[0002] As key measures for pollution source control and water pollution control, water sampling and water quality monitoring play an irreplaceable role in maintaining the ecological environment of major rivers in my country, such as the Yangtze River, the Yellow River, and the Jialing River. Given that the sources of major rivers in my country are mostly located in plateaus or mountainous areas, with complex terrain and sparse population, it is difficult for traditional online monitoring stations to achieve comprehensive coverage. For this reason, the use of drones equipped with sampling equipment has become an effective way to improve sampling efficiency and coverage.

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] Embodiment 1, this embodiment provides a mobile water quality sampling system for plateau or mountainous areas, such as Figure 1-Figure 5 As shown, it includes a remote terminal 1, a flying carrier 2 and a sampling device 3, wherein the remote terminal 1 is used to construct a sampling route according to the characteristic data of each sampling point; wherein the characteristic data includes the location of the sampling point and the water flow velocity of the sampling point; the water flow velocity of each sampling point on the sampling route increases in sequence; the remote terminal 1 is also used to generate flight instructions and sampling instructions; the flying carrier 2 is wirelessly connected to the remote terminal 1, and after the flying carrier 2 obtains the flight instruction, it moves along the sampling route; the sampling device 3 includes a sample compartment 30, a sampling unit 31, and a sample bottle 32 and a control module 33, the sample bin 30 is arranged on the flying carrier 2; a plurality of sample bottles 32 are arranged on the sample bin 30; the sampling unit 31 is arranged in the sample bin 30, and the sampling unit 31 is connected with the sample bottles 32; the control module 33 is arranged on the top of the sample bin 30, and the control module 33 is connected with the sampling unit 31 and the remote terminal 1; wherein, after the control module 33 obtains the sampling instruction, it controls the sampling unit 31 to transport the water samples of each sampling point on the sampling route to each sample bottle 32 in turn.

[0033] Exemplarily, during the implementation process, when sampling the target water area, the number of sampling points in the target water area is first determined, and the characteristic data of each sampling point in the target water area is obtained from historical data or actual measurements. Among them, the characteristic data of the sampling point includes the location of the sampling point and the water flow velocity in the sampling point. The water flow velocity is related to the terrain environment of the sampling point, the depth of the sampling location, etc. After obtaining the location of each sampling point and the water flow velocity in each sampling point, the remote terminal 1 connects each sampling point in sequence in the order of water flow velocity from small to large based on the location of each sampling point and the water flow velocity in each sampling point to form a sampling route. At the same time, the remote terminal 1 generates flight instructions and sampling instructions.

[0034] The flying vehicle 2 is wirelessly connected to the remote terminal 1. The flying vehicle 2 can receive flight instructions from the remote terminal 1 and fly autonomously along a preset sampling route after receiving the flight instructions.

[0035] The sampling device 3 includes a sample chamber 30, a sampling unit 31, a sample bottle 32 and a control module 33. The sample chamber 30 is installed on the flying carrier 2 by screwing, clamping, clamping, etc., and the sample chamber has a heat preservation and refrigeration function.

[0036] The number of sample bottles 32 can be set according to the number of sampling points, in order to reduce the risk of the flying carrier 2 carrying too many sample bottles 32 and increasing the flight load of the flying carrier 2. The sample bottles 32 can be detachably connected to the sample bin 30 by clamping, snapping, etc., so that the staff can adjust the number of sample bottles 32 according to the number of sampling points.

[0037] The sampling unit 31 is connected to the sample chamber 30 by welding, screwing, etc. The liquid outlet of the sampling unit 31 is connected to each sample bottle 32 to achieve the purpose of extracting water samples from different sampling points and transporting the water samples to the corresponding sample bottles 32 for storage.

[0038] The control module 33 is connected to the sample chamber 30 by screwing, clamping, etc. The control module 33 is wirelessly connected to the remote terminal 1, and the control module 33 can receive sampling instructions from the remote terminal 1. The control module 33 is connected to the sampling unit 31, and after the control module 33 receives the sampling instruction from the remote terminal 1, the control module 33 generates a sampling signal. The sampling unit 31 obtains the sampling signal to extract water samples in the sampling point.

