Claim 0:
1. A drilling fluid channel structure of a core drilling rig, comprising a fluid channel activation module, a pressure relief module, a flow diverging and blocking module, a driving fluid channel, and a cooling fluid channel,
wherein the fluid channel activation module, the pressure relief module, the flow diverging, and the blocking module are connected sequentially from a first end to a second end of the structure,
the driving fluid channel and the cooling fluid channel are connected at a rear side thereof to the flow diverging and blocking module,
wherein the driving fluid channel comprises a driving section and a driving fluid outlet, the driving section being disposed between a stator and a rotor of a driving motor, while the driving fluid outlet being disposed in front of the driving section, and
the cooling fluid channel extends through a layer disposed between an integrity-preserving compartment and an outer barrel, and
wherein a front end of the outer barrel is connected to a drill bit, and a front opening of the cooling fluid channel is located at the drill bit.
