The utility model relates to a rationally, convenient to use, it is as the equipment that installs additional of ground iron winds pavilion temporarily, can effectively solve the conflagration operating mode flue gas short circuit problem that iron winds pavilion exhaust fire smoke spreads and invade subway new trend pavilion and ground access & exit by a large scale of going to the fields.
Description
Technical field
The utility model is related to technical field of fire control, and in particular to be that a kind of universal ground iron winds booth flue gas short circuit is filled
Put.
Background technology
Wind booth is the port that subway station and running tunnel and the external world carry out air exchange, be subway ventilation air-conditioning system not
The part that can lack.As subway line and the ground auxiliary building at station, must set 3 near each segment or station～
8 wind booths.At present, in Practical Project, it be all " air-supply booth-smoke exhaust and ventilation booth-piston that most of wind booth puts in order
Wind booth ", and the spatial depiction difference of wind booth is built according to obtained by ground, each wind booth can set up separately and can also build jointly.
However, due to ground space anxiety, and the requirement of each subway station supply and exhaust amount is different, thus wind booth many sizes,
Do not fix, wind booth size as shown in the table and spacing：
When there is fire, if wind booth size is larger, closer to the distance between wind booth, and air draft booth flue gas velocity is relatively low
(about 4m/s), then when discharging fume by wind booth, be susceptible to phenomenon (the flue gas appearance that i.e. certain air draft booth is discharged of flue gas short circuit
Easily large area spreads, and invades subway station again via adjacent wind booth and ground gateway), cause flue gas to be difficult to by effectively
Discharge, cause station smoke exhaust efficiency low, and pollute evacuating personnel and the rescue passage that goes out, thus materially increase fire
Calamity danger and fire fighting and rescue difficulty.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of universal ground iron winds booth, is particularly suited for
The flue gas short-circuiting means of the high open short wind booths of 1m, it is used as the interim additional equipment of ground iron winds booth, it is possible to resolve under fire working
The problem that iron winds booth can not effectively discharge fume.
For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of universal ground iron winds booth flue gas short-circuiting means, stretches comprising outlet flue, flameproof fabric, the first of at least four
Heat-Shrinkable Tubings and be at least by quantity second telescopic tube of four, spring and support column are constituted for wind booth exhaust outlet
The cuboid connection framework of Matching installation；Described first telescopic tube one end is fixed therein on a support column, and the other end is then
It is connected to outlet flue；The flameproof fabric is arranged on the interior volume being made up of the first telescopic tube and cuboid connection framework, with
First telescopic tube, cuboid connection framework and outlet flue collectively form discharge flue, induce what is discharged via wind booth exhaust outlet
Flue gas orientation is discharged.
Preferably, first telescopic tube is square telescopic tube.
Preferably, second telescopic tube is circular telescopic tube.
Preferably, the flameproof fabric is made up of PTFE glass fibre class membrane materials.
Compared with prior art, the utility model has the advantages that：
(1) the utility model simple structure, design ingenious, distinct characteristics, easy to use.
(2) by arranging multiple telescopic tubes, spring and support post, constituting one can freely convert the utility model
Angle, the solid space structure of shapes and sizes, then after outlet flue and flameproof fabric is coordinated, when there is fire working, can
Quickly, accurately realize being flexibly matched with subway station wind booth exhaust outlet, optimize the air current composition of air draft booth discharge flue gas, effectively
The generation of flue gas short circuit phenomenon is avoided, while realize the smooth discharge of flue gas, is the safe escape of trapped personnel and is disappeared
Anti- personnel implement fire fighting and rescue and provide favourable condition, and then have ensured indicator of trapped personnel in subway station, fire fighting and rescue as far as possible
Fireman and the safety of installations and facilities.
(3) practice have shown that, after installing the utility model additional temporarily on ground iron winds booth, the flue gas stream after the utility model
More than scooter 10m/s, and plume tissue is orderly, thus the orientation quick drain of underground fire hazard flue gas is realized well.
(4) the utility model can not only solve ground iron winds booth flue gas short circuit problem, and versatility is very strong, by each
The stretching of telescopic tube and spring, can flexible adaptation various sizes of ground iron winds booth exhaust outlet installation, therefore, this practicality
It is new to be highly suitable as subway fire fighting and rescue equipment and subway station security against fire safeguard large-scale promotion application under battle conditions.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 removes the structural representation after flameproof fabric for the utility model.
Wherein, reference is corresponding entitled：
1- outlet flues, 2- flameproof fabrics, the telescopic tubes of 3- first, the telescopic tubes of 4- second, 5- springs, 6- support columns.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with embodiment for explanation, and mode of the present utility model includes
But it is not limited only to following examples.
As shown in Figure 1, 2, the utility model provides a kind of ground iron winds booth flue gas short-circuiting means, it include outlet flue 1,
Flameproof fabric 2, the first telescopic tube 3, the second telescopic tube 4, spring 5 and support column 6.First telescopic tube 3 at least provided with
Four, and one end of all of first telescopic tube is all connected on outlet flue 1；Second telescopic tube 4, the and of spring 5
