[0029] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices and elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of this utility model, it should be understood that the terms "first," "second," etc. are used to describe various types of information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information without departing from the scope of this utility model.

[0032] Flywheel energy storage devices store and release energy through a high-speed rotating flywheel. Their operating principle is based on the conversion between mechanical energy and electrical energy. This involves using an electric motor to convert electrical energy into the flywheel's rotational kinetic energy for storage, and then using a generator to convert the flywheel's rotational kinetic energy back into electrical energy for output when needed. The internal structure of a flywheel energy storage device is extremely complex and sophisticated, consisting primarily of several key components, including the flywheel itself, a bearing system, a vacuum chamber, a power electronics converter, and a control system. These components are manufactured with extremely high precision and must operate in an extremely clean and stable environment to ensure efficient and reliable energy conversion and storage. Consequently, the overall cost of a flywheel energy storage device is relatively high.

[0033] During the transportation and handling of flywheel energy storage devices, due to their complex structure and high cost, any improper handling operations, such as significant vibration, impact, or sudden stops, can easily damage their delicate components. Currently, there is a lack of flywheel carriers specifically designed for flywheel energy storage devices on the market. In most cases, transportation relies on traditional logistics equipment or general-purpose handling tools, which lack shock absorption and impact protection, resulting in uncertainties in the safe and stable transportation of flywheel energy storage devices.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a flywheel carrier device, which includes a support platform 10, a plurality of limit members 20 and a plurality of connecting members 30, wherein the support platform 10 is used to carry a flywheel energy storage device 100; the plurality of limit members 20 are provided on the support platform 10, the plurality of limit members 20 surround the geometric center of the support platform 10, and the limit members 20 are used to abut the outer wall of the flywheel energy storage device 100; the plurality of connecting members 30 surround the geometric center of the support platform 10, the first end of the connecting member 30 is connected to the support platform 10, and the second end of the connecting member 30 is used to connect to the outer wall of the flywheel energy storage device 100.

[0035] In this embodiment, the support platform 10 can be a rectangular flat plate structure or a circular flat plate structure. The specific shape of the support platform 10 is not limited. The support platform 10 can be made of a high-strength and high-hardness metal material with sufficient load-bearing capacity to support and place the flywheel energy storage device 100.

[0036] In this embodiment, each limiting member 20 abuts the outer wall of the flywheel energy storage device 100 from each direction surrounding the support platform 10, so as to fix the flywheel energy storage device 100 on the support platform 10 and limit the movement and shaking of the flywheel energy storage device 100 during transportation. The two ends of the connecting member 30 are respectively connected to the edge of the support platform 10 and the outer wall of the flywheel energy storage device 100. Each connecting member 30 pulls the edge of the flywheel energy storage device 100 downward from each direction surrounding the support platform 10, forming a downward pulling force on the flywheel energy storage device 100 from each direction, further fixing the flywheel energy storage device 100 and preventing the flywheel energy storage device 100 from loosening.

[0037] Based on the above technical solution, when transporting the flywheel energy storage device 100, the flywheel energy storage device 100 is first placed on the support platform 10. By adjusting the position of each limiter 20 so that each limiter 20 abuts against the outer wall of the flywheel energy storage device 100, the flywheel energy storage device 100 is fixed from different directions. Then, the length of the connecting member 30 is adjusted according to the height of the flywheel energy storage device 100, the first end of the connecting member 30 is connected to the edge of the support platform 10, and the second end of the connecting member 30 is rotated upward to connect to the outer wall of the flywheel energy storage device 100. In this way, the flywheel energy storage device 100 is fixed to the flywheel carrier. Even if it encounters unexpected situations such as vibration, impact, or sudden stop during transportation, the flywheel energy storage device 100 can be safely and stably fixed to the flywheel carrier, thereby being effectively protected. The flywheel carrier of this embodiment is doubly fixed by the limiting member 20 and the connecting member 30 , thereby improving the stability and safety of the flywheel energy storage device 100 during transportation and preventing damage to the internal structure of the flywheel energy storage device 100 .

