[0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. It has no cockpit but is equipped with autopilot, program control device 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 digitally transmit the aircraft. Equipping the UAV with a remote sensing mapping instrument enables it to better complete the task of mapping the terrain or other graphics on the ground. Currently, the most common UAVs used for joystick mapping are mostly rotor UAVs.

[0003] At present, the drones carrying surveying instruments are mostly used for aerial bird's-eye surveying. This surveying method is universal and only requires the surveying instrument to be fixed under the drone. However, for some areas, such drones cannot accurately survey, for example, for surveying the inner areas of some jungles, the drones cannot fly in due to the dense trees, and for some deep pits, abysses, open caves, etc., it is not conducive for drones to fly into the areas.

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 driver comprises a variable frequency motor and a driving gear fixedly sleeved on the output shaft of the variable frequency motor, and a passive gear meshing with the driving gear is fixedly sleeved on the rotating shaft.

[0016] As a further description of the above technical solution:

[0017] A suspension shaft is fixedly connected to the inner side of the side beam, and two limiting groove wheels located between adjacent suspension ropes are arranged at the free end of the suspension shaft. A guide sleeve sleeved on the outside of the suspension shaft is welded to the top of the push plate.

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

[0019] The winch unit 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.

In the present invention, a vertical and horizontal vibration transmission mechanism is arranged on the variable frequency vibration suppression group, and the vertical and horizontal vibration transmission mechanism includes a connecting rod and a push rod. The connecting rod is set to swing, and the push rod is set to slide laterally. The high-frequency reciprocating action of the connecting rod and the push rod will exert horizontal and vertical vibration impact forces on the suspension rope, so that the suspension rope is in a high-frequency universal vibration state. This setting has the function of accelerating and reducing the swing amplitude of the surveying and mapping instrument swinging in any direction, so that the stability of the suspended surveying and mapping instrument staying in place is more reliable.

[0027] 3.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1-5, an unmanned aerial vehicle remote sensing mapping device comprises an unmanned aerial vehicle body 1 and a mapping instrument 2, wherein the bottom of the unmanned aerial vehicle body 1 is connected to the mapping instrument 2 via a suspension part 3. The suspension part 3 has the function of releasing and recovering the mapping instrument 2.

[0038] Specifically, the suspension part 3 includes a suspension frame 31, a clamping mechanism 32 located at the bottom of the suspension frame 31, and a winch unit 33 located above the clamping mechanism 32, wherein the suspension frame 31 includes a rectangular frame 311 located at the bottom, a ladder frame 312 is fixedly connected to the top of the rectangular frame 311, a hanging plate 313 located at the corner is fixedly connected to the top of the rectangular frame 311, a connecting ear plate 3131 is welded to the top of the hanging plate 313, and the connecting ear plate 3131 is installed at the bottom of the drone body by bolts. Two suspension ropes 335 are arranged on the winch unit 33, and the suspension ropes 335 are soft steel wire ropes. A connecting cage 334 is connected to the bottom of the two suspension ropes 335, and the surveying instrument 2 is fixedly arranged at the bottom of the connecting cage 334. The cage-shaped structure of the connecting cage 334 can reduce wind resistance and provide impact protection for the surveying instrument 2. When the suspension ropes 335 are raised or lowered, they can drive the surveying instrument to rise or fall 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, after controlling the clamping mechanism 32 to move, it can stably clamp the connecting cage 334, which is convenient for the UAV to fly at high speed in a 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 is rapidly reduced, so that the surveying instrument 2 can quickly stay in place stably, ensuring stable surveying and stable staying 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 upper crossbeam 3121 of the ladder frame 312 and 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, high-frequency vibration impact force will be applied to the two suspension ropes 335. The variable frequency driver 341 is arranged in the middle so that when it applies the 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] Furthermore, the longitudinal and transverse vibration transmission mechanism 342 includes a connecting rod 3421, a push plate 3422 and a rotating shaft 3423. The middle part of the bottom of the cross beam 3121 is fixedly connected to a positioning seat 31211. The rotating shaft 3423 is arranged at the bottom of the positioning seat 31211 and its bottom is fixedly connected to an eccentric shaft 34232 through a connecting arm. The push plate 3422 and the inner side of a side beam 3122 on the ladder frame 312 are laterally slidably connected. In the specific implementation, it is preferred that the inner side of the side beam 3122 is fixedly connected to a suspension shaft 31221, and a guide sleeve 34222 is welded to the top of the push plate 3422 and is sleeved on the outside of the suspension shaft 31221. The free end of the suspension shaft 31221 is provided with two limiting groove wheels 312211 located between adjacent suspension ropes 335. The setting of the limiting groove wheels 312211 makes the lifting and vibration of the suspension rope 335 more stable, and can also reduce the wear rate of the suspension rope 335. The top of the push plate 3422 is rotatably connected by the connecting rod 3421 and the eccentric shaft 34232. The connecting rod 3421 is provided with a longitudinal limit waist-shaped hole 34211. The longitudinal limit waist-shaped hole 34211 and the transverse limit waist-shaped frame 342211 are both sleeved on the outside of the adjacent suspension rope 335. Therefore, when the rotating shaft 3423 rotates, the connecting rod 3421 is driven to swing back and forth through the eccentric shaft 34232. When the connecting rod 3421 swings, the longitudinal limit waist-shaped hole 34211 will push the suspension rope 335 to swing longitudinally at a high frequency. At the same time, the push plate 3422 will be driven by the connecting rod 3421 to slide back and forth laterally. One side of the push plate 3422 is fixedly connected with a transverse limit waist-shaped frame 342211 through a support rod 34221. The transverse limit waist-shaped frame 342211 will drive the suspension rope 335 to swing transversely at a high frequency, thereby making the entire suspension rope 335 produce a horizontal universal high-frequency vibration effect. The variable frequency driver 341 is used to control the reverse rotation of the shafts 3423 on the two longitudinal and transverse vibration transmission mechanisms 342. Since the two shafts 3423 rotate in different directions, when the swing directions of the connecting rods 3421 on the two longitudinal and transverse vibration transmission mechanisms 342 are controlled to be opposite, the inertial resistance generated after the entire variable frequency vibration suppression group 34 is started will not affect the stability of the drone body 1 staying in place. The variable frequency driver 341 has the function of adjusting the vibration frequency.

