Description

Technical Field

[0001] This utility model belongs to the technical field of air collection devices, and specifically relates to an ambient air collection device for unmanned aerial vehicles. Background Technology

[0002] With the increasing demand for environmental protection and air quality monitoring, it has become increasingly important to collect atmospheric samples from specific spatial areas, especially from high altitudes, pollution core areas, or complex terrains that are difficult for humans to directly access. UAVs, with their flexible maneuverability and wide airspace coverage, provide an ideal mobile platform for efficiently completing such environmental air sampling tasks.

[0003] Traditional air sampling devices mounted on drones often employ the active pump principle. This requires continuous power consumption during drone flight to drive the sampling pump, thus reducing the drone's endurance. Furthermore, the active pump structure is difficult to clean, severely impacting the accuracy of subsequent data collection and analysis. To address these issues, an ambient air sampling device for drones is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an ambient air sampling device for unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art. Traditional active pump-suction sampling devices require continuous power consumption to drive the sampling pump during UAV flight, thereby reducing the UAV's endurance. In addition, the active pump-suction structure is inconvenient to clean, which seriously affects the accuracy of subsequent data collection and analysis.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ambient air collection device for unmanned aerial vehicles (UAVs), comprising a mounting plate, two first mounting brackets fixedly connected to the top of the mounting plate, a threaded shaft rotatably connected to one side of each first mounting bracket, a motor fixedly connected to one side of the mounting plate, the output end of the motor being bolted to the threaded shaft via a coupling, a movable block being threadedly connected to the surface of the threaded shaft, a locking block being fixedly connected to the top of the movable block, a bottle body being provided on the top of the mounting plate, end caps being threadedly connected to both ends of the bottle body, an air inlet pipe being slidably connected inside the end caps, an air inlet hole being provided on the surface of the air inlet pipe, a connector being fixedly connected to one end of the air inlet pipe, the surface of the connector engaging with the locking block, a spring being sleeved on the surface of the air inlet pipe, and a fixing nut being threadedly connected to the surface of the air inlet pipe.

[0006] Preferably, a sealing gasket is fixedly connected to one side of the connector, and a one-way valve is threadedly connected to the inside of the end cap.

[0007] Preferably, a second mounting bracket is hinged to the top of the first mounting bracket, a U-shaped block is fixedly connected to the front of the second mounting bracket, a screw is hinged to the front of the first mounting bracket, and a wing nut is threaded onto the surface of the screw.

[0008] Preferably, two slide rods are fixedly connected to one side of the first mounting bracket, the other end of the slide rods is fixedly connected to the mounting plate, the interior of the movable block is slidably connected to the slide rods, and the interior of the movable block has a circular hole adapted to the slide rods.

[0009] Preferably, mounting blocks are fixedly connected to both sides of the front and back of the mounting plate, and mounting bolts are sleeved inside the mounting blocks.

[0010] This utility model has the following beneficial effects: This device creates a negative pressure environment by pre-vacuuming the inside of the bottle, and then uses a motor-driven threaded shaft to precisely move the moving block and connector. This allows the air inlet pipe to slide within the end cap and compress the spring, enabling the air inlet channel to open quickly after the drone arrives at the sampling area. The pressure difference allows ambient air to enter the bottle efficiently, enabling rapid air sample collection. Simultaneously, the forward and reverse rotation of the motor and the spring's reset action ensure the automatic and rapid closure and reset of the air inlet pipe. This device not only significantly improves the speed, efficiency, and accuracy of drone sampling but also reduces the impact on drone battery life. Its simple structural design also ensures ease of maintenance and cleaning. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Example 1: refer to Figure 1-4 An ambient air collection device for unmanned aerial vehicles (UAVs) includes a mounting plate 1. Two first mounting brackets 2 are fixedly connected to the top of the mounting plate 1. A threaded shaft 3 is rotatably connected to one side of the first mounting bracket 2. A motor 4 is fixedly connected to one side of the mounting plate 1. The output end of the motor 4 is bolted to the threaded shaft 3 via a coupling. A movable block 5 is threadedly connected to the surface of the threaded shaft 3. A locking block 6 is fixedly connected to the top of the movable block 5. A bottle body 7 is provided on the top of the mounting plate 1. Both ends of the bottle body 7 are threadedly connected to end caps 8. An air inlet pipe 9 is slidably connected inside the end caps 8. An air inlet hole 10 is opened on the surface of the air inlet pipe 9. A connector 11 is fixedly connected to one end of the air inlet pipe 9. The surface of the connector 11 is locked with the locking block 6. A spring 12 is sleeved on the surface of the air inlet pipe 9. A fixing nut 13 is threadedly connected to the surface of the air inlet pipe 9.

