Accurate monitoring of water environment data is the key to assessing water quality, formulating water resource protection strategies, and preventing water pollution. Monitoring of deep water bodies is particularly challenging. Traditional water sampling methods often have many limitations. For example, simple surface water sampling cannot fully reflect the true situation of deep water bodies, because deep water bodies may have significant differences in physical, chemical and biological properties from the surface. In the period when technology was relatively backward, some sampling equipment had low accuracy and it was difficult to obtain representative water samples, which greatly reduced the accuracy and reliability of monitoring data. Moreover, the early equipment was complicated to operate, required a lot of manpower and time, and was inefficient. With the continuous advancement of science and technology, people have higher and higher requirements for the accuracy, comprehensiveness and real-time nature of water environment data. Therefore, it is imperative to develop an efficient, accurate and reliable deep water sampling equipment.

The filtering device 69 is sleeved on the outer side of the sealing device 68. Both the sealing device 68 and the filtering device 69 are provided in multiple groups.

[0023] The sealing device 68 includes a sliding plug 681, a first sealing sleeve 682 is sleeved on the outer side of the sliding plug 681 near the end, a second sealing sleeve 683 is sleeved on the outer side of the sliding plug 681 away from the first sealing sleeve 682, a sealing baffle 684 is sleeved on the outer side of the sampling tube 65 and fixedly connected, a return spring 685 is fixedly connected to the end of the sliding plug 681 close to the first sealing sleeve 682, an end of the return spring 685 away from the sliding plug 681 is fixedly connected to a limiting plate 686, a limiting bracket 687 is fixedly connected to the outer side of the limiting plate 686, a connecting plate 688 is fixedly connected between the first sealing sleeve 682 and the second sealing sleeve 683, a positioning bracket 689 is fixedly connected to one side of the connecting plate 688, and a rolling ball 6810 is rotatably connected to the outer side of the positioning bracket 689 through a bearing.

[0026] When in use, the operator places the buoyancy board 1 on the water surface of the water area to be tested, and then uses the spiral propulsion mechanism 5 to drive the buoyancy board 1 to move. When the buoyancy board 1 moves to the specified position, the lifting mechanism 4 is turned on to drive the sampling tube 61 to dive into the water body. As the sampling tube 61 gradually descends, the water pressure on the sliding plug 681 gradually increases, and the sliding plug 681 pushed by the water pressure slides toward the inside of the sampling tube 65. When the sampling tube 61 dives to the specified position, the first sealing sleeve 682 on the top completely enters the inside of the sampling tube 61.

Water bodies at different depths can be classified and sampled, thereby improving the sampling efficiency. After the sampling is completed, the sampling cylinder 61 rises, and the water pressure on the sliding plug 681 gradually decreases, driving the first sealing sleeve 682 and the second sealing sleeve 683 to move in the opposite direction. When the second sealing sleeve 683 withdraws from the sampling tube 65, the external water body can enter the interior of the sampling cylinder 61 from the position between the first sealing sleeve 682 and the second sealing sleeve 683, thereby completing the secondary sampling at the same position. The two samplings make the sample data more accurate.

The filter barrel 694 can filter out impurities and floating objects mixed in the water to prevent impurities from entering the sampling barrel 61 along with the water flow, thereby improving the accuracy of sampling.

[0031] Open the annular slide rail 696, and the movable plate 698 is driven to move by the electric slider 697 inside the annular slide rail 696.

At this time, the external water sample can pass through the first The position between the sealing sleeve 682 and the second sealing sleeve 683 enters the interior of the sampling tube 61. As the sampling tube 61 continues to descend, the water pressure on the sliding plug 681 continues to increase. When it descends to a certain position, the water pressure pushes the sliding plug 681 to drive the second sealing sleeve 683 to block the sampling tube 65. At this time, the sampling tube 61 is in a sealed state, and the initial sampling can be completed. At this depth, the sliding plug 681 below still blocks the sampling tube 65 through the first sealing sleeve 682 through the supporting force of the return spring 685. When the sampling tube 61 continues to dive, the sliding plug below The water pressure on 681 continues to increase, and the above process is repeated when diving further, so that sampling of deeper water can be carried out. After the sampling is completed, the sampling tube 61 rises, and the water pressure on the sliding plug 681 gradually decreases, driving the first sealing sleeve 682 and the second sealing sleeve 683 to move in the opposite direction. When the second sealing sleeve 683 withdraws from the sampling tube 65, the external water can enter the sampling tube 61 from the position between the first sealing sleeve 682 and the second sealing sleeve 683, and the secondary sampling at the same position can be completed. When the sampling tube 61 dives to the designated position for sampling, the water passes through The filter holes 695 on the filter cartridge 694 then enter the sampling tube 65. The filter cartridge 694 can filter out impurities and floating objects mixed in the water to the outside, preventing impurities from entering the sampling cartridge 61 along with the water flow. The annular slide rail 696 is opened, and the moving plate 698 is driven to move by the electric slider 697 inside the annular slide rail 696. The moving plate 698 drives the brush plate 699 to rotate while the moving plate 698 moves. The brush plate 699 can clean the filter cartridge 694 along the surface of the filter cartridge 694 when it moves back and forth, preventing impurities from accumulating on the outside of the filter cartridge 694 and clogging the filter holes 695.
