Abstract
Description
Technical Field
[0001] This invention relates to the field of fire protection technology for steel structure buildings, specifically to a prefabricated, ultra-large space automatic partition gas fire extinguishing system. Background Technology
[0002] A prefabricated synchronous condenser cabin is a steel structure building that is modularly produced in a factory and then assembled on-site for use. The purpose of the prefabricated synchronous condenser cabin is to protect the synchronous condenser (equipment).
[0003] The existing prefabricated cabins have an open interior space. In the event of a fire, high-temperature smoke can spread rapidly and disorderly within the cabin. This not only accelerates the spread of the fire to non-fired areas, but also causes the extinguishing agent to be rapidly diluted in the large space, resulting in a significant decrease in the uniformity of the spray and making it difficult to form an effective extinguishing concentration in the fire source area. Consequently, the extinguishing efficiency is significantly reduced. At the same time, the rapid spread of smoke can damage more delicate electrical equipment inside the cabin, increasing property damage. Furthermore, the unobstructed spread of high-temperature and toxic smoke also increases the difficulty and safety risks of subsequent personnel rescue and equipment repair. Therefore, the prefabricated cabins cannot meet the fire prevention and extinguishing needs of their large spaces.
[0004] To address the aforementioned technical challenges, we designed a prefabricated, ultra-large space automatic partition gas fire suppression system. Summary of the Invention
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.
[0006] The purpose of this invention is to provide an automatic partitioning gas fire extinguishing system for prefabricated cabins with ultra-large spaces. It has the advantages of quickly partitioning the protected area, blocking the spread of smoke, and improving the utilization rate of extinguishing agents and the efficiency of fire extinguishing. It solves the problems of traditional prefabricated cabins without smoke-blocking partition structures, which lead to rapid smoke diffusion and easy spread of fire during a fire, easy dilution of extinguishing agents resulting in low fire extinguishing efficiency, and also cause more equipment damage and increase the difficulty of rescue.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated cabin ultra-large space automatic partition gas fire extinguishing system, including a cabin (1), the top of the front side of the cabin (1) is connected to a first support plate (2) by bolts, the rear side of the first support plate (2) is riveted to a round tube (3), the surface of the round tube (3) is movably sleeved with a roller (4) through a bearing, the inner cavity of the roller (4) is fixedly connected to a first partition plate (5), the inner cavity of the round tube (3) is connected to a drive motor (6) by bolts, the output end of the drive motor (6) is connected to a coupling (7) by bolts, the surface of the roller (4) is wound with a smoke barrier curtain (8), the rear side of the roller (4) is movably connected to a second support plate (9) through a bearing, and the rear side of the second support plate (9) is connected to the top of the rear side of the cabin (1) by bolts.
[0008] Preferably, a rotating shaft (10) is riveted to the right side of the first partition (5), and the front end of the rotating shaft (10) is connected to the coupling (7) by bolts.
[0009] Preferably, the smoke barrier curtain (8) is made of ceramic fiber cloth, and a counterweight (11) is fixedly connected to the bottom of the smoke barrier curtain (8). The bottom of the counterweight (11) is a flat structure design.
[0010] Preferably, a second partition (12) is fixedly connected to the inner cavity of the round tube (3), and a controller (13) is bolted to the front side of the second partition (12). A cable (14) is fixedly connected to the bottom of the controller (13), and the bottom end of the cable (14) passes through the round tube (3) and is fixedly connected to a control button (15).
[0011] Preferably, the rear side of the first support plate (2) and the front side of the second support plate (9) are both connected to a fixing plate (16) by bolts, and the bottom of the fixing plate (16) is connected to a smoke sensor (17) by bolts.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the combined use of a drive motor, coupling, rotating shaft, drum, smoke curtain, and counterweight, enables rapid division of the protected area. In the event of a fire, the smoke curtain can quickly descend, dividing the large space of the prefabricated cabin into independent areas. The ceramic fiber cloth smoke curtain can effectively block the spread of high-temperature smoke and fire, reduce the effective space of the extinguishing agent, prevent its rapid dilution, ensure the formation of an effective extinguishing concentration in the fire source area, significantly improve extinguishing efficiency, and reduce equipment damage.
