Description

Technical Field

[0001] This invention relates to the field of vibration isolator technology, specifically to a hybrid vibration isolator and method for dual-control vibration control of electrical equipment. Background Technology

[0002] Reactors, transformers, and other electrical equipment are core and critical components of power systems, and their operational stability directly determines the reliability of power supply. Existing vibration isolation devices for electrical equipment mostly employ a single rubber buffer structure for vibration isolation, which can only provide simple buffering for vibrations in a single direction and is difficult to achieve simultaneous multi-directional, all-around vibration control. Single rubber components are prone to excessive deformation and rapid aging due to concentrated loads, easily leading to fatigue failure. Some vibration isolation structures lack a linkage design for their buffer components, making vibration energy prone to local concentration and vibration amplification, resulting in poor vibration isolation stability. Therefore, we introduce a hybrid vibration isolator and method for dual vibration control of electrical equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a hybrid vibration isolator and method for dual vibration control of electrical equipment, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A hybrid vibration isolator for dual-control vibration control of electrical equipment includes a base, a bottom buffer assembly inside the base, and a buffer support assembly sitting on the upper end of the bottom buffer assembly. The bottom buffer assembly is used to achieve vibration isolation and buffering of the buffer support assembly from the vertical direction.

[0006] The buffer support assembly includes a cross seat for mounting an electromagnet and a side buffer connection assembly for connecting the side of the cross seat, wherein the side of the cross seat slides against the inner wall of the base.

[0007] A swing buffer assembly is located on the top of the cross seat. The swing buffer assembly includes a cross swing seat, a rubber support provided at the upper end of the cross swing seat, a ball provided on the lower side of the cross swing seat, and a magnet fixed in the middle of the lower end of the cross swing seat.

[0008] The ball bearing is supported in the arc-shaped groove at the upper end of the cross seat, and the upper end of the rubber support is seated on a mounting base, with the top of the side buffer connection assembly pinned to the lower end of the mounting base.

[0009] Preferably, the upper end of the base is provided with a receiving groove in the center, and the side wall of the receiving groove is provided with a sliding groove;

[0010] The bottom buffer assembly includes a central rubber buffer cylinder fixed in the receiving groove and a side rubber buffer cylinder fixed at the bottom of the slide groove. The bottom of the central rubber buffer cylinder and the bottom of the side rubber buffer cylinder are connected by a pipe. The cross seat is located on the upper end of the central rubber buffer cylinder and the side rubber buffer cylinder.

[0011] Preferably, the interior of the intermediate rubber buffer cylinder is further provided with a metal buffer frame, the upper end of which is supported on the top wall of the intermediate rubber buffer cylinder.

[0012] Preferably, the side end of the cross seat is slidably connected to the corresponding groove, and an end cap is fixed to the upper end of the base, the end cap sealing the top of the groove.

[0013] Preferably, the side buffer connection assembly includes limit seats evenly distributed on the side of the cross seat, diagonal braces penetrating inside the limit seats, an L-shaped frame provided on the side of the limit seats, and a torsion spring bolted to the L-shaped frame.

[0014] The torsion spring is sleeved on the outside of the bolt, one end of the torsion spring is fixed to the inner wall of the L-shaped frame, and the other end of the torsion spring is fixed to an annular seat.

[0015] The bottom of the diagonal brace is connected to the upper end of the annular seat by a connecting pin, and the top of the diagonal brace is connected to the lower end of the mounting seat by a connecting pin.

[0016] Preferably, the limiting seat has a reserved through groove for the protruding diagonal brace to pass through.

[0017] Preferably, the upper center of the cross-shaped base is provided with a mounting groove for mounting an electromagnet, and the magnet block is located directly above the electromagnet.

[0018] The ball bearings are installed using an arc-shaped shell on the lower side of the cross-shaped swing seat;

[0019] The rubber support includes an intermediate rubber seat located at the middle of the upper end of the cross swing seat and a side rubber seat fixed to the side of the upper end of the cross swing seat.

