Ice core clamp groove

Abstract

The invention relates to an ice core clamp groove, which comprises a bottom plate, a fixed right-angle bent plate, a movable right-angle bent plate, press plate screws, a silica gel pad plate and compression springs, wherein the clamp groove is in a concave shape, and consists of the bottom plate, the fixed right-angle bent plate and the movable right-angle bent plate; moving holes are formed in the bottom plate; the fixed right-angle bent plate is fixed on the bottom plate by 1# press plate screws; 2# press plate screws pass through the cylindrical spiral compression springs for fixing the movable right-angle bent plate in the moving holes of the bottom plate; the silica gel pad plate is adhered at the inner sides of the fixed right-angle bent plate and the movable right-angle bent plate. The ice core clamp groove has the advantages that the design is reasonable; the structure is simple; an ice core can be effectively fixed; the ice core is prevented from sliding and rotating in the process of pretreatment such as horizontal cutting; the horizontal fixing position is maintained; ice core precise cutting, ice core sample separation and accurate conductivity measurement are realized.

Description

technical field [0001] The invention relates to an ice core holding slot, in particular to a device for placing the ice core in the holding slot for fixing when the ice core sample is pretreated. Background technique [0002] An ice core is a cylinder of ice drilled from the surface of a glacier from top to bottom using an ice core drill. According to research needs, each section of ice core must first be divided into secondary ice cores of different shapes and sizes by horizontal band saw and vertical band saw, and then the secondary ice cores are further subjected to physical parameter observation, electrical conductivity measurement, marking, cutting, Arrangement, packaging and decontamination and other pre-treatments. In the process of horizontal cutting with the horizontal band saw, the horizontal cutting of the ice core is mainly achieved by the horizontal movement of the horizontal band saw along the guide rail. Because the ice core is a cylinder, and the horizont...

AI Technical Summary

Problems solved by technology

Because the ice core is a cylinder, and the horizontal band saw has a greater impact on the ice core during the cutting process, the ice core is prone to slip and rotate, which affects the accuracy of the horizontal cutting of the ice core and the accuracy of the ice core sampling. , so the ice core must be effectively fixed
