EP2808448B1 - Segmental weir installation for variable, controllable damming and screen functions on relief installations - Google Patents

Description

The invention relates to a segment defense system for variable, controllable congestion and sieve functions on relief systems and derived therefrom method for installation and operation of the Segmentwehranlage. The type of segmental defense systems is well known, the technical application in the field of sewage networks and general hydraulic engineering is used for congestion activation and modulation of discharge and forward water volumes. FR 944 215 A describes a segment defense system according to the preamble of claim 1.

The needs-based relief control by axial rotational movements of the segment defense system on controllable Verschubzylinder with accumulation, sieve and emergency relief function has not yet been implemented.

The present invention has therefore set itself the task of enabling the variable, controllable storage and screening functions on relief systems by the invention of the Segmentwehranlage shown, since the additional necessary segmental arc perforation surfaces can be created inexpensively in segmental sheet and thus additional costs by the usual Installation of individual systems can be prevented, for example by connecting a rake in series with subsequent weir system.

• Fig. 1 zeigt eine 3D Darstellung einer Segmentwehranlage [20], die in einer Entlastungsanlage [2] mit beidseitigen Drehlagern [1] und verbindender Traverse [22] über zwei Verschubzylinder [23] axial drehbar montiert ist. Zu erkennen ist, daß der untere Teil des Segmentbogenbleches [9] mit seiner Segmentbogen-Staufläche [19] die gesamte Entlastungsöffnung [3] mit seiner Entlastungsöffnung-Breite [4] und Entlastungsöffnung-Höhe [5] komplett verschließt, wobei die Segmentbogen-Seitenflächen [18] auf den beidseitigen, konvex ausgebildeten Segmentbogen-Seitenauflagern [17] dichtend aufliegen.
  Die Darstellung der beiden Segmentbogen-Sehnenlängen [14] mit den zugehörigen Segmentbogen-Sehnenwinkeln α1 [15] bzw. Segmentbogen-Perforationsfläche A lassen erkennen, dass hiermit die wesentlichen Aufgaben zur Stau- und Siebfunktion der Segmentwehranlage [20] aufgezeigt werden. Die Entlastungsöffnung [3] besitzt im oberen wie unteren Bereich des Segmentbogen-Öffnungsrahmens [10] die jeweils funktional notwendigen Segmentbogen-Abstreifer-oben [7] bzw. Segmentbogen-Abstreifer-unten [8].
• Fig. 2 zeigt eine 3D Darstellung einer Segmentwehranlage [20], die nach entsprechender Absenkung mittels der beidseitig angeordneten Verschubzylinder [23] nunmehr die Siebfunktion aufzeigt, wobei die Anströmung des Abwassers durch die Fließrichtung [6] verdeutlicht wird. Erkennbar ist auch, daß die in Anspruch 2 definierten Segmentbogen-Perforationsflächen A [11]; B [12]; C [13] in Anlehnung an den Segmentbogen-Sehnenwinkeln α2 [16] funktional gedrittelt sind und wie in Anspruch 3 vermerkt, die wahlfreien, bedarfsgerechten Konturen in der Zeichnung verständlich angezeigt sind.

Possible embodiments of the invention are explained in more detail in the drawings:

• Fig. 1 shows a 3D representation of a Segmentwehranlage [20], which is axially rotatably mounted in a relief system [2] with double-sided pivot bearings [1] and connecting crosshead [22] via two Verschubzylinder [23]. It can be seen that the lower part of the segmental arcuate sheet [9] with its segmental bow storage area [19] completely closes the entire discharge opening [3] with its discharge opening width [4] and discharge opening height [5], the segment-arc side surfaces [18] lie sealingly on the bilateral, convex segment-arc side supports [17].
  The representation of the two segmental bow chord lengths [14] with the associated segment bow chord angles α1 [15] or segmental arc perforation area A indicate that the essential tasks for the accumulation and screening function of the segmental defense installation [20] are shown. The relief opening [3] has in the upper and lower region of the segmental arc opening frame [10] the respective functionally necessary segment-arc scraper-up [7] or segment-arc scraper-down [8].
• Fig. 2 shows a 3D representation of a Segmentwehranlage [20], which now shows the Siebfunktion after appropriate reduction by means of the two-sided Verschubzylinder [23], the flow of the waste water through the flow direction [6] is illustrated. It can also be seen that the segment-arc perforation surfaces A [11] defined in claim 2 ; B [12]; C [13] are functionally divided on the basis of the segmental arch chord angles α2 [16] and, as noted in claim 3 , the random, needs-based contours are clearly indicated in the drawing.
