Fire escape indicating device

Abstract

This invention discloses a fire escape indicator device. The rear end of a housing is mounted to a wall. The housing has a downward-facing cavity containing two accommodating channels extending vertically and spaced apart horizontally. A display frame is positioned below the housing, close to the ground, and has upward-facing slots that connect to the cavity. A display window is located on the front side of the display frame. Two fluorescent indicator signs are inserted into the two accommodating channels, each with a directional marking on its front side. Each fluorescent indicator sign descends along its corresponding accommodating channel to be inserted into its slot, exposing its marking in the display window. The two markings indicate opposite directions. Because the display frame is close to the ground, escaping personnel bending forward can clearly see the markings in the display window, quickly determining their escape route and thus increasing their escape success rate.

Description

Technical Field

[0001] This invention relates to the field of fire emergency equipment technology, specifically to a fire escape indicator device. Background Technology

[0002] Airports, rail transit systems, tunnels, passenger hubs, hospitals, schools, stadiums, exhibition halls, star-rated hotels, and high-end commercial buildings typically have multiple emergency evacuation signs to guide people to safe passages in the event of a fire. As a fire progresses, the dense smoke obstructs the vision of those escaping. Furthermore, as the fire intensifies and the smoke concentration rises, harmful gases and smoke rise upwards. To avoid inhaling the smoke, evacuees must stoop to move forward. Since emergency evacuation signs are usually positioned relatively high, and the smoke concentration gradually increases from the ground upwards, evacuees' vision becomes blurred, making it difficult to identify escape routes and reducing the probability of a successful escape. Summary of the Invention

[0003] The main objective of this invention is to propose a fire escape guidance device, which aims to solve the problem that it is difficult for people escaping from a fire to obtain escape directions through emergency evacuation signs.

[0004] To achieve the above objectives, the present invention provides a fire escape indicator device, comprising:

[0005] A receiving shell, the rear end of which is used to be installed to a wall, the receiving shell having a downward-facing cavity, and two receiving channels extending vertically and spaced apart in the front-back direction are formed in the cavity.

[0006] A display frame is located below the receiving shell and close to the ground. The display frame has an upward-facing slot that connects to the receiving cavity. A display window is provided on the front side of the display frame.

[0007] Two fluorescent indicator signs are respectively inserted into the two receiving channels, and each sign has an indicator on its front side. The indicator is used to indicate direction. Each fluorescent indicator sign can fall down along the corresponding receiving channel to be inserted into the slot and the indicator is exposed in the display window. The two indicator signs are arranged in opposite directions.

[0008] Optionally, the upper surfaces of both fluorescent signs are provided with protrusions, and the sides of the two protrusions facing each other are provided with receiving grooves.

[0009] The fire escape indicator also includes a mounting mechanism, which comprises:

[0010] The mounting assembly has two mounting portions arranged at an angle, each of which extends into one of the receiving slots; and...

[0011] A drive motor is disposed within the cavity and connected to the upper wall of the cavity. The drive motor is located above the accommodating channel. The output shaft of the drive motor extends vertically and drives and connects the two mounting parts.

[0012] Of the two mounting parts, one of the mounting parts is driven to disengage from the corresponding receiving slot, so that the corresponding fluorescent indicator sign falls down.

[0013] Optionally, the fire escape indicator further includes a camera and a smoke detector, both of which are located above the housing and electrically connected to the drive motor.

[0014] Optionally, each of the fluorescent indicator signs includes:

[0015] A transparent plastic shell forming a sealed cavity, the sealed cavity being filled with peroxide;

[0016] A glass tube, disposed on the rear side wall of the sealed cavity, with both ends sealed, is filled with an ester compound. If the glass tube breaks under external force, the ester compound within its cavity can mix with the peroxide within the sealed cavity to produce light; and...

[0017] A label plate is disposed on the front side wall of the sealed cavity, and part of the label plate is hollowed out to form the label section.

