Description

Technical Field

[0001] The utility model relates to the technical field of fire prevention barrier equipment, in particular to a vertically lifting fireproof rolling shutter door. Background Art

[0002] The fireproof rolling shutter door plays the same role as a firewall for horizontal fire separation. Generally, it is installed in parts where it is inconvenient to use a firewall for separation, such as: open elevator lobbies, escalators, large business halls of department stores, exhibition halls of exhibition buildings, and parts of buildings with large openings where fireproof doors and windows cannot be used. In construction projects, the fireproof rolling shutter door has been widely used for fire separation.

[0003] For example, the fireproof rolling shutter door with the publication (announcement) number of CN212755222U includes a flexible curtain and a winding mechanism. The winding mechanism includes a main shaft rotatably installed. An unwinding wheel is coaxially and fixedly arranged outside the main shaft. A traction rope is wound inside the unwinding wheel. The free end of the traction rope is fixedly connected to the bottom of the flexible curtain. The end of the main shaft is power-connected to a power mechanism through a gear pair. The power mechanism includes a first transmission shaft and a second transmission shaft. The first transmission shaft and the second transmission shaft are coaxially arranged. Both the first transmission shaft and the second transmission shaft are spline shafts. A spline sleeve is coaxially and cooperatively installed between the first transmission shaft and the second transmission shaft. The spline sleeve can slide along the axial direction. The first transmission shaft is power-connected to the main shaft through a gear pair. The end of the second transmission shaft is power-connected to a motor through a gear pair. This fireproof rolling shutter door uses a flexible curtain, is suitable for a variety of scenarios, and can be used without power input.

[0004] However, according to the working principle proposed by the above patent, the applicant believes that the above device isolates the fire through a flexible curtain. Although the fireproof rolling shutter is made of high-temperature refractory materials, such as fiberglass, high-temperature resistant fabrics, etc., when the fire is too large, the flexible curtain lacks a cooling system and cannot effectively relieve the heat absorption degree of the flexible curtain. These materials may be damaged due to high temperature, resulting in the automatic detachment of the fireproof rolling shutter or the loss of its fireproof function.

[0005] Therefore, a vertically lifting fireproof rolling shutter door is proposed to solve the above problems. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] The following further elaborates on this application in detail Figures 1-5 with reference to the appended drawings.

[0026] An embodiment of the present application discloses a vertically lifting fireproof rolling shutter door, which includes a wall 1 and a rolling shutter door body 2. One side of the wall 1 is fixedly installed with a box 3. One side of the top of the box 3 is fixedly installed with a liquid storage tank 4. The other side of the top of the box 3 is fixedly installed with a water pump 5. One side of the water pump 5 is fixedly installed with a water inlet pipe 6. The bottom of the water pump 5 is fixedly installed with a drain pipe 7. The bottom of the drain pipe 7 is fixedly installed with a nozzle 8. A cavity 9 is opened inside the rolling shutter door body 2.

[0027] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , through the mutual cooperation of the rolling shutter door body 2, the box 3, the liquid storage tank 4, the water pump 5, the nozzle 8, and the cavity 9, the function of increasing the heat resistance of the rolling shutter door is realized. Thus, the coolant can be released to the inner cavity of the rolling shutter door to cool it, reducing the material aging and performance degradation caused by high temperature, thereby increasing the safety of the rolling shutter door and at the same time extending the service life of the rolling shutter door.

[0028] Control handles 10 are fixedly installed on both sides of the wall 1. Guide rails 11 are fixedly installed on both sides of the inner wall of the wall 1. A limiting rod 12 is fixedly installed inside the guide rail 11. Sealing strips 13 are fixedly installed on both sides of the inner wall of the guide rail 11. A ground rail 14 is fixedly installed at the top of the inner wall of the wall 1. A water storage cavity 15 is opened at the top of the ground rail 14.

[0029] Referring to Figure 2 and Figure 5 , through the mutual cooperation of the guide rail 11, the sealing strip 13, the ground rail 14, and the water storage cavity 15, the function of increasing the sealing performance is realized. Thus, it can prevent the smoke from spreading through the gaps when a fire occurs, thereby ensuring that the rolling shutter door body 2 can effectively isolate the fire area.

