Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a remote sensing surveying UAV. Background Technology

[0002] Remote sensing drones refer to unmanned aerial vehicles (UAVs) equipped with detection equipment such as optical cameras and multispectral sensors. They acquire and process surface information from the air through non-contact remote sensing methods. Their core function is to efficiently and flexibly acquire high-resolution geospatial data, and they are widely used in many fields such as urban planning, disaster assessment, and precision agriculture.

[0003] Existing drones mostly use cameras fixed to the bottom of the fuselage or mounted on gimbals with limited angles. The adjustment range of this structure is usually limited to the pitch angle. This means that when facing vertical cliffs, the bottom of bridges, or special targets requiring upward-looking shots, the drone cannot directly adjust the lens angle for effective surveying. Instead, it must perform complex and time-consuming adjustments to its flight attitude, severely impacting the comprehensiveness of data acquisition and operational efficiency. Therefore, we propose a remote sensing survey drone. Summary of the Invention

[0004] The purpose of this invention is to provide a remote sensing survey drone to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a remote sensing surveying drone, comprising a drone body, two annular support frames fixedly connected to the middle of the outside of the drone body, annular rotating frames rotatably connected to the outside of the two annular support frames, an mounting plate fixedly connected to the outer wall of the annular rotating frame, a camera fixedly mounted on the side of the mounting plate away from the drone body, an adjustment component for adjusting the position of the camera mounted on the drone body, and a protective component for protecting the camera jointly mounted on the annular rotating frame and one of the annular support frames.

[0006] Preferably, the adjustment assembly includes a motor and two internal gear rings. The motor is fixedly connected to one side of the upper end of the UAV body, and the two internal gear rings are fixedly connected to the inner wall of the annular rotating frame. The output end of the motor is fixedly connected to a connecting shaft, and two spur gears are fixedly sleeved on the outside of the connecting shaft. The two spur gears mesh with the two internal gear rings respectively.

[0007] Preferably, the protective assembly includes a fixing rod, a rack one, and a rack two. The fixing rod is fixedly connected to the side wall of the annular rotating frame, and the rack one and rack two are both fixedly connected to the side wall of one of the annular support frames.

[0008] Preferably, the fixed rod has a lifting groove, a lifting plate is slidably connected to the inner wall of the lifting groove, an installation sleeve is fixedly connected to one end of the lifting plate, a shield is slidably connected inside the installation sleeve, and a cleaning component for cleaning the camera by shaking the shield is installed inside the installation sleeve, with the shield mounted on the cleaning component.

[0009] Preferably, a one-way screw is rotatably connected to the inner wall of the lifting groove, the lifting plate is threaded onto the outside of the one-way screw, and a working groove is provided on the lower side of the fixed rod away from the mounting plate. A first bevel gear and a second bevel gear are rotatably connected to the inner wall of the working groove. The first bevel gear and the second bevel gear mesh with each other. The output end of the first bevel gear penetrates the inner wall of the working groove and is fixedly connected to one end of the one-way screw.

[0010] Preferably, one end of the second bevel gear is fixedly connected to a drive shaft, and a second spur gear is fixedly sleeved on the outside of the drive shaft. The second spur gear meshes with the first rack and the second rack respectively.

[0011] Preferably, the cleaning assembly includes a pole and multiple springs. The pole is fixedly connected to the upper end of the mounting plate, and the multiple springs are all fixedly connected to one side of the inner wall of the mounting sleeve. The baffle is fixedly connected to one end of the multiple springs, and the pole has multiple arc-shaped grooves arranged in an up-down array on the side near the baffle.

[0012] Preferably, a top block is fixedly connected to the side of the shield near the upright, and the end of the top block away from the spring is arc-shaped. The arc-shaped end of the top block matches the arc-shaped groove, and a cleaning sponge is fixedly connected to the side of the shield near the camera.

[0013] Preferably, the lower end of the UAV body is fixedly connected to two symmetrically arranged fixing plates, and each of the two fixing plates is fixedly connected to two legs.

[0014] Preferably, a support plate is fixedly connected to the upper end of the mounting plate, and the support plate is located directly below the shielding plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By driving a spur gear driven by a motor to mesh with the internal gear ring on the inner wall of the ring rotating frame, the camera can rotate continuously along the ring guide rail. This allows the camera to be flexibly adjusted over a wide range of pitch angles on the drone body, from shooting vertically downwards to shooting horizontally or upwards. This significantly improves the drone's adaptability to complex terrain and diverse tasks, thereby greatly enhancing the comprehensiveness of survey data, collection efficiency, and user operating experience.

