Drones in Facility Agriculture

Abstract

This invention discloses the application of unmanned aerial vehicles (UAVs) in facility agriculture, including a quick-release interface module pre-installed on the periphery of the lower half of the UAV body. The quick-release interface module specifically includes wing frames mounted on the UAV body and fixed brackets extending outwards along each wing frame. This invention solves the technical problem of rotors easily colliding with the greenhouse roof film during snow removal by incorporating a detachable functional skirt assembly in the lower half, circumferentially arranging pressure relief holes around the skirt's periphery, and a top anti-collision ring. Specifically, the trumpet-shaped skirt concentrates and guides the rotor airflow downwards to form a high-speed airflow column, efficiently blowing away loose snow. Combined with a thickened flexible buffer ring along the lower edge of the skirt and a flexible anti-collision ring at the top, it provides double buffer protection in case of accidental contact. The pressure relief holes balance the internal and external air pressure, preventing the "ground suction effect" during close-to-the-ground flight, significantly improving the safety and feasibility of snow removal operations.

Description

Technical Field

[0001] This invention relates to the field of drone application technology, and more specifically, to the application of drones in facility agriculture. Background Technology

[0002] Currently, drones are being used more and more widely, demonstrating advantages such as labor saving, efficiency, and high effectiveness in agricultural plant protection. However, existing conventional drones face some common technical challenges when directly applied to facility agriculture (such as plastic greenhouses and solar greenhouses): Firstly, snow accumulation on the top of plastic greenhouses in winter must be cleared in a timely manner. However, manual cleaning is inefficient and dangerous. Although drones can attempt to blow snow, their rotors are very likely to collide with the greenhouse film, causing the drone to crash and the film to break.

[0003] Secondly, traditional drones currently rely on onboard batteries, which have short flight times and cannot meet the needs of continuous operation. At the same time, due to the limitations of battery discharge capacity, it is difficult to instantly increase power to enhance wind force when needed.

[0004] Third, currently, a typical drone can only perform a single task, resulting in a large amount of equipment being idle during the off-season for plant protection, which is not economical.

[0005] Fourth, conventional nozzles on the market produce large atomized particles, and due to the turbulent airflow from the drone's downwash, the liquid is difficult to adhere evenly to the back of the blades, and it is easy to cause drift and waste.

[0006] Therefore, there is an urgent need for a dedicated drone operation platform that can solve the above problems safely, efficiently, and at low cost. Summary of the Invention

[0007] To overcome the aforementioned deficiencies in the prior art, embodiments of the present invention provide applications of unmanned aerial vehicles (UAVs) in facility agriculture. By incorporating a detachable functional skirt assembly in the lower half of the UAV and circumferentially arranging pressure relief holes around the skirt's perimeter, along with an upper anti-collision ring at the top, the technical problem of UAV rotors easily colliding with the greenhouse roof film during snow removal, causing crashes and damage, as mentioned in the background art, is solved. Specifically, the trumpet-shaped skirt concentrates and guides the rotor airflow directly downwards to form a high-speed airflow column, efficiently blowing away loose snow. Combined with the thickened flexible buffer ring at the lower edge of the skirt and the flexible anti-collision ring at the top, double buffer protection is provided in the event of accidental contact. The pressure relief holes balance the internal and external air pressure, preventing the "ground suction effect" during close-to-the-ground flight. This ensures that the UAV can safely and stably approach the greenhouse film for operation, significantly improving the safety and feasibility of snow removal operations. Furthermore, continuous power supply via cable enables unlimited time-lapse operation; the constant tension automatic cable retraction unit automatically retracts and extends the cable according to the flight path. This design ensures that the cable neither drags nor tangles the drone; the external power supply allows the drone to overcome battery discharge limitations, instantly drawing upon greater power to enhance wind force and load capacity when needed, meeting the demands of high-load continuous operations such as snow removal; finally, by setting up a quickly replaceable interface for the operating function modules, along with a matching ultrasonic atomizing spraying module, and combining it with replaceable first and second functional skirt components, the design solves the technical problems mentioned in the background art, such as the high idle rate of equipment due to the single function of the drone, and the large atomization particle size of conventional nozzles, making it difficult for the liquid to adhere evenly and easily drifting and wasting the pesticide. Specifically, the quick-release interface allows for rapid switching between snow removal mode and plant protection mode, achieving multi-purpose use and significantly improving the annual utilization rate of the equipment; the micron-sized droplets generated by ultrasonic atomization are evenly blown onto the front and back of the leaves by the stable airflow guided by the skirt, significantly improving the pesticide adhesion and utilization rate, reducing drift and waste, and further enhancing the practicality of the device, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: Regarding the application of unmanned aerial vehicles (UAVs) in facility agriculture, the invention includes a UAV body, characterized in that it further includes: a quick-release interface module, pre-placed on the periphery of the lower half of the UAV body; At least one functional skirt component is detachably mounted to the lower half of the drone body via the quick-release interface module for converging airflow and providing collision protection. Pressure relief holes are arranged circumferentially around the periphery of the functional skirt assembly to balance the internal and external air pressure and prevent the "ground effect" problem during close-to-the-ground flight. The upper anti-collision ring is located on the outer periphery of the top of the drone body and is fixed to the top of the outer periphery of the functional skirt assembly; The operation function module interface is pre-positioned at the bottom of the UAV body for detachable installation of the operation function module; The power supply interface is located on the drone body and is used to connect to an external power source. The external power source provides power for the drone body, the constant tension automatic cable rewinding unit, and the ultrasonic atomizing spraying module.

