Wind direction changing mechanism for energy-saving building ventilation device

Abstract

The invention discloses a wind direction changing mechanism for an energy-saving building ventilation device. The wind direction changing mechanism comprises a building device, circular openings are formed in the outer surfaces of the two sides of the building device correspondingly, cavities are formed in the positions, located below the circular openings, of the two sides of the building devicecorrespondingly, and first buffer plates are fixed to the bottom faces of the interiors of the two cavities correspondingly. According to the wind direction changing mechanism for the energy-saving building ventilation device, when a circular ring plate rotates, a second short rod can drive a rotating circular plate to stably rotate in a circular sliding groove, so that the circular ring plate canstably rotate, and through rotation of a plurality of sliding balls, the rotating friction force between the rotating circular plate and the circular sliding groove can be reduced, so that the circular ring plate can be better rotated; and when the circular plate rotates, a ventilation fan is rotated, the wind direction of the ventilation fan can be changed, and in use, the building device is convenient to ventilate, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of building ventilation devices, in particular to a wind direction changing mechanism for an energy-saving building ventilation device. Background technique [0002] The scale of modern buildings is getting bigger and bigger. Although the area of ​​glass curtain walls is getting bigger and bigger, due to the needs of safety and beauty, the area that can be opened is usually very small, and the windows are basically closed during use, so for In many modern buildings, the effect of natural ventilation is very poor, especially for some large buildings, there is basically no natural ventilation. In order to solve the problem of poor indoor air quality, most modern buildings use mechanical ventilation. Most of the common building ventilation devices are The fan is driven by domestic electricity for ventilation. [0003] However, the position of the existing ventilation device is directly fixed in use, and the wi...
