Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and more specifically, to a drone-based water quality testing device. Background Technology

[0002] Water quality testing is a crucial step in ensuring water resource safety, protecting the environment, and safeguarding human health. Ammonia nitrogen is one of the main nitrogen sources of eutrophication in water bodies. Excessive ammonia nitrogen leads to the proliferation of algae and other aquatic plants, causing algal blooms. This not only consumes large amounts of dissolved oxygen but also reduces the water body's self-purification capacity, potentially leading to oxygen depletion and even the formation of "dead water zones," severely damaging the ecosystem. Therefore, testing the ammonia nitrogen content in water is an important aspect of water quality assessment.

[0003] Generally, the detection method for ammonia nitrogen in water bodies often involves manual sampling followed by laboratory testing. However, this method cannot quickly determine whether the ammonia nitrogen content in the water body exceeds the standard. When multiple water bodies need to be tested, a large number of samples need to be taken to the laboratory for testing, which makes the entire water quality testing process quite lengthy and time-consuming. At the same time, the water samples need to meet special requirements such as being free of sediment and being clear, making the operation cumbersome, labor-intensive, and inefficient.

[0004] Therefore, it is necessary to provide a drone-based water quality testing device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a water quality testing device for unmanned aerial vehicles (UAVs) to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] Furthermore, a connecting seat is provided at the bottom of the sedimentation cylinder, and an outer cylinder is provided on the connecting seat. The outer wall of the outer cylinder is provided with multiple water outlets and water inlets.

[0016] The inner cylinder is rotatably connected to the inner wall of the outer cylinder. A rotating pipe is provided in the middle of the inner cylinder, and the lower end of the rotating pipe is rotatably connected to the water inlet pipe.

[0017] Furthermore, the drainage unit includes:

[0018] A drain plate is provided on the top inner wall of the outer cylinder, the drain plate has a drain hole, and the bottom of the drain plate is provided with a positioning tube that is rotatably connected to the top of the rotating tube.

[0019] A top cover is located on the top of the outer cylinder. A top hole is provided at the upper end of the top cover. A hard plug is slidably connected to the inner wall of the top cover. A drain pipe is provided on the top wall of the top cover, which slides through the hard plug. A drain hole is provided on the drain pipe.

[0020] Furthermore, a triangular frame is provided at the upper end of the top cover, and a rocker arm is rotatably connected to the triangular frame. One end of the rocker arm is sealed and adapted to the top hole, and a sleeve is provided at the other end of the rocker arm. A float ball is installed at the bottom of the sleeve.

[0021] The outer wall of the outer cylinder is provided with an elastic insert rod, which passes through the float and is inserted into the sleeve.

[0022] Furthermore, the water filtration unit includes:

[0023] Multiple connecting ports are provided on the outer wall of the inner cylinder and are adapted to the water inlet;

[0024] A filter block is disposed on the inner wall of the outer cylinder, the rotating tube rotates through the filter block, and a first through hole is provided at the bottom of the connecting seat;

[0025] A drive component, located on the connecting seat, is used to drive the rotating tube to rotate.

[0026] Furthermore, the driving component includes:

[0027] A driven wheel is disposed on the rotating tube and located inside the connecting seat, and a second through hole is provided on the driven wheel;

[0028] The driving wheel is rotatably disposed on the inner wall of the connecting seat and meshes with the driven wheel. The bottom of the connecting seat is provided with a first driving member connected to the driving wheel.

[0029] Furthermore, the injection unit includes:

[0030] A buffer chamber is formed in the bottom wall of the liquid storage cylinder. A turbine is rotatably connected to the inner wall of the buffer chamber. A second driving component is provided at the bottom of the liquid storage cylinder and is driven by the turbine.

[0031] Multiple injection tubes, one end of which is connected to the buffer cavity.

[0032] Furthermore, the monitoring unit includes:

[0034] A liquid injection assembly, located on the light-transmitting cylinder, is used to inject the drug solution into the colorimetric cylinder.

