Description

AUV magnetic coupling vector propulsion unit suitable for ice hole distribution
Technical Field
The utility model belongs to ocean engineering technique and polar region detection field relate to an AUV magnetic coupling vector advancing device suitable for ice hole cloth is put.
Background
The two poles of the earth have ice floating areas and ice racks connecting the ocean and the polar ice cover. The detection and sampling of the ice environment, including the observation of the circulation of the ice ocean temperature salt, the detection of the ice ocean ecological environment, the sampling of the ice seawater and sediments and the like, are important means for researching the circulation of the ice ocean temperature salt and the interaction between the ice frame and the ocean, and have important scientific significance. At present, two main modes are used for detecting the environment under ice, firstly, the instrument equipment with a cable is placed in the ice through drilling holes in the ice surface, the instrument equipment distributed in the mode is limited to a very limited range under the ice detecting holes, and the large-range detection under ice cannot be carried out. The second is by an Autonomous Underwater Vehicle (AUV) which travels Underwater. In this manner the AUV is typically deployed and retrieved by chiseling through the ice layer and then in larger ice holes, but for thick ice layers it is necessary to deploy and retrieve in ice holes of limited diameter. For example, ice racks with a thickness of up to a kilometer in the Antarctic region are usually drilled by a polar region hot water drilling machine, and the diameter of the drilled ice holes is usually in the order of 35 cm-80 cm. Whereas a conventional AUV has protruding components outside its housing, such as an antenna, a tail rudder to steer the AUV, etc. These parts are easily damaged after colliding with the ice hole when the ice hole is laid, and thus the conventional AUV is not suitable for being laid through the ice hole.
Furthermore, conventional AUVs rely primarily on the interaction of the tail rudder, which is very inefficient and highly compromised in maneuverability when the vehicle is traveling at low speeds. The vector propulsion mode can improve the maneuverability of the AUV, and particularly can improve the steering performance at low speed. However, conventional rudder or vector propulsion methods rely on contacting dynamic seals to transfer torque or thrust from within the seal cavity to outside the seal cavity to effect steering. The magnetic coupling propeller disclosed in CN208723765U includes a cylinder, a front end cover and a rear end cover are fixed at two ends of the cylinder respectively; a servo motor is fixed between the rear end cover and the motor frame, and the impeller is connected to the front end cover in a penetrating way. The end part of a driving shaft of the servo motor is connected with an outer rotor, and a group of outer rotor permanent magnets are arranged on the inner wall of the outer rotor; the end part of an output shaft of the impeller is connected with an inner rotor, the inner rotor is provided with an inner sleeve shaft which is sleeved at the end part of the output shaft, and a group of inner rotor permanent magnets are respectively arranged on the inner sleeve shaft and the inner wall of the inner rotor; the number of the outer rotor permanent magnetic blocks is equal to that of each group of inner rotor permanent magnetic blocks; along the circumferential direction, two sides of each outer rotor permanent magnet are respectively provided with an inner rotor permanent magnet on the inner sleeve shaft and an inner rotor permanent magnet on the inner wall of the inner rotor; a coupling sleeve is sleeved inside the cylinder body and between the outer rotor and the inner rotor, the coupling sleeve is extruded on the motor frame by the front end cover from outside to inside, and magnetic coupling is formed between the inner rotor and the outer rotor through the coupling sleeve. The output torque of the servo motor is transmitted to the impeller, the output shaft of the impeller synchronously rotates along with the driving shaft of the servo motor, and finally the displacement propulsion and the posture adjustment of the propeller are realized by controlling the steering and the torque of the output shaft of the servo motor. In the contact type dynamic seal, a shaft and a static seal ring contact with each other under certain pre-pressure and move relatively, and friction power loss is inevitably caused due to friction between the shaft and the static seal ring. In addition, after the working time is long, the sealing ring is abraded, and the risk of water leakage exists.
