Definitions

  • the present invention relates to an electrically driven Fire damper according to the preamble of claim 1.
  • Fire dampers with actuators and spring return are used as safety actuators.
  • the actuators are in normal operation by the integrated actuator placed in open position and held in this position. in the Incident or for verification purposes, the actuator should be its Occupy security position and in this position opposite Channel-side actions are locked.
  • the ingestion the safety position takes place at interruption of the Power supply, either through a power outage or through a targeted, via control electronics and sensors triggered Power failure.
  • a safety actuator can for example, the spread of fire and to prevent smoke in ventilation systems and breakthroughs for ventilation ducts in fire walls in case of fire fireproof seal.
  • Actuators with spring return for fire dampers are in the air conditioning, ventilation and control technology well known.
  • D1 discloses a fire damper with associated control system for at least one flap.
  • a disadvantage of the known fire dampers is the complicated and time-consuming factory Assembly and disassembly of the flap and the actuator and the replacement of the actuator due to maintenance at walled fire damper.
  • the Lock in the open as well as in the safety position In practice it often comes with a complex interior or externally attached to the flap mounted poles accomplished. These rods make assembly difficult and must to be adjusted. In addition, they are considered moving parts and therefore pose a security risk.
  • the object of the present invention is to provide of electrically operated fire dampers without the above-mentioned disadvantages of conventional systems.
  • the fire damper with actuator should be cheap, with as little as possible movable parts can be made, the installation and expansion should be possible in the simplest way, for example even with a walled fire damper.
  • the actuator should also be as compact as possible.
  • Fig. 1 shows a first embodiment of a fire damper 1, hereinafter called flap 1.
  • flap 1 In open Position is the damper blade 11 in the direction of the channel 2, so that essentially the whole, here rectangular, cross-section of the channel 2 is released.
  • the damper blade 11 has the same geometric shape as the cross-section of the channel 2, but is so much smaller that the damper blade 11 with a essentially 90 ° rotation into the channel 2 closing Security position can be brought without it touched channel 2.
  • the damper blade 11 is for example rotatably mounted about a vertical axis.
  • An overhead, partly located in a channel above the breakthrough for the channel 2 Wall recess inserted actuator 4 can Turn damper blade 11 about a substantially right angle.
  • the actuator 4 is in mounting the flap 1 within a fire wall 5 only in a wall recess inserted and then to the torque lock, for example, with a screw 6, as far as possible Flap axle 3 and easily accessible fixed to the channel 2. It is included in the idea of the invention that the actuator 4 each after accessibility also under the channel 2 or laterally on Channel 2 with horizontal flap axis 3 are attached can.
  • Fig. 2a, b is a first embodiment of the damper blade 11 shown in safety position.
  • the damper blade 11 has a groove 7 at the top and bottom.
  • the flap axis 3 is not continuous throughout the channel height, but will formed by two short Achsend GmbHe 8 and the damper blade 11.
  • the Achsend thoroughlye 8 are non-positively with one each attached to the direction of the flap axis 3 at right angles Comb 13 connected.
  • a pivot bearing 9 for example, a sliding bearing, embedded for receiving the lower Achsend GmbH 8 and the upper, for example, a square axle cross-section having Achsend constitutional 8 is positively in the hollow axle the load torque lock 18 introduced.
  • the Damper blade 11 is inserted with the grooves 7 in the two ridges 13 become.
  • the grooves 7 are not over the entire length of the Damper blade 11 continuously, but they end on a Flap half, depending on the length of the combs 13 so that the Combs 13 in the correct position at the ends of the grooves. 7 attacks. In this way, the damper blade 11 of a Side be pushed onto the ridges 13, to the correct, defined by the ends of the grooves 7 position.
  • the properly positioned and adjusted damper blade 11 can then at the ridges 13 and thus at the Achsend constitutionalen. 8 fixed by means of a compound 12 and so against subsequent horizontal shifts are saved.
  • This connection 12 for example, by means of screw directly into the Comb 13 done.
