TECHNICAL FIELD
[0001] The utility model relates to the technical field of fireproof isolation, more specifically, to a stage rigid fireproof isolation screen. BACKGROUND
[0002] The stage fireproof isolation screen is a critical safety device used to quickly separate the stage area from the audience seating in the event of a fire in theaters, convention centers, and other large performance venues, to prevent the spread of fire and protect the safety of the audience and staff.
[0003] Traditional fireproof isolation screens usually rely on manual or simple electric operation to achieve the lifting of the screen body. However, these methods may have slow response speed, unstable operation, or the inability to quickly start in emergency situations. In addition, due to the complexity of the stage environment, the screen body is easily hindered or out of control during lifting, resulting in equipment damage or safety hazards.
[0004] In recent years, with the increasing demand for safety and technological progress, the design of fireproof isolation screens has gradually developed towards automation and intelligence. By introducing hydraulic damping systems, travel switches, and solenoid valves, the system can quickly respond in the event of a fire and control the precise movement of the screen body. At the same time, the application of counterweight pulleys and balance weight components improves the stability of the screen body movement, reducing the risk of mechanical failure. To further enhance the safety of the system, modern fireproof isolation screens are usually equipped with multiple safety devices, such as anti-tangle devices, overflow valves, and travel detection devices. These devices ensure that the system can operate normally under any conditions and respond promptly in the event of an anomaly, avoiding accidents.
[0005] In summary, the existing technology has the disadvantages of slow response, lack of precise motion control, and lack of safety devices. The new stage fireproof isolation screen improves these problems by integrating various advanced technologies, improving the reliability and safety of the system. SUMMARY
