Abstract

The invention relates to a magnetic coupling steering device for an autonomous underwater vehicle (AUV) in deep sea, belongs to the field of underwater robot, and specifically relates to a rudder rotating device of the autonomous underwater vehicle (AUV). Disc type magnetic couplers are arranged inside and outside an autonomous underwater vehicle (AUV) cabin. The external magnetic coupler and a bearing block are embedded into the cabin body, one end of an outer rudder shaft is connected with the external magnetic coupler, the other end of the outer rudder shaft is connected with a rudder through a cylindrical pin, the outer rudder shaft is installed on the bearing block through the bearing, one end of an inner rudder shaft is connected with the internal magnetic coupler, and the other endof the inner rudder shaft is connected with a gear; the inner rudder shaft is arranged on an inner support via a bearing. According to the embodiment, a driving mechanism uses a transmission mechanismto drive the inner rudder shaft to rotate, and uses the disc type magnetic couplers to drive the outer rudder shaft and the rudder to rotate synchronously, thus realizing rotation control over the rudder of the deep sea autonomous underwater vehicle (AUV). The magnetic coupling steering device has the advantages of being good in sealing performance, small in appearance resistance, low in energy consumption, high in reliability and the like.

Description

technical field [0001] The invention belongs to the field of underwater robots, in particular to a magnetically coupled rudder steering device for a deep-sea autonomous vehicle, which is suitable for solving the sealing problem that occurs when the rudder plate of the deep-sea autonomous vehicle rotates. Background technique [0002] Autonomous underwater vehicle (AUV) is an important means of civilian fields such as marine scientific research, resource investigation, emergency search and rescue, etc. It also plays a key role in intelligence detection, mine detection and mine elimination, and military support. It is regarded as a modern naval force. multiplier. While autonomous underwater vehicle (AUV) technology is gradually maturing, new problems are constantly emerging. With the continuous increase of the underwater robot's diving depth, one of the key issues in the development of underwater robots has become the dynamic sealing of shaft parts. When the shaft is rotatin...
