Description

Technical Field

[0001] The present invention belongs to the technical field of signboards, and particularly relates to an intelligent monitoring emergency escape signboard. Background Art

[0002] In modern society, public places and buildings are densely populated. In the event of emergencies such as fires and earthquakes, rapid and safe evacuation of people is of utmost importance. As a key device for guiding people to evacuate, the performance of emergency escape signboards is directly related to people's lives. With the increasing complexity of building structures and the growing scale of people flow, higher requirements are put forward for the intelligence and reliability of emergency escape signboards.

[0003] Currently, the common emergency escape signboards on the market are mainly divided into traditional static signboards and some signboards with simple emergency functions. Traditional static signboards are mostly self-luminous or constantly lit with a battery, and can only provide escape signs in a fixed direction, which can play a basic guiding role in normal environments. Some signboards with slightly more functions, although equipped with simple emergency lighting that can briefly light up during power outages, have extremely limited effects in complex emergency scenarios.

[0004] Existing emergency escape signboards have many obvious deficiencies. From the perspective of emergency guidance functions, most signboards cannot perceive environmental changes in real time. When a large amount of smoke is generated during a fire, or when the passage is blocked due to other disasters, traditional signboards still indicate according to a fixed pattern, and cannot provide dynamic and reasonable escape routes for evacuating people. Their single indication method is difficult to be clearly recognized by people in the case of smoke-filled and obstructed vision, resulting in low evacuation efficiency, people being easily lost, and missing the best opportunity for escape. Summary of the Invention

[0005] In order to overcome the above defects, the present invention provides an intelligent monitoring emergency escape signboard, which solves the problems that traditional signboards still indicate according to a fixed pattern, cannot provide dynamic and reasonable escape routes for evacuating people, and their single indication method is difficult to be clearly recognized by people in the case of smoke-filled and obstructed vision, resulting in low evacuation efficiency and people being easily lost.

[0008] As a further solution of the present invention: A motor is installed inside the top of the outer frame, the output end of the motor penetrates through the outer frame and the top of the indicator board body and is fixedly connected to the driving gear coaxially, the top of the outer frame is fixedly connected with a protective cover through bolts, and the motor is located inside the protective cover.

[0009] As a further solution of the present invention: Connecting blocks are fixedly installed on the top inner part of the indicator board body in a symmetrical structure, the connecting blocks are of an L-shaped structure, and the connecting blocks are located below the driven gear and are rotatably connected to the driven gear.

[0010] As a further solution of the present invention: A limiting groove for cooperating with the second rack is opened on one side inside the indicator board body, and the first rack and the second rack are respectively meshed with the driven gear.

[0011] As a further solution of the present invention: The outer frame is made of alloy material, hooks are fixedly installed on the top of the outer frame in a symmetrical structure, and a connecting wire for cooperating with the indicator board body is connected to one side of the outer frame.

[0012] As a further solution of the present invention: Multiple groups of reflective strips are arranged on the outer surface of the first fixing block, and the reflective strips are made of a microprism-type reflective material with a high refractive index.

The first rack slides within the limit block, and the second rack slides within the limit groove on the inner side of the sign body. As the first rack and the second rack slide, the driven gears meshed with them start to rotate. The driven gears are fixed at the bottom end of the connecting rod, so the connecting rod will rotate together with the driven gears. The connecting block is of an L-shaped structure, located below the driven gear and rotatably connected thereto, playing a role in supporting and limiting the driven gear to ensure its stable rotation. The illuminating lamp fixedly connected to the top end of the connecting rod starts to rotate driven by the rotation of the connecting rod. At the same time, the control unit will control the illuminating lamp to turn on, emitting high-brightness light to provide illumination for the escape passage and guiding the personnel to evacuate.

Detailed implementation manners

[0023] The technical solutions of this patent will be further described in detail below in conjunction with the specific implementation manners.

[0024] As Figures 1 - 5 shown, the present invention provides a technical solution for an intelligent monitoring escape emergency sign:

[0025] It includes a sign body 1, an outer frame 2 is arranged on the outside of the sign body 1, a monitoring module 4 is fixedly installed on one side of the outer frame 2, the monitoring module 4 includes a smoke sensor and a temperature sensor, a first fixing block 5 is fixedly connected to the bottom of the outer frame 2, electric telescopic rods 13 are fixedly installed in the first fixing block 5 in a symmetrical structure, the output ends of the electric telescopic rods 13 are fixedly connected to a movable block 23, a projection mechanism 12 is fixedly connected between the movable blocks 23, a slot is opened at the bottom of the first fixing block 5, and a protective film 10 is arranged in the slot, the protective film 10 is located directly below the projection mechanism 12, the protective film 10 is composed of multiple plastic sheets, and a control unit for cooperating with the monitoring module 4 is integrated in the sign body 1;

