Description

A vibration isolation device for cooling tower fans Technical Field

[0001] This utility model relates to the field of fan vibration isolation technology, specifically a cooling tower fan vibration isolation device. Background Technology

[0002] In industrial production, cooling towers are key equipment used to reduce the temperature of circulating water, and cooling tower fans are one of their core components, responsible for providing sufficient airflow to dissipate heat. However, cooling tower fans generate significant vibrations during operation. These vibrations are not only transmitted to the structural components of the cooling tower, leading to fatigue damage and a shortened lifespan, but can also cause noise pollution, affecting the surrounding environment and the health of workers.

[0003] Traditional vibration reduction measures for cooling tower fans typically employ simple rubber pads or spring supports, but these methods have the following shortcomings:

[0004] Limited vibration reduction effect: While traditional rubber pad vibration reduction methods can absorb some high-frequency vibrations, their isolation effect on low-frequency vibrations is poor. Although spring supports can provide some buffering, they are prone to resonance under complex working conditions, which can actually exacerbate vibrations.

[0005] Poor structural stability: During long-term operation, rubber pads are prone to aging and deformation, and springs may also fail due to fatigue, leading to a decline in vibration damping performance and even the risk of equipment loosening or displacement.

[0006] Inconvenient installation and adjustment: Traditional vibration damping devices usually require a complex installation process and are difficult to adjust and maintain effectively during equipment operation, increasing equipment maintenance costs and downtime.

[0007] Therefore, a vibration isolation device for cooling tower fans is needed to improve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a vibration isolation device for cooling tower fans to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A vibration isolation device for a cooling tower fan includes an upper fixed ring and a lower fixed ring. A plurality of swing rods are fixedly provided at the lower end of the upper fixed ring, and a metal ball is fixedly provided at one end of each swing rod. A plurality of upper sleeves are hinged to the surface of the upper fixed ring, and a plurality of lower sleeves are hinged to the surface of the lower fixed ring. A vibration damping mechanism is fitted inside the lower sleeves and the upper sleeves.

[0011] As a preferred embodiment of this utility model, the surface of the upper fixing ring is provided with a plurality of bolt holes, and the bolt holes are fixed to the fan by bolts.

[0012] As a preferred embodiment of this utility model, the surface of the lower fixing ring is provided with a plurality of bolt holes II, which are fixed to the cooling tower by bolts.

[0013] As a preferred embodiment of this utility model, the shock absorption mechanism includes a sliding rod, a sliding plate, a sliding sleeve, a spring, and a through hole.

[0014] As a preferred embodiment of this utility model, the sliding sleeve is inserted into the inner side of the lower sleeve, and the sliding rod is inserted into the inner side of the upper sleeve.

[0015] As a preferred embodiment of this utility model, the sliding rod is slidably disposed inside the sliding sleeve, and a sliding plate is fixedly provided at one end of the sliding rod located inside the sliding sleeve.

[0016] As a preferred embodiment of this utility model, a spring is fixedly provided on the inner side of the sliding sleeve, the sliding plate is fitted and connected to the spring, and the surface of the sliding plate is provided with a through hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. High-efficiency vibration isolation performance:

[0019] Through the design of the swing rod and metal ball, the device can effectively absorb and disperse the high-frequency vibration generated during the operation of the fan, reduce the energy of vibration transmitted to the cooling tower structure, and the springs and sliding plates in the damping mechanism and the through holes on their surfaces further buffer and absorb the vibration, significantly reducing the vibration amplitude and improving the operational stability of the cooling tower.

[0020] 2. Compact structure and easy installation:

[0021] The upper and lower fixing rings are fixedly connected to the fan and cooling tower respectively through bolt hole one and bolt hole two. The installation process is simple and quick, without the need for complicated welding or special tools. The hinge connection design of the upper and lower sleeves allows the device to adapt to different angle installation requirements, enhancing the versatility and flexibility of the device.