[0020] The present invention also provides a vibration isolation method for a hybrid vibration isolator with dual vibration control for electrical equipment, specifically including the following steps:

[0021] S1. When the electromagnet is energized, the magnetic block forms an attractive force on the swing buffer assembly to buffer the swing of the swing buffer assembly.

[0022] S2. The bottom buffer assembly is used to provide vibration isolation and buffering for the buffer support assembly from the vertical direction.

[0023] S3. The side buffer connection component of the buffer support assembly is used to connect the mounting base, and the side buffer connection component is combined with the rubber support at the upper end of the swing buffer assembly to jointly form a buffer for the mounting base.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the present invention adopts a bottom buffer component, a buffer support component, and a swing buffer component working together, combining mechanical buffering and electromagnetic control to achieve all-round vibration control in the vertical, horizontal, and swing directions, thus solving the defect of single-direction vibration isolation in traditional devices.

[0025] The middle and side rubber buffer cylinders are connected by pipes to form a linkage structure, which evenly distributes the load, disperses vibration energy, avoids local vibration amplification, and works with metal buffer frames to limit excessive deformation of the rubber cylinders, prevent rubber fatigue failure, improve load-bearing capacity, extend the service life of the buffer components, and solve the problems of easy aging and concentrated load of single rubber structures.

[0026] Electromagnets and magnets work together precisely to achieve electromagnetic control, which can dynamically adjust the attraction force to control the swing amplitude. The combination of ball bearings and arc-shaped grooves reduces frictional resistance, improves the control accuracy of small swing amplitudes and buffer response speed, and solves the problems of low control accuracy and slow response of traditional pure mechanical structures.

[0027] The composite structure combining multi-point support, oblique buffer, and vertical support ensures the stability of the mounting base, evenly distributes the load to prevent equipment tilting, and the damping performance of the rubber support effectively absorbs high-frequency vibrations, protecting the precision components inside the electrical equipment.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example:

[0044] Please see Figures 1-13 The present invention provides a technical solution:

[0045] A hybrid vibration isolator for dual-control vibration control of electrical equipment includes a base 1, with a bottom buffer assembly inside the base 1; a receiving groove 101 is centrally located inside the upper end of the base 1, and a sliding groove 102 is provided on the side wall of the receiving groove 101; the bottom buffer assembly includes a central rubber buffer cylinder 103 fixed in the receiving groove 101 and a side rubber buffer cylinder 104 fixed at the bottom of the sliding groove 102, the bottom of the side of the central rubber buffer cylinder 103 and the bottom of the side rubber buffer cylinder 104 are connected by a pipe 105, and a cross seat 201 is located on the upper end of the central rubber buffer cylinder 103 and the side rubber buffer cylinder 104.

[0046] The design of connecting the middle rubber buffer cylinder 103 and the side rubber buffer cylinder 104 through the pipe 105 forms a linkage buffer structure, which can evenly distribute the vertical vibration load, avoid the rapid aging or damage of a single buffer component due to load concentration, and extend the service life of the buffer assembly. At the same time, the connected structure can realize the dispersion and transmission of vibration energy, improve the overall vertical vibration isolation stability, and avoid the occurrence of local vibration amplification.

[0047] The intermediate rubber buffer cylinder 103 also has a metal buffer frame 106 inside, with the upper end of the metal buffer frame 106 supported on the top wall of the intermediate rubber buffer cylinder 103. The metal buffer frame 106 inside the intermediate rubber buffer cylinder 103, with its upper end supported on the top wall, retains the elastic cushioning performance of the rubber material while limiting excessive deformation of the rubber cylinder through the rigid support of the metal frame, preventing long-term pressure fatigue failure of the rubber material. It also enhances the load-bearing capacity of the buffer assembly, making it suitable for electrical equipment of different weights.

