Electromagnetic fluid surface vectored thruster and underwater device adopting thruster

Abstract

The invention discloses an electromagnetic fluid surface vectored thruster and an underwater device adopting the thruster. The electromagnetic fluid surface vectored thruster comprises excitation devices, surface electrodes, insulating non-magnetic-conductive bases, electrode switches, wires and a power supply. The excitation devices and the surface electrodes are distributed on the surface of the electromagnetic fluid thruster in a two-dimensional array mode. The magnetic field directions of the excitation devices are perpendicular to the surface of the thruster, and the magnetic field directions of every two adjacent excitation devices are opposite. Each surface electrode is arranged between every two corresponding excitation devices. Each surface electrode is connected with the power supply through the corresponding switch. Each electrode switch has three work statuses of being connected with a power supply positive pole, connected with a power supply negative pole and turned off, and each electrode switch can only be in one of the three work statuses at the same moment. Each surface electrode can work in one of the three work statuses of being disconnected from the power supply, connected with the power supply positive pole and connected with the power supply negative pole. Every two surface electrodes can work independently. The thruster has vectored thrust, can achieve thrust in any direction, and achieves actions of transverse movement, rolling around the axis and in-situ rotation accordingly, and the movement flexibility of the underwater device is greatly improved.

Description

Technical field [0001] The invention belongs to the field of underwater propulsion power, and relates to a two-dimensional cross-array electromagnetic fluid surface vector thruster and an underwater device using the thruster. It is suitable for any excitation mode, any underwater device surface shape, any excitation device and Two-dimensional cross-array electromagnetic fluid surface vector thruster with the number of surface electrodes. Background technique [0002] In the field of navigation, propeller propellers have long been the main propulsion tools of ships. They have the characteristics of simple structure, flexible operation, good maneuverability, high propulsion power and high efficiency. However, the inherent defects due to its own structure have not been eliminated. The propeller and the transmission mechanism of the propeller are rigidly connected, which will inevitably produce vibration and noise during operation, and also generate bubbles at the tips of the propel...

Problems solved by technology

[0003] However, in the traditional electromagnetic fluid surface propulsion technology, the magnetic poles and electrodes of the excitation device are simply arranged, so the thrust direction generated is single, resulting in a single movement form of the underwater device, which limits the flexibility of movement
