Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) remote sensing data acquisition devices, and particularly to a UAV remote sensing data acquisition device. Background Art

[0002] UAV remote sensing data acquisition is an efficient data acquisition method that has emerged in recent years. By carrying a variety of sensors on UAVs, it can flexibly and quickly obtain high-resolution remote sensing data. In terms of equipment, UAVs can carry different sensors such as optical cameras, multispectral cameras, and thermal infrared cameras according to mission requirements. Optical cameras can obtain high-resolution visible light images for ground object recognition; multispectral cameras can detect electromagnetic wave information in different bands to analyze vegetation health, water quality pollution, etc.; thermal infrared cameras can sense the thermal radiation differences of objects and are suitable for power line inspection, forest fire prevention, etc. During the acquisition process, the flight route is planned based on the mission objectives to determine parameters such as flight altitude, speed, and shooting angle. The UAV flies along the predetermined route, and the sensors work synchronously to continuously collect data. Compared with traditional remote sensing means, it has many advantages. It has strong flexibility and can operate in complex terrains and small areas without being restricted by large equipment operations; it can obtain high-resolution data to accurately reflect the details of ground objects; and it has a relatively low cost without the need to use expensive satellite or manned aircraft remote sensing equipment. Nowadays, UAV remote sensing data acquisition has been widely used in many fields such as agricultural monitoring, urban planning, environmental assessment, and disaster emergency response, providing strong data support for decision-making in various industries.

[0003] Most traditional UAV remote sensing data acquisition devices are externally mounted at the bottom of the UAV body. Due to the complex aerial environment, during the flight of the UAV, the remote sensing data acquisition device may be impacted by airborne suspended matter, resulting in device damage. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a UAV remote sensing data acquisition device, which solves the problem that most traditional UAV remote sensing data acquisition devices are externally mounted at the bottom of the UAV body. Due to the complex aerial environment, during the flight of the UAV, the remote sensing data acquisition device may be impacted by airborne suspended matter, resulting in device damage.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A drone remote sensing data acquisition device includes a fuselage. A first mounting plate is provided at the bottom of the fuselage. A connecting rod is provided at the bottom of the first mounting plate. The bottom of the connecting rod is fixedly connected to a remote sensing data collector. The bottom of the first mounting plate is fixedly connected to the top surface of a first protective shell. A second protective shell is provided on the outer side of the first protective shell. Both the first protective shell and the second protective shell are hollow structures. The first protective shell is located inside the second protective shell. The connecting rod is located inside the first protective shell. A driving device is provided between the first protective shell and the second protective shell. The driving device can control the second protective shell to move up and down on the outer wall of the first protective shell.

[0006] Preferably, the driving device includes a motor. One side of the motor away from the output end is fixedly connected to the inner wall of the first protective shell. The output end of the first protective shell is fixedly connected to a worm. A gear is provided on the side of the worm away from the motor. Tooth teeth are provided on the inner wall of the second protective shell. The tooth ends of the tooth teeth are meshed with the tooth ends of the gear.

[0007] Preferably, a sliding groove is provided on the outer wall of the first protective shell. A pulley is provided on the inner wall of the second protective shell. The pulley fits with the inner wall of the sliding groove.

[0008] Preferably, a second limiting plate is provided at the lower section of the sliding groove.

[0009] Preferably, a worm gear is provided on the outer wall of the connecting rod. A rotating plate is fixedly connected to the top of the connecting rod. A rotating hole is provided on the bottom surface of the first mounting plate. The rotating plate is located inside the rotating hole. The tooth ends of the worm gear are meshed with the middle part of the worm.

[0010] Preferably, a rack is provided on the outer wall where the worm intersects with the gear. A tooth groove is provided in the middle of the gear. The rack fits with the tooth groove. A first limiting plate is provided at the end of the worm away from the motor. A rotating groove is provided on the outer wall of the gear close to the motor. A second mounting plate is fixedly connected to the inner wall of the first protective shell. The inner wall of the second mounting plate is fixedly connected to one side of the electric push rod away from the output end. The output end of the electric push rod is fixedly connected to an enlarged head through a connecting rod. The enlarged head is located inside the rotating groove.

[0011] Preferably, a contraction groove is provided on the bottom surface of the first mounting plate. A second magnet is fixedly connected to the top of the contraction groove. A first magnet is fixedly connected to the top of the second protective shell. The first magnet and the second magnet are in corresponding positions. The thickness of the second protective shell fits with the width of the contraction groove.

[0012] Preferably, legs are provided at the bottom of the fuselage. The bottom surface of the legs is lower than the bottom edge when the second protective shell extends out.

[0013] Working principle: The motor outputs rotational force to drive the worm to rotate. The electric push rod outputs thrust to control the gear to move forward, so that the tooth end of the gear meshes with the tooth end of the tooth. Then, it controls the second protective shell to move downward, so that the second protective shell shields the remote sensing data collector. Then, when the aircraft is started and flies to the collection area, the gear is controlled to mesh with the tooth by the electric push rod. Then, the motor outputs rotational force to drive the second protective shell to move upward until the first magnet fits with the second magnet. Then, the gear is controlled to disengage from the tooth by the electric push rod, and the motor controls the worm to rotate, thereby driving the worm gear to rotate, so that the remote sensing data collector rotates, and then the data collection task is completed.

