Abstract
Description
Technical Field
[0001] The present invention relates to the field of inductive electromagnetic rings, and particularly to a branched electromagnetic ring and a method for extracting weak electric energy. Background Art
[0002] The principle of electromagnetic induction states that a changing magnetic field generates an electromotive force, and an electric current generates a magnetic field. After providing a suitable electrical load to the conductor that generates the electromotive force, the movement of charges, that is, an electric current, is naturally generated by Ampere's law, and this electric current will generate a superimposed secondary magnetic field. Controlling the change of the magnetic field, changing the charge movement characteristics, and changing the characteristics of the electrical load will all lead to changes in the energy conversion at the load end and its conversion efficiency. Currently, the extraction and utilization of weak electric energy based on the principle of electromagnetic induction have become a new research direction. Summary of the Invention
[0003] In order to solve the above technical problems, the present invention provides a branched electromagnetic ring and a method for extracting weak electric energy.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a branched electromagnetic ring, the branched electromagnetic ring is a planar structure, and the planar structure is composed of an upper carrier layer, an upper core layer, a dielectric isolation layer, a lower core layer, and a lower carrier layer stacked in sequence from top to bottom;
[0005] The upper core layer and the lower core layer have the same structure and material properties. The upper core layer and the lower core layer are each composed of an electromagnetic ring in the middle and branches on both sides of the electromagnetic ring. A load interface is provided on the electromagnetic ring. The structures of the branches on both sides are centrosymmetric about the center point of the electromagnetic ring. The materials of the branches on both sides of the upper core layer and the lower core layer have asymmetry, and the material of the electromagnetic ring has asymmetry;
[0006] The dielectric isolation layer electrically isolates the upper core layer and the lower core layer, and the upper core layer and the lower core layer are centrosymmetric about the center point of the dielectric isolation layer.
[0007] Further, both the upper carrier layer and the lower carrier layer are a carrier layer for fixing, protecting, and providing electrical insulation to the outside.
[0008] Further, the dielectric isolation layer is made of insulating glue or plastic film.
[0009] Further, the electromagnetic ring is a single-turn conductor ring, the conductor ring is a centrosymmetric figure, and the conductor ring is circular or elliptical or square or rhombus or octagon.
[0010] Further, one side of the branch of the upper core layer or the lower core layer is made of a good conductor material; the other side of the branch is composed of an alternating connection of a good conductor material and a ferromagnetic conductor material; the branches on one side and the other side of the upper core layer have the same shape but different materials. The branch on one side of the upper core layer is made of a good conductor material, and the branch on the other side is made of a hybrid material formed by the alternating connection of a good conductor material and a ferromagnetic conductor material; the branches on one side and the other side of the lower core layer have the same shape but different materials. The branch on one side of the lower core layer is made of a good conductor material, and the branch on the other side is made of a hybrid material formed by the alternating connection of a good conductor material and a ferromagnetic conductor material.
[0011] Further, the electromagnetic rings of the upper core layer and the lower core layer are both formed by the alternating connection of two quarter-circular arcs of good conductor material and two quarter-circular arcs of ferromagnetic conductor material.
[0012] Further, the ferromagnetic conductor material of the electromagnetic ring of the upper core layer coincides with the good conductor material of the electromagnetic ring of the lower core layer, and the ferromagnetic conductor material of the electromagnetic ring of the lower core layer coincides with the good conductor material of the electromagnetic ring of the upper core layer.
[0013] Further, the branch made of the good conductor material on the upper core layer and the branch made of the hybrid material on the lower core layer are on the same side, and the branch made of the good conductor material on the lower core layer and the branch made of the hybrid material on the upper core layer are on the same side.
[0014] Further, there are two load interfaces on the upper core layer and two load interfaces on the lower core layer, and the load interfaces on the upper core layer and the load interfaces on the lower core layer are symmetrically arranged.
