    description
    TECHNICAL FIELD The present invention describes a pressure medium-operated pipe cleaning device, comprising a nozzle module and a camera module, the nozzle module comprising a plurality of thrust nozzles and a plurality of cleaning nozzles, and the camera module comprising at least one camera, a lighting device, control electronics, a memory, and one Has transmitter and a battery, so that the camera module can be controlled from the outside by accessing the control electronics.
    PRIOR ART Pipe cleaning devices operated by pressure medium, which are operated by means of a pressure medium or cleaning fluid, usually water, under pressures from a few bar to a few hundred bar, have long been known from the prior art. Such pipe cleaning devices can be used to clean pipes and ducts in industrial plants, duct installations in the public sector and in private areas.
    To control the cleaning result companies offer to control the cleaned pipes and channels with a camera, which is done after cleaning. A camera module with a camera is guided through the cleaned pipe or channel after cleaning, whereby pictures of the cleaned inner walls are taken and the cleaning result is documented. This additional step is of course associated with additional costs, which one would like to minimize.
    Accordingly, manufacturers of pipe cleaning devices have set out to equip pressure-medium-operated pipe cleaning devices directly with a camera, so that a video of the cleaning result can be made during or shortly after the cleaning. Pipe cleaning devices of this type were equipped with a camera module, the power supply and the data transmission of the camera module having to be optimized before desired videos can now be made in the pipe or channel. In order not to disturb the video recording, non-rotating nozzle modules of the pipe cleaning devices with an integrated camera module were used. Although these allow a desired video recording, the cleaning effect of these pipe cleaning devices is poor.
    The person skilled in the art has recognized that rotating pipe cleaning devices must be used in order to achieve a desired cleaning effect. A camera module has been integrated in the rotating pipe cleaning device. The rotation of the pipe cleaning device with an integrated camera module, however, makes it more difficult to record video images. In order to solve this problem, technically complex solutions were tried which synchronize the image recording with the rotational speed in order to achieve a still video image. The resulting video quality is disadvantageous in addition to the annoying additional technical effort.
    The present invention has for its object to provide a pipe cleaning device that has optimal cleaning properties with streak-free cleaning of the pipe and channel wall and at the same time allows video recording of the entire cleaning process, which is achieved with little technical effort at low adaptation costs shall be.
    Due to a modular design of the pipe cleaning device and the separation of a camera module and a rotatable nozzle module, and their linear spacing, flexible pipe cleaning adapted to the intended use with simultaneous video control is possible.
    In addition, a robust pipe cleaning device is achieved which can be subjected to high pressures and cleans reliably even under extreme conditions, the nozzle module and the camera module being mechanically adequately protected.

    CH 712 694 A2
    Description A pipe cleaning device 1 is described, comprising a nozzle module 2 and a camera module 3, which are mechanically attached to a carriage 4, spaced apart from one another in the direction of the longitudinal axis L. A carriage 4 is understood here as a holding device for fastening the components, which favors a linear movement of the pipe cleaning device 1.
    The nozzle module 2 comprises a rotatably immovable stator part 20 and a rotor part 21 which can be rotated about the longitudinal axis L of the nozzle module 2 by supplying a cleaning fluid. The cleaning fluid, usually fresh water or recycling water, is introduced into the stator part 20 by means of high-pressure line 5 under liquid pressures from 50 bar to a few hundred bar or even 1000 bar.
    The stator part 20 of the nozzle module 2 and a housing 30 of the camera module 3 are spaced from each other in the direction of the longitudinal axis L by a retaining ring 41 or a holding sleeve 41 on the carriage 4 rotatably and linearly immovable. A gap is arranged between the rotor part 21 and the housing 30 of the camera module 3. The rotor part 21 can, as indicated by a dashed arrow, rotate about the longitudinal axis L.
