Description

DISPOSITIF SUPPORT DE PANNEAU PHOTOVOLTAIQUE PHOTOVOLTAIC PANEL SUPPORT DEVICE
La présente invention concerne un dispositif support de panneau photovoltaïque plus particulièrement applicable dans les zones cycloniques . The present invention relates to a photovoltaic panel support device more particularly applicable in cyclonic zones.
La présente invention entre dans le domaine d' installation de panneaux photovoltaïques au sol ou en terrasse, et plus précisément, mais non exclusivement, sur des sols accidentés et non terrassés, et susceptibles d'être soumises à de forts vents .  The present invention is in the field of installation of photovoltaic panels on the ground or terrace, and more specifically, but not exclusively, on uneven and uneven ground, and likely to be subject to strong winds.
De manière usuelle, les installations photovoltaïques, comportent un ou plusieurs panneaux photovoltaïques reposant sur un support composé d' une infrastructure reposant sur le sol et d' une superstructure soutenant lesdits panneaux photovoltaïques, ladite superstructure étant reliée par des moyens de liaison à l'infrastructure. Dans la majorité des cas la superstructure présentera une inclinaison destinée à améliorer la production des panneaux photovoltaïques .  Usually, the photovoltaic installations comprise one or more photovoltaic panels resting on a support composed of an infrastructure resting on the ground and of a superstructure supporting said photovoltaic panels, said superstructure being connected by means of connection to the infrastructure . In most cases, the superstructure will have an inclination to improve the production of photovoltaic panels.
D'ordre général, ladite superstructure se compose d'une armature qui peut être en bois, en métal ou autres matériaux, formant un cadre sur lequel vient reposer le ou les panneaux photovoltaïques . Ledit cadre peut être lui-même constitué de plusieurs cadres assemblés ou non afin d' apporter bonne une résistance mécanique à la superstructure.  Of a general nature, said superstructure consists of an armature that can be made of wood, metal or other materials, forming a frame on which comes to rest the photovoltaic panel (s). Said frame may itself consist of several frames assembled or not to provide good mechanical strength to the superstructure.
Plus particulièrement, un problème se pose lorsque ces installations de supports sont placées dans des zones géographiques soumises à un climat rigoureux, notamment du fait de fortes chutes de neige ou de forte rafales de vent, les supports des panneaux photovoltaïques étant dimensionnés en fonctions des efforts qu'ils subissent de ces conditions météorologiques pouvant être extrêmes. Plus précisément, il est nécessaire de connaître ces efforts pour adapter la taille de l'infrastructure et de la superstructure recevant les panneaux photovoltaïques .  More particularly, a problem arises when these media installations are placed in geographical areas subject to a harsh climate, in particular because of heavy snowfall or strong gusts of wind, the supports of the photovoltaic panels being dimensioned in function of the forces they suffer from these extreme weather conditions. More precisely, it is necessary to know these efforts to adapt the size of the infrastructure and the superstructure receiving the photovoltaic panels.
En effet, dans ces zones météorologiques l'on peut calculer les efforts que subit une installation de support pour panneaux photovoltaïques disposés sur terrain plat tel une plaine soumise à un fort vent parallèle au sol . Bien évidemment ces efforts sont dépendants du sens d'attaque de l'installation par le vent entraînant divers effets du fait de l'inclinaison de la superstructure. Indeed, in these meteorological zones it is possible to calculate the efforts that a support installation for photovoltaic panels arranged on flat ground like a plain subjected to a strong wind parallel to the ground. Obviously these efforts are dependent on the direction of attack of the installation by the wind causing various effects due to the inclination of the superstructure.
Selon un premier sens du vent, l'infrastructure et la superstructure subiraient de violents efforts au soulèvement et au basculement pouvant entraîner une détérioration de 1' installation .  In a first wind direction, the infrastructure and the superstructure would be subjected to violent lifting and tilting forces which could lead to deterioration of the installation.
