Description

Technical Field

[0001] This invention relates to the field of seismic bracing technology, and more particularly to a seismic bracing for cable trays. Background Technology

[0002] Seismic bracing for wind turbines is a special support structure designed specifically for wind turbine equipment in building electromechanical systems, possessing seismic protection functions. Its function is to effectively resist the effects of earthquakes and vibrations generated by the operation of the wind turbine itself, while meeting the daily operating load requirements of the wind turbine, through scientific mechanical structural design. In the event of an earthquake, it can absorb and disperse earthquake energy, preventing the wind turbine from shifting, tilting, or even falling due to violent shaking, and preventing damage to the wind turbine or related damage to key devices such as building ventilation and fire smoke exhaust.

[0003] Traditional wind turbine support systems are primarily designed to meet the static load-bearing requirements of the wind turbine under normal operating conditions. However, in practical applications, the high-speed operation of the motor during wind turbine operation generates continuous vibrations. These vibrations are transmitted through the wind turbine base to the entire support system. Traditional supports lack effective vibration damping structures, and prolonged vibrations can lead to the gradual loosening of bolts connecting the support to the building structure, fatigue cracking of welds, and further transmission of vibrations to the building structure or surrounding pipelines, causing resonance noise pollution. Simultaneously, it accelerates the wear of internal wind turbine components, shortening the equipment's lifespan. Therefore, a seismic-resistant cable tray support system is needed to address these issues.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention provides a seismic-resistant cable tray support to address the problems of traditional wind turbine supports that focus on static load bearing, lack shock-absorbing structures, and cause bolt loosening, noise, and shortened wind turbine lifespan due to wind turbine vibration.

[0006] The present invention adopts the following technical solution: a seismic bracing for cable trays. The system includes a support assembly comprising a horizontally arranged channel steel base with two symmetrically arranged fixing parts, each including a fully threaded hanger connected to the channel steel base. Three sets of anti-vibration parts are shared on the two sets of fully threaded hangers. A connecting part is provided on the channel steel base. Two sets of vibration damping components are disposed between the channel steel base and the connecting parts, used to disperse the vibration force of the fan. Two sets of damping maintenance components are disposed on the side of the channel steel base, each including an oil reservoir for providing high-viscosity damping oil. The oil reservoir includes a right-angle frame fixed to the side of the channel steel base, with a pressing part at the vertical end of the right-angle frame providing power for drawing high-viscosity damping oil. A suction part is provided on the oil reservoir to draw out the high-viscosity damping oil, and a collection part is provided on the side of the vertical end of the right-angle frame to collect excess high-viscosity damping oil.

[0007] Furthermore, the damping assembly includes a lower connecting seat fixed to the channel steel base by high-strength bolts. The top of the lower connecting seat is open, and an upper connecting seat is disposed inside the opening of the lower connecting seat. The bottom of the upper connecting seat has a protrusion, a portion of which extends into the opening and contacts the inner wall of the opening of the lower connecting seat. Both the protrusion and the inner wall of the opening of the lower connecting seat have damping mating surfaces at their contact points. A damping spring is disposed between the lower connecting seat and the upper connecting seat, and four sets of damping springs are equidistantly arranged along the circumference of the lower connecting seat.

[0008] Furthermore, four sets of guide rods are equidistantly and regularly arranged along the axial direction on the lower connecting seat. One end of each guide rod movably passes through the upper connecting seat. The upper connecting seat has a through hole larger than the diameter of the guide rod. One end of each guide rod has an anti-detachment end. A pre-tightening spring is sleeved on the guide rod. The two ends of the pre-tightening spring are respectively connected to the bottom of the anti-detachment end and the upper end face of the upper connecting seat. A connecting piece is fixed to the bottom surface of the mounting seat of the connecting part by bolts.

[0009] Furthermore, the right-angle frame has a fixing ring on its side, and a high-viscosity damping oil bottle is attached to the fixing ring. The high-viscosity damping oil bottle stores high-viscosity damping oil. A viewing window is provided at the bottom of the inner wall of the high-viscosity damping oil bottle. A screw cap is threaded to the top of the high-viscosity damping oil bottle. An oil outlet pipe is connected to the bottom of the high-viscosity damping oil bottle. A one-way valve is connected between one end of the oil outlet pipe and the high-viscosity damping oil bottle.

