Description

Dispositif solaire photovoltaïque autonome portable Stand-alone solar photovoltaic device
Domaine techniqueTechnical area
[0001] La présente invention concerne un dispositif photovoltaïque autonome portable, en particulier mais pas exclusivement un système d'éclairage alimenté par un capteur photovoltaïque.The present invention relates to a portable autonomous photovoltaic device, particularly but not exclusively a lighting system powered by a photovoltaic sensor.
Etat de la techniqueState of the art
[0002] On connaît dans l'art antérieur des lampes d'extérieur associées à un capteur photovoltaïque et à une batterie. La batterie est rechargée durant la journée afin d'alimenter la lampe durant la nuit. Ces dispositifs sont souvent relativement compacts et comportent une seule lampe ou un seul réflecteur. Plusieurs lampes de ce type sont nécessaires afin d'éclairer une surface importante, ce qui multiplie le nombre de batteries et de régulateurs nécessaires, et donc le coût de l'ensemble du système.[0002] In the prior art, outdoor lamps associated with a photovoltaic sensor and a battery are known. The battery is recharged during the day to power the lamp during the night. These devices are often relatively compact and have a single lamp or a single reflector. Several lamps of this type are needed to illuminate a large area, which multiplies the number of batteries and regulators needed, and therefore the cost of the entire system.
[0003] On connaît aussi des installations d'éclairage plus importantes comportant des capteurs photovoltaïques, une batterie de type automobile, un régulateur et une lampe de plus grande puissance. Ces installations sont souvent fixes. Le poids de la batterie et le grand nombre de composants séparés rendent en tous les cas ces installations difficiles à transporter.[0003] There are also known larger lighting installations comprising photovoltaic sensors, a battery of automobile type, a regulator and a lamp of greater power. These facilities are often fixed. The weight of the battery and the large number of separate components in any case make these facilities difficult to transport.
Bref résumé de l'inventionBrief summary of the invention
[0004] Un but de la présente invention est de proposer un nouveau dispositif photovoltaïque transportable mais néanmoins adapté à l'éclairage d'une surface importante. [0005] Selon l'invention, ces buts sont atteints notamment au moyen d'un dispositif photovoltaïque autonome portable comprenant :An object of the present invention is to provide a new transportable photovoltaic device but nevertheless suitable for lighting a large area. According to the invention, these objects are achieved in particular by means of a portable autonomous photovoltaic device comprising:
Un support creux en deux parties sensiblement coaxiales assemblées l'une à l'autre ;A hollow support in two substantially coaxial parts assembled to each other;
Un capteur photovoltaïque souple enroulé ;A flexible photovoltaic sensor wound;
Une batterie montée dans la première desdites parties et destinée à stocker l'énergie électrique produite par ledit capteur photovoltaïque ;A battery mounted in the first of said portions and for storing electrical energy produced by said photovoltaic sensor;
Un circuit électronique de contrôle pour la gestion de la charge de la batterie, monté dans ladite première partie ;An electronic control circuit for managing the charge of the battery, mounted in said first part;
Un système d'éclairage comportant plusieurs lampes à leds rangées à l'intérieur dudit capteur photovoltaïque enroulé et à l'intérieur de la deuxième desdites parties.A lighting system comprising a plurality of LED lamps stored inside said coiled photovoltaic sensor and inside the second of said parts.
[0006] Ce dispositif présente notamment l'avantage de réunir dans un seul support tous les composants nécessaires à la production et au stockage d'électricité et à l'utilisation de cette électricité pour alimenter plusieurs lampes. Le dispositif est avantageusement autonome et transportable par une personne seule de taille adulte. Le dispositif solaire photovoltaïque constitue donc un ensemble de pièces assemblées entre elles, adaptées les unes aux autres, et permettant un rangement optimal.This device has the advantage of bringing together in a single support all the components necessary for the production and storage of electricity and the use of this electricity to power several lamps. The device is advantageously autonomous and transportable by a single person of adult size. The solar photovoltaic device is therefore a set of parts assembled together, adapted to each other, and for optimal storage.
[0007] L'utilisation d'un support de préférence cylindrique ou éventuellement parallélipipédique permet d'optimiser le rangement du panneau solaire flexible qui peut simplement être enroulé. Les autres composants du dispositif, notamment les lampes et la pompe optionnelle, sont rangées à l'intérieur du panneau roulé, ou en bout de panneau à l'instar des batteries et de l'électronique.The use of a support preferably cylindrical or possibly parallelepiped optimizes the storage of the flexible solar panel that can simply be rolled up. The other components of the device, including lamps and the optional pump, are stored inside the rolled panel, or at the end of the panel like batteries and electronics.
