[0001] This invention relates to the technical field of flywheel energy storage devices, and more particularly to a flywheel energy storage device with a five-degree-of-freedom magnetic levitation bearing. Background Technology

[0002] Flywheel energy storage devices are physical energy storage devices based on kinetic energy storage and conversion. They store electrical energy by converting it into the kinetic energy of a high-speed rotating flywheel, and then release the kinetic energy back into electrical energy when needed, thus achieving temporary energy storage and retrieval.

[0003] Traditional flywheel energy storage devices, during energy conversion, utilize a high-speed rotating flywheel containing enormous kinetic energy. This flywheel is prone to breakage due to dynamic imbalance or collisions, causing fragments to fly at extremely high speeds, posing a safety hazard. Currently, the common approach is to reinforce the flywheel material. However, while reinforcing the flywheel material improves structural strength, it lacks protective design for the casing and cannot effectively mitigate the damage caused by flywheel breakage. Therefore, it is still difficult to completely avoid safety hazards caused by dynamic imbalance. Summary of the Invention

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following description, with reference to the accompanying drawings, describes a flywheel energy storage device based on a five-degree-of-freedom magnetic levitation bearing according to an embodiment of the present invention.

[0029] like Figures 1-6 As shown, an embodiment of the present invention provides a flywheel energy storage device for a five-degree-of-freedom magnetic levitation bearing, comprising: a base 1, a body 2, and a reinforcing component 3.

[0030] The body 2 is mounted on the base 1, and the reinforcing component 3 includes a connecting frame 31, a fixing ring 32, a connecting seat 33, a mounting seat 34, and a damping rod 35.

[0031] The connecting frames 31 are respectively set on the base 1, the fixing rings 32 are rotatably connected to the corresponding connecting frames 31, the connecting seats 33 are respectively set on the base 1, the mounting seats 34 are respectively set on the corresponding connecting seats 33, the two ends of the damping rod 35 are respectively connected to the corresponding mounting seats 34, and the damping rod 35 is provided with a first spring 36 on its outside, and the two ends of the first spring 36 are respectively connected to the corresponding mounting seats 34.

[0032] Specifically, when storing excess electrical energy using an energy storage device, the flywheel 23 inside the body 2 will rotate at high speed. The high-speed rotating flywheel 23 contains huge kinetic energy. If the flywheel 23 breaks due to material fatigue, dynamic imbalance failure, or collision, the fragments will fly at extremely high speed, posing a serious safety hazard. At this time, by adding a fixing ring 32 to the outside of the outer shell 21 to reinforce the part where the flywheel 23 is installed, the fragments will be blocked by the fixing ring 32 when the flywheel 23 breaks. The damping rod 35 and the first spring 36 on its outside support and fix the part of the outer shell 21 where the drive component 26 is installed, so as to avoid dynamic imbalance and thus avoid injury to personnel.

[0033] In one embodiment of this application, such as Figure 2 As shown, the body 2 includes an outer shell 21, a suspension support shaft 22, a flywheel 23, a linkage shaft 24, a limiting ring 25, a drive component 26, and a magnet 27.

[0034] The suspension support shaft 22 is located inside the outer shell 21. The flywheel 23 is connected to the other end of the suspension support shaft 22. The linkage shaft 24 is connected to the other end of the flywheel 23. The limiting ring 25 is located inside the outer shell 21. The driving component 26 is located inside the limiting ring 25, and the rotation shaft of the driving component 26 is connected to the other end of the linkage shaft 24. The magnets 27 are respectively located on the inner wall of the limiting ring 25 and the outer wall of the linkage shaft 24.

[0035] It should be noted that the driving component 26 described in this embodiment is a motor, whose main function is to convert energy into electrical energy. At this time, the driving component 26 will switch from motor mode to generator mode, and the flywheel 23 will decelerate under the action of resistance. Its kinetic energy is converted into stable AC or DC power output through the power electronic converter.