[0009] Preferably, the functional skirt assembly includes a first functional skirt assembly, which is shaped like a trumpet or a frustum, with its lower edge's horizontal projection completely covering and exceeding the rotation area of ​​all rotors of the UAV body; and a second functional skirt assembly, which is a cylindrical structure with a depth less than that of the first functional skirt assembly, or is simply an annular buffer edge.

[0010] Preferably, the upper anti-collision ring is a flexible inflatable ring structure or a high-density closed-cell foam ring structure, which is fixed to the top of the outer periphery of the first functional skirt assembly.

[0011] Preferably, the external power source includes a ground power unit for outputting DC power; a flexible power cable, one end of which is electrically connected to the ground power unit, and the other end of which is equipped with an anti-drop quick-connect connector that matches the power supply interface; and a constant tension automatic cable rewinding unit for rewinding and unwinding the flexible power cable to maintain constant tension in the cable.

[0012] Preferably, the constant tension automatic winding and unwinding unit includes a winding reel, a tension sensor, and a control motor. The tension sensor detects the cable tension and feeds back a signal, and the control motor drives the winding reel to wind and unwind the cable according to the signal.

[0013] Preferably, the operating function module is an ultrasonic atomizing spraying module, which includes a sealed liquid tank and at least one nozzle with an ultrasonic atomizing plate, the nozzle's mist outlet facing the downward airflow area generated by the UAV's rotor.

[0014] Preferably, the ultrasonic atomizing spraying module is electrically connected to the UAV body through the operation function module interface, and the ultrasonic atomizing spraying module is detachably connected to the bottom of the UAV body.

[0015] Preferably, the quick-release interface module includes a wing frame mounted on the UAV body and a fixing bracket extending outward along each wing frame. A matching fixing block is provided within the fixing bracket, and the fixing bracket and the fixing block are locked together by a fixing knob thread. The fixing bracket and the fixing block are arranged circumferentially along the inner side of the first functional skirt assembly. Through this quick-release interface module, the first functional skirt assembly can be replaced, for example, with a first functional skirt assembly that extends shorter at the lower end, thus not enclosing the lower nozzle and enabling agricultural pesticide spraying operations, resulting in higher economic efficiency.

[0016] Preferably, the functional skirt assembly is made of elastic rubber material or thermoplastic polyurethane elastomer coated fabric.

[0017] Preferably, the lower edge of the first functional skirt assembly is provided with a thickened flexible buffer ring to provide protection when it comes into contact with the greenhouse film or other objects.

