Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV for water quality sampling. Background Technology

[0002] In fields such as water environment monitoring, water resource protection, and pollution control, water quality sampling is a crucial step in obtaining basic data. The representativeness and accuracy of the samples directly affect the reliability of subsequent testing and analysis results. Traditional water quality sampling largely relies on manual operation. Testing personnel must carry sampling tools to the monitoring point and complete the sampling by boat, bridge, or direct wading. This method is not only inefficient but also presents challenges such as high operational difficulty, high cost, and poor safety when facing remote water areas, complex terrain (such as deep ditches and swamps), or heavily polluted dangerous water areas, making it difficult to meet the needs of large-scale, high-frequency water quality monitoring. With the rapid development of drone technology, its advantages of flexibility, wide coverage, and remote control have led to its increasing application in water quality sampling. Drone water quality sampling equipment typically carries a sampling container, enabling rapid arrival at the target water area and water sample collection, effectively overcoming the spatial limitations of manual sampling and significantly improving sampling efficiency and operational safety.

[0003] However, existing drone sampling devices often use open or simply covered sampling containers. After sampling, changes in the drone's attitude during flight (such as tilting or vibration) can easily cause water sample spillage, resulting in sample loss. Simultaneously, due to the lack of a reliable sealing mechanism, pollutants such as outside air, dust, and bird droppings can easily enter the sampling container, contaminating the collected water sample and causing sample distortion. This deficiency directly affects the accuracy of sampling results, especially in monitoring scenarios requiring precise analysis of trace pollutants, potentially leading to misjudgments. In natural water bodies, sampling points are often surrounded by debris such as aquatic plants, branches, and floating garbage. The sampling ports of existing drone sampling devices are usually directly exposed. As the sampling container descends to the water surface, these debris can easily hinder the descent of the sampling port and cause it to come into contact with the water surface, potentially leading to sampling failure. Therefore, a new type of drone for water quality sampling is needed to address the problems existing in current technologies. Utility Model Content

[0004] The purpose of this invention is to provide a drone for water quality sampling to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality sampling drone, comprising a drone body, an equipment box fixed to the bottom of the drone body, a sampling tube disposed below the equipment box, a sealing mechanism disposed at the upper end of the sampling tube, the sealing mechanism comprising a first baffle and a second baffle, both the first baffle and the second baffle being disposed above the sampling tube, an adjusting slide fixed to the side surface of both the first baffle and the second baffle, an adjusting slider fixed to the upper end of the adjusting slide, and a synchronous adjusting component disposed inside the equipment box.

[0006] Preferably, the adjustment slider is slidably connected to the bottom of the UAV body, and the lower end of the adjustment slide is fixed with a water entry lever.

[0007] Preferably, a sealing gasket is fixed on the inner wall of the first baffle and the second baffle, a suspension threaded rod is provided between the first baffle and the second baffle, an internal threaded seat is fixed at the center of the inner bottom wall of the sampling tube, and the lower end of the suspension threaded rod is threaded through the inside of the internal threaded seat.

[0008] Preferably, a sealing ring is fixed to the upper end face of the sampling tube, and the upper end of the suspension threaded rod is fixed to the bottom of the equipment box.

[0009] Preferably, the synchronization adjustment component includes a bidirectional threaded rod, which is rotatably connected to a rotating base inside the UAV body. A driven gear is fixedly sleeved on the middle section of the bidirectional threaded rod. A drive motor is fixed inside the device box, and a drive gear is fixedly sleeved on the surface of the output shaft of the drive motor.

[0010] Preferably, the driven gear meshes with the driving gear, the surface of the bidirectional threaded rod is symmetrically provided with bidirectional helical patterns, and the two adjusting sliders are symmetrically arranged on the two helical patterns of the bidirectional threaded rod.

[0011] This utility model provides a drone for water quality sampling, which has the following advantages compared with the prior art:

[0012] Through precise control of the synchronous adjustment component, the drive motor rotates the bidirectional threaded rod, causing the two adjustment sliders to move the first and second baffles synchronously closer or further apart, thus flexibly controlling the opening and closing of the sampling tube inlet. During the drone's water collection flight, when the first and second baffles move closer together to close the inlet, it effectively prevents the water sample in the sampling tube from spilling due to the drone's unstable flight, preventing leakage during transportation or transfer, and preventing external contaminants from entering the sampling tube, ensuring the integrity and cleanliness of the collected water sample, and improving the reliability of the sampling results.

