Description

Technical Field

[0001] This invention relates to the field of building-related technologies, and more particularly to the field of building curtain wall technologies, specifically a building decorative energy-saving curtain wall. Background Technology

[0002] A building curtain wall is a decorative wall that is suspended and fixed to the outside of the main body of a building, like a curtain. As the external enclosure structure of the main body of the building, although it does not bear the load of the main structure of the building, it plays an indispensable role in safety protection, energy conservation and environmental protection and urban image shaping. Building curtain walls are mainly composed of panels and supporting structural systems. The two are complementary. The panels, as the outer surface material of the curtain wall, directly face the external environment and affect the appearance and performance of the building. The supporting structural system is used to fix the panels and transfer the panel load to the main body of the building.

[0003] For example, Chinese patent CN114150801B discloses an external circulation breathing double-layer curtain wall, including a support component, several unit curtain wall components installed on the support component, and a ventilation component. The support component includes an outer support, an inner support, and several vertical beams. The unit curtain wall components include an inner wall, an outer wall, and connectors. The inner wall is placed on the inner support, and the outer wall is placed on the outer support. A ventilation channel is formed between the inner wall and the outer wall. The ventilation component is installed on the outer support.

[0004] Based on the aforementioned patents, existing solutions, and practical application, current energy-saving curtain walls still have some problems, such as: The aforementioned patent describes a ventilation channel between the inner and outer walls. The ventilation component, which includes an air inlet grille and an air outlet grille, is mounted on the outer support. The ventilation component and the ventilation channel work together to replace the airflow within the ventilation channel. The ventilation component cannot be adjusted to open or close, ensuring that the ventilation channel remains open at all times. Similar to existing double-glazed curtain walls, these walls also have ventilation channels on the top and bottom that cannot be opened or closed. These ventilation channels are a single-mode system that is always open, which cannot effectively regulate heat exchange. When dealing with different weather conditions, this reduces the advantages of energy saving and environmental adaptability. For example, in cold seasons, the open ventilation channels cannot meet the needs of heat preservation.

[0005] Therefore, we propose an energy-saving curtain wall for building decoration to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving curtain wall for building decoration, so as to solve the problem mentioned in the background art that the inability to effectively regulate heat exchange reduces environmental adaptability and affects energy saving when dealing with different meteorological environments.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving curtain wall for building decoration, comprising: The keel frame is composed of vertical keels and horizontal bracing keels assembled together; Also includes: An inner glass curtain wall is provided, with an outer glass curtain wall arranged parallel to the front of the inner glass curtain wall. Both the inner and outer glass curtain walls are housed within a keel frame. The dynamic sealing frame integrated on the outer glass curtain wall is slidably inserted into the static sealing frame integrated on the inner glass curtain wall. The combination of the dynamic and static sealing frames forms an air channel for regulating heat exchange. The shell frame is fixed to the cross bracing keel in the keel frame and is fixed to the inner glass curtain wall. The shell frame is equipped with a drive component that can drive the outer glass curtain wall to slide open and close. The outer glass curtain wall drives the dynamic sealing frame to move synchronously, and adaptively regulates the opening and closing of the air channel.

[0008] Preferably, the outer glass curtain wall has holes at equal intervals on both the upper and lower sides, and the holes are corresponding to the slots on the static sealing frame. The slots are arranged symmetrically about the horizontal central axis of the static sealing frame. The slots and holes are used for air passages to connect with the outside. The slots can be blocked by the static sealing frame to form a seal.

[0009] Preferably, the drive assembly includes a first bracket and a second bracket arranged in a cross configuration, and is equipped with an active pusher for driving the two brackets to extend or fold. The outward end of the first bracket is rotatably connected to the outer glass curtain wall, and the inward end of the first bracket is rotatably connected to the active pusher. The middle part of the first bracket is rotatably connected to the middle part of the second bracket. The outward end of the second bracket forms a sliding structure within the outer glass curtain wall, and the inward end of the second bracket is rotatably connected to the shell frame.

[0010] Preferably, the active push block forms a sliding structure within the shell frame, and a connecting rod is slidably connected within the active push block, with a first spring installed at the sliding connection point. The connecting rod is assembled with an electric telescopic rod fixed within the shell frame, and the connecting rod forms a sliding structure within the shell frame under the drive of the electric telescopic rod.

[0011] Preferably, a positioning pin for locking between the connecting rod and the active push block is provided at the sliding connection point. The positioning pin forms a telescopic sliding structure within the active push block, and a second spring is installed at the sliding connection point. The pin head is connected to the connecting rod by a snap-fit ​​method, and the pin tail is connected to the unlocking groove opened in the shell plate frame by a sliding pressing method.

[0012] Preferably, the left and right sides of the shell frame are provided with a ventilation mechanism that can be controllably adjusted to open or close. The ventilation mechanism includes a ventilation pipe frame fixed to the vertical keel in the keel frame, an arc-shaped baffle integrated in the ventilation pipe frame, and an arc-shaped filter plate assembled at the ventilation hole in the arc-shaped baffle. The front and rear sides of the ventilation pipe frame are respectively provided with an air inlet slot and an air outlet. Fresh air is collected and delivered to the room through the ventilation pipe frame, and impurities in the fresh air are filtered through the arc-shaped filter plate. The arc center of the arc-shaped baffle is set eccentrically to the center of the ventilation pipe rack, and the cavity of the ventilation pipe rack is set in a vortex shape by the arc-shaped baffle.