[0039] When in use, when the remote terminal 1 receives a demand for sampling the target water area, the remote terminal 1 sends a flight instruction to the flight carrier 2. After receiving the flight instruction, the flight carrier 2 flies to the first sampling point in the target water area according to the sampling route. After the flight carrier 2 flies to the first sampling point, the remote terminal 1 sends a sampling instruction to the control module 33. The control module 33 generates a sampling signal after receiving the sampling instruction. At this time, the sampling unit 31 responds to the sampling signal and transports the water sample in the first sampling point to the first sample bottle 32.

[0040] After sampling at the first sampling point is completed, the flying carrier 2 flies to the second sampling point of the target water area according to the sampling route. After the flying carrier 2 flies to the second sampling point, the remote terminal 1 sends a sampling instruction to the control module 33, and the control module 33 generates a sampling signal upon receiving the sampling instruction. At this time, the sampling unit 31 responds to the sampling signal and transfers the water sample in the second sampling point to the second sample bottle 32. This cycle is repeated until all sampling points in the target water area are sampled.

[0041] On the one hand, as the number of completed samples at the sampling point increases, the water flow velocity in the sampling point increases. At the same time, the number of sample bottles 32 carrying water samples increases, which increases the weight of the sampling device 3 itself. It is expected to increase the weight of the sampling device 3, thereby reducing the impact of the increase in water flow velocity on the water flow impact of the flying carrier 2, thereby reducing the risk of tilting of the flying carrier 2, improving the stability and maneuverability of the flying carrier 2, reducing the sampling depth measurement deviation, and improving the accuracy and reliability of the sample data. On the other hand, the flying carrier 2 can quickly reach the target waters, is not restricted by ground traffic conditions, and greatly improves the sampling speed and efficiency. On the other hand, sampling of multiple sampling points can be achieved, thereby achieving the purpose of improving sampling efficiency.

[0042] Embodiment 2, based on the above embodiment 1, in this embodiment, the process of the remote terminal 1 constructing the sampling route includes: constructing a position distribution map of each sampling point based on the position of each sampling point; constructing a sequence set in which the water flow speed is arranged from small to large based on the water flow speed of each sampling point; judging whether there are sampling points with the same water flow speed in the sequence set; if there are no sampling points with the same water flow speed in the sequence set, connecting the sampling points in the position distribution map in order from small to large water flow speed to obtain the sampling route; if there are sampling points with the same water flow speed in the sequence set, the sampling points in the position distribution map are connected in order from small to large water flow speed to obtain the sampling route; For the same sampling points, the sampling points with the same water flow speed in the sequence set are recorded as same-speed sampling points, and the sampling points with different water flow speeds are recorded as different-speed sampling points; based on the positions of the same-speed sampling points and the positions of the different-speed sampling points adjacent to the same-speed sampling points, the shortest travel route between the same-speed sampling points and the different-speed sampling points adjacent to the same-speed sampling points is constructed; the moving speed sampling points in the position distribution map are connected in order from small to large water flow speed, and the same-speed sampling points in the position distribution map and the different-speed sampling points adjacent to the same-speed sampling points are connected according to the shortest travel route to obtain the sampling route.

[0043] Exemplarily, during the implementation process, the remote terminal 1 first constructs a location distribution map based on the location information of each sampling point in the target water area to clarify the spatial relationship between each sampling point.

[0044] Secondly, based on the water flow velocity of each sampling point, a sequence set is constructed, which is arranged from small to large water flow velocity, and it is determined whether there are sampling points with the same water flow velocity in the sequence set.

[0045] If there are no sampling points with the same water flow velocity in the sequence set, the sampling points are directly connected in the order of water flow velocity from small to large to form a sampling route.

