摘要:
A system for inspection of a sewer network. The system comprises: a cleaning nozzle mounted on a hose; an inspection sled having a camera mounted thereon and a nozzle mounting section selectively engageable to the cleaning nozzle; and a position encoder configured to acquire position data representative of the position of the camera inside the conduit while the sled is moved inside the conduit by the movement of the cleaning nozzle and the camera captures images of the inner wall of the conduit. A method for inspection of a sewer network using the system is also provided.

A channel tube inspection device 1 includes an inspection head 3, a pushing cable 5 and an elongated intermediate part 7 whose one end 7a is connected to the inspection head and whose other end 7b is connected to the pushing cable. The intermediate part 7 has a radial rigidity or, worded differently, bending rigidity gradually increasing over its length. The bending rigidity of the intermediate part 7 gradually increases from the inspection head 3 to the pushing cable 6. The intermediate part 7 is solid and has a gradually diminishing diameter from the pushing cable 5 to the inspection head 3. The intermediate part 7 is made of plastic, preferably PUR.

A hydrodynamic apparatus for cleaning channels and for monitoring channels is provided for pipes and channels. A disadvantage of all conventional bottom floor cleaners, flushing heads, and channel-cleaning nozzles is that during the cleaning process no observation and determination of the soiling state or, respectively, of the cleaning state of the channel and no recognition of damaged areas in the channel is possible. According to the invention, a monitoring unit (6) is installed selectively in or at the channel-cleaning apparatus. For this purpose, for example, a hollow space (11) is furnished at the bottom floor cleaner (S), wherein the monitoring unit (6) is partly integrated into the hollow space (11). The monitoring unit (6) exhibits a camera module (7) or two camera modules (7a and 7b). A video emitter (15) is coordinated to each camera module (7). The transmission to a video receiver (V) is performed without cable wireless from the video emitter (15). The cleaning process can be followed in a monitor (M). As desired, also ballast material (12) can be filled into the hollow space (11).

A robot for the repair of sewer pipes comprises a carriage unit driven by a traction motor (2) arranged internally of a carriage housing (1) with wheels (7,9). The carriage housing (1) is connected to a rotary head (15) arranged immediately before the carriage housing (1). The rotary head (15), having tools and/or inspection devices mounted thereon, is driven by rotary motor (22). The traction motor (2) and the rotary motor (22) are arranged in a mutually overlapping relationship. The rotary head (15) is connected to a hollow shaft (23) extending through the whole carriage housing (1). The rotary head (15) is adapted for attachment of a robot arm carrying a tool support. A swivel arm of the robot arm as well as the tool support can be swiveled by hydraulic cylinders. The end of the robot arm facing away from the rotary head (15) is provided with a support wheel.

Detecting and locating leaks in building service lateral sewer pipelines is accomplished under remote control by inserting a lateral inspection television camera into the lateral pipeline from a main sewer pipeline. The lateral inspection camera is stored in a generally cylindrical launcher mechanism having a camera port opening through which the lateral camera may be projected and retracted using a hollow elongated and flexible push rod. The launcher is moved longitudinally in the main pipeline, along with a main television camera, until an entrance opening to a service lateral pipeline is viewed via the main camera. The launcher mechanism may also be rotated in order to properly align the camera aperture with the entrance to the lateral pipeline. The lateral camera can be propelled into the lateral pipeline by means of motor driven pinch rollers in the launcher mechanism pushing the push rod. Electrical power and video signals for the miniature camera are transmitted through a cable disposed within the push rod. An electronic switch is disposed in the launcher mechanism and is selectively actuable from a remote control station to effect alternative transmission of the lateral camera video signal and the main camera video signal to the remote control station.
摘要:
An inspection apparatus for underground channels such as sewer pipes and conduits for communication or electric cables and many other conduits for various utilities. The apparatus has a television camera which is adjustable in its position in accordance with the size of an underground channel, and a reversible motor which rotates V belts to advance and retract the apparatus in the underground channels. The television camera and the movement of the apparatus is controlled at a remote place.