[0048] The side rubber buffer cylinder 104 is fixed to the bottom of the slide groove 102. The cross seat 201 is located on the upper end of the middle rubber buffer cylinder 103 and the side rubber buffer cylinder 104, forming a multi-point support structure of "central + side". This structure not only ensures the installation stability of the cross seat 201, but also further weakens vertical vibration through multi-point buffering, while providing a vertical positioning foundation for the cross seat 201. The side end of the cross seat 201 slides into the corresponding slide groove 102, and an end cap 4 is fixed to the upper end of the base 1, sealing the top of the slide groove 102. This connection method not only realizes the sliding fit between the cross seat 201 and the base 1, ensuring the buffer displacement space in the vertical direction, but also restricts the vertical displacement of the cross seat 201 through the end cap 4, preventing it from detaching from the slide groove 102 during vibration, thus improving structural safety. At the same time, the slide groove 102 can guide the vertical displacement of the cross seat 201, preventing it from shifting or twisting, and ensuring the coaxiality of the overall structure.

[0049] A buffer support assembly 2 is located on the upper end of the bottom buffer assembly. The bottom buffer assembly is used to provide vibration isolation and buffering for the buffer support assembly 2 in the vertical direction. The buffer support assembly 2 includes a cross seat 201 for mounting the electromagnet 202 and a side buffer connection assembly connected to the side of the cross seat 201. The side of the cross seat 201 slides against the inner wall of the base 1. The side buffer connection assembly includes limit seats 205 evenly distributed on the side of the cross seat 201, a diagonal brace 206 penetrating inside the limit seat 205, an L-shaped frame 208 set on the side of the limit seat 205, and a torsion spring 209 set on the L-shaped frame 208 by bolts 211. The torsion spring 209 is sleeved on the outside of the bolts 211, and one end of the torsion spring 209 is fixed to the inner wall of the L-shaped frame 208. The other end of the torsion spring 209 is fixed with an annular seat 207; the side buffer connection assembly adopts a combination structure of "limit seat 205 + diagonal brace 206 + torsion spring 209". The limit seats 205 are evenly distributed on the side of the cross seat 201, which can realize multi-point diagonal support for the mounting seat 5 and improve the stability of the mounting seat 5; the diagonal brace 206 is connected to the torsion spring 209 through the annular seat 207. The torsion spring 209 is sleeved on the outside of the bolt 211 and its two ends are fixed to the L-shaped frame 208 and the annular seat 207 respectively. This drive structure can convert the linear displacement of the diagonal brace 206 into the torsional deformation of the torsion spring 209. Automatic buffering and reset are achieved through the elastic restoring force of the torsion spring 209. No additional power drive is required. The structure is simple and the buffering response is fast.

[0050] The limiting seat 205 has a reserved through slot 210 for the protruding diagonal brace 206 to pass through. The reserved through slot 210 provides sufficient space for the rotation and displacement of the diagonal brace 206, avoiding mechanical interference between the diagonal brace 206 and the limiting seat 205, and ensuring the smoothness of the buffering process; at the same time, the reserved through slot 210 can limit the range of motion of the diagonal brace 206, preventing excessive rotation that could cause structural damage, and achieving limiting protection for the side buffer connection components.

[0051] The bottom of the diagonal brace 206 is connected to the upper end of the ring seat 207 by a connecting pin, and the top of the diagonal brace 206 is connected to the lower end of the mounting base 5 by a connecting pin. The top of the side buffer connecting assembly is pinned to the lower end of the mounting base 5, and together with the rubber support of the swing buffer assembly 3, it supports the mounting base 5, forming a composite support structure of "diagonal buffer + vertical support". This structure can resist horizontal and diagonal vibrations and stably bear the weight of the equipment, achieving all-round vibration control. Each component adopts a modular design. For example, the bottom buffer assembly, buffer support assembly 2, and swing buffer assembly 3 can be independently disassembled and installed, which is convenient for maintenance and replacement. At the same time, the component parameters can be adjusted according to different vibration scenarios (such as changing the hardness of the rubber material and adjusting the electromagnet current) to improve the adaptability of the equipment.

