Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and in particular relates to an adaptive mobile house with temperature-controlled lifting and rotation. Background Technology

[0002] In the field of construction engineering, temporary buildings serve as key facilities for on-site offices and residences, disaster relief and resettlement, and outdoor work sites. Their environmental adaptability, living comfort, and energy efficiency directly impact user experience and operational efficiency. Among these, prefabricated modular houses are widely used in various temporary scenarios due to their modular prefabrication, rapid assembly, and relocation and reuse capabilities. However, current technologies for temporary buildings still face multi-dimensional technical bottlenecks, making it difficult to meet the dynamic adaptation needs of complex environments.

[0003] From the perspective of thermal environment control, the existing temporary building envelope design has significant defects. In high-temperature summer environments, solar radiation directly enters the interior through the walls, roof, and other envelope structures. Traditional container houses often use single lightweight materials for their walls, resulting in insufficient insulation and high thermal conductivity (the thermal conductivity of ordinary steel plates or color steel plates can reach over 50 W / m·K). This leads to rapid heat conduction into the interior, causing the indoor temperature to be significantly higher than the ambient temperature for a short period, with temperature differences exceeding 10°C in some scenarios. Simultaneously, most temporary buildings lack dynamic shading mechanisms, and the exterior walls are mostly fixed and enclosed structures, allowing solar radiation to directly act on the building surface, further exacerbating indoor heat accumulation. The bottom support structure is often a fixed-height, elevated design, which, while providing moisture protection, fails to create an effective ventilation layer. Hot air accumulates indoors and is difficult to expel, necessitating forced cooling with air conditioning, leading to a surge in energy consumption. The average daily electricity consumption per unit area can reach 5-8 kWh, resulting in significant carbon emissions.

[0004] In low-temperature winter conditions, the shortcomings of existing temporary buildings in terms of thermal insulation performance become even more apparent. On the one hand, insufficient thickness of the insulation layer in the building envelope or the high thermal conductivity of the material (traditional foam insulation has a thermal conductivity of approximately 0.04 W / m·K, which is insufficient to effectively block heat loss) causes indoor heat to be rapidly conducted to the outside through the walls and roof. On the other hand, the open structure at the bottom creates air convection channels, allowing cold air to seep into the room through the gaps at the bottom, forming convective heat exchange with the warm indoor air, accelerating heat loss. This results in the indoor temperature being only 3-5°C higher than the ambient temperature, requiring continuous operation of heating equipment (electric heaters, oil heaters, etc.) to maintain the temperature. This not only consumes a lot of energy (average daily electricity consumption can reach 8-12 kWh in winter) but also poses safety hazards such as carbon monoxide poisoning. In addition, although some temporary buildings have added insulation layers, the lack of dynamic adjustment capabilities makes them an obstacle to heat insulation in summer, creating a contradiction of "not insulating in winter and not heat-insulating in summer."

[0005] In terms of adaptive adjustment capabilities, the structures and systems of existing temporary buildings are mostly fixed designs, unable to dynamically respond to environmental parameters. The bottom support height is fixed, making it impossible to adjust the height of the elevated floor according to the season or diurnal temperature difference to adapt to ventilation and insulation needs; the external wall shading is mostly manually removable sunshade panels, requiring manual operation, resulting in a delayed response and difficulty in accurately matching changes in solar radiation intensity; the ventilation system is mostly fixed fans or natural vents, lacking linkage control with temperature and humidity, making it unable to efficiently introduce cool air and expel hot air in summer, and causing heat loss in winter due to improper closure of vents.

[0006] In terms of energy utilization, existing temporary buildings have low integration with renewable energy sources. Although some buildings are equipped with solar photovoltaic panels, most are installed at fixed angles, which cannot provide both shading and power generation in summer, and it is also difficult to maximize the reception of solar radiation in winter. The photovoltaic panels lack linkage with the building's temperature control system, and the generated electricity is only used for basic lighting and does not participate in core temperature control processes such as ventilation and heating, resulting in low energy utilization efficiency. They still rely on traditional power grids for power supply, and their applicability is limited in outdoor scenarios without grid coverage.

[0007] Furthermore, existing temporary buildings lack modularity and stability. Synchronous control of the supporting structure is lacking, with many relying on simple mechanical supports, which can lead to uneven stress at the corners during lifting and lowering, causing the building to tilt. The connection between the exterior wall modules and the main structure lacks standardized design, making disassembly and maintenance difficult and hindering rapid configuration adjustments for different scenarios.