[0046] If there are sampling points with the same water flow velocity in the sequence set, the sampling points with the same water flow velocity are marked as the same-speed sampling points, and the sampling points with different water flow velocities are marked as different-speed sampling points. For each same-speed sampling point, find the adjacent different-speed sampling point (i.e., the nearest sampling point with different water flow velocities). First, based on the positions of the same-speed sampling points and the adjacent different-speed sampling points, construct the shortest route. In order to ensure that the flight carrier 2 can reach the next sampling point by the shortest path when processing the same-speed sampling points, thereby saving time and energy. Secondly, in the order of water flow velocity from small to large, the different-speed sampling points in the position distribution map are connected in sequence, and in the process of connecting the different-speed sampling points, the same-speed sampling points and the adjacent different-speed sampling points are connected according to the shortest route to finally form a complete sampling route. On the one hand, by constructing a position distribution map and a water flow velocity sequence set, in order to ensure the scientificity and rationality of the sampling route. On the other hand, when processing sampling points with the same water flow velocity, by constructing the shortest route, it is hoped to reduce unnecessary detours and repeated paths, thereby reducing the flight distance of the flying vehicle 2 in the air, so as to improve the flight efficiency of the flying vehicle 2 and reduce the energy consumption of the flying vehicle 2.

[0047] For example, there are five sampling points in the target area, which are recorded as J1, J2, J3, J4 and J5, and the water flow velocities at the five sampling points are Q1, Q2, Q3, Q4 and Q5. If Q1<Q3<Q4<Q2<Q5, the constructed sequence set is recorded as {(J1, Q1), (J3, Q3), (J4, Q4, (J2, Q2), (J5, Q5)}. And the order of the sampling points on the sampling route is J1, J3, J4, J2 and J5.

[0048] If Q1<Q2=Q3<Q4<Q5, the constructed sequence set is recorded as {(J1,Q1)、(J2,Q2)、(J3,Q3)、(J4,Q4)、(J5,Q5)}. Among them, J2 and J3 are the same speed collection points, and J1, J4 and J5 are different speed collection points. Calculate the shortest route between J1, J2, J3 and J4, and connect J5 after J4.

[0049] Embodiment 3, based on the above embodiment 1, in this embodiment, as Figure 3As shown, the sampling unit 31 includes a first driving motor 311, a tube winding wheel 312, a sampling hose 313 and a sampling pump 314; the first driving motor 311 is arranged on the sample chamber 30, and the first driving motor 311 is connected to the control module 33; the tube winding wheel 312 is arranged on the output shaft of the first driving motor 311; the sampling hose 313 is wound on the tube winding wheel 312, and the sampling hose 313 is connected to the sample bottle 32; the sampling pump 314 is arranged at one end of the sampling hose 313 away from the sample bottle 32, and the sampling pump 314 is connected to the control module 33.

[0050] Exemplarily, during implementation, the sampling unit 31 includes a first driving motor 311 , a tube winding wheel 312 , a sampling hose 313 and a sampling pump 314 .

[0051] The first driving motor 311 is disposed on the sample chamber 30 by screwing, welding or the like, and the first driving motor 311 is connected to the control module 33 .

[0052] The tube winding wheel 312 is connected to the output shaft of the first driving motor 311 by welding, screwing or the like.

[0053] The sampling hose 313 is wound around the hose reel 312 , and one end of the sampling hose 313 is connected to the sample bottle 32 .

[0054] The sampling pump 314 is connected to one end of the sampling hose 313 away from the sample bottle 32, and a protective sleeve (screen) is provided outside the sampling pump 314 to reduce the risk of the sampling pump 314 touching the bottom and sucking in the bottom mud.

[0055] When in use, before the flight carrier 2 takes off, the sampling hose 313 is completely wound around the hose reel 312, and the sampling pump 314 is in a closed state. The flight carrier 2 flies to a predetermined sampling point according to the flight instruction of the remote terminal 1. After the control module 33 receives the sampling instruction of the remote terminal 1, the control module 33 controls the first drive motor 311 to rotate forward. At this time, under the action of the reel in the sampling pump 314, the sampling hose 313 gradually stretches until the sampling pump 314 drops to the target sampling position of the sampling point. Among them, a liquid level sensor can be set on the sampling pump 314 to detect the descending position of the sampling pump 314, so as to determine whether the sampling pump 314 reaches the target sampling position. After the sampling pump 314 drops to the target sampling position, the control module 33 controls the sampling pump 314 to operate to transport the water sample at the target position of the sampling point to the sample bottle 32. After the sampling pump 314 works for a preset time, the sampling is completed. At this time, the sample liquid in the sampling hose 313 and the sampling pump 314 will flow out with the sampling pump 314, and then the control module 33 controls the sampling pump 314 to stop working, and controls the first drive motor 311 to rotate in the opposite direction to rewind the sampling hose 313 on the pipe winding wheel 312. After the sampling hose 313 is wound, the flying carrier 2 goes to the next sampling point and repeats the above sampling process until all sampling points are sampled. On the one hand, the working time of the sampling pump 314 is accurately controlled by the control module 33, so as to ensure that the amount of water sampled each time is consistent, thereby improving the sampling accuracy and reliability. On the other hand, the expansion and contraction of the sampling hose 313 is controlled by the first drive motor 311 and the pipe winding wheel 312, so as to reduce the risk of turmoil or breakage of the sampling hose 313 due to the impact of water flow during the process of the flying carrier 2 going to the next sampling point, thereby achieving the purpose of system stability and safety. On the other hand, the length of the sampling hose 313 can be adjusted as needed, so as to achieve the purpose of enabling the system to adapt to different depth sampling requirements and thus expand the scope of application.

