Electromagnetic induction power generation device

Abstract

The present invention specifically relates to a novel electromagnetic induction power generation device, which comprises an excitation magnetic field, a power generation magnetic field and a cylindrical magnetic conductor, the excitation magnetic field comprising a first cylindrical coil bobbin, an excitation coil and an excitation power supply, and the power generation magnetic field comprising a second cylindrical coil bobbin, an induction coil and a resistive load. The magnetic field of the excitation coil is conducted to the induction coil by means of the cylindrical magnetic conductor, so as to generate an induced electromotive force; when the cylindrical magnetic conductor moves leftwards and enters the excitation coil body, the magnetic field gradually increases, and the magnetic field at the right end of the cylindrical magnetic conductor also gradually increases, but the volume of contact between the cylindrical magnetic conductor and the induction coil gradually decreases, so that the induced electromotive force is generated in the induction coil. Since the resistive load is connected to the induction coil, a current is formed, and an induced magnetic field is consequently generated; when the cylindrical magnetic conductor moves left and right between the two cylindrical coil bobbins for power generation, the power consumption due to the left and right movement of the cylindrical magnetic conductor is very small. Thus, manufacturing a generator on the basis of the principle can greatly improve the efficiency of the generator.

Description

An electromagnetic induction power generation device Technical Field

[0001] The present invention relates to the field of magnetic induction power generation technology. The magnetic field moves in the induction coil, causing the magnetic flux in the induction coil to change. The induction coil induces an electromotive force output, which drives various electrical equipment to operate. Specifically, it refers to an electromagnetic induction power generation device. Background Art

[0002] In 1883, British scientist Michael Faraday discovered electromagnetic induction and created a copper plate generator to generate electricity, ushering in the era of electrification. A wide variety of electrical devices emerged, greatly facilitating human life. With the development of society, the use of various electrical appliances has skyrocketed, and the power of individual generators has grown ever larger. The largest have reached 1 million kilowatts, weighing over 8,000 tons. Each rotation can generate over 150 kilowatt-hours of electricity, consuming 1.4 to 1.8 million tons of coal annually. However, coal-fired power generation currently accounts for over 70-80% of the world's total electricity generation. The vast quantities of coal required to power the generators not only pollute the air and increase carbon emissions, but also consume a significant amount of the Earth's limited resources. An energy crisis is looming.

[0003] In physics, the principle of electromagnetic induction power generation is that a permanent magnet approaches or leaves an induction coil to generate an electromotive force. According to Lenz's law, when a magnet approaches an induction coil, a current is generated in the closed-circuit coil. The magnetic field of the induced current and the excitation magnetic field produce a magnetic force barrier. When the magnet approaches the induction coil, the magnetic field of the induction coil blocks the magnet from approaching. This is because the magnetic poles of the permanent magnet and the magnetic poles facing the induction coil are the same, and like poles repel each other. To make the induction coil generate an electromotive force, force or energy must be used to push the magnet close to the induction coil to generate electricity. Similarly, when the magnet leaves the induction coil, the magnetic poles of the induction coil are reversed, and the induction magnetic field facing the magnet's magnetic poles is reversed. When the poles become opposite poles, the two opposite magnetic poles will attract each other, preventing the magnet from moving away. In order to generate electricity, the magnet must be moved away with force, which also consumes energy and produces Ampere force power consumption. The total energy consumed is the output power value of the generator plus the mechanical loss and other losses of the generator, so the efficiency of the generator is always less than 100%. In order to improve the efficiency, since the invention of the generator, engineers all over the world have been working tirelessly to improve the technology of the generator, so that the efficiency has been close to the extreme. The efficiency of large generators has reached more than 99%, the efficiency of medium-sized generators is poor, and the efficiency of small generators is even worse.

[0004] It has been nearly 200 years since Faraday discovered the phenomenon of electromagnetic induction. Although generators have been greatly improved, the basic principle has always followed Faraday's electromagnetic induction mechanism, consuming energy to generate electricity. In order to improve this dilemma, it is urgent to develop a new electromagnetic induction power generation device that can greatly improve the efficiency of the generator, reduce coal burning, reduce carbon emissions, and better improve the human living environment and improve the quality of human life.

Using this principle to make a generator can greatly improve the efficiency of the generator. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be described in further detail below with reference to the accompanying drawings.

[0034] As shown in FIG1 , the structure of an electromagnetic induction power generation device of the present invention is shown, including an excitation magnetic field and a power generation magnetic field. The excitation magnetic field includes a first cylindrical coil bobbin 01, an excitation coil 03, and an excitation power supply 06, and the excitation coil 03 and the excitation power supply 06 are electrically connected; the power generation magnetic field includes a second cylindrical coil bobbin 02, an induction coil 04, and a resistive load 07, and the induction coil 04 and the resistive load 07 are electrically connected; between the excitation magnetic field and the power generation magnetic field, there is provided a cylindrical magnetic conductor 05 that can freely move left and right inside the first cylindrical coil bobbin 01 and the second cylindrical coil bobbin 02, and the first cylindrical coil bobbin 01 and the second cylindrical coil bobbin 02 are both grounded.

