Abstract

The invention relates to a device for storing a liquid in a sealed flexible housing which is easy to install on the ground, the maximum capacity of which is variable, and the center of gravity of the liquid column of which can be safely raised above the ground at different heights. The device consists of a rigid supporting frame capable of being dismantled and comprising a single vertically stable strong technical pylon (1) that bears most of the weight of the liquid contained in the sealed cylindrical flexible housing by means of two ferrules horizontally secured to the latter and the heights of which are adjustable. The lower ferrule serves as a base for supporting the liquid column contained in the flexible housing and reduces the volume thereof when it is adjusted to a high position on the pylon (1). The upper ferrule is fixed and makes it possible to maintain the cylindrical shape of the flexible housing in the higher portion thereof which receives two specific half-ferrules on the inner circumference thereof. Four vertical stiffeners with small cross-sections connect the two ferrules together. The pylon (1) and stiffener assembly is connected to a base (6) comprising four legs (8), the heights of which are adjustable and which are offset relative to the horizontal cross-section of the flexible housing.

Description

Réservoir pour liquide comportant une armature rigide et une enveloppe souple reposant sur le sol, dont le centre de gravité peut être élevé au dessus du sol, dont la capacité maximale est variable. A liquid tank having a rigid frame and a flexible envelope resting on the ground, the center of gravity of which can be raised above the ground, the maximum capacity of which is variable.
La présente invention concerne un réservoir pour liquide comportant une armature rigide démontable et une enveloppe souple étanche, destiné à reposer sur le sol, et comportant une capacité maximale variable permettant de positionner la colonne de liquide à des hauteurs différentes par rapport au sol.The present invention relates to a reservoir for liquid comprising a removable rigid frame and a sealed flexible envelope, intended to rest on the ground, and having a variable maximum capacity for positioning the liquid column at different heights relative to the ground.
Le problème technique est de proposer un réservoir pour liquide contenu dans une enveloppe souple armée étanche parfaitement cylindrique, dont l'installation est aisée, dont la capacité est variable et dont la stabilité au sol quelque soit sa planéité relative et sa nature offre toute sécurité aux individus susceptible de prendre appui sur ce dernier et dont une forte emprise au vent ne peut le déstabiliser.The technical problem is to propose a reservoir for liquid contained in a perfectly cylindrical sealed waterproof flexible envelope, whose installation is easy, whose capacity is variable and whose stability on the ground whatever its relative flatness and nature offers complete security to individuals likely to rely on it and a strong hold in the wind can not destabilize.
L'état de la technique antérieure enseigne un réservoir comportant une armature rigide porteuse et une enveloppe souple dont la capacité n'est pas variable et dont le centre de gravité ne peut être élevé au dessus du sol en toute sécurité car la stabilité semble insuffisante.The state of the art teaches a tank having a rigid support frame and a flexible envelope whose capacity is not variable and whose center of gravity can not be raised above the ground safely because the stability seems insufficient.
La solution principale consiste à augmenter la surface de sustentation de l'armature rigide porteuse, dont la superficie est supérieure à la section horizontale de l'enveloppe souple, tout en conférant à l'enveloppe souple une base de soutien fixée à l'armature rigide et dont la hauteur sur celle-ci est variable.The main solution is to increase the lift surface of the rigid support frame, whose area is greater than the horizontal section of the flexible envelope, while giving the flexible envelope a support base attached to the rigid frame and whose height on it is variable.
