Description

Technical Field

[0001] This invention relates to the field of forestry management technology, specifically to a drone used for monitoring forest pests and diseases. Background Technology

[0002] In recent years, with the continuous development of science and technology, drone technology has been widely used in various industries. Among them, forestry pest and disease monitoring has become one of the application areas of drones. By using drones equipped with high-resolution cameras and other sensors, data can be collected from trees, grasslands and other areas in forests. This data can then be used for pest and disease monitoring. Drones can take advantage of their small size and high degree of freedom to fly at low altitudes and collect pest and disease related data through high-definition cameras and other equipment, achieving accurate location and identification of pest and disease occurrences. Compared with traditional manual inspections, this greatly improves monitoring efficiency.

[0003] However, due to the large area of ​​the forest, trees with pests and diseases located by drones in the air need to be treated manually. The personnel working on the ground make it difficult to accurately identify the trees located by the drones. At the same time, the ground view is blocked, making it difficult to visually distinguish the trees affected by pests and diseases. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a drone for monitoring forest pests and diseases, solving the problem that it is difficult for management personnel to accurately locate trees affected by pests and diseases after they are discovered.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a drone for monitoring forest pests and diseases, comprising a main body, a pair of connecting rods fixedly connected to both sides of the main body, a first motor fixedly connected to the end of each pair of connecting rods away from the main body, a propeller fixedly connected to the output end of the first motor, a plurality of fixed plates fixedly connected through the upper surface of the main body, bolts fixedly connected through the ends of the fixed plates away from the main body, a launching mechanism fixedly connected to the bolts, landing gear fixedly connected to both sides of the lower surface of the main body, a buffer plate fixedly connected to the end of the landing gear away from the main body, a camera assembly fixedly connected to the lower surface of the main body, and a positioning projectile disposed within the launching mechanism.

[0006] The above technical solution allows the positioning projectile to be launched onto trees affected by pests and diseases, enabling management personnel to quickly and accurately locate the affected trees, facilitating pest and disease control and greatly improving management efficiency.

[0007] Preferably, the landing gear is made of stainless steel and is fixedly connected to the main body by welding. Rubber is fixedly connected to the outside of the buffer plate. The shell of the main body is made of stainless steel and the connecting rod is made of aluminum alloy.

[0008] The above technical solutions improve the overall robustness, while the rubber provides some cushioning to prevent damage to the drone during landing due to excessive descent.

[0009] Preferably, the launching mechanism includes a housing, which is fixedly connected to the main body. An infrared sight is fixedly connected to one end of the housing, a power box is fixedly connected to the side of the housing away from the infrared sight, a battery is fixedly connected to the side of the housing away from the power box, and a magazine is fixedly connected to the upper end of the housing.

[0010] The above technical solution can improve shooting accuracy by using an infrared aiming device, ensuring that trees affected by pests and diseases are hit and achieving precise positioning.

[0011] Preferably, a pair of first grooves are provided in the end of the magazine away from the outer shell, and an end cap is slidably connected to the end of the magazine away from the outer shell. Both ends of the end cap are fixedly connected to slide rails, and the slide rails slide in cooperation with the first grooves.

[0012] The above technical solution allows the positioning bullet to be automatically loaded into the barrel by gravity, and multiple positioning bullets can be loaded into the magazine, enabling the drone to identify multiple targets.

[0013] Preferably, a second motor is fixedly connected inside the power box, a cavity is opened inside the outer shell, a rotating shaft is rotatably connected through the end of the cavity away from the infrared sight, the output end of the second motor is fixedly connected to the rotating shaft, a rotating wheel is fixedly connected to the rotating shaft, a first connecting rod is rotatably connected to the rotating shaft, a cylinder is fixedly connected to the side of the rotating wheel near the first connecting rod, and a gun barrel is opened at the end of the outer shell near the infrared sight.

[0014] The above technical solution allows the motor to drive the turntable to rotate, thereby repeatedly actuating the first link, which in turn drives the firing lever to reciprocate through the second link, enabling continuous firing.

[0015] Preferably, the end of the first connecting rod away from the rotating shaft is rotatably connected to a second connecting rod, the end of the second connecting rod away from the first connecting rod is fixedly connected to a fixing rod, and the end of the second connecting rod away from the first connecting rod is rotatably connected to a firing lever. The firing lever and the barrel slide against each other. A pair of second grooves are provided on the side of the cavity away from the rotating wheel, and a slide is provided on the side of the barrel near the magazine. A tension spring is fixedly connected in each of the second grooves, and the end of the tension spring away from the second groove is fixedly connected to the fixing rod. The end of the firing lever away from the second connecting rod is rounded.

