Abstract

The invention discloses a reversible jet fan for a tunnel. The reversible jet fan comprises a fan and a reversing hanging bracket, wherein the fan comprises an air duct; two connecting bulges are molded on the outer wall of the upper side of the air duct; rectangular grooves are molded on the connecting bulges; the reversing hanging bracket comprises a hanging bracket base fixed to the inner wallof the tunnel; a supporting column is fixed to the hanging bracket base; the supporting column is hinged with a rotating platform; a worm gear is fixed to the middle of the supporting column; the wormgear is meshed with a worm; the worm is connected with a second motor; two pull arms which are arranged in a manner of bilateral symmetry are fixed to the outer wall of the rotating platform; rectangular plates cooperating with the rectangular grooves are molded at the lower end of the pull arms; and the rectangular plates are inserted and sleeved into the rectangular grooves. According to the reversible jet fan, the fan can be reversed by the reversing hanging bracket; thus, the two-way ventilation of the fan is realized; and further, the fan is small and exquisite in structure and convenient to mount.

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 ...
