Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1
A kind of fire prevention automatic shutter, as it is shown in figure 1, include door curtain 3, cylinder 1 and jacket 4, door curtain 3 one end is fixed on
On cylinder 1 sidewall, on axle that cylinder 1 two ends are extended 1 and axle 2 42, set is fixed with a bearing 43, in jacket 4 respectively
The top of wall is provided with two suspension rods 44, and the two suspension rod 44 is fixing with above-mentioned two bearing 43 to be connected so that cylinder 1 is hung in cylinder
In cover 4, and can rotate in two bearings 43.Axle 2 42 and the rotating shaft 61 of a motor 6 shaft coupling 62 on the right of cylinder 1 connect
Connect.
As in figure 2 it is shown, motor 6 is connected into power supply 71, motor 6 is in parallel with on the closed-loop path of power supply 71 critesistor
72.Under critesistor 72 room temperature, resistance is less, and therefore motor 6 is shorted.So at normal temperatures, in the case of i.e. there is no fire,
Motor 6 will not work.When breaking out of fire, the resistance moment step of critesistor 72 to millions of ohms, so that its place is returned
Road open circuit, motor 6 again accesses circuit and starts working, and motor 6 drives door curtain 3 to decline, and reaches the effect of automatic fire prevention.Because it is hot
Therefore and critesistor under quick resistance 72 room temperature, resistance is less, prevents power supply 71 short circuit current excessive in the case of short circuit,
72 one conventional, electric-resistance 73 of series connection are as protection.
As shown in Figure 3, Figure 4, rope 1 and rope 2 92 one simple stopping means of composition, rope one 91 one end are fixed on rolling
Barrel cover 4 rear wall, the other end is fixed on axle 1, and rope 2 92 one end are fixed on jacket 4 antetheca, and the other end is also secured at axle one
On 41.When door curtain 3 is all lowered into ground, rope 1 is all wrapped on axle 1 and tight, and rope 2 92 is slack and undisciplined；Door curtain 3 is complete
When portion takes in jacket 4, rope 1 is slack and undisciplined, and rope 2 92 is all wrapped on axle 1 and tight.Such design ensure that door
Curtain 3 will not be drawn into jacket 4 because of excessively rotating of cylinder 1, and rope 1 and rope 2 92 all use fire proofing material to make, will not be by
High temperature roastingization.Door curtain is made up of flameproof fabric, and flameproof fabric is coated with inorfil, instead of the Metallic curtain for door of heaviness, tool
There is outstanding fire protecting performance.
As it is shown in figure 5, be cased with drawing bead chain 2 on the axle 1 on the left side, axle 1 is provided with the hemispherical coordinated with drawing bead chain 2
Groove 5, drawing bead chain 2 is continuous print round chain, and its bottom is enclosed within a pulley fixed on the ground 81, and pulley 81 sets
There is a sheath 82, in sheath 82, be provided with anti-slip rubber 83.The setting of anti-slip rubber 83 is to increase and the frictional force of drawing bead chain 2,
Prevent that door curtain 3 is overweight makes cylinder 1 invert.
Embodiment 2
As shown in Figure 6, as different from Example 1, drawing bead chain 2 one end is enclosed within axle 1, and the other end is enclosed within and is fixed on
On the pulley 81 of wall.Pulley 81 is provided with bearing 84, is fixed on wall by bearing 84 by screw, and level altitude can be according to drawing
Depending on the physical length of pelletron 2.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
