When the information receiving module receives a fire alarm signal, the indicator module is used to provide indication information prohibiting passage; when the information receiving module does not receive a fire alarm signal, the indicator module is used to provide indication information allowing passage. Since the information receiving module is coupled to the automatic fire alarm controller to receive the fire alarm signal of the area on the other side of the door panel output by the automatic fire alarm controller, the information received by the information receiving module regarding whether a fire has occurred on the other side of the fire door is more accurate.

[0030] In existing technologies, fire alarm indication devices typically only serve to prompt people to evacuate quickly when a fire occurs, or they can only provide safety instructions based on the situation near the fire door. This makes it impossible for people to obtain detailed information about the area on the other side of the fire door during the evacuation process, which makes the evacuation work difficult and is not conducive to the rapid evacuation of people after a fire.

[0031] To address the aforementioned technical problems, this utility model provides a fire door, comprising: a door panel, the door panel including a first side and a second side disposed opposite to each other; a fire alarm indicator device, the fire alarm indicator device including: an indicator module disposed on any side of the door panel, and used to provide indication information as to whether a fire has occurred in an area on the other side of the door panel; and an information receiving module coupled to the indicator module, the information receiving module being coupled to a fire alarm controller to receive a fire alarm signal from the fire alarm controller for the area on the other side of the door panel; wherein, when the information receiving module receives a fire alarm signal, the indicator module is used to provide indication information prohibiting passage, and when the information receiving module does not receive a fire alarm signal, the indicator module is used to provide indication information allowing passage.

[0032] In the scheme disclosed in this utility model, the fire door includes a door panel having a first side and a second side arranged opposite to each other, and a fire alarm indicator device; the fire alarm indicator device includes: an indicator module disposed on either side of the door panel, the indicator module being used to provide indication information as to whether a fire has occurred in the area on the other side of the door panel, and an information receiving module coupled to the indicator module, the information receiving module being used to be coupled to an automatic fire alarm controller to receive a fire alarm signal output by the automatic fire alarm controller for the area on the other side of the door panel; when the information receiving module receives a fire alarm signal, the indicator module is used to provide indication information prohibiting passage; when the information receiving module does not receive a fire alarm signal, the indicator module is used to provide indication information allowing passage. Since the information receiving module is coupled to the automatic fire alarm controller to receive the fire alarm signal of the area on the other side of the door panel output by the automatic fire alarm controller, the information received by the information receiving module regarding whether a fire has occurred on the other side of the fire door is more accurate. Consequently, the indication information provided by the indication module is more accurate, which helps to prevent people from accidentally opening the fire door corresponding to the location of the fire during the evacuation process of a fire accident. This also improves the safety of people during the evacuation process of a fire accident, thereby reducing the risks during the evacuation process and improving evacuation efficiency. Furthermore, when the information receiving module receives a fire alarm signal, the indicator module provides a prohibition instruction; when the information receiving module does not receive a fire alarm signal, the indicator module provides a permission instruction. This allows people to quickly open the corresponding fire door and pass through, or quickly move away from the corresponding fire door and continue searching for other exits, thus improving evacuation efficiency and reducing the risk of people accidentally entering dangerous areas. In summary, the fire door provided by this utility model helps improve the safety and efficiency of personnel evacuation during a fire.

[0033] To make the above-mentioned objectives, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Figure 1 This is a circuit diagram of one embodiment of the fire alarm indicator device of this utility model. Figure 2 This is a perspective view of an embodiment of the fire alarm indicator device of this utility model when a fire alarm signal is received. Figure 3 This is a perspective view of an embodiment of the fire alarm indicator device of this utility model when no fire alarm signal is received.