[0056] Among them, an optional implementation method is to set a detection module on the sampling pump 314, which is wirelessly connected to the remote terminal 1. The detection module can directly monitor the parameters in the water sample at the collection location that are easily affected by transportation, external environment, etc., such as water temperature, dissolved oxygen, turbidity, pH and conductivity.

[0057] Embodiment 4, based on the above embodiment 3, in this embodiment, as Figure 3 Combination Figure 5As shown, the sampling hose 313 includes a first pipe section 3131 and a second pipe section 3132; a flow channel 4 is arranged inside the pipe winding wheel 312; the two ends of the flow channel 4 are respectively connected to the first pipe section 3131 and the second pipe section 3132; wherein, the first pipe section 3131 is rotatably connected to the end of the pipe winding wheel 312 away from the first driving motor 311; the end of the first pipe section 3131 away from the flow channel 4 is connected to the sample bottle 32; the second pipe section 3132 is wound around the pipe winding wheel 312, and the end of the second pipe section 3132 away from the flow channel 4 is connected to the sampling pump 314.

[0058] Exemplarily, in the implementation process, a flow channel 4 is provided inside the bypass pipe. The sampling hose 313 includes a first pipe section 3131 and a second pipe section 3132 .

[0059] One end of the first tube section 3131 is connected to the sample bottle 32, and the other end of the first tube section 3131 is rotatably connected to the end of the tube winding wheel 312 away from the first driving motor 311 through a bearing seal, and the bearing is coaxial with the output shaft of the first driving motor 311, so that when the first driving motor 311 drives the tube winding wheel 312 to rotate, the first tube section 3131 can rotate freely, so as to reduce the risk of the first tube section 3131 being entangled or even broken when the tube winding wheel 312 rotates.

[0060] The first pipe section 3131 is connected to the flow channel 4 inside the pipe winding wheel 312. The second pipe section 3132 is wound around the pipe winding wheel 312, one end of the second pipe section 3132 is connected to the flow channel 4 inside the pipe winding wheel 312, and the other end of the second pipe section 3132 is connected to the sampling pump 314. The purpose of sampling the sample bottle 32 is achieved through the first pipe section 3131, the sampling pump 314, the second pipeline and the flow channel 4.

[0061] In Example 5, during use, each sampling point uses the same sampling unit 31, and the water sample of the previous sampling point may remain in the first pipe section 3131, the second pipe section 3132, the flow channel 4 and the sampling pump 314 of the sampling unit 31. Therefore, in order to reduce the risk of cross-infection of water samples between different sampling points. Based on the above Example 4, in this embodiment, Figure 3 As shown, the sampling unit 31 also includes a liquid outlet pipe 315; the liquid outlet pipe 315 and the first pipe section 3131 are both sealed and connected to the sample bottle 32; wherein, the liquid outlet pipe 315 is arranged at the pipe mouth of the sample bottle 32, and the first pipe section 3131 extends to the bottom of the sample bottle 32.

