TECHNICAL FIELD

[0001] The present application relates to the technical field of air film buildings, and particularly relates to an air film state monitoring and early warning device for air film buildings. BACKGROUND

[0004] The existing air film building is usually capped with an air film, and the bottom is supported and fixed by a building body. When the air film capping is scratched by aging of the material, falling objects or sharp objects, the air film is easily damaged, which reduces the internal pressure of the air film and has great safety risks. Moreover, the air film has a large volume and the use of sensors for monitoring has a high cost. The sensors are easily affected by the external environment, have low reliability, are difficult to popularize on a large scale, and it is difficult to find the damaged part of the air film. Due to the special structure, it is difficult to repair in the short term.

[0005] Therefore, it is necessary to provide an air film state monitoring and early warning device for air film buildings to solve the above technical problems. SUMMARY

[0006] The present application relates to the technical field of air film buildings, and particularly relates to an air film state monitoring and early warning device for air film buildings.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an air-supported membrane structure status monitoring and early warning device, comprising a building body, an air-supported membrane structure fixedly connected to the middle of the upper end face of the building body, an inflation device for pressurizing the air-supported membrane structure installed on the upper end face of the building body, at least one set of structural reinforcing ribs interlaced inside the air-supported membrane structure, multiple monitoring mechanisms for monitoring the status of the air-supported membrane structure fixedly connected to the bottom of the structural reinforcing ribs, each monitoring mechanism comprising a sealing mechanism and a monitoring sensor plate, the sealing mechanism being fixedly connected to the bottom of the structural reinforcing ribs, the monitoring sensor plate being elastically connected to the end of the sealing mechanism opposite to the structural reinforcing ribs, and the monitoring sensor plate being vertically arranged relative to the air-supported membrane structure, the inner wall of the air-supported membrane structure being embedded with a first suction part and a second suction part for suction and limiting the monitoring sensor plate.

[0008] As a further embodiment of the present invention, the lower end face of the sealing mechanism is provided with a limiting baffle that fits against one side of the monitoring sensor plate, and the edge of the monitoring sensor plate away from the limiting baffle is provided with an arc-shaped part that fits against the building air film.

[0009] As a further embodiment of the present invention, a third suction part is provided on the surface of the arc-shaped part, which is adapted to the first suction part and the second suction part, and the first suction part, the second suction part and the third suction part are magnetically attracted to each other.

[0010] As a further embodiment of the present invention, the closing mechanism includes a closing mechanism body, a sensing pressure rod, a filling device, and a connecting plate. The closing mechanism body is fixedly connected to the lower end face of the structural reinforcing rib. The sensing pressure rod is elastically embedded in the middle of the lower end face of the closing mechanism body. The connecting plate is fixedly connected to both sides of the lower end face of the closing mechanism body. The filling device is elastically connected between the two sets of connecting plates, and the sensing pressure rod protrudes from the lower surface of the closing mechanism body.

[0011] As a further embodiment of the present invention, the filling device includes a filling device body, a connecting shaft, an opening, a connecting shaft and a limiting gear. The limiting gear is rotatably embedded in the middle of the connecting plate through the connecting shaft. The connecting shaft is fixedly connected to the middle of the limiting gear. The filling device body is elastically sleeved on the outer end face of the connecting shaft. The opening is formed on the outer surface of the filling device body.

[0012] As a further embodiment of the present invention, a sealing cavity is provided inside the main body of the filling device, a partition is provided in the middle of the sealing cavity, piston plates are provided on both sides of the partition, a spiral spring is embedded inside the main body of the filling device, one end of the spiral spring away from the main body of the filling device is elastically connected to the connecting shaft, a screw groove is provided at the contact point between the piston plate and the connecting shaft, the sealing cavity is connected to the opening, and the sealing cavity is filled with sealant.

[0013] As a further embodiment of the present invention, the connecting plate has a rotating groove adapted to the limiting gear inside, the rotating groove is connected to a spring groove, and a movable plate is elastically connected inside the spring groove by a spring.

