Description

Technical Field

[0001] The invention relates to the technical field of pest monitoring, and in particular to an unmanned aerial vehicle monitoring device for pine wood nematode pests. Background Art

[0002] Pine wilt disease, also known as pine wilt disease, is a systemic infectious disease that can cause the pine vascular system to lose its water-conducting function, causing the tree to wilt and die quickly. Pine nematode pests are controlled through comprehensive management measures, including monitoring, timely removal and destruction of diseased trees, chemical control, biological control, and the use of disease-resistant varieties.

[0003] Pine trees are mainly planted in the Greater Khingan Range and Lesser Khingan Range in the northeast, and the plateau areas in the southwest. Therefore, the diagnosis of pine wilt disease is mainly based on drone remote sensing images. By obtaining drone remote sensing images of the epidemic area, the images are spliced ​​to generate images with geographic location coordinates of the covered area. Then, image segmentation or target positioning network models are used to identify the discolored wood affected by pine wilt disease in the spliced ​​images. At the same time, the specific location coordinates of the discolored wood are obtained based on the geographic location of the spliced ​​image with geographic location coordinates.

[0004] The drone monitoring device uses a camera to shoot during the monitoring process. Pine leaves are long and thin needles, usually growing in clusters with a few to dozens of leaves in each cluster. The pine leaves grow lushly. When the weather is relatively calm, the pine leaves do not move. The pine leaves in the front may block the growth of the pine leaves in the back, and the captured image only shows the outermost pine leaves. The position of the drone monitoring device needs to be constantly adjusted to capture the pine leaves in the back, which greatly increases the monitoring operation time. Summary of the invention

[0005] The purpose of the present invention is to provide an unmanned aerial vehicle monitoring device for pine wood nematode pests, so as to solve the problem raised by the above background technology that the unmanned aerial vehicle monitoring devices currently on the market need to constantly adjust their positions in order to photograph the inner pine leaves.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a drone monitoring device for pine wood nematode pests, comprising a drone body and a camera, the camera being located below the drone body, a conversion frame being installed at the rear end of the camera, and a booster nozzle being provided on the conversion frame to blow on the leaves of the surrounding pine forest for monitoring.

[0007] Preferably, a motor is installed at the bottom end of the drone body, a mounting rod is installed at the output end of the motor, an air pump is installed at the bottom end of the mounting rod, a connecting pipe is installed at the top of the air pump, and a conversion frame is installed at the other end of the connecting pipe.

[0008] Preferably, a boost nozzle is installed at an equal angle at one end of the conversion frame close to the camera, the boost nozzle is located outside the camera, and a plurality of air inlets are provided at one end of the suction pump away from the camera.

[0009] Preferably, a fixing plate is installed at the bottom end of the UAV body, and a fixing block is installed on the inner wall of the fixing plate.

[0010] Preferably, a first sponge and a second sponge are installed on the inner side of the fixing plate, and the first sponge is located between the second sponge and the fixing block.

[0011] Preferably, a mounting plate is slidably provided at the bottom of the UAV body, a water storage pipe is installed in the middle of the mounting rod, and a pressing head and a nozzle are installed on the water storage pipe.

[0012] Preferably, a connecting rod is installed on the inner wall of the fixing plate, and a gear ring is installed on the other end of the connecting rod.

[0013] Preferably, a fixing rod is rotatably connected in the middle of the conversion frame, a gear is installed at one end of the fixing rod away from the boost nozzle, and a baffle is installed at the other end of the fixing rod.

[0014] Preferably, the baffle is a paddling paddle structure, the baffle corresponds to the boost nozzle one-to-one, the gear is meshed with the tooth block on the gear ring, and the mounting rod is inserted into the interior of the gear ring.

