A sampling tube port 12 is fixed through the top surface of the sealing disk 4 on the side of the sealing cover 1 6, and a sealing cover 2 13 is threadedly sleeved on the top surface of the sampling tube port 12.

[0027] Specifically, when the sampling and collecting device needs to be used, first insert the cleaned sampling tubes 3 into the positioning groove 2 one by one, and make the sampling tube 3 abut against the top surface of the supporting plate 1, put the positioning groove 2 on the outside of the sampling tube 3, and make the sealing plate 4 pass through the inner spiral tube 5, then put the push rod 9 into the receiving groove 16, and then screw the sealing cover 1 6 and the sealing cover 2 13 onto the inner spiral tube 5 and the sampling tube mouth 12 respectively to fix. When sampling is needed, first screw the sealing cover 1 6 to open the receiving groove 16, and take the sealing cover 1 6 out of the receiving groove 16. After taking it out, screw the sealing cover 1 6 onto the inner spiral tube 5 again, and limit the positioning groove 2, and then screw the sealing cover 2 13 to open the sampling tube mouth 12. When sampling, first push the rubber piston 7 to the side close to the supporting plate 1, place the sampling tube mouth 12 in the water, and align and engage the connecting block 10. To the inside of the connecting card slot 11, and rotate the push rod 9 so that the connecting card block 10 is engaged with the inside of the sampling tube 3. The rubber piston 7 can be pulled by the push rod 9 and the connecting card block 10 to extract the water sample. After the extraction is completed, the push rod 9 is rotated to pull the connecting card block 10 out of the connecting card slot 11, and then the positioning slot 2 is rotated to align the sampling tube mouth 12 with the next sampling tube 3, and the connecting card block 10 is connected to the connecting sleeve block 8 inside the next sampling tube 3, and sampling can be carried out. After the sampling is completed, the push rod 9 is separated from the connecting sleeve block 8, and the sealing cover 6 is twisted to open the storage groove 16. After the sealing cover 6 is put in, the sealing cover 6 is twisted to press the positioning slot 2 so that the positioning slot 2 presses the sealing gasket 15 to seal. After sealing, the inner plug rod 14 is inserted into the sampling tube mouth 12, and the sampling tube mouth 12 and the sealing cover 13 are twisted to fix them.

[0028] As an optimization solution, Figure 3 and Figure 5As shown, a receiving groove 16 is provided at the center of the inner spiral tube 5 and the support disk 1, and the diameter of the receiving groove 16 is larger than the diameter of the push rod 9, and the height of the receiving groove 16 is larger than the sum of the heights of the push rod 9 and the connecting block 10. A sealing gasket 15 is fixed to the top surface of each inner spiral tube 5, and the top surface of the sealing gasket 15 is slidably fitted with the inner top surface of the sealing disk 4, the inner ring diameter of the sampling tube mouth 12 is smaller than the inner ring diameter of the sampling tube 3, an inner plug rod 14 is fixed to the inner bottom surface of the sealing cover 13, and the outer surface of the inner plug rod 14 is slidably fitted with the inner wall of the sampling tube mouth 12, and the height of the inner plug rod 14 is equal to the height from the top surface of the sampling tube mouth 12 to the top surface of the sampling tube 3.

[0029] Specifically, after the sampling is completed, the push rod 9 and the connecting card block 10 can be inserted into the storage groove 16, so that the push rod 9 is more convenient and labor-saving when stored, and it is more convenient to carry. The sliding fit design between the top surface of the sealing gasket 15 and the top surface of the inner wall of the positioning groove 2 can prevent the water inside the sampling tube 3 from flowing out when the sampling point is changed, and the sampling tube mouth 12 is blocked by the inner plug rod 14. After blocking, the interior of the sampling tube 3 can be kept sealed. After all sampling is completed, the collection device can be sealed as a whole.