[0035] Furthermore, the liquid dispensing assembly includes:

[0036] The pure water cylinder, the potassium sodium tartrate solution cylinder, and the Nessler's reagent cylinder are all mounted on the light-transmitting cylinder. The bottom of each of the pure water cylinder, the potassium sodium tartrate solution cylinder, and the Nessler's reagent cylinder is provided with multiple injection tubes that are connected to the inner end of each of the colorimetric cylinders.

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] This solution utilizes a drone to move the water quality testing device to the area to be tested. The pumping unit then extracts the water, which flows through a drainage unit into a sedimentation tank. Once the sedimentation tank reaches a designated volume, the pumping unit stops extracting water. After a period of settling, the water in the sedimentation tank is filtered by a filtration unit. The filtered water then flows into a storage tank. Next, an injection unit pumps the clear, sediment-free water from the storage tank into a monitoring unit, which then monitors the water, allowing for initial water quality assessment. This device can quickly determine the ammonia nitrogen content in the water sample, thus enabling a judgment on whether the ammonia nitrogen content exceeds the standard. This avoids the current situation where samples must be transported back to the laboratory for testing, reducing reliance on laboratories and allowing for rapid water quality assessment, especially when testing multiple water areas, saving significant time. Furthermore, the final water sample tested is treated, sediment-free, and clear. The device is simple to operate and requires minimal labor, significantly improving water quality testing efficiency and solving the problems of low efficiency and poor adaptability of traditional methods. It has high practicality and good performance.

[0039] Furthermore, the drone can move this water quality testing device to various complex water areas, allowing for the selection of sampling and testing locations as needed, and enabling multiple comparisons to improve the accuracy of water sample testing. It also overcomes the limitations of manual sampling locations, reduces the difficulty of manual sampling, and improves safety. Attached Figure Description

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figure 1-14 A water quality testing device for unmanned aerial vehicles (UAVs) includes a UAV body 1, and further includes:

[0058] A sedimentation cylinder 2 is mounted on the body 1 of the drone. A liquid storage cylinder 3 is connected to the bottom of the sedimentation cylinder 2. A pumping unit 4 for extracting the water to be tested is provided on the liquid storage cylinder 3.

[0059] Both the drainage unit 5 and the water filtration unit 6 are located inside the sedimentation tank 2. The drainage unit 5 is used to allow water drawn by the pumping unit 4 to enter the sedimentation tank 2 in a measured amount. The water filtration unit 6 is used to filter the settled water and pass it into the storage tank 3.

[0060] Monitoring unit 7 is installed on the body of the UAV 1 and is used to monitor the water to be tested;

[0061] The injection unit 8 is located on the liquid storage cylinder 3 and is used to pump water from the liquid storage cylinder 3 into the monitoring unit 7.

[0062] In use, the drone body 1 moves the water quality testing device to the area to be tested, bringing the pumping unit 4 into contact with the water. The pumping unit 4 then draws out the water, which flows through the drainage unit 5 into the sedimentation tank 2. Once the water level in the sedimentation tank 2 reaches a specified capacity, the pumping unit 4 stops drawing water. After the water in the sedimentation tank 2 has been left to stand for a period of time, some impurities will settle at the bottom. The settled water is then filtered by the filtration unit 6, and the filtered water is then passed into the storage tank 3, where it is stored. Then, the clear, sediment-free water in the storage cylinder 3 is pumped into the monitoring unit 7 through the injection unit 8. The monitoring unit 7 can then monitor the water body, thereby preliminarily determining the ammonia nitrogen content in the water body to be tested. This allows for a determination of whether the ammonia nitrogen content in the tested water body exceeds the standard, avoiding the current situation where samples must be transported back to the laboratory for testing. This reduces dependence on the laboratory and allows for rapid assessment of the water body, especially when testing multiple water bodies, saving a significant amount of time. At the same time, the water body ultimately tested by this device is also treated, sediment-free, and clear water. The operation is simple and labor-intensive, significantly improving the efficiency of water body testing. It solves the problems of low efficiency and poor adaptability of traditional methods, has high practicality, and good results.

[0063] Meanwhile, if a complex water sample is encountered, the drone can be used to quickly transport the sample to the laboratory for precise testing, thus balancing testing efficiency and accuracy.

