[0002] With the rapid development of modern architecture, the fire safety issues in commercial places are becoming increasingly prominent. As a common fire-fighting equipment, fire-proof rolling shutter doors can effectively isolate the fire and prevent the fire from spreading when a fire occurs, providing valuable time for personnel evacuation and fire rescue. Among them, the "a fire-proof rolling shutter door" disclosed by the authorization announcement number "CN207470047U" has solved the problem that the fire curtain itself has insufficient ability to filter thick smoke, and the sealing between the fire curtain and the track is limited. The thick smoke at the fire scene is very likely to pass through the fire curtain and enter the inner side of the door frame, thereby causing carbon monoxide poisoning to people hiding inside the fire curtain; therefore, this solution still has technical disadvantages such as major safety hazards, but in actual use, fire-proof rolling shutter doors with similar structures still have many defects, such as: the existing rolling shutter door does not have a locking structure at the bottom, and is easily overturned under the negative pressure of the fire scene, so it is necessary to design a fire-proof rolling shutter door for commercial indoor use.

The rolling shutter mechanism 6 also includes a driven wheel 603, a first motor 604 and a driving wheel 605. The main shaft 601 A driven wheel 603 is installed on the other side, and the front end of the driven wheel 603 is connected to the driving wheel 605 through a transmission belt. A first motor 604 is installed on one side of the driving wheel 605. Temperature sensors 3 are installed at both ends of the top box 1, and smoke sensors 2 are installed at both ends of the top box 1 on one side of the temperature sensor 3; wherein the smoke sensor 2 and the temperature sensor 3 are electrically connected to the wireless controller 4 by wires, and the wireless controller 4 is electrically connected to the first motor 604, the second motor 905 and the winding frame 10 by wires respectively;

[0023] Specifically, when in use, the smoke sensor 2 and the temperature sensor 3 are used to simultaneously detect the location of the device, and the detected data is transmitted to the wireless controller 4 for analysis and processing. When the smoke sensor 2 detects smoke, the first motor 604 in the rolling shutter mechanism 6 drives the driving wheel 605 to rotate. During the rotation of the driving wheel 605, the transmission belt is used to drive the driven wheel 603 to rotate, so that the main shaft 601 lowers the protective rolling shutter door 602 to half the height. When the temperature sensor 3 detects that the temperature is too high at the same time, the wireless controller 4 controls the first motor 604 to completely lower the protective rolling shutter door 602, and uses the bottom beam 608 to increase the weight of the protective rolling shutter door 602, thereby completing the protection;

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a floor lock 7 is installed at the bottom of the guide rail 5, a bottom beam 608 extending to the inside of the floor lock 7 is installed at the bottom of the protective rolling shutter door 602, a limiting hole 609 is provided on the surface of the bottom beam 608, an electric push rod 12 is installed on the surface of the floor lock 7, and a plug rod 13 extending to the inside of the limiting hole 609 is installed at the rear end of the electric push rod 12, an underground box 8 is installed on the periphery of the floor lock 7, a caulking mechanism 9 is installed inside the underground box 8, a reeling frame 10 is installed at both ends of the caulking mechanism 9, and a pull wire 11 connected to the bottom beam 608 is installed on the top of the reeling frame 10; wherein, a jack is provided inside the floor lock 7 to meet the extension of the plug rod 13, and a groove adapted to the bottom beam 608 and the push plate 906 is provided inside the floor lock 7;

[0025] Specifically, the buried box 8 and the floor lock 7 are pre-buried in the ground so that the top of the floor lock 7 is flush with the ground. When the device is not in use, the electric push rod 12 is used to retract the insertion rod 13, and the caulking mechanism 9 is used to block the groove opened by the floor lock 7. When the bottom beam 608 falls, the caulking mechanism 9 drops to a certain height. After the bottom beam 608 enters the interior of the floor lock 7, the electric push rod 12 extends the insertion rod 13 again, and the extended insertion rod 13 is inserted into the limiting hole 609 to lock the bottom beam 608. , to prevent the protective rolling shutter door 602 from being overturned under the negative pressure of the fire scene, and to improve the fire prevention effect, the retracting frame 10 rotates synchronously with the first motor 604 after being powered on, and when the first motor 604 lowers the bottom beam 608, the retracting frame 10 retracts the pull wire 11, and when the first motor 604 drives the bottom beam 608 to rise, the retracting frame 10 pays out the pull wire 11, thereby controlling the lifting and lowering of the bottom beam 608, and preventing the bottom beam 608 from getting stuck during the lifting process, thereby improving the protection effect;