[0062] Exemplarily, during the implementation process, the sampling tube further includes a liquid outlet tube 315. The liquid outlet tube 315 and the first tube section 3131 are both inserted into the sample bottle 32, and the liquid outlet tube 315 and the sample bottle 32, as well as the first tube section 3131 and the sample bottle 32 are sealed. The liquid inlet of the liquid outlet tube 315 (the end of the liquid outlet tube 315 located in the sample bottle 32) is located at the mouth of the sample bottle 32, and the liquid outlet of the first tube section 3131 (the end of the first tube section 3131 away from the flow channel 4) is located at the bottom of the sample bottle 32.

[0063] During use, when the sampling pump 314 is working, the water sample in the sampling point enters the sample bottle 32 through the sampling pump 314, the second pipeline, the flow channel 4, and the first pipeline. After entering the sample bottle 32, the water sample gradually flows from the bottom of the sample bottle 32 to the mouth of the sample bottle 32. After the water sample fills the sample bottle 32, the water sample in the sample bottle 32 flows out of the sample bottle 32 from the liquid outlet pipe 315. As new water samples continue to flow into the bottom of the sample bottle 32, the water sample at the upper end of the sample bottle 32 is gradually discharged. It is expected to achieve the purpose of using the water sample in the sampling point to clean the sampling pump 314, the second pipeline, the flow channel 4, the first pipeline, the sample bottle 32 and the liquid outlet pipe 315, thereby reducing the risk of cross-infection of water samples between sampling points.

The driving unit 34 is connected to the control module 33, and the control module 33 drives the driving unit 34 to work, and the driving unit 34 drives the sample bottle 32 to rotate to the bottom of the first tube section 3131 and the liquid outlet pipe 315, and moves the sample bottle 32 upward, so that the lower ends of the first tube section 3131 and the liquid outlet pipe 315 can be inserted into the sample bottle 32. After the sample bottle 32 completes sampling, the driving unit 34 drives the sample bottle 32 to move downward to separate the sample bottle 32 from the first tube section 3131 and the liquid outlet pipe 315. After the sample bottle 32 is separated from the first tube section 3131 and the liquid outlet pipe 315, the driving unit 34 drives the sample bottle 32 to rotate, so that the next sample bottle 32 rotates to the direction of the first tube section 3131 and the liquid outlet pipe 315. The purpose is to transport water samples from different sampling points to different sample bottles 32 .

[0067] Embodiment 7, based on the above embodiment 6, in this embodiment, as Figure 4 As shown, the driving unit 34 includes a second driving motor 341, an electric telescopic rod 342 and a connecting plate 343; the second driving motor 341, the electric telescopic rod 342 and the connecting plate 343 are arranged in sequence along the direction from the lower end of the accommodating chamber 5 to the upper end of the accommodating chamber 5; the second driving motor 341 and the electric telescopic rod 342 are both connected to the control module 33; the electric telescopic rod 342 is arranged on the output shaft of the second driving motor 341; the connecting plate 343 is arranged on the electric telescopic rod 342; wherein, the sample bottle 32 is arranged on the connecting plate 343, the sample bottle 32 corresponds to the liquid outlet pipe 315 and the first pipe section 3131, and a plurality of the sample bottles 32 are evenly arranged around the output shaft of the second driving motor 341.

[0068] Exemplarily, in the implementation process, the driving unit 34 includes a second driving motor 341 , an electric telescopic rod 342 and a connecting plate 343 .

[0070] The electric telescopic rod 342 is connected to the output shaft of the second driving motor 341 by screwing, welding or the like, and the electric telescopic rod 342 is connected to the control module 33 .

[0071] The connecting plate 343 is connected to the upper end of the electric telescopic rod 342 by welding, screwing or the like.

[0073] During sampling, the control module 33 controls the second driving motor 341 to rotate so that the sample bottle 32 rotates to the position directly below the first pipe section 3131 and the liquid outlet pipe 315. When the sample bottle 32 rotates to the position directly below the first pipe section 3131 and the liquid outlet pipe 315, the control module 33 controls the electric telescopic rod 342 to extend so that the sample bottle 32 on the connecting plate 343 moves upward, thereby inserting the first pipe and the liquid outlet pipe 315 into the sample bottle 32. After the sample bottle 32 completes sampling, the control module 33 controls the electric telescopic rod 342 to retract so that the sample bottle 32 on the connecting plate 343 moves downward, thereby separating the sample bottle 32 from the first pipe section 3131 and the liquid outlet pipe 315. After the sample bottle 32 is separated from the first pipe section 3131 and the liquid outlet pipe 315, the control module 33 controls the second drive motor 341 to work, so that the sample bottle 32 on the connecting plate 343 rotates until the next sample bottle 32 rotates to the right below the first pipe section 3131 and the liquid outlet pipe 315, and prepares for sampling at the next sampling point, so as to achieve the purpose of rotating and lifting the sample bottle 32.