[0030] A PLC controller 16 is fixedly installed on one side of the inner wall of the box 3. A smoke sensor 17 is fixedly installed on the back of the PLC controller 16. Alarm lights 18 are fixedly installed on both sides of the front of the box 3.

[0031] Referring to Figure 1 and Figure 4 , through the smoke sensor 17, it is convenient to detect the real-time use environment of the device, so as to take timely measures through the PLC controller 16 before the fire spreads. Through the alarm lights 18, it is convenient to quickly attract people's attention when a fire occurs, and at the same time, it can also remind people to pay attention to the falling gap of the rolling shutter door.

[0032] A driving motor 19 is fixedly installed on one side of the inner cavity of the box 3. A driving gear 20 is fixedly installed on one side of the driving motor 19 through a driving shaft.

[0033] Referring to Figure 4, the driving function is achieved through the driving motor 19 and the driving gear 20. Thus, the purpose of automatic operation can be achieved in cooperation with the PLC controller 16, reducing manual intervention and ensuring the timeliness of fire prevention.

[0034] A rotating shaft 21 is movably installed in the middle part of the inner cavity of the box 3. A driven gear 22 is fixedly installed on one side of the surface of the rotating shaft 21, and a chain 23 is movably installed on the surface of the driven gear 22.

[0035] Refer to Figure 4 , the transmission function is achieved through the driven gear 22 and the chain 23. Thus, it can be ensured that the rotating shaft 21 rotates synchronously with the driving motor 19, and further ensure the precise control of the stroke of the rolling door body 2.

[0036] A limiting cylinder 24 is fixedly installed on the surface of the rotating shaft 21, and a connecting piece 25 is movably installed on the surface of the limiting cylinder 24. The connecting piece 25 is fixedly connected to the rolling door body 2.

[0037] Refer to Figure 4 , it is convenient to control the rolling door body 2 through the limiting cylinder 24 and the connecting piece 25, ensuring that the rolling door body 2 stops at the correct position when opening and closing, thus ensuring the normal operation and use of the fireproof rolling door.

[0038] A heat conduction block 26 is fixedly installed at the bottom of the rolling door body 2, and limiting plates 27 are fixedly installed on both sides of the rolling door body 2.

[0039] Refer to Figure 3 , it is convenient to transfer the temperature on the surface of the rolling door body 2 through the heat conduction block 26, ensuring the heat dissipation effect of the rolling door body 2, and further ensuring the high temperature resistance of the rolling door body 2.

[0040] Working principle: When using this device, through the real-time monitoring of the environment by the smoke sensor 17, the smoke threshold is set by the PLC controller 16. When the smoke exceeds the threshold, the alarm lamp 18 generates a flashing light tube. At the same time, the PLC controller 16 starts the drive motor 19. The drive motor 19 drives the chain 23 to rotate through the drive gear 20, drives the driven gear 22 to rotate through the chain 23, drives the rotating shaft 21 to rotate through the driven gear 22, and drives the limit cylinder 24 to rotate through the rotating shaft 21. At this time, the rolling door body 2 descends due to its own weight. During this period, the limit plate 27 cooperates with the limit rod 12 to ensure that the rolling door body 2 descends vertically. When the drive motor 19 rotates the rolling door body 2 to a predetermined threshold, the water pump 5 introduces the coolant through the water inlet pipe 6, releases the coolant to the nozzle 8 through the drain pipe 7, and releases the coolant to the cavity 9 through the nozzle 8 to increase the high-temperature resistance of the rolling door body 2. The additional liquid is carried by the water storage cavity 15, and the temperature on the surface of the rolling door body 2 is released to the water storage cavity 15 through the heat conduction block 26 to further ensure the timely dissipation of the heat of the rolling door body 2. At the same time, a water cavity is provided at the bottom to prevent the smoke from spreading from the bottom of the rolling door body 2, and the smoke is prevented from spreading from the connection between the rolling door body 2 and the guide rail 11 through the sealing strip 13.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
