Definitions

  • the present invention relates to a method for actuating at least one fire damper, in which the flap is then actuated when a change is made to a component that changes mechanically under thermal load, and a device for this purpose with at least one component that changes mechanically under thermal load and one for the change responsive control circuit for the flap.
  • an electrical thermal switch which closes a circuit at a certain ambient temperature, in which a component, a wire, is provided which is heated by the onset of the current flow.
  • the wire changes due to the current-related thermal load and expands.
  • the wire is connected on one side to a pawl arrangement on which a weight connected to a flap is suspended. For a given change, i.e. Expansion of the mentioned wire, the pawl arrangement is released and the weight closes the flap.
  • the present invention aims to provide a method or a device of the type mentioned at the outset, which is self-contained and works without any auxiliary energy supplied. This is achieved by the method according to claim 1 or by the device according to claim 6.
  • the invention is therefore based on the insight that components such as metal bodies, closed gas volumes etc. change fundamentally under thermal stress, such as their viscosity, their state of matter, their volume, according to material-specific constants. For example, the internal pressure of a constant gas volume increases with increasing thermal load. This thermal behavior is exploited according to the invention by evaluating the corresponding change.
  • Particularly suitable metal alloys have been created for this purpose, for example the article "memory effect and technically applicable Alloys "from G. Rau, Pforzheim, by Dr. P. Tauzenberger and Prof. Stöckl, Pforzheim.
  • Another object of the present invention achieved by designing the method or the device according to claims 4 and 18 respectively, consists in being able to check the functionality of the fire damper actuation remotely, which is basically achieved by simulating a thermal load on the changing component through controlled loading, such as by means of a heating element.
  • FIG. A component 3 is mounted on a reference system 1, on its one base surface 5.
  • the component 3 is made of a material that changes shape under thermal stress e , as it extends in the direction x indicated. Depending on the material selected for component 3, this variation in expansion is larger or smaller.
  • They are so-called memory alloys, such as those mentioned in the aforementioned "Memory Effect and Technically Applicable Alloys" by Dr. P. Tautzenberger and Prof. Dr. D. Stöckel, Pforzheim, known, whose thermal deformation can be influenced selectively and up to relatively large values by the choice of alloy.
  • a lever 7 acting as a scanning device converts the thermally induced expansion of the component 3 into a translated displacement k ⁇ x ( ⁇ ).
  • the two-armed lever 7, at its lever end facing away from component 3, has a locking or releasing effect on a fire damper 11 that is prestressed by means of a spring 9.
  • a pawl 13 snaps out counter pawl 15 provided at the lever end and the fire damper 11 is closed by pulling the spring 9 in the indicated direction.
  • component 3 detects the thermal load ⁇ H incident from the environment.
  • a heating element is generally provided in the region of component 3, such as a resistance element 18 which is connected via a feed 19 is operated.
  • the B is applied au- element 3 with a thermal stress test T.
  • the device 3 and the utilization of its thermal deformation ensures that the function of the actuator assembly can be nondestructively tested at any time, via the provided heating element, and that whatever the S chliessung during a test operation, a thermal fire attack of the fire damper 11 performs.
  • the scanning device formed by the two-armed lever 7 of F ig can. 1, triggered manually at any time, to close the fire damper 11.
  • the scanner lever 7 is provided with a clutch fork 23 at the end. It acts in an axially displaceable manner on a drive axle 25 which is driven by an output shaft 29 of an electric motor 27.
  • the axially displaceable axis 25 carries at the end a clutch disc 31, which cooperates with a clutch disc 33, mounted on an axis 35 carrying the fire damper 11.
  • a spiral spring 37 drives the axis 35 with the fire damper 11, as soon as the coupling 31, 33 is disengaged, into the closed fire damper position, as indicated by the arrow F.
  • the lever acting as a scanning device 7 disengages the clutch 31, 33, may be sampled at a certain extent increase the component 3, on the other hand both manually, as based on F ig. 1, the fire damper 11 can be closed, by uncoupling the coupling 31, 33 and further, the fire damper 11 can be motor-driven, via the motor 27, the output shaft 29 and axes 25, 35 at any time selectively closed or opened again.
