The concrete technical scheme that problem is adopted is as follows：
Movable smoke hangs down wall, including top board, flexible smoke-proof pendant wall, base plate and hot fuse element, described flexible smoke-proof pendant wall two
End is individually fixed on top board and base plate, and flexible with the distance change of two boards；Arrange between described top board and base plate
Finite place piece, for limiting the displacement that base plate occurs distance increase relative to top board；Described locating part includes generation of being heated
The hot fuse element of fusing, and hot fuse element is used for restriction of the elimination locating part to base plate in fusing.
In the present invention, flexible smoke-proof pendant wall is referred to non-rigid stratiform facility, such as Flameproof cloth, fire resisting made by incombustible material
Fiber cloth etc..Hot fuse element referred to when local environment temperature changes, and can make feedback by modes such as expansion, fusings
Structure, it reaches after uniform temperature can fuse at certain position.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 in itself to
The process of few two halves absolute construction.
The operation principle of the technical scheme is：Under the regular situation without fire, top board is fixed on the furred ceiling of building
Or the position such as floor slab bottoms, locating part two ends connect respectively top board and base plate, its relative displacement in vertical direction are carried out
Limit, base plate is fallen；And flexible smoke-proof pendant wall is then laminated or crimp shrinkage is between two pieces of panels.When generation fire
When, there is the fusing phenomenon such as fracture, melting, broken after temperature reaches certain value in the change of the disconnected element senses of hot melt to temperature,
Make to play the constraint that the part for limiting base plate vertical displacement departs from top board on locating part, base plate falls under gravity, while
Flexible smoke-proof pendant wall is driven to stretch, forming one piece can stop the smoke-proof pendant wall that fire hazard aerosol fog horizontal direction spreads.
But the technical scheme is only a most basic scheme of the present invention, it is also based on the program and various shapes is provided
The preferred embodiment of formula, describes 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 base plate, therefore it at least needs
Cover locating part to provide constraints at least one section at position, the section can be cross section, or oblique section.It is spacing
Depending on part provides constraints position according to the form of locating part, such as when locating part is directly connected to bottom for drag-line or connecting rod etc.
During the element of plate, a certain section of the alternative element of hot fuse element；When locating part be by inverted T-type structure, inverted Y-shaped structure or
With the part of contacts baseplate it is directly that this is spacing in these structures when person other increasingly complex structures carry out spacing to base plate
Part provides constraints position, therefore a certain section of replaceable these parts of hot fuse element or directly makes into whole locating part
Hot fuse element.Certainly, it is contemplated that sometimes span can be larger for smoke-proof pendant wall, thus only 1 hot fuse element it is possible that
Cannot accurate, timely temperature sensor problem, it may be considered that multiple heat are equably set on locating part provides constraints position
Fuse element, any hot fuse element occurs fusing can cause falling for base plate.
Preferably, described locating part is two ropes, and one end of two ropes is both secured on top board, the other end
After being each passed through the both sides of base plate, the two ends of hot fuse element are individually fixed in below base plate, are formed to the spacing of base plate.Should
Set-up mode is a kind of preferred implementation of locating part, when there is fire, because hot fuse element is located at the lower section of base plate,
The change of temperature can directly, be delicately sensed, after temperature is higher than certain limit, hot fuse element ruptures, and it two
The fixed rope in end loses restriction, it is impossible to plays the support to base plate and acts on, therefore base plate falls downwards, hangs down so as to form gear cigarette
Wall.And, multiple hot fuse elements can be as needed connected on rope, it is adaptable to the larger applied field of smoke-proof pendant wall span
Close.And the cost of rope is very low, be conducive to saving cost.
As another kind preferably, described locating part is at least 1 fix bar, and fix bar one end is fixed on top board, separately
One end penetrates the through hole opened up in advance on base plate, and it stretches out described through hole one end and is fixed with hot fuse element, the disconnected unit of hot melt
At least one marginal end portion is located at outside through hole drop shadow spread in the horizontal plane in part, but the fuse part of hot fuse element
Position is located within the drop shadow spread.Hot fuse element directly and contacts baseplate, serves the restriction to base plate in the set-up mode
Effect.Under the structure, when hot fuse element fuses, base plate is no longer influenced by constraint, directly falls.
