Description

Technical Field

[0001] This invention relates to the field of environmental energy conversion, and in particular to a superconducting power generation device and power generation method. Background Technology

[0002] Exploring space is one of the directions of human technological development. With the advancement of technology, space exploration activities are becoming increasingly frequent. Known human footprints have already reached the Moon and Mars, and are expected to extend to even more distant celestial bodies. Due to the limited intensity of solar radiation on other celestial bodies, the environmental temperatures on celestial bodies in the outer solar system are far lower than the surface temperature of Earth. These environmental temperatures are close to the superconducting transition temperature of type II superconductors. Current superconducting power generation devices utilize superconducting materials primarily by leveraging their excellent critical current density, using them as cables in generator components, such as rotating superconducting generators, high-speed levitation superconducting generators, or superconducting wind power generation devices for wind energy harvesting. Research on broader environmental mechanical energy conversion is lacking.

[0003] To address the technical shortcomings in the application of superconducting materials in superconducting power generation devices on low-temperature celestial bodies in the outer solar system, it is necessary to make improvements. Summary of the Invention

[0013] Preferably, in the superconducting power generation device, the magnetic field strength on the surface of the permanent magnet is 30mT to 1.0T.

[0014] Preferably, the superconducting power generation device further includes a container, in which the superconductor and the conductive coil are located, and the permanent magnet is located outside the container. The container is also provided with a cooling channel, through which the cooling medium enters the container and cools the superconductor.

[0019] Provide the aforementioned superconducting power generation device;

[0020] A cooling medium is introduced to cool the superconductor, trapping magnetic flux and generating magnetic levitation force to levitate the permanent magnet.

[0021] Applying a force to a permanent magnet causes it to vibrate, changing the relative position between the permanent magnet and the conductive coil. This alters the magnetic flux passing through the conductive coil, inducing an electromotive force and converting environmental mechanical energy into electrical energy.

[0022] The superconducting power generation device of the present invention has the following advantages over the prior art:

[0023] The present invention discloses a superconducting power generation device and method. The power generation device includes a superconductor, a conductive coil, a permanent magnet, and a cooling medium. The superconductor is made of a type II superconducting material. When the ambient temperature is below its superconducting critical temperature, the type II superconducting material can generate a magnetic levitation force on the external magnet, causing the permanent magnet to levitate. When a force is applied to the permanent magnet, and the force is removed, the permanent magnet changes position relative to the conductive coil, causing a change in the magnetic field distribution around the conductive coil. Consequently, the magnetic flux through the coil changes, generating an induced electromotive force inside the coil, thus realizing the conversion of mechanical energy into electrical energy. The device of the present invention can realize the conversion of ambient mechanical energy into electrical energy in ultra-low temperature environments, and can solve the energy source problem of distant low-temperature celestial bodies.

[0034] This application provides a superconducting power generation device, such as... Figure 1 As shown, it includes:

[0035] Superconductor 1, which is made of a type II superconducting material;

[0036] Conductive coil 2 is located above superconductor 1;

[0037] permanent magnet 3;

[0038] Cooling medium is used to cool the superconductor to a temperature below the superconducting critical point temperature. After the superconductor is cooled, it captures magnetic flux and generates magnetic levitation force to levitate the permanent magnet.

[0039] It should be noted that the superconducting power generation device of this application embodiment includes a superconductor 1, a conductive coil 2, a permanent magnet 3, and a cooling medium. The superconductor 1 is made of a second type of superconducting material. The second type of superconducting material can capture magnetic flux and generate magnetic levitation force on the external magnet when the ambient temperature is lower than its superconducting critical temperature. This property can be used to create a certain relative distance between the magnetic / electric structure of the electromagnetic power generation device. Specifically, the superconductor 1 generates magnetic levitation force when its temperature is lower than the superconducting critical temperature, causing the permanent magnet 3 to levitate. In this application, the cooling medium is used to provide a low-temperature environment and to cool the cooling medium. Obviously, this device can be used directly in a low-temperature environment that can cool the superconductor to a temperature lower than the superconducting critical temperature without the need for additional cooling of the superconductor 1. When the permanent magnet 3 is suspended by the magnetic levitation force generated by the superconductor 1, a force can be applied to the permanent magnet 3, specifically a force opposite to the magnetic levitation force. When the force is removed, the permanent magnet 3 changes position relative to the conductive coil, causing a change in the magnetic field distribution around the conductive coil. Consequently, the magnetic flux through the coil changes, generating an induced electromotive force inside the coil, thus realizing the conversion of mechanical energy into electrical energy. The device of this invention can realize the conversion of environmental mechanical energy into electrical energy in ultra-low temperature environments, and can solve the energy source problem on distant low-temperature celestial bodies.

