Description

Technical Field

[0001] The invention relates to a heat insulation device for building and a working method thereof. Background Art

[0002] There are three ways for heat to spread. The first is heat transfer, that is, two objects with a temperature difference are in direct contact. The second is heat convection, and the hotter part in the air or liquid will rise, while the colder part will fall to form a convection cycle. The third is thermal radiation, such as the thermal energy radiation formed by the sun's radiation, which is also the heat energy that the existing curtain wall needs to block or absorb.

[0003] The surface of the roof of existing buildings is mostly waterproof base material patch, which absorbs a large amount of heat energy under the action of thermal radiation, resulting in poor thermal insulation performance of the top floor. In addition, due to the open roof, human activities will cause cracking and damage of waterproof materials, resulting in leakage and further affecting the thermal insulation performance of the building.

The optical thermal insulation film is located in the transparent plate shell and fixed on the lower part of the inner side wall and the inner bottom wall of the transparent plate shell; the transparent plate shell is filled with water; the heat-conducting base is located in the transparent plate shell and fixed on the inner top wall of the transparent plate shell; the heat-conducting sheet is located in the transparent plate shell and fixed on the heat-conducting base, and the heat-conducting sheet is immersed in the water in the transparent plate shell; a pressure valve port is arranged on the top of the transparent plate shell; a driving mechanism is installed in the thermal insulation shell, and includes an electric push rod mechanism, a rack and a gear; the electric push rod mechanism is connected with the rack, the gear is installed on the transparent plate shell, and the rack is meshed with the gear.

[0006] The invention has a hollow opening on the top of the heat-insulating shell and a through groove on the bottom of the heat-insulating shell.

[0007] The present invention provides a plurality of supporting feet for lifting the heat-insulating shell at the bottom of the heat-insulating shell.

[0008] The supporting foot of the present invention comprises a supporting foot column, a screw rod and a rubber pad; the supporting foot column is fixed to the bottom of the heat-insulating shell; the screw rod is installed on the supporting foot column through a thread, and the rubber pad is fixed to the bottom of the screw rod.

[0009] The two ends of the transparent plate shell of the present invention are fixedly provided with rotating shafts and are rotatably mounted on the inner wall of the heat-insulating shell.

[0010] The temperature control plate of the present invention further comprises a matte aluminum-plastic thermal insulation film, and the matte aluminum-plastic thermal insulation film is fixed on the inner side wall of the heat-absorbing coating film.

[0011] In the present invention, a sealing rubber is arranged on the side wall of the temperature control plate, and when the temperature control plate is flipped into place, the sealing contact of adjacent temperature control plates is achieved through the sealing rubber.

[0012] The invention provides an internal pipeline in the heat-insulating shell, the water supply pipeline is connected with the internal pipeline, and the internal pipeline is connected with the transparent plate shell.

[0013] A working method of a heat insulation device for a building, characterized in that it comprises the following steps: (1) Installing the thermal insulation device for a building on the roof surface of the building; (2) In summer, before the sun sets, the electric push rod mechanism drives the rack to move, the rack drives the gear to rotate, and the gear drives the temperature control plate to flip. The temperature control plate rotates to the bottom side facing up, so that the aluminum foil reflective insulation film faces up to reflect most of the heat radiation. The heat radiation that cannot be reflected is absorbed by the water in the temperature control plate; After the sun sets in summer, the water pressure in the water supply pipe is increased to trigger the pressure valve port, and the water in the transparent plate shell is sprayed out from the pressure valve port and scattered to the roof surface; the electric push rod mechanism drives the rack to move, the rack drives the gear to rotate, and the gear drives the temperature control plate to flip, so that the temperature control plate is tilted, and adjacent temperature control plates are not in contact.

[0014] When the natural wind is not strong, the electric push rod mechanism drives the rack to repeatedly drive the temperature control plate to flip back and forth to perform a fanning action, thereby simulating fanning to accelerate the heat absorption and evaporation of water.