  • Another embodiment of the invention for preventing displacement of the damper blade in Direction of the groove 7, is that frictionally with the axle end piece 8 connected U-shaped guide parts 24, For example, made of sheet steel, the damper blade 11th close to the axis and these guide parts 24 at right positioned damper blade 11 with the damper blade 11 by means of Connections 12 are connected.
  • the comb 13 can the Fill groove 7 also over the full width of the flap.
  • the actuator 4 is at Installation within a fire wall 5 flush in one Wall recess inserted on the channel 2 and with a screw 6 attached to the channel 2. Subsequently, the actuator 4 by power or by manual winding in open position brought, the two Achsend thoroughlye 8 are in the camp 9, 10 inserted, the damper blade 11 is with the grooves 7 in the combs 13 of Achsend suprae 8 retracted and finally by means of connections 12 and depending on the design by means of guide parts 24 attached to the Achsend congressen 8. The assembly the actuator 4 and the damper blade 11 can completely take place from the side of the actuator 4 from.
  • Fig. 3 shows schematically the structure of a first embodiment the actuator 4. It consists essentially from only four components.
  • the required reduction of the transmission 17 depends on the performance of the Electric motor 15 off. In normal operation, the electric motor opens 15 via gear 17, the damper blade 11 and pulls simultaneously the spring return 16.
  • the electric motor 15 is the actual one Drive source of the actuator 4. For starting and getting the open position of the damper blade 11 must the Electric motor 15 are continuously powered. at Reaching the open position, the damper blade 11 and thus Also, the electric motor 15 mechanically prevented from turning further.
  • the further energized and now blocked Electric motor 15 generates a sufficiently large torque to to compensate for the restoring force of the tensioned spring return 16.
  • the cocked turns Spring return 16 the damper blade 11 via gear 17 in the closed safety position back, the electric motor 15 due to the fixed clutch also backwards is turned.
  • spring return 16 is typically a Spiral spring used, but there are other springs for Storage of the required return energy conceivable and according to the invention.
  • actuator 4 has the spring return 16 via a manual winding to open the damper blade 11, for example by means of a hexagon socket screw.
  • Lastmomentsperren 18 are prior art and therefore not described in detail here. They allow one unimpeded drive of a machine part in both Turning directions, while retroactive torques of the driven Partly locked to the drive in both directions of rotation become.
  • the load torque lock 18 thus allows free torque transmission in the drive direction, but locks Torque reaction from the drive part. It is necessary so that the damper blade 11 is not by forces acting on it can be moved.
  • spring return 16 and strongly reducing gear 17 are the Professional known many variants. These are in the spirit of the invention including.
  • the electric motor 15 also directly tension the spring return 16, which in turn by means of gear 17 and load torque lock 18 with the Damper shaft 3 is coupled.
  • Fig. 4 shows the mounted on the damper shaft 3 Lastmomentsperre 18.
  • Mechanical stops 20 on both sides of a substantially rectangular segment, for example the output gear 25, make impossible over-rotation of the damper blade 11 when approaching the safety position or the open position.
  • limit switches or sensors 21 actuates which information about the flap position for example, to an electronic control and regulation can deliver. This information can but for example also for the regulation of the torque of the electric motor 15 are used in the open position of the damper blade 11.
  • limit switches or sensors 21 are not necessary.
  • Fig. 5 shows a first possibility, such as a complete Seal of the damper blade 11 in case of fire, can be achieved can.
  • This is done by means of thermally activated expanding Substances 14, which, for example, on the flap leaf edges are attached.
  • These substances 14, for example Foams expand at high temperatures and close thereby the remaining narrow gap between the channel wall and damper blade 11 airtight. The process is irreversible.
  • the now glued flap leaf 11 must then be broken out and replaced with a new one.
  • Fig. 6 is another way to complete the seal of the Damper blade 11 shown in case of fire.
  • the thermally expanding Fabric 14 is applied to stops inside the channel.
