surface of the first clamping strip.

[0013] By adopting the above technical solution, the connecting slide slides in the strip groove and the blind groove of the first clamping strip, providing dual guidance for the relative movement of the first clamping strip and the second clamping strip, preventing misalignment during movement, while the spring can also provide a reset function.

[0014] Furthermore, a cover plate is provided at the bottom opening of the fixed sleeve, the transmission sleeve rod is rotatably connected to the surface of the cover plate, and L-shaped slides are fixedly installed on the surfaces of the two clamping strips. A fixed top rod is fixedly installed on the surface of the cover plate. When the fixed top rod covers the bottom opening of the fixed sleeve, the fixed top rod pushes the clamping strip, causing the two clamping strips to move relative to each other and clamp and limit the rotation limit plate.

[0015] By adopting the above technical solution, the clamping is triggered synchronously by the closing action of the cover plate, eliminating the need for additional operations and simplifying the camera installation process. Operators only need to close the cover plate and fix the top rod to automatically push the clamping strip to complete the clamping.

[0016] Furthermore, positioning rods are fixed at the corners of the cover plate surface, and positioning slots that are compatible with the positioning rods are provided on the bottom end face of the fixing sleeve.

[0017] By adopting the above technical solution, the process of inserting the positioning rod into the positioning slot provides a closing guide for the cover plate, avoiding misalignment during closing by the operator, which would cause the fixed top rod to fail to align with the L-shaped slide.

[0018] Furthermore, a retaining plate is fixedly installed on the surface of the cover plate, and a retaining plate groove adapted to the retaining plate is opened on the side of the retaining sleeve. The retaining plate is inserted into the retaining plate groove and fixed by screws.

[0019] By adopting the above technical solution, the cooperation between the card plate and the card plate slot achieves mechanical locking between the cover plate and the fixing sleeve. Further reinforcement with screws can completely prevent the cover plate from falling off during the flight of the drone.

[0020] Furthermore, a servo motor is installed on the inner top surface of the fixed sleeve, and a transmission rod is fixedly installed at the output end of the servo motor. The transmission rod is slidably connected inside the transmission sleeve rod along its own axial direction.

[0021] By adopting the above technical solution, the servo motor (working in conjunction with the transmission rod, the transmission rod being slidably connected to the transmission sleeve rod via splines or keyways) adjusts the horizontal angle. The flight control module instructs the servo motor to drive the transmission rod to rotate, thereby causing the transmission sleeve rod, camera, and rotation limit plate to rotate together, achieving continuous 360° horizontal rotation of the camera. This meets the needs of large-area panoramic or detailed mapping in specific directions. In summary, this utility model has the following beneficial effects:

[0022] 1. During installation, simply place the camera assembly into the mounting sleeve and close the cover plate. The clamping strip will be automatically pushed by the fixing rod to complete the clamping, without the need for manual adjustment of bolts or calibration of position. During disassembly, simply remove the clamping plate fixing screws, pull out the clamping plate, and pull the cover plate. The spring will automatically reset the clamping strip to release the clamping, allowing the camera assembly to be directly removed. Operators can quickly complete camera replacement or maintenance, effectively reducing equipment downtime and ensuring work progress.

[0023] 2. A dual fixing structure of rectangular frame clamping and conical clamp engagement achieves high-strength and stable installation of the camera assembly. Clamping strip one and clamping strip two together form a rectangular frame, providing full-wrap clamping to the rotation limit plate from four directions: left, right, front, and back. This can resist the centrifugal force during UAV side flight and the impact force during takeoff and landing, preventing the rotation limit plate from shifting horizontally. 3. Through the coordinated action of the servo motor and the transmission rod, multi-angle adjustment of the camera is achieved. The servo motor drives the transmission rod to rotate around its own axis. The transmission rod drives the transmission sleeve rod to rotate synchronously through spline transmission, thereby driving the multi-angle camera body and the rotation limit plate to rotate together. This allows for continuous 360° horizontal rotation of the multi-angle camera body, meeting the needs of large-area panoramic mapping or detailed mapping in specific directions.