[0015] Compared with the prior art, the present invention has the following advantages and effects: 1. The present invention is based on the actual situation of existing buildings. By adding and paving this structure, the thermal insulation performance of the top floor can be improved, and the waterproof material can be quickly and effectively protected without affecting human activities. In addition, the structural construction and paving are simple and convenient, the construction period is short, and the modularization degree is high, which is convenient for maintenance and replacement; 2. The temperature control panel installed inside can be used to control the temperature according to the difference between summer time and winter time; (21) In summer, when the sun is not setting, most of the heat radiation is reflected by turning the aluminum foil reflective insulation film upward. The heat radiation that cannot be reflected is absorbed by the water set in the temperature control panel. The air layer between the temperature control panel and the roof surface is used for isolation, reducing the heat energy transferred from the temperature control panel to the roof of the building. The interior of the building is effectively insulated by blocking heat radiation and slowing down heat transfer. After the sun goes down in the summer, by sprinkling water on the roof, the rapid evaporation of water can be used to absorb heat and increase the efficiency of heat convection, which can quickly, efficiently and cost-effectively cool down the roof, and effectively protect the roof waterproof material from overheating and avoid the risk of water leakage caused by debonding.

[0016] (22) During the daytime in winter, the side where the heat-absorbing coating film is located faces upwards, absorbing heat under the action of the sun's thermal radiation, and the water in the temperature control panel is heated and stored through the action of the heat conductive sheet. Then, at night, it is reversed downwards, so that the air layer between the roof surface and the temperature control panel is locked in, effectively improving the thermal insulation performance, and it still does not affect the normal use of the roof by residents.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and by way of examples. The following examples are intended to explain the present invention but the present invention is not limited to the following examples.

[0019] 1. The heat insulation device for buildings of the embodiment of the present invention comprises a heat insulation shell 10, a support leg 12, a temperature control panel 22 and a driving mechanism. The present invention can be in multiple forms to form a modular structure and laid on the roof of the building.

[0020] The insulation shell 10 is used for packaging and protection and is easy to lay. It can be stepped on by residents and carry human activities and items during use. Hollow openings 11 are arranged at intervals on the top of the insulation shell 10, and through grooves 16 are arranged at intervals on the bottom of the insulation shell 10. The hollow openings 11 are used for light transmission, and the through grooves 16 are used for drainage.

[0021] A plurality of support legs 12 for lifting the insulation shell 10 are provided at intervals at the bottom of the insulation shell 10, thereby forming an air layer that can lock in heat between the temperature control panel 22 and the roof surface, reducing the thermal convection phenomenon in winter and improving the insulation effect. The support legs 12 include support legs 13, screws 14 and rubber pads 15. The support legs 13 are fixed to the bottom of the insulation shell 10; the screws 14 are installed on the support legs 13 through threads, and the rubber pads 15 are fixed to the bottom of the screws 14. In this way, on the one hand, the waterproof layer on the roof can be protected, and on the other hand, the height can be adjusted by rotating the screws 14 to facilitate paving and leveling. At the same time, lowering the height of the device can also effectively reduce the cold wind on the roof surface in winter and thus reduce the cooling caused by thermal convection.

[0022] A cavity is provided in the heat-insulating shell 10, and a temperature control board 22 is integrated in the cavity, so that the temperature control board 22 is integrated in the heat-insulating shell 10. The temperature control board 22 is rectangular, and there are a plurality of them, and the plurality of temperature control boards 22 are arranged side by side in sequence. At the same time, the temperature control board 22 is designed into a small modular structure to facilitate the reduction of the size of the heat-insulating shell 10, and to facilitate production and maintenance, and reduce maintenance and replacement costs. The temperature control board 22 includes a transparent plate shell 23, an aluminum foil reflective heat-insulating film 24, a heat-absorbing coating film 25, a matte aluminum-plastic heat-insulating film 26, a heat-conducting base 27, and a heat-conducting sheet 28.