[0013] Preferably, the ventilation duct frame is provided with a sealing plate for sealing the air inlet slot. The sealing plate forms a flip structure on the ventilation duct frame, and a torsion spring is installed at the flip connection between the two. An integrated lever part is inclinedly provided on the sealing plate, and the lever part is connected to the driven push block in a sliding manner. The driven push block forms a sliding structure within the shell frame, and a third spring is installed at the sliding connection between the two. The driven push block and the connecting rod are connected by a pressing and pushing method.

[0014] Preferably, a connecting plate for shielding is provided at the gap formed between the ventilation pipe frame and the outer glass curtain wall.

[0015] Preferably, the cleaning holes in the ventilation duct frame are sequentially connected to the cleaning holes in the shell plate frame and the keel frame. The ventilation duct frame is provided with a cleaning ball that can fit against the arc-shaped filter plate. The cleaning ball moves through the cleaning holes in the ventilation duct frame, the shell plate frame, and the keel frame in sequence. By pulling the cleaning ball, the debris accumulated on the arc-shaped filter plate can be scraped and cleaned.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: the building decoration energy-saving curtain wall can adapt to different meteorological environments, effectively regulate heat exchange, reduce mechanical ventilation energy consumption, and achieve energy saving by utilizing natural forces; 1. The dynamic sealing frame is movably inserted into the static sealing frame, forming an air channel between the outer and inner glass curtain walls. When the outer glass curtain wall slides open or closes, it drives the dynamic sealing frame to move synchronously, adjusting the dynamic sealing frame to block or allow the air to pass through the openings, thus realizing the opening and closing of the air channel. In response to different meteorological environments, unlike the existing single open state mode of air channels, it can adaptively adjust the opening and closing of the air channel, enabling the air channel to effectively regulate heat exchange, thereby improving environmental adaptability. 2. The ventilation duct frame is equipped with air inlets and air outlets on the front and rear sides, respectively. The ventilation duct frame achieves natural ventilation, reduces the energy consumption of mechanical ventilation, and saves energy by utilizing natural forces. The air inlets of the ventilation duct frame are equipped with sealing plates for sealing. The sealing plates are driven by the linkage of the drive components and can be adjusted to open and close on the ventilation duct frame. Through controllable adjustment, the state can be freely switched to meet different indoor needs and better cope with changes in outdoor weather conditions. In addition, the two ventilation mechanisms can also be opened independently to cope with different outdoor wind directions. Furthermore, the ventilation duct frame is equipped with an integrated arc-shaped baffle. The arc-shaped baffle makes the cavity of the ventilation duct frame vortex-shaped, which makes it easier for the arc-shaped filter plate to capture impurities mixed in the fresh air and improve filtration efficiency. In addition, the arc-shaped filter plate and the cleaning ball are connected in a close fit. By pulling, it is easy to clean the impurities accumulated on the arc-shaped filter plate. The ventilation duct frame also facilitates the discharge of the cleaned impurities, improving the ease of operation. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This invention provides a technical solution: an energy-saving curtain wall for building decoration. When dealing with different meteorological environments, a single-mode ventilation channel cannot effectively regulate heat exchange, reducing environmental adaptability. By driving the outer glass curtain wall 3 through the drive component 7, the opening and closing of the air channel formed by the combination of the dynamic sealing frame 4 and the static sealing frame 5 can be adaptively controlled, so that the air channel can effectively regulate heat exchange.

[0021] This technical solution: Please refer to Figures 1-6An energy-saving curtain wall for building decoration includes a keel frame 1, which is composed of vertical keels and horizontal bracing keels. The connection between the vertical keels and horizontal bracing keels is made by cross connectors for a stable overlap. That is, the cross connectors are reliably connected at the intersection of the vertical keels and horizontal bracing keels to form a grid-like load-bearing system, which improves the overall stability of the structure. In addition, the cross connectors are assembled with the vertical keels and horizontal bracing keels by inserting them and then fixing them together with bolts. The standardized assembly settings enable quick assembly and disassembly, ensuring convenient construction. It also includes an inner glass curtain wall 2 and a shell frame 6. An outer glass curtain wall 3 is arranged parallel to the front of the inner glass curtain wall 2. Both the inner glass curtain wall 2 and the outer glass curtain wall 3 are installed in the keel frame 1. The dynamic sealing frame 4, which is integrated on the outer glass curtain wall 3, and the static sealing frame 5, which is integrated on the inner glass curtain wall 2, are slidably inserted together. The dynamic sealing frame 4 and the static sealing frame 5 are combined to form an air channel for regulating heat exchange. The shell frame 6 is fixed to the cross brace in the keel frame 1 and is fixed to the inner glass curtain wall 2. The shell frame 6 is provided with a drive component 7 that can drive the outer glass curtain wall 3 to slide open and close. The outer glass curtain wall 3 drives the dynamic sealing frame 4 to move synchronously, adaptively regulating the opening and closing of the air channel.

