Technical Field

Background
The ocean resources in China are rich, and the ocean resources are a huge natural resource treasury. The exploration and development of marine resources is urgent. Autonomous underwater robots (Autonomous Underwater Vehicle, AUV) are an important tool for the investigation and development of marine resources, with many military and civilian uses. In order to keep the aircraft sailing forward at a certain speed in the water, a certain thrust must be supplied to overcome the resistance it encounters. Devices or mechanisms that convert power from an energy source to power for the forward motion of a pusher are collectively referred to as underwater propulsors.
The underwater propeller industry has great technical difficulty and great market potential, the technical research and development of China in the industry is in a relatively lagging state, and most of the underwater propellers with balanced torque used in the international current stage are counter-rotating propellers.
The propeller is used as a driving device most commonly used for an underwater robot, and the dynamic sealing problem of the propeller is difficult to solve. At present, the common method for solving the problem of dynamic sealing of a propeller is mechanical sealing, namely, a Gelai ring, an oil seal or a rubber sealing ring is used on a transmission shaft of a propeller, but the mechanical sealing has large friction resistance and low transmission efficiency in the transmission process, and the transmission efficiency is influenced by sea water pressure. A method for solving the dynamic sealing problem of the propeller based on the magnetic coupling principle is also intensively studied. The basic principle is that a plurality of permanent magnets are respectively embedded on a driving shaft (generally an output shaft of a motor) and a driven shaft (generally a propeller transmission shaft). Through reasonable arrangement, attractive force is generated between the two shafts, the two shafts are separated by a spacer, and the motor is guaranteed to be watertight. Thus, the driven shaft and the driving shaft can synchronously rotate by magnetic field force.

Assuming that the propeller 11 rotates clockwise, when the water flows through the wing-shaped front stator 24 and the wing-shaped fin plate 23, the pressure is not used due to different flow rates of two side surfaces of the asymmetrical wing, the side with high pressure can exert force on the side with low pressure, and the force generated by the 5 wing-shaped front stators 24 and the wing-shaped fin plates 23 which are coaxially and uniformly distributed can form stable clockwise torque which can effectively offset the force generated by the propeller 11 on the middle end 2 of the shell in the anticlockwise direction when the propeller rotates, so that the torque balance of the propeller in the water flow is realized.

In practical application, the hub cap fin 12 is connected with the propeller 11 through the long screw 13, the propeller 11 rotates in the clockwise positive direction, when the water flows through, hub vortex is generated at the propeller hub and a low pressure area is generated, the phenomenon can lead to the increase of the overall energy consumption of the propeller, and at the moment, the hub cap fin 12 connected at the rear of the propeller 11 can guide the part of fluid to counteract the existence of the low pressure hub vortex, so that the energy-saving effect is generated.