[0008] In summary, existing temporary buildings face multiple technical bottlenecks in areas such as thermal environment control, adaptive adjustment, energy utilization, structural stability, and modular adaptability, failing to meet the demands for living comfort, energy efficiency, and ease of operation in complex environments. Therefore, developing an adaptive temporary building capable of dynamically adjusting support height, shading and ventilation based on ambient temperature, and integrating renewable energy utilization, is crucial for solving these problems. Summary of the Invention

[0009] This invention provides a temperature-controlled adaptive temporary building support device to overcome the shortcomings of existing technologies and achieve intelligent switching between winter insulation and summer ventilation. The technical solution to the above-mentioned technical problems is as follows:

[0010] An adaptive mobile house with temperature-controlled lifting and rotation includes a house body, a paraffin-based thermal expansion drive system, an external wall thermal bimetallic louver curtain wall system, an intelligent control system, and a solar photovoltaic and ventilation integrated system. The intelligent control system incorporates a multi-physics coupling correction module, achieving cross-system collaborative control through the following original mechanism:

[0011] The temperature field distribution of the paraffin-based thermal expansion actuator, the stress and strain data of the external wall louver curtain wall, and the photoelectric conversion efficiency of the photovoltaic panel are collected in real time. A multi-physics coupling equation of "temperature-mechanics-photoelectric" is established to generate dynamic correction coefficients. The correction coefficient K = α·temperature gradient + β·strain value + γ·photoelectric conversion efficiency, where α, β, and γ are dynamic weights based on machine learning, and the action parameters of each system are adjusted in real time.

[0012] The paraffin-based thermal expansion drive system adopts a dynamic stiffness adaptive structure. The inner wall of the wax cylinder is provided with an annular magnetorheological fluid jacket. The intelligent control system monitors the changes in building load in real time through attitude sensors, adjusts the magnetic field strength of the jacket, changes the stiffness of the magnetorheological fluid, and realizes real-time matching of the extension and contraction resistance of the actuator.

[0013] The external wall thermal bimetallic louver curtain wall system integrates a thermoelectric co-drive unit, embedding a flexible thermoelectric generator at the connection between the bimetallic sheet and the frame, which directly converts the temperature difference of the louvers into electrical energy to power its own motor drive, forming a self-powered closed loop of "temperature difference → electrical energy → active regulation".

[0014] The intelligent control system achieves a 40% improvement in the accuracy of its proactive response to environmental parameters and a 30% reduction in system energy consumption through a three-layer innovative mechanism of "multi-physics field coupling correction + dynamic stiffness adaptation + thermoelectric self-powering synergy".

[0015] As a preferred technical solution, the specific workflow of the multiphysics coupling correction module is as follows:

[0016] 1) Real-time acquisition of three types of physical field data: temperature gradient, structural stress, and solar irradiance;

[0017] 2) By dynamically allocating the weights of the input layer of the attention mechanism neural network, the three types of data are fused, and the output includes control instructions with time lag compensation;

[0018] 3) When the instruction is executed, the real-time status of each system is synchronously fed back, including but not limited to parameters such as driver displacement deviation and louver angle error, and the weight coefficients of the coupling equation are corrected in reverse to form a self-learning closed loop.

[0019] As a preferred technical solution, the intelligent control system collects continuous temperature field distribution data in real time by arranging a distributed fiber optic temperature sensor array along the thickness direction of the bottom rock wool layer and the building floor slab. Specifically:

[0020] 1) Fiber optic sensors are continuously distributed along the thickness direction to generate a continuous temperature-depth curve, and the instantaneous temperature gradient is calculated by the slope of the curve;

[0021] 2) The intelligent control system combines the unsteady heat transfer correction coefficient of the bottom rock wool layer and the base plate material to continuously accumulate and dynamically correct the above temperature gradient data, and obtain the heat transfer intensity per unit area.

[0022] 3) The system evaluates the thermal insulation effect based on the coupling relationship between heat transfer intensity and ambient humidity: When the insulation is enhanced in winter, the paraffin-based thermal expansion actuator is controlled to contract so that the bottom of the house is close to the rock wool layer; in summer when the humidity is high, even if the heat transfer intensity does not reach the threshold, the actuator is controlled in advance to lift the house to form an air-ventilated layer, which, together with the heat insulation properties of the rock wool layer, reduces indoor heat exchange.

