The invention belongs to the field of ground stress measurement, and particularly relates to a rapid orientation device and method in a nearly horizontal drilling rock core hole, when the rapid orientation device in the nearly horizontal drilling rock core hole is used, when a cleaning nozzle is matched with a blowing device to clean the bottom of a drilled hole, absolute ethyl alcohol can be poured into a cylinder through a mounting hole in a front end cover, and the hole bottom of the drilled hole is cleaned; and after the hole bottom is cleaned by the absolute ethyl alcohol, the cleaning spray head can continuously blow air to clean the hole bottom and blow the air to enable the absolute ethyl alcohol to be quickly volatilized, so that the hole bottom can be quickly cleaned. Through the orientation mark and the three-dimensional electronic compass, rapid orientation of the rock core in the nearly horizontal drill hole can be achieved. According to the in-hole rapid orientation method for the nearly horizon
