Vibration isolation system for cooling tower

Abstract

The invention discloses a vibration isolation system for a cooling tower. The vibration isolation system comprises a floating plate and a vibration isolation assembly. The vibration isolation assemblycomprises a main vibration isolator corresponding to the middle of the floating plate, and at least one auxiliary vibration isolator corresponding to the side of the floating plate. The main vibration isolator comprises a magnetorheological torsion damper and a motion conversion mechanism. The motion conversion mechanism is used for converting linear motion generated by vibration into rotary motion, so that the magnetorheological torsion damper restrains vibration. The motion conversion mechanism comprises a rack for bearing vibration load, and a gear for converting linear motion of the rackinto rotary motion. The upper end of the rack is vertically fixed to the lower surface of the floating plate, and the lower end of the rack is matched with a guide seat of a building foundation. The gear is fixedly connected to a rotary shaft of the magnetorheological torsion damper and rotates synchronously. Through the vibration isolation system, vibration of the cooling tower can be lowered effectively, meanwhile vibration is prevented from being transmitted into a building structure, vibration of walls or floors or ceilings of rooms is avoided, and thus a noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the field of cooling tower components, in particular to a vibration isolation system for a cooling tower. Background technique [0002] Due to the increasing shortage of urban land, residential, office and commercial high-rise buildings have become the main development trend of urban architecture. In these high-rise buildings, the cooling tower is a kind of conventional construction equipment, often placed in the basement or roof of the building. The cooling tower will vibrate during operation. The vibration of the cooling tower can easily pass through the foundation and the pipes connected to the cooling tower or Cables, etc. propagate to building structures to which they are connected. Due to the small damping of the concrete structure or steel structure, the structure has little attenuation of vibration. Once the vibration of the cooling tower is transmitted to the building structure, its vibration will spread in a wide ran...

Problems solved by technology

When the vibration is transmitted to the noise-sensitive use space, it will cause the wall, floor or ceiling of the room to vibrate, thereby radiating noise into the room, reducing the comfort of building use, and affecting the work and rest of users