[0038] In some embodiments, the upper surface of the support platform 10 is provided with some anti-slip patterns, such as diamond grids, wavy lines or cross lines, etc. The anti-slip patterns can increase the roughness of the upper surface of the support platform 10 and enhance the friction between the flywheel energy storage device 100 and the support platform 10.

[0039] In some embodiments, some anti-slip pads are provided on the upper surface of the support platform 10. The anti-slip pads are made of a material with a high friction coefficient, such as rubber, silicone or polyurethane. The anti-slip pads fit tightly to the bottom of the flywheel energy storage device 100, which can also enhance the friction between the flywheel energy storage device 100 and the support platform 10.

[0040] In some embodiments, as Figure 1 and Figure 2As shown, the flywheel carrier device also includes a platform frame 40 and a shock-absorbing module 50; the platform frame 40 surrounds the supporting platform 10, and the shock-absorbing module 50 is arranged between the platform frame 40 and the supporting platform 10, one end of the shock-absorbing module 50 is connected to the platform frame 40, and the other end of the shock-absorbing module 50 is connected to the supporting platform 10.

[0041] Specifically, the shape and size of the platform frame 40 should be configured accordingly to the shape and size of the support platform 10, and the platform frame 40 surrounds the support platform 10. A shock-absorbing module 50 is connected to the platform frame 40 at one end and to the support platform 10 at the other end. The shock-absorbing module 50 can be connected by bolts, welding, or other fixing methods. The primary function of the shock-absorbing module 50 is to absorb vibration and impact generated during transportation, protecting the flywheel energy storage device 100 from damage.

[0042] The shock absorbing module 50 may include a shock absorbing spring, a rubber shock absorber, a gas shock absorber or a hydraulic shock absorber, etc. The present embodiment does not limit the specific structure of the shock absorbing module 50 as long as it can achieve a shock absorbing effect.

[0043] In some embodiments, as Figure 1 and Figure 2 As shown, the shock-absorbing module 50 includes a plurality of shock-absorbing pads 51, which are arranged at equal intervals around the center of the support platform 10; the height of the support platform 10 is greater than the height of the platform frame 40, one end of the shock-absorbing pad 51 is connected to the platform frame 40, and the other end of the shock-absorbing pad 51 is connected to the support platform 10.

[0044] Specifically, the shock-absorbing pad 51 is typically composed of an air chamber, an elastic diaphragm, a load-bearing plate, and other components. The air chamber absorbs and disperses vibration energy, while the elastic diaphragm provides elasticity and a cushioning effect. The shock-absorbing pad 51 has the ability to elastically deform, quickly adapting to and buffering various vibrations and shocks, thereby ensuring the smooth operation of the flywheel carrier.

[0045] In this embodiment, the number and arrangement of the shock-absorbing pads 51 are designed based on the size and weight of the support platform 10. In this embodiment, multiple shock-absorbing pads 51 are arranged at equal intervals around the center of the support platform 10 to ensure that when the support platform 10 is vibrated, the shock-absorbing module 50 can evenly absorb vibration and impact from all directions, protecting the flywheel energy storage device 100 from damage. The shock-absorbing pads 51 can be cylindrical, conical, or other shapes.

[0046] In this embodiment, because the height of the support platform 10 is greater than that of the platform frame 40, the shock-absorbing pads 51 are arranged at an angled angle. When the flywheel carrier encounters a bumpy or inclined transport surface, the inclined shock-absorbing pads 51 can adapt to the road surface changes and effectively absorb vibration energy. Furthermore, the inclined position of the shock-absorbing pads 51 makes them easier to access during maintenance and replacement. Because the shock-absorbing pads 51 are not positioned completely perpendicular to the ground or the platform frame 40, operators can more easily access the connection of the shock-absorbing pads 51 to perform tasks such as tightening bolts, replacing, or inspecting them.

[0047] Exemplarily, the shock-absorbing module 50 includes eight shock-absorbing pads 51, and the support platform 10 and the platform frame 40 are both square frames, wherein four shock-absorbing pads 51 are arranged in the middle positions of the four sides of the square frame (the gap between the support platform 10 and the platform frame 40), and the other four supports are arranged at the four corner positions of the square frame (the gap between the support platform 10 and the platform frame 40), thereby forming a shock-absorbing effect on the flywheel energy storage device 100 from eight directions.