Multiple sets of structural reinforcing ribs are horizontally arranged within the membrane, effectively improving its stability. A monitoring mechanism is also included to prevent damage from external forces or sharp objects that could cause the membrane to collapse due to reduced internal pressure. The invention incorporates a sealing mechanism and a monitoring sensor plate. The sensor plate is elastically connected to the lower part of the sealing mechanism and perpendicular to the tangent of the air-supported membrane under elastic force. When a rupture occurs on the surface of the membrane, the positive pressure inside causes gas to flow rapidly out through the rupture, deflecting the monitoring sensor plate around the rupture. The amount of deflection of the monitoring sensor plate can indicate the leakage situation. Simultaneously, when the monitoring sensor plate deflects, a first and second suction part are provided on the inner wall of the building's air-supported membrane. These two suction parts pull the deflected monitoring sensor plate further, causing it to deflect and adhere to the building's air-supported membrane. By providing sealing structures such as sealing rings on the surface of the monitoring sensor plate, the damaged area can be effectively sealed temporarily after contact with the building's air-supported membrane, preventing further reduction in internal pressure and ensuring the building's stability. Furthermore, the deflected monitoring sensor plate is easily observable after adhering to the building's air-supported membrane, facilitating warnings to personnel inside. By incorporating multiple monitoring mechanisms, comprehensive monitoring of damage to the building's air-supported membrane can be achieved. The use of lightweight materials in the monitoring mechanisms helps improve monitoring sensitivity while reducing the weight load on the building's air-supported membrane.

[0028] Example 1

[0029] like Figures 1-6 As shown, an air-supported membrane structure status monitoring and early warning device includes a building body 4, an air-supported membrane 1 fixedly connected to the middle of the upper end face of the building body 4, an inflation device 3 for pressurizing the air-supported membrane 1 installed on the upper end face of the building body 4, at least one set of structural reinforcing ribs 2 interlaced inside the air-supported membrane 1, multiple monitoring mechanisms for monitoring the status of the air-supported membrane 1 fixedly connected to the bottom of the structural reinforcing ribs 2, the monitoring mechanism including a sealing mechanism 5 and a monitoring sensor plate 6, the sealing mechanism 5 being fixedly connected to the bottom of the structural reinforcing ribs 2, the monitoring sensor plate 6 being elastically connected to the end of the sealing mechanism 5 away from the structural reinforcing ribs 2, and the monitoring sensor plate 6 being vertically arranged relative to the air-supported membrane 1, the inner wall of the air-supported membrane 1 being embedded with a first suction part 7 and a second suction part 8 for suction and limiting the monitoring sensor plate 6.

[0030] During use, the inflation device 3 pressurizes the interior of the building air-supported membrane 1, ensuring a constant positive pressure inside. Multiple sets of structural reinforcing ribs 2 are horizontally arranged within the air-supported membrane 1, effectively improving its structural stability. A monitoring mechanism is also included to prevent damage from external forces or sharp objects that could cause the air-supported membrane 1 to collapse due to reduced internal pressure. A sealing mechanism 5 and a monitoring sensor 6 are included. The monitoring sensor 6 is elastically connected to the lower part of the sealing mechanism 5 and is perpendicular to the tangent of the air-supported membrane 1 under elastic force. When a rupture occurs on the surface of the air-supported membrane 1, the gas, under positive pressure, rapidly flows out through the rupture, causing the monitoring sensor 6 around the ruptured area to deflect due to the gas flow. The monitoring sensor 6 is then monitored. The amount of deflection can indicate the leakage situation. At the same time, when the monitoring sensor plate 6 deflects, the first suction part 7 and the second suction part 8 are provided on the inner wall of the building air membrane 1. The first suction part 7 and the second suction part 8 pull the deflected monitoring sensor plate 6, causing the monitoring sensor plate 6 to deflect further and adhere to the building air membrane 1. By providing sealing structures such as sealing rings on the surface of the monitoring sensor plate 6, the damaged area can be effectively sealed temporarily after the monitoring sensor plate 6 contacts the building air membrane 1, preventing the internal pressure from further decreasing and affecting the stability of the building. Moreover, after the monitoring sensor plate 6 deflects and adheres to the building air membrane 1, it is easy to observe and facilitate the warning to the personnel inside. By setting up multiple sets of monitoring mechanisms, the damage monitoring of the building air membrane 1 can be realized in all directions. In addition, the monitoring mechanism uses lightweight materials, which helps to improve the monitoring sensitivity while reducing the weight load on the building air membrane 1.