[0018] Optionally, the rear side of the display frame is provided with a striking hole and a through hole, the striking hole and the through hole being spaced apart vertically and opposite to each other;

[0019] The fire escape indicator also includes a striking mechanism, which comprises:

[0020] The striking assembly includes a torsion spring, a connecting rod, and a striking part. The torsion spring is installed on the rear side of the display frame and extends in the left-right direction. The torsion spring is located above the striking hole and is opposite to the striking hole. The upper end of the connecting rod is connected to the torsion arm of the torsion spring, and the lower end is bent toward the display frame to form an installation section. The striking part is located at the end of the installation section.

[0021] A support plate, located within the slot and movable vertically, supports the fluorescent indicator sign. A portion of the support plate passes through the through-hole and extends beyond the display frame to form a mounting end. A mounting post protrudes from the upper surface of the mounting end.

[0022] A shielding block is provided on the upper end face of the mounting column and located between the display frame and the striking part to shield the striking hole. The rear side of the shielding block is provided with a groove to fit the end of the striking part.

[0023] Optionally, a guide tube is provided between the housing and the display panel. The guide tube extends vertically, and its two openings in the vertical direction are respectively connected to the cavity opening and the slot opening. The rear side of the guide tube is inclined from top to bottom toward the display frame.

[0024] Optionally, the fire escape indicator device further includes an emergency indicator light, which is installed above the housing.

[0025] Optionally, the fire escape indicator further includes a scattering mechanism, the scattering mechanism comprising:

[0026] The mounting box is located on the upper end face of the housing. The mounting box has an air inlet on one side facing left and right to allow the cavity of the mounting box to communicate with the outside. The mounting box has an air outlet on the front side.

[0027] A fan, disposed inside the mounting box, with its air inlet facing the air inlet; and,

[0028] An air duct is installed inside the mounting box and connected to the air outlet to guide the air blown out by the fan to the air outlet.

[0029] The emergency indicator light is located outside the mounting box and on the front side of the mounting box. The emergency indicator light and the air outlet are arranged side by side in the left and right direction.

[0030] Optionally, the upper surface of the mounting box is provided with two lighting lamps, which are spaced apart in the left-right direction.

[0031] Optionally, the display frame has at least one support block on the side facing the wall, and the support block is located near the lower end of the display frame to abut against the wall.

[0032] In the technical solution of the present invention, the fire escape indicator device includes a housing, a display frame, and two fluorescent indicator signs. The rear end of the housing is used to install it onto a wall. The housing has a cavity with an opening facing downwards. Two housing channels are formed in the cavity, extending vertically and spaced apart horizontally. The display frame is located below the housing and close to the ground. The display frame has an slot with an opening facing upwards, which can correspondingly communicate with the cavity. A display window is provided on the front side of the display frame. The two fluorescent indicator signs are respectively inserted into the two housing channels, and their front sides are provided with marking portions. The marking portions are used to indicate directions. Each fluorescent indicator sign can fall down along the corresponding housing channel to be inserted into the slot, and the marking portion is exposed in the display window. The indicating directions on the two marking portions are arranged in opposite directions. In the event of a fire, the escape direction is determined based on the actual situation, and the fluorescent indicator sign, pointing in the same direction as the escape, is lowered to be inserted into the slot. The fluorescent indicator sign then falls into the display frame near the ground, with its markings visible through the display window to guide escape routes for evacuees. Because the display frame is positioned close to the ground, evacuees bending over can clearly see the markings in the display window, allowing them to quickly determine their escape route and thus increasing their chances of survival.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] Airports, rail transit systems, tunnels, passenger hubs, hospitals, schools, stadiums, exhibition halls, star-rated hotels, and high-end commercial buildings typically have multiple emergency evacuation signs to guide people to safe passages in the event of a fire. As a fire progresses, the dense smoke obstructs the vision of those escaping. Furthermore, as the fire intensifies and the smoke concentration rises, harmful gases and smoke rise upwards. To avoid inhaling the smoke, evacuees must stoop to move forward. Since emergency evacuation signs are usually positioned relatively high, and the smoke concentration gradually increases from the ground upwards, evacuees' vision becomes blurred, making it difficult to identify escape routes and reducing the probability of a successful escape.

