Description

Technical Field

[0001] This utility model belongs to the field of natural resource surveying and mapping technology, specifically relating to a drone device for field natural resource surveying and mapping. Background Technology

[0002] Natural resource surveying is a process that comprehensively utilizes surveying and mapping technologies to acquire, process, analyze, and express the spatial distribution, quantity, quality, and other characteristics of natural resources. Its aim is to provide basic data and technical support for the investigation, monitoring, registration, protection, and development of natural resources. Its core is to accurately grasp the current status and changes of natural resources, providing a basis for scientific management and sustainable utilization. Natural resource surveying often requires the use of unmanned aerial vehicles (UAVs) for terrain exploration. A UAV is an aircraft that can fly autonomously or remotely without direct human control. Equipped with sensors, cameras, communication equipment, and other payloads, it performs various tasks such as reconnaissance, monitoring, transportation, and entertainment. Its core characteristics are unmanned operation, intelligence, and multifunctionality, and it has been widely used in military, civilian, and commercial fields.

[0003] Chinese patent CN217836050U discloses a UAV mapping instrument for natural resource surveying, comprising a UAV body and a mapping instrument. The UAV body has wings at both ends on its sides, and support frames are fixedly connected to both sides of its bottom. The mapping instrument is located at the bottom of the UAV body, and a lens is fixedly connected to its bottom. This UAV mapping instrument for natural resource surveying includes a housing, support arm, reduction motor, helical gear disk, and helical gear. In use, activating the reduction motor drives the helical gear to rotate, which in turn drives the helical gear disk to rotate. The helical gear disk then drives the support arm to rotate, which in turn drives the mapping instrument to rotate and adjust its angle. This allows for automatic and flexible adjustment of the mapping instrument's angle according to usage needs, greatly reducing the limitations of the equipment and solving the problem of limited use due to the inability to automatically and flexibly adjust the angle.

[0004] However, while the above-mentioned technical solution can achieve the purpose of adjusting the angle of the surveying instrument, the surveying instrument is only fixed by tightening the threaded block and threaded groove during installation. However, the high-frequency vibration of the UAV during flight may cause the threaded connection to gradually loosen, resulting in the surveying instrument becoming loose during use. Consequently, when adjusting the angle of the surveying instrument, the loose threaded connection of the surveying instrument itself makes it difficult to adjust the angle, resulting in adjustment deviation and making it difficult to carry out surveying work smoothly. Therefore, it has certain limitations in use. Utility Model Content

[0005] The purpose of this invention is to provide a drone device for surveying natural resources in the field, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A drone device for surveying natural resources in the field includes: a drone body, a surveying instrument disposed below the drone body, support legs fixedly connected to both sides of the bottom of the drone body, an adjustment frame disposed below the drone body, a positioning post fixedly connected to the center of the top of the adjustment frame, a support plate fixedly connected to the top of the positioning post, two inclined plates rotatably disposed on the top of the support plate, a connecting block fixedly connected to the top of the inclined plates, two ball bearings rotatably disposed inside the connecting block, two guide rods sliding and passing through the inside of the support plate, a pressing block fixedly connected to the top of the guide rods, a first return spring fixedly connected to the bottom of the pressing block, and the bottom end of the first return spring fixedly connected to the top of the support plate, a plug-in post fixedly connected to the center of the top of the support plate, two plug-in holes formed inside the plug-in post, a rotating ring fixedly connected to the center of the bottom of the drone body, a through hole formed in the center of the bottom of the rotating ring, and the surface of the plug-in post passing through the interior of the through hole.

