Fire-fighting smoke exhaust port opened through electromagnetism

Abstract

The invention provides an electromagnetically-opened fire-fighting smoke vent which comprises a smoke vent door frame body and a negative pressure exhaust pipe outside a ceiling, an integral smoke vent door plate is arranged at the joint of the smoke vent door frame body and the ceiling, a plurality of metal pull rods or inhaul cables are connected to the inner surface of the smoke vent door plate, and the other ends of the metal pull rods or inhaul cables are connected to the frame body. An electromagnetic door lock or a permanent magnet door lock which is demagnetized after being electrified is mounted on the inner surface of the smoke outlet door plate; the electromagnetically-opened fire-fighting smoke exhaust port is wide in application range, and can be suitable for fire-fighting accident smoke exhaust in areas with various cleanliness levels; a traditional mechanical mode is matched with the electric control door lock, rigidity is good, fixing is stable, reliability is high, and cost is low; the sealing degree is high, free communication with the outside world does not exist, the sealing performance is ensured, air leakage and seepage are avoided, the surface is smooth, dead corners do not exist, cleaning is easy, static electricity does not exist, and the influence of microorganisms, particles or residues on a clean area can be reduced to the maximum extent; the smoke exhaust efficiency is high, noise is avoided, installation is convenient, and installation space is saved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to an electromagnetically opened fire-fighting smoke outlet. Background technique [0002] Indoor fire accident smoke exhaust and general accident smoke exhaust are very important for the handling of safety production accidents. For the production of drugs (including veterinary drugs) or the clean areas of hospitals and electronics factories, the cleanliness of Class A, Class B, Class C, Class D, etc. In the high-level area, the partition from the external environment must ensure its airtightness, no air leakage, no seepage, smooth surface, no dead angle, easy cleaning, and no static electricity, which can minimize the impact of microorganisms, particles or residues on the clean area. The existing fan exhaust vents cannot ensure the required clean environment. [0003] Special auxiliary equipment must be used for fire accident smoke exhaust and general accident smok...

AI Technical Summary

Problems solved by technology

In the event of smoke exhaust in an accident, the smoke goes up quickly, so the most efficient and direct smoke exhaust outlet should be installed on the ceiling. Existing fire smoke exhaust windows and safety windows are generally installed on the side of the wall. Not high, and the use of motors will generate noise pollution

In addition, the sealing performance of the existing smoke exhaust outlets or smoke exhaust windows cannot meet the environmental requirements of high cleanliness requirements, and it is connected to or leaks from the outside air, causing pollution or impact on various products
