Description

Technical Field

[0001] This utility model relates to the field of engineering monitoring technology, specifically, it is a high-temperature heat-insulating packaging device for a wireless inclinometer that can be used for early warning of building fires and collapses. Background Technology

[0002] With the development of smart buildings, structural health monitoring, and disaster early warning systems, wireless inclinometers, due to their compact structure, flexible installation, and remote communication capabilities, have been widely used for attitude monitoring of various structures such as bridges, slopes, multi-story buildings, and tunnels. In normal environments, wireless inclinometers operate stably. However, in extreme high-temperature environments such as building fires, metallurgical furnaces, or hot processing operations, their electronic components, battery modules, and wireless communication systems face severe challenges, easily leading to equipment failure due to overheating, signal attenuation, or module failure. In existing technologies, researchers mainly design protection for inclinometers from two aspects:

[0003] 1. Thermal protection:

[0004] Taking the utility model patent "A Cooling Device for Inclinometers for Measuring High-Temperature Objects" as an example, the patent's authorization announcement number is CN209263959U. It adopts a combination of a metal protective box and liquid nitrogen injection cooling to achieve short-term forced cooling of the inclinometer. This solution is suitable for angle measurement scenarios on hot workpiece surfaces.

[0005] Taking the utility model patent "A converter tilt protection shutdown device" as an example, the patent's authorization announcement number is CN218955759U. The tilt sensor is encapsulated in a metal equipment box with an air-cooling cylinder, and the internal temperature is reduced by natural or forced ventilation. This solution is applied to high-temperature industrial environments such as metallurgical furnaces.

[0006] 2. Wireless communication:

[0007] Most mainstream wireless monitoring systems currently use low-power long-range communication protocols such as LoRa. As shown in the utility model patent "A Real-time Health Monitoring System for Ancient Buildings Based on LoRa", an inclinometer, crack sensor, and temperature and humidity sensor constitute the data acquisition node. The data is sent to a remote gateway through a LoRa module, which is suitable for scenarios such as ancient buildings where power consumption requirements are high but data refresh frequency is low.

[0008] In recent years, some studies have gradually attempted to use WiFi modules for tilt data transmission, taking advantage of their high bandwidth, low latency, and fast short-distance transmission characteristics to serve structural monitoring applications with higher real-time requirements. However, such solutions have not yet been systematically integrated into high-temperature resistant wireless tilt meter protection systems, and there is a lack of precedents for integrated design with thermal protection materials.

[0009] Although existing technologies have made attempts in both thermal protection and wireless communication for inclinometers, the following significant technical bottlenecks still exist:

[0010] 1. Reliance on external cooling sources or ventilation conditions: Liquid nitrogen injection or air cooling solutions cannot be implemented or maintained at the fire scene, and their structure is complex and their applicability is poor;

[0011] 2. Lack of thermal protection against extreme thermal environments such as building fires: Existing systems do not integrate efficient and lightweight insulation materials, making it difficult to resist continuous high temperatures, thermal radiation, and smoke erosion;

[0012] 3. Large structural volume and low integration: Most are external enclosures or fixed installations, which are not suitable for rapid deployment or miniaturized sensor applications;

[0013] 4. Communication protocols are not suitable for the high-frequency transmission requirements of fire scenarios: Although long-distance communication protocols such as LoRa have low power consumption, they have narrow bandwidth, slow data updates, and high latency. They are difficult to respond in real time in sudden changes such as rapid local tilting or collapse of buildings. Although WiFi communication solutions have advantages such as high-frequency sampling, low latency, and flexible network construction, they are more suitable for short-term, high-intensity information collection scenarios such as fires. However, there are no mature products or patents that can be integrated with high-temperature resistant structures.

[0014] In summary, there is currently a lack of integrated wireless inclinometer protection devices that combine thermal protection and high-frequency communication capabilities for building fires and high-temperature emergencies. There is an urgent need to develop an integrated device that combines high-efficiency thermal insulation materials with a high-speed WiFi communication module to achieve reliable monitoring and real-time early warning in high-temperature environments. Utility Model Content

[0015] The purpose of this invention is to provide a high-temperature thermal insulation packaging device for a wireless inclinometer that can be used for early warning of building fire collapse. This device enables high-temperature thermal protection of the sensor, stable signal transmission, and rapid response to sudden fire situations, and has broad engineering applicability and promotional value.

