Abstract: A real-time temperature-pressure detection and rapid processing system for a calibration platform, comprises an inner return pipe, and a water supply pipe is provided therein with an inner water supply pipe. An outer wall of the inner water supply pipe is connected with an inner wall of the water supply pipe through multiple springs. An outer wall of the inner return pipe is connected with an inner wall of a return pipe through multiple springs. The return pipe and the water supply pipe are made of a thermosetting polymer material. The multiple springs, the inner water supply pipe, and the inner return pipe are covered with a heat conducting material. The system further includes a temperature-pressure detection assembly. The assembly includes multiple infrared sensors arranged at two sides of the return pipe and the water supply pipe, a booster pump, a heater, and infrared sensors connected with a control unit.

Abstract: An assembly method for a deep in-situ high-fidelity coring calibration platform includes the following steps: S1: fixing a core bin assembly subsystem on a preset ground foundation and fixing a simulator of a core bin on a mounting base plate of the core bin assembly subsystem; S2: driving a cylinder and driving the mounting base plate to move to a preset position; S3: driving a servo motor and controlling two clips to move close to each other; S4: fixing a drill pipe bin assembly subsystem on the ground foundation; S5: assembling multiple sections of a drill pipe bin in turn; aligning and connecting a bottom of the drill pipe bin to the simulator, and aligning and communicating the top of the drill pipe bin with the lower part of an adaptive drill pipe guide structure; and S6: driving the adaptive drill pipe guide structure to perform accurate positioning.

Abstract: A drilling control mechanism of a core drilling rig has a tooth drill and a core drilling rig. The core drilling rig is inside the tooth drill and engages with the drill in a sliding manner. A locking recess is formed at an inner wall of the tooth drill. A locking latch recess is formed at an outer wall of the core drilling rig and has a locking latch therein. The locking latch has a spring. When the locking recess is directly opposite the locking latch recess, the spring extends and the locking latch partially enters the locking recess. The core drilling rig has a central rod, a fluid channel activation module, an outer barrel, and outer barrel unlocking module and a flow diverging module. The central rod passes through the inner cavities of the fluid channel activation module, the outer barrel unlocking module and the flow diverging module.

Abstract: A control mechanism of a core drilling rig includes a central rod (14) and an outer barrel (23). The central rod (14) passes through, from the rear to the front, the inner cavities of a fluid channel activation module, an outer barrel unlocking module, a flow diverging module, and a coring barrel connecting module. The coring barrel connecting module comprises a core tube connecting pipe (62), a core ring bearing (63), a bearing inner ring (64), a ball A (6211) and a ball B (6411). The core tube connecting pipe (62) is connected at the front side thereof to the coring barrel (65). The bearing inner ring (64) is inside the core tube connecting pipe (62). The core ring bearing (63) is connected to an inner wall of the outer barrel (23).