[0010] Furthermore, the pressing part includes a concave frame fixedly mounted on the top of the vertical end of the right-angle frame. A curved arm is movably mounted on the concave frame via a connecting shaft. One end of the curved arm is integrally provided with a pressing end. A support member is fixedly sleeved on the vertical end of the right-angle frame. Two sets of return springs connected to the pressing end are fixed on the support member. A connecting end extends outward from the side of the upper connecting seat. The surface of the connecting end has a contact ball rod. The contact ball rod is in contact with the bottom surface of the pressing end in the default state.

[0011] Furthermore, the suction unit includes a support column fixed on the fixed ring, and a vertically arranged cylinder is fixed to the side of the support column by a collar. One end of the oil outlet pipe is connected to the bottom of the cylinder for introducing high-viscosity damping oil into the cylinder. A piston rod is movably arranged inside the cylinder, and one end of the piston rod is movably connected to one end of the crank arm. Two-thirds of the position of the crank arm is movably connected to the concave frame to form a force-saving lever structure.

[0012] Furthermore, the side of the cylinder is connected to an oil drain pipe for discharging high-viscosity damping oil from the cylinder. A support seat one for supporting the oil drain pipe is fixed on the side of the mounting base. One end of the oil drain pipe is connected to an oil nozzle. A support seat two for supporting the oil nozzle is fixed on the side of the mounting base. The bottom end of the oil nozzle has a rigid oil pipe. One end of the rigid oil pipe movably passes through the upper connecting seat. The upper connecting seat has a through hole larger than the diameter of the rigid oil pipe.

[0013] Furthermore, an annular oil storage tank is fitted onto the protrusion of the upper connecting seat. The oil storage tank has a sloped oil drain groove inside, which is annular. One end of the rigid oil pipe passes through the upper connecting seat and is connected to the oil storage tank. The bottom surface of the oil storage tank has multiple sets of inclined drain holes along its circumference. The inclined drain holes are set towards the surface of the protrusion. The high-viscosity damping oil initially discharged through the rigid oil pipe falls at the high point of the oil drain groove.

[0014] Furthermore, the collection unit includes an oil collecting bottle fixed to the side of the vertical end of the right-angle frame. The bottom of the oil collecting bottle is connected to the top of a high-viscosity damping oil bottle via a hose. A filter screen is installed inside the oil collecting bottle. An inclined oil collecting pipe is connected to the side of the oil collecting bottle. One end of the oil collecting pipe is connected to the side of the lower connecting seat.

[0015] Furthermore, channel steel end caps are fixed at both ends of the channel steel base, the fully threaded rod is set in a vertical position, an external coiled gasket is provided at one end of the fully threaded rod, the external coiled gasket is tightly and evenly attached to the bottom of the channel steel base, a C-shaped channel steel II is fixed to the fully threaded rod by bolts, and a hexagonal connector is provided at one end of the fully threaded rod;

[0016] The three sets of seismic-resistant components are defined from left to right as Seismic-resistant Component 1, Seismic-resistant Component 2, and Seismic-resistant Component 3. Seismic-resistant Component 1 and Seismic-resistant Component 2 are mounted on a set of fully threaded rods near the left side, and Seismic-resistant Component 3 is mounted on a set of fully threaded rods near the right side. Each seismic-resistant component includes a seismic-resistant hinge fixed to the fully threaded rod. One end of the seismic-resistant hinge has a connecting piece, and a C-shaped channel steel is fixed on the connecting piece. The C-shaped channel steel is spaced apart from the C-shaped channel steel. One end of the C-shaped channel steel is fixed with a rear-expanded bottom anchor bolt. The seismic-resistant components 1 and 2 are spaced horizontally. A V-shaped stiffener is provided on the side of the C-shaped channel steel. The connecting part includes two sets of symmetrical cable tray limiters adapted to the fan installation dimensions. A mounting base is fixed between the two sets of cable tray limiters.