[0052] In view of this, the present invention proposes a fire escape indicator device. The display frame is positioned close to the ground, allowing evacuees bending over to clearly see the markings at the display window, enabling them to quickly determine the escape route and thus improving their escape success rate. Figures 1 to 10 The image shows an embodiment of the fire escape indicator device provided by the present invention.

[0053] like Figure 1 and Figure 2As shown, the fire escape indicator device 100 proposed in this invention includes a housing 1, a display frame 2, and two fluorescent indicator signs 3. The rear end of the housing 1 is used to install it to a wall. The housing 1 has a cavity with an opening facing downwards. Two housing channels 11 extending vertically and spaced apart horizontally are formed in the cavity. The display frame 2 is located below the housing 1 and close to the ground. The display frame 2 has an slot with an opening facing upwards, which can correspondingly connect to the cavity. A display window 21 is provided on the front side of the display frame 2. The two fluorescent indicator signs 3 are respectively inserted into the two housing channels 11, and their front sides are provided with marking parts 3a. The marking parts 3a are used to indicate directions. Each fluorescent indicator sign 3 can fall down along the corresponding housing channel 11 to be inserted into the slot, and the marking parts 3a are exposed in the display window 21. The indicating directions on the two marking parts 3a are arranged in opposite directions.

[0054] In the technical solution of the present invention, the fire escape indicator device 100 includes a housing 1, a display frame 2, and two fluorescent indicator signs 3. The rear end of the housing 1 is used to install it to a wall. The housing 1 has a cavity with an opening facing downwards. Two housing channels 11 extending vertically and spaced apart horizontally are formed in the cavity. The display frame 2 is located below the housing 1 and close to the ground. The display frame 2 has an slot with an opening facing upwards. The slot can correspondingly communicate with the cavity. A display window 21 is opened on the front side of the display frame 2. The two fluorescent indicator signs 3 are respectively inserted into the two housing channels 11, and their front sides are provided with marking parts 3a. The marking parts 3a are used to indicate directions. Each fluorescent indicator sign 3 can fall down along the corresponding housing channel 11 to be inserted into the slot, and the marking parts 3a are exposed in the display window 21. The indicating directions on the two marking parts 3a are arranged in opposite directions. In the event of a fire, the escape direction is determined based on the actual situation, and the fluorescent indicator sign 3, which points in the same direction as the escape route, is lowered to be inserted into the slot. Thus, the fluorescent indicator sign 3 falls into the display frame 2 near the ground, with its marking portion 3a exposed in the display window 21, indicating the escape route to escaping personnel. Because the display frame 2 is positioned close to the ground, escaping personnel bending over can clearly see the markings in the display window 21, allowing them to quickly determine the escape route and thus improving their escape success rate.

[0055] By providing a hanging mechanism 4 within the housing 1, the two fluorescent indicator signs 3 are suspended within the two housing channels 11 in the absence of fire, and can fall into the display frame 2 in the event of a fire, serving as an escape direction indicator. Specifically, in this embodiment, as... Figures 2 to 5As shown, the upper surfaces of the two fluorescent indicator signs 3 are each provided with a protrusion 3b, and the two protrusions 3b are recessed into receiving grooves 3c on their respective sides facing each other; the fire escape indicator device 100 also includes a hanging mechanism 4, which includes a hanging component 41 and a drive motor 42. The hanging component 41 has two hanging parts 411 arranged at an angle, and the two hanging parts 411 extend into the two receiving grooves 3c respectively; the drive motor 42 is located in the cavity and connected to the upper wall of the cavity. The drive motor 42 is located above the receiving channel 11, and the output shaft of the drive motor 42 extends vertically and drives the two hanging parts 411; by driving one of the hanging parts 411 to disengage from the corresponding receiving groove 3c, the corresponding fluorescent indicator sign 3 falls. Specifically, the two hanging parts 411 respectively cooperate with the two receiving slots 3c, thereby suspending the two fluorescent indicator signs 3 in the two receiving channels 11. When a fire occurs, the drive motor 42 is turned on, thereby driving one of the hanging parts 411 to detach from the corresponding receiving slot 3c, so that the corresponding fluorescent indicator sign 3 falls into the display frame 2 set near the ground, thus indicating the escape direction for escaping personnel. It should be noted that when a fire occurs, after determining the escape direction according to the actual situation, the drive motor 42 is turned on and its forward and reverse rotation is controlled so that the fluorescent indicator sign 3 indicating the same direction as the escape direction falls.

