Description

Technical Field

[0001] This invention relates to the field of engineering structure safety monitoring technology, and in particular to a wired inclinometer high-temperature fireproof protection integrated device. Background Technology

[0002] With the rapid development of structural health monitoring technology and intelligent disaster early warning systems, wired inclinometers have been widely used in displacement and tilt monitoring of various engineering structures such as bridges, slopes, multi-story buildings, and tunnels due to their advantages such as stable data transmission, strong anti-interference capabilities, and convenient installation. Under normal temperature or general outdoor conditions, these sensors can operate stably and provide reliable data for extended periods. However, in extreme high-temperature environments such as building fires, metallurgical furnace fires, tunnel fires, and hot processing areas, the sensitive electronic components inside the inclinometer are prone to rapid degradation and failure due to overheating caused by drastic temperature increases and enhanced thermal radiation. This can lead to system failure, severely impacting the reliability and timeliness of structural condition perception and early warning response.

[0003] Currently, there are limited means to ensure the operational stability of wired inclinometers in high-temperature environments. Existing protection solutions still face the following significant technical bottlenecks in practical applications:

[0004] 1. Reliance on external cooling sources or ventilation systems, resulting in poor adaptability. Some systems attempt to use external cooling methods such as liquid nitrogen injection, forced air cooling, or water cooling to reduce the sensor's operating temperature. However, these methods are often difficult to implement or maintain continuously in high-temperature emergency situations such as building fires. The systems are complex in structure, costly, and highly dependent on external cooling, which greatly reduces their practicality and scalability.

[0005] 2. Lack of thermal protection design for extreme high-temperature scenarios. Most existing products fail to integrate efficient thermal insulation structures and materials, especially in terms of dealing with multiple thermal hazards such as direct flame action, intense heat radiation, and high-temperature flue gas erosion, making it difficult to ensure the normal operation of the inclinometer and stable data transmission in continuous high-temperature environments.

[0006] 3. The protective devices are bulky and have low integration, which is not conducive to flexible deployment. Currently, most common high-temperature protection designs use external enclosures or heavy metal shells for protection. These are not only large and heavy, but also cumbersome to install. They cannot meet the needs of rapid response or sensor deployment in confined spaces, thus limiting the flexibility and adaptability of the system.

[0007] CN202220110968.X discloses a protective device for mounting a high-precision inclinometer, including a mounting base on which the inclinometer is fixed. The device further includes a protective cover, comprising a first cover and a second cover, which are fastened together to form an open-end structure. The first and second covers are positioned outside the inclinometer, and a cable outlet is provided on one side of the first cover. A sliding groove is provided on the mounting base, with one end extending to the end of the mounting base and communicating with the outside. Sliding rails are provided on the first and second covers to slide against the groove, allowing the first and second covers to be slidably connected to the mounting base. However, this device lacks sufficient high-temperature protection and has limited adaptability.

[0008] In summary, there is an urgent need to develop a wired inclinometer fire protection device that is compact, easy to install, has excellent thermal insulation performance, and possesses strong thermal protection capabilities, in order to ensure its long-term reliable operation in extreme high-temperature environments and improve the overall risk resistance and on-site adaptability of the structural disaster monitoring system. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-temperature fireproof integrated device for wired inclinometers, which has strong high-temperature adaptability, excellent thermal insulation performance, high structural integration, flexible installation and deployment, and adjustable performance design capabilities, making it highly adaptable.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] This invention provides a high-temperature resistant and fireproof integrated device for wired inclinometers, comprising:

[0012] An inclinometer, installed inside the device, is used to monitor the tilt angle of the structure in real time; the inclinometer is connected to an external analytical control platform via wires.

[0013] Insulation panels cover the inclinometer and form a thermal buffer zone;

[0014] The exoskeleton, as the overall support frame, is used to support and protect the entire device;

[0015] The outer partition is fixed to the outer frame to form a six-sided enclosed protective structure;

[0016] Mounting plates are welded to the outer frame and used to fix the device in place.

[0017] Furthermore, the conductors are nickel conductors, and there are four conductors: two for power supply and the other two for data transmission. Nickel conductors have a high melting point, high conductivity, oxidation resistance, and flame retardant properties.

[0018] To ensure stable signal transmission in high-temperature environments, high-purity Ni wire is selected for the conductors, which has the following core advantages:

[0019] (1) High melting point (over 1400℃), capable of withstanding significant temperature rise in fire environments.

[0020] (2) It has strong antioxidant properties and can form a dense NiO protective layer at temperatures below 800℃ to prevent further oxidation.

