AI Technical Summary
Due to design restrictions, the glass curtain walls of large public buildings cannot be opened to open sufficient smoke exhaust ventilation windows on the glass body, resulting in the need to increase mechanical smoke exhaust systems, increase building floor height and fire-fighting equipment costs.
An emergency smoke exhaust window for curtain wall is designed. By setting the curtain wall panel and the fixing frame into an upper structure, and a strip fan is fixed on the upper part of the front end of the curtain wall panel, the flue gas is discharged using the principle of hinge connection and pressure difference.
In the case of a fire emergency, the curtain wall panels are unfolded by their own weight, and the fan is used to accelerate the flue gas discharge, achieving effective flue gas removal, saving curtain wall installation costs, and facilitating maintenance.

[0011] Preferably, the window lock is located above and not in contact with the two strip fans.
[0012] Preferably, the two strip fans are not in contact with the fixing frame.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. In the utility model, by setting the curtain wall panel and the fixed frame into an upward opening structure, and the two hinges for connecting the curtain wall panel and the fixed frame do not have a damping effect, when the device is used, when a fire emergency occurs in the building, the curtain wall panel can be released through the window lock, and the curtain wall panel can be automatically unfolded outward by its own weight, and the indoor smoke can be discharged by the principle of different indoor and outdoor pressures. The smoke exhaust window can actively exhaust the smoke, which can save the cost of curtain wall installation and is more convenient for subsequent maintenance;
[0015] 2. In the utility model, two strip fans are fixedly installed on the upper front end of the curtain wall panel. When an emergency occurs indoors and the curtain wall panel is opened, the two strip fans can blow air upwards, so that the indoor smoke can flow outwards faster, thereby achieving a better smoke exhaust effect.

The two hinges 12 are respectively located inside the two storage grooves 11. The two connecting columns 33 are respectively movably connected to the two movable holes 13. The window lock 31 is located at the upper part between the two strip fans 32 and does not contact them. The two strip fans 32 do not contact the fixed frame 1. By fixing two strip fans 32 on the upper front end of the curtain wall panel 3, when an emergency occurs indoors and the curtain wall panel 3 is opened, the two strip fans 32 can blow air upwards, so that the indoor smoke can be accelerated to flow outward, and the smoke exhaust effect can be better achieved.
[0028] It should be noted that the utility model is an emergency smoke exhaust window for curtain walls. The curtain wall panel 3 and the fixed frame 1 are set to an upward opening structure, and the two hinges 12 used to connect the curtain wall panel 3 and the fixed frame 1 do not have a damping effect. When the device is in use, when a fire emergency occurs in the building, the curtain wall panel 3 can be released through the window lock 31, and the curtain wall panel 3 can unfold outward by its own weight, and discharge the indoor smoke by the principle of different indoor and outdoor pressures. The smoke exhaust window itself actively exhausts smoke, which can save the cost of curtain wall installation and is more convenient for subsequent maintenance. Two strip fans 32 are fixedly installed on the upper front end of the curtain wall panel 3. When an emergency occurs indoors and the curtain wall panel 3 is opened, the two strip fans 32 can blow air upwards, so that the indoor smoke can flow outwards faster, and the smoke exhaust effect can be better achieved.
