The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0019] The utility model embodiment provides an adjustable sampler, such as Figure 1-4 As shown, it includes an outer shell upright 1, the outer wall of the upright 1 is respectively sleeved with a first ring 2 and a second ring 6, the outer wall of the upright 1 is provided with a guide groove, the inner walls of the first ring 2 and the second ring 6 are respectively fixedly connected with guide blocks matching the guide groove, and the upper surface of the first ring 2 is fixedly connected with a bottom plate 3, the upper surface of the bottom plate 3 is fixedly connected with a top block 5, and the outer wall of the first ring 2 is threadedly connected with a fastening bolt 4, the outer wall of the second ring 6 is fixedly connected with a sampling barrel 7, and the upper surface of the sampling barrel 7 is bolted with a connecting rope 8, the lower surface of the sampling barrel 7 is provided with a water inlet hole 9, and the inner wall of the sampling barrel 7 is hinged with a baffle 10, the baffle 10 is located above the water inlet hole 9, and the inner opening size of the water inlet hole 9 is larger than the outer opening size of the top block 5, the upright 1 includes a rod body 101, and the lower surface of the rod body 101 is fixedly connected with a threaded rod 102, and the upper surface of the rod body 101 is provided with a threaded groove 103 matching the threaded rod 102.
[0020] It should be noted that, since the existing samplers can only sample river and lake water sources of one depth during the sampling process, and the sampling height cannot be flexibly adjusted, the sampling range of the entire sampling tube is too limited. Therefore, in order to solve the problem that the existing samplers cannot flexibly adjust the sampling depth, during sampling in this scheme, the first ring 2 is inserted from the bottom of the vertical pole 1, and the personnel rotate the fastening bolt 4 to fasten the bottom plate 3 under the vertical pole 1. The personnel immerse the lower end of the vertical pole 1 into the water. The length of the vertical pole 1 can be adjusted by connecting multiple rod bodies 101 end to end to adjust the total length of the vertical pole 1. When the bottom plate 3 reaches the specified water depth, The upper end of the vertical pole 1 is inserted into the second ring 6, and the personnel tie the free end of the connecting rope 8. Under the influence of gravity, the sampling tube 7 falls downward from the upper end of the vertical pole 1 to the bottom plate 3. The sampling tube 7 contacts the bottom plate 3, which will cause the top block 5 to enter the water inlet hole 9. The top block 5 will squeeze the baffle 10, causing the baffle 10 to rotate upward, thereby opening the water inlet hole 9 and allowing water of a specified depth to enter the sampling tube 7. The personnel pull the free end of the connecting rope 8 to raise the sampling tube 7. The sampling tube 7 leaves the bottom plate 3, which will cause the top block 5 to come out of the water inlet hole 9. The baffle 10 is affected by gravity and re-seals the water inlet hole 9 to prevent water of other depths from entering the sampling tube 7, thereby ensuring the accuracy of sampling.