[0064] Furthermore, the drone body 1 can move this water quality testing device to various complex water areas to be tested, allowing for selection of sampling and testing locations as needed, and enabling multiple comparisons to improve the accuracy of water sample testing. It also overcomes the limitations of manual sampling locations, reduces the difficulty of manual sampling, and improves safety.

[0065] A float plate is installed at the bottom of the rotor of the UAV body 1. This device can float on the water surface through the float plate, which improves the stability of the device during detection, thereby reducing the strength and accuracy requirements of the UAV body 1 and effectively preventing the UAV body 1 from falling into the water and malfunctioning.

[0066] For preferred options, please refer to [link / reference]. Figure 1-3 The drone body 1 is equipped with multiple chemical tanks 20, each with a first valve 21. The output end of the first valve 21 is connected to the interior of the sedimentation tank 2. The multiple chemical tanks 20 contain zinc sulfate solution and sodium hydroxide solution respectively. In this design, the first valve 21 can be a spider micro-valve.

[0067] With this design, when the water entering the sedimentation tank 2 is allowed to settle, the zinc sulfate solution and sodium hydroxide solution in the multiple chemical tanks 20 will enter the sedimentation tank 2 and react with the water therein by opening the first valve 21. This will produce zinc hydroxide precipitate, which will eventually settle at the bottom of the sedimentation tank 2, preventing it from entering the storage tank 3 and affecting the test results. Furthermore, this design makes the water in the sedimentation tank 2 alkaline, which is convenient for subsequent testing.

[0068] For preferred options, please refer to [link / reference]. Figure 1-5 Pumping unit 4 includes:

[0069] The water inlet cylinder 41 is located at the bottom of the liquid storage cylinder 3. An impeller pump 42 is installed at the bottom of the water inlet cylinder 41, and the output end of the impeller pump 42 is located inside the water inlet cylinder 41.

[0070] The water inlet pipe 43 is rotatably mounted on the bottom wall of the liquid storage cylinder 3, and the lower end of the water inlet pipe 43 extends into the water inlet cylinder 41.

[0071] Specifically, after the output end of the impeller pump 42 comes into contact with the water body to be tested, the impeller pump 42 starts and draws the water body into the inlet cylinder 41. Then the water body in the inlet cylinder 41 enters the inlet pipe 43, thus realizing the extraction of water body from the water body to be tested.

[0072] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 6-13The bottom of the sedimentation cylinder 2 is provided with a connecting seat 9, and an outer cylinder 10 is provided on the connecting seat 9. The outer wall of the outer cylinder 10 is provided with multiple water outlets 11 and water inlets 12.

[0073] The inner cylinder 13 is rotatably connected to the inner wall of the outer cylinder 10. A rotating pipe 14 is provided in the middle of the inner cylinder 13, and the lower end of the rotating pipe 14 is rotatably connected to the water inlet pipe 43.

[0074] Specifically, after the impeller pump 42 draws water into the inlet cylinder 41, the water will enter the rotary pipe 14 through the inlet pipe 43. Then, the water will fall into the outer cylinder 10 after passing through the drainage unit 5 and will be located above the top of the inner cylinder 13. Then, the water will be discharged into the sedimentation cylinder 2 through the outlet 11 of the outer cylinder 10. When the water in the sedimentation cylinder 2 reaches the specified height, the drainage unit 5 will stop discharging water, and the impeller pump 42 will also stop working, thus realizing the function of introducing a certain amount of water into the sedimentation cylinder 2.

[0075] For preferred options, please refer to [link / reference]. Figure 8-13 The outer wall of the inner cylinder 13 is provided with two sealing rings 25. The inner cylinder 13 is rotatably connected to the inner wall of the outer cylinder 10 through the sealing rings 25 and is in sealed contact. The two sealing rings 25 are located at both ends of the connecting port 61. The sealing rings 25 can effectively prevent water at the top of the outer cylinder 10 from directly entering the inner cylinder 13, that is, prevent unprecipitated and unfiltered liquid from passing through the inner cylinder 13 and then entering the liquid storage cylinder 3, thus affecting the experimental results.