[0040] In some embodiments, the second type of superconducting material includes YBa2Cu3O7, (Bi,Pb)2Sr2Ca2Cu3O x HgBa2CaCu2O x HgBa2Ca2Cu3O x Tl2Ba2Ca2Cu3O x , HgTlBaCaCuO, MgB2, PbMo6S8, V3Si, V3Ga, Nb3Ge, Nb3Al, Nb3Sn, Nb 37 Ti 63 At least one of Nb. For example, the critical superconducting temperature of YBa2Cu3O7 is as high as 90K (-185.15℃), which breaks through the "temperature barrier" of liquid nitrogen (77K) and is also higher than the temperature of celestial bodies in the outer solar system (20-30K).

[0041] In some embodiments, the conductive coil 2 is a metal conductive coil, specifically including but not limited to gold, silver, copper, etc., preferably a copper conductive coil. Copper conductive coils have very low resistivity in ultra-low temperature environments, which enables the entire power generation device to have high power output characteristics.

[0042] In some embodiments, the permanent magnet 3 is made of any one of neodymium iron boron alloy, aluminum nickel cobalt alloy, ferrite permanent magnet material, rare earth cobalt permanent magnet material, and iron cobalt vanadium permanent magnet alloy. The shape of the permanent magnet 3 is not required and can be a cube, cuboid, cylinder, etc. The specific shape can be selected according to the application.

[0043] In some embodiments, the magnetic field strength on the surface of the permanent magnet 3 is 30mT to 1.0T.

[0044] In some embodiments, a container 4 is also included, in which the superconductor 1 and the conductive coil 2 are located, and the permanent magnet 3 is located outside the container 4. A cooling channel 41 is also provided on the container 4, through which the cooling medium enters the container 4 and cools the superconductor 1.

[0045] Specifically, in the above embodiment, the superconductor 1 and the conductive coil 2 are both fixed to the container 4, and a cooling channel 41 is also opened on the container 4. A cooling medium is introduced into the container 4 through the cooling channel 41 to cool the superconductor.

[0046] In some embodiments, the cooling medium includes any one of liquefied carbon tetrafluoride, liquid nitrogen, liquid hydrogen, and liquid helium.

[0047] In some embodiments, the conductive coil 2 is a multi-turn coil wound with copper wire, the diameter of which is 0.1 to 1 mm.

[0048] In some embodiments, the container 4 is also filled with thermal insulation material 43.

[0049] For details, please refer to the following again. Figure 1 As shown, a support 42 is provided inside the container 4. The conductive coil 2 and the superconductor 1 are both fixed on the support 42. A cooling channel 41 is provided inside the container 4. One end of the cooling channel 41 is close to the bottom of the superconductor 1, and the other end extends out of the container 4. At the same time, insulation material 43 is also provided inside the container 4. In practice, insulation material 43 can also be wrapped around the outer periphery of the outer wall of the container 4. Specifically, the insulation material 43 can be foam insulation material, etc.

[0050] In some embodiments, the end of the conductive coil 2 extends out of the container 4, and the extended portion serves as an electrode.

[0051] Based on the same inventive concept, this application also provides a method for generating electricity, including the following steps:

[0052] S1. Provide the above-mentioned superconducting power generation device;

[0053] S2. A cooling medium is introduced to cool the superconductor, capture the magnetic flux, and generate a magnetic levitation force to levitate the permanent magnet.

[0054] S3. Applying a force to the permanent magnet causes it to vibrate, changing its relative position to the conductive coil. This alters the magnetic flux passing through the coil, inducing an electromotive force and converting environmental mechanical energy into electrical energy.

[0055] The power generation method of this application provides the aforementioned power generation device, in which a permanent magnet is placed above a conductive coil, and then a cooling medium is introduced to cool the superconductor. When the temperature of the superconductor is below its superconducting critical temperature, magnetic flux can be captured, and a magnetic levitation force is generated on the permanent magnet, thereby suspending the permanent magnet. A force is applied to the permanent magnet, specifically, a force opposite to the direction of the magnetic levitation force is applied to the permanent magnet. Since the magnetic levitation force is upward, a downward force is applied to the permanent magnet. When the force is removed, the permanent magnet returns to its levitation equilibrium position under the action of the upward magnetic levitation force. Because the permanent magnet has changed position relative to the conductive coil, the magnetic field distribution around the conductive coil is changed, and thus the magnetic flux passing through the conductive coil changes, generating an induced electromotive force inside the conductive coil, thereby realizing the conversion of mechanical energy into electrical energy.

[0056] Specifically, applying a force opposite to the magnetic levitation force to the permanent magnet can come from the impact of a small object on the permanent magnet, the impact of airflow on the permanent magnet, or vibrating the entire device, thereby causing the permanent magnet to vibrate and changing its relative position to the conductive coil. For example, a weight can be released from a certain height above the permanent magnet, causing it to fall onto the permanent magnet. The resulting impact force causes the permanent magnet to descend. Subsequently, as the weight falls, the permanent magnet is subjected to an upward magnetic levitation force and returns to its levitation equilibrium position. Because the magnet's position relative to the coil has changed, an induced voltage is generated. The following further illustrates the power generation device and method of this application with specific embodiments.
