Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a portable pest and disease detection drone. Background Technology

[0002] With the development of modern agriculture, early detection and precise control of pests and diseases have become crucial for ensuring crop yield and quality. Traditional pest and disease monitoring mainly relies on manual field inspections or fixed-point sensor monitoring, which suffers from low efficiency, limited coverage, slow response speed, and high labor costs, making it difficult to meet the real-time monitoring needs of large areas of farmland or complex terrain.

[0003] In recent years, the application of drone technology in agriculture has become increasingly widespread, especially in areas such as pesticide spraying and remote sensing mapping, where it has achieved remarkable results. Invention patent CN114313260A discloses a forestry pest and disease detection drone, which, with the cooperation of a camera, main control unit, and positioning unit, can mark pest and disease areas with paint. However, the rotor used is fixed to the drone body and cannot be stored. Existing agricultural drones are mostly operational in nature. Many pest and disease monitoring devices are large and complex, unsuitable for flexible deployment in small-scale farmland, orchards, or mountainous environments, limiting their use in diverse planting scenarios. Most are fixed installations, lacking portability and failing to meet the needs of researchers and plant protection station staff for mobile surveys and temporary deployments. There is a lack of integrated, miniaturized, and portable dedicated monitoring equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a portable pest and disease detection drone that can be quickly unfolded and folded during operation, improving the portability and ease of operation of the equipment. By combining it with a high-speed camera and an infrared scanner, it can achieve efficient detection and data collection of pest and disease areas.

[0005] This utility model provides the following technical solution:

[0006] A portable pest and disease detection drone includes a body, a camera, an infrared scanner, a flight mechanism, and a locking mechanism;

[0007] The camera and the infrared scanner are respectively mounted on the surface of the machine body;

[0008] The flight mechanism includes a drive assembly and a fixed ring. The drive assembly is mounted on the fixed ring, and the fixed ring is rotatably connected to the fuselage to enable the flight mechanism to unfold and fold.

[0009] The locking mechanism includes a limiting plate and a locking assembly. The limiting plate is fixed to the fuselage, and the locking assembly is installed on the limiting plate to lock the flight mechanism in both unfolded and folded states.

[0010] Furthermore, the drive assembly includes a drive motor and blades, with the drive motor mounted on the fixed ring and the blades mounted on the output shaft of the drive motor.

[0011] Furthermore, the locking assembly includes a screw and a knob, the knob being mounted on the screw, and the fixing ring and the limiting plate having threaded holes corresponding to the position of the screw. In the deployed state of the flight mechanism, the screw passes through the threaded hole of the limiting plate and connects with the threaded hole of the fixing ring, thereby locking the flight mechanism in the deployed state.

[0012] Furthermore, the fixing ring is also provided with a slot that matches the screw. When the flight mechanism is folded, the screw passes through the threaded hole of the limiting plate and engages with the slot to lock the flight mechanism in the folded state.

[0013] Furthermore, it also includes a liquid storage mechanism, which includes a liquid storage tank, a liquid inlet pipe, a sealing cap, a liquid delivery pipe, a liquid pump, and a nozzle. The liquid storage tank and the liquid inlet pipe are embedded in the body. The top of the liquid storage tank is connected to the liquid inlet pipe. The sealing cap is installed at the open end of the liquid inlet pipe. The liquid storage tank is connected to the liquid delivery pipe. The liquid delivery pipe is connected to the liquid pump. The liquid pump is connected to the nozzle.

[0014] Furthermore, the surface of the liquid storage tank is a transparent plate.

[0015] Furthermore, it also includes a battery, which is installed inside the body and connected to a charging connector.

[0016] Furthermore, it also includes a charging protection mechanism, which includes a connector and a protective cover. One end of the connector is fixed to the battery, and the other end is connected to the protective cover. The protective cover is inserted into the charging connector.

[0017] Furthermore, a bracket is provided at the bottom of the machine body, and a support is installed on the bracket.

[0018] Furthermore, the support is provided with anti-slip material and the support is made of rubber.

[0019] Furthermore, the machine body is equipped with a humidity sensor.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. The cooperation between the flight mechanism and the locking mechanism enables the rapid deployment and folding of the drone's wings, as well as the locking of the deployed and folded states, improving the portability and ease of operation of the equipment; the drive motor drives the blades to rotate at high speed, providing stable lift and ensuring smooth and reliable flight; the camera and infrared scanner enable efficient monitoring and data collection of forest pests and diseases.

