Description

Technical Field

[0001] This invention relates to the technical field of green and energy-saving buildings, and specifically to a double-layer curtain wall structure for green and energy-saving buildings. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall cladding for buildings, hung like a curtain, hence also called a "curtain wall." It is a lightweight wall structure with decorative effects commonly used in modern large and high-rise buildings. It consists of panels and a supporting structural system, and is a building envelope or decorative structure that can have a certain displacement capacity relative to the main structure or a certain deformation capacity, without bearing the main structural load.

[0003] For example, Chinese Patent Publication No. CN119177735B discloses a double-layer curtain wall structure for green and energy-saving buildings. The technical content includes an upper connecting frame, with a guide plate fixedly connected to the bottom of the upper connecting frame. A guide groove is formed through the side wall of the guide plate, and a screw is rotatably connected to the inner wall of the guide groove. A cleaning mechanism is provided on the outer wall of the screw. This double-layer curtain wall structure for green and energy-saving buildings uses a drive motor to move the cleaning mechanism, enabling a scraper to initially remove most of the dust from the outer surface of the curtain wall. Then, a cleaning brush performs a deep cleaning of the outer surface of the curtain wall. Afterward, when the scraper returns to its original position, it dries any water on the outer surface of the curtain wall, preventing water stains from running down due to natural air drying. This effectively completes the cleaning of the outer curtain wall without requiring manual high-altitude cleaning. The cleaning process is simpler, safer, and more efficient.

[0004] However, the above technology has the following drawbacks: Although it uses a motor to drive the cleaning mechanism for cleaning and can achieve better lighting in winter to reduce heating energy, it cannot control the efficiency of internal and external heat exchange and achieve temperature regulation. In addition, existing devices generally use a fresh air system to achieve passive forced exchange, which cannot achieve energy recovery well and cannot actively flow gas, thereby increasing the use of energy in the entire room and increasing energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide a double-layer curtain wall structure for green and energy-saving buildings to overcome the above-mentioned defects in the prior art.

[0006] A double-layer curtain wall structure for a green and energy-saving building includes a mounting frame, on both sides of which glass is installed.

An upper breathing box and a lower breathing box are respectively provided on the upper and lower sides of the mounting frame. The upper breathing box is connected to a ventilation pipe connected to the hollow panel. A circulation mechanism connected to the hollow panel is provided in the connecting frame.

[0010] Preferably, the filter assembly includes a replacement box disposed inside the filter box, the bottom of the replacement box is provided with a through hole, one end of the vent pipe extends into the gap between the replacement box and the filter box, and the replacement box is filled with filter material.

[0011] Preferably, filter cotton is filled between the filter box and the replacement box, and a connecting rod connects two adjacent replacement boxes, with the connecting rod on one side contacting the inspection plate.

[0016] The beneficial effects achieved by this invention are as follows: This application utilizes the principle of air pressure differences caused by temperature changes to achieve autonomous ventilation and forced ventilation via a circulation pump. During ventilation, the system simultaneously undergoes heat exchange, reducing temperature loss while refreshing the internal air, thus constructing an energy-efficient and comprehensive protection system. Furthermore, this application uses solar panels to reduce dependence on internal electricity and creates a near-vacuum or non-vacuum state between the two layers of glass via a circulation pump, effectively blocking direct or rapid heat exchange with the outside environment. This system can adapt to various environmental operating requirements, reduce indoor energy loss, and improve energy utilization efficiency. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example 1 like Figures 1 to 8 As shown, an embodiment of the present invention provides a double-layer curtain wall structure for a green and energy-saving building, including a mounting frame 1. Glass is installed on both sides of the mounting frame 1, and a connecting frame 6 connects the two mounting frames 1. The glass on both sides can isolate the interior and exterior spaces while allowing light to enter. The connecting frame 6 connects and stabilizes the two mounting frames 1, enabling the installation and use of the entire glass curtain wall. Hollow panels 2 are fixedly connected to both sides of the mounting frame 1. A lower breathing chamber 4 and an upper breathing chamber 9 are respectively connected to both sides of the mounting frame 1. The lower breathing chamber 4 is located at the bottom, and the upper breathing chamber 9 is located at the top of the glass. Both the lower breathing chamber 4 and the upper breathing chamber 9 are equipped with… There are two chambers, one connected to the outside space and the other connected to the indoor space. The upper breathing chamber 9 is connected to a ventilation tube 16 that is connected to the hollow plate 2. A circulation mechanism is set inside the connecting frame 6. The circulation mechanism is connected to the hollow plate 2. Through the circulation mechanism and the conduction of the lower breathing chamber 4, the upper breathing chamber 9 and the hollow plate 2, the flow and exchange of internal and external gases can be realized to ensure the cleanliness of the room. Both the lower breathing chamber 4 and the upper breathing chamber 9 are hollow, and each of the lower breathing chamber 4 and the upper breathing chamber 9 has a vent on one side. The vent has a guide strip connected to the corresponding lower breathing chamber 4 or upper breathing chamber 9 for guiding the flow of gas.