[0042] Specifically, the frequency conversion driver 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 passive gear 34231 meshing 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 passive gears 34231 to rotate, thereby realizing the control of the swing of the two connecting rods 3421.

[0043] In this embodiment, the winch unit 33 includes a winding drum 331, a driving 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 rotatably arranged. The driving motor 332 is fixedly arranged in a 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 driving motor 332 is connected to the two winding drums 331 through a bevel gear transmission group 333. The bevel gear transmission group 333 includes an active bevel gear and two passive bevel gears, wherein a short-circuit sleeve fixedly connected to the passive bevel gear is welded at one end of the winding drum 331. The active bevel gear and the output shaft of the driving motor 332 are fixedly connected, and the active bevel gear and the two passive bevel gears are meshed 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 clamping rods 3211. 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 slidably connected up and down. In specific implementation, a limiting guide sleeve mounted 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 through the traction rod 322 and the two sides of the two portal frames 321. When the connecting shaft 323 is controlled to move up and down, the traction rod 322 will drive the door frame 321 to swing. The connecting cage 334 is a cylindrical structure with a spherical top. The spherical shape here is a hollow spherical shape. When the door frame 321 swings inward until the clamping rod 3211 and the outer spherical wall of the connecting cage 334 are against each other, the connecting cage 334 is clamped by the clamping rod 3211. The clamping rod 3211 is an arc rod structure. In specific implementation, an electric push rod (not shown in the figure) for controlling the up and down movement of the connecting shaft 323 can be installed on the longitudinal beam 3112.

[0045] A grooved rod 3341 is fixedly connected to the top of the connection cage 334 , and two free ends of the grooved rod 3341 are respectively fixedly connected to 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 4, which is different from Example 1, a threaded sleeve 3231 coaxial with the output shaft of the variable frequency motor 3411 is welded on the top of the connecting shaft 323, and a screw 34111 screwed and connected to the threaded sleeve 3231 is fixedly connected to the output shaft end of the variable frequency motor 3411. The connecting shaft 323 is arranged to penetrate the longitudinal beam 3112, and the top of the grooved rod 3341 is fixedly connected to a push rod 33411 located below the connecting shaft 323. When the connecting cage 334 is lifted, the push rod 33411 on it will press the connecting shaft 323, at this time, the connecting shaft 323 will be pushed up, and then the clamping mechanism 32 can be triggered. This setting does not require any electric push rod components, 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, 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, which is convenient for 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 will not rotate.

[0049] Working principle: When it is necessary to survey 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 bobbin 331 releases two suspension ropes 335, and the connecting cage 334 drives the surveying instrument 2 to descend and penetrate into the jungle. Due to external factors (such as airflow), the taut suspension rope 335 swings greatly. At this time, the frequency conversion motor 3411 is started, and under the transmission of the active gear 3412 and the passive gear 34231, the shaft 3423 rotates at a high speed, and the eccentric shaft 3423 2 drives the connecting rod 3421 to swing back and forth, and the push plate 3422 will be driven by the connecting rod 3421 to slide back and forth horizontally. At this time, the longitudinal limit waist-shaped hole 34211 will push the suspension rope 335 to swing longitudinally at high frequency, and the horizontal limit waist-shaped frame 342211 will drive the suspension rope 335 to swing horizontally at high frequency, thereby making the entire suspension rope 335 produce a horizontal universal high-frequency vibration effect. The high-frequency vibration of the taut suspension rope 335 will produce a swing damping force for its large-amplitude rope swing, and the damping force will gradually prolong the swing time and gradually reduce the swing amplitude, and finally make the entire surveying instrument 2 in a nearly stable state. When the surveying instrument 2 is stable, it can be used for surveying and mapping in the jungle.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
