Description

Technical Field

[0001] This utility model relates to the field of mounting base technology, and in particular to a vibration-proof mounting base for a flywheel energy storage device. Background Technology

[0002] A flywheel energy storage device is a mechanical device that uses a high-speed rotating flywheel (rotor) to store and release energy. Its core principle is to convert electrical energy into mechanical energy (kinetic energy) for storage, and then convert the kinetic energy back into electrical energy for output when needed. It typically consists of a rotor, magnetic levitation or mechanical bearings, a housing, and a motor / generator unit.

[0003] Currently, flywheel energy storage devices are typically fixed directly to a concrete foundation or steel structure platform using rigid anchor bolts during installation. In some projects, ordinary rubber pads, spring dampers, or simple vibration isolation blocks are added under the base to reduce the impact of operating vibrations on the surrounding structure.

[0004] However, existing anti-vibration measures have obvious drawbacks: First, rigid connections cannot effectively isolate low-frequency vibrations, but instead create strong coupling between the flywheel and the foundation, which can easily induce structural resonance; second, traditional vibration isolation elements only provide buffering in one direction, such as vertical rubber pads which have almost no ability to suppress horizontal swaying and lack energy dissipation mechanisms, resulting in repeated reflection and amplification of vibrations. Therefore, we propose an anti-vibration mounting base for a flywheel energy storage device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vibration-proof mounting base for a flywheel energy storage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vibration-damping mounting base for a flywheel energy storage device includes a base, two arc-shaped side plates fixedly connected to the top of the base, a rubber pad fixedly connected between the two arc-shaped side plates, a bracket fixedly embedded in the top of the rubber pad, an oil seat with the same hollow structure fixedly connected to the top of the rubber pad and the bracket, an oil inlet pipe and an oil outlet pipe fixedly connected to each other on the left outer wall of the oil seat, a buffer assembly provided inside the oil seat, and a U-shaped rubber sealing sleeve fixedly connected to the top of the oil seat.

[0007] Preferably, the buffer assembly includes a rectangular piston, the inner wall of the oil seat is slidably connected to the outer wall of the rectangular piston, the outer wall of the rectangular piston is evenly provided with a plurality of buffer oil holes, a hollow rectangular column is fixedly embedded in the outer wall of the rectangular piston, a mounting seat is fixedly connected to the top of the rectangular column, the inner wall of the U-shaped rubber sealing sleeve is slidably connected to the outer wall of the rectangular column, and the U-shaped structure of the U-shaped rubber sealing sleeve forms a reliable sliding seal, effectively preventing hydraulic oil leakage in the oil seat.

[0008] Preferably, the outer wall of the base is provided with multiple foot holes evenly distributed. The foot holes can be used with existing foot nails to quickly and firmly fix the base to the foundation, making installation convenient and the fixation reliable.

[0009] Preferably, both the inlet and outlet pipes are threaded with plugs on their outer walls. The plugs have reliable sealing performance and can effectively prevent hydraulic oil leakage from the oil seat.

[0010] Preferably, the top of the oil seat has a rectangular hole, the inner wall of the rectangular hole is slidably connected to the outer wall of the rectangular column, and the rectangular hole assists the rectangular column in moving up and down.

[0011] Preferably, the top of the mounting base has multiple mounting holes, which can be used with bolts and nuts to quickly and firmly fix the flywheel energy storage device body to the mounting base.

[0012] Compared with the prior art, the advantages of this utility model are: This solution dissipates the energy of flywheel vibration and suppresses vibration transmission by using the oil throttling damping formed by the rectangular piston and buffer oil hole; at the same time, the rubber pad and arc-shaped side plate provide multi-dimensional elastic support, effectively absorbing horizontal and torsional vibration components, avoiding the limitations of traditional unidirectional vibration reduction, and its sealing structure (return-shaped rubber sealing sleeve) ensures the long-term reliable operation of the oil.

