Description

Technical Field

[0001] The present application relates to the technical field of power generation devices, and in particular to a magnetically driven power generation device. Background Art

[0002] Power banks are commonly used as mobile power sources for charging mobile phones and other devices. They are easy to carry and can meet most people's needs. However, due to their limited storage capacity, they are not suitable for long-distance outdoor travel. Once the power bank runs out of power, it will become unusable.

[0003] Chinese invention patent CN108173412A discloses a magnetic power generation mobile device, the specific scheme of which is as follows: the device includes a pressure plate, on which a spring fixing needle, a spring, a semicircular fixing frame, a silicon steel sheet and a magnet are provided. The spring fixing needle is fixedly connected to the bottom of the pressure plate, the spring is fixedly connected to the spring fixing needle, the semicircular fixing frame is fixedly connected to the lower end of the spring fixing needle, the silicon steel sheet is fixedly connected to the lower end of the semicircular fixing frame, the magnet is fixedly connected to the inner side of the silicon steel sheet, a cam and a circular silicon steel sheet are provided on the right side of the magnet, the cam is fixedly connected to the right side of the magnet, and the circular silicon steel sheet is fixed. Connected to the right side of the cam, a rotating shaft, a baffle and a triangular shaft are provided on the left side of the magnet, the rotating shaft is fixedly connected to the inner side of the magnet, the baffle is fixedly connected to the top of the rotating shaft, the triangular shaft is fixedly connected to the left end of the rotating shaft, a bearing, a transmission and a generator motor are provided on the left side of the triangular shaft, the bearing is fixedly connected to the left end of the triangular shaft, the transmission is fixedly connected to the left end of the bearing, the generator motor is fixedly connected to the left end of the transmission, a circular shell and an upper cover are provided below the circular silicon steel sheet, the upper cover is fixedly connected to the upper end of the circular shell, and the circular shell is fixedly connected to the bottom of the circular silicon steel sheet.

[0004] The above patent document claims that it uses the principle of repulsion between like poles of magnets to rotate the generator motor to generate electricity, and the power provided is not limited by batteries. After carefully reading the patent document, the inventor found that its working principle is as follows: magnets use the principle of repulsion between like poles to generate a repulsive force, which can push the magnet to move. The movement of the magnet is transmitted to the triangular shaft through the rotating shaft, and the triangular shaft is then transmitted to the transmission through the bearing. The adjusted speed is transmitted to the generator motor through the transmission, and the generator motor converts mechanical energy into electrical energy. Although the device uses the repulsive force of the magnet, this force is not a continuous energy source. In order for the device to continuously generate electricity, a mechanism is needed to continuously readjust the position of the magnet to maintain the repulsive force between the magnets. This may require the interaction between the cam and the circular silicon steel sheet in the solution, as well as the elastic force of the spring to assist in resetting the magnet.

[0005] While the aforementioned patent document provides a technical concept for utilizing the principle of repulsion between like-pole magnets to rotate a generator motor and generate electricity, its practical application may suffer from the following drawbacks: the device includes multiple components and connections, such as the structural connections between a cam, circular silicon steel sheets, a rotating shaft, a triangular shaft, and bearings, and requires high assembly precision, which increases the complexity and difficulty of manufacturing and maintenance. Furthermore, the complex structure may lead to higher costs and a higher failure rate. Therefore, the magnetic power generation device disclosed in the aforementioned patent document is complex in structure and has high manufacturing and maintenance costs. Therefore, it is necessary to propose a new technical solution to address the problems existing in the prior art. Utility Model Content

[0027] The present application will be further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0028] In the description of this application: unless otherwise specified, "plurality" and "several" mean two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0030] It should be noted that the "coil" mentioned in this application refers to the stator part of the electromagnetic device. More specifically, it includes the following two main parts: an iron core and a winding, wherein: the iron core is a part made of iron or other magnetic materials, consisting of multiple stacked thin sheets to reduce eddy current loss and improve the conduction of magnetic flux. Its main function is to enhance the strength and guidance of the magnetic field; the winding is a copper coil made of conductive material (usually copper wire) wound on the iron core.