Si le vent vient en sens contraire, l'installation est soumise à un effort d'écrasement et au basculement, entraînant, là encore, un déplacement du centre de poussée sur la longueur de la superstructure.  If the wind comes in the opposite direction, the installation is subjected to a crushing effort and tilting, causing, again, a displacement of the center of thrust over the length of the superstructure.
Si le vent est composé plusieurs composantes de directions, l'installation est alors soumise à une combinaison de ces efforts.  If the wind is composed of several components of directions, the installation is then subjected to a combination of these efforts.
Afin de contrer les effets de soulèvement et de basculement, l'infrastructure est classiquement réalisée par la pose de longrines, de pieux battus ou de micropieux sur le site d' installation des panneaux photovoltaïques . En fonction du site, il est encore utilisé le coulage d'un massif de béton qui va servir d'infrastructure. De plus, le choix de la constitution de l'infrastructure peut être soumis à une étude géotechnique du site d'installation.  In order to counter the lifting and tilting effects, the infrastructure is conventionally carried out by the installation of longrins, piles or micropiles at the installation site of the photovoltaic panels. Depending on the site, it is still used pouring a concrete block that will serve as an infrastructure. In addition, the choice of the constitution of the infrastructure may be subject to a geotechnical study of the installation site.
Ces solutions classiques présentent l'inconvénient principal lors de la mise en place des supports de panneaux photovoltaïques de nécessiter la mobilisation d' engins spéciaux pour leur mise en œuvre .  These conventional solutions have the main disadvantage when setting up the photovoltaic panel supports to require the mobilization of special machines for their implementation.
D'ailleurs, il est à noter que beaucoup de sites d' installation nécessitent eux-mêmes un aménagement adapté pour permettre l'accès de ces engins spéciaux au lieu d' installation .  Moreover, it should be noted that many installation sites themselves require an adapted layout to allow access of these special machines to the installation site.
Il en va de même une fois la période d' exploitation terminée. En effet, ces solutions durables rendent long et difficile le démantèlement complet des installations de support . Afin de faciliter l'installation mais aussi le démantèlement de tels support à l'issue de la période d'exploitation, il est décrit dans le document WO 2004/048862 l'utilisation de support comportant une superstructure simplement déposée sur le sol, conçue apte à être lestée par des cailloux ou encore plusieurs poids adaptés. The same is true once the operating period is over. Indeed, these durable solutions make long and difficult the complete dismantling of support facilities. In order to facilitate the installation but also the dismantling of such supports at the end of the exploitation period, it is described in document WO 2004/048862 the use of a support comprising a superstructure simply deposited on the ground, designed suitable to be ballasted by pebbles or several adapted weights.
Cette solution simple n'est pas exempte de défaut, tout particulièrement, il n'y a aucun moyen de maîtriser précisément la charge de leste nécessaire et encore moins le centrage de cette dernière. En effet, le centrage du lest est très important car il est le garant de la prévention d'un basculement lié au vent .  This simple solution is not free of defects, in particular, there is no way to precisely control the weight load necessary, let alone the centering of the latter. Indeed, the centering of the ballast is very important because it is the guarantor of the prevention of a tilting related to the wind.
De plus, une telle solution introduit des inconnues quant à sa fiabilité qui ne peut garantir une intégrité suffisante de l'installation sur la durée de l'exploitation qui est d'ordre général fixée à vingt ans. En somme, un lest réalisé par des cailloux ou des poids peut être dans le temps déplacé par les vibrations liées aux rafales de vent entraînant une érosion et à terme la ruine de l'installation.  In addition, such a solution introduces unknowns as to its reliability which can not guarantee a sufficient integrity of the installation over the period of operation which is of a general nature set at twenty years. In short, a ballast made by pebbles or weights can be displaced in time by vibrations related to gusts of wind causing erosion and eventually the ruin of the installation.
L'invention a pour but de pallier les inconvénients de l'état de la technique en proposant un dispositif support de panneaux photovoltaïques résistant au effort induit par les aléas du climat et proposant une installation et un démantèlement aisé .  The invention aims to overcome the disadvantages of the state of the art by proposing a support device for photovoltaic panels resistant to stress induced by climate hazards and proposing easy installation and dismantling.
