[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0042] Referring to Figures 1-4 A 3D printing aerogel insulation board assembly structure and an assembly method thereof, comprising a protection plate group 1, the inside of the protection plate group 1 is provided with an aerogel insulation layer 2, the inside of the protection plate group 1 is provided with a cavity, the top of the protection plate group 1 is provided with an upper support plate 9, the top of the upper support plate 9 is provided with a ventilation assembly 10, the ventilation assembly 10 comprises a fan 1004, the negative pressure of the external fan 1004 during work is used to discharge the gas in the cavity outward, the bottom of the protection plate group 1 is provided with a bottom plate 101, the aerogel insulation layer 2 divides the cavity into an inner cavity 4 and an outer ventilation cavity 3, the outer ventilation cavity 3 is used to cooperate with the ventilation assembly 10 to exchange the inner and outer gas, and the heat of solar energy in the outer ventilation cavity 3 is discharged.

[0043] As an option, the inner cavity 4 is used as a hidden channel of a line or a pipeline, and can be used for maintenance and repair of the aerogel insulation layer 2 module. In actual use, according to the use requirement, there is only one outer ventilation cavity 3 between the aerogel insulation layer 2 and the protection plate group 1, which reduces the occupied space of the protection plate group 1.

[0044] The ventilation assembly 10 comprises a branch pipe 1001 and a total air outlet pipe 1002, the branch pipe 1001 is communicated with the outer ventilation cavity 3, the fan 1004 is arranged on the total air outlet pipe 1002, the protective plate group 1 is provided with a ventilation opening in the corresponding position of the outer ventilation cavity 3, and the external gas enters the outer ventilation cavity 3 through the ventilation opening.

[0045] In use, the external gas enters the outer ventilation cavity 3 through the ventilation opening, and then is discharged outwardly through the branch pipe 1001 and the total air outlet pipe 1002 of the ventilation assembly 10, so as to exchange the internal and external gases in the outer ventilation cavity 3. In the outer ventilation cavity 3, a temperature sensor can be preset, a temperature threshold T1 is preset in the temperature sensor, when the temperature in the outer ventilation cavity 3 reaches the preset temperature threshold T1, the fan 1004 switch on the total air outlet pipe 1002 is started, the exchange speed of the internal and external gases in the outer ventilation cavity 3 is accelerated, and the cooling speed in the outer ventilation cavity 3 is improved. Figure 4The inner part of the outer ventilation cavity 3 is provided with a partition plate 5, the partition plate 5 divides the outer ventilation cavity 3 into a plurality of unit cavities, the bottom plate 101, the protection plate group 1, the upper supporting plate 9 and the aerogel thermal insulation layer 2 form a unit cavity, correspondingly, the branch pipe 1001 is provided with a plurality of branch pipes 1001, the plurality of branch pipes 1001 correspond to the plurality of unit cavities one by one, the ventilation opening is provided with a plurality of groups of ventilation openings, the plurality of groups of ventilation openings correspond to the plurality of unit cavities respectively, the bottom of the partition plate 5 is fixedly connected with the bottom plate 101, one side of the partition plate 5 close to the aerogel thermal insulation layer 2 is provided with a partition plate 505, one side of the partition plate 505 is provided with a sealing gasket, the two sides of the sealing gasket are respectively attached with the aerogel thermal insulation layer 2 and the partition plate 505, the top of the bottom plate 101 is provided with a mounting plate 102, the mounting plate 102 is used for mounting and supporting the aerogel thermal insulation layer 2, in use, the plurality of unit cavities are used as independent spaces, each unit cavity corresponds to a group of ventilation openings, the plurality of groups of ventilation openings are respectively used as the special air inlets of the plurality of unit cavities, corresponding to the plurality of unit cavities, the plurality of branch pipes 1001 in the ventilation assembly 10 are respectively used as the air outlet ends of the plurality of unit cavities, and the electromagnetic valve 1003 is arranged on the branch pipe 1001, which is used to control the communication state between the unit cavity and the total air outlet pipe 1002.Furthermore, an air inlet assembly 6 is provided on the protective plate assembly 1 at a position corresponding to the vent. The air inlet assembly 6 includes a ventilation section 7, which includes a ventilation cylinder 701 fixedly connected to the vent. A sealing column 702 is provided inside the ventilation cylinder 701. A corrugated pipe 703 is provided at the end of the ventilation cylinder 701 away from the protective plate assembly 1, and a docking plate 704 is provided at the end of the corrugated pipe 703 away from the ventilation cylinder 701. An air inlet hole 7041 corresponding to and cooperating with the sealing column 702 is provided on the docking plate 704. It can be understood that the end of the sealing column 702 is frustoconical, and the diameter of the end of the sealing column 702 near the docking plate 704 is smaller to facilitate the docking of the air inlet hole 7041 with the sealing column 702. In use, an air humidity sensor can be provided inside the ventilation cylinder 701. An air humidity threshold H1 is preset in the air humidity sensor. When the external ventilation cavity 3 exchanges internal and external gases, the gas entering the external ventilation cavity 3 is monitored. If the gas humidity reaches the threshold H1, in order to prevent the external ventilation cavity 3 from being affected by subsequent air exchange, the sensor will detect the air humidity. As the humidity inside increases, the power of the fan 1004 on the main exhaust duct 1002 is increased, raising its speed. During this process, the gas entering the external ventilation chamber 3 through the air inlet 7041 cannot meet the exhaust volume demand of the fan 1004, creating a negative pressure within the external ventilation chamber 3. This negative pressure rapidly increases, attracting the docking plate 704 located outside the protective plate assembly 1 towards the ventilation cylinder 701, while simultaneously compressing the space between the ventilation cylinder 701 and the docking plate 704. The bellows 703 has a steel wire spring inside, which provides support for the bellows 703, ensuring that the air inlet 7041 corresponds to the sealing column 702. When the bellows 703 contracts, the air inlet 7041 of the connecting plate 704 is stably connected to the sealing column 702. A wear-resistant layer on the axial surface of the sealing column 702 improves the stability of the sealing connection between the air inlet 7041 and the sealing column 702, thus completing the sealing of the ventilation duct 701. This effectively reduces the risk of humid air or rainwater entering the external ventilation cavity 3 under the continuous negative pressure suction of the fan 1004 during humid or rainy weather. This would cause rainwater or moisture to soak the aerogel insulation layer 2, leading to an increase in the thermal conductivity of the subsequent aerogel insulation layer 2. Furthermore, the moisture and rainwater in the external ventilation cavity 3 cannot be effectively discharged in time, potentially causing mold growth inside the unit cavity.

