Scale lines 11 are processed on the outer wall surface of the sampling tube 1, which improves the accuracy of sampling. A lifting handle 10 is fixedly installed on the side wall of the sampling tube 1, which is convenient for the operator to hold and move the sampling device. Anti-slip patterns are processed on the outer wall surface of the lifting handle 10, which enhances the stability of grasping, prevents slipping during the operation process, and improves the safety of use.

[0025] Refer to the attached Figure 1 and Figure 2 For the sampling tube 1, it includes a top tube 101 and a bottom tube 102. Connecting blocks 103 are fixedly installed at the bottom of the top tube 101 and the top of the bottom tube 102. Bolt holes are provided on the connecting blocks 103. A rubber gasket is also provided between the top tube 101 and the bottom tube 102. During assembly, the connection between the top tube 101 and the bottom tube 102 is realized by bolts and the connecting blocks 103. The setting of the rubber gasket increases the sealing performance of the connection part and prevents liquid leakage during the sampling process.

[0026] Refer to the attached Figure 1 、 Figure 3 and Figure 4 For the sampling tube 1, a bracket 2 is fixedly installed at the top. An electric telescopic rod 3 is fixedly installed on the bracket 2. The piston rod of the electric telescopic rod 3 extends into the interior of the sampling tube 1, and a rubber block 4 is fixedly installed at the end of the piston rod. A sampling port 5 is eccentrically arranged at the bottom of the sampling tube 1. A filter plate 6 is arranged below the sampling port 5. The filter plate 6 filters small sundries. The filter plate 6 is threadedly connected to the sampling port 5, which is convenient for replacing the filter plate 6.

[0027] Refer to the attached Figure 1 and Figure 2A connecting rod 7 is rotatably installed at the middle position of the bottom of the sampling tube 1, and a sweeping plate 8 is fixedly installed on the connecting rod 7. The connecting rod 7 and the sweeping plate 8 are vertically arranged. A driving component 9 for realizing the rotation of the connecting rod 7 is arranged on the sampling tube 1.

[0028] When in use, the operator turns on the motor 905, and the output shaft of the motor 905 drives the transmission rod 902 to rotate. Under the action of the two pulleys 903 and the transmission belt 904, the connecting rod 7 is rotated, and then the sweeping plate 8 is rotated. The sweeping plate 8 pushes away the debris, preliminarily preventing the debris from entering the sampling tube 1, thereby improving the sampling quality, realizing the automatic cleaning function, reducing manual intervention, and improving work efficiency and safety.

[0029] The NMP sampling device controls the movement of the rubber block 4 in the sampling tube 1 through the electric telescopic rod 3 to collect the sample, and at the same time uses the motor 905 to drive the sweeping plate 8 to rotate.
