Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) water sampling devices, and particularly to a multi-point UAV water sampling device with compartmentalized storage. Background Art

[0002] In many fields such as environmental monitoring and water quality research, the demand for water sample collection is increasing day by day. Traditional water sample collection methods, such as manual collection by boat, not only consume a lot of manpower and material resources, but also are difficult to implement in some areas with complex terrain and dangerous areas. With the development of UAV technology, UAV water sampling devices have emerged, bringing great convenience to water sample collection work. It can quickly reach the designated water area, overcome geographical environment limitations, and greatly improve the collection efficiency.

[0003] Currently, most common UAV water sampling devices adopt a single water tank design. Its working principle is usually to lower a single water tank to the water surface for water sampling through a simple rope retraction mechanism, and then lift the water tank onto the UAV.

[0004] However, this single-tank UAV water sampling device has many problems in practical applications. For example, when collecting water samples at multiple points in a relatively large water area, due to only one water tank, the UAV needs to make multiple round trips to different sampling points. This results in a huge consumption of the UAV's power, greatly shortening its effective working time. At the same time, multiple round trips increase the flight time and distance, not only reducing the collection efficiency, but also increasing the risk of failure due to long-term flight. In addition, the existing devices also have deficiencies in terms of complex installation and structural stability. When flying in a complex environment, problems such as water tank loosening and connection component detachment may occur, affecting the normal progress of water sampling work. Therefore, the present invention provides a multi-point UAV water sampling device with compartmentalized storage to solve the deficiencies existing in the prior art. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a multi-point UAV water sampling device with compartmentalized storage, which solves the problems of complex installation of the UAV water sampling device in the prior art and the time and energy consumption for multi-point collection.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: An unmanned aerial vehicle multi-point water collection device with a compartmentalized storage structure, comprising a protective upper cover and a plurality of water tanks. A protective lower cover is provided at the bottom of the protective upper cover. A data interface is provided on one side of the outer part of the protective upper cover. Two card holes are provided on the outer side of the protective upper cover. An assembly mechanism is slidably connected to the outer side of the protective upper cover. The assembly mechanism includes a combined block. The outer side of the combined block is slidably connected to the outer side of the protective upper cover. Two clamping blocks are slidably connected inside the combined block. One end of each clamping block is fixedly connected to a first spring. One end of the first spring is fixedly connected to the inner wall of the combined block. The outer part of the clamping block is engaged inside the card hole.

[0007] Preferably, a plurality of collection mechanisms are installed inside the protective lower cover. The collection mechanism includes a motor and a rope position detection column. The motor is installed inside the protective lower cover, and a circuit board is installed inside the protective lower cover and electrically connected to the motor.

[0008] Preferably, a plurality of rope winding discs are fixedly connected inside the protective lower cover. A rope is arranged inside the rope winding disc, and one end of the rope is fixedly connected to the output end of the motor. One end of the rope position detection column is fixedly connected to the bottom of the protective lower cover and is located directly below the corresponding rope winding disc.

[0009] Preferably, the water tank is located below the protective lower cover. An arc-shaped clamping plate is provided on the outer side of the water tank. A second spring is fixedly connected to the inner side of the arc-shaped clamping plate. One end of the second spring is fixedly connected to a pressing plate. Two limiting holes are provided inside the pressing plate.

[0010] Preferably, a grasping mechanism is provided on the outer side of the arc-shaped clamping plate. The grasping mechanism includes a base. The bottom of the base is attached to the top of the arc-shaped clamping plate. A conical detection head is fixedly connected to the top of the base.

[0011] Preferably, an annular groove is provided on the outer circumference of the conical detection head. The other end of the rope is wound around the outer circumference of the annular groove.