[0035] refer to Figure 1 and Figure 6In this embodiment, the fire door 200 includes: a door panel 210, the door panel 210 including a first side 211 and a second side 212 disposed opposite to each other; and a fire alarm indicator 100, the fire alarm indicator 100 including: an indicator module 110 disposed on any side of the door panel 210 and used to provide indication information on whether a fire has occurred in the area on the other side of the door panel 210; and an information receiving module 120 coupled to the indicator module 110, the information receiving module 120 being coupled to a fire alarm controller to receive a fire alarm signal from the fire alarm controller outputting a signal from the area on the other side of the door panel 210; wherein, when the information receiving module 120 receives a fire alarm signal, the indicator module 110 is used to provide indication information prohibiting passage (e.g., ...). Figure 2 As shown), when the information receiving module 120 does not receive a fire alarm signal, the indicating module 110 is used to provide indication information allowing passage (such as...). Figure 3 (As shown).

[0036] It should be noted that, in order to clearly show the structure of the fire door, Figure 6 The rescue components in the groove on the second side are omitted.

[0037] In this embodiment, the fire door 200 also includes a door frame (not shown).

[0038] The door frame provides a mounting base for the door panel 210, enabling the door panel 210 to be opened and closed.

[0039] The door panel 210 is used to control the connection and separation between two adjacent areas. The door panel 210 also provides an installation base for the fire alarm indicator 100.

[0040] As an example, the first side 211 and / or the second side 212 of the door panel 210 are used to provide an installation base for setting up the fire alarm indicator device 100.

[0041] It should be noted that the door panel 210 is installed on the inner side of the door frame and is movably connected to the door frame. Specifically, a hinge 201 is installed on the side of the door panel 210 to allow the door panel 210 to be movably connected to the door frame (e.g., Figure 4 and Figure 5 (As shown).

[0042] The indicator module 110 is used to provide indication information as to whether a fire has occurred in the area on the other side of the door panel 210.

[0043] The information receiving module 120 is used to enable the indicating module 110 to provide an indication message prohibiting passage or an indication message allowing passage, depending on whether a fire alarm signal is received.

[0044] Since the information receiving module 120 is coupled to the automatic fire alarm controller to receive the fire alarm signal of the area on the other side of the door panel 210 output by the automatic fire alarm controller, the information received by the information receiving module 120 regarding whether a fire has occurred on the other side of the fire door is more accurate. Consequently, the indication information provided by the indication module 110 is more accurate. That is, the information provided by the fire alarm indication device 100 regarding whether a fire has occurred on the other side of the fire door 200 is more accurate. This helps to prevent people from accidentally opening the fire door 200 corresponding to the location of the fire accident during the evacuation process of a fire accident, thereby improving the safety of people during the evacuation process of a fire accident, reducing the risk during the evacuation process, and improving the evacuation efficiency.

[0045] Furthermore, when the information receiving module 120 receives a fire alarm signal, the instruction module 110 provides an instruction indicating that passage is prohibited. When the information receiving module 120 does not receive a fire alarm signal, the instruction module 110 provides an instruction indicating that passage is permitted. This allows people to quickly open the corresponding fire door 200 and pass through, or quickly move away from the corresponding fire door 200 and continue to look for other exits, thus improving the efficiency of personnel evacuation and reducing the risk of people accidentally entering dangerous areas.

[0046] In summary, the fire alarm indicator 100 provided by this utility model embodiment helps to improve the safety and efficiency of personnel evacuation in the event of a fire.

[0047] In this embodiment, as Figure 4 and Figure 5 As shown, the fire alarm indicator 100 is mounted on the fire door 200, which improves the recognizability of the indicator module 110 of the fire alarm indicator 100. In other embodiments, the fire alarm indicator can also be mounted at other locations in the area to be detected, such as on the wall next to the fire door.

[0048] As an example, such as Figure 4 As shown, there are two fire alarm indicator devices 100, which are respectively installed on the first surface 211 and the second surface 212; wherein, the fire alarm indicator device 100 installed on the first surface 211 is used to receive the fire alarm signal of the area on the second surface 212 output by the automatic fire alarm controller, and the fire alarm indicator device 100 installed on the second surface 212 is used to receive the fire alarm signal of the area on the first surface 211 output by the automatic fire alarm controller.