[0023] As a preferred technical solution, the intelligent control system deploys temperature sensing components on the building's exterior surface and in the surrounding air environment to collect real-time data on the building's surface temperature and ambient air temperature, and continuously calculates the temperature difference between the two.

[0024] The system continuously accumulates and calculates the temperature difference over time, and combines the structural characteristics of the building's exterior surface and airflow parameters to generate a dynamic curve showing the change of heat exchange between the air and the building surface per unit time over time.

[0025] In summer ventilation mode, the system judges the convective heat transfer efficiency based on the dynamic curve and automatically adjusts the power of the forced ventilation fan and the opening angle of the air inlet and outlet: when the heat exchange is high, the fan power is increased to 80% and the air inlet opening angle is 60°; when the heat exchange decreases to the set range, the fan power is reduced, thereby improving the cooling efficiency by dynamically matching the convective heat transfer demand.

[0026] As a preferred technical solution, the intelligent control system performs time-based cumulative calculations on the solar radiation heat flux density absorbed per unit area of ​​the building's exterior surface, combines a dual-dimensional prediction model to predict the indoor heat accumulation trend, and proactively drives the exterior wall thermal bimetallic louver curtain wall module to adjust its angle. When the sunlight is strong, the shading is closed in time, and at the same time, the angle of the roof solar photovoltaic panel is adjusted in conjunction with the power generation-shading balance algorithm to optimize the angle of the photovoltaic panel.

[0027] As a preferred technical solution, the intelligent control system continuously calculates the change in radiative heat exchange between the building surface and the environment over time, analyzes the strength of the nighttime radiative cooling effect, and controls the opening status of the louvered curtain wall and the operation of the ventilation system accordingly. Specifically:

[0028] 1) The intelligent control system deploys high-precision temperature sensing devices on the building's exterior surface and surrounding environment. Based on the radiation characteristics of the building's surface materials, it continuously calculates the radiative heat exchange between the two by combining the collected surface temperature and ambient temperature.

[0029] 2) By analyzing the dynamic changes of the above-mentioned radiative heat exchange over time, the system determines the strength of the nighttime radiative cooling effect: when the radiative heat exchange is large and the indoor temperature is higher than the outdoor temperature, the louvered curtain wall is opened to a suitable angle to promote the dissipation of indoor hot air in conjunction with the ventilation system; when the radiative heat exchange is small and the indoor temperature is lower than the outdoor temperature, the louvered curtain wall is closed to maintain a stable indoor temperature.

[0030] As a preferred technical solution, the intelligent control system analyzes the rate of change of historical temperature data, combines current temperature parameters and a two-dimensional prediction model to predict and calculate the trend of indoor temperature change in the future, and triggers the switching command of the house operation mode in advance. The switching command includes pre-action compensation, so that each system and module completes the state stabilization adjustment before the temperature reaches the threshold, so that the indoor temperature is always within a comfortable range.

[0031] As a preferred technical solution, in the synchronous control of the paraffin-based thermal expansion actuator, the intelligent control system uses a high-precision displacement sensor installed at the connection between the piston rod and the guide housing of each actuator to collect the expansion and contraction displacement data of each actuator in real time. It incorporates a prediction-compensation dual closed-loop algorithm, specifically:

[0032] 1) The system processes the displacement data, calculates the instantaneous rate of change of displacement of each actuator over time, and captures the differences in the extension and retraction speeds of each actuator;

[0033] 2) Based on the above displacement change rate and combined with the thermal expansion hysteresis coefficient of paraffin material, predict the displacement deviation of each actuator in the next 5 minutes.

[0034] 3) By comparing the predicted displacement deviations of the four drives, the intelligent control system adjusts the power of the heating element of each drive: increases the heating power by 10% for drives with lagging expansion and contraction, and decreases the heating power by 15% for drives with leading expansion and contraction. When the displacement deviation is ≥1mm, the mechanical synchronization locking mechanism is triggered to temporarily fix the leading drive, gradually reducing the displacement deviation and maintaining the horizontal stability of the building structure.

[0035] As a preferred technical solution, in the angle adjustment of the solar photovoltaic panel, the intelligent control system incorporates a power generation-shading balance algorithm to calculate the power generation revenue coefficient and shading benefit coefficient of the photovoltaic panel. The weights of both are dynamically adjusted with the seasons. Combined with the dynamic changes in the solar altitude angle and azimuth angle, the optimal tilt angle of the photovoltaic panel at different times is calculated.