[0012] Preferably, two tension spring telescopic rods are arranged inside the base. One end of each tension spring telescopic rod is fixedly connected to an L-shaped plate. The outer side of the L-shaped plate is attached to the outer side of the arc-shaped clamping plate. A limiting column is fixedly connected to the outer side of the L-shaped plate. The outer part of the limiting column is engaged inside the limiting hole. The outer side of the pressing plate is attached to the outer side of the L-shaped plate.

[0013] Preferably, fixing rings are fixedly connected to both the top and bottom of the water tank. An activity disc is provided on the top of the lower fixing ring. A plurality of flag-shaped blocks are fixedly connected to the top of the fixing ring, and the outer side of the activity disc is slidably connected to the outer sides of the plurality of flag-shaped blocks.

[0014] The present invention provides a multi-point water collection device for drones with compartment-type storage.

[0015] Beneficial effects:

[0016] 1. The assembly mechanism of the water collection device in the present invention is cleverly designed. The component used to connect with the drone can be simply fixed on the drone by screws, and the connection between the protective cover and the component is achieved through a special snap-fit ​​structure. This snap-fit ​​structure uses the elastic force of the spring. After the component slides into place, the snap-fit ​​parts can be quickly and firmly stuck to each other. Without a complicated installation process, it can ensure that the water collection device remains stable during the flight of the drone and will not fall off due to factors such as vibration, which greatly improves the installation efficiency and safety.

[0017] 2. The collecting mechanism of the water sampling device of the present invention and the water tank-related structure work together to ensure the accuracy and reliability of water sample collection. The motor is precisely controlled by the circuit board and can accurately adjust the retraction and release of the rope, thereby controlling the lifting height of the water tank. The special structure inside the water tank, such as the components that cooperate with the movable disk, can allow water to enter smoothly when the water tank is placed in the water, and can effectively seal when the water tank is lifted to prevent water sample leakage. In addition, the structure for detecting the position of the rope can ensure its stability during the lifting process of the water tank to avoid the influence of factors such as shaking on the water sampling effect, thereby ensuring that the collected water samples have high accuracy and integrity.

[0018] 3. The present invention adopts a design of storing multiple water tanks in separate compartments, so that the UAV can collect water from multiple points during one flight. Compared with the traditional method of collecting water a single time and then making multiple round trips to collect water, the total distance and number of round trips of the UAV flight are greatly reduced. This not only effectively saves the power consumption of the UAV and improves the energy utilization efficiency, but also can collect more water samples with the same amount of power, greatly improving the overall efficiency of the water collection work and reducing time and energy costs.

[0026] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to the attached Figure 1 - attached Figure 6 , the embodiment of the present invention provides a multi-point water sampling device for an unmanned aerial vehicle with a compartmented storage structure, including an upper protective cover 1 and a plurality of water tanks 21. A lower protective cover 2 is provided at the bottom of the upper protective cover 1. A data interface 3 is opened on one side of the outer part of the upper protective cover 1. Two card holes 4 are opened on the outer side of the upper protective cover 1. An assembly mechanism is slidably connected to the outer side of the upper protective cover 1. The assembly mechanism includes a combined block 5. The outer side of the combined block 5 is slidably connected to the outer side of the upper protective cover 1. Two card blocks 6 are slidably connected inside the combined block 5. One end of the card block 6 is fixedly connected to a first spring 7. One end of the first spring 7 is fixedly connected to the inner wall of the combined block 5. The outer part of the card block 6 is clamped inside the card hole 4.

[0028] Specifically, when the combined block 5 is slidably connected to the outer side of the upper protective cover 1, its design purpose is to facilitate the installation of the multi-point water sampling device for the unmanned aerial vehicle with a compartmented storage structure on the unmanned aerial vehicle. The combined block 5 is tightened on the unmanned aerial vehicle by screws. When installing the upper protective cover 1, since one end of the card block 6 is fixedly connected to the first spring 7 and one end of the first spring 7 is fixedly connected to the inner wall of the combined block 5, when the upper protective cover 1 slides along the outer side of the combined block 5, it will squeeze the arc surface of the card block 6. Using the special arc surface shape of the card block 6, it will contract into the combined block 5 against the elastic force of the first spring 7. When the card block 6 moves to the position corresponding to the card hole 4, the elastic force of the first spring 7 will quickly pop out the card block 6, and the card block 6 will be stuck into the card hole 4, realizing the stable installation of the upper protective cover 1 and the combined block 5. The setting position and size of the card hole 4 match the card block 6, ensuring that the two can be accurately clamped, thereby ensuring the reliability of the entire assembly mechanism.

