System for the visual inspection of the piping network of pneumatic urban solid waste collection facilities and procedure for identifying the position of points of interest in the pipeline carried out with said system.

摘要

For the visual inspection of the piping network of pneumatic urban solid waste collection facilities where a negative pressure/suction (PN/SU) is generated and said pipes to be inspected (Tu) an internal pipe diameter (Dt) and that are internally accessible through registration points (RTu) distributed throughout the installation, a system (1) with a cleaning head (2) in the form of a buoy driven by negative pressure/suction is provided; an image inspection and recording device (3) that is attached to the cleaning head (2) by a first cable length (L1) and a motorized drive mechanism (4) for winding/unwinding of the second cable length (L2), linked to the inspection device (3) at a drive speed (Va) essentially constant, so that the cleaning head (2) and the image inspection and recording device (3) can be moved forward/backward through the pipe to be inspected at a constant speed determined by said drag speed (Va) of the drag drum. In addition, the inspection device (3) consists of an external housing generally fusiform (30) and internally cylindrical inside which is disposed in a mobile manner, as a gyro, a mobile carriage (31) on whose carriage are mounted means of camera (310).
