Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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 this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0029] like Figures 1 to 9 As shown, this application provides a ring-shaped magnetic energy storage device, including: a device body 100, comprising an assembly disk 10, an energy charging device 20, an energy discharging device 30, a coaxial transmission device 40, and a non-coaxial transmission device 50. The assembly disks 10 are arranged in an array, the energy charging device 20 is located at one end of the assembly disk 10, the energy discharging device 30 is located at one end of the assembly disk 10, the coaxial transmission device 40 is located in the middle of two sets of assembly disks 10, and the non-coaxial transmission device 50 is located at one end of the assembly disk 10. The assembly disk 10 includes an upper disk 11 and a lower disk 12. A connecting post 13 is provided on one side of both the upper disk 11 and the lower disk 12. An upper magnet group 111 and a lower magnet group 121 are provided at the upper end of the connecting post 13.
[0030] After adopting the above technical solution, since the assembly disk 10 includes an upper disk 11 and a lower disk 12, and each of the upper disk 11 and the lower disk 12 is provided with a connecting post 13, and the upper end of the connecting post 13 is provided with an upper magnet assembly 111 and a lower magnet assembly 121, a mechanical energy storage method that can use magnetic force to store energy can solve the problem that existing storage methods all have their advantages and disadvantages. In summary, there is a lack of an energy storage method that can simultaneously possess the characteristics of being unaffected by the environment, long-term energy storage, low price, long life, and safety.
[0031] It should be noted that there is a phenomenon of opposite poles attracting and like poles repelling among the magnets inside the upper magnet group 111 and the lower magnet group 121. If we compare the magnetic field to a gravitational field, the attractive and repulsive forces of the magnets to gravity, and the energy possessed by the magnets due to their positional relationship to magnetic potential energy (analogous to gravitational potential energy), then we can consider that when two magnets with opposite poles are placed at a greater distance, their magnetic potential energy is greater than when they are placed closer together. Similarly, if two magnets with like poles are placed at a greater distance, their magnetic potential energy is less than when they are placed closer together. Similar to pumped hydro storage, which uses gravitational potential energy for energy storage, magnetic potential energy can be used for energy storage.
[0032] It should be noted that, as shown in the appendix Figure 6As shown, the upper magnet group 111 and the lower magnet group 121 are placed around a center. The four magnets numbered lower magnet 1211, lower magnet 212, lower magnet 313, and lower magnet 414 form a group, called group A; the four magnets numbered upper magnet 1111, upper magnet 2112, upper magnet 3113, and upper magnet 4114 form a second group, called group B. The relative positions of the magnets in groups A and B remain unchanged within their respective groups. If the positions of the magnets in group A remain unchanged, the magnets in group B can rotate around the center within a certain range. For example, upper magnet 1111 can only meet lower magnet 1211 at most when rotating clockwise, and can only meet lower magnet 212 at most when rotating counterclockwise.
[0033] As attached Figure 5 As shown, without any external force applied, the upper magnet 1111 and the lower magnet 1212 are attracted by their opposite poles, while the upper magnet 1111 and the lower magnet 1212 are repelled by their like poles. The entire group of magnets in group B will rotate counterclockwise to its limit position. At this point, the magnetic potential energy of group B magnets within group A magnets is at its minimum. Applying an external force to group B magnets, causing them to rotate clockwise to their limit position, results in... Figure 7 As shown, at this time, the magnetic potential energy of the B group magnets in the A group magnets is the greatest;
[0034] Appendix Figure 7 The state is the charging state of the two sets of magnets. Figure 5 The state is in the energy release state; using an external force to rotate the B group of magnets clockwise (i.e., from...) Figures 5 to 7 Then, a certain mechanical device is used to maintain the position of group B magnets, which is the charging process; after releasing the aforementioned device that holds the position of group B magnets, group B magnets rotate counterclockwise under the action of the magnetic field (i.e., from the top). Figures 7 to 5 The process of connecting this motion to an external power generation device or power unit is called the energy release process.