[0036] Furthermore, the building structure, through the coordinated operation of a paraffin-based thermal expansion drive system, an external wall thermal bimetallic louver curtain wall system, and a solar photovoltaic and ventilation integrated system, under the unified control of an intelligent control system, achieves dynamic linkage of building support height adjustment, external wall shading and ventilation control, photovoltaic panel angle adaptation, and ventilation system operation through real-time monitoring and spatiotemporal coupling cumulative analysis of temperature gradient, heat exchange temperature difference, solar irradiance, and displacement changes. This adapts to changes in ambient temperature, maintains a comfortable indoor temperature range, and ensures structural stability and efficient energy utilization.

[0037] The beneficial effects of adopting the above technical solution are as follows: This invention utilizes the synergistic operation of a paraffin-based thermal expansion drive system, an external wall thermal bimetallic louver curtain wall system, an intelligent control system, and a solar photovoltaic and ventilation integrated system. Combined with the monitoring and calculation of parameters such as temperature gradient and heat exchange temperature difference, it achieves dynamic control of building support height, shading ventilation, and photovoltaic angle, thereby improving indoor thermal comfort, reducing energy consumption, and enhancing the environmental adaptability and energy utilization efficiency of temporary buildings.

[0052] System collaborative operation principle

[0053] This technology achieves full-scene environmental adaptability through the intelligent linkage of four core systems. Taking typical summer conditions as an example, the intelligent control system collects temperature gradient data in real time through high-precision temperature sensors evenly distributed along the thickness of the bottom rock wool layer and the base plate. When the heat transfer intensity exceeds the threshold, the system triggers a paraffin-based thermal expansion actuator to lift the building, forming an elevated ventilation layer. Simultaneously, the external wall thermal bimetallic louver curtain wall module automatically closes the shading according to the solar irradiance, and adjusts the shading angle with the adjustable photovoltaic panels on the roof to reduce solar radiation heat entering the room. The forced ventilation fan starts simultaneously, introducing cool air through the air inlet, expelling it from the air outlet after heat exchange inside the room, achieving a three-stage cooling process of "shading-ventilation-heat insulation".

[0054] Basic operating mode

[0055] This temperature-controlled adaptive temporary building support system includes a building body 1, paraffin-based thermal expansion actuators 2 (wax motors), an intelligent control module, ventilation components, and photovoltaic regulation components. The building body 1 can be a prefabricated modular box structure, supported by four wax motor actuators 2 installed at the four corners of the building's base, creating a raised space between the building's floor and the ground. The wax motor actuators 2 lift the building off the ground, providing moisture protection and space for bottom ventilation. In summer mode, the actuators 2 raise the building to form a ventilated and insulated raised space; in winter mode, the actuators contract, bringing the bottom of the building close to the rock wool board 3, reducing or eliminating the raised space to improve insulation and airtightness.

[0056] The wax motor guide housing adopts a rigid metal cylindrical structure, with the piston rod slidingly fitted within the cylinder. To achieve dynamic sealing, a flexible sealing ring is installed between the piston rod and the guide cylinder, using a high-temperature resistant fluororubber O-ring or a wear-resistant corrugated diaphragm structure to ensure a seal is maintained during piston reciprocating motion. The sealing ring is installed between the end of the guide housing and the piston rod. This structure effectively prevents dust, mud, and rainwater from entering the wax chamber, effectively protecting the wax chamber and piston assembly from contamination. In summary, the wax motor has excellent outdoor protection performance, ensuring stable operation of the system in dusty and rainy environments.

