Principle of operation

All the parts are at initial positions, when a fire disaster occurs, the high temperature causes the first high temperature hot melting module 40 to firstly disconnect the connection with the first roller shutter 14 and the box body 12, so that the first curtain plate 41 is out of the limit and begins to fall down due to the self weight, the first curtain plate 41 drives the first roller 43 to rotate, the second gear 34 which is meshed with the rack 37 and installed on the first roller 43 is at the initial position and is not contacted with the rack 37, the second gear 34 rotates under the condition of no interference until the first curtain plate 41 is contacted with the ground, the rotation of the first roller 43 simultaneously drives the first rotating telescopic pipe 61 to rotate and extend, and the first gear 60 is pushed to be aligned with the gear ring 63 and to be meshed and matched.

If the fire is not great enough, it will block the first shutter 41, and if the fire is great and lasts for a long time, the high temperature will make the second shutter 42 disconnect from the second roller shutter 15 and the box 12 first, so that the second shutter 42 will break away from the limit and begin to fall by its weight.

In the falling process of the second curtain plate 42, the second curtain plate 42 drives the second reel 44 to rotate, the second reel 44 drives the torsion spring 64 to rotate, the torsion spring 64 starts to store energy due to the rotation of the torsion spring 64, the second reel 44 drives the second rotary extension tube 65 to rotate and extend out when rotating, the ejector rod 66 arranged on the second rotary extension tube 65 pushes the fixing block 67 away when the second curtain plate 42 contacts the ground, the mounting sleeve 62 and the gear ring 63 start to rotate under the rotation of the torsion spring 64, the gear ring 63 drives the first gear 60 to rotate, and the first gear 60 drives the first reel 43 to rotate so as to lift the first curtain plate 41 again.

The continuous high temperature can also open the hot melting switch in the first pipeline 35, water flows into the motor housing 31, the blade 32 is pushed to rotate, the blade 32 rotates to drive the transmission shaft 33 to rotate, the transmission shaft 33 drives the mounting disc 38 to rotate, the mounting disc 38 drives the rack 37 to rotate, the rack 37 is meshed with the second gear 34 to drive the second gear 34 to rotate, the first curtain plate 41 is put down again, when the rack 37 rotates over 180 degrees, the first curtain plate 41 just falls to the ground, the torsion spring 64 stores energy again while the second gear 34 rotates, when the rack 37 rotates out of meshing with the second gear 34, the torsion spring 64 drives the mounting sleeve 62 and the gear ring 63 to rotate, and the gear ring 63 drives the first gear 60 to rotate to pull up the first curtain plate 41 again, so that the cycle is repeated.

After passing through the motor housing 31, the water flow flows into the second pipeline 36, flows into the water delivery pipe 20 through the second pipeline 36, firstly passes through the roller shutter cooling nozzle 21, is sprayed onto the first roller shutter 14 and the second roller shutter 15 through the roller shutter cooling nozzle 21 to cool the first roller shutter 14 and the second roller shutter 15, and particularly, when the first roller shutter 14 is repeatedly lifted and falls, the cooling speed is increased, the water flow flows into the rotary nozzle 17 after passing through the roller shutter cooling nozzle 21, and is sprayed out through the part of the rotary nozzle 17 extending out of the box body 12 in a rotating manner to cool fireproof weak places such as door lintels of the door frame, and after the water flow is sprayed out from the rotary nozzle 17, the remaining water flow flows into the door frame cooling nozzle 22 and is sprayed out through the door frame cooling nozzle 22, so that the cooling effect on the first roller shutter 14, the second roller shutter 15 and the door frame is improved.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
