[0002] Underground space refers to the space below the surface of the earth, including naturally formed caves and artificially developed underground buildings. Underground space refers to the area below the surface of the earth, which can be naturally formed, such as natural caves, or artificially excavated or constructed, such as basements and tunnels. According to different functions, underground space can be divided into transportation facilities (such as subways), commercial facilities (such as underground shopping malls), municipal public welfare pipeline facilities (such as underground pipe networks), etc. A ventilation device for underground space is needed to have the advantages of protective performance, economy and stability.

[0003] In the prior art, a ventilation device for an underground space generally includes a ventilation duct and a fan. The fan and the ventilation duct are fixedly connected by bolts. By starting the fan, the air in the underground space can be replaced to ventilate the underground space.

[0004] However, when the above device is in use, it relies on the fan to make the air flow, and a lot of dust in the underground space will be discharged to the ground space along with the flow of the air, which will cause certain pollution to the ground environment. Utility Model Content