[0052] A swing buffer assembly 3 is mounted on the top of the cross seat 201. The swing buffer assembly 3 includes a cross swing seat 301, a rubber support at the upper end of the cross swing seat 301, a ball bearing 305 on the lower side of the cross swing seat 301, and a magnet block 306 fixed in the middle of the lower end of the cross swing seat 301. The upper middle of the cross seat 201 has a mounting groove 203 for mounting an electromagnet 202, and the magnet block 306 is located directly above the electromagnet 202. The mounting groove 203 in the upper middle of the cross seat 201 is used to mount the electromagnet 202, so that the electromagnet 202 and the magnet block 306 of the swing buffer assembly 3 are precisely aligned (the magnet block 306 is located directly above the electromagnet 202), ensuring the stable transmission of electromagnetic attraction, thereby precisely controlling the swing amplitude of the cross swing seat 301, realizing a dual control mode of "mechanical buffer + electromagnetic control", and improving the control accuracy of small swings.

[0053] The magnet block 306 is fixed at the lower middle part of the cross swing seat 301, forming an upper and lower corresponding structure with the electromagnet 202. This arrangement allows the electromagnetic attraction force to act on the middle part of the cross swing seat 301 in the vertical direction, avoiding the generation of eccentric torque, ensuring the force balance of the cross swing seat 301, thereby achieving precise control of the swing amplitude. At the same time, it can assist the cross swing seat 301 to reset and improve the stability of the vibration isolation system.

[0054] The ball bearing 305 is mounted on the arc-shaped shell 304 on the lower side of the cross swing seat 301. The ball bearing 305 is supported in the arc-shaped groove 204 of the cross seat 201. This connection method converts the sliding friction between the cross swing seat 301 and the cross seat 201 into rolling friction, which greatly reduces the frictional resistance during the swing process, enabling the cross swing seat 301 to quickly adapt to small vibrations and improve the buffer response speed. At the same time, the curved surface design of the arc-shaped groove 204 can guide the ball bearing 305, limit the swing range, and prevent the cross swing seat 301 from shifting significantly.

[0055] The rubber support includes an intermediate rubber seat 302 located at the middle of the upper end of the cross swing seat 301 and a side rubber seat 303 fixed to the side of the upper end of the cross swing seat 301.

[0056] The rubber support adopts a combination structure of "middle rubber seat 302 + side rubber seat 303". The middle rubber seat 302 corresponds to the middle of the mounting base 5, and the side rubber seat 303 corresponds to the side of the mounting base 5, forming a multi-point elastic support. This can evenly distribute the weight and vibration load of the mounting base 5 and prevent the mounting base 5 from tilting due to uneven force. At the same time, the rubber material has good damping performance, which can effectively absorb high-frequency vibration, reduce the impact of vibration on electrical equipment, and protect the precision components inside the equipment.

[0057] The ball bearing 305 is supported in the arc-shaped groove 204 at the upper end of the cross seat 201. The upper end of the rubber support is seated on the mounting base 5, and the top of the side buffer connection assembly is pinned to the lower end of the mounting base 5. Electrical equipment (reactor, etc.) is installed on the upper end of the mounting base 5.

[0058] The present invention also provides a vibration isolation method for a hybrid vibration isolator with dual vibration control for electrical equipment, specifically including the following steps:

[0059] S1. When the electromagnet 202 is energized, the magnet block 306 forms an attractive force on the swing buffer assembly 3 to buffer the swing of the swing buffer assembly 3.

[0060] S2, The bottom buffer assembly is used to achieve vibration isolation and buffering of the buffer support assembly 2 from the vertical direction;

[0061] S3, the side buffer connection component of the buffer support component 2 is used to connect the mounting base 5, and the side buffer connection component is combined with the rubber support at the upper end of the swing buffer component 3 to jointly form a buffer for the mounting base 5.