[0048] This embodiment uses multiple shock-absorbing pads 51 arranged at equal intervals, so that the flywheel carrier can absorb vibration energy more evenly from different directions, reduce the vibration of the flywheel energy storage device 100 during transportation, and improve the safety of the flywheel energy storage device 100.

[0049] In some embodiments, as Figure 2 and Figure 4 As shown, the connecting member 30 includes a connecting rod 33 and a first connecting portion 31 and a second connecting portion 32 respectively provided at both ends of the connecting rod 33. The first connecting portion 31 and the second connecting portion 32 can be extended and fixed along the length direction of the connecting rod 33, thereby adjusting the overall length of the connecting member 30 according to the distance between the connection position of the flywheel energy storage device 100 and the support platform 10, so that the connecting member 30 can pull the flywheel energy storage device 100 downward.

[0050] For example, if the distance between the connection position of the flywheel energy storage device 100 and the connection position between the support platform 10 is large, the first connection portion 31 and the second connection portion 32 are respectively extended from the connecting rod 33 along the length direction of the connecting rod 33 and fixed, thereby increasing the length of the connecting member 30. If the distance between the connection position of the flywheel energy storage device 100 and the connection position between the support platform 10 is small, the first connection portion 31 and the second connection portion 32 are respectively retracted into the connecting rod 33 along the length direction of the connecting rod 33 and fixed, thereby reducing the length of the connecting member 30.

[0051] In some embodiments, as Figure 1 and Figure 2 As shown, the support platform 10 is provided with an eye screw 60 , and the connecting member 30 is a turnbuckle bolt, and the first end of the turnbuckle bolt is connected to the eye screw 60 .

[0052] Specifically, a turnbuckle, also known as a rigging turnbuckle or cable tie, is a type of connection hardware consisting of an adjusting rod, a nut, and a pull rod. The turnbuckle's length is adjusted by a lead screw. The eyebolt 60 consists of a threaded section and a head with an annular hanging hole. The threaded section is threaded into a threaded hole in the support platform 10, while the head protrudes from the surface of the support platform 10 to facilitate the rotational connection of the turnbuckle.

[0053] In this embodiment, the edge of the support platform 10 is provided with multiple eyebolts, and the position of each eyebolt corresponds one-to-one with the position of each connector 30 (or turnbuckle). It should be noted that the flywheel energy storage device 100 is also provided with multiple annularly distributed eyebolts in the middle, and the positions of each connector 30 (or turnbuckle) correspond one-to-one with the position of each connector 30 (or turnbuckle). In this way, the ends of the connector 30 (or turnbuckle) are respectively connected to the eyebolts on the edge of the support platform 10 and the eyebolts on the flywheel energy storage device 100.

[0054] In some embodiments, as Figure 1 and Figure 2 As shown, a plurality of turnbuckles are arranged at equal intervals around the geometric center of the support platform 10 .

[0055] Exemplarily, four eyebolts 60 are respectively provided at the four corner positions of the edge of the support platform 10, and each basket bolt is connected to each eyebolt 60 one by one, and the eyebolts on the flywheel energy storage device 100 are tightened downward from four directions to ensure that the flywheel energy storage device 100 is subjected to uniformly distributed tension from four directions.

[0056] In some embodiments, as Figure 1 and Figure 2 As shown, the limiting member 20 is detachably mounted on the supporting platform 10 , and the limiting member 20 can be adjusted in a direction close to or away from the flywheel energy storage device 100 .

[0057] Specifically, the limiting member 20 is installed on the supporting platform 10 in a detachable connection manner, so that the limiting member 20 can be quickly installed or removed, so as to facilitate maintenance and replacement of the limiting member 20.