[0016] The purpose of this utility model is achieved as follows: A high-temperature heat-insulating encapsulation device for a wireless inclinometer that can be used for early warning of building fires and collapses, comprising:

[0017] The outer shell that forms the sealed structure is fixedly installed on the steel component. Its outer layer is an outer skeleton with impact resistance and corrosion resistance, and its inner layer is a high temperature resistant plate.

[0018] A wireless inclinometer, housed inside the casing;

[0019] An insulating structure made of alumina ceramic fiber is positioned between the inner wall of the outer shell and the wireless inclinometer.

[0020] Furthermore, the heat insulation structure is composed of multiple layers of heat insulation panels bonded together from the outside to the inside.

[0021] Furthermore, the heat insulation structure has a rectangular placement space in the middle, and the wireless tilt meter is installed within the rectangular placement space.

[0022] Furthermore, the heat insulation board of the heat insulation structure is an alumina ceramic fiber board.

[0023] Furthermore, the outer shell is a rectangular box structure, and the heat insulation structure matches the internal space of the outer shell.

[0024] Furthermore, the outer frame of the outer shell is a stainless steel frame structure.

[0025] Furthermore, the high-temperature resistant plate is a high-temperature resistant phlogopite board.

[0026] Furthermore, the outer shell is fixedly connected to a mounting plate, which has several mounting holes and several fixing bolts corresponding to the mounting holes. The fixing bolts pass through the mounting holes and fix the steel components to the mounting plate to the surface of the steel components.

[0027] The beneficial effects of this utility model are as follows:

[0028] 1. Strong high-temperature adaptability and excellent thermal insulation capability: Utilizing multi-layer alumina ceramic fiber as the main thermal insulation material, this material has a low thermal conductivity (typically 0.08-0.15 W / m·K at high temperatures) and excellent thermal stability. It can maintain structural integrity in continuous high-temperature environments (up to 1200℃), effectively reducing the internal temperature rise rate of the device and helping to delay the thermal shock time of the wireless inclinometer. This provides a feasible thermal environment buffer for short-term attitude monitoring under fire conditions. Compared to bare sensors without any thermal protection, this structure is expected to significantly improve the sensor's survival time in high-temperature environments, providing important technical support for capturing critical response signals such as structural tilting and collapse during fires.

[0029] 2. This solution has a high degree of overall structural integration, flexible layout, and compact size. It supports bolt pre-embedded installation and is compatible with a variety of building components, especially key load-bearing components such as steel structure beams and columns. The integrated design can reduce on-site connection links and improve on-site installation efficiency and operational reliability. Attached Figure Description

[0034] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figure 1-3 As shown, a high-temperature heat-insulating encapsulation device for a wireless inclinometer that can be used for early warning of building fire collapse is proposed, comprising:

[0036] The outer shell 9, which constitutes the sealed structure, adopts a modular design and has good mechanical strength and fire resistance integrity. The outer shell 9 is fixedly installed on the steel component 7. Several parts of the outer shell 9 are assembled and fixed into a whole by self-tapping screws 4, thereby forming a sealed space, which is beneficial to protect the internal components. The outer layer of the outer shell 9 is set as an outer skeleton 2 with impact resistance and corrosion resistance, and its inner layer is set as a high temperature resistant plate 3. Preferably, the outer skeleton 2 of the outer shell 9 is a stainless steel skeleton structure, and the high temperature resistant plate 3 is a high temperature phlogopite board with good dielectric strength and thermal stability, which can be used as a high temperature insulation protective layer.

[0037] The wireless inclinometer 6, which has a built-in rechargeable lithium battery, is housed inside the casing 9. It supports real-time wireless data transmission based on the WiFi protocol and can connect to a local wireless router to upload data to an edge server or cloud platform. The wireless inclinometer 6 can be connected to a building fire monitoring platform, edge computing gateway, or fire control system to achieve rapid alarm and response based on changes in inclinometer angle.

[0038] A thermal insulation structure 5, made of alumina ceramic fiber, is filled between the inner wall of the outer shell 9 and the wireless inclinometer 6.

