[0026] This utility model provides, for example Figures 1 to 6 The water environment treatment auxiliary sampling device shown includes:

[0027] Support plate 1, on which a depth adjustment component is provided;

[0028] Placement plate 2, with a connecting plate 3 fixedly provided at the top of placement plate 2, and two sampling bottles 4 opened at the top of placement plate 2. The two sampling bottles 4 are respectively located on both sides of the connecting plate 3. Placement plate 2 is provided with two placement slots 5, the bottom ends of the two placement slots 5 extend into the interior of the two sampling bottles 4 respectively. A sealing plate 6 is provided at the top of the two placement slots 5, and two rubber stoppers 7 are fixedly provided at the bottom of the sealing plate 6. The two rubber stoppers 7 extend into the interior of the two sampling bottles 4 respectively.

[0029] Two water inlet pipes 8 are provided. One end of each water inlet pipe 8 passes through the sealing plate 6 and the rubber stopper 7 and is connected to the inside of the two sampling bottles 4. The other end of each water inlet pipe 8 passes through the placement plate 2 and extends to the bottom of the placement plate 2. A suction pump 10 is fixedly installed at the bottom of the support plate 1. A suction pipe 11 is connected to the suction pump 10. Two air outlet pipes 9 are fixedly installed at the outer end of the suction pipe 11. One end of each air outlet pipe 9 passes through the sealing plate 6 and the rubber stopper 7 and is connected to the inside of the two sampling bottles 4.

[0030] The depth adjustment assembly includes a motor 12 fixedly mounted on the top of the support plate 1. The output shaft of the motor 12 is fixedly equipped with a winding rod 13. One end of the winding rod 13 is rotatably connected to the top of the support plate 1 via a bearing seat. Two pull ropes 14 are wound around the outer end of the winding rod 13. One end of the pull ropes 14 is fixedly connected to the top of the connecting plate 3. A connecting opening 15 is provided at the top of the support plate 1. One end of each of the two pull ropes 14 passes through the interior of the connecting opening 15. Two redirecting rollers 16 are provided at the top of the support plate 1. The two redirecting rollers 16 are respectively located on the front and rear sides of the winding rod 13. One end of each of the two pull ropes 14 passes around the outer ends of the two redirecting rollers 16. A counterweight 17 is fixedly provided at the bottom of the placement plate 2. The counterweight 17 is located between the other ends of the two water inlet pipes 8.

[0031] The connecting plate 3 has a movable groove 18. The sealing plate 6 passes through the interior of the movable groove 18. The top of the sealing plate 6 has a limiting plate 19. The top of the limiting plate 19 is rotatably connected to a threaded rod 20 through a bearing. The top of the threaded rod 20 passes through the top of the connecting plate 3 and is connected to the top of the connecting plate 3 through a thread. The top of the threaded rod 20 is fixedly provided with a rotating block 21. The front and rear walls of the movable groove 18 are provided with sliding grooves 22. The sliding grooves 22 are provided with sliders 23. The two sliders 23 are fixedly connected to the front and rear ends of the limiting plate 19, respectively.

[0032] Connect one end of the support plate 1 to the support and fixing structure on the shore, start the motor 12, the output shaft of the motor 12 drives the winding rod 13 to rotate, the winding rod 13 lowers the pull rope 14 on it, and the placement plate 2 and the connecting plate 3 will enter the water body under the elastic force of the counterweight 17.

[0033] Once the placement plate 2 and the structure on it have reached the designated depth in the water, the suction pump 10 is started. The suction pump 10 blows air into the two sampling bottles 4 through the suction pipe 11 and the two air outlet pipes 9. The air inside the sampling bottles 4 is blown out through the water inlet pipe 8, which blows out the water at the opening of the water inlet pipe 8. Then, the suction pump 10 extracts the air from the two sampling bottles 4 through the suction pipe 11 and the two air outlet pipes 9. The air pressure inside the sampling bottles 4 decreases, and the water sample enters the sampling bottle 4 through the water inlet pipe 8, thus completing the water sample collection.

[0034] The output shaft of motor 12 rotates in the opposite direction, and the winding rod 13 winds up the two pull ropes 14. The two pull ropes 14 drive the connecting plate 3 and the placement plate 2 away from the water body. Rotate the rotating block 21, and the rotating block 21 drives the threaded rod 20 to rotate. Since the threaded rod 20 is threadedly connected to the connecting plate 3, the threaded rod 20 moves upward with its own rotation. The threaded rod 20 drives the limiting plate 19 to move upward. At this time, the sealing plate 6 and the two rubber stoppers 7 are pulled upward, so that the two rubber stoppers 7 leave the two sampling bottles 4 respectively. Then the two sampling bottles 4 are removed, and the water sample can be taken out for testing.

[0035] This invention uses a depth adjustment component to adjust the depth of the placement plate 2, connecting plate 3, and sampling bottle 4 in the water body, enabling the collection of water samples at different depths. The suction pump 10 blows out and extracts air from inside the sampling bottle 4, adjusting the air pressure inside the bottle and thus removing excess water. Simultaneously, it allows for precise collection of water samples at specified depths. This embodiment specifically addresses the problem in existing water environment treatment auxiliary sampling devices where, in practical use, the sampling personnel typically hold a rod-shaped support structure and place the sampling bottle into the water for sampling. This sampling method is not suitable for sampling deep water and is inconvenient.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