[0017] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0018] A seismic bracing system for cable trays integrates support components, vibration damping components, and damping maintenance components on a horizontally positioned channel steel base. The channel steel base, combined with a fixing unit featuring fully threaded hangers and three sets of seismic-resistant components, effectively suppresses continuous vibrations generated by the high-speed operation of the wind turbine while meeting the static load-bearing requirements of the wind turbine. This prevents the direct transmission of vibration energy to the main building structure, thus avoiding bolt loosening and weld fatigue cracking. Secondly, two sets of vibration damping components, positioned between the channel steel base and the connecting parts, capture and disperse subtle high-frequency vibrations transmitted from the wind turbine base. This active buffering mechanism reduces resonance noise pollution and effectively alleviates vibration wear on internal wind turbine components. Finally, the two sets of damping maintenance components, through the coordinated operation of an oil storage section, a pressing section, a suction section, and a collection section, utilize wind turbine vibration as a driving force to automatically replenish and circulate high-viscosity damping oil. This ensures the vibration damping system remains in optimal damping condition, solving the problem of vibration damping performance degradation caused by lack of maintenance in traditional structures, thereby extending the overall service life of the wind turbine and support system.

[0034] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0035] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Reference Figures 1-3 As shown, this embodiment of the invention provides a seismic-resistant cable tray support, which can provide stable and vibration-resistant support for fan equipment in the seismic protection of actual building ventilation systems. The support assembly 1 includes a horizontally arranged channel steel base 11, on which fan equipment can be installed. Channel steel end caps 13 are fixed to both ends of the channel steel base 11 by welding, preventing dust and impurities from entering the channel steel base 11 and enhancing the structural strength of the ends of the channel steel base 11 to avoid deformation under stress. Furthermore, the channel steel base 11 is provided with… Two sets of symmetrically arranged fixing parts are provided. Each fixing part includes a fully threaded hanger 17 that is threaded through and connected to the channel steel base 11. During actual installation, professional tools are required to tighten the fully threaded hanger 17 to the channel steel base 11 to ensure the stability of the connection. The fully threaded hanger 17 is set in a vertical position, and one end of the fully threaded hanger 17 is provided with an external coiled gasket 12. The external coiled gasket 12 is tightly and evenly attached to the bottom of the channel steel base 11, which can distribute the pressure of the fully threaded hanger 17 on the channel steel base 11 and prevent the channel steel base 11 from being damaged locally due to excessive pressure.

[0038] Furthermore, a C-shaped channel steel 16 is bolted to the threaded rod 17, and a connector 111 is provided at one end of the threaded rod 17. This connector 111 is specifically and appropriately adapted for connection to the top of the wall. In actual construction, it needs to be used with expansion bolts and other fasteners to firmly fix the connector 111 to the top of the wall. At the same time, in order to further improve the seismic resistance of the support, three sets of seismic-resistant parts are provided on both sets of threaded rods 17, and at this point... Figure 2 Based on this, the three sets of seismic-resistant components are defined from left to right as Seismic-resistant Component 1, Seismic-resistant Component 2, and Seismic-resistant Component 3. Seismic-resistant Component 1 and Seismic-resistant Component 2 are mounted on a set of fully threaded hangers 17 located near the left side, while Seismic-resistant Component 3 is mounted on a set of fully threaded hangers 17 located near the right side (see reference). Figure 2 In actual building electromechanical seismic engineering, this layout can more comprehensively disperse seismic forces. The symmetrical arrangement of seismic-resistant section two and seismic-resistant section three can make the force on the left and right sides of the support more balanced.

[0039] The seismic-resistant component includes a seismic-resistant hinge 14 that is bolted and threaded onto a fully threaded hanger 17. During actual installation, the tightness of the threaded connection must be ensured to guarantee seismic performance. One end of the seismic-resistant hinge 14 has a connecting piece 141, and a C-shaped channel steel 15 is bolted to the connecting piece 141. The C-shaped channel steel 15 and the C-shaped channel steel 16 are spaced 45 degrees apart, i.e., installed at a 45-degree angle to the vertical. This angle design can more efficiently transmit and disperse seismic forces. A rear-expanded bottom anchor bolt 112 is fixed to one end of the C-shaped channel steel 15. The rear-expanded bottom anchor bolt 112 has advantages such as strong anchoring force and applicability to concrete structures in actual engineering, and can provide a reliable fixed foundation for the seismic-resistant component. It should be noted that the seismic-resistant component 1 and the seismic-resistant component 2 are spaced 90 degrees apart horizontally. This 90-degree interval layout can provide seismic reinforcement to the support from different directions, further enhancing the overall seismic stability of the support.

