Problems solved by technology

[0004] However, during the sampling process of the sampling device, due to the toughness of the rock itself and the influence of the environment such as the pressure in the ocean, the buffer bracket is not very stable, which will affect the sampling efficiency to a certain extent

Abstract

The invention discloses a rock-soil sampling device with device stability for marine geological survey. The rock-soil sampling device comprises a top plate and a shell located at the bottom end of the top plate, symmetrically arranged side plates I are arranged on two sides of the bottom end of the top plate, and transversely arranged transverse blocks are respectively arranged on one sides, far away from each other, of the two groups of side plates I; a vertically-arranged barrel is arranged at the bottom end of the transverse block, a drill bit matched with the barrel is arranged at the bottom end of the barrel, and a first friction plate and a second friction plate are arranged on the two sides of the barrel in an opening mode respectively. The device has the beneficial effects that the device is stable, inclination and collision of the device caused by large fluctuation of return water flow are avoided, the device is more stable in the sampling process, the quality of sampled rock soil is improved, and the sampling process is ensured to be smoothly carried out; the sampling pipe is driven to extend through the electric telescopic rod, the servo motor enables the sampling pipe to rotate, hard rock on the seabed can be rapidly sampled, the sampling pipe is detachable, and a sampled sample can be conveniently taken out.

Description

technical field [0001] The invention relates to the technical field of marine geological sampling, in particular to a rock soil sampling device for marine geological survey with a stable holding device. Background technique [0002] Marine geology and geophysics research is one of the most active fields in recent decades. In terms of basic theory, the birth of the modern plate tectonic theory largely depends on the breakthroughs made in marine geology and geophysics research. In the past decade or so after the 21st century, the international marine geology community has focused on the issue of "global change", exploring the geological period before human activities, or the change cycle and development trend of the earth's natural environment in the universe, and revealing the earth system. In the long process of geological evolution, the internal feedback mechanism and interaction between the hydrosphere and other spheres predict the future environmental change trend of the ...
