Description

Technical Field

[0001] This utility model relates to the field of safety passage guidance structures, and in particular to a safety passage guidance structure for emergency use in tunnel fires. Background Technology

[0002] Currently, Chinese patent CN212694762U discloses a smart community safety passage guidance system. This system includes a passage guidance light body; a base plate disposed behind the passage guidance light body; a first fixing strip fixedly installed on the top of the passage guidance light body; a second fixing strip fixedly installed on one side of the base plate above the passage guidance light body; a support plate fixedly installed on the first and second fixing strips; two sliding grooves, both formed on the side of the base plate away from the passage guidance light body; and two fixing mechanisms. This smart community safety passage guidance system offers advantages such as convenient installation, good stability, easy replacement, and easy maintenance.

[0003] Emergency tunnel fire safety passage guidance structures refer to a series of facilities specifically installed in tunnels to quickly and accurately guide personnel to safe areas in emergencies such as fires. They can release fire information and evacuation instructions in real time, directing personnel to evacuate in an orderly manner and avoiding chaos and congestion. However, the height of existing emergency tunnel fire safety passage guidance structures is mostly fixed, making it difficult to adapt to the dynamic changes in smoke layers during a fire. Smoke often obscures the guidance signs, making it impossible for personnel to find the evacuation direction in time. Furthermore, the signs only have simple static displays and lack eye-catching dynamic elements. In the dimly lit, chaotic, and noisy fire scene, it is difficult to quickly capture people's attention. Moreover, most guidance structures lack protective measures, and the guidance signs are easily damaged by secondary damage caused by fire, greatly reducing the efficiency of personnel evacuation. Utility Model Content

[0004] The main purpose of this utility model is to provide a safety passage guidance structure for emergency tunnel fires. This addresses the problems of existing safety passage guidance structures for emergency tunnel fires, which are mostly fixed in height, making it difficult to adapt to dynamic changes in smoke layers during a fire. Smoke often obscures the guidance signs, preventing people from quickly identifying evacuation directions. Furthermore, the signs are often simple and static, lacking eye-catching dynamic elements, making it difficult to quickly capture people's attention in dimly lit, chaotic, and noisy fire scenes. Moreover, most guidance structures lack protective measures, making them highly susceptible to secondary damage from fires, significantly reducing evacuation efficiency.

[0005] To achieve the above objectives, this utility model proposes a safety passage guidance structure for tunnel fire emergency use, including a guide sign, a lifting and mounting mechanism bolted to the top of the guide sign, a road sign at the bottom of the guide sign, an indicator sign bolted to the front of the road sign, an emergency flashing light at the front of the indicator sign, a player at the bottom of the guide sign, and a protective frame at the front of the guide sign.

[0006] Preferably, the lifting and installation mechanism includes a pre-installed plate, an electric lifting assembly, and an installation plate. The bottom of the installation plate is bolted to the top of the guide sign, the top of the installation plate is bolted to the bottom of the electric lifting assembly, and the top of the electric lifting assembly is bolted to the bottom of the pre-installed plate.

[0007] Preferably, a fixing block is bolted to the bottom of the guide sign, and a connecting block is bolted to the bottom of the fixing block.

[0008] Preferably, the connecting block is bolted to the road sign on the side closest to the road sign, the top of the connecting block is bolted to the bottom of the player, and an enhanced lighting lamp is bolted to the bottom of the connecting block.

[0009] Preferably, a pre-installation knob is movably connected to the inner wall of the pre-installation plate, and the inner wall of the pre-installation plate has mounting holes that cooperate with the pre-installation knob.

[0010] Preferably, a sealing ring is bonded to the rear side of the protective frame, and the surface of the sealing ring engages with the inner wall of the guide sign.

[0011] Preferably, the inner wall of the guide sign is provided with a sealing groove that cooperates with the sealing ring, and the inner wall of the protective frame is fixedly connected with a transparent plate.

[0012] Preferably, a rotating assembly is bolted to the top of the protective frame, and the bottom of the rotating assembly is bolted to the top of the guide sign.

[0013] In this utility model's technical solution, guide signs, a lifting and installation mechanism, road signs, directional signs, emergency flashing lights, a player, and a protective frame are installed. During use, the position of the guide signs is fixed by the lifting and installation mechanism, facilitating the raising and lowering of the guide signs. In dense smoke environments caused by fires, the guide signs can be quickly lowered to a clearly visible position based on changes in the smoke layer, ensuring that on-site personnel can promptly obtain evacuation direction information. Road signs, combined with directional signs, use eye-catching markings and clear arrows to intuitively present the direction of safety passages, pointing out accurate paths to panicked personnel. The high-frequency flashing of the emergency flashing lights can penetrate dense smoke and dim light, attracting people's attention. Even with limited visibility, it allows people to quickly locate the guide signs. The player can play pre-recorded, clear, and concise evacuation voice prompts at critical moments, providing multi-faceted assistance to personnel in quickly deciding on evacuation routes.

[0027] This utility model provides a safety passage guidance structure for emergency tunnel fires, aiming to solve the problems of existing safety passage guidance structures for emergency tunnel fires, which are mostly fixed in height and cannot adapt to the dynamic changes of smoke layers during a fire. Smoke often obscures the guidance signs, making it impossible for people to find the evacuation direction in time. In addition, the signs are only simple static displays and lack eye-catching dynamic elements. In the dim light and chaotic fire scene, they are difficult to quickly attract people's attention. Moreover, most guidance structures do not have protective measures. In the face of secondary damage that can easily be caused by fire, the guidance signs are easily damaged, which greatly reduces the efficiency of personnel evacuation.