    The carriage 4 has at least one runner 40 to which the retaining rings 41 or retaining sleeves 41 are attached directly or indirectly. Here two runners 40 are arranged approximately in a V-shape with respect to one another. A front strut and an inlet-side strut run on each runner 40 to the connecting retaining ring 41 or the holding sleeve 41. The retaining rings or sleeves 41 are welded to the slide 4 or the runners 40. Nozzle module 2 and camera module 3 are preferably screwed into the retaining ring or sleeve 41 with screws. The nozzle module 2 and the camera module 3 can thus be connected to the slide 4 in an exchangeable manner. A simple replacement is interesting for maintenance purposes or repairs.
    A plurality of protective brackets 42 are provided which span the runners 40, the nozzle module 2 and the camera module 3, whereby contact of these components with a duct or pipe wall can be prevented. Here, the protective brackets 42 protrude from the slide 4 and protrude beyond the protective glass side of the camera module 3 and in the longitudinal direction beyond the camera module 3 and the nozzle module 2, the protective brackets 42 being at a distance from the modules. On the underside of the slide 4, the runners 40 space the modules 2, 3 from the floor, which can be seen in FIG. 4. The protective brackets 42 can, for example, be welded to the runners 40 or hooked into suitable cutouts on the runners 40 and clamped in the runners 40 under tension. The protective brackets 42 are preferably curved without edges so that no disruptive edges can get caught on the inner wall of the pipe or channel.
    It was the goal to form robust rotating pipe cleaning device 1, which has a desired cleaning and flushing performance. A rotating drive of the nozzle module 2 or of the blank 21 is absolutely necessary for this.
    In order to achieve the advance of the pipe cleaning device 1, a plurality of thrust nozzles 200 on the stator part 20, the camera module 3 is arranged opposite. These thrust nozzles 200 ensure a linear advance of the pipe cleaning device 1 in the direction of the longitudinal axis L through the pipe to be cleaned. The thrust nozzles 200 are aligned at a thrust nozzle angle greater than zero with respect to the longitudinal axis L. The flow rate or pressure of the cleaning fluid is optimized for maximum feed.
    On the rotor part 21, a plurality of cleaning nozzles 210 are arranged, which bring about the rotation of the nozzle module 2. The cleaning nozzles 210 are directed radially away from the longitudinal axis L of the nozzle module 2, so that rotation of the rotor part 21 about the longitudinal axis A can be achieved at high speed when pressure is exerted by escaping fluid. The cleaning nozzles 210 are arranged inclined to the longitudinal axis L. In addition, the cleaning nozzles 210 release cleaning jets that strike the inner walls of the channels or pipes at different angles. The cleaning nozzles 210 are arranged slightly offset in the direction of the longitudinal axis A and have different cleaning nozzle angles, so that the emerging cleaning jets strike the channel or pipe inner wall along the longitudinal axis A with a slight offset. This achieves a maximum cleaning effect. Streak-free cleaning of the interior walls can be achieved.
    While the rotor part 21 rotates about the longitudinal axis L and the stator part 20 is fixed to the carriage 4 in a rotationally and stationary manner, the camera module 3 is also mounted in a stationary and rotational manner on the carriage 4.
    In the housing 30 of the camera module 3, a lighting device 31, a camera 32, control electronics 33, a memory 34, a transmitter 35 and a battery 36 are housed. The end of the housing 30 is formed by a protective glass 320 which protects the camera 32 during operation and is not scratchable. Protective glass 320 is preferably formed from sapphire glass. The lighting device 31 can be formed by LEDs, by means of which strong illumination is possible with little energy consumption. The lamps of the lighting device 31 are preferably arranged in a ring around the camera 32 directly behind the protective glass 320. The control of the lighting device 31, the memory 34, the transmitter 35 is achieved by the control electronics 33. The images recorded by the camera 32 can be stored in the memory 34 and transmitted wirelessly from the sewer or pipe by means of the transmitter 35. Since wireless data transmission is provided and the power supply to the components of the camera module 3 is achieved via the battery 36, no disruptive cables need to be laid, as a result of which an extremely robust pipe cleaning device 1 is achieved.
