Description

Raccord pour sonde géothermique Connection for geothermal probe
L'invention concerne un raccord pour conduites utilisées dans un dispositif de sonde géothermique.The invention relates to a fitting for pipes used in a geothermal probe device.
Une sonde géothermique permet de collecter de la chaleur prélevée dans le sol terrestre. Son principe de fonctionnement est basé sur le fait que la température du sol augmente en fonction de sa profondeur. Un dispositif de sonde géothermique est essentiellement constitué d'une tête de sonde que l'on dispose au fond d'un forage et d'un système de conduites permettant d'acheminer un liquide vers la tête de sonde et de le récupérer à une température supérieure, ceci grâce à l'échange de chaleur se produisant entre le sol et le liquide en déplacement.A geothermal probe collects heat from the earth. Its operating principle is based on the fact that the temperature of the soil increases as a function of its depth. A geothermal probe device essentially consists of a probe head which is available at the bottom of a borehole and of a system of pipes making it possible to convey a liquid to the probe head and to recover it at a temperature superior, this thanks to the heat exchange occurring between the ground and the moving liquid.
Le système de conduites comporte au moins deux conduites. Il peut cependant être constitué d'un nombre de conduites plus élevé. Par exemple, on peut prévoir deux conduites d'acheminement du liquide vers la tête de sonde et une ou deux conduites de récupération du liquide. Dans le cas où il y a deux conduites d'acheminement et une conduite de récupération, la tête de sonde est configurée de manière à ce que les deux conduites d'acheminement se joignent pour former une conduite de récupération.The pipe system has at least two pipes. However, it can consist of a higher number of pipes. For example, it is possible to provide two lines for conveying the liquid to the probe head and one or two lines for recovering the liquid. In the case where there are two supply lines and a recovery line, the probe head is configured so that the two supply lines join to form a recovery line.
Lorsque pour un dispositif de sonde donné il y a plusieurs conduites d'acheminement et/ou de récupération, il est souhaitable de regrouper les conduites exerçant une même fonction en une seule conduite.When there are several routing and / or recovery lines for a given probe device, it is desirable to group the lines carrying out the same function in a single line.
A cet effet, on utilise des raccords qui peuvent par exemple avoir la forme d'un Y si il s'agit de regrouper deux conduites en une.For this purpose, fittings are used which can for example have the shape of a Y if it is a question of grouping two pipes in one.
La demande de brevet européen EP 1 036 974 A1 décrit un raccord en forme de Y pouvant être utilisé à la fois comme élément de regroupement de deux conduites ou comme tête de sonde. Pour cette deuxième application, une des extrémités du Y est obturée par un bouchon. La présente invention a pour un objet un raccord robuste et de fabrication aisée, donc économique, pouvant être utilisé comme élément de regroupement de plusieurs conduites ou comme tête de sonde.European patent application EP 1 036 974 A1 describes a Y-shaped connector which can be used both as a grouping element for two pipes or as a probe head. For this second application, one end of the Y is closed by a plug. The object of the present invention is to provide a robust fitting which is easy to manufacture and therefore economical, which can be used as a grouping element for several pipes or as a probe head.
Conformément à l'invention, ce but est atteint avec un raccord pour conduites utilisées dans un dispositif de sonde géothermique, caractérisé par le fait qu'il est constitué d'un bloc en matériau thermoplastique comprenant une première face plane et dans lequel est disposé au moins un premier passage usiné dont les deux extrémités s'ouvrent sur ladite première face plane, chacune desdites extrémités étant dimensionnée de manière à recevoir et fixer par soudage respectivement l'extrémité d'une première et d'une deuxième conduite.According to the invention, this object is achieved with a connector for pipes used in a geothermal probe device, characterized in that it consists of a block of thermoplastic material comprising a first flat face and in which is disposed at at least a first machined passage, the two ends of which open on said first flat face, each of said ends being dimensioned so as to receive and fix by welding respectively the end of a first and of a second pipe.
Il convient de relever la simplicité de fabrication du raccord selon l'invention. Le passage est usiné, par exemple au moyen de mèches, à partir d'un bloc en matériau thermoplastique tel que du polyéthylène.The simplicity of manufacture of the connector according to the invention should be noted. The passage is machined, for example by means of bits, from a block of thermoplastic material such as polyethylene.
Inversement, les raccords de l'état de la technique ne peuvent être qu'obtenus par des méthodes plus complexes et/ou onéreuses, par ex. par moulage. Dans tous les cas, leur prix de vente est relativement élevé.Conversely, prior art fittings can only be obtained by more complex and / or expensive methods, e.g. by molding. In all cases, their selling price is relatively high.
