Abstract: A drilling mechanism of a coring drilling rig has a central rod, a fluid channel starting module, an outer barrel, an outer barrel unlocking module, a shunting module and a drill bit. The central rod penetrates the fluid channel starting module. The outer barrel unlocking module and an inner cavity of the shunting module from back to front. The fluid channel starting module is behind the outer barrel and is connected to the outer barrel unlocking module. The shunting module is in front of the outer barrel unlocking module, and a hydraulic motor is connected in front of the shunting module. The outer barrel has a driving section that is a rotor of the hydraulic motor. The outer wall of the outer barrel is fixedly connected to a centralizer, and the front end of the outer barrel is connected to the drill bit.

Abstract: A drilling fluid channel structure of a core drilling rig includes a fluid channel activation module, a pressure relief module, a flow diverging and blocking module, a driving fluid channel and a cooling fluid channel. The fluid channel activation module, the pressure relief module and the flow diverging and blocking module are connected sequentially from the rear to the front. The driving fluid channel and the cooling fluid channel are connected at the rear side thereof to the flow diverging and blocking module. The driving fluid channel includes a driving section located between a stator and a rotor of a driving motor. The driving fluid channel is provided with a driving fluid outlet at the front side of the driving section. The cooling fluid channel passes through a layer disposed between an integrity-preserving compartment and an outer barrel.

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.

Abstract: A driving system for a core drilling rig has a driving motor. The driving motor has an outer rotor and an inner stator, and mutually-matched convex ribs are provided on the inner wall of the outer rotor and the outer wall of the inner stator. The outer rotor and the inner stator are in clearance fit. A clearance between the outer rotor and the inner stator is a driving liquid channel. The length of the outer rotor is less than that of the inner stator. The outer rotor is provided between the front and rear ends of the inner stator. The outer rotor is connected to an outer cylinder. The rear end of the inner stator is connected to a coupling.

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: An acoustic emission probe positioning system, a test block for the system, and an application of the system are disclosed. The positioning system comprises a first test block and a second test block that are oppositely arranged and that define a non-closed test region. The first test block includes a first main portion and a first protruding portion that are connected to each other. The second test block includes a second main portion and a second protruding portion that are connected to each other. The first main portion and the second main portion are vertically opposite to each other, and the first protruding portion and the second protruding portion are opposite to each other left and right in a staggered manner. Multiple first probe storage holes are defined in the first main portion, and multiple second probe storage holes are defined in the first protruding portion.
