STEERING DEVICE OF UNDERWATER VEHICLE

WIPO Patent Application WO/2017/016412

A1

A steering device of an underwater vehicle comprises a permanent magnet (1), a transmission mechanism (2), and a motor (3). The motor (3) drives the permanent magnet (1) to rotate around a shaft by means of the transmission mechanism (2). The rotating direction of the permanent magnet (1) is perpendicular to the direction of a magnetic pole of the permanent magnet (1). The steering device is fixed onto an underwater vehicle, the motor (3) drives the permanent magnet (1) to rotate to an appointed direction by means of the transmission mechanism (2), and the underwater vehicle is enabled to rotate by means of the torque action from an earth magnetic field on the permanent magnet (1). When the direction of the magnetic pole of the permanent magnet (1) is consistent with that of the earth magnetic field, the torque action from the earth magnetic field on the permanent magnet is zero, and the steering motion of the underwater vehicle stops. When a steering operation is executed on the underwater vehicle by means of the steering device, a steering control strategy is simplified, and the corresponding energy consumption is reduced.
