As shown in Figure 1 to Figure 3, a kind of embodiment of the utility model water sampler.The water sampling of the utility model Device includes: holding rod 1 and collecting bottle 2, and the holding rod 1 includes thief rod 3 and armed lever 4, the connecting pin of the thief rod 3 and arm The connecting pin of bar 4 is detachably connected, and the bottleneck of the collecting bottle 2 and the sampling end of the thief rod 3 are detachably connected.Water sample is adopted When collection, holding rod 1 is held, thief rod 3 is connected with collecting bottle 2, thief rod 3 drives collecting bottle 2 to be moved in water and carries out water Sample acquisition, finishes to water sampling, and thief rod 3 drives collecting bottle 2 to leave the water surface, since thief rod 3 and collecting bottle 2 detachably connect It connects, the separation of thief rod 3 Yu collecting bottle 2 may be implemented, collecting bottle 2 is backed out after water sampling, screws on bottle cap, complete a water sample Acquisition, it is integrated with bottling that water sampling may be implemented.Being detachably connected can be connected through a screw thread.

The sampling end of thief rod 3 is one end far from armed lever 4, and the sampling end of thief rod 3 can be equipped with nut 5, nut 5 Inside diameter ranges are 27.9mm-28.1mm, preferably 28mm.Nut 5 in this way on thief rod 3 may be implemented and 2 bottles of different acquisition bottle Mouth agrees with.The shape of the body of collecting bottle 2 is cylindricality, and the shape of holding rod 1 is cylindricality, the axis and hand of the body of collecting bottle 2 The axis perpendicular of bar 1 is held, the shape of the body of collecting bottle 2 can be cylinder, and the shape of holding rod 1 can be cylinder, Collecting bottle 2 is selected from one of plastic bottle, vial etc., and the bottleneck of collecting bottle 2 is equipped with the first external screw thread 9,3 He of thief rod The threaded connection of corresponding cooperation is formed between the collecting bottle 2.Outside thief rod 3 with nut 5 and the first of 2 bottleneck of collecting bottle Screw thread 9 is connected through a screw thread to fix collecting bottle 2, realizes that water sampling is integrated with bottling, while passing through after sampling Turn internal and external threads separate thief rod 3 and collecting bottle 2.

The connecting pin of thief rod 3 is proximate to one end of armed lever 4, and the connecting pin of thief rod 3 is equipped with the first internal screw thread 6, armed lever 4 Connecting pin be proximate to one end of thief rod 3, the connecting pin of armed lever 4 is equipped with the second external screw thread 7, the connecting pin of thief rod 3 and arm The threaded connection of corresponding cooperation is formed between the connecting pin of bar 4.Armed lever 4 includes the sequentially connected sub- armed lever of multiple head and the tail, respectively One end of sub- armed lever is equipped with internal screw thread, and the other end is equipped with external screw thread, show in armed lever for example, with reference to Fig. 3, Fig. 3 near adopting The sub- armed lever of sample bar side, in figure, the external screw thread 7 of shown sub- armed lever is threadedly coupled with the connecting pin of thief rod 3, and the of sub- armed lever Two internal screw threads 8 are threadedly coupled with another sub- armed lever, and the threaded connection of corresponding cooperation is formed between adjacent sub- armed lever.Each sub- armed lever Length range is 1m-2m, preferably 1.5m, and each sub- armed lever length can be designed to equal length or different length, due to each son Armed lever can be detachably connected by screw thread, and when use can be according to the size depth in pond to be sampled come flexible modulation holding rod 1 Length.Armed lever 4 is selected from PVC bar, and PVC bar can be solid hopkinson bar.

As shown in Figure 1-3, the water sampler working principle of the present embodiment are as follows:

According to the size depth in pond to be sampled, by selecting the armed lever 4 of different length and quantity to adjust holding rod 1 Length.When water sampling, holding rod 1 is held, thief rod 3 is connected with collecting bottle 2, thief rod 3 drives collecting bottle 2 to be moved to Water sampling is carried out in water, is finished to water sampling, and thief rod 3 drives collecting bottle 2 to leave the water surface, due to thief rod 3 and acquisition Bottle 2 is detachably connected, and the separation of thief rod 3 Yu collecting bottle 2 may be implemented, collecting bottle 2 is backed out after water sampling, screws on bottle cap, Complete the acquisition of a water sample.

In conclusion the water sampler of the present embodiment, the bottleneck by the sampling end and collecting bottle 2 of thief rod 3 is removable Connection is unloaded, realizes that water sampling is integrated with bottling；Each sub- armed lever length can be designed to equal length or different length, Since each sub- armed lever can be detachably connected by screw thread, when use, can be according to the size depth in pond to be sampled come flexible modulation The length of holding rod 1.Compared with existing water sampler, have that structure is simple, is easy to make, low cost, energy easy to operate The integration for enough realizing water sampling, reduces the labor intensity of sample collector, the advantages that improving labor efficiency.

The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
