The placement slots 08 are adapted to the dispensing tube 07, and the dispensing tube 07 is connected to the placement slot 08. A plurality of lifting rings 01 are evenly distributed on the upper part of the sampling barrel 02, so that it is convenient for it to be fixedly connected to the lifting equipment through a lifting rope, thereby ensuring the stability of the sampling barrel 02 when it is lowered and lifted up, and the depth of the sampling barrel 02 lowered into the water can be adjusted accordingly according to actual sampling needs, so as to facilitate environmental engineering pollutants. The sampling barrel 02 is provided with a fixed bottom plate 30 at the bottom, and the fixed bottom plate 30 has a plurality of diversion holes 05. The lower part of the fixed bottom plate 30 is connected to the sub-filling tube 07, and the sub-filling tube 07 has a support sleeve groove 12. The fixed bottom plate 30 has a plurality of mounting support sleeves 06. The mounting support sleeves 06 are adapted to the support sleeve groove 12, and the mounting support sleeves 06 are connected to the support sleeve groove 12. When the sampling barrel 02 is lowered to the sampling depth by the lifting equipment, the sampling barrel 02 salvages the sampled water. After the water enters the sampling barrel 02, it enters the sub-filling tube 07 through the diversion hole 05, completing the rapid packaging of multiple groups of samples. After the sampling is completed, the sampling barrel 02 is lifted and removed by the lifting equipment, and then the sampling seat 09 is quickly separated from the sampling barrel 02 by turning the knob 13. At this time, the sub-filling tube 07 can be quickly removed for different project tests. There is no need to manually pour the water collected in the sampling barrel 02 into different test sampling tubes one by one. The operation is convenient, and the efficiency of environmental engineering pollutant sampling operations is improved.

[0024] Example 2:

[0025] The supporting base plate 11 of the present invention has a central column 16, and the fixed base plate 30 has a column groove 17. The central column 16 is adapted to the column groove 17, and the central column 16 is connected to the column groove 17.

The positioning lock block 19 passes through the locking block through-hole 21, and the positioning lock block 19 is connected to the positioning lock groove 20.

[0026] Example 3:

[0027] The driving gear plate 22 of the utility model has a pad 24, the pad 24 fits the center column 16, the pad 24 has a driving rod 14, the center column 16 has a driving rod through-hole 15, the driving rod 14 is adapted to the center column 16, the driving rod 14 passes through the driving rod through-hole 15, the driving rod 14 is connected to the knob 13, the knob 13 fits the supporting bottom plate 11, this device can sample water while packaging the samples, which is convenient for testing different items of pollutant sampling, and there is no need to manually pour the water collected in the sampling bucket 02 into different test sampling tubes one by one, the operation is convenient, and the efficiency of environmental engineering pollutant sampling operations is improved.

[0028] Example 4:

[0029] The driving gear plate 22 of the utility model is meshed with the driven gear plate 23, and the driving gear plate 22 is connected to the driven gear plate 23. The driven gear plate 23 has a control rod 25, which passes through the supporting plate 26. The control rod 25 is connected to the positioning lock block 19 by a thread. The driving gear plate 22 and the driven gear plate 23 are meshed and connected, so that when the driving gear plate 22 is driven to rotate by turning the knob 13, the driven gear plate 23 and the control rod 25 are linked. The two sides of the control rod 25 are respectively connected to the positioning lock blocks 19 on both sides by positive and negative threads, so that when the control rod 25 is rotated, the driven gear plate 23 and the control rod 25 are linked. During rotation, the positioning lock blocks 19 on both sides simultaneously perform synchronous horizontal linear displacement inward or outward. When the positioning lock block 19 moves outward until it is embedded in the positioning lock groove 20, the connection fulcrum between the sampling barrel 02 and the sampling seat 09 can be increased to prevent the two from rotating and separating, resulting in the misalignment of the diversion hole 05 and the filling tube 07, thereby ensuring that the sampled water enters the filling tube 07 smoothly. When the positioning lock block 19 moves inward until it is completely separated from the positioning lock groove 20, the fixed fulcrum between the sampling barrel 02 and the sampling seat 09 disappears. At this time, the two can be quickly separated to facilitate the removal of the sampled filling tube 07, which is convenient to operate.
