A high-efficiency clean and ventilated structure for high-rise buildings

Abstract

The invention relates to the technical field of building ventilation, in particular to a high-efficiency clean ventilation structure for high-rise buildings, which includes a first ventilation pipe and a second passage pipe which are slid and socketed with each other along the flow direction of the ventilation airflow, the first ventilation pipe and the second passage pipe There is a telescopic adjustment mechanism that controls the expansion and contraction of the first ventilation pipe and the second passage pipe. The first ventilation pipe is provided with a filter screen, the second passage pipe is provided with a ventilation fan, and the top of the first ventilation pipe is provided with a lifting device. Cleaning mechanism, the cleaning mechanism cleans the filter screen, a blocking mechanism is arranged in the second ventilation pipe, the blocking mechanism is located on the front side of the ventilation fan, when the filter screen is cleaned, the blocking mechanism blocks the second ventilation pipe, and by using the cleaning mechanism The roller brush assembly and the air blowing assembly in it cooperate to collect the dust cleaned from the filter screen into the dust collection assembly in a timely manner, avoiding the scattering of the cleaned dust, and also avoiding the dust rewinding when the ventilation structure is restarted.

Description

technical field [0001] The invention relates to the technical field of building ventilation, in particular to a high-efficiency clean ventilation structure for high-rise buildings. Background technique [0002] Building ventilation is divided into natural ventilation and mechanical ventilation. It means that the dirty air in the building is directly or purified and discharged to the outside, and then fresh air is added in, so as to keep the indoor air environment in line with hygienic standards, especially in high-rise buildings. Due to the height, there is a big difference from the conventional ventilation structure. It is necessary to open the mechanical ventilation structure for a long time to ensure the hygienic standard of the indoor air. However, the connection between the ventilation device and the ventilation pipe of the existing high-rise building is more troublesome. , mostly fixed by bolts or screws, the positioning accuracy is poor and the connection stability is...
