Description

Dispositif d'entraînement électrique pour arroseur Electric drive device for sprinkler
La présente invention concerne un dispositif d'entraînement électrique à alimentation externe pour dispositif d'arrosage, un dispositif d'arrosage comprenant ledit dispositif d'entraînement ainsi qu'un arroseur comprenant ledit dispositif d'arrosage.The present invention relates to an external power supply electric drive device for a watering device, a watering device comprising said drive device and a sprinkler comprising said watering device.
Dans le domaine des arroseurs on connaît depuis longtemps les arroseurs, enterrés ou aériens, qui transforment l'énergie du jet d'eau en énergie mécanique utilisée pour disperser l'eau d'arrosage.In the field of sprinklers we have long known sprinklers, buried or air, which convert the energy of the water jet mechanical energy used to disperse the water spray.
Différents mécanismes ont été élaborés dans l'art antérieur. On citera par exemple les arroseurs se trouvant enterrés en période de reposDifferent mechanisms have been developed in the prior art. For example, sprinklers that are buried during rest periods
(c'est-à-dire en période de non arrosage) et dont au moins une partie, particulièrement la buse d'arrosage se déploie hors terre lorsque l'arrosage est déclenché. Ces mécanismes utilisent donc la pression de l'eau d'une part pour déplacer verticalement un piston porteur d'un porte-buse au travers desquels l'eau circule, et d'autre part au travers d'un mécanisme mécanique particulier, parfois intégré dans le piston, pour induire un mouvement rotatif circulaire tout au moins à la buse d'arrosage.(That is, during no watering) and at least a portion of which, especially the watering nozzle, deploys above ground when watering is triggered. These mechanisms therefore use the pressure of water on the one hand to vertically move a piston carrying a nozzle holder through which the water circulates, and secondly through a particular mechanical mechanism, sometimes integrated in the piston, to induce circular rotary motion at least to the watering nozzle.
On citera par exemple les arroseurs comportant une cuillère qui pivote sur un axe pour alternativement atteindre le jet d'eau et en être écarté par l'impact de l'eau. Ce mouvement de va et vient est utilisé pour déplacer la direction du jet d'eau latéralement dans un premier sens de rotation.Examples include sprinklers with a spoon that pivots on an axis to alternately reach the water jet and be separated by the impact of water. This movement back and forth is used to move the direction of the water jet laterally in a first direction of rotation.
Bien qu'efficaces, ces dispositifs nécessitent une pression d'eau relativement élevée pour pouvoir fonctionner correctement. En particulier lorsque la pression d'eau devient insuffisante le mécanisme visant à entraîner la rotation de l'arroseur ne peut plus fonctionner, l'arroseur est alors stoppé en une position aléatoire et l'eau n'est déversée que dans une seule zone du terrain à arroser ce qui peut avoir de fâcheuses conséquences.Although effective, these devices require a relatively high water pressure to function properly. Especially when the water pressure becomes insufficient the mechanism to cause the rotation of the sprinkler can no longer work, the sprinkler is then stopped in a random position and the water is discharged in only one zone of the sprinkler. ground to water which can have unfortunate consequences.
De plus, le principe de fonctionnement est tel que la conception intègre des éléments fortement sollicités mécaniquement et donc assujettis à des usures prématurées comme les freins, les bras et les roulements ou paliers qui les composent. D'autre part, la conception est telle que la vitesse de rotation est directement liée à la taille de la buse utilisée et à la pression disponible sur le réseau entraînant des difficultés pour ajuster finement la vitesse de l'arroseur. Il en est de même pour la fréquence de hachage du jet par le mouvement de bras.In addition, the operating principle is such that the design incorporates elements highly mechanically stressed and thus subject to premature wear such as brakes, arms and bearings or bearings that compose them. On the other hand, the design is such that the rotational speed is directly related to the size of the nozzle used and the pressure available on the network causing difficulties to finely adjust the speed of the sprinkler. It is the same for the frequency of hashing of the jet by the movement of arms.