[0022] Specifically, in this technical solution, the outer glass curtain wall 3 is slidably opened and closed by the drive component 7, according to... Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the keel frame 1 has a grid-like structure with a grille frame. The shell plate frame 6 is horizontally set between the outer glass curtain wall 3 and the inner glass curtain wall 2. It is mirrored about the horizontal central axis of the outer glass curtain wall 3. The upper and lower shell plate frames 6 correspond to the upper and lower horizontal braces of the grille frame in the keel frame 1. The shell plate frame 6 has an integrated assembly block part protruding from the side facing the horizontal brace of the keel frame 1. The assembly blocks are set at equal intervals on the shell plate frame 6. After the shell plate frame 6 is installed, it fits and overlaps with the horizontal brace of the keel frame 1. The assembly blocks are snapped into the horizontal brace of the keel frame 1 and are fixedly connected to the horizontal brace of the keel frame 1 by bolts. Since the connecting rod 13 is set in a nail-like structure, the end facing the active push block 12 is the nail head end, and the other end is the nail tail end. Since the electric telescopic rod 15 is installed in the shell cavity of the shell plate frame 6 by bolts, and its output end is inserted into and fixedly connected to the nail tail end of the connecting rod 13 by bolts, the electric telescopic rod 15 is started to extend and operate, driving the connecting rod 13 to slide within the shell plate frame 6. Since the sliding connection between the connecting rod 13 and the active push block 12 is provided with a positioning pin 16 for locking between the two, that is, in the initial state, the connecting rod 13 is locked on the active push block 12, and when the connecting rod 13 is driven to slide, it drives the active push block 12 to move synchronously. Since the active push block 12 has an integrated support leg on the side facing the first support 10, after the active push block 12 is installed, it is movably locked in the shell cavity of the shell plate frame 6 along with the support leg. Through the square structure characteristics of the active push block 12 itself and the limiting assistance of its support leg, the active push block 12 is positioned in the shell cavity of the shell plate frame 6 in a movable state. It is restricted to linear sliding only. The active push block 12 moves synchronously with the connecting rod 13, so that it slides in the shell cavity of the shell plate frame 6. Since the end of the first bracket 10 facing the outer glass curtain wall 3 is the outward end, and the end facing the shell frame 6 is the inward end, a shaft is movably inserted into the outward end of the first bracket 10. A bearing is installed at the connection between the shaft and the first bracket 10. After the first bracket 10 is installed, its outward end is movably inserted into the groove of the outer glass curtain wall 3, and the shaft on the outward end is inserted into and fixed to the groove wall of the outer glass curtain wall 3 by bolts. This allows the outward end of the first bracket 10 to be supported by the shaft on the outer glass curtain wall. The first support 10 has a rotating structure, and since the inward end of the first support 10 is movably inserted with a shaft column, and a bearing is installed at the connection between the shaft column and the first support 10, after the first support 10 is connected to the active push block 12, the inward end of the first support 10 is movably locked in the groove cavity of the support leg of the active push block 12, and the shaft column on the inward end is inserted and fixedly connected to the groove cavity wall of the support leg of the active push block 12 by bolts, so that the inward end of the first support 10 forms a rotating structure on the support leg of the active push block 12 with the assistance of the shaft column thereon. Since the end of the second bracket 11 facing the outer glass curtain wall 3 is the outward end, and the end facing the shell frame 6 is the inward end, a shaft is movably inserted into the inward end of the second bracket 11. A bearing is installed at the connection between the shaft and the second bracket 11. After the second bracket 11 is installed, its inward end is movably inserted into the shell cavity of the shell frame 6, and the shaft on the inward end is inserted into and fixed to the shell cavity wall of the shell frame 6 by bolts, so that the inward end of the second bracket 11 is assisted by the shaft on it. The shell frame 6 forms a rotating structure. The outward end of the second bracket 11 is inserted and fixedly connected to a shaft column by bolts. A bearing is installed on the shaft column. After the second bracket 11 is installed, its outward end is movably inserted into the groove of the outer glass curtain wall 3. The shaft column on the outward end, together with the bearing, is movably locked in the sliding groove on the groove wall of the outer glass curtain wall 3. This allows the outward end of the second bracket 11 to form a sliding structure in the groove of the outer glass curtain wall 3 with the assistance of the shaft column. Since the outward ends of the first bracket 10 and the second bracket 11 are on the same horizontal central axis, and the inward ends of the first bracket 10 and the second bracket 11 are also on the same horizontal central axis, and since the specifications and dimensions of the first bracket 10 and the second bracket 11 are the same, bearings are snap-fitted into the middle of both the first bracket 10 and the second bracket 11. A shaft is movably inserted into the bearing in the middle of the first bracket 10, and the shaft in the middle of the first bracket 10 movably passes through the bearing in the middle of the second bracket 11, so that the first bracket... The first support 10 is rotatably connected to the second support 11 through the central column. The first support 10 and the second support 11 are arranged in an "X" shape. Based on the mechanical motion structure of the cross-link hinge, when the active push block 12 is driven to slide in the shell cavity of the shell plate frame 6, it pushes the inward end of the first support 10 to move. Through the linkage of the hinge point of the cross link, the included angle between the first support 10 and the second support 11 is reduced, and the first support 10 and the second support 11 extend and smoothly push the outer glass curtain wall 3. Since the inner glass curtain wall 2 is embedded in the grid frame of the keel frame 1, the upper and lower sides of the inner glass curtain wall 2 are respectively fixed to the rear side walls of the upper and lower shell frame 6 by bolts. Since the outer glass curtain wall 3 is also embedded in the grid frame of the keel frame 1 and is parallel to the inner glass curtain wall 2, when the outer glass curtain wall 3 is pushed, the outer glass curtain wall 3 slides smoothly and unfolds relative to the inner glass curtain wall 2 within the grid frame of the keel frame 1. Based on the above, the electric telescopic rod 15 is activated to retract and operate, driving the connecting rod 13 to perform a reset movement within the shell cavity of the shell frame 6. Utilizing the locking action of the positioning pin 16, the connecting rod 13 drives the active push block 12 to synchronously reset and slide within the shell cavity of the shell frame 6, pulling the inward end of the first bracket 10 to move, increasing the angle between the first bracket 10 and the second bracket 11, and causing the first bracket 10 and the second bracket 11 to fold, smoothly pulling the outer glass curtain wall 3 to slide and close within the grid frame of the keel frame 1.

