Beschreibung Technisches Gebiet [0001] Die vorliegende Erfindung beschreibt ein Hochdruckreinigungssystem zur Reinigung von Rohren, Kanälen und Flächen mit einem Druckmedium, umfassend ein Steuergerät, welches mit einer Flüssigkeitspumpe verbindbar ist, wobei das Druckmedium mittels Flüssigkeitspumpe vom Steuergerät gesteuert und geregelt durch einen Hochdruckreinigungsschlauch und eine damit verbundene Hochdruckreinigungsdüse abgebbar ist, sowie ein Reinigungsverfahren zur Reinigung von Rohren, Kanälen und Flächen mit einem Druckmedium, umfassend ein Steuergerät, welches mit einer Flüssigkeitspumpe verbindbar ist, wobei das Druckmedium mittels Flüssigkeitspumpe vom Steuergerät gesteuert und geregelt durch einen Hochdruckreinigungsschlauch und ein damit verbundenes Hochdruckreinigungsgerät abgebbar ist und ein Hochdruckreinigungsgerät zur Reinigung von Rohren, Kanälen und Flächen mit einem Druckmedium.Description Technical Field The present invention describes a high-pressure cleaning system for cleaning pipes, channels and surfaces with a pressure medium, comprising a control unit, which is connectable to a liquid pump, wherein the pressure medium is controlled by the control unit by means of a liquid pump and controlled by a high-pressure cleaning hose and a associated high-pressure cleaning nozzle can be dispensed, and a cleaning method for cleaning pipes, channels and surfaces with a pressure medium, comprising a control unit which is connectable to a liquid pump, wherein the pressure medium controlled by a liquid pump from the controller and controlled by a high-pressure cleaning hose and a high-pressure cleaning device connected thereto can be dispensed and a high-pressure cleaning device for cleaning pipes, channels and surfaces with a pressure medium.

Stand der Technik [0002] Hochdruckreinigungsdüsen werden unter Verwendung eines Druckmediums zur Reinigung von Rohren, Kanälen und Flächen in Industrieanlagen, Kanalinstallationen der öffentlichen Hand sowie in privaten Bereichen eingesetzt. Hochdruckreinigungsdüsen stellen mittels Druckmedium, insbesondere mit Wasser angetriebene Reinigungswerkzeuge dar, welche fast universell einsetzbar sind.Background Art High-pressure cleaning nozzles are used by using a pressure medium for cleaning pipes, channels and surfaces in industrial plants, public-sector sewers and private areas. High-pressure cleaning nozzles represent by means of pressure medium, in particular with water driven cleaning tools, which are almost universally applicable.

[0003] Je nach Verwendungszweck sind die Hochdruckreinigungsdüsen unterschiedlich gestaltet, was zu unterschiedlichen erreichbaren Reinigungs- und Schwemmleistungen führt und bilden einen Teil eines Hochdruckreinigungssystems. Bei geeigneter Wahl der Hochdruckreinigungsdüsen können Schlammablagerungen, Kalkablagerungen, Schotter oder Geröll und sogar Verwurzelungen aus Rohren, Kanälen und von Flächen entfernt werden. Es sind Kanalreinigungs- oder Spitzdüsen sowie Granatbomben als Hochdruckreinigungsdüsen kommerziell erhältlich.Depending on the intended use, the high-pressure cleaning nozzles are designed differently, resulting in different achievable cleaning and alluvial services and form part of a high-pressure cleaning system. With a suitable choice of high-pressure cleaning nozzles, sludge deposits, limescale deposits, gravel or boulders and even rootings from pipes, channels and surfaces can be removed. There are Kanalreinigungs- or pointed nozzles and grenade bombs as high-pressure cleaning nozzles commercially available.

[0004] Vor Ort wird die jeweils eine, für das zu reinigende Rohr geeignete Hochdruckreinigungsdüse gewählt, mit einem Hochdruckreinigungsschlauch verbunden und in das Rohr eingelassen. Durch manuelle Eingabe gewünschter Reinigungsparameter an einem Steuergerät durch einen Benutzer des Hochdruckreinigungssystems, wird der Hochdruckreinigungsschlauch und die daran befestigte Hochdruckreinigungsdüse mittels einer geeigneten Flüssigkeitspumpe mit der Reinigungsflüssigkeit unter wählbaren Reinigungsparametern von Drücken zwischen einigen bis mehreren hundert Bar und Volumenströmen bzw. Durchflussmengen zwischen einigen bis einigen hundert Litern pro Minute beaufschlagt. Das Steuergerät steuert die Flüssigkeitspumpe während des Reinigungsvorganges auf die programmierten Reinigungsparameter.On site, each one is selected for the pipe to be cleaned suitable high-pressure cleaning nozzle, connected to a high-pressure cleaning hose and inserted into the pipe. By manually inputting desired cleaning parameters to a control unit by a user of the high-pressure cleaning system, the high-pressure cleaning hose and the high-pressure cleaning nozzle attached thereto by means of a suitable liquid pump with the cleaning liquid under selectable cleaning parameters of pressures between several to several hundred bar and flow rates between several to a few hundred Liters per minute. The control unit controls the liquid pump during the cleaning process to the programmed cleaning parameters.

