Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) surveying and mapping, and in particular to an UAV remote sensing surveying and mapping device. Background Art

[0002] Unmanned aircraft, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. They have no cockpit but are equipped with autopilots, program control devices and other equipment. Personnel on the ground, on ships or at the mother aircraft remote control station use radar and other equipment to track, locate, remotely control, telemeter and transmit digital data to them. Equipping the drone with a telemetry plotter allows it to better complete the task of mapping the terrain or other graphics on the ground. Currently, the drones commonly used for joystick mapping are mostly rotary-wing drones.

[0003] Currently, drones equipped with these mapping devices are mostly used for bird's-eye-view aerial mapping. This method is universal and requires only the device to be fixed underneath the drone. However, these drones cannot accurately map some areas. For example, when mapping areas inside jungles, the dense trees prevent drones from flying through them. Deep pits, abysses, and open caves are also difficult for drones to access.

[0004] To this end, the present invention proposes an unmanned aerial vehicle remote sensing mapping device. Summary of the Invention

One side of the push plate is fixedly connected to a transverse limiting waist-shaped frame through a support rod. The longitudinal limiting waist-shaped hole and the transverse limiting waist-shaped frame are both mounted on the outside of adjacent suspension ropes. The frequency conversion drive is used to control the reverse rotation of the rotating shafts on the two longitudinal and transverse vibration transmission mechanisms.

[0014] As a further description of the above technical solution:

[0015] The variable frequency drive comprises a variable frequency motor and a driving gear fixedly sleeved on the output shaft of the variable frequency motor; a passive gear meshing with the driving gear is fixedly sleeved on the rotating shaft.

[0018] As a further description of the above technical solution:

[0019] The winch group includes a winding drum, a driving motor and a bevel gear transmission group. There are two winding drums, each of which is wound with a suspension rope.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-5The invention discloses an unmanned aerial vehicle (UAV) remote sensing mapping device, comprising an unmanned aerial vehicle (UAV) body 1 and a mapping instrument 2. The bottom of the UAV body 1 is connected to the mapping instrument 2 via a suspension portion 3. The suspension portion 3 has the function of releasing and recovering the mapping instrument 2.

[0038] Specifically, the suspension unit 3 comprises a suspension frame 31, a clamping mechanism 32 at the bottom of the suspension frame 31, and a hoist assembly 33 above the clamping mechanism 32. The suspension frame 31 comprises a rectangular frame 311 at the bottom, a ladder frame 312 fixedly connected to the top of the rectangular frame 311, and a hanging plate 313 fixedly connected to the top of the rectangular frame 311 at a corner. A connecting lug 3131 is welded to the top of the hanging plate 313, which is bolted to the bottom of the drone fuselage. The hoist assembly 33 is equipped with two soft steel wire ropes 335. The bottoms of the two suspension ropes 335 are connected to a connecting cage 334. The surveying instrument 2 is fixed to the bottom of the connecting cage 334. The cage-like structure of the connecting cage 334 reduces wind resistance and protects the surveying instrument 2 from impact. When the suspension ropes 335 are raised or lowered, they can drive the surveying instrument up and down through the connecting cage 334. The function of the clamping mechanism 32 is to clamp the connecting cage 334. That is to say, after the suspension rope 335 is wound, the connecting cage 334 will enter the area covered by the clamping mechanism 32. In this area, the clamping mechanism 32 can be controlled to stably clamp the connecting cage 334 after the action is controlled, so as to facilitate the high-speed flight of the UAV in the non-surveying and mapping state.

[0039] The suspension part 3 also includes a variable frequency vibration suppression group 34 located above the clamping mechanism 32 and used to provide high-frequency vibration action to the suspension rope 335. The function of the variable frequency vibration suppression group 34 is to apply a large frequency and small amplitude vibration to the suspension rope 335. This vibration will accelerate the destruction of the frequency and amplitude of the rope swing of the suspension rope 335, so that the rope swing amplitude of the suspension rope 335 will be rapidly reduced, so that the surveying instrument 2 can quickly stay in place stably, ensuring stable surveying and stable stay of the drone.

