[0026] The technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0027] As shown in the drawings: a fire-fighting structure at the stage opening of a venue stage, Figures 1-7

[0028] includes three vertical isolation plates 1 arranged at the interface between the stage and the audience seats (at the stage opening), the isolation plates are divided into several sections according to the height of the stage top from the ground, each isolation plate is suspended at the front end of the stage top by a steel wire rope 2, the steel wire rope is connected to the rear fixed winch equipment 4 on the stage ground through a fixed pulley 3 arranged on the steel beam at the top of the stage, and the lifting of the isolation plate is realized by the driving of the motor. The height of the isolation plate is determined according to the size of the hidden height at the upper part of the stage opening, so that the isolation plates can be hidden after being received to the top, without affecting the normal viewing experience of the audience;

[0029] A sealing device is arranged at the upper and lower parts of each isolation plate to ensure the sealing and smoke prevention between the upper and lower isolation plates. The sealing device is composed of a rigid block 5 fixed at the front end of a flexible fireproof pad 6. When the sealing devices between the isolation plates contact each other when the isolation plates move up and down, the flexible pad can play a role in sealing smoke; when the flexible fireproof pads of the two isolation plates contact each other, the fireproof pad will be deformed by being extruded, but will not be damaged, and the isolation plates between them will not be affected, and can be freely moved up and down, which is convenient for lowering any one of the isolation plates to the stage for maintenance.

[0030] ​A metal water pipe 7 is arranged horizontally along the top of the isolation plate on the side of the audience and the stage, and the diameter of the water pipe is; two rows of branch pipes are arranged uniformly along the water pipe, the water pipe close to the audience side, one row of its branch pipes is opposite the audience (stand) above, and the other row is opposite the isolation plate; the water pipe close to the stage side, one row of its branch pipes is opposite the stage above, and the other row is opposite the isolation plate. The branch pipes opposite the audience and the stage are provided with atomizing water vapor nozzles 8. The water pipe is provided with a booster pump 9, and a high-position water tank 10 is arranged in a concealed part on the top of the stage to supplement water, as an emergency supplement in case of emergency.

[0031] Each hoisting device is connected to an electrical control box 11, is controlled uniformly, and contains a differential control module, so that each isolation plate is started at the same time, stopped at the same time, and the speed is matched during normal work, the travel of each isolation plate is different, but the time of reaching the predetermined position is consistent.

[0032] The isolation plate is a square box body processed from a steel plate (or fireproof plate) with dense mesh holes, and the cavity of the box body is filled with heat-absorbing fire-resistant material 12 to improve the fire resistance time limit of the isolation plate; the control box is connected with a smoke sensing device 13 arranged in the surrounding area of the stage, and once the fire sensor is affected by smoke, the control box is triggered to automatically start the fireproof isolation plate to descend, the water pipe to spray, and other fire isolation actions.

[0033] During use (when a fire occurs), automatic sensing and starting can be used, or manual starting can be used, the isolation plate is quickly (within 50 seconds) lowered from the air through the steel wire rope, a vertical and closed isolation wall is formed at the front of the audience and the stage, the water pipe is also started to spray water and spray, a fireproof water curtain is formed to isolate the fire. Prevents the spread of fire and saves valuable time for personnel evacuation.

[0034] The overall isolation plate of the present application is black in color, and is mainly suspended in a concealed part on the top of the stage opening during normal times, as an emergency use in case of fire. It does not affect the normal use of the daily stage performance.

[0035] When the stage is overhauled, the fireproof isolation plate is lowered, which can be used as a hard closed isolation, and the stage area can be isolated into an independent construction area, so that the construction impact is controlled within a limited area.

[0036] Each hoisting device is connected to an electrical control box, is controlled uniformly, and contains a differential control module, so that each isolation plate is started at the same time, stopped at the same time, and the speed is matched during normal work, the travel of each isolation plate is different, but the time of reaching the predetermined position is consistent.

[0037] The isolation plate is a square box body made of steel plate (or fireproof plate) with dense mesh holes on the surface. The cavity of the box body is filled with heat-absorbing fire-resistant material. When a fire occurs, the temperature of the flame will be transmitted to the heat-absorbing fire-resistant material in the isolation plate through the holes when the flame burns the isolation plate, thereby reducing the heating degree of the outside of the isolation plate and increasing the fire resistance time limit of the isolation plate.

[0038] The control box is connected with the smoke sensing device arranged around the stage area. Once the fire sensing device is affected by smoke, the control box will automatically trigger the fire isolation action such as lowering the fireproof isolation plate and water pipe spraying.

[0039] The height of the isolation plate blocks should consider the time when the isolation plate with the maximum stroke reaches the stage surface to form a closed time that meets the requirements of the fire protection specification.

[0040] By setting a fast-lowering vertical isolation plate between the stage and the audience area, the fire can be quickly isolated when a fire occurs, providing valuable escape time for the audience and performers, and also gaining more space and time for fire rescue work.

[0041] The sealing device arranged between the isolation plates and the atomized water vapor spray head arranged at the top of the isolation plate jointly constitute a strict fireproof isolation system. This system not only prevents the flame from spreading directly to the audience area, but also effectively blocks the spread of smoke, reducing the impact of the fire on the audience area.

[0042] The fire protection structure can be suspended in a hidden place above the stage opening when not in use, without affecting the normal use of the daily stage performance. At the same time, during stage maintenance, the fireproof isolation plate can be used as a hard closed isolation to isolate the stage area into an independent construction area, controlling the impact of construction.

[0043] The structure of the present application is relatively simple, and mature mechanical and electrical control technology is adopted, which is easy to implement and maintain. At the same time, its design concept is suitable for various sizes and types of theaters and venues, and has strong popularization.

[0044] The above is an embodiment provided by the present application and does not limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can modify or replace some technical features of the technical solutions described in the foregoing embodiments, but any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