[0031] Example 1

[0032] This embodiment provides a magnetic driven power generation device, such as Figure 1 It mainly includes a first turntable 2 installed on the motor shaft 1 of the generator, a second turntable 3 coaxially arranged with the first turntable 2, and a spring mounting frame 4 installed on the outer edge of the second turntable 3. A spring mounting column 5 is eccentrically arranged on the disk surface of the first turntable 2. The spring mounting column 5 and the spring mounting frame 4 are used to install and fix several springs; a mounting shaft 6 is eccentrically arranged on the second turntable 3, and a plurality of connecting rods 7 are rotatably installed on the mounting shaft 6. Each connecting rod 7 is transmission-connected to a set of magnetic power generation modules.

[0033] Each set of magnetic power generation module includes a guide connecting rod assembly and a relative magnetic power generation assembly. The guide connecting rod assembly includes a guide main rod 8 hinged to the connecting rod 7 at one end. The relative magnetic power generation assembly includes a first coil 9, a magnet mounting frame 10 arranged in the first coil 9, a plurality of fixed magnets A arranged in the magnet mounting frame 10 at intervals along the length direction of the first coil 9, and a plurality of movable magnets B arranged at intervals on the guide main rod 8. Any two adjacent fixed magnets A generate a repulsive force on a movable magnet B arranged between them, so that the guide main rod 8 moves back and forth with the movable magnet B. The first coil 9 is electrically connected to the external circuit.

[0034] In this embodiment, the magnetic power generation module uses the principle of repulsion between like poles of magnets to make the guide main rod 8 move back and forth in the first coil 9. The structural principle of its power generation is mainly realized around the change of magnetic field and electromagnetic induction.

[0035] The structural principle of the magnetic drive power generation device provided in this embodiment is analyzed and explained below:

[0036] In this embodiment, the first turntable 2 is mounted on the motor shaft 1 of the generator as a rotating transmission component of the device; the second turntable 3 is coaxially arranged with the first turntable 2 to increase structural stability and provide an additional structural action connection point; the spring mounting frame 4 is mounted on the outer edge of the second turntable 3 to fix the spring; the spring mounting column 5 is eccentrically arranged on the disk surface of the first turntable 2, and is used together with the spring mounting frame 4 to fix the spring, which is used to provide restoring force to maintain the continuous rotation of the turntable; the second turntable 3 is eccentrically provided with a mounting shaft 6, and the connecting rod 7 is rotatably mounted on the mounting shaft 6 to transmit power between the rotational motion of the turntable and the reciprocating linear motion of the magnetic power generation module; one end of the guide main rod 8 of the magnetic power generation module is hinged to the connecting rod 7, which is inserted into the guide The fixed magnet A on the guide main rod 8 and the movable magnet B fixed on the guide main rod 8 use the principle of like poles repelling each other to push the movable magnet B to move. Therefore, the guide main rod 8 moves back and forth with the movable magnet B and drives the turntable to rotate through the connecting rod 7. Multiple springs complete the storage and release process through self-extension and contraction to maintain the continuous rotation of the turntable, and the rotation of the turntable can drive the motor shaft 1 of the generator to rotate, that is, the rotational movement of the rotor relative to the stator in the generator is realized, and the generator generates electricity; at the same time, when the movable magnet B in the first coil 9 moves under the repulsive force of the fixed magnet A, a changing magnetic field will be generated in the first coil 9, thereby inducing current in the circuit, and the current can be output and utilized through the external circuit connected to the first coil 9.

[0037] Of course, since the magnetic force will weaken, the power source formed by the repulsive force of the magnet is not long-lasting. Therefore, it will gradually slow down until it stops after working for a period of time. In the specific use process, the above-mentioned device can be maintained in continuous operation by means of external power. This external power can be manually supplemented by the user. For example, when it is found that its rotation speed has decreased, the guide main rod 8 or the connecting rod 7 is manually moved to destroy the trend of the movable magnet B in the first coil 9 gradually tending to a balanced state, thereby ensuring the continuous movement of the movable magnet B.

[0038] The above-mentioned method of adding energy through manual intervention is very suitable for users who travel long distances in the wild. The use of this device can meet their demand for electricity and get rid of the problem of limited energy storage of power banks. It can be used at any time and can also be used to charge power banks, mobile phones, cameras, etc.

[0039] The magnetic-driven power generation device disclosed in the above embodiment can ensure the transmission function of the structure while making the device compact and occupying a small space through the coaxially arranged first and second turntables, and the eccentric installation design of the springs, connecting shafts, etc. on the turntables. The structure of the magnetic power generation module is simple, the requirements for structural processing accuracy are relatively low, and the manufacturing, installation, maintenance and use costs are all low. In addition, since magnetic repulsion can provide stronger power, and the use of springs can reduce energy loss, the efficiency of energy conversion may be improved. Furthermore, this device does not rely on fossil fuels or limited resources, and is a clean energy conversion method. The number of connecting rods and magnetic power generation modules on the turntable can be increased as needed to improve the power generation capacity.

