Description

Technical Field

[0001] This utility model relates to the field of drone extension equipment technology, specifically a sampling and water collection device for drones. Background Technology

[0002] Drones, short for unmanned aerial vehicles, have become "aerial robots" thanks to their radio remote control and onboard control systems. Water sampling aims to obtain representative samples of contaminated water bodies to accurately reflect their chemical characteristics. Drones have shown great potential in this field: they can easily reach areas inaccessible to humans and quickly complete multi-point sampling; simultaneously, they avoid personnel venturing into deep water, polluted areas, and other high-risk areas, ensuring sampling safety. Drones can also carry high-precision sensors to monitor water quality in real time, and combined with GPS to accurately locate sampling points, the data is detailed and reliable. More importantly, drone sampling greatly saves manpower and material costs, and is remarkably efficient. With its unique advantages, drone water sampling is becoming the future choice in the field of water quality monitoring. However, traditional drone water sampling at low altitudes easily disturbs the water surface, affecting sampling accuracy and stability. Especially in severe weather, the scooping action faces the risk of capsizing, increasing the risk of water quality damage. Therefore, traditional water sampling methods under complex weather conditions cannot guarantee smooth operation and further affect water quality safety and sampling quality. While existing technologies may already address these issues, this project aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a sampling and water collection device for unmanned aerial vehicles (UAVs), comprising: a main shell of the UAV, a pair of connecting flight arms, and a collection support base. The pair of connecting flight arms are respectively installed on the main shell of the UAV. A water collection receiving structure is installed on the collection support base. A remote-controlled water collection structure is installed on the main shell of the UAV. The remote-controlled water collection structure comprises: a lowered power shell, a lowered power rotor, a lowered reel, a lowered steel cable, a limiting partition, a pair of fixing buckles, a sampling bottle, an external buoy, a steel cable displacement opening, a counterweight ball, a sealing coating layer, and a pair of flight fans.

[0004] The lowering power housing is installed on the main housing of the drone, the lowering power rotor is installed inside the lowering power housing and connected to the lowering reel, the main housing of the drone has a component placement slot, the lowering reel is installed inside the main housing of the drone through the component placement slot, the lowering cable is fitted on the lowering reel, the limiting partition is fixedly fitted on the outside of the lowering cable, a pair of retaining buckles are respectively installed on the limiting partition and fitted on the outside of the lowering cable, the sampling bottle has a cable displacement opening, the lowering cable is movably inserted into the cable displacement opening, the bottle outer buoy is fitted on the outside of the sampling bottle, the counterweight ball is connected to the lowering cable, and the sealing coating layer is fitted on the outside of the counterweight ball;

[0005] It should be noted that, as described above, a pair of flying fans operate, generating lift. A pair of connecting flying arms lift the main shell of the drone, and once it reaches the designated position, they drive the lowering power rotor inside the lowering power shell. This causes the lowering reel to wind around the lowering steel cable, lowering a pair of retaining clips and limiting partitions, and dropping the sampling bottle into the water. An external buoy keeps the sampling bottle afloat, while the counterweight sinks under gravity. Liquid enters the sampling bottle through the coupling gap between the bottle and the counterweight, while air flows out through the steel cable displacement opening, filling the bottle with liquid. The counterweight then returns to its original position, causing the sealing layer to close the gap in the sampling bottle and lift it above the water surface. The liquid is then firmly sealed within the bottle until the limiting partitions re-attach to the main shell of the drone, at which point the entire device flies back to its destination. The battery pack inside the main shell of the drone provides power to the entire device.

[0006] Preferably, the water receiving structure includes: a plurality of base wheels, a container body, a bottle coupling groove, and a water tap;

[0007] Several of the base wheels are respectively mounted on the collection support, the presentation box is mounted on the collection support, the presentation box is provided with the bottle coupling groove, and the water tap is mounted on the presentation box;

[0008] It should be noted that, as described above, the collection carrier can be dragged to a suitable position using the auxiliary drag handle and four base wheels on the collection carrier. The water collection device is then used to fly the sampling bottle filled with liquid to the bottle coupling slot on the presentation box, ensuring that the bottle coupling slot is fully coupled with the sampling bottle. After that, a counterweight ball is lowered, at which point the liquid in the sampling bottle will quickly flow into the presentation box. Finally, the liquid is collected and integrated in batches through the water tap. The transparent observation window on the presentation box allows for convenient observation of the liquid inside the presentation box.

