Description

Technical Field

[0001] This invention relates to the field of superconducting power generation technology, specifically to a superconducting turbine rotation-excited focusing flux power generation system and method. Background Technology

[0002] Currently available superconducting generators are all power generation systems designed based on the Faraday principle of electromagnetic induction. Their superconducting coils are fixed inside the generator, and the passive induction excitation coil cuts the superconducting coil to generate electricity. This traditional Faraday electromagnetic induction power generation principle is, in fact, a power generation system that generates magnetic flux by rotating the excitation coil. The rotation of the excitation coil's magnetic field is transmitted to the induction coil through the generated magnetic flux, resulting in power generation—an indirect excitation power generation mode. This type of generator is constrained by Lenz's law (the effect of rejection on the outgoing coil). Most of the kinetic energy of the prime mover driving the generator's excitation coil is used to rotate and cut the induction coil. Simultaneously, the induced magnetic field also generates a Lenz's law-dependent reaction force, with over 30% of the prime mover's energy used to overcome this reaction force, resulting in heat loss. Based on the superconducting zero-resistance effect, an alternating magnetic field can be generated using an AC coil wound around a superconducting coil. This superconducting coil can be designed as a self-sustaining internal circulation mode with externally controlled power supply. This can significantly reduce the power supply required to generate a strong magnetic field. The excitation coil inside the superconducting motor can also be designed as a self-sustaining internal circulation mode with externally controlled power supply, significantly reducing the power supply required for the superconducting motor.

[0003] In existing superconducting technologies, most research focuses solely on fundamental physical phenomena. Several invention patents related to superconductivity exist, but traditional superconducting generators rely on passive induction power generation using static coils, resulting in low magnetic flux utilization and complex cooling structures. Examples include US patent (US20150007431A1) and European patent (WO2021123456A1). Research on rotating superconductors is primarily for loss testing devices (Nagoya Univ.Tech.Rep.2015), and research on manufacturing magnetic levitation bearings, such as Japanese invention patent JP2015088254A, applicant: IHI Corporation. These patents merely utilize static magnetic flux pinning to achieve bearing functionality, without addressing active magnetic flux control and power generation applications.

[0004] However, several experiments involving superconducting rotation provide definitive evidence for the factual basis of the innovative implementation of this invention: the first study is the theoretical study of magnetic flux motion inside superconductors (CPBean, Phys. Rev. Lett. 1962) - experiments on moving superconductors; and another (YBKim et al. Phys. Rev. 1963), which studies the peak loss caused by magnetic flux pinning when the superconducting rotor rotates.

[0005] In particular, the third research experiment is a result of research from the Graduate School of Engineering, Nagoya University, Japan, in 2018, authored by T. Oka et al. (Okada team), entitled "Evaluation of Magnetic Properties of Rotating YBCO Superconducting Disks Utilizing Flux Pinning Characteristics." The background of this research is that the dynamic behavior of the magnetic flux pinning effect of superconductors in a rotating state is not yet clear, which is crucial for the application of superconducting rotating machinery. Research methods: A 50 mm diameter YBCO superconducting disk (critical current density Jc = 20 kA / cm² @ 77 k) was fabricated. An axial magnetic field (0.1-1 T) was applied in a liquid nitrogen environment to drive the disk to rotate at 0-1000 RPM, and the radial magnetic flux density distribution was measured using a Hall probe array. Experimental results: At 0 RPM, the magnetic flux of the static magnetic field superconducting disk is non-uniformly distributed, with a maximum trapping magnetic field of 0.8 T at the center and 0.31 T at the edge. When the superconducting disk rotates at 300 RPM, the central magnetic field is 0.75 T and the edge magnetic field is 0.87 T, representing a 180% increase in magnetic flux offset compared to the initial edge magnetic field. When the superconducting disk rotates at 500 RPM, the central magnetic field is 0.68 T and the edge magnetic field reaches 1.24 T, representing a 300% increase in magnetic flux offset compared to the initial edge magnetic field. These results clearly demonstrate that the magnetic flux distribution shifts significantly towards the edge of the disk, causing the edge magnetic field to rise to 1.24 T, a 300% increase in shift and concentration compared to the initial edge magnetic field. When the rotation speed exceeds 800 RPM (critical state), the flux lines undergo large-scale depinning, resulting in a sharp 30% drop in the magnetic field. The study concludes that the centrifugal force generated during superconductor rotation alters the magnetic flux pinning balance, leading to a redistribution of magnetic flux. This phenomenon proves that rotational motion of the superconductor is an effective means of controlling superconducting magnetic flux, but it is necessary to avoid exceeding the critical rotation speed.