[0046] In practical applications, when the external ventilation cavity 3 is a whole, the temperature distribution inside the external ventilation cavity 3 is uneven due to the different positions, orientations, and solar radiation intensities of the protective plate group 1. Since the gas usually only enters from the ventilation duct 701 with the least resistance, some areas may experience poor heat dissipation or humidity accumulation during use. Therefore, as a preferred method, multiple temperature sensors are installed in multiple unit cavities. The temperature sensor in each unit cavity detects the temperature value inside the unit cavity. When the temperature threshold in a certain unit cavity reaches the preset threshold T1, if the temperature threshold in other unit cavities is maintained at a safe temperature value below the threshold T1, the solenoid valve 1003 on the top branch pipe 1001 of other unit cavities remains closed. Then, the fan 1004 continuously draws in the high-temperature gas in the unit cavity where the temperature threshold has reached T1. External gas continuously enters the unit cavity through the air inlet 7041 and is then drawn out by the negative pressure of the fan 1004. The airflow is maintained through air exchange to dissipate the high-temperature unit cavity.

[0047] However, it is understandable that during the process of using the fan 1004 to draw external gas into the unit cavity and then discharging it outward through the main exhaust duct 1002, the path of the gas entering the unit cavity and flowing upward is fixed. In some localized areas outside the airflow path within the unit cavity, blind spots for airflow heat exchange can form, resulting in incomplete heat dissipation within the unit cavity. Therefore, as a further preferred embodiment, refer to... Figures 5-9 A turbulence-disrupting section 8 is provided at the end of the ventilation duct 701 away from the bellows 703 to agitate the gas flowing into the unit cavity. Specifically, the turbulence-disrupting section 8 includes an impeller 801 rotatably connected inside the ventilation duct 701. A connecting rod 802 is provided in the middle of the impeller 801, and a rotating plate 803 is provided at the end of the connecting rod 802 away from the impeller 801. Agitator blades 804 are provided on the outer side of the rotating plate 803. During use, under the negative pressure suction of the fan 1004, external gas is drawn through the air inlet 70... 41. When the airflow enters the unit cavity and passes through the impeller 801, the airflow passes through the blades of the impeller 801 and causes the impeller 801 to start rotating. At the same time, the impeller 801 drives the rotating plate 803 and the disturbance blade 804 to rotate concentrically. The end of the disturbance blade 804 away from the rotating plate 803 is close to the side of the partition plate 5. When the disturbance blade 804 rotates, it covers the space inside the unit cavity to a great extent. By utilizing the rotational disturbance effect of the disturbance blade 804 in the unit cavity, high temperature and high humidity gas is prevented from accumulating locally in the unit cavity.

[0048] refer to Figure 5 , Figure 6 , Figure 10 and Figure 11The protective panel assembly 1 is equipped with an internal circulation insulation system 11. The internal circulation insulation system 11 includes an air intake pipe 1101. One end of the air intake pipe 1101 is connected to the bottom of the unit cavity. The end of the air intake pipe 1101 away from the unit cavity passes through the bottom plate 101 and the protective panel assembly 1 located on the inner side and is connected to the room. The air intake pipe 1101 in the inner cavity 4 is equipped with a first valve 11011. The output end of the fan 1004 is equipped with a second valve 1103. The second valve 1103 is a transfer valve. The output end of the fan 1004 is connected to a circulation pipe 1102 through the second valve 1103. The end of the circulation pipe 1102 away from the second valve 1103 is connected to the air intake pipe 1101 through a third valve 1104. The third valve 1104 is a transfer valve.