Pour palier ces inconvénients des arroseurs électriques ont déjà été proposés. Par dans US 6,336,596, il est proposé un arroseur enterré comportant un moteur et un dispositif de réduction permettant d'assurer la rotation de la buse et du porte buse. On note cependant que dans le dispositif présenté, le moteur et le réducteur sont placés à l'intérieur du piston mobile verticalement dont ils épousent les mouvements verticaux induits par la pression de l'eau sur une membrane disposée en partie inférieure. Ce dispositif résout une partie des inconvénients décrits précédemment mais en créé d'autres. En effet le moteur étant électrique le dispositif à besoin d'une alimentation. Celle-ci se présente sous la forme d'un câble électrique qui va donc suivre les mouvements verticaux du moteur donc en fait les mouvements verticaux du piston mobile. Ce mouvement de va-et-vient vertical appliqué au câble électrique d'une façon répétée peut entraîner une durée de vie plus courte voire un dysfonctionnement total de l'arroseur. Le câble peut se sectionner de lui-même par les flexions répétées ou être sectionné par un coincement entre deux pièces dont une est mobile et l'autre fixe.To overcome these disadvantages of electric sprinklers have already been proposed. In US 6,336,596, there is provided a buried sprinkler comprising a motor and a reduction device for rotating the nozzle and the nozzle holder. We note, however, that in the device shown, the motor and the reducer are placed inside the vertically movable piston which they marry the vertical movements induced by the pressure of water on a membrane disposed in the lower part. This device solves some of the disadvantages described above but creates others. Indeed the motor being electric the device needs a power supply. This is in the form of an electric cable that will follow the vertical movements of the engine so in fact the vertical movements of the movable piston. This vertical reciprocating motion applied to the electrical cable in a repeated manner may result in a shorter service life or even total malfunction of the sprinkler. The cable can cut itself by repeated bending or be cut by a wedge between two parts, one is movable and the other fixed.
C'est un des objectifs de la présente invention que de pallier les inconvénients ci- dessus exposés.It is one of the objectives of the present invention to overcome the disadvantages described above.
La conception de la présente invention présente la particularité de séparer de façon indépendante la partie motrice (mouvement de rotation) de la partie élévatrice qui génère le mouvement vertical. Une seconde particularité de cette conception permet au dispositif d'entraînement d'être fixe par rapport au sol et de n'avoir que son arbre de sortie en rotation. Cet arbre de sortie du dispositif d'entraînement est creux de façon à laisser passer l'eau sous pression. Au dessus et sur cet arbre de sortie se fixe un plateau intermédiaire lui même relié à une chambre dans laquelle coulisse sous l'effet de la pression un piston également creux en son centre. Le mouvement de ce piston créé le mouvement vertical.The design of the present invention has the particularity of separating independently the driving part (rotational movement) of the elevating part which generates the vertical movement. A second feature of this design allows the drive device to be fixed relative to the ground and to have only its output shaft in rotation. This output shaft of the drive device is hollow so as to let the water under pressure. Above and on this output shaft is fixed an intermediate plate itself connected to a chamber in which slides under the effect of pressure a piston also hollow in its center. The movement of this piston creates the vertical movement.
