Abstract
The utility model discloses a smoke control device, and particularly relates to an air supply window mechanical transmission structure for a fire fighting smoke control device. The air supply window mechanical transmission structure for the fire fighting smoke control device is specifically and structurally characterized in that a frame is installed on an outer frame, shaft holes are formed in the frame in the longitudinal direction, a fixing shaft is arranged in each shaft hole, the two ends of the middle portions of blades are movably connected with the frame through the fixing shafts, the two ends of one edge of each blade are connected with a transmission frame through a guide shaft, guide grooves are formed in the transmission frame, the guide shafts are arranged in the guide grooves, and the transmission frame is connected with a rack of a driver through a transmission rod. The air supply window mechanical transmission structure for the fire fighting smoke control device achieves the effect that the blades of a smoke control air supply window can act. The air supply window mechanical transmission structure is installed on an air supply port of an intelligent smoke control system, when the air supply window mechanical transmission structure works, the opening degree of blades at the air supply port can be controlled according to pressure differences sensed by a pressure sensor to control the amount of supplied air, and therefore the effect that the pressure of an escape way area meets the national standard is guaranteed.
Description
Technical field
The utility model relates to a kind of anti-fume extractor, particularly relates to the anti-fume extractor air-supply of a kind of fire-fighting window mechanical transmission structure.
Background technology
The anti-fume extractor air-supply of fire-fighting window is to play the forced draft effect, existing Smoke prevention vent window is the air door that disposable switching is installed at the forced draft ducting outlet, the air door outside is ornamental shutter, shutter is fixed on does not have actual functional capability on the shell, air door is controlled disposable switching by mechanical lock, plays the air-supply effect.This air-supply window is fixed shutter, and air output is non-adjustable.This just causes the air output of some floor big, and the air output of some floor is little, and air output is crossed conference and caused some personages such as old, weak, sick, residual, pregnant door of not opening, and does not have the escape effect, and the little meeting of air output does not have the effect of anti-smoke evacuation.
Summary of the invention
Technical problem to be solved in the utility model provides the anti-fume extractor air-supply of a kind of fire-fighting window mechanical transmission structure, and it is applied in the anti-fume extractor of intelligence, can adjust air quantity, and reliable, flexible, simple in structure, fault is few, maintains easily.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The anti-fume extractor air-supply of fire-fighting window mechanical transmission structure, its concrete structure is as follows: framework is installed on the housing, be vertically arranged with on the framework and be provided with a fixed axis in each axis hole of axis hole, the two ends at blade middle part flexibly connect by fixed axis and framework, the two ends at the edge, one side of blade are connected with gear frame by the axis of guide, offer gathering sill on the gear frame, the axis of guide is arranged in the gathering sill, and gear frame is connected with the tooth bar of driver by drive link.
The structure of above-mentioned driver is as follows: the driving wheel of driven by motor and train of reduction gears engagement, train of reduction gears is connected with tooth bar.
Above-mentioned gathering sill is deep-slotted chip breaker.
Owing to adopt technique scheme, make to the utlity model has following advantage and effect:
The utility model is applied in the anti-fume extractor of intelligence, can adjust air output, has realized the independent regulation of each floor air output.It is reliable, flexible, and is simple in structure, and fault is few, maintains easily.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated, but protection domain of the present utility model is not limit by embodiment.
Shown in Fig. 1-4, the anti-fume extractor air-supply of the utility model fire-fighting window mechanical transmission structure, its concrete structure is as follows: framework 8 is installed on the housing 2, be vertically arranged with axis hole 9 on the framework 8, be provided with a fixed axis 5 in each axis hole 9, the two ends, middle part of blade 3 flexibly connect by fixed axis 5 and framework 8, blade 3 two ends at edge on one side is connected with gear frame 7 by the axis of guide 6, offer gathering sill 10 on the gear frame 7, the axis of guide 6 is arranged in the gathering sill 10, the axis of guide 6 moves along the track of gathering sill 10, and gear frame 7 is connected with the tooth bar 11 of driver 1 by drive link 4.The structure of driver 1 is as follows: the driving wheel 12 of driven by motor and train of reduction gears 13 engagements, train of reduction gears 13 is connected with tooth bar 11, tooth bar 11 is connected with drive link 4, drive link 4 drives gear frame 7 and moves back and forth, gear frame drives the axis of guide by gathering sill and does movement in a curve, thereby drives the blade folding.Gathering sill 10 is deep-slotted chip breaker.
Operating principle of the present utility model is as follows:
The utility model mainly is made up of framework, driver, transmission mechanism and open-and-close mechanism four parts.
Frame part: housing, framework are mainly used to install and fix other parts.
Driver portion: motor, the power resources of whole system; Reducer: formed by gear train; Tooth bar: the circular motion of reducer is converted to rectilinear motion up and down;
The transmission mechanism part: drive link, connect tooth bar and gear frame, conduction drives a pair of gear frame and pumps from the power of driver; Gear frame is installed in the framework left and right sides, and the arc guide groove of constant spacing is arranged above.Drive the axis of guide by the arc guide groove above it, change the folding angle of blade; Gathering sill is arranged in the deep-slotted chip breaker above the gear frame, and gathering sill defines the running orbit of the axis of guide.
Open-and-close mechanism part: blade, air deflector; The axis of guide drives the axle that blade moves along the gathering sill track; Fixed axis is with the axle of vanes fixed on framework.
