Therefore, large shielding rooms are gradually becoming practical, but large shielding rooms need to be equipped with large-volume shielding doors that can be opened. Existing shielding doors cannot meet the transportation of large equipment. It is necessary to design a shielding door that can be opened over a large area, and the shielding door also needs to have a certain degree of protection. Utility Model Content

A motor 6 for driving the reel 2 to rotate is installed at one end of the storage box 1. The rolling shutter plate 3 is hinged by a plurality of chain plates hinged in sequence. In order to ensure the fireproof effect of the rolling shutter door, the rolling shutter plate 3 is hollow, and the hollow rolling shutter plate 3 is filled with a ceramic fiber fireproof blanket 14. One end of the rolling shutter plate 3 is connected to the reel 2, and the other end is connected to the seat plate 4. The guide rail 5 is vertically installed at both ends of the storage box 1, and both ends of the rolling shutter plate 3 are placed in the guide rail 5, and Sliding along the guide rail 5, the bottom and top of the guide rail 5 are respectively installed with a horizontally arranged lower beam 7 and an upper beam 8, both ends of the lower beam 7 and the upper beam 8 are fixedly connected to the guide rail 5, and at the same time, a conductive harness needs to be pre-buried when the shielding room is built, and the conductive harness is connected to the guide rail 5, the lower beam 7 and the upper beam 8. A beryllium copper reed 9 connected to the lower beam 7, the upper beam 8 and the guide rail 5 is installed on the rolling shutter plate 3. In order to ensure the electromagnetic shielding effect of the rolling shutter door, the beryllium copper reed 9 on the top of the rolling shutter plate 3 is hinged to the rolling shutter plate 3 through a torsion spring. After the rolling shutter plate 3 is fully extended, the beryllium copper reed 9 is in contact with the upper beam 8, and the rolling shutter plate 3, the lower beam 7, the upper beam 8 and the guide rail 5 are all made of conductive materials.

[0025] In order to improve the high temperature resistance of rolling shutter doors, Figure 2 As shown, a horizontally arranged water spray pipe 10 is installed under the storage box 1, and a water spray hole 11 facing the rolling shutter plate 3 is processed on the water spray pipe 10, the spacing between adjacent water spray holes 11 is 50 mm, and the diameter of the water spray hole 11 is 2 mm. A plug 12 is installed at one end of the water spray pipe 10, and the other end is connected to a solenoid valve 13 connected to the main water supply pipe.

[0026] To prevent smoke from entering the shielded room, Figure 4 As shown, a fireproof expansion seal 15 in contact with the rolling shutter plate 3 is installed in the guide rail 5 .

[0027] In order to facilitate the control of rolling shutter doors, Figure 1 As shown, the storage box 1 is installed with a controller 16 , a temperature-sensing fire detector 17 and a photoelectric smoke fire detector 18 are installed on the controller 16 , and the controller 16 is connected to the motor 6 .

[0028] The method of using the utility model is:

[0029] When constructing a shielding room, a conductive harness is installed in the wall. At the same time, the guide rail 5, the lower beam 7 and the upper beam 8 are formed into a frame and installed in the door opening. During installation, the conductive harness is connected to the guide rail 5, the lower beam 7 and the upper beam 8. The two guide rails 5 and the lower beam 7 can be installed in an embedded manner.

[0030] When the rolling shutter door is normally closed and encounters a fire, the base plate 4 at the bottom of the rolling shutter plate 3 is in contact with the lower beam 7. At this time, the beryllium copper springs 9 around the rolling shutter plate 3 are respectively connected to the guide rail 5, the lower beam 7 and the upper beam 8. The temperature-sensing fire detector 17 and the photoelectric fire detector detect the fire and send a signal to the controller 16. The controller 16 controls the solenoid valve 13 to open. At this time, the water in the main water supply pipe flows to the water spray pipe 10 and flows out through the water spray hole 11 to cool the rolling shutter plate 3. At this time, the fire-proof expansion seal 15 in the guide rail 5 can prevent smoke from entering the shielding room.

[0031] When the rolling shutter door is normally open or encounters a fire, the temperature-sensing fire detector 17 and the photoelectric fire detector detect the fire and send a signal to the controller 16. The controller 16 controls the motor 6 to work and uses the reel 2 to rotate the rolling shutter plate 3 to unfold the rolling shutter plate 3 so that the bottom of the rolling shutter plate 3 contacts the lower beam 7. At this time, the beryllium copper reed 9 on the top of the rolling shutter plate 3 contacts the upper beam 8 under the action of the torsion spring to form an electromagnetic shielding fire barrier. At the same time, the controller 16 controls the solenoid valve 13 to open. At this time, the water in the main water supply pipe flows to the water spray pipe 10, and flows out through the water spray hole 11 to cool the rolling shutter plate 3. At this time, the fire-proof expansion seal 15 in the guide rail 5 can prevent smoke from entering the shielding room.

[0032] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
