Geophysical exploration collector

Abstract

The invention relates to the field of water bottom soil acquisition, in particular to a geophysical exploration acquisition device which has double functions of acquiring water bottom soil at different depths in the vertical direction and acquiring water bottom soil at different points in the horizontal direction, and the double functions can be synchronously realized. Meanwhile, on the basis that the downward moving depth of the horizontal collecting part is adjusted through the moving part, the downward moving depth of the horizontal collecting part can be adjusted, so that the diversity of collected soil samples of different horizontal layers is further improved, the single collecting pipes are connected in a movable assembly mode, and the collecting efficiency is improved. In this way, the assembling number of the collecting pipes, namely the overall length of the collecting pipes, can be controlled, then the maximum collecting depth of the vertical collecting part is in a variable state, the vertical collecting part can be suitable for collecting soil of different water areas or soil of different thicknesses in the same water area, and the application range of the collecting unit is widened.

Description

technical field [0001] The invention relates to the field of underwater soil quality collection, in particular to a geophysical prospecting and collecting device. Background technique [0002] The sediments of water ecosystems such as lakes and rivers are rich in microbial resources, and play a very important role in the maintenance of biogeochemical cycles and biodiversity. When collecting bottom soil, it is necessary to consider the depth of collection and the distribution of collection points according to the water conditions. For the depth of collection, when the collection depth is too shallow and there are few collection points, the diversity of the samples will be low, and the collected samples cannot be compared. It comprehensively reflects the real situation of the water area, and at the same time, if the collection depth is always kept the same, it is easier to reduce the accuracy of the situation reflected by different collection points in the same water area or d...

Problems solved by technology

[0002] The sediments of water ecosystems such as lakes and rivers are rich in microbial resources, which play a very important role in the maintenance of biogeochemical cycles and biodiversity. Often, sediments such as underwater soil are collected to reflect the real situation of sampling water points. When collecting underwater soil, it is necessary to consider the depth of collection and the distribution of collection points according to the water area. For the collection depth, when the collection depth is too shallow and there are few collection points, the diversity of samples is likely to be low, and the collected samples cannot be compared. Fully reflect the real situation of the water area, and if the collection depth is kept consistent, it is easier to reduce the accuracy of the situation reflected by different collection points in the same water area or collection points in different water areas

[0003] In addition, the effect of collecting soil at different depths to reflect the water area is not good enough. The soil at different depths only reflects the situation of the soil straight section layer, and the situation of the soil horizontal section layer will also reflect the real situation of the water area.
