1. An embedded bionic winch for sampling and exploration of a polar sub-glacial lake, applied to a probe, comprising: an actuating chamber (1), a motor chamber (2), a cable arranging chamber (5) and a cable (7); wherein
the actuating chamber (1), the motor chamber (2), and the cable arranging chamber (5) are disposed inside the probe, and are coaxially arranged in sequence along a center line of the probe toward a direction of a drilling end of the probe;
the actuating chamber (1) is equipped with a sheave assembly, to reduce lifting or descending load of the probe on the cable arranging chamber (5);
the cable arranging chamber (5) is equipped with a drum (51), and the drum (51) is used to pre-wind the cable (7);
the motor chamber (2) is used to provide powers for the sheave assembly of the actuating chamber (1) and the drum (51) of the cable arranging chamber (5), so as to retract and release the cable (7).
