Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and air exchange, in particular to a ventilation and air exchange device inside a tunnel. Background Art

[0002] In the early days, people relied primarily on natural ventilation to exchange indoor and outdoor air, for example, by allowing air to flow naturally through openings like windows and doorways. However, the effectiveness of this type of ventilation was significantly limited by factors such as climate and building layout. With the advent of the Industrial Revolution, factories and buildings continued to expand, and the demand for ventilation also increased. Simple natural ventilation could no longer meet this demand, and mechanical ventilation devices began to emerge. The initial mechanical ventilation equipment was relatively simple, primarily fans with a single function and crude control over wind direction and speed.

[0003] A search revealed a Chinese utility model patent publication numbered CN208816165U, which discloses a tunnel internal ventilation device comprising a tunnel wall, a door, and a through hole. The tunnel wall comprises an air inlet duct, the lower end of which is connected to an air outlet duct, a fan mounted on the right side of the air outlet duct, and a filter fixed to the middle of the air outlet duct. A block is provided above the filter, and a rotating shaft A is mounted below the filter, extending through the interior of the baffle. The rotating shaft B extends through the interior of an inclined rod, and a connecting shaft is connected to the lower end of the inclined rod. A slide is provided within the screw, and a groove is reserved on the inner surface of the slide. The door is located at the lower left end of the air outlet duct, a magnet A is provided at the lower right end of the air outlet duct, and a magnet B is mounted on the outside of the door. The through hole is located directly in front of the door. The tunnel internal ventilation device has a through hole in the door, which serves to ventilate the air while preventing foreign matter from entering the air outlet duct and damaging the filter.

[0004] However, the device lacks a dehumidification function. When in use, moisture in the air will damage the device, causing the ventilation device to be corroded by moisture and affecting the service life of the device. Not only that, the device lacks a noise reduction function. When the ventilation function is started, the noise is too loud, causing noise pollution to the environment. Utility Model Content
