[0028] Please refer to Figure 3. The transmission adjustment device includes two clamping plates 18, which are slidably connected to the transmission groove 17. Each clamping plate 18 has a rubber layer on its opposite side. A water tank 19 is positioned between the two clamping plates 18. The two clamping plates 18 can clamp and fix the water tank 19, and the rubber layer can increase the friction to make the clamping plates 18 clamp the water tank 19 more stable, preventing the water tank 19 from sliding or tipping over. A second threaded rod 21 is rotatably connected inside the transmission groove 17. The surface of the second threaded rod 21 has two opposite threads. The second threaded rod 21 is connected to the internal threads of the two clamping plates 18. The two clamping plates 18 are respectively set on the two opposite threads. By rotating the second threaded rod 21 in both directions, the second threaded rod 21 can drive the two clamping plates 18 to move relative to each other or in opposite directions.
[0029] The operator rotates the second threaded rod 21, which drives the two clamping plates 18 to move relative to each other or in opposite directions, thereby adjusting the distance between the two clamping plates 18. By adjusting the distance between the two clamping plates 18, the operator can easily clamp and fix the water tank 19, improving the ease of operation and practicality of the device. This allows the operator to complete the installation and removal of the water tank without the use of tools. At the same time, the clamping force of the clamping plate structure is stable, which can firmly fix the water tank during flight or sampling, preventing shaking or falling off, and ensuring the safety and stability of the sampling process.
[0030] Please refer to Figure 2. The interior of the housing 2 is equipped with a forward and reverse motor 9. Matching the forward and reverse motor 9 are a power supply, wires, a controller, and a microcomputer structure. Since the forward and reverse motor 9 is not a major structure, it will not be described in detail. The output end of the forward and reverse motor 9 rotates through the housing 2 and extends to its exterior. The forward and reverse motor 9 is fixedly connected to a rotating shaft through a coupling. The outer wall of the rotating shaft is fixedly connected to the top of the first threaded rod 10. The output end of the forward and reverse motor 9 can drive the first threaded rod 10 to rotate forward and reverse through the rotating shaft. The first threaded rod 10 can drive the extension rod 4 to slide up and down. The extension rod 4 can drive the bracket 5 to adjust its height. By adjusting the height of the bracket 5, the water sampling tank 19 can be adjusted to the target depth for fixed-point sampling according to actual needs, realizing flexible sampling from surface water to mid-deep water, effectively improving the breadth and accuracy of water quality monitoring, and meeting the technical requirements for stratified water sampling.
[0031] Please refer to Figure 2. A drive motor 12 is installed inside the protective shell 6. The output end of the drive motor 12 rotates through the protective shell 6 and extends to its outside.

The output end of the drive motor 12 can drive the rotating rod 13 to rotate through the rotating shaft.
[0032] Please refer to Figure 4. The water tank 19 has two sets of symmetrical movable grooves 22 inside. A movable rod 23 is slidably connected inside the movable groove 22. A cover plate 20 is fixedly connected to the end of the movable rod 23 away from the movable groove 22. A slope is provided on one side of the cover plate 20. A waterproof layer is provided on the end of the cover plate 20 away from the slope. A spring 24 is fixedly connected to one side of the movable rod 23. The end of the spring 24 away from the movable rod 23 is fixedly connected to the inner wall of the movable groove 22. By moving the movable rod 23, the spring 24 can be compressed and reset.
[0033] Please refer to Figure 1. The limiting ring 8 has a sliding groove 15 extending to its outside. The cover plate 20 is slidably connected to the inside of the sliding groove 15.
[0034] The operator starts the drive motor 12 via the controller and microcomputer structure. The output of the drive motor 12 drives the rotating rod 13 to rotate via the rotating shaft. The rotating rod 13 drives the turntable 14 to rotate, and the turntable 14 drives the transmission frame 16 to rotate. The transmission frame drives the water tank 19 to rotate via two clamps 18. When a water tank 19 rotates to the bottom, the drive motor 12 is turned off. The spring 24 returns to its original position, causing the two cover plates to move away from each other and slide into the sliding groove 15 for easy water intake. After water intake is completed, the drive motor 12 is restarted. The output of the drive motor 12 continues to drive the rotating rod 13 to rotate via the rotating shaft. The rotating rod 13 drives the turntable 14 to rotate, and the turntable 14 drives the transmission frame 16 to rotate. The transmission frame drives the water collection tank 19 to rotate via two clamping plates 18. The inclined surfaces on the two cover plates 20 contact the inner wall of the sliding groove 15, causing the spring 24 to be compressed. At the same time, the two cover plates 20 move closer to each other and slide out of the sliding groove 15. The opposite sides of the two cover plates 20 are in contact with the surface of the turntable 14, and the opposite sides are tightly fitted by the waterproof layer, which can seal the water collection tank 19. By arranging and installing multiple water collection tanks 19 in sequence, water samples can be collected from multiple different locations in a single flight mission, improving the efficiency and coverage of water quality monitoring. Each water collection tank 19 is independently controlled to avoid cross-contamination between samples, ensure data accuracy, significantly reduce labor costs, and improve the level of intelligence in water quality monitoring.
[0035] Working principle: For this type of water quality monitoring drone, the staff first rotates the second threaded rod 21, which drives the two clamping plates 18 to adjust the appropriate distance to facilitate clamping and fixing the water tank 19. Then, the staff starts the drone body 1 through the external control device. After the drone body 1 flies to the designated position, the controller and microcomputer structure start the forward and reverse motor 9. The output end of the forward and reverse motor 9 drives the first threaded rod 10 to rotate through the rotating shaft. The first threaded rod 10 drives the extension rod 4 to slide up and down, and the extension rod 4 drives the bracket 5 to slide up and down, which can adjust the sampling height of different water layers.
[0036] After adjustment, the staff turns off the forward and reverse motors 9, and then starts the drive motor 12 through the controller and microcomputer structure. The output end of the drive motor 12 drives the rotating rod 13 to rotate through the rotating shaft. The rotating rod 13 drives the turntable 14 to rotate. The turntable 14 drives multiple transmission frames 16 to rotate. The transmission frames 16 can drive the water tank 19 to rotate through two clamps 18. When a water tank 19 rotates to the bottom, the drive motor 12 is turned off. Under the action of the spring 24, the two cover plates 20 move away from each other and slide into the sliding groove 15, which facilitates water intake from the water tank 19. After the water tank 19 has finished drawing water, the staff will restart the drive motor 12 to make the multiple water tanks 19 continue to rotate. The lower water tank 19 rotates and the inclined surfaces on the two cover plates 20 contact the inner wall of the sliding groove 15. The two cover plates 20 move closer to each other, and the inclined surfaces on the two cover plates 20 contact the inner wall of the sliding groove 15, causing the spring 24 to be compressed. The two cover plates 20 slide out of the sliding groove 15. At the same time, the opposite sides of the two cover plates 20 contact the surface of the turntable 14. The opposite sides of the two cover plates 20 are tightly fitted by the waterproof layer, which can seal the water tank 19.