[0016] The above technical solution allows the tension spring to drive the firing lever to launch the positioning bullet, and when the firing lever retracts, the positioning bullet can slide into the barrel through the slide rail, allowing it to be automatically loaded.

[0017] Preferably, the positioning projectile includes a projectile body that slides with a magazine. One end of the projectile body is fixedly connected to an arrow, and several barbs are fixedly connected to the arrow. Several third grooves are provided at the end of the projectile body away from the arrow. A tail fin is rotatably connected to the third groove. Torsion springs are fixedly connected to both sides of the tail fin. A stop block is fixedly connected to the third groove near the torsion spring.

[0018] The above technical solutions can prevent the positioning missile from falling off the tree, and at the same time, the tail fins can be used to increase stability and improve the accuracy of the hit.

[0019] Preferably, the camera assembly includes a mounting base, which is fixedly connected to the main body. A gimbal is rotatably connected inside the mounting base, an optical lens is fixedly connected to the gimbal, and a laser rangefinder is fixedly connected to the gimbal.

[0020] The above technical solutions enable drones to patrol forests from high altitudes, locate pests and diseases through optical lenses, calculate the distance between the drone and trees using laser rangefinders to prevent drone collisions, provide a suitable launch distance, and make the firing of homing missiles more accurate by combining optical lenses with infrared aiming devices.

[0021] Working principle: The main body 1 drives the propeller 4 to rotate via the first motor 3 on the connecting rod 2, thus achieving flight. Observation is conducted through the optical lens 93 of the 9-liter camera assembly. When encountering trees affected by pests or diseases, the distance between the drone and the tree is first measured using a laser rangefinder 94. Once a suitable distance is reached, the infrared sight 53 is activated, and observation is conducted through the optical lens 93 to ensure the infrared sight 53 is aligned with the tree. Then, the second motor 511 is activated, driving the rotating shaft 512 to rotate. The rotating shaft 512 drives the rotating wheel 513 to rotate, which in turn drives the cylinder 514 to rotate, thus pressing down the first connecting rod 515. At this time, the first connecting rod 515 drives the second connecting rod 516 to move, and the second connecting rod 516 drives the impact... When the firing lever 521 retracts, the positioning cartridge 8, lacking the obstruction of the firing lever 521, enters the barrel 52 from the magazine 56 via the slide 520. Simultaneously, the second connecting rod 516 drives the fixing rod 517 to retract, pulling the tension spring 519. When the first connecting rod 515 rotates 180 degrees, the cylinder 514, located below the first connecting rod 515, cannot prevent the first connecting rod 515 from rotating clockwise. Thus, the tension spring 519 pulls the fixing rod 517 to move, causing the firing lever 521 to push the positioning cartridge 8 out along the barrel 52. After the positioning cartridge 8 exits the barrel, the lack of obstruction from the barrel 52 causes the torsion spring 85 to drive the tail fin 86 to pop out, which is fixed by the stop block 87. Then, the arrow 82 pierces the tree, and the barb 83 prevents it from falling off.

[0022] (III) Beneficial Effects This invention provides a drone for monitoring forest pests and diseases. It has the following beneficial effects: 1. This invention improves the efficiency and accuracy of pest and disease monitoring by installing a camera assembly under the main body of the drone and using multiple cameras for joint identification and monitoring. Furthermore, by installing a launching mechanism on the main body, a positioning projectile can be launched to hit the trees affected by pests and diseases. Through the positioning module inside the projectile, the management personnel can quickly and accurately identify the affected trees, greatly improving the management efficiency.

[0023] 2. This invention allows the launching mechanism to carry multiple positioning missiles by installing a magazine, facilitating the marking of multiple trees. Furthermore, by installing an infrared sight in front of the launching mechanism and setting a pop-out tail fin at the tail of the positioning missile, the missile's flight becomes more stable and the aiming more accurate. The barb prevents the positioning missile from falling off after impact, avoiding positioning failure. At the same time, the rangefinder on the camera assembly allows the drone to fly to a suitable distance before launching, preventing the positioning missile from missing its target.
