Description

A fixed-point multi-depth sandy beach sampling device and method for UAV sampling

Technical field

The invention belongs to the technical field of muddy beach drilling and sampling, and is specifically a fixed-point multi-depth sandy beach sampling device and method for unmanned aerial vehicle sampling.

Background technique

Silt and silt coasts are coasts composed of silt and silt with particle sizes less than 0.05 mm. The shoreline of this type of coast is relatively straight, the beach is wide, and the shore slope is extremely gentle. The tide plays a leading role in the formation and shaping of the shore slope. When studying the geological conditions of the silt and silt coast, sampling is required. Silty sand and silt coasts are inconvenient for manual sampling. The geology is relatively soft, which makes it easy for people to fall into the interior, making it difficult to move, making sampling difficult. Moreover, although the current drilling sampling equipment can move on the silt sand and silt surfaces for sampling, there is a problem when sampling. Sampling cannot be carried out for a long time, so the sampling points are relatively scattered, making it inconvenient to sample the same point at different depths. Although the current drilling equipment can sample the same point at different depths, the drilling equipment is all muddy. Construction in relatively hard places and the heavy weight of the equipment make it inconvenient to drill and sample on silty sandy and silty coasts, and it is not convenient to conduct sampling and research on the geology of different depths on silty sandy and silty coasts.
