Multifunctional rock core box

Abstract

The invention discloses a multifunctional rock core box. The rock core box comprises a rock core box body, a box cover, a separation assembly, an air inlet and outlet unit and a driving assembly; thebox cover covers the upper opening of the rock core box body in a sealing manner; the separation assembly is arranged in the rock core box body and divides the rock core box body into multiple storagecavities; the air inlet and outlet unit is arranged on the box cover or the rock core box body and is used for vacuumizing the storage space; and the driving assembly is arranged at the bottom of therock core box body and drives rock cores to rotate in the storage cavities, so that the rock cores can be observed conveniently. The rock core box has the advantages that the box cover and the rock core box body are connected in the sealed mode, and the rock cores can be prevented from being exposed in the air; meanwhile, the air inlet and outlet unit communicates with the storage space defined by the rock core box body and the box cover, and negative pressure can be extracted through the air inlet and outlet unit, so that the rock cores are stored in the vacuum state and are prevented from making contact with the air, the storage time of the rock cores is further prolonged, the weathering phenomenon of the rock cores during long-term storage is effectively avoided, and the integrity of the rock cores is improved.

Description

technical field [0001] The invention relates to a core box, in particular to a multifunctional core box. Background technique [0002] A core box is a container for storing cores taken out by drilling. In geological surveys such as hydrology and mining, the cores taken out of the borehole are placed in the core box in sequence, and they are kept as important geological archives for a long time. When conducting research on mine exploration, deep resources or engineering geological conditions Provide accurate and reliable information. [0003] Existing rock core box great majority is the exposed casing that materials such as plastics and timber are processed, is convenient to observe and place rock core. However, the existing open core box makes the core always exposed to the air during long-term sample storage, and is easily affected by the external air to cause weathering, especially for rocks such as argillaceous sandstone and mudstone with poor hydraulic properties.

AI Technical Summary

Problems solved by technology

However, the existing open core box makes the core always exposed to the air during long-term sample storage, and is susceptible to weathering due to the influence of external air, especially for rocks such as argillaceous sandstone and mudstone with poor hydraulic properties. After the core is exposed for a period of time, it often disintegrates, which affects the detection of the core; in addition, measuring tools such as tape measure or ruler are needed to measure the length every time during the detection, which is inconvenient to operate