[0029] Please refer to the attached Figure 1 - Attachment Figure 6 , multiple receiving mechanisms are installed inside the protective lower cover 2. The receiving mechanism includes a motor 8 and a rope position detection column 10. The motor 8 is installed inside the protective lower cover 2, and a circuit board is installed inside the protective lower cover 2 and electrically connected to the motor 8. A plurality of rope winding discs 9 are fixedly connected inside the protective lower cover 2. A rope is arranged inside the rope winding disc 9, and one end of the rope is fixedly connected to the output end of the motor 8. One end of the rope position detection column 10 is fixedly connected to the bottom of the protective lower cover 2 and is located directly below the corresponding rope winding disc 9.

[0030] Specifically, the motor 8 is installed inside the protective lower cover 2. A circuit board is also installed inside the protective lower cover 2. The circuit board and the motor 8 are electrically connected through connection methods such as wires, so that the circuit board can control the working states of the motor 8, such as starting, stopping, and speed. A plurality of rope winding discs 9 are fixedly installed inside the protective lower cover 2, and each rope winding disc 9 has its own independent rope. The output end of the motor 8 is fixedly connected to one end of the rope. When the motor 8 rotates, it will drive the rope to perform the winding and unwinding operations. One end of the rope position detection column 10 is fixedly connected to the bottom of the protective lower cover 2, and its position is directly below the corresponding rope winding disc 9. The rope position detection column 10 plays an important role in position detection and stability during the operation of the entire device. When the water tank 21 descends or ascends along with the rope, its final state will cause the top part of the conical detection head 12 to be stuck inside the rope position detection column 10, ensuring that during the flight of the drone, the rope position detection column 10 can remain stable and will not shake easily, guaranteeing the accuracy of the rope position, and thus ensuring the normal lifting and lowering and sampling operations of the water tank 21.

[0031] Please refer to the attached Figure 1 - Attachment Figure 6, the water tank 21 is located below the protective lower cover 2. An arc-shaped clamping plate 17 is arranged on the outer side of the water tank 21. A second spring 18 is fixedly connected to the inner side of the arc-shaped clamping plate 17. One end of the second spring 18 is fixedly connected to a pressing plate 19. Two limiting holes 20 are formed inside the pressing plate 19. A grasping mechanism is arranged on the outer side of the arc-shaped clamping plate 17. The grasping mechanism includes a base 11. The bottom of the base 11 is attached to the top of the arc-shaped clamping plate 17. A conical detection head 12 is fixedly connected to the top of the base 11. An annular groove 13 is formed on the outer circumference of the conical detection head 12. The other end of the rope is wound around the outer circumference of the annular groove 13. Two tension spring telescopic rods 14 are arranged inside the base 11. One end of the tension spring telescopic rod 14 is fixedly connected to an L-shaped plate 15. The outer side of the L-shaped plate 15 is attached to the outer side of the arc-shaped clamping plate 17. A limiting column 16 is fixedly connected to the outer side of the L-shaped plate 15. The outside of the limiting column 16 is engaged inside the limiting hole 20. The outer side of the pressing plate 19 is attached to the outer side of the L-shaped plate 15. Fixed rings 22 are fixedly connected to both the top and the bottom of the water tank 21. A movable disc 23 is arranged on the top of the lower fixed ring 22. A plurality of flag-shaped blocks 24 are fixedly connected to the top of the fixed ring 22. The outer side of the movable disc 23 is slidably connected to the outer sides of the plurality of flag-shaped blocks 24.

