Abstract

L'accumulateur de gaz se compose d'une paroi fixe (W) et d'un plancher fixe (B), alors que son plafond peut monter ou descendre en fonction du volume de gaz. Une feuille en cloche (S) forme une séparation mobile et étanche aux gaz entre le plafond et la paroi fixe. Afin de stabiliser et de centrer le plafond à chaque hauteur, au moins trois guides verticaux (10) répartis sur la circonférence sont installés entre la périphérie du plafond et celle de la paroi, en-dessous de la feuille en cloche, mais à l'intérieur de l'accumulateur. Chacun de ces guides comporte un court élément de guidage (11) fixé à la paroi, un rail de guidage (12), ainsi qu'un support (13) relié au plafond. Ces parties (11-13) peuvent se déplacer les unes par rapport aux autres et s'occupent du guidage vertical du plafond. Sur la gauche de la figure est représentée la position la plus basse du plafond, lorsque l'accumulateur est vide, et sur la droit, la plus haute, lorsque l'accumulateur est plein.The gas accumulator consists of a fixed wall (W) and a fixed floor (B), while its ceiling can go up or down depending on the volume of gas. A bell sheet (S) forms a mobile and gas-tight separation between the ceiling and the fixed wall. In order to stabilize and center the ceiling at each height, at least three vertical guides (10) distributed around the circumference are installed between the periphery of the ceiling and that of the wall, below the bell sheet, but at the inside the accumulator. Each of these guides comprises a short guide element (11) fixed to the wall, a guide rail (12), as well as a support (13) connected to the ceiling. These parts (11-13) can move relative to each other and take care of the vertical guidance of the ceiling. On the left of the figure is represented the lowest position of the ceiling, when the accumulator is empty, and on the right, the highest, when the accumulator is full.

Description

Gasspeicher mit variablem Nutzvolumen Gas storage with variable usable volume
Die Erfindung bezieht sich auf einen Gasspeicher mit variablem Nutzvolumen, fester Seitenwand und einer zwischen der Seitenwand und der Gasspeicherdecke angeordneten Stulpfolie.The invention relates to a gas storage tank with a variable usable volume, a fixed side wall and a cuff foil arranged between the side wall and the gas storage ceiling.
Gasspeicher dieser Art sind bekannt.Gas stores of this type are known.
Zur Aufrechterhaltung der Funktionsfähigkeit und Betriebssicherheit der Stulpfolie sind Vorrichtungen zum Stabilisieren und Zentrieren der Decke erforderlich. Soll im Speicher auch ein gewisser Druck aufrecht erhalten werden, stellen sich zusätzliche Probleme aus Aufbringung, Verteilung, Lastübertragung und Lagesicherung der Belastung. Bei grösserem Durchmesser des Gasspeichers werden damit aufwendige Konstruktionen nötig.Devices to stabilize and center the ceiling are required to maintain the functionality and operational safety of the cuff. If a certain pressure is also to be maintained in the store, additional problems arise from application, distribution, load transfer and securing the position of the load. With a larger diameter of the gas storage, complex constructions are necessary.
Bekannte Ausführungen verwenden zum Beispiel eine zentrale, am Boden oder an einer soliden Ueberdeckung befestigte, vertikale Führungssäulen, oder Seilführungen, die durch ein auf der Decke angeordnetes Oelbad gasdicht vom Gasraum nach aussen geführt werden. Die Erfindung stellt sich zur Aufgabe, eine möglichst einfache und doch zuverlässige Führung für eine solche Gasspeicherdecke anzugeben.Known designs use, for example, a central, vertical guide pillar attached to the floor or to a solid cover, or cable guides which are guided gas-tight from the gas space to the outside by an oil bath arranged on the ceiling. The invention has for its object to provide a simple and yet reliable guidance for such a gas storage ceiling.
Zusätzlich soll sie für alle Behälterbauweisen ohne baulichen Mehraufwand anwendbar sein.In addition, it should be applicable to all container designs without additional constructional effort.
Die Erfindung löst diese Aufgabe mit einer Führung, die sich auszeichnet durch die im Patentanspruch 1 angegebenen besonderen Merkmale.The invention solves this problem with a guide, which is characterized by the special features specified in claim 1.
In der beigefügten Zeichnung ist ein Ausfuhrungsbeispiel des Erfindungsgegenstandes vereinfacht dargestellt, und zwar zeigen:An exemplary embodiment of the subject matter of the invention is shown in simplified form in the accompanying drawing, namely:
Figur 1 einen Vertikalschnitt durch einen Gasspeicher und Figur 2 einen Horizontalschnitt längs der Linie II -II in Figur 1; Figur 3 einen Vertikalschnitt wie bei Figur 1 in dem die Führungen in grösserem Masstab, mehr im1 shows a vertical section through a gas storage and 2 shows a horizontal section along the line II -II in Figure 1; Figure 3 is a vertical section as in Figure 1 in which the guides on a larger scale, more in
Detail ersichtlich sind; Figur 4 einen Schnitt längs der Linie IV - IV inDetail can be seen; 4 shows a section along the line IV - IV in
Figur 3 in noch grösserem Masstab, und Figur 5 einen Schnitt längs rder Linie V - V in3 in an even larger scale, and FIG. 5 shows a section along the line V - V in
Figur 3, in noch grösserem Masstab. Die Figuren 1 und 2 zeigen in vereinfachter Darstellung einen Gasspeicher mit einer kreiszylindrischen, starren Wand W, Boden B, und einer zwischen der Wand und der Decke D angeordneten Stulpfolie S.Figure 3, on an even larger scale. Figures 1 and 2 show a simplified representation of a gas storage device with a circular cylindrical, rigid wall W, floor B, and a cuff film S arranged between the wall and the ceiling D.
