However, this method simply blocks heat between the interior and exterior and cannot fully utilize the heat in the outdoor air or the heat from solar radiation. Therefore, the energy-saving effect is generally average, and the efficiency of reducing building energy consumption is also average. Summary of the Invention

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1-7 As shown, in one embodiment, an energy-saving thermal insulation and regulation structure for prefabricated integrated buildings is provided, including an AAC board 1, with multiple thermal insulation and regulation components rotatably connected inside the AAC board 1 for controlling the temperature on both sides of the AAC board 1.

[0047] A drive assembly, mounted on AAC plate 1, is used to drive multiple temperature-regulating components to rotate.

[0048] The sensor acquisition and monitoring component is used to collect and monitor data such as temperature and light intensity on both sides of the AAC board 1.

[0049] A data processing and control system is used to analyze data collected by sensors and control drive components.

[0050] Through the above technical solution, in this embodiment, the sensor acquisition and monitoring component collects data such as the temperature on the inside and outside of the AAC board 1, as well as the light intensity, and transmits them to the data processing and control system. The data processing and control system analyzes the data collected by the sensor and controls the drive component, causing the drive component to drive multiple temperature-regulating components inside the AAC board 1 to rotate or reset. The AAC board 1 is a high-performance autoclaved lightweight aerated concrete board, which is a porous concrete board made of fly ash or silica sand, cement, lime, etc. as the main raw materials, and is cured by rust prevention and high temperature, high pressure, and steam. It has good thermal insulation properties and can reduce building energy consumption.

[0051] As one embodiment of the present invention, please refer to Figures 1-3 As shown, the temperature insulation and regulation component includes a metal cylinder 6, which has a cylindrical cross-section. The outer surface of the metal cylinder 6 is divided into four regions. A reflective coating is provided on two opposite regions, and a heat-absorbing coating is provided on the other two opposite regions.

[0052] As another embodiment of the present invention, please refer to Figures 4-6 As shown, the thermal insulation regulating component includes a metal cylinder 6 with a rectangular ring cross-section, wherein the two opposite sides of the rectangular ring are arc-shaped. A heat-absorbing coating is provided on two arc-shaped surfaces on the outer surface of the metal cylinder 6. A polarizing mirror 3 and a thermal insulation material 7 are fixedly connected to two planes on the outer surface of the metal cylinder 6, respectively. A reflective coating is provided between the polarizing mirror 3 and the metal cylinder 6. The polarizing mirror 3 can deflect part of the light rays that hit the polarizing mirror 3, so that they do not hit the reflective coating, thereby reducing the solar radiation received by the reflective coating and further reducing the heat absorbed by the metal cylinder 6. The thermal insulation material 7 can block the heat on the metal cylinder 6, reducing the heat transferred from the metal cylinder 6 to the building through the thermal insulation material 7, and further insulating the interior of the building.

[0053] Preferably, the material used for the reflective coating can be silver or aluminum, and the material used for the heat-absorbing coating can be pigment carbon black or iron oxide black. The reflective coating can reflect most of the solar radiation, thereby reducing the effect of the metal cylinder 6 in absorbing solar energy. The black coating can absorb most of the solar radiation, thereby improving the effect of the metal cylinder 6 in absorbing solar energy.

[0054] Furthermore, in order to improve the temperature regulation effect of the insulation and regulation component, the metal cylinder 6 is divided into multiple cavities 62 from top to bottom by partitions 61. The cavities 62 are filled with phase change material, which is a solid-liquid phase change material with a melting point that is the most suitable temperature for the human body.

[0055] As one embodiment of the present invention, please refer to Figures 1-6 As shown, the drive assembly includes a servo motor 42 and a rotating shaft 5. The rotating shaft 5 is fixedly connected to the central shaft of the metal cylinder 6. A second bevel gear 51 is fixedly connected to one end of the rotating shaft 5. The servo motor 42 is fixedly connected to the AAC plate 1. A drive rod 4 is fixedly connected to the output end of the servo motor 42. A first bevel gear 41 is fixedly connected to the drive rod 4. The first bevel gear 41 meshes with the second bevel gear 51. The output end of the servo motor 42 can drive the drive rod 4 to rotate. Since the first bevel gear 41, which is connected to each of the second bevel gears 51, is fixedly connected to the drive rod 4, the drive rod 4 can synchronously drive each rotating shaft 5 and the metal cylinder 6 to rotate during the rotation process.