Par ailleurs, le raccord selon l'invention est plus robuste que les raccords de l'état de la technique dû au fait qu'il est constitué d'un bloc, donc ne présentant pas des parties fragiles, p.ex. des branches, à l'instar du raccord décrit dansFurthermore, the fitting according to the invention is more robust than the fittings of the prior art due to the fact that it consists of a block, therefore not having fragile parts, eg branches, like the fitting described in
EP 1 036 974 A1.EP 1 036 974 A1.
Selon un aspect avantageux de l'invention, le raccord forme une tête de sonde géothermique.According to an advantageous aspect of the invention, the connector forms a geothermal probe head.
Dans ce cas, les extrémités du passages s'ouvrent de préférence sur la face supérieure du bloc, permettant ainsi de positionner les extrémités dans le prolongement des conduites qui viennent s'y fixer.In this case, the ends of the passage preferably open on the upper face of the block, thus making it possible to position the ends in the extension of the pipes which come to be fixed there.
Selon un mode préférentiel de réalisation de l'invention, la tête de sonde comprend un deuxième passage usiné dont les deux extrémités s'ouvrent également sur ladite première face plane, chacune desdites extrémités du deuxième passage étant dimensionnée pour recevoir et fixer par soudage respectivement l'extrémité d'une troisième et d'une quatrième conduite. Dans cette configuration, on utilise de préférence deux conduites d'acheminement et deux conduites de récupération. Selon une variante, les deux passages sont séparés et selon une autre variante les deux passages communiquent entre eux. Dans ce dernier cas, la zone de communication est de préférence agrandie pour former une cavité.According to a preferred embodiment of the invention, the probe head comprises a second machined passage, the two ends of which also open on said first flat face, each of said ends of the second passage being dimensioned to receive and fix by welding respectively the end of a third and a fourth pipe. In this configuration, two delivery pipes and two recovery pipes are preferably used. According to one variant, the two passages are separated and according to another variant the two passages communicate with each other. In the latter case, the communication area is preferably enlarged to form a cavity.
Bien évidemment, la tête de sonde peut être connectée à un nombre impair et/ou supérieur de conduites. A titre d'exemple, on peut avoir deux conduites d'acheminement et une conduite de récupération, les trois conduites étant connectées à une cavité disposée dans la tête de sonde.Obviously, the probe head can be connected to an odd and / or higher number of pipes. For example, one can have two conveying lines and a recovery line, the three lines being connected to a cavity disposed in the probe head.
Selon un autre mode de réalisation de l'invention, le raccord est utilisé pour regrouper des conduites de même fonctionnalité en un nombre inférieur de conduites, par exemple pour réduire deux conduites de récupération en une conduite. Ce regroupement de conduites offrant la possibilité de réduire le nombre de conduites aboutissant ou quittant une centrale de chauffage.According to another embodiment of the invention, the connector is used to group pipes of the same functionality into a smaller number of pipes, for example to reduce two recovery pipes into one pipe. This grouping of pipes offering the possibility of reducing the number of pipes ending in or leaving a heating plant.
Dans une première variante à cet effet, le raccord comporte un deuxième passage dont la première extrémité s'ouvre sur une deuxième face du bloc qui est opposée à ladite première face plane, ladite première extrémité du deuxième passage étant dimensionnée pour recevoir et fixer par soudage l'extrémité d'une troisième conduite, les deux passages communiquant entre eux par l'intermédiaire de la deuxième extrémité du deuxième passage.In a first variant for this purpose, the connector has a second passage, the first end of which opens on a second face of the block which is opposite to said first planar face, said first end of the second passage being dimensioned to receive and fix by welding. the end of a third pipe, the two passages communicating with each other via the second end of the second passage.
Afin de ne pas trop varier la vitesse de déplacement du liquide lors du regroupement de conduites tel que décrit dans le paragraphe précédant, la section de la première extrémité du deuxième passage est supérieure à la section des extrémités du premier passage.In order not to vary the speed of movement of the liquid too much during the grouping of pipes as described in the preceding paragraph, the section of the first end of the second passage is greater than the section of the ends of the first passage.
Si l'on souhaite ne pas faire varier la vitesse, la section de la première extrémité du deuxième passage est sensiblement égale à la somme des sections des extrémités du premier passage. L'invention est décrite ci-après à l'aide de deux exemples et de références aux dessins joints, dans lesquels :If one wishes not to vary the speed, the section of the first end of the second passage is substantially equal to the sum of the sections of the ends of the first passage. The invention is described below using two examples and references to the accompanying drawings, in which:
