[0040] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which may each refer to one or more of the same or different embodiments according to the present application.

[0041] An embodiment of the present application provides a warning device for a rigid fire curtain, as Figure 1 shown, which is applied to a rigid fire curtain. The rigid fire curtain includes a curtain body 100, a mounting frame 110 provided on a stage surface, and a driving device 120.

[0042] Specifically, when a fire accident occurs in a theater or at the end of each performance, the warning device 200 is activated while the rigid fire curtain descends, prompting the staff and audience that the curtain body 100 is descending, informing the relevant staff to pay attention to safety, and protecting the safety of personnel and the safe operation of the rigid fire curtain.

[0043] The driving device 120 of the rigid fire curtain includes an electric lifting device and a manual release device. Under normal circumstances, the rigid fire curtain is controlled to rise and fall by the electric lifting device, and the rigid fire curtain can also be released and lowered by the manual release device.

[0044] As Figures 2 - 4 shown, the warning device 200 includes a housing 210, a baffle 220, a stop frame 221, a detection component, a reminder component, and a controller 230. Among them, the components inside the housing 210 adopt a modular design and are integrated in the housing 210, so that the structure of the warning device 200 is reasonably arranged and compact.

[0045] The housing 210 is connected to the curtain body 100, and a sound outlet hole 2101 is opened on the housing 210. Among them, the sound outlet hole 2101 can be opened on the top surface of the housing 210 and / or the side surface away from the curtain body 100.

[0046] The baffle 220 is resetably arranged on the housing 210 for closing the sound outlet hole 2101. Specifically, a groove is formed on the housing 210, a spring 2102 is arranged in the groove, and the spring 2102 is connected to the baffle 220. The spring 2102 can be arranged on the top surface of the housing 210 and / or the side surface away from the curtain body 100.

[0047] Wherein, the baffle 220 has an inverted L-shaped structure, and a sealing layer is arranged on one side of the baffle 220 close to the housing 210. When the warning device 200 is not in use, dust and sundries are prevented from entering the housing 210 through the baffle 220.

[0048] Both the housing 210 and the baffle 220 are made of fireproof materials, which improves the fireproof performance of the warning device 200 and ensures the integrity and functionality of the device in high-temperature environments such as fires.

[0049] The stop frame 221 is connected to the mounting frame 110. When the curtain body 100 is retracted, the stop frame 221 hinders the movement of the baffle 220, so that the baffle 220 closes the sound outlet hole 2101 after approaching the housing 210. Wherein, the structure of the stop frame 221 is adapted to the structure of the baffle 220.

[0050] In addition, the lower end of the stop frame 221 has an arc-shaped structure, and one end of the baffle 220 close to the stop frame 221 has an arc-shaped structure, so that the baffle 220 can smoothly move to the inside of the stop frame 221.

[0051] The detection component is arranged on the housing 210 for detecting the state of the curtain body 100 and / or the stage surface. Specifically, the detection component includes a laser rangefinder 240 and / or a proximity switch 241.

[0052] The laser rangefinder 240 is arranged on the bottom surface of the housing 210 for detecting the distance between the curtain body 100 and the stage surface. When the rigid fireproof curtain acts, the laser rangefinder 240 measures the distance between the bottom of the curtain body 100 and the stage surface in real time, and inputs the collected data into the controller 230. The laser rangefinder 240 adopts infrared laser measurement technology.

[0053] The proximity switch 241 is arranged on the side wall of the housing 210 for detecting the action of the curtain body 100. The proximity switch 241 adopts a Hall proximity switch. Specifically, when the rigid fireproof curtain acts, an action signal is sent to the proximity switch 241, and the proximity switch 241 is turned on, so that other modules of the warning device 200 start to work, and the emergency conversion time of the warning device 200 is not greater than 0.25 s.

[0054] The reminder component is disposed within the housing 210 and is used to issue a reminder. Specifically, the reminder component includes a voice reminder and / or an optical reminder.

[0055] The voice reminder is disposed within the housing 210 and is used to issue a voice reminder, such as a buzzer 250 and a voice broadcaster 251. Among them, when the rigid fire curtain operates, the buzzer 250 continuously emits a warning sound. The buzzer 250 uses a high-decibel but non-ear-piercing warning sound. And when the curtain body 100 descends to a certain position from the stage surface, the voice broadcaster 251 is turned on to play the distance between the curtain body 100 and the stage surface in real time.