[0018] The technical effects and advantages of this invention are as follows: 1. This invention solves the technical problem mentioned in the background art of drones crashing or being damaged when their rotors collide with the greenhouse film during snow removal by setting a detachable functional skirt component in the lower half and arranging pressure relief holes around the periphery of the skirt, while setting an upper anti-collision ring at the top. Specifically, the trumpet-shaped skirt gathers and guides the rotor airflow directly downward to form a high-speed airflow column, which efficiently blows away loose snow. Combined with the thickened flexible buffer ring at the lower edge of the skirt and the flexible anti-collision ring at the top, it provides double buffer protection in case of accidental contact. The pressure relief holes balance the internal and external air pressure and prevent the "ground suction effect" when flying close to the ground, thereby ensuring that the drone can safely and stably approach the greenhouse film for operation, significantly improving the safety and feasibility of snow removal operations.

[0019] 2. This invention solves the technical problems mentioned in the background art, namely, the short flight time and inability to meet the needs of continuous operation due to the reliance on onboard batteries in traditional UAVs, and the difficulty in instantly increasing power to enhance wind power, by setting up a ground power supply system, including a ground power unit, a flexible power cable, and a constant tension automatic cable retraction unit. Specifically, the invention continuously supplies power to the UAV through the cable, enabling unlimited time-lapse operation; the constant tension automatic cable retraction unit automatically retracts and extends the cable according to the flight path, ensuring that the cable neither drags the UAV nor gets tangled; the external power supply enables the UAV to overcome the limitations of battery discharge and instantly call upon greater power when needed to enhance wind power and load capacity, meeting the needs of high-load continuous operations such as snow removal.

[0020] 3. This invention solves the technical problems mentioned in the background art, such as the high idle rate of drones due to their single function, and the large atomization particle size of conventional nozzles, which makes it difficult for pesticides to adhere evenly and easily drift and waste, by setting up a quick-release interface for the operation function module and matching it with an ultrasonic atomization spraying module, combined with replaceable first and second functional skirt components. Specifically, the quick-release interface allows for rapid switching between snow removal mode and plant protection mode, realizing multiple uses for one machine and greatly improving the annual utilization rate of the equipment; the micron-sized droplets generated by ultrasonic atomization are evenly blown onto the front and back of the leaves by the stable airflow guided by the skirt, which significantly improves the pesticide adhesion rate and utilization rate and reduces drift and waste.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] As attached Figures 1 to 4 The image shown is of a drone application for facility agriculture, configured in snow removal mode. The platform includes a drone body 1, which is a multi-rotor drone with multiple outward-extending wing frames 11, each wing frame 11 having a rotor at its end.

[0025] For details regarding the structure of the quick-release interface module, please refer to [link / reference needed]. Figure 2 and Figure 3 As shown, the quick-release interface module is pre-positioned on the periphery of the lower half of the UAV body 1. In this embodiment, the quick-release interface module specifically includes: a wing frame 11 set on the UAV body 1, and a fixing bracket 12 extending outward along each wing frame 11. The fixing bracket 12 is provided with a matching fixing block 13. The fixing bracket 12 and the fixing block 13 are locked together by a fixing knob 14. The fixing bracket 12 and the fixing block 13 are evenly arranged along the inner circumferential side of the first functional skirt assembly 21. Through this structure, the operator can lock and unlock the fixing block 13 and the fixing bracket 12 by tightening or loosening the fixing knob 14, thereby realizing the quick assembly and disassembly of the functional skirt assembly 2.

[0026] In snow removal mode, please combine Figure 2 and Figure 3As shown, the device includes a functional skirt assembly 1, and its functional skirt assembly 2 is selected from the first functional skirt assembly 21. The first functional skirt assembly 21 has a trumpet-shaped or frustum-shaped structure with a smaller top and a larger bottom. It is made of elastic rubber material or thermoplastic polyurethane elastomer coated cloth, which has a certain elasticity and moderate softness and hardness. The first functional skirt assembly 21 is detachably installed on the lower half of the UAV body 1 through the quick-release interface module. Its upper edge is fixedly connected to the fixing block 13, and its lower edge extends downward. The horizontal projection of its lower edge completely covers and is larger than the rotation area of ​​all rotors of the UAV body 1, thereby covering all rotors and forming a fairing structure. The lower edge port of the first functional skirt assembly 21 is provided with a thickened flexible buffer ring 23. The thickened flexible buffer ring 23 is made of elastic material and plays a buffering and protective role when in contact with the film or other objects.