[0008] II est ainsi possible de disposer dans un seul dispositif compact, cylindrique et donc facile à transporter sur l'épaule, un panneau solaire de grande dimension avec tous les composants nécessaires à l'assemblage d'un système photovoltaïque complet avec plusieurs lampes. Brève description des figuresIt is thus possible to have in a single compact device, cylindrical and therefore easy to carry on the shoulder, a large solar panel with all the components necessary for the assembly of a complete photovoltaic system with several lamps .

Exemple(s) de mode de réalisation de l'inventionExample (s) of embodiment of the invention
[0016] La figure 1 illustre de manière schématique un dispositif selon une première variante de l'invention. Le dispositif comporte un support cylindrique en deux parties 1 et 2. Le support est de préférence cylindrique ou parallélépipédique et les deux parties 1, 2 sont emboîtées ou vissées coaxialement l'une à l'autre. Le support peut être fabriqué en matière plastique moulée ou injectée, en métal ou dans un autre matériau souple, résistant aux chocs, aux déformations et à la chaleur, et insensible aux huiles et aux solvants.Figure 1 schematically illustrates a device according to a first variant of the invention. The device comprises a cylindrical support in two parts 1 and 2. The support is preferably cylindrical or parallelepipedic and the two parts 1, 2 are nested or screwed coaxially to each other. The support may be made of molded or injected plastic, metal or other flexible material, resistant to shocks, deformations and heat, and insensitive to oils and solvents.
[0017] Ce support constitue un espace de rangement étanche pour différents éléments du dispositif, notamment une batterie 4, un circuit électronique 3 de contrôle de charge de la batterie et un dispositif d'éclairage comportant plusieurs lampes 8, de préférence des lampes d'éclairage à led. Le support peut être fermé par un couvercle amovible 20 étanche à l'une ou à chaque extrémité. Des câbles permettant de connecter électriquement ces composants peuvent être rangés dans le support.This support is a sealed storage space for various elements of the device, including a battery 4, an electronic circuit 3 battery charge control and a lighting device comprising a plurality of lamps 8, preferably lamps. led lighting. The support can be closed by a removable cover 20 sealed at one or each end. Cables for electrically connecting these components can be stored in the holder.
[0018] La batterie 4 est constituée par un ensemble d'accumulateurs électriques reliés entre eux de façon à créer un générateur de courant continu délivrant la tension et le courant désirés. Il est aussi possible d'utiliser une amorce, c'est-à-dire un système de stockage d'énergie de grande puissance capable de fournir la puissance énergétique nécessaire au démarrage de machines telles que pompes hydrauliques. Une amorce permet de restituer l'énergie électrique plus rapidement qu'une batterie classique. Si le dispositif est utilisé pour faire fonctionner une pompe hydraulique, il est par exemple possible de démarrer la pompe avec l'énergie fournie par l'amorce ; une fois le démarrage terminé, l'électronique de contrôle commute automatique la batterie qui prend le relais après l'amorce, afin d'assurer l'alimentation de la pompe lors du fonctionnement normal.The battery 4 is constituted by a set of electrical accumulators connected together so as to create a direct current generator delivering the desired voltage and current. It is also possible to use a primer, that is to say a high-power energy storage system capable of providing the power required to start machines such as hydraulic pumps. A primer can restore the electrical energy faster than a conventional battery. If the device is used to operate a hydraulic pump, it is for example possible to start the pump with the energy provided by the primer; once the start is complete, the control electronics automatically switches the battery that takes over after the priming, in order to supply power to the pump during normal operation.
[0019] Le circuit électronique 3 assure la gestion de la charge et de la décharge de la batterie, et permet d'éviter un vieillissement prématuré de la batterie. En cas de dysfonctionnement du système, l'électronique de contrôle 3 empêche notamment la décharge complète de la batterie ce qui la rendrait inutilisable. L'électronique peut également gérer le système d'éclairage ou le système de charge d'appareils électriques ou électroniques, ainsi qu'une éventuelle amorce. [0020] L'éclairage 8 est basé sur des leds (diodes électroluminescentes) avec une puissance de 1 Watt ou de quelque Watts. Chaque led est avantageusement munie d'une lentille pour faire converger ou diverger les rayons lumineux. Plusieurs leds sont avantageusement connectées l'une à l'autre afin de produire la lumière nécessaire L'ensemble est placé dans un boitier qui peut être utilisé comme spot ou comme une lampe classique.The electronic circuit 3 provides the management of the charge and the discharge of the battery, and avoids premature aging of the battery. In the event of a malfunction of the system, the control electronics 3 prevents in particular the complete discharge of the battery which would render it unusable. The electronics can also manage the lighting system or charging system of electrical or electronic devices, as well as a possible primer. Lighting 8 is based on LEDs (light emitting diodes) with a power of 1 Watt or some Watts. Each LED is advantageously provided with a lens to converge or diverge the light rays. Several LEDs are advantageously connected to each other in order to produce the necessary light. The set is placed in a case that can be used as a spotlight or as a conventional lamp.