Beim dargestellten Gasspeicher besteht die Decke aus einem starren, die Peripherie der Decke bildenden, mit einer gasdichten Folie F überspannten Ring R. Der Speicher ist durch ein Dach abgedeckt und unten mit einem Füll-Ablassventil versehen.In the gas storage tank shown, the ceiling consists of a rigid ring R, which forms the periphery of the ceiling and is covered with a gas-tight film F. The storage tank is covered by a roof and is provided at the bottom with a filling drain valve.
Innerhalb des Speicherraumes, zwischen der festen Seitenwand W und der Decke R,D sind drei unabhängig voneinander arbeitende, generell mit 10 bezeichnete Vertikalführungen dargestellt. Diese umfassen drei Hauptbestandteile, nämlich ein kurzeß an der Wand W befestiges Führungselement 11, eine Führungsschiene 12 und einen mit der Decke R,D verbundenen Halter 13. Die Führungsschiene 12 ist verschiebbar am Führungselement 11 geführt, und der Halter 13 ist seinerseits an der Schiene 12 verschiebbar geführt.Within the storage space, between the fixed side wall W and the ceiling R, D, three independent vertical guides, generally designated 10, are shown. These comprise three main components, namely a short guide element 11 fastened to the wall W, a guide rail 12 and a holder 13 connected to the ceiling R, D. The guide rail 12 is slidably guided on the guide element 11 and the holder 13 is in turn on the rail 12 slidably guided.
In Figur 1 ist oben rechts die Relativlage dieser Elemente bei gefülltem Gasspeicher, unten links bei entleertem Speicher dargestellt. Bereits jetzt sei vermerkt, dass die Decke auch aus einer starren, gegebenenfalls durch Rippen versteiften Platte bestehen kann, ohne dass dies die Konstruktion der Vertikalführungen beeinflusst. Die Figur 3 zeigt die Vertikalführung mehr im Detail. Damit die Führungsschiene 12 und der Halter 13 leicht verschiebbar sind, ist sowohl das Führungselement 11, als auch der Halter 13 mit Rollenpaaren 14 ausgerüstet, die in Bahnen der Führungsschiene 12 geführt sind. Die Führungsschiene hat ein doppelt-kastenförmiges Querschnittsprofil, wie in Figur 4 ersichtlich.In FIG. 1, the relative position of these elements is shown at the top right when the gas reservoir is full, and at the bottom left when the reservoir is empty. It should already be noted that the ceiling can also consist of a rigid plate, possibly stiffened by ribs, without this affecting the construction of the vertical guides. Figure 3 shows the vertical guide in more detail. So that the guide rail 12 and the holder 13 are easily displaceable, both the guide element 11 and the holder 13 are equipped with pairs of rollers 14 which are guided in paths of the guide rail 12. The guide rail has a double box-shaped cross-sectional profile, as can be seen in FIG. 4.
Zwischen Rolle und Führungsbahnen ist ein kleiner Spielraum vorgesehen, damit die Rollen jeweils nur auf einerA small margin is provided between the roller and guideways so that the rollers are only on one
Seite der Führungsbahn aufliegen und in jeder Stellung ungehindert abrollen können.Can rest on the side of the guideway and roll freely in any position.
Durch im Profil vorgesehene, einander gegenüberliegende Schlitze, ragen das Führungselement 11 und der Halter 13 ein Stück weit in die Schiene hinein. An diesem in die Schiene ragenden Teil sind die Rollenpaare 14 befestigt. Die Anordnung von zwei Rollenpaaren je Führungselement und die Biegesteifigkeit der Führungsschiene verhindern eine Schrägstellung der Decke.Through slots provided opposite each other in the profile, the guide element 11 and the holder 13 protrude a bit into the rail. The roller pairs 14 are fastened to this part which projects into the rail. The arrangement of two pairs of rollers per guide element and the bending stiffness of the guide rail prevent the ceiling from sloping.