[0027] Among them, such as Figure 1 As shown, multiple pressure relief holes 8 are arranged circumferentially along the outer periphery of the first functional skirt assembly 21. The pressure relief holes 8 are through holes that penetrate the side wall of the skirt. Their function is to balance the air pressure inside and outside the skirt when the UAV is close to the ground or the roof, to prevent the "ground effect" or "ground suction effect" caused by the rapid change of air pressure inside the skirt, and to ensure the stability of the UAV's flight attitude.

[0028] Regarding the upper anti-collision ring structure and its installation, please refer to... Figure 1 and Figure 2 As shown, the upper anti-collision ring 3 is located on the outer periphery of the top of the UAV body 1, specifically fixed to the top of the outer periphery of the first functional skirt assembly 21. In this embodiment, the upper anti-collision ring 3 is a flexible inflatable ring structure made of PVC inflatable ring, which does not affect the rotor air intake and can play the role of top anti-collision. In other embodiments, the upper anti-collision ring 3 can also adopt a high-density closed-cell foam ring structure.

[0029] For details regarding the ground power supply system, please refer to [link / reference needed]. Figure 1 and Figure 4 As shown, in this embodiment, the drone platform adopts a ground-based power supply method to solve the endurance problem. The ground power supply system includes: Ground power unit 4: Located on the ground, it can be a portable generator or a large-capacity battery pack, with a built-in voltage conversion and rectification module for outputting DC power adapted to the UAV.

[0030] Flexible power supply cable 5: It is a lightweight, highly flexible multi-core sheathed cable with a certain tensile strength. One end of it is electrically connected to the ground power unit 4, and the other end is equipped with an anti-drop quick connector 51, which is compatible with the power supply interface set on the UAV body 1.

[0031] Constant tension automatic cable retraction unit 6: Used for retracting and extending flexible power supply cable 5, ensuring the cable maintains constant tension at all times, specifically as follows... Figure 1and Figure 4 As shown, the constant tension automatic take-up and release unit 6 includes a winding reel 61, a tension sensor 62, and a control motor 63. The flexible power cable 5 is wound on the winding reel 61. The tension sensor 62 is used to detect the tension of the cable in real time and feed back an electrical signal. The control motor 63 drives the winding reel 61 to perform take-up or release operations according to the received signal, ensuring that the cable neither drags the drone nor gets tangled due to excessive slack during the drone's flight.

[0032] The operation function module interface is pre-installed at the bottom of the drone body 1. It is a standardized quick-release physical interface and electrical interface for detachable installation of the operation function module. In snow removal mode, no operation module is installed on this interface to reduce weight. For example, the operation function module can be connected to the drone body 1 by a locking connection, a bayonet connection or a bolt connection.

[0033] The working principle of the above embodiment 1 is as follows: In snow removal mode, the operator first installs the first functional skirt assembly 21 onto the drone body 1 via the quick-release interface module, fixes the upper anti-collision ring 3 to the top of the skirt, then inserts the anti-drop quick-connect connector 51 of the flexible power cable 5 into the drone's power interface, starts the ground power unit 4 and the constant tension automatic cable retraction unit 6, sets the tension parameters, and operates the drone to fly to the top of the greenhouse, flying close to the roof at a low altitude and slow speed. The first functional skirt assembly 21 gathers and guides the downwash airflow generated by the rotor directly downwards, forming a concentrated high-speed airflow column that effectively blows away the floating snow on the roof. The pressure relief hole 8 balances the internal and external air pressure to prevent suction to the ground, the thickened flexible buffer ring 23 protects the greenhouse film in case of accidental contact, the upper anti-collision ring 3 prevents the top of the fuselage from colliding with the roof beam, and the constant tension automatic cable retraction unit 6 automatically retracts and extends the cable according to the drone's flight path to ensure that the cable is always at the optimal slack.

[0034] Example 2: Configuration in facility-based plant protection mode, please refer to [link / reference]. Figure 2 As shown, this embodiment provides the configuration status of the drone operation platform in the plant protection mode within the facility.