  • FIGS. 3 and 4 An implemented exemplary embodiment of the present invention will now be described with reference to FIGS. 3 and 4.
  • a rocker arm 43 is pivotally mounted on pivot axes 41 parallel to the plates 39 and is moved in the direction of the lower plate 39 by means of a spring 45 4 is prestressed.
  • the free end of the rocker arm 43, designated A corresponds to the output of the device, in analogy to the fork 23 of the schematic representation of FIG. 2, and acts on a coupling on the axle 25, which is not shown for reasons of clarity.
  • the upper side of the rocker arm 43 lies against a lower edge x of a transfer lever 47, as can be seen in particular in FIG. 4.
  • the transfer lever 47 is pivotally mounted parallel to the plane of the plates 39 on an axis 49 perpendicular thereto and carries a tensioning lever 51.
  • the latter is rotatably mounted on the lever 47 about an axis 50 and is biased against the axis 25 by means of a spring 52.
  • the interaction of the transfer lever 47 and rocker arm 43 is such that the free end A of the lever 43, when the operating lever 47 is in its left position L according to FIG. 3, is driven into the lower position U according to FIG. 4 and by the force of the Spring 45 in its upper position 0, when the transfer lever 47 is moved to its right position R.
  • This is due to the interaction of the lower edge x on the lever 47 and a bevelled part 57 on the rocker arm 43, as shown in FIG. 4 evident, reached.
  • the rocker arm 43 rides at the end and lying in the direction of a spring force F 45 , on a guide curve 59 of a cam wheel 61, the latter being rotatably mounted between the housing plates 39.
  • the cam wheel 61 is operatively connected to the rocker arm 43 by two actuating cams 65, the latter being pressed against the guide curve 59 by the action of the spring 45.
  • an upstanding bolt 69 with an end collar 71 is provided on the housing.
  • a bolt 73 rides on the bolt 69, axially displaceable, provided on the one hand with an abutment surface 75, and on the other hand with a control collar 77 to be described function.
  • a spring 81 made of a memory alloy is provided on the bolt 69, which expands relatively strongly under thermal stress in the axial direction of the bolt 69 and contracts in at least almost the same original length after removal of the thermal load .
  • the axial distance between the end collar 71 and the abutment surface 75 is changed, that is to say the bush 73 is displaced accordingly on the bolt 69.
  • the sleeve 73 rests on a prestressing spring 79, against which the spring 81 made of memory alloy thus works.
  • the locking section 53 can ride both on the control collar 77, then the lever 47 is in position R or, if the lever 47 in the The position L is pivoted, which is shown in FIG. 3, the latching section 53 rides on the small-diameter part 80 of the sleeve 73.
  • a tensioning disk 62 On the axis 25 rides further, in this respect non-rotatably, a tensioning disk 62 with a tensioning notch 68.
  • the notch 68 acts on the transmitter 47 via the tensioning lever 51 and drives it into the right position R.
  • the end A of the lever 43 In order to enable the fire damper to be opened, the end A of the lever 43 must now be driven into the upper position 0, with which, in analogy to FIG. 2, a coupling provided, designated 31, 33, is coupled to the axis 25, and how the fire damper 11 can be opened by means of a motor 27 from FIG. 2.
  • This movement of the end A from U to 0, which only enables opening, is achieved by turning the turnbuckle disk 62 driven.
  • the tensioning pulley 62 is initially rotated clockwise, so that when the notch 68 occurs on the surface 64 of the lever 51, due to the force acting on the axis 50 and a corresponding moment with respect to the axis 49, the transmission lever 47 counteracts the force of the spring 67 in it Position R is driven.
  • the tensioning lever 51 initially remains with its surface 64 during the pivoting of the transfer lever 47 in the direction R in the notch 68 and takes up the pivoting of the lever 47 by relative relative pivoting about the axis 50 without any significant change in its absolute position. Only when the lever 47 is pivoted relative to the tensioning lever 51 is the latter pulled out of engagement with the notch 68 by a driver 66 on the lever 47 and then swung out by the spring 55 to such an extent that the surface 64 is no longer in the path of movement of the notch 68 lies.