[0018] Depend on Figures 1-4 As shown, a vibration-damping mounting base for a flywheel energy storage device is disclosed, comprising a base 1. The outer wall of the base 1 is evenly provided with multiple foot holes 2. The foot holes 2 can be used with existing foot nails to quickly and firmly fix the base 1 to the foundation, making installation convenient and reliable. The top of the base 1 is fixedly connected to two arc-shaped side plates 3. The arc-shaped structure of the arc-shaped side plates 3 has excellent anti-deformation ability and elastic support performance, which can provide lateral limiting and elastic support for the rubber pad 4 and the oil seat 6 above, effectively suppressing horizontal vibration and swaying, and making up for the shortcomings of single vertical vibration reduction.

[0019] A rubber pad 4 is fixedly connected between the two arc-shaped side plates 3. The rubber pad 4 has good elasticity and damping performance, which can absorb part of the vibration energy transmitted to the base and weaken the vibration transmission. A bracket 5 is fixedly embedded on the top of the rubber pad 4. The top of the rubber pad 4 and the bracket 5 are fixedly connected to the same hollow oil seat 6. The hollow structure of the oil seat 6 provides sufficient space for hydraulic oil storage and sliding of the rectangular piston 10, ensuring the normal operation of the hydraulic vibration damping mechanism.

[0020] The oil seat 6 has an oil inlet pipe 7 and an oil outlet pipe 8 fixedly connected on the left outer wall. The oil outlet pipe 8 facilitates the rapid discharge of aged and contaminated hydraulic oil from the oil seat 6, enabling oil replacement. Both the oil inlet pipe 7 and the oil outlet pipe 8 have plugs 9 threaded on their outer walls.

[0021] A U-shaped rubber sealing sleeve 15 is fixedly connected to the top of the oil seat 6. The inner wall of the U-shaped rubber sealing sleeve 15 is slidably connected to the outer wall of the rectangular column 12. The U-shaped structure of the U-shaped rubber sealing sleeve 15 forms a reliable sliding seal, which effectively prevents the hydraulic oil in the oil seat 6 from leaking, and at the same time blocks external dust and debris from entering the oil seat 6 and contaminating the oil.

[0022] The oil seat 6 is equipped with a buffer assembly, which includes a rectangular piston 10. The inner wall of the oil seat 6 is slidably connected to the outer wall of the rectangular piston 10. The outer wall of the rectangular piston 10 is evenly provided with multiple buffer oil holes 11. The rectangular piston 10 can slide up and down in the oil seat 6 with vibration, squeezing the internal hydraulic oil and generating a throttling damping force in conjunction with the buffer oil holes 11.

[0023] A hollow rectangular column 12 is fixedly embedded in the outer wall of the rectangular piston 10. The hollow structure of the rectangular column 12 reduces the load on the rectangular piston 10 while providing sufficient rigidity to support the weight of the mounting base 13 and the flywheel device. A rectangular hole is provided on the top of the oil seat 6. The inner wall of the rectangular hole is slidably connected to the outer wall of the rectangular column 12. The mounting base 13 is fixedly connected to the top of the rectangular column 12. The top surface of the mounting base 13 is flat, which can provide a stable mounting platform for the flywheel energy storage device body and ensure that the device is installed firmly. Multiple mounting holes 14 are provided on the top of the mounting base 13.

[0024] Working principle: First, the base is fixed to the foundation through multiple foot holes 2 on the base 1 and existing foot nails. The flywheel energy storage device body is installed on the mounting base 13 and fixed through multiple mounting holes 14 with bolts and nuts. When the flywheel rotates at high speed and generates vibration, the vibration is transmitted to the mounting base 13 and drives the rectangular column 12 and the rectangular piston 10 fixed thereon to slide up and down in the oil seat 6. When the rectangular piston 10 slides, it squeezes the hydraulic oil filled in the oil seat 6, forcing the oil to flow through multiple buffer oil holes 11 evenly opened on its outer wall. The throttling effect of the oil holes generates damping force and consumes vibration energy. Meanwhile, the rubber pad 4 and the two arc-shaped side plates 3 provide lateral elastic support to help absorb vibration components; the oil seat 6 is fixed to the rubber pad 4 by the bracket 5 to further enhance the overall flexibility and vibration isolation effect. The oil can be replenished through the oil inlet pipe 7 or replaced through the oil outlet pipe 8. Normally, it is sealed by the plug 9. When the rectangular column 12 slides, the U-shaped rubber sealing sleeve 15 maintains a sliding seal with its outer wall to prevent oil leakage and dust intrusion.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
