Abstract
The utility model discloses a smoke-exhaust resistant device and particularly relates to an intelligent smoke-exhaust resistant device. An output end of a pressure sensor (1) is connected with a control main machine (2), and an output end of the control main machine (2) is connected with a ventilating window opening and closing device (3). The intelligent smoke-exhaust resistant device is installed in staircases and corridors of buildings to perform forced draft so that air pressure in the areas is higher than that of a conflagration area, formation of positive pressure caused by invasion of smoke is avoided, the smoke is squeezed out of the staircases and the corridors, conflagration spreading is controlled, and the pressure can meet the international standard simultaneously. The intelligent smoke-exhaust resistant device can effectively avoid smoke invasion in the corridors and can guarantee that children, the old and the weak can escape from conflagration areas safely.
Description
Technical field
The utility model relates to a kind of anti-fume extractor, particularly relates to the anti-fume extractor of a kind of intelligence.
Background technology
Present domestic skyscraper stands in great numbers, and fire happens occasionally, in case the skyscraper breaking out of fire, smog is to hinder people to escape, carry out action and cause personnel death's one of the main reasons.Modern high-rise civil building; Flammable decoration, furnishings more; The furniture that also has considerable skyscraper to use a large amount of plastics finishings, chemical fibre carpet and filled with foamed plastics; These combustibles can produce a large amount of poison gas and heat in combustion process, will consume a large amount of oxygen simultaneously.Statistics according to the reason that causes casualties in the fire shows; Generally account for the 60%-80% of the total death toll of fire owing to anthracemia death by suffocation or by the smoked the dead of poison gas; And burnt in the middle of the dead people, majority is to poison earlier to suffocate to be scorched to death after falling in a swoon.Therefore, understand and grasp the smog flowing law in the fire of high-rise building, the diffusion of control smog, during fire, in time preventing, discharging fume is important problems in the high building fire fighting security system.
Domestic high-rise all is equipped with the Smoke prevention device at present, because air outlet is simple blinds device, has no intelligence controlling device, can not control air output, so just has some problems to solve.Especially skyscraper, the gas that comes out from blower fan can not evenly discharge, and makes the part floor surpass international standard pressure.And the part floor does not reach international standard pressure, and particularly not can discharge fume in the drawback place of air draft.So just caused another kind of harm.Be pressure when not enough, do not have the Smoke prevention effect.And pressure can make old man, child and weakling can't open door when excessive, hinders and fast and safely evacuates and escape.In other words, maybe be owing to the intelligent inadequately escape chance of having deprived some people of our Smoke prevention device.
The utility model content
The utility model is exactly in order to solve the problems of the technologies described above, and the anti-fume extractor of a kind of intelligence that provides, it can intelligent control air-supply and vent window open and close, reached the effect of anti-smoke evacuation effectively.
In order to solve the problems of the technologies described above, the utility model is realized through following technical proposals:
The anti-fume extractor of intelligence, its structure is following: the output of pressure sensor is connected with main control system, and the output of main control system is connected with the vent window opening and closing device.
Owing to adopt technique scheme, make to the utlity model has following advantage and effect:
The utility model is installed in forced draft in staircase and the corridor in the building; Make this regional air pressure be higher than conflagration area air pressure, prevent that the intrusion of flue gas from forming malleation; Flue gas is squeezed outside staircase and corridor; Spreading of control fire, pressure can also remain within the international standard scope simultaneously.The utility model prevents that effectively smog is invaded in the corridor, can also guarantee children, old weak person's escape unharmed conflagration area.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, pressure sensor; 2, main control system; 3, vent window opening and closing device.
The specific embodiment
Below in conjunction with embodiment the utility model is done and to be described further.Following examples are merely the specific embodiment of the utility model, but the design concept of the utility model is not limited thereto, and allly utilize this design that the utility model is carried out the change of unsubstantiality, all should be within the protection domain of the utility model.
As shown in Figure 1, the anti-fume extractor of the utility model intelligence, its structure is following: the output of pressure sensor 1 is connected with main control system 2, and the output of main control system 2 is connected with vent window opening and closing device 3.
The concrete structure and the operation principle of the utility model are following:
The utility model is mounted in forced draft in staircase and the corridor in the building; Make this regional air pressure be higher than conflagration area air pressure, prevent that the intrusion of flue gas from forming malleation; Flue gas is squeezed outside staircase and corridor; Spreading of control fire, pressure can also remain within the international standard scope simultaneously.According to the size of each floor pressure, show different pressure differences by pressure sensor through display screen, and regulate pressure reduction between 40-60Pa.Maximum differential pressure 60 is defined as below the open required strength 110N of access door, prevents that smog is invaded in the corridor, can also guarantee children, old weak person's escape unharmed conflagration area.
The adjustment of pressure reduction is in time to adjust the drive motors deceleration device by the main control system that can produce driving force according to the data that the pressure sensor collection comes; Convert circular motion to rectilinear motion and adjust control vent window opening and closing device; Switching degree through vent window opening and closing device control vent window blade; The control air output is realized the adjustment of pressure reduction, and the smoke evacuation zone is met international standards with conflagration area pressure reduction.
Claims (1)
1. intelligence is prevented fume extractor, and it is characterized in that structure is following: the output of pressure sensor (1) is connected with main control system (2), and the output of main control system (2) is connected with vent window opening and closing device (3).