[0022] 2. This utility model is equipped with a liquid storage mechanism. When the camera detects pests, the operator can inject an appropriate amount of insecticide into the liquid storage tank through the liquid inlet pipe and observe the amount of pesticide injected through the transparent plate to ensure that the pesticide addition is safe and controllable. After the liquid pump is started, the insecticide is delivered to the nozzle through the liquid delivery pipe for directional spraying, which effectively improves the control efficiency and reduces pesticide waste and environmental pollution.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment provides a portable pest and disease detection drone, including a body 1, a camera 3, an infrared scanner 4, a flight mechanism, a locking mechanism, and a humidity sensor 5.

[0035] like Figure 1 As shown, a camera 3 is mounted on the middle of the side of the body 1 by screws. In this embodiment, the camera 3 is a high-definition camera. An infrared scanner 4 is mounted on the side of the body 1 by screws, and a temperature sensor 5 is mounted on the top of the body 1 by screws.

[0036] The flight mechanism includes a drive assembly and fixed rings 8. The drive assembly includes a drive motor 9 and blades 10. In this embodiment, the drive motor 9 is a brushless motor. There are two fixed rings 8, which are rotatably connected to the two sides of the body 1, respectively, to realize the unfolding and folding of the flight mechanism. The drive motor 9 is installed on the side of the two fixed rings 8 that is far apart from each other. Specifically, the drive motor is installed in the middle position of each fixed ring 8 by screws. The output shaft of each drive motor 9 is connected to a blade 10 by a coupling.

[0037] The locking mechanism includes a limiting plate 7 and a locking assembly. There are two limiting rods 7, which are respectively welded to both sides of the lower part of the body 1 and respectively abut against the fixing ring 8 on the same side; there are also two locking assemblies, which are respectively installed on the limiting plates 7 on both sides to lock the flight mechanism in the unfolded and folded states.

[0038] Specifically, the locking assembly includes a screw 11 and a knob 12. The knob 12 is fused to the lower part of the screw 11. The screw 11 is an M10 screw with a pitch of 1.5 mm (standard coarse thread) and a self-locking torque of approximately 0.69 N·m, providing a self-locking function. The screws 11 on both sides can be threadedly connected to the middle of the limiting rods 7 on both sides of the body 1. The two fixing rings 8 also have threaded holes corresponding to the positions of the screws 11. The two screws 11 can be threadedly connected to the corresponding fixing rings 8 through the threaded holes. The fixing rings 8 also have slots 23 that match the screws 11. The screws 11 cooperate with the slots 23 and the threaded holes on the limiting rods 7 to achieve locking of the flight mechanism in the folded state.

[0039] like Figure 2 As shown, the portable pest detection drone provided in this embodiment also includes a battery 13, a bracket 2 and a support 6. The battery 13 is installed on the body 1 by screws. The bracket 2 is installed on the front and rear sides of the bottom of the body 1 by screws. Each bracket 2 is fixedly fitted with a support 6 at the bottom. Both supports 6 are anti-slip supports and are made of rubber.

[0040] The working process and working principle of the portable pest and disease detection drone provided in this embodiment are as follows:

[0041] In this embodiment, the portable pest and disease detection drone measures 8 cm (height) × 5 cm (width) in its folded state and is expected to measure approximately 8 cm (height) × 18 cm (width) when unfolded, making it easy to carry while also meeting the requirements for flight stability. The bare drone weighs 200 grams, and the battery 13 is an 11.1V / 1500 mAh battery weighing 120 grams. When taking off for a mission, the portable pest and disease detection drone weighs 350 grams.

[0042] Before the drone performs its work, the operator first checks whether all components of the drone are securely installed, especially the connection status of the camera 3, infrared scanner 4, drive motor 9 and blades 10. After confirming that the battery 13 has sufficient power, the drone can start its work.

[0043] like Figure 1 As shown, the drone is in a folded state for easy carrying. To take off, rotate knob 12 to disengage screw 11 from retaining ring 8, allowing retaining ring 8 to rotate 90 degrees and unfold. Then, reverse knob 12 to screw screw 11 into the threaded hole of retaining ring 8, thus securing retaining ring 8 and completing the unfolded state of the drone's flight mechanism. Figure 2 As shown.

[0044] Then, a start command can be sent via a remote control device to activate the drive motor 9, which drives the blades 10 to rotate at high speed, generating enough lift to overcome the drone's own weight and make it rise steadily from the ground. The camera 3 and infrared scanner 4 are started simultaneously to begin collecting real-time images of trees and temperature information.