[0022] Highly adaptable:

[0023] The sliding fit design of the sliding rod and the sliding sleeve allows the damping mechanism to automatically adjust the buffering force according to the actual vibration conditions, adapting to the vibration frequency and amplitude under different working conditions. The through hole design not only reduces the weight of the sliding plate, but also increases airflow, further optimizing the damping effect. Attached Figure Description

[0037] Please refer to Figures 1-7. This utility model provides a technical solution:

[0038] A vibration isolation device for a cooling tower fan includes an upper fixed ring 1 and a lower fixed ring 2. A plurality of swing rods 5 are fixedly mounted on the lower end of the upper fixed ring 1, and a metal ball 6 is fixedly mounted on one end of each swing rod 5. A plurality of upper sleeves 7 are hinged to the surface of the upper fixed ring 1, and a plurality of lower sleeves 9 are hinged to the surface of the lower fixed ring 2. A damping mechanism 3 is fitted inside the lower sleeves 9 and the upper sleeves 7. Through the counterweight effect of the swing rods 5 and the metal ball 6, and the buffering function of the damping mechanism 3, the vibration generated during fan operation can be effectively reduced, protecting the structural stability of the cooling tower.

[0039] As an example of this utility model, the upper fixing ring 1 has several bolt holes 4 on its surface, and the bolt holes 4 are fixed to the fan by bolts. The design of the bolt holes 4 enables the upper fixing ring 1 to be firmly connected to the fan by bolts, ensuring the stability of the fan during operation.

[0040] As an example of this utility model, the surface of the lower fixing ring 2 is provided with a plurality of bolt holes 8, which are fixed to the cooling tower by bolts. The design of the bolt holes 8 enables the lower fixing ring 2 to be firmly connected to the cooling tower by bolts, ensuring a stable connection between the vibration isolation device and the cooling tower.

[0041] As an example of this utility model, the shock absorption mechanism 3 includes a sliding rod 10, a sliding plate 11, a sliding sleeve 12, a spring 13, and a through hole 14. These components together constitute a mechanical structure that can effectively absorb and buffer vibrations. Vibration reduction is achieved through the elastic action of the spring 13 and the sliding of the sliding plate 11.

[0042] As an example of this utility model, the sliding sleeve 12 is inserted inside the lower sleeve 9, and the sliding rod 10 is inserted inside the upper sleeve 7. The design of the sliding sleeve 12 and the sliding rod 10 allows the shock-absorbing mechanism 3 to slide flexibly within the upper and lower sleeves, ensuring the stability of the shock-absorbing effect.

[0043] As an example of this utility model, the sliding rod 10 is slidably disposed inside the sliding sleeve 12, and a sliding plate 11 is fixedly provided at one end of the sliding rod 10 inside the sliding sleeve 12. The design of the sliding plate 11 enables the sliding rod 10 to slide smoothly within the sliding sleeve 12, while closely fitting with the spring 13 to ensure the buffering effect of the shock absorption mechanism 3.

[0044] As an example of this utility model, a spring 13 is fixedly provided on the inner side of the sliding sleeve 12, and the sliding plate 11 is fitted and connected to the spring 13, and the surface of the sliding plate 11 is provided with a through hole 14. The elastic effect of the spring 13 can effectively absorb vibration energy, and the through hole 14 on the sliding plate 11 ensures air circulation during the sliding process, further improving the shock absorption effect.

[0045] Working principle: During use, vibration transmission and initial buffering occur.

[0046] When the cooling tower fan is running, vibrations are generated. These vibrations are first transmitted to the upper fixed ring 1 through the fan. Since the lower end of the upper fixed ring 1 is fixed with a swing rod 5, the metal ball 6 at one end of the swing rod 5 can buffer and disperse the vibration energy to a certain extent, playing a preliminary shock absorption role.

[0047] The function of a multi-stage damping mechanism:

[0048] The vibration energy is further transmitted to the upper sleeve 7 and the lower sleeve 9. Since the upper sleeve 7 and the lower sleeve 9 are equipped with a damping mechanism 3, the vibration energy will act on the damping mechanism 3.

[0049] The vibrational energy is first applied to the sliding rod 10, which slides within the sliding sleeve 12. A sliding plate 11 at one end of the sliding rod 10 is in contact with a spring 13. When the sliding rod 10 slides, the sliding plate 11 compresses the spring 13, and the spring 13 absorbs and buffers the vibrational energy through elastic deformation.

[0050] The design of the through hole 14 ensures the smooth sliding of the sliding rod 10 within the sliding sleeve 12, and also helps to adjust the damping effect of the shock absorption mechanism 3, further optimizing the shock absorption performance.

[0051] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
