Some also refer to the relatively stable environment of natural waters bounded by land.

[0003] At present, when managing the water environment, it is often necessary to take samples of water in the river for subsequent testing. Especially when sampling deeper water bodies, auxiliary tools are needed to complete the sampling. However, in actual use, the existing auxiliary sampling device is inconvenient to open and close the water inlet of the device submerged in water. Not only is the efficiency low and the stability poor, but the water inlet range is limited, and it is easy to carry more gravel and impurities into it, which greatly affects the sampling effect.

[0030] A sampling tube 1, the top of which is connected to a hanging rope 2, a driving chamber 4 is provided at the top of the sampling tube 1, and a water collection chamber 5 is provided at the bottom of the sampling tube 1;

[0031] A sealing plate 3 is provided at the bottom end of the sampling tube 1, and a filter cartridge 6 is fixed on the top side of the sealing plate 3, the filter cartridge 6 is inserted into the water intake cavity 5, and a limit ring 7 is connected to the top end of the filter cartridge 6;

[0032] A connecting shaft 8 is rotatably connected to the inner bottom end of the driving chamber 4, and a toothed disc 9 is fixed to the top of the connecting shaft 8. A plurality of rotating rods 11 are rotatably connected to the interior of the driving chamber 4 in an annular array. Gears 12 meshing with the toothed disc 9 are fixed to the tops of the plurality of rotating rods 11. A plurality of through holes 13 are provided in an annular array on the side of the sampling tube 1 and outside the water intake chamber 5. The bottom end of the rotating rod 11 passes through the through hole 13 and is provided with a threaded section 14. A plurality of threaded channels 24 are provided in an annular array on the side wall of the sealing plate 3. One end of the threaded section 14 passes through the threaded channel 24 and is connected to a stopper 15.

[0033] A motor 10 is fixed to the inner top of the driving cavity 4 , and an output end of the motor 10 is fixedly connected to the connecting shaft 8 .

[0034] The bottom of the toothed disc 9 is provided with a plurality of slide posts 16 in a circular array, and the inner bottom side of the driving chamber 4 is provided with a slide groove 17 matching the slide posts 16. By providing the slide posts 16 and the slide groove 17, when the toothed disc 9 rotates, the toothed disc 9 can drive the slide posts 16 to slide in the slide groove 17. With the cooperation of this structure, the stability of the toothed disc 9 during rotation can be greatly improved.

[0035] The sampling tube 1 can be put into the water through the hanging rope 2. After sinking to the specified depth, the connecting shaft 8 can be driven to rotate by the motor 10, so that the connecting shaft 8 drives the toothed disc 9 to rotate, and then the toothed disc 9 can drive multiple gears 12 to rotate at the same time, so that the gear 12 drives the rotating rod 11 to rotate, and then the rotating rod 11 drives the threaded section 14 to rotate. Under the action of the threaded channel 24, the sealing plate 3 can be made to descend along a straight line, and then the sealing plate 3 drives the filter cartridge 6 to move, so that the filter cartridge 6 drives the limiting ring 7 to slide in the water intake chamber 5, so that the opening of the water intake chamber 5 can be fully opened, and then the water body can quickly flow into and fill the water intake chamber 5, which is highly efficient. After that, the motor 10 drives the toothed disc 9 to rotate in the opposite direction, so that the sealing plate 3 can quickly rise and close the opening of the water intake chamber 5;

[0036] At the same time, under the interception of the filter cartridge 6, gravel impurities carried in the water body can be effectively prevented from entering the water intake chamber 5, thereby facilitating the opening and closing control. It is not only efficient and stable, but also can effectively avoid the mixing of gravel impurities, greatly improving the sampling effect.

When connected, the block 15 can block the sealing plate 3 to prevent the sealing plate 3 from directly detaching from the threaded section 14. When separated, the sealing plate 3 can also drive the filter cartridge 6 to be completely separated from the sampling cartridge 1, thereby facilitating water collection or cleaning.

[0039] The utility model provides Figure 1 , Figure 2 , Figure 5 and Figure 6 In the water environment management auxiliary sampling device shown, a first fixing ring 20 is fixed to the top side wall of the sealing plate 3, a second fixing ring 21 is fixed to the bottom side wall of the sampling tube 1, and a clamping assembly is provided between the first fixing ring 20 and the second fixing ring 21.

[0040] The clamping assembly includes two clamping rings 22 connected to the top of the first fixing ring 20 , and two clamping grooves 23 matching with the clamping rings 22 are formed on the bottom side of the second fixing ring 21 .

[0041] When the sealing plate 3 closes the opening of the water intake chamber 5, the first fixing ring 20 can be in contact with and fit the second fixing ring 21, and at the same time, the two clamping rings 22 on the first fixing ring 20 can be inserted into the two card grooves 23 on the second fixing ring 21. The two groups of clamping rings 22 and the card grooves 23 are plugged into and matched with each other, thereby further forming a multi-channel sealing waterproof belt structure between the first fixing ring 20 and the second fixing ring 21, which can greatly improve the sealing performance during connection, effectively avoid the infiltration of external water or the leakage of internal water, and ensure the accuracy of the sampling and detection results.
