Description

Technical Field

[0001] This application relates to the field of vibration reduction and noise reduction of substation reactors, and specifically relates to a vibration isolation support for indoor reactors in substation venues and a manufacturing method thereof. Background Art

[0002] Traditional vibration isolation supports mostly use materials such as rubber or springs. Although they have a certain vibration isolation effect, their performance is often limited in high-load and complex vibration environments. At the same time, there are problems such as insufficient durability, poor frequency adaptability, and rapid material aging, making it difficult to meet the requirements of long-term and multi-functional application scenarios. There is no vibration isolation support on the market that uses polystyrene as the main material. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a vibration isolation support for indoor reactors in substation venues and a manufacturing method thereof, which can effectively reduce the vibration and noise caused by operating equipment, and ensure the stable operation of the equipment and the normal use function of the surrounding environment.

[0011] Bonding and Composite Structure Assembly: Apply high-strength adhesive evenly on the upper and lower surfaces of the bearing body. Then, bond an anti-slip rubber layer and a rigid metal plate respectively on the upper surface of the bearing body, and bond a rigid metal plate on the lower surface of the bearing body. Use a press or clamp to apply pressure and let it stand for curing to ensure firm bonding without air bubbles.

[0012] Curing and Surface Treatment: After bonding, place it in a normal temperature environment for curing. According to needs, spray a protective coating to enhance weather resistance and corrosion resistance.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The polystyrene vibration isolation bearing of the present invention effectively solves the vibration problem during equipment operation, enabling the equipment to achieve the designed operation effect; significantly improves the stability and anti-vibration performance of the equipment; the polystyrene vibration isolation bearing adopts a layered structure, which is simple to manufacture and install, and is convenient for maintenance and replacement; it can effectively isolate the vertical vibration generated by equipment operation from the supporting ground, with small vibration peaks and excellent vibration isolation effect; the inside of the bearing is supported by polystyrene, and the load is evenly distributed through rigid metal plates, and the rubber layer is further used to reduce the impact of vibration on the foundation; when the bearing bears vertical vibration, the polystyrene layer dissipates energy through micro-elastic deformation and further reduces vibration through viscoelastic damping characteristics, achieving excellent vibration isolation effect. Description of the Drawings

[0018] The following will describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. It should be noted that: Similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0019] The term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element qualified by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element.

[0020] The object of the present application is to provide a novel polystyrene vibration isolation support for vibration reduction of indoor reactors in substation venues. From bottom to top, it is a rigid metal plate 1, a support body 3 made of polystyrene, an anti-slip rubber layer 2, and a rigid metal plate 1.

[0021] Preferably, for the rigid metal plate 1, Q235B steel is selected, with a thickness generally of 10 mm. It is cut with high precision and finely polished to ensure a smooth and defect-free surface. The rigid metal plate provided above the anti-slip rubber layer is fastened to the reactor by bolts to enhance the stability and reliability of the overall structure. This layer can effectively provide stability between the support and the equipment installation surface, prevent the support from sliding, and has a certain shock-absorbing effect.

[0022] Preferably, for the anti-slip rubber layer, the thickness is 10 mm, and high-elastic rubber material is used. This layer can effectively provide stability between the support and the equipment installation surface, prevent the support from sliding, and has a certain shock-absorbing effect.

[0023] Preferably, for the support body made of polystyrene. The polystyrene vibration isolation pad can significantly absorb vibration energy and reduce the impact of vibration and shock on the floor slab and the surrounding environment by utilizing its unique light weight property and vertical elastic modulus. The height of the support body is generally 100 mm, and its bottom surface is a square with a side length of 200 mm. It adopts a solid design to provide sufficient vertical stiffness.

[0024] Manufacturing process

[0025] Cutting and shaping of the polystyrene support: Use a CNC cutting machine or a hot wire cutting machine to cut EPS into the required shape, and use a sander or manual trimming to finish the cutting edges to ensure a smooth surface.

[0026] Bonding and composite structure assembly: Evenly apply a high-strength adhesive on the surface of the polystyrene, and then bond the rigid metal plate and the anti-slip rubber layer respectively. Use a press or a clamp to apply appropriate pressure and let it stand for curing to ensure firm bonding without bubbles.

[0027] Curing and surface treatment: After bonding, it is cured at room temperature. If necessary, a protective coating (such as polyurethane coating) can be sprayed to enhance weather resistance and corrosion resistance.

[0028] Installation and construction process

[0029] Determine the installation position: Use a laser rangefinder or level to measure the equipment base and the installation area to ensure the accurate installation position of the support. Mark the placement position of the support on the foundation or installation surface to ensure alignment with the bottom of the equipment.

[0030] Equipment foundation treatment: If the ground is uneven, cement mortar or grouting materials can be used for leveling to ensure uniform stress. Drill holes in the foundation with an electric drill for subsequent bolt installation.

[0031] Support installation: Align the bolt holes of the support and the foundation. Insert high-strength expansion bolts or embedded bolts and tighten them with a torque wrench. Ensure uniform stress on the bolts and avoid local extrusion of the support.

[0032] Equipment installation: Use a jack or lifting equipment to slowly lower the reactor onto the vibration isolation support. Ensure complete fit between the equipment and the support, avoiding suspension or uneven stress. Align it with the fixing holes on the support and tighten the bolts. Use a level to check if the equipment is level. If it is tilted, the height of the support can be adjusted appropriately. Gently shake the equipment to observe if it is stable and without looseness.

[0033] The specific vibration reduction effect is calculated as follows:

[0034] Equipment mass: M = 17720 kg

[0035] Elastic modulus of polystyrene: E = 3×10 6 Pa

[0036] Bottom area of the support A = 0.2 2 = 0.04 m 2

[0037] Thickness of the support: t = 0.1 m

[0038] Damping ratio is taken as 0.05

[0039] Stiffness calculation:

[0040]

[0041] If 9 supports are used, then

[0042] Natural frequency:

[0043]

[0044] Excitation frequency f work= 100 Hz

[0045] Transmission ratio:

[0046] Transmission rate formula:

[0047]

[0048] Vibration isolation efficiency:

[0049] E = (1 - TR) × 100% = (1 - 0.00424) × 100% = 99.576%

[0050] Through theoretical analysis and calculation, for the floor vibration caused by the reactor, the vibration reduction rate of the polystyrene vibration isolation bearing is as high as 99.576%, showing excellent vibration reduction effect.

[0051] The above are only the embodiments of the present application and are not intended to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application.
