Abstract

The invention discloses a device and method for collecting and storing microorganisms in frozen soil. The cantilever is released, the cantilever moves downward under weight, the drilling assembly drills the well and breaks the soil vertically, and the frozen soil isolation assembly and the drilling assembly move down synchronously to break the drilling assembly. Frozen soil isolation prevents cross-contamination; the drilling assembly moves down to the deepest position and stops rotating, connects the frozen soil isolation assembly with the power assembly of the drilling assembly, uses the rotating crankshaft of the drilling assembly to drive the rotation of the frozen soil isolation assembly, and uses the power assembly to drive the frozen soil isolation assembly The frozen soil storage point on the frozen soil is opened; the power assembly of the drilling assembly is stopped from rotating, and during the inertial rotation of the frozen soil isolation assembly, the power assembly drives the frozen soil storage point on the frozen soil isolation assembly to close; the cantilever is lifted to drive the drilling assembly and The frozen soil isolation components move up synchronously to complete the collection and induction of frozen soil; the invention realizes the collection and storage of frozen soil and its internal microorganisms during the drilling and crushing of frozen soil, improves efficiency and avoids cross-contamination of frozen soil microorganisms.

Description

technical field

[0001] The invention relates to the technical field of frozen soil microorganism collection, in particular to a frozen soil microorganism collection and storage device and method. Background technique

[0002] Frozen soil refers to various rocks and soils that are below zero degrees Celsius and contain ice. Generally, it can be divided into short-term frozen soil (hours / days or even half a month) / seasonal frozen soil (half months to several months) and permafrost (also known as permafrost, which refers to freezing that lasts for two or more years) Due to its unique geographical and climatic characteristics, frozen soil contains a large number of biologically active microorganisms in various forms and ecological groups, and has survived for thousands of years or even millions of years. The genetic characteristics and physiological and biochemical mechanisms of adaptation to the environment. Carrying out research on permafrost microorganisms will help protect ...

Embodiment Construction

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] like figure 1 As shown, the present invention provides a permafrost microorganism collection and storage device. This embodiment realizes the collection and storage of permafrost and its internal microorganisms in the process of permafrost drilling and crushing, thereby realizing multi-functional integration. On the one hand, the frozen soil is broken and isolated, and on the other hand, the frozen soil is collected from the d...