[0076] For preferred options, please refer to [link / reference]. Figure 6-13 The drainage unit 5 includes:

[0077] The drain plate 51 is located on the top inner wall of the outer cylinder 10. The drain plate 51 has a drain hole and the bottom of the drain plate 51 is provided with a positioning tube 52 that is rotatably connected to the top of the rotating tube 14.

[0078] The top cover 53 is located on the top of the outer cylinder 10. The top end of the top cover 53 has a top hole 54. The inner wall of the top cover 53 is slidably connected to a hard plug 55. The top wall of the top cover 53 is provided with a drain pipe 56 that slides through the hard plug 55. The drain pipe 56 has a drain hole 57.

[0079] Specifically, under the action of the impeller pump 42, the water passing through the inlet pipe 43 and the rotating pipe 14 will enter the positioning pipe 52. The water in the positioning pipe 52 will then flow out through the drain hole 57 on the drain pipe 56. That is, the water will enter the top cover 53 and be located above the hard plug 55. At this time, when the top cover 53 is filled with water, the water will flow out from the top hole 54 of the top cover 53 into the sedimentation cylinder 2. Since the liquid flow rate in the positioning tube 52 is much greater than that in the top hole 54, the pressure in the positioning tube 52 gradually increases. When the pressure in the positioning tube 52 is higher than that in the top cover 53, the water in the positioning tube 52 will push up the hard plug 55, causing the hard plug 55 to move upward and expose the drain plate 51. Then, the water in the positioning tube 52 will flow through the drain hole of the drain plate 51 to the top of the outer cylinder 10 and be discharged into the sedimentation cylinder 2 through the outlet 11 of the outer cylinder 10. As a result, the water level in the sedimentation cylinder 2 gradually increases. When it rises to the designated position, no more water is discharged into the sedimentation cylinder 2, and the impeller pump 42 also stops working, thus completing the process of extracting the liquid to be tested into the sedimentation cylinder 2.

[0080] Furthermore, the hard plug 55 is surrounded by a soft skin, and the middle part of the hard plug 55 can move up and down through the soft skin. The hard plug 55 is connected to the inner wall of the top cover 53 through the soft skin. When the hard plug 55 is impacted, the soft skin can deform, thereby causing the hard plug 55 to move up and down along the inner wall of the top cover 53.

[0081] For preferred options, please refer to [link / reference]. Figure 4 and Figure 6-7 The top cover 53 is provided with a tripod 15, and a rocker 16 is rotatably connected to the tripod 15. One end of the rocker 16 is sealed and adapted to the top hole 54, and the other end of the rocker 16 is provided with a sleeve 17. A float ball 18 is installed at the bottom of the sleeve 17.

[0082] The outer wall of the outer cylinder 10 is provided with an elastic rod 19. The elastic rod 19 passes through the float 18 and is inserted into the sleeve 17. The float 18 can swing along the elastic rod 19. The inner diameter of the sleeve 17 is much larger than the outer diameter of the elastic rod 19, that is, the gap between the elastic rod 19 and the sleeve 17 is large.

[0083] As explained above, with this design, the water to be tested is discharged from the outlet 11 of the outer cylinder 10 into the sedimentation tank 2. As the water level in the sedimentation tank 2 rises and comes into contact with the float 18, the increased water level causes the float 18 and the sleeve 17 to move upwards and deflect at an angle. This means the sleeve 17 pushes the rocker arm 16 upwards, causing the other end of the rocker arm 16 to press down and block the top hole 54 on the top cover 53, preventing water from flowing out of the top cover 53. Therefore, the pressure inside the top cover 53 gradually increases. When the pressure inside the top cover 53 exceeds the pressure inside the positioning tube 52, the rigid plug 55 moves downwards to reset and blocks the leak hole of the drain plate 51. At this point, water can no longer enter the outer cylinder 10, and no more water flows out of the outlet 11. Simultaneously, the impeller pump 42 stops working. This achieves the goal of stopping water intake once the liquid level in the sedimentation tank 2 reaches the specified level, resulting in good automation.