[0056] The sensor acquisition and monitoring components include:

[0057] The first temperature sensor, located inside the AAC board 1, is used to collect and monitor the temperature inside the building.

[0058] A second temperature sensor, located on the outer side of the AAC board 1, is used to collect and monitor the external temperature of the building.

[0059] A light sensor is installed on the outer side of the AAC board 1 to collect and monitor the intensity of light outside the building.

[0060] The data processing and control system includes:

[0061] The analysis module is used to analyze and calculate the information collected by each sensor. The specific process is as follows:

[0062] The metal cylinder 6 is initially positioned so that the heat-absorbing coating is housed within the AAC plate 1;

[0063] like >1 and When >1, or <1 and When <1, the metal cylinder 6 rotates until the heat-absorbing coating is exposed outside the AAC plate 1;

[0064] like ≤1 and When ≥1, or ≥1 and When ≤1, the metal cylinder 6 rotates back to its initial position;

[0065] in, Indoor temperature, Outdoor temperature Lx represents the optimal temperature for the human body, and Lx represents the intensity of sunlight outdoors. The photothermal conversion coefficient;

[0066] It should be noted that, It can be obtained based on the absorption rate of solar radiation by the heat-absorbing coating and the material of the metal cylinder 6.

[0067] The control module is used to control the start and stop of the drive components in order to control the rotation of the metal cylinder 6.

[0068] Furthermore, to improve the comfort of residents in the building, a wooden board 2 is installed on the inner surface of the AAC board 1, and the surface of the metal cylinder 6 is in contact with the inner wall of the wooden board 2. In this way, when any heat-absorbing coating of the metal cylinder 6 rotates to the outside of the AAC board 1, the heat-absorbing coating can quickly absorb the heat from the outside air and the heat generated by solar radiation. Then, it is quickly transferred to another heat-absorbing coating through the metal material of the metal cylinder 6. At this time, the heat-absorbing coating is in contact with the inner wall of the wooden board 2, and can transfer the absorbed heat to the wooden board 2. The heat is then slowly diffused into the air inside the building through the wooden board 2. The heat is transferred and diffused through the wooden board 2, which can prevent residents from touching the black coating of the metal cylinder 6 and being burned while living in the building.

[0069] The specific usage process of this adjustment structure,

[0070] For example, on a summer night, when the indoor air temperature is higher than the optimal temperature for the human body, and the indoor air temperature is greater than the sum of the outdoor air temperature and the temperature rise of the heat-absorbing coating, the data processing and control system can control the metal cylinder 6 to rotate until the heat-absorbing coating is exposed to the outside of the AAC board 1. This allows the two heat-absorbing coatings on the metal cylinder 6 to come into contact with the outside and the wooden board 2, respectively. At this time, the heat-absorbing coating in contact with the wooden board 2 can quickly absorb the heat in the indoor air and transfer it through the metal cylinder 6 to the heat-absorbing coating in contact with the outside air. The heat-absorbing coating can quickly transfer the heat to the outside air. In this process, the phase change material located in the multiple cavities 62 inside the metal cylinder 6 will absorb heat and melt, thereby achieving the purpose of rapidly cooling the indoor air temperature.

[0071] When the indoor air temperature drops to the sum of the outdoor air temperature and the temperature rise due to heat absorption by the heat-absorbing coating, or when the indoor air temperature drops to the optimal temperature for the human body, the data processing and control system can control the metal cylinder 6 to rotate and reset, causing the two opposing heat-absorbing coatings to rotate and be housed within the AAC panel 1. The reflective coating and insulation material then block heat exchange between the inside and outside of the building, preventing continuous convective heat exchange. If the indoor air temperature has already reached the optimal temperature for the human body, simply keeping the metal cylinder 6 in its reset state is sufficient. If the indoor temperature has not yet dropped to the optimal temperature for the human body, but has already reached the sum of the outdoor air temperature and the temperature rise due to heat absorption by the heat-absorbing coating, the data processing and control system can further activate the building's cooling equipment to further cool the indoor air. At this time, the metal cylinder 6 is in its reset state, effectively blocking the temperature exchange between the outside and inside of the building, thus preventing heat exchange between the outside temperature and the air cooled by the cooling equipment inside the building. This process achieves the first stage of cooling through heat exchange between the inside and outside, and the second stage of cooling by using the cooling equipment while blocking heat exchange between the inside and outside. Compared with existing technologies, this further reduces building energy consumption.