[0023] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 5 As shown, since the drive components 7 are mirror images of the vertical central axis of the shell frame 6, that is, the four drive components 7 are respectively arranged at the top, bottom, left and right corners of the outer glass curtain wall 3. By pushing and pulling the drive components 7, the outer glass curtain wall 3 is driven to slide open or slide close relative to the inner glass curtain wall 2, so that the load of the outer glass curtain wall 3 can be evenly distributed on the four drive components 7, thereby improving the overall stability.

[0024] Meanwhile, in the above technical solutions, according to Figure 1 , Figure 3 and Figure 4 As shown, after the outer glass curtain wall 3 is installed, its upper and lower side walls are respectively connected to the upper and lower horizontal braces of the grid frame in the keel frame 1. The contact size between the outer glass curtain wall 3 and the horizontal braces in the keel frame 1 is greater than the maximum sliding distance of the outer glass curtain wall 3. When the outer glass curtain wall 3 is fully slid out, the outer glass curtain wall 3 will not detach from the horizontal braces in the keel frame 1. This allows the outer glass curtain wall 3 in the fully slid out state to still be supported by the keel frame 1, which can more effectively bear the wind load and ensure the stability of the overall structure. In addition, it avoids the formation of gaps between the outer glass curtain wall 3 and the horizontal braces in the keel frame 1 after the outer glass curtain wall is fully slid out, preventing debris from entering and affecting the drive component 7.

[0025] Meanwhile, in the above technical solutions, according to Figure 1 As shown, photovoltaic panels are embedded and fixed to the outer left and right sides of the outer glass curtain wall 3 with bolts. Integrating the photovoltaic panels into the outer glass curtain wall 3 can convert solar energy into electrical energy, which can provide power to the drive component 7 independently or be connected to the building power grid.

[0026] Specifically, in this technical solution, the air passage formed by the combination of the dynamic sealing frame 4 and the static sealing frame 5 is opened or closed according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since the side of the outer glass curtain wall 3 facing the inner glass curtain wall 2 is the inward side, and the other side is the outward side, the dynamic sealing frame 4 has a square frame structure and is integrated into the inward side of the outer glass curtain wall 3. Since the side of the inner glass curtain wall 2 facing the outer glass curtain wall 3 is the inward side, and the other side is the outward side, the static sealing frame 5 has a square frame structure and is integrated into the inward side of the inner glass curtain wall 2. After the outer glass curtain wall 3 and the inner glass curtain wall 2 are connected, the dynamic sealing frame 4 is movably inserted into the static sealing frame 5. The frame walls of the two are fitted together. Through the mutual cooperation between the dynamic sealing frame 4 and the static sealing frame 5, an air channel is formed between the outer glass curtain wall 3 and the inner glass curtain wall 2. Because the upper and lower side walls of the static sealing frame 5 are provided with through-holes 9, and the upper and lower sides of the outer glass curtain wall 3 are provided with through-holes 8 at equal intervals, the through-holes 8 and the through-holes 9 are arranged correspondingly. The through-holes 9 and the through-holes 8 are used to connect the outside to the air. Since the width of the through-holes 9 is smaller than the depth of the dynamic sealing frame 4 inserted into the static sealing frame 5, when the outer glass curtain wall 3 is in the closed state, the dynamic sealing frame 4 does not slide within the static sealing frame 5. At this time, the frame of the dynamic sealing frame 4 blocks the strip hole 9 in the static sealing frame 5, thus closing the air passage. Conversely, when the outer glass curtain wall 3 is in the unfolded state, the outer glass curtain wall 3 drives the dynamic sealing frame 4 to move synchronously, causing the dynamic sealing frame 4 to slide within the static sealing frame 5. At this time, the frame of the dynamic sealing frame 4 loses its blocking effect on the strip hole 9. Through the strip hole 9 and the hole 8, the air passage is connected to the outside, thus opening the air passage. Because the air passage can be adaptively opened and closed, it can be used to regulate heat exchange. As mentioned above, when the air passage is closed, in winter, sunlight shines through the outer glass curtain wall 3 into the air passage, warming the air inside. The warmed air layer acts as insulation, reducing heat loss from the room and thus reducing heating energy consumption. In summer, when the air passage is open, it utilizes the principle that hot air rises naturally due to its lower density. The lower opening 8 in the outer glass curtain wall 3 serves as the air inlet, and the upper opening 8 serves as the air outlet. Sunlight shines through the outer glass curtain wall 3 into the air passage, warming the air inside. The warmed air is discharged outward from the upper opening 8, while the lower opening 8 draws in cooler outside air, creating natural convection that carries away heat, thereby reducing cooling energy consumption.