Mittels in der Führungsschiene verlaufenden Seilzügen 20,21 ist eine Mitnehmervorrichtung geschaffen, welche in jeder Lage der Decke die jeweilige Relativlage der Teile der Vertikalführung steuert. Dazu sind oben und unten an der Führungsschiene 12 Seilrollen 22 angebracht. Seil 20 ist an der Unterseite des Halters 13 befestigt und führt über die untere Rolle 22 zur unteren Seite des Führungselementes 11, wo es wieder befestigt ist.. Auf ähnliche Weise verbindet Seil 21 die obere Seite des Halters 13 mit der oberen Seite des Elementes 11, wobei es über die obere Rolle 22 geführt ist.A driver device is created by means of cables 20, 21 running in the guide rail, which controls the relative position of the parts of the vertical guide in each position of the ceiling. For this purpose, 12 pulleys 22 are attached to the top and bottom of the guide rail. Rope 20 is attached to the underside of the holder 13 and leads via the lower roller 22 to the lower side of the guide element 11, where it is reattached. Similarly, rope 21 connects the upper side of the holder 13 to the upper side of the element 11 , wherein it is guided over the upper roller 22.
Die beiden Seile bilden so eine Art Zwangssteuerung, die eine Sicherung gegen Verletzung der Stulpfolie im Betrieb darstellt. Würde beim Entleeren des Gasspeichers die Führungsschiene 12 in der in Figur 3 links dargestellten, höchsten Lage verharren, bestände die Gefahr, dass sie die Stulpfolie verletzt.The two ropes form a kind of positive control, which is a safeguard against injury to the cuff foil during operation. If the guide rail 12 remained in the highest position shown on the left in FIG. 3 when the gas storage device was emptied, there would be a risk that it would damage the forend foil.
Als zusätzliche Sicherung gegen eine Verletzung der Stulpfolie sind seitlich, oben auf der Führungsschiene 12 breite Rollen 23 angebracht.As an additional safeguard against injury to the cuff film, 12 wide rollers 23 are mounted on the side, at the top of the guide rail.
Bei der Montage der Vertikalführungen wird man dafür sorgen, dass sie so genau wie möglich vertikal ausgerichtet sind. Der Idealzustand lässt sich nur mit grossein konstruktivem Aufwand und umständlichen Montagearbeiten erreichen. Da zudem mit Ungenau!gkeiten beim Bau (Masstoleranzen) und Betrieb (Dehnungen) der Behälterwand gerechnet werden muss, besteht die Gefahr, dass sich die Führungen verklemmen, da sie ja durch die Decke miteinander verbunden sind. Aus diesem Grund ist die Decke nicht fest, sondern begrenzt horizontal verschiebbar mit den Haltern 13 verbunden.When installing the vertical guides, care will be taken to ensure that they are aligned as precisely as possible. The ideal condition can only be achieved with great design effort and laborious assembly work. Since inaccuracies in the construction (dimensional tolerances) and operation (expansion) of the tank wall must also be expected, there is a risk that the guides jam, since they are connected to each other by the ceiling. For this reason, the ceiling is not fixed, but is connected to the holders 13 so that it can be moved horizontally to a limited extent.
In Figur 5 ist die konstruktive Ausführung dieser Verbindung dargestellt. Der Halter 13 ist dazu mit Rollenpaaren 14 versehen und die Decke ist torsionsfest mit kurzen horizontalen Schienenabschnitten 30 verbunden, die ein kastenförmiges Querschnittsprofil aufweisen. Der Halter 13 ragt durch einen im Profil angebrachten Schlitz ein stückweit hinein und das Gewicht der Decke ruht auf den Rollenpaaren 14.FIG. 5 shows the construction of this connection. The holder 13 is provided with pairs of rollers 14 and the ceiling is torsionally connected to short horizontal rail sections 30 which have a box-shaped cross-sectional profile. The holder 13 protrudes a little way through a slot in the profile and the weight of the blanket rests on the pairs of rollers 14.
Die Führungsschiene 12 ist unten und oben teilweise durch Platten 15 geschlossen und diese bilden zugleich Anschläge am Führungselement 11, für die oberste und unterste Lage der Vertikalführung 10.The guide rail 12 is partially closed at the top and bottom by plates 15, which at the same time form stops on the guide element 11, for the top and bottom position of the vertical guide 10.
Wie in Figur 3 angedeutet, beträgt der Hub der Führungsschiene 12 genau die Hälfte des Hubes H der Decke R, F. Die Anordnung der Führungskonstruktion im Gasraum setzt eine wartungs- und korrosionsfreie Konstruktion voraus. Dies wird durch die Verwendung von rostfreiem Stahl, beziehungsweise Kunststoff für alle mechanisch beanspruchten Teile gewährleistet.As indicated in Figure 3, the stroke of the guide rail 12 is exactly half the stroke H of the ceiling R, F. The arrangement of the guide construction in the gas space requires a maintenance and corrosion-free construction. This is guaranteed by the use of stainless steel or plastic for all mechanically stressed parts.
Neben dem, zur Erläuterung des Erfindungsgegenstandes dargestellten Beispiel kommen auch andere Ausführungsformen in Frage. So können anstelle der Rollen beispielsweise auch Gleitlager- oder Kugelrollenkonstruktionen mit entsprechendangepassten Führungsschienen verwendet werden. In addition to the example shown to explain the subject matter of the invention, other embodiments are also possible. For example, slide bearing or ball roller constructions with appropriately adapted guide rails can be used instead of the rollers.