Selon une première caractéristique l'armature rigide porteuse démontable comporte un mât technique unique résistant recevant à différents niveaux de sa longueur des orifices constituant des points d'ancrage pour diverses pièces techniques. Le mât lié à un piétement spécifique comportant quatre pieds réglables en hauteur munis de platines larges déportés par rapport à la section horizontale du réservoir, tend à le rendre stable verticalement. Ce mât est la colonne vertébrale de la structure rigide et reprend l'essentiel du poids du liquide contenu dans l'enveloppe souple à l'aide de deux viroles spécifiques fixées horizontalement sur ce dernier et réglables en hauteur .Quatre raidisseurs recevant des orifices à différent niveaux de leur longueur, constituant des points d'ancrage, positionnés sur chant par rapport la circonférence extérieure des deux viroles les lient au piétement. Les deux réglages en hauteur de la virole inférieure positionnée dans la partie basse du mât, servant de base de soutien à la colonne de liquide, confèrent à l'enveloppe souple soit sa capacité maximale de liquide, soit sa capacité minimale de liquide. La virole supérieure positionnée dans la partie haute du mât dont le réglage en hauteur est fixe et à l'aide de deux demies viroles spécifiques, sert à maintenir la forme cylindrique de l'enveloppe souple. Le diamètre intérieur des viroles est égal au diamètre extérieur de l'enveloppe souple. Les dessins annexés illustrent l'invention: La figure 1 illustre l'armature rigide lorsque la virole inférieure est réglée en position basse. La figure 2 illustre l'armature rigide lorsque la virole inférieure est réglée en position haute. La figure 3 illustre l'armature rigide et l'enveloppe souple lorsque la virole inférieure est en position basse. La figure 4 illustre l'armature rigide et l'enveloppe souple lorsque la virole inférieure est en position haute. La figure 5 illustre le piétement et les différentes pièces le composant. La figure 6 illustre les deux demi-viroles et la virole supérieure. En référence à ces dessins, le dispositif comporte un piétement (6) caractérisé par sa géométrie représentant un «V» constitué de deux tubes métalliques recevant différents orifices. Ils sont liés tous les deux à l'intérieur du «V» qu'ils constituent, à l'aide de vis, à une pièce métallique (4) dont la géométrie représente un triangle isocèle dont le sommet est tronqué, qui permet de conserver l'angle d'ouverture du «V» et limite les effets mécaniques de cisaillement de la structure.According to a first feature, the removable rigid support frame comprises a single resistant technical mast receiving, at different levels of its length, orifices constituting anchoring points for various technical parts. The mast linked to a specific base with four height-adjustable feet provided with wide plates offset from the horizontal section of the tank, tends to make it stable vertically. This mast is the backbone of the rigid structure and takes up most of the weight of the liquid contained in the flexible envelope with the aid of two specific ferrules fixed horizontally on the latter and adjustable in height. Four stiffeners receiving orifices to different levels of their length, constituting anchoring points, positioned on edge relative to the outer circumference of the two ferrules bind them to the base. The two adjustments in height of the lower ferrule positioned in the lower part of the mast, serving as support base for the liquid column, give the flexible envelope either its maximum liquid capacity or its minimum liquid capacity. The upper ferrule positioned in the upper part of the mast whose height adjustment is fixed and using two specific half ferrules, serves to maintain the cylindrical shape of the flexible envelope. The inside diameter of the ferrules is equal to the outside diameter of the flexible envelope. The accompanying drawings illustrate the invention: FIG. 1 illustrates the rigid reinforcement when the lower ferrule is set in the low position. Figure 2 illustrates the rigid armature when the lower ferrule is set high. FIG. 3 illustrates the rigid reinforcement and the flexible envelope when the lower collar is in the lower position. FIG. 4 illustrates the rigid reinforcement and the flexible envelope when the lower collar is in the high position. Figure 5 illustrates the base and the various parts composing it. Figure 6 illustrates the two half-rings and the upper shell. With reference to these drawings, the device comprises a base (6) characterized by its geometry representing a "V" consisting of two metal tubes receiving different orifices. They are both linked inside the "V" they constitute, using screws, a metal piece (4) whose geometry represents an isosceles triangle whose top is truncated, which allows to preserve the opening angle of the "V" and limits the mechanical shear effects of the structure.
La partie basse du mât (1) est fixée à l'extrémité de la pointe du «V» que forme le piétement à l'aide de pattes métalliques (5) démontables. Toutes ces parties, une fois vissées constituent un ensemble solidaire. Le piétement reçoit de part et d'autre de son «V» qu'il forme, côté extérieur au premier tiers de sa hauteur une branche métallique tabulaire (7) fixée perpendiculairement. Ces branches sont les stabilisateurs latéraux du piétement. Les extrémités des stabilisateurs ainsi que les extrémités hautes du «V» reçoivent chacune un pied réglable (8) en hauteur composé d'une platine large montée sur tige filetée à grand débattement.The lower part of the mast (1) is fixed to the end of the tip of the "V" that forms the base with metal legs (5) removable. All these parts, once screwed together constitute a solidarity. The base receives on both sides of its "V" that it forms, outside the first third of its height a tabular metal branch (7) fixed perpendicularly. These branches are the lateral stabilizers of the base. The ends of the stabilizers and the high ends of the "V" each receive an adjustable foot (8) in height consisting of a wide plate mounted on threaded rod with large clearance.
Ces pieds garantissent une position verticale du mât et optimisent la position du centre de gravité du réservoir en charge par rapport à sa base de sustentation, quelque soit la planéité relative de la surface du sol sur lequel le réservoir repose. Le déport des pieds par rapport à la section horizontale de la colonne du liquide augmente la surface de sustentation de l'armature rigide et permet d'élever le centre de gravité de la colonne de liquide contenu dans l'enveloppe souple en toute sécurité.These feet guarantee a vertical position of the mast and optimize the position of the center of gravity of the tank in load relative to its base of levitation, whatever the relative flatness of the surface of the ground on which the tank rests. The offset of the feet relative to the horizontal section of the liquid column increases the support surface of the rigid frame and allows to raise the center of gravity of the column of liquid contained in the flexible envelope safely.