[0028] like Figure 1-6 As shown in the figure, the present invention provides a tunnel fire emergency safety passage guidance structure, including a guide sign 1, a lifting installation mechanism 2 bolted to the top of the guide sign 1, a road sign 3 set at the bottom of the guide sign 1, an indicator 4 bolted to the front of the road sign 3, an emergency flashing light 5 set at the front of the indicator 4, a player 6 set at the bottom of the guide sign 1, and a protective frame 7 set at the front of the guide sign 1.

[0029] In this utility model's technical solution, a guide sign 1, a lifting installation mechanism 2, a road sign 3, an indicator sign 4, an emergency flashing light 5, a player 6, and a protective frame 7 are set up. During use, the lifting installation mechanism 2 is used to fix the guide sign 1 in place, facilitating the raising and lowering of the guide sign 1 via the mechanism 2. In dense smoke environments caused by fires, the guide sign 1 can be quickly lowered to a clearly visible position based on changes in the smoke layer, ensuring that on-site personnel can promptly obtain evacuation direction information. The road sign 3, paired with the indicator sign 4, uses eye-catching markings and clear arrows to intuitively present the direction of the safety passage, pointing out the accurate path for panicked personnel. The high-frequency flashing of the emergency flashing light 5 can penetrate dense smoke and dim light, attracting personnel's attention. Even with limited visibility, it allows personnel to quickly locate the guide sign 1. The player 6 can play pre-recorded, clear, and concise evacuation voice prompts at critical moments, providing multi-faceted assistance to personnel in quickly deciding on evacuation routes.

[0030] Please refer to the following: Figure 2 The lifting and installation mechanism 2 includes a pre-installed plate 201, an electric lifting assembly 202, and an installation plate 203. The bottom of the installation plate 203 is bolted to the top of the guide sign 1, the top of the installation plate 203 is bolted to the bottom of the electric lifting assembly 202, and the top of the electric lifting assembly 202 is bolted to the bottom of the pre-installed plate 201. In this embodiment, by setting the pre-installed plate 201, the electric lifting assembly 202, and the installation plate 203, the guide sign 1 is provided with a flexible height adjustment function. The pre-installed plate 201 is convenient for pre-installation and positioning in the tunnel. The electric lifting assembly 202, as the core power source, can drive the guide sign 1 to rise or fall according to the actual situation such as the smoke concentration and the height of personnel when a fire occurs in the tunnel. This ensures that key directional information such as the road sign 3 and the indicator sign 4 are always at the optimal visibility height, effectively avoiding obstruction by dense smoke, and allowing personnel to clearly see the evacuation direction whether walking or driving.

[0031] For further information, please continue to refer to [link / reference]. Figure 6 A fixing block 8 is bolted to the bottom of the guide sign 1, and a connecting block 9 is bolted to the bottom of the fixing block 8. In this embodiment, by setting the fixing block 8 and the connecting block 9, the fixing is achieved by the position of the fixing block 8 and the connecting block 9, which facilitates the subsequent stable support and fixing work of the connecting block 9.

[0032] Please continue to refer to this. Figure 6 The connecting block 9 is bolted to the road sign 3 on the side closest to the road sign 3, and the top of the connecting block 9 is bolted to the bottom of the player 6. An enhanced lighting lamp 10 is bolted to the bottom of the connecting block 9. In this embodiment, the connection between the connecting block 9 and the road sign 3 facilitates stable subsequent indication by the road sign 3. The enhanced lighting lamp 10, which is fixed in place by its position relative to the connecting block 9, enhances guidance capabilities in dimly lit environments caused by fires.

[0033] Please refer to Figure 2 A pre-installation knob 11 is movably connected to the inner wall of the pre-installation plate 201, and an installation hole 12 is provided on the inner wall of the pre-installation plate 201 to cooperate with the pre-installation knob 11. In this embodiment, by setting the pre-installation knob 11, the installation process of the lifting installation mechanism 2 is simplified. When the construction personnel install it in the tunnel, they can easily fix the pre-installation plate 201 in the predetermined position by rotating the pre-installation knob 11. The operation is convenient and efficient. The installation hole 12 provided on the inner wall of the pre-installation plate 201 facilitates the movable connection between the pre-installation knob 11 and the pre-installation plate 201.

[0034] Additionally, please refer to Figure 4 A sealing ring 13 is adhered to the rear side of the protective frame 7, and the surface of the sealing ring 13 engages with the inner wall of the guide sign 1. In this embodiment, by setting the sealing ring 13, the sealing ring 13 adhered to the rear side of the protective frame 7 engages with the inner wall of the guide sign 1, forming a tight protective barrier. At the fire scene, when a large amount of dust and smoke are present, the sealing ring 13 effectively prevents these impurities from entering the interior of the guide sign 1, protecting the internal electronic components from corrosion and damage.

[0035] Additionally, please refer to Figure 3 and Figure 4 The inner wall of the guide sign 1 has a sealing groove 14 that mates with the sealing ring 13, and the inner wall of the protective frame 7 is fixedly connected with a transparent plate 15. In this embodiment, the sealing groove 14 on the inner wall of the guide sign 1 facilitates the sealing ring 13 to be snapped into the inner wall of the guide sign 1, further enhancing the sealing effect. The transparent plate 15 on the inner wall of the protective frame 7 blocks the impact of external foreign objects while not affecting people's viewing of key directional information such as the road sign 3 and the indicator sign 4, maintaining clear and unobstructed visual guidance.

[0036] Additionally, please refer to Figure 5 A rotating assembly 16 is bolted to the top of the protective frame 7, and the bottom of the rotating assembly 16 is bolted to the top of the guide sign 1. In this embodiment, by setting the rotating assembly 16, the position of the rotating assembly 16 and the protective frame 7 is fixed, which facilitates the easy opening of the protective frame 7 during subsequent maintenance.
