Abstract

The invention discloses a steerable jet fan for tunnels, which includes a fan and a steering hanger. The fan includes an air duct. Two connecting protrusions are formed on the upper outer wall of the air duct, and a rectangular groove is formed on the connecting protrusions; The steering hanger includes a hanger base fixed on the inner wall of the tunnel. A support column is fixed at the bottom of the hanger. A rotary table is hinged to the support column. A worm gear is fixed in the middle of the support column. The worm gear is engaged with a worm, and the worm is connected to the second motor; Two pulling arms arranged symmetrically on the left and right are fixed on the outer wall of the rotating table. The lower ends of the pulling arms are formed with rectangular plates that match the rectangular grooves, and the rectangular plates are inserted into the rectangular grooves. The present invention can steer the fan through the steering hanger, thereby realizing two-way ventilation of the fan, and the fan structure is compact and easy to install.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a steerable jet fan for tunnels. Background technique [0002] In subway tunnels, in order to discharge carbon dioxide, sulfur dioxide and other waste gases in the tunnel and introduce fresh air from the outside, it is usually necessary to install several rows of jet fans on the top wall of the tunnel for ventilation. At the same time, in order to achieve two-way ventilation, jet fans usually Two-way reversible form is adopted. However, the two-way reversible jet blower is inconvenient to transport and install due to the large mass and volume of the blower at both ends. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a steerable jet fan for tunnels, which can steer the fan through the steering hanger, so as to realize the two-way ventilation of the fan, and the fan has a compact structure and is ...