Le mât technique à l'aide de ce piétement est stable verticalement et facilite donc le montage et le réglage des deux viroles sur ce dernier. La forme géométrique spécifique du piétement malgré un déport important de ses pieds par rapport à la circonférence des viroles permet d'amener plusieurs points extérieurs de ces dernières en contact avec un plan vertical pour faciliter un stockage où une utilisation spécifique du réservoir.The technical mast with this base is vertically stable and thus facilitates the mounting and adjustment of the two rings on the latter. The specific geometric shape of the base, despite a large offset of its feet relative to the circumference of the ferrules, makes it possible to bring several external points of the latter into contact with a vertical plane to facilitate storage where a specific use of the reservoir.
Les viroles reçoivent chacune plusieurs pattes métalliques de format rectangulaires recevant plusieurs orifices, fixées sur chant sur leur circonférence extérieure. Chaque virole reçoit six pattes. Deux d'entre elles sont fixées de part et d'autre de l'axe médian de la virole dont leur écartement par rapport à ce même axe permet de recevoir le mât dans son épaisseur.The ferrules each receive a plurality of rectangular metal tabs receiving several orifices, fixed on their outer circumference circumference. Each ferrule receives six legs. Two of them are fixed on either side of the median axis of the ferrule, their spacing relative to this axis allows to receive the mast in its thickness.
Les quatre autres pattes sont fixées respectivement deux à deux symétriquement par rapport à l'axe médian de la virole. Elles sont positionnées quasiment à l'aplomb des quatre branches qui forment le piétement lorsque la virole est montée sur le mât. Sur chacune de ces quatre pattes viennent se fixer à l'aide de vis verticalement des fers plats recevant des perçages à différents niveaux de leur longueur. Us permettent de relier entre elles les viroles au piétement à l'aide de pattes métalliques démontables.The other four legs are fixed respectively two to two symmetrically with respect to the median axis of the ferrule. They are positioned almost in line with the four branches that form the base when the shell is mounted on the mast. On each of these four legs are fixed by means of screws vertically flat irons receiving bores at different levels of their length. They allow to connect the ferrules to the base with the help of removable metal legs.
Les fers plats jouent le rôle de raidisseur (9) et reprennent une partie de la charge de la colonne de liquide. Ils permettent également de minimiser les déformations des deux viroles en flexion et limitent les effets de torsion de la structure métallique.The flat irons act as a stiffener (9) and take up part of the load of the liquid column. They also make it possible to minimize the deformations of the two shells in bending and limit the torsion effects of the metal structure.
L'ensemble de la structure métallique étant rigide et rendue solidaire par cinq points de fixation au piétement munis de pieds réglables en hauteur permet de réaliser une correction de l'assiette de la colonne du liquide, même avec un gros volume.The entire metal structure being rigid and secured by five attachment points to the legs provided with adjustable feet height allows for correction of the attitude of the column of the liquid, even with a large volume.
Le mât reçoit deux viroles métalliques positionnées horizontalement. L'écart entre elles correspond à la hauteur maximale de la colonne de liquide.The mast receives two metal ferrules positioned horizontally. The difference between them corresponds to the maximum height of the column of liquid.
UILLE DE REIPLACEiENT(REGLE 26) La virole inférieure (2) reçoit sur sa superficie intérieure totale une plaque de bois (10) qui repose sur des barres métalliques fixées transversalement à intervalles réguliers à l'intérieur de la virole.UILLE DE REIPLACEiENT (RULE 26) The lower shell (2) receives on its total inner surface a wooden plate (10) which rests on metal bars fixed transversely at regular intervals inside the shell.
Cette virole munie de cette plaque de bois confère à l'enveloppe souple un fond rigide et plat et reprend une grande partie du poids de la colonne du liquide. La virole inférieure à deux positions sur le mât en hauteur, une basse qui confère à l'enveloppe souple sa capacité optimale, et une haute qui diminue sa capacité, mais optimise en hauteur par rapport au sol son point de sortie de liquide pour des utilisations particulières.This shell provided with this wooden plate gives the flexible envelope a rigid and flat bottom and takes up a large part of the weight of the column of the liquid. The lower shell has two positions on the mast in height, a low which gives the flexible envelope its optimal capacity, and a high which reduces its capacity, but optimizes in height with respect to the ground its point of exit of liquid for uses special.
La virole supérieure (3) sert à maintenir la forme cylindrique de l'enveloppe souple.The upper shell (3) serves to maintain the cylindrical shape of the flexible envelope.
L'enveloppe sur sa circonférence totale supérieure extrême, comporte un bourrelet souple augmentant l'épaisseur de la bâche.The envelope on its extreme upper total circumference, comprises a flexible bead increasing the thickness of the sheet.
