Abstract

The invention relates to the technical field of geological exploration, in particular to a sampling device for detecting mountain structures used for laying petroleum pipelines. The technical problem to be solved is: when the drill pipe is drilled into the mountain body, the mountain body samples in the drill pipe cannot be separated from the mountain body, and the mountain body samples cannot be taken out from the drill hole when the drill pipe is lifted upwards. The technical solution of the present invention includes a first shell, a circular shell, a second circular plate, a trigger mechanism, and a cutting mechanism. The outer ring surface of the second circular plate is fixedly connected with the inner surface of the first shell, the trigger mechanism is arranged on the upper and lower sides of the second circular plate, and a cutting mechanism is arranged between the first shell and the circular shell. The invention avoids the downward movement of the first connecting rod under the extrusion force of the elastic member by setting the trigger mechanism, and prevents the mountain samples from sticking to the mountain by setting the cutting mechanism, so that the mountain samples cannot be taken out in the drill hole.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a sampling device for detecting mountain structures used for laying petroleum pipelines. Background technique [0002] When laying oil pipelines in the mountains, it is usually necessary to sample and test the mountain structure. Through the detection of the mountain structure samples, the seismic resistance of the mountain and the probability of natural disasters can be calculated through the test data, so as to avoid natural disasters such as landslides from causing damage to the oil pipeline. , to prevent waste of resources. [0003] Existing sampling devices usually use a drill barrel to drill down. When the drill barrel reaches a specified depth, the drill barrel is taken out of the borehole and the mountain samples are taken out of the drill barrel. However, the sampling depth of the general mountain structure is very deep. When the drill barrel is drilled i...
