Description

Technical Field

[0001] This utility model belongs to the field of monitoring drone technology, specifically relating to a forestry pest and disease monitoring drone. Background Technology

[0002] Forest pests and diseases are among the major disasters affecting my country's forests. They possess the severe harm and destructive power of floods and fires, but also exhibit the unique characteristics of biological disasters and the long-term, arduous nature of their management. Monitoring and control of forest pests and diseases are crucial components of the national disaster reduction project and forestry work. Vigorously carrying out forest pest and disease control is of great significance for consolidating afforestation achievements, protecting forest resources, and promoting ecological environment construction and sustainable economic and social development.

[0003] Patent application number 202022246642.3 discloses a drone for monitoring forestry pests and diseases. Through a photographing device and an insect-attracting device, the drone uses an insect-attracting lamp to lure pests from the surrounding environment to an insect-attracting box. An insecticidal electric grid then knocks the pests down into a trapping chamber at the bottom of the box. Insecticide in the trapping chamber further treats the pests, preventing escape and facilitating sampling. The drone can also be used to develop specific pest control plans based on the habits of the pests in the monitored environment. Simultaneously, the photographing device can capture images of the pests' distribution and morphology, enabling targeted treatment and improving the effectiveness of forestry pest and disease control.

[0004] However, the insect-attracting device used in this device is installed directly on the bottom of the drone. However, when the drone is flying, the bottom of the drone generates a large wind, which prevents the pests from entering the interior of the insect-attracting device. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a forest pest and disease monitoring drone. This forest pest and disease monitoring drone aims to solve the technical problem that when the drone is flying, the bottom of the drone will generate a large wind force, which will prevent pests from entering the insect trap.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a forestry pest and disease monitoring drone, which includes a drone body and a mounting frame fixed to the bottom of the drone body. A winding rod is rotatably installed in the mounting frame, and a lead screw is installed on the inner wall of the mounting frame. A connecting line is fixedly wound on the winding rod, and an insect-attracting box is fixed to the bottom end of the connecting line. A mechanism for moving the connecting line is adjustablely installed on the lead screw, and the lead screw rotates synchronously with the winding rod through a meshing mechanism.

[0009] When using this technical solution, a mounting frame is fixed to the bottom of the drone body. The winding rod in the mounting frame, connected by a connecting line, positions the insect-attracting box below the drone body, thus keeping the insect-attracting box away from the drone. This significantly reduces the impact of wind on insect flight and improves the sampling effect of the insect-attracting box on insect samples. A lead screw and sliding tube are installed in the mounting frame. After the motor starts, it drives the winding rod to rotate, winding the connecting line. The guide plate at the bottom of the sliding tube positions the connecting line. Simultaneously, the winding rod synchronously drives the lead screw to rotate slowly, causing the sliding tube and guide plate to move synchronously. During this movement, the connecting line is pushed along the surface of the winding rod, allowing long-distance connecting lines to be evenly wound onto the winding rod. This facilitates even winding of the connecting line and avoids situations where the mounting frame cannot accommodate long-distance connecting lines. After winding, the insect-attracting box is embedded in the receiving hole, and the magnetic plate at the top of the insect-attracting box is attracted and fixed to the magnetic metal plate, preventing it from falling downwards due to the weight of the insect-attracting box after the motor is turned off.

[0010] Preferably, the mounting bracket has a receiving hole at its bottom end, and both ends of the mounting bracket have inlet slots that communicate with the receiving hole.

[0011] Furthermore, magnetic metal plates are fixed on both sides of the inner wall of the receiving hole, multiple through slots are opened on the outer wall of the insect-attracting box, and magnetic plates that are attracted and fixed to the magnetic metal plates are fixed on both sides of the top surface of the insect-attracting box.

[0012] Furthermore, a motor is fixedly mounted on the outer wall of the mounting frame, and the drive shaft of the motor is fixedly connected to the winding rod.

[0013] Furthermore, the meshing mechanism includes a first gear fixedly sleeved on the winding rod and a second gear fixedly sleeved on the lead screw. The first gear and the second gear are meshed together, and baffles are fixedly sleeved at both ends of the winding rod.

[0014] Furthermore, the moving mechanism includes a sliding tube and an L-shaped guide plate fixed to the bottom end of the sliding tube, the sliding tube being threaded onto the lead screw.

[0015] Furthermore, the top wall of the mounting bracket is provided with a sliding groove, and the top end of the sliding tube is fixed with a sliding rod that fits into the sliding groove.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a mounting frame fixed to the bottom of the drone body. The retractable rod in the mounting frame, connected by a wire, positions the insect-attracting box below the drone body, thus keeping the insect-attracting box away from the drone. This significantly reduces the impact of wind on the insects' flight and improves the sampling effect of the insect-attracting box on insect samples.