[0009] Preferably, the collection support is provided with an auxiliary drag handle;

[0010] Preferably, a battery pack is installed inside the main shell of the drone;

[0011] Preferably, the lowering power housing is provided with a maintenance and inspection port;

[0012] Preferably, the presentation container is provided with a transparent observation window. Beneficial effects

[0013] This utility model provides a water sampling device for unmanned aerial vehicles (UAVs). It offers the following advantages compared to existing technologies: This device utilizes a remote-controlled water sampling structure, allowing the sampling bottle to extend flexibly and precisely below the water surface to perform water sampling. The entire process eliminates the need to scoop water, avoiding the traditional drawbacks of disturbing and tipping water during scooping. This enables direct and undisturbed sampling of the water area to be tested. Subsequently, the collected water sample is efficiently collected and systematically packaged through a water receiving structure. This series of innovative designs greatly improves the accuracy and efficiency of water sampling, ensuring a qualitative leap in sampling effectiveness. Attached Figure Description

Figure 1-3As shown, a water sampling device for a drone includes: a main drone shell 1, a pair of connecting flight arms 2, and a collection support 3. The pair of connecting flight arms 2 are respectively mounted on the main drone shell 1. A water collection receiving structure is installed on the collection support 3. A remote-controlled water collection structure is installed on the main drone shell 1. The remote-controlled water collection structure includes: a lowering power shell 4, a lowering power rotor 5, a lowering reel 6, a lowering steel cable 7, a limiting partition 8, a pair of fixing buckles 9, a sampling bottle 10, an external buoy 11, a steel cable displacement opening 12, a counterweight ball 13, a sealing coating layer 14, and a pair of flight fans 15. The lowering power shell 4 is mounted on the main drone shell 1. The lowering power rotor 5 is installed inside the lowering power shell 4 and connected to the lowering reel 6. A component placement groove is provided inside the main drone shell 1, and the lowering reel 6 is installed inside the main drone shell 1 through the component placement groove. A steel cable 7 is fitted onto the lowering reel 6. A limiting partition 8 is fixedly fitted onto the outside of the lowering steel cable 7. A pair of retaining buckles 9 are respectively installed on the limiting partition 8 and fitted onto the outside of the lowering steel cable 7. A steel cable displacement opening 12 is provided on the sampling bottle body 10. The lowering steel cable 7 is movably inserted into the steel cable displacement opening 12. An external buoy 11 is fitted onto the outside of the sampling bottle body 10. The counterweight ball 13 and the... The lowered steel cable 7 is connected, and the sealing coating layer 14 is fitted on the outside of the counterweight ball 13; the water receiving structure includes: a plurality of base wheels 16, a presentation box 17, a bottle coupling groove 18, and a water tap 19; the plurality of base wheels 16 are respectively installed on the collection support 3, the presentation box 17 is installed on the collection support 3, the presentation box 17 is provided with the bottle coupling groove 18, and the water tap 19 is installed on the presentation box 17.

[0021] According to the appendix Figure 1-3The process involves a pair of flight fans 15 generating lift, which, along with a pair of connecting flight arms 2, lifts the main shell 1 of the drone. Once the drone reaches a designated position, the lowering power rotor 5 inside the lowering power shell 4 rotates, causing the lowering reel 6 to wind around the lowering steel cable 7. This lowers the pair of retaining clips 9 and limiting partitions 8, dropping the sampling bottle 10 into the water.

The bottle 10 is raised above the water surface, and the liquid is firmly sealed inside the sampling bottle 10 until the limiting partition 8 re-attaches and resets with the main shell 1 of the drone. Then, the entire device is driven back to its destination. The battery pack installed in the main shell 1 of the drone can provide power for the entire device. The collection carrier 3 can be dragged to a suitable position by the auxiliary drag handle and four base wheels 16 on the collection carrier 3. The water collection device is operated to fly the sampling bottle 10 filled with liquid to the bottle coupling groove 18 on the presentation box 17, so that the bottle coupling groove 18 is fully coupled with the sampling bottle 10. Then, the counterweight ball 13 is lowered. At this time, the liquid in the sampling bottle 10 will flow into the presentation box 17 quickly. Finally, the liquid is collected and integrated in batches through the water tap 19. The transparent observation porthole on the presentation box 17 can facilitate the observation of the liquid in the presentation box 17.