[0057] In the initial state ( Figure 2 As shown in the left figure, the paraffin wax inside the wax motor is solid and relatively small in volume. The piston is in a retracted state, and the spherical support is close to the bottom of the cavity, with the house structure close to the ground. When ventilation is required or in response to ambient temperature rise, the built-in heater 4 is activated to heat the paraffin wax at a controlled temperature. As the temperature rises, the paraffin wax undergoes a phase change, changing from solid to liquid with significant volume expansion, pushing the piston upwards axially, thereby lifting the spherical support above and allowing the house to rise vertically. Figure 2(As shown in the right figure). The heater 4 has its power adjusted by the intelligent control module, and its lifting height can be adjusted according to the outdoor temperature, house posture, or system strategy. The thrust generated by expansion is stable and controllable, sufficient to support the weight of the house structure. During the cooling process, the volume of the solidified paraffin decreases, the piston slowly falls back under its own weight, the spherical support descends accordingly, and the house returns to its ground-hugging state. The paraffin actuator 2 can passively adapt to changes in ambient temperature, or it can be actively controlled by the start and stop of the electric heating element under the action of the intelligent control module, thereby precisely adjusting the house support height. To ensure the synchronicity of the lifting and lowering of the four corner support actuators, this invention adopts a cooperative control combined with mechanical adaptation: all wax motor actuators have the same structural parameters, and the four supports are subjected to thermal expansion and contraction almost simultaneously when the ambient temperature changes; in active control mode, the control module adjusts the heating power of each actuator according to the feedback from the displacement sensor of each support actuator or the information from the house posture sensor, so that the four corners lift and lower synchronously, ensuring that the house always remains level and stable. Since the actuators move slowly, even slight asynchrony will not cause impact, and mechanical locking or limit devices can be used during the lifting and lowering process to prevent individual supports from lagging and slipping. Each wax motor 2 is externally enclosed in a sealed guide housing, which encapsulates and protects the internal wax cylinder and transmission components, providing waterproofing, dustproofing, and improved weather resistance. Its key moving parts are manufactured using high and low temperature resistant and corrosion-resistant materials, ensuring long-term reliable operation of the device in harsh outdoor environments. The wax motor 2 is connected to the house base and foundation using a hinged support design. For example, a rigid spherical hinge support is installed between the top of the drive unit and the house's bottom beam, with a fixed base plate at the bottom. This connection method can accommodate uneven settlement or slight angular deviations in the foundation, providing additional cushioning and anti-tilting capabilities to the supporting structure, improving the overall structural safety and durability.

[0058] The present invention includes several sets of adaptive louvered curtain wall modules 5 made of thermal bimetallic material installed around the exterior walls of the building, serving as a dynamically adjustable sunshade and ventilation device. The louvered curtain wall modules utilize modular brackets, which are bolted to the side walls of the container house (or building). The brackets are made of rigid metal profiles, ensuring a robust and reliable structure. The brackets are equipped with an adjustable rotating shaft mechanism and a motor mounting base: the rotating shaft assembly allows adjustment of the overall tilt angle and installation angle of the louvers, enabling horizontal or vertical angle adjustment via adjustable couplings or eccentric adjusting screws; the motor mounting base secures the drive motor and reliably connects to the drive shaft (transmission shaft). Through this design, the louvered curtain wall modules are firmly connected to the wall, capable of withstanding external forces such as wind loads, while allowing for fine-tuning of the angle offline (or on-site) as needed. The overall structure ensures both installation stability and flexibility in adjusting the louver opening and closing angle, facilitating subsequent maintenance and tilt angle optimization. In this invention, a bimetallic combination of Invar (iron-nickel alloy) and brass is preferably used. The heat-absorbing coating is preferably applied to the surface of the brass layer to allow solar radiation energy to be absorbed more efficiently by the side with the higher coefficient of thermal expansion, thereby improving the susceptibility of the louvers to temperature changes and the shading effect. Invar alloy has an extremely low coefficient of thermal expansion, while brass has a relatively high coefficient of thermal expansion. When combined, they can achieve significant bending displacement when heated. When there is strong direct sunlight, the louvers are heated unevenly, causing bending deformation. Because the blackened side expands more significantly when heated, the louvers bend and droop towards that side, thereby changing the louver angle and automatically closing the louvered curtain wall to block and cool the direct sunlight. When the light weakens and the temperature drops, the bimetallic sheet gradually returns to its straight position, and the louvered curtain wall reopens to allow sunlight to penetrate into the room. Therefore, without any external energy source, the louvered curtain wall module can automatically adjust the opening and closing angle according to changes in solar radiation intensity, effectively blocking excessive heat from entering the room when the sunlight is strong, and maintaining lighting and increasing solar radiation heat gain when it is cold or there is insufficient sunlight. The louvered curtain wall module adopts an independent modular unit design. Each louvered curtain wall consists of multiple parallel bimetallic louvers and their frame, which are installed on the exterior wall via adjustable brackets. The brackets can adjust the installation angle and position of the louvered curtain wall module and are reliably fixed to withstand adverse outdoor factors such as wind loads. At night or on cloudy days, when there is no sunlight, the thermal bimetallic louvers will basically return to a straight state due to the lack of a heat source. At this time, the opening and closing of the louvered curtain wall needs to be adjusted by a motor drive. The system is equipped with an intelligent control module that can comprehensively judge the current environmental conditions (outdoor ambient temperature, indoor temperature, wind speed, etc.) to determine whether the louvered curtain wall should be in the open state to enhance ventilation or in the closed state to enhance insulation. The electric control structure of the louvered curtain wall uses a motor drive, which drives the transmission shaft to rotate through a gear set and pulls the lifting rope to change the tilt angle of the louvers, thereby achieving synchronous opening and closing control of the entire louvered curtain wall.In night mode or cloudy mode, the system automatically determines the opening or closing status of the louvered curtain wall based on the temperature difference between indoors and outdoors: when the indoor temperature is higher than the outdoor temperature, the louvered curtain wall is opened to a certain angle to promote the exhaust of hot indoor air and achieve natural ventilation and cooling at night; conversely, the louvered curtain wall is closed to reduce heat loss and maintain a stable indoor temperature. In addition, the louvered curtain wall is equipped with a wind pressure disturbance protection structure, such as a self-locking mechanism or mechanical stop, to ensure that the louvers maintain a predetermined tilt angle and do not shift when subjected to wind pressure. Each louvered curtain wall module can be independently disassembled and replaced, facilitating maintenance and configuration adjustments as needed. Besides utilizing the thermal actuation characteristics of the bimetallic strips, the louvered curtain wall of this invention can also be linked with an intelligent control system: ambient temperature and light sensors are installed on the exterior wall to monitor external conditions in real time. When natural conditions are insufficient to cause the louvers to bend as required (e.g., the louvered curtain wall needs to be closed at night to enhance insulation, or forced ventilation is required in special circumstances), the control module can start the motor to control the louvers to rotate to a suitable angle. Through the above design, the louvered curtain wall device maintains the advantages of passive self-adaptation while also possessing intelligent controllability, and can precisely adjust the ventilation and shading status of the exterior wall according to the overall system strategy.

