Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) airport technology, specifically a fixed automated UAV airport. Background Technology

[0002] Unmanned aerial vehicle (UAV) airports, also known as automated UAV airports, are dedicated facilities that provide services such as take-off, landing, maintenance, charging, and storage for UAVs. They are highly automated and intelligent, enabling automated management and scheduling of UAVs, improving operational efficiency and service quality. UAVs can take off and land at UAV airports without human intervention. UAV airports can provide charging services to ensure continuous operation of UAVs and can store them safely and reliably. UAV airports have applications in many fields and are an important part of the UAV industry. They will provide strong support for the future development of intelligence and automation.

[0003] In the agricultural sector, spraying has gradually been replaced by drone operations. By equipping drones with pesticide spraying equipment, drones can accurately apply pesticides, improving spraying efficiency and reducing health hazards to operators. However, in actual use, due to the often large area of ​​farmland, drones cannot carry enough pesticides at once, usually requiring repeated manual additions. During repeated additions, pesticides may have adverse effects on the health of operators. Furthermore, solid residues from pesticide production, paper scraps and fibers from pesticide bottles, and precipitates formed by reactions between pesticides and other chemicals can all clog nozzles, leading to reduced spraying effectiveness or even failure to spray. Therefore, we propose a fixed automated drone farm. Summary of the Invention

A drive component 6 is fixedly installed on the housing 1. A sleeve 7 that cooperates with the screw 8 is rotatably installed inside the drive component 6. When it is necessary to open the unmanned airport, the drive component 6 controls the internal sleeve 7 to rotate. Through the cooperation between the sleeve 7 and the screw 8, the cover plate 3 drives the rollers 5 to move along the slide rail 4, so that the unmanned airport is opened. When closing, the drive component 6 controls the sleeve 7 to reverse, so that the cover plate 3 drives the rollers 5 to reset along the slide rail 4, so that the unmanned airport is closed.

[0034] A lifting platform 34 is fixedly installed inside the housing 1. A landing platform 11 for parking drones is fixedly installed on the upper end of the lifting platform 34. A first drive device 18 and a second drive device 28 are fixedly installed on the landing platform 11. A first rotating rod 19 is fixedly installed at the output end of the first drive device 18, and a second rotating rod 29 is fixedly installed at the output end of the second drive device 28. First pulleys 20 are fixedly installed at both ends of the first rotating rod 19 and both ends of the second rotating rod 29. Several second pulleys 21 are rotatably mounted on the landing platform 11, and each second pulley 21 corresponds to one of the first pulleys 20. A first transmission belt 22 is connected to each first pulley 20 on the first rotating rod 19 and the corresponding second pulley 21. Each pulley 20 is connected to a corresponding second pulley 21 by a second transmission belt 30. Each first transmission belt 22 is fixedly mounted with a first connecting member 24 and a second connecting member 25. A first transverse push rod 14 is fixedly connected between two first connecting members 24, and a second transverse push rod 15 is fixedly connected between two second connecting members 25. Each second transmission belt 30 is fixedly mounted with a third connecting member 26 and a fourth connecting member 27. A first vertical push rod 16 is fixedly connected between two third connecting members 26, and a second vertical push rod 17 is fixedly connected between two fourth connecting members 27. Two first guide rods 23 are fixedly mounted on the stopping platform 11. Each first connecting member 24 and each second connecting member 25 are slidably mounted on their corresponding guide rods. On the first guide rod 23, two second guide rods 31 are also fixedly installed on the parking platform 11. Each third connector 26 and fourth connector 27 is slidably installed on the corresponding second guide rod 31. When the lifting platform 34 drives the parking platform 11 to rise, the first drive device 18 and the second drive device 28 respectively drive the first rotating rod 19 and the second rotating rod 29 to rotate in the forward direction. The first rotating rod 19 drives the first transmission belts 22 on both sides to move through the corresponding first