The invention discloses an armored cable type electric mechanical impact rotary drilling tool for polar drilling. The armored cable type electric mechanical impact rotary drilling tool for polar drilling comprises a rock cuttings chamber, a water pump, a driving motor, a variable speed system, a mechanical impact system and a drill bit; the rock cuttings chamber is formed in the upper part of thewater pump, a liquid outlet of the rock cuttings chamber is in communication with a liquid inlet of the water pump, the driving motor is arranged on the lower part of the water pump, and the lower endof the driving motor is connected with the variable speed system, the water pump and the variable speed system are driven by the driving motor to work, the lower part of the variable speed system isconnected with the mechanical impact system, the variable speed system drives the mechanical impact system to work, the drill bit is assembled on the lower part of the mechanical impact system, and the drill bit is driven by the mechanical impact system to work. The armored cable type electric mechanical impact rotary drilling tool for polar drilling has the beneficial effects that on the basis ofrotary cutting of the drilling tool, impact drilling is added, and the risk of complex drilling accidents such as stuck drilling is reduced; and the drilling tool has the advantages of simple structure, reliable system, wide application range and high drilling efficiency, and can be used for drilling in various working conditions such as ice layers, ice rock interlayers and under-ice bedrock layers.
