[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments 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.

[0027] A five-degree-of-freedom magnetic levitation flywheel energy storage device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, an embodiment of the present invention provides a five-degree-of-freedom magnetic levitation flywheel energy storage device, comprising: a housing 1 and a flywheel rotor 6, a magnetic levitation bearing 7, a motor rotor 10, and a mounting mechanism 8. The flywheel rotor 6 is disposed inside the housing 1, the magnetic levitation bearing 7 is sleeved on the outer wall of the flywheel rotor 6, the motor rotor 10 is disposed on the inner wall of the housing 1, and the mounting mechanism 8 comprises a protective block 81, a slider 82, a fixing ring 84, and a fixing block 85. The protective block 81 is installed inside the housing 1, the slider 82 is fixed on the inner wall of the housing 1, the outer wall of the slider 82 has a groove 83, and the fixing ring 84 is sleeved on the outer wall of the flywheel rotor 6.

[0029] The outer wall of the protective block 81 is fixed with a fixing block 85, and the fixing block 85 and the sliding groove 83 form a sliding structure.

[0030] Specifically, when the flywheel rotor 6 rotates at high speed inside the housing 1, the protective block 81 slides within the groove 83 via the fixing block 85, providing stable support for the flywheel rotor 6. Simultaneously, the fixing ring 84 further limits the movement of the flywheel rotor 6, ensuring its stability during rotation. Furthermore, the use of the magnetic levitation bearing 7 allows the flywheel rotor 6 to rotate without contact, significantly reducing frictional losses during rotation and improving the operating efficiency and service life of the flywheel energy storage device.

[0031] In one embodiment of this application, such as Figure 2 As shown, the outer wall of the outer casing 1 is provided with a sealing component 9. The sealing component 9 includes a locking ring 91 and a first sealing ring 92. The locking ring 91 is fixed to the bottom wall of the outer casing 1, and the first sealing ring 92 is sleeved on the inner wall of the locking ring 91.

[0032] Understandably, the inclusion of the first sealing ring 92 effectively improves the sealing performance between the outer casing 1 and the locking ring 91, preventing external dust or liquid from entering the device and ensuring its safety and stability. Simultaneously, the use of the locking ring 91 facilitates the fixing and installation of the first sealing ring 92, improving the assembly efficiency and convenience of the device.

[0033] In one embodiment of this application, such as Figure 1 As shown, an exhaust pipe 2 is provided on the outer casing 1.

[0034] Understandably, the exhaust pipe 2 is designed to effectively expel the heat and gas generated inside the device, preventing the vacuum operation of the device from being affected by excessive internal temperature or excessive gas pressure.

[0035] In one embodiment of this application, such as Figure 1 As shown, a base 3 is provided on the bottom wall of the outer casing 1.

[0036] Understandably, the base 3 provides stable support for the entire device, ensuring its stability and safety during operation.

[0037] In one embodiment of this application, such as Figure 1 As shown, the outer casing 1 has an external pipe connected to a liquid storage tank 4.

[0038] Understandably, the storage tank 4 is designed to store and provide lubricating fluid, which can be used for cooling and lubrication to meet the operational requirements of the flywheel energy storage device.

[0039] In one embodiment of this application, such as Figure 1 As shown, an infusion pipe 5 is fixed on the storage tank 4.

[0040] Understandably, the infusion pipe 5 facilitates the delivery of lubricating fluid from the storage tank 4 to the parts that require lubrication or cooling, thus ensuring the normal operation of the flywheel energy storage device.

[0041] In one embodiment of this application, such as Figure 5 As shown, the liquid storage tank 4 is equipped with a filtration mechanism 11. The filtration mechanism 11 includes a filter shell 111, a spring 112, a fixed shell 113, and a filter cylinder 114. The filter shell 111 is fixed to the inner wall of the liquid storage tank 4, the spring 112 is fixed inside the filter shell 111, the fixed shell 113 is connected to the other end of the spring 112, and the filter cylinder 114 is installed on the inner wall of the fixed shell 113.

[0042] Specifically, when the lubricating fluid passes through the storage tank 4, it first passes through the filter cartridge 114. The filter cartridge 114 effectively removes impurities and particulate matter from the lubricating fluid, ensuring its cleanliness. Simultaneously, the spring 112 allows the filter cartridge 114 to undergo elastic deformation when impacted by the lubricating fluid, thus buffering the impact and extending its service life. Furthermore, the fixing shell 113 is connected to the other end of the spring 112, further securing the position of the filter cartridge 114 and ensuring its stability.

[0043] In one embodiment of this application, such as Figure 2 As shown, the outer wall of the storage tank 4 is fitted with a third sealing ring 12.

[0044] Understandably, the installation of the third sealing ring 12 further improves the sealing performance between the liquid storage tank 4 and the outer shell 1 or other connecting parts, effectively preventing the leakage of lubricating fluid and ensuring the normal operation of the internal lubrication system of the device.

[0045] In one embodiment of this application, such as Figure 1 As shown, the outer wall of the infusion tube 5 is fitted with a second sealing ring 93.

[0046] Understandably, the second sealing ring 93 enhances the sealing between the infusion tube 5 and the connecting parts, preventing leakage of lubricating fluid during delivery.

[0047] Working Principle: In operation, the flywheel rotor 6 is first installed inside the housing 1 and supported by the magnetic levitation bearing 7, achieving contactless rotation. The motor rotor 10 is mounted on the inner wall of the housing 1 to drive the flywheel rotor 6 to rotate at high speed, thereby storing energy. The mounting mechanism 8 ensures greater stability of the flywheel rotor 6 during installation and operation. The protective block 81 slides within the groove 83 via the fixing block 85, providing stable support for the flywheel rotor 6. Simultaneously, the fixing ring 84 limits the movement of the flywheel rotor 6, ensuring its stability during rotation. When the flywheel energy storage device is running, heat and gas may be generated internally. The exhaust pipe 2 effectively removes this heat and gas, preventing interference with the device's vacuum operation. The base 3 provides stable support for the entire device, ensuring its stability and safety during operation. The storage tank 4 stores and provides lubricating fluid, which is delivered to the parts requiring lubrication or cooling via the delivery pipe 5, meeting the operational needs of the flywheel energy storage device. The filter assembly 11 inside the storage tank 4 filters the lubricating fluid, removing impurities and particulate matter to ensure its cleanliness. Simultaneously, the spring 112 cushions the impact of the lubricating fluid on the filter cartridge 114, extending its service life. Furthermore, the sealing assembly 9, the third sealing ring 12, and the second sealing ring 93 improve the sealing performance between the outer casing 1 and the locking ring 91, between the storage tank 4 and the outer casing 1 or other connecting parts, and between the infusion pipe 5 and the connecting parts, effectively preventing leakage of lubricating fluid or external dust and liquids, ensuring the safety and stability of the device.