[0021] (3) Excellent flame retardancy, meeting the UL94 V-0 flame retardant rating standard.

[0022] (4) Excellent corrosion resistance, suitable for harsh environments such as acid, alkali, high humidity and sulfur.

[0023] (5) High strength and high toughness, resistant to mechanical impact, vibration and long-term bending.

[0024] (6) Good electromagnetic compatibility reduces the impact of external interference on signal quality and ensures high-fidelity acquisition and transmission of inclinometer data.

[0025] Furthermore, the conductor is externally covered with a quartz fiber insulating sleeve to prevent short circuits and leakage, and to improve electrical insulation safety in high-temperature environments.

[0026] To enhance the insulation and thermal protection capabilities of the conductors, each Ni conductor is externally wrapped with a high-performance quartz fiber insulating sleeve. Quartz fiber offers the following advantages:

[0027] (1) It has extremely high temperature resistance (long-term operating temperature 800-1000℃, melting point up to 1700℃) and can maintain insulation stability under extreme temperature changes such as fire.

[0028] (2) It has excellent electrical insulation properties, high dielectric strength and volume resistivity, ensuring that there is no risk of signal leakage at high temperatures.

[0029] (3) Non-flammable, smokeless, and corrosion-resistant, suitable for various high-risk industrial environments.

[0030] (4) It has strong flexibility and can adapt to the wiring in narrow spaces. It also has good thermal expansion matching with Ni wire, avoiding the insulation layer from cracking due to thermal stress.

[0031] Furthermore, the insulation board is a multi-layer aerogel insulation layer or an aluminum silicate fiber board, which has low thermal conductivity and high temperature resistance. The thickness and number of layers of the insulation board can be adjusted according to the actual environment. Using aerogel board as the insulation layer provides excellent high-temperature resistance (long-term temperature resistance can reach over 1000℃) and extremely low thermal conductivity, ensuring controlled temperature rise inside the device. The material supports a layered composite structure design, with each layer being 5-10mm thick, which can be flexibly stacked and adjusted according to the actual application scenario to adapt to different levels of fire heat exposure.

[0032] Furthermore, the outer frame is a stainless steel keel outer frame, which has high strength and corrosion resistance.

[0033] Furthermore, the mounting plate is provided with multiple bolt holes for fixing the device to steel beams, steel columns or other load-bearing components by bolts.

[0034] Furthermore, the outer partition is a high-temperature resistant mica board with a six-sided closed structure. The mother board has excellent dielectric strength, thermal stability, and heat radiation shielding ability, which can effectively prevent high-temperature heat flow and flames from directly corroding the internal sensitive components, forming the first thermal protection barrier.

[0035] Furthermore, the outer partition is fixed to the outer frame using U-shaped clamps and stainless steel screws. The U-shaped clamps span the outer frame frame and are connected to the outer partition via stainless steel screws, forming a stable and sealed protective structure. Each U-shaped clamp spans both sides of the outer frame, conforms to the outer frame contour, and is fastened to the outer partition using stainless steel self-tapping screws through pre-set screw holes, forming a stable and secure clamping structure.

[0036] Furthermore, the wires are arranged in multiple loops inside the device to extend the heat conduction path, reduce the heat flux density, and slow down the rate at which heat is transferred to the inclinometer.

[0037] The heat transfer to the inclinometer within the device mainly occurs through two paths: first, external thermal radiation or conduction through the insulation layer; second, heat is conducted along the Ni wires to the inclinometer body. To suppress the latter's thermal conductivity effect, this invention optimizes the arrangement of the wires within the device, arranging the Ni wires in a multi-segment winding path. This effectively extends the heat flow path, reduces the heat flux density per unit length of wire, and thus significantly slows down the heat transfer rate. This design effectively reduces the heat input from the wires to the core sensor components, further improving the inclinometer's thermal stability and resistance to thermal shock in high-temperature environments.

[0038] Furthermore, the outer frame is made of square or rectangular profiles, which have impact resistance, corrosion resistance, and high-temperature stability. It can maintain structural integrity and remain undeformed in extreme environments such as fire, explosion, and heat treatment.

[0039] This invention employs a modular, integrated packaging structure, which not only possesses high strength and excellent protective capabilities but also supports mass production and standardized deployment. After assembly, the outer frame, sleeve, and mica plate together form a multi-layered, sealed thermal protection shell, offering advantages such as high structural rigidity, excellent airtightness, long-lasting high-temperature resistance, and secure insulation. This effectively protects critical components inside the device, such as the inclinometer, wires, and insulation layer, ensuring stable operation in extreme thermal environments such as fires. The device allows for flexible configuration of the insulation board's material, thickness, and layering structure according to actual operating conditions, and the internal wiring path and length can be adjusted to achieve a customized match between thermal protection capabilities and structural integration.