[0049] During use, when the external temperature is high, the cooling effect of relying on external gas entering the external ventilation cavity 3 and carrying high-temperature gas outward is generally limited, and the external ventilation cavity 3 will still maintain a relatively high temperature. To avoid excessively high temperatures during the day, when the external temperature drops sharply at night, the temperature inside the external ventilation cavity 3, especially the relatively low-temperature outer side of the aerogel insulation layer 2, will be below the dew point temperature, leading to condensation. The repeated formation and dehumidification of condensation will continuously reduce the insulation performance of the aerogel insulation layer 2 and gradually damage it, causing cracks and breakage, affecting its service life and hindering its reusability. Therefore, a temperature sensor is used to detect the incoming... When the temperature inside the external ventilation cavity 3 reaches the preset high temperature, the sealing process of the ventilation duct 701 is also initiated. Specifically, by increasing the power of the fan 1004 on the main air outlet duct 1002 and increasing the speed of the fan 1004, a negative pressure is generated inside the external ventilation cavity 3. Using the negative pressure inside the external ventilation cavity 3, the connecting plate 704 is attracted to compress the corrugated pipe 703 and bring it close to the ventilation duct 701, completing the connection between the air inlet 7041 of the connecting plate 704 and the sealing column 702, thus sealing the ventilation duct 701. At this time, the internal circulation insulation system 11 is activated. Specifically, by opening the first valve 11011, the external ventilation cavity 3 is connected to the indoor environment. At this time, the third valve 1104 remains closed, and the solenoid valve 1003 on the branch pipe 1001 corresponding to the external ventilation cavity 3 is activated. Keeping open, the solenoid valve 1003 corresponding to the unit cavity with the higher temperature can also be opened individually based on the detection data of multiple unit cavity temperature sensors. The second valve 1103 keeps the output end of the fan 1004 discharging outwards. After the fan 1004 starts, the negative pressure of the fan 1004 draws the low-temperature gas in the room into the unit cavity through the air intake pipe 1101, and moves upward under the action of negative pressure. The end of the air intake pipe 1101 located in the unit cavity corresponds to the middle area of ​​the disturbance blade 804. As the airflow enters the unit cavity and moves upward, it continuously passes through and pushes the disturbance blade 804 to rotate, so that the low-temperature gas in the room enters the unit cavity and is evenly dispersed inside the unit cavity, reducing the temperature inside the unit cavity. Then, it passes through the top... The branch pipe 1001, the main air outlet pipe 1002, and the output end of the fan 1004 discharge outwards. During this process, when the temperature sensor inside the unit cavity detects that the temperature is lower than the preset high temperature threshold, in order to reduce waste, the first valve 11011 is closed, cutting off the connection between the indoor and outdoor ventilation chambers 3. At the same time, the valve on the air intake pipe 1101 corresponding to the high temperature unit cavity is opened, so that the air intake pipe 1101 is connected to the circulation pipe 1102. The second valve 1103 simultaneously disconnects the fan 1004 from the outside and switches to connect with the circulation pipe 1102. At this time, the air intake pipe 1101, the unit cavity, the main air outlet pipe 1002, and the circulation pipe 1102 form the circulation path of the internal circulation insulation system 11. Subsequently, during the operation of the fan 1004,The lower-temperature gas within this circulation path slows down the temperature rise within the unit cavity.

