[0035] In this implementation scheme: a movable plate 2 is set on the base plate 1, and the mounting sleeve 3 on the movable plate 2 is used to support the adjusting rod 4. The water pump 6 is connected to the water storage tank 8 through the connecting pipe 7, and the sample is extracted from the sampling head 14 through the sampling pipe 5. The adjusting rod 4 is slidably connected to the mounting sleeve 3, allowing the sampling head 14 to be adjusted in the vertical direction, which is suitable for sampling environments at different depths.

[0036] It should be noted that the sample inlet tube 5 is a retractable flexible tube.

[0037] Furthermore:

[0074] Working principle: A movable plate 2 is installed on the base plate 1. The mounting sleeve 3 on the movable plate 2 supports the adjusting rod 4. The water pump 6 is connected to the water storage tank 8 through the connecting pipe 7. The sample is extracted from the sampling head 14 through the sampling pipe 5. The adjusting rod 4 is slidably connected to the mounting sleeve 3, allowing the sampling head 14 to be adjusted in the vertical direction, which is suitable for sampling environments at different depths. The adjusting rod 4 is connected to the connecting plate 12 through the fixed plate 13. The other end of the connecting plate 12 is connected to the L-plate 11. The L-plate 11 is rotatably connected to the output shaft of the cylinder 10. The extension and retraction of the cylinder 10 drives the L-plate 11 to rotate, which in turn drives the adjusting rod 4 through the connecting plate 12. The mounting plate 3 slides within the mounting sleeve to adjust the height of the sampling head 14. The mechanical structure driven by the cylinder 10 provides precise height control, suitable for sampling needs at different depths, and reduces jamming or offset during adjustment. The movable plate 2 is connected to the threaded rod 21, and the servo motor 22 drives the threaded rod 21 to rotate, thereby allowing the movable plate 2 to move horizontally on the base plate 1. The horizontal movement mechanism driven by the servo motor 22 expands the sampling range, covering a larger area without manual handling of the equipment, and also facilitates the retrieval of the sampling head 14. The slide rail 18 on the base plate 1 is slidably connected to the movable plate 2, restricting the movement of the movable plate 2. The guide rail 18 provides a guiding function to ensure that the moving plate 2 moves in a straight line, preventing it from deviating during movement and ensuring the positioning accuracy of the sampling head 14. The limit block 19 and the stop block 20 limit the horizontal displacement range of the moving plate 2, preventing it from detaching from the base plate 1, thus enhancing the safety and stability of the equipment and avoiding damage to components due to operational errors. The sampling head 14 and the adjusting rod 4 are connected by a threaded connector 16 with a threaded groove 17 and a fixing sleeve 15, enabling detachable installation. The detachable design facilitates the replacement of different types of sampling heads 14, improving the versatility of the equipment. The filter head 25 at the lower end is connected by threads and can filter impurities in the sample, effectively preventing large particles from entering the sampling system, protecting the water pump 6 and the water tank 8, and extending the service life of the equipment. The sampling valve 9 allows the sample to be obtained without opening the entire water tank 8, making it easy to control the sampling volume and suitable for multiple testing needs. The casters 23 improve the portability of the equipment, especially suitable for outdoor or large-area testing scenarios. The swivel design allows the equipment to be operated flexibly in narrow spaces. The handle 24 on the top of the water tank 8 makes it easy to carry or move the entire equipment, making the equipment more convenient to move and reducing labor costs.
