Abstract
Description
In Abwasserkanalsystemen, die im Boden, z.B. unter Straßen oder Wegen verlegt sind, ist es zur Zustandsüberwachung der Kanäle notwendig, das Ausmaß des Eindringens von Fremdwasser oder das Ausmaß der Versicherung von Wasser aus dem Kanal zu bewerten und dadurch Aufschluß über die Dichtheit des Kanals bzw. einzelner Kanalabschnitte sowie auch einer möglichen Gefährdung des Grundwassers durch Schmutzwasser austritt., aus dem Kanal zu erhalten. Dazu muß die Durchflussmenge im Kanal an mehreren aufeinanderfolgenden Stellen, nämlich in den einzelnen Kanalschächten, erfasst bzw. gemessen werden.In sewer systems that in Soil, e.g. under streets or are laid because of the condition monitoring of the channels, the extent of Ingress of extraneous water or the extent of insurance of water from the sewer to assess and thereby information about the tightness of the sewer or individual channel sections as well as a possible one Danger of the groundwater emerges through dirty water., from the sewer receive. To do this, the Flow rate in the channel at several successive points, namely in the individual manholes, be recorded or measured.
Das Problem bei den Durchflussmessungen liegt in der mühsamen Durchführung derselben, die bisher erfordern, in den Kanal ein Durchflussmessgerät einzubauen und nach Durchführen der Messung wieder auszubauen, was das mehrfache Einsteigen in den Schacht, das mühselige Installieren des Geräts und das anschließende Wiederausbauen des Geräts umfasst, und was für das Arbeitspersonal eine schmutzige und unangenehme Arbeit darstellt.The problem with the flow measurements lies in the tedious execution the same, which previously required the installation of a flow meter in the duct and after performing the measurement again, which is the multiple entry into the Well, the tedious Install the device and the subsequent one Remove the device includes, and what the workforce is a dirty and unpleasant job.
Als Alternative ist es auch möglich, den Fließquerschnitt des Wassers im Kanal zu bestimmen, was durch Erfassen des Fließpegels im Kanalrohr bzw. Füllungsgrades des Kanalrohrs unter Berücksichtigung von dessen bekannter Größe, nämlich Querschnittsge ometrie und Abmessungen, gemacht werden kann, und dann anhand der Fließgeschwindigkeit des Wassers die Durchflussmenge zu berechnen. Dies erfordert aber, daß die Durchflussmmenge zu berechnen. Dies erfordert wiederum, daß die Durchflussmenge in zweckmäsiger Weise gemessen wird.As an alternative, it is also possible to use the flow cross section of water in the canal to determine what is by sensing the flow level in the sewer pipe or degree of filling of the sewer pipe taking into account of its known size, namely cross-sectional geometry and dimensions, and then based on the flow rate of the water to calculate the flow rate. But this requires that the Flow rate to be calculated. This in turn requires that the flow rate in expedient Way is measured.
Aufgabe der Erfindung ist es daher, ein Gerät zur Bestimmung der Fließgeschwindigkeit in einem Kanalschacht bzw. einem Kanalrohr zu schaffen, wobei das Gerät die Messung der Fließgeschwindigkeit in einem Kanalschacht ohne Notwendigkeit des Einsteigens in den Kanalschacht ermöglichen soll.The object of the invention is therefore a device for Determination of the flow rate to create in a manhole or a sewer pipe, the Device the Flow velocity measurement in a manhole without having to enter the manhole enable should.
Diese Aufgabe wird gemäß der Erfindung ein Gerät gelöst, das ein in den Kanalschacht oder das Kanalrohr einführbares Gestell mit einem Messwertgeber in Gestalt eines an dem Gestell angeordneten, vom fließenden Wasser mit dessen Fließgeschwindigkeit bewegten Elements und Mittel zur Messwerterfassung aufweist, wobei das Gestell vorzugsweise eine in einen Kanalschacht einführbare Stange aufweist, die zur Anpassung an die Schachttiefe längenveränderlich, beispielsweise durch Ausbildung als Teleskoprohr, ausgebildet sein kann.This object is achieved according to the invention a machine solved, the one that can be inserted into the sewer shaft or sewer pipe Frame with a transmitter in the form of a on the frame arranged, from the flowing Water at its flow rate Moving element and means for data acquisition, wherein the frame preferably a rod that can be inserted into a manhole which is variable in length to adapt to the shaft depth, for example, by training as a telescopic tube can.
Dabei schlägt die Erfindung zwei alternative Lösungsvarianten für das Gerät vor, wie sie in den Ansprüchen 1 und 2 als Gerät mit einem Schwimmer als Messwertgeber bzw. als Gerät mit einem Flügelrad als Messwertgeber angegeben sind. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.The invention proposes two alternative solutions for the Device before, as in the claims 1 and 2 as a device with a float as a transmitter or as a device with a impeller are specified as sensors. Advantageous embodiments of the Invention are the subject of the dependent claims.