[0084] As can be seen from the above, a closed-loop control logic that does not require electrical control is formed by the pressure difference between the positioning tube 52 and the top cover 53, the up and down movement of the hard plug 55, and the mechanical linkage between the float 18 and the rocker 16. This mechanical linkage reduces the use of electronic components, avoids interference in water quality detection (such as short circuits and signal failures), and improves reliability.

[0085] More importantly, the core function of the sedimentation tank 2 is to precipitate impurities and generate zinc hydroxide precipitate. The clear water in the middle needs to be extracted for subsequent testing. The aforementioned drainage unit 5 and other structures allow water to enter the sedimentation tank 2 slowly and quantitatively, ensuring that impurities are fully precipitated. If water is directly introduced into the sedimentation tank 2 through the impeller pump 42, the flow rate may be too fast, resulting in insufficient sedimentation. This would cause the impurities that have already settled at the bottom of the sedimentation tank 2 to rise to the surface, reducing the quality of the sedimentation. At the same time, the design of the liquid flow rate of the positioning tube 52 being much greater than that of the top hole 54 can also buffer the liquid flow rate and avoid the impact of excessive instantaneous flow on the sedimentation environment inside the sedimentation tank 2, thus preventing the impact on the accuracy of subsequent testing.

[0086] Furthermore, the reset mechanism of the hard plug 55 can immediately block the discharge of liquid after the liquid level reaches the target, preventing overflow. Sensor-type electronic components may have delay problems when shutting down (such as signal transmission lag), which cannot achieve the effect of this structure. It can also reduce energy consumption, lower costs, and improve reliability.

[0087] In this embodiment, preferably, please refer to [reference needed]. Figure 6-13 The water filtration unit 6 includes:

[0088] Multiple connecting ports 61 are provided on the outer wall of the inner cylinder 13 and are adapted to the water inlet 12;

[0089] The filter block 62 is located on the inner wall of the outer cylinder 10. The rotating tube 14 rotates through the filter block 62. The bottom of the connecting seat 9 is provided with a first through hole 63.

[0090] The drive assembly 64 is located on the connector 9 and is used to drive the rotating tube 14 to rotate.

[0091] Specifically, during the water intake and subsequent sedimentation process of the sedimentation tank 2, the connecting port 61 of the inner cylinder 13 is always offset from the water inlet 12 of the outer cylinder 10, that is, the connecting port 61 and the water inlet 12 are not connected.

[0092] After the water in the sedimentation tank 2 has settled, the drive assembly 64 drives the rotating tube 14 to rotate, which in turn drives the inner cylinder 13 to rotate. The inner cylinder 13 then drives the connecting port 61 on its outer wall to rotate, so that the connecting port 61 is rotated to the position of the water inlet 12, thus connecting the water inlet 12 and the connecting port 61. At this time, the clear water in the middle of the sedimentation tank 2 will enter the inner cylinder 13 through the water inlet 12 and the connecting port 61, and then be filtered by the filter block 62 before entering the connecting seat 9. Finally, it will pass through the first through hole 63 and enter the storage tank 3 for storing the clear liquid to be tested.

[0093] In this embodiment, preferably, please refer to [reference needed]. Figure 6 and Figure 8-9 The driver component 64 includes:

[0094] Driven wheel 641 is provided on rotating tube 14 and located in connecting seat 9. A second through hole 644 is provided on driven wheel 641.

[0095] The driving wheel 642 is rotatably mounted on the inner wall of the connecting seat 9 and meshes with the driven wheel 641. The bottom of the connecting seat 9 is provided with a first driving member 643 connected to the driving wheel 642.

[0096] Specifically, the first driving component 643 in this solution can be a servo motor, which drives the driving wheel 642 to rotate, and the driving wheel 642 in turn drives the driven wheel 641 and the rotating tube 14 to rotate. In addition, the water filtered by the filter block 62 will pass through the second through hole 644 and the first through hole 63 into the liquid storage cylinder 3.

[0097] In this embodiment, preferably, please refer to [reference needed]. Figure 1-5 The injection unit 8 includes:

[0098] A buffer chamber 81 is opened on the bottom wall of the liquid storage cylinder 3. A turbine 82 is rotatably connected to the inner wall of the buffer chamber 81. A second driving component 83 is provided at the bottom of the liquid storage cylinder 3 and is driven by the turbine 82.

