[0032] In conjunction with Figures 1 to 4 As shown, according to the specific embodiment of the present application, a modular intelligent thermal warm shed system is provided.

[0033] Specifically, as shown in Figure 1 , Figure 4 A modular intelligent thermal warm shed system includes a frame assembly 10, the frame assembly 10 has a plurality of frame units 11, the frame assembly 10 is arranged in a cold region tunnel 100; a composite thermal insulation layer 20, the composite thermal insulation layer 20 is located on the outer surface of the frame assembly 10, the frame assembly 10 and the composite thermal insulation layer 20 form a protective space with an opening; a temperature control assembly 30, the temperature control assembly 30 is arranged in the protective space, and the temperature control assembly 30 is used for controlling the temperature in the protective space.

[0034] In this embodiment, by arranging the frame assembly 10 composed of a plurality of frame units 11, the composite thermal insulation layer 20 is arranged on the outer surface of the frame assembly 10, the frame assembly 10 has a supporting effect, the composite thermal insulation layer enhances the thermal insulation performance compared with a single layer of thermal insulation material, and can also improve the mechanical strength and durability, by arranging the temperature control assembly 30 in the protective space, the heat can be accurately controlled, the problem of temperature over-regulation or insufficient in the conventional warm method is avoided, the waste of energy is reduced, and at the same time, the automatic operation can be realized, the dependence on manual labor is reduced, and the problems of large heat loss of the tunnel in winter and high cost of manual temperature control in the prior art are solved.

[0035] As shown in Figure 2 , the plurality of frame units 11 can be spliced, and the connection between two frame units 11 is provided with a hydraulic fastener.

[0036] Specifically, the frame unit 11 is made of a lightweight aluminum alloy unit, which is a 500mm×500mm standard module. The nodes are spliced using a mortise and tenon process, and fixed using a hydraulic fastener, thereby realizing the rapid assembly of multiple frame units 11, greatly shortening the erection time of the warm shed and improving the construction efficiency. The hydraulic fastener is a device that uses hydraulic principle to perform fastening operation.

[0037] Further, the inner surface of each frame unit 11 is provided with a heat reflecting layer made of an aluminum foil composite film.

[0038] Specifically, as a high-reflectivity metal material, the aluminum foil can effectively reflect heat and reduce heat loss through thermal radiation. In the modular intelligent heat preservation warm shed system, the presence of the heat reflecting layer can reflect most of the infrared and other thermal radiation energy back into the protected space, reducing the speed of heat loss from the warm shed to the outside, thereby improving the heat preservation efficiency.

[0039] As shown in Figure 4 , the temperature control assembly 30 includes: a sensor unit 31, the sensor unit 31 being located in the protected space, the sensor unit 31 being used to collect temperature information and humidity information in the protected space; a heating unit 32, the heating unit 32 being located in the cold region tunnel 100, the heating unit 32 being used to heat the protected space; a controller 33, the controller 33 being electrically connected with the sensor unit 31 and the heating unit 32, the controller 33 being based on the temperature information and the humidity information and using a fuzzy PID algorithm to adjust the temperature of the heating unit 32.

[0040] Specifically, the sensor unit 31 can continuously collect temperature and humidity information in the protected space. These data are transmitted to the controller 33 in real time, so that the system can respond to the environmental changes in the protected space in real time. The sensor unit 31 can monitor the temperature changes in the protected space in real time, and rapidly respond through the controller 33 using intelligent algorithms (such as fuzzy PID control) to adjust the power output of the heating unit 32, thereby maintaining the temperature of the protected space within the preset range and ensuring the high stability of the temperature.

[0041] As shown in Figure 4 , the heating unit 32 further includes: an infrared radiation plate 321, the infrared radiation plate 321 being electrically connected with the controller 33, the controller 33 being based on the temperature information and the humidity information and using a fuzzy PID algorithm to adjust the power density of the infrared radiation plate 321.