Ainsi, l'invention concerne un dispositif support de panneau photovoltaïque caractérisé par le fait qu'il est autostable au basculement, il comporte à cet effet une embase reposant sur trois pieds, une superstructure plane destinée à recevoir le ou les panneaux photovoltaïques, ladite superstructure étant reliée à l'embase au travers de moyens de liaison maintenant ladite superstructure plane selon une inclinaison particulière, ladite embase faisant lest et déterminant le centre de gravité dudit dispositif support, tandis que ladite inclinaison est choisie en sorte que le centre de poussée soit disposé en arrière du centre de gravité par rapport au bord horizontal le plus haut de ladite superstructure . Thus, the invention relates to a photovoltaic panel support device characterized in that it is autostable tilt, it comprises for this purpose a base resting on three feet, a flat superstructure for receiving the photovoltaic panel or panels, said superstructure being connected to the base through connection means holding said plane superstructure in a particular inclination, said base forming weight and determining the center of gravity of said support device, while said inclination is chosen so that the center of thrust is disposed behind the center of gravity relative to the highest horizontal edge of said superstructure.
Selon une autre caractéristique de l'invention, ladite embase est réalisée en béton armé préfabriqué .  According to another characteristic of the invention, said base is made of prefabricated reinforced concrete.
Selon encore une autre caractéristique de l'invention, lesdits moyens de liaison sont constitués par des montants reliant l'embase à la superstructure conformés sous la forme d'un treillis de poutre augmentant la résistance de l'ensemble et équilibrant les charges entre les différentes fixations .  According to yet another characteristic of the invention, said connecting means are constituted by uprights connecting the base to the superstructure shaped in the form of a beam trellis increasing the strength of the assembly and balancing the loads between the different fixations.
Selon encore une autre caractéristique de l'invention, lesdits montants viennent se fixer sur les flancs de ladite embase et/ou de ladite superstructure.  According to yet another characteristic of the invention, said amounts are fixed on the sides of said base and / or said superstructure.
D'autres caractéristiques et avantages de l'invention ressortiront de la description détaillée qui va suivre des modes de réalisation non limitatifs de l'invention, en référence aux figures annexées dans lesquelles :  Other characteristics and advantages of the invention will emerge from the following detailed description of non-limiting embodiments of the invention, with reference to the appended figures in which:
- la figure 1 représente de profil et de manière schématisée un dispositif support de panneaux photovoltaïques selon l'invention; et  - Figure 1 is a profile and schematically a support device for photovoltaic panels according to the invention; and
- la figure 2 représente en perspective et façon schématisée un de dessous support de panneaux photovoltaïques selon 1 ' invention .  - Figure 2 shows in perspective and schematically one of the support of photovoltaic panels according to the invention.
La présente invention entre dans le domaine des dispositifs supports de panneaux photovoltaïques destinés en particulier à être installé dans des zones cycloniques, sur des sols accidentés non terrassés ou en terrasse.  The present invention is in the field of support devices for photovoltaic panels intended in particular to be installed in cyclonic zones, on uneven ground not terraced or terrace.
Tel que visible sur la figure 1, un tel dispositif de support 1 de panneaux photovoltaïques 2 est autostable au basculement et comporte une embase 3 conçu apte à servir de lest, une superstructure 4 plane prévue pour recevoir un panneau photovoltaïque 2 et des moyens de liaison 5 reliant ladite embase 3 à ladite superstructure 4.  As can be seen in FIG. 1, such a support device 1 of photovoltaic panels 2 is free-standing at tilt and comprises a base 3 designed to serve as ballast, a flat superstructure 4 designed to receive a photovoltaic panel 2 and connecting means. 5 connecting said base 3 to said superstructure 4.
