Description

Technical Field

[0001] This invention relates to a magnetically levitated rotary sail, and more particularly to a magnetically levitated rotary sail that can rotate by magnetic levitation without bearings. Background Technology

[0002] Recently, with the strengthening of regulatory requirements for greenhouse gas emissions from ships, technologies for reducing greenhouse gas emissions from ships, such as the application of renewable energy technologies like wind power, have received widespread attention.

[0003] Among them, the double-rotor sail, as a technology that uses wind power to assist the propulsion of ships, can significantly reduce carbon emissions generated during the use of fossil fuels on ships because it can assist the ship's propulsion power.

[0004] For example, the Magnus rotor disclosed in Korean Patent Registration No. 10-1488839, etc.

[0005] However, because the rotor and support in a Magnus rotor are connected by bearings, wear will occur in the bearings according to the rotor's rotation speed, leading to a decrease in durability, and periodic maintenance is required.

[0006] Therefore, people are trying to develop a device that can ensure the durability of the rotary sail and make it easy to maintain even when the rotation speed of the rotary sail is high, but so far no satisfactory results have been achieved.

[0011] To achieve the objectives described above, the present invention provides a magnetically levitated rotary sail, characterized in that it comprises: a coil portion disposed at the lower part of the main body; an electromagnet for levitizing the coil portion; a support member for supporting the electromagnet; and a gap sensor disposed at the support member for measuring the gap between the coil portion and the electromagnet.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the magnetic levitation rotary sail A, to which this invention is applicable, includes a main body 100, a coil part 200, an electromagnet 300, a support member 350, and a gap sensor 400.

[0033] The main body 100 of the present invention can rotate by means of wind power and obtain propulsion through the Magnus Effect.

[0034] At this time, as one embodiment of the main body 100, it can be a hollow cylindrical shape.

[0035] Among them, the main body 100 such Figure 2 As shown, the main body 100 can be secured to the hull 10 when needed by being equipped with locking component 105.

[0036] In this embodiment, hooks 110 may be provided on the main body 100 and the hull 10, and the main body 100 may be fixed by binding ropes 115 to the hooks 110.

[0037] The coil portion 200 of the present invention is provided on the lower part of the main body 100 and includes a suspension coil 210 and an electric coil 220.

[0038] The electromagnet 300 of the present invention can make the coil portion 220 levitate.

[0039] Specifically, the levitation coil 210 of the coil section 200 can be equipped with a vertical gap to the electromagnet 300, thereby levitizing the main body 100 in the vertical direction, and the coil 220 can be equipped with a horizontal gap to the electromagnet, thereby causing the main body 100 to rotate.

[0040] At this time, as an embodiment of the levitation coil 210, a repulsive type, such as an electromagnet 300, can be used, which is suspended by repulsive force due to its polarity.

[0041] Among them, electromagnet 300 and coil 220 are as follows Figure 3 As shown, when wind power is transmitted to the main body 100, the N pole a and S pole b of the electromagnet 300 can be rotated by using the N pole a and S pole b of the coil 220.

[0042] At this time, the electromagnet 300 can be magnetic when a power source is applied.

[0043] In another embodiment, an attraction method can be used, in which the levitation coil 210 is given opposite polarity by controlling the timing of the power supply applied to the opposing electromagnet 300 and is levitated by the attraction force of the adsorption.

[0044] At this time, the electromagnet 300 can be equipped with and supported by the support component 350.

[0045] The gap sensor 400 of the present invention can be equipped on the support member 350 and measure the gap between the coil part 200 and the electromagnet 300.

[0046] In one embodiment of the gap sensor 400, the gap between the levitation coil 210 of the coil section 200 and the electromagnet 300 can be measured and connected to a controller (not shown).

[0047] At this point, when the gap between the levitation coil 210 and the electromagnet 300 becomes smaller, the controller (not shown) can stop the operation of the electromagnet 300.

[0048] Since any general structure and form of controller (not shown) can be used as long as the electromagnet 300 can be controlled, detailed descriptions related to the controller (not shown) will be omitted.

[0049] In addition, by equipping the lower part of the main body 100 with a buffer component 150, collisions between the main body 100 and the support component 350 can be prevented when the gap becomes smaller due to problems with the suspension coil 210 and the electromagnet 300.

[0050] The magnetic levitation rotary sail A to which this invention is applied will be described in detail below.

[0051] The main body 100 of the present invention can be in the form of a hollow cylindrical structure, thereby rotating by wind power and obtaining propulsion through the Magnus Effect.

[0052] At this time, a locking component 105 can be provided on the main body 100 to secure the hull 10 when needed.

[0053] Hooks 110 can be installed on the main body 100 and the hull 10, and the main body 100 can be fixed by binding ropes 115 to the hooks 110.

[0054] The coil portion 200 of the present invention can be equipped at the lower part of the main body 100, and when power is applied to the electromagnet 300, the main body 100 can be suspended and rotated by means of wind.

[0055] At this time, the suspension coil 210 of the coil section 200 can be equipped with a vertical gap with the electromagnet 300, thereby suspending the main body 100 in the vertical direction, and the electric coil 220 can be equipped with a horizontal gap with the electromagnet, thereby causing the main body 100 to rotate.

[0056] The electromagnet 300 can be equipped with and supported by the support component 350.

[0057] In this way, if the coil 220 or electromagnet 300 malfunctions, damage or danger caused by collision between the main body 100 and the support member 350 can be prevented.

[0058] The gap sensor 400 can be equipped on the support member 350 to measure the gap between the coil part 200 and the electromagnet 300, and is connected to the controller (not shown).

[0059] At this time, when the gap between the levitation coil 210 and the electromagnet 300 becomes smaller, it can be detected by the gap sensor 400 and the controller (not shown) can stop the operation of the electromagnet 300.

[0060] In addition, by equipping the lower part of the main body 100 with a buffer component 150, collisions between the main body 100 and the support component 350 can be prevented when the gap becomes smaller due to problems with the suspension coil 210 and the electromagnet 300.

[0061] The invention described above is not limited to the embodiments described above, but can be modified without departing from the spirit of the invention as claimed in the claims, and such modifications are included within the scope of protection of the invention as defined by the appended claims.