[0005] Das Ziel ist die Erreichung einer effizienten, ökonomischen und ökologischen Rohr-, Kanal- oder Flächenreinigung, was nur erreichbar ist, wenn die richtige Hochdruckreinigungsdüse dem zu lösenden Reinigungsproblem entsprechend gewählt wird und die optimalen Reinigungsparameter am Steuergerät eingestellt werden. Nur dann kann eine optimale Reinigungswirkung erzielt werden und das ressourcenschonend. Sollte einer der Reinigungsparameter aus Druck und Volumenstrom nicht zur gewählten Hochdruckreinigungsdüse passen, wird mehr Energie und/oder mehr Druckmedium verbraucht als nötig, wobei auch die Reinigungswirkung leidet. Wenn ein zu hoher Druck des Druckmediums auf die gewählte Hochdruckreinigungsdüse wirkt, dann zerstäuben die austretenden Reinigungsstrahlen sehr stark und der Reinigungseffekt ist geschwächt bis nicht mehr vorhanden.The goal is to achieve an efficient, economical and ecological pipe, sewer or surface cleaning, which can only be achieved if the right high-pressure cleaning nozzle is chosen according to the cleaning problem to be solved and the optimum cleaning parameters are set on the control unit. Only then can an optimal cleaning effect be achieved and conserve resources. Should one of the cleaning parameters of pressure and flow rate not match the selected high-pressure cleaning nozzle, more energy and / or more pressure medium is consumed than necessary, which also suffers the cleaning effect. If too much pressure of the pressure medium acts on the selected high-pressure cleaning nozzle, then the exiting cleaning jets spray very heavily and the cleaning effect is weakened or no longer present.

[0006] Es ist damit heute nicht gesichert, dass bei der Durchführung von Reinigungsarbeiten die geeigneten Reinigungsparameter entsprechend der gewählten Hochdruckreinigungsdüse am Steuergerät eingestellt werden und damit die Flüssigkeitspumpe korrekt, auf die Hochdruckreinigungsdüse geregelt, arbeitet.It is therefore not guaranteed today that when performing cleaning the appropriate cleaning parameters are set according to the selected high-pressure cleaning nozzle on the control unit and thus the liquid pump correctly regulated to the high-pressure cleaning nozzle works.

Darstellung der Erfindung [0007] Die vorliegende Erfindung hat sich zur Aufgabe gestellt, ein Hochdruckreinigungssystem zu schaffen, welches automatisiert entsprechend der gewählten Hochdruckreinigungsdüse arbeitet, wodurch eine reproduzierbare und betreffend Ökonomie und Ökologie optimierte Kanalreinigung, in Form einer optimierten Hydro- bzw. hydromechanischen Reinigung, ermöglicht wird.SUMMARY OF THE INVENTION It is an object of the present invention to provide a high-pressure cleaning system which operates automatically in accordance with the selected high-pressure cleaning nozzle, thereby achieving reproducible and economy-optimized drainage, in the form of optimized hydro- or hydromechanical cleaning, is possible.

[0008] Eine weitere Aufgabe der Erfindung ist die Bereitstellung eines Reinigungsverfahrens, welches die Nutzung von ökologisch und ökonomisch optimierten Reinigungsparametern garantiert.Another object of the invention is to provide a cleaning process which guarantees the use of ecologically and economically optimized cleaning parameters.

[0009] Zur Durchführung des Reinigungsverfahrens und als Teil des Hochdruckreinigungssystems wird ein spezielles Hochdruckreinigungsgerät, wie in Anspruch 10 beansprucht, eingesetzt.To carry out the cleaning process and as part of the high-pressure cleaning system, a special high-pressure cleaning device, as claimed in claim 10 is used.