[0006] Based on the above experimental results, we can conclude that the initial magnetic field strength ranged from a maximum of 0.83T to a minimum of 0.31T, averaging around 0.565T. When the disk's rotational speed reached 500 RPM, the average magnetic field strength reached 0.68 + 1.24 = 1.92 / 2 = 0.96T. Where does the extra 0.40T of magnetic flux come from? My analysis suggests that this increased magnetic flux is an enhancement effect resulting from the combined effect of external energy and the rotation of the superconducting disk, which in turn amplifies the Earth's own magnetic field. Therefore, the Earth itself is a giant generator, with varying intensities of magnetic flux existing throughout its entire range. The rotation of the superconductor within the Earth's own magnetic field, due to the superconducting's perfect diamagnetic shielding and focusing effect, inevitably results in a focused driving magnetic field. If a superconducting coating is applied to the surface of superconducting materials or various suitable materials, this combination of a turbine rotor and outer shell structure with perfect diamagnetic properties can also achieve the goal of exciting and focusing the Earth's magnetic field to generate large-scale electricity.

[0007] Based on current theories and experiments, the experimental results of the rotating superconducting disk by Okada's team are, in fact, a basic demonstration of the principle of a flux pump using the Meissner perfect diamagnetism effect of a superconductor. If a superconducting flux pump with a pump-like structure is designed and manufactured, it would be possible to rotate and focus artificially generated magnetic flux, including magnetic flux from the Earth's own magnetic field, to achieve the goal of directional flux flow.

[0008] Several universities in China have conducted research on flux pumps and have applied for four patents. These are as follows:

[0009] 1. High-voltage output type flux pump (Sichuan University, CN117542602B):

[0010] Core design principle: The three-phase AC core and the DC bias core form a magnetically coupled air gap; the traveling wave magnetic field and the DC bias magnetic field are superimposed to induce a volt-level DC voltage on the superconducting stator (201).

[0011] Advantages: Output voltage reaches 5-10V, which can directly drive kA-level superconducting magnets without the need for current leads.

[0012] The aforementioned invention patent mainly utilizes a static structure to achieve the superposition of magnetic flux deflection and movement to output DC current. Its advantages are compact structure and no moving parts; its disadvantage is low output power. Experimental data can be found in Appendix II.

[0013] 2. Magnetic field coupled flux pump (Tianjin University, CN118737615A):

[0014] Core design principle: The secondary winding of the transformer and the superconducting flux bridge form a closed loop; the electromagnet applies an alternating magnetic field, inducing a DC voltage across the flux bridge.

[0015] Advantages: No moving mechanical parts, lifespan > 100,000 hours.

[0016] 3. Rotary permanent magnet type flux pump (Utility Model CN201620719807.5):

[0017] Core design principle: Three-stage permanent magnets (104 / 204 / 304) are arranged radially with decreasing diameters; when rotated, they generate a gradient magnetic field that cuts the superconducting plate (9 / 10), inducing an induced current.

[0018] Advantages: Simple structure and low cost.

[0019] This patent relates to achieving magnetic field gradient changes by rotating a magnet to guide the cutting of a stationary superconducting plate. The experiment verified that the proposed design using a rotating superconducting turbine to reduce the gradient is entirely feasible, enabling gradient changes in magnetic flux B and transmitting the magnetic field to achieve magnetic flux displacement focusing.

[0020] 4. Flux Pump Type Energy Output Unit (Patent number not disclosed, principle preferred):

[0021] Core design principle: Superconducting frozen large magnetic field coil and small magnetic field coil are superimposed; energy release is controlled by superconducting switch to achieve "1 joule input → tens of thousands of joules output".

[0022] This invention also belongs to static magnetic field conversion, and its design relevance to this invention is that it verifies the magnetic energy amplifier effect of magnetic field superposition, but it does not realize the magnetic flux guiding transmission by dynamic rotational focusing of superconductors.

[0023] Traditional turbine rotor structures are designed to pump and gather tangible substances such as air and water that can flow naturally. However, if the turbine rotor's pressurization function is combined with the perfect diamagnetic effect of superconducting materials, and a superconducting coating is applied to the turbine rotor and its outer shell, it is possible to shield and focus intangible magnetic flux, including the Earth's own magnetic flux, thereby enabling the directional movement of magnetic flux and achieving the effect of focusing and enhancing magnetic flux.

[0024] Based on the above comparative analysis, it is shown that the rotation of a superconducting disk can indeed cause the magnetic field strength to concentrate at the outer edge, achieving an increase of over 300%. This magnetic field concentration effect is an important result of the dynamic rotational change of the Meissner perfect diamagnetism effect in superconductors. Although the magnetic flux concentration change caused by this superconductor motion is a well-known phenomenon, it has significant experimental proof value for our research on structural innovation in superconductors and its practical engineering development applications. The four flux pump patents mentioned above have studied the principle and structure of flux pumps from different perspectives, but none of them have applied the Meissner perfect diamagnetism effect of superconducting materials to turbine rotational dynamics, achieving a similar goal as a flux pump that focuses magnetic flux to guide its movement, similar to a rotating superconducting turbine.

[0025] Therefore, to date, no technological solution has been found to combine turbine dynamics with the perfect diamagnetism of superconducting materials to achieve new innovations. This invention utilizes the perfect diamagnetism of superconducting materials with the turbine structure to achieve functional integration, enabling the superconducting turbine to achieve rotating active magnetic flux focusing. This is a revolutionary original, and readily available experimental data proves its commercial viability. This invention achieves ultra-high efficiency power generation through superconducting shell shielding focusing and a rotating superconducting airfoil impeller actively guiding the focused magnetic flux through a toroidal coil to capture the magnetic flux.

