[0042] Example: When in use, first pre-set multiple fixings 27 inside the longitudinal beams 1 and transverse beams 2 that constitute the building's exterior wall, and fasten the longitudinal positioning columns 3 and transverse positioning columns 4 to the longitudinal beams 1 and transverse beams 2 respectively through the fixing holes 13 on their surfaces that correspond to the limiting holes 28 on the surfaces of the fixings 27 under the action of fastening bolts. Adjacent longitudinal positioning columns 3 and transverse positioning columns 4 are connected to each other through the longitudinal plug-in portion 30 and the longitudinal plug-in groove 33, and two adjacent transverse positioning columns 4 are connected to each other through the transverse plug-in portion 31 and the transverse plug-in groove 34. Figure 8As shown, the connection between the two longitudinal positioning columns 3 and the two transverse positioning columns 4 is locked by the locking mechanism 14, and the longitudinal plug-in portion 30 at any end of the two longitudinal positioning columns 3 is inserted into the longitudinal plug-in groove 33 of one of the transverse positioning columns 4, and the transverse plug-in portion 31 of the other transverse positioning column 4 is inserted into the transverse plug-in groove 34 which is perpendicular to the longitudinal plug-in groove 33, ensuring that the reserved holes 36 provided on the surfaces of the longitudinal plug-in portion 30 and the transverse plug-in portion 31 correspond to the locking holes 35 in the locking groove 22 on the surface of the transverse positioning column 4, and then the locking disk 23 is connected to the locking groove 22 through the locking pin 24 cooperating with the reserved hole 36 and the locking hole 35 and the locking nut 26 cooperating with the connecting hole, thereby fixing the two longitudinal positioning columns 3 and the two transverse positioning columns 4 connected to each other. During installation, first install the longitudinal positioning column 3 and the transverse positioning column 4 at one diagonal point of the regulating window, then install the regulating window or curtain panel 7, and finally install the longitudinal positioning column 3 and the transverse positioning column 4 at the other diagonal point opposite to the previous diagonal point. Repeat the above steps to complete the installation of the entire curtain wall.

[0043] When the adjustable window is in use, the first bevel gear 15 at the drive end of the drive motor cooperates with the second bevel gear 16 to drive the transmission rod 17, which drives the adjustable blade 11 to rotate. When the first bevel gear 15 rotates clockwise, the second bevel gear 16 rotates counterclockwise, driving the adjustable blade 11 to open, up to 90 degrees. To close, the first bevel gear 15 rotates counterclockwise. During the rotation of the second bevel gear 16, the piezoelectric block 19 rotates. The multiple piezoelectric protrusions 20 on the outer surface of the piezoelectric block 19 compress the piezoelectric ceramic plate 21, thereby generating electrical energy. The generated electrical energy is sequentially converted and stored in a battery through the functions of a full-bridge rectifier, a filter capacitor, a DC-DC converter, a supercapacitor, and a charge management chip. The battery can reverse power the drive motor. The number of batteries can be selected according to the size of the entire curtain wall. For example, the piezoelectric mechanism in the drive compartment 12 within a row or column of adjustable windows can be connected to the same battery or multiple batteries. At the same time, the curtain panels 7, panel 8, and regulating blades 11 are all made of transparent perovskite photovoltaic glass, which is also capable of self-generating electricity. The transparent perovskite photovoltaic glass used as the curtain panels 7, panel 8, and regulating blades 11 has a light transmittance of 60% and a power generation efficiency of 18%. It is used to drive its own motor. The excess electricity generated by the battery can also be connected to the building power system for lighting at night or in low light conditions. When the curtain panels 7, panel 8, and regulating blades 11 are connected to the battery, they pass through the anti-reverse diode and photovoltaic controller in sequence, thereby realizing the battery's function of collecting the electricity generated by the curtain panels 7, panel 8, and regulating blades 11.