Detailed Implementation

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figures 1-8 As shown in the figure, this application discloses a multi-angle surveying drone, including a drone body 1 and a multi-angle camera body 2 disposed below the drone body 1; a fixing sleeve 3 is fixedly installed on the bottom frame of the drone body 1 by a bolt, and clamping strips 9 are symmetrically arranged inside the fixing sleeve 3. A transmission sleeve rod 6 is provided on one side of the fixing sleeve 3. One end of the transmission sleeve rod 6 is connected to the multi-angle camera body 2 by a bolt. A rotation limit plate 7 is rotatably connected to the outer surface of the transmission sleeve rod 6. Two clamping strips 9 are respectively used to clamp on both sides of the rotation limit plate 7. A slider 10 is fixed to both ends of the two clamping strips 9. A sliding groove 11 adapted to the slider 10 is opened on the inner side wall of the fixing sleeve 3. The clamping strips 9 are slidably connected to the inner side of the fixing sleeve 3 through the slider 10 and the sliding groove 11.

[0034] The fixing sleeve 3 is connected to the bottom frame of the UAV body 1 by bolts. Compared with non-removable structures such as welding, the fixing sleeve 3 can be disassembled and replaced separately when it is damaged, reducing maintenance costs. The bolt connection realizes the detachable fixing of the multi-angle camera body 2 and the transmission sleeve rod 6. If the camera malfunctions, the camera can be disassembled and repaired separately without disassembling the entire transmission structure. Symmetrical clamping forces are applied from both sides of the rotation limit plate 7 to avoid the rotation limit plate 7 from being offset due to unilateral clamping, ensuring the coaxiality of the transmission sleeve rod 6 and the fixing sleeve 3, thereby ensuring the stability of the camera during rotation and preventing image blurring caused by eccentric rotation.

[0035] Furthermore, a cone clamp 17 is fixed on the adjacent side surface of the two clamping strips 9, and a slot 8 is provided on the side of the rotating limiting plate 7 that contacts the two clamping strips 9.

[0036] The tapered structure of the tapered clamp 17 and the groove of the slot 8 form a complementary engagement, which greatly improves the clamping friction compared to planar contact clamping. This prevents relative sliding between the rotation limit plate 7 and the clamping strip 9 due to strong vibrations during flight. At the same time, the tapered structure can limit the up and down movement of the rotation limit plate 7 along the axis of the transmission sleeve rod 6, achieving axial limiting and further improving the stability of the camera installation.

[0037] Furthermore, two clamping strips 12 are symmetrically arranged between the two clamping strips 1 and 9. The two clamping strips 1 and 2 clamping strips 12 together form a rectangular frame structure for clamping the rotation limiting plate 7. A C-shaped clamping plate 13 for clamping the rotation limiting plate 7 is fixed on one side of the clamping strip 2 12.

[0038] The clamping strip 9 and clamping strip 12 form a rectangular frame, which fully encloses the rotation limiting plate 7 from four directions. Compared with clamping only on the left and right sides, it can limit the rotation limiting plate 7 from shifting in all directions on the horizontal plane (such as the centrifugal force when the drone flies sideways, which may cause the rotation limiting plate 7 to shift back and forth), ensuring that the rotation limiting plate 7 is always in the center position of the fixed sleeve 3, providing a stable support foundation for the camera.

[0039] Furthermore, both ends of the two clamping strips 1-9 and the two clamping strips 2-12 are wedge-shaped, and the inclined surface of the end of the clamping strip 2-12 is slidably connected to the inclined surface of the end of the clamping strip 1-9.

[0040] When clamping strip 19 moves relative to each other, the inclined surface at its end will exert a squeezing and pushing force on the inclined surface of clamping strip 212, converting the movement of clamping strip 19 into the synchronous movement of clamping strip 212, thus realizing the synchronous clamping action of the four clamping strips, two clamping strips 212, and two clamping strips 19.

[0041] Furthermore, a strip groove 14 is provided on the surface of the second clamping strip 12, and a sliding plate 15 is slidably connected in the strip groove 14. The other end of the sliding plate 15 is slidably connected in a blind groove provided on the surface of the first clamping strip 9, and abuts against one end of a spring 16 provided in the blind groove provided on the surface of the first clamping strip 9.

[0042] The connecting slide plate 15 slides simultaneously within the blind groove of the strip groove 14 and the first clamping strip 9, providing dual guidance for the relative movement of the first clamping strip 9 and the second clamping strip 12, preventing misalignment during movement. At the same time, the spring 16 can also provide a reset function.

[0043] Furthermore, a cover plate 18 is provided at the bottom opening of the fixed sleeve 3, and the transmission sleeve rod 6 is rotatably connected to the surface of the cover plate 18. L-shaped slides 22 are fixedly installed on the surfaces of the two clamping strips 9, and a fixed top rod 21 is fixedly installed on the surface of the cover plate 18. When the fixed top rod 21 covers the bottom opening of the fixed sleeve 3, the fixed top rod 21 pushes the clamping strips 9, causing the two clamping strips 9 to move relative to each other and clamp and limit the rotation limit plate 7.

