Definitions

  • the invention relates to a remote-controlled inspection device for an annular combustion chamber of a gas turbine.
  • the invention further relates to a method for inspecting an annular combustion chamber of a gas turbine.
  • a device for inspecting tubes is known from US Pat. No. 4,255,762.
  • An optical system for taking test images of the inner surface of the tube is mounted on a test head of the device.
  • the test device has a positioning mechanism with which the test head can be moved in translation and rotation.
  • video images can be displayed in a tube surface.
  • the probe is guided in the tube without contact using a distance sensor.
  • DE 41 32 281 AI shows a drive unit for driving through a pipeline.
  • the drive unit has a drive, a plurality of sun wheels driven by the drive for rotation, in each case at least 2 planet wheels meshing with each sun wheel and a plurality of drive wheels with running surfaces. The treads are pressed against the inner wall surface of the tube by the orbital rotation of the planet gears.
  • a driving probe which is operated as an inspection device for driving through a pipeline network with bends and branches, consists of the coupling of two of the drive units described above.
  • the drive units are mounted on the front and rear ends of a flexible device. This enables a smooth passage through a pipeline network.
  • the object of the invention is to specify how the inspection of an annular combustion chamber of a gas turbine can be carried out quickly, inexpensively and in a particularly effective manner with regard to reliable fault detection.
  • a remote-controlled inspection device for an annular combustion chamber of a gas turbine which includes a remotely steerable drive mechanism, a movable video camera, a lighting device, a support frame for the video camera, the drive mechanism and the lighting device, and means for transmitting video images of the video camera has an evaluation.
  • a combustion chamber of a gas turbine is a very thermally highly stressed area.
  • Such a combustion chamber has a heat-resistant inner lining.
  • This inner lining is subject to considerable oxidation and corrosion. This leads to wear, which must be recognized at an early stage before there is consequential damage induced by wear.
  • complex coating systems for protecting the inner lining are often applied to them. Local chipping of this coating must be detected early and reliably.
  • Gas turbine burners which are also exposed to extremely high thermal loads, flow into the combustion chamber. In particular, the swirl grille of such a burner, which serves to generate a backflow stabilizing the combustion, must be regularly checked for wear.
  • the drive mechanism preferably has an electric motor and wheels, at least one of which wheels can be driven by the electric motor.
  • the inspection device is designed as a vehicle which moves independently through the ring combustion chamber on wheels.
  • the drive mechanism preferably has a, in particular C-shaped, rail with which the supporting frame can be moved.
  • the video camera mounted on the support frame with the lighting device is inserted into the combustion chamber via a C-shaped rail.
  • This rail can, for example, be telescopically extendable.
  • the drive mechanism preferably has an articulated arm on which the support frame is mounted.
  • This embodiment corresponds in its mode of operation to the extent that the video camera and the lighting system are introduced into the ring combustion chamber via a suitable point, for example the manhole, and are remotely steered by the ring combustion chamber is directed. In this case, too, no further exposure of the ring combustion chamber is necessary.
  • the object is further achieved according to the invention by a method for inspecting an annular combustion chamber of a gas turbine, in which a video camera is remotely steered into the annular combustion chamber and is pivoted such that video images of areas of the inner walls of the annular combustion chamber are recorded by the video camera, which video images are recorded an evaluation device positioned outside the annular combustion chamber can be transmitted.
  • a video camera is remotely steered into the annular combustion chamber and is pivoted such that video images of areas of the inner walls of the annular combustion chamber are recorded by the video camera, which video images are recorded an evaluation device positioned outside the annular combustion chamber can be transmitted.
  • FIG. 3 shows an inspection device arranged on a telescopic rail
  • FIG. 4 shows an inspection device with an articulated arm.
  • the power supply for the control and supply device 41 also takes place via the line 43.
