Description

Technical Field

[0001] The utility model belongs to the field of smoke barrier vertical walls, in particular to a self-driven electric smoke barrier vertical wall. Background Art

[0002] The smoke barrier wall is made of non-combustible material and is a fixed or movable smoke barrier facility that hangs down from the ceiling by no less than 500mm.

[0003] Movable smoke barrier refers to a smoke barrier that automatically droops due to temperature, smoke or other control equipment during a fire.

[0004] Smoke barrier walls are mainly used in high-rise or super high-rise shopping malls, office buildings, warehouses and other places. They can effectively block the horizontal flow of smoke under the building ceiling, so as to improve the smoke exhaust effect within the smoke-proof partition and play a certain role in protecting the safety of life and property.

[0005] The existing patent authorization announcement number is CN213159066U, and the patent name is a utility model patent for an electric smoke barrier vertical wall. It records that it includes a crossbeam set on the roof, and a mounting groove is opened on the end face of the crossbeam away from the roof. A rotating shaft is rotatably connected between the two opposite groove walls of the mounting groove. A smoke barrier is connected to the outer edge of the rotating shaft through a connecting component. An electromagnet is provided on the top wall of the mounting groove, and an iron bar is provided on the smoke barrier. The iron bar is tightly adsorbed on the electromagnet. A smoke sensor is also provided on the crossbeam; when the smoke sensor is triggered, the electromagnet is powered off and demagnetized. The technical effect of this application is that the smoke barrier can be horizontally stored on the crossbeam when not in use, reducing the possibility that the normal airflow in the room is blocked by the smoke barrier, thereby improving the indoor ventilation effect.

[0006] When the above-mentioned device is used, it mainly relies on the smoke shield to block the smoke. When the size of the smoke shield is small, it cannot separate the channel. When the size of the smoke shield is large, part of the smoke shield will be in the air during daily use, affecting the ventilation effect, and it is not beautiful and has a poor use effect.

[0007] In summary, the existing irrigation controller installation structures have certain drawbacks when used and do not meet people's usage requirements. For this reason, we propose a self-driven electric smoke barrier vertical wall. Summary of the invention