[0027] Meanwhile, in the above technical solutions, according to Figure 3 and Figure 4 As shown, the dynamic sealing frame 4 follows the outer glass curtain wall 3 to form a synchronous sliding structure, so that the dynamic sealing frame 4 forms a sliding structure within the static sealing frame 5. The depth of the dynamic sealing frame 4 inserted into the static sealing frame 5 is greater than the maximum sliding distance of the dynamic sealing frame 4. After the dynamic sealing frame 4 has completely slid along with the outer glass curtain wall 3, the dynamic sealing frame 4 and the static sealing frame 5 still remain in the inserted state, maintaining the air passage between the outer glass curtain wall 3 and the inner glass curtain wall 2.

[0028] Specifically, in this technical solution, the drive component 7 performs a linkage operation according to... Figure 5 and Figure 6As shown, the end of the positioning pin 16 closest to the connecting rod 13 is the pin head end, and the other end is the pin tail end. The pin tail end is hemispherical. A second spring 17 is installed at the connection between the positioning pin 16 and the active push block 12. After the second spring 17 is installed, it is movably sleeved outside the positioning pin 16. One end of the spring 17 presses against the limiting plate in the positioning pin 16, and the other end presses against the active push block 12. Since the positioning pin 16 has an integrated limiting plate that is radially extended in the middle, after the positioning pin 16 is installed, it is movably inserted into the active push block 12 along with the limiting plate. The pin head end is movably inserted into the groove of the active push block 12, and the pin tail end is movably inserted through the active push block 12 and extends outward, so that the positioning pin 16 is movably positioned in the active push block 12. Since the end of the unlocking groove 18 closest to the active push block 12 is the head end, and the other end is the tail end, and the tail end of the unlocking groove 18 is recessed and has an unlocking hole, and since the unlocking groove 18 is opened in the shell plate frame 6, after it is connected with the positioning pin 16, the hemispherical pin tail end of the positioning pin 16 is movably inserted into the unlocking groove 18 and forms a sliding structure in the unlocking groove 18. When the active push block 12 is not sliding and is in the initial state, the hemispherical pin tail end of the positioning pin 16 presses against the head end of the unlocking groove 18. At this time, the positioning pin 16 is pushed and is in a sliding extension state, and the second spring 17 is compressed and undergoes elastic deformation. Furthermore, the pin head end of the positioning pin 16 is engaged with the connecting rod 13, so that the connecting rod 13 and the active push block 12 are in a locked state. When the connecting rod 13 initially moves, the locking action of the positioning pin 16 drives the active push block 12 to slide synchronously, so that the hemispherical end of the positioning pin 16 slides along the unlocking groove 18 towards the end of the unlocking groove 18. At this time, the positioning pin 16 and the connecting rod 13 are in an engaged state. When the active push block 12 slides with the connecting rod 13, the outer glass curtain wall 3 is fully slid out. At this time, the active push block 12 has not yet completely slid in the shell cavity of the shell plate frame 6. That is, the hemispherical pin tail of the positioning pin 16 has not yet slid to the unlocking hole of the unlocking groove 18. The positioning pin 16 is still engaged with the connecting rod 13. Since the depth of the unlocking hole in the unlocking groove 18 is equal to the maximum sliding distance of the positioning pin 16, when the connecting rod 13 drives the active push block 12 to slide completely, the active push block 12 is restricted and pressed against the shell cavity wall of the shell plate frame 6. At this time, the active push block 12 cannot slide. The hemispherical pin tail of the positioning pin 16 corresponds to the unlocking hole at the tail end of the unlocking groove 18. The elastic deformation of the second spring 17 is used to reset the positioning pin 16, which drives the positioning pin 16 to automatically retract and slide in the active push block 12. That is, the positioning pin 16 is released from the locking action with the connecting rod 13, and the unlocking process between the connecting rod 13 and the active push block 12 is carried out. This does not hinder the continuous movement of the connecting rod 13 and its sliding in the active push block 12. Because the nail head end of the connecting rod 13 extends outward through the active push block 12 after the rod is installed, and because a first spring 14 is installed at the sliding connection between the active push block 12 and the connecting rod 13, the first spring 14 is movably sleeved outside the connecting rod 13 after the rod is installed. One end of the spring 14 is movably inserted into the spring chamber of the active push block 12 and presses against the chamber wall, and the other end presses against the nail tail end of the connecting rod 13. When the connecting rod 13 continues to move, the active push block 12, which has slid completely, is restricted from sliding, so that the unlocked connecting rod 13 slides in the active push block 12, and the first spring 14 is compressed and undergoes elastic deformation. Through the transitional sliding of the connecting rod 13, after driving the outer glass curtain wall 3 to slide and unfold, it can also drive other mechanisms in a linkage manner. Furthermore, as described above, since the connection between the unlocking hole and the groove wall in the unlocking groove 18 is provided with an inclined sidewall, when the connecting rod 13 initially resets, the elastic deformation of the first spring 14 resets the connecting rod 13 within the active push block 12. At this time, the first spring 14 also provides elastic support, keeping the active push block 12 in a fully slidable state. When the connecting rod 13 resets and slides within the active push block 12, the hemispherical end of the positioning pin 16 follows the unlocking groove 18. The inclined sidewall of the unlocking hole slides back into the unlocking groove 18. After the hemispherical pin tail of the positioning pin 16 disengages from the unlocking hole in the unlocking groove 18, the positioning pin 16 is pushed again and slides out in the active push block 12, so that the pin head of the positioning pin 16 automatically re-engages with the connecting rod 13, and re-locks the connecting rod 13 and the active push block 12. When the connecting rod 13 continues to reset, the locking action of the positioning pin 16 causes the connecting rod 13 to drive the active push block 12 to reset and slide.