[0056] The optical reminder is disposed on the bottom surface of the housing 210 and is used to issue an optical reminder, such as a laser lamp 260. Specifically, when the rigid fire curtain operates, the laser lamp 260 is turned on to present a warning line on the stage surface. When the curtain body 100 descends to a certain position from the stage surface, the laser lamp 260 starts to flash, and as the distance further decreases, the flashing frequency increases.

[0057] The controller 230 is disposed within the housing 210 and is respectively connected to the detection component, the reminder component, and the driving device 120, and is used to control the opening and closing of the reminder component and the driving device 120 according to the detection signal of the detection component.

[0058] Among them, after receiving and analyzing the data detected by the proximity switch 241 and the laser rangefinder 240, the controller 230 controls the operation of components such as the buzzer 250, the voice broadcaster 251, and the laser lamp 260. Through the intelligent management of the controller 230, the linkage with the operation of the curtain body 100 is realized, and the safety and reliability of the use of the fire curtain are improved. The controller 230 uses a single-chip microcomputer.

[0059] The warning device 200 further includes a power supply 270. The power supply 270 is disposed within the housing 210. The power supply 270 is respectively connected to the detection component, the reminder component, and the controller 230, and is used to provide electrical energy. Among them, the power supply 270 uses a large-capacity lithium battery to ensure that the warning device can work for a long time.

[0060] In one embodiment, the warning device 200 further has a fault detection function. When a component within the warning device 200 cannot be used normally, the faulty component sends a fault signal to the controller 230. After receiving the fault signal, the controller 230 controls the voice broadcaster 251 to play a prompt tone.

[0061] For example, when the battery power is insufficient, it can feedback to the controller 230, and the controller 230 controls the voice broadcaster 251 to issue a prompt to remind the staff to charge or replace the battery.

[0062] In summary, the working process of the warning device 200 is as follows:

[0063] The driving device 120 drives the rigid fire curtain to move. When the rigid fire curtain moves, it sends an action signal to the proximity switch 241. After receiving the action signal, the proximity switch 241 is turned on, enabling each component of the warning device 200 to start working. At the same time, when the rigid fire curtain moves, it drives the housing 210 to move, and the movement of the housing 210 drives the baffle 220 away from the stop frame 221. When the baffle 220 is no longer restricted by the stop frame 221, under the action of the spring 2102, it moves away from the housing 210, exposing the sound outlet hole 2101 for subsequent sound propagation.

[0064] After the warning device 200 is started, the controller 230 controls the buzzer 250 to continuously emit a warning sound, and the controller 230 controls the laser lamp 260 to turn on, presenting a warning line on the stage surface.

[0065] When the laser rangefinder 240 detects that the curtain body 100 is 2.5 m away from the stage surface, the laser rangefinder 240 sends a detection signal to the controller 230. The controller 230 controls the voice broadcaster 251 to play the distance between the bottom of the curtain body 100 and the stage surface in real time. At the same time, the laser lamp 260 starts to flash, and as the curtain body 100 further descends, the flashing frequency increases.

[0066] After use, the rigid fire curtain moves in the reverse direction to retract the curtain body 100. The movement of the curtain body 100 drives the housing 210 and the baffle 220 to move until the baffle 220 contacts the stop frame 221 and, under the action of the stop frame 221, moves closer to the housing 210 to close the sound outlet hole 2101. Moreover, during use, the baffle 220 can also protect the housing 210 and the sound outlet hole 2101 from damage by the outside world.

[0067] Among them, when the bottom of the curtain body 100 is 2.5 m away from the stage surface, the descending speed of the curtain body 100 is reduced. When the bottom of the curtain body 100 is 500 mm away from the stage surface, the descending speed of the curtain body 100 is reduced again to avoid injury and impact on the stage surface.

[0068] In one embodiment, a U-shaped frame (not shown in the figure) is provided on one side of the housing 210. The U-shaped frame is clamped to the bottom end of the curtain body 100, and a connecting bolt abutting against the curtain body 100 is provided on the U-shaped frame. The design of the U-shaped frame enables the warning device 200 to be stably fixed on the curtain body 100. The use of the connecting bolt enhances the structural stability, ensuring the synchronism and reliability of the warning device 200 during the movement of the curtain body 100.

[0069] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions within the essence and protection scope of the present application, and such modifications or equivalent substitutions should also be regarded as falling within the protection scope of the present application.
