Specific implementation mode

Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.

As shown in Figure 1, a kind of column sediment sampler, including sampling head 1, probe tube 3, stop collar 4, tail pipe 6, connecting rod 7, lifting rope 8, the sampling head 1 are connect by sleeve A 2 with the lower part of probe tube 3, and the stop collar 4 is sleeved on outside probe tube 3, 3 top of the probe tube is connect by casing B5 with 6 lower part of tail pipe, and 6 top of the tail pipe passes through fixing bolt 9 and connecting rod 7 Lower part connects, as shown in Fig. 2, being equipped with sample sack 10 in the probe tube 3, the sample sack 10 is sleeved in probe tube 3, and 10 lower openings of sample sack turn up rear enclosure at 3 lower openings of probe tube, and 10 lower part of the sample sack is set with rope sling 11, described Rope sling 11 is connect with lifting rope 8, when using sampler, sampling head 1 is inserted into the bed mud for needing to sample, the overlying water on bed mud upper layer Entered in sampler by sampling head 1 with bed mud, is stored in the water sample pipe 12 that overlying water is entered by probe tube 3 in tail pipe 6, bed mud storage There are in probe tube 3, stop collar 4 can limit the insertion depth of sampler, after sampling goes to be inserted into predetermined depth, pass through drawing Dynamic lifting rope (8), sampler is pulled out from bed mud, and lifting rope (8) lower end is connect with rope sling 11, when pulling lifting rope (8), drives rope sling 11, rope sling 11 shuts 10 lower part of sample sack after tensing, and sample can be prevented to be lost in during sampler moves up, pulled out After going out sampler, sample sack 10 is pulled out from sampling head 1 is interior, and 10 other end of sample sack is clamped using sealing clip, then passed through Sample in sample sack 10 is separated by multiple sealing clips by different mud layers, prevents sample different mud layers in transit Bed mud mixes, and impact analysis is stored in as a result, the overlying water sample being discharged simultaneously in water sample pipe 12 in tank.

The tail pipe 6 is equipped with multiple vertically disposed adjustment holes 14, can adjust the position of water sample pipe 12.

As shown in figure 3, being equipped with water sample pipe 12 in the tail pipe 6, water sample pipe 12 is installed by fixed link 13 and adjustment hole 14 In tail pipe 6, when overlying water enters tail pipe 6, prevent water sample pipe 12 from being moved by buoyancy.

12 upper and lower part of water sample pipe is designed with non-return baffle 15, and 15, non-return baffle allows overlying water by water sample pipe 12 flow up, and prevent when extracting sampler, and overlying water inversely flows into probe tube, impact analysis result.

12 lower part of water sample pipe is additionally provided with discharge outlet, and rubber tube 16 is cased in discharge outlet, one is equipped in rubber tube 16 Bead 17 pinches the rubber tube 16 at bead 17, rubber tube hair when the overlying water sample for needing to be discharged in water sample pipe 12 Gap is generated after raw deformation, overlying water sample is flowed out by gap.

Filter screen is equipped between the probe tube 3 and tail pipe 6, for filtering out larger impurity in water.

The stop collar 4 is equipped with locking nut 18, and can stop collar 4 probe tube 3 be fixed on by locking nut 18 On, when sampling goes to be inserted downwardly into predetermined depth, since 4 lateral cross section of stop collar is larger, sampler can be prevented to continue to insert Enter in bed mud.

7 one end of the connecting rod is equipped with internal thread, and the other end is equipped with external screw thread, when the water at sampling is too deep, can pass through More connecting rods 7 can be connected with each other, and extend the length of sampler, when without using connecting rod 7, can be separated, convenient for taking Band.