[0049] As another example, such as Figure 5 As shown, there is one fire alarm indicator 100, which is disposed on any side of the door panel 210. The fire alarm indicator 100 is used to receive a fire alarm signal from the area on the other side of the door panel output by the automatic fire alarm controller. Specifically, the fire alarm indicator 100 is disposed on the first side. It can be understood that the fire alarm indicator 100 can also be disposed on the second side.

[0050] In this embodiment, as Figure 4 and Figure 5 As shown, the indicator module 110 protrudes from the surface of the door panel 210, which helps to improve the recognizability of the indicator module 110, thereby making it easier for people to quickly find the indicator module 110 during evacuation and evacuate according to the indicator information of the indicator module 110.

[0051] In this embodiment, the distance from the center point of the indicator module 110 to the ground is greater than 1.2 meters, which helps to improve the recognizability of the indicator module 110 during evacuation.

[0052] In this embodiment, as Figures 2 to 4 As shown, the indicator module 110 includes a no-entry indicator module 111 and a passage indicator module 112; when the information receiving module 120 receives a fire alarm signal, the no-entry indicator module 111 lights up (e.g., ...). Figure 2 As shown), to provide a prohibition indication; if the information receiving module 120 does not receive a fire alarm signal, the passage indication module 112 lights up (as shown). Figure 3 (As shown), to provide indication information that passage is permitted.

[0053] Specifically, the prohibition indicator module 111 and the passage indicator module 112 are arranged side by side, that is, the prohibition indicator module 111 and the passage indicator module 112 are arranged in a row, which is beneficial to increase the size of the prohibition indicator module 111 and the passage indicator module 112, thereby improving the recognizability of the indicator module 110 during the evacuation process.

[0054] In this embodiment, both the prohibition indicator module 111 and the passage indicator module 112 include a protective cover 113 (e.g., Figures 2 to 4 (as shown), and a light source 114 disposed in the protective cover 113 (as shown). Figure 1 As shown in the figure, the light source 114 is a point light source or an extended light source.

[0055] The light source 114 is used to illuminate the indicator module 110.

[0056] The protective cover 113 is used to protect the light source 114 in order to extend the service life of the light source 114.

[0057] As an example, such as Figure 2 and Figure 3 As shown, when the light source 114 is an extended light source, the protective cover 113 is a light-transmitting protective cover, the shape of the light-transmitting protective cover of the prohibition indicator module 111 is “×”, and the shape of the light-transmitting protective cover of the passage indicator module 112 is “↑”.

[0058] The light source 114 and protective cover 113 of the prohibition indicator module 111 are used together to form an "×" prohibition sign to indicate that passage is prohibited. The light source 114 and protective cover 113 of the passage indicator module 112 are used together to form an "↑" passage sign to indicate that passage is permitted.

[0059] It is understood that the prohibition instruction is indicated by the shape of the protective cover 113 of the prohibition instruction module 111 and the corresponding light source 114. The permission instruction is indicated by the shape of the protective cover 113 of the passage instruction module 112 and the corresponding light source 114.

[0060] In other words, the number of light sources 114 in each of the indicator modules 110 can be one or more, so that the brightness of each of the indicator modules 110 can be adjusted according to the actual situation.

[0061] As another example, when the light source is a point light source, the protective cover is a transparent protective cover, the point light sources of the no-entry indicator module are closely arranged to form an "×" no-entry sign, and the point light sources of the passage indicator module 112 are closely arranged to form an "↑" passage sign;

[0062] It is understood that both the prohibition indicator module 111 and the passage indicator module 112 have multiple point light sources. The prohibition indication is achieved by arranging the point light sources of the prohibition indicator module 111 into a specific shape. The passage permission indication is achieved by arranging the point light sources of the passage indicator module 112 into a specific shape.

[0063] If one of the multiple point light sources that make up a prohibition sign or a pass sign is damaged, it will not easily affect the overall display effect of the prohibition sign or the pass sign.

[0064] Moreover, the "×" and "↑" shapes clearly and concisely convey the meanings of "no passage" and "passage permitted." Therefore, using the "×" shape as a prohibition sign and the "↑" shape as a passage sign allows people to quickly and accurately receive the instructions during evacuation.

