The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0023] Example 1:
[0024] Please see Figure 1 As shown, this utility model provides a smoke barrier with electronic evacuation and sound indication functions, including a barrier body 1 and an electronic indication unit. A fixing frame 2 is fixedly installed on the top of the barrier body 1. Support springs 3 are fixedly installed on both sides of the inner cavity of the fixing frame 2. A movable plate 4 is installed on the inner end of the support spring 3. A movable block 5 is installed on the inner side of the movable plate 4. A locking seat 6 is engaged with the inner end of the movable block 5. An installation cavity 7 is opened in the interior of both ends of the locking seat 6. The locking end of the movable block 5 is located in the installation cavity 7.
[0025] The electronic indicator unit includes a light source module, a control module, and a display module. The output of the control module is electrically connected to the input of the light source module and the display module, respectively. The output of the control module is also connected to a fire alarm system.
[0026] This technical solution provides clear evacuation guidance to personnel at fire scenes through electronic and audible indicators, enabling them to quickly find their way and reducing the time they spend lost in a chaotic environment, thereby improving evacuation efficiency. During a fire, smoke can severely impair a person's vision and judgment, but the electronic and audible indicators of the smoke curtain are unaffected by smoke and can continuously provide evacuation information, enhancing fire safety. The smoke curtain has a reasonable structural design, simple connection between components, and is easy to install and maintain, making it suitable for various types of buildings.
[0027] Example 2:
[0028] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, the output terminal of the fire alarm system is electrically connected to a voice control module, and the output terminal of the voice control module is electrically connected to a speaker; an upper pressure plate 8 is installed on the upper end of the card holder 6, and connecting posts 9 are fixedly installed on both sides of the top of the upper pressure plate 8. A mounting top plate 10 is fixedly installed on the upper end of the connecting posts 9, and mounting holes 11 are opened on both sides of the top of the mounting top plate 10.
[0029] Adopting such Figure 1 The technical solution shown allows the voice control module to issue clear evacuation instructions via a speaker when a fire alarm signal is received, such as "Please evacuate to the left" or "Please follow the direction of the indicator lights." The speaker has a wide sound propagation range and can cover the entire smoke control zone.
[0030] Secondly, in the technical solution, a positioning frame is fixedly installed at the center of the bottom of the mounting plate 10, and the interior of the positioning frame is connected to the spray pipe 12 through a fixed pipe, and the bent part at the front end of the spray pipe 12 extends to the top of the vertical wall body 1; the light source module adopts high-brightness LED lights, which are evenly distributed on both sides of the vertical wall body 1.
[0031] Its adoption is as follows Figure 1 The technical solution shown, with the top plate 10 connected to the bottom of the spray pipe 12, allows the spray pipe 12 to spray water to extinguish fire or cool down the main body 1 and surrounding area in time when a fire occurs, preventing the fire from spreading and effectively enhancing the fire protection function of the smoke curtain in a fire scenario, thus buying more time for personnel evacuation and fire rescue.
[0032] Example 3:
[0033] This utility model is as follows Figures 1-4 As shown, the wall body 1 is made of fireproof material and is rectangular in shape; the display module is a transparent liquid crystal display screen, which is installed on the front of the wall body 1, and the speaker is installed at the bottom of the back of the wall body 1; guide rods are fixedly installed at both ends of the bottom of the inner cavity of the fixing frame 2, and the upper end of the guide rod is embedded into the interior of the movable plate 4 and slidably installed.
[0034] By adopting the above technical solution, the fireproof material can effectively block the spread of smoke and flames when a fire occurs, buying valuable time for personnel evacuation and fire rescue, and greatly improving the fire safety level inside the building; the upper end of the guide rod is embedded in the movable plate 4 and slidably installed. This design provides stable movement guidance for the movable plate 4, ensuring that the movable plate 4 will not deviate or shake during movement.
[0035] The working principle of this utility model is as follows: When a fire occurs, the fire alarm system sends an alarm signal. After receiving the signal, the control module, as the control center of the entire electronic indicator unit, starts to work. Upon receiving the signal from the control module, the LED lights up, providing clear light indication for the fire scene. At the same time, the control module outputs a signal to the display module, which displays information such as evacuation direction arrows and the location of safety exits according to the instructions of the control module, providing evacuation guidance to personnel in an intuitive visual way. When the fire alarm system sends an alarm signal, the voice control module receives the signal and is activated. According to the preset program, the voice control module emits clear evacuation instruction voice through the speaker, such as "Please evacuate to the left" and "Please follow the direction of the indicator lights to evacuate." When a fire occurs and certain conditions are met (such as temperature or smoke concentration triggering relevant sensors), the fire water supply system connected to the sprinkler pipe 12 is turned on. Water enters the sprinkler pipe 12 through the fixed pipe and then sprays out from the sprinkler pipe 12 to spray water to extinguish the fire or cool the smoke curtain body 1 and the surrounding area, preventing the fire from spreading and protecting the normal function of the smoke curtain and the safety of the surrounding environment.
