    Here, the reduced travel speed that can be achieved is posed as an additional problem to this physical effort, so that the pipeline inspection operation is time intensive, even for short journeys.
    The pneumatic waste collection networks consist of 500 mm diameter pipes, with junctions, branches and slope changes depending on the needs of adaptation of the network design, to the roads, buildings and areas to which it is intended to give service. Due to the particularity of the material to be collected, the intersections cannot be designed at a right angle, which produces considerable changes in the pipe plane when splicing the path changes, generating steps, vertices, to which it must be joined, the little adhesion of the material with which the pipe (steel) is manufactured and the accumulation, although small, of dirt on the walls of the same, making it even more difficult to pull the devices for displacement of conventional chambers and their drag on the inside of the pipe, aggravated this fact when it is intended to perform inspection without prior cleaning and there are considerable remains of MSW.
    Standard inspection systems are also known (see http: //www.panatec agua.com/Robot-Inspeccion-Rovver.php) which among others have the following disadvantages:
    - Difficulty / Impossibility in crossing the pipe junctions.
    - Difficulty / Impossibility of passing over accumulated waste.
    - Feed length limited by the drag that supposes the power cable, ends up ballasting the progress of the tested robots.
    - Pipe preparation times for inspection, (cleaning
    previous).
    JP S6038641 A, refers to a system for inspection of small diameter tubes with a photographic or TV camera to photograph the inside of the tube with the help of lighting means while compressed air is injected through an extendable tube to move the camera and using a mobile roller with a motor drive cable to move the camera that is mounted on a kind of skate.
    The documents US 4677472 and US 4991006, reveal respective devices for inspecting pipes of a pipe network that include chamber means for

    documents, the chamber means can be angularly oriented and driven into the side branches of a main pipe for visual inspection; It is represented as the chamber means are mounted on a kind of skate and are dragged along the pipe by means of a traction cable through a winch mechanism.
    In particular, in US 4991006 it is provided that the image collection chamber is driven into the pipe branch to be inspected using the pressure of a fluid generated by a pump type assembly associated with said chamber.
    In accordance with the above, the problems of impulsion and displacement of the camera device continue through a generally dirty conduction, with residues, and also to obtain sequences of recorded images for deferred inspection of the state of the pipe as well as the possibility to positionally reference points of interest within the pipeline for subsequent maintenance operations.
    Summary of the invention
    Starting from the state of the art described above, the invention aims to develop a system of the type indicated in a principle that allows solving or at least alleviating the drawbacks described above.
    This objective is achieved by means of a system as disclosed in the independent system claim 1. Other advantages and objectives of the system are achieved through the dependent claims of claim 1.
    According to the invention for the visual inspection of the pipe network of pneumatic urban solid waste collection facilities, whose installation allows to create a negative pressure / suction inside the pipe network and having said pipes to inspect an inside diameter of pipe and said pipes being internally accessible through registration points distributed throughout the installation, a system is provided comprising:
    - a cleaning head in the form of an inflatable buoy with an outside diameter in an inflated state, similar to the diameter of the pipe to be inspected, and said head being adapted to be driven by the negative pressure / suction produced by the pneumatic collection installation in the inside said pipeline to be inspected;

