The content of the invention
The purpose of one aspect of the present invention is to solve existing active blocking cigarette and hangs down that wall thickness is excessive, cost is too high and can not
Technical problem that is accurate when fire occurs, transferring automatically, and provide a kind of movable smoke vertical wall.The present invention is the solution technology
Concrete technical scheme is as follows used by problem：
Movable smoke hangs down wall, including top plate, flexible smoke-proof pendant wall, bottom plate and hot fuse element, and described flexible gear cigarette hangs down
Wall both ends are individually fixed on top plate and bottom plate, and flexible with the distance change of two boards；Between described top plate and bottom plate
Finite place piece is set, the displacement apart from increase occurs relative to top plate for limiting bottom plate；Described locating part includes heated
The hot fuse element to fuse, and hot fuse element is used to eliminate limitation of the locating part to bottom plate in fusing.
In the present invention, flexible smoke-proof pendant wall refers to use non-rigid stratiform facility made of incombustible material, such as Flameproof cloth, fire resisting
Fiber cloth etc..Hot fuse element refers to when local environment temperature changes, and can make feedback by the mode such as expanding, melting
Structure, it, which reaches, can fuse at certain position after certain temperature.Fusing in the present invention is finger element in certain
After temperature, can by fuse itself or certain a part produce the plane of disruption form make hot fuse element be separated into itself to
The process of few two halves absolute construction.
The operation principle of the technical scheme is：Under the regular situation of no fire, top plate is fixed on the furred ceiling of building
Or the position such as floor slab bottoms, locating part both ends connect top plate and bottom plate respectively, its relative displacement in vertical direction is carried out
Limitation, makes bottom plate not fall；And flexible smoke-proof pendant wall is then laminated or crimp shrinkage is between two pieces of panels.When generation fire
When, change of the disconnected element senses to temperature is heated, the fusing phenomenon such as fracture, melting, broken occurs after temperature reaches certain value,
The part for playing limitation bottom plate vertical displacement on locating part is set to depart from the constraint of top plate, bottom plate falls under gravity, simultaneously
Drive flexible smoke-proof pendant wall to stretch, form one piece of smoke-proof pendant wall that can stop the sprawling of fire hazard aerosol fog horizontal direction.
But the technical scheme is only the most basic scheme of the present invention, it is also based on the program and a variety of shapes is provided
The preferred embodiment of formula, described in detail below for these preferred embodiments.
At least one cross section or oblique at position preferably, described hot fuse element covering locating part provides constraints
Section.When fire occurs, hot fuse element needs to cut off the restriction effect that locating part falls to bottom plate, therefore it at least needs
Covering locating part provides constraints at least one section at position, and the section can be cross section or oblique section.It is spacing
Part provides constraints position depending on the form of locating part, such as when locating part is that drag-line or connecting rod etc. are directly connected to bottom
During the element of plate, a certain section of the hot alternative element of fuse element；When locating part be by inverted T-type structure, inverted Y-shaped structure or
Directly with the part of contacts baseplate it is that this is spacing in these structures when other increasingly complex structures of person carry out spacing to bottom plate
Part provides constraints position, therefore a certain section of these replaceable parts of hot fuse element or directly makes whole locating part into
Hot fuse element.Certainly, it is contemplated that span can be larger sometimes for smoke-proof pendant wall, therefore only 1 hot fuse element it is possible that
Can not accurate, timely temperature sensor the problem of, it may be considered that equably provided constraints in locating part and multiple heat be set on position
Fuse element, fusing, which occurs, for any hot fuse element can cause falling for bottom plate.
Preferably, described locating part is two ropes, and one end of two ropes is both secured on top plate, the other end
After being each passed through the both sides of bottom plate, the both ends of hot fuse element are individually fixed in below bottom plate, are formed to the spacing of bottom plate.Should
Set-up mode is a kind of preferred implementation of locating part, when fire occurs, because hot fuse element is located at the lower section of bottom plate,
The change of temperature can directly, be delicately sensed, after temperature is higher than certain limit, hot fuse element is broken, and it two
The fixed rope in end loses limitation, can not play the supporting role to bottom plate, therefore bottom plate falls downwards, is hung down so as to form gear cigarette
Wall.Moreover, multiple hot fuse elements can be connected on rope as needed, suitable for the applied field that smoke-proof pendant wall span is larger
Close.And the cost of rope is very low, be advantageous to save cost.