[0029] Meanwhile, in the above technical solutions, according to Figure 6 As shown, the nail head end of the connecting rod 13 is sleeved and fixedly connected with an end cap by bolts. The limiting assistance of the end cap prevents the connecting rod 13 from slipping off the active push block 12 when the connecting rod 13 is resetting and sliding.

[0030] Example 2: Based on Embodiment 1, please refer to the following: Figures 7-12 The technical solution shown is that the ventilation structure in existing curtain walls mostly uses filter plates to filter impurities mixed in the fresh air. However, the impurities are easy to accumulate on the filter plates after filtration, which is not easy to clean. Long-term accumulation can easily cause filter plate blockage and affect ventilation. To address the problem of inconvenient cleaning, an arc-shaped baffle 21 is set in the ventilation duct frame 20. When collecting fresh air, the fresh air is made to generate vortex motion, making it easier for the arc-shaped filter plate 22 to capture impurities. In addition, the impurities accumulated on the arc-shaped filter plate 22 can be scraped and cleaned by pulling the cleaning ball 29, eliminating the need for cleaning workers to climb the curtain wall for cleaning.

[0031] Specifically, in this technical solution, the energy-saving curtain wall ventilates the interior through the ventilation mechanism 19, according to... Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the driven push block 25 is mirrored about the vertical central axis of the shell frame 6. Each driven push block 25 corresponds to each drive component 7. Since the driven push block 25 has an integrated support leg facing the ventilation pipe frame 20, after the driven push block 25 is installed, it is movably locked in the shell cavity of the shell frame 6 along with the support leg. Through the square structure characteristics of the driven push block 25 itself and the limiting assistance of its support leg, the driven push block 25 is positioned in the shell cavity of the shell frame 6 in a movable state. It is restricted to linear sliding only. After the connecting rod 13 transitions and slides, it can also drive the ventilation mechanism 19 to work. When the connecting rod 13 continues to move and slides in the active push block 12, the nail head end of the connecting rod 13 is connected to the driven push block 25 by pressing, pushing the driven push block 25 to slide in the shell cavity of the shell frame 6. Since a third spring 26 is installed at the sliding connection between the driven push block 25 and the shell plate frame 6, after the third spring 26 is installed, one end of it is movably inserted into the spring compartment of the driven push block 25 and presses against the compartment wall, and the other end of it presses against the shell plate frame 6. After the driven push block 25 slides in the shell plate frame 6, the third spring 26 is compressed and undergoes elastic deformation. Since the upper driven push block 25 and the lower driven push block 25 share the same shaft, the upper end of the shaft is inserted into and fixedly connected to the support leg of the upper driven push block 25 with bolts, and the lower end of the shaft is inserted into and fixedly connected to the support leg of the lower driven push block 25 with bolts. Furthermore, since the end of the sealing plate 23 facing the driven push block 25 is the inward end, and the other end is the outward end, the lever portion 2301 is integrally structured and inclined at the inward end of the sealing plate 23, and its position at the inward end of the sealing plate 23 is... The push plate 2301 and the driven push block 25 are arranged at equal intervals. After the push plate 2301 is connected to the driven push block 25, the shaft on the driven push block 25 moves through the sliding groove on the push plate 2301. A bearing is installed at the connection between the shaft on the driven push block 25 and the push plate 2301, so that the shaft on the driven push block 25 forms a sliding structure on the push plate 2301. When the driven push block 25 is pushed and slids, the shaft on the driven push block 25 drives the shaft on it to slide synchronously. Through the sliding cooperation between the shaft on the driven push block 25 and the push plate 2301, the push plate 2301 is pushed to move. Since the ventilation mechanism 19 is vertically arranged between the outer glass curtain wall 3 and the inner glass curtain wall 2, it is mirrored about the vertical center axis of the outer glass curtain wall 3. The two ventilation mechanisms 19 correspond to the left and right vertical keels of the grid frame in the keel frame 1, and since the ventilation pipe frame 20 protrudes from the side of the vertical keel in the keel frame 1, it has an integrated assembly block. The assembly blocks are evenly spaced on the ventilation pipe frame 20. After the ventilation pipe frame 20 is installed, it fits and overlaps with the vertical keel of the keel frame 1, and the assembly blocks are snapped onto the vertical keel in the keel frame 1. The assembly blocks are fixedly connected to the vertical keel in the keel frame 1 by bolts. Since the front side of the ventilation duct frame 20 is open as an air inlet, which is used for