Problems solved by technology

In addition, the existing magnetic fluid thrusters can only operate in conductive fluid (seawater), and cannot operate in inland rivers. Since fresh water is almost non-conductive, there is no basic condition for electromagnetic fluid propulsion. Therefore, the existing superconducting magnetic fluid Thrusters have certain limitations

Abstract

This invention relates to a superconduct magnetic liquids ship pushing device, which comprises the superconduct screw tube magnet and rotary magnetic liquids pushing channel, wherein, the superconduct screw tube magnet generates the even axle magnetic field in its central working area. There is located with one round metal electrode in the working round pipe of the magnetic liquids and with the round pipe metal outer cylinder as another electrode. There is a screw flow guiding pads between the metal outer electrode and central round electrode. There are distributed with several radial metal conductive bars and current control parts in the length direction of the screw guiding pad, which are connected to the above two electrodes through the conductive bars.

Description

technical field [0001] The invention relates to a ship propeller, in particular to a superconducting magnetic fluid ship propulsion device. Background technique [0002] Superconducting magnetic fluid ship propulsion is a new ship propulsion method. It uses seawater as a conductor. Under the action of an external electric field and magnetic field, the seawater is subjected to electromagnetic force to generate water jet propulsion through the channel and tail nozzle. Due to the cancellation of conventional propeller shafting and reduction gears and other mechanisms, noise and vibration can be greatly reduced, and it is possible to truly achieve "quiet" and high-speed ship propulsion. In the past ten years, with the development of superconducting technology, superconducting magnetic fluid ship propulsion technology has attracted more and more attention from all over the world. Japan, the United States, Russia and my country have all invested a lot of money in research in this ...