[0074] Embodiment 8, based on the above embodiment 7, in this embodiment, as Figure 4 As shown, a rubber cover 6 is provided at the tube mouth of the sample bottle 32; a first needle tube 7 is provided at the end of the first tube section 3131 close to the sample bottle 32; the cross-sectional area of ​​the first needle tube 7 gradually decreases from the end close to the first tube section 3131 to the end away from the first tube section 3131; a second needle tube 8 is provided at the end of the liquid outlet tube 315 close to the sample bottle 32; the cross-sectional area of ​​the second needle tube 8 gradually decreases from the end close to the liquid outlet tube 315 to the end away from the liquid outlet tube 315; the first needle tube 7 and the second needle tube 8 are used to insert the sample bottle 32 from the rubber cover 6.

[0075] Exemplarily, during implementation, the mouth of the sample bottle 32 is provided with a rubber cover 6 for sealing the sample bottle 32 to reduce the risk of water sample leakage from the mouth of the sample bottle 32 .

[0076] The first needle tube 7 is disposed at one end of the first tube section 3131 close to the sample bottle 32, and the cross-sectional area of ​​the first needle tube 7 gradually decreases from the end close to the first tube section 3131 to the end away from the first tube section 3131, so that the first needle tube 7 is in a tapered structure with a gradually increasing cross-sectional area from bottom to top. It is expected to achieve a smoother process of the first needle tube 7 piercing into the rubber cover 6 on the tube mouth of the sample bottle 32, thereby reducing the damage of the first needle tube 7 to the rubber cover 6 and extending the service life of the rubber cover 6.

[0077] The end of the liquid outlet tube 315 close to the sample bottle 32 is provided with a second needle tube 8, and the cross-sectional area of ​​the second needle tube 8 gradually decreases from the end close to the liquid outlet tube 315 to the end away from the liquid outlet tube 315, so that the second needle tube 8 is a tapered structure with a gradually increasing cross-sectional area from bottom to top. It is expected to achieve a smoother process of the second needle tube 8 piercing the rubber cover 6 on the tube mouth of the sample bottle 32, thereby reducing the damage of the second needle tube 8 to the rubber cover 6 and extending the service life of the rubber cover 6.

[0078] In the process that the control module 33 controls the electric telescopic rod 342 to extend so that the sample bottle 32 on the connecting plate 343 moves upward, the rubber cover 6 on the sample bottle 32 gradually fits on the lower end of the first needle tube 7. As the sample bottle 32 continues to rise, the first needle tube 7 penetrates into the rubber cover 6 so that the first tube section 3131 is connected with the sample bottle 32. At this time, the rubber cover 6 can fit tightly on the outer wall of the first needle tube 7 under the action of its own elastic force, in order to improve the sealing between the rubber cover 6 and the first needle tube 7, thereby reducing the risk of water sample leakage from the gap between the first needle tube 7 and the rubber cover 6. As the sample bottle 32 continues to rise, the rubber cover 6 on the sample bottle 32 gradually fits on the lower end of the second needle tube 8 until the second needle tube 8 penetrates into the rubber cover 6 and connects the sample bottle 32 and the rubber tube. At this time, the rubber cover 6 can be tightly attached to the outer wall of the second needle tube 8 under the action of its own elastic force, so as to improve the sealing between the rubber cover 6 and the second needle tube 8, thereby reducing the risk of water sample leakage from the gap between the second needle tube 8 and the rubber cover 6.