Les avantages sont les suivants :The advantages are:
- Le dispositif d'entraînement est fixe et de ce fait son câble d'alimentation électrique l'est aussi évitant tout risque de rupture précoce lors des mouvements avec des conceptions classiques ;- The drive device is fixed and therefore its power cable is also avoiding any risk of early breakage during movements with conventional designs;
Le nombre de composants à soulever par le piston est beaucoup plus limité dans cette conception que lorsque la partie motrice est intégrée au piston ou située au dessus du piston donc le poids à soulever est moindre. De ce fait, le piston réagit à une pression d'eau plus basse ce qui est un avantage ; les pièces en mouvement vertical sont assujetties à des usures de fonctionnement fréquentes. Grâce à la conception selon l'invention, ces pièces sont immédiatement accessibles ce qui facilite grandement la maintenance contrairement à un arroseur de conception classique. Les dispositifs d'arrosage décrits précédemment comportent en général et sans limitation, une chambre piston reposant sur un fond et comportant un piston creux, mobile dans la partie interne de la chambre piston, ledit piston traversant la partie supérieure de ladite chambre piston est venant au droit d'un orifice ménagé dans le fond au travers duquel l'eau circule, l'étanchéité de l'ensemble étant assuré par des moyens adéquats. Le piston mobile comprend à sa partie supérieure une tête d'arrosage, éventuellement solidaire dudit piston, à tout le moins dans sa continuité, et comportant au moins une buse assurant Ia dispersion de l'eau, ladite buse étant en général portée par un porte buse, éventuellement solidaire du piston creux.The number of components to be lifted by the piston is much more limited in this design than when the driving part is integrated in the piston or located above the piston so the weight to lift is less. As a result, the piston responds to a lower water pressure which is an advantage; vertically moving parts are subject to frequent wear and tear. Thanks to the design according to the invention, these parts are immediately accessible which greatly facilitates maintenance unlike a sprinkler of conventional design. The watering devices described above comprise in general and without limitation, a piston chamber resting on a bottom and comprising a hollow piston, movable in the inner part of the piston chamber, said piston passing through the upper part of said piston chamber is coming to the right of an orifice in the bottom through which the water flows, the sealing of the assembly being ensured by adequate means. The mobile piston comprises at its upper part a watering head, possibly integral with said piston, at least in its continuity, and comprising at least one nozzle ensuring the dispersion of the water, said nozzle being generally carried by a door nozzle, optionally integral with the hollow piston.
En outre, ces dispositifs comportent un moyen de rappel du piston vers le bas, pouvant être constitué par exemple d'un ressort hélicoïdal de rappel disposé à l'intérieur de la chambre piston et pouvant prendre appui d'une part sur la face interne de la partie supérieure de ladite chambre piston et d'autre part sur la face externe de la partie basse du piston.In addition, these devices comprise a return means of the piston downwards, which may be constituted for example by a helical return spring disposed inside the piston chamber and which can bear on the one hand on the inner face of the piston. the upper part of said piston chamber and secondly on the outer face of the lower part of the piston.
Enfin ces dispositifs comporte en général un moyen mécanique placé dans le passage de l'eau, soit à l'intérieur de l'ensemble porte buse / piston, soit à l'extérieur de la buse, ledit moyen mécanique étant élaboré pour sous l'effet de la pression de l'eau entraîner en rotation dans un plan horizontal à tout le moins le porte buse, au mieux l'ensemble porte buse / piston.Finally, these devices generally comprise a mechanical means placed in the passage of the water, either inside the nozzle / piston holder assembly, or outside the nozzle, said mechanical means being developed for under the effect of the pressure of the water rotate in a horizontal plane at least the nozzle holder, at best the nozzle / piston holder assembly.
Le dispositif d'arrosage selon l'invention ainsi d'ailleurs que l'arroseur de jardin selon l'invention, reprend l'essentiel du mécanisme des dispositifs d'arrosage et/ou des arroseurs précédemment décrits en substituant dans ceux-ci le moyen mécanique d'entraînement en rotation de la buse d'arrosage par un dispositif électrique.The watering device according to the invention as well as the garden sprinkler according to the invention, takes up the essence of the mechanism of the watering devices and / or sprinklers described above substituting in them the means mechanical drive in rotation of the watering nozzle by an electric device.