[0036] Understandably, excess electrical energy is converted into kinetic energy by the drive component 26, and the flywheel 23 is driven to rotate at high speed via the linkage shaft 24, storing the energy in the form of kinetic energy. When energy needs to be released, the kinetic energy of the flywheel 23 is converted into electrical energy by the drive component 26. At this time, the drive component 26 switches from motor mode to generator mode, and the flywheel 23 decelerates under the action of resistance. Its kinetic energy is converted into stable AC or DC power output through the power electronic converter. At the same time, the flywheel 23 is supported by the suspension support shaft 22, thereby ensuring the dynamic balance of the flywheel 23 during rotation. Meanwhile, the connection between the linkage shaft 24 and the inside of the outer shell 21 is changed to magnetic levitation by the magnet 27, further reducing the energy consumed to overcome resistance during rotation.

[0037] In one embodiment of this application, such as Figure 4 As shown, a vacuum assembly 4 is provided on the body 2. The vacuum assembly 4 includes a housing 41, a sealing cover 42, a connecting pipe 43, and a conveying component 44.

[0038] The housing 41 is fitted over the outer shell 21, the sealing cover 42 is connected to the housing 41, the connecting pipe 43 is installed on the sealing cover 42, and the other end of the connecting pipe 43 passes through the base 1 and is connected to the input end of the conveying component 44. The housing 41 has a connecting hole 45, and a sealing ring 46 is installed in the connecting hole 45. The conveying component 44 is provided with a protective shell 47.

[0039] It should be noted that the conveying component 44 described in this embodiment is a vacuum machine, whose main function is to extract the air contained in the space formed by the housing 41 and the sealing cover 42, thereby ensuring that the machine body 2 can operate in a vacuum environment.

[0040] Specifically, when using the body 2 for energy conversion, gaps may exist on the outer shell 21, which may disrupt the vacuum environment inside the outer shell 21. This would increase the resistance encountered by the flywheel 23 during rotation, thus reducing the energy conversion efficiency. In this case, a sleeve 41 and a sealing cover 42 are added to the outside of the outer shell 21 to seal the outside of the outer shell 21. At the same time, the conveying component 44 extracts the air contained in the space formed by the sleeve 41 and the sealing cover 42 through the connecting pipe 43. Even if there are gaps in the outer shell 21, the outside of the outer shell 21 is still a vacuum environment, thereby eliminating the three major interferences of "resistance, heat, and impurities" caused by air. At the same time, the sealing ring 46 fills the gap between the wiring installed in the connecting hole 45 and the connecting hole 45, thereby achieving a sealing effect.

[0041] In one embodiment of this application, such as Figure 5 As shown, the limiting ring 25 is provided with the mounting component 5.

[0042] The mounting assembly 5 includes a mounting shell 51, a cover plate 52, a second spring 54, and a fixing bolt 55. The mounting shell 51 is disposed on the inner wall of the limiting ring 25, the cover plate 52 is rotatably connected to the limiting ring 25, the limiting ring 25 has a mounting groove 53, the second spring 54 is disposed in the mounting groove 53, the fixing bolt 55 is connected to the other end of the second spring 54, the mounting groove 53 has a first sliding groove 56, and the outer wall of the fixing bolt 55 is provided with a slider 57.

[0043] Specifically, before using the energy storage device for energy conversion, press the fixing bolt 55 to press it into the mounting groove 53, and at the same time rotate the cover plate 52 to move the cover plate 52 away from the opening of the mounting shell 51 and put the magnet 27 into the mounting shell 51. Then rotate the cover plate 52 to move the cover plate 52 back to the opening of the mounting shell 51, and at the same time release the fixing bolt 55. Under the action of the second spring 54, the fixing bolt 55 pops upward along the direction of the first sliding groove 56, thereby fixing the position of the cover plate 52. At this time, connect the two ends of the linkage shaft 24 to the flywheel 23 and the drive component 26 respectively, and then the energy conversion work can begin.

[0044] In one embodiment of this application, such as Figure 6 As shown, the drive component 26 is provided with a connecting component 6, which includes a sleeve 61, a third spring 64, a latch 65 and a fixing block 66.

[0045] The sleeve 61 is fitted onto the outside of the rotating shaft of the drive component 26. A second sliding groove 62 is provided inside the sleeve 61, and a mounting hole 63 is provided inside the second sliding groove 62. A third spring 64 is provided inside the mounting hole 63. A retainer 65 is connected to the other end of the third spring 64. A fixing block 66 is provided on the outer wall of the linkage shaft 24. A control ring 67 is fitted onto the outside of the sleeve 61, and the inner wall of the control ring 67 is connected to the outer wall of the retainer 65.