[0015] Preferably, the pressing head and the nozzle both protrude from the outside of the mounting plate, and the angle formed by the mounting plate is less than 360 degrees.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention is provided with a camera, and the camera is used to photograph trees in a forest area during the flight of a drone main body. A main control unit and a positioning unit are both arranged in the drone main body, and the main control unit is connected to the camera and a terminal control device. The main control unit transmits image data photographed by the camera back to the terminal control device to determine whether the trees in the forest area are infected with diseases and insect pests. When it is determined that the trees are infected with diseases and insect pests, the positioning unit sends the longitude and latitude of the photographing position to the terminal control device. The specific position of the pine wood nematode pest can be known through the terminal control device, thereby realizing the monitoring function. When the trees infected with diseases and insect pests are prevented and treated in the later stage, the trees infected with diseases and insect pests can be found conveniently and quickly. When the photographed image is blurred, the camera will rotate and be wiped by a wet first sponge and a dry second sponge, so that the stains on the camera will be wiped clean, thereby improving the clarity of the image photographed by the camera. The camera can be processed when the drone body is in the air, and there is no need to operate after the drone body is lowered, thereby reducing time consumption and improving work efficiency.

[0018] 2. The present invention is provided with an air suction pump. When the air suction pump is operated, the gas enters the conversion frame through the air inlet, and then the gas is pressurized by the boost nozzle to generate a strong wind. The wind blows the pine leaves to turn them over, thereby preventing the pine wood nematode pests on the back of the pine leaves or inside the trunk from being captured by the camera. The turning leaves make the image captured by the camera more comprehensive, and there is no need to constantly adjust the position of the drone body, so that the image can more comprehensively display the situation of the pine leaves.

[0019] 3. The present invention is provided with a gear ring and a gear. When the camera rotates backward to prepare for wiping, the camera does not need to shoot the pine forest around it during the wiping process, so there is no need to blow on the leaves. The blowing of the leaves may cause surrounding dust to be raised. When the camera rotates, the gear ring rotates the gear, which then makes the gear rotate while revolving. The rotation of the gear makes the baffle rotate to the end of the boost nozzle to block the boost nozzle. The gas will not be ejected from the boost nozzle position, thereby reducing the flow rate of the surrounding air, thereby preventing dust from being re-adsorbed onto the camera and keeping the camera clean.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0034] A drone monitoring device for pine wood nematode pests includes a drone body 1 and a camera 4, wherein the camera 4 is located below the drone body 1, a conversion frame 15 is installed at the rear end of the camera 4, a booster nozzle 16 is provided on the conversion frame 15, and blows on the leaves of the surrounding pine forest for monitoring, an air pump 3 is installed at the bottom end of the mounting rod 20, a connecting pipe 18 is installed on the top of the air pump 3, and the conversion frame 15 is installed on the other end of the connecting pipe 18, the booster nozzle 16 is installed at an equal angle at one end of the conversion frame 15 close to the camera 4, the booster nozzle 16 is located outside the camera 4, and a plurality of air inlets 22 are provided at one end of the air pump 3 away from the camera 4.

[0035] During the shooting process, the air pump 3 runs to generate suction, which draws wind into the conversion frame 15 from the air inlet 22. The gas is pressurized by the booster nozzle 16, and the pressurized gas is ejected through the booster nozzle 16, so that the pressure of the ejected gas is relatively high. The gas blows on the surrounding pine leaves, and the leaves sway and turn over after being blown. The camera 4 can shoot the back of the leaves or the leaves far away from the camera 4, making the shooting of the camera 4 more comprehensive.

[0036] A motor 9 is installed at the bottom end of the drone body 1, and a mounting rod 20 is installed at the output end of the motor 9. A first sponge 10 and a second sponge 11 are installed on the inner side of the fixing plate 2, and the first sponge 10 is located between the second sponge 11 and the fixing block 8.