[0040] Specifically, the variable frequency vibration suppression group 34 includes a variable frequency driver 341 and a longitudinal and transverse vibration transmission mechanism 342. The variable frequency driver 341 is fixedly arranged below the crossbeam 3121 on the ladder frame 312 and is located between the two suspension ropes 335. There are two longitudinal and transverse vibration transmission mechanisms 342, which are respectively located on both sides of the variable frequency driver 341. The variable frequency driver 341 provides vibration driving force to the two suspension ropes 335 through the two longitudinal and transverse vibration transmission mechanisms 342. That is to say, both suspension ropes 335 will be subjected to high-frequency vibration impact force. The variable frequency driver 341 is located in the middle so that when it applies driving force, it can ensure that the entire suspension part 3 is approximately in a state of force balance, thereby avoiding the generation of harmful forces that affect the stable stay of the drone in place.

[0041] The cam 3422 is fixed on the upper side of the cam 3423 and is fixed on the upper side of the cam 3423. The cam 3422 is fixed on the upper side of the cam 3423 and is fixed on the upper side of the cam 3423. The top of the push plate 3422 is rotatably connected to the eccentric shaft 34232 via a connecting rod 3421. The connecting rod 3421 is provided with a longitudinal limiting waist-shaped hole 34211. Both the longitudinal limiting waist-shaped hole 34211 and the transverse limiting waist-shaped frame 342211 are sleeved over the exterior of the adjacent suspension rope 335. Therefore, when the rotating shaft 3423 rotates, it drives the connecting rod 3421 to swing back and forth via the eccentric shaft 34232. As the connecting rod 3421 swings, the longitudinal limiting waist-shaped hole 34211 pushes the suspension rope 335 to swing longitudinally at a high frequency. Simultaneously, the push plate 3422 is driven by the connecting rod 3421 to slide back and forth laterally. A transverse limiting waist-shaped frame 342211 is fixedly connected to one side of the push plate 3422 via a support rod 34221. The transverse limiting waist-shaped frame 342211 drives the suspension rope 335 to swing laterally at a high frequency, thereby causing the entire suspension rope 335 to produce a horizontal universal high-frequency vibration effect. The variable frequency drive 341 is used to control the counter-rotation of the shafts 3423 on the two longitudinal and transverse vibration transmission mechanisms 342. Because the two shafts 3423 rotate in different directions, when the connecting rods 3421 on the two longitudinal and transverse vibration transmission mechanisms 342 are controlled to swing in opposite directions, the inertial resistance generated by the entire variable frequency vibration suppression system 34 after activation will not affect the stability of the drone 1 in staying in place. The variable frequency drive 341 also has the function of adjusting the vibration frequency.

[0042] Specifically, the frequency conversion drive 341 includes a frequency conversion motor 3411 and a driving gear 3412 fixedly mounted on the output shaft of the frequency conversion motor 3411. A driven gear 34231 engaged with the driving gear 3412 is fixedly mounted on the rotating shaft 3423. The frequency conversion motor 3411 drives the driving gear 3412 to rotate, and the driving gear 3412 drives the two driven gears 34231 to rotate, thereby controlling the swing of the two connecting rods 3421.

[0043] In this embodiment, the winch group 33 includes a winding drum 331, a drive motor 332 and a bevel gear transmission group 333. There are two winding drums 331, each of which is wound with a suspension rope 335. The two winding drums 331 are both mounted on the crossbeam 3121 and are rotatable. The drive motor 332 is fixedly arranged in the positioning seat 31211 and is located between the two winding drums 331. The positioning seat 31211 is a casing structure. The output shaft of the drive motor 332 is connected to the two winding drums 331 through the bevel gear transmission group 333. The bevel gear transmission group 333 includes a driving bevel gear and two passive bevel gears, wherein one end of the winding drum 331 is welded with a short sleeve fixedly connected to the passive bevel gear. The driving bevel gear is fixedly connected to the output shaft of the drive motor 332, and the driving bevel gear and the two passive bevel gears are engaged at the same time.