[0035] In an optional embodiment, the upper magnet assembly 111 includes upper magnet one 1111, upper magnet two 1112, upper magnet three 1113, and upper magnet four 1114 located at the upper end of the connecting post 13. The number of upper magnet one 1111, upper magnet two 1112, upper magnet three 1113, and upper magnet four 1114 is equal to the number of upper magnet assemblies 111. The positional relationship of upper magnet one 1111, upper magnet two 1112, upper magnet three 1113, and upper magnet four 1114 is determined according to the appendix. Figure 5 , 6 The figure shown in 7 is just for illustration. As long as a clear attraction and repulsion force can be generated between the magnets, the vertical position of the magnets can be placed arbitrarily.
[0036] In an optional embodiment, the lower magnet group 121 includes lower magnet one 1211, lower magnet two 1212, lower magnet three 1213 and lower magnet four 1214 located at the upper end of the connecting post 13. The upper disk 11, the lower disk 12 and the connecting post 13 form an upper and lower disk. The disk array formed by the three disk groups has magnets interlocked on the front of each disk. Depending on the interlocking position, the rotation direction during energy charging and discharging is also different. The back of the disk is physically connected and fixed to the back of the adjacent disk.
[0037] It should be noted that the appendix Figure 1 As shown, there are four queues, each with three layers of assembly trays (10 groups). The charging device 20 can be an electric motor or other mechanical device, and the discharging device 30 can be a generator (converting to electrical energy) or other mechanical device. A braking device 2 32 can be added between the discharging device 30 and the 10 groups of assembly trays. When discharging is not required, the braking device 2 32 can lock the 10 groups of assembly trays to retain energy. A braking device can also be added to the transmission device for control during charging or discharging.
[0038] The charging or discharging speed and power; the charging device 20 and the discharging device 30 can be divided into a stator part and a rotor part. The rotors of the charging device 20 and the discharging device 30 are respectively connected to the end disks at both ends of the energy storage device. The stator parts of the charging device 20 and the discharging device 30 remain relatively stationary. For example, the stators of the charging device 20 and the discharging device 30 are both connected to the outer casing or the same fixed device.
[0039] Note: Figure 1 The charging device 20 and the discharging device 30 shown are for illustrative purposes only. In actual use, their positions can be interchanged or they can be combined into one.
[0040] The number of discs in each of the 10 groups of assembly trays can be set as needed; the total number of the 10 groups of assembly trays can also be set as needed; the number and position of the coaxial transmission device 40, the non-coaxial transmission device 50, the second braking device 32, and the first braking device 23 can also be set according to actual needs; they can be flexibly set as needed, and different settings do not affect the creativity of this case.
[0041] In an optional embodiment, the charging device 20 includes a motor 21, a one-way bearing 22, a braking device 23, and a reducer 24.
[0042] It should be noted that, according to the appendix Figure 8In this example, the number and position of the electric motor 21, the one-way bearing 22, and the braking device 23 can be set according to actual needs; this charging device 20 is just one type of charging device among many, and does not deviate from this case due to the different charging devices 20. For example, the end disc can be directly connected to the rotor of a wind turbine, steam turbine, or internal combustion engine without the need for an electric motor.
[0043] In an optional embodiment, the energy dissipation device 30 includes a generator 31, a braking device 32, and a speed increaser 33.
[0044] It should be noted that, according to the appendix Figure 9 The device consists of a basic energy release device 30, which converts the energy stored in the assembly discs 10 into electrical energy. When energy release is not required, the braking device 2 32 is locked; when energy release is needed, the braking device 2 32 is released, causing the assembly discs 10 to drive the speed increaser 33, which in turn drives the generator 31, thus converting the energy stored in the device into electrical energy. The number and position of the braking device 2 32 and the speed increaser 33 can be set according to actual needs. The energy release device 30 can take many forms; this design is simply a basic, simple energy release device 30, and the design concept is not affected by the different energy release devices 30. For example, the end discs can be connected to the wheels to directly convert energy into mechanical energy.
[0045] In one optional embodiment, the number of connecting posts 13 is several groups and they are arranged in an array, and the several groups of connecting posts 13 are respectively fixedly connected to the upper disk 11 and the lower disk 12.
[0046] It should be noted that, as shown in the appendix Figure 2 As shown, four queues, each with 3 layers of assembly disks and 10 groups, are connected in series and then in parallel to the charging device 20 and the discharging device 30; the non-coaxial transmission device 50 can move multiple disks simultaneously at one end while the other end moves.
[0047] In an optional embodiment, the geometry of the upper disk 11 and the lower disk 12 includes, but is not limited to, any one of a circle, a regular polygon, or a rhombus.
