Description

technical field [0001] The invention belongs to the technical field of fans, and specifically refers to a vertically adjustable jet fan for tunnels and a method for using the same. Background technique [0002] Jet fan is a special axial flow fan, mainly used in the longitudinal ventilation system of tunnels such as roads, railways and subways; it can also be used in sensitive parts of semi-horizontal ventilation systems or transverse ventilation systems, such as the entrance and exit of tunnels, Play the role of inducing airflow or smoke exhaust. Under the existing technology, the angle of the ordinary jet fan cannot be adjusted, and sometimes some installation spaces have a certain slope, which cannot play a good role in inducing. At the same time, the inclination angle of the fan cannot be adjusted after the fan is installed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a jet fan for a tunnel that can be adjust...