[0021] Le dispositif de la figure 1 comporte en outre un capteur photovoltaïque souple et flexible, enroulé dans cet exemple autour du support 1,2. Le capteur est de préférence produit à partir d'un rouleau à partir d'un support plastique souple et découpé à la longueur désirée. Une sangle ou un velcro non représenté permet de maintenir le capteur enroulé lors du transport. Les cellules photovoltaïques sont de préférence disposées sur la face interne du capteur enroulé. L'extrémité interne du capteur peut être liée de façon permanente au support 1,2, ou à l'une des parties du support, qui sert ainsi de base lors du montage du capteur déployé. Afin de rendre le capteur photovoltaïque autoportant lorsqu'il est déployé, le dispositif peut comporter une structure qui l'encadre et le rend rigide après le montageThe device of Figure 1 further comprises a flexible and flexible photovoltaic sensor, wound in this example around the support 1.2. The sensor is preferably produced from a roll from a flexible plastic support and cut to the desired length. A strap or velcro not shown keeps the sensor wound during transport. The photovoltaic cells are preferably arranged on the inner face of the wound sensor. The inner end of the sensor can be permanently connected to the support 1, 2, or to one of the parts of the support, which thus serves as a basis for mounting the deployed sensor. In order to make the photovoltaic sensor self-supporting when it is deployed, the device may comprise a structure that frames it and makes it rigid after assembly.
[0022] Le dispositif peut en outre comporter des prises ou des fiches permettant le chargement d'appareils électriques ou électroniques connectés. Il est possible de prévoir des prises dédiées à un ou plusieurs fabricants, et/ou des prises universelles sur lesquelles peuvent se brancher les prises dédiées des fabricants.The device may further comprise sockets or plugs for charging connected electrical or electronic devices. It is possible to provide dedicated outlets for one or more manufacturers, and / or universal outlets on which can connect the dedicated outlets manufacturers.
[0023] Les figures 2 à 6 illustrent une deuxième variante de dispositif photovoltaïque selon l'invention, dans laquelle le panneau photovoltaïque flexible est enroulé à l'intérieur du support 1, 2. La figure 2 illustre une vue en perspective du support en deux parties 1, 2 fermé pour le transport. La longueur typique du support 1, 2 est de l'ordre de 100 à 120 centimètres et son diamètre d'environ 15 à 20 centimètres, suffisant pour stocker un capteur solaire d'environ 0.8 à 1.2 mètres carrés ainsi que les autres éléments du dispositif. Le support peut de préférence tenir debout seul, ou être couché ; des pieds ou un replat non représentés peuvent être prévus pour tenir le cylindre couché et l'empêcher de rouler.Figures 2 to 6 illustrate a second variant of photovoltaic device according to the invention, wherein the flexible photovoltaic panel is wound inside the support 1, 2. Figure 2 illustrates a perspective view of the support in two parts 1, 2 closed for transport. The typical length of the support 1, 2 is of the order of 100 to 120 centimeters and its diameter of about 15 to 20 centimeters, sufficient to store a solar collector of about 0.8 to 1.2 square meters and the other elements of the device . The support can preferably stand alone, or laid ; unrepresented feet or flats may be provided to hold the cylinder recumbent and prevent it from rolling.

L'électronique 3 comporte en outre des transformateurs ou convertisseurs de tension pour fournir les niveaux de tension adaptés aux différents connecteurs.FIG. 3 illustrates a perspective view of the first part of the support 1, shown in transparency in order to show the battery 4, the electronic control circuit 3 for the management of the charge of the battery, the connectors 30 for the 9 connection cables to the panel and the lamps, and the connectors 31 or plugs for recharging electrical or electronic devices. The batteries 4 are preferably mounted at the bottom of the part 1 and closed by a removable plate carrying the connectors 30, 31 and the electronics 3. The electronics 3 further comprises transformers or voltage converters to provide the voltage levels adapted to different connectors.