pulley 20 and second pulley 21. Both first pulleys 20 drive the first connector 24 and the second connector 25 on them to move in the opposite direction along the first guide rod 23, so that the first transverse push rod 14 and the second transverse push rod 15 move in the opposite direction along the first guide rod 23. Simultaneously, the second rotating rod 29 drives the second transmission belts 30 on both sides to move via the corresponding first pulley 20 and second pulley 21. Both second transmission belts 30 drive the third connecting member 26 and the fourth connecting member 27 on them to move in opposite directions along the second guide rod 31, causing the first vertical push rod 16 and the second vertical push rod 17 to move in opposite directions along the second guide rod 31. When the lifting platform 34 drives the stopping platform 11 to descend, the first drive device 18 and the second drive device 28 respectively drive the first rotating rod 19 and the second rotating rod 29 to rotate in opposite directions, and the first transmission belt 22 and the second transmission belt 30 also move in opposite directions, causing the first transverse push rod 14 and the second transverse push rod 15 to return to their original positions relative to each other along the first guide rod 23.The first vertical push rod 16 and the second vertical push rod 17 also move relative to each other along the second guide rod 31 to reset, allowing the drone to park in a fixed position. Several sensors 33 for detecting the drone's weight are fixedly installed on the parking platform 11. The positions of the sensors 33 correspond one-to-one with the positions of the drone's support feet. Each sensor 33 is made of elastic material to cushion the drone's landing. When the drone is parked in the fixed position, the sensors 33 can sense the weight of the drone and the pesticide inside. A charging device 32 for charging the drone is also fixedly installed on the parking platform 11. After parking, the charging device 32 charges the drone. After charging is complete, the charging device 32 automatically resets.

[0035] A pesticide storage tank 12 is fixedly installed inside the housing 1. A feed pipe 13 is fixedly installed on the tank 12, and a flexible feeding pipe 37 is fixedly installed at the bottom of the tank 12. A feeding valve 38 is fixedly installed on the feeding pipe 37, and a feeding port 36 is fixedly installed at one end of the feeding pipe 37. A connecting push rod 35 is fixedly installed on the feeding port 36. The connecting push rod 35 is fixedly installed on the parking platform 11. After the drone is parked, the connecting push rod 35 drives the feeding port 36 to connect with the drone's hopper and controls the feeding valve 38 to add the pesticide from the tank 12 into the drone through the feeding pipe 37. When the sensor 33 senses that the weight of the drone and the pesticide inside it reaches the mark, it controls the feeding valve 38 to stop adding pesticide and controls the connecting push rod 38 to stop adding pesticide. 5. The feeding port 36 is reset, disconnecting from the drone's feed bin. A cylinder 41 is fixedly installed on the loading barrel 12. A fixing part 42 is fixedly installed on the output end of the cylinder 41. A filter cloth 43 for filtering pesticides is fixedly installed on the fixing part 42. The filter cloth 43 is tightly attached to the inner wall of the loading barrel 12 and is in a taut state. After a period of time, impurities and sediments in the pesticides in the loading barrel 12 are attached to the filter cloth 43. Two first scrapers 44 are rotatably installed on the cylinder 41. The lower end of each first scraper 44 is tightly attached to the filter cloth 43. A guide block 45 is fixedly installed at one end of each first scraper 44. Two spiral grooves 46 are symmetrically arranged on the inner wall of the loading barrel 12 to limit the guide blocks 45. The cylinder 41 drives the fixing part 42. During recycling, the filter cloth 43 carries impurities and sediments upwards. Simultaneously, the cylinder 41 drives the two first scrapers 44 upwards. The spiral grooves 46 limit the guide blocks 45, causing the two first scrapers 44 to rotate around the centerline of the cylinder 41 during the upward movement, scraping away impurities and sediments from the filter cloth 43. A collection bin 40 is fixedly installed on the loading hopper 12, with one end of each spiral groove 46 located at the connection between the collection bin 40 and the loading hopper 12. When the cylinder 41 retracts, the guide blocks 45 on the two first scrapers 44 move to the ends of the corresponding spiral grooves 46. At this point, the