[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] This utility model discloses a water quality sampling drone, which mounts water quality sampling equipment on the drone. The drone provides a simple, stable, single-person-operable, and low-cost mobile platform for water sampling equipment, enabling sampling in harbors, reservoirs, lakes, and even other water bodies located in rugged terrain.

[0037] Reference Appendix Figure 1 , 2 In this utility model, the water quality sampling drone has a frame composed of front and rear crossbeams 1 and left and right side beams 2. A support plate 3 is provided between the front and rear crossbeams 1. The function of the support plate 3 is to carry the water quality sampling equipment. The front and rear crossbeams 1 are parallel to each other, and the left and right side beams 2 are parallel to each other. In order to maintain balance, the front and rear ends of the support plate 3 are respectively set in the middle of the front and rear crossbeams 1.

[0038] The drone is controlled by a remote controller. When it reaches the selected area, the water sampling drone floats on the water surface, and the sampling device 8 begins sampling. To ensure the water sampling drone floats on the water and maintains balance, floats 4 are installed below the left and right side beams 2. The floats 4 are made of low-density EPS foam material and are fixed to the side beams 2 by snap rings (this is just an example; any component that can be fixed will suffice). The floats 4 are elongated, and an underwater thruster 10 is installed below them. When the water sampling drone floats on the water surface, the underwater thruster 10 is completely submerged in the water. The remote controller sends a signal to the control device 6 (which is fixedly mounted on the support plate 3) to control the start and stop of the underwater thruster 10. This remote control method is based on existing technology and will not be described in detail here.

[0039] After sampling is completed, the water quality sampling drone needs to return to land. To ensure a stable landing, support legs 5 are evenly arranged below the front and rear crossbeams 1. The support legs 5 are fixedly connected to the crossbeams 1 through connecting plates and are located inside the floats 4.

[0040] Propellers 9 are evenly arranged above the front and rear crossbeams 1, see attached diagram. Figure 6 The propeller 9 is fixed to the crossbeam 1 by the clamp 26. The propeller 9 includes a second motor 27 and a blade 28. The blade 28 is connected to the output shaft of the second motor 27.

[0041] To enable operators to know the location of the water quality sampling drone in real time, a GPS 7 is also installed on the control device 6.

[0042] Sampling device 8 is mounted on support plate 3, see attached diagram. Figure 3 It includes an angle adjustment device and a water collection device. The angle adjustment device is used to adjust the collection depth. Water samples from different collection points can be collected in the water collection device, or water samples from different depths at the same collection point can be collected in the water collection device.

[0043] The angle adjustment device, namely the angle adjuster 12, is shown in the attached figure. Figure 4 The angle adjuster 12 has a base 18, and rotating shafts 19 are provided on both sides of the base 18. The base 18 is fixedly connected to one end of the straight tube 20. Fixing blocks 21 are provided on both sides of the connection end between the straight tube 20 and the base 18. The fixing blocks 21 are sleeved and fixed on the straight tube 20.

[0044] Motor 22 is also provided on both sides of the straight tube 20. The output shaft of motor 22 is fixedly connected to one end of connecting rod 23. The other end of connecting rod 23 is hinged to one end of connecting rod 24. The other end of connecting rod 24 is hinged to the fixed block 21. Motor 22 drives the straight tube 20 to rotate through the connecting rod structure. Hole 25 is also provided on the straight tube 20.

[0045] Reference Appendix Figure 3 The angle adjuster 12 is fixedly connected to the support plate 3 via the mounting frame 11, and the angle adjuster 12 is located below the support plate 3. The base 18 is hinged to the mounting frame 11 via the rotating shafts 19 on both sides, and the base 18 can drive the straight tube 20 to rotate around the mounting frame 11. The motors 22 on both sides are fixed to the outside of the mounting frame 11, and their output shafts pass through the mounting frame 11 and are fixed to the connecting rod 23.

[0046] The water collection device is located above the mounting frame 11, see attached diagram. Figure 3 , 5 The water collection device includes an inlet pipe 13, a water pump 14, a liquid distribution pipe 15, a water distribution pipe 16, and a water collection bottle 17. The output end of the water pump 14 is connected to the liquid distribution pipe 15, the liquid distribution ports on both sides of the liquid distribution pipe 15 are connected to one end of the water distribution pipe 16, and the other end of the water distribution pipe 16 is connected to the top of the water collection bottle 17.

[0047] The water pump 14 draws water in through the inlet pipe 13, and then sends the water into the designated water collection bottle 17 through the liquid distribution pipe 15 and the independent water distribution pipe 16.

[0048] The water pump 14 and the liquid distribution pipe 15 are both fixed on the support plate 3. Multiple water bottle brackets are fixed on both sides of the support plate 3 to hold multiple water collection bottles 17.

[0049] Reference Appendix Figure 1 ,2 The control device 6 is located in the middle of the water quality sampling drone, and a battery is also installed on it to supply power to various components. The function of the control device 6 is to control the start, adjustment and shutdown of the propeller 9, the start, adjustment and shutdown of the underwater thruster 10, the start, adjustment and shutdown of the motor 22, and the opening and closing state of the liquid separator 15. Since the above control methods are not creatively designed and all adopt existing technologies, the purpose is to achieve the above control, so they are not described in detail in this utility model.