[0044] The clamping action is triggered synchronously by the closing action of the cover plate 18, which simplifies the camera installation process without additional operation. The operator only needs to close the cover plate 18 and fix the top rod 21 to automatically push the clamping bar 9 to complete the clamping.

[0045] Furthermore, positioning rods 23 are fixed at the corners of the cover plate 18, and positioning slots 24 that are compatible with the positioning rods 23 are provided on the bottom end face of the fixing sleeve 3.

[0046] The process of inserting the positioning rod 23 into the positioning slot 24 provides a closing guide for the cover plate 18, preventing misalignment during closing by the operator, which would cause the fixed top rod 21 to fail to align with the L-shaped slide block 22.

[0047] Furthermore, a card plate 19 is fixedly installed on the surface of the cover plate 18, and a card plate groove 20 adapted to the card plate 19 is opened on the side of the fixing sleeve 3. The card plate 19 is inserted into the card plate groove 20 and fixed by screws.

[0048] The cooperation between the card plate 19 and the card plate slot 20 achieves mechanical locking between the cover plate 18 and the fixing sleeve 3, and is further reinforced by screws, which can completely prevent the cover plate 18 from falling off during the flight of the drone.

[0049] Furthermore, a servo motor 4 is installed on the inner top surface of the fixed sleeve 3, and a transmission rod 5 is fixedly installed on the output end of the servo motor 4. The transmission rod 5 is slidably connected to the transmission sleeve rod 6 along its own axis.

[0050] Through the coordinated action of servo motor 4 and transmission rod 5, multi-angle adjustment of the camera is achieved. The servo motor 4, which is installed on the top surface inside the fixed sleeve 3, has its output end fixedly connected to the transmission rod 5. The transmission rod 5 is slidably connected to the transmission sleeve 6 along its own axis. The transmission rod 5 and the transmission sleeve 6 are connected by splines or keyways to ensure that they can rotate synchronously but allow axial relative sliding. When it is necessary to adjust the horizontal angle of the multi-angle camera body 2, the flight control module sends a command to the servo motor 4. The servo motor 4 drives the transmission rod 5 to rotate around its own axis. The transmission rod 5 drives the transmission sleeve 6 to rotate synchronously through spline transmission, thereby driving the multi-angle camera body 2 and the rotation limit plate 7 to rotate together. When the rotation limit plate 7 rotates around the axis of the transmission sleeve 6, the clamping strip 1 9 and clamping strip 2 12 only restrict its translation and do not affect its rotation. This allows the multi-angle camera body 2 to rotate continuously 360° in the horizontal direction, meeting the needs of large-area panoramic mapping or detailed mapping in a specific direction.

[0051] The working principle of this utility model is as follows:

[0052] Before the drone is put into operation, the fixing sleeve 3 is first tightly fixed to the bottom frame of the drone body 1 with bolts to ensure that there is no relative looseness between the fixing sleeve 3 and the drone body 1, so as to provide a stable support base for the subsequent installation of the camera and avoid the camera shaking due to the displacement of the fixing sleeve 3 during flight.

[0053] Subsequently, one end of the transmission sleeve rod 6 is fixed to the top of the multi-angle camera body 2 by bolts. Both ends of the clamping strip 9 are fixed with sliders 10, and the inner side wall of the fixed sleeve 3 is provided with a groove 11 that matches the slider 10. The slider 10 can slide back and forth along the length of the groove 11. This structure provides precise guidance for the movement of the clamping strip 9, ensuring that the two clamping strips 9 always move in a direction parallel to the central axis of the fixed sleeve 3, avoiding misalignment due to offset. In the initial state, the two clamping strips 9 are in a position far apart from each other, leaving enough space for the rotating limiting plate 7 to be placed into the fixed sleeve 3.

[0054] Cover the bottom opening of the fixing sleeve 3 with the cover plate 18, and insert the positioning rod 23 at the corner of the surface of the cover plate 18 into the positioning slot 24 on the bottom end face of the fixing sleeve 3 to achieve the initial positioning of the cover plate 18 and the fixing sleeve 3, ensuring that the center of the cover plate 18 is coaxial with the center of the fixing sleeve 3, and avoiding uneven clamping force caused by the cover plate offset.

