Deep rock in-situ active thermal-insulation coring device and thermal-insulation coring method thereof

A deep rock in-situ active thermal-insulation coring device comprising an in-situ coring system and an in-situ truth-preserving moving system, wherein the in-situ coring system comprises a driving module, a coring module and a thermal insulation module, and the in-situ truth-preserving moving system comprises a truth-preserving chamber storage module and a mechanical arm;

• the thermal insulation module comprises a coring truth-preserving chamber and a temperature regulation control system, the temperature regulation control system is integrated in the coring truth-preserving chamber, the truth-preserving chamber storage module comprises a storage truth-preserving chamber and a temperature balance control system, the temperature balance control system is integrated in the storage truth-preserving chamber, the mechanical arm is mounted in the storage truth-preserving chamber, and the coring truth-preserving chamber and the storage truth-preserving chamber are mutually butted;
• and
• the driving module drives the coring module to extract a rock core having a formation in-situ temperature, the coring module conveys the extracted rock core to the coring truth-preserving chamber, the temperature regulation control system monitors the formation in-situ temperature and regulates the temperature of the rock core in the coring truth-preserving chamber to be consistent with the formation in-situ temperature in a coring procedure, the temperature balance control system regulates an internal temperature of the storage truth-preserving chamber to be consistent with an internal temperature of the coring truth-preserving chamber, and the mechanical arm moves the rock core to the storage truth-preserving chamber.