[0040] Furthermore, a V-shaped stiffener 19 is provided on the side of the C-shaped channel steel 16. In actual building electromechanical engineering, the V-shaped stiffener 19 can effectively enhance the structural strength and deformation resistance of the C-shaped channel steel 16, improve the overall stability of the support, and a connecting part is provided on the channel steel base 11. This connecting part includes two sets of symmetrical cable tray limiters 18 that are fixed to the channel steel base 11 by high-strength bolts and adapted to the installation size of the fan. The bolt connection method makes it easy to adjust the position of the cable tray limiters 18 according to the actual fan specifications. A mounting base 110 is fixed between the two sets of cable tray limiters 18 by bolts. In actual use, the fan can be installed on the mounting base 110. This design can play a good role in limiting and supporting the fan, ensuring that the fan remains stable under operating conditions and earthquakes, and avoiding displacement or shaking.

[0041] Working Principle: When a building experiences external vibrations such as earthquakes, the vibrations generated by the fan equipment and the forces transmitted by seismic waves first act on the mounting base 110. The mounting base 110 is fixed to two sets of cable tray limiters 18 by bolts. The cable tray limiters 18 are in turn connected to the channel steel base 11 by high-strength bolts, thus transmitting the vibration force to the channel steel base 11. The channel steel end caps 13 at both ends of the channel steel base 11 enhance the end structural strength and can initially resist some of the deformation tendencies caused by vibration. At the same time, the external rolled gaskets 12 at the bottom of the channel steel base 11 can disperse the pressure transmitted by the fully threaded hanger 17, preventing local damage to the channel steel base 11 due to stress concentration, allowing the channel steel base 11 to bear the vibration force relatively stably.

[0042] Next, the vibration force is transmitted upwards and downwards through the fully threaded hanger 17. When transmitted upwards, the connector 111 at one end of the fully threaded hanger 17 is firmly connected to the top of the wall using expansion bolts and other fasteners. The robust structure of the top of the wall effectively absorbs and disperses this portion of the vibration force. When transmitted downwards, the seismic-resistant components on the fully threaded hanger 17 begin to function. The seismic-resistant hinge 14 is firmly connected to the fully threaded hanger 17 via high-strength threads. Its connecting piece 141 at one end is fixed to the C-shaped channel steel 15 with bolts. The C-shaped channel steel 15 and the C-shaped channel steel 16 are spaced at 45-degree intervals. This angled arrangement efficiently transmits the vibration force to the side, and then through the rear-expanded bottom anchor bolt 112 at one end of the C-shaped channel steel 15 to the top of the wall. The rear-expanded bottom anchor bolt 112 has strong anchoring force, which further disperses the vibration force. Meanwhile, the layout of the three sets of seismic-resistant sections (Seismic-resistant section 1, Seismic-resistant section 2, and Seismic-resistant section 3), especially the symmetrical arrangement of Seismic-resistant section 2 and Seismic-resistant section 3 and the 90-degree interval between Seismic-resistant section 1 and Seismic-resistant section 2, can disperse the vibration force from different directions, avoid excessive stress on one side of the support, and enhance the overall seismic stability.

[0043] In addition, the V-shaped stiffeners 19 on the side of the C-shaped channel steel 216 enhance its structural strength and deformation resistance, making it less prone to deformation during the transmission of vibration forces, thus further ensuring the overall stability of the support. Through this force transmission and dispersion process, the entire cable tray seismic support can effectively resist the impact of earthquakes and other vibrations, providing stable and vibration-resistant support for the wind turbine equipment, ensuring the stability of the wind turbine during operation and under seismic conditions, and preventing displacement or swaying.