Preferably movable smoke hangs down the control device that be additionally provided with wall as another kind of, described control device include electromagnet,
Spring, ferromagnetism plug and self-resetting switch；In annular shape, electromagnet one end is fixed, and the other end leads at described fix bar top

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
(low melting point alloy, is solid-state and more hard during normal temperature, when temperature reaches specified temp, is closed for material, such as fusible alloy
Golden melt material), or even the corresponding construction controlled by temperature detect switch (TDS) etc..But preferred mode is using fusible alloy or hollow
Thermal expansion material is filled with closed glass tube, and the cavity of the glass tube (material of volumetric expansion can occur after being heated).
Its advantage is that have certain intensity, can bear appropriate pressure or pulling force, but can sensitively make glass tube quick-fried when being heated
Split, release the position-limiting action to base plate.
The shape of above-mentioned glass tube further can be formed by connecting preferably using taper or by the frustum of two speculars
Shape.Because the fusing of glass tube is increased by the volume of pipe thermal expansion material, glass tube is applied from inside to outside
Pressure and it is caused, therefore often there is broken and continuous phenomenon in glass tube.Locating part is especially applicable to using rope
When in scheme, if glass tube yet suffers from adhesion, rope still exists to the support force of base plate, when causing fire to occur, keeps off cigarette
Vertical wall cannot smoothly put down.And pass through test and show, the glass tube of taper, by internal force when can successfully fragmentation be two
Half.The structure that the frustum of two speculars is formed by connecting is also that in the same manner, it is in stress, and tapered diameter section pressure-bearing is larger, is held
Connecting portion easily in two frustums produces the Decrepitation Phenomena for covering whole cross section.In design, can be by the glass of connecting portion
Glass thickness of pipe wall arranges thinner, with further reinforcing fusing herein.Certainly, wall thickness can not be excessively thin, needs to consider it
The mechanical property of itself can undertake the load of base plate.
Another object of the present invention is to provide a kind of smog stop of the wall that hangs down using the movable smoke with control device
Method, its step is as follows：
Top board is fixed on into building interior target location, base plate is by the position-limiting action of fix bar and hot fuse element in receipts
The state of rising, flexible smoke-proof pendant wall is shunk between top board and base plate；During original state, electromagnet is not powered on, and ferromagnetism plug exists
During fix bar top annulus is peaked under the pressure of spring, limit fix bar motion in vertical direction, self-resetting switch is pressed
Button is pressed, positioned at the smoke-proof pendant wall opening indicator lamp power-off of fire protection control center；When a fire, it is disconnected by hot melt
The volumetric expansion of thermo-sensitive material or fusing in element is raised to temperature and makes feedback, and after temperature is increased to certain value, hot melt is disconnected
Element fuses, and base plate displacement in vertical direction is limited and released, and drives flexible smoke-proof pendant wall to fall under gravity
Under, the smog that fire is produced is stopped；Meanwhile, the button of self-resetting switch is upspring, and is connected smoke-proof pendant wall opening and is referred to
Show the power supply circuits of lamp, for fire protection control center alarm of fire is provided；After fire terminates and smog dissipates, base plate is received again
Play and change hot fuse element carries out spacing to base plate, restPoses；When fire protection control center detects the condition of a fire, by fire-fighting
Control centre actively connects magnet spool the two poles of the earth contact makes electromagnet access external power source, and to ferromagnetism plug magnetic is produced
Power, makes ferromagnetism plug end depart from fix bar top annulus, and the displacement in vertical direction of base plate and fix bar is limited and obtained
Release, and drive flexible smoke-proof pendant wall to fall under gravity, the smog that fire is produced is stopped.
Technical scheme in terms of existing technologies, possesses one or more in following beneficial effect：
