Abstract
The present invention provides a kind of subway ventilation smoke evacuation system, it includes website exhaust system and tunnel exhaust system, it is isolated between website and tunnel by shield door, so that website itself constitutes enclosure space, the website exhaust system includes air-conditioner host and be connected to extraneous exchange air duct, and the tunnel exhaust system includes several air ports for being opened in tunnel top；Wherein, several air ducts being connected to are opened up between the website and the tunnel, solenoid valve is installed, the solenoid valve is controlled by processor and opened and closed, and smoke alarm is installed in website in the air duct, when occurring smog in website, processor controls solenoid valve and opens, while sending warning message to control centre, and control centre's control train ignores the website and continues to move ahead, it controls shield door simultaneously and closes always, generated piston principle takes smog away under high-speed cruising state in tunnel using subway.The subway ventilation smoke evacuation system has the advantages that design science, smoke exhaust efficiency are high, extend evacuation time.
Description
Technical field
The present invention relates to a kind of subway security devices, specifically, relate to a kind of subway ventilation smoke evacuation system.
Background technique
In terms of subway is taken precautions against natural calamities, the influence of fire is the most serious, to find out its cause, being that thick fog caused by fire can not be arranged
Out, and in subway crowd is concentrated mainly in website, and smog is once diffused to website, and meeting Fast Filling website space will lead to
Serious catastrophic effect.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, to provide, a kind of design science, smoke exhaust efficiency is high, extends
A kind of subway ventilation smoke evacuation system of evacuation time.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of subway ventilation smoke evacuation system, including station
Point exhaust system and tunnel exhaust system, are isolated between website and tunnel by shield door, so that website itself constitutes closing sky
Between, the website exhaust system includes air-conditioner host and be connected to extraneous exchange air duct, and the tunnel exhaust system includes several
It is opened in the air port of tunnel top；Wherein, several air ducts being connected to are opened up between the website and the tunnel, in the air duct
Solenoid valve is installed, the solenoid valve is controlled by processor and opened and closed, and smoke alarm is installed in website, when occurring smog in website
When, processor controls solenoid valve and opens, while sending warning message to control centre, and control centre's control train ignores the website
Continue to move ahead, while controlling shield door and closing always, generated piston is former under high-speed cruising state in tunnel using subway
Reason takes smog away.
Described on base, it further includes the exhaust fan being arranged in outside air port.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, and specifically, the present invention will
It is separated between subway station and tunnel by shield door, when occurring fire in tunnel, smog is unlikely to permeate in website,
Before burning shield door, there is time enough to allow passenger evacuation；When fire occurs in website, connection tunnel and website are opened
Between solenoid valve, tunnel is connected with website space, at the same control train ignore the website move ahead, using train in tunnel
It runs at high speed generated piston effect, negative pressure state is kept in tunnel when train passes through site location, by the cigarette in website
Mist sucks in tunnel, achievees the purpose that alleviating website smog accumulates, and extends the time that smog is full of website, and then extend passenger's
Evacuation time is made contributions for nervous rescue work.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of subway ventilation smoke evacuation system in the present invention.
In figure: 1. tunnels；2. website；3. shield door；4. solenoid valve；5. air port；6. air duct.
Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
As shown in Figure 1, a kind of subway ventilation smoke evacuation system, including website exhaust system and tunnel exhaust system, website 2 with
It is isolated between tunnel 1 by shield door 3, so that website 2 itself constitutes enclosure space.Can guarantee that fire occurs in tunnel 1 in this way
When calamity, smog will not be diffused into website 2, before burning shield door 3, with respect to being all safe, the evacuation of crowd in website 2
Time is extended, and the crowd of avoiding comes to harm.
The website exhaust system includes that air-conditioner host (is cut not with extraneous exchange air duct is connected to due to belonging to routine techniques
It is related to main point of application, is not drawn into figure), the tunnel exhaust system includes several air ports 5 for being opened in 1 top of tunnel, is used for
Air circulation in daily website 2 and tunnel 1, meanwhile, when fire occurs for website 2, which is opened to maximum, as far as possible
Take smog away.
Several air ducts 6 being connected to are opened up between the website 2 and the tunnel 1, and solenoid valve 4, institute are installed in the air duct 6
It states solenoid valve 4 and opening and closing is controlled by processor, smoke alarm is installed in website 2, when occurring smog in website, processor control
Solenoid valve 4 is opened, while sending warning message to control centre, and control centre's control train ignores the website and continues to move ahead, together
When control shield door close always, using subway, generated piston principle takes out smog under high-speed cruising state in tunnel
It walks, subway generates huge negative pressure in tunnel 1 when train is run at high speed by website 2, and under the action of negative pressure, smog is from electricity
Tunnel 1 is sucked in the air duct 6 that magnet valve 4 is controlled, and is delayed smog to fill up the time of website 2, is extended the duration of Evacuation, tight
In the rescue time opened, rescue rate is effectively improved.
Exhaust fan is set outside air port 5, the smog into tunnel is slowly discharged from air port 5 under the action of exhaust fan.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
