Efficient cleaning and ventilating structure for high-rise building

Abstract

The invention relates to the technical field of building ventilation, in particular to an efficient cleaning ventilation structure for a high-rise building. The efficient cleaning ventilation structure comprises a first ventilation pipe and a second channel pipe which are in sliding sleeve connection with each other in the ventilation airflow flowing direction, a stretchable adjusting mechanism for controlling the first ventilation pipe and the second channel pipe to stretch out and draw back is arranged between the first ventilation pipe and the second channel pipe, a filter screen is arranged in the first ventilation pipe, a ventilation fan is arranged in the second channel pipe, a clearing mechanism arranged in a lifting mode is arranged at the top of the first ventilation pipe, the clearing mechanism cleans the filter screen, a blocking mechanism is arranged in the second ventilation pipe and located on the front side of the ventilation fan, and when the filter screen is cleaned, the blocking mechanism blocks the second ventilation pipe. Dust cleared from the filter screen is timely collected into a dust collection assembly through the cooperation of a rolling brush assembly and an air blowing assembly in the clearing mechanism, the cleared dust is prevented from flying away, and the dust is also prevented from being rolled back when the ventilation structure is started again.

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...