[0040] Example 2

[0041] This embodiment provides a magnetically driven power generation device. This embodiment is a structural improvement based on the structure of the magnetically driven power generation device provided in the first embodiment. Specifically:

[0042] See also Figure 2 The guide link assembly also includes a connecting disk 11 arranged on the guide main rod 8, the disk surface of the connecting disk 11 is perpendicular to the length direction of the guide link 12, and multiple fixed magnets A and multiple movable magnets B are located between the connecting rod 7 and the connecting disk 11; multiple connecting rods 12 are arranged on the disk surface of the connecting disk 11 close to the fixed magnet A, and the multiple connecting rods 12 form at least one circle around the periphery of the first coil 9 with the first coil 9 as the center; a second coil 14 is coaxially arranged around the periphery of the first coil 9, and the multiple connecting rods 12 forming a circle are located between the first coil 9 and the second coil 14.

[0043] In this embodiment, a sliding guide frame 13 is further provided on the disk surface of the connecting disk 11 close to the fixed magnet A. The sliding guide frame 13 is slidably connected to the outer surface or inner surface of the coil. When the connecting disk 11 moves back and forth along with the guide main rod 8, it drives the sliding guide frame 13 on it to move back and forth relative to the coil. The sliding guide frame 13 can guide the reciprocating movement of the connecting disk 11, so that the connecting disk 11 moves smoothly and stably, reduces friction and resistance, reduces energy loss, and improves mechanical efficiency.

[0044] In this embodiment, the end of the coil facing away from the connecting disk 11 and the magnet mounting frame 10 are both mounted on the fixing frame 15. The bottom of the fixing frame 15 is connected to the base. The generator is fixed on the base. The connecting rod 7 passes through the fixing frame 15 and is connected to the guide main rod 8. The fixing frame 15 is connected to the chassis so that the structure installed on the fixing frame 15 is stably installed to prevent displacement due to vibration or impact during operation, thereby ensuring the normal operation and long-term reliability of the power generation device.

[0045] Through the above-mentioned structural arrangement, when the guide main rod 8 reciprocates using the principle of like-pole repulsion of magnets, the coil and the fixed magnet A mounted on the magnet mounting frame 10 are both kept fixed by the fixing frame 15. The guide main rod 8 is fixed to each connecting rod 12 through the connecting disk 11 and drives each connecting rod 12 to move back and forth in the second coil 14, generating a changing magnetic field in the second coil 14, thereby inducing current in the circuit, and the current can be output and utilized through an external circuit connected to the second coil 14.

[0046] Of course, according to the arrangement of the above-mentioned connecting disk 11, connecting rod 12 and second coil 14, multiple connecting rods 12 can be arranged in two circles (or even three circles, four circles, etc.) around the first coil 9 with the first coil 9 as the center. The second coil 14 and the third coil are coaxially arranged on the periphery of the first coil 9 in sequence, and a circle of connecting rod 12 is respectively arranged between the first coil 9 and the second coil 14 and between the second coil 14 and the third coil; the second coil 14 and the third coil are both electrically connected to the external circuit.

[0047] In this embodiment, by providing the first coil 9 and the second coil 14 and surrounding the connecting rod 12 in a circle and being located between the two coils, the area where the magnetic flux changes can be increased, thereby possibly improving the intensity of the induced current.

[0048] In this embodiment, multiple fixed magnets A are installed on the guide main rod 8 at equal intervals. The magnetic force of any two adjacent fixed magnets A is the same. A movable magnet B is arranged between any two adjacent fixed magnets A, and the initial position of the movable magnet B is close to one of the fixed magnets A.

[0049] In this embodiment, by arranging multiple fixed magnets A and movable magnets B between the connecting disk 11 and the connecting rod 7, the coupling strength of the magnetic field can be increased, thereby improving the power generation efficiency. The relative movement between the fixed magnets A and the movable magnets B can generate stronger electromagnetic induction, thereby improving the power generation output.

