Abstract

The utility model relates to a tunnel air circulation device which comprises a driving shell, a fixed support, an air circulation assembly and a blocking mechanism. The fixed support is fixed in the driving shell and is used for fixing the driving shell in a tunnel; the air circulation assembly is installed in the driving shell and used for circulating air in the tunnel. The blocking mechanism is coaxially installed at the end of the driving shell and connected with the air circulation assembly. When the tunnel air circulation equipment is used, the blocking equipment can be driven by the air circulation assembly to clean sundries in time, so that the air circulation efficiency is improved, meanwhile, the sundries on the blocking mechanism can be quickly cleaned, and the cleaning efficiency is improved.
