Problems solved by technology

There are two types of smoke exhaust in tunnels: natural smoke exhaust and mechanical smoke exhaust. Natural smoke exhaust has a low cost and is widely used, but its reliability is poor; mechanical smoke exhaust is relatively expensive, but has better reliability.
When using mechanical centralized smoke exhaust, if the wind speed is too high, it will cause the phenomenon of suction through, so that the amount of smoke exhaust will be relatively reduced

Abstract

The invention discloses a plate-opening coupled type smoke discharging device and belongs to the technical field of tunnel smoke discharge. The plate-opening coupled type smoke discharging device comprises a fixing frame, a power source circuit module, an electromagnetic valve module, a gear bin module and a spoiler. The electromagnetic valve module, the gear bin module and the power source circuit module are fixed inside the fixing frame and form a complete circuit access. The fixing frame is fixed to the upper portion of a smoke discharge opening. The gear bin module is connected with the spoiler through a connection rope. The plate-opening coupled type smoke discharging device can change the smoke discharge gas flow angle according to different smoke coming conditions, optimizes a smokedischarge flow field, effectively reduces the influence of a plug-holing effect on the smoke discharge efficiency and improves the smoke discharge capacity.

Description

technical field [0001] The invention relates to the technical field of tunnel smoke exhaust, in particular to a plate-port coupled smoke exhaust device. Background technique [0002] A large part of the heat generated in a fire is carried and transported by fire smoke, so how to control the spread of smoke after a fire is an important issue. There are two types of smoke exhaust in tunnels: natural smoke exhaust and mechanical smoke exhaust. Natural smoke exhaust is low in cost and widely used, but its reliability is poor; mechanical smoke exhaust is relatively expensive but has better reliability. When using mechanical centralized smoke exhaust, if the wind speed is too high, it will cause the phenomenon of suction through, so that the amount of smoke exhaust will be relatively reduced. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a plate-port coupling type smoke exhaust device. [0004] The present inv...
