A lifting device 18 is installed on one side of the flow valve 12, and the lifting device 18 is installed on the equipment housing 1. It should be noted that the lifting device 18 belongs to the existing technology, and is composed of parts including an electric slide rail and an electric slider to achieve height adjustment of the flow valve 12. A linear hose 13 is installed at the lower end of the flow valve 12, and the puncture head 10 in the puncture and blanking component is used to puncture the rubber pad 9 to transport the liquid. At the same time, due to the characteristics of the rubber pad itself, the entry of external air is avoided when it is pulled out.

[0023] like Figure 2 and 3 As shown, the sampling mechanism includes a water pump 14, which is installed below the inner wall of the device housing 1. The output end of the water pump 14 is connected to the lower end of the linear hose 13. The input end of the water pump 14 passes through the device housing 1 and is installed with a connector 15. The outer wall of the connector 15 is threadedly installed with a sealing head 16. The interior of the sealing head 16 is connected to one end of the sampling tube 17.

[0026] The working principle of a water sample extraction device of this embodiment is as follows:

[0027] Push the device to the sampling location, open the magnetic slide 3, place several transparent containers 7 inside the rotating frame 5, take out the sampling tube 17 from the storage box 22, and install it on the connector 15, ensuring that the connector 15, the sealing head 16 and the sampling tube 17 are connected internally;

[0028] Start the water pump 14, which draws up a water sample through the sampling tube 17. After the water sample passes through the filter 19 to filter out impurities, it enters the connector 15. The water sample output from the connector 15 is transported through the linear hose 13. The flow valve 12 is controlled to adjust the flow of the water sample. The drive motor 6 drives the rotating frame 5 to rotate, so that one of the empty transparent containers 7 is aligned with the puncture head 10. The lifting device 18 controls the puncture head 10 to descend, puncturing the puncture rubber pad 9 in the sealing cover 8 on the corresponding transparent container 7. The water sample enters the transparent container 7 through the input tube 11 for storage;

[0029] According to actual needs, multiple water sample collections can be completed for one area or multiple areas. When collecting water samples from the same area, the rotating frame 5 is rotated and the transparent containers 7 are replaced in sequence to complete multiple water sample collections from the same area. When collecting water samples from multiple areas, multiple samplings are performed in different areas, and several transparent containers 7 store water samples from different areas. The water sampling device realizes the separate collection and storage of water samples from different areas through the coordinated work of several transparent containers 7, the rotating frame 5, the puncture and discharge assembly and the sampling mechanism, which facilitates subsequent detection and comparison and improves the accuracy of the detection data.
