Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to a foldable and lifting large electric smoke barrier controlled by an integrated circuit. Background Art

[0002] Smoke barrier walls are architectural facilities installed in public places such as shopping malls, theaters, and garages for fire prevention. They are barriers that can block the horizontal flow of smoke and hot gases in the event of a fire, thereby preventing the spread of toxic smoke to other areas. They can effectively control the toxic smoke within the smoke-proof partition and discharge the toxic smoke from the fire area through the smoke exhaust pipe, so that people can be evacuated quickly and firefighters can enter in time, protecting people's lives and property and buying precious time for firefighting.

[0003] However, in practice, various integrated atriums and corridors have increasingly complex architectural shapes and higher requirements for special-shaped smoke barriers. The installation space is required to be small enough, and the length is getting longer and longer, with a span of over 100 meters. The requirements for product synchronization are getting higher and higher. If the synchronous lifting of multiple electric lifting devices cannot be solved, it will have a significant impact on the safety of the products. The existing smoke barriers are mostly one-machine-one-control mode, which is only suitable for straight smoke barriers in small spaces. Through parallel connection, one-control-two can be achieved, which is suitable for the control of larger spaces, but the stability and reliability are not good; each motor is equipped with a fire signal, which not only increases the unreliability, but also greatly increases the cost of other supporting equipment, low efficiency, and increases the capacity of the fire host and the cost of a large amount of wiring.

[0004] Furthermore, medium and large length smoke barrier walls adopt overlapping technology. According to industry requirements, the overlapping length is not less than ten centimeters, the gap of the smoke barrier wall is small, and the smoke leakage is not more than 25 cubic meters per hour. In addition, due to weight reasons, the smoke barrier curtain is 0.5mm, so scratches often occur during operation, especially during asynchronous operation, scratches and jams often occur, and the smoke barrier effect cannot be quickly and reliably achieved. Therefore, there is an urgent need for a large-scale special-shaped spliced ​​smoke barrier wall, or several independent smoke barrier walls in adjacent areas, which can be quickly raised or lowered synchronously after receiving instructions to achieve a quick smoke barrier effect.

[0022] The large folding fire curtain device 6 includes a large folding fire curtain 61, a fire curtain mounting plate 15 connected to the top of the large folding fire curtain 61, a counterweight base 63 connected to the bottom of the large folding fire curtain 61, a spring positioner 64 elastically connected to the bottom of the counterweight base 63, and a plurality of meniscus positioners 62 fixedly mounted on both sides of the top of the counterweight base 63, wherein the plurality of meniscus positioners 62 are evenly arranged on both sides of the front and back sides of the large folding fire curtain 61 in a folded state, and extend to both sides of the counterweight base 63, such as Figure 2 shown.
