Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an inspection unmanned aerial vehicle for the treatment of pine wood nematodes. Background Art

[0002] Pine wilt disease is a disease that causes serious harm to pine trees. In order to prevent and control pests and diseases, it is necessary to spray pesticides in the forest area. With the continuous advancement of science and technology, drones equipped with multispectral cameras can monitor the spectral and spatial characteristics of diseased pine trees. Using infrared spectral imaging combined with deep learning algorithms, dead pine trees can be monitored efficiently and accurately. This method has the advantages of fast recognition speed, high accuracy, and process automation, providing reliable technical support for pine wilt disease monitoring. At the same time, drones can be used to spray pesticides over large areas to prevent and control pine wilt disease. This technology is called drone pesticide control, which is achieved by equipping patrol drones with pesticide spraying systems.

[0003] When traditional inspection drones are spraying pesticides, their spraying range is often limited by the fixed spraying structure and fixed nozzle layout. This meets the basic spraying needs to a certain extent, but in densely planted forest areas, more intensive spraying is required to ensure pesticide coverage. In sparse forest areas, too wide a spraying range leads to pesticide waste and environmental pollution. During the operation, once the drone takes off and starts spraying, its spraying range and pattern are often fixed and cannot be flexibly adjusted according to real-time changes in forest conditions, which has great limitations. Summary of the invention

The two groups of connecting plates 66 are respectively connected to water pipe 2 58 and water pipe 3 511, thereby expanding the spraying range and improving the efficiency of spraying medicine over a large area.

[0027] Specifically, first, after the medicine solution is input into the medicine box 51 through the input pipe 52, the drone is driven to take off, and the remote monitoring function is realized through the camera 4 arranged at the bottom of the drone body 1. At the same time, the medicine box 51 is supported and fixed by the fixing plate 3 fixedly installed by the legs 2. When spraying medicine in a large area of ​​forest area with high density, it is necessary to drive the expansion structure 6 to lengthen the length of the water pipe and expand the spraying range. The bidirectional motor 61 at the bottom of the driving fixing plate 3 is driven. The bidirectional motor 61 drives the screw rods 62 at both ends to rotate respectively. The screw rods 62 are threadedly connected with the corresponding sleeves 63, and the sleeves 63 drive the ring 64 arranged near one end of the bidirectional motor 61 to slide with the slide rod 65. The slide rod 65 is connected to the bidirectional motor 61. The outer shell is fixed, so that the two sets of sleeves 63 respectively drive the water pipe 2 58 and the water pipe 3 511 fixed on one side by the connecting plate 66 to move in the opposite direction to the outer end, and further the water pipe 2 58 and the water pipe 3 511 respectively slide in the slide groove 8 opened on the bottom surface of the fixing plate 3 through the slider 9 with a T-shape at the top, and then the three sets of pump bodies 53 inside the medicine box 51 are started at the same time, and the three sets of pump bodies 53 output the medicine inside the medicine box 51 to the inside of the connecting pipe 54, the hose 1 57 and the hose 2 510 respectively. Since the connecting pipe 54, the hose 1 57 and the hose 2 510 all pass through the bottom surface of the medicine box 51 and the three sets of pipe grooves corresponding to the surface of the fixing plate 3, they are respectively connected with the water pipe 1 55, the water pipe 2 58 and the water pipe 3 511, so that the connecting pipe 54, the hose 1 57 The medicine is transported to the inside of water pipe one 55, water pipe two 58 and water pipe three 511 by hose two 510, and a plurality of nozzles one 56, nozzle two 59 and nozzle three 512 are arranged at equal intervals at the bottom ends of water pipe one 55, water pipe two 58 and water pipe three 511, respectively. The medicine spraying work is carried out on a large area of ​​forest area through nozzles one 56, nozzle two 59 and nozzle three 512, so that the length of the water pipe two 58 and water pipe three 511 is extended to the outside, thereby expanding the spraying range and improving the efficiency of large-area medicine spraying. When it is necessary to spray medicine on a small area of ​​forest area, the water pipe two 58 and water pipe three 511 can be reversely retracted by reversely driving the bidirectional motor 61, and only the pump body 53 at one end of the connecting pipe 54 is started, and the other two groups of pumps are turned off. The body 53 does not need to be started, and the amount of water pipe 55 and the amount of spraying from the nozzle 56 can be adjusted by adjusting the structure 7. The motor 74 fixed on one side of the driving shell 72 through the extension plate 73 drives the motor 74. The shell 72 is connected and fixed to the bottom end of the fixed plate 3 through four groups of support blocks 71. The motor 74 drives the gear 75 at the output end to mesh with the rack 1 76 and the rack 2 79 respectively. The rack 1 76 and the rack 2 79 are respectively slidably connected to the shell 72. The rack 1 76 and the rack 2 79 are respectively moved in the grooves opened at both ends of the shell 72. The rack 1 76 and the rack 2 79 respectively drive the push rod 1 77 and the push rod 2 710 at each end to move toward the middle. The push rod 1 77 and the push rod 2 710 are respectively slidably connected to the water pipe 55.Push rod 1 77 and push rod 2 710 respectively drive piston 1 78 and piston 2 711, each of which has one end extending into the interior of water pipe 1 55 and connected thereto, to move toward the middle of water pipe 1 55, so that piston 1 78 and piston 2 711 reduce the volume inside water pipe 1 55, and piston 1 78 and piston 2 711 gather water in the middle of water pipe 1 55, reducing the number of spray nozzles 1 56 that can be sprayed, thereby making the water inside water pipe 1 55 only pass through several groups of spray nozzles 1 56 in the middle for drug spraying, which is convenient for adjustment and can be sprayed according to the actual situation of the forest area, avoiding the waste of water resources, while improving the spraying efficiency, and improving the versatility and market competitiveness of the equipment.