[0056] Furthermore, in this embodiment, as Figure 1 As shown, the fire escape indicator 100 also includes a camera 5 and a smoke detector 6. Both the camera 5 and the smoke detector 6 are located above the housing 1 and are electrically connected to the drive motor 42. Thus, through the cooperation of the camera 5 and the smoke detector 6, it can be determined whether a fire has occurred. If a fire occurs, the escape route is determined based on the scene captured by the camera 5. Furthermore, the drive motor 42 is activated, causing the fluorescent indicator sign 3, whose direction is the same as the escape direction, to fall.

[0057] It should be noted that the escape route can be determined by the staff in the monitoring room or by the control device based on the information obtained from the fire scene. Specifically, in this embodiment, the camera 5 is an infrared camera 5. In this way, infrared images can be acquired through the camera 5, and the sensitivity and accuracy of fire detection and personnel detection can be ensured by analyzing and comparing the color video images and infrared video images. The smoke detector 6 detects smoke. The housing 1 also contains a controller, a centralized power supply, and a power distribution device. The controller works in conjunction with the fire alarm controller as the main unit. In an emergency, it can quickly analyze the nearest exit, the fire trend, and the crowd density to provide safe evacuation route instructions, thereby controlling the drive motor 42 to make the fluorescent indicator 3, which indicates the same direction as the escape direction, fall.

[0058] In this embodiment, as Figure 3 and Figure 6 As shown, each of the fluorescent indicator signs 3 includes a transparent plastic shell 31, a glass tube 32, and an indicator plate 33. The transparent plastic shell 31 forms a sealed cavity filled with peroxide. The glass tube 32 is located on the rear side wall of the sealed cavity, with both ends sealed. The glass tube 32 is filled with an ester compound. When the glass tube 32 breaks under external force, the ester compound inside its cavity can mix with the peroxide in the sealed cavity to produce light. The indicator plate 33 is located on the front side wall of the sealed cavity, and part of the indicator plate 33 is hollowed out to form the indicator part 3a. Thus, when the glass tube 32 breaks under external force, the ester compound inside the glass tube 32 flows out and reacts with the peroxide in the sealed cavity to produce fluorescence. In this way, it can emit light without power to indicate the escape direction, improving the practicality of the fire escape indicator device 100.