    - an image inspection and recording device that is connected to the cleaning head by means of a first cable length and adapted to move inside the pipe to be inspected;
    - a drive mechanism for winding / unwinding a second cable length, the terminal end of said second cable length being attached to said inspection and recording device;
    and whose system is characterized according to the invention because:
    - the image inspection and recording device is constituted by an external housing generally fusiform and internally cylindrical inside of which a mobile carriage is disposed in a carriage way in which carriage means are mounted camera means with wireless transmission-reception and timed image recording capabilities as well as lighting means and a power source for power supply, so that said car will occupy an essentially horizontal position regardless of the position of the outer shell inside the pipe to inspect, whereby the camera means occupy an essentially horizontal plane capturing images under said plane; Y
    - the drive mechanism is constituted by a motorized drive drum for winding / unwinding the second cable length at an essentially constant drag speed, so that the cleaning head in the form of a buoy and consequently the inspection device and Image recording can be moved forward / backward through the pipeline to be inspected at a constant speed determined by said drag speed of the drag drum.
    By using an inflatable buoy as the head of the system, the aspiration generated by the pneumatic collection system is used, ensuring the advance of the system and also dragging all types of waste material that could remain in the pipeline to be inspected and releasing the section so that the bearing housing of the visual inspection device can pass through said pipe without problems.
    Since the head and the inspection and recording device driven by the aspiration of the installation, are connected by a second section of cable to a
    5

    Cable drag mechanism with a drum governed with fixed speed and reversible movement, both directions (forward / reverse) of the head assembly and inspection device are allowed, either to clean, or to record / record images in time of any anomaly or breakage of the pipe structure.
    Since, in addition to the changes in the section / plane of the pipe network, the image inspection and recording device is arranged in a fusiform outer casing, possible traction wheels or chains are eliminated as well as edges that can rub on the pipe to be inspected; and since they are also mounted on a carriage inside the outer casing as a gyroscope, the image recording plane is always kept horizontal regardless of the relative position of the outer casing.
    According to an additional feature of the invention that makes it easy to place the cable sections, the external housing of the inspection device is provided with respective anchoring formations for fixing said first and second cable lengths.
    Also in accordance with another additional feature of the invention, the external housing of the inspection device comprises, at least one pair of rails, arranged according to internal diameters of said cylindrical housing parallel spaced apart and the mobile carriage comprising respective pairs of rolling wheels for moving through the aforementioned lanes.
    According to another additional feature of the invention to ensure proper operation and ease of operation, the power supply consists of at least one rechargeable battery, a start-up switch and a charging device.
    According to an additional feature of the invention and to ensure an adequate transition of the system along branch lines of the pipe network, the system is provided with a support buoy on the first cable length and inserted between the cleaning head and the inspection and recording device. Here, it may be additionally provided that a drag plate based on heavy material for friction, for cleaning purposes, on the inner surface of the pipe is arranged on the first cable length and inserted between the cleaning head and the support buoy to inspect.
    In operation once the cleaning head and the image inspection and recording device is inside the pipeline to be inspected and anchored to the

    dragging mechanism, the installation is started, which produces the aspiration of the cleaning head assembly and inspection and recording device along the pipeline to be inspected. By maintaining the assembly as a whole, its advance or recoil is achieved by releasing or collecting cable by means of the dragging mechanism and in this way the passage of the assembly through the pipe network is ensured, ensuring the inspection of sections with lengths even greater than 300 m in a single performance. In this way it is possible for the chamber to pass through all intersections, regardless of the slope and cleaning conditions of the pipe.
    Another additional object of the invention is a method for identifying the position of points of interest in the inspected pipe carried out with said inspection system described above. This objective is achieved through the corresponding independent procedure claim.
    According to the invention said procedure is characterized in that it includes steps of:
    - introduce a system through the installation registration point;
    - create a negative pressure / suction inside the pipeline to be inspected through the installation in order to drive the cleaning head;
    - move the image inspection and recording device along the pipeline to be inspected in advance-backward at the constant drag speed imposed by the drive mechanism; Y
    - record / record the images temporarily captured by the camera means during the movement of the inspection device, so that points of interest inside the pipe can be positionally identified by a distance depending on the elapsed time, recorded by the means of camera, from the beginning of the movement of the inspection device until the visualization of said point of interest.
    Since with the cable drag mechanism with a motorized drum, a uniform speed is achieved, and since the recording of images inside the pipe is carried out with video time measurement, length measurement is possible, taking as reference network elements such as inspection records, mailboxes, branches etc., here indicated generically as points of interest of the pipe.