two first scrapers 44 form a fan-shaped area on the filter cloth 43, and the impurities and sediments on the filter cloth 43 are concentrated in this fan-shaped area. Within the area, the bottom of the collection chamber 40 is sloping downwards. An impurity adsorption device 39 for collecting impurities within the collection chamber 40 is fixedly installed on the outer wall of the filling barrel 12. A sensor 47 for detecting the pesticide liquid level inside the barrel is fixedly installed on the inner wall of the filling barrel 12. When pesticide is added to the filling barrel 12, if the pesticide liquid level is about to reach the collection chamber 40, the operator is prompted to stop adding pesticide to prevent pesticide from entering the collection chamber 40. A rubber plate 48 is fixedly installed on the inner wall of the filling barrel 12. The rubber plate 48 is shaped like an upward-facing arc. During the upward movement of the cylinder 41, which drives the fixing part 42 and the filter cloth 43, the rubber plate 48 is pushed upwards and deformed. After passing the end of the rubber plate 48, the rubber plate 48 returns to its original position using its own elasticity.To prevent impurities and sediments on the filter cloth 43 from falling into the lower loading hopper 12, the inner wall of the loading hopper 12 is provided with a deformation groove 49 corresponding to the rubber plate 48. When the cylinder 41 drives the fixing member 42 and the filter cloth 43 to descend, it compresses the rubber plate 48 downward into the deformation groove 49, so that the rubber plate 48 does not obstruct the downward movement and reset of the fixing member 42 and the filter cloth 43. After passing the end of the rubber plate 48, the rubber plate 48 resets again using its own elasticity.

[0036] A device plate 50 is fixedly installed on the inner top wall of the loading hopper 12. A first magnetic block 51 is slidably installed vertically inside the device plate 50. A collar 65 is fixedly installed at the lower end of the first magnetic block 51. A second magnetic block 52, which is mutually repellent to the first magnetic block 51, is slidably installed horizontally inside the device plate 50. A first spring 53 is fixedly installed at one end of the second magnetic block 52 and one end of the first spring 53 is fixedly connected to the device plate 50. First balls 54 are provided on both sides of the second magnetic block 52. Guide grooves 55 for limiting the first balls 54 are provided on both sides of the inner wall of the device plate 50. During the upward movement of the first scraper 44 driven by the cylinder 41, after the first scraper 44 contacts the collar 65, it drives the collar 65 and the first magnetic block 51 to rise synchronously. When the cylinder 41 has finished rising, the first... Magnetic block 51 and second magnetic block 52 are on the same horizontal line. Due to magnetic repulsion between them, the second magnetic block 52 drives the first ball 54 to move along the guide groove 55, compressing the first spring 53. A telescopic column 56 is fixedly installed at the lower end of the second magnetic block 52, and a second scraper 60 is fixedly connected to the lower end of the telescopic column 56. A sliding plate 57 is slidably installed on the telescopic column 56. Several third springs 66 are fixedly installed at the lower end of the sliding plate 57, and the lower end of each third spring 66 is fixedly connected to the second scraper 60. Several second balls 58 are provided at the upper end of the sliding plate 57. Several grooves 59 for limiting the second balls 58 are provided at the bottom of the device plate 50, with each groove 59 corresponding to a second ball 58. Two second balls 58 are symmetrically arranged on one side of the second scraper 60. Three scrapers 61, each with several limiting blocks 63 fixedly installed. The second scraper 60 has several limiting grooves 64 for limiting the limiting blocks 63, with each groove corresponding to a limiting block 63. Several second springs 62 are fixedly connected between the two third scrapers 61. During the upward movement of the cylinder 41, which drives the fixing member 42 and the filter cloth 43, the filter cloth 43 contacts the lower ends of the second scraper 60 and the two third scrapers 61, causing them to move upward. This retracts the telescopic column 56 and moves the third spring 66 and the sliding plate 57 upward. When the second ball 58 is located in the corresponding groove 59, the sliding plate 57 stops moving, the third spring 66 is compressed, and the lower ends of the second scraper 60 and the third scraper 61 are tightly pressed together. As the filter cloth 43 rises, the two first scrapers 44 move in a circular motion. When they come into contact with the corresponding third scraper 61, they push the third scraper 61 inward along the limiting groove 64, compressing the second spring 62. The second scraper 60 and the third scraper 61 are initially located at the narrow end of the uncleaned fan-shaped area on the filter cloth 43. When the second magnetic block 52 moves, it drives the second scraper 60 and the third scraper 61 to move synchronously from the narrow end of the fan-shaped area to the other end. During the movement, the elastic force of the second spring 62 keeps one end of the two third scrapers 61 in close contact with the corresponding first scraper 44, scraping away the impurities and sediments accumulated in the fan-shaped area on the filter cloth 43 into the collection chamber 40.After scraping is complete, cylinder 41 repositions the fixing member 42 and filter cloth 43, causing them to descend and reset. The first scrapers 44 on both sides also move and reset along the spiral groove 46. The first magnetic block 51 and collar 65 reset under gravity. The first magnetic block 51 and second magnetic block 52 repel each other, and the first spring 53 elastically drives the second magnetic block 52 to reset. The second magnetic block 52 then drives the second scraper 60 and third scraper 61 to reset. The second spring 62's elastic force causes the two third scrapers 61 to move in opposite directions along the limiting groove 64 to reset. The second scraper 60 moves downward under gravity to reset, thus resetting the telescopic column 56 and sliding plate 57.

[0037] Specifically, when the drone airport needs to be opened, the drive unit 6 controls the internal sleeve 7 to rotate. Through the cooperation of the sleeve 7 and the screw 8, the cover plate 3 drives the roller 5 to move along the slide rail 4, thus opening the drone airport. When closing, the drive unit 6 controls the sleeve 7 to reverse, causing the cover plate 3 to drive the roller 5 to return to its original position along the slide rail 4, thus closing the drone airport. When the drone needs to take off or is about to land, the lifting platform 34 will drive the parking platform 11 to rise. The first drive device 18 and the second drive device 28 respectively drive the first rotating rod 19 and the second rotating rod 29 to rotate in the forward direction. The first rotating rod 19 is connected to the corresponding first pulley. The first pulley 20 and the second pulley 21 drive the first transmission belts 22 on both sides to move. Both first pulleys 20 drive the first connecting piece 24 and the second connecting piece 25 on them to move in the opposite direction along the first guide rod 23, causing the first transverse push rod 14 and the second transverse push rod 15 to move in the opposite direction along the first guide rod 23. Simultaneously, the second rotating rod 29 drives the second transmission belts 30 on both sides through the corresponding first pulley 20 and second pulley 21. Both second transmission belts 30 drive the third connecting piece 26 and the fourth connecting piece 27 on them to move in the opposite direction along the second guide rod 31, causing the first vertical... Push rod 16 and the second vertical push rod 17 move in opposite directions along the second guide rod 31. After the UAV has taken off or landed, the lifting platform 34 will drive the landing platform 11 to descend. The first drive device 18 and the second drive device 28 will drive the first rotating rod 19 and the second rotating rod 29 to rotate in opposite directions, and the first transmission belt 22 and the second transmission belt 30 will also move in opposite directions, causing the first horizontal push rod 14 and the second horizontal push rod 15 to return to their relative positions along the first guide rod 23. The first vertical push rod 16 and the second vertical push rod 17 will also return to their relative positions along the second guide rod 31. When the drone is parked in a fixed position, the sensor 33 can sense the weight of the drone and the pesticide inside it. The charging device 32 charges the drone. After the drone is parked, the connecting push rod 35 drives the feeding port 36 to connect with the drone's hopper and controls the feeding valve 38 to add the pesticide from the loading barrel 12 into the drone through the feeding pipe 37. When the sensor 33 senses that the weight of the drone and the pesticide inside it has reached the mark, it will control the feeding valve 38 to stop adding pesticide and control the connecting push rod 35 to reset the feeding port 36, disconnecting it from the drone's hopper.