[0013] With its specially designed water-entry levers, the two levers provide excellent support on both sides of the sampling tube as it descends, moving away from the first and second baffles. This design effectively clears away debris such as weeds, branches, and floating garbage near the water intake point, preventing these objects from entangled or clogging the sampling tube. This ensures that the upper end of the sampling tube smoothly contacts the water surface and completes the water intake, significantly reducing water intake failures caused by debris interference and improving the sampling success rate of drones in complex aquatic environments.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a water quality sampling drone, including a drone body 1, an equipment box 2 fixed to the bottom of the drone body 1, a sampling tube 3 disposed below the equipment box 2, and a sealing mechanism 4 disposed at the upper end of the sampling tube 3. The sealing mechanism 4 includes a first baffle 5 and a second baffle 6, both of which are disposed above the sampling tube 3. Adjustment slides 7 are fixed to the side surfaces of both the first baffle 5 and the second baffle 6, and adjustment sliders 8 are fixed to the upper end of the adjustment slides 7. A synchronous adjustment component 9 is disposed inside the equipment box 2. When the first baffle 5 and the second baffle 6 are close to each other, the water inlet of the sampling tube 3 is closed; when they are far apart, the water inlet is open. It is worth noting that the positions of the first baffle 5 and the second baffle 6 above the sampling tube 3 are flexibly adjustable, thereby precisely controlling the opening and closing of the upper port of the sampling tube 3. This design can effectively reduce the spillage problem of the sampling tube 3 due to unstable flight status during the water collection process of the drone body 1, ensuring the stability of sampling.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the adjustment slider 8 is slidably connected to the bottom of the drone body 1, and the lower end of the adjustment carriage 7 is fixed with a water entry lever 13. When the drone body 1 flies to the water collection point to collect water, the lower ends of the sampling tube 3 and the water entry lever 13 will first penetrate the water surface. During the process of the drone body 1 driving the sampling tube 3 to descend, the drive motor 18 will drive the first baffle 5 and the second baffle 6 to adjust away from each other. At this time, the two water entry levers 13 on both sides of the sampling tube 3 will play a supporting role, effectively clearing away water plants, branches, floating garbage and other debris near the water collection point, preventing these objects from entangled or blocking the sampling tube 3, ensuring that the upper end of the sampling tube 3 can smoothly contact the water surface and complete the water collection action, greatly reducing the probability of water collection failure due to debris interference.

[0022] Further as Figure 3 As shown, it is worth noting that a sealing gasket 14 is fixed on the inner wall of the first baffle 5 and the second baffle 6, and a suspension threaded rod 15 is inserted between the first baffle 5 and the second baffle 6. An internal threaded seat 16 is fixed at the center of the inner bottom wall of the sampling tube 3, and the lower end of the suspension threaded rod 15 is threaded inside the internal threaded seat 16. Before use, the sampling tube 3 is spirally fitted onto the suspension threaded rod 15 through the internal threaded seat 16 to complete the assembly preparation.

[0023] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a sealing ring 17 is fixed to the upper end face of the sampling tube 3, and the upper end of the suspension threaded rod 15 is fixed to the bottom of the equipment box 2.

[0024] Further as Figure 4 As shown, it is worth noting that the synchronous adjustment component 9 includes a bidirectional threaded rod 10, which is rotatably connected to a rotating base inside the UAV body 1. A driven gear 11 is fixedly sleeved on the middle section of the bidirectional threaded rod 10. A drive motor 18 is fixed inside the device box 2, and a drive gear 12 is fixedly sleeved on the surface of the output shaft of the drive motor 18. The driven gear 11 and the drive gear 12 are meshed together. The surface of the bidirectional threaded rod 10 is symmetrically decorated with bidirectional helical patterns, and two adjustment sliders 8 are symmetrically arranged on the two helical patterns of the bidirectional threaded rod 10. In use, when the drive motor 18 is turned on, its driving force will drive the drive gear 12 to rotate. Because the drive gear 12 and the driven gear 11 are meshed together, the driven gear 11 will move in tandem, thereby driving the bidirectional threaded rod 10 to rotate at a fixed point inside the UAV body 1. Since the surface of the bidirectional threaded rod 10 is provided with symmetrical bidirectional spiral patterns, and the two adjusting sliders 8 are respectively threaded on the two spiral patterns of the threaded rod, the rotating threaded rod will drive the two adjusting sliders 8 to move closer to each other or further away from each other along the slide of the bottom of the UAV body 1.

[0025] This solution has the following working process: Before use, the sampling tube 3 is spirally sleeved on the suspension threaded rod 15 through the internal threaded seat 16. When in use, the drive motor 18 is turned on, and the drive motor 18 drives the active gear 12 to rotate. Since the active gear 12 is meshed with the driven gear 11, the driven gear 11 and the bidirectional threaded rod 10 are driven to rotate at a fixed point inside the UAV body 1. Since the surface of the bidirectional threaded rod 10 is symmetrically provided with bidirectional spiral patterns, and the two adjusting sliders 8 are respectively threaded on the two sections of the bidirectional threaded rod 10, the two adjusting sliders 8 can be driven to move closer or further away from each other along the slide at the bottom of the UAV body 1. Thus, when the first baffle 5 and the second baffle 6 move closer to each other, they close the water inlet of the sampling tube 3. When the first baffle 5 and the second baffle 6 move further away from each other, they open the water inlet of the sampling tube 3. The first baffle 5 and the second baffle 6 are located above the sampling tube 3 and can be flexibly adjusted to control the opening and closing state of the upper port of the sampling tube 3, thereby reducing the trouble of spillage of the sampling tube 3 during the unstable flight of the UAV body 1 to collect water.

[0026] Before the drone body 1 flies to the water collection point to collect water, the lower ends of the sampling tube 3 and the water entry lever 13 penetrate the water collection surface. As the drone body 1 drives the sampling tube 3 to descend, the drive motor 18 drives the first baffle 5 and the second baffle 6 to move away from each other. In this way, the two water entry levers 13 play a supporting role on both sides of the sampling tube 3, effectively clearing away water plants, branches, floating garbage and other debris near the water collection point, preventing these objects from getting tangled and blocking the sampling tube, ensuring that the upper end of the sampling tube 3 can smoothly contact the water surface and complete the water collection action, reducing water collection failure caused by debris interference.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