[0023] A sealing plate 3, which is fixedly connected to the hollow plate 2, is provided between the two lower breathing chambers 4 at the bottom. A top plate 7 is fixedly connected to the top of the mounting frame 1. The sealing plate 3 circulation mechanism isolates the space enclosed by the two glass panels and the mounting frame 1. The top plate 7 increases the overall strength of the mounting frame 1 and works with the sealing plate 3 to achieve spatial isolation, thus obtaining a separate space inside the glass.

[0024] The working principle is as follows: In use, multiple mounting brackets 1 are connected horizontally, and corresponding connecting frames 6 are installed on the mounting brackets 1. Then, mounting brackets 1 are installed on the connecting frames 6 and stacked. The thickness of the connecting frames 6 is selected according to the thickness of the support layer of each floor of the building, and the height of the mounting brackets 1 is selected based on the indoor height. The curtain wall is installed by splicing multiple mounting brackets 1 and connecting frames 6. Then, a circulation mechanism is installed in the connecting frames 6 and connected to the hollow panel 2. When the power is turned on, the circulation mechanism realizes the circulation and exchange of internal and external gases.

[0025] Example 2 like Figures 1 to 8 As shown in Example 1, another embodiment of the present invention is as follows: The circulation mechanism includes a maintenance plate 10 connected to the inner side of the connecting frame 6. A drive assembly is connected to one side of the maintenance plate 10, and one end of the drive assembly extends between the two glass panes. Four filter boxes 20 are fixedly connected inside the connecting frame 6, distributed around the perimeter of the connecting frame 6. Each filter box 20 contains a filter assembly that filters the circulating gas, reducing the entry of particulate matter and dust into the room and ensuring gas cleanliness. A second vent pipe 13 is connected to the bottom of each filter box 20, and the other end of the second vent pipe 13 extends... Inside the hollow panel 2, the filter box 20 is also connected to a ventilation pipe 12. The other end of the ventilation pipe 12 is connected to the lower breathing box 4 located at the bottom. The control box 14 is connected inside the connecting frame 6. Gas is connected to the hollow panel 2 and the filter box 20 through the second ventilation pipe 13, thereby connecting the filter box 20 to the upper breathing box 9 at the top. The ventilation pipe 12 connects the lower breathing box 4 and the ventilation pipe 12, realizing the conduction of another outlet. The drive component can also extract the gas between the two glass panels, reducing the energy exchange due to the large temperature difference between the inside and outside.

[0026] The drive assembly includes a circulation pump 11 fixedly connected to the inspection plate 10. The output end of the circulation pump 11 is connected to a hose, and the other end of the hose is connected to a vertical pipe 21. The top of the vertical pipe 21 is connected to an extension pipe 15 extending to the outside of the sealing plate 3. Through the operation of the circulation pump 11, the gas between the glass can be extracted after passing through the extension pipe 15, the vertical pipe 21 and the hose, reducing energy exchange. At the same time, high-pressure gas can be filled to increase temperature exchange, so that the room can be quickly cooled or heated through heat exchange, thereby reducing the use of refrigeration and heating devices. The bottom of the vertical pipe 21 is connected to a support column connected to the hose. A branch pipe connected to the filter box 20 is connected to the vertical pipe 21. Through the branch pipe connected to the filter box 20, the internal gas can be forced to flow through the filter box 20, and then through the hollow plate 2, the upper breathing box 9 or the lower breathing box 4 for forced gas flow and forced gas exchange.

