Improved frozen soil layer isotope sampling equipment

Abstract

The invention discloses improved frozen soil layer isotope sampling equipment comprising an equipment base (1), two sliding rods (6) are arranged on the equipment base (1) in the vertical direction; agasoline drilling machine (7) is arranged between the two sliding rods (6); supporting sliding rods (8) are symmetrically arranged on the side wall of the gasoline drilling machine (7) and connectedwith the inner sides of the sliding rods (6), a driving main shaft (12) is arranged on the gasoline drilling machine (7), the lower end of the driving main shaft (12) is connected with a drill rod (2), and the lower end of the drill rod (2) is movably connected with a drill bit (3) or a sampling rod (4). According to the improved frozen soil layer isotope sampling equipment provided by the invention, the drill bit and the sampling rod can be replaced, isotope soil sample forming is guaranteed, the effect of protecting a collected sample is achieved, meanwhile, a sampling head is firmly connected, and slipping in the isotope sampling head can be avoided.

Description

technical field [0001] The invention relates to an improved permafrost isotope sampling device, which belongs to the technical field of isotope sampling. Background technique [0002] Isotope hydrology is a subject that applies isotope theory and methods to study hydrological problems. Since it was put forward in the late 1950s, isotope hydrology as an independent subject has been greatly developed, and its research and application fields have also been continuously expanded. Today, the theory of isotope hydrology has been widely used in many fields such as hydrology, water resources, water environment and geology, especially in the research of water vapor source, rainfall-runoff relationship, water resource evaluation in arid and semi-arid areas, groundwater recharge, climate change and water cycle. In the field, the application is particularly common. As the background information and premise basis of the above research fields, the acquisition and accurate reflection of ...

Problems solved by technology

[0003] At present, because the sampling target is buried several centimeters or tens of centimeters deep underground, traditional isotope samplers and mechanical isotope samplers are limited in adapting to isotope soils, especially when sampling in dry hard compaction or loose isotopes, isotope soil samples are difficult to form and easy to extract from Slipping in the isotope sampling head makes sampling difficult