Concernant, l'embase 3, cette dernière est conformé sous la forme d' une infrastructure constitué en béton préfabriqué et est destinée à reposer sur le sol au travers moyens de piétement 6 s 'adaptant à la configuration du sol, notamment des sols de types accidentés ou non terrassés. On notera, que ce dispositif support 1 peut également être utilisé pour des toitures terrasses. Regarding the base 3, the latter is shaped in the form of an infrastructure made of prefabricated concrete and is intended to rest on the ground through means of base 6 which is adapted to the configuration of the ground, particularly soils of uneven or uneven types. It will be noted that this support device 1 can also be used for flat roofs.
Plus particulièrement, les moyens de piétement 6 sont disposés sur la face inférieure 7 de l'embase 3 et sont constitués par au moins trois pieds 8 réalisés préférentiellement en béton préfabriqué et agencés sur la face inférieure 7 de l'embase 3 pour augmenter l' autostabilité du dispositif 1.  More particularly, the base means 6 are arranged on the lower face 7 of the base 3 and are constituted by at least three feet 8 preferably made of precast concrete and arranged on the lower face 7 of the base 3 to increase the Autostability of the device 1.
Avantageusement, lesdits pieds 8 sont choisis dans une gamme de hauteur lors de la pose de manière à ce l'embase 3 épouse parfaitement le sol et permette au dispositif 1 une installation non intrusives les sols hétérogènes sur lesquels il peut venir reposer .  Advantageously, said legs 8 are chosen in a height range during installation so that the base 3 perfectly fits the ground and allows the device 1 a non-intrusive installation heterogeneous soils on which it can come to rest.
Selon le mode d'exécution préféré de l'invention, l'embase According to the preferred embodiment of the invention, the base
3 comporte une face supérieure 9 comportant une inclinaison déterminée et pré-calculée de sorte d'une part à décaler le centre de gravité 10 de l'embase 3 vers un bord supérieur 11 (ou bord d'attaque) de cette dernière par rapport au sol et, d' autre part à améliorer le centrage avant et le comportement dispositif 1 en fonction des efforts subis et, notamment, de forts vents . 3 comprises an upper face 9 having a predetermined inclination and pre-calculated so on the one hand to shift the center of gravity 10 of the base 3 to an upper edge 11 (or leading edge) of the latter relative to the and on the other hand to improve the front centering and the device 1 behavior according to the forces undergone and, in particular, strong winds.
De plus, ladite inclinaison déterminée de la face supérieure 9 de l'embase 3 permet avantageusement de procurer un effet de permettant de réduisant les efforts aérodynamiques sur les panneaux (tel un volet ou un « spoiler ») ainsi que l'écoulement de l'air au sein dudit dispositif 1.  In addition, said determined inclination of the upper face 9 of the base 3 advantageously provides an effect of reducing the aerodynamic forces on the panels (such as a flap or a "spoiler") and the flow of the air within said device 1.
Pour en revenir à la superstructure 4 , celle-ci se compose de deux longerons 12 s 'étendant longitudinalement par rapport à ladite embase 3.  To return to the superstructure 4, it consists of two longitudinal members 12 extending longitudinally with respect to said base 3.
Tel que visible sur la figure 2 , les longerons 12 comportent sur leur face supérieure 13 des lisses 14 transversaux sur lesquels viennent reposer le ou les panneaux photovoltaïques 2.  As can be seen in FIG. 2, the longitudinal members 12 have on their upper face 13 transverse rails 14 on which the photovoltaic panel (s) 2 rest.
A ce propos, on remarquera que lesdits longerons 12 comportent une inclinaison ce qui induit qu'ils comportent par rapport au sol un bord horizontal supérieur 15 (le plus haut) et un bord inférieur 16. In this regard, it will be noted that said longitudinal members 12 comprise an inclination which induces that they comprise by relative to the ground an upper horizontal edge 15 (the highest) and a lower edge 16.
De plus, les longerons 12 comportent un entraxe supérieur à la largeur de l'embase 3 de manière à ce que les moyens de liaison 5 viennent, d'une part, en emboîtement sur la face inférieure des longerons 12 et, d'autre part viennent se fixer sur les flancs de l'embase 3.  In addition, the longitudinal members 12 have a spacing greater than the width of the base 3 so that the connecting means 5 are, on the one hand, interlocked on the underside of the longitudinal members 12 and on the other hand are fixed on the flanks of the base 3.
