BUILT-IN BIONIC WINCH FOR SAMPLING AND DETECTION OF ANTARCTIC SUBGLACIAL LAKES

摘要

A built-in bionic winch for the sampling and detection of Antarctic subglacial lakes, comprising an actuation cabin (1), a power cabin (2), a transition cabin (3), a sensor cabin (4), a rope cabin (5) and a slip ring cabin (6); the actuation cabin (1), the power cabin (2), the transition cabin (3), the sensor cabin (4), the rope cabin (5) and the slip ring cabin (6) are sequentially arranged and are coaxially connected to one another by using a detachable means. The power cabin (2) provides power for the entire winch and can achieve in a certain depth of water the sealing of a motor located at the interior of same; the transition cabin (3) and the sensor cabin (4) are the transition of the entire winch and the portions in which tension sensors (43) are installed; the rope cabin (5) enables a cable (7) after force reduction to retract by means of the precise cooperation between a reel (51) and a lead screw (55); a slip ring (64) is comprised within the slip ring cabin (6), which ensures that a joint portion of the cable (7) is relatively stationary when the reel (51) rotates and winds the cable (7), so as to protect a cable joint. The built-in bionic winch is a slender built-in bionic winch that can be applied to an Antarctic subglacial environment and that is pollution-free, has a small volume, and a large load.