[0072] For example, on a sunny winter day, when the indoor air temperature is lower than the optimal human body temperature, and the indoor air temperature is lower than the sum of the outdoor air temperature and the temperature rise of the heat-absorbing coating, the data processing and control system can control the metal cylinder 6 to rotate until the heat-absorbing coating is exposed to the outside of the AAC board 1. This allows the two heat-absorbing coatings on the metal cylinder 6 to come into contact with the outside and the wooden board 2 respectively. At this time, the heat-absorbing coating in contact with the outside air can quickly absorb and raise the temperature of the heat in the outside air and the heat generated by solar radiation. This heat is then transferred through the metal cylinder 6 to the heat-absorbing coating that is attached to the wooden board 2. The heat-absorbing coating can quickly transfer the heat to the wooden board 2, heating the wooden board 2 inside the building. This raises the temperature of the wooden board 2, which in turn raises the temperature of the air inside the building. The wooden board 2 can increase the contact area between the heat-absorbing coating and the indoor air, and the temperature rise will not change suddenly, so as not to cause burns to the residents of the building. At the same time, it can quickly and effectively raise the indoor air temperature. In this process, when the temperature of the metal cylinder 6 exceeds the optimal human body temperature, the phase change material located in the multiple cavities 62 inside the metal cylinder 6 will also slowly absorb heat and melt, thereby storing the heat from the outside.

[0073] When the indoor air temperature rises to the sum of the outdoor air temperature and the temperature rise due to heat absorption by the heat-absorbing coating, or when the indoor air temperature rises to the optimal temperature for the human body, the data processing and control system can control the metal cylinder 6 to rotate and reset, causing the two opposing heat-absorbing coatings to rotate and be housed within the AAC board 1. Through the reflective coating and insulation material, heat between the inside and outside of the building is blocked, preventing continuous convective exchange of heat. If the indoor air temperature has already reached the optimal temperature for the human body, the metal cylinder 6 can remain in its reset state. If the indoor temperature has not yet reached the optimal temperature for the human body, but has already reached the sum of the outdoor air temperature and the temperature rise due to heat absorption by the heat-absorbing coating, the data processing and control system can further activate the building's heating equipment to further heat the indoor air. At this time, the metal cylinder 6 is in its reset state, blocking the temperature difference between the inside and outside of the building, thus preventing heat exchange between the outside temperature and the air heated by the heating equipment inside the building. This process involves the first stage of heating through heat exchange between the inside and outside, and the second stage of heating by using the heating equipment while blocking heat exchange. Compared with existing technologies, this further reduces building energy consumption.

[0074] Furthermore, to facilitate reducing the frequency of data processing and control of the data acquisition system, and thus reducing the control frequency of the drive components to decrease building energy consumption, the metal cylinder 6 is rotated to an angle N = [missing value]. * ;

[0075] Wherein, f(t) is a curve of outdoor air temperature and the temperature rise of the heat-absorbing coating obtained by predicting meteorological information and the location of the building. For the future The time period The rotation angle coefficient of the metal cylinder 6, the The data processing and control system can be manually configured. according to The amount of indoor temperature change required over a period of time is obtained through experience.

[0076] The adjustment method for the adjustment structure is as follows:

[0077] Step 1: The sensor acquisition and monitoring components collect data on the temperature inside the building and the temperature and light intensity outside the building and transmit it to the data processing and control system.

[0078] Step 2: The data processing and control system analyzes the information collected by the sensors and determines whether the drive components need to be activated.

[0079] Step 3: If the drive component is working, that is, the servo motor 42 rotates in a fixed process, it drives the rotating shaft 5 and the metal cylinder 6 to rotate through the drive rod 4, thereby adjusting the orientation of each coating on the outside of the metal cylinder 6.

[0080] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