outdoor air to enter the ventilation duct frame 20, the structure of the sealing plate 23 is adapted to the structure of the ventilation duct frame 20 and is set in an arc shape. Since the inner end of the sealing plate 23 is movably inserted with a shaft column, and a bearing is installed at the connection between the sealing plate 23 and the shaft column, after the sealing plate 23 is installed, its inner end is movably locked on one side of the air inlet slot in the ventilation duct frame 20, and the shaft column on its inner end is inserted and fixedly connected to one side of the air inlet slot by bolts, and its outer end is locked on the other side of the air inlet slot in the ventilation duct frame 20. When the push plate part 2301 is pushed, it drives the sealing plate 23 to move synchronously, so that the sealing plate 23 forms a flipping structure on the ventilation duct frame 20 with the assistance of the shaft column on it. Since torsion springs 24 are installed at equal intervals at the flip connection between the sealing plate 23 and the ventilation pipe rack 20, after the torsion springs 24 are installed, one end of the torsion springs 24 is movably inserted into the spring chamber of the sealing plate 23 and locked onto the chamber wall, and the other end of the torsion springs 24 is movably inserted into the spring chamber of the ventilation pipe rack 20 and locked onto the chamber wall, after the sealing plate 23 flips and unfolds on the ventilation pipe rack 20, the torsion springs 24 are compressed and undergo elastic deformation, and lose their sealing effect on the air inlet slot in the ventilation pipe rack 20, that is, the ventilation pipe rack 20 is in the open state. Because the ventilation duct frame 20 has an integrated structure with an arc-shaped baffle 21 inside the cavity, and the arc-shaped baffle 21 extends forward in an arc from the rear cavity wall of the ventilation duct frame 20, that is, the arc-shaped baffle 21 does not block the air inlet slot in the ventilation duct frame 20, and a gap is reserved between the two. Since the arc center of the arc-shaped baffle 21 is set eccentrically with the center of the ventilation duct frame 20, the cavity of the ventilation duct frame 20 is set into a vortex shape by the arc-shaped baffle 21. When the outdoor fresh air enters the cavity of the ventilation duct frame 20 through the air inlet slot in the ventilation duct frame 20, the arc-shaped baffle 21 guides and bends the airflow, causing the fresh air to rotate in the cavity of the ventilation duct frame 20, thereby forming a stable vortex structure. Because the ventilation duct frame 20 has an integrated air outlet on its rear side, the air outlet is used for airflow from the ventilation duct frame 20 to the room. Because the arc-shaped baffle 21 has through-holes at equal intervals, the arc-shaped baffle 21 divides the cavity of the ventilation duct frame 20 and the air outlets are used to connect the air outlets in the ventilation duct frame 20 to the cavity of the ventilation duct frame 20. Because the arc-shaped filter plate 22 is embedded and fixed to the arc-shaped baffle 21 with bolts, and it blocks the air outlets on the arc-shaped baffle 21, when fresh air enters the cavity of the ventilation duct frame 20, the arc-shaped baffle 21 creates a vortex. The fresh air flows through the arc-shaped filter plate 22 to filter impurities in the airflow, so that the clean fresh air enters the room through the air outlets on the arc-shaped baffle 21 and the air outlets in the ventilation duct frame 20. Based on the above, when the connecting rod 13 returns to its original position and slides, its nail head end and the driven push block 25 lose their opposing and pushing effect. The driven push block 25 returns to its original position and slides within the shell frame 6 by the elastic deformation of the third spring 26. After the driven push block 25 returns to its original position and slides, it drives the lever part 2301 to return to its original position and move synchronously. The sealing plate 23 returns to its original position and flips closed on the ventilation pipe frame 20 by the elastic deformation of the torsion spring 24. The sealing plate 23 then re-seals the air inlet slot in the ventilation pipe frame 20. That is, the ventilation pipe frame 20 is in a closed state, so that the ventilation mechanism 19 can be controllably adjusted to open or close.

[0032] Meanwhile, in the above technical solutions, according to Figure 7 and Figure 10 As shown, after the ventilation duct frame 20 is connected to the shell plate frame 6, the left and right ends of the upper shell plate frame 6 are respectively overlapped and fixed to the upper ends of the two ventilation duct frames 20 with bolts, and the left and right ends of the lower shell plate frame 6 are respectively overlapped and fixed to the lower ends of the two ventilation duct frames 20 with bolts. In addition, the left and right sides of the inner glass curtain wall 2 are respectively fixed to the rear side walls of the left and right ventilation duct frames 20 with bolts. The inner glass curtain wall 2 is fixedly installed on the keel frame 1 through the auxiliary connection of the shell plate frame 6 and the auxiliary connection of the ventilation duct frame 20.

