Description

Technical Field

[0001] This utility model relates to the field of air-supported membrane structures, specifically a rapid evacuation warning device for air-supported membrane structures. Background Technology

[0002] Air-supported membrane structures use high-performance fabric materials and a mesh system attached to the outer membrane as the main materials. By supplying air and pressurizing it to the interior through an outdoor air supply and pressurization fan, a slight positive pressure is created inside. The air pressure supports the membrane surface, thus forming a large-span, large-space structural system with a certain rigidity and strength. This type of building has advantages such as large space and fast construction speed, but it also has some safety hazards. When a fire or other dangerous situation occurs inside, the dense smoke generated inside the air-supported membrane and the collapse after the membrane material breaks may prevent people from recognizing the emergency evacuation door in time, thus leaving them trapped inside and causing safety accidents. Therefore, a rapid evacuation warning device for air-supported membrane structures is needed.

[0003] Existing rapid evacuation warning devices for air-supported membrane structures have limitations when operating. These limitations become apparent when the internal layout of the structure changes due to events, adjustments to material storage, or when evacuation routes need to be adjusted in real-time based on hazard locations and personnel distribution in emergencies. In time-sensitive emergencies, timely changes in directional guidance are impossible, resulting in inaccurate escape guidance and significantly increasing evacuation risks. Furthermore, the relatively enclosed yet open interior space of air-supported membrane structures is affected by various factors. To maintain structural stability, continuous airflow is required, creating air circulation. When used for sporting events or large gatherings, the dense movement of people and the operation of air conditioning and ventilation equipment further exacerbate this airflow complexity, making the devices prone to swaying and affecting guidance. This can also lead to startled individuals not paying attention to evacuation warnings promptly. Therefore, a rapid evacuation warning device for air-supported membrane structures is urgently needed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a rapid evacuation warning device for air-supported membrane structures, in order to solve the problem that existing rapid evacuation warning devices for air-supported membrane structures have limitations when used. These limitations become apparent when the internal layout of the air-supported membrane structure changes due to events, adjustments to material storage, or when evacuation routes need to be adjusted in real time based on the location of hazards and the distribution of people in emergency situations. In urgent situations with limited time, it is impossible to change the directional direction in time, resulting in the evacuation warnings failing to provide accurate escape guidance and greatly increasing evacuation risks. The internal space of an air-supported membrane structure is relatively enclosed yet open, and airflow is affected by various factors. To maintain the stability of the air-supported membrane structure, continuous airflow is required, which creates a certain airflow circulation. When the air-supported membrane structure is used for events such as sports competitions and large gatherings, the dense activity of people and the operation of air conditioning and ventilation equipment further exacerbate the complexity of the airflow, making the device susceptible to violent shaking due to airflow, affecting guidance and causing people to be easily startled and unable to pay attention to the evacuation warnings in time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid evacuation warning device for air-supported membrane structures, comprising a mounting base, a first connecting chain welded to the outer wall of the mounting base, a mounting frame welded to one end of the first connecting chain, positioning rods fixedly connected to the inner walls of the mounting frame, an indicator box fixedly connected to the outer wall of the positioning rods, a light-emitting lamp installed on the inner wall of the indicator box, a wire electrically connected to the outer wall of the light-emitting lamp, and guide plates installed on the inner walls of the indicator box.

[0006] A second connecting chain is welded to the lower end of the indicator box, and a connecting cover is welded to one end of the second connecting chain. A placement cover is fixedly connected to the lower end of the connecting cover, and a weighted ball is installed on the inner wall of the placement cover.

[0007] Preferably, the mounting bracket is threadedly connected to the positioning rod, and the positioning rod is symmetrically arranged about the central axis of the mounting bracket.

[0008] Preferably, the indicator box is connected to the light source, and the inner wall of the indicator box has a slotted design.

[0009] Preferably, the indicator box is engaged with the guide plate, and the guide plate is symmetrically arranged about the central axis of the indicator box.

[0010] Preferably, the second connecting chain is arranged perpendicularly to the connecting cover, and the inner wall of the connecting cover is threaded.