[0035] The first cylindrical coil bobbin 01 and the second cylindrical coil bobbin 02 are made of a thin-walled metal cylinder that is non-magnetic or poorly conductive;

[0036] The excitation coil 03 is wound with enameled wire, and its length is half of the length of the induction coil 04, and its diameter is larger than the diameter of the cylindrical magnetic conductor 05;

[0037] The induction coil 04 is made of enameled wire and is wound on the second cylindrical coil frame 02. The length of the induction coil 04 is twice the length of the excitation coil 03.

[0038] The cylindrical magnetizer 05 is made of a magnetic material with good magnetic conductivity, for example, a silicon steel sheet with good magnetic conductivity. The winding method is shown in FIG5 . The diameter of the cylindrical magnetizer 05 is smaller than the inner diameter of the first cylindrical coil bobbin 01 and also smaller than the inner diameter of the second cylindrical coil bobbin 02 . The length of the cylindrical magnetizer 05 is the same as that of the induction coil 04 . The cylindrical magnetizer 05 is solid or hollow.

[0039] The cylindrical magnetic conductor 05 enters and fills the excitation coil 03, and the length left in the induction coil 04 is not less than half of the induction coil 04;

[0040] The cylindrical magnetic conductor 05 can completely leave the excitation coil 03 and completely enter the induction coil 04, and the electromotive force of the induction coil 04 is zero.

[0041] In the structure described in the present invention, the excitation coil 03 and the induction coil 04 are arranged on the same straight line and are fixed. There is a certain distance between the two excitation coils 03 and the induction coil 04. The length of the induction coil 04 is twice that of the excitation coil 03. The length of the cylindrical magnetizer 05 is equal to the length of the induction coil 03. The initial state is that the cylindrical magnetizer 05 is in the induction coil 04.

[0042] As shown in Figures 2 and 3, the excitation coil 03 can be changed to a permanent magnet excitation, and multiple tile-shaped excitation magnets 09 are spliced ​​into a cylindrical shape. The excitation magnet 09 has an N pole inside and an S pole outside. The first cylindrical coil skeleton 01 and the second cylindrical coil skeleton 02 can be made into one piece, and the material is made of engineering plastics or other non-magnetic and non-conductive materials, and the enameled wire can be of ordinary national standard.

[0043] The working principle of the present invention is as follows:

[0044] When the cylindrical magnet 05 moves to the left, the volume entering the excitation coil 03 increases, and the magnetic flux induced in the cylindrical magnet 05 becomes larger. The cylindrical magnet 05 in the induction coil 04 leaves the induction coil 04, and the induced magnetic field in the induction coil 04 becomes larger while the volume becomes smaller. The polarity facing the induction coil 04 and the excitation coil 03 is the same, that is, N 励1 With N 感1 The polarity is the same, the cylindrical magnetic conductor 05 is induced by the magnetic field of the induction coil 04 to form an N on the left end 感2 , the right end is S 感2 , and the magnetic pole of the excitation magnetic field 03 is left S 励2 , Right N 励2 .

[0045] When the cylindrical magnet 05 moves to the right and away from the excitation coil 03, the volume of the cylindrical magnet 05 in the excitation coil 03 decreases, the magnetic flux at the left end of the cylindrical magnet 05 decreases, and then the magnetic flux at the right end also decreases, but the volume of the cylindrical magnet 05 in the induction coil 04 increases, the electromotive force of the induction coil 04 decreases, and the polarity facing the induction coil 04 and the excitation coil 03 is different, that is, N 励1 With S 感1 The polarity is different. The left end of the cylindrical magnetic conductor 05 is S due to the magnetic field induction of the induction coil 04. 感2 , the right end is N 感2 , and the excitation magnetic field pole is still on the left S 励1 , N on the right 励1 .

[0046] The positive and negative directions of the excitation power supply 06 need to be changed. After the cylindrical magnetizer 05 moves left and right once, the positive and negative directions of the excitation power supply 06 change once.

[0047] When the cylindrical magnet 05 moves left and right, there are two magnetic fields inside the magnet. One is the excitation magnetic field N 励2 、S 励2 and the induced magnetic field N 感2 、S 感2 .

[0048] When the cylindrical magnetic conductor 05 enters the induction coil 04, the excitation magnetic field becomes smaller, not larger; when it leaves the induction coil 04, the excitation magnetic field becomes larger, not smaller.