[0032] Specifically, the water tank 21 is located below the protective lower cover 2. The arc-shaped clamping plate 17 provided on its outer side is for connecting with the grasping mechanism. The spring two 18 fixedly connected to the inner side of the arc-shaped clamping plate 17, and the pressing plate 19 fixedly connected to one end thereof is a key component. The two limiting holes 20 opened inside the pressing plate 19 cooperate with the limiting posts 16 fixedly connected to the outer side of the L-shaped plate 15 in the grasping mechanism. When installing the grasping mechanism, first pull the two L-shaped plates 15 to overcome the elastic force of the tension spring telescopic rod 14, place the base 11 on the top of the arc-shaped clamping plate 17. When the two L-shaped plates 15 are released, the elastic force of the spring two 18 pushes the pressing plate 19 to move upward. At the same time, the outer sides of the two L-shaped plates 15 will move to the bottom of the pressing plate 19. At this time, the two limiting holes 20 and the two limiting posts 16 are engaged, realizing the connection between the grasping mechanism and the water tank 21. In the grasping mechanism, the bottom of the base 11 fits with the top of the arc-shaped clamping plate 17 to ensure the tightness of the connection. The conical detection head 12 fixedly connected to the top of the base 11, and the annular groove 13 opened on its outer circumference is used to wind the other end of the rope. When the rope is wound outside the annular groove 13, the rotation of the motor 8 can drive the water tank 21 to perform lifting operations. The fixed rings 22 fixedly connected to both the top and the bottom of the water tank 21 play a role in strengthening the structure of the water tank 21 and connecting other components. The movable disk 23 provided on the top of the lower fixed ring 22 cooperates with the multiple flag-shaped blocks 24 fixedly connected to the top of the fixed ring 22. The outer side of the movable disk 23 is slidably connected to the outer sides of the multiple flag-shaped blocks 24. When the water tank 21 descends into the water area, the water will push up the movable disk 23, so that the water enters the inside of the water tank 21. When the water tank 21 is lifted again, the gravity of the water will press the movable disk 23 against the outer side of the lower fixed ring 22, blocking the central area thereof, achieving a sealing effect, and completing the collection and storage of water samples.

[0033] Working principle: First, the combination block 5 can be screwed onto the drone. Then, slide the upper protective cover 1 to squeeze the arc surface of the clamping block 6, causing the clamping block 6 to contract into the interior of the combination block 5. When the clamping block 6 moves to the position corresponding to the clamping hole 4, the elastic force of the first spring 7 causes the clamping block 6 to quickly pop out, and the clamping block 6 will snap into the interior of the clamping hole 4 to complete the installation. Then, after pulling the two L-shaped plates 15, place the base 11 on the top of the arc-shaped clamping plate 17. When the two L-shaped plates 15 are released, push the pressing plate 19 upward. Then, the outer sides of the two L-shaped plates 15 will move to the bottom of the pressing plate 19. Under the elastic force of the second spring 18, the pressing plate 19 will press down, causing the two limiting holes 20 to engage with the two limiting posts 16. Then, wind one end of the rope around the outer side of the annular groove 13 to complete the installation of the entire device. Control different motors 8 to work respectively through the circuit board inside the lower protective cover 2. When the drone flies to the corresponding water area, start the motor 8 to loosen the rope, so that the water tank 21 moves downward and falls into the water. The water will push up the movable disk 23 and enter the interior of the water tank 21. Then, lift the water tank 21. The water will press the movable disk 23 against the outer side of the lower fixing ring 22 to block the central area, thus completing the sampling. Then, the water tank 21 will continue to move upward until the top part of the conical detection head 12 is stuck inside the rope position detection post 10, so as to ensure that the rope position detection post 10 has better stability and will not shake easily during the flight of the drone.
