Description

Technical Field

[0001] The utility model relates to the technical field of geological disaster prevention research, in particular to a crack sampling device for geological disaster prevention research. Background Art

[0002] The crack sampling device used in geological disaster prevention research can effectively take geological samples at cracks and properly preserve the samples for subsequent research and analysis, further providing an important reference basis for geological disaster prevention research and helping to deeply explore the formation mechanism and influencing factors of geological disasters.

[0003] In the existing technology, during the sampling process, a tool is used to hammer the hammer seats on both sides of the device, so that the sampling head is gradually hammered into the soil layer, and during the hammering process, the sample to be taken will be left in the sampling gap, and then the sampling head is reset by the spring provided on the outside, and then the sampling head is manually removed to take the sample out of the outside of the sampling head, thereby completing the sampling work. However, in actual use, when the device faces a relatively hard geological soil layer, and the hammer seat is directly struck by humans with the help of a tool, the sampling head is made to enter the soil layer, which consumes more manpower during sampling, reduces work efficiency, and increases the labor intensity of the operator. When facing a deep and hard soil layer, the pressure applied during sampling is insufficient, making it difficult to effectively obtain deep crack samples, affecting the depth and accuracy of sampling. Therefore, it is necessary to improve a crack sampling device for geological disaster prevention research. Utility Model Content

[0006] The downward pressure-saving mechanism includes a downward pressure component and a labor-saving component, and the labor-saving component is arranged on the right side of the downward pressure component;

[0007] The downward pressure assembly includes a connecting sleeve, which is fixedly connected to the top of the device body, and a slider is fixedly connected to the bottom of the connecting sleeve.

[0011] Preferably, through holes are provided at corresponding positions of the clamping column and the limiting sleeve, and the clamping column is inserted into the through hole, and the limiting strip is slidably connected to the inside of the limiting sleeve, so that the staff can easily press down the sampling tube.

[0013] Preferably, grooves are provided at positions of the inclined block corresponding to the sampling sleeve, and the inclined block is inserted into the grooves to facilitate quick fixation of the sampling sleeve.

[0014] Compared with the existing technology, the present invention provides a crack sampling device for geological disaster prevention research, which has the following beneficial effects:

[0015] 1. The crack sampling device for geological disaster prevention research has a downward pressure-saving mechanism. During use, the sampling tube can be inserted deep into the crack by manually pulling down the limit column. In addition, the labor-saving component based on the lever principle can be used during the sampling process. Even when facing a harder soil layer, the staff can easily insert the sampling tube into the deep soil layer to complete the sampling work. The downward pressure is in a vertical state through the connecting rod and the guide column, thereby achieving self-locking, thereby achieving a pressure multiplication effect, reducing the labor intensity of the operator, and avoiding insufficient pressure applied during sampling.