Préférentiellement , lesdits moyens de liaison 5 sont constitués par des montants 17 qui sont, d'une part, maintenus à leur extrémité basse 18 contre les flancs de l'embase 3 par douilles idéalement installées en préfabrication et, d'autre part, à leur extrémité haute 19 emboîtés dans des cavités que comportent les longerons 12. L'installation des montants le long des flancs permet de réaliser un encastrement de la demie ferme et ainsi de s'affranchir de contreventements  Preferably, said connecting means 5 are constituted by uprights 17 which are, on the one hand, held at their lower end 18 against the flanks of the base 3 by sockets ideally installed in prefabrication and, on the other hand, their high end 19 nested in cavities that include the longitudinal members 12. The installation of the amounts along the sides allows for a recess of the half farm and thus to overcome the braces
A ce propos, on notera que ce sont les montants 17 qui maintiennent ladite superstructure 4 selon une inclinaison particulière de sorte que ladite superstructure est un positionnement du centre de poussée 20 le plus loin possible de son bord inférieur 15 (ou bord de fuite) .  In this respect, it will be noted that it is the uprights 17 which hold said superstructure 4 in a particular inclination so that said superstructure is a positioning of the thrust center 20 as far as possible from its lower edge 15 (or trailing edge).
Selon l'invention, le centre de poussée 20 de la superstructure 4, est le plus loin possible de son bord inférieur 16 tout en étant en arrière du centre de gravité 10 de l'embase 3 par rapport au bord supérieur 15 de la superstructure 4.  According to the invention, the thrust center 20 of the superstructure 4 is as far as possible from its lower edge 16 while being behind the center of gravity 10 of the base 3 relative to the upper edge 15 of the superstructure 4 .
Avantageusement, cette configuration permet d'une part une répartition harmonieuse de tous les efforts subis par le dispositif support 1 et, d'autre part de réduire l'effet venturi et donc les efforts subis par le dispositif 1 et les panneaux photovoltaïques 2. En particulier, les effets venturi les plus violents sont déplacés hors du dispositif de support 1 de panneaux de photovoltaïques 2.  Advantageously, this configuration allows on the one hand a harmonious distribution of all the forces experienced by the support device 1 and, on the other hand to reduce the venturi effect and therefore the forces experienced by the device 1 and the photovoltaic panels 2. In particular, the most violent venturi effects are moved out of the photovoltaic panel support device 1.
Selon un mode d'exécution particulier de l'invention, les montants 17 constituent un treillis de poutres augmentant la résistance du dispositif 1 et équilibrant les charges entre les différentes fixations de l'embase 3 et de la superstructure 4. De manière avantageuse, le dispositif de support 1 est conçu apte, à la fin de la période d'exploitation de la centrale photovoltaïque, à être démantelée complètement pour permettre au site d' installation de retrouver son état d' origine . According to a particular embodiment of the invention, the uprights 17 constitute a trellis of beams increasing the resistance of the device 1 and balancing the loads between the different fasteners of the base 3 and the superstructure 4. Advantageously, the support device 1 is designed able, at the end of the operating period of the photovoltaic power plant, to be dismantled completely to allow the installation site to return to its original state.
Notamment, l'embase 3 est prévue pour être recyclable soit en éléments de voierie, par exemple voies d'accès agricoles, ou alors pour être recyclées par concassage.  In particular, the base 3 is intended to be recyclable either in road elements, for example agricultural access roads, or to be recycled by crushing.
Un tel dispositif permet avantageusement d' être autostable au basculement dans des zones cycloniques et de permettre sont installation et son démantèlement aisés sur tous types de sols.  Such a device advantageously makes it possible to be freeze-tilting in cyclonic zones and to allow easy installation and dismantling on all types of soils.
Bien entendu, l'invention n'est pas limitée aux exemples illustrés et décrits précédemment qui peuvent présenter des variantes et modifications sans pour autant sortir du cadre de 1 ' invention .  Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
