Definitions

  • the invention relates to a hose guide for a sewer inspection and / or maintenance system for deflecting leading to an inspection and / or maintenance device hose from a shaft into a channel, wherein between an arranged outside the shaft control device and located in the channel inspection and / or maintenance device a wireless communication link can be established.
  • Inspection and / or maintenance systems for inspection and / or maintenance of pipes or channels are known in the art.
  • a high-pressure hose is transported via a shaft (inspection shaft) into a channel branching from the shaft.
  • the hose can for example be pulled by a trolley in the channel.
  • a rinsing nozzle may be arranged at the front end of the hose.
  • an image pickup device such as a video camera.
  • the image data is then transmitted to an outside of the shaft control device, wherein the transmission can be done wirelessly.
  • deflection rollers may be arranged, for example, in order to avoid damaging the hose during deflection.
  • a deflecting mirror on the bottom of the shaft.
  • both the pulleys and the deflection mirror are designed as separate units and must be introduced separately from each other in the shaft.
  • care must be taken that, on the one hand, the deflecting mirror is not covered by the hose and / or by the deflection rollers.
  • the hose, the deflection rollers or other foreign objects located in the channel do not damage the deflection mirror.
  • it must be ensured that the deflection mirror is correctly aligned. It may therefore happen that the wireless communication link between the carriage and the control device is interrupted frequently, so that a complete monitoring of cleaning success during the cleaning process is not guaranteed.
  • a hose guide for deflecting a hose leading to an inspection and / or maintenance device from a shaft into a channel, the hose guide having a guide device.
  • the guide device has a predetermined radius of curvature such that a front portion of the guide device projects into the channel and a rear portion into the shaft, wherein the guide device deflects the hose from the shaft into the channel.
  • a camera is provided, wherein images from the camera are transmitted via a cable from the channel to a data acquisition and / or display system.
  • From the DE 10 2013 100 960 A1 and from the DE 10 2014 106 251 A1 are each an inspection and / or maintenance system is known in which data is transmitted via a cable or wirelessly from the channel to a control device arranged outside the channel. At the shaft, the cable is deflected. In the wireless variants, a repeater is provided in the region of the shaft floor, with which the signal is deflected.
