[0001] The present invention relates to the technical field of agricultural monitoring equipment, and in particular to an unmanned aerial vehicle system for agricultural monitoring. Background Art

[0002] With the continuous advancement and development of drone technology, drones are increasingly used in the agricultural field. Drones can carry cameras and other equipment to monitor pests and diseases in farmland in real time, thereby helping farmers to find and deal with problems in a timely manner and improve the yield and quality of crops. However, there are some problems with the drone storage boxes commonly found on the market, which limits the application effect of drones in agriculture.

[0003] First, the current drone storage box has a single structure and cannot meet the needs of outdoor work. In an agricultural environment, drones often need to be operated in the fields, which requires the storage box to have good portability. However, existing storage boxes are often bulky and heavy, and cannot be easily carried to the fields, which brings inconvenience to farmers.

[0004] Secondly, the existing drone storage box has a single function and cannot be used as an operating table. During agricultural monitoring, farmers need to control and adjust the drone in real time, which requires a stable operating platform. However, the existing storage box is just a simple container and cannot provide a stable operating platform, which brings inconvenience to farmers' operation.

[0005] Based on this, in order to further improve the applicability of existing UAV systems, we propose a UAV system for agricultural monitoring. Summary of the invention

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-7 , a drone system for agricultural monitoring, specifically the drone system comprises a bottom frame 1 and a storage box 2 accommodated inside the bottom frame 1, and a lifting mechanism 3 is arranged between the bottom frame 1 and the storage box 2; The storage box 2 includes a bottom box 21 and a box cover 22 pinned to the bottom box 21. In this embodiment, a hydraulic rod can be pinned to the top side of the bottom box 21, and the telescopic end of the hydraulic rod is pinned to the box cover 22, so that the box cover 22 can be opened conveniently; A placement plate 23 is movably connected to the inner side of the bottom box 21, and a drone 4 is placed on the end face of the placement plate 23. In this embodiment, a camera is also connected to the drone 4, and pests and diseases in the farmland are monitored by the drone 4. A clamping structure 5 for clamping the drone 4 is also provided on the end face of the placement plate 23. A pushing member 24 for pushing the placement plate 23 is installed on the inner side of the box cover 22. Specifically, the pushing member 24 in this embodiment is a rod fixed on the inner side of the box cover 22. When the box cover 22 is closed with the bottom box 21, the pushing member 24 in the box cover 22 resists the placement plate 23 and moves downward to realize the movement drive of the placement plate 23.

[0022] In some embodiments, the clamping structure 5 in the present invention includes two sliding rods 51, and two sliding grooves 52 are provided on the end surface of the placement plate 23. The two sliding rods 51 slide in the two sliding grooves 52 respectively, and a clamping block 53 is fixedly installed on the top of the sliding rod 51. Specifically, in this embodiment, the design of two relatively sliding sliding rods 51 is adopted to clamp the two sides of the drone 4, so as to ensure the stability of the drone 4 when it is stored.

[0023] On the basis of the above-mentioned embodiment, in order to realize the synchronous clamping movement of the two slide bars 51, in this embodiment, the bottom of the placement plate 23 is rotatably connected with a shaft 54, and a torsion spring 55 is fixedly connected between the shaft 54 ​​and the placement plate 23; A rotating plate 56 is fixedly connected to the bottom of the shaft rod 54 , and connecting rods 57 are pin-connected to both ends of the rotating plate 56 , respectively. The other end of the connecting rod 57 is pin-connected to the sliding rod 51 .

[0024] That is to say, when a slide bar 51 is moving, since the two ends of the rotating plate 56 are rotationally connected to the connecting rod 57, and the connecting rod 57 is also rotationally connected to the slide bar 51, when a slide bar 51 moves, the rotation of the rotating plate 56 will drive the two slide bars 51 to move synchronously relative to each other, so as to achieve clamping of the drone 4 and improve the convenience of the clamping operation.

[0025] It should be noted that in order to realize the automatic movement of the control slide bar 51 during the downward movement of the placement plate 23 in the present invention, a wedge block 58 is fixedly installed on the inner side of the bottom box 21 in this embodiment, and the bottom end of the slide bar 51 is in contact with the wedge block 58.

[0026] That is, during specific use, when the drone 4 needs to be stored, the drone 4 is first placed on the placement plate 23. Thereafter, when the box cover 22 is closed, the pusher 24 on its inner side surface will resist the placement plate 23 and move downward. When the placement plate 23 moves downward, the slide bar 51 on the placement plate 23 will resist the inclined surface of the above-mentioned wedge block 58, so that the slide bar 51 will move along the drive of the inclined surface. At the same time, the two slide bars 51 achieve relative synchronous movement under the control of the rotating plate 56, so as to achieve the clamping of the drone 4, that is, when the bottom box 21 and the box cover 22 are closed, the downward movement of the placement plate 23 and the fixing operation of the drone 4 can be completed at the same time.