[0016] 2. As the camera rotates from the bottom to the top of the drone, the shield automatically rises first to block the lens, effectively preventing damage to the precision optical lens from dust, rain, collisions, etc. during flight, take-off, landing, and transportation. When the camera is about to rotate to the top of the drone, the shield automatically lowers in advance, so as not to affect normal shooting, significantly improving the reliability and service life of the equipment.

[0017] 3. During the lifting and lowering of the cover, the intermittent contact between the top block and the arc groove, along with the spring's reset action, causes the cover containing the cleaning sponge to vibrate frequently from side to side. This enables the camera lens to self-clean automatically. In each necessary step of the camera retracting and unfolding, the lens surface is automatically wiped, which can promptly remove attached water stains, dust, and light dirt, ensuring the stability and clarity of image quality, reducing the frequency of manual maintenance, and significantly improving the user's operating experience.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 The present invention provides a technical solution: a remote sensing survey drone, including a drone body 1, two annular support frames 2 fixedly connected to the middle of the outside of the drone body 1, annular rotating frame 3 rotatably connected to the outside of the two annular support frames 2, a mounting plate 4 fixedly connected to the outer wall of the annular rotating frame 3, a camera 5 fixedly mounted on the side of the mounting plate 4 away from the drone body 1, an adjustment component 6 for adjusting the position of the camera 5 mounted on the drone body 1, and a protective component 7 for protecting the camera 5 jointly mounted on the annular rotating frame 3 and one of the annular support frames 2.

[0022] Furthermore, the UAV body 1 serves as the main carrier, with two externally fixed ring support frames 2 forming a stable ring guide rail base. The ring rotating frame 3 is rotatably connected to the outside of the two ring support frames 2, allowing it to rotate along the ring track. The mounting plate 4 fixedly connected to the outer wall of the ring rotating frame 3 is used to mount the camera 5, enabling the camera 5 to rotate together with the ring rotating frame 3, achieving adjustment of the shooting angle from vertically downward to vertically upward. This significantly enhances the UAV body 1's ability to cope with complex terrain and diverse survey tasks. The adjustment component 6 installed on the UAV body 1 is used to drive the position adjustment of the camera 5, achieving adjustment of the camera 5's position around the UAV body 1 by 180 degrees, improving the convenience of operation and the accuracy of angle adjustment. The protective component 7, jointly installed on the ring rotating frame 3 and one of the ring support frames 2, provides automatic protection during the rotation of the camera 5, effectively preventing dust, rain, or collision damage during flight, ensuring the long-term stable operation and service life of the camera 5, realizing angle adjustment and integrated protection of the camera 5, and improving the comprehensiveness of survey data acquisition and equipment reliability.

[0023] It is worth noting that both the UAV body 1 and the camera 5 are existing technologies. The UAV body 1, as a flight platform, mainly includes a rotor power system that provides lift and attitude control, a flight control system that enables autonomous and stable flight, a communication module responsible for data transmission and command reception, and an energy system that supplies power to all components. The camera 5, as the core component for surveying, images the scene onto an image sensor through an optical lens and converts it into digital signals. At the same time, the camera 5 usually integrates or is connected to its own gimbal or servo drive mechanism, which allows the camera 5 to independently swing and adjust its pitch, yaw, and other angles within a certain range on its own mounting base to achieve preliminary image stabilization and target tracking. When adjusting the position of the mounting plate 4, the camera 5 will automatically straighten, so that the lens automatically faces forward. This will not be elaborated further here.

[0024] In the preferred embodiment of this technical solution, please refer to Figures 1-5 As shown, the adjustment component 6 includes a motor 601 and two internal gear rings 602. The motor 601 is fixedly connected to one side of the upper end of the UAV body 1. The two internal gear rings 602 are fixedly connected to the inner wall of the annular rotating frame 3. The output end of the motor 601 is fixedly connected to a connecting shaft 603. Two spur gears 604 are fixedly sleeved on the outside of the connecting shaft 603. The two spur gears 604 mesh with the two internal gear rings 602 respectively.

[0025] Furthermore, after the motor 601 fixed on the drone body 1 is started, it drives the connecting shaft 603 at its output end to rotate. The two spur gears 604 fixedly sleeved on the connecting shaft 603 rotate synchronously. The two spur gears 604 mesh with the two internal gear rings 602 fixedly connected to the inner wall of the annular rotating frame 3, thereby converting the rotational power of the motor 601 into the driving torque of the annular rotating frame 3, causing the annular rotating frame 3 to rotate as a whole. This enables reliable and precise angle adjustment of the camera 5. The position of the camera 5 can be adjusted from directly below the drone body 1 to directly above the drone body 1 and then automatically stops. When it is necessary to reset, the motor 601 reverses, so that the mounting plate 4 can rotate from directly above the drone body 1 to directly below the drone body 1.