[0026] like Figure 1 , Figure 4 and Figure 5 As shown, the caulking mechanism 9 includes a screw 901, a folding frame 902, a second motor 905 and a push plate 906. The screw 901 is installed inside the buried box 8, and the other side of the screw 901 is connected to the second motor 905. The folding frame 902 is slidably installed on the periphery of the screw 901. The periphery of the screw 901 between the folding frames 902 is provided with a bidirectional thread. The top of the folding frame 902 is provided with a push plate 906 extending to the inside of the floor lock 7. The top of the folding frame 902 is in contact with the bottom of the push plate 906, and the inside of the push plate 906 is provided with a hole adapted to the pull wire 11. When in use, the second motor 905 is powered on to drive the screw 901 to rotate. During the rotation of the screw 901, the bidirectional external thread provided on the periphery can drive the folding frame 902 to fold. The folded folding frame 902 pushes the push plate 906 to move upward inside the floor lock 7, so that the top of the push plate 906 is flush with the top surface of the floor lock 7, thereby preventing foreign matter from entering the groove inside the floor lock 7 when not in use. By opening a hole inside the push plate 906 that is compatible with the pull wire 11, it is convenient for users to connect the pull wire 11 to the bottom beam 608;

[0027] like Figure 1 , Figure 4 and Figure 5As shown, the caulking mechanism 9 also includes a support frame 903 and a spring 904. The support frame 903 is installed inside the buried box 8 outside the screw rod 901, and the spring 904 is installed between the top of the support frame 903 and the push plate 906; wherein the top and bottom of the spring 904 are respectively fixedly connected to the push plate 906 and the support frame 903, and the support frame 903 adopts a door-shaped bracket; specifically, the position of the spring 904 is limited by the support frame 903, and the spring 904 can be used to pull the push plate 906 to avoid the situation that the push plate 906 cannot be lowered after rising;

[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the rolling shutter mechanism 6 also includes a motor frame 606 and a bearing seat 607, the motor frame 606 is installed on the top and bottom of the first motor 604, the other side of the motor frame 606 is connected to the top box 1 by bolts, and the outer side of the main shaft 601 and the driven wheel 603 is installed with a bearing seat 607 embedded in the top box 1; wherein, the main shaft 601 and the driven wheel 603 are rotatably connected with the bearing seat 607, and the bearing seat 607 and the top box 1 are fixedly connected; specifically, when in use, the bearing seat 607 is used to limit the position of the main shaft 601 and the driven wheel 603 inside the top box 1 without affecting the rotation of the main shaft 601 and the driven wheel 603, and the motor frame 606 is used to connect the first motor 604 to the top box 1 when in use, so that the power output of the first motor 604 is more stable.

[0029] The working principle of this embodiment is as follows: before use, the underground box 8 and the floor lock 7 are pre-buried in the ground so that the top of the floor lock 7 is flush with the ground. After the second motor 905 in the caulking mechanism 9 is energized, it drives the screw 901 to rotate. During the rotation of the screw 901, the bidirectional external thread provided on the periphery can drive the folding frame 902 to fold. The folded folding frame 902 pushes the push plate 906 to move upward inside the floor lock 7 so that the top of the push plate 906 is flush with the top surface of the floor lock 7. When the device is not in use, the electric push rod 12 is used to retract the insertion rod 13, and the caulking mechanism 9 is used to block the groove opened by the floor lock 7. When in use, the smoke sensor 2 and the temperature sensor 3 are used to simultaneously detect the location of the device, and the detected data is transmitted to the wireless controller 4 for analysis and processing. When the smoke sensor 2 detects smoke, the first motor 604 in the rolling shutter mechanism 6 drives the driving wheel 605 to rotate. During the rotation, the driven wheel 603 is driven by the transmission belt to rotate, so that the main shaft 601 lowers the protective rolling shutter door 602 to half the height. When the temperature sensor 3 detects that the temperature is too high, the wireless controller 4 controls the first motor 604 to lower the protective rolling shutter door 602 completely. When the bottom beam 608 falls, the caulking mechanism 9 drops to a certain height. After the bottom beam 608 enters the interior of the floor lock 7, the electric push rod 12 extends the insertion rod 13 again. After the extended insertion rod 13 is inserted into the limiting hole 609, the bottom beam 608 is locked to prevent the protective rolling shutter door 602 from being overturned under the negative pressure of the fire scene. After the reeling frame 10 is powered on, it rotates synchronously with the first motor 604. When the first motor 604 lowers the bottom beam 608, the reeling frame 10 reels the pull wire 11. When the first motor 604 drives the bottom beam 608 to rise, the reeling frame 10 pays off the pull wire 11 to control the lifting and lowering of the bottom beam 608.