[0050] It is understandable that the activation period of the aforementioned internal circulation insulation system 11, which lowers the temperature inside the unit cavity, is preferably during the transition period from day to night or evening. By lowering the temperature inside the external ventilation cavity 3 in advance, the problem of excessive condensation forming inside the external ventilation cavity 3 due to the large temperature difference between day and night, which could damage the aerogel insulation layer 2, is avoided. When the external humidity is high, the ventilation duct 701 can be sealed in advance by the docking plate 704 before nightfall or evening, based on the monitoring results of the air humidity sensor inside the ventilation duct 701, to reduce the amount of external moisture entering the unit cavity.

[0051] The upper surface of the base plate 101 is below ground level to prevent it from acting as a thermal bridge and continuously transferring heat into the room.

[0052] refer to Figures 12-13 The ventilation duct 701 has a movable groove 7011 on its inner side. The interior of the movable groove 7011 is movably connected to the impeller 801. Specifically, a spring 7012 is installed inside the movable groove 7011, and a bearing is installed on the outer side of the impeller 801. The inner ring of the bearing is fixedly connected to the impeller 801, and the outer ring of the bearing is slidably connected inside the movable groove 7011 and fixedly connected to one end of the spring 7012. In the initial state, the spring 7012 is compressed, and the impeller 801 is located in the movable groove 7011 near the end of the spring 7012. A pressure plate 7042 is provided on the inner side of the mating plate 704. The pressure plate 7042 corresponds to the outer ring of the bearing. During the docking process between the air inlet 7041 and the sealing post 702, the pressure plate 7042 gradually approaches the outer ring of the bearing and pushes the bearing, impeller 801 and disturbance blade 804 to move towards the aerogel insulation layer 2. The disturbance blade 804 is provided with a water-absorbing layer for absorbing moisture in the unit cavity. The water-absorbing layer includes a cotton layer 8041 located on the outside of the disturbance blade 804. By increasing the volume of the cotton layer 8041, the water absorption capacity of the cotton layer 8041 is further increased. When the air inlet 7041 docks with the sealing post 702, the cotton layer 8041 adheres to the side wall of the aerogel insulation layer 2 for scraping and absorbing the condensate layer formed on the side wall of the aerogel insulation layer 2.

[0053] Understandably, the friction between the sealing column 702 and the air inlet 7041 is greater than the restoring force of the spring 7012 and the steel wire spring inside the bellows 703, keeping the sealing column 702 and the air inlet 7041 sealed together, and keeping the disturbance blade 804 close to the side wall of the aerogel insulation layer 2. When the ventilation duct 701 reopens, the fan 1004 supplies air to each unit cavity in reverse order. During the air supply phase, except for the solenoid valve 1003 on the branch pipe 1001 at the top of the unit cavity which is open, all other channels remain closed. By increasing the pressure inside the unit cavity, the sealing column 702 and the air inlet 7041 disengage, and the air pressure pushes the docking plate 704 outward, reopening the ventilation duct 701. At the same time, please refer to... Figures 12-18 A downwardly oriented guide vane 502 is provided on one side of the partition 5 to collect condensed water droplets downwards. An oblique notch 5021 is provided on the side of the guide vane 502 away from the partition 5 to guide the condensed water droplets to collect at the bottom of the guide vane 502. A swing groove 501 is provided on one side of the partition 5. An elastic joint 503 is provided at one end of the guide vane 502. The guide vane 502 is fixedly connected to the inside of the swing groove 501 through the elastic joint 503. There are multiple guide vanes 502. A synchronizing element 504 is provided on the multiple guide vanes 502. The synchronizing element 504 is used for the multiple guide vanes 502 to swing up and down synchronously. The synchronizing element 504 includes a synchronizing rod 5041. A sliding groove 5042 is provided inside the guide vane 502. A steel ball 5043 is provided at the corresponding position of the synchronizing rod 5041 and the guide vane 502. The steel ball 5043 is limited and slidably connected inside the sliding groove 5042.