[0026] Specifically, the smoke and temperature sensors in the monitoring module 4 continuously monitor the environment. Once the data exceeds the threshold, an emergency response is triggered. The electric telescopic rod 13 receives the instruction to extend, pushing the movable block 23 to drive the projection mechanism 12 to descend. At this time, the multiple plastic sheets of the protective film 10 block dust and other sundries, protecting the projection mechanism 12. The projection mechanism 12 is turned on to project escape information and the like onto the ground or the wall. The monitoring module 4 can quickly detect environmental anomalies, providing a basis for the emergency response. The electric telescopic rod 13 controls the lifting of the projection mechanism 12, which can be retracted when not in use, avoiding damage and saving space. The protective film 10 can prevent dust and sundries from entering the projection mechanism 12, extending its service life, ensuring the normal operation of the projection function in case of emergency, enabling the projection mechanism 12 to accurately present the escape indication, improving the personnel evacuation efficiency, and ensuring life safety;

[0027] On both sides of the top of the outer frame 2, second fixing blocks 7 are fixedly connected in a symmetric structure. A connecting rod 14 is rotatably connected inside the second fixing blocks 7. The top end of the connecting rod 14 is fixedly connected with a lighting lamp 8. The bottom end of the connecting rod 14 penetrates through the outer frame 2 and the sign body 1. The bottom end of the connecting rod 14 is fixedly connected with a driven gear 15. A second rack 18 is slidably connected inside the sign body 1. A limiting block 19 is fixedly connected to the inner top of the sign body 1. A first rack 17 is slidably connected inside the limiting block 19. A driving gear 21 is rotatably connected to the inner top of the sign body 1. The driving gear 21 is located between the first rack 17 and the second rack 18. A motor 22 is installed inside the top of the outer frame 2. The output end of the motor 22 penetrates through the outer frame 2 and the top of the sign body 1 and is fixedly connected to the driving gear 21 coaxially. The top of the outer frame 2 is fixedly connected with a protective cover 9 by bolts. The motor 22 is located inside the protective cover 9. Connecting blocks 16 are fixedly installed in a symmetric structure on the inner top of the sign body 1. The connecting blocks 16 are of an L-shaped structure and are located below the driven gear 15 and are rotatably connected to the driven gear 15;

[0028] Specifically, when the monitoring module 4 detects that environmental parameters such as smoke concentration or temperature reach a preset emergency threshold, it will send a signal to the control unit. After receiving the signal, the control unit determines it as an emergency situation and then starts the motor 22. The motor 22 starts to work, and its output end drives the driving gear 21 fixedly connected to it coaxially to rotate. Since the driving gear 21 is located between the first rack 17 and the second rack 18 and they are all meshed with each other, the rotation of the driving gear 21 will push the first rack 17 and the second rack 18 to slide along their respective tracks. The first rack 17 slides inside the limiting block 19, and the second rack 18 slides inside the limiting groove 20 on the inner side of the sign body 1. As the first rack 17 and the second rack 18 slide, the driven gear 15 meshed with them starts to rotate. The driven gear 15 is fixed to the bottom end of the connecting rod 14. Therefore, the connecting rod 14 will rotate together with the driven gear 15. The connecting blocks 16 are of an L-shaped structure, located below the driven gear 15 and rotatably connected to it, playing a role in supporting and limiting the driven gear 15 to ensure its stable rotation. The lighting lamp 8 fixedly connected to the top end of the connecting rod 14 starts to rotate under the drive of the rotation of the connecting rod 14. At the same time, the control unit will control the lighting lamp 8 to turn on and emit high-brightness light to provide lighting for the escape passage and guide the evacuation of personnel. The protective cover 9 fixedly connected to the top of the outer frame 2 by bolts always protects the internal motor 22 during the whole process. The protective cover 9 is made of fireproof, dustproof and waterproof sealing materials, which can effectively block external fire high temperature, dust and water vapor, etc., avoiding the damage of the motor 22 due to the influence of these factors and ensuring that the motor 22 can operate normally and stably to provide continuous power for the whole lighting and driving system;

[0029] A limiting groove 20 for cooperating with the second rack 18 is provided on one side inside the sign body 1. The first rack 17 and the second rack 18 are respectively engaged with the driven gear 15. The outer frame 2 is made of alloy material, and hooks 6 are fixedly installed at the top of the outer frame 2 in a symmetrical structure. A connecting line 3 for cooperating with the sign body 1 is connected to one side of the outer frame 2. A plurality of reflective strips 11 are arranged on the outer surface of the first fixing block 5. The reflective strips 11 are made of a microprism-type reflective material with a high refractive index. The projection mechanism 12 includes a micro-projector and an adjustment component for adjusting the projection angle and focal length, and the adjustment component is connected to the movable block 23, and the projection mechanism 12 can be driven to move by the telescopic movement of the electric telescopic rod 13;