[0033] Meanwhile, in the above technical solutions, according to Figure 8 As shown, the fresh air undergoes vortex motion within the cavity of the ventilation duct 20, causing suspended debris in the airflow to deflect towards the arc-shaped filter plate 22 due to centrifugal force. This makes it easier for the debris to contact the arc-shaped filter plate 22 and be captured by it. At the same time, it helps to distribute the airflow evenly, making the arc-shaped filter plate 22 uniformly loaded and improving the filtration efficiency.

[0034] Meanwhile, in the above technical solutions, according to Figure 8 , Figure 9 and Figure 11As shown, the end of the connecting plate 27 facing the sealing plate 23 is the outward end, and the other end is the inward end. Since the outward end of the connecting plate 27 is inserted and fixedly connected to the shaft column by bolts, after the connecting plate 27 and the sealing plate 23 are connected, the outward end of the connecting plate 27 is movably locked on the outward end of the sealing plate 23, and the shaft column moves through the outward end of the sealing plate 23. Furthermore, a bearing is installed at the connection between the shaft column and the sealing plate 23, so that the outward end of the connecting plate 27, with the assistance of the shaft column on it, forms a flipping structure on the outward end of the sealing plate 23. Since the upper and lower sides of the connecting plate 27 are rotatably connected to rollers, and the cross-sectional shape of the rollers is "I" shaped, and since the structural shape of the slide rail 28 is compatible with the structural shape of the "I" shaped rollers in the connecting plate 27, they are set up in a mirror image about the horizontal central axis of the connecting plate 27. After the upper and lower slide rails 28 are installed, they are respectively snapped together and fixed to the upper and lower sides of the outer glass curtain wall 3 by bolts. After the slide rail 28 is connected to the connecting plate 27, the rollers on the upper side of the connecting plate 27 are movably snapped in the upper slide rail 28, and the rollers on the lower side of the connecting plate 27 are movably snapped in the lower slide rail 28, so that the rollers on the connecting plate 27 form a sliding structure in the slide rail 28. Since the connecting plate 27 is installed and its inward end is connected to the outer glass curtain wall 3 in a fitted manner, and since the connecting plate 27 is used to cover the gap formed between the outer glass curtain wall 3 and the ventilation pipe frame 20 to prevent debris from entering between the outer glass curtain wall 3 and the inner glass curtain wall 2 and affecting the drive component 7, when the drive component 7 only drives the outer glass curtain wall 3 to slide and unfold without driving the ventilation mechanism 19 to work, the sliding and unfolding of the outer glass curtain wall 3 drives the connecting plate 27 to move synchronously, so that the inward end of the connecting plate 27 moves along the slide rail frame 28 on the outer glass curtain wall. The curtain wall 3 slides on the curtain wall 3, and the outward end of the connecting plate 27 flips on the sealing plate 23, so that the sealing plate 23 in the closed state does not affect the sliding and unfolding of the outer glass curtain wall 3. In addition, when the drive assembly 7 drives the ventilation mechanism 19 to operate, the sealing plate 23 flips and unfolds, and the outward end of the connecting plate 27 flips on the sealing plate 23, so that the inward end of the connecting plate 27 slides on the outer glass curtain wall 3 along the slide rail 28, and the inward end of the connecting plate 27 slides against the outer glass curtain wall 3, without affecting the flipping and unfolding of the sealing plate 23.

[0035] Specifically, in this technical solution, during the cleaning operation of the arc-shaped filter plate 22, according to... Figure 12As shown, the left and right ends of the cross bracing keel in the keel frame 1 are provided with through-hole cleaning round holes, and the left and right ends of the shell plate frame 6 are provided with through-hole cleaning round holes. After the shell plate frame 6 is installed, two of the cleaning round holes are respectively connected to the two cleaning round holes in the keel frame 1. The upper and lower ends of the ventilation pipe frame 20 are provided with through-hole cleaning round holes. After the ventilation pipe frame 20 is connected to the shell plate frame 6, the cleaning round holes in the ventilation pipe frame 20 are connected to the cleaning round holes in the shell plate frame 6. Because the arc-shaped filter plate 22 and the arc-shaped baffle 21 are concentrically arranged and have the same diameter, the centers of the cleaning holes in the ventilation duct frame 20, the shell plate frame 6, and the keel frame 1 are all on the same vertical central axis as the arc center of the arc-shaped filter plate 22, and their diameters are all the same as the diameter of the arc-shaped filter plate 22. Furthermore, because the specifications of the cleaning ball 29 are compatible with the specifications of the cleaning holes in the ventilation duct frame 20, the cleaning ball 29, when inserted into the ventilation duct frame 20, can fit snugly against the arc-shaped filter plate 22. A pull rope is fixed to the center of the cleaning ball 29. When using the cleaning ball 29, insert the pull rope into the cleaning hole in the uppermost keel frame 1, and move it sequentially through the cleaning holes in multiple ventilation duct frames 20, multiple shell plate frames 6, and multiple keel frames 1. Then, extend the pull rope from the cleaning hole in the lowermost keel frame 1. Pull the pull rope to move the cleaning ball 29 so that it fits against the arc-shaped filter plate 22 and moves within the ventilation duct frame 20. This scrapes and cleans the debris accumulated on the arc-shaped filter plate 22. The cleaned debris slides down the ventilation duct frame 20 and is discharged externally, allowing cleaning workers to avoid climbing the curtain wall and achieving the purpose of convenient cleaning.