[0042] Specifically, the infrared radiation plate 321 can directly transfer heat energy to the objects in the protection space in the form of infrared radiation. This heating method has good penetration for the objects and can quickly and uniformly raise the ambient temperature. The controller 33 adopts a fuzzy PID algorithm and can accurately calculate the required heating power according to the real-time collected temperature and humidity information, so as to accurately adjust the power density of the infrared radiation plate 321 and ensure that the temperature in the protection space is stably within the set range with a small error range, thereby effectively improving the accuracy of temperature control. The fuzzy PID algorithm can consider the influence of humidity on temperature control. When the humidity in the protection space changes, the algorithm will automatically adjust the heating strategy to ensure that the temperature adjustment is not disturbed by the change in humidity, thereby realizing the stability and adaptability of temperature control under different humidity conditions.

[0043] Further, the heating unit 32 further comprises: a floor heating pipe 322, the floor heating pipe 322 being arranged in the cold region tunnel 100, a water temperature sensor being arranged in the floor heating pipe 322, the water temperature sensor being configured to detect water temperature information in the floor heating pipe, the water temperature sensor being electrically connected to the controller 33, and the controller 33 being configured to control the water temperature and flow rate of the floor heating pipe 322 based on the temperature information, the humidity information and the water temperature information by using a fuzzy PID algorithm, so that the water temperature adjustment range is 30-60°C and the return water waste heat recovery rate is greater than or equal to 75%.

[0044] Specifically, the floor heating pipe 322 is laid along the tunnel floor, and its heating method is to radiate heat energy upward from the bottom of the ground, which can provide uniform and lasting heating effect and avoid the problems of local overheating or uneven heating. The water temperature sensor and the controller 33 form a closed-loop control circuit, which can feedback the water temperature information in the floor heating pipe in real time, and the controller can dynamically adjust according to the fuzzy PID algorithm to ensure that the water temperature in the pipe is stably in the optimal interval. This accurate control helps to maintain the consistency of the overall ambient temperature in the tunnel and avoids temperature instability caused by water temperature fluctuations.

[0045] Further, the modular intelligent heat preservation shed system further comprises a safety protection assembly, the safety protection assembly comprising: a combustible gas detector, the combustible gas detector being configured to detect the concentration of combustible gas in the protection space; a structural stress detector, the structural stress detector being configured to detect the structural stress of each frame unit 11; and an alarm unit, the alarm unit being electrically connected to the combustible gas detector and the structural stress detector, and the alarm unit being configured to issue an alarm.

[0046] Specifically, the combustible gas detector can monitor the concentration of combustible gas (such as methane, carbon monoxide, etc.) in the protective space in real time. Once the concentration exceeds the preset safety threshold, the alarm unit is triggered immediately to remind the operator to take emergency measures, such as starting the exhaust system, closing the fire source, and ensuring the safety of the tunnel construction. The structural stress detector is used to monitor the structural stress of each frame unit 11 in real time, which is crucial for preventing structural deformation or damage caused by wind and snow load, thermal expansion and contraction, etc. Through continuous monitoring, the system can provide early warning and take reinforcement measures to avoid sudden failure of the overall structure of the warm shed system.

[0047] wherein the detection limit of the combustible gas detector is ≤0.5ppm, the wind speed of the exhaust system is ≥5m / s; there is one structural stress monitoring point per 5㎡, and the early warning threshold is set to 80% of the frame safety load.

[0048] As shown in Figure 1 , Figure 3 , the composite insulation layer 20 includes: an outer layer 21 made of aerogel felt; an intermediate layer 22 configured as a vacuum insulated panel; and an inner layer 23 made of phase change material.

[0049] Specifically, the outer layer 21 is composed of aerogel felt, which has ultra-low thermal conductivity (about 0.018W / m·K), much lower than conventional insulation materials, which can effectively insulate external cold and heat sources and reduce direct conduction heat loss; the intermediate layer 22 uses a vacuum insulated panel (VIP panel), which greatly suppresses the convective heat transfer effect of gas molecules by encapsulating insulation materials under high vacuum conditions, with a thermal conductivity as low as about 0.007W / m·K, further improving the insulation performance of the insulation layer and reducing heat loss caused by air convection; the inner layer 23 is composed of phase change material (PCM), such as paraffin-based composite material (melting point about 5℃, phase change latent heat up to 220kJ / kg). Phase change material can absorb or release a large amount of latent heat when the temperature changes, effectively stabilizing the temperature fluctuations in the protective space through the phase change process from solid to liquid or vice versa, ensuring the optimal temperature conditions for the construction environment.

