[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention, which provides a modular adjustable-angle prefabricated curtain wall. The modular adjustable-angle prefabricated curtain wall includes a base 1, a connecting shaft 2, a panel 3, a housing 4, a cylinder 5, a piston 6, a push rod 7, an adjusting rod 8, an expansion member 9, and a damping member 10. Energy-saving glass is fixed at the window of the panel 3, providing excellent heat insulation and light transmission performance, effectively reducing building energy consumption. Rapid installation is achieved by fixing the panel 3 to a crossbeam via the base 1. The adjustment rod 8 drives the piston 6 to move, precisely adjusting the tilt angle of the panel 3. Simultaneously, the expansion member 9 and the damping member 10 work together to provide adaptive buffering and reset functions for the panel 3 under external forces such as wind pressure, effectively solving the problem of rainwater infiltration and reduced curtain wall lifespan caused by the gaps in traditional rigid adjustment mechanisms. The combination of the energy-saving glass panel and the precision adjustment mechanism ensures the thermal performance of the building envelope and optimizes indoor lighting and shading effects through angle adjustment, further enhancing the building's energy efficiency.

[0030] Specifically, the base 1, fixed to the crossbeam, provides a stable installation foundation for the entire curtain wall unit. Connecting shafts 2 are installed at each of the four corners of the base 1. The ends of the connecting shafts 2 are rotatably connected to the panel 3, forming a multi-point support structure between the panel 3 and the base 1. This effectively disperses the wind load borne by the panel 3, improves the overall structural strength, and avoids stress concentration that could damage the energy-saving glass panel.

[0031] The housing 4, located at the top and bottom of the base 1, houses the core components for adjustment and buffering. The cylinder 5, fixed within the housing 4, has a piston 6 slidably connected inside. A push rod 7 is fixedly connected to one side of the piston 6, with its end rotatably connected to the panel 3. The piston 6 divides the interior of the cylinder 5 into two chambers. By controlling the hydraulic oil pressure in the two chambers, the piston 6 can be moved, thereby causing the panel 3 to rotate and adjust its angle. Energy-saving glass, typically with a low-emissivity coating or heat-insulating layer, is fixed to the window of the panel 3. During angle adjustment, it allows for optimized control of the solar radiation incident angle, adjusting the lighting and shading effects according to the solar radiation requirements of different seasons.

[0032] Adjusting rod 8, which is located on one side of cylinder 5 and threadedly connected to piston 6, Figure 4 and Figure 5 As can be seen, the adjusting rod 8 is composed of two cylindrical sections with different diameters. The larger diameter end is located on the outside of the cylinder 5, while the smaller diameter end is inserted into the cylinder 5 and threadedly connected to the piston 6. The position of the piston 6 is restricted by the contact between the larger end and the cylinder 5, thereby enabling manual adjustment of the extension of the push rod 7 and the elevation angle of the control panel 3.

[0033] Because the diameter of push rod 7 is larger than that of adjusting rod 8, the pressure area of ​​piston 6 facing push rod 7 is smaller than that facing away from push rod 7. Under the same hydraulic pressure, the thrust on the side of piston 6 facing away from push rod 7 is greater. Under the action of pressure difference, piston 6 and push rod 7 actively provide support for panel 3, ensuring the support stability of panel 3. Expansion member 9 is located at the bottom of cylinder 5 and communicates with both sides of cylinder 5, allowing hydraulic oil on both sides of piston 6 to circulate within expansion member 9. Damping member 10 is located between expansion member 9 and cylinder 5, used to provide variable buffer damping when piston 6 moves rapidly.

[0034] In the initial state, the expansion member 9 is connected to both sides of the cylinder 5. Under the same pressure, the thrust on the left side of the piston 6 is greater than the thrust on the right side of the piston 6, causing the piston 6 to automatically move to the right. This makes the threaded groove of the piston 6 fit tightly with the threaded surface of the adjusting rod 8, eliminating the micro-vibration that may be caused by the gap of traditional mechanical threads, improving the system rigidity, ensuring the stability of the curtain wall in long-term use, and also ensuring that the energy-saving glass panel is always in the preset optimal angle position to maintain its energy-saving effect.