[0015] The method for extracting weak electric energy from the branch electromagnetic ring is as follows:
[0016] The electric field distributions on the upper core layer and the lower core layer form a complementary structure. When the upper core layer moves in the magnetic field, according to the principle of electromagnetic induction, an induced electromotive force will be generated on it; when the magnetic field in the surrounding environment changes, an induced electromotive force will also be generated on the lower core layer;
[0017] The induced electromotive force will drive the charges to move towards the ends of the branches on both sides, forming a transient current at various parts of the entire branch until the electric field formed by the charge distribution reaches equilibrium with the induced electromotive force;
[0018] Different materials have different effects on the movement of charges, which will result in different electric field intensities when the charges move, thus generating different voltage distributions along the axial direction. Among them, the induced magnetic field generated by the transient current on the ferromagnetic conductor material is enhanced under the action of ferromagnetic properties, and the change of this magnetic field induces a stronger reverse current, resulting in a much higher transient electromotive force at both ends of the material than that of the good conductor material under the same total transient current;
[0019] Under the action of the same magnetic field change, the directions and total magnitudes of the induced electromotive forces generated in the upper core layer and the lower core layer are the same. However, due to the opposite placement directions, the distribution laws of the induced electromotive forces in the overlapping part are opposite. Due to the asymmetry between the two branches of a single layer, there is a potential difference between the two layers in the overlapping part on the electromagnetic ring;
[0020] In the case of asymmetric material layout, the change of the transient induced electromotive force in the direction of the two branches on both sides of the electromagnetic ring is gentle in the section of the good conductor material, and the change slope of the electromotive force in the section of the ferromagnetic conductor material is steeper. According to Ohm's law, voltages are accumulated at both ends of each section of the ferromagnetic conductor material, and the transient distribution of its voltage changes with parameters such as the external magnetic field, movement, and time, and even the polarity will reverse. However, the stepped characteristics of the distribution are determined by the structure and material;
[0021] The dielectric isolation layer electrically isolates the upper core layer and the lower core layer. The dielectric isolation layer forms a large capacitance between the layers, increasing the charge storage capacity. Under the action of the induced electromotive force, the amount of charge required to reach the electromotive force balance increases, resulting in an increase in the transient current, and finally an increase in the transient current reflected at the load end. The effect of this increase in current is inversely proportional to the thickness of the dielectric isolation layer. Designing the dielectric isolation layer in a thin film shape can greatly improve the energy acquisition efficiency;
[0022] At the same time, according to Thevenin's theorem, for the structures of the ports on the two conductive layers of the upper core layer and the lower core layer, any network that can be equivalent to a matching impedance from the port can become its efficient load. A mismatched load can also use this structure to extract energy, but the efficiency will be reduced due to the mismatch.
[0023] The beneficial effects of the present invention are as follows: By controlling the characteristics of the distributed load on the ring and adding disturbance branches outside the ring, and at the same time controlling the characteristics of the distributed load of the branches themselves to enhance their imbalance, and obtaining efficient energy conversion from the load of the electromagnetic ring; The present invention proposes a technical solution for extracting weak electric energy based on the principle of electromagnetic induction. This method can extract weak energy by using the induced electromotive force generated by the movement of the electromagnetic ring in the magnetic field or the change of the magnetic field.

[0028] As Figure 1 and Figure 2 shown, a branch electromagnetic ring, the branch 6 electromagnetic ring 8 is a planar structure, and the planar structure is composed of an upper carrier layer 1, an upper core layer 2, a dielectric isolation layer 3, a lower core layer 4, and a lower carrier layer 5 stacked in sequence from top to bottom;
[0029] The upper core layer 2 and the lower core layer 4 have the same structure and material properties. Both the upper core layer 2 and the lower core layer 4 are composed of an electromagnetic ring 8 in the middle and branches 6 on both sides of the electromagnetic ring 8. A load interface 7 is provided on the electromagnetic ring 8. The structures of the branches 6 on both sides are centrosymmetric about the center point of the electromagnetic ring 8. The materials of the branches 6 on both sides of the upper core layer 2 and the lower core layer 4 are asymmetric, and the material of the electromagnetic ring 8 is asymmetric;
[0030] The dielectric isolation layer 3 electrically isolates the upper core layer 2 and the lower core layer 4, and the upper core layer 2 and the lower core layer 4 are centrosymmetric about the center point of the dielectric isolation layer 3.
[0031] Both the upper carrier layer 1 and the lower carrier layer 5 are carrier layers for fixing, protecting, and providing electrical insulation to the outside.
[0032] The dielectric isolation layer 3 is made of insulating glue or plastic film.
[0033] The electromagnetic ring 8 is a single-turn conductor ring, and the conductor ring is a centrosymmetric figure. The conductor ring is circular or elliptical or square or rhombus or octagon.
[0034] One side of the branch 6 of the upper core layer 2 or the lower core layer 4 is composed of a good conductor material; the other side of the branch 6 is composed of an alternating connection of a good conductor material and a ferromagnetic conductor material; the branches on one side and the other side of the upper core layer 2 have the same shape but different materials. One side branch of the upper core layer 2 is composed of a good conductor material, and the other side branch is composed of a mixed material formed by an alternating connection of a good conductor material and a ferromagnetic conductor material; the branches on one side and the other side of the lower core layer 4 have the same shape but different materials. One side branch of the lower core layer 4 is composed of a good conductor material, and the other side branch is composed of a mixed material formed by an alternating connection of a good conductor material and a ferromagnetic conductor material.
[0035] The electromagnetic rings of the upper core layer 2 and the lower core layer 4 are both formed by an alternating connection of two quarter-circular good conductor materials and two quarter-circular ferromagnetic conductor materials.