[0045] During flight, images captured by camera 3 are transmitted back to the ground station for analysis, while infrared scanner 4 continuously monitors changes in tree surface temperature, searching for abnormal hotspots that may indicate areas with pests and diseases. After completing the monitoring task, the operator can use the remote control to slowly descend the drone to a safe landing point. Support 6 ensures a smooth landing for the drone, preventing tipping or damage due to uneven ground. Turning knob 12 clockwise disengages screw 11 from the rotation hole of the limit rod, allowing the fixing ring 8 to rotate 90 degrees and retract. After retraction, turning knob 12 counterclockwise causes screw 11 to rotate and move upwards. At this point, screw 11 can lock into the slot 23 of fixing ring 8, preventing it from rotating further. The drone's flight mechanism is now in a folded state.

[0046] During the flight mission of the portable pest and disease detection drone, the humidity sensor 5 continuously monitors the changes in air humidity along the flight path. Combined with the data from the camera 3 and the infrared scanner 4, the operator can use existing statistical analysis methods to generate a more comprehensive forest health assessment report. For example, high humidity areas may be at risk of fungal infection, and the data provided by the humidity sensor 5 helps to accurately locate these areas.

[0047] In this embodiment, the cooperation between the flight mechanism and the locking mechanism enables the rapid unfolding and folding of the UAV flight mechanism, as well as the locking of the unfolded and folded states, improving the portability and ease of operation of the equipment; the high-speed rotation of the blades by the drive motor provides stable lift, ensuring smooth and reliable flight; the cooperation of the camera, infrared scanner and humidity sensor enables efficient monitoring, data collection and data evaluation of forest pests and diseases, effectively improving the accuracy of pest and disease identification.

[0048] Example 2

[0049] This embodiment provides a portable pest and disease detection drone, which includes the structure in Embodiment 1, and also includes a liquid storage mechanism and a charging protection mechanism.

[0050] like Figures 3-4As shown, the charging protection mechanism includes a connector 14 and a protective cover 15. A battery 13 is installed inside the body 1 by screws. A charging connector 1301 is installed on the lower side of the battery 13 by screws. The connector 14 is glued to the side of the battery 13. In this embodiment, the connector 14 is a connecting rope. The lower end of the connector 14 is glued to the protective cover 15. The protective cover 15 can be inserted into the charging connector 1301.

[0051] like Figure 5 As shown, the liquid storage mechanism includes a liquid storage tank 16, an inlet pipe 22, a sealing cap 17, a transparent plate 21, an infusion pipe 18, a liquid pump 19, and a nozzle 20. The liquid storage tank 16 and the inlet pipe 22 are embedded and fixedly connected to both sides of the body 1, respectively. The tops of the two liquid storage tanks 16 are respectively connected to and communicate with the inlet pipe 22. The top openings of the two inlet pipes 22 are respectively equipped with sealing caps 17. The right side of the two liquid storage tanks 16 is fixedly connected to the transparent plate 21 by glue. In this embodiment, the transparent plate 21 is made of glass. The infusion pipe 18 is connected between the two transparent plates 21. The liquid pump 19 is connected to the infusion pipe 18. The nozzle 20 is connected to the liquid pump 19.

[0052] Based on the working process and principle of the portable pest and disease detection drone in Example 1, the portable pest and disease detection drone provided in this example also has the following working process and principle:

[0053] Before the drone takes off, the operator can pull out the sealing cap 17 from the liquid inlet pipe 22 and pour the insecticide into the storage tank 16 through the liquid inlet pipe 22. Since the transparent plate 21 is made of glass, the operator can check the dosage of insecticide poured into the storage tank 16 through the transparent plate 21 to ensure that the dosing is safe and controllable. When two-thirds of the liquid is poured in, stop pouring and put the sealing cap 17 back in place.

[0054] During flight missions, when camera 3 captures images of obvious pests on the tree surface, the liquid pump 19 can be activated via remote control. The liquid pump 19 draws the insecticide from the storage tank 16 into the delivery pipe 18, which then flows through the liquid pump 19 and is sprayed out from the nozzle 20. This allows for the spraying of insecticide to the pest-prone area to prevent pest infestation. After the liquid pump 19 is activated, the insecticide is delivered through the delivery pipe 18 to the nozzle 20 for targeted spraying, effectively improving control efficiency and reducing pesticide waste and environmental pollution.

[0055] When the drone needs to be charged, the operator first removes the protective cover 15. Since the protective cover 15 is fixed to the battery 13 by the connector 14, it will not be lost and effectively prevents moisture and dust from entering, extending its service life. The external charger plug is then inserted into the charging connector 1301 to start the charging process. The charging connector 1301 is compact and well-sealed, facilitating quick connection to an external power source and improving operational convenience and maintenance efficiency. After charging is complete, the dust cover 15 is reinserted into the charging connector 1301 to ensure that the charging connector 1301 is clean and dry for the next use.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
