Problems solved by technology
However, in actual operation, it is difficult for operators to determine the depth of the water layer, and it is difficult to accurately judge the depth of the sampling tube inserted into the soil layer only by the distance moved down from the sampling tube. The soil at a suitable depth can only be collected after the first test, and the sampling tube needs to be cleaned after each test, and the operation of underwater soil sampling is relatively cumbersome

The invention discloses an underwater soil sampling device. The underwater soil sampling device comprises a support device, an outer sleeve assembly, a sealing ring, a sampling tube, a driving assembly, a depth detection and drainage assembly and a plug pin, wherein the support device comprises a first support and a second support, and the second support is provided with a pointer and a first mounting cylinder; the outer sleeve assembly comprises an outer sleeve and a conical head, the outer sleeve is inserted into the first mounting cylinder, and a first rack is arranged on the outer side wall of the outer sleeve; the sampling tube is inserted into the outer sleeve assembly; the driving assembly comprises a rotating part and a first gear; the depth detection and drainage assembly comprises a feeler lever, a stop plate, a water pipe support, a first water suction pipe and a water pump, the feeler lever is located on the outer side of the outer sleeve assembly and arranged on the secondsupport in an up-down sliding mode, scales are arranged on the feeler lever, the first water suction pipe is located in the sampling tube, and the first water suction pipe is connected with the waterpipe support. When the sampling tube is inserted into an underwater soil layer, the depth of the sampling tube inserted into the soil layer can be determined through the scale value indicated by thepointer, and the sampling operation of an operator is simplified.
Description
technical field [0001] The invention relates to the technical field of soil sampling equipment, in particular to an underwater soil sampling device. Background technique [0002] At present, in order to analyze some parameters of the soil (such as the metal content of the soil, the degree of fertility, and the degree of pollution, etc.), it is necessary to sample the soil. In some cases, however, it is desirable to sample the soil located under water. A common soil sampling method is to insert a hollow sampling tube into the soil after passing through the water layer, and then pull out the sampling tube upwards, and the soil sample can be retained in the inner cavity of the sampling tube. [0003] In general, it is necessary to collect soil at a certain depth. For underwater sampling, the distance that the sampling pipe moves down is approximately equal to the sum of the depth of the water layer and the depth of soil sampling. However, in actual operation, it is difficult ...
