Definitions

  • the invention relates to a drive unit for a flap in a smoke extraction duct of a fire protection system.
  • the invention is therefore based on the object Specify drive unit that is suitable for the actuation of Smoke control dampers are suitable. This task is accomplished by the Features solved in the characterizing part of claim 1.
  • Fig. 1 shows a simplified example of a building with three superimposed rooms 1a, b, c.
  • a supply air duct 2 with a fan 3 supplies rooms 1a, b, c via Supply air spigot 4a, b, c with fresh air.
  • An exhaust air duct 6 leads accordingly with a fan 7 used air from rooms 1a, b, c, with which he over Exhaust port 8a, b, c is connected from.
  • the Exhaust ports 8a, b, c are with fire dampers 9a, b, c Mistake.
  • a smoke extraction duct 10 with a Fan 11 provided. Rooms 1a, b, c are with the Smoke extraction duct 10 via smoke extraction nozzle 12a, b, c connected, in which smoke extraction dampers 13a, b, c installed are.
  • the fire dampers are normally open and the Smoke control dampers closed, as in the upper room 1a and at the lower room 1c, where the Fire dampers 5a, 9a, 5c, 9c are open and the Smoke control dampers 13a, 13c are closed.
  • Kick like shown in the middle room 1b a fire started by Temperature sensors and smoke detectors are detected, so the fire dampers (here 5b, 9b) immediately closed while the smoke extraction damper 13b is open becomes. Further oxygen supply through supply air duct 2 or Spread of fire in other rooms via the exhaust air duct 6 is prevented.
  • smoke is caused by the Opened smoke extraction damper 13b removed. A spread of smoke in rooms 1a, 1c not affected by the fire via the smoke extraction duct 10 through the Smoke control dampers 13a, 13c, which remain closed, prevented.
  • the drive units of the fire dampers 5a, b, c, 9a, b, c and the smoke control dampers 13a, b, c are usually over a separate system powered and are at least functional at the start of the fire. You take the above positions described and shown in Fig. 1. If a power failure occurs later, the Ensuring the most effective isolation of the Spaces against each other and to prevent Oxygen supply only too late from Fire-rated rooms all fire dampers conclude.
  • the smoke extraction dampers are said to be in the rooms already covered to ensure a minimum of partial smoke extraction remain open while the rest to prevent the spread of smoke and any toxic gases released by the fire should remain closed. Closing the Fire dampers are replaced by return springs in the Drive units achieved this in a basic position bring in which the fire dampers are closed, while the smoke extraction dampers are in the desired Positions are held by the drive units blocked in the position you are currently in become.
  • a drive unit for smoke extraction dampers can are basically built the same, but without Return spring, therefor with a locking device, which blocks the drive unit in the event of a power failure ensures (Fig. 2, 3a, b).
  • gearbox which has an electric motor of the drive unit connects an output that is used directly on the Smoke control damper acts on a locking device.
  • she includes a gear 14 which is part of the transmission and with the output is in a positive operative connection. It is firmly connected with a coaxial locking ring 15 and forms with the same a locking crown 16 with the one Locking pin 17 can engage.
  • the locking ring 15 is uniformly over for this purpose with a number provided its circumference distributed locking holes 18.
  • the Gear 15 is non-rotatable on a coaxial pinion 19 attached, which with an electric motor Drive unit is in operative connection.
  • the mechanical Active connection between the electric motor and the output So runs on the pinion 19 and the gear 15 on a fixed shaft 20 are rotatably mounted together.
  • the locking pin 17 is near the edge the same on a disc-shaped anchor plate 21 attached ferromagnetic material and protrudes against the Locking ring 15 before.
  • the anchor plate 21 is between the locking crown 16 and an electromagnet 22 the shaft 20 through a central recess of the Armature plate 21 protrudes, axially limited slidably mounted.
  • the electromagnet 22 with a housing 23 wound coil 24 and a sleeve-shaped core 25 Ferromagnetic material also surrounds the shaft 20 coaxial.
  • the anchor plate 21 is against rotation secured because the housing 23 in turn over another Extension 28 with a non-rotatable on the shaft 20th attached sleeve 29 engages.
  • Coil spring 30 exercises on the anchor plate 21 against the Locking crown 16 aligned pressure.
  • On a tab 31 of the anchor plate 21 is an unlocking pin 32 attached.
  • the locking pin 17 either directly with one of the Locking holes 18 or he is against the top of the Locking ring 15 pressed until after any short further rotation of the locking crown 16 with one of the Locking holes 18 come to coincide and engage.
  • the any mobility of the downforce and thus the Smoke control damper after a power failure is in in any case limited to a narrow interval. If this limited freedom of movement is necessary restrict further, e.g. B. by using a Tooth coupling instead of the locking ring and Locking pin. By pulling the release pin 32 the drive unit can be unlocked manually.