[0035] The fixing method of the base 1 and the crossbeam, the hydraulic oil circuit sealing technology, and the preparation process of the energy-saving glass are all existing technologies. The working principle of this part is also an existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0036] Example 2, refer to Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the expansion component 9 includes a connecting frame 91, an elastic bladder 92, and a conduit 93. The connecting frame 91 is fixedly connected to the housing 4, providing stable mounting support for the elastic bladder 92. The elastic bladder 92 is fixedly connected inside the connecting frame 91 and has elastic contraction capability, expanding to store energy when hydraulic oil flows in and contracting to release energy when hydraulic oil flows out. The conduit 93 is fixed to both sides of the top of the elastic bladder 92 and communicates with both sides of the cylinder 5 respectively, allowing hydraulic oil to circulate between the two chambers of the cylinder 5 and the elastic bladder 92, forming a closed hydraulic circuit.

[0038] The elastic bladder 92 can also store expanded hydraulic oil in high-temperature environments to prevent excessive system pressure.

[0039] A rotating shaft 11 is rotatably connected to the side of the connecting frame 91 near the panel 3. A rotating ring 13 is connected to the outer wall of the rotating shaft 11 via a transmission component 12. The rotating ring 13 is coaxially mounted on the push rod 7 and rotatably connected to the housing 4. A brush 14 for cleaning the push rod 7 is provided on the inner wall of the rotating ring 13. The end of the rotating shaft 11 extends into the elastic bladder 92 and is fixedly connected to a turbine 15.

[0040] When hydraulic oil flows at high speed between the expander 9 and the cylinder 5, the flowing hydraulic oil impacts the turbine 15, driving the turbine 15 to rotate. The turbine 15 drives the rotating shaft 11 to rotate, and the rotating shaft 11 transmits power to the rotating ring 13 through the transmission component 12, causing the rotating ring 13 to drive the brush 14 to rotate around the axis of the push rod 7. During rotation, the brush 14 continuously cleans the surface of the push rod 7 exposed on the outside of the cylinder 5, effectively removing dust and impurities attached to the push rod 7. This prevents dust from entering the cylinder 5 with the extension and retraction of the push rod 7, preventing seal failure or jamming due to impurities, and ensuring the long-term reliability of the adjustment mechanism. The clean surface of the push rod 7 also means that the connected panel can always maintain precise adjustment accuracy, avoiding adjustment errors caused by the accumulation of impurities from affecting the shading angle of the panel 3, thereby maintaining the optimal optical performance of the energy-saving glass.

[0041] The aforementioned transmission component 12 can be a toothed belt or chain drive.

[0042] Example 3, referring to Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, the damping component 10 includes a sleeve 101, a damping rod 102, and a connecting plate 103. The sleeve 101 is connected to two conduits 93, allowing hydraulic oil to pass through the inside of the sleeve 101 when flowing through the conduits 93. The damping rod 102 is slidably connected inside the sleeve 101 and is used to adjust the flow cross-section of the hydraulic oil. The connecting plate 103 is located on the side of the sleeve 101 away from the panel 3, and its upper and lower sides are connected to the adjusting rod 8 and the damping rod 102, respectively, so that the position of the damping rod 102 can change synchronously with the movement of the adjusting rod 8.

[0044] Two damping grooves 16 are spaced apart on the outer wall of the damping rod 102 corresponding to the position of the conduit 93. The depth of one damping groove 16 closer to the panel 3 is less than the depth of the other damping groove 16. This design of damping grooves 16 with different depths causes the resistance of hydraulic oil flowing through the damping grooves 16 to change with the position of the damping rod 102.

[0045] When the prefabricated curtain wall is subjected to wind pressure impact, panel 3 will compress the push rods 7 on both the upper and lower sides to retract, pushing piston 6 to move to the left within cylinder 5. During the rapid leftward movement of piston 6, the hydraulic oil in the left-side chamber of piston 6 is compressed, flowing into the elastic bladder 92 through the left-side conduit 93, and then into the right-side chamber of piston 6 through the right-side conduit 93. Since the leftward movement of piston 6 will cause the adjusting rod 8 to move to the left as well, the adjusting rod 8 pulls the damping rod 102 to move synchronously to the left within sleeve 101 via connecting plate 103. At this time, the shallower damping groove 16 coincides with the corresponding conduit 93. The shallower depth of the damping groove 16 reduces the flow cross-section of the hydraulic oil, thereby generating greater flow resistance and rapidly increasing the buffer damping force. This buffering method, which first rapidly releases pressure and then gradually increases the support strength, allows panel 3 to have some displacement to absorb energy in the early stages of wind pressure impact, and provides sufficient support force in the later stages of impact to prevent excessive deformation of panel 3. This effectively improves the wind pressure resistance of the prefabricated curtain wall and also protects the energy-saving glass from the risk of breakage caused by severe impact.