[0079] After the sampling of the sample bottle 32 is completed, the control module 33 controls the electric telescopic rod 342 to contract, so that during the downward movement of the sample bottle 32 on the connecting plate 343, the second needle tube 8 first slides out from the rubber cover 6 on the sample bottle 32. After the second needle tube 8 slides out from the rubber cover 6, the rubber cover 6 seals the punctured part of the second needle tube 8 under the action of its own elastic force. In the hope of reducing the risk of leakage of the water sample in the sample bottle 32 from the insertion position of the second needle tube 8. As the sample bottle 32 continues to move downward, the first needle tube 7 slides out from the rubber cover 6 on the sample bottle 32. After the first needle tube 7 slides out from the rubber cover 6, the rubber cover 6 seals the punctured part of the first needle tube 7 under the action of its own elastic force. In the hope of reducing the risk of leakage of the water sample in the sample bottle 32 from the insertion position of the first needle tube 7.

[0080] Example 9. On the basis of the above-mentioned Example 8, in this example, the process of connecting the sample bottle 32 with the first tube segment 3131 and the liquid outlet pipe 315 includes: S1. The control module 33 controls the second drive motor 341 to rotate to drive the sample bottle 32 to rotate to the bottom of the first tube segment 3131 and the liquid outlet pipe 315; S2. The control module 33 controls the electric telescopic rod 342 to extend to drive the first needle tube 7 on the first tube segment 3131 and the second needle tube 8 on the liquid outlet pipe 315 to penetrate the rubber tube on the sample bottle 32.

[0081] Exemplarily, during the implementation process, after receiving the sampling instruction from the remote terminal 1, the control module 33 first controls the second drive motor 341 to rotate, so that a sample bottle 32 on the connecting plate 343 rotates to the right below the first pipe section 3131 and the liquid outlet pipe 315. Then, the control module 33 controls the electric telescopic rod 342 to extend, so that the sample bottle 32 on the connecting plate 343 moves upward, so that the first needle tube 7 on the first pipe section 3131 and the second needle tube 8 on the liquid outlet pipe 315 penetrate into the rubber cover 6 on the sample bottle 32. During the extension of the electric telescopic rod 342, the rubber cover 6 on the sample bottle 32 gradually fits the lower end of the first needle tube 7. As the sample bottle 32 continues to rise, the first needle tube 7 penetrates into the rubber cover 6, so that the first pipe section 3131 is connected to the sample bottle 32. At this time, the rubber cover 6, under the action of its own elastic force, fits tightly to the outer wall of the first needle tube 7, improves the sealing performance, and reduces the risk of water sample leakage. As the sample bottle 32 continues to rise, the rubber cover 6 on the sample bottle 32 gradually fits against the lower end of the second needle tube 8 until the second needle tube 8 penetrates into the rubber cover 6 and connects the sample bottle 32 and the liquid outlet tube 315. At this time, the rubber cover 6, under the action of its own elastic force, fits tightly against the outer wall of the second needle tube 8, improving the sealing performance and reducing the risk of water sample leakage.

[0082] Embodiment 10, based on the above-mentioned embodiment 9, in this embodiment, the process in which the control module 33 controls the rotation of the second drive motor 341 includes: S01. After the sampling of the first sample bottle 32 is completed; S02. The control module 33 controls the second drive motor 341 to rotate 180° to sample the second sample bottle 32; S03. After the sampling of the second sample bottle 32 is completed, the control module 33 controls the second drive motor 341 to rotate 360° / n to sample the third sample bottle 32; repeat steps S2 and S3 until the sampling of n sample bottles 32 is completed.

[0083] Exemplarily, during the implementation process, a sample bottle 32 is randomly selected as the first sample bottle 32. After the sampling of the first sample bottle 32 is completed. The control module 33 controls the second drive motor 341 to rotate 180°, so that the second sample bottle 32 on the connecting plate 343 rotates to the first pipe section 3131 and the liquid outlet pipe 315, and prepares to sample the second sample bottle 32. After the sampling of the second sample bottle 32 is completed, the control module 33 controls the second drive motor 341 to rotate 360° / n (n is the number of sample bottles 32), so that the third sample bottle 32 on the connecting plate 343 rotates to the first pipe section 3131 and the liquid outlet pipe 315, and prepares to sample the third sample bottle 32. After the sampling of the third sample bottle 32 is completed, the control module 33 controls the second drive motor 341 to rotate 180°, so that the fourth sample bottle 32 on the connecting plate 343 rotates to the first pipe section 3131 and the liquid outlet pipe 315, and prepares to sample the fourth sample bottle 32. After the fourth sample bottle 32 has been sampled, the control module 33 controls the second drive motor 341 to rotate 360° / n (n is the number of sample bottles 32), so that the fifth sample bottle 32 on the connecting plate 343 rotates to the bottom of the first pipe section 3131 and the liquid outlet pipe 315, and is ready to sample the fifth sample bottle 32. And so on, until the n sample bottles 32 have been sampled. Through this sampling sequence, the sample bottles 32 that have been sampled can be effectively arranged on both sides of the flying carrier 2, so as to balance the center of gravity of the flying carrier 2 and reduce the risk of the flying carrier 2 rolling over.