[0014] The present invention provides a drone remote sensing data collection device. It has the following beneficial effects:

[0015] 1. In the present invention, the first protective shell outside the connecting rod can play the role of installing the second protective shell. The second protective shell can move up and down on the outer wall of the first protective shell, so as to shield the remote sensing data collector during flight and expose the remote sensing data collector during collection, thus solving the problem that most traditional drone remote sensing data collection devices are externally hung at the bottom of the drone body. Due to the complex air environment, the remote sensing data collection device may be impacted by airborne suspended matter during the flight of the drone, resulting in device damage.

[0016] 2. In the present invention, the motor can drive the worm to rotate and can also drive the gear to rotate. Then, the rotational force can be transmitted to the worm gear to make the remote sensing data collector rotate horizontally to achieve the purpose of large-range collection. At the same time, the rotational force can also be transmitted to the tooth to drive the second protective shell to move up and down to achieve the purpose of shielding and exposing the remote sensing data collector. Thus, these two operations can be achieved only by one motor, so as to save parts.

[0017] 3. In the present invention, the pulley arranged on the inner wall of the second protective shell can slide on the inner wall of the chute on the outer wall of the first protective shell, so as to limit the shaking when the second protective shell moves up and down, and then achieve the purpose of stabilizing the moving process of the second protective shell, thus avoiding shaking and colliding with the remote sensing data collector.

Specific embodiments

[0029] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to the attached Figure 1 - attached Figure 5, an embodiment of the present invention provides a UAV remote sensing data acquisition device, including a body 1. A first mounting plate 2 is provided at the bottom of the body 1. A connecting rod 14 is provided at the bottom of the first mounting plate 2. A remote sensing data collector 16 is fixedly connected to the bottom of the connecting rod 14. The bottom of the first mounting plate 2 is fixedly connected to the top surface of the first protective shell 3. A second protective shell 5 is provided on the outside of the first protective shell 3. Both the first protective shell 3 and the second protective shell 5 are hollow structures. The first protective shell 3 is located inside the second protective shell 5. The connecting rod 14 is located inside the first protective shell 3. A driving device is provided between the first protective shell 3 and the second protective shell 5. The driving device can control the second protective shell 5 to move up and down on the outer wall of the first protective shell 3.

[0031] Specifically, the body 1 can carry the remote sensing data collector 16; the first mounting plate 2 can mount the connecting rod 14 at the bottom of the body 1; the connecting rod 14 can mount the remote sensing data collector 16 at the bottom of the first mounting plate 2; the remote sensing data collector 16 can collect remote sensing data; the first protective shell 3 and the second protective shell 5 can shield the remote sensing data collector 16, thereby protecting the remote sensing data collector 16, and solving the problem that most traditional UAV remote sensing data acquisition devices are externally mounted at the bottom of the UAV body. Due to the complex aerial environment, the remote sensing data acquisition device may be impacted by airborne suspended matter during the flight of the UAV, resulting in device damage; the driving device provided between the first protective shell 3 and the second protective shell 5 can control the second protective shell 5 to slide up and down outside the first protective shell 3, thereby achieving the purpose of sliding up to expose the remote sensing data collector 16 to start data acquisition, and at the same time achieving the purpose of sliding down to shield the remote sensing data collector 16 to protect the remote sensing data collector 16.

[0032] Please refer to the attached Figure 6 - attached Figure 8 , the driving device includes a motor 22. One side of the motor 22 away from the output end is fixedly connected to the inner wall of the first protective shell 3. The output end of the first protective shell 3 is fixedly connected to a worm 21. A gear 19 is provided on the side of the worm 21 away from the motor 22. Tooth teeth 11 are provided on the inner wall of the second protective shell 5. The tooth ends of the tooth teeth 11 are meshed with the tooth ends of the gear 19.

[0033] Specifically, the motor 22 can output rotational force; the worm 21 can transmit rotational force; the gear 19 can transmit the rotational force transmitted by the worm 21 to the surface of the tooth 11. Thus, the motor 22 can output rotational force to drive the worm 21 to rotate, thereby driving the gear 19 to rotate. Since the tooth 11 is fixedly connected to the inner wall of the second protective case 5, the upper and lower movement of the second protective case 5 is achieved through the meshing of the tooth end of the tooth 11 and the tooth end of the gear 19.

[0034] Please refer to the attached Figure 9 - attached Figure 10 , a chute 17 is provided on the outer wall of the first protective case 3, and a pulley 10 is provided on the inner wall of the second protective case 5. The pulley 10 fits with the inner wall of the chute 17.