[0031] Example 2

[0032] Based on Example 1, such as Figures 1-6 As shown, the lower end face of the sealing mechanism 5 is provided with a limiting baffle 9 that fits against one side of the monitoring sensor plate 6, and the edge of the monitoring sensor plate 6 away from the limiting baffle 9 is provided with an arc-shaped part that fits against the building air membrane 1.

[0033] In use, to prevent the airflow at the damaged area from simultaneously pulling the adjacent monitoring sensor plates 6 to deflect, causing mutual interference between the two sets of adjacent monitoring sensor plates 6, a limit baffle 9 is set to limit the rotation of the monitoring sensor plates 6, so that the monitoring sensor plates 6 can only deflect in one direction. Under normal conditions, the monitoring sensor plates 6 are perpendicular to the tangent direction of the building air membrane 1 through the elastic element. When there is a damaged area, the airflow pushes the monitoring sensor plates 6 to deflect in one direction and, under the action of the first suction part 7 and the second suction part 8, they adhere to the building air membrane 1 to seal the damaged area.

[0034] like Figures 1-6As shown, a third suction part 12 is provided on the surface of the arc-shaped part, which is adapted to the first suction part 7 and the second suction part 8. The first suction part 7, the second suction part 8 and the third suction part 12 are magnetically attracted to each other.

[0035] In use, the first suction part 7 and the second suction part 8 can be configured as flexible magnetic sheets embedded in the inner wall of the building air membrane 1. The cross arrangement of the first suction part 7 and the second suction part 8 can further improve the structural strength of the building air membrane 1. At the same time, the use of flexible materials can make the building air membrane 1 more regular when stored. The adsorption between the first suction part 7 and the second suction part 8 can also improve the storage effect of the building air membrane 1. Moreover, the first suction part 7, the second suction part 8 and the third suction part 12 attract each other magnetically. When the monitoring sensor plate 6 deflects, the first suction part 7... Under the attraction of the first suction part 7 and the second suction part 8, the monitoring sensor plate 6 can be attached to the building air film 1. In order to improve the adhesion effect between the monitoring sensor plate 6 and the building air film 1, the monitoring sensor plate 6 is also provided with an arc-shaped part to provide the adhesion effect when the monitoring sensor plate 6 is attached to the building air film 1. Furthermore, the first suction part 7, the second suction part 8 or the third suction part 12 can also be set as an electromagnet. By controlling the magnitude of the current in the electromagnet, the sensitivity of the attraction between the first suction part 7, the second suction part 8 and the third suction part 12 can be controlled, making the device more adaptable.

[0036] like Figures 1-6 As shown, the sealing mechanism 5 includes a sealing mechanism body 10, a sensing pressure rod 11, a filling device 13, and a connecting plate 14. The sealing mechanism body 10 is fixedly connected to the lower end face of the structural reinforcing rib 2. The sensing pressure rod 11 is elastically embedded in the middle of the lower end face of the sealing mechanism body 10. The connecting plate 14 is fixedly connected to both sides of the lower end face of the sealing mechanism body 10. The filling device 13 is elastically connected between the two sets of connecting plates 14, and the sensing pressure rod 11 protrudes from the lower surface of the sealing mechanism body 10.