[0040] To adapt to complex on-site conditions and improve installation efficiency, this invention designs a universal pre-embedded installation structure: a high-strength stainless steel mounting plate is welded onto a stainless steel outer frame structure, and the plate is customized in size according to the usage scenario; four standard bolt holes are set on the top and bottom of the plate surface to facilitate reliable connection between the device and target components (such as steel beams, columns, and support nodes); it supports rapid deployment by a single person, does not rely on large construction tools, and maintains excellent fire integrity and mechanical stability.

[0041] This invention proposes a highly integrated, heat-insulating, and multi-layered synergistic protection wired inclinometer fire protection device for high-temperature extreme environments. It significantly improves the functional stability, safety, and environmental adaptability of inclinometers under extreme conditions such as fires, and has broad application prospects and good industrialization promotion value.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] (1) Strong adaptability to high temperatures and excellent thermal insulation performance. This invention uses multilayer aerogel as the main thermal insulation material. The thermal conductivity of this material at high temperatures is approximately 0.02-0.1 W / (m·K), which is much lower than that of traditional materials such as mineral wool and aluminum silicate fiber, and it has extremely excellent thermal insulation ability and thermal stability. By optimizing the design of the thermal insulation layer thickness and the encapsulation structure layout, the structural integrity and internal functional stability of the device can be maintained for a long time in environments with temperatures up to 1200℃.

[0044] Thermal analysis results show that this multi-layer insulation system can significantly reduce the internal temperature rise rate of the device, forming an effective thermal buffer space. This helps to delay the time window for thermal shock to the internal components of the inclinometer, supporting its completion of critical structural attitude monitoring tasks under sudden high-temperature conditions such as fires. Compared with bare inclinometer sensors without any thermal protection, this invention can significantly improve the device's "high-temperature survival time" and functional retention rate, providing reliable data support for the timely identification and early warning of building structural tilt, local buckling, or overall collapse. Simultaneously, the use of pure Ni wire further enhances the overall thermal protection performance, maintaining excellent conductivity and oxidation resistance even in high-temperature environments, ensuring a stable and reliable data transmission link and providing a robust physical channel guarantee for disaster monitoring systems.

[0045] (2) High structural integration and flexible installation and deployment. The device has a compact overall structure and small size. All heat insulation, protection, support, and installation components are integrated into one unit, eliminating the need for additional external equipment or cooling systems. It supports bolt-embedded installation, which can be quickly and firmly fixed to the surfaces of various key components such as steel beams, steel columns, and connection nodes. It has strong adaptability and is especially suitable for confined or restricted scenarios such as high-rise buildings, large-span factories, and underground spaces. The integrated device reduces system connection interfaces, lowers the complexity of on-site construction and potential failure points, and helps improve construction efficiency and long-term reliability of device operation, laying the foundation for the large-scale deployment of intelligent monitoring systems in the future.

[0046] (3) It possesses adjustable performance-based design capabilities and is highly adaptable. This invention provides the ability to customize designs according to environmental requirements. Based on actual operating conditions such as fire severity, target location exposure temperature, and monitoring cycle, the thickness of the aerogel insulation layer can be flexibly adjusted, or the internal path layout of the Ni conductors can be optimized, balancing thermal protection effectiveness with cost control to achieve the optimal balance between economy and adaptability. This performance-adjustable design framework enhances the device's ability to be deployed in multiple scenarios, meeting the personalized protection needs of different building types and usage conditions.

[0047] (4) Significant social benefits and engineering application value. This invention can be widely applied to high-risk fire locations such as high-rise buildings, underground stations, steel structure factories, large-scale warehousing and logistics centers, power tunnels, and bridges, significantly improving the real-time response and early warning capabilities of structures during fire development. It possesses excellent productization capabilities and manufacturing adaptability, enabling standardized mass production and easy integration into structural monitoring systems to construct an integrated solution of "structural safety monitoring – intelligent fire response." By accurately capturing structural deformation and tilting trends during a fire, this invention helps to promptly identify potential local instability hazards or precursors to overall failure, reducing casualties, minimizing property damage, and enhancing the disaster resistance of building systems, thus possessing significant social safety value and promising prospects for widespread application.

[0081] (1) It has extremely high temperature resistance (long-term operating temperature 800-1000℃, melting point up to 1700℃) and can maintain insulation stability under extreme temperature changes such as fire.