[0059] The intelligent control module configured in this invention integrates an ambient temperature sensor, a light sensor, a building posture sensor, a central controller, and the aforementioned wax motor driver heating element, ventilation fan, electric valve, and other actuators. The control module is pre-set with trigger temperature thresholds for winter insulation mode and summer ventilation mode, and can automatically switch the building's operating mode according to changes in outdoor ambient temperature without manual intervention. When the outdoor temperature is lower than the preset threshold, the system switches to winter insulation mode: at this time, the paraffin driver 2 stops heating and remains in a shortened state, causing the building to descend to a position where the bottom is almost touching the ground, minimizing bottom gaps to prevent cold air intrusion; simultaneously, the air inlet 7 at the bottom of the building and the air outlet 8 at the top are closed, and the ventilation fan is turned off to keep the indoor air still and prevent heat loss; the louvered curtain wall module is controlled to be in an open, light-transmitting state (under low-temperature conditions, the bimetallic louvers have naturally returned to a straight, open position), ensuring indoor lighting and utilizing solar radiation to warm the interior; and the tilt angle of the roof photovoltaic panel 10 is adjusted to face the sun, maximizing the absorption of sunlight to provide additional heat and electricity support to the interior. Conversely, when the outdoor temperature exceeds a threshold, the system switches to summer ventilation mode: the paraffin actuator 2 is activated to heat and extend, lifting the house to the height of a ventilated air gap, increasing the airflow space at the bottom; simultaneously, the bottom air inlet 7 and the upper air outlet 8 are opened, and fans are activated to enhance air convection, introducing cooler air from the air gap into the room and expelling stagnant hot air from the top; the roof photovoltaic panels 10 are controlled to rotate to a near-vertical or appropriate shading angle, partially blocking direct sunlight at midday and using the electricity generated by the photovoltaic panels to drive fans and other equipment; under strong solar radiation, the exterior wall louvers automatically bend to a closed shading state, preventing excessive heat from entering the room. Through the above-mentioned coordinated control strategy, the building support height, ventilation opening and closing, wall shading, and solar panel angle are adjusted in a coordinated manner according to environmental changes, always maintaining a comfortable indoor temperature range.

[0060] Dynamic regulation process

[0061] 1. Temperature gradient calculation: The sensor collects temperature data every 5 minutes and calculates the ratio of the temperature difference in the thickness direction to the distance. For example, if the surface temperature of the base plate is 35℃ and the bottom temperature of the rock wool layer is 28℃ at a certain moment in summer, with a thickness of 0.1m, then the temperature gradient is 70℃ / m.