[0058] Before transporting the flywheel energy storage device 100, the flywheel energy storage device 100 is first placed stably on the surface of the support platform 10, and then the limiter 20 is adjusted to move closer to the flywheel energy storage device 100 until the limiter 20 contacts the outer wall of the flywheel energy storage device 100, forming a structural physical restriction to ensure the stability of the flywheel energy storage device 100 during transportation. When it is necessary to remove the flywheel energy storage device 100 from the support platform 10, the limiter 20 is adjusted to move away from the flywheel energy storage device 100 until it is completely out of contact with the flywheel energy storage device 100, thereby releasing the restriction and then removing the flywheel energy storage device 100 from the support platform 10.

[0059] In some embodiments, as Figure 3 As shown, the limiting member 20 includes a first limiting portion 21, a second limiting portion 22 and a fastener 23. The first limiting portion 21 extends in the horizontal direction, and the second limiting portion 22 extends in the vertical direction. The first limiting portion 21 and the second limiting portion 22 are integrally formed.

[0060] Among them, the first limiting part 21 and the second limiting part 22 are both provided with fasteners 23, and the fasteners 23 can be screws. The outer wall of the flywheel energy storage device 100 and the support platform 10 are provided with corresponding threaded holes. After the flywheel energy storage device 100 is placed on the upper surface of the support platform 10, the position of the limiting part 20 is adjusted until the fasteners 23 on the first limiting part 21 are aligned with the threaded holes on the support platform 10, and the fasteners 23 on the second limiting part 22 are aligned with the threaded holes on the outer wall of the flywheel energy storage device 100, and then the fasteners 23 are fixed to each threaded hole respectively to fix the flywheel energy storage device 100 on the support platform 10.

[0061] For example, Figure 3 As shown, two fasteners 23 are provided on the first limiting portion 21 , and one fastener 23 is provided on the second limiting portion 22 .

[0062] In some embodiments, as Figure 1 and Figure 2 As shown, the flywheel carrying device includes four limiting members 20 , which are arranged at equal intervals around the center of the supporting platform 10 .

[0063] For example, the positions of the four limiting members 20 correspond one-to-one to the four shock-absorbing pads 51 provided in the middle of the four sides of the square frame. The four limiting members 20 limit the flywheel energy storage device 100 from the front, back, left and right to improve the fixing effect.

[0064] In some embodiments, as Figure 1 and Figure 2 As shown, the limiting member 20 and the connecting member 30 are staggered in the center line direction of the supporting platform 10 .

[0065] Specifically, the support platform 10 and the platform frame 40 form a square frame, four limit members 20 are arranged in the middle positions of the four sides of the square frame, and four connecting members 30 are arranged at the four corner positions of the square frame. The four limit members 20 and the four connecting members 30 simultaneously limit the flywheel energy storage device 100 from different directions of front, back, left and right.

[0066] In some embodiments, as Figure 1 and Figure 2 As shown, the flywheel carrier further includes an anti-skid plate 70 , which is fixed to the bottom surface of the platform frame 40 .

[0067] Specifically, the platform frame 40 is provided with a number of mounting openings 90 for forklifts to insert into. Before transporting the flywheel energy storage device 100, a forklift is used to insert into the mounting openings 90 and lift the flywheel carrier and flywheel energy storage device 100 for transport as a whole. An anti-skid plate 70 is fixed to the bottom surface of the platform frame 40. When the forklift places the flywheel carrier on the ground or other contact surface, the anti-skid plate 70 increases the friction between the flywheel carrier and the contact surface.

[0068] In some embodiments, as Figure 1 As shown, a plurality of support members 80 extending in a vertical direction are provided on the edge of the platform frame 40 , and the support members 80 are used to support another platform frame 40 .

[0069] Specifically, support members 80 extend upward from the four corners of the platform frame 40. When a flywheel carrier is not equipped with a flywheel energy storage device 100, the support members 80 can be used to stack multiple flywheel carriers. Specifically, the support member 80 of one flywheel carrier is inserted into a groove on the bottom surface or corresponding position of another carrier platform. This stacking method saves storage space and facilitates the handling and transportation of multiple flywheel carriers. The support members 80 can be connected to the platform frame 40 using bolts, welding, or other fixing methods.

[0070] In some embodiments, a locking mechanism or snap-fit ​​device may be provided on the support member 80 to further secure the stacked flywheel carriers.