[0025] La plaque amovible 33 est de préférence montée en retrait dans la partie 1, laissant un espace cylindrique pour ranger l'extrémité du capteur et du boîtier de rangement décrits plus loin. Elle peut être démontée, par exemple à l'aide de vis, afin de remplacer la batterie. L'électronique 3 est de préférence montée sur la face inférieure de la plaque amovible 33, tandis que la face supérieure comporte plusieurs connecteurs 31 pour y connecter les câbles amovibles 9 permettant de lier le circuit électronique 3 au panneau solaire 5 d'une part et aux lampes 8 d'autre part. D'autres connecteurs ou fiches 32 peuvent encore être prévus sur la face supérieure de la plaque 33, par exemple des connecteurs de type allume-cigare, USB, etc. D'autres organes de commande, par exemple des interrupteurs, des fusibles d'entrée et de sortie, des lampes ou affichages de contrôle ou pour afficher l'état de charge de la batterie, etc peuvent encore être montés sur la face supérieure externe de la plaque 33.The removable plate 33 is preferably recessed in part 1, leaving a cylindrical space to store the end of the sensor and the storage housing described below. It can be disassembled, for example using screws, to replace the battery. The electronics 3 is preferably mounted on the underside of the removable plate 33, while the upper face has several connectors 31 for connecting the removable cables 9 for connecting the electronic circuit 3 to the solar panel 5 on the one hand and to the lamps 8 on the other hand. Other connectors or plugs 32 may also be provided on the upper face of the plate 33, for example connectors of cigarette lighter type, USB, etc.. Other control devices, for example switches, input and output fuses, lamps or control displays or to display the state of charge of the battery, etc. can still be mounted on the outer upper face of the plate 33.
[0026] Dans une variante non illustrée, deux plaques distinctes sont prévues au-dessus des batteries 4 : une première plaque de circuit imprimé 33 portant l'électronique, et une plaque additionnelle superposée pardessus ce circuit imprimé et portant les connecteurs. La plaque supérieure peut être une simple plaque de plastique ou d'aluminium et n'a pas besoin de pistes imprimées ; les connecteurs sont reliés à la plaque inférieure par des câbles ou des fils discrets. Les plaques peuvent être chassées à l'intérieur du cylindre, et maintenues par leur périphérie et en appui contre une portée non représentée à l'intérieur du cylindre ; un joint permet éventuellement de les sceller. Il est aussi possible de prévoir une bague annulaire vissée à l'intérieur du cylindre pour maintenir la ou les plaques 33 en appui contre cette portée.In a variant not shown, two separate plates are provided above the batteries 4: a first printed circuit board 33 carrying the electronics, and an additional plate superimposed over this printed circuit and carrying the connectors. The top plate can be a simple plastic or aluminum plate and does not need printed tracks; the connectors are connected to the bottom plate by cables or discrete wires. The plates can be driven inside the cylinder, and held by their periphery and supported against a range not shown inside the cylinder; a seal can be used to seal them. It is also possible to provide an annular ring screwed inside the cylinder to keep the plate or plates 33 against this bearing.
[0027] La seconde partie 2 du support 1, 2 est illustrée sur la figure 4. Les deux parties 1, 2 sont destinées à être assemblées coaxialement l'une à l'autre, par exemple en les vissant, en les clipsant, avec un assemblage à baillonnette, ou simplement en insérant une partie dans l'autre. La liaison entre les deux parties est de préférence étanche ou au moins protégée contre les projections de liquide.The second part 2 of the support 1, 2 is illustrated in Figure 4. The two parts 1, 2 are intended to be assembled coaxially to one another, for example by screwing them, by clipping, with a bayonet assembly, or simply by inserting one part into the other. The connection between the two parts is preferably sealed or at least protected against splashing liquid.
[0028] La deuxième partie de support 2 est destinée à ranger le panneau solaire 5 flexible enroulé à l'intérieur du support. Une portion de ce panneau dépasse hors du tube et est destinée à être logée dans l'espace cylindrique libre dans la première partie du support 1. Cette partie peut être femrée d'un côté par un couvercle vissé ou collé.The second support portion 2 is intended to store the flexible solar panel 5 wound inside the support. A portion of this panel protrudes out of the tube and is intended to be housed in the free cylindrical space in the first part of the support 1. This part may be closed on one side by a screwed or glued lid.