[0065] In one embodiment, both the prohibition indicator module 111 and the passage indicator module 112 include a light source 114. The light source 114 of the prohibition indicator module 111 is a red light source, and the light source 114 of the passage indicator module 112 is a green light source.

[0066] The light source 114 of the no-entry indicator module 111 is a red light source, which is used to make the no-entry indicator module 111 appear red when it is lit, that is, the no-entry indicator module 111 is red.

[0067] The light source 114 of the passage indicator module 112 is a green light source, which is used to make the passage indicator module 112 appear green when it is lit, that is, the passage indicator module 112 is green.

[0068] Red indicates no passage and green indicates passage is permitted. This is a widely adopted design scheme that allows people to receive instructions quickly and accurately during evacuation.

[0069] In this embodiment, the indicator module 110 includes indicator lights.

[0070] Indicator lights are inexpensive, which helps reduce the cost of the indicator module 110. In other embodiments, the indicator module may also include an indicator screen.

[0071] In this embodiment, the fire alarm indicator 100 further includes a power supply 140 (e.g., Figure 1 (As shown).

[0072] The power supply 140 provides electrical energy to illuminate the indicator module 110, providing indication information as to whether a fire has occurred.

[0073] Specifically, the light source 114 of the indicator module 110 is used to convert the electrical energy into light energy.

[0074] In this embodiment, as Figure 1 As shown, the information receiving module 120 includes a relay 121. The terminals of the coil 122 of the relay 121 are coupled to the automatic fire alarm controller to receive the fire alarm signal from the area on the other side of the fire door 200 output by the automatic fire alarm controller. The common terminal 123 of the relay 121, the normally open terminal 124 of the relay 121, the prohibition indicator module 111, and the power supply 140 are connected in series in a normally open circuit. The common terminal 123 of the relay 121, the normally closed terminal 125 of the relay 121, the passage indicator module 112, and the power supply 140 are connected in series in a normally closed circuit. This simplifies the structure of the information receiving module 120 and helps to reduce the cost of the information receiving module 120.

[0075] Specifically, when the relay 121 receives a fire alarm signal, the coil 122 of the relay 121 is energized, thereby closing the normally open terminal 124 of the relay 121 and opening the normally closed terminal 125 of the relay 121, which in turn causes the prohibition indicator module 111 to light up; when the relay 121 does not receive a fire alarm signal, the coil 122 of the relay 121 is de-energized, thereby closing the normally closed terminal 125 of the relay 121 and opening the normally open terminal 124 of the relay 121, which in turn causes the passage indicator module 112 to light up.

[0076] In this embodiment, the door panel 210 further includes: a groove 215 (such as...). Figure 6 As shown), the groove 215 is located within any surface of the door panel 210, i.e., within one or both of the first surface 211 and the second surface 212. When the groove 215 is located within the first surface 211 and the second surface 212, the groove 215 of the first surface 211 and the groove 215 of the second surface 212 are isolated from each other, so that the area on the first surface 211 side of the fire door 200 is isolated from the area on the second surface 212 side of the fire door 200, thereby avoiding affecting the fireproof effect of the fire door 200; rescue component 220, the rescue component 220 includes: rescue rope 221, which is disposed in the groove 215, and one end of the rescue rope 221 has a fixed positional relationship with the groove 215.

[0077] The groove 215 is used to receive the rescue rope 221.

[0078] The rescue rope 221 is used to enable rescuers to quickly return to the position of the fire door 200 according to the guidance of the rescue rope 221.

[0079] Specifically, the rescue component 220 further includes: a winding reel 222, which is rotatably disposed in the groove 215; the rescue rope 221 is wound around the winding reel 222, and one end of the rescue rope 221 is fixedly connected to the winding reel 222, so that one end of the rescue rope 221 has a fixed positional relationship with the groove 215.

[0080] The rescue rope 221 is wound around the winding reel 222, which facilitates the rapid release of the rescue rope 221. Moreover, the winding of the rescue rope 221 around the winding reel 222 also helps to improve the neatness of storing the rescue rope 221.

