Referring to fig. 1, fig. 2 and fig. 3, the water spraying mechanism 10 includes fixed plate 101, distributive pipe 102 and sprinkler bead 103, 1 top of frame is inlayed and is fixed with fixed plate 101, fixed plate 101 upper surface is fixed with distributive pipe 102, distributive pipe 102 bottom equidistance is fixed with sprinkler bead 103, drenches through water spraying mechanism 10 in to frame 1, can cool down frame 1, the protection motor to prevent that hand wheel 89 from scalding the hand, the people's manual drive of being convenient for.

The invention also provides a use method of the fire damper with high safety, and the use method comprises the following steps:

when the rotary drum 4 is detached, the rotary drum 1 is detachable from the connecting rod mechanism 7, when the rotary drum 4 is detached, people rotate the knob 97 to drive the rotary rod 94 to rotate, so that the rotary rod 94 drives the winding wheel 95 to rotate, the winding wheel 95 winds the two steel wires 96 in the winding wheel 95, the joints of the two steel wires 96 and the winding wheel 95 are arranged in a staggered mode, the two steel wires are prevented from being constantly interfered with each other, the winding wheel 95 winds the steel wires 96 and pulls the rectangular fixture block 91 to move, the rectangular fixture block 91 extrudes the spring 93 and slides out of the connecting cylinder 71, the limit on the rotary drum 4 is released, and the rotary drum 4 is taken down from the rotary rod 94 mechanism;

2. when the rotary drum 4 is installed, firstly, a rotary drum 4 is installed, people rotate the knob 97 in the same step as the step 1 to enable the rectangular fixture block 91 to slide into the inner wall of the rotary drum 4, at the moment, people slide the rotary drum 4 and the gate plate 5 into the space between the two U-shaped frames 3 and toggle the limiting plate 12 on the link mechanism 7 far away from one end of the driving mechanism 8 to enable the limiting plates 12 on the two link mechanisms 7 to be kept at the same angle, and slide the two ends of the gate plate 5 into the space between the two limiting plates 12 at first until the rotary drum 4 moves to the inner wall of the arc-shaped end of the limiting plate 12 to enable the rotary drum 4 to be superposed with the connecting drum 71, at the moment, the rectangular fixture block 91 is inserted into the inner wall of the connecting drum 71 under the elastic force of the spring 93 to complete the installation of the first rotary drum 4, the two link devices are connected through the first rotary drum 4 and the limiting device inside the rotary drum 4 to enable the connecting drums 71 on the link devices to be at the same angle, when the rest of the rotary drums 4 are installed, the installation steps are the same as the steps in sequence, and the difference of the installation steps with the first rotary drum 4 is that the step of shifting the limit plate 12 is reduced;

3. the servo motor 85 is connected with a fire protection control system in the ship, when fire occurs in the ship, the fire protection control system controls the servo motor 85 to rotate, and further drives the worm 84 to rotate, so that the worm 84 drives the worm wheel 82 to rotate, and further drives one connecting shaft 72 on one of the connecting rod devices to rotate, the connecting shaft 72 rotates to drive the U-shaped seat 74 to rotate upwards, and further drives the connecting rod 73 to move upwards through the connecting block 75, so that the connecting rod 73 drives the other six U-shaped seats 74 to turn upwards through the connecting block 75, and further drives the connecting shafts 72 to rotate simultaneously, so that the connecting shaft 72 drives the connecting cylinder 71 to rotate, and further drives the rotary cylinder 4 limited in the connecting cylinder 71 by the limiting mechanism 9 to rotate, so that the rotary cylinder 4 drives the flashboards 5 to turn over, so that the flashboards 5 rotate to a vertical state, and the sealing plates 14 on two adjacent flashboards 5 are mutually clamped, and then seal the space in the frame 1, prevent that the outside air from getting into the space of catching a fire, play the effect of keeping off a fire, and when catching a fire, distributive pipe 102 on the water spray mechanism 10 passes through the water pump with the external water source suction to distributive pipe 102 in, and spray water in to the frame 1 through the shower nozzle, lower the temperature to frame 1, if servo motor 85 breaks down, people pass through rotatory hand wheel 89, and then drive pivot 87 and rotate, make pivot 87 drive the drive bevel gear 88, and then drive driven bevel gear 86 and rotate, make driven bevel gear 86 drive worm 84 and rotate, make people can manual control opening and shutting of flashboard 5, and worm gear has self-locking function, make flashboard 5 after closing, can not open under the effect of gravity, improve its security.