[0044] Example 2:

[0045] To further overcome the shortcomings of traditional wind turbine supports, such as bolt loosening, noise pollution, and shortened structural fatigue life caused by the direct transmission of vibration energy due to the lack of efficient vibration damping mechanisms, this embodiment introduces an active viscous damping circulation structure. This aims to achieve efficient conversion of vibration energy and long-term maintenance of vibration damping performance. Figures 4-6As shown, unlike the above embodiment, two sets of damping components 2 are provided between the channel steel base 11 and the connecting part. The two sets of damping components 2 are symmetrically arranged. In the actual installation and operation of the wind turbine, the symmetrical damping components 2 can more evenly disperse the force brought by the wind turbine vibration. The damping component 2 includes a lower connecting seat 21 fixed to the channel steel base 11 by high-strength bolts 22. The cross-section of the lower connecting seat 21 is an inverted T-shaped design. The top of the lower connecting seat 21 has a downward-facing inner groove (not shown in the figure). An upper connecting seat 23 is fitted in the inner groove of the lower connecting seat 21 with a gap. The bottom of the upper connecting seat 23 has a protrusion 231. The protrusion 231 extends into the inner groove in a partial position. The protrusion 231 contacts the inner wall of the lower connecting seat 21. An annular protective cover 232 is fixed on the bottom surface of the lower connecting seat 21. The protective cover 232 fits onto the lower connecting seat 21.

[0046] Specifically, a limiting damping cavity is formed between the protrusion 231 and the lower connecting seat 21, and the high-viscosity damping oil filled in the cavity forms a high-strength shear fluid film within the micro-gap. This creates a solid-liquid hybrid damping interface between the protrusion 231 and the lower connecting seat 21. When vibration occurs, this device utilizes the fluid shear resistance of the high-viscosity medium within the narrow gap to convert mechanical energy into fluid heat energy. This design not only provides flexible guidance for the upper connecting seat 23 but also effectively eliminates collision noise generated by rigid impacts.

[0047] Furthermore, a damping spring 24 is provided between the lower connecting seat 21 and the upper connecting seat 23. Four sets of damping springs 24 are equidistantly arranged along the circumference of the lower connecting seat 21 to provide initial support for the upper connecting seat 23. When vibration occurs during actual fan operation, the four sets of damping springs 24 can function synchronously to effectively buffer the vibration impact. Additionally, four sets of guide rods 25 are equidistantly and regularly arranged along the axial direction of the lower connecting seat 21. One end of each guide rod 25 movably passes through the upper connecting seat 23. Simultaneously, on the upper connecting seat... The guide rod 23 has a through hole (not shown in the figure) larger than the diameter of the guide rod 25, and one end of the guide rod 25 has an anti-detachment end, which can prevent the upper connecting seat 23 from detaching from the guide rod 25 during vibration buffering, thus ensuring the integrity of the shock absorption structure. A pre-tension spring 26 is also sleeved on the guide rod 25. The two ends of the pre-tension spring 26 are connected to the bottom of the anti-detachment end and the upper end face of the upper connecting seat 23, respectively. The pre-tension spring 26 can further enhance the shock absorption effect and play an auxiliary and limiting role in the buffering of the damping spring 24.

[0048] Meanwhile, a connecting piece 27 is fixed on the upper connecting seat 23 and reliably fixed to the bottom surface of the mounting seat 110 of the connecting part by bolt 28. In actual installation, the connecting piece 27 and the mounting seat 110 can be easily fixed by bolt 28 to ensure the stability of the fan installation. When the fan vibrates during operation, the entire shock absorption assembly 2 can effectively absorb vibration energy through the damping spring 24, preload spring 26 and other structures, reduce vibration transmission, prevent bolt loosening, reduce noise, and extend the service life of the fan.

