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 brought in the normal operation by the integrated actuator in the open position and held in this position. In the event of a fault or for the purpose of checking, the actuator should assume its safety position and be locked in this position against channel-side effects. The assumption of the safety position takes place when the power supply is interrupted, either by a power failure or by a targeted power interruption triggered via control electronics and sensors.
  • a safety actuator can be used, for example, to prevent the spread of fire and smoke in ventilation systems and seal openings for ventilation ducts in fire walls in the event of fire fireproof.
  • Actuators with spring return for fire dampers are well known in the air conditioning, ventilation and control technology.
  • the closest prior art is the patent application EP 0 699 095 B1 (D1).
  • 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 with walled fire damper.
  • most devices have relatively large dimensions and are expensive to manufacture due to their complex structure.
  • the locking in the open and in the safety position is often accomplished in practice also with elaborate inside or outside of the flap mounted rods. These rods make assembly difficult and must be adjusted. In addition, they are considered as moving parts and therefore pose a security risk.
  • the object of the present invention is to provide electrically operated fire dampers without the above-mentioned disadvantages of conventional systems.
  • the fire damper with actuator should be cheap, with as few moving parts can be made, the installation and removal should be possible in the simplest way, for example, with 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 the open position, the damper blade 11 is in the direction of the channel 2, so that substantially 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 can be brought with a substantially 90 ° rotation in the closing of the channel 2 security position without it touches the channel 2.
  • the damper blade 11 is rotatably supported, for example, about a vertical axis.
  • An overhead, partially inserted into a located above the opening for the channel 2 wall recess actuator 4 4 can rotate the damper blade 11 at a substantially right angle.
  • the actuator 4 is inserted during assembly of the flap 1 within a fire wall 5 only in a wall recess and then fixed to the torque fuse, for example with a screw 6, as far as possible the flap axis 3 and easily accessible to the channel 2. It is included in the idea of the invention that the actuator 4 can be mounted depending on accessibility even under the channel 2 or laterally on the channel 2 with horizontal flap axis 3.
  • a first embodiment of the damper blade 11 is shown in the safety position.
  • the damper blade 11 has a groove 7 at the top and bottom.
  • the flap axis 3 is not continuous over the entire channel height, but is formed by two short Achsend GmbHe 8 and the damper blade 11.
  • the Achsend thoroughlye 8 are non-positively connected, each with a direction perpendicular to the flap axis 3 mounted comb 13.
  • a pivot bearing 9 for example, a plain bearing, for receiving the lower Achsend thoroughlyes 8 admitted and the upper, for example, a square Achsquerrough having Achsend constitutional 8 is positively inserted into the hollow axle of the load torque lock 18.
  • the damper blade 11 can be inserted with the grooves 7 in the two ridges 13.
  • the grooves 7 are not continuous over the entire length of the damper blade 11, but they end on a blade half, depending on the length of the combs 13 so that the combs 13 strike in the correct position at the ends of the grooves 7. In this way, the damper blade 11 of a Side are pushed onto the combs 13, to the correct, defined by the ends of the grooves 7 position.
  • the comb 13 may also fill the groove 7 over the full width of the flap.
  • the damper blades 11 beat against the stops on the channel wall when taking the open position. These stops are not necessary here, since the actuator 4, the flap 1 exactly in the open position, usually in the direction of the channel 2, positioned and locked against forces acting on the damper blade 11 forces triggered torques.
  • the procedure for assembling the flap 1 is briefly summarized again.
  • the actuator 4 is inserted flush with mounting within a fire wall 5 in a wall recess on the channel 2 and secured with a screw 6 on the channel 2.
  • the actuator 4 is brought by power or manual winding in the open position, the two Achsend thoroughlye 8 are used in the bearings 9, 10, the damper blade 11 is retracted with the grooves 7 in the combs 13 of the Achsend suprae 8 and finally by means of compounds 12 and each after execution by means of guide members 24 attached to the Achsend congressen 8.
  • the assembly the actuator 4 and the damper blade 11 can be done completely from the side of the actuator 4 from.
  • Fig. 3 shows schematically the structure of a first embodiment of the actuator 4. It consists essentially of only four components.
  • An electric motor 15, which is coupled to the valve axis 3 with a spring return 16 and via a strongly reducing gear 17 (1: 500 to 1: 10'000) and a load torque lock 18. The required reduction of the transmission 17 depends on the performance of the electric motor 15. In normal operation, the electric motor 15 opens via the gear 17, the damper blade 11 and at the same time pulls the spring return 16.
  • the electric motor 15 is the actual drive source of the actuator 4. For starting and maintaining the open position of the damper blade 11, the electric motor 15 must be continuously supplied with power. Upon reaching the open position, the damper blade 11 and thus also the electric motor 15 is mechanically prevented from further rotation.
  • the further energized and now blocked electric motor 15 generates a sufficiently large torque to compensate for the restoring force of the tensioned spring return 16.
  • the tensioned spring return 16 rotates the damper blade 11 via gear 17 back into the closed safety position, wherein the electric motor 15 is also rotated backwards as a result of the fixed clutch.
  • a spring return 16 a coil spring is typically used, but there are also other springs for storing the required return energy conceivable and according to the invention.
  • For maintenance or commissioning with not standing power actuator 4 of the spring return 16 has a manual winding to open the damper blade 11, for example by means of a hexagon socket screw.
  • Lastmomentsperren 18 are prior art and are therefore not described in detail here. They allow an unimpeded drive of a machine part in both directions of rotation, while retroactive torques of the driven part are locked to the drive in both directions of rotation.
  • the load torque lock 18 thus allows free torque transmission in the drive direction, but blocks torque reaction from the drive part ago. It is necessary so that the damper blade 11 can not be moved by forces acting on it.
  • the electric motor 15 can also directly tension the spring return 16, which in turn is coupled to the flap axis 3 by means of the gear 17 and load torque lock 18.
  • FIG. 4 shows the load moment lock 18 mounted on the flap axis 3.
  • Mechanical stops 20 on both sides of a substantially rectangular segment, for example the output gear 25, make it impossible to overspeed the damper blade 11 when approaching the safety position or the open position.
  • These stops 20 of the driven wheel 25 in the actuator 4 make, as mentioned above, flap stops in the channel interior superfluous, which is reflected in simplified assembly.
  • the load torque lock 18 lying limit switches or sensors 21 are actuated, which can provide the information about the flap position, for example, to an electronic control system. However, this information can also be used for example for the regulation of the torque of the electric motor 15 in the open position of the damper blade 11.
  • this information can also be used for example for the regulation of the torque of the electric motor 15 in the open position of the damper blade 11.
  • For the fire protection function of the flap 1 limit switches or sensors 21 are not necessary.
  • Fig. 5 shows a first way, as a complete seal of the damper blade 11 in case of fire, can be achieved. This is done by means of thermally activated expanding Fabrics 14 which are attached, for example, to the flap leaf edges. These substances 14, for example foams, expand at high temperatures and thereby close off the remaining narrow gap between duct 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. In Fig. 6, another possibility for complete sealing of the damper blade 11 is shown in case of fire. The thermally expanding material 14 is applied to stops in the channel interior.