[0026] In the preferred embodiment of this technical solution, please refer to Figure 6 and Figure 7 As shown, the protective component 7 includes a fixing rod 701, a rack 1 702 and a rack 2 703. The fixing rod 701 is fixedly connected to the side wall of the annular rotating frame 3, and the rack 1 702 and the rack 2 703 are both fixedly connected to the side wall of one of the annular support frames 2. A lifting groove 704 is provided on the fixed rod 701. A lifting plate 705 is slidably connected to the inner wall of the lifting groove 704. An installation sleeve 706 is fixedly connected to one end of the lifting plate 705. A cover plate 707 is slidably connected inside the installation sleeve 706. A cleaning component 8 for cleaning the camera 5 is installed inside the installation sleeve 706. The cover plate 707 is installed on the cleaning component 8. A one-way screw 708 is rotatably connected to the inner wall of the lifting groove 704. The lifting plate 705 is threaded onto the outside of the one-way screw 708. A working groove 709 is provided on the lower side of the fixed rod 701 away from the mounting plate 4. A first bevel gear 710 and a second bevel gear 711 are rotatably connected to the inner wall of the working groove 709. The first bevel gear 710 and the second bevel gear 711 mesh with each other. The output end of the first bevel gear 710 passes through the inner wall of the working groove 709 and is fixedly connected to one end of the one-way screw 708. One end of the second bevel gear 711 is fixedly connected to the drive shaft 712, and the drive shaft 712 is fixedly sleeved with a second spur gear 713. The second spur gear 713 meshes with the first rack 702 and the second rack 703 respectively.

[0027] Furthermore, during the process of rotating the camera 5 from directly below the drone body 1 to directly above it, the fixed rod 701, which is fixedly connected to the side wall of the annular rotating frame 3, rotates with the annular rotating frame 3. The second spur gear 713, which is fixedly sleeved on the transmission shaft 712, meshes with the first rack 702, which is fixedly connected to the side wall of the annular support frame 2. The rotation of the second spur gear 713 causes the rotation of the transmission shaft 712 to drive the second bevel gear 711, which is fixedly connected to it, to rotate. The second bevel gear 711 drives the first bevel gear 710, which meshes with it, to rotate, thereby causing the one-way screw 708 to rotate within the lifting groove 704. Since the lifting plate 705 is threaded onto the outside of the one-way screw 708 and slidably connected to the inner wall of the lifting groove 704, the rotation of the one-way screw 708 will drive the lifting plate 705 to rise along the lifting groove 704. 05 The mounting sleeve 706, which is fixedly connected to one end of the camera, drives the shield 707, which is slidably connected inside the mounting sleeve 706, to rise and move to the front of the lens of the camera 5. As the camera 5 continues to move, when the camera 5 is about to move above the drone body 1, the second spur gear 713 will mesh with the second rack 703. Since the meshing position of the second rack 703 and the second spur gear 713 is opposite to that of the first rack 702, the one-way screw 708 will rotate in the opposite direction, thereby causing the lifting plate 705 to descend and the shield 707 to move away from the front of the camera 5, so that the camera 5 can be used normally. This achieves automatic shielding protection for the camera 5 during the process of rotating out of the bottom of the drone body 1, and automatic retraction when it reaches the top of the drone body 1 and needs to shoot, effectively preventing external pollution and bumps.

[0028] In the preferred embodiment of this technical solution, please refer to Figure 8 and Figure 9 As shown, the cleaning component 8 includes a pole 801 and multiple springs 802. The pole 801 is fixedly connected to the upper end of the mounting plate 4, and the multiple springs 802 are all fixedly connected to one side of the inner wall of the mounting sleeve 706. The baffle plate 707 is fixedly connected to one end of the multiple springs 802. The pole 801 has multiple arc-shaped grooves 803 arranged in an up-down array on the side near the baffle plate 707. A top block 804 is fixedly connected to the side of the shield 707 near the upright 801. The end of the top block 804 away from the spring 802 is arc-shaped. The arc-shaped end of the top block 804 matches the arc-shaped groove 803. A cleaning sponge 805 is fixedly connected to the side of the shield 707 near the camera 5.

[0029] Furthermore, during the lifting and lowering of the shield 707 along with the mounting sleeve 706, the top block 804 fixedly connected to one side of the shield 707 will periodically slide over multiple arc-shaped grooves 803 opened on the upright 801. When the top block 804 slides out of the arc-shaped grooves 803, it will generate a lateral thrust on the shield 707, causing the shield 707 to slide within the mounting sleeve 706 and compress multiple springs 802. Subsequently, the compressed springs 802 release their elasticity, causing the shield 707 to bounce back to its original position. This process occurs repeatedly during lifting and lowering, causing the shield 707 to vibrate at a high frequency from side to side. The cleaning sponge 805 fixedly connected to the shield 707 vibrates along with it, realizing automatic wiping and cleaning of the camera lens. This effectively removes attached water stains and dust, ensuring image quality and reducing manual maintenance.