[0039] The heat insulation structure 5 is composed of multiple layers of heat insulation boards bonded together from the outside to the inside. Preferably, the heat insulation board of the heat insulation structure 5 is an alumina ceramic fiber board, which has excellent high temperature resistance and low thermal conductivity. The thickness of each layer of heat insulation board can be 5-10mm, and the layering design can be carried out according to the protection level. The alumina content of the heat insulation board of the heat insulation structure 5 is ≥72%, which can withstand continuous high temperature up to 1200-1400℃ and has excellent thermal stability and heat delay effect.

[0040] Due to the excellent high-temperature resistance of alumina ceramic fibers, which maintain thermal stability and mechanical strength in environments above 1200℃, and their low thermal conductivity (typically 0.08–0.15 W / m·K under high-temperature conditions), they can effectively block heat convection and heat radiation conduction in fire environments. By optimizing the fiber layer thickness and layout structure, this encapsulation system can significantly delay the transfer of heat to the core area of ​​the sensor and reduce the local temperature rise rate, thereby providing a longer-term thermal protection buffer for the wireless inclinometer 6 under high-temperature conditions such as building fires.

[0041] As a further improvement, the above-mentioned heat insulation structure 5 has a rectangular placement space in the middle, the wireless inclinometer 6 is installed in the rectangular placement space, and the outer shell 9 is a rectangular box structure in general, with the heat insulation structure 5 matching the internal space of the outer shell 9.

[0042] The aforementioned outer casing 9 is welded and fixed with a mounting plate 1. The mounting plate 1 has several mounting holes 1a (the specific number is not limited), and is also equipped with several fixing bolts 8 corresponding one-to-one with the mounting holes 1a. The fixing bolts 8 pass through the mounting holes 1a and fix the inserted steel component 7 to fix the mounting plate 1 to the surface of the steel component 7. During installation, the device can be reliably connected to typical components such as steel beams, steel columns, and support nodes through the fixing bolts 8, resulting in a firm installation and high fire resistance integrity.

[0043] The above solution has the following advantages:

[0044] 1. Strong adaptability to high temperatures and excellent thermal insulation capability;

[0045] This design employs multi-layered alumina ceramic fiber as the primary insulation material. This material possesses a low thermal conductivity (typically 0.08-0.15 W / m·K at high temperatures) and excellent thermal stability, enabling it to maintain structural integrity in sustained high-temperature environments (below 1200℃). Theoretical thermal conduction analysis indicates that, with appropriate insulation layer thickness and a reasonable encapsulation design, the internal temperature rise rate of the device can be effectively reduced, helping to delay the thermal shock time experienced by the wireless inclinometer 6 and providing a feasible thermal environment buffer for short-term attitude monitoring under fire conditions. Compared to bare sensors without any thermal protection, this structure is expected to significantly improve the sensor's survival time in high-temperature environments, providing crucial technical support for capturing critical response signals such as structural tilting and collapse during fires.

[0046] 2. This solution uses a wireless inclinometer 6 with a WiFi communication module, and the refresh rate can reach up to 100Hz. It is suitable for the high-frequency data requirements of sudden deformation in building fires. The WiFi signal channel and thermal protection layer are designed in tandem to maintain signal stability and low-latency transmission in high-temperature and smoke environments. Compared with LoRa's refresh rate of only 1-2Hz, the WiFi module can support ≥10Hz tilt refresh and data backhaul. Under fire conditions, the WiFi signal has a packet loss rate of less than 1% and a latency of <20ms within a 15-meter range, which is better than the typical transmission latency of LoRa (200-800ms). It is suitable for the sudden monitoring needs of severe structural deformation and can provide real-time basis for collapse early warning and fire-fighting decision-making.

[0047] 3. This solution features high structural integration, flexible layout, and compact size. It supports bolt pre-embedded installation and is compatible with various building components, especially key load-bearing components such as steel beams and columns. The integrated design reduces on-site connection links, improving on-site installation efficiency and operational reliability.

[0048] 4. This solution can be directly installed in key fire-prone locations such as high-rise buildings, underground stations, steel structure factories, and large-scale warehousing and logistics centers for structural safety monitoring; it has high productization capabilities, is easy to mass-produce and integrate for deployment, and is conducive to forming an integrated intelligent monitoring system of "structural safety-fire response"; it is of great significance for improving the perception of structural strain processes during fires, reducing disaster losses, and enhancing the disaster prevention and mitigation capabilities of buildings.