[0007] Preferably, a connecting cylinder is fixedly connected to the middle of the inner top wall of the rotating ring, and a fixing tube is fixedly connected to the bottom ends of both sides of the connecting cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The positioning column drives the bearing plate to contact the bottom of the rotating ring, the inclined plate is squeezed and opened, the ball rolls at the bottom of the rotating ring to increase the opening angle of the inclined plate, and at the same time squeezes the guide rod and the lower pressure block. The first return spring is squeezed, the plug-in column rises and inserts into the through hole and the inside of the connecting cylinder. When the plug-in column is inserted into the connecting cylinder, it squeezes the arc of the clamping rod, causing the two clamping rods to move away from each other. The second return spring is squeezed. When the plug-in hole inside the plug-in column corresponds to the position of the clamping rod, the second return spring resets and causes the clamping rod to insert into the plug-in hole, thereby fixing the plug-in column, making the surveying instrument stable, avoiding the problem of loose connection caused by vibration, and improving the reliability of the equipment.

[0013] (2) When the staff controls the first servo motor, the gear will rotate, which in turn will rotate the rotating ring, and then drive the surveying instrument to rotate, so as to achieve the purpose of horizontal angle adjustment. When the second servo motor works, it will drive the worm to rotate, and through the worm to drive the worm wheel, the surveying instrument will rotate clockwise or counterclockwise, and its angle will be adjusted again. This design allows the surveying instrument to make flexible angle adjustments in the horizontal and vertical directions, expands the surveying range, and improves the efficiency and accuracy of surveying work.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please see Figures 1 to 5 As shown, a drone device for surveying natural resources in the field includes a drone body 1, a surveying instrument 2 located below the drone body 1, support legs 3 fixedly connected to both sides of the bottom of the drone body 1, an adjustment frame 4 located below the drone body 1, a positioning post 5 fixedly connected to the middle of the top of the adjustment frame 4, a bearing plate 6 fixedly connected to the top of the positioning post 5, two inclined plates 7 rotatably mounted on the top of the bearing plate 6, a connecting block fixedly connected to the top of the inclined plate 7, two ball bearings 8 rotatably mounted inside the connecting block, two guide rods 9 sliding and passing through the inside of the bearing plate 6, a pressing block fixedly connected to the top of the guide rods 9, a first return spring 10 fixedly connected to the bottom of the pressing block, and the bottom end of the first return spring 10 fixedly connected to the top of the bearing plate 6, a plug-in post 11 fixedly connected to the middle of the top of the bearing plate 6, two plug-in holes 19 opened inside the plug-in post 11, a rotating ring 12 fixedly connected to the middle of the bottom of the drone body 1, a through hole 13 opened in the middle of the bottom of the rotating ring 12, and the surface of the plug-in post 11 passing through the interior of the through hole 13.

[0017] The design of the UAV body 1 facilitates the movement of the surveying instrument 2 in the air, enabling it to easily map the terrain. The surveying instrument 2 is existing technology and will not be described in detail. The support leg 3 provides support when the UAV body 1 is stationary. The positioning post 5 secures the carrier plate 6, which in turn allows the tilting plate 7 to rotate within it. The tilting plate 7 is rotatably connected to the carrier plate 6 via a rotating shaft. The connecting block allows the ball bearing 8 to rotate within it, ensuring smoother rolling of the ball bearing 8 when the tilting plate 7 is compressed. The guide rod 9 and the pressure block cause the tilting plate 7 to compress when its top is pressed, compressing the first return spring 10. As the guide rod 9 continues to move downwards and the carrier plate 6 moves upwards, the insertion post 11 inserts into the through hole 13.

[0018] A connecting cylinder 14 is fixedly connected to the middle of the inner top wall of the rotating ring 12. A fixing tube 15 is fixedly connected to the bottom ends of both sides of the connecting cylinder 14. A second return spring 16 is fixedly connected to one side of the inner wall of the fixing tube 15.

[0019] The connecting tube 14 allows the fixing tube 15 to be installed and fixed at its bottom ends on both sides, and the fixing tube 15 facilitates the fixing of the second return spring 16 to its inner side wall.

[0020] The second return spring 16 is fixedly connected to a snap-fit ​​rod 17 at one end away from the inner wall of the fixed tube 15. A pull rod 18 is fixedly connected to one end of the snap-fit ​​rod 17, and the surface of the pull rod 18 slides through the interior of the fixed tube 15.

