Building fan vibration reduction system

Abstract

The invention discloses a building fan vibration reduction system. The building fan vibration reduction system comprises a fan body and a vibration reduction support seat; the vibration reduction support seat comprises a floating slab, a vibration reduction top plate and a vibration reduction bottom plate which are arranged from top to bottom in sequence; the top face of the floating slab is fixedly connected with the bottom face of a first rubber vibration reduction cushion, the bottom face of the floating slab is fixedly connected with one end of each of hydraulic rods, the other ends of thehydraulic rods are fixedly connected with the top face of a rectangular metal slide block, and a horizontal supporting rod is arranged between every two adjacent hydraulic rods; the top face of the vibration reduction top plate is provided with a rectangular slide groove, the rectangular metal slide block is embedded in the rectangular slide groove and is slidably connected with the vibration reduction top plate, the side wall of the rectangular slide groove is fixedly connected with one end of a first vibration reduction spring, and the other end of the first vibration reduction spring is fixedly connected with the side wall of the rectangular metal slide block; and the center of the bottom of the vibration reduction top plate is provided with an upper buffering seat, and the bottom of the upper buffering seat is provided with a convex face. The building fan vibration reduction system can effectively relieve vibration transmitted to a building by a fan, so that the building structureis protected, and noise pollution is reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a vibration reduction system for a construction fan. Background technique [0002] Building equipment refers to all technical measures applicable to rooms and buildings, including energy (heating, lighting) and supply (water, air) or waste discharge (sewage, garbage) of premises and public places, the purpose of which is to provide The normal use and necessary safety of the building. The building fan is a kind of key building equipment; the fan relies on the input mechanical energy to increase the gas pressure and discharge the gas, so as to provide ventilation performance for the building; the fan is generally installed on the roof of the building, and it generates large vibration during work, which is easy to Harm the building structure and interfere with the environment; at present, a vibration reduction system is generally installed between the fan and the building.