  • the bushing 73 also the collar 77, is driven axially upwards according to FIG. 4 against the force of the spring 79 via the abutment surface 75, whereupon the surface 53 of the lever 47 springs back onto the small-diameter neck 80 of the sleeve 73.
  • This driven by the spring 67, causes the lever 47 to pivot into its position L, which in turn, by acting on the beveled part 57 on the lever 43, pivots the latter into its position U: the coupling provided, e.g. 31, 33 of Fig. 2, is released and the fire damper 11 pops, driven by the spring 84 or by its own weight, in the closed position.
  • the arrangement must be actuated or tensioned again, as described above, via tensioning disk 62, i.e. the lever 47 in position R, thereby lever 43 is moved to position O, and, as with the electric motor 27 provided in FIG. 2, the flap is opened again.
  • the drive motor for the flap acts on the axis 86, on the axis 25 the tensioning disk 62 also acts as a tensioning motor.
  • the device is initially tensioned with the motor provided via the axis 25 and the tensioning disk 62, as a result of which the lever 51 is pivoted in the manner described above from the path area of the notch 68 on the tensioning disk 62.
  • the axis 25 can now be motor-driven, rotated as desired, with the device still tensioned, with which the fire damper axis 86 is rotated via gear 82, opening or closing.
  • the thermal sensor S spring 81 thermally stressed to simulate the fire case. Exactly the same as in the event of a fire, the fire damper 11 is thereby driven into its closed position by decoupling. This enables the device function to be checked properly.
  • the rocker arm 43 can also be pivoted manually or motor-driven at any time into position U by turning the cam wheel 61, as indicated by the arrow M, whereby, as mentioned, the fire damper is released for spring-driven closing.
  • the lever 47 is in its position R, is fixed there by the collar 77 and the latching section 53, the lever 43 can be pivoted to U at any time by turning the cam wheel 61.
  • the coupling 31, 33 provided is released and the flap thus closes.
  • the sensor spring 81 thus acts as the component whose spanned volume, which changes under thermal load, is used as a control signal for actuating the fire damper.
  • the heating which can be actuated via the cables 83, such as a resistance element integrated in the bolt 69, enables the device to be checked properly.
  • the spring 81 is constructed from a memory alloy and thus results in a relatively large, thermally induced stroke.
  • the stroke of the spring 81 is transmitted to the bush 69 with the collar 77, against which the surface 53 of the spring-loaded lever 47 rests.
  • the axial length of the collar 77 thus forms a threshold unit in that the lever 47 only swings into its position L when the spring 81 has carried out a stroke corresponding to the axial length of the collar 77.
  • This collar thus converts the continuous expansion signal of the sensor spring 81 into an "on / off" signal.
  • the device described in FIGS. 3 and 4 is constructed with the sensor element 81 acting as the mentioned component and with the scanning device, formed by bush 69, collar 77 and lever 47 as a module-like unit, with its output, formed by lever arm A. of the lever 43, which is designed accordingly, can be mounted on the fire damper arrangement with the coupling provided, as has been described with reference to FIG. 2.
  • the coupling connecting the gear 62 and thus the fire damper on axis 86 to the engine output axis 25 is closed as long as the fire damper is to remain open.
  • the flap 11 is otherwise closed by releasing the coupling provided, driven by the spring 84.
  • Record preopened flap position in other words, has the intended acting on the motor shaft 25, the torque of the strong spring 84 in ge.
  • a latching device is provided which acts on the output axis 25 and takes up the torque mentioned by latching in as long as the motor is not being actuated.
  • this latch arrangement comprises, for example, a plunger armature arrangement 90 with an electromagnet 91 and an armature 92.
  • the electromagnet arrangement 91 pulls the plunger armature 92 out of engagement with the axis 29 as soon as the motor, as with a switch S, is connected to the electrical supply 93 becomes.
  • the motor 27 of FIG. 2 is not activated, the armature 92 then extended to the right, for example engaging in a toothing 94 on the axis 29, blocks its rotary movement and thus takes the restoring moment of the then tensioned spring 37 when the flap 11 is open on.