[0054] The end of the agitator blade 804 furthest from the rotating plate 803 can contact the guide vane 502, which is used to drive the guide vane 502 to swing up and down during rotation. The water-absorbing layer on the agitator blade 804 absorbs the water droplets accumulated on the guide vane 502, thereby removing water droplets from the side wall of the aerogel insulation layer 2 and the partition 5. When the temperature inside the unit cavity rises the next day, the water-absorbing layer on the agitator blade 804 is evaporated by solar energy heating the protective plate assembly 1 and the unit cavity, drying it again and expelling it from the cavity through the main exhaust pipe 1002, ensuring that it has moisture absorption capacity again the following night. Specifically, as shown in the example... Figure 12 and 13As shown, in the initial state, the disturbance blade 804 is located on the side close to the movable slot 7011. At this time, the disturbance blade 804 does not contact the guide vane 502 when rotating. When the external temperature is high, by increasing the power of the fan 1004 on the main air outlet duct 1002, under the action of negative pressure in the unit cavity, the docking plate 704 is attracted to make the sealing column 702 dock with the air inlet 7041, sealing the ventilation duct 701. At the same time, the pressure plate 7042 pushes the outer ring of the outer bearing of the impeller 801 to move towards the rotating plate 803, the spring 7012 is stretched, and the rotating plate 803 and the disturbance blade 804 move towards the aerogel insulation layer 2, so that the cotton layer 8041 adheres to the aerogel insulation layer 2, as shown. Figure 14 As shown, the end of the disturbance blade 804 is simultaneously aligned with the bottommost end of the guide vane 502 near the rotating plate 803, as... Figure 15 and 16 As shown, the first valve 11011 is then opened, connecting the indoor and outdoor ventilation chambers 3. The fan 1004 then draws the low-temperature gas from the indoor space into the unit chamber. The end of the air intake pipe 1101 that connects to the unit chamber corresponds to the middle region of the disturbance blade 804. As the airflow moves upwards, it causes the disturbance blade 804 to rotate counterclockwise around the center point of the bearing. When the disturbance blade 804 contacts one end of the guide vane 502, the water droplets collected at the end of the guide vane 502 are absorbed by the water-absorbing layer on the disturbance blade 804. Figure 16 As shown, the guide vane 502 can be configured as a guide vane group composed of multiple guide vanes 502 of different widths. The two adjacent turbulence sections 8 are a group of guide vanes. The width of the guide vane 502 in each group increases from top to bottom. The guide vane 502 corresponding to the center of the rotating plate 803 has the largest width, so that the water droplets from top to bottom are concentrated on the guide vane 502 corresponding to the center of the rotating plate 803.

[0055] However, there are also smaller water droplets on the guide vane 502. These small water droplets cannot or do not have time to gather at the bottom of the guide vane 502. Under the elastic support of the elastic joint 503 on the guide vane 502, the end of the disturbance blade 804 contacts the bottom of the guide vane 502 and continues to rotate upward. After the end of the disturbance blade 804 passes the guide vane 502, the guide vane 502 rebounds and vibrates due to the rebound action of the elastic joint 503. Furthermore, by setting a synchronous... The component 504 can limit the steel ball 5043 through the sliding groove 5042 when the disturbance blade 804 slides past the end of a guide vane 502, so that multiple guide vanes 502 swing up and down synchronously with the up and down swinging guide vanes 502, thereby accelerating the transfer of small water droplets on the narrower guide vane 502 to the wider guide vane 502. The large coverage of the disturbance blade 804 in the unit cavity allows some small water droplets to be received and absorbed when the guide vane 502 vibrates, as they detach from the disturbance blade 804 due to vibration.
