The circular and continuous element comprises a rigid and resistant structure (27) filled with synthetic foam. A propeller of turbines is connected to the carrier element to slow down and/or stop the rotation movement of the carrier element. The carrier element is located against a vertical guide (30) in an interior side of a circle for guiding the rotational movement on the structure in a horizontal plane.

Description

SUPPORTS AQUATIQUES ET TERRESTRES DES PANNEAUX SOLAIRES ET AMELIORATION DE LEUR RENDEMENT les supports de panneaux solaires ont pour but, durant les heures d'ensoleillement d'un lieu, d'avoir toujours les panneaux solaires ,appelés ci-après P, perpendiculaires aux rayons du soleil. La technique antérieure définit déjà des solutions aquatiques et terrestres appelées suiveurs ou trackers, flottants sur l'eau ou fixés au sol, ou posés seulement au sol. La présente invention a pour but de modifier et/ou perfectionner certaines de ces différentes solutions techniques en proposant des dispositions constructives qui les améliorent, par simplification et/ou par utilisation de phénomènes naturels négligés jusqu'ici.AQUATIC AND TERRESTRIAL SUPPORTS OF SOLAR PANELS AND IMPROVING THEIR EFFICIENCY solar panel supports are intended, during the hours of sunshine of a place, to always have the solar panels, hereinafter referred to as P, perpendicular to the radii of the solar panels. Sun. The prior art already defines aquatic and terrestrial solutions called trackers or trackers, floating on the water or fixed to the ground, or placed only on the ground. The present invention aims to modify and / or improve some of these different technical solutions by proposing constructive provisions that improve them, for simplification and / or use of natural phenomena neglected so far.

En effet la présente invention amène des améliorations dans le rendement des suiveurs solaires en utilisant le phénomène de réflexion totale des rayons solaires sur un plan d'eau et/ou sur une surface réfléchissante. La technique antérieure, si l'on est en site terrestre, fig J prévoit par exemple des tubes 1 rotatifs sur lesquels on fixe des panneaux solaires P ; ces tubes 1 sont eux -même posés sur des supports 2 qui sont appuyés sur des corps flottants 3 .Ces corps flottants 3 sont dans l'eau 5 ou tout autre liquide contenu dans une goulotte circulaire 4, cette goulotte 4 étant posée au sol 6. La présente invention propose d'améliorer le rendement de cette disposition en rendant le sol support 6 réfléchissant fig 2, par exemple en y posant des plaques d'aluminium au fort pouvoir de réverbération, et ce sur la longueur des tubes 1 et sur une largeur 7, soit sur une surface 8. Cette surface 8 sera déterminée selon les valeurs données aux longueurs 9 entraxe des tubes 1 fig 2, 12 hauteur de l'axe des tubes 1 au dessus du plan d'eau fig 3, et 13 hauteur libre en dessous des panneaux P lorsqu'ils sont en position verticale fig 3. On étudiera la meilleure dimension à donner à l'entraxe 9 entre 2 tubes 1 et la meilleure hauteur 12 qui permette à l'espace 13 de laisser passer les rayons solaires sous les panneaux P Une simple épure peut donner les valeurs recherchées.Indeed, the present invention brings improvements in the efficiency of solar trackers by using the phenomenon of total reflection of solar rays on a water plane and / or on a reflecting surface. The prior art, if it is a terrestrial site, fig J provides for example 1 rotating tubes on which solar panels P are fixed; these tubes 1 are themselves placed on supports 2 which are supported on floating bodies 3. These floating bodies 3 are in water 5 or any other liquid contained in a circular chute 4, this chute 4 being placed on the ground 6 The present invention proposes to improve the efficiency of this arrangement by making the reflecting support floor 6 Fig 2, for example by placing aluminum plates with high reverberation power, and this over the length of the tubes 1 and on a width 7, or on a surface 8. This surface 8 will be determined according to the values given to the lengths 9 spacing of the tubes 1 fig 2, 12 height of the axis of the tubes 1 above the water level fig 3, and 13 height free below the panels P when in vertical position fig 3. We will study the best dimension to give the spacing 9 between 2 tubes 1 and the best height 12 which allows the space 13 to let through the sunlight under the panels P A simple outline can give the desired values.

Ce phénomène de réflexion totale fig 3, naturel ou provoqué, double le rendement des surfaces déjà directement au soleil, et/ou activent les surfaces provisoirement et/ou partiellement à l'ombre portée d'un panneau P voisin tant que l'inclinaison des rayons solaires est inférieure à 45°.This phenomenon of total reflection fig 3, natural or provoked, doubles the efficiency of the surfaces already directly in the sun, and / or activates the surfaces provisionally and / or partially to the shadow of a neighboring P-panel as long as the inclination of solar rays is less than 45 °.

Car le panneau P incliné à 45° est parallèle au rayon solaire réfléchi lui aussi à 45°, puisque l'angle d'incidence est égal à l'angle de réflexion. -2 - Mais de 0 à 450 d'inclinaison, c'est-à-dire dès le lever du soleil pendant 4 heures environ sous la latitude de la France, et avant le coucher du soleil, aussi pendant 4 heures environ, la bonification générale de la production électrique est très importante . A titre d'exemple, en France par exemple, la hauteur du soleil sur l'horizon est inférieure ou égale à 45° durant 6 mois de l'année, et les 6 autres mois elle est inférieure ou égale à 45° près de 8 heures par jour. D'où l'intérêt d'améliorer le rendement des panneaux P en utilisant le phénomène de réflexion totale. Des panneaux solaires Pfig 4,5 ,6 montés sur des suiveurs 14 qui seraient entourés d'eau 15, fondés sur une bouée immobilisée 16 ou un pieu 17 fixé au fond du plan d'eau 18, auront ainsi une importante augmentation de leur production. Une technique antérieure fig 7,8 prévoit que les supports 2 qui tiennent les tubes 1 reposent sur un un plan d'eau 19 grâce à des cercles flottants concentriques 20 et 21 Le cercle extérieur 20 est fixe, solidaire de câbles 22 et de tirants 23 tendus entre des points fixes 24 et supportés éventuellement par des bouées 25. La présente inventionfig9,10 propose une autre version : elle comporte un seul élément circulaire flottant 26 fig 13 ,immobilisé sur un plan d'eau 19, rendu rigide par une structure résistante 27 figlOet insubmersible par un remplissage de son corps en matière légère 28 et/ou par un caisson étanche de même volume. Cette structure 27 fig10, 13 a une partie supérieure 29 planefig9, 10,13 suffisamment résistante pour supporter le poids des éléments 2 qui s'appuient sur cette surface 29 et supportent eux même les tubes 1 et les panneaux P .Because the panel P inclined at 45 ° is parallel to the solar ray also reflected at 45 °, since the angle of incidence is equal to the angle of reflection. -2 - But from 0 to 450 tilt, that is to say at sunrise for about 4 hours in the latitude of France, and before sunset, also for about 4 hours, the bonus The general production of electricity is very important. For example, in France for example, the height of the sun on the horizon is less than or equal to 45 ° during 6 months of the year, and the other 6 months it is less than or equal to 45 ° close to 8 hours per day. Hence the interest of improving the efficiency of the panels P by using the phenomenon of total reflection. Pfig solar panels