The mounting bottom plates 6 can carry the vertical plate 7 and the sampling bucket 10 and provide a stable mounting base for these components. Meanwhile, the mounting bottom plates 6 are connected with other components such as the limit clasp 5 and the second thimble assembly 9 to integrate all the components together and make the whole device an organic whole. The symmetrically distributed vertical plate 7 and limit screw 8 help to accurately fix and position the sampling bucket 10 at different layers during the disposable multilayer sampling process, ensuring that the sampling operation at each layer can be smoothly performed. The whole device can calculate the water sampling depth according to the water depth after measuring the water depth, perform disposable multilayer sampling, improve work efficiency, ensure that the water sample is from the same water body at the same time, and improve the scientificity and accuracy of data.
[0027] The number of the support plates 4 is set to four, and each two of them form a group. The four support plates 4 are symmetrically distributed around the scale rope 1. The number of the sampling buckets 10 can be increased according to the length of the rod. The first thimble assembly 3 and the second thimble assembly 9 are adjusted and limited in different positions and heights on the scale rope 1 by the limit clasp 5 and the limit screw 8.