[0019] By incorporating a lead screw and sliding tube within the mounting frame, the motor drives a winding rod to rotate upon startup. During rotation, the winding rod winds up the connecting wire. A guide plate at the bottom of the sliding tube positions the connecting wire. Simultaneously, the winding rod synchronously drives the lead screw to rotate slowly, causing the sliding tube and guide plate to move synchronously. This movement pushes the connecting wire along the surface of the winding rod, ensuring that long-distance connecting wires are evenly wound onto the winding rod. This facilitates uniform winding of the connecting wires and prevents the mounting frame from being unable to accommodate long-distance connecting wires. After winding, the insect-attracting box is embedded in the receiving hole, and the magnetic plate at the top of the insect-attracting box is attracted and fixed to the magnetic metal plate, preventing it from falling downwards due to the weight of the insect-attracting box after the motor is turned off.

Detailed Implementation

[0026] 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.

[0027] This specific implementation method is a forestry pest and disease monitoring drone, and its structural diagram is shown below. Figure 1 and Figure 2 As shown, the forestry pest and disease monitoring drone includes a drone body 1 and a mounting frame 3 fixed to the bottom of the drone body 1. A winding rod 12 is rotatably mounted in the mounting frame 3, and a lead screw 15 is installed on the inner wall of the mounting frame 3. A connecting line 6 is fixedly wound on the winding rod 12, and an insect-attracting box 2 is fixed to the bottom of the connecting line 6. An adjustable mechanism for moving the connecting line 6 is installed on the lead screw 15, and the lead screw 15 rotates synchronously with the winding rod 12 through a meshing mechanism. The winding rod 12 in the mounting frame 3, through the connecting line 6, positions the insect-attracting box 2 below the drone body 1, thereby keeping the insect-attracting box 2 away from the drone. This greatly reduces the impact of wind on the flight of insects and improves the sampling effect of the insect-attracting box 2 on insect samples.

[0028] The mounting frame 3 has a receiving hole 4 at its bottom end, and both ends of the mounting frame 3 have inlet slots 5 that communicate with the receiving hole 4. Magnetic metal plates 8 are fixed to both sides of the inner wall of the receiving hole 4. The outer wall of the insect-attracting box 2 has multiple through slots 7, and both sides of the top surface of the insect-attracting box 2 have magnetic plates 19 that are attracted and fixed to the magnetic metal plates 8. After winding, the insect-attracting box 2 is embedded in the receiving hole 4, and the magnetic plates 19 at the top of the insect-attracting box 2 are attracted and fixed to the magnetic metal plates 8, preventing the motor 9 from falling downwards due to the gravity of the insect-attracting box 2 after closing. The motor 9 is fixedly installed on the outer wall of the mounting frame 3. The drive shaft of the motor 9 is fixedly connected to the winding rod 12. The meshing mechanism includes a first gear 10 fixedly sleeved on the winding rod 12 and a second gear 18 fixedly sleeved on the lead screw 15. The first gear 10 and the second gear 18 are meshed and connected. Both ends of 2 are fixedly sleeved with baffles 14. The moving mechanism includes a sliding tube 16 and a guide plate 17 with an L-shaped structure fixed at the bottom of the sliding tube 16. The sliding tube 16 is threaded onto the lead screw 15. The top wall of the mounting frame 3 is provided with a sliding groove 13. The top of the sliding tube 16 is fixed with a sliding rod 11 that fits into the sliding groove 13. After the motor 9 is started, it drives the winding rod 12 to rotate. During the rotation, the winding rod 12 winds up the connecting line 6. The guide plate 17 at the bottom of the sliding tube 16 positions the connecting line 6. At the same time, the winding rod 12 synchronously drives the lead screw 15 to rotate slowly with the first gear 10 and the second gear 18. During the rotation, the sliding tube 16 and the guide plate 17 move synchronously. During the movement, the connecting line 6 is pushed to move along the surface of the winding rod 12, so that the long connecting line 6 is evenly wound on the winding rod 12.

[0029] Working principle: When using the device of this technical solution, the motor 9 is started to rotate forward. The winding rod 12 in the mounting frame 3, through the connecting line 6, positions the insect trap 2 below the drone body 1, thereby keeping the insect trap 2 away from the drone and greatly reducing the impact of the drone's wind on the insects' flight. After the motor 9 starts to rotate in reverse, it drives the winding rod 12 to rotate. During the rotation, the winding rod 12 winds up the connecting line 6. The guide plate 17 at the bottom of the sliding tube 16 positions the connecting line 6. At the same time, the winding rod 12 synchronously drives the first gear 10 and the second gear 18 to drive the silk. The lever 15 rotates slowly, and during the rotation, the sliding tube 16 and the guide plate 17 move synchronously. During the movement, the connecting wire 6 is pushed to move along the surface of the winding rod 12, so that the long connecting wire 6 is evenly wound on the winding rod 12 and the connecting wire 6 is evenly wound up, avoiding the situation where the mounting frame 3 cannot accommodate the long connecting wire 6. After winding, the insect trap 2 is embedded in the receiving hole 4, and the magnetic plate 19 at the top of the insect trap 2 is attracted and fixed to the magnetic metal plate 8, preventing the motor 9 from falling down due to the gravity of the insect trap 2 after it is turned off.

[0030] All technical features in this embodiment can be freely combined according to actual needs.