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. In particular, there are many different combinations and configurations between the body protected by the core structure of the present invention and different superconducting materials. Therefore, this specification cannot list all different embodiments, as well as other newly discovered superconducting materials. Any similar function achieved by combining novel superconducting materials with the proprietary structure of the present invention also falls within the scope of protection of the present invention.

[0066] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0067] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0068] In the description of the embodiments of the present invention, "multiple" means at least two.

[0069] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0070] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0071] Example 1

[0072] This embodiment discloses a superconducting turbine rotation-excited focusing flux power generation system and method.

[0073] like Figure 1 As shown, this embodiment includes

[0074] Vacuum cryogenic maintenance stainless steel tank unit 100, maintains a vacuum and cryogenic environment;

[0075] The drive control unit 300 includes a prime mover 301, which provides the system with drive rotational kinetic energy.

[0076] The closed coil captures magnetic flux to generate electricity and the load and control unit 400 controls the closed coil to receive changing magnetic flux, capture the generated electromotive force, and generate current.

[0077] The strong magnetic field generating coil and power control unit 500 generate a strong magnetic field under the supply and control of an external power source.

[0078] The rotating excitation and focusing magnetic flux functional unit 200 includes a turbine rotor 202 and a housing 204. The turbine rotor 202 has a radially extending airfoil structure for rotating excitation and focusing magnetic flux, and the housing 204 has a shell-shaped structure for shielding and focusing. The housing 204 is disposed around the turbine rotor 202.

[0079] Among them, the rotating excitation focusing magnetic flux functional unit 200 includes superconducting material, which is disposed in the main body structure region of the turbine rotor 202 and the outer shell 204;

[0080] The prime mover 301 drives the turbine rotor 202, which has an excitation and focusing function. The turbine rotor 202 rotates inside the shell 204, which has a shielding and focusing function. It excites and focuses the magnetic flux generated by the strong magnetic generation coil 501 and the magnetic flux of the Earth's magnetic field, and guides the closed coil to capture the magnetic flux to directly generate electricity.

[0081] Rotary Excitation Focusing Flux Functional Unit 200

[0082] The superconducting material comprises a ReBCO superconducting phase or a MgB2, Nb3Sn, or IBS superconducting alloy, and at least a portion of the structural surfaces of the turbine rotor 202 and the outer shell 204 are covered with the superconducting material.

[0083] The present invention utilizes the superconducting zero-resistance effect to move the external prime mover 301 into the vacuum working chamber 103. The superconducting motor coil and the strong magnetic generation coil 501 are designed as a self-sustaining internal circulation excitation mode that can be externally powered. In this mode, the external power supply to the superconducting motor and the strong magnetic generation coil 501 can be greatly reduced, thereby improving efficiency.

[0084] The system of this invention utilizes the Meissner perfect diamagnetism effect of superconductors. This effect can be understood as the superconductor being able to shield and guide focused magnetic flux. The magnetic flux can be excited and focused by rotating the superconducting shell and superconducting turbine blades, so that the magnetic flux generated by the strong magnetic field and the magnetic flux B of the Earth's magnetic field change with time. The superconducting shielding and guiding excitation and focusing effect is used to guide the strong magnetic flux and the magnetic flux of the Earth's magnetic field to a toroidal coil to capture the magnetic flux, directly and continuously generating an electromotive force to produce current.

[0085] Compared to the traditional induction generator, which strengthens the excitation magnetic field and rotates to change the magnetic flux B over time, thus transmitting the magnetic flux to the induction coil to generate electricity, this is an indirect induction power generation mode that transmits magnetic flux.

[0086] Therefore, the superconducting turbine rotation-excited focused flux power generation mode of the present invention is a power generation mode that directly excites and focuses flux through the rotation of a superconducting turbine shielding and guidance. It can be compared with the direct excitation and focusing flux power generation of a superconducting turbine flux pump. It is conceivable that the efficiency comparison between the indirect induction and direct excitation focusing power generation modes is very different.

[0087] This technical solution provides a novel superconducting turbine-driven flux-focusing generator principle. Driven by a prime mover 301, the superconducting turbine rotates and focuses a shielded excitation and focusing unit to generate a strong magnetic flux. Even without external strong magnetic flux, it can excite and focus the Earth's own magnetic field flux. The superconducting outer shell 204 shields and focuses the flux, guiding it into a toroidal trapping coil to directly and continuously generate an electromotive force. Furthermore, this power generation principle avoids the reaction force caused by Lenz's law (rejection and retention effect), reducing the power supply required by the prime mover 301. This principle enables the manufacture of a generator that directly shields and guides the magnetic flux to a closed toroidal coil for flux capture and generation. By utilizing the four efficiency-enhancing methods described above, this invention can significantly improve the efficiency of the superconducting turbine-driven flux-focusing generator.