[0044] Furthermore, the clamping mechanism 32 includes a portal frame 321, a traction rod 322 and a connecting shaft 323. There are two portal frames 321, which are rotatably connected to the bottom of the rectangular frame 311 and close to the side. The open ends of the two portal frames 321 are fixedly connected with a clamping rod 3211, and the top of the rectangular frame 311 is fixedly connected with a longitudinal beam 3112 located below the frequency conversion motor 3411. The longitudinal beam 3112 and the connecting shaft 323 are connected for sliding up and down. In specific implementation, a limiting guide sleeve arranged on the outside of the connecting shaft 323 can be welded on the longitudinal beam 3112, and the two sides of the connecting shaft 323 are hingedly connected to the two sides of the two portal frames 321 through the traction rod 322. When the control coupling shaft 323 is moved up and down, the traction rod 322 drives the portal frame 321 to swing. The coupling cage 334 is a cylindrical structure with a spherical top, which is a hollow sphere. When the portal frame 321 swings inward until the clamping rod 3211 and the outer spherical wall of the coupling cage 334 abut against each other, the coupling cage 334 is clamped by the clamping rod 3211. The clamping rod 3211 is a curved rod structure. In specific implementation, an electric push rod (not shown) can be installed on the longitudinal beam 3112 to control the up and down movement of the coupling shaft 323.

[0045] A grooved rod 3341 is fixedly connected to the top of the connection cage 334 , and the two free ends of the grooved rod 3341 are fixedly connected to the two suspension ropes 335 . The arrangement of the grooved rod 3341 causes the center of gravity of the connection cage 334 to move downward.

[0046] Example 2

[0047] See also Figure 3 and Figure 4The difference from Example 1 is that a threaded sleeve 3231 coaxial with the output shaft of the variable frequency motor 3411 is welded to the top of the connecting shaft 323, and the output shaft end of the variable frequency motor 3411 is fixedly connected to a screw 34111 screwed together with the threaded sleeve 3231. The connecting shaft 323 is set to pass through the longitudinal beam 3112, and the top of the grooved rod 3341 is fixedly connected to the top of the connecting shaft 323. The top rod 33411 is located below the connecting shaft 323. When the connecting cage 334 is lifted, the top rod 33411 on it will press the connecting shaft. 323, at this time the connecting shaft 323 will be pushed up, thereby triggering the clamping mechanism 32, this setting does not require any electric push rod assembly, reduces the cost investment and the overall weight of the device, and improves the flight flexibility, when the threaded sleeve 3231 and the screw 34111 are against each other, at this time the frequency conversion motor 3411 is controlled to flip, and the screw 34111 will be screwed into the threaded sleeve 3231, this setting greatly improves the reliability of the fastening of the connecting cage 334 of the suspension part 3, and facilitates the stable and high-speed flight of the UAV.

[0048] The driving gear 3412 is a ratchet gear structure, that is, when the variable frequency motor 3411 rotates forward, it drives the driving gear 3412 to rotate, and when it rotates reversely, the driving gear 3412 does not rotate.

[0049] Working principle: When it is necessary to survey and map the jungle, the drone 1 is controlled to fly above the jungle and hover, and then the drive motor 332 is started. Under the transmission of the bevel gear transmission group 333, the winding drum 331 releases two suspension ropes 335, and the connecting cage 334 drives the surveyor 2 to descend and penetrate into the jungle. Due to external factors (such as airflow), when the taut suspension rope 335 swings greatly, the frequency conversion motor 3411 is started at this time. Under the transmission of the driving gear 3412 and the driven gear 34231, the rotating shaft 3423 will rotate at a high speed, and the eccentric shaft 3423 will rotate at a high speed. 2 drives the connecting rod 3421 to swing back and forth, and the push plate 3422 is driven by the connecting rod 3421 to slide back and forth horizontally. At this time, the longitudinal limit waist-shaped hole 34211 pushes the suspension rope 335 to swing longitudinally at a high frequency, and the transverse limit waist-shaped frame 342211 drives the suspension rope 335 to swing transversely at a high frequency, thereby causing the entire suspension rope 335 to produce a horizontal universal high-frequency vibration effect. The high-frequency vibration of the taut suspension rope 335 creates a swing damping force on its large swing amplitude. This damping force gradually prolongs the swing duration and gradually reduces the swing amplitude, ultimately making the entire surveying device 2 in a nearly stable state. Once the surveying device 2 is stable, it can carry out jungle surveying operations.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
