[0021] (2) The extremely cold environment groundwater monitor with power management function, through the mutual cooperation between the friction column, the first vertical groove, the blades and the friction ring, the rotating rod drives the friction column and the blades to rotate during the rotation process, so that the friction column and the friction ring generate heat to heat the surrounding air, and at the same time, the heated air can be blown into each heat-conducting square tube through the horizontal cavity and the vertical cavity, and finally blown into the ice layer, so that the hot air and the ice layer can exchange heat, thereby improving the drilling efficiency of the drill bit.