[0037] In use, the monitoring sensor plate 6 is fixedly connected to the filling device 13, thereby elastically connecting to the lower end face of the sealing mechanism 5. The monitoring sensor plate 6 is set perpendicular to the tangential direction of the building air membrane 1 by elasticity. When there is no damage, the monitoring sensor plate 6 neutralizes its own tilting gravity by elasticity, so that the monitoring sensor plate 6 and the building air membrane 1 maintain a stable vertical state. When the building air membrane 1 is damaged, because the monitoring sensor plate 6 is made of lightweight material, the contact surface between the monitoring sensor plate 6 and the airflow is large, which causes the monitoring sensor plate 6 to deflect. As the monitoring sensor plate 6 deflects, the distance between the third suction part 12 and the first suction part 7 and the second suction part 8 becomes closer, so that the monitoring sensor plate 6 finally adheres to the building air membrane 1 by magnetic adsorption, and temporarily seals it.

[0038] like Figures 1-7As shown, the filling device 13 includes a filling device body 15, a connecting shaft 16, an opening 17, a connecting shaft 18, and a limiting gear 19. The limiting gear 19 is rotatably embedded in the middle of the connecting plate 14 through the connecting shaft 16. The connecting shaft 18 is fixedly connected to the middle of the limiting gear 19. The filling device body 15 is elastically sleeved on the outer end face of the connecting shaft 18. The opening 17 is formed on the outer surface of the filling device body 15.

[0039] like Figures 1-8 As shown, a sealing cavity 21 is provided inside the main body 15 of the filling device. A partition is provided in the middle of the sealing cavity 21, and piston plates 20 are provided on both sides of the partition. A spiral spring 22 is embedded inside the main body 15 of the filling device. One end of the spiral spring 22 away from the main body 15 of the filling device is elastically connected to the connecting shaft 18. A screw groove 23 is provided at the contact point between the piston plate 20 and the connecting shaft 18. The sealing cavity 21 is connected to the opening 17, and the sealing cavity 21 is filled with sealant 24.

[0040] like Figures 1-10 As shown, the connecting plate 14 has a rotating groove 29 that is adapted to the limiting gear 19. The rotating groove 29 is connected to a spring groove 26. The spring groove 26 is elastically connected to a movable plate 27 through a spring 25.

[0041] like Figures 1-10 As shown, the end of the movable plate 27 away from the spring 25 is fixedly connected to a locking block 28 that engages with the limiting gear 19, and the movable plate 27 is fixedly connected to the sensing pressure rod 11.

[0042] In use, the filling device body 15 is elastically connected to the connecting shaft 18 via a spiral spring 22. Under the elastic action of the spring 25 on the movable plate 27, the limiting gear 19 is engaged by the locking block 28 to prevent rotation. The connecting shaft 18 is fixedly located in the middle of the limiting gear 19. The monitoring sensor plate 6 is fixedly connected to the side end face of the filling device body 15, thus providing elastic support to the filling device body 15 via the spiral spring 22. This ensures that the position of the monitoring sensor plate 6 is perpendicular to the building air membrane 1. When the monitoring sensor plate 6 deflects and adheres to the building air membrane 1... After closing, the internal elastic potential energy of the spiral spring 22 increases. When the monitoring sensor plate 6 rotates and presses against the sensing rod 11, the sensing rod 11 is pressed down by the adsorption force of the first suction part 7, the second suction part 8, and the third suction part 12. The sensing rod 11 is fixedly connected to the movable plate 27, thereby causing the movable plate 27 to move upward, causing the locking block 28 to disengage from the limiting gear 19. Then, the connecting shaft 18 rotates under the action of the internal elastic force of the spiral spring 22, thereby reducing the elastic support of the spiral spring 22 on the filling device body 15, so that the monitoring sensor plate 6 and the building air membrane 1... The fit is more precise, and when the connecting shaft 18 rotates, the main body 15 of the filling device is relatively fixed. A piston plate 20 is provided in the sealing cavity 21, and the piston plate 20 is provided with a screw groove 23. The side end face of the connecting shaft 18 is provided with a thread that matches the screw groove 23, and the thread is symmetrically arranged along the partition. This allows the piston plate 20 to move inside the sealing cavity 21 through the screw groove 23 when the connecting shaft 18 rotates, thereby squeezing the sealant 24 and causing it to spray out from the opening 17. This fills the gap between the building air membrane 1 and the monitoring sensor plate 6, as well as any damaged areas, effectively improving the sealing effect on the damaged areas. Under normal conditions, the opening 17 can be sealed with a thin film to prevent the sealant 24 inside from oxidizing or overflowing. The sealant 24 can also be filled with a corresponding color, making it easier for maintenance personnel to identify and repair the damaged areas after the piston plate 20 is triggered, greatly reducing the difficulty of maintenance and improving maintenance efficiency.

