[0036] Window opening method and working principle:

[0037] The window opening device of the double-glazed curtain wall described in Embodiment 1 is divided into an outer upper window sash, an outer lower window sash, an inner upper window sash, and an inner lower window sash according to the different positions of the window sash on the glass curtain wall. By setting an opening assembly between the window sash and the window frame, the driving device in the opening assembly drives the hinge to extend or retract, thereby driving the window sash to rotate along its rotation axis to realize the rotation opening or closing of the window sash. In this case, the driving device remains stationary during the rotation opening or closing process of the window sash, which improves the reliability of the opening device and has a simple structure.

[0038] It should be noted that three opening and closing modes are provided during the rotation of the outer upper window sash, outer lower window sash, inner upper window sash, and inner lower window sash. The first mode is 0° mode, in which the window sash is tightly fitted to the window frame and the curtain wall is fully closed. The second mode is 70° opening mode, in which the window sash is fully open. The third mode is free mode, which allows adjustment within the range of 0° to 70° as needed.

[0039] It should also be noted that in summer, the chimney effect of the double-glazed curtain wall allows air to flow upwards through the cavity by adjusting the opening angles of the outer upper and lower windows, as well as the inner upper and lower windows, thus convecting and refreshing the indoor air. Specifically, the cavity between the outer and inner glass panels in the double-glazed curtain wall serves as a ventilation cavity. Adjusting the window angles regulates the airflow and exchange intensity within the cavity, improving indoor air quality and reducing indoor temperature. In winter, the outer upper and lower windows, along with the inner upper and lower windows, effectively close the curtain wall as an insulation layer. The windows can be opened as needed for ventilation, reducing the reliance on the air conditioning system.

[0040] In this embodiment 1, an electric servo motor is used as the driving device. Each electric servo motor only requires two cables, which effectively reduces the arrangement of wiring inside the curtain wall cavity, reduces the risk of failure, lowers costs, and increases the reliability of the control device. The electric servo motor cables are connected to the power control box on the same floor through a preset channel and connected to the DDC controller, thereby realizing the control of the outer upper window sash, outer lower window sash, inner upper window sash, and inner lower window sash on the same floor, thus realizing diverse control methods and strategy combinations.

[0041] In this embodiment 1, the first, second, third, and fourth window opening components each include a pneumatic booster rod 9. One end of the pneumatic booster rod 9 is connected to a preset part of the outer upper window frame, outer lower window frame, inner upper window frame, or inner lower window frame, and the other end of the pneumatic booster rod 9 is connected to the side wall of the outer upper window sash 10, outer lower window sash 11, inner upper window sash 12, or inner lower window sash 13. By setting the pneumatic booster rod 9 between the window frame and the window sash, the pneumatic booster rod 9 is used as an auxiliary in the process of controlling the opening of the window sash by the electric servo motor. This ensures that the window sash and the curtain wall body are kept in close, accurate, and reliable control, and has high sealing performance and structural safety. Under the dual control of the electric servo motor and the pneumatic booster rod 9, the installation and performance requirements for high-rise curtain walls can be met.

[0042] In this embodiment 1, a sealing strip is provided between the window sash and the preset window frame; wherein, the sealing strip is provided on the edge of the window sash and located on the contact surface between the window sash and the preset window frame; specifically, sealing strips are provided on the inner edge of the outer upper window sash 10, the inner edge of the outer lower window sash 11, the outer edge of the inner upper window sash 12, and the outer edge of the inner lower window sash 13; by providing sealing strips on the edges of the window sash and at the contact surface with the preset window frame, the airtightness of the curtain wall is ensured; preferably, the sealing strip is made of a material with weather resistance, wind pressure resistance, and good sealing performance to ensure stability and airtightness during long-term use.

[0043] Example 2

[0044] This embodiment 2 is basically the same in structure and principle as embodiment 1 above, except that:

[0045] In this embodiment 2, an environmental sensing device and a remote control device are also included. The environmental sensing device is installed at a preset location inside or outside the building, and its output is connected to the input of the DDC controller. The environmental sensing device is used to collect preset environmental information inside or outside the building. Preferably, the environmental sensing device is a humidity sensor, a temperature sensor, or a wind speed sensor. The remote control device is connected to the input of the DDC controller and is used to send a window opening command to the DDC controller. The remote control device and the DDC controller are connected via a wireless network, and the remote control device is a remote online control platform or a mobile terminal.

[0046] It should be noted that in this embodiment 2, after the DDC controller receives the preset environmental information of the building's indoor or outdoor environment transmitted by the environmental sensing device, it compares the preset environmental information of the building's indoor or outdoor environment with the preset information threshold, and outputs and sends a start command to the first drive device 1, the second drive device 3, the third drive device 5 and the fourth drive device 7 according to the comparison result, so as to trigger the corresponding drive device to start or stop running.

[0047] Working principle:

[0048] The window opening device for the double-glazed curtain wall described in Embodiment 2 operates as follows:

[0049] Based on preset environmental information collected by the environmental sensing device from the building's indoor or outdoor environment, the DDC controller outputs a start command to the first drive device 1, the second drive device 3, the third drive device 5, and the fourth drive device 7. For example, when the indoor temperature is too high or the humidity is too high, the DDC controller outputs a start command to control the electric servo motor to start running, thereby opening the window sash through the hinge for ventilation. When the outdoor temperature is too low or the wind speed is too high, the DDC controller outputs a start command to control the electric servo motor to start running, thereby closing the window sash through the hinge. Furthermore, the user sends a window opening command to the DDC controller through a mobile device or a remote online control platform, thereby using the DDC controller to control the drive devices to open or close, achieving the purpose of remote window opening.

[0050] The window opening device for the double-glazed curtain wall described in this utility model employs an electric servo motor and an electric chain-type window opener, fixed in conjunction with a pneumatic booster rod. This significantly improves the stability of the curtain wall control and its reliability under different weather conditions, as well as the opening accuracy and performance under extreme weather conditions. A DDC controller sends opening and closing commands to the drive device to control its opening and closing, enabling group control of the double-glazed curtain wall's windows. This improves opening efficiency, facilitates indoor ventilation and building energy conservation, and reduces building energy consumption. Simultaneously, each group of window sashes can be freely controlled to achieve a preset opening angle, meeting diverse usage needs. Furthermore, it can be linked with the fire protection system in emergency situations for fire smoke extraction and routine equipment cleaning and maintenance. This utility model has a simple structure and reasonable design, making it feasible for practical projects and fully leveraging the ventilation and energy-saving advantages of double-glazed curtain walls.

[0051] The above embodiments are merely one of the implementation methods to achieve the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