[0062] Specifically, when using it:

[0063] This hybrid vibration isolator achieves dual-control vibration isolation of electrical equipment through the synergistic effect of the bottom buffer component, buffer support component 2, and swing buffer component 3, combined with electromagnetic control and mechanical buffer structure. The specific working process and the function of each component are as follows:

[0064] (I) Overall vibration isolation logic:

[0065] The electrical equipment is installed on the upper end of the mounting base 5. When external vibration occurs, the vibration is first transmitted to the base 1. The base 1 achieves initial vertical vibration isolation through its internal bottom buffer component.

[0066] The remaining vibration is then transmitted to the buffer support assembly 2. The buffer support assembly 2 restricts horizontal displacement on the one hand by sliding the cross seat 201 with the inner wall of the base 1, and on the other hand by forming an oblique buffer for the mounting base 5 through the side buffer connection assembly.

[0067] Meanwhile, the swing buffer assembly 3 adapts to the swing caused by small vibrations through the cooperation of the ball bearing 305 and the arc groove 204. Combined with the electromagnetic attraction of the electromagnet 202 and the magnet block 306, the swing amplitude is controlled. Finally, the vibration is buffered at the end through the rubber support, thus completing the all-round vibration control of "vertical vibration isolation + horizontal buffering + swing control".

[0068] (II) Working process of each component:

[0069] Vertical vibration isolation process of bottom buffer assembly: When vibration is transmitted from base 1 to receiving groove 101, the middle rubber buffer cylinder 103 first absorbs the vertical vibration energy through its own elastic deformation. The internal metal buffer frame 106 further enhances the structural rigidity, avoids excessive deformation of the middle rubber buffer cylinder 103, and disperses the vibration pressure through the support of the upper end of the metal buffer frame 106 on the top wall of the middle rubber buffer cylinder 103.

[0070] Since the middle rubber buffer cylinder 103 and the side rubber buffer cylinder 104 are connected by the pipe 105, the internal air pressure or hydraulic pressure of the two can be adjusted to achieve balanced transmission and absorption of vibration energy, avoid local stress concentration, and thus form a stable vertical vibration isolation support for the cross seat 201 located above, weakening the impact of vertical vibration on the buffer support component 2.

[0071] Vertical and oblique buffering process of buffer support component 2: The side end of cross seat 201 slides into the groove 102 of base 1. When vertical vibration occurs, the groove 102 limits the vertical displacement range of cross seat 201 to prevent it from shifting significantly.

[0072] Meanwhile, the diagonal brace 206 in the side buffer connection assembly is connected to the ring seat 207 and the mounting seat 5 respectively through the connecting pins at both ends. When the mounting seat 5 is displaced, the diagonal brace 206 rotates around the connecting pin, causing the ring seat 207 to compress the torsion spring 209. The torsion spring 209 absorbs the vertical and diagonal vibration energy through its own elastic deformation, and then transmits it to the cross seat 201 through the L-shaped frame 208, so as to realize the diagonal buffering and reset of the mounting seat 5.

[0073] The reserved through groove 210 inside the limit seat 205 provides space for the rotation of the diagonal brace 206, avoiding interference between the diagonal brace 206 and the limit seat 205 when the diagonal brace 206 moves, and ensuring the smoothness of the buffering process.

[0074] The swing control and terminal buffering process of the swing buffer assembly 3: When the equipment swings slightly, the cross swing seat 301 rolls in the arc groove 204 at the upper end of the cross seat 201 through the ball bearing 305 on the lower side to adapt to the swing posture and reduce the frictional resistance during the swing process.

[0075] Meanwhile, when the electromagnet 202 is energized, it generates a magnetic field that attracts the magnet block 306 located directly above it. This attraction can be dynamically adjusted according to the vibration amplitude (by changing the magnitude of the current to control the magnetic field strength), thereby limiting the swing amplitude of the cross swing seat 301 and preventing large swings from damaging the equipment.

[0076] The middle rubber seat 302 and the side rubber seat 303 at the upper end of the cross swing seat 301 directly support the mounting base 5. The remaining vibration energy is absorbed by the elastic deformation of the rubber material, so as to realize terminal vibration isolation and ensure the stability of the electrical equipment on the mounting base 5.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