[0027] The filter assembly includes a replacement box 24 disposed inside the filter box 20. The bottom of the replacement box 24 is provided with a through hole 25. One end of the vent pipe 12 extends into the gap between the replacement box 24 and the filter box 20. The replacement box 24 is filled with filter material. When gas enters and exits the replacement box 24 through the vent pipe 23, it can be filtered by the internal filter material to reduce the passage of some pollutants. At the same time, the through hole 25 at the bottom is open, so that the gas must move in a certain direction and flow through the vent pipe 12.

[0028] The filter box 20 and the replacement box 24 are filled with filter cotton. A connecting rod 23 is fixedly connected between two adjacent replacement boxes 24. The connecting rod 23 on one side is in contact with the inspection plate 10. Secondary filtration is performed through the filter cotton to ensure the cleanliness of the gas. The two replacement boxes 24 can be connected by the connecting rod 23, which facilitates the replacement and cleaning of the materials in the replacement box 24 and the filter box 20.

[0029] Working principle: During operation, external air enters the hollow plate 2 through the top upper breathing chamber 9, then passes through the second ventilation pipe 13 into the replacement chamber 24 in the diagonally opposite lower breathing chamber 4 for filtration, and then passes through the first ventilation pipe 12 into the lower breathing chamber 4 for discharge, thus achieving air intake. On the other side, the air enters the hollow plate 2 through the upper breathing chamber 9, then passes through the second ventilation pipe 13 into the replacement chamber 24 in the diagonally opposite lower breathing chamber 4 for filtration, and then passes through the first ventilation pipe 12 into the lower breathing chamber 4 for discharge, achieving circulation of internal and external air while ensuring air cleanliness. At the same time, the forced operation of the circulation pump 11 can achieve forced air flow and forced air exchange. Simultaneously, the operation of the circulation pump 11 can draw air between the two glass panes through the extension pipe 15, reducing the exchange of internal and external temperatures and saving energy.

[0030] Example 3 like Figures 1 to 8 As shown in Example 1, another embodiment of the present invention is as follows: A series pipe 28 is connected between the two filter boxes 20, and the two ends of the series pipe 28 are located in the filter boxes 20 on both sides respectively. An auxiliary pipe connected to the input end of the circulation pump 11 is connected to one side of the series pipe 28. A solenoid valve is connected to the series pipe 28, which can control the conduction between the two filter boxes 20 to adapt to different working needs. At the same time, the filter box 20 can be directly connected to the circulation pump 11 through the series pipe 28 via the auxiliary pipe to ensure the needs of subsequent forced ventilation.

[0031] A supplementary plate 30 is fixedly connected to the bottom of the control box 14. The two sides of the supplementary plate 30 are fixedly connected to the filter box 20. A battery 22 located in the connecting frame 6 is also provided on one side of the supplementary plate 30. The supplementary plate 30, together with the control box 14, isolates the internal space of the connecting frame 6 from the top, further preventing the uncontrolled flow of gas between the two glass panes. The battery 22 temporarily stores electricity. A controller 17 is also provided inside the control box 14. The controller 17 is existing technology and can control the solenoid valve and other electrical components.

[0032] The hollow panel 2 has two non-communicating hollow cavities 18. A metal column 19 fixedly connected to the hollow panel 2 is provided between the two hollow cavities 18 located in the same hollow panel 2. The hollow cavity 18 can divide the hollow panel 2 into two spaces, realizing the separation of air intake and exhaust. The metal column 19 is made of metal, which can quickly transfer heat, so that heat is exchanged when exchanging gases, reducing the energy consumption of subsequent indoor devices.

[0033] A fixing rod 27 is connected to one side of the connecting frame 6, and a solar panel 8 connected to the connecting frame 6 is connected to the other end of the fixing rod 27. The solar panel 8 is connected to the battery 22 through wires. The solar panel 8 uses solar energy to generate electricity for its own control, thereby reducing energy consumption.