Deux demi-viroles (12) viennent s'appliquer sur la circonférence intérieure de l'enveloppe (11) en limite inférieure du bourrelet de façon à mettre en pression la bâche contre la circonférence intérieure de la virole supérieure. Cette pression est exercée par des vis de serrage qui passent par des orifices prévues à cet effet sur les demi-viroles, sur la bâche ainsi que sur la virole supérieure. Le bourrelet empêche l'enveloppe souple de glisser vers le bas lorsque celle-ci subit un effort de traction, en venant en buttée contre la circonférence supérieure des demies viroles.Two half-rings (12) are applied on the inner circumference of the envelope (11) at the lower limit of the bead so as to press the cover against the inner circumference of the upper shell. This pressure is exerted by clamping screws which pass through orifices provided for this purpose on the half-rings, on the sheet as well as on the upper shell. The bead prevents the flexible envelope from sliding downward when it undergoes a tensile force, abutting against the upper circumference of the half ferrules.
Les deux demi-viroles mises bout à bout ont une circonférence inférieure à la circonférence intérieure de la virole supérieure. Elles reçoivent des orifices de type oblongs assez larges horizontalement ainsi que leurs extrémités reçoivent de larges encoches horizontales de façon à optimiser et faciliter leur mise en place. Ces orifices permettent par rapport aux vis de serrage dont le point est fixe sur la virole supérieure, d'obtenir une garde de translation latérale des demies viroles suffisamment importante pour pallier aux variations d'épaisseurs de l'enveloppe souple qui augmentent ou diminuent sa circonférence intérieure et de ce fait, déplacent systématiquement sur les deux demi-viroles les points de serrage. Une mobilité latérale des demi-viroles permet de remédier à ce problème technique. Les six pattes fixées sur chant sur la circonférence extérieure de la virole supérieure reçoivent de larges lumières verticales. Elles permettent d'obtenir une translation verticale de la virole par rapport aux points de fixation qui la lient au mât ainsi qu'aux quatre raidisseurs de façon à ajuster la tension de la bâche de l'enveloppe souple.The two half-rings placed end to end have a circumference lower than the inner circumference of the upper shell. They receive oblong holes fairly wide horizontally and their ends receive large horizontal notches so as to optimize and facilitate their implementation. These orifices make it possible, with respect to the clamping screws whose point is fixed on the upper shell, to obtain a lateral translational guard of the half-rings sufficiently large to overcome the variations in thicknesses of the flexible envelope which increase or decrease its circumference. inside and thus move the clamping points systematically on both half-rings. Lateral mobility of the half-rings makes it possible to remedy this technical problem. The six legs fixed on edge on the outer circumference of the upper ring receive large vertical lights. They make it possible to obtain a vertical translation of the ferrule with respect to the attachment points which connect it to the mast as well as to the four stiffeners so as to adjust the tension of the sheet of the flexible envelope.
L'enveloppe souple comporte une bonde de fond qui permet de vider complètement son contenu. Le point de sortie de liquide d'usage le plus bas se situe environ à l/6eme de la hauteur totale de la colonne de liquide de façon à conserver une masse minimale constante qui accroît la stabilité du réservoir. L'enveloppe souple avec un même format à deux capacités de volume:The flexible envelope has a bottom drain that allows to completely empty its content. The point of lowest use liquid outlet is at approximately l / 6 th of the total height of the liquid column so as to maintain a constant minimum mass which increases the stability of the tank. The flexible envelope with the same format with two volume capacities:
- une capacité maximale lorsque la virole inférieure est en position basse sur le mât- a maximum capacity when the lower shell is in the lower position on the mast
- une capacité minimale lorsque la virole inférieure est en position haute sur le mât Les dimensions de l'enveloppe souple sont calculées de façon à ce que lorsqu'elle est installée en capacité minimale l'excédent de longueur de matière la constituant peut être replié à l'intérieur de la virole supérieure. La longueur de ce pli n'excède pas en hauteur la limite supérieure de la virole. De ce fait techniquement, il est possible d'obstruer le haut de la colonne de liquide sans gêne, à l'aide éventuellement d'un couvercle reposant sur la virole. L'armature rigide porteuse, peut également recevoir deux enveloppes distinctes dont leurs dimensions correspondent chacune, l'une à la capacité minimale de liquide, l'autre à la capacité optimale de liquide.- a minimum capacity when the lower shell is in the upper position on the mast The dimensions of the flexible envelope are calculated so that when it is installed in minimum capacity the excess length of material constituent can be folded to inside the upper ferrule. The length of this fold does not exceed in height the upper limit of the ferrule. Therefore technically, it is possible to obstruct the top of the liquid column without discomfort, possibly using a lid resting on the ferrule. The rigid carrier frame, can also receive two separate envelopes whose dimensions correspond each, one to the minimum capacity of liquid, the other to the optimum capacity of liquid.
