Embodiment 1
Please refer to Fig. 1~3, in the embodiment of the present invention, a kind of intelligent and safe fire resistant doorsets sprayed water, including it is doorframe 1, door-plate 2, double
To screw rod 13, smoke sensor device 19 and travel switch 20；1 two sides of doorframe pass through hinge 3 and are hinged with door-plate 2,2 table of door-plate
Bread is covered with one layer of fire prevention aluminium sheet, and 1 liang of upper lateral part of doorframe is fixedly connected to strut 22, and 22 end of strut is rotatablely connected fixed link
7 ends, 7 other end of fixed link are socketed in loop bar 8, and loop bar 8 is rotatably connected on door-plate 2, it should be noted that in loop bar 8
Spring 9 is installed, spring 9 is in compressive state always, and 9 one end of spring abuts 8 bottom of loop bar, and the other end abuts fixed link 7, benefit
Door-plate 2 is made to be in normally off with spring 9 and fixed link 7 and loop bar 8, when needing to open door-plate 2, spring 9 can be pressed
Contracting, is then automatically closed, flame is effectively avoided to scurry out by the gateway；1 two sides of doorframe are respectively arranged with 10 He of water inlet pipe
Outlet pipe 11, the two are interconnected, row's spray head 18 are equipped with above water inlet pipe 10, is respectively provided on water inlet pipe 10 and outlet pipe 11
There is a solenoid valve 21, the top of water inlet pipe 10 and outlet pipe 11 is fixed on the wall by mounting ring 17, is controlled by solenoid valve 21
The on-off of pipeline, solenoid valve 21 is opened in the case of fire, and aqueous is fed by water inlet pipe 10 and sprayed from spray head 18, plays drop
The effect of flue gas is adsorbed in temperature fire prevention, and extra aqueous is discharged from outlet pipe 11 again, saves water source.
1 upper flange of doorframe is equipped with micromotor 12, and specifically, micromotor 12 is that output end can positive and negative rotation
Servo motor, 12 output end of micromotor are rotatablely connected Bidirectional-screw 13, and Bidirectional-screw 13 is rotatably connected on the top of doorframe 1,
It should be noted that there are two the two sides thread rotary orientation of Bidirectional-screw 13 is symmetrical arranged on the contrary, screw pitch is identical, on Bidirectional-screw 13
Block 14 is covered, set block 14 is threadedly coupled with Bidirectional-screw 13, and set 14 rear portion of block is slidably connected at 1 upper surface of doorframe, works as micromotor
12 will drive the rotation of Bidirectional-screw 13 to which actuating sleeve block 14 is mobile when being powered on, since the rear portion of set block 14 is and doorframe
1 upper surface slide connection, therefore covering block 14 can't follow Bidirectional-screw 13 to rotate；The 14 lower section fixed rotating shaft of set block
15,15 bottom end bearing of shaft connects idler wheel 16, and idler wheel 16 is flushed with the door-plate 2 when being in close state, 13 top of Bidirectional-screw
Center is provided with travel switch 20, and travel switch 20 is fixed on doorframe 1, and 20 signal of travel switch connects solenoid valve 21, normally
Micromotor 12 will not be activated when use state, only can just be activated in the case of fire, and micromotor 12 drives at this time
For the rotation of Bidirectional-screw 13 to drive monosymmetric set block 14 to gather to centre, set block 14 drives the door of the driving of idler wheel 16 two sides
Plate 2 is closed, and when set block 14, which is moved to, to be contacted with travel switch 20, the door-plate 2 of two sides is completely closed, while 20 quilt of travel switch
Triggering, solenoid valve 21 are opened, and aqueous is entered by water inlet pipe 10 and sprayed from spray head 18.
Smoke sensor device 19 is fixedly connected on the door-plate 2,19 signal of smoke sensor device connects micromotor 12, and smog passes
Sensor 19, micromotor 12 and solenoid valve 21 are by wire connecting power and control chip, when smoke sensor device 19 detects
When being more than setting value to smog index, micromotor 12, which is activated and works, realizes the closing of door-plate 2 and the water spray work of water pipe,
The door-plate 2 of closing can prevent fire spreading, the adsorbable smoke fire extinguishing of the aqueous of ejection.
Embodiment 2
In order to which further the above-mentioned intelligent and safe fire resistant doorsets sprayed water are explained, the application provides another embodiment,
The intelligent and safe fire resistant doorsets sprayed water in the embodiment have following technical characteristic: being respectively and fixedly provided on the door-plate 2 of two sides
The handle 6 of opening and closing door-plate 2 is facilitated to be fixed on another side door plate 2 and 4 phase of fixture wherein being fixed with fixture 4 on a side door plate 2
The door lock 5 of adaptation can be closed door-plate 2 by door lock 5 and the cooperation of fixture 4.
According to the specific descriptions of above-described embodiment, being apparent from the working principle of the invention is: using spring 9 and fixed link 7 with
And loop bar 8 makes door-plate 2 be in normally off, when needing to open door-plate 2, spring 9 can be compressed, and be then automatically closed, have
Effect avoids flame from scurrying out by the gateway, and by the on-off of 21 control piper of solenoid valve, solenoid valve 21 is opened in the case of fire,
Aqueous is fed by water inlet pipe 10 and is sprayed from spray head 18, is played the role of cooling fire prevention, is adsorbed flue gas, extra aqueous again from
Outlet pipe 11 is discharged, and saves water source, will drive the rotation of Bidirectional-screw 13 to actuating sleeve when micromotor 12 is powered on
Block 14 is mobile, since the rear portion of set block 14 is to connect with the upper surface slide of doorframe 1, therefore two-way silk can't be followed by covering block 14
Bar 13 rotates, and micromotor 12 will not be activated when normal operating condition, only can just be activated in the case of fire, micro- at this time
Type motor 12 drives the rotation of Bidirectional-screw 13 to drive monosymmetric set block 14 to gather to centre, and set block 14 drives idler wheel 16
The door-plate 2 of two sides is driven to close, when set block 14, which is moved to, to be contacted with travel switch 20, the door-plate 2 of two sides is completely closed, simultaneously
Travel switch 20 is triggered, and solenoid valve 21 is opened, and aqueous is entered by water inlet pipe 10 and sprayed from spray head 18, works as smoke sensor device
19 detect smog index be more than setting value when, micromotor 12, which is activated and works, realizes the closing of door-plate 2 and the spray of water pipe
Water conservancy project is made, and the door-plate 2 of closing can prevent fire spreading, and the adsorbable smoke fire extinguishing of the aqueous of ejection is matched by door lock 5 and fixture 4
Conjunction can close door-plate 2.
It should be noted that micromotor and smoke sensor device are the application of the prior art in the application, passed using smog
Sensor detection smog index and the working condition for controlling micromotor, micromotor work drive Bidirectional-screw rotation to drive
Monosymmetric set block is gathered to centre, and set block drives the door-plate of idler wheel driving two sides to close and trigger travel switch and opens electromagnetism
Valve makes aqueous enter through water inlet pipe and spray from spray head, and the door-plate of closing can prevent fire spreading, and the aqueous of ejection is adsorbable
Smoke fire extinguishing is the innovative point of the application, efficiently solve existing fire resistant doorsets and do not have automatic detection and close door-plate with
And the problem of sprinkling fire.
