Smoke discharge and explosion venting window

Abstract

The invention discloses a smoke discharge and explosion venting window. The smoke discharge and explosion venting window is characterized by comprising a chassis assembly, a window frame, a casement, an explosion venting sash, an explosion venting window, an explosion venting device, an execution mechanism, a drive support assembly, a chain assembly and a control system, wherein the chassis assembly is installed on a wall body, the window frame is fixed on the chassis assembly, the casement is of a hollow frame structure and fixed on the window frame through a first hinge, and the explosion venting sash is located at the outer side of the casement and fixed on the casement through a second hinge; the explosion venting device is installed between the casement and the explosion venting sash; the drive support assembly is used for supporting the execution mechanism, and the push rod of the execution mechanism is fixed with the casement through a hinge; the both ends of the chain assembly are fixedly connected with the explosion venting window and the window frame respectively to limit the opening angles of the explosion venting window and the casement; the control system is used for controlling the action of the execution mechanism according to a smoke monitoring condition. The smoke discharge and explosion venting window disclosed by the invention realizes the functions of smoke discharge and explosion venting simultaneously, and is simple in structure, convenient to implement, simple in construction, and capable of greatly reducing construction cost.

Description

technical field [0001] The invention relates to a smoke exhaust and explosion relief window, which belongs to the technical field of building components. Background technique [0002] The function of the ordinary smoke exhaust window is that when the smoke signal is detected, the control system will give the smoke window control box a window opening signal, and the control box will control the window actuator to open the window and discharge the toxic smoke to the outside to ensure the safety of people inside the building. . [0003] The function of the ordinary explosion relief window is to open the window through the explosion relief device when the pressure at the installation position of the window meets the explosion relief pressure, so as to achieve the process of explosion relief and pressure relief, mainly passive pressure relief. [0004] However, when there are flammable and explosive items in some buildings, or some buildings need automatic smoke exhaust windows ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the existing smoke exhaust windows and explosion venting windows all have a single function of smoke exhaust or explosion venting. When some buildings need both smoke exhaust and explosion venting, separate Install smoke exhaust windows and explosion vent windows, resulting in troublesome construction and high cost
