[0025] The front end of the sampling sleeve 1 is threadedly connected to the drilling probe 2. The drilling probe 2 is conical. Six external sampling windows 5 are provided on the side wall of the sampling sleeve 1. A scale line 6 is provided on the side wall of the sampling sleeve 1 on one side of the external sampling window 5. A rotating slot 7 is provided on the upper end wall of the sampling sleeve 1. A handle 8 is provided on the sampling sleeve 1 on the opposite side of the rotating slot 7. The handle 8 is semi-annular.

[0026] The sampling rod 3 is sleeved in the sampling sleeve 1. The sampling rod 3 can be pulled and rotated in the sampling sleeve 1. A handle 4 is provided on the top of the sampling rod 3. A positioning block 10 corresponding to the rotating slot 7 is provided on the sampling rod 3. An inner sampling window 9 corresponding to the outer sampling window 5 is provided on the sampling rod 3. The sampling rod 3 corresponding to the inner sampling window 9 is hollow. A sample compartment slot 12 is provided on the sampling rod 3 at the bottom of the inner sampling window 9. A sample compartment 11 is provided in the sample compartment slot 12.

[0027] The rotating card slot 7 is an inverted T-shape, and the rotating card slot 7 includes a longitudinally arranged push-pull slot 71 and an open positioning slot 72 and a closed positioning slot 73 extending to both ends from the end of the push-pull slot 71. The top of the push-pull slot 71 passes through the top edge of the sampling sleeve 1, and the positioning block 10 is inserted from the top of the push-pull slot 71. The positioning block 10 is changed by rotating the handle 4 to move in the open positioning slot 72 and the closed positioning slot 73. When the positioning block 10 moves to the end of the open positioning slot 72, the outer sampling window 5 and the inner sampling window 9 overlap, and sampling is performed; when the positioning block 10 moves to the closed positioning slot 73, the outer sampling window 5 and the inner sampling window 9 are misaligned, and the sampling device is submerged or the sampling device is taken out after sampling;

[0028] A clamping edge 110 is provided on one side of the sample chamber 11. The clamping edge 110 corresponds to the sample chamber clamping slot 12 provided on the sampling rod 3. The sample chamber 11 is magnetically connected to the sampling rod 3. Magnetic sheets are provided on the clamping edge 110 and on the inner wall of the sample chamber clamping slot 12 to facilitate fixing and disassembly. The sample chamber 11 is cylindrical and has a closed bottom. Scale marks corresponding to the scale lines 6 on the sampling sleeve 1 are marked on the sample chamber 11 to facilitate identification during testing.

[0029] The drill head 2, sampling sleeve 1, and sampling rod 3 are all made of stainless steel with polished surfaces, and the inner wall of the sampling sleeve 1 is polished. The drill head 2 is conical, and the sampling sleeve 1 is easily inserted into the required depth of the corresponding filter material. The drill head 2 and the sampling sleeve 1 are detachably connected, which facilitates cleaning, sterilization, and drying of the drill head 2 and the sampling sleeve 1.

[0030] The handle 4 and the grip 8 are both provided with a rubber non-slip outer layer for easy operation;

[0031] When in use, first insert the sampling rod 3 into the sampling sleeve 1, and the positioning block 10 is inserted into the rotating slot 7 through the push-pull slot 71. The sampling rod 3 is rotated by the handle 4 to rotate the positioning block 10 into the closed positioning slot 73, so that the positions of the outer sampling window and the inner sampling window are kept staggered, and the outer sampling window is closed by the sampling rod 3 body;

[0032] Then, keep the relative positions of the sampling sleeve 1 and the sampling rod 3 unchanged, insert the sampling sleeve 1 into the ozone activated carbon filter through the handle 4, and observe the insertion depth of the sampling sleeve 1 through the scale line 6 to reach the predetermined required depth;

[0033] After reaching the desired depth, the sampling sleeve is fixed in position by the handle 8, and the sampling rod 3 is rotated toward the open positioning groove 72 by the handle 4, so that the positioning block 10 moves into the open positioning groove 72. At this time, the outer sampling window 5 of the sampling sleeve 1 and the inner sampling window 9 of the sampling rod 3 overlap, and the sampling is in the open state; the sampling sleeve 1 and the sampling rod 3 are rotated three times toward the open positioning groove 72 by the handle 4, so that the filter materials corresponding to different depths pass through the outer sampling window 5 and the inner sampling window 9 and enter the sample chamber 11;

[0034] The position of the sampling sleeve is fixed again by the handle 8, and the sampling rod 3 is rotated toward the closed positioning groove 73 by the handle 4, so that the positioning block 10 moves into the closed positioning groove 73. At this time, the outer sampling window 5 of the sampling sleeve 11 and the inner sampling window 9 of the sampling rod 3 are kept staggered, and the outer sampling window 5 of the sampling sleeve 1 is closed by the sampling rod 3 body to ensure that the filtered material sample is not mixed with other layers of filtered material. The sampling sleeve 1 is lifted upward by the handle 4, and the relative positions of the sampling sleeve 1 and the sampling rod 3 are kept unchanged, and the sampling is carried out for inspection;

[0035] During testing, the position of the sampling sleeve is fixed by the handle 8, and the sampling rod 3 is rotated toward the direction of opening the positioning groove 72 by the handle 4, so that the positioning block 10 is rotated to the push-pull groove 71, and the sampling rod is pulled out of the sampling sleeve by the handle 4, and the sampling chambers are taken out for testing.
