Problems solved by technology
[0003] Especially in expressway tunnels with many large diesel transport vehicles, the air in the tunnel is dirty and the content of harmful gases exceeds the standard. Ventilation requirements during operation
Therefore, an exhaust device will be built on the tunnel to increase the circulation of air in the tunnel, but in the event of an emergency power failure, the tunnel cannot be exhausted, which will cause a lack of oxygen, and there are certain requirements for the air discharge speed, otherwise it will be difficult Realize the use of emergency exhaust

The invention discloses a tunnel emergency air exhaust combined fan which comprises emergency air exhaust devices, a laser speed measuring device, a main transmission shaft, a motor, an energy storage device and a speed reducer, the emergency air exhaust devices are symmetrically arranged relative to the main transmission shaft, the centers of the emergency air exhaust devices are connected with the main transmission shaft, the output end of the motor is connected with the main transmission shaft, and the laser speed measuring device is arranged on the laser speed measuring device. The speed reducer and the energy storage device are sequentially connected to the other end of the main transmission shaft, and the laser speed measuring device is arranged on the main transmission shaft and used for measuring speed. The invention belongs to the technical field of tunnel emergency fans, and particularly provides a tunnel emergency exhaust combined fan which detects the exhaust speed through laser speed measurement and ensures stable operation of equipment while increasing the exhaust speed through energy storage and a speed reducer after the exhaust speed is not met and a using method thereof.
Description
technical field [0001] The invention belongs to the technical field of tunnel emergency fans, in particular to a tunnel emergency exhaust air combined fan and a method of using the same. Background technique [0002] At present, most of the tunnel operation ventilation adopts the vertical ventilation mode of jet fans. Most of the jet fans are hung on the tunnel vault, and a few are hung on the side walls through embedded parts. The installation is difficult, the maintenance operation is more complicated, and there is a risk of falling. It is also very inconvenient for the construction of secondary lining concrete in the tunnel. With the rapid development of the national economy, the demand for transportation is increasing, and the construction of extra-long tunnels and super-extra-long tunnels of more than 10 kilometers is increasing. The ventilation problem during the operation period of long tunnels has not been well solved. [0003] Especially in highway tunnels with man...
