Description

Ice core slot

technical field

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

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 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. In addition, in the process of measuring the conductivity of the ice core, it is also necessary to fix the ice core horizontally, so as to ensure the accuracy of the measurement results.

Contents of the invention

In view of the above, the purpose of the present invention is to provide an ice core holder, which has a reasonable design and a simple structure, can effectively fix the ice core, prevent the ice core from sliding and rotating during the horizontal cutting process, and keep it horizontally fixed Position, to achieve the precise cutting of ice core and the accuracy of ice core sampling and conductivity measurement.

The purpose of the present invention is achieved like this:

An ice core slot includes a base plate, a fixed right-angle bent plate, a movable right-angle bent plate, a pressing plate screw, a silicone pad and a compression spring. The card slot is concave, which is composed of a base plate, a fixed right-angle bend plate and a movable right-angle bend plate. There are movable holes on the base plate. The fixed right-angle bend plate is fixed on the base plate by 1# pressure plate screws, and 2# pressure plate screws pass through the cylindrical The helical compression spring fixes the movable right-angle bent plate in the movable hole of the bottom plate, and the inner side of the fixed right-angle bent plate and the movable right-angle bent plate is adhered with a silicone backing plate.

Advantage of the present invention and the beneficial effect that produce are:

1. The card slot is a concave groove design, one side is a fixed right-angle bending plate, and the other side is a movable right-angle bending plate. The ice core is placed between the fixed right-angle bending plate and the movable right-angle bending plate, and one side of the ice core is against the fixed right-angle bending plate. The bent plate remains stationary, and the other side rests against the inclined movable right-angled bent plate and relies on the elastic force exerted by the compression spring on the movable right-angled bent plate to act on the ice core to block and fix the ice core, effectively preventing the ice core from being stuck. Sliding and turning in the slot ensures that the horizontal position of the ice core in the slot remains unchanged.

2. The fixed right-angle bending plate is relatively stable, and its fixing effect is reliable. The inclined movable right-angle bending plate can adjust the distance between the fixed right-angle bending plate and the movable right-angle bending plate according to the change of the diameter of the ice core and exert horizontal and vertical effects on the ice core. The resultant force plays an obvious role in fixing.

3. The silicone backing plate is in direct contact with the ice core. On the one hand, it can increase the friction between the ice core and the card slot, and enhance the fixing effect of the card slot on the ice core; on the other hand, it can also play a buffer role to prevent right-angle bending. When the force on the ice core is too large, the ice core will be broken.

detailed description

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

As shown in Figure 1, an ice core slot includes a bottom plate 1, a fixed right-angle bent plate 2, a movable right-angle bent plate 3, 1# pressure plate screw 4, 2# pressure plate screw 4", a silicone backing plate 5 and a compression spring 6 The card slot is concave, which is composed of the bottom plate 1, the fixed right-angle bending plate 2 and the movable right-angle bending plate 3. There are movable holes on the bottom plate 1, and the fixed right-angle bending plate 2 is fixed on the bottom plate 1 by 1# pressure plate screw 4 2# pressure plate screw 4" passes through the cylindrical helical compression spring 6 to fix the movable right-angle bending plate 3 in the movable hole of the bottom plate 1, so that the movable right-angle bending plate 3 is inclined to the inner side of the groove, and the width of the groove is Slightly larger than the diameter of the ice core, and the depth of the groove is slightly larger than the radius of the ice core, so that the upper part of the ice core is exposed in the concave groove, which is beneficial to the horizontal cutting of the ice core and the measurement of electrical conductivity. A silicone backing plate 5 is adhered to the inside of the fixed right-angle bending plate 2 and the movable right-angle bending plate 3 . The silica gel backing plate 5 is in direct contact with the ice core. On the one hand, its function is to increase the friction between the ice core and the fixed right-angle bending plate 2 and the movable right-angle bending plate 3, and strengthen the fixing effect of the card slot on the ice core. On the other hand, it can It acts as a buffer to prevent the ice core from breaking when the right-angle bending plate exerts too much force on the ice core.

In actual operation, place the card slot horizontally and fix it on the surface of the workbench to prevent the ice core card slot from sliding. Before placing the ice core, straighten the inclined movable right-angle bending plate 3 with a clamp, increase the distance between the fixed right-angle bending plate 2 and the movable right-angle bending plate 3, so that the ice core can be placed in the slot, and then release it gently fixture. One side of the ice core rests against the fixed right-angle bent plate 2 to keep still, and the inclined movable right-angle bent plate 3 applies force to the ice core in the slot under the elastic force of the compression spring 6 to fix the ice core. If a single ice core is long or more than two ice cores need to be processed at the same time, two or more ice core slots can be connected end to end and fixed on the workbench. When the horizontal position of the ice core in the slot needs to be raised to meet the cutting depth of the horizontal band saw, a backing plate of a certain height can be placed at the bottom of the slot to raise the horizontal position of the ice core. After the processing of the ice core is completed, the movable right-angle bending plate 3 is also straightened by a jig so as to remove its force on the ice core, and the ice core is taken out from the slot.