[0036] The ferromagnetic conductor material of the electromagnetic ring in the upper core layer 2 coincides with the good conductor material of the electromagnetic ring in the lower core layer 4, and the ferromagnetic conductor material of the electromagnetic ring in the lower core layer 4 coincides with the good conductor material of the electromagnetic ring in the upper core layer 2.
[0037] The branch formed by the good conductor material on the upper core layer 2 and the branch formed by the mixed material on the lower core layer 4 are on the same side, and the branch formed by the good conductor material on the lower core layer 4 and the branch formed by the mixed material on the upper core layer 2 are on the same side.
[0038] Both the upper core layer 2 and the lower core layer 4 have two load interfaces, and the load interfaces of the upper core layer 2 and the lower core layer 4 are symmetrically arranged.
[0039] A method for extracting weak electric energy from a branch electromagnetic ring is as follows:
[0040] The electric field distributions on the upper core layer 2 and the lower core layer 4 form a complementary structure. When the upper core layer 2 moves in a magnetic field, according to the principle of electromagnetic induction, an induced electromotive force will be generated on it; when the magnetic field in the surrounding environment changes, an electromotive force will also be generated on the lower core layer 4;
[0041] The induced electromotive force will drive the charges to move towards the ends of the two-side branches 6, forming transient currents at various parts of the entire branch until the electric field formed by the charge distribution reaches equilibrium with the induced electromotive force;
[0042] Different materials have different effects on the movement of charges, which will result in different electric field strengths when the charges move, thus generating different voltage distributions along the axial direction. Among them, the induced magnetic field generated by the transient current on the ferromagnetic conductor material is enhanced under the action of ferromagnetic properties, and the change of this magnetic field induces a stronger reverse current, resulting in a much higher transient electromotive force at both ends of the material than that of the good conductor material under the same total transient current;
[0043] In the case of asymmetric material layout, the transient induced electromotive force on the electromagnetic ring in the direction of the two-side branches 6 changes smoothly on the good conductor material section, and the change slope of the electromotive force on the ferromagnetic conductor material section is steeper. According to Ohm's law, voltages are accumulated at both ends of each section of the ferromagnetic conductor material, and its transient voltage distribution changes with parameters such as the external magnetic field, movement, and time, and even the polarity may reverse, but the stepped characteristics of the distribution are determined by the structure and materials;
[0044] The dielectric isolation layer 3 electrically isolates the upper core layer 2 and the lower core layer 4. The dielectric isolation layer 3 forms a large capacitance between the layers, increasing the charge storage capacity. Under the action of the induced electromotive force, the amount of charge required to move to reach the electromotive force balance increases, resulting in an increase in the transient current. Eventually, the transient current reflected at the load end increases. This increase in current is inversely proportional to the thickness of the dielectric isolation layer 3. Designing the dielectric isolation layer 3 in a thin film shape can greatly improve the energy harvesting efficiency;
[0045] At the same time, according to Thevenin's theorem, for the structures of the ports on the two conductive layers of the upper core layer 2 and the lower core layer 4, any network that can be equivalent to a matching impedance from the port can become its efficient load. A mismatched load can also use this structure to extract energy, but the efficiency will be reduced due to the mismatch.
[0046] The advantages of the present invention are as follows: By controlling the characteristics of the distributed loads on the control loop and adding perturbation branches outside the loop, and at the same time controlling the characteristics of the distributed loads of the branches themselves to enhance their imbalance, efficient energy conversion is obtained from the loads of the electromagnetic loop; The present invention proposes a technical solution for extracting weak electric energy based on the principle of electromagnetic induction. This method can extract weak energy by using the induced electromotive force generated by the movement of the electromagnetic loop in the magnetic field or the change of the magnetic field.
[0047] The above embodiments are not limitations on the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the technical solution of the present invention also fall within the protection scope of the present invention.

Among them, the induced magnetic field caused by the generation of transient current on the ferromagnetic conductor material is enhanced under the action of ferromagnetic characteristics.

However, the step characteristics of the distribution are determined by the structure and material. The dielectric isolation layer (3) electrically isolates the upper core layer (2) and the lower core layer (4). The dielectric isolation layer (3) forms a relatively large capacitance between the layers, thereby increasing the charge storage capacity.

The effect of this current increase is inversely proportional to the thickness of the dielectric isolation layer (3). The dielectric isolation layer (3) is designed in a thin film shape, which can greatly improve the energy acquisition efficiency. At the same time, according to the Thevenin theorem, the structure of the ports on the two conductive layers of the upper core layer (2) and the lower core layer (4) is such that any network that can be equivalent to a matching impedance at the port can become its efficient load.