[0038] The cylinder 41 operates periodically to filter the pesticides in the loading tank 12. When the cylinder 41 retracts the fixing part 42, the filter cloth 43 carries impurities and sediments upwards. Simultaneously, the cylinder 41 drives the two first scrapers 44 upwards. The guide blocks 45 are limited by the spiral grooves 46, causing the two first scrapers 44 to rotate around the centerline of the cylinder 41 during the upward movement, scraping away impurities and sediments on the filter cloth 43. A collection bin 40 is fixedly installed on the loading tank 12, with one end of each spiral groove 46 located at the connection between the collection bin 40 and the loading tank 12. When the cylinder 41 retracts, the guide blocks 45 on the two first scrapers 44 move to the end of the corresponding spiral groove 46. At this time, the two first scrapers 44 form a fan-shaped area on the filter cloth 43, and the impurities and sediments on the filter cloth 43 are concentrated in the fan-shaped area. During the process of the cylinder 41 driving the fixing member 42 and the filter cloth 43 to rise, the rubber plate 48 is pushed upward and deformed. After passing the end of the rubber plate 48, the rubber plate 48 uses its own elasticity to reset, preventing the impurities and sediments on the filter cloth 43 from falling into the lower loading bucket 12. When the cylinder 41 drives the fixing member 42 and the filter cloth 43 to fall, the rubber plate 48 is compressed downward into the deformation groove 49, so that the rubber plate 48 will not hinder the downward movement and reset of the fixing member 42 and the filter cloth 43. After passing the end of the rubber plate 48, the rubber plate 48 resets again using its own elasticity. The cylinder 41 drives During the upward movement of the first scraper 44, after the first scraper 44 contacts the collar 65, it drives the collar 65 and the first magnetic block 51 to rise synchronously. When the cylinder 41 has finished rising, the first magnetic block 51 and the second magnetic block 52 are on the same horizontal line. Due to the magnetic repulsion between them, the second magnetic block 52 drives the first ball 54 to move along the guide groove 55 and compresses the first spring 53. During the upward movement of the cylinder 41, the fixed part 42 and the filter cloth 43 come into contact with the lower ends of the second scraper 60 and the two third scrapers 61, and drive them to move upward, causing the telescopic column 56 to retract and the third spring 66 and the sliding plate 57 to move upward. When the second ball 58 is located in the corresponding sliding groove 59, the sliding plate 57 stops moving. The three springs 66 are compressed, and the lower ends of the second scraper 60 and the third scraper 61 are pressed tightly against the filter cloth 43. At the same time, the two first scrapers 44 move in a circular motion during their ascent. When they come into contact with the corresponding third scraper 61, they push the corresponding third scraper 61 inward along the limiting groove 64, and compress the second spring 62. The second scraper 60 and the third scraper 61 are initially located at the narrow end of the uncleaned fan-shaped area on the filter cloth 43. When the second magnetic block 52 moves, it will drive the second scraper 60 and the third scraper 61 to move synchronously, moving the second scraper 60 and the third scraper 61 from the narrow end of the fan-shaped area to the other end. During the movement, the elastic force of the second spring 62 keeps one end of the two third scrapers 61 pressed tightly against the corresponding first scraper 44.The impurities and sediments accumulated in the fan-shaped area of ​​the filter cloth 43 are scraped into the collection chamber 40. After scraping, the cylinder 41 drives the fixing part 42 and the filter cloth 43 to descend and reset. The first scrapers 44 on both sides also move and reset along the spiral groove 46. The first magnetic block 51 and the collar 65 are reset under the action of gravity. The first magnetic block 51 and the second magnetic block 52 repel each other. The first spring 53 elastically drives the second magnetic block 52 to reset. The second magnetic block 52 drives the second scraper 60 and the third scraper 61 to reset. The second spring 62 elastically causes the two third scrapers 61 to move in opposite directions along the limiting groove 64 to reset. The second scraper 60 moves downward and reset under the action of gravity, so that the telescopic column 56 and the sliding plate 57 are reset.