[0035] In plant protection mode, the operator can disassemble the first functional skirt component 21 and replace it with the second functional skirt component 22 through the quick-release interface module. The second functional skirt component 22 is a cylindrical structure with a depth less than that of the first functional skirt component 21. In this embodiment, it is a shallow cylindrical shape, retaining only the basic functions of guiding flow and anti-collision. It is also installed through the cooperation of the fixing block 13 and the fixing seat 12.

[0036] The upper anti-collision ring 3 remains fixed to the top of the outer perimeter of the second functional skirt assembly 22, continuing to perform the top anti-collision protection function.

[0037] In plant protection mode, an ultrasonic atomizing spraying module 7 is installed through the operation function module interface at the bottom of the UAV body 1. The ultrasonic atomizing spraying module 7 includes a sealed liquid tank 71 and at least one nozzle 72 with an ultrasonic atomizing plate. The nozzle 72's mist outlet faces the downward airflow area generated by the rotor of the UAV body 1. That is, the nozzle 72 is positioned so that the atomized liquid can be drawn into the rotor airflow and blown downward. At the same time, the ultrasonic atomizing spraying module 7 is electrically and mechanically connected to the UAV body 1 through the operation function module interface, and can be quickly disassembled and assembled.

[0038] At the same time, similar to Example 1, this example still uses a ground power supply system to power the drone to ensure the needs of long-term operation.

[0039] Example 2: Working principle of plant protection mode In plant protection mode, the drone flies at a constant speed about 0.5-1 meter above the crops. The ultrasonic atomizing spraying module 7 vibrates the liquid pesticide into micron-sized room-temperature droplets. After the droplets are sprayed from the nozzle 72, they are entrained by the downward airflow generated by the rotor and guided by the second functional skirt component 22 to form a stable and uniform downward airflow. This forces the droplets to penetrate into the middle and lower layers of the crops and the back of the leaves, achieving efficient and precise pesticide application. The shallow cylindrical structure of the second functional skirt component 22 provides a certain airflow guidance function without adding too much weight and flight drag, making the drone more flexible in the narrow space of the facility.

[0040] Example 3: Further optimization under the plant protection model This embodiment provides the configuration status of the UAV operation platform in the field plant protection mode (not shown in the figure).

[0041] When operating in open fields, no collision protection is required. Operators can completely disassemble the first functional skirt component 21 or the second functional skirt component 22 through the quick-release interface module, leaving only the basic shape of the UAV body 1. At the same time, the ground power supply system is removed and replaced with a high-capacity airborne battery to achieve autonomous flight. The ultrasonic atomizing spraying module 7 is still installed on the bottom of the UAV for spraying operations.

[0042] Because the skirt has been removed to reduce its own weight, the drone flies more stably, and the payload and flight time are maximized, making it suitable for large-scale field plant protection operations and further improving the applicability of the equipment.

[0043] It should be noted that in the above embodiments, both the first functional skirt assembly 21 and the second functional skirt assembly 22 can be made of elastic rubber material or thermoplastic polyurethane elastomer coated cloth, which has both elasticity and toughness. The upper anti-collision ring 3 can be made of PVC inflatable ring or high-density closed-cell foam. The fixing bracket 12, fixing block 13, and fixing knob 14 can be made of lightweight high-strength engineering plastic or aluminum alloy material to ensure connection strength while controlling weight. At the same time, the control motor 63 of the constant tension automatic cable reeling unit 6 is preferably connected to the UAV flight control system. The flight control system calculates the flight speed and direction of the UAV in real time based on GPS positioning data, radar ranging data or preset flight path, and sends cable reeling and releasing commands to the control motor 63 to achieve matching of cable reeling and releasing speed with flight speed, ensuring that the cable is always in the optimal slack state.

[0044] In summary, this invention achieves a detachable connection between the functional skirt assembly 2 and the drone body 1 through a quick-release interface module, solves the air pressure balance problem through a pressure relief hole 8, provides top protection through an upper anti-collision ring 3, solves the endurance problem through a ground power supply system, and achieves efficient plant protection through an ultrasonic atomizing spraying module 7. All components cooperate and work together, enabling the same drone platform to quickly switch between different operating modes, meeting the diverse operational needs of facility agriculture.