[0099] Multiple injection tubes 84, one end of which is connected to the buffer cavity 81.

[0100] Specifically, the second driving component 83 in this solution can be a servo motor. The second driving component 83 can drive the turbine 82 to rotate. The rotation of the turbine 82 can draw water from the storage cylinder 3 into the buffer chamber 81, which can store the water to be tested. Furthermore, the rotation of the turbine 82 will create a certain pressure in the buffer chamber 81. Under the action of pressure, the water in the buffer chamber 81 will enter the injection pipe 84 and finally be introduced into the monitoring unit 7 for detection.

[0101] In this embodiment, preferably, please refer to [reference needed]. Figure 1-3 and Figure 14 Monitoring unit 7 includes:

[0102] The light-transmitting tube 71 has a camera 72 installed on its inner bottom wall. The outer wall of the light-transmitting tube 71 is provided with multiple colorimetric tubes 73. The outer end of the colorimetric tube 73 is connected to the injection tube 84. The outer end of the colorimetric tube 73 is equipped with a second valve 22 connected to the injection tube 84. The second valve 22 can be a spider micro valve. The light-transmitting tube 71 facilitates the camera 72 to take pictures.

[0103] The liquid addition assembly 74 is located on the light-transmitting tube 71 and is used to inject the drug solution into the colorimetric tube 73.

[0104] Specifically, after opening the second valve 22, the water from the injection tube 84 will enter the colorimetric cylinder 73, resulting in different volumes of the water to be tested entering multiple colorimetric cylinders 73. For example, seven sets of colorimetric cylinders 73 (each with a volume of 50ml standard colorimetric cylinders) can be set for comparison and detection, so that the volumes of the water to be tested entering the seven sets of colorimetric cylinders 73 are 0mL, 0.50mL, 1.00mL, 3.00mL, 5.00mL, 7.00mL, and 10.0mL. That is, for different target volumes, the inflow rate is adjusted by controlling the closing time of the corresponding second valve 22, such as:

[0105] A 0mL colorimetric cylinder is required, and the second valve 22 should always be closed;

[0106] A 0.50 mL cuvette is required, and the second valve 22 has the shortest opening time;

[0107] A 10.0 mL cuvette is required, and the second valve 22 has the longest opening time;

[0108] The volume of the water to be tested in each colorimetric cylinder 73 can be controlled according to the above rules. After the liquid is added, the reagent is injected into each colorimetric cylinder 73 through the liquid addition component 74. After the water surface is shaken with the drone body 1, the color of the liquid in the seven sets of colorimetric cylinders 73 is photographed by the camera 72, thereby roughly determining the ammonia nitrogen content in the water. This allows for quick and convenient detection of the ammonia nitrogen content in the water. Furthermore, the number of colorimetric cylinders 73 can be selected according to specific needs, offering high flexibility.

[0109] When the ammonia nitrogen content in the water cannot be determined by color, the drone body 1 can be driven to transport the liquid to be tested in the colorimetric cylinder 73 back. After that, the ammonia nitrogen content in the water can be accurately calculated through experiments, balancing efficiency and accuracy.

[0110] In this embodiment, preferably, please refer to [reference needed]. Figure 14 The liquid addition assembly 74 includes:

[0111] Pure water cylinder 741, potassium sodium tartrate solution cylinder 742, and Nessler's reagent cylinder 743 are all mounted on light-transmitting cylinder 71. The bottom of pure water cylinder 741, potassium sodium tartrate solution cylinder 742, and Nessler's reagent cylinder 743 are provided with multiple injection tubes 744 that are connected to the inner end of each colorimetric cylinder 73. A third valve 23 is installed on the injection tube 744.

[0112] Specifically, after injecting the corresponding volume of the liquid to be tested into the colorimetric cylinder 73, the third valve 23 of each injection tube 744 is opened, so that pure water is added to each group of colorimetric cylinders 73 through the pure water cylinder 741 up to the mark. Then, 1.0 mL of potassium tartrate is added to each group of colorimetric cylinders 73 through the potassium sodium tartrate solution cylinder 742, and 1.5 mL of Nessler's reagent is added to each group of colorimetric cylinders 73 through the Nessler's reagent cylinder 743. After shaking the water surface with the drone body 1, the color of the liquid in each group of colorimetric cylinders 73 is photographed through the camera 72, so as to roughly determine the ammonia nitrogen content in the water body to be tested.