[0049] When the fan vibrates during operation, the vibration force is transmitted to the connector 27 through the mounting base 110, which in turn drives the upper connecting base 23 to move. At this time, the protrusion 231 at the bottom of the upper connecting base 23 contacts the inner wall of the opening of the lower connecting base 21. Since there are damping mating surfaces at the contact points, sliding friction is generated during relative movement, converting the mechanical energy of the vibration into heat energy, consuming the vibration energy, and achieving vibration attenuation. At the same time, the four sets of damping springs 24 between the lower connecting base 21 and the upper connecting base 23 are compressed. The damping springs 24 are evenly distributed around the lower connecting base 21, and can synchronously and evenly bear the pressure, using their own elastic deformation to further absorb the vibration energy and initially buffer the vibration impact. During this process, the guide rod 25 provides guidance for the up and down movement of the upper connecting base 23 to prevent it from deviating. The anti-detachment end of the guide rod 25 prevents the upper connecting base 23 from separating from the guide rod 25, ensuring the integrity of the damping structure.

[0050] While the damping spring 24 is compressed, the preload spring 26 sleeved on the guide rod 25 is also compressed. The two ends of the preload spring 26 are connected to the bottom of the anti-detachment end and the upper end face of the upper connecting seat 23, respectively. The reverse elastic force generated during compression assists the damping spring 24 in buffering the vibration impact, further enhancing the damping effect. When the vibration impact weakens or disappears, the damping spring 24 and the preload spring 26 gradually recover their deformation, pushing the upper connecting seat 23 back to its initial position. The guide rod 25 continues to guide, ensuring the upper connecting seat 23 returns to its stable position. Through the energy dissipation of the damping mating surface and the elastic buffering of the damping spring 24 and the preload spring 26, the entire damping assembly 2 effectively absorbs the vibration energy generated by the fan operation, reducing the transmission of vibration to the channel steel base 11 and other components, thereby preventing bolts from loosening due to vibration, reducing operating noise, and extending the service life of the fan.

[0051] To further address the issue that relying solely on dry friction to dissipate vibration energy between the protrusion 231 and the lower connecting seat 21 would lead to wear of the damping mating surfaces over time, resulting in increased clearance, vibration damping failure, and high-frequency impact noise, such as... Figures 7-9As shown, two sets of damping maintenance components 3 are provided on the side of the channel steel base 11. The damping maintenance components 3 act on the two sets of shock absorbers 2 respectively. In the actual seismic protection scenario of wind turbine operation, the high viscosity damping oil of the shock absorbers 2 on both sides can be replenished and circulated simultaneously. The damping maintenance component 3 includes an oil storage part provided on the side of the channel steel base 11. The oil storage part includes a right-angle frame 31 fixed on the side of the channel steel base 11. The right-angle frame 31 has a fixing ring (not shown in the figure) on its side. A high viscosity damping oil bottle 39 is connected to the fixing ring. The high viscosity damping oil bottle 39 stores high viscosity damping oil. A viewing window is provided at the bottom of the inner wall of the high viscosity damping oil bottle 39. In actual use, the staff can directly see the remaining amount of high viscosity damping oil in the high viscosity damping oil bottle 39 through the viewing window, which is convenient for timely replenishment.

[0052] Furthermore, a screw cap 391 is threaded onto the top of the high-viscosity damping oil bottle 39. During actual maintenance, the operator can easily unscrew the screw cap 391 to replenish the high-viscosity damping oil bottle 39, making the operation convenient. At the same time, an oil outlet pipe 310 is connected to the bottom of the high-viscosity damping oil bottle 39 for conveying high-viscosity damping oil. One end of the oil outlet pipe 310 is connected to the high-viscosity damping oil bottle 39 with a one-way valve, which ensures that the high-viscosity damping oil in the lubricating fluid bottle 39 can only be discharged through the oil outlet pipe 310, preventing the high-viscosity damping oil from flowing back and ensuring the one-way delivery of the high-viscosity damping oil.