[0043] Working Principle: The inflation device 3 pressurizes the interior of the building air-supported membrane 1, ensuring a constant positive pressure. Multiple sets of structural reinforcing ribs 2 are horizontally arranged within the air-supported membrane 1, effectively improving its structural stability. A monitoring mechanism is also included to prevent damage from external forces or sharp objects, which could lead to a decrease in internal pressure and subsequent collapse, posing a safety hazard. A sealing mechanism 5 and a monitoring sensor 6 are included. The monitoring sensor 6 is elastically connected to the lower part of the sealing mechanism 5 and is perpendicular to the tangent of the air-supported membrane 1 under elastic force. When a rupture occurs on the surface of the air-supported membrane 1, the gas, under positive pressure, rapidly flows out through the rupture, causing the monitoring sensor 6 around the ruptured area to deflect due to the gas flow. The monitoring sensor 6 is monitored and its position is monitored. The amount of deflection indicates the leakage situation. Simultaneously, when the monitoring sensor plate 6 deflects, a first suction part 7 and a second suction part 8 are provided on the inner wall of the building air membrane 1. The first suction part 7 and the second suction part 8 pull the deflected monitoring sensor plate 6, causing it to deflect further and adhere to the building air membrane 1. By providing sealing structures such as sealing rings on the surface of the monitoring sensor plate 6, the damaged area can be effectively sealed temporarily after contact with the building air membrane 1, preventing further reduction of internal pressure and ensuring the stability of the building. Furthermore, after deflection, the monitoring sensor plate 6 adheres to the building air membrane 1. Once properly attached, the structure is easy to observe and facilitates warnings to personnel inside. Multiple monitoring mechanisms enable comprehensive monitoring of damage to the building's air-supported membrane 1. The lightweight materials used in these mechanisms enhance monitoring sensitivity while reducing the weight load on the air-supported membrane 1. To prevent the airflow at the damaged area from simultaneously deflecting adjacent monitoring sensors 6, causing interference between adjacent sensors 6, a limit baffle 9 is installed to restrict the rotation of the monitoring sensors 6, allowing them to deflect only in one direction. Under normal conditions, the monitoring sensors 6 are perpendicular to the tangent of the building's air-supported membrane 1 via an elastic element. When a damage occurs, the airflow pushes the monitoring sensors 6 to deflect unidirectionally and, under the action of the first suction part 7 and the second suction part 8, engages with the building's air-supported membrane 1. The air-supported membrane 1 is used to seal any damaged areas. The first suction part 7 and the second suction part 8 can be configured as flexible magnetic sheets embedded in the inner wall of the air-supported membrane 1. The cross arrangement of the first suction part 7 and the second suction part 8 can further enhance the structural strength of the air-supported membrane 1. At the same time, the use of flexible materials allows the air-supported membrane 1 to be stored more neatly. The adsorption between the first suction part 7 and the second suction part 8 can also improve the storage effect of the air-supported membrane 1. Furthermore, the first suction part 7, the second suction part 8, and the third suction part 12 attract each other magnetically. When the monitoring sensor plate 6 deflects, the monitoring sensor plate 6 can be attached to the air-supported membrane 1 under the attraction of the first suction part 7 and the second suction part 8. In order to improve the adhesion effect between the monitoring sensor plate 6 and the air-supported membrane 1,The monitoring sensor plate 6 is also provided with an arc-shaped portion to improve the adhesion between the monitoring sensor plate 6 and the building air membrane 