[0055] As the cover plate 18 closes, the fixed top rod 21 pushes the bottom of the clamping strip 9 upward. Since the clamping strip 9 is restricted by the guide of the slider 10 and the slide groove 11, it can only move in the horizontal direction. The upward pushing force of the fixed top rod 21 is converted into the relative moving force of the two clamping strips 9, which causes the two clamping strips 9 to gradually approach each other until their inner surfaces contact the two sides of the rotating limiting plate 7. When the two clamping strips 9 move relative to each other and contact the rotating limiting plate 7, the further cooperative structure realizes the initial limiting of the installation of the multi-angle camera body 2.

[0056] The conical clamps 17 fixed on the adjacent surfaces of the two clamping strips 9 fit perfectly into the slots 8 opened on both sides of the rotating limiting plate 7. The conical structure of the clamp 17 complements the groove shape of the slot 8, which not only increases the contact area between the clamping strips 9 and the rotating limiting plate 7, but also prevents the rotating limiting plate 7 from moving up and down along the axis of the transmission sleeve rod 6 through the conical engagement, thus achieving axial limiting.

[0057] Two clamping strips 12 are symmetrically arranged between the two clamping strips 1-9. Their ends are wedge-shaped and their inclined surfaces are slidably connected to the inclined surfaces at the ends of the clamping strips 1-9. When the clamping strips 1-9 move relative to each other, the two clamping strips 12 are pushed towards the rotation limiting plate 7 by the squeezing action of the inclined surfaces until the C-shaped clamping plate 13 fixed on one side of the clamping strip 12 is tightly attached to the other two sides of the rotation limiting plate 7. At this time, the clamping strips 1-9 and the clamping strips 12 form a rectangular frame structure, which fully encloses the rotation limiting plate 7 from four directions, preventing the rotation limiting plate 7 from shifting horizontally due to vibration during flight.

[0058] After clamping is completed, the clamping plate 19 is fixed to the fixing sleeve 3 with screws. This step uses a mechanical locking structure to prevent the cover plate 18 from falling off due to vibration during the flight of the drone. At the same time, it further ensures the continuous pushing force of the fixing top rod 21 on the clamping plate strip 9 and maintains the stability of the clamping structure.

[0059] After the multi-angle camera body 2 is fixed, the multi-angle adjustment of the camera is realized through the coordinated action of the servo motor 4 and the transmission rod 5. The servo motor 4, which is installed on the top surface inside the fixed sleeve 3, is fixedly connected to the transmission rod 5 at its output end. The transmission rod 5 is slidably connected to the transmission sleeve 6 along its own axis (the transmission rod 5 and the transmission sleeve 6 are fitted with splines or keyways to ensure that they can rotate synchronously but allow relative axial sliding). When it is necessary to adjust the horizontal angle of the multi-angle camera body 2, the flight control module sends a command to the servo motor 4. The servo motor 4 drives the transmission rod 5 to rotate around its own axis. The transmission rod 5 drives the transmission sleeve 6 to rotate synchronously through spline transmission, thereby driving the multi-angle camera body 2 and the rotation limit plate 7 to rotate together (when the rotation limit plate 7 rotates around the axis of the transmission sleeve 6, the clamping strip 9 and the clamping strip 12 only restrict its translation and do not affect its rotation). The multi-angle camera body 2 can be continuously rotated 360° in the horizontal direction, which meets the needs of large-area panoramic mapping or fine mapping in specific directions. There is no need to adjust the flight attitude of the UAV body 1, which greatly improves the mapping efficiency.

[0060] When maintenance of the multi-angle camera body 2 is required, such as lens cleaning, sensor calibration, or replacement of different types of cameras, first remove the fixing screws between the card plate 19 and the fixing sleeve 3, pull the card plate 19 out of the card plate slot 20, and then pull down the cover plate 18 to make the positioning rod 23 disengage from the positioning slot 24. At this time, the pushing force of the fixing top rod 21 on the clamping strip 9 disappears.

[0061] After the fixed top rod 21 is removed, the clamping bar 9 moves along the slide groove 11 in a direction away from each other under the elastic force of the spring 16 (the spring 16 pushes the clamping bar 9 through the connecting slide plate 15). The cone clamp 17 disengages from the slot 8, and the C-shaped clamping plate 13 also disengages from the rotation limit plate 7 as the clamping bar 12 resets, and the clamping state is released.

[0062] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
