Abstract: A simulation device for magnetic closing of flap valve is disclosed, which includes a worktable, a driving mechanism for driving the worktable to rotate, a valve seat, a magnetic valve cover movably connected with the valve seat, a first magnet for repelling the magnetic valve cover, a cylinder, a lifting equipment for driving the cylinder to rise and fall. When the cylinder is inserted into the valve seat driven by the lifting equipment, the cylinder prevents the closure of the magnetic valve cover. When the cylinder is out of contact with the magnetic valve cover driven by the lifting equipment, the magnetic valve cover is closed, and the worktable in the simulation device can rotate and turn over, so that the closing process of flap valve (valve seat and valve cover) in any direction of deep drilling coring under the action of magnetic force is simulated.

Abstract: A system and method for measuring rock volume change under microwave irradiation. The system includes a test cavity, a microwave control device, strain measurement devices, a measurement circuit, and a resistance strain gauge. The test cavity is of a sealed cavity structure, in which a rock specimen and the microwave control device are provided. The strain measurement device includes circumferential strain gauges and axial strain gauges, and is attached to the surface of the rock specimen. The measurement circuit is connected to the strain measurement devices by means of leads, and the resistance strain gauge. After microwaves emitted by the microwave control device act on the rock specimen, the plurality of circumferential strain gauges and the axial strain gauges collect data from the rock specimen, and the volume change of the rock specimen can be obtained in combination with the measurement circuit and the resistance strain gauge.

Abstract: A core barrel sealing structure includes a core barrel, a drilling machine outer barrel, a chain mail-type flap valve and a trigger mechanism. The flap valve includes a valve seat and a chain mail-type valve flap. The trigger mechanism includes a trigger inner barrel and a trigger block. The trigger block is arranged in a through hole in a sidewall of the trigger inner barrel, and an inner wall of the drilling machine outer barrel is provided with a recessed opening adapted to the trigger block. When the core barrel is located in the valve seat, the valve flap is opened by 90° and is located between the trigger inner barrel and the drilling machine outer barrel. When the core barrel is lifted upwards, the valve flap returns to a top face of the valve seat to make sealing contact with a sealing face of a valve opening.