[0015] Specifically, the device creates a negative pressure environment by pre-vacuuming the inside of the bottle body 7, and combines this with the motor 4 driving the threaded shaft 3 to precisely move the moving block 5 and connector 11, allowing the air inlet pipe 9 to slide inside the end cap 8 and compress the spring 12. This enables the air inlet channel to open quickly after the drone arrives at the sampling airspace, allowing ambient air to enter the bottle body 7 efficiently using the pressure difference, thus achieving rapid air sample collection. At the same time, the forward and reverse rotation control of the motor 4 and the reset action of the spring 12 achieve automatic closure and rapid reset of the air inlet pipe 9. This not only significantly improves the response speed and efficiency of drone sampling in complex airspace, but also effectively reduces the risk of external interference and sample contamination during the sampling process, and improves the accuracy and reliability of ambient air collection. For cleaning, the end cap 8 is unscrewed from both ends of the bottle body 7, and the fixing nut 13 is screwed off from the surface of the air inlet pipe 9, allowing the air inlet pipe 9 to be pulled out from inside the end cap 8, thus facilitating the disassembly and cleaning of the sampling part.

[0016] refer to Figure 3 and Figure 4 A sealing gasket 14 is fixedly connected to one side of the connector 11, which can improve the sealing between the connector 11 and the end cap 8. A one-way valve 15 is connected to the internal thread of the end cap 8, which can facilitate the vacuuming of the device.

[0017] refer to Figure 2 The top of the first mounting bracket 2 is hinged to the second mounting bracket 17. The front of the second mounting bracket 17 is fixedly connected to the U-shaped block 18. The front of the first mounting bracket 2 is hinged to the screw 19. The surface of the screw 19 is threaded with a wing nut 20. By inserting the screw 19 into the U-shaped block 18 and then turning the wing nut 20, the second mounting bracket 17 and the first mounting bracket 2 can be fixedly connected. The end cap 8 and the bottle body 7 can be fixedly installed by the second mounting bracket 17 hinged to the top of the first mounting bracket 2.

[0018] refer to Figure 2and Figure 3 Two sliding rods 21 are fixedly connected to one side of the first mounting bracket 2. The other end of the sliding rod 21 is fixedly connected to the mounting plate 1. The inside of the moving block 5 is slidably connected to the sliding rod 21. The inside of the moving block 5 is provided with a round hole that matches the sliding rod 21. Through the sliding rod 21 and the round hole, the stable movement of the moving block 5 can be effectively improved.

[0019] refer to Figure 2 Mounting blocks 22 are fixedly connected to both sides of the front and back of the mounting plate 1. Mounting bolts 16 are installed inside the mounting blocks 22. By setting the mounting bolts 16, the device can be effectively installed with the drone.

[0020] Brief description of usage: The user can install the mounting plate 1 to the drone using the mounting bolts 16. Then, the vacuum pump evacuates the inside of the bottle body 7 through the one-way valve nozzle 15. The end cap 8 is fixed by the second mounting bracket 17 and the first mounting bracket 2. At the same time, the connector 11 is inserted into the inside of the locking block 6. When the drone flies to the sampling airspace, the motor 4 is started to drive the threaded shaft 3 to rotate forward. The threaded shaft 3 drives the moving block 5 and the connector 11 to move. The sealing gasket 14 drives the air inlet pipe 9 to slide inside the end cap 8. At the same time, the air inlet pipe 9 compresses the spring 12 through the fixing nut 13. Ambient air enters the inside of the bottle body 7 through the air inlet hole 10 and the air inlet pipe 9. Then, the motor 4 reverses to drive the locking block 6 to reset. At the same time, the spring 12 drives the screw 19 to reset through the fixing nut 13, so that the drone can quickly collect ambient air.