[0023] The two ends of the transparent plate shell 23 are fixed with a rotating shaft and are rotatably mounted on the inner wall of the heat-insulating shell 10, so that the temperature control board 22 is rotatably mounted in the heat-insulating shell 10. The heat-absorbing coating film 25 is located in the transparent plate shell 23 and is glued and fixed on the upper part of the inner side wall and the inner top wall of the transparent plate shell 23. The aluminum foil reflective insulation film 24 is located in the transparent plate shell 23 and is glued and fixed on the lower part of the inner side wall and the inner bottom wall of the transparent plate shell 23. The aluminum foil reflective insulation film 24 and the heat-absorbing coating film 25 make the heat radiation reflectivity and heat radiation absorption rate of the two sides of the temperature control board 22 different. By turning over, the influence of heat radiation on the top of the building can be controlled. In summer, the temperature control board 22 is rotated to the bottom side facing up, so that the aluminum foil reflective insulation film 24 blocks the heat radiation upward. In winter, the temperature control board 22 is rotated to the top side facing up, so that the heat-absorbing coating film 25 absorbs heat radiation upward during the day to improve the thermal insulation performance of the building.

[0024] The transparent plate shell 23 is also filled with water, and the water absorbs heat radiation to reduce the impact on the building when the temperature is high, and when the external temperature is low, the thermal convection phenomenon at night is reduced through the thermal slow-release insulation of the temperature control plate 22, which effectively improves the temperature locking effect of the building at night in winter. In this embodiment, sodium chloride can be added to the water inside the transparent plate shell 23 to form a supersaturated sodium chloride solution.

[0025] The matte aluminum-plastic insulation film 26 is glued and fixed on the inner side wall of the heat-absorbing coating film 25. The heat-conducting base 27 is located in the transparent plate shell 23 and fixed on the inner top wall of the transparent plate shell 23. The heat-conducting base 27 is attached to the heat-absorbing coating film 25. There are several heat-conducting bases 27, and several heat-conducting bases 27 are arranged side by side in sequence. The heat-conducting sheet 28 is located in the transparent plate shell 23 and fixed on the heat-conducting base 27. The heat-conducting sheet 28 is completely immersed in the water in the transparent plate shell 23. The heat-absorbing coating film 25, the heat-conducting base 27, and the heat-conducting sheet 28 absorb the heat by absorbing the solar heat radiation and then absorb the heat through heat transfer. The matte aluminum-plastic insulation film 26 reduces the heat loss under the convection of the wind before the temperature control plate 22 is reversed. The heat-conducting sheet 28 is made of galvanized aluminum alloy.

[0026] A sealing rubber is embedded in the side wall of the temperature control plate 22. When the temperature control plate 22 is flipped into place, the sealing rubber enables the adjacent temperature control plates 22 to be sealed and contacted to prevent wind from penetrating.

[0027] The driving mechanism is used to drive the temperature control plate 22 to rotate synchronously, thereby adjusting the temperature control plate 22 to face upward with different heat radiation surfaces. The driving mechanism is installed in the heat preservation shell 10 and includes an electric push rod mechanism 20, a rack 17 and a gear 21.

[0028] The electric push rod mechanism 20 is installed in the heat preservation shell 10. The electric push rod mechanism 20 is provided with an electric push rod, a battery and an electric control device for powering the electric control push rod. The electric push rod can also be powered by connecting to the power grid. The telescopic rod of the electric push rod is extended out of the electric push rod mechanism 20 and connected to the rack 17. In this way, the electric push rod mechanism 20 is connected to the rack 17, and the electric push rod mechanism 20 drives the rack 17 to move forward and backward. The gear 21 is fixedly mounted on the rotating shaft at one end of the transparent plate shell 23. The rack 17 is meshed with the gear 21. Under the push of the electric push rod, the rack 17 moves forward and backward, thereby driving the temperature control plate 22 to flip. In one embodiment, the electric push rod mechanism 20 is a waterproof structure, and a waterproof rubber sleeve 19 is fixedly provided on the side wall of the electric push rod mechanism 20, which is used to be mounted on the outside of the electric push rod to prevent water from entering.