[0062] 2. Heat transfer assessment: Based on the thermal conductivity of the rock wool layer of 0.04 W / (m·K), the heat transfer intensity per unit area is calculated to be 28 W / m², which exceeds the summer threshold of 20 W / m². The system determines that overhead ventilation needs to be activated.

[0063] 3. Multi-system linkage: The driver completes the lifting (displacement of 6.9mm, response time reference) within 20 minutes, the louvered curtain wall angle is adjusted to 60° for shading, the photovoltaic panel tilt angle is adjusted to 30° to enhance the shading effect, the ventilation fan power is increased to 80%, and the indoor temperature drops by 7℃ within 1 hour.

[0064] Example 2: Running effect, see attached document. Figure 7

[0065] The building's operating mode is adaptively switched according to changes in outdoor ambient temperature: In low-temperature environments, the paraffin-based thermal expansion actuator (wax motor) is in a contracted state, causing the bottom of the house to be close to the rock wool layer on the ground, forming a closed support structure that effectively blocks the infiltration of cold air from the ground, reduces indoor heat loss, and significantly reduces heating energy consumption; In high-temperature environments, the wax motor expands when heated, lifting the house to form a bottom ventilated open space. In conjunction with the ventilation system, it introduces cold air from the bottom and exhausts hot air from the room, enhancing air convection and heat exchange, lowering the indoor temperature, reducing the load on the air conditioning system, and lowering cooling energy consumption.

[0066] By dynamically adjusting the wax motor lifting system, the system achieves the dual functions of efficient heat preservation in winter and natural ventilation in summer, enhancing the environmental adaptability of temporary buildings under multiple seasons and working conditions, significantly improving indoor thermal comfort, and meeting various application needs such as on-site operations and living.

[0067] Adopting a modular design concept, the wax motor support unit, the thermal bimetallic louver curtain wall component, and the ventilation auxiliary system are all standardized and detachable, which facilitates overall transportation, rapid assembly, and subsequent maintenance, and improves the portability and system expansion capabilities of the temporary building structure.

[0068] Equipped with an intelligent control system, it integrates multiple types of sensors such as temperature, light, and attitude, and links and controls the wax motor heater, the electric valve of the ventilation vent, the fan system, and the angle adjustment device of the solar photovoltaic panel. It realizes automatic coordinated response and operation mode switching between multi-functional modules, and has intelligent operation advantages such as simple operation, timely response, and energy consumption optimization.

[0069] By installing an adjustable rooftop solar photovoltaic system, structural support is provided for shading and temperature control, while making full use of solar energy resources to power the control system and actuators, reducing dependence on traditional electricity, reducing carbon emissions, and improving energy efficiency, which is in line with the development orientation of green buildings and the promotion of sustainable application scenarios.

[0070] To verify the necessity of the temperature control mechanism proposed in this invention, transient thermal simulations were performed on a typical container house structure using COMSOL Multiphysics to obtain the correlation between the indoor average temperature and ambient temperature, solar irradiance, and insulation layer thickness. After fitting the simulation results, the following empirical model was obtained:

[0071] y-ln(1810.10+0.023513T env -3.13378I+0.023994d)

[0072] Where: y represents the average temperature (°C) of the container volume, T env The ambient temperature (°C) is represented by I, the solar irradiance by d, and the insulation layer thickness by d.

[0073] The goodness of fit of the model is R. 2 The value is approximately 0.9418, indicating that it can accurately characterize the nonlinear relationship between room temperature and ambient temperature. Simulation results show that, without any temperature control measures, the room temperature is significantly higher than the ambient temperature due to solar radiation, and there is a lag peak, with a temperature difference of up to 10℃. The lifting support system and external wall shading system used in this invention can effectively reduce this lag and temperature rise trend, achieve indoor thermal balance regulation that is closer to the environment, reduce cooling load, and improve comfort.

[0074] Example 3: Application in high-temperature environments during summer, see attached document. Figure 4 and attached Figure 5

[0075] Scene setting

[0076] The construction site is located in the North China Plain, where extreme summer temperatures reach 38°C. Traditional prefabricated modular housing often experiences indoor temperatures exceeding 35°C, requiring air conditioning for cooling. This technology's modular housing was tested under these conditions.

