DETAILED DESCRIPTION

[0019] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0020] Reference below Figure 1-Figure 4 The protection assembly 10 for a kinetic flywheel 11 according to an embodiment of the present invention is described, including: a housing 100 and a protection portion 200 .

[0021] Specifically, a accommodating space 110 is formed in the shell 100, the kinetic flywheel 11 is arranged in the accommodating space 110, and a recovery groove 124 is provided on the shell 100; the protective part 200 is constructed on the inner circumferential wall of the shell 100, and the protective part 200 is arranged on the outside of the kinetic flywheel 11, and the protective part 200 is arranged opposite to the recovery groove 124; wherein, the protective part 200 includes a plurality of protective groups 210, and the plurality of protective groups 210 are circumferentially arranged on the outside of the kinetic flywheel 11, and the debris generated by the kinetic flywheel 11 during use acts on the plurality of protective groups 210 for multiple buffering and sedimentation.

[0022] It should be noted that during the use of the kinetic flywheel 11, it is suitable for transferring energy to the kinetic flywheel 11 for storage. During the use of the kinetic flywheel 11 under extreme working conditions, it is suitable for generating debris fragments. The debris fragments are suitable for being thrown out by the kinetic flywheel 11 and acting on the inner peripheral wall of the shell 100, which may cause the fragments to collide and rebound with the shell, and thus may collide with the rotor twice or even multiple times, resulting in a large amount of instantaneous fragmentation of the high-speed rotor and an instantaneous structural fragmentation energy burst. Therefore, how to buffer the debris to reduce the impact on the inner peripheral wall of the shell 100 is crucial. At the same time, during long-term use, the accumulation of debris will affect the use of the kinetic flywheel 11, so how to buffer and store the debris is very necessary. At the same time, the materials used in the production process of the kinetic flywheel 11 are relatively expensive. If they are recycled and used, the cost can be significantly reduced. However, how to recycle and reuse them is a problem that needs to be solved.

[0023] The present application provides a protective assembly 10 for a kinetic flywheel 11, which is adapted to include: a housing 100 and a protective portion 200. The housing 100 is adapted to provide a receiving space 110, so that the kinetic flywheel 11 can be arranged in the receiving space 110 as designed, and when the kinetic flywheel 11 is operating and storing energy, it is adapted to convert the transferred energy into kinetic energy for storage. The debris generated by the kinetic flywheel 11 during use in the present application is adapted to act on the protective portion 200 for buffering, so as to prevent the debris from directly acting on the housing 100 and colliding, thereby improving the reliability of the housing 100.

[0024] Specifically, a accommodating space 110 is suitable for being constructed in the shell 100 so that the kinetic flywheel 11 can be arranged in the accommodating space 110. The accommodating space 110 is suitable for providing space for the rotation of the kinetic flywheel 11 so that the kinetic flywheel 11 can rotate and store energy as designed. A protective portion 200 is provided on the inner peripheral wall of the shell 100. Since the protective portion 200 is arranged on the outer peripheral side of the kinetic flywheel 11, the debris generated by the kinetic flywheel 11 during use will collide with the protective portion 200 after being thrown out by the kinetic flywheel 11. The protective portion 200 has a buffering and sedimentation effect, which prevents the fragments of the kinetic flywheel 11 from colliding with the shell 100 after the kinetic flywheel 11 fails to break down under extreme working conditions, thereby improving safety.

[0025] Furthermore, a recovery groove is provided at the bottom of the shell 100 relative to the protection group 210 to guide the debris buffered and guided by the protection group 210 to the recovery groove for collection and recovery, thereby facilitating subsequent recycling and reuse, thereby reducing the cost of use.

[0026] In some specific embodiments, the protection portion 200 is suitable for including a plurality of protection groups 210, and the plurality of protection groups 210 are arranged on the outer peripheral side of the kinetic flywheel 11 in an axially spaced manner, so that the fragments generated after the kinetic flywheel 11 is decomposed can be buffered by the protection group 210 when being thrown out in the circumferential direction. Since the protection group 210 can buffer and settle the fragments and debris, the fragments are prevented from hitting the shell 100, thereby achieving improved safety and reliability.

