[0016] Depend on Figure 1-4 A sampling device for water quality environment monitoring is provided, comprising a drone 1, a sampler mechanism 2 is arranged at the center of the bottom of the drone 1, a pumping mechanism 3 is arranged on the top of the sampler mechanism 2, and support legs 4 are fixedly connected to the left and right sides of the bottom of the drone 1 respectively;

[0017] The sampling mechanism 2 includes a sampling barrel 21, two support frames 22 and a servo motor 24. The sampling barrel 21 is a hollow cylindrical shell structure. The bottoms of the two support frames 22 are fixedly connected to the outer walls of the front and rear sides of the sampling barrel 21, and the tops of the two support frames 22 are fixedly connected to the bottom of the drone 1. A rotating barrel 23 is arranged inside the sampling barrel 21. The two ends of the rotating barrel 23 respectively pass through the centers of the front and rear sides of the sampling barrel 21 and are rotatably connected to the sampling barrel 21. The servo motor 24 is fixedly connected to the left side of the sampling barrel 21, and the output shaft of the servo motor 24 is fixedly connected to the left end of the rotating barrel 23. A plurality of partitions 25 are fixedly connected to the outer wall of the rotating barrel 23. A sealing ring 26 is fixedly connected to the outer wall edge of the partition 25 and the left and right sides of the rotating barrel 23. The sealing ring 26 is fitted with the inner wall of the sampling barrel 21, and a water outlet valve 27 is connected to the bottom edge of the right side of the sampling barrel 21.

[0018] The pumping mechanism 3 includes a pumping frame 31, the bottom of the pumping frame 31 is connected to the top of the sampling tube 21, the right side of the pumping frame 31 is connected to a pumping pump 32, the input end of the pumping pump 32 is connected to an extension tube 33, and the right side of the front of the pumping frame 31 is connected to a one-way exhaust valve 34. A battery 5 is installed on the outer wall of the sampling tube 21, and the outer wall of the sampling tube 21 is fixedly connected to the battery 5. The battery 5 is a rechargeable battery. The battery 5 is electrically connected to the pumping pump 32, and the battery 5 is electrically connected to the servo motor 24. The battery 5 supplies power to the pumping pump 32 and the servo motor 24. The connection relationship between the battery 5 and the pumping pump 32 and the servo motor 24 is a prior art, so it is not described in detail. The drone 1 is a prior art device.

[0019] When the sampling device for water quality environment monitoring of the utility model is needed, the drone 1 can be controlled to the required sampling position and the bottom end of the extension tube 33 can be immersed in water. Then the water pump 32 works and the water source of the sampling site is pumped into the water pumping frame 31 and the sampling tube 21 through the extension tube 33. After the water source enters the sampling tube 21, the internal gas is squeezed by the water source and then discharged from the one-way exhaust valve 34. After the above steps, the single sampling process is completed. By adopting the driving method of the drone 1, sampling can be carried out in waters that are inconvenient to wade in, such as sampling in water surrounded by swamps, mud, ice, etc., which makes up for the various disadvantages of manual sampling. Inconvenience, because the interior of the sampling tube 21 is divided into multiple independent spaces by the partition plate 25, after completing a single sampling, the servo motor 24 drives the rotating drum 23 and the partition plate 25 to rotate, so that the next water storage space and the water pumping frame 31 can be sampled relative to each other, and this reciprocating process can be completed at one time. Multiple sampling processes can be stored independently for each sampling sample, achieving the effect of easy use. When it is necessary to take out the sample, the water outlet valve 27 can be opened. Under the action of gravity, the water in the lowermost water storage space flows out, and then the sample is taken out. The water source in the remaining space can be pushed to the bottom of the sampling tube 21 by the servo motor 24 and the partition plate 25 and then taken out.