[0046] When the wind pressure decreases, the piston 6 is pushed back to its original position by the elastic contraction force of the elastic bladder 92 and the hydraulic oil pressure. This allows the panel 3 to automatically return to the preset angle after the wind pressure disappears, realizing the adaptive reset function of the curtain wall under external force. This reset function ensures that the energy-saving glass always maintains the preset optimal lighting and shading angle, enabling the building to obtain optimized natural light utilization efficiency in different seasons and at different times, reducing the energy consumption of artificial lighting and air conditioning.

[0047] Example 4, refer to Figure 1 and Figure 2 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0048] Specifically, each of the four corners of the base 1 has a circular groove 17, and the connecting shaft 2 is slidably connected in the circular groove 17, so that the connecting shaft 2 can extend and retract along the axial direction of the circular groove 17. One end of the connecting shaft 2 extending out of the circular groove 17 is rotatably connected to the panel 3, so that the connecting shaft 2 can adaptively adjust the angle when the panel 3 is flipped and adjusted, maintaining a reliable connection with the panel 3.

[0049] One of the housings 4 is rotatably connected to the base 1, and the other housing 4 is fixedly connected to the base 1. A groove 18 is provided on the side wall of the panel 3 on the same side as the rotatably connected housing 4, and a slider 19 that is rotatably connected to the corresponding connecting shaft 2 is slidably connected in the groove 18.

[0050] Since the crossbeam cannot deform after installation, the base 1 fixed to the crossbeam also cannot deform. Therefore, one of the housings 4 is rotatably connected to the base 1. This allows the housing 4 to adaptively adjust its angle when the panel 3 is flipped and adjusted, avoiding structural interference caused by the fixed connection of the two housings 4 during panel 3 adjustment. Simultaneously, a groove 18 and a slider 19 are provided on the same side of the panel 3 corresponding to the rotatably connected housing 4. When the push rod 7 in the fixedly connected housing 4 extends and pushes the panel 3 to flip, the rotatably connected housing 4 adjusts its angle accordingly. The slider 19 slides within the groove 18 to compensate for changes in the relative position between the connecting shaft 2 and the panel 3, ensuring a stable connection between the panel 3 and the connecting shaft 2 at the four corners of the base 1 at any adjustment angle. When the push rods 7 in both housings 4 extend synchronously to the same length, the horizontal position of the panel 3 can also be adjusted, giving the prefabricated curtain wall more adjustment freedom, facilitating precise alignment during on-site installation, and providing more flexible adjustment space for the installation of energy-saving glass panels. This ensures that multiple glass panels are spliced ​​flat and well-sealed, avoiding thermal bridging caused by installation errors.

[0051] Example 5, refer to Figure 4 This is the fifth embodiment of the present invention, which is based on the previous four embodiments.

[0052] Specifically, a sealing ring 20 is fixedly connected to the side of the cylinder body 5 away from the panel 3, and an adjusting rod 8 is slidably disposed inside the sealing ring 20. The sealing ring 20 can effectively prevent hydraulic oil from leaking from the gap between the adjusting rod 8 and the cylinder body 5, ensuring the sealing performance of the hydraulic system.

[0053] A receiving groove 21 is provided on the side of the cylinder body 5 away from the panel 3. A spring 22 for supporting the piston 6 is fixedly connected in the receiving groove 21. The spring 22 is coaxially arranged on the outside of the adjusting rod 8. The spring 22 always applies a thrust to the piston 6 in the direction of the panel 3. In the initial state, it works together with the hydraulic pressure to keep the threaded groove of the piston 6 in close contact with the threaded surface of the adjusting rod 8, eliminating thread clearance. After the panel 3 is subjected to wind pressure impact, the spring 22 can also provide an auxiliary thrust for the piston 6 to reset, improving the reset response speed.

[0054] In practical engineering applications, the loads borne by curtain wall units include self-weight dead load, wind load, and seismic action, which need to be calculated in combination according to standards such as the "Code for Design of Building Structures" (GB50009) and the "Technical Code for Glass Curtain Wall Engineering" (JGJ102). Those skilled in the art can determine the maximum design load (including safety factor) at a single connection node based on parameters such as the specific curtain wall unit dimensions, the basic wind pressure of the region, the height variation coefficient, and the gust coefficient, thereby determining the maximum thrust required by the hydraulic system.

[0055] Based on this maximum thrust, and according to the conventional formula in hydraulic transmission design manuals (P=F / A, where A is the effective working area of ​​the piston), the cylinder diameter and piston rod diameter can be reasonably selected, ensuring that the system working pressure is within the rated working range of commonly used hydraulic components (such as seals and pipelines) (typically 1-10 MPa). The hydraulic system of this invention has sufficient pressure adjustment margin; the initial piston position can be changed by adjusting the thread feed of the adjusting rod, thereby adapting to the support force requirements under different working conditions. Simultaneously, the structural parameters of the expansion and damping components (such as the volume of the elastic bladder, the depth and number of damping grooves) can also be adapted and adjusted according to the maximum design load. These adjustment methods are all conventional technologies in the hydraulic field.