[0029] Des tiges de montage 7 sont rangées dans une poche 20 à l'extérieur du support, par exemple une poche dans le même matériau que le support et collée contre la face externe du support après l'injection de ce dernier. Dans une autre variante, le tube est fabriqué par extrusion d'un matériau céramique ou aluminium ; dans ce cas, la poche 20 est avantageusement extrudée au cours de la même opération. Un gainage synthétique peut être prévu autour du tube en aluminium extrudé.Mounting rods 7 are stored in a pocket 20 outside the support, for example a pocket in the same material as the support and glued against the outer face of the support after the injection of the latter. In another variant, the tube is manufactured by extrusion of a ceramic or aluminum material; in this case, the pocket 20 is advantageously extruded during the same operation. A synthetic sheath can be provided around the extruded aluminum tube.
[0030] Ces tiges flexibles, par exemple en fibre de verre, sont destinées à être assemblées afin de monter et de rigidifier le panneau solaire, comme illustré sur la figure 6. La deuxième partie comporte en outre une poignée ou, comme dans l'exemple illustré, une sangle 10 pour le transport du dispositif plié. [0031] La deuxième partie du support 2 comporte en outre un boîtier de rangement 6 pour le rangement des lampes 8 et des câbles 9. Un exemple de boîtier est illustré sur la figure 5, fermé puis ouvert. Dans ce mode de réalisation, le boitier est formé de deux parties semi-cylindriques assembles de manière à constituer un cylindre qui peut être rangé à l'intérieur du panneau 5 enroulé. Différentes lampes 8 (huit lampes dans cet exemple) sont rangées coaxialement dans des espaces de rangement appropriés dans la base du boîtier. D'autres espaces de rangement sont aussi prévus pour les câbles de connexion 9. La base hémicylindrique vient se refermer au-dessus du couvercle. Le boîtier est destiné à être rangé dans le support 1,2 étanche et n'a donc pas besoin d'être étanche lui-même.These flexible rods, for example fiberglass, are intended to be assembled to mount and stiffen the solar panel, as shown in Figure 6. The second part further comprises a handle or, as in the illustrated example, a strap 10 for transporting the folded device. The second part of the support 2 further comprises a storage box 6 for storing the lamps 8 and cables 9. An example of a housing is shown in Figure 5, closed and open. In this embodiment, the case is formed of two semi-cylindrical parts assembled so as to form a cylinder which can be stored inside the wound panel. Different lamps 8 (eight lamps in this example) are arranged coaxially in appropriate storage spaces in the base of the housing. Other storage spaces are also provided for the connection cables 9. The semicylindrical base is closed above the lid. The housing is intended to be stored in the waterproof support 1.2 and therefore does not need to be waterproof itself.
[0032] D'autres dispositifs peuvent être rangés dans le boîtier 6, par exemple une amorce, une pompe hydraulique etc.Other devices can be stored in the housing 6, for example a primer, a hydraulic pump, etc.
[0033] Les dimensions des différents éléments sont soigneusement sélectionnées de façon à être adaptées les unes aux autres. Par exemple, le diamètre externe des lampes permet de les ranger dans le boîtier 6 qui peut juste être logé à l'intérieur du panneau roulé dans le support 1, 2. De la même façon, les caractéristiques électriques du panneau solaire, de l'électronique, de la batterie et des lampes sont parfaitement adaptées entre elles. Le dispositif, bien que constitué de différentes pièces, constitue donc un ensemble homogène.The dimensions of the various elements are carefully selected to be adapted to each other. For example, the outer diameter of the lamps can be stored in the housing 6 which can just be housed inside the panel rolled in the support 1, 2. In the same way, the electrical characteristics of the solar panel, the electronic, battery and lamps are perfectly adapted to each other. The device, although composed of different parts, therefore constitutes a homogeneous whole.
[0034] La figure 6 illustre schématiquement le dispositif monté avec le capteur solaire 5 assemblé et rigidifié grâce aux tiges 7, et relié grâce aux câbles 9 au circuit électronique 3 dans la première partie du support 1. Les tiges permettent de préférence d'autres formes de montage, y compris un montage en appui contre une surface verticale, etc. Des poches ou des œillets permettent de lier les tiges au capteur solaire monté dans l'exemple illustré sur un support rectangulaire textile ou plastique avec une oreillette à chaque coin ; un support rectangulaire est aussi possible. Numéros de référence employés sur les figuresFigure 6 schematically illustrates the device mounted with the solar collector 5 assembled and stiffened thanks to the rods 7, and connected through the cables 9 to the electronic circuit 3 in the first part of the support 1. The rods preferably allow other mounting forms, including mounting against a vertical surface, etc. Pockets or eyelets connect the rods to the solar collector mounted in the illustrated example on a rectangular textile or plastic support with an atrium at each corner; a rectangular support is also possible.
