Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-4, a portable smoke evacuation fire damper includes a valve body 1, a fan 3, and a base 6 fixedly installed at a lower portion of the valve body 1, wherein louver frames 4 are installed at upper and lower portions of one side of the valve body 1, louver blades 2 are installed between the louver frames 4, a linkage device 41 is installed inside the louver frames 4, the linkage device 41 includes a driving gear 42, a driving rack 43 and a driven gear 46, a motor 5 is embedded at an upper portion of one side of the base 6, an output shaft of the motor 5 is fixedly connected with the driving gear 42, and a return spring 45 is installed at one end of the driving rack 43.
In this embodiment, a through hole for placing the fan 3 is formed inside the valve body 1.
Specifically, this shutter plate 2 is equipped with the multiunit, and rotates with shutter frame 4 and be connected, and this shutter plate 2 adopts fire-proof material, and staggered arrangement between the multiunit shutter plate 2, and closely laminate.
Specifically, the motor 5 is a stepping motor with a temperature control switch, and when the temperature reaches 280 ℃, the power supply of the motor is disconnected, so that the louver blade 2 is closed, and the fire damper is closed.
Specifically, the driving gear 42 is engaged with the driving rack 43 through gear teeth, the driven gears 46 are provided with a plurality of groups and are fixedly connected with the louver blades 2, the driven gears 46 are engaged with the driving rack 43 through the gear teeth, and accurate linkage of all the louver blades 2 is completed through the driving rack 43.
Specifically, the back of the transmission rack 43 is provided with a plurality of sets of magnet pieces 44, and one end of the return spring 45 is fixedly mounted on the inner wall of the louver frame 4.
In this embodiment, when the conflagration breaing out, the fire damper of discharging fume is opened, and fan 3 begins to work, and the louvre piece 2 deflects 90 under the drive of motor 5 this moment, and dense cigarette passes through the fire damper of discharging fume and discharges air pipe, reduces indoor smog concentration, and transmission rack 43 adsorbs at the work position under the effect of magnet strip 44 this moment, overcomes the spring effort, keeps 2 rotation angles of louvre piece.