[0027] According to the embodiment of the present invention, the protective assembly 10 for the kinetic flywheel 11 is constructed with a protective portion 200 in the housing 100. Since the protective portion 200 is arranged on the outside of the kinetic flywheel 11 in a circumferentially spaced manner, the debris generated during the use of the kinetic flywheel 11, or the fragments generated by the kinetic flywheel 11 due to cracking, can be buffered and settled by the protective portion 200 to prevent the debris from impacting the housing 100, thereby improving the safety and reliability of use. In addition, by arranging the protective portion 200 relative to the recovery tank 124, the debris buffered and recovered by the protective portion 200 can be directed to the recovery tank 124 for recycling and reuse, effectively reducing costs.

[0028] In some embodiments, each of the plurality of protection groups 210 includes a first protection layer 211, a second protection layer 212, and a third protection layer 213. The first protection layer 211, the second protection layer 212, and the third protection layer 213 are sequentially sleeved from the inside outward on the outside of the kinetic energy flywheel 11. In other words, by circumferentially arranging the plurality of protection groups 210 on the outside of the kinetic energy flywheel 11 and aligning the structures of the plurality of protection groups 210, the assembly process of the protection assembly 10 is simplified and efficient, thereby improving production efficiency. In some specific embodiments, the protection group 210 includes: a first protection layer 211, a second protection layer 212 and a third protection layer 213. Since the first protection layer 211, the second protection layer 212 and the third protection layer 213 are arranged in sequence on the outside of the kinetic flywheel 11, the debris of the kinetic flywheel 11 can act on the first protection layer 211, the second protection layer 212 and the third protection layer 213 in sequence for buffering. Multiple buffering can reduce the impact and prevent the debris from hitting the shell 100, thereby improving reliability.

[0029] In some embodiments, the first protective layer 211 is a plastic energy-absorbing protective layer, the second protective layer 212 is a flexible energy-absorbing protective layer, and the third protective layer 213 is a magnetic buffering protective layer. Specifically, the first protective layer 211 is configured as a plastic energy-absorbing protective layer so that it can capture the initial impact fragments, thereby absorbing more of the impact of the debris fragments and reducing the subsequent impact of the debris fragments after they pass through the first protective layer 211. Similarly, the second protective layer 212 is configured as a flexible energy-absorbing protective layer so that the debris fragments are able to act on the second protective layer 212 after passing through the first protective layer 211. The second protective layer 212 is configured as a flexible energy-absorbing protective layer so that it can further absorb the kinetic energy of the debris fragments and constrain them. In addition, the third protective layer 213 is a magnetic buffer protective layer so that the magnetic field generated by the third protective layer 213 can magnetically repel and guide the debris, thereby absorbing the remaining kinetic energy as much as possible. At the same time, the magnetic field also guides and collects the debris to avoid the impact of the debris on the shell 100, and the magnetic field can also transfer the debris to the recovery tank 124 for storage and collection, which is convenient for recycling and reduces costs.

[0030] In some embodiments, a plurality of limiting grooves 120 are circumferentially spaced apart on the circumferential wall of the housing 100. The limiting grooves 120 are arranged opposite to the protective portion 200, and the protective portion 200 is correspondingly arranged in the limiting grooves 120. It is understood that the limiting grooves 120 provided on the inner circumferential wall of the housing 100 are suitable for providing a position for the assembly of the protective portion 200, so that the protective portion 200 can be arranged in the limiting grooves 120 as designed, thereby allowing the protective portion 200 to buffer and settle debris of the kinetic flywheel 11 as designed, thereby improving safety.