[0030] In the preferred embodiment of this technical solution, please refer to Figures 1-4 As shown, the lower end of the drone body 1 is fixedly connected to two symmetrically arranged fixed plates 9, and each fixed plate 9 is fixedly connected to two legs 10.

[0031] Furthermore, two fixed plates 9 symmetrically fixed to the lower end of the UAV body 1 serve as load-bearing and connecting bases, stably transmitting the support structure to the UAV body 1 fuselage. Two legs 10 fixedly connected to each fixed plate 9 serve as grounding support points, contacting the ground when the UAV takes off, lands, parks, or moves, jointly bearing and dispersing the weight of the UAV body 1 fuselage and landing impact, and raising the distance between the UAV body 1 fuselage and the ground, providing operating space and safety clearance for the bottom equipment, and reducing the direct impact and pollution of ground debris on the UAV body 1 fuselage.

[0032] In the preferred embodiment of this technical solution, please refer to Figure 5 As shown, a support plate 11 is fixedly connected to the upper end of the mounting plate 4, and the support plate 11 is located directly below the shielding plate 707.

[0033] Furthermore, when the baffle 707 descends to its lowest position, the bottom end of the baffle 707 finally rests on the upper surface of the support plate 11, providing a stable and reliable storage position and support reference for the baffle 707. This ensures that the baffle 707 can be accurately and stably parked when not in operation, avoiding the baffle 707 from swaying in the air or exerting continuous pressure on the transmission components.

[0034] In this invention, the drone body 1 performs terrain surveying using the camera 5 at its bottom. When surveying complex terrain such as cliffs, the camera 5's shooting angle needs to be adjusted. The motor 601 in the adjustment assembly 6 is then activated. The motor 601 drives the connecting shaft 603 and its two spur gears 604 to rotate. The spur gears 604 mesh with the internal gear ring 602 fixed to the inner wall of the annular rotating frame 3, thereby driving the entire annular rotating frame 3 to rotate along the annular support frame 2. The annular rotating frame 3 then drives the mounting plate 4 on its outer wall and the camera 5 together. The camera 5 rotates to adjust the survey angle from vertically downward to vertically upward, adapting to different survey needs. When the camera 5 adjusts its angle, the fixed rod 701, fixed to the side wall of the annular rotating frame 3, rotates accordingly. The second spur gear 713 meshes with the rack 702, which is fixed to the side wall of one of the annular support frames 2. The rotation of the second spur gear 713 is transmitted to the second bevel gear 711 through the transmission shaft 712. The second bevel gear 711 drives the first bevel gear 710, which meshes with it, to rotate. The output end of the first bevel gear 710 drives the one-way screw 708 in one direction. Rotation: Because the lifting plate 705 and the one-way screw 708 are threadedly fitted, the rotation of the one-way screw 708 drives the lifting plate 705 to move upward along the lifting groove 704. The lifting plate 705 drives the shielding plate 707 to rise as a whole through the mounting sleeve 706. The shielding plate 707 and the cleaning sponge 805 at the front end of the shielding plate 707 quickly move upward, timely covering the front of the lens before the camera 5 completely rotates out of the bottom area of ​​the fuselage, forming physical protection to prevent the camera 5 from getting contaminated with external impurities during flight. During the lifting and lowering process of the shielding plate 707, it is fixed to the shielding plate. The top block 804 on the side of the baffle 707 periodically contacts and disengages from multiple arc-shaped grooves 803 on the surface of the upright 801 fixed on the upper end of the mounting plate 4. When the arc-shaped end of the top block 804 slides out of the arc-shaped groove 803, it will generate a lateral thrust on the baffle 707, compressing the spring 802. When the top block 804 slides into the arc-shaped groove 803, the compressed spring 802 quickly releases its elasticity, causing the baffle 707 to bounce back to its original position, so that the baffle 707 and the cleaning sponge 805 generate high-frequency left and right vibration, effectively removing the dust attached to the lens. As camera 5 gradually moves from the bottom of the drone body 1 towards the top, spur gear 2 713 engages with rack 2 703. Because rack 2 703 and rack 1 702 are engaged with spur gear 2 713 at different positions, spur gear 2 713 reverses direction, causing the shield 707 to descend. During descent, the shaking cleaning function of cleaning component 8 is activated again to clean the lens. The shield 707 is fully lowered, and its bottom falls back onto the support plate 11. Camera 5's lens is fully exposed, allowing for unobstructed shooting and preparation for executing new survey commands. This enables adjustment of the survey angle, significantly improving the reliability, data quality, and maintenance convenience of the drone body 1 in complex environments.