1. Furthermore, the first suction part 7, the second suction part 8, or the third suction part 12 can be configured as an electromagnet. By controlling the magnitude of the current in the electromagnet, the sensitivity of the adhesion between the first suction part 7, the second suction part 8, and the third suction part 12 can be controlled, making the device more adaptable. The monitoring sensor plate 6 is fixedly connected to the filling device 13, thus elastically connected to the lower end face of the sealing mechanism 5. The monitoring sensor plate 6 is set perpendicular to the tangential direction of the building air membrane 1 by its elasticity. When no damage occurs, the monitoring sensor plate 6 neutralizes its own tilting gravity through its elasticity, ensuring that the monitoring sensor plate 6 and the building air membrane 1 are aligned. Maintaining a stable vertical state, when the building air membrane 1 is damaged, the monitoring sensor plate 6, made of lightweight material, has a large contact surface with the airflow, causing it to deflect. As the monitoring sensor plate 6 deflects, the distance between the third suction part 12, the first suction part 7, and the second suction part 8 decreases, resulting in magnetic adsorption that causes the monitoring sensor plate 6 to adhere to the building air membrane 1 for temporary sealing. The filling device body 15 is elastically connected to the connecting shaft 18 via a spiral spring 22. Under the elastic action of the spring 25 on the movable plate 27, the limiting gear 19 is engaged by the locking block 28 to prevent the limiting gear 19 from rotating. The connecting shaft 18 is fixedly located in the middle of the limiting gear 19. The monitoring sensor plate 6 is fixed to the side end face of the filling device body 15. The monitoring sensor plate 6 is fixedly connected to the building air membrane 15, thereby providing elastic support to the main body 15 of the filling device through the spiral spring 22. This allows the monitoring sensor plate 6 to be positioned perpendicularly to the building air membrane 1. When the monitoring sensor plate 6 deflects and adheres to the building air membrane 1, the elastic potential energy inside the spiral spring 22 increases. When the monitoring sensor plate 6 rotates and presses against the sensing rod 11, the sensing rod 11 is pressed down by the adsorption forces of the first suction part 7, the second suction part 8, and the third suction part 12. The sensing rod 11 is fixedly connected to the movable plate 27, thereby causing the movable plate 27 to move upward, causing the locking block 28 to disengage from the limiting gear 19. Subsequently, the connecting shaft 18 rotates under the action of the elastic force inside the spiral spring 22, thereby reducing the elastic support of the spiral spring 22 on the main body 15 of the filling device, allowing the monitoring sensor plate 6 to be perpendicular to the building air membrane 1. The fit is more precise, and while the connecting shaft 18 rotates, the filling device body 15 remains relatively fixed. A piston plate 20 is provided inside the sealing cavity 21, and the piston plate 20 has a screw groove 23. The side end face of the connecting shaft 18 has a thread that matches the screw groove 23, and the threads are symmetrically arranged along the partition. This allows the piston plate 20 to move inside the sealing cavity 21 via the screw groove 23 when the connecting shaft 18 rotates, thereby squeezing the sealant 24 and causing it to spray out from the opening 17. This fills the gaps and damaged areas between the building air membrane 1 and the monitoring sensor plate 6, effectively improving the sealing effect on damaged areas. Under normal conditions, the opening 17 can be sealed with a thin film to prevent the sealant 24 from oxidizing or overflowing.Furthermore, the sealant 24 can be filled with a corresponding color, facilitating the identification and repair of damaged areas by maintenance personnel after the piston plate 20 is triggered, greatly reducing maintenance difficulty and improving maintenance efficiency.