[0056] Therefore, specific numerical examples are not required in the specification. Those skilled in the art, after reading the overall technical solution of this invention and combining it with common knowledge and regulatory requirements, are fully capable of designing system parameters that meet the needs of actual engineering projects, and are confident that it can achieve the claimed beneficial effects such as "adaptive buffering and reset" and "elimination of activity gaps."

[0057] In use, the base 1 is fixed to the crossbeam, thus completing the rapid installation of the prefabricated curtain wall. When it is necessary to adjust the elevation angle of the curtain wall, the adjusting rod 8 is rotated using a tool. The adjusting rod 8, through its threaded engagement with the piston 6, pushes the piston 6 to move to the right within the cylinder 5. The hydraulic oil in the right chamber of the piston 6 enters the elastic bladder 92 through the right conduit 93, and then flows back to the left chamber of the piston 6 through the left conduit 93, forming a circulation of hydraulic oil. This causes the push rod 7 to extend and push the panel 3 to flip outward, achieving precise adjustment of the curtain wall angle. By adjusting the angle of the panel 3, the angle at which the energy-saving glass receives solar radiation can be changed: in summer, adjusting the panel 3 to a larger tilt angle can effectively block direct sunlight from entering the room, reducing the air conditioning load; in winter, adjusting the panel 3 to a smaller tilt angle allows sunlight to pass through the glass at a better angle, increasing the passive solar heating effect and achieving active energy-saving adjustment of the curtain wall.

[0058] When the prefabricated curtain wall is subjected to wind pressure, the panel 3, under pressure, pushes the push rod 7 to retract, and the piston 6 moves to the left within the cylinder 5. The hydraulic oil in the left chamber of piston 6 is compressed, flows through the left conduit 93 into the elastic bladder 92, and then through the right conduit 93 into the right chamber of piston 6. During this process, the leftward movement of piston 6 causes the adjusting rod 8 to move synchronously to the left. The adjusting rod 8, through the connecting plate 103, pulls the damping rod 102 to the left, causing the shallower damping groove 16 to overlap with the conduit 93. This reduces the hydraulic oil flow cross-section and rapidly increases the damping force, effectively slowing down the movement of panel 3 and absorbing impact energy. After the wind pressure decreases, under the combined action of the elastic contraction force of the elastic bladder 92, the thrust of the spring 22, and the hydraulic pressure, piston 6 is pushed back to the right, causing the push rod 7 to extend again, and panel 3 automatically returns to the preset angle. This buffering and reset mechanism effectively protects the energy-saving glass panel from fatigue damage caused by wind pressure fluctuations, extending its service life.

[0059] As hydraulic oil flows at high speed through the expander 9, it impacts the turbine 15, causing it to rotate. The turbine 15 drives the rotating shaft 11 to rotate, which in turn drives the rotating ring 13 and brush 14 to rotate around the axis of the push rod 7 via the transmission component 12. The brush 14 continuously cleans the dust and impurities adhering to the surface of the part of the push rod 7 that extends out of the cylinder 5, preventing impurities from entering the cylinder 5 as the push rod 7 extends and retracts, thus ensuring the long-term sealing performance and operational reliability of the adjustment mechanism. The clean push rod 7 ensures the continuous stability of the adjustment accuracy, enabling the energy-saving glass panel to always respond precisely to adjustment commands and maintain its preset energy-saving operating state.

[0060] Because one of the two housings 4 on the base 1 is fixedly connected and the other is rotatably connected, and the panel 3 is provided with a groove 18 and a slider 19 on the same side as the rotatably connected housing 4, when the push rod 7 in the fixedly connected housing 4 extends to push the panel 3 to flip, the rotatably connected housing 4 will adaptively adjust its angle, and the slider 19 will slide in the groove 18 to compensate for position changes, ensuring that the panel 3 maintains a stable connection with the connecting shafts 2 at the four corners of the base 1 under any adjusted angle, forming a reliable multi-point support structure, which effectively improves the overall structural strength and wind pressure resistance of the prefabricated curtain wall. This multi-point support combined with the energy-saving glass panel design not only meets the mechanical performance requirements of the building envelope structure, but also achieves active optimization of building energy consumption through precise angle adjustment, so that the curtain wall system can ensure safety while also having good energy-saving benefits and indoor environmental comfort.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