[0011] Preferably, the connecting cover is threadedly connected to the placement cover, and the outer wall of the placement cover is threaded.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses an indicator box to lock and fix the guide plate. When using the device, the indicator box and the guide plate are set up so that when the internal layout of the air-supported structure changes due to events, material storage adjustments, or when the evacuation route needs to be quickly adjusted according to the location of the hazard source and the distribution of personnel in an emergency, the guide direction can be changed in a timely manner, reducing the risk of evacuation prompts failing to provide accurate escape guidance to personnel.

[0014] 2. This utility model uses a placement cover to lock and fix the weighted ball. By placing the weighted ball inside the placement cover below the indicator box, the center of gravity of the indicator box is significantly lowered. The lower the center of gravity, the more stable the object is when subjected to external forces and airflow impact. Under the same strong airflow environment, the shaking amplitude of the indicator box is greatly reduced, and it always maintains a stable indicating direction. At the same time, the slight shaking and collision of the weighted ball inside the placement cover generates sound, which increases the attraction of the device in an emergency, ensuring that evacuees can see it in time and that the prompt information can be accurately conveyed to the people inside the facility.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4A rapid evacuation warning device for air-supported membrane structures includes a mounting base 1. A first connecting chain 2 is welded to the outer wall of the mounting base 1. A mounting frame 3 is welded to one end of the first connecting chain 2. Positioning rods 4 are fixedly connected to the inner walls of the mounting frame 3. The mounting frame 3 and the positioning rods 4 are threadedly connected, and the positioning rods 4 are symmetrically arranged about the central axis of the mounting frame 3. An indicator box 5 is fixedly connected to the outer wall of the positioning rods 4. A light lamp 6 is installed on the inner wall of the indicator box 5. The indicator box 5 and the light lamp 6 are engaged. The inner wall of the indicator box 5 has a slotted design. A wire 7 is electrically connected to the outer wall of the light lamp 6. The inner wall of the indicator box 5 is... The device is equipped with a guide plate 8, and the indicator box 5 is engaged with the guide plate 8. The guide plate 8 is symmetrically arranged with respect to the central axis of the indicator box 5. The indicator box 5 is used to engage and fix the guide plate 8. When using the device, the arrangement of the indicator box 5 and the guide plate 8 makes it easy to change the direction of guidance in a timely manner when the internal layout of the air-supported structure changes due to events, adjustments to material storage, or when it is necessary to quickly adjust the evacuation route according to factors such as the location of the hazard source and the distribution of personnel in an emergency. This reduces the risk of evacuation prompts failing to provide accurate escape guidance to personnel.

[0023] Please see Figure 1-4 A rapid evacuation warning device for air-supported membrane structures includes an indicator box 5 with a second connecting chain 9 welded to its lower end. One end of the second connecting chain 9 is welded to a connecting cover 10. The second connecting chain 9 and the connecting cover 10 are perpendicularly arranged, and the inner wall of the connecting cover 10 is threaded. A placement cover 11 is fixedly connected to the lower end of the connecting cover 10, and the connecting cover 10 and the placement cover 11 are threaded together. The outer wall of the placement cover 11 is threaded, and a weighted ball 12 is installed on the inner wall of the placement cover 11. The placement cover 11 secures the weighted ball 12 in place. The weighted ball 12 is placed inside the placement cover 11 below the indicator box 5, which significantly lowers the center of gravity of the indicator box 5. The lower the center of gravity, the more stable the object is when subjected to external forces and airflow impact. Under the same strong airflow environment, the shaking amplitude of the indicator box 5 is greatly reduced, and it always maintains a stable indication direction. At the same time, the weighted ball 12 shakes and collides slightly inside the placement cover 11, generating sound, which increases the attraction of the device in an emergency, ensuring that evacuees can see it in time and that the prompt information can be accurately conveyed to the people in the venue.

[0024] Working principle: When in use, take out the device and place it in the designated position. Attach the mounting bracket 3 to the indicator box 5, then thread the positioning rod 4 to fix the mounting bracket 3 and indicator box 5 together. Next, snap the light 6 onto the indicator box 5, then snap the indicator box 5 onto the guide plate 8. Place the weighted ball 12 inside the placement cover 11, then thread the connecting cover 10 onto the placement cover 11. Install the mounting base 1 on the air-supported structure support frame. Finally, turn on the light 6, allowing the light source to shine through the slot in the inner wall of the guide plate 8 for evacuation guidance. This completes the device's operation.
