A dry hole type thermal shock rotary coring drilling tool belongs to the field of drilling tools, the drilling tool comprises a drilling tool outer pipe, an electric shock device, an electric rotary device and a sampling device, the electric shock device, the electric rotary device and the sampling device are arranged in the drilling tool outer pipe, and the sampling device comprises a drilling tool inner pipe, a second slip ring, a miniature vacuum liquid pump, a melt water conveying pipe, a water storage pipe, an ice core cutter, a hot melting drill bit and an ice core pipe. Impact rotation and hot melting drilling are combined, pollution to an ice layer caused by using drilling fluid can be avoided, and drill jamming accidents occurring in a hole are effectively avoided. The impact drilling not only enables the ice layer at the bottom of the hole to generate micro cracks, but also can transmit the heat of the hot melting drill bit into the micro cracks in a pulse form, so that the strength and cutting resistance of the ice layer are reduced, and the drilling efficiency is improved. In the drilling process, the outer pipe of the drilling tool does not rotate, and friction between the outer wall of the drilling tool and an ice layer is avoided. The melt water conveying pipe and the water storage pipe are both heated through heating wires, blockage caused by melt water freezing is avoided, and meanwhile damage to the melt water conveying pipe and the water storage pipe caused by freezing and frost heaving is prevented.