[0035] Specifically, the chute 17 can play a role in clamping the pulley 10, so that the pulley 10 can slide up and down on the inner wall of the chute 17. When the second protective case 5 moves up and down, the pulley 10 slides up and down on the inner wall of the chute 17, making the up and down movement of the second protective case 5 smoother and more stable.

[0036] Please refer to the attached Figure 10 , a second limiting plate 20 is provided at the lower section of the chute 17.

[0037] Specifically, the second limiting plate 20 can play a role in restricting the movement of the pulley 10, so that the pulley 10 stops sliding when it slides to the top surface of the second limiting plate 20, thereby controlling the second protective case 5 to stop sliding down and preventing the second protective case 5 from detaching from the first protective case 3.

[0038] Please refer to the attached Figure 3 - attached Figure 5 , a worm gear 15 is provided on the outer wall of the connecting rod 14. A rotating plate 13 is fixedly connected to the top of the connecting rod 14. A rotating hole 9 is provided on the bottom surface of the first mounting plate 2. The rotating plate 13 is located inside the rotating hole 9. The tooth end of the worm gear 15 meshes with the middle part of the worm 21.

[0039] Specifically, the worm gear 15 can play a role in meshing with the worm 21. Thus, when the worm 21 rotates through the motor 22, the rotational force is transmitted to the worm gear 15, driving the connecting rod 14 to rotate, enabling the remote sensing data collector 16 to rotate 360 degrees, thereby obtaining a larger detection range; the rotating hole 9 can play a role in placing the rotating plate 13; the rotating plate 13 can play a role in connecting the connecting rod 14, enabling the connecting rod 14 to drive the remote sensing data collector 16 to freely rotate inside the rotating hole 9 through the rotating plate 13.

[0040] Please refer to the attached Figure 7 - attached Figure 8, a rack 12 is provided on the outer wall where the worm 21 intersects with the gear 19. A tooth groove is formed in the middle of the gear 19, and the rack 12 fits with the tooth groove. A first limit plate 18 is provided at one end of the worm 21 away from the motor 22. A rotation groove 24 is formed on the outer wall of the gear 19 close to the motor 22. A second mounting plate 23 is fixedly connected to the inner wall of the first protective shell 3, and the inner wall of the second mounting plate 23 is fixedly connected to the side of the electric push rod 25 away from the output end. The output end of the electric push rod 25 is fixedly connected with an expansion head through a connecting rod, and the expansion head is located inside the rotation groove 24.

[0041] Specifically, the rack 12 can play a role in fitting with the tooth groove, so that the gear 19 can move back and forth along the rack 12, and at the same time, the rotational force transmitted by the worm 21 can be transmitted to the gear 19; the first limit plate 18 can play a role in restricting the moving range of the gear 19, thus preventing the gear 19 from moving excessively and disengaging from the worm 21; the rotation groove 24 can play a role in placing the expansion head, so that when the gear 19 rotates, the expansion head will not hinder the rotation; the second mounting plate 23 can play a role in mounting the electric push rod 25 on the inner wall of the first protective shell 3; the electric push rod 25 can play a role in outputting a driving force, and the connecting rod at the output end can drive the expansion head to move back and forth, thereby driving the gear 19 to move back and forth, so that the gear 19 reaches a state of meshing or non-meshing with the tooth 11. In the non-meshing state, the motor 22 can control the worm wheel 15 to rotate clockwise and counterclockwise arbitrarily, and thus will not drive the second protective shell 5 to move up and down, avoiding misoperation.

[0042] Please refer to the appendix Figure 3 - appendix Figure 4 , a contraction groove 8 is formed on the bottom surface of the first mounting plate 2. A second magnet 7 is fixedly connected to the top of the contraction groove 8. A first magnet 4 is fixedly connected to the top of the second protective shell 5. The first magnet 4 and the second magnet 7 are in corresponding positions, and the thickness of the second protective shell 5 fits with the width of the contraction groove 8.

[0043] Specifically, the contraction groove 8 can play a role in retracting and releasing the second protective shell 5, so that the remote sensing data collector 16 can be completely released without hindering the collection work; the second magnet 7 can play a role in attracting the first magnet 4, so that the second protective shell 5 can be fixed inside the contraction groove 8. When the second protective shell 5 is moved into the contraction groove 8 by the motor 22, the second protective shell 5 can be fixed inside the contraction groove 8 by the first magnet 4 and the second magnet 7. When the electric push rod 25 controls the gear 19 to form a non-meshing state with the tooth 11, the second protective shell 5 will not fall off. When the motor 22 controls the second protective shell 5 to move down, only the magnetic force needs to be overcome.

[0044] Please refer to the appendix Figure 1 - appendix Figure 2, legs 6 are provided at the bottom of the body 1, and the bottom surface of the legs 6 is lower than the bottom edge when the second protective shell 5 extends out.

[0045] Specifically, the legs 6 can play a role in supporting the body 1; since the bottom surface of the legs 6 is lower than the bottom edge when the second protective shell 5 extends out, it can be avoided that the too-low legs 6 cause the remote sensing data collector 16 to contact the ground during landing, thereby damaging the remote sensing data collector 16.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