[0046] It should be noted that the second slide groove 62 described in this embodiment is a right-angled groove, and the fixed block 66 is limited by the second slide groove 62 with corners.

[0047] Specifically, when installing the linkage shaft 24 and the drive component 26, one end of the linkage shaft 24 is first connected to the flywheel 23. Then, the fixing block 66 on the outer wall of the other end of the linkage shaft 24 is inserted into the second slide groove 62 in the sleeve 61 installed on the rotating shaft of the drive component 26 and rotated. At the same time, when the fixing block 66 is inserted into the second slide groove 62, the outer wall of the fixing block 66 will press the bolt 65 into the mounting hole 63. When the fixing block 66 rotates, the bolt 65, which is no longer pressed, will be ejected into the second slide groove 62 under the action of the third spring 64, thereby fixing the fixing block 66 in the second slide groove 62.

[0048] Working principle: Excess electrical energy is converted into kinetic energy through the drive component 26, and the flywheel 23 is driven to rotate at high speed through the linkage shaft 24 to store energy in the form of kinetic energy. When energy needs to be released, the kinetic energy of the flywheel 23 is converted into electrical energy through the drive component 26.At this time, the drive unit 26 switches from motor mode to generator mode. The flywheel 23 decelerates under the action of resistance, and its kinetic energy is converted into stable AC or DC power output through the power electronic converter. At the same time, the flywheel 23 is supported by the suspension support shaft 22, thereby ensuring the dynamic balance of the flywheel 23 during rotation. When using the energy storage device to store excess electrical energy, the flywheel 23 inside the body 2 will rotate at high speed. The high-speed rotating flywheel 23 contains huge kinetic energy. If the flywheel 23 breaks due to material fatigue, dynamic imbalance failure, or collision, the fragments will fly at extremely high speed, posing a serious safety hazard. At this time, by adding a fixing ring 32 to the outside of the outer shell 21 to reinforce the part where the flywheel 23 is installed, the flywheel 23 is secured. When the device breaks, the fragments are blocked by the retaining ring 32, and the part of the outer shell 21 where the drive component 26 is installed is supported and fixed by the damping rod 35 and the first spring 36 outside it, so as to avoid dynamic imbalance. When the machine body 2 is used for energy conversion, there may be gaps in the outer shell 21, which may cause the vacuum environment inside the outer shell 21 to be destroyed, thereby increasing the resistance encountered by the flywheel 23 during rotation and reducing the energy conversion efficiency. At this time, a sleeve 41 and a sealing cover 42 are added to the outside of the outer shell 21 to seal the outside of the outer shell 21. At the same time, the conveying component 44 extracts the air contained in the space formed by the sleeve 41 and the sealing cover 42 through the connecting pipe 43. At this time, even if there are gaps in the outer shell 21, The exterior of the outer casing 21 remains a vacuum environment, thus eliminating the three major interferences of air: resistance, heat, and impurities. Simultaneously, the sealing ring 46 fills the gap between the wiring installed in the connection hole 45 and the connection hole 45, achieving a sealing effect. Before using the energy storage device for energy conversion, the fixing bolt 55 is pressed into the mounting groove 53. Simultaneously, the cover plate 52 is rotated to move it away from the opening of the mounting shell 51, and the magnet 27 is placed into the mounting shell 51. Then, the cover plate 52 is rotated back to the opening of the mounting shell 51, and the fixing bolt 55 is released. Under the action of the second spring 54, the fixing bolt 55 pops upward along the direction of the first sliding groove 56, thus repositioning the cover plate 52. Once fixed, connect both ends of the linkage shaft 24 to the flywheel 23 and the drive component 26 respectively, and then the energy conversion work can begin. When installing the linkage shaft 24 and the drive component 26, first connect one end of the linkage shaft 24 to the flywheel 23, and then insert the fixing block 66 on the outer wall of the other end of the linkage shaft 24 into the second slide groove 62 in the sleeve 61 installed on the rotating shaft of the drive component 26 and rotate it. At the same time, when the fixing block 66 is inserted into the second slide groove 62, the outer wall of the fixing block 66 will press the bolt 65 into the mounting hole 63. When the fixing block 66 rotates, the bolt 65, which is no longer pressed, will be ejected into the second slide groove 62 under the action of the third spring 64, thereby fixing the fixing block 66 in the second slide groove 62.