[0037] When the captured image is blurry, the handle remotely controls the motor 9 to start, and the operation of the motor 9 causes the mounting rod 20 to rotate. The rotation of the mounting rod 20 drives the suction pump 3 to rotate synchronously. Since the suction pump 3, the conversion frame 15, the connecting pipe 18 and the camera 4 are fixedly installed, the camera 4 will rotate synchronously with the mounting rod 20. When the camera 4 rotates to contact with the first sponge 10, the wet first sponge 10 wipes the camera 4 to wipe off the dust on the surface of the camera 4. When the camera 4 rotates to contact with the second sponge 11, the surface of the camera 4 wiped by the first sponge 10 will have moisture. Then the dry second sponge 11 wipes the camera 4 again, and the moisture on the surface of the camera 4 passing through the second sponge 11 will be wiped dry, so that the camera 4 remains dry, which can reduce the amount of dust on the shaking pine leaves sticking to the surface of the camera 4.

[0038] The main control unit and the positioning unit are both arranged in the main body of the UAV. The main control unit is connected to the camera 4 and the terminal control device. The main control unit transmits the image data taken by the camera 4 back to the terminal control device to determine whether the trees in the forest area are suffering from diseases and insect pests. When it is determined that the trees are suffering from diseases and insect pests, the positioning unit sends the longitude and latitude of the shooting position to the terminal control device. The specific location of the pine wood nematode pest can be known through the terminal control device, realizing the monitoring function. When the trees suffering from diseases and insect pests are prevented and treated in the later stage, the trees suffering from diseases and insect pests can be found conveniently and quickly.

[0039] A fixing plate 2 is installed at the bottom end of the drone body 1, and a fixing block 8 is installed on the inner wall of the fixing plate 2. A mounting plate 5 is slidably provided at the bottom of the drone body 1. A water storage pipe 21 is installed in the middle of the mounting rod 20, and a pressing head 6 and a nozzle 7 are installed on the water storage pipe 21. The pressing head 6 and the nozzle 7 both protrude from the outside of the mounting plate 5, and the angle formed by the mounting plate 5 is less than 360 degrees.

[0040] When the camera 4 is rotating, the mounting rod 20 rotates, driving the water storage pipe 21, the nozzle 7 and the pressing head 6 to rotate synchronously. When the pressing head 6 rotates to contact with the fixed block 8, the nozzle 7 just rotates to the position of the first sponge 10. The fixed block 8 squeezes the pressing head 6, and the liquid inside the water storage pipe 21 is sprayed onto the first sponge 10 through the nozzle 7, wetting the first sponge 10 and keeping the first sponge 10 in a wet state.

[0041] A connecting rod 14 is installed on the inner wall of the fixing plate 2, and a gear ring 13 is installed on the other end of the connecting rod 14. A fixing rod 19 is rotatably connected in the middle of the conversion frame 15. A gear 12 is installed on the end of the fixing rod 19 away from the boost nozzle 16, and a baffle 17 is installed on the other end of the fixing rod 19. The baffle 17 is a paddling paddle structure, and the baffle 17 corresponds to the boost nozzle 16 one by one. The gear 12 is meshed with the tooth block on the gear ring 13, and the mounting rod 20 is inserted into the interior of the gear ring 13.

[0042] The rotation of the conversion frame 15 drives the fixed rod 19 and the gear 12 to rotate synchronously. When the gear 12 rotates to mesh with the tooth block on the gear ring 13, since the position of the gear ring 13 is fixed, the gear ring 13 causes the gear 12 to rotate. The rotation of the gear 12 drives the fixed rod 19 and the baffle 17 to rotate synchronously. The baffle 17 rotates and gradually approaches the boost nozzle 16, blocks the boost nozzle 16, and reduces the flow of surrounding air. Then, when the gear 12 continues to rotate, it separates from the tooth block on the gear ring 13, and the gear 12 will not rotate on its own. At this time, the position of the baffle 17 remains unchanged. When the camera 4 is about to rotate out, the gear ring 13 meshes with the tooth block on the gear 12 again, and the baffle 17 rotates again. The baffle 17 gradually moves away from the boost nozzle 16. After the camera 4 rotates one circle, the baffle 17 is just intertwined with the boost nozzle 16, and the baffle 17 is completely separated from the boost nozzle 16, and the baffle 17 will not affect the normal blowing of the boost nozzle 16.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