[0027] On the basis of the above embodiment, in order to realize that the placement plate 23 is automatically pushed outward when the cover is opened, a compression spring 59 is fixedly connected between the bottom of the placement plate 23 and the bottom of the bottom box 21 in the present invention. Through the design of the compression spring 59, when the box cover 22 is opened, the placement plate 23 can be quickly pushed outward under the push of the compression spring 59, and at the same time, when the slide bar 51 is reset, the clamping of the drone 4 can be released, thereby improving the convenience of taking the drone 4; In addition, in the present invention, a stop plate 25 is rotatably connected to the upper end surface of the placement plate 23, and at least a portion of the stop plate 25 is stopped at the top side of the bottom box 21. In the present invention, the stop plate 25 is designed to stop and fix the placement plate 23 in its upward position when it moves upward, thereby preventing the placement plate 23 from being pressed and moved. At this time, since the downward position of the placement plate 23 is limited, the placement plate 23 can be used as a platform to improve the convenience of flight control of the drone 4.

[0028] In some embodiments, the lifting mechanism 3 in the present invention is a scissor mechanism; One end of the bottom of the scissor mechanism is rotatably connected to the bottom frame 1, and the other end is slidably connected to the bottom frame 1; One end of the top of the scissor mechanism is pin-connected to the side of the bottom box 21 , and the other end is slidably connected to the side of the bottom box 21 .

[0029] On the basis of the above-mentioned embodiment, a guide shaft 31 is fixedly installed on the sliding end at the top of the scissor mechanism in the present invention, and a guide frame 32 is provided on the side of the bottom box 21; The inner side of the guide frame 32 is provided with a guide groove 33 slidably matched with the guide shaft 31 , and the front side is provided with a plurality of positioning holes 34 . The end surface of the guide shaft 31 is embedded with a positioning glass bead 35 , and the telescopic end of the positioning glass bead 35 is engaged with the positioning hole 34 .

[0030] That is, in this embodiment, a guide shaft 31 is fixedly installed at the top movable end of the scissor mechanism, and the guide shaft 31 is slidably adapted with the guide groove 33 on the guide frame 32 to ensure that the scissor mechanism can achieve normal telescopic movement. At the same time, in order to adjust the telescopic position, in this embodiment, a positioning glass bead 35 is embedded at the end of the guide shaft 31, and the positioning glass bead 35 is engaged with the positioning hole 34 to complete the fixing of the telescopic state of the scissor mechanism. The operation is simple and convenient, and the convenience of adjusting the height of the storage box 2 is improved; The above takes the connection between the storage box 2 and the scissor-type mechanism as an example. In further embodiments, the bottom frame 1 may also be connected to the scissor-type mechanism using the same structure. The specific structure may refer to the above description and will not be elaborated here.

[0031] It should be noted that, in this embodiment, two lifting mechanisms 3 are provided on both sides of the bottom box 21 .

[0032] Furthermore, two wheels 11 are provided on the side of the bottom frame 1, and a U-shaped pull rod 12 is movably inserted on the side away from the wheel 11. Specifically, the inner side of the U-shaped pull rod 12 described in this embodiment has a bending portion, and the bending portion abuts against the inside of the bottom frame 1 to prevent the U-shaped pull rod 12 from slipping. Specifically, in this embodiment, by adopting the design of the wheel 11 and the U-shaped pull rod 12, the storage box 2 can be conveniently moved and driven when the storage box 2 is stored, thereby improving the portability of the entire drone system.

[0033] It should be noted that in the embodiment of the present invention, the bottom box 21 and the box cover 22 are connected by a locking assembly, and a storage bag 26 is also installed on the inner side of the box cover 22. The storage bag 26 can be used to store accessories such as the remote control to ensure that the entire drone system can be stored and carried when working outdoors. In summary, the present invention adopts the method of storing the drone 4 inside the storage box 2 to improve the portability and convenience of the entire drone system. At the same time, a retractable structure design is adopted between the storage box 2 and the bottom frame 1. When performing video inspection of farmland outdoors, the entire storage box 2 can be raised and the placement plate 23 inside it can be fixed to use the entire storage box 2 as an operating table, thereby further improving the applicability of work during farmland inspection. In addition, the present invention also provides a clamping structure 5 for the drone 4, which greatly improves the fixing stability of the drone 4 during storage and ensures the stable storage of the entire system.

[0034] 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.