[0084] Among them, in an optional implementation, during the sampling process, the water sample of a sampling point can be synchronously transported to four adjacent sample bottles 32 with an interval of 90°, so that the sample bottles 32 after sampling can be effectively arranged around the flying carrier 2, thereby balancing the center of gravity of the flying carrier 2 and reducing the risk of the flying carrier 2 rolling over.

[0085] The working process of a mobile water quality sampling system in plateau or mountainous areas in this embodiment is as follows:

[0086] S100. Before sampling the target water area, the second pipe section 3132 is wound around the pipe reel 312, and the sampling pump 314 is turned off.

[0087] S101. When sampling is required in the target water area, the number of sample bottles 32 on the connecting plate 343 is first set according to the number of sampling points in the target water area. Next, the remote terminal 1 constructs a sampling route according to the location of the sampling point and the water flow speed in the sampling point, and generates a flight instruction and a sampling instruction.

[0088] S102. After receiving the flight instruction, the flying vehicle 2 flies to the first sampling point on the sampling route according to the sampling route.

[0089] S103 . When the flying vehicle 2 flies to the first sampling point, the remote terminal 1 sends a sampling instruction to the control module 33 .

[0090] S104. During sampling, after receiving the sampling instruction from the remote terminal 1, the control module 33 first controls the first drive motor 311 to rotate forward to release the second pipe section 3132 until the sampling pump 314 descends to the target sampling position of the sampling point. Secondly, the control module 33 controls the second drive motor 341 to rotate so that a sample bottle 32 on the connecting plate 343 rotates to the right below the first pipe section 3131 and the liquid outlet pipe 315. Then, the control module 33 controls the electric telescopic rod 342 to extend so that the sample bottle 32 on the connecting plate 343 moves upward until the first needle tube 7 on the first pipe section 3131 and the second needle tube 8 on the liquid outlet pipe 315 penetrate into the rubber cover 6 on the sample bottle 32. Finally, the control module 33 controls the sampling pump 314 to transport the water sample in the sampling point to the sample bottle 32.

[0091] S105. When the sampling is completed, the control module 33 first controls the electric telescopic rod 342 to retract, so that the sample bottle 32 on the connecting plate 343 moves downward, until the first needle tube 7 on the first pipe section 3131 and the second needle tube 8 on the liquid outlet pipe 315 slide out from the rubber cover 6 on the sample bottle 32. Then, the control module 33 controls the second drive motor 341 to rotate 180°, so that the second sample bottle 32 on the connecting plate 343 rotates to the right below the first pipe section 3131 and the liquid outlet pipe 315. At the same time, the control module 33 controls the first drive motor 311 to rotate in the opposite direction to reel up the second pipe section 3132.

[0092] S106. After the second pipe section 3132 is rolled up, the flying carrier 2 flies along the sampling route to the second sampling point on the sampling route.

[0093] After the sampling operation in S104 completes the sampling of the second sample bottle 32, the control module 33 controls the second driving motor 341 to rotate 306° / n, so that the third sample bottle 32 on the connecting plate 343 rotates to the position directly below the first pipe section 3131 and the liquid outlet pipe 315. This continues until the sampling of n sample bottles 32 is completed.

[0094] After the control module 33 controls the second driving motor 341 to rotate, the flying carrier 2 moves to the next sampling point. In this process, the sample bottles 32 after sampling can be effectively arranged on both sides of the flying carrier 2, so as to balance the center of gravity of the flying carrier 2 and reduce the risk of the flying carrier 2 rolling during flight.
