Description
Technical field
The invention belongs to lifesaving appliance, is related to a kind of tunnel fire proofing isolating device, refers in particular to a kind of inflatable tunnel and prevents
Fiery isolating device.
Background technology
With the development of economy and society, the tunnel traffic construction in China is also being spread out rapidly, 10 years before 21 century, China is public
Average annual 555 kilometers of " expediting the emergence of " tunnel is built on road.Since 2011, vcehicular tunnel has a net increase of every year has surpassed 1000 kilometers.Chinese building
The statistics that tunnels and underground engineering branch of Engineering society announces shows that China becomes world's tunnels and underground engineering construction scale
With the first big country of construction speed, so the safety problem in tunnel must cause our attention.Fire once occurs for tunnel, due to
Narrow space in tunnel, causes burning to be not thorough, and produces substantial amounts of toxic smog, and smog is easily spread at high temperature, is dredged to escape
Dissipate and put out a fire to save life and property and bring great difficulty, the security of the lives and property of serious threat escape personnel is destructive very big, causes human life
The major accident of injury.Therefore, in order to be reduced as far as casualties, it is necessary to corresponding firebreak device is set in tunnel,
To control fire, strive for more escape times to personnel.
The prior art monitors the generation of fire by setting monitoring and relevant warning device in tunnel, once hair
Light a fire calamity, fire-fighting system is triggered by alarm, such as fire hydrant, sprinkler are put out a fire, and are then by logical for big smog
Wind system is dispersed, while also it has been proposed that carrying out the isolation in fire section with fire resisting shutter or fire resisting shield.But
These devices have the following disadvantages：1st, since in the narrow space in tunnel, high temperature fumes are easily spread, by existing fire extinguishing
System can not effectively solve the problems, such as personnel because dense smoke suffocates, and fire can be encouraged while dense smoke is dispersed by ventilating system
Gesture, makes personnel be difficult to preferably escape.2nd, existing fire resisting shutter and fire resisting shield take larger space, and due to fire prevention
Roller shutter and fire resisting shield are all more thick and heavy, the process that fire resisting shutter and fire resisting shield are stretched out from tunnel edge after fire generation
In easily pound vehicle and escape personnel, cause secondary injury.
The content of the invention
It is an object of the invention in view of the above-mentioned problems, provide a kind of foldable built-in, easy to use, isolation effect it is good and
Safe and reliable inflatable tunnel fire proofing isolating device.
The purpose of the present invention can be reached using following technical scheme：
A kind of inflatable tunnel fire proofing isolating device, including divider wall, the divider wall are fire proofing material, on tunnel inner wall
End is provided with tank, and the divider wall is foldable to be installed in tank, and when fire occurring in tunnel, divider wall extends downwardly tank
And it is unfolded；Gas can be filled with the divider wall, after gas is filled with toward in divider wall, divider wall expands and seals up tunnel,
Enter tunnel to completely cut off air；The lower end of the divider wall is equipped with the passage that can be opened or closed, so that personnel are applied by passage
Rescue or escape, the passage is equipped with switching device.
As a preferred solution, the inner wall in the tunnel is equipped with the baffle that can open or cover tank, and drives
Dynamic device, when fire occurring in tunnel, the driving device driving baffle is opened and divider wall is extended downwardly tank and is opened up
Open.
As a preferred solution, the switching device includes cover board and axis pin, and the axis pin is installed vertically on passage
On the divider wall of top, the cover board is swingable to be installed on axis pin.
As a preferred solution, the switching device includes cover board and axis pin, and the axis pin is parallelly mounted to passage
On the divider wall of top, the cover board is swingable to be installed on axis pin.
As a preferred solution, the smoke sensor device for being used for detecting smokescope in tunnel is equipped with the tunnel,
Smoke sensor device is opened making divider wall extend downwardly tank and is unfolded by control device control baffle, and control wind turbine is past
Gas is filled with divider wall and seals up tunnel.
As a preferred solution, the driving device is telescope motor, the piston rod of the telescope motor with it is described
Baffle connects and drives baffle is horizontal to slide.
As a preferred solution, the baffle is installed on the inner wall in the tunnel by the way that axis pin is swingable, described
The output terminal of driving device is connected with baffle and drives swung.
As a preferred solution, the control device is PLC or microcontroller.
As a preferred solution, the divider wall is fire-resistant rubber material.
Implement the present invention, have the advantages that：
1st, divider wall of the invention is folded and is accommodated in tank.When a fire, divider wall extends downwardly simultaneously quilt
Inject gas and expand, seal tunnel until divider wall is full of the cross section in tunnel, to stop that the intensity of a fire and smog are spread, together
When can reduce from the extraneous amount of oxygen for entering fire section, control the burning and sprawling of the intensity of a fire, help to stamp out a fire.Fire is flutterred
After going out, by discharging the gas in divider wall, it is folded again and is recovered in tank, so as to achieve the purpose that recycling.
When in cross section of the divider wall full of tunnel, tunnel is sealed, vehicle and escape personnel can be made from passage by opening switching device
Emergency escape so that while fire is controlled, protection staff can be smooth and rapidly escapes.
2nd, the fire-resistant rubber material that divider wall of the invention uses has the characteristics that frivolous, flexible and elastic, thus every
From wall from tank stretch out during, if escape personnel is isolated wall and pounds, will not escape damaged to personnel completely, have
There are more preferable safety in utilization and reliability, solve after fire generation existing fire resisting shutter and fire resisting shield from tunnel edge
The problem of personnel of vehicle and escape are easily pounded during stretching, cause secondary injury.
3rd, the present invention can promote cover board to be swung toward both sides, make lid after being expanded after divider wall is filled by support shaft of axis pin
Plate staggers and opens passage, so that vehicle and escape personnel's disengaging.And cover board can be reversely promoted at any time and close passage
Close, tunnel is sealed, to stop that the intensity of a fire and smog are spread, while can reduce from the extraneous amount of oxygen for entering fire section, control
The burning and sprawling of the intensity of a fire processed.
4th, the present invention in tunnel by setting smoke sensor device to be detected in real time to smokescope, to judge whether to send out
Light a fire calamity.When detecting that fire occurs, control device control baffle, which is opened, makes divider wall extend downwardly tank and be unfolded, and
Control wind turbine seals up tunnel toward gas is filled with divider wall, and whole process is operated without human hand, is carried by detecting in real time
High reaction and processing speed to fire, have the characteristics that automatic detection control, be quick on the draw with it is easy to use.