[0113] Both the sedimentation tank 2 and the liquid storage tank 3 are equipped with drain valves 24 on their outer walls. After the test is completed, the waste liquid and impurities in the sedimentation tank 2 and the liquid storage tank 3 can be discharged through the drain valves 24.

[0114] The main working steps of this invention are as follows:

[0115] S1: The device is transported to the water area to be tested by the drone body 1, so that the impeller pump 42 comes into contact with the water body. Driving the impeller pump 42 can suck the water body to be tested into the water inlet 41. The water body to be tested in the water inlet 41 can be introduced into the rotating pipe 14 through the water inlet pipe 43.

[0116] S2: The water to be tested in the rotating pipe 14 enters the drain 56 through the positioning pipe 52, and then flows into the top cover 53 through the drain hole 57. When the top cover 53 is full of the liquid to be tested, the liquid can be discharged from the top hole 54. Since the liquid flow rate in the positioning pipe 52 is much greater than the liquid flow rate in the top hole 54, the pressure in the positioning pipe 52 gradually increases. When the pressure in the positioning pipe 52 is higher than the pressure in the top cover 53, the liquid in the positioning pipe 52 will push up the hard plug 55, thereby exposing the drain plate 51. At this time, the water in the positioning pipe 52 can flow into the top of the outer cylinder 10 through the drain hole of the drain plate 51, and then flow into the sedimentation cylinder 2 through the outlet 11.

[0117] S3: As the liquid level in the sedimentation tank 2 gradually rises, when the liquid level comes into contact with the float ball 18, it will drive the float ball 18 to rise and push the seesaw 16 upward through the sleeve 17, so that the other end of the seesaw 16 blocks the top hole 54, preventing the water in the top cover 53 from flowing out, and the pressure in the top cover 53 increases. When the pressure in the top cover 53 is greater than the pressure in the positioning tube 52, the hard plug 55 resets and blocks the leak plate 51. At this time, the water cannot enter the outer cylinder 10, and the impeller pump 42 stops working.

[0118] S4: After the sedimentation tank 2 has been left to stand for a period of time, the zinc sulfate solution and sodium hydroxide solution in the two sets of chemical tanks 20 are introduced into the sedimentation tank 2, making the water to be tested in the sedimentation tank 2 alkaline and generating zinc hydroxide precipitate. After that, the first driving component 643 drives the driving wheel 642 to rotate. The driving wheel 642 drives the driven wheel 641 and the rotating tube 14 to rotate. The rotating tube 14 drives the inner cylinder 13 to rotate, so that the connecting port 61 on the side wall of the inner cylinder 13 coincides with the water inlet 12 and connects. At this time, the clear liquid in the middle of the sedimentation tank 2 can enter the inner cylinder 13 through the water inlet 12 and the connecting port 61. After being filtered by the filter block 62, it passes through the second through hole 644 and the first through hole 63 in sequence and enters the liquid storage tank 3.

[0119] S5: Drive the second drive unit 83 to drive the turbine 82 to rotate, thereby drawing the water to be tested from the storage cylinder 3 into the buffer chamber 81. Finally, the water in the buffer chamber 81 is sent into each set of colorimetric cylinders 73 through the injection pipe, so that the volume of the liquid to be tested in each set of colorimetric cylinders 73 is different. Pure water is added to the colorimetric cylinder 73 to the mark through the pure water cylinder 741. Then, 1.0 mL of potassium sodium tartrate solution and 1.5 mL of Nessler's reagent are added to each set of colorimetric cylinders 73 through the potassium sodium tartrate solution cylinder 742 and the Nessler's reagent cylinder 743. After the water surface is shaken with the drone body 1, the color of the liquid in each set of colorimetric cylinders 73 is photographed through the camera 72, thereby roughly determining the ammonia nitrogen content in the water to be tested.
