| description | The utility model belongs to the technical field of ventilation devices, and particularly relates to a ventilation device for quickly diluting locally accumulated gas, which comprises a mounting frame and a driving component, a mounting cylinder is rotatably arranged on the right half part of the transverse mounting frame in a penetrating manner, and the mounting cylinder is in a hollow cylinder shape with open upper and lower side walls. The top end of the installation cylinder is located on the ground and communicated with the outside, the bottom end of the installation cylinder is located in the tunnel, the installation cylinder is rotated into the top wall in the tunnel through the installation nails to fix the device, the air suction fan is started through the controller, the air suction fan sucks outside air into the tunnel, and therefore gas locally accumulated in the tunnel is diluted, and meanwhile the exhaust pipe is started. The exhaust pipe pumps gas in the tunnel to the outside, so that the conce |
