本発明は超電導磁石で海中に磁界を発生させな
がら通電して電磁力により推進する舶用電磁推進
装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an electromagnetic propulsion system for ships that uses superconducting magnets to generate a magnetic field in the sea while energizing the ship to propel the ship by electromagnetic force.

がために多量の磁束が外部に漏洩し、これが問題
視されることがあるという欠点を有している。 Previously, we proposed an electromagnetic propulsion system for ships that uses superconducting magnets (Japanese Patent Application Laid-open No. 102592/1983). The propulsion device of this earlier application has an electromagnetic coil for generating a magnetic field loaded in a container filled with liquid helium, and the helium container is housed in a vacuum container, and electrodes that energize underwater in the magnetic field are installed. It is set outside the vacuum container. According to this, it is possible to obtain a marine electromagnetic propulsion system that can generate a strong magnetic field in the sea, reduce the amount of electricity supplied in the sea, consume low power, and pose no risk of causing pollution. However, according to the electromagnetic propulsion device of the previous application, there are at most two pairs of electrodes, so there is a natural limit to the propulsive force that can be obtained.Also, the magnetic path is an open loop, which causes a large amount of magnetic flux to be generated. It has the disadvantage that it may leak to the outside and this may be viewed as a problem.
本発明の目的は推進力が更に強力で、漏洩磁束
が非常に少ない舶用電磁推進装置を提供すること
にある。 An object of the present invention is to provide a marine electromagnetic propulsion device that has a stronger propulsive force and has very little leakage magnetic flux.

り本発明を詳細に説明する。 According to one embodiment of the present invention, a plurality of donut-shaped superconducting magnets are arranged at equal intervals on the entire circumference centered on one point, and a plane formed by the superconducting magnets is centered on the one point. Arrange them in a radial pattern. By arranging the superconducting magnets in this way, the magnetic field forms a circular closed magnetic path centered at the above point, and the internal magnetic flux density is almost uniform, making it possible to extremely reduce magnetic field leakage to the outside. . Furthermore, since the superconducting magnets are arranged in a circular manner, a high-strength structure for supporting the attractive force between single magnets can be easily obtained. By arranging a large number of electrode plates facing each other between the superconducting magnets, which conduct electricity into the sea within this magnetic field, propulsion can be achieved using extremely strong electromagnetic force. Hereinafter, the present invention will be explained in detail with reference to the drawings.

are donut-shaped and are arranged at equal intervals on the entire circumference centered on the 0 point, and each plane is arranged in a radial shape centered on the 0 point. According to the plurality of superconducting magnets, the direction 5 of the magnetic field is circular centered on the 0 point, and leakage of the magnetic field to the outside is extremely small. In the figure, each superconducting magnet is an ellipse, but it may also be a perfect circle. Reference numerals 6 and 7 designate outer and inner planar electrode plates, respectively, which are disposed facing each other between the superconducting magnets. Then, when a current is passed between the two electrode plates by a DC power source (not shown), the seawater between the two electrodes is moved backward by the Lorentz force (arrow 8 in Figure 3), and the reaction of this seawater movement causes the ship to move. This will give you a driving force.

Therefore, for example, i=1 [KA/m 2 ], B

1.26×10 6 [N], and with this level of propulsive force 30
A sailing speed of ~40 knots can be achieved.

よく、必ずしも閉磁場は円形である必要はない。 The illustrated embodiment is a case in which a plurality of superconducting magnets are arranged at equal intervals on the entire circumference with one point as the center to generate a circular closed magnetic field, but the point is that a plurality of superconducting magnets are arranged endlessly. It is sufficient to generate a closed magnetic field, and the closed magnetic field does not necessarily have to be circular.

Effects such as the ability to easily obtain a high-strength structure due to the suction force support between the materials are expected.