[0059] To break the glass tube 32 that falls into the fluorescent indicator 3 of the display frame 2, a striking structure 7 capable of breaking the glass tube 32 is provided on the rear side of the display frame 2. Specifically, in this embodiment, as shown... Figure 1 , Figure 7 and Figure 8As shown, the rear side of the display frame 2 has a striking hole 22 and a through-hole 23. The striking hole 22 and the through-hole 23 are spaced apart vertically and opposite to each other. The fire escape indicator device 100 also includes a striking structure 7, which includes a striking component 71, a support plate 72, and a blocking block 73. The striking component 71 includes a torsion spring 711, a connecting rod 712, and a striking part 713. The torsion spring 711 is installed on the rear side of the display frame 2 and extends horizontally. The torsion spring 711 is located above the striking hole 22 and opposite to it. The upper end of the connecting rod 712 is connected to the torsion spring 711. The arm is connected and its lower end is bent toward the display frame 2 to form an installation section. The striking part 713 is located at the end of the installation section. The support plate 72 is located in the slot and is movable in the vertical direction to support the fluorescent sign 3. Part of the support plate 72 passes through the through hole 23 and extends out of the display frame 2 to form a setting end. The upper end surface of the setting end is provided with a mounting post 72a. The blocking block 73 is located on the upper end surface of the mounting post 72a and between the display frame 2 and the striking part 713 to block the striking hole 22. The rear side of the blocking block 73 is provided with a groove 73a to fit with the end of the striking part 713. The groove 73a and the striking part 713 cooperate to suspend the support plate 72 under the traction of the torsion spring 711. When the fluorescent indicator 3 falls from the receiving channel 11 into the display frame 2, the gravity of the fluorescent plate causes the support plate 72 to move downward, thereby causing the blocking block 73 to move downward to expose the striking hole 22 and remove the supporting effect on the connecting rod 712 and the striking part 713. Thus, under the gravity of the connecting rod 712 and the striking part 713, the torsion spring 711 deforms, allowing the striking part 713 to pass through the striking hole 22 and break the glass tube 32 inside the fluorescent indicator 3. This causes the ester compound inside the glass tube 32 to flow out and react with the peroxide in the sealed cavity, thereby producing fluorescence.

[0060] In this embodiment, as Figure 1 and Figure 2As shown, a guide tube 8 is provided between the housing 1 and the display panel. The guide tube 8 extends vertically, and its two openings in the vertical direction are respectively connected to the cavity opening and the slot opening. The rear side of the guide tube 8 is inclined from top to bottom towards the display frame 2. By setting the guide tube 8, the two fluorescent panels in the housing 1 can share the same display frame 2, simplifying the structure of the display frame 2 and facilitating manufacturing. At the same time, by setting the length of the guide tube 8, the distance of the display frame 2 from the ground can be controlled, so that the display frame 2 has a suitable distance from the ground, so that escapers who are bending over can see it.

[0061] In this embodiment, as Figure 1 As shown, the fire escape indicator device 100 also includes an emergency indicator light 12, which is installed above the housing 1. In cases of low smoke concentration, the high position of the emergency indicator light 12 makes it easier for people escaping from a distance to spot it, thus providing guidance for people indoors to quickly find a safe passage.

[0062] In this embodiment, as Figure 10 As shown, the fire escape indicator device 100 also includes a dispersal mechanism 9, which includes a mounting box 91, a fan 92, and an air duct 93. The mounting box 91 is located on the upper surface of the housing 1. The mounting box 91 has an air inlet 91a on one side arranged in the left-right direction to allow the cavity of the mounting box 91 to communicate with the outside. The front side of the mounting box 91 has an air outlet 91b. The fan 92 is located inside the mounting box 91, with its air inlet facing the air inlet 91a. The air duct 93 is located inside the mounting box 91 and communicates with the air outlet 91b to guide the air blown by the fan 92 to the air outlet 91b. The emergency indicator light 12 is located outside the mounting box 91 and is located on the front side of the mounting box 91. The emergency indicator light 12 and the air outlet 91b are arranged side by side in the left-right direction. In this way, the air blown out by the fan 92 will clear away the smoke in front of the emergency indicator sign 12, allowing people escaping from a distance to see the direction indicated by the emergency indicator sign 12.

[0063] In this embodiment, as Figure 1 As shown, the upper surface of the mounting box 91 is provided with two lighting lamps 91c, which are spaced apart in the left-right direction. The two lighting lamps 91c can emit light to attract the attention of escaping personnel, thus making the fire escape indicator device 100 easy for escaping personnel to find.

[0064] In this embodiment, as Figure 9As shown, the display frame 2 has at least one support block 24 on its side facing the wall. The support block 24 is located near the lower end of the display frame 2 to abut against the wall. In this way, the display frame 2 and the housing 1 fit together against the wall, making the installation of the fire escape indicator device 100 more stable.

[0065] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