[0031] In some embodiments, the limiting groove 120 includes, from the inside to the outside, a first mounting groove 121, a second mounting groove 122, and a third mounting groove 123. The first protective layer 211 is inserted into the first mounting groove 121, the second protective layer 212 is inserted into the second mounting groove 122, and the third protective layer 213 is provided in the third mounting groove 123. In other words, the limiting groove 120 is suitable for being provided with the first mounting groove 121, the second mounting groove 122, and the third mounting groove 123. The first mounting groove 121 is suitable for providing a position for the first protective layer 211, so that the first protective layer 211 can be assembled in the first mounting groove 121 as designed. At the same time, the use of a plug-in installation method can simplify the assembly process and improve assembly efficiency. Similarly, the second mounting groove 122 is suitable for providing a position for the assembly of the second protective layer 212, so that the second protective layer 212 can be assembled into the second mounting groove 122 as designed. Moreover, the third mounting groove 123 can provide space for the magnetic field generated by the third protective layer 213, so that the magnetic field can buffer and guide the debris to settle, thereby guiding the debris to the recovery groove, thereby improving the safety of the protective component 10 while facilitating the recycling and reuse of materials and reducing the cost of use.

[0032] In some embodiments, the third protective layer 213 includes a plurality of vertically spaced magnetic bodies 214, which are fixedly mounted on the outer peripheral wall of the housing 100. The magnetic field generated by the plurality of magnetic bodies 214 is within the third mounting groove 123. It is understood that the third protective layer 213 is suitable for including a plurality of magnetic bodies 214, which are disposed on the outer peripheral wall of the housing 100, so that the magnetic field formed by the plurality of magnetic bodies 214 can be formed within the third mounting groove 123. This allows the magnetic field to absorb and buffer the energy of debris as designed, reducing or even preventing contact and collision between the debris and the housing 100, thereby improving reliability. At the same time, the magnetic field generated by the magnetic bodies 214 can guide the debris and guide it into the recovery groove provided in the corresponding protective portion, thereby simplifying the recovery process and reducing usage costs.

[0033] In some embodiments, the vertical magnetic field density of the upper magnetic body 214 is less than that of the lower magnetic body 214. By making the magnetic field density of the upper magnetic body 214 less than that of the lower magnetic body 214, the magnetic field formed by the third protective layer 213 forms a gradient magnetic field with a high density at the top and a low density at the bottom. This gradient magnetic field can guide debris downward as designed, preventing it from re-contacting the kinetic flywheel 11 and providing increased safety. Debris can also be directed to the recovery tank 124 for collection, minimizing operational impacts and facilitating the recycling and reuse of kinetic flywheel debris, thereby reducing operational costs.

[0034] In some specific embodiments, the magnetic body 214 is a permanent magnet. This allows the magnetic body 214 to provide a stable magnetic field to drive the debris to settle and be collected, thereby preventing the debris from affecting the operation of the kinetic flywheel 11 and improving its reliability. It also generates a stable magnetic field to guide the debris into the recovery tank 124, recovering valuable materials and reducing operating costs.

[0035] In some embodiments, the vertical projection of the housing 100 is a regular polygon. Thus, by setting the vertical projection of the housing 100 to be a regular polygon, the number of sides of the regular polygon can be the same as the number of the plurality of protection groups 210, so that the plurality of protection groups 210 can be arranged circumferentially outside the kinetic flywheel 11 according to the design, thereby settling and collecting debris generated during use of the kinetic flywheel 11, and improving the reliability of the protection assembly 10.

[0036] The energy storage device according to an embodiment of the present invention includes: a protective assembly 10 for a kinetic flywheel 11 as described above. In this way, since the protective assembly 10 as described above is provided in the energy storage device, and a protective portion 200 is constructed in the shell 100, and the protective portion 200 is arranged on the outside of the kinetic flywheel 11 in a circumferentially spaced manner, the debris generated during use of the kinetic flywheel 11, or the fragments generated due to the cracking of the kinetic flywheel 11, can be buffered and settled by the protective portion 200 to avoid the debris from hitting the shell 100, thereby improving the safety and reliability of the energy storage device. In addition, by arranging the protective portion 200 relative to the recovery tank 124, the debris buffered and recovered by the protective portion 200 can be directed to the recovery tank 124 for easy recycling and reuse, thereby effectively reducing costs.