[0050] wherein the thermal conductivity of the outer layer 21 is a, a≤0.018W / m·K, the thermal conductivity of the intermediate layer 22 is b, b≤0.007W / m·K, the melting point of the inner layer 23 is c, 4.5≤c≤5.5℃, and the latent heat is d, d≥220kJ / kg.

[0051] Further, the thickness of the outer layer 21 is d1, and the thickness of the intermediate layer 22 is d2, wherein 9.5mm≤d1≤10.5mm, 19.5mm≤d2≤20.5mm.

[0052] Specifically, d1 and d2 are controlled in the above range, which can ensure that the heat preservation performance of the material reaches the best state. The thickness of the aerogel blanket and the vacuum insulation board directly affects the thermal resistance, and too thick or too thin can reduce the heat insulation efficiency of the material.

[0053] Further, the frame assembly 10 is provided with a blocking assembly on one side of the opening of the cold region tunnel 100, the blocking assembly is inflatable, and a magnetic sealing rubber strip is arranged along the inner circumferential surface of the opening of the cold region tunnel 100; when the blocking assembly is in an inflated state, the blocking assembly is connected with the magnetic sealing rubber strip.

[0054] Specifically, the blocking assembly is inflated to tightly fit the opening structure, and the use of the magnetic sealing rubber strip can increase the fitting degree of the blocking assembly and the edge of the opening, thereby forming a double sealing effect of magnetic adsorption. This design can significantly improve the isolation of the protection space and the external environment, effectively reduce the heat loss, and ensure the heat preservation effect.

[0055] In an optional embodiment, the blocking assembly is an air bag made of high-strength and low-temperature-resistant TPU (thermoplastic polyurethane) or PVC (polyvinyl chloride) material.

[0056] In another optional embodiment, the blocking assembly is designed as a foldable inflatable curtain made of waterproof, windproof and low-temperature-resistant synthetic fabric material such as nylon or polyamide fabric, and the inside is filled with inflatable air chambers. The magnetic sealing rubber strip is distributed along the edge of the curtain.

[0057] In another embodiment of the present application, the modular frame is pre-assembled outside the opening, and the whole is positioned by a track sliding system (positioning error ≤ 3mm); the aerogel blanket, the vacuum insulation board and the phase change material layer are laid in layers, and the polyurethane foam adhesive is used for sealing at the joint; the temperature control system and the safety module are connected and debugged to realize the temperature uniformity error ≤ ± 1.5℃ and the automatic risk early warning.

[0058] According to another aspect of the present application, a use method of the modular intelligent heat preservation warm shed system is provided, and the use method of the modular intelligent heat preservation warm shed system is implemented as follows:

[0059] The first step is frame installation: 20 modules (total size 10m*4m*3m) are pre-assembled, and are positioned by a track sliding system (positioning error ≤ 3mm);

[0060] The second step is heat preservation layer construction: the aerogel blanket (the joint is staggered by 50mm), the VIP board (the joint is sealed by polyurethane foam adhesive), and the PCM layer (covered with polyethylene isolation film) are laid in sequence;

[0061] The third step is system debugging: the temperature control target is set to 5℃, and the power of the infrared radiation plate is automatically adjusted to 150W / m 2The water temperature of the floor heating maintains 45 DEG C, and the backwater waste heat is used for heating fresh air;

[0062] The fourth step, acceptance index: the average temperature in the shed is 6.8 DEG C, the maximum temperature difference is ±1.2 DEG C; the 7-day compressive strength of the concrete reaches 78% of the design value, and the 28-day strength exceeds the design value by 15%.

[0063] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:
