Description

Technical Field

[0001] This invention belongs to the field of building energy conservation and prefabricated temporary building equipment technology, and specifically relates to an intelligent roll-up insulation device and method for temporary buildings. Background Technology

[0002] Existing temporary buildings generally use fixed external insulation panels or conventional sandwich panels, whose insulation capacity is limited by the material thickness and cannot simultaneously achieve rapid installation and active adjustment capabilities in response to temperature changes. When there are large temperature differences in the external environment or drastic temperature fluctuations between day and night, fixed insulation structures cannot achieve real-time control, resulting in a significant increase in heat loss.

[0003] In addition, traditional roller blinds are mostly used for sun shading and are difficult to achieve building-grade insulation; at the same time, their wind resistance is insufficient and they cannot remain stable in complex outdoor environments.

[0004] Therefore, there is an urgent need for an intelligent external insulation system that can automatically unfold or retract according to temperature, has strong adhesion, high wind resistance, and is suitable for temporary buildings, in order to meet the future needs of temporary buildings for energy saving, rapid construction, and reliable use under extreme working conditions. Summary of the Invention

[0005] The present invention aims to provide an intelligent roll-up insulation device and method for temporary buildings, which solves the problems of existing temporary building external insulation devices being unable to be actively controlled, having low installation efficiency, and being inconvenient to install.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A smart roll-up insulation device for temporary buildings includes: a temperature monitoring device, a phase change insulation blanket, a roller, a fixed bracket, and a roller shutter driver. The roller shutter driver includes a motor, a reduction gear mechanism, and a control module. The roller shutter driver and the fixed bracket are respectively installed on the outer surface of the top of the exterior wall of the temporary building. The roller is horizontally arranged, and its two ends are respectively supported on the outer surface of the top of the exterior wall of the temporary building via the fixed bracket and the roller shutter driver. The roller is mounted on the fixed bracket via bearings. The temperature monitoring device is fixedly installed on the fixed bracket. The phase change insulation blanket is rolled onto the roller. The motor is connected to the reduction gear mechanism, and the reduction gear mechanism is connected to the roller. The motor can drive the roller forward and backward through the reduction gear mechanism. The motor is connected to and controlled by the control module, which is communicatively connected to the temperature monitoring device. The control module has preset temperature thresholds, including a minimum and a maximum value. The temperature monitoring device can monitor the temperature outside the temporary building in real time and send the measured temperature data to the control module. The control module can determine whether the measured temperature data exceeds the temperature threshold. When the measured temperature data is below the minimum value, the control module drives the motor to rotate forward, causing the phase change insulation blanket to be lowered and laid on the outer surface of the temporary building's exterior wall. When the measured temperature data is above the maximum value, the control module drives the motor to rotate in reverse, causing the phase change insulation blanket to roll up.

[0008] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, multiple circular thin magnets are equidistantly embedded in the periphery and center of the phase change insulation blanket. The circular thin magnets are made of high remanence Nd-Fe-B thin sheets to ensure that they can be quickly attracted to the color steel sandwich panel when laid down, so as to achieve full-fit coverage.

[0009] Preferably, in the intelligent roll-up insulation device for temporary buildings described above, the temperature monitoring device employs a digital temperature sensor, supporting real-time monitoring in environments ranging from -30℃ to 80℃. The temperature monitoring device transmits the surface temperature of the temporary building to the control module of the roll-up driver every 1-3 seconds via a low-power Bluetooth communication unit. The digital temperature sensor possesses high sensitivity, enabling high-frequency, accurate, and low-power acquisition of the external surface temperature range, providing real-time decision-making support for intelligent roll-up.

[0010] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the outer shell of the temperature monitoring device adopts a dustproof and waterproof structure, which is suitable for rain, snow, wind and sand and high humidity environment at the construction site.

[0011] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the phase change insulation blanket is a flexible multi-layer composite structure. The phase change insulation blanket includes a phase change energy storage layer, a thermally stable support layer, and an outer protective layer. The upper and lower surfaces of the phase change energy storage layer are respectively covered with an outer protective layer, and a thermally stable support layer is provided between the phase change energy storage layer and the outer protective layer.

[0012] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the phase change energy storage layer adopts microencapsulated phase change material or high heat capacity composite material, which has dual energy storage capabilities of sensible heat and latent heat. It can actively adjust the temperature of the enclosure surface through the phase change process under day-night temperature difference or cold wave conditions, significantly improving the thermal inertia and stability of the temporary building.

[0013] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the outer protective layer is a flame-retardant, waterproof, tear-resistant and UV-resistant composite coating, suitable for long-term exposure to outdoor wind and rain environments.

[0014] Preferably, in the intelligent roll-up insulation device for temporary buildings described above, the thermally stable support layer adopts a flexible fiber skeleton to improve the overall bending resistance, ensuring that the insulation blanket maintains structural integrity and uniform unfolding performance after multiple rolls. The insulation blanket is rollable and can be rapidly unrolled and retracted around a roller.

[0015] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the roll is made of high-strength aluminum alloy, the motor is a high-torque, low-noise brushless motor that can operate stably at a low temperature of -20℃, and the control module supports voltage fluctuation compensation, stall protection, and manual / automatic dual-mode switching to ensure safe and reliable operation at the construction site.

[0016] The present invention also discloses a method of using the intelligent roll-up insulation device for temporary buildings as described above, comprising:

[0017] A smart roll-up insulation device for temporary buildings is installed on the exterior walls of the temporary buildings. The smart roll-up insulation device for temporary buildings includes: a temperature monitoring device, a phase change insulation blanket, a roller, a fixed bracket, and a roller shutter driver. The roller shutter driver includes a motor, a reduction mechanism, and a control module. The roller shutter driver and the fixed bracket are respectively installed on the top outer surface of the exterior wall of the temporary building. The roller is horizontally set, and its two ends are respectively supported on the top outer surface of the exterior wall of the temporary building through the fixed bracket and the roller shutter driver. The roller is mounted on the fixed bracket through bearings. The temperature monitoring device is fixedly installed on the fixed bracket. The phase change insulation blanket is rolled onto the roller. The motor drives the roller to rotate forward or backward through the reduction mechanism. The motor is connected to and controlled by the control module. The control module is communicatively connected to the temperature monitoring device. The control module presets a temperature threshold, which includes a minimum value and a maximum value.

[0018] The temperature monitoring device can monitor the temperature outside the temporary building in real time and send the temperature data measured by the temperature monitoring device to the control module.

[0019] The control module determines whether the temperature data measured by the temperature monitoring device exceeds the temperature threshold. When the temperature data measured by the temperature monitoring device is lower than the minimum value, the control module drives the motor to rotate forward, causing the phase change insulation blanket to be lowered and laid on the outer surface of the temporary building's exterior wall. When the temperature data measured by the temperature monitoring device is higher than the maximum value, the control module drives the motor to rotate in reverse, causing the phase change insulation blanket to be rolled up.

[0020] As can be seen from the above-disclosed technical solutions, compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The present invention provides an intelligent roll-up insulation device and method for temporary buildings, employing a temperature monitoring device, a phase change insulation blanket, a roller, a fixing bracket, and a roller shutter driver. The roller shutter driver includes a motor, a reduction mechanism, and a control module. The temperature monitoring device can monitor the temperature outside the temporary building in real time and send the temperature data measured by the temperature monitoring device to the control module. The control module determines whether the temperature data measured by the temperature monitoring device exceeds a temperature threshold. When the temperature data measured by the temperature monitoring device is lower than the minimum value, the control module drives the motor to rotate forward, causing the phase change insulation blanket to be lowered and laid on the outer surface of the exterior wall of the temporary building.

This enables automatic roll-up and unrolling control of the phase change insulation blanket according to the ambient temperature, allowing for rapid deployment and storage of the phase change insulation blanket, and significantly improving the energy-saving performance and construction efficiency of temporary buildings.

It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention. For ease of description, the terms "upper" and "lower" used below are consistent with the upper and lower directions in the accompanying drawings, but this should not be construed as a limitation of the technical solution of the present invention.

[0028] Please see Figures 1 to 4This embodiment discloses an intelligent roll-up insulation device for temporary buildings, comprising: a temperature monitoring device 1, a phase change insulation blanket 2, a roller 3, a fixing bracket 4, and a roller shutter driver 5. The roller shutter driver 5 includes a motor (not shown), a reduction mechanism (not shown), and a control module (not shown). The roller shutter driver 5 and the fixing bracket 4 are respectively installed on the outer surface of the top of the exterior wall 6 of the temporary building. The roller 3 is horizontally arranged, and its two ends are respectively supported on the outer surface of the top of the exterior wall 6 of the temporary building through the fixing bracket 4 and the roller shutter driver 5. The roller 3 is mounted on the fixing bracket 4 through bearings. The temperature monitoring device 1 is fixedly installed on the fixing bracket 4. The phase change insulation blanket 2 is rolled onto the roller 3. The motor is connected to the reduction mechanism, and the reduction mechanism is connected to the roller 3. The motor can drive the roller 3 to rotate forward or backward through a reduction mechanism. The motor is connected to and controlled by a control module. The control module is communicatively connected to the temperature monitoring device 1. The control module has preset temperature thresholds, including minimum and maximum values. The temperature monitoring device 1 can monitor the temperature outside the temporary building in real time and send the temperature data measured by the temperature monitoring device 1 to the control module. The control module can determine whether the temperature data measured by the temperature monitoring device 1 exceeds the temperature threshold. When the temperature data measured by the temperature monitoring device 1 is lower than the minimum value, the control module drives the motor to rotate forward, causing the phase change insulation blanket 2 to be lowered and laid on the outer surface of the temporary building's outer wall. When the temperature data measured by the temperature monitoring device 1 is higher than the maximum value, the control module drives the motor to rotate backward, causing the phase change insulation blanket 2 to roll up.

[0029] The present invention provides an intelligent roll-up insulation device for temporary buildings, comprising: a temperature monitoring device 1, a phase change insulation blanket 2, a roller 3, a fixing bracket 4, and a roller shutter driver 5. The roller shutter driver 5 includes a motor, a reduction mechanism, the roller 3, and a control module. The temperature monitoring device 1 can monitor the temperature outside the temporary building in real time and send the temperature data measured by the temperature monitoring device 1 to the control module.

When the temperature data measured by the temperature monitoring device 1 is higher than the maximum value, the control module drives the motor to rotate in reverse, causing the phase change insulation blanket 2 to roll up. This enables the phase change insulation blanket 2 to automatically roll up and down according to the ambient temperature, allowing for rapid deployment and storage of the phase change insulation blanket 2, and significantly improving the energy-saving performance and construction efficiency of temporary buildings.

[0030] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, multiple circular thin magnets 21 are equidistantly embedded in the periphery and center of the phase change insulation blanket 2. These circular thin magnets 21 are made of high-remanence Nd-Fe-B sheets. Since the color steel sandwich panels in the outer wall 6 of the temporary building have magnetic attraction, by equidistantly embedding multiple circular thin magnets 21 in the periphery and center of the phase change insulation blanket 2, the phase change insulation blanket 2 has an active adhesion capability. This allows the phase change insulation blanket 2 to quickly and automatically adhere to the color steel sandwich panels in the outer wall 6 of the temporary building when it is lowered. This ensures that the phase change insulation blanket 2 fully adheres to the surface of the outer wall 6 of the temporary building, forming a stable insulation layer on the outer surface of the wall and effectively resisting wind loads. This significantly improves the laying efficiency, insulation effect, and wind resistance of the phase change insulation blanket 2, ensuring that the phase change insulation blanket 2 remains stable and does not move in strong winds.

[0031] Preferably, in the intelligent roll-up insulation device for temporary buildings described above, the temperature monitoring device 1 employs a digital temperature sensor, supporting real-time monitoring in environments ranging from -30℃ to 80℃. The temperature monitoring device 1 transmits the surface temperature of the temporary building to the control module of the roll-up driver 5 every 1-3 seconds via a low-power Bluetooth communication unit. The digital temperature sensor possesses high sensitivity, enabling high-frequency, accurate, and low-power acquisition of the external surface temperature range, providing real-time decision-making support for intelligent roll-up.

[0032] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the outer shell of the temperature monitoring device 1 adopts a dustproof and waterproof structure (IP65 or above) to adapt to rain, snow, sandstorms and high humidity environment at the construction site.

[0033] The roller shutter driver 5 also includes a mounting frame, on which the motor, reduction mechanism and control module are distributed and mounted. A protective shell is also provided on the outside of the mounting frame, and a through hole is provided on the protective shell for the roller 3 to pass through.

[0034] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the phase change insulation blanket 2 is a flexible multi-layer composite structure. The phase change insulation blanket 2 includes a phase change energy storage layer, a thermally stable support layer, and an outer protective layer. The upper and lower surfaces of the phase change energy storage layer are respectively covered with an outer protective layer, and a thermally stable support layer is provided between the phase change energy storage layer and the outer protective layer.

[0035] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the phase change energy storage layer adopts microencapsulated phase change material or high heat capacity composite material, which has dual energy storage capabilities of sensible heat and latent heat. It can actively adjust the temperature of the enclosure surface through the phase change process under day-night temperature difference or cold wave conditions, significantly improving the thermal inertia and stability of the temporary building.

[0036] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the outer protective layer is a flame-retardant, waterproof, tear-resistant and UV-resistant composite coating, suitable for long-term exposure to outdoor wind and rain environments.

[0037] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the thermally stable support layer adopts a flexible fiber skeleton to improve the overall bending resistance, so that the insulation blanket can maintain structural integrity and uniform unfolding performance after multiple rolls, and can be rolled up and down at high speed around the roll 3.

[0038] Preferably, in the intelligent roll-up insulation device for temporary buildings as described above, the roller 3 is made of high-strength aluminum alloy, the motor is a high-torque, low-noise brushless motor that can operate stably at -20℃, and the control module supports voltage fluctuation compensation, stall protection, and manual / automatic dual-mode switching to ensure safe and reliable operation at the construction site.
