Abstract

The invention belongs to the technical field of tunnel traffic and in particular relates to a ventilation device for tunnel traffic. For a problem that ventilation equipment for a traffic tunnel cannot perform emergency treatment on fire disasters, the following scheme is provided. The ventilation device for tunnel traffic comprises a ventilation tube; vertically placed fixing plates are mounted on the two sides between both the top and the bottom of the circumferential internal wall of the ventilation tube through bolts; a same horizontally placed fixing rod is welded in a middle positions ofthe two fixing plates; and mounting rings are mounted on the two sides of the circumferential external wall of the fixing rod through bearings. According to the ventilation device for tunnel traffic,when fire disasters occur, the temperature in an air outlet cavity is increased to form a pressure difference with the air in an air inlet cavity, and therefore, a first partition plate and a secondpartition plate shifts to one side of the air inlet cavity, the aperture of the air inlet cavity is reduced, the air feeding of an air inlet tube is reduced to block the spreading of a fire source, and meanwhile, the aperture of the air outlet cavity is increased to increase the air outlet amount so as to improve air exhaust and smoke dust discharging effects, and therefore, the ventilation tube performs emergency treatment when fire disasters occur.

Description

technical field [0001] The invention relates to the technical field of tunnel traffic, in particular to a ventilation device for tunnel traffic. Background technique [0002] With the development of transportation facilities, the ground traffic is gradually moving underground, and the traffic tunnel is gradually taking shape. In addition to the main building of the cylindrical structure, the traffic tunnel also needs to be installed with other auxiliary equipment to ensure the normal traffic in the cave. The auxiliary equipment includes lighting Equipment, drainage equipment and ventilation equipment, etc. Among them, the ventilation equipment is for the ventilation in the tunnel, and the ventilation equipment used in the traffic tunnel is mainly composed of air ducts and fans. [0003] In the traffic tunnel, two pipes are used to make the external wind flow through the tunnel, and the two pipes are connected to the interior of the tunnel by setting up equidistant fans to re...