[0081] More specifically, the rescue component 220 also includes a handle 223, which is fixedly disposed on the surface of the winding reel 222 exposed by the surface of the door panel 210.

[0082] The handle 223 is used to improve the convenience of storing the rescue rope 221 so that the rescue rope 221 can be quickly rewound onto the winding reel 222 after use.

[0083] In this embodiment, the other end of the rescue rope 221 is provided with a buckle (not shown), which facilitates the quick connection of the rescue rope 221 to the fire suit, or facilitates the quick tying of the rescue rope 221 around the waist of the rescuer.

[0084] As an example, the fasteners include hooks, carabiners, etc.

[0085] In this embodiment, the length of the rescue rope 221 is 1.5 to 2 times the furthest rescue distance; wherein, the furthest rescue distance is the distance from the door panel 210 to the furthest point in the area corresponding to the rescue rope 221.

[0086] The length of the rescue rope 221 is greater than or equal to 1.5 times the maximum rescue distance, which makes it easier for rescuers to reach any point in the area corresponding to the rescue rope 221 even in situations where semiconductor equipment is densely packed. The length of the rescue rope 221 is less than or equal to 2 times the maximum rescue distance, which reduces the difficulty of storing the rescue rope 221 in the groove 215.

[0087] Accordingly, this utility model also provides a fire alarm device. Figure 7 This is a functional block diagram of an embodiment of the fire alarm device of this utility model.

[0088] refer to Figure 7 and in conjunction with references Figures 1 to 6 In this embodiment, the fire alarm device includes: a fire detector 400, which is installed in the area to be detected and detects whether a fire has occurred in the area; a fire door 200 as described in any embodiment of the present invention, corresponding to the area where the fire detector 400 is located; and an automatic fire alarm controller 500, which is coupled to both the fire detector 400 and the fire alarm indicator 100, and is used to receive the fire alarm signal emitted by the fire detector 400 and transmit the fire alarm signal to the corresponding information receiving module 120.

[0089] In this embodiment, the fire detector 400 is used to detect whether a fire has occurred in the area. When fire information is detected, the fire detector 400 is used to transmit the fire alarm signal to the automatic fire alarm controller 500 in the form of an electrical signal.

[0090] It should be noted that the fire detector 400 includes a smoke detector 401, a temperature detector 402, etc. The smoke detector 401 is used to obtain fire information by detecting smoke. The temperature detector 402 is used to obtain fire information by detecting temperature.

[0091] In the fire alarm device provided in this embodiment of the utility model, since the information receiving module 120 is coupled to the automatic fire alarm controller to receive the fire alarm signal of the area on the other side of the door panel 210 output by the automatic fire alarm controller, the information receiving module 120 receives information on whether a fire has occurred on the other side of the fire door. Consequently, the indication information provided by the indication module 110 is more accurate. That is, the information on whether a fire has occurred on the other side of the fire door 200 provided by the fire alarm indication device 100 is more accurate. This helps to prevent people from accidentally opening the fire door 200 corresponding to the location of the fire accident during the evacuation process of a fire accident, thereby improving the safety of people during the evacuation process of a fire accident, reducing the risk during the evacuation process, and improving the evacuation efficiency.

[0092] Furthermore, when the information receiving module 120 receives a fire alarm signal, the instruction module 110 provides an instruction indicating that passage is prohibited. When the information receiving module 120 does not receive a fire alarm signal, the instruction module 110 provides an instruction indicating that passage is permitted. This allows people to quickly open the corresponding fire door 200 and pass through, or quickly move away from the corresponding fire door 200 and continue to look for other exits, thus improving the efficiency of personnel evacuation and reducing the risk of people accidentally entering dangerous areas.

[0093] In summary, the fire alarm indicator 100 provided by this utility model embodiment helps to improve the safety and efficiency of personnel evacuation in the event of a fire.

[0094] It should be noted that for a detailed description of the fire door, please refer to the detailed description of the foregoing embodiments, which will not be repeated in this embodiment.

[0095] Although the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