[0049] When the cylindrical magnet 05 moves to the left and enters the excitation coil 03, the cylindrical magnet 05 senses that the excitation magnetic field gradually increases as it moves to the left. The left end of the excitation magnetic field of the cylindrical magnet 05 is S 励1 , the right end is N 励1 The right end of the cylindrical magnetic conductor 05 is still in the induction coil 04. The induction coil 04 induces an electromotive force and generates a current magnetic field in the closed circuit. As the cylindrical magnetic conductor 05 enters the excitation coil, the excitation magnetic field gradually increases, and the excitation magnetic field in the induction coil 04 also gradually increases. Therefore, the polarity of the induction coil 04 is N. 感1 , the right end is S 感1 The magnetic field polarity formed by the induced magnetic field in the cylindrical magnet 05 is N at the left end. 感2 Right end S 感2 ;

[0050] The magnetic polarity of the induction coil 04 and the excitation coil 03 facing each other is the same, both N 励1 、N 感1 , the same poles are abandoned, but the two coils are fixed and cannot be abandoned. The polarity of the induced magnetic field inside the moving cylindrical magnet 05 is N on the left. 感2 , the right end is S 感2 , the polarity of the excitation magnetic field, the left end S 励2 Right end N 励2 , cylindrical magnet 05 left end N 感2 Facing N 励1 , the same poles abandon each other, hindering the cylindrical magnetic conductor 05 from moving to the left, which requires power consumption;

[0051] The cylindrical magnet 05 also has a right-end excitation magnetic field, and the magnetic pole formed at the right end of the cylindrical magnet 05 is N 励2 , the magnetic pole generated at the left end of the induction coil 04 is N 感1 , N 励2 Facing N 感1 , and also generates a repulsive force, but the direction is to the left. The thrust of the left end of the cylindrical magnet 05 is to the right, and the thrust of the right end is to the left. One is to the left and the other is to the right. The two forces are added together, and the sum is zero, and the two forces cancel each other out. When the cylindrical magnet 05 moves left and right to generate electricity, there is only friction between the cylindrical magnet 05 and the coil frame. The generator made according to this principle will greatly improve its efficiency and can greatly reduce the energy consumption used for power generation.

[0052] The characteristic of the present invention is that a cylindrical magnetizer 05 is added in addition to the excitation coil 03 and the induction coil 04. The excitation coil 03 and the induction coil 04 are fixed, and the cylindrical magnetizer 05 moves left and right to generate electricity by changing the magnetic flux.

[0053] Specifically, as shown in FIG4 , when the cylindrical magnetizer 05 moves to the left and enters the excitation coil 03, the magnetic flux in the body gradually increases, causing the magnetic flux in the induction coil 04 to also increase. When the magnetic flux of the cylindrical magnetizer 05 in the induction coil 04 increases, it does not enter the induction coil 04 but leaves the induction coil 04. The magnetic poles of the induction coil 04 on the right side of the cylindrical magnetizer 05 are the same, and the like poles repel each other, helping the cylindrical magnetizer 05 to move to the left, generating a thrust that helps push the cylindrical magnetizer 05 to move to the left. However, the cylindrical magnetizer 05 is different at the left end of the permanent magnet. The magnetic poles of the induced current magnetic field and the excitation magnetic field face the same magnetic poles, and the like poles repel each other, hindering the cylindrical magnetizer 05 from moving to the left, generating a resistance.

[0054] Under the condition that the excitation coil 03, the induction coil 04, the cylindrical magnet 05 and the manual thrust are in the same straight line, when the manual force pushes the magnet to move, four forces are generated:

[0055] 1. Manually push the cylindrical magnet 05 with force F1 to the left.

[0056] 2. Excitation magnetic field N at the right end of cylindrical magnet 05 励2 and the induced current magnetic field N 感1 The repulsive force F2 is to the left.

[0057] 3. The right end of the excitation coil magnetic field N 励1 and the induced magnetic field N at the left end of the cylindrical magnet 05 感2 The repulsive force F3 generated between them is to the right.

[0058] 4. Friction resistance f4 of the reciprocating motion of the cylindrical magnet 05.

[0059] Assuming the force to the left is + and the force to the right is -, the formula for calculating the artificial thrust F1 is: F1 = [(+F2) + (-F3)] + (-f4)

[0060] In the formula: |F2|=|F3| [(+F2)+(-F3)]=[0] F1=[0]+(-f4) F1=-f4

[0061] The leftward force mentioned above is positive, so F1 to the left is +F1, F2 to the left is +F2, F3 to the right is -F3, and f4 is the friction force, which is -f4. The absolute value of |F3| is equal to the absolute value of |F2|, and the sum of positive and negative values ​​equals zero. The artificial thrust F1 is equal to the friction force -f4 generated by the cylindrical magnet 05 in the cylindrical coil bobbins 01 and 02. When F1 = -f4 and F1 > f4, the cylindrical magnet 05 can move left and right in the first cylindrical coil bobbin 01 and the second cylindrical coil bobbin 02 to generate electricity. As can be seen from the formula, the total power consumed in pushing the cylindrical magnet 05 is the friction force f4 of the left and right movement. According to the above-mentioned electromagnetic induction principle, the cylindrical magnet 05 only suffers frictional losses when moving left and right in the two coils.

[0062] The length dimensions of the cylindrical magnetizer 05, induction coil 04, and excitation coil 03 of the present invention are not absolute. The cylindrical magnetizer 05 cannot be in a saturated state under any circumstances. It can be close to saturation under the condition of maximum magnetic flux. When the cylindrical magnetizer 05 moves left and right in the excitation coil 03 and the induction coil 04 to generate electricity, there is only friction loss.

[0063] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