    CH 712 694 A2 With a mobile device, a user can operate the camera module 3 or the control electronics 33 from outside and control the current cleaning process with the camera 32. The recorded videos can be stored permanently in the memory 34, so that the recorded images can also be read out after the cleaning process, after the pipe cleaning device 1 has been removed from the pipe or channel.
    3, a distance a between the nozzle module 2 and the camera module 3 can be seen in the direction of the longitudinal axis L. Due to the upstream longitudinal camera module 3, the separate design of the pipe cleaning device 1 with separate nozzle module 2 and camera module 3 and the linear spacing of the nozzle module 2 and camera module 3, the nozzle module 2 can be equipped with a rotatable rotor part 21, with which an optimized cleaning performance and easy recording of videos can be reached.
    In operation, the pipe cleaning device 1 is inserted into a channel or a pipe and then the nozzle module 2 is acted upon with a cleaning fluid. The stator part 20 provides linear propulsion of the pipe cleaning device 1 by means of thrust nozzles 200. The slide 4 is moved linearly through the pipe or the channel, which is indicated by the solid arrow in FIG. 3. The cleaning fluid is introduced into the nozzle module 2 via a high-pressure line connection. Optionally, stator cleaning nozzles can also be arranged on the stator part 20, which additionally deliver cleaning jets pointing radially outward from the longitudinal axis L. Through the rotating rotor part 21, the liquid jets are guided out of the cleaning nozzles 210 along the inner wall of the tube or the channel, whereby streak-free cleaning of the inner walls can be achieved. The areas on which the cleaning liquid jets strike are shown with jagged lines in FIG. 3.
    The rotationally immovable camera module 3 can record 2 video images during cleaning, spaced apart from the nozzle module, which can be adjusted by means of control electronics 33. These videos can be stored by means of memory 34 or can be transmitted to a mobile device, in particular to a smartphone, by means of transmitter 35, which can use a known radio transmission technology. The control of the camera module 3 takes place via the control electronics 33, which is carried out by means of a mobile device. For control by means of a mobile device, a so-called pairing of the mobile device and the pipe cleaning device 1 or camera module 3 must be carried out in a first step, which means the initial connection.
    As can be seen in the view of the pipe cleaning device 1 from the camera module side onto the camera module 3, the protective brackets 42 surround the nozzle module 2 and the camera module 3. The protective brackets 42 are screwed or welded to the carriage 4 or to the skid (s) 40 attached.
    In order to ensure the possibility of video recording even when there is alluvial water in the pipe or channel, more than one camera 32 can be arranged in the housing 30 at different distances from the longitudinal axis L or there can be a height adjustment device for the camera 32 or the camera module 3 are used, whereby the distance of the camera 32 or the camera module 3 to the runners 40 can be varied.
    The distance a between camera module 3 and nozzle module 2 should be made as small as possible, so that no stones or roots can jam between the rear wall of the housing 30 and the rotor part 21.
    In order to create a cleaning effect in the direction of the longitudinal axis L at the level of the camera module 3, at least one cleaning nozzle 210 can be designed in the direction toward the camera module 3.
    The wireless design of the pipe cleaning device 1 or the camera module 3 has the advantage that tangling or the destruction of a disruptive cable can be excluded during operation. The camera module 3 is supplied with sufficient energy by the internal battery 36 and can be recharged after operation.
    In order to avoid removing the camera module 3 when the battery is empty, the camera module 3 can be connected to an external charging station. This can either be operatively connected to contacts on the housing 30 of the camera module 3 or wireless battery charging, generally by means of induction, is carried out.
    The wireless data transmission of the control signals and the video data can be designed using the WLAN or Wi-Fi standard. It is provided that the data is loaded onto a tablet computer or a smartphone via the wireless data transmission or is stored in a cloud. The data would then be deleted from memory 34 to save memory space. The control of the nozzle functions, for example switching the lighting device 31 on and off, can also be carried out via the tablet computer or the smartphone, and the video recording is also controlled in this way.
