Self-adaptive ventilation device used for healthy building and utilizing natural wind

Abstract

The invention discloses a self-adaptive ventilation device using natural wind for a healthy building. The self-adaptive ventilation device comprises a horizontally-placed funnel-shaped wind collecting cover, and a shutter wind opening is formed in the outlet end of the wind collecting cover; the lower wall of the air collecting cover communicates with a vertically-arranged follow-up air inlet pipe. A wind direction follower plate is vertically mounted at the upper end of the tail part of the wind collecting cover; the air direction follow-up plate and the inlet end of the air collecting cover are located on the two sides of the follow-up air inlet pipe respectively; a fixed air inlet pipe is fixedly mounted in the wall body; the follow-up air inlet pipe and the fixed air inlet pipe are rotationally connected through the rotating pipe joint; and the fixed air inlet pipe is communicated with the indoor air inlet pipe. Indoor air circulation can be well achieved through outdoor natural air, and compared with a traditional mechanical ventilation device, the ventilation device is more energy-saving and environmentally friendly and is widely suitable for common buildings and healthy buildings such as medical buildings.

Description

technical field [0001] The invention relates to the technical field of building ventilation, in particular to an adaptive ventilation device using natural wind for healthy buildings. Background technique [0002] With the acceleration of urban construction, the number of high-rise buildings is obviously increasing. Air ducts are formed between high-rise buildings, and the air ducts generate strong natural wind force. In order to reduce the impact of strong wind and wind dust on the interior of the houses on both sides of the air duct, the doors and windows usually have to be closed tightly, resulting in indoor air not circulating, which is not conducive to human health. Therefore, it is necessary to use a mechanical ventilation device to assist ventilation. In the long run, the power consumption is relatively large, which is not enough for energy saving and environmental protection. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the prese...