[0013] 2. The combined use of the controller, cables, control buttons, and smoke sensors in this invention enables dual control of automatic opening and closing, as well as manual operation on-site. Under normal conditions, the smoke sensor monitors the cabin environment in real time. When the smoke concentration reaches a set threshold, it immediately transmits a signal to the controller, which automatically triggers the drive motor to start, completing the descent and closing of the smoke curtain, achieving a rapid response in the early stages of a fire. Simultaneously, the control buttons installed on-site are connected to the controller via cables. In special circumstances or when manual operation is required, staff can directly control the raising and lowering of the smoke curtain by pressing the control buttons. This provides a redundant design for manual emergency operation, enhancing the flexibility and reliability of the system and providing more comprehensive protection for personnel rescue and equipment protection.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Example 1
[0019] Please see Figures 1-6 The prefabricated, ultra-large space automatic partitioned gas fire extinguishing system includes a cabin 1. A first support plate 2 is bolted to the top of the front side of the cabin 1's inner cavity. A circular tube 3 is riveted to the rear side of the first support plate 2. The first support plate 2 provides a stable mounting point for the circular tube 3, ensuring its secure installation within the cabin 1 and preventing positional displacement due to vibration or other factors during subsequent operation. A reel 4 is movably mounted on the surface of the circular tube 3 via bearings. A first partition plate 5 is fixedly connected to the inner cavity of the reel 4. A drive motor 6 is bolted to the drive motor 6, and a coupling 7 is bolted to the output end of the drive motor 6. A smoke curtain 8 is wound around the surface of the drum 4. By setting the smoke curtain 8, the internal space can be quickly divided in case of fire to block the spread of smoke and fire. A second support plate 9 is movably connected to the rear side of the drum 4 through a bearing. The rear side of the second support plate 9 is bolted to the top of the rear side of the inner cavity of the chamber 1. The second support plate 9 cooperates with the first support plate 2 to provide support at both ends of the drum 4 and improve the stability of the drum 4 when it rotates.
[0020] A rotating shaft 10 is riveted to the right side of the first partition 5. The front end of the rotating shaft 10 is connected to the coupling 7 by bolts. By setting the rotating shaft 10 and the coupling 7, the power transmission between the drive motor 6 and the drum 4 is realized, so that the torque of the drive motor 6 can be accurately transmitted to the drum 4, driving the drum 4 to rotate stably, and providing power guarantee for the raising and lowering of the smoke curtain 8.
[0021] The smoke curtain 8 is made of ceramic fiber cloth, which has excellent high temperature resistance, flame retardancy and heat insulation properties. It can maintain structural integrity in high temperature fire environment and effectively block the transfer of smoke and heat. The bottom of the smoke curtain 8 is fixedly connected to a counterweight 11. The bottom of the counterweight 11 is designed to be completely flat. By setting the counterweight 11, the smoke curtain 8 can be made to fall quickly and vertically by gravity, ensuring that the smoke curtain 8 can fit tightly against the bottom of the cabin 1 and improve the sealing and blocking effect. The flat structure design ensures the contact area between the counterweight 11 and the bottom of the cabin 1 and enhances the fit.
[0022] Example 2
[0023] Please see Figure 4 and Figure 5The prefabricated, ultra-large space automatic partition gas fire extinguishing system has a second partition 12 fixedly connected to the inner cavity of the circular tube 3. The front side of the second partition 12 is bolted to the controller 13. By setting the second partition 12, the controller 13 can be provided with an installation position, and the inner cavity of the circular tube 3 can be reasonably divided to avoid interference between the controller 13 and other components. The bottom of the controller 13 is fixedly connected to a cable 14. The bottom end of the cable 14 passes through the circular tube 3 and is fixedly connected to a control button 15. By setting the control button 15, it is easy for staff to manually control the raising and lowering of the smoke curtain 8 on site, improving the flexibility of the system.
[0024] The rear side of the first support plate 2 and the front side of the second support plate 9 are both connected to the fixing plate 16 by bolts. The bottom of the fixing plate 16 is connected to the smoke sensor 17 by bolts. By setting the smoke sensor 17, the smoke concentration in the cabin can be monitored in real time, the fire signal can be captured in time and transmitted to the controller 13, so as to realize the automatic response of the system and provide a guarantee for rapid prevention and control in the early stage of fire.
[0025] In use, the device is installed inside the cabin 1 via the first support plate 2 and the second support plate 9, and the controller 13 is connected to the fire protection system via a cable. The fire protection system can remotely control the falling and rolling of the smoke curtain 8. During daily use, the smoke sensor 17 monitors the smoke situation inside the prefabricated cabin in real time. When a fire occurs inside the cabin and the smoke concentration reaches the set threshold, the smoke sensor 17 transmits the detection signal to the controller 13 via the cable 14. The controller 13 immediately issues a command to start the drive motor 6. The drive motor 6 drives the rotating shaft 10 to rotate via the coupling 7. The rotating shaft 10 drives the drum 4 to rotate. The smoke curtain 8 wrapped on the drum 4 falls rapidly and vertically under the gravity of the counterweight 11 until the counterweight 11 fits against the bottom of the cabin 1, completing the division of the cabin space and blocking the spread of smoke and fire.
[0026] When manual operation is required, the staff can send a control command to the controller 13 by pressing the control button 15. The controller 13 controls the drive motor 6 to operate, so that the smoke curtain 8 falls. After the fire is extinguished, the staff can send a reset command by pressing the control button 15 or the controller 13. The drive motor 6 will reverse and drive the drum 4 to rewind and store the smoke curtain 8.