[0029] In addition, a pressure valve port 29 is embedded on the top of the transparent plate shell 23, and the pressure valve port 29 is triggered when the set threshold pressure is reached. A water supply pipe for supplying water to the temperature control board 22 is also laid between the roof surfaces of the building, and an internal pipeline 30 is provided in the thermal insulation shell 10, the water supply pipe is connected to the internal pipeline 30, and the internal pipeline 30 is connected to the transparent plate shell 23, so as to realize the connection between the water supply pipe and the transparent plate shell 23. In summer, the water pressure of the water supply pipe is increased so that the water in the transparent plate shell 23 is sprayed out from the pressure valve port 29 and sprinkled on the roof surface, and then the temperature control board 22 is turned over so that the temperature control board 22 is tilted, and the adjacent temperature control boards 22 are not in contact with each other, thereby forming an evaporation port, absorbing heat through the rapid evaporation of water and increasing the efficiency of heat convection, which can quickly, efficiently and at a low cost play a role in cooling, and effectively protect the roof waterproof material from overheating to avoid the potential leakage caused by its debonding. Furthermore, the electric push rod mechanism 20 can repeatedly extend and retract, so that the temperature control plate 22 can be repeatedly turned over to fan the air, thereby accelerating the evaporation of water heat, and combining the principles of heat transfer and heat convection to quickly achieve cooling.

[0030] 2. A working method of a heat insulation device for a building, comprising the following steps: (1) Install the building thermal insulation device on the roof surface of the building.

[0031] (2) In summer, before the sun sets, the electric push rod mechanism 20 drives the rack 17 to move, the rack 17 drives the gear 21 to rotate, and the gear 21 drives the temperature control plate 22 to flip. The temperature control plate 22 rotates to face the bottom upward, so that the aluminum foil reflective insulation film 24 faces upward to reflect most of the heat radiation. The heat radiation that cannot be reflected is absorbed by the water in the temperature control plate 22 and isolated by the air layer between the temperature control plate 22 and the roof surface, thereby reducing the heat energy transferred from the temperature control plate 22 to the roof of the building, and effectively insulating the interior of the building by blocking heat radiation and slowing down heat transfer.

[0032] After the sun sets in the summer, the water pressure in the water supply pipe is increased so that the pressure valve port 29 is triggered when the set threshold pressure is reached, and the water in the transparent plate shell 23 is sprayed out from the pressure valve port 29 and scattered onto the roof surface; the electric push rod mechanism 20 drives the rack 17 to move, the rack 17 drives the gear 21 to rotate, and the gear 21 drives the temperature control plate 22 to flip, so that the temperature control plate 22 tilts downward at an angle of forty-five degrees to open, and adjacent temperature control plates 22 do not contact each other to form an evaporation port, so that natural wind will enter the air layer between the roof surface and the temperature control plate 22 under the guidance of the temperature control plate 22, quickly take away the water vapor, cool the roof surface, and increase the efficiency of heat convection. Since there are usually walls around the roof structure of the building, the natural wind may not be strong. At this time, the electric push rod mechanism 20 drives the rack 17 to repeatedly drive the temperature control plate 22 to flip back and forth to perform fanning action, simulating fanning to accelerate the evaporation of water heat absorption, and combining the principles of heat transfer and heat convection to quickly achieve cooling, so that the temperature of the building wall can be quickly reduced after the sun sets.

[0033] (3) During the daytime in winter, the electric push rod mechanism 20 drives the rack 17 to move, the rack 17 drives the gear 21 to rotate, and the gear 21 drives the temperature control plate 22 to flip. The temperature control plate 22 rotates to the top surface facing upward, so that the heat-absorbing coating film 25 faces upward, absorbs heat under the action of the sun's thermal radiation, and heats the water in the temperature control plate 22 through the action of the heat conductive sheet 28 to store heat energy.

[0034] Then, at night in winter, the electric push rod mechanism 20 drives the rack 17 to move again, so that the heat-absorbing coating film 25 is reversed downward, so that the air layer between the roof surface and the temperature control plate 22 is locked in temperature, which effectively improves the thermal insulation performance without affecting the normal use of the roof by residents.

[0035] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the present invention. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the present invention are included in the protection scope of the patent of the present invention.