Beschreibung [0010] Hier wird ein Hochdruckreinigungssystem zur Reinigung von Rohren, Kanälen und Flächen mit einem Druckmedium beschrieben. Das Hochdruckreinigungssystem umfasst ein Steuergerät, welches mit einer Flüssigkeitspumpe, bevorzugt in Form einer Höchstdruckpumpe, verbindbar ist, wobei das Druckmedium mittels Flüssigkeitspumpe vom Steuergerät gesteuert und geregelt durch einen Hochdruckreinigungsschlauch und ein damit verbundenes Hochdruckreinigungsgerät,Description A high-pressure cleaning system for cleaning pipes, channels and surfaces with a pressure medium is described here. The high-pressure cleaning system comprises a control unit which can be connected to a liquid pump, preferably in the form of a high-pressure pump, wherein the pressure medium is controlled by the control unit by means of a liquid pump and regulated by a high-pressure cleaning hose and a high-pressure cleaning device connected thereto,

Claims

here in the form of a high-pressure cleaning nozzle, can be issued. The high-pressure cleaning nozzle is a preferably water-driven cleaning tool for cleaning the inner surfaces of pipes, channels and surfaces. So that a user of the high-pressure cleaning system does not enter any unsuitable cleaning parameters on the control unit for performing the cleaning when the high-pressure cleaning nozzle is selected, the high-pressure cleaning nozzle has a transponder on. This transponder is permanently attached to or within a portion of the high pressure cleaning nozzle. In the transponder an identification code is deposited, which is assigned to each high-pressure cleaning nozzle. When the high pressure cleaning nozzle is selected, a reader operatively connected to the controller can recognize or identify the high pressure cleaning nozzle. The identification of the high-pressure cleaning nozzle can be carried out before or after the connection of the high-pressure cleaning nozzle with the high-pressure cleaning hose. Depending on the selected transponder, the reading of the transponder can take place even after the introduction of the high-pressure cleaning hose into a pipe or a channel to be cleaned or when positioning it on a surface. It transponders are used, which can be detected by the reader without contact. For this purpose, transponders are suitable whose data contents can be interrogated and written by electromagnetic or magnetic signals. After reading the identification code of the transponder by the reader, the identity of the high-pressure cleaning nozzle is transmitted to the control unit. The control unit has a data memory in which different high-pressure cleaning nozzles are assigned corresponding optimal cleaning parameters. After the cleaning parameters matching the selected and installed high-pressure cleaning nozzle have been determined, the liquid pump with these cleaning parameters is operated by the control unit during the cleaning process. The user of the high-pressure cleaning system can thus operate the cleaning method automatically only with cleaning parameters suitable for the high-pressure cleaning nozzle. A misadjustment of too high or too low pressure or an unsuitable flow rate at the control unit is not possible. The control unit determines by read by means of a reader and identification of the high pressure cleaning nozzle used the optimal cleaning parameters independently, with misadjustments are prevented by the user. As a transponder RFID transponder or RFID tags are preferably used here. Such RFID tags can be passive, no power supply or active, be designed with power supply and operate in different frequency ranges from long wave to shortwave to UHF or SHF (Super High Frequency). The RFID tag receives signals via an antenna and a receive and transmit circuit and can also send them again. Since here the high-pressure cleaning nozzles with RFID transponders do not have large distances to the reading device, it is also possible to use inductively coupled RFID transponders which can be described and read out by means of a magnetic alternating field. If the RFID tag is made passive, then the energy of the incoming signals is used for the power supply. The identification code is stored in an internal memory of the RFID tag and can be read out accordingly, whereby a unique identification of each high-pressure cleaning nozzle based on the RFID tag used is possible. The preferably integrally executed RFID tag can be attached by suitable means during the preparation of the high-pressure cleaning nozzle, after equipping the outlet nozzles or after completion of the high-pressure cleaning nozzle on or in the body of the nozzle. The description of the RFID tag and thus the permanent storage of the identification code can be carried out before connection or after connection of the RFID tag with the high-pressure cleaning nozzle by means of writing instrument or read / write device. After the completion of the high-pressure cleaning nozzle or storing special information on the high-pressure cleaning nozzle, the nozzle can later be clearly identified by the identification code from the high-pressure cleaning nozzle, automatically identified by the reader on the control unit. There are temperature-insensitive RFID transponders available that are fastened to or in a portion of the high-pressure cleaning nozzle and are sufficiently stable so that the RFID transponder during manufacture of the high-pressure cleaning nozzle can be fastened and also survives the cleaning operations harmless. Suitable high-pressure cleaning nozzles which can be connected to the RFID tag are commercially available sewer cleaning nozzles or pointed nozzles as well as grenade bombs. By attaching the RFID tag to the high pressure cleaning nozzle, an identification of a stolen high pressure cleaning nozzle can be made in addition. Based on the RFID tag can be determined whether the high pressure cleaning nozzle has been stolen, or who originally heard this, as well as this information can also be stored in the internal memory of the RFID tag. claims