Selon l'invention ledit dispositif d'entraînement en rotation de la buse (par après dans le texte "l'entraînement") est constitué d'un moteur électrique et d'une transmission sous la forme d'un réducteur comprenant au moins un engrenage. Ainsi l'invention concerne donc un dispositif d'entraînement électrique à alimentation externe pour arroseur comprenant au moins a. un moteur électrique, b. une transmission sous la forme d'un réducteur comprenant au moins un engrenage, c. un boîtier (boîtier d'entraînement) dans lequel sont positionnés le moteur électrique et la transmission, présentant en son centre un orifice, caractérisé en ce qu'il comprend un arbre de sortie creux en son centre, qui est un engrenage destiné à reprendre le mouvement de rotation du réducteur et à Ie transmettre au piston qui assure le mouvement d'élévation de l'arroseur et en ce qu'il comprend un plateau comportant un orifice en son centre, ledit plateau étant solidaire d'une part dudit arbre de sortie creux, et d'autre part, solidaire de la chambre piston de l'arroseur afin d'en assurer outre la rotation, l'étanchéité ainsi qu'une séparation distinctes des deux fonctions principales que sont la rotation et l'élévation.According to the invention, said device for rotating the nozzle (hereinafter in the text "the drive") consists of an electric motor and a transmission in the form of a gearbox comprising at least one gear . Thus, the invention relates to an external power drive device for sprinkler comprising at least a. an electric motor, b. a transmission in the form of a gearbox comprising at least one gear, c. a housing (drive box) in which are positioned the electric motor and the transmission, having in its center an orifice, characterized in that it comprises a hollow output shaft at its center, which is a gear intended to take over the rotational movement of the reducer and to transmit it to the piston which ensures the elevation movement of the sprinkler and in that it comprises a plate having an orifice at its center, said plate being integral on the one hand with said output shaft hollow, and secondly, secured to the piston chamber of the sprinkler to ensure in addition to rotation, sealing and separate separation of the two main functions of rotation and elevation.
Selon l'invention, le moteur électrique peut être tout moteur électrique que l'Homme du Métier n'aura aucun mal à choisir parmi ceux disponibles dans l'art antérieur en fonction de la taille de l'arroseur à motoriser, de la puissance désirée et/ou de tout autre paramètre liés à l'emploi particulier de celui-ci parfaitement connu de l'Homme duAccording to the invention, the electric motor can be any electric motor that the skilled person will have no trouble choosing from those available in the prior art depending on the size of the sprinkler motorize, the desired power and / or any other parameter related to the particular use of this one perfectly known to the Man of the

Selon l'invention, le réducteur peut comprendre au moins un engrenage que l'on peut imaginer n'être qu'une simple petite roue crantée positionnée en sortie de l'axe du moteur et transmettant directement le mouvement de rotation dudit axe du moteur à l'élément devant être entraîné.According to the invention, the gearbox may comprise at least one gear that can be imagined to be a simple small toothed wheel positioned at the output of the motor shaft and directly transmitting the rotational movement of said motor shaft to the element to be trained.
Préférentiellement, indépendamment de la simple petite roue crantée positionnée en sortie de l'axe du moteur, le réducteur peut comprendre en outre au moins un autre engrenage, ledit engrenage étant préférentiellement constitué d'une roue crantée dont le diamètre sera adapté sans difficulté par l'Homme du Métier en fonction de la taille de l'élément à mettre en mouvement, par exemple un arroseur, de la puissance du moteur utilisé et/ou de tout autre paramètre liés à l'emploi particulier de celui-ci parfaitement connu de l'Homme du Métier.Preferably, independently of the simple small toothed wheel positioned at the output of the axis of the motor, the gearbox may further comprise at least one other gear, said gear preferably being constituted by a toothed wheel whose diameter will be adapted without difficulty by the Skilled in the art depending on the size of the element to be set in motion, for example a sprinkler, the power of the engine used and / or any other parameter related to the particular use of it perfectly known to the 'Man of the Occupation.
L'Homme du Métier sait en outre adapter le nombre d'engrenages nécessaire à la réalisation du réducteur en fonction de la réduction désirée.The skilled person also knows how to adapt the number of gears necessary for the realization of the reducer according to the desired reduction.
