Installation and debugging stage points for attention of the present invention:After this electronic and manual integral vent window installation, most
Main debugging efforts, exactly reach a travel switch 7.3 and close the charged signal of travel switch 7.5 in place, corresponding electric window-opening
Device 3 opens, stops relation.The given position of signal, it can finely tune chute 7.2 by reaching a stroke and close stroke in place and finely tune chute
7.4 adjust the given position for reaching a travel switch 7.3, closing the signal of travel switch 7.5 in place respectively, after the completion of position adjustment,
Using stroke locking nut 7.6 respectively reaching a travel switch 7.3, the pass locked and fixed of travel switch 7.5 in place.
The specific control process of the present invention is as follows:
Electric opening process:Needed during granary storage in storehouse divulge information when, it is necessary to open the vent window of silo.At this moment
Wait and give electric window-opening device 3 positive energization, the positive operation of electric window-opening device 3, the telescopic arm 4 of electric window-opening device 3 gradually stretches out drive
Active force rotary part 6 is rotated clockwise running, and passive swingle 12 is driven simultaneously by slidably cross locker 8
Turn clockwise operation, and turning clockwise for passive swingle 12 pulls curved arm rod rear-guard arm 13, curved arm rod forerunner arm 14,
Make the slip dead bolt 15.1 of spring slide lock 15 by the pulling of curved arm rod forerunner arm 14, due to latching locked roller 16.1
With the active force of lock locked and fixed device 16.2, the pulling of curved arm rod forerunner arm 14 makes the slip dead bolt of spring slide lock 15
15.1, strength is acted on latch spring 15.5 and compresses latch spring 15.5, makes slip dead bolt 15.1 from lock locking device
Smoothly depart from 16 so as to unlock, in the presence of dead bolt chute 15.3, lock fixed jacket chute 15.4, pass through granary window
The effect of hinge 18 makes silo window 17 outwards open.When silo window 17 fully opens, a travel switch 7.3 is reached with electrician
Make, cut off the power supply of dynamic window opener 3, dynamic window opener 3 is stopped, and the at this time unlatching of vent window is fully completed, and silo is smooth
Start normal ventilation operation.
Electronic closing process:It is anti-to electric window-opening device 3 when silo ventilation is completed or other reasonses need to close vent window
To energization, the inverted running of electric window-opening device 3, the telescopic arm 4 of electric window-opening device 3, which gradually retracts, drives active force rotary part 6 inverse
Clockwise rotating operation, driving passive swingle 12 by slidably cross locker 8, rotate counterclockwise is run simultaneously.Quilt
The rotate counterclockwise of dynamic swingle 12 promotes curved arm rod rear-guard arm 13, curved arm rod forerunner arm 14, passes through curved arm rod forerunner
The promotion of arm 14 makes spring slide latch 15, begins to shut off silo window 17 by the effect of granary window hinge 18.Work as silo
When window 17 will close, slide dead bolt 15.1 and touch the locked roller 16.1 of lock, the strength of closing passes through dead bolt chute 15.3
Act on latch spring 15.5 and compress latch spring 15.5, shrink slip dead bolt 15.1, it is complete when sliding dead bolt 15.1
Into at the space latched under locked roller 16.1, dead bolt 15.1 automatic spring, lock under the effect of latch spring 15.5 are slided
Locked roller 16.1 and the locked slip dead bolt 15.1 of the can of locked and fixed device 16.2, so as to the silo window of locked closing in place
17, the live line work of travel switch 7.5 in place is simultaneously closed, cuts off the reverse power supply power supply of dynamic window opener 3, dynamic window opener 3 stops
Only work, at this time the closing process of vent window is fully completed, vent window safety shutdown.To prevent from sliding the abjection lock of dead bolt 15.1
Fixed jacket 15.2 is detained, having installed lock anti-drop device 15.6 additional in the afterbody for sliding dead bolt 15.1 is protected.
Hand switch window operates:When electric device break down or other cause specifics existing for need manual open and close grain
During the vent window of storehouse, it is only necessary to lift upper longitudinal locking bar 8.3 of slidably cross locker 8 manually, make lower horizontal locking bar 8.1 de-
From the U-shaped chute 6.1 of lock on active force rotary part 6, active force rotary part 6 and passive swingle can be thus untied
12 connection, allow passive swingle 12 to be in free movement state, can now operate manual window opening handle 10, to be opened,
Close the operation of vent window.Slidably cross lock 8 can still be recovered manually after normal, carry out locked active force rotary part
6 and the connection of passive swingle 12, recover the normal electric operating of row.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technique according to the invention scheme is done
The technology deformation gone out, each falls within protection scope of the present invention.