[0021] The locking rod 17 is designed so that when the plug post 11 is inserted into it and moves upward, the end of the locking rod 17 with the arc will be squeezed. At this time, the two locking rods 17 will move in a direction away from each other. At this time, the second return spring 16 will be squeezed and compressed, and at the same time, it will pull the rod 18 to move in a direction away from each other. When the plug hole 19 inside the plug post 11 moves upward and corresponds to the position of the locking rod 17, the second return spring 16 will reset and insert into the inside of the plug hole 19, thereby keeping the plug post 11 fixed inside the connecting cylinder 14. At this time, the surveying instrument 2 and its surrounding structure will be fixed.

[0022] A first protective shell is fixedly connected to one side of the bottom center of the UAV body 1. A first servo motor 20 is fixedly connected inside the first protective shell, and a gear 21 is fixedly connected to the output end of the first servo motor 20. The first servo motor 20 provides a certain driving force for the rotation of the gear 21.

[0023] A toothed ring 22 is fixedly connected to the bottom end of the surface of the rotating ring 12, and the surface of the toothed ring 22 meshes with the surface of the gear 21. The rotation of the gear 21 drives the toothed ring 22 to rotate, thereby causing the rotating ring 12 to rotate. A rotating shaft is fixedly connected to the middle of the top of the rotating ring 12, and the top end of the rotating shaft is rotatably connected to the bottom of the UAV body 1.

[0024] A second protective shell is fixedly connected to the middle of one side of the adjustment frame 4. A second servo motor 23 is fixedly connected inside the second protective shell. A worm gear 24 is fixedly connected to the output end of the second servo motor 23. A worm wheel 25 meshes with the surface of the worm gear 24.

[0025] The second servo motor 23 provides a certain driving force for the rotation of the worm gear 24, so that when the worm gear 24 rotates, it drives the worm wheel 25 meshing with it to rotate. It should be noted that a connecting rod is fixedly connected inside the worm wheel 25. The end of the connecting rod away from the worm wheel 25 is fixedly connected to the back of the surveying instrument 2, and the other end of the connecting rod is fixed and passes through the inside of the worm wheel 25 and is rotatably connected to the inner wall of the adjusting frame 4 to ensure the stability of the worm wheel 25 when it rotates.

[0026] The working principle of this utility model is as follows: The operator moves the positioning post 5 upward in advance, and then the moving bearing plate 6 of the positioning post 5 contacts the bottom of the rotating ring 12. At this time, the inclined plate 7 is squeezed, and the ball bearing 8 rolls at the bottom of the rotating ring 12, so that the two inclined plates 7 are continuously squeezed, making their opening angle larger. At the same time, the inclined plates 7 squeeze the guide rod 9 and the lower pressure block downward. At this time, the first return spring 10 is squeezed. During this process, the insertion post 11 will also rise, so that it is inserted into the interior of the through hole 13, and finally inserted into the interior of the connecting cylinder 14. When it is inserted into the interior of the connecting cylinder 14, the arc of the locking rod 17 is squeezed in advance, so that the two locking rods 17 move away from each other. At this time, the second return spring 16 is squeezed, so that it is compressed until the position of the insertion hole 19 inside the insertion post 11 is aligned with the locking rod. After the position of 17 is aligned, the second reset spring 16 resets, allowing the locking rod 17 to be inserted into the insertion hole 19, thus fixing the insertion post 11. At this point, the surveying instrument 2 is stably installed. Subsequently, the staff controls the first servo motor 20 to work. The output end of the first servo motor 20 drives the gear 21 to rotate, which in turn drives the gear ring 22 to rotate, thereby causing the rotating ring 12 to rotate, thus causing the surveying instrument 2 to rotate horizontally by a certain angle. When the staff controls the second servo motor 23 to work, it drives the worm gear 24 to rotate, which in turn drives the worm wheel 25 to rotate, thereby causing the surveying instrument 2 to rotate through the connecting rod. Then, the surveying instrument 2 rotates clockwise or counterclockwise to achieve the purpose of adjusting the angle again, making the surveying instrument 2 survey a wider range.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