[0030] Specifically, when the motor 22 drives the driving gear 21 to rotate, thereby driving the first rack 17 and the second rack 18 to move, the second rack 18 slides in the limiting groove 20 opened on one side inside the sign body 1. The limiting groove 20 provides an accurate sliding track for the second rack 18 to ensure the accuracy of its moving direction. Cooperating with the first rack 17, they jointly drive the driven gear 15 to rotate smoothly. During the entire transmission process, the first rack 17 and the second rack 18 are respectively in close meshing with the driven gear 15, converting the linear motion into the circular motion of the driven gear 15, thereby driving the connecting rod 14 and the lighting lamp 8 connected thereto to rotate. When installing the sign, the staff can conveniently hang the sign at the designated position through the hook 6. The connecting wire 3 connected to one side of the outer frame 2 is responsible for transmitting the power of the external power supply to the sign body 1 during the normal operation of the device, providing stable power supply for each power-consuming component such as the internal monitoring module 4, the motor 22, and the projection mechanism 12; at the same time, the connecting wire 3 also undertakes the task of signal transmission, transmitting signals such as the environmental data collected by the monitoring module 4 and the control instructions issued by the control unit between the components inside the sign and between the sign and the external control center. Under normal light or emergency lighting conditions, the light irradiates on the reflective strip 11 provided on the outer surface of the first fixing block 5. Since the reflective strip 11 is made of a microprism-type reflective material with a high refractive index, after the light enters the microprism structure, it will be reflected multiple times inside and then reflected back along a direction substantially opposite to the incident light. In this way, in a dark environment or a smoky environment with low visibility, whether it is the light of a flashlight in the hands of the evacuees or the light emitted by other surrounding emergency lighting devices, when it irradiates on the reflective strip 11, it can be strongly reflected back, attracting the attention of the evacuees, thereby helping them quickly identify the position of the sign. When the monitoring module 4 detects an emergency, the control unit issues an instruction, and the electric telescopic rod 13 starts to work. The electric telescopic rod 13 extends or contracts, driving the connected movable block 23 to move. Since the adjustment component of the projection mechanism 12 is connected to the movable block 23, the movement of the movable block 23 will prompt the adjustment component to adjust the angle and focal length of the projection mechanism 12 to ensure that the projection screen is clearly and completely presented in the target area, such as the ground or the wall, providing detailed escape guidance information for the evacuees, such as a dynamic escape route map and the location sign of the safety exit, providing the most effective escape guidance for the evacuees and meeting the emergency indication requirements in different scenarios;

[0031] The working principle of the present invention is as follows:

[0032] First, the smoke sensor and the temperature sensor in the monitoring module 4 continuously monitor the surrounding environment. Once data such as the smoke concentration and temperature exceed the preset threshold, the monitoring module 4 immediately sends a signal to the control unit integrated in the sign body 1 to trigger the emergency response mechanism;

[0033] Secondly, when the control unit receives the emergency signal transmitted from the monitoring module 4, it quickly activates the corresponding devices. On the one hand, it controls the operation of the motor 22. The output end of the motor 22 drives the driving gear 21 to rotate. The driving gear 21 meshes with the first rack 17 and the second rack 18, prompting the two to slide along their respective tracks. The second rack 18 slides stably under the precise limitation of the limiting groove 20 and cooperates with the first rack 17 to drive the driven gear 15. The driven gear 15 drives the connecting rod 14 connected thereto to rotate, and then the lighting lamp 8 at the top of the connecting rod 14 is turned on and rotated to provide 360-degree dead-angle-free lighting for the escape passage. On the other hand, it controls the electric telescopic rod 13 to extend. The electric telescopic rod 13 pushes the movable block 23 to drive the projection mechanism 12 to descend. At the same time, the adjustment component of the projection mechanism 12 adjusts the projection angle and focal length according to the movement of the movable block 23. Subsequently, the projection mechanism 12 is turned on to project escape information such as dynamic escape route maps and safety exit position signs onto the ground or wall to provide intuitive and detailed escape guidance for the evacuated personnel;

[0034] It is worth mentioning that the protective film 10 is composed of multiple groups of plastic sheets and is located directly below the projection mechanism 12. When the projection mechanism 12 descends, the protective film 10 blocks dust and other sundries to prevent them from entering the projection mechanism 12, extends the service life of the projection mechanism 12, and ensures the normal operation of the projection function in case of emergency. The protective cover 9 on the top of the outer frame 2 is made of fireproof, dustproof, and waterproof sealing materials to always protect the internal motor 22 from the influence of fire high temperature, dust, and water vapor, ensuring the stable operation of the motor 22 and continuously supplying energy for the lighting and drive systems. The reflective strip 11 on the outer surface of the first fixing block 5 is made of a microprismatic reflective material with a high refractive index. In low visibility environments such as darkness or smoke-filled areas, after the light shines on the reflective strip 11, it is strongly reflected back after multiple reflections to attract the attention of the evacuated personnel and assist in identifying the position of the sign;

[0035] Finally, the outer frame 2 is made of alloy material, which is strong, durable, and lightweight. The hooks 6 symmetrically installed on its top facilitate the staff to conveniently hang the sign at the designated position. The connecting wire 3 connected to one side undertakes dual tasks. It not only transmits stable power to the electrical components such as the monitoring module 4, the motor 22, and the projection mechanism 12, but also is responsible for transmitting monitoring data and control instructions between the components inside the sign and the external control center to achieve the intelligent control and coordinated operation of the sign.

[0036] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of this patent.
