Movable lateral smoke exhaust device in tunnel

Abstract

The invention discloses a movable lateral smoke exhaust device in a tunnel. Funnel-shaped smoke exhaust ducts are arranged on the upper part of the side wall of the tunnel at equal intervals; double sliding rails are arranged at the bottoms of smoke inlets of the funnel-shaped smoke exhaust ducts and the intervals between every two funnel-shaped smoke exhaust ducts, and movable baffles are arranged on the double sliding rails in parallel by pulleys; drive motors are arranged on the movable baffles, through the cooperation of the pulleys and the sliding rails, the movable baffles arranged in parallel form a shielding structure at the smoke inlets, and smoke exhaust ports are formed at the unshielded smoke inlets. Smoke can be quickly and efficiently exhausted from the tunnel, human casualties and loss can be reduced, and the rescue efficiency is improved.

Description

technical field [0001] The invention belongs to the related technical field of tunnel ventilation and smoke exhaust, in particular to a movable side smoke exhaust device in a tunnel. Background technique [0002] 1. With the increasing demand for national transportation, the construction of tunnels such as highways and railways is also gradually increasing, and the problem of tunnel fires is also subject to more and more problems. Highway tunnel fires cause great harm, especially for long and extra-long tunnels. After a fire occurs, there will be a large amount of smoke in the tunnel, low visibility, slow heat dissipation, and high temperature. Especially when a fire occurs in a highway tunnel with a large traffic flow, evacuation is difficult due to the low visibility in the tunnel. Therefore, smoke prevention and exhaust in tunnel fires are an important part of ventilation design. [0003] 2. Under the tunnel longitudinal ventilation mode, the fire smoke will fill the ent...

Problems solved by technology

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a movable side smoke exhaust device in the tunnel, in order to effectively solve the problem of smoke sinking in the conflict area formed by the smoke and the flow of people in the same direction, and Quickly and efficiently discharge fire smoke from the tunnel, thereby reducing the impact of fire on personal safety and tunnel traffic, improving rescue efficiency, and can be used for experimental test simulations. Carry out model experiment research that satisfies the similarity theory, and reveal the side effects of tunnel fires. Flue gas flow law to exhaust