[0053] Meanwhile, a pressing part is provided at the vertical end of the right-angle frame 31, which is the power triggering structure for the suction of high-viscosity damping oil. The pressing part includes a concave frame 32 fixedly installed at the top of the vertical end of the right-angle frame 31. A crank arm 33 is movably installed on the concave frame 32 through a connecting shaft and can rotate around the connecting shaft. A pressing end 34 is integrally provided at one end of the crank arm 33. At the same time, a support member 35 is fixedly sleeved on the vertical end of the right-angle frame 31. Two sets of return springs 36 connected to the pressing end 34 are fixed on the support member 35. They can drive the crank arm 33 to return to its original position after the pressing end 34 is subjected to force. Meanwhile, a connecting end 37 extends outward from the side of the upper connecting seat 23. The surface of the connecting end 37 has a contact ball rod 38. In practice, the contact ball rod 38 can reduce friction with the pressing end 34 by rolling. The contact ball rod 38 is in default contact with the bottom surface of the pressing end 34, providing the initial contact condition for triggering the pressing part.

[0054] A suction section is provided on the fixed ring. The suction section includes a support column 311 fixed on the fixed ring. A vertically arranged cylinder 312 is fixed to the side of the support column 311 by a collar. The cylinder 312 is used as a space for temporary storage of high viscosity damping oil. One end of the oil outlet pipe 310 is connected to the bottom of the cylinder 312 to introduce high viscosity damping oil into the cylinder 312. At the same time, a piston rod 313 is movably arranged inside the cylinder 312. Suction is achieved by the reciprocating motion of the piston rod 313. One end of the piston rod 313 is movably connected to one end of the crank arm 33. It should be noted that two-thirds of the position of the crank arm 33 is movably connected to the concave frame 32 to form a force-saving lever structure, which facilitates triggering the suction action.

[0055] Furthermore, an oil drain pipe 314 is connected to the side of the cylinder 312 to drain high-viscosity damping oil from the cylinder 312. At the same time, a support seat 315 supporting the oil drain pipe 314 is fixed to the side of the mounting base 110 by fasteners. One end of the oil drain pipe 314 is connected to an oil nozzle 317. At the same time, a support seat 316 supporting the oil nozzle 317 is fixed to the side of the mounting base 110 by fasteners. The bottom end of the oil nozzle 317 has a rigid oil pipe (not shown in the figure). The rigid oil pipe is used to provide a stable channel for the delivery of high-viscosity damping oil. One end of the rigid oil pipe is movably connected through the upper connecting seat 23. At the same time, a through hole larger than the diameter of the rigid oil pipe is opened on the upper connecting seat 23 to facilitate the movement of the rigid oil pipe with the upper connecting seat 23.

[0056] Furthermore, an annular oil reservoir 320 is fitted onto the protrusion 231 of the upper connecting seat 23, which can temporarily store high-viscosity damping oil and achieve uniform distribution. The interior of the oil reservoir 320 has an oil drain channel (not shown in the figure) with a reasonable slope. This drain channel is annular, with one end of a rigid oil pipe passing through the upper connecting seat 23 and connecting to the oil reservoir 320, facilitating the entry of high-viscosity damping oil into the oil reservoir 320. Simultaneously, multiple sets of cleverly designed inclined drainage holes 321 are formed along the circumference of the bottom surface of the oil reservoir 320. In practice… High-viscosity damping oil can be evenly sprayed out through these drain holes 321. The inclined drain holes 321 are set towards the surface of the protrusion 231. The high-viscosity damping oil initially discharged through the rigid oil pipe falls at the high point of the oil drain groove. Under the action of the slope of the oil drain groove, it can be evenly sprayed through the drain holes 321 onto the surface of the protrusion 231, ensuring that the contact surface between the protrusion 231 and the lower connecting seat 21 is always in a viscous wetted state. While maintaining high-efficiency energy dissipation, it prevents rigid wear and noise caused by physical dry friction.

[0057] Meanwhile, a collection section is provided on the side of the vertical end of the right-angle frame 31. This collection section is used to collect excess high-viscosity damping oil between the protrusion 231 and the opening of the lower connecting seat 21, avoiding waste and pollution. The collection section includes an oil collection bottle 318 fixed to the side of the vertical end of the right-angle frame 31 by fasteners, which can store the recycled high-viscosity damping oil. The bottom of the oil collection bottle 318 is connected to the top of the high-viscosity damping oil bottle 39 through a hose, which facilitates the return of the recycled high-viscosity damping oil to the high-viscosity damping oil bottle for recycling. A filter screen (not shown in the figure) is provided in the oil collection bottle 318 to filter impurities in the recycled high-viscosity damping oil and ensure the cleanliness of the high-viscosity damping oil. At the same time, an inclined oil collection pipe 319 is connected to the side of the oil collection bottle 318 to facilitate the flow of excess high-viscosity damping oil into the oil collection bottle 318. One end of the oil collection pipe 319 is connected to the side of the lower connecting seat 21 to provide an inflow channel for excess high-viscosity damping oil.