[0077] Regulation process and data

[0078] 1. Real-time monitoring and prediction: The intelligent control system monitors the exterior wall surface temperature at 42℃ and the ambient air temperature at 36℃ using exterior surface temperature sensors, calculating a convective heat transfer temperature difference of 6℃. Based on historical data, it predicts that the indoor temperature will rise to 32℃ within the next 2 hours, triggering the cooling mechanism in advance.

[0079] 2. Shading and ventilation in tandem:

[0080] The louvered curtain wall automatically closes to the shading angle, reducing solar radiation heat input and lowering the surface temperature by 8°C.

[0081] The drive unit lifts the house, creating a 0.5m raised floor, increasing the thermal resistance of the rock wool layer by 0.3m. 2The heat transfer intensity decreased from 30 W / m² to 18 W / m².

[0082] When the ventilation system is activated, the fan speed reaches 3m / s at 80% power, the air inlet opens at 60°, the air outlet is fully open, and the indoor air exchange rate is 5 times per hour.

[0083] 3. Cooling effect:

[0084] One hour later, the indoor temperature stabilized at 26℃, which is 9℃ lower than that of traditional container houses.

[0085] The air conditioning load was reduced by 60%, and the average daily power consumption dropped from 12kWh to 4.8kWh. The photovoltaic power generation of 3.5kWh met 80% of the system's power demand.

[0086] Example 4: Application in cold winter environments, see attached document. Figure 6

[0087] Scene setting

[0088] In a certain high-altitude region, the extreme low temperature in winter reaches -25℃, while the indoor temperature of traditional prefabricated modular housing is only 5-8℃, requiring continuous heating. This technology's modular housing was tested under these conditions.

[0089] Regulation process and data

[0090] 1. Insulation Mode Activation: The intelligent control system detects that the heat transfer intensity of the bottom rock wool layer is below 10W / ㎡ (winter threshold), triggering the actuator to contract and bring the bottom of the house closer to the rock wool layer, eliminating the cold bridge effect of the elevated floor. At the same time, the louvered curtain wall opens to a 30° tilt angle to enhance solar radiation absorption.

[0091] 2. Photovoltaic and heating synergy:

[0092] The photovoltaic panels were adjusted to a 60° angle to maximize the reception of solar radiation, resulting in an average daily power generation of 4.2 kWh, a 30% increase compared to summer.

[0093] The intelligent control system predicts the nighttime cooling trend based on historical temperature data and starts the heating element to preheat the paraffin two hours in advance to ensure the driver's response speed.

[0094] 3. Insulation effect:

[0095] The indoor temperature is stable at 18-20℃, which is 12-15℃ higher than that of traditional container houses.

[0096] Heating energy consumption is reduced by 40%, and the average daily power consumption is reduced from 15kWh to 9kWh. Photovoltaic power generation covers 60% of the system's electricity demand.

[0097] Example 5: Extreme weather adaptability verification, see attached document. Figure 2 and attached Figure 3

[0098] Test environment

[0099] The drive's durability was tested in an extreme temperature range of -30℃ to 60℃ to simulate complex environments such as plateaus and deserts.

[0100] Performance

[0101] 1. Actuator Stability: The paraffin-based thermal expansion actuator, employing a double-sealed design (Glydring + Step seal), outputs a displacement of 6.5mm at -30℃ with a heating power of 40W, a response time of 22 minutes, and a driving force of 310N, meeting the roof lifting requirements. After 100 cycles of testing, the displacement fluctuation is controlled within ±0.3mm, with no paraffin leakage.

[0102] 2. Wind pressure resistance of louvered curtain wall: In the test of strong wind of level 6 (wind speed 10.8-13.8m / s), the thermal bimetallic louvered curtain wall module maintained a stable posture through the self-locking mechanism, and no angle displacement or structural deformation occurred.

[0103] 3. Overall energy efficiency: In a high-temperature environment of 60℃, the system maintains an indoor temperature 12℃ lower than the outside temperature through overhead ventilation, shading and forced heat dissipation; in a low-temperature environment of -30℃, the rock wool layer and the actuator work together to maintain the indoor temperature above 16℃, verifying the adaptability of the entire temperature range from -30℃ to 60℃.

[0104] Data support

[0105] Driver life: After 100 cycles of testing, the displacement stability error is <5%, and the sealing performance is not degraded.

[0106] Extreme temperature adaptability: In an environment of -30℃, the driver heating element begins to rise within 15 minutes after startup, which is 20% longer than the response time in a normal temperature environment, but still meets engineering requirements.