As another kind preferably, described locating part is that at least 1 fix bar, fix bar one end are fixed on top plate, separately
One end penetrates the through hole opened up in advance on bottom plate, and it stretches out described through hole one end and is fixed with hot fuse element, heats disconnected member
At least one marginal end portion is located at outside the drop shadow spread of the through hole in the horizontal plane in part, but the fuse part of hot fuse element
Position is within the drop shadow spread.Hot fuse element directly and contacts baseplate, serves the limitation to bottom plate in the set-up mode
Effect.Under the structure, when hot fuse element fuses, bottom plate is no longer influenced by constraint, directly falls.
Preferably movable smoke, which hangs down, is additionally provided with control device in wall as another, described control device include electromagnet,
Spring, ferromagnetism plug and self-resetting switch；Fixed at the top of described fix bar in annular shape, electromagnet one end, the other end leads to
The spring supporting of pretension is crossed on ferromagnetism plug, at the top of the tip insertion fix bar of ferromagnetism plug in annulus, is formed to solid
The activity limitation of fixed pole in vertical direction；In magnet spool the two poles of the earth contact access external power source and by fire protection control center
Control break-make；The supply rings of the smoke-proof pendant wall opening indicator lamp of described self-resetting switch series connection access fire protection control center
Lu Zhong, and the button of controlling switch connecting and disconnecting of the circuit is peaked on bottom plate in self-resetting switch；When bottom plate is in collapsed state, this is pressed
Button is pressed, and circuit is disconnected, and when bottom plate is in full state, the button is upspring, closing of circuit.It is not only real under the preferred embodiment
The vertical wall sensing to temperature of movable smoke is in itself showed, also there is the work(that can receive fire protection control center remote control simultaneously
Energy.Due to being required in existing fire protection rule, the vertical wall of movable smoke needs to have can be by fire protection control center remote control
Function, therefore the improvement project can fully meet standing order.Based on the preferred embodiment, following change can also be further provided for
Enter：
As a kind of further improvement project, described bottom of fixed is fixed limited in hot fuse element top position
Position circle, and the diameter of spacing collar is more than the minimum span of the through hole cross section on bottom plate.When through hole cross section is circular, it is most
Small span is equal to diameter, when through hole cross section is irregular circle, takes the closest distance between two points in its outward flange.Principle
It is that spacing collar can not pass through the through hole in dropping process.
The effect of the spacing collar is：Annulus is unfettered at the top of the fix bar causes bottom plate drop event, and fix bar is not
It can drop, can still be limited in above through hole through the through hole on bottom plate.The function is kept off in fire protection control center remote control
Cigarette hangs down during wall decline, can prevent fix bar from being fallen with the hot fuse element of bottom to ground, in order to avoid hit, injure by a crashing object
Just the personnel to be escaped below smoke-proof pendant wall.Certainly, spacing collar can also use other alternate designs, for example, fix bar with
Static line made of incombustible material is used to connect between top plate, it is thus in any case (including the fusing of hot fuse element), fixed
Bar will not fall.
As another further improvement project, described bottom of fixed is also in annular shape, the disconnected member of described hot melt
Part, which inserts, realizes fixation in the annulus.The structure can be changed easily to hot fuse element, when the disconnected component wear of hot melt
Or when needing to safeguard renewal, a new element can be mounted directly, without changing whole locating part.
In any of the above-described scheme, the structure of hot fuse element can be that by the various elements or material of fuse function
Material, such as fusible alloy (low melting point alloy, are solid-state and more hard during normal temperature, when temperature reaches specified temp, closed
Golden melt material), or even corresponding construction controlled by temperature detect switch (TDS) etc..But preferable mode is using fusible alloy or hollow
Closed glass tube, and filled with thermal expansion material (material that volumetric expansion can occur after heated) in the cavity of the glass tube.
Its advantage is that have certain intensity, can bear appropriate pressure or pulling force, but can sensitively make glass tube quick-fried when heated
Split, release the position-limiting action to bottom plate.
The shape of above-mentioned glass tube can further be formed by connecting preferably using taper or by the frustum of two speculars
Shape.Because the fusing of glass tube is the volume increase by pipe thermal expansion material, glass tube is applied from inside to outside
Caused by pressure, therefore broken and continuous phenomenon often occurs in glass tube.Locating part is especially applicable to using rope
When in scheme, if glass tube still has adhesion, rope still exists to the support force of bottom plate, when causing the fire to occur, keeps off cigarette
Vertical wall can not smoothly be put down.And by experiment show, the glass tube of taper, when by internal force can successfully fragmentation be two
Half.The structure that the frustum of two speculars is formed by connecting is also that similarly, in stress, tapered diameter section pressure-bearing is larger for it, is held
Easily the Decrepitation Phenomena of covering whole cross section is produced in the connecting portion of two frustums., can be by the glass of connecting portion in design
Glass thickness of pipe wall sets thinner, further to strengthen fusing herein.Certainly, wall thickness can not be excessively thin, it is necessary to consider it
The mechanical property of itself can undertake the load of bottom plate.
Another object of the present invention is to provide a kind of smog using the vertical wall of the movable smoke with control device to stop
Method, its step are as follows：
Top plate is fixed on building interior target location, bottom plate passes through at the position-limiting action of fix bar and hot fuse element
In collapsed state, flexible smoke-proof pendant wall is shunk between top plate and bottom plate；During original state, electromagnet is not powered on, and ferromagnetism is inserted
Bolt peaks at the top of fix bar in annulus under the pressure of the spring, the motion of limitation fix bar in vertical direction, self-resetting switch
Button be pressed, positioned at fire protection control center smoke-proof pendant wall opening indicator lamp power off；When a fire, heat is passed through
In fuse element thermo-sensitive material volumetric expansion or fusing feedback is made to temperature rise, it is hot after temperature is increased to certain value
Fuse element is fused, and the displacement of bottom plate in vertical direction, which limits, to be released, and drives flexible gear cigarette to hang down under gravity
Wall is fallen, and smog caused by fire is stopped；Meanwhile the button of self-resetting switch is upspring, smoke-proof pendant wall opening state is connected
The power supply circuit of state indicator lamp, alarm of fire is provided for fire protection control center；After fire terminates and smog dissipates, again the bottom of by
Plate pack up and change hot fuse element to bottom plate carry out it is spacing, restPose；When fire protection control center detects the condition of a fire, by
Fire protection control center, which actively connects magnet spool the two poles of the earth contact, makes electromagnet access external power source, and ferromagnetism plug is produced
Magnetic attraction, ferromagnetism plug end is set to depart from annulus at the top of fix bar, the displacement limitation of bottom plate and fix bar in vertical direction
Released, and drive flexible smoke-proof pendant wall to fall under gravity, smog caused by fire is stopped.
Technical scheme in terms of existing technologies, possesses the one or more in following beneficial effect：
1st, the vertical wall of movable smoke of the invention realizes that slimming (can be controlled within 2cm thickness, or even 1cm thickness also has
May), thoroughly solve the problems, such as that fixed smoke-proof pendant wall, conventional activity smoke-proof pendant wall take furred ceiling lower section or furred ceiling internal height.
2cm thickness, it is also thinner than the thickness of furred ceiling in itself, so height limitation is not present for practical application angle.And bottom
Plate can need to be sprayed into different colors according to finishing, or be made from different materials, suitable for requiring higher to finishing
Occasion.
2nd, it uses hot fuse element to realize the whereabouts of smoke-proof pendant wall, simple in construction, without the electrical equipment or electricity of complexity
Sub- control device, therefore make relatively low with maintenance cost.
3rd, existing fire protection rule requires that the vertical wall of all movable smokes can be opened by telecommunications number, therefore the present invention carries
The technical scheme of control device, be provided simultaneously with meet cigarette automatically fall off, telecommunications number control fall and remote status instruction
Function, therefore the requirement of current specifications can be met well.If control electromagnetism manually is set near smoke-proof pendant wall
The button of iron power supply circuit break-make, the function that local telecommunication number control is fallen can also be realized.