[0058] Working Principle: When the fan vibrates during operation, the vibration force is transmitted to the connector 27 through the mounting base 110, causing the upper connecting base 23 to move. At this time, the protrusion 231 at the bottom of the upper connecting base 23 and the inner wall of the opening of the lower connecting base 21 undergo relative displacement. Due to the continuous supply of high-viscosity damping oil between the contact surfaces, the damping oil fills the gap between them. During the relative movement, on the one hand, the presence of the oil film avoids direct hard contact between the metal surfaces, eliminating stick-slip vibration and high-frequency noise caused by dry friction; on the other hand, the high-viscosity damping oil is forced to flow in the narrow gap, generating fluid shear resistance. This damping force is proportional to the relative speed, efficiently converting the mechanical energy of the vibration into fluid heat energy and dissipating it. This combination of fluid viscous energy dissipation and residual friction energy dissipation between solid surfaces achieves stable and long-lasting vibration reduction.

[0059] Meanwhile, the four sets of damping springs 24 between the lower connecting seat 21 and the upper connecting seat 23 will be compressed. The damping springs 24 are evenly distributed around the lower connecting seat 21, and can withstand the pressure synchronously and evenly. They further absorb the vibration energy by utilizing their own elastic deformation, and initially buffer the vibration impact force. During this process, the guide rod 25 provides guidance for the up and down movement of the upper connecting seat 23 to prevent it from deviating. The anti-detachment end of the guide rod 25 prevents the upper connecting seat 23 from separating from the guide rod 25, ensuring the integrity of the shock absorption structure.

[0060] During this process, the contact ball rod 38 of the side connection end 37 of the upper connecting seat 23 moves with the upper connecting seat 23, contacts the pressing end 34 of the pressing part, and pushes the pressing end 34 to move upward. The upward movement of the pressing end 34 drives the crank arm 33 to rotate around the connecting shaft on the concave frame 32. When the crank arm 33 rotates, it pulls the piston rod 313 to move upward inside the cylinder 312, so that a negative pressure is formed inside the cylinder 312. Under negative pressure, the high-viscosity damping oil in the high-viscosity damping oil bottle 39 is drawn into the cylinder 312 through the oil outlet pipe 310. When the vibration and impact force weakens, the upper connecting seat 23 is reset under the action of the damping spring 24 and the pre-tightening spring 26. The contact ball rod 38 is disengaged from the crimping end 34. Under the prestress of the return spring 36, the crimping end 34 always maintains dynamic contact with the contact ball rod 38 to ensure the continuity of the suction action. The crank arm 33 rotates in the opposite direction under the action of the return spring 36, pushing the piston rod 313 downward to press the high-viscosity damping oil in the cylinder 312 into the annular oil storage tank 320 through the oil outlet pipe 314, the oil nozzle 317 and the hard oil pipe.

[0061] The high-viscosity damping oil entering the annular oil storage tank 320 is guided by gravity and the slope of the oil drain trough, and uniformly wets the surface of the protrusion 231 through multiple sets of circumferentially distributed inclined drain holes 321. This process ensures the balance of the liquid film damping layer in the damping gap and prevents interface dry friction and damping attenuation caused by oil film rupture.

[0062] Thus, during the cyclical vibration of the wind turbine, the damping maintenance component 3 utilizes the mechanical energy of the wind turbine vibration to automatically replenish the high-viscosity damping oil. This not only solves the problem of traditional dry friction damping failing due to wear, but also achieves a stable damping effect through a solid-liquid mixed viscous damping mechanism, in conjunction with the damping spring 24 and the preload spring 26.
