Ice core clamping groove

Abstract

The invention relates to an ice core clamping groove which comprises a bottom plate, a fixed right-angle bent plate, a movable right-angle bent plate, a pressing plate screw, a silica gel cushion plate and a compression spring. The clamping groove is in a concave shape and is composed of the bottom plate, the fixed right-angle bent plate and the movable right-angle bent plate, a movable hole is formed in the bottom plate, the fixed right-angle bent plate is fixed to the bottom plate through a first pressing plate screw, and a second pressing plate screw penetrates through a cylindrical spiral compression spring to fix the movable right-angle bent plate in the movable hole of the bottom plate. And the silica gel cushion plate is adhered to the inner sides of the fixed right-angle bent plate and the movable right-angle bent plate. The clamping groove is reasonable in design and simple in structure, the ice core can be effectively fixed, the ice core is prevented from sliding and rotating in the pretreatment process such as horizontal cutting, the horizontal fixed position is kept, and accurate cutting of the ice core and accuracy of ice core sample separation and conductivity measurement are achieved.

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 horizontal...

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