[0050] This embodiment can also maintain the continuous operation of the above-mentioned device by manually intervening to toggle the connecting rod 7, the guide main rod 8, or the connecting plate 11. Compared with the first embodiment, this embodiment adds a portion of the induced current generating device through the connecting plate 11, the connecting rod 7, and the second coil 14, thereby improving the power generation capacity. In addition, the modular structural design of the connecting plate 11, the connecting rod 12, and the sliding guide frame 13 makes the overall structure of the device simple, the connection and fixation of each component are more reasonable, and the installation and maintenance are more convenient. The user can replace or adjust any part as needed.

[0051] Example 3

[0052] This embodiment provides a magnetically driven power generation device. This embodiment is a structural improvement based on the structure of the magnetically driven power generation device provided in the second embodiment. Specifically:

[0053] See also Figure 3 A plurality of movable magnets B can be installed on each connecting rod 12 installed on the connecting disk 11. A magnet mounting frame is provided in the coil outside the connecting rod 12, and a plurality of fixed magnets A are provided in each magnet mounting frame. In the coil, the movable magnets B and the fixed magnets A are arranged at intervals on each connecting rod 12. Any two adjacent fixed magnets A generate a repulsive force on a movable magnet B arranged between them, so that the connecting rod 12 moves back and forth with the movable magnet B.

[0054] In this embodiment, a fixed magnet A and a movable magnet B are also provided on the connecting rod 12, which is similar to the guide main rod 8 in the first coil 9. The connecting rod 12 in this embodiment can also reciprocate in the coil by utilizing the principle of like-pole repulsion of magnets, that is, the guide main rod 8 and each connecting rod 12 can reciprocate by utilizing the principle of like-pole repulsion of magnets, and are structurally connected through the connecting disk 11 to realize overall power transmission.

[0055] In this embodiment, by configuring multiple fixed magnets A and movable magnets B on the connecting rod 12, the magnetic force acting on the connecting rod 12 is more continuous and stable during the reciprocating motion. Each movable magnet B generates a repulsive force between the adjacent fixed magnet A, forming a continuous driving force, which can improve the power generation efficiency. In addition, since the magnetic field changes generated by the multiple movable magnets B during the reciprocating motion are increased, the rate of change of the magnetic field passing through the coil is increased, resulting in an increase in the output current. This enhanced electromagnetic induction effect significantly increases the overall power generation. Furthermore, by installing multiple movable magnets B on each connecting rod 12, the frequency and intensity of the magnetic force can be increased, thereby potentially improving the power generation efficiency of the device.

[0056] In this embodiment, by installing multiple movable magnets B on each connecting rod 12, the driving force during movement is distributed more evenly, which can effectively reduce the impact of vibration and impact on the system, thereby improving the stability of movement and reducing mechanical wear; and can make the overall structure of the device more compact.

[0057] Example 4

[0058] This embodiment provides a magnetically driven power generation device. This embodiment is a structural improvement based on the structure of the magnetically driven power generation device provided in the third embodiment. Specifically:

[0059] See also Figure 4The other end of the guide main rod 8 passes through the connecting disk 11 and extends into a fixed coil 16. One or more movable magnets B are fixed at intervals on the rod section of the guide main rod 8 extending into the fixed coil 16. The fixed coil 16 is fixedly installed on the base. A magnet mounting frame is provided in the fixed coil 16. A plurality of fixed magnets A are provided in the magnet mounting frame. The fixed magnet A is passed through and installed on the guide main rod 8, and the movable magnet B and the fixed magnet A are arranged at intervals on the guide main rod 8. Any two adjacent fixed magnets A generate a repulsive force on a movable magnet B arranged between them, so that the guide main rod 8 moves back and forth with the movable magnet B, and the fixed coil 16 is electrically connected to the external circuit.

[0060] In this embodiment, the fixed coil 16 and the guide main rod 8 are relatively separated in structural installation, and the user can conveniently perform modular maintenance and replacement, thereby improving the maintainability of the system and reducing maintenance costs and time; in addition, through the structural coordination of the fixed coil 16 and the guide main rod 8, the guide main rod 8 can generate an induced current in the fixed coil 16 during reciprocating motion, further improving the power generation and power generation efficiency.

[0061] Example 5

[0062] This embodiment provides a magnetically driven power generation device. This embodiment is a structural improvement based on the structure of the magnetically driven power generation device provided in the fourth embodiment. Specifically, the end of the guide main rod 8 away from the connecting rod 7 is connected to the bidirectional compensation module 17. Figure 5 When the magnetic-driven power generation device provided in the fourth embodiment is gradually decelerating, the bidirectional compensation module 17 can be used to supplement the power of the magnetic-driven power generation device to increase the movement speed of the magnetic-driven power generation device. When the movement speed of the magnetic-driven power generation device is increased to the target speed, the guide main rod 8 can be used to drive the bidirectional compensation module 17 to generate inductive power to increase the power generation.

[0063] In this embodiment, the bidirectional compensation module 17 mainly includes a crankshaft, on which a plurality of transmission rods are rotatably connected. Each transmission rod is provided with a coil. The end of the transmission rod is slidably connected to the inside of the corresponding coil. Each coil is connected to the electrical output end of the generator through a wire, and a switch is provided on the wire to control the on-off circuit between the coil and the electrical output end of the generator.

[0064] When the switch is closed, the coil is energized, and the transmission rod reciprocates along the coil under the action of electromagnetic force, driving the crankshaft to rotate. The crankshaft is connected to the guide main rod 8, which is driven by the crankshaft to reciprocate within the first coil 9. In other words, when the magnetically driven generator provided by Example 4 is gradually decelerating, closing the switch allows the bidirectional compensation module 17 to supplement the power to the magnetically driven generator, thereby increasing its speed.

[0065] When the switch is turned off, the crankshaft rotates, driven by the guide main rod 8, driving the transmission rod on it to reciprocate within the coil, electrically connecting the coil to the external circuit. In other words, when the magnetically driven generator reaches the target speed, the guide main rod 8 drives the bidirectional compensation module 17 to generate inductive power, thereby increasing power generation.

[0066] In this embodiment, a speed detection device may be added to detect the movement speed of the guide main rod 8 in real time. A target maximum speed and a target minimum speed may be preset by the speed detection device. When the guide main rod 8 is detected to have reached the target minimum speed, the speed detection device sends a signal. At this time, a switch may be closed, and part of the current generated by the generator of the device may be used to power the bidirectional compensation module 17, thereby starting the bidirectional compensation module 17 to supplement power to the guide main rod 8. When the guide main rod 8 is detected to have reached the target maximum speed, the speed detection device sends a signal. At this time, the switch may be opened, cutting off the power supply from the generator of the device to the bidirectional compensation module 17, and driving the bidirectional compensation module 17 to generate an induced current through the guide main rod 8.

[0067] Of course, the above-mentioned speed detection device is not necessary. During specific use, the user can test and record the power attenuation cycle of the magnetic-driven power generation device provided in Example 4. For example, from the start of the device, it is measured that the device reaches the maximum speed in time a, the device movement speed decays to one-third of the maximum speed in time b, and the device movement stops completely in time c. After obtaining the data, the user can perform timing during use and manually close or cut off the switch according to the timing cycle to maintain continuous movement of the device.

[0068] Of course, the above-mentioned two-way compensation module 17 cannot maintain the movement of the device for a long time. It can only extend the working time of the device to a certain extent and play a certain compensation role. Therefore, during use, the user can provide external energy supply through manual intervention to ensure that the device will not stop during use to ensure its own electricity needs. The manual intervention method can be manually moving the guide main rod 8, connecting rod 7 or connecting disk 11, etc., to break the trend of the device gradually tending to a balanced state, so as to achieve the purpose of continuously utilizing the principle of like poles repelling each other of magnets to ensure the continuous supply of power source for the device.

[0069] In summary, the present application provides a magnetically driven power generation device, which utilizes the principle of repulsion between like poles of magnets to cause a guide main rod to move back and forth in a first coil, thereby generating an induced current in the first coil. At the same time, the movement of the guide main rod can also drive the motor shaft of the generator to rotate to realize power generation by the generator. Therefore, the present application realizes multi-mode power generation through a set of devices, thereby improving the power generation amount and power generation efficiency. In addition, the magnetically driven power generation device disclosed in the present application can ensure the transmission function of the structure while making the device compact and occupying a small space by coaxially arranging the first and second turntables, and the eccentric installation design of the springs, connecting shafts, etc. on the turntables. The structure of the magnetic power generation module is simple, the requirements for structural processing accuracy are relatively low, and the manufacturing, installation, and maintenance costs are all low. Since magnetic repulsion can provide strong power and the use of springs can reduce energy loss, the efficiency of energy conversion may be improved. Furthermore, the present device does not rely on fossil fuels or limited resources and is a clean energy conversion method. The number of connecting rods and magnetic power generation modules on the turntable can be increased as needed to improve the power generation capacity.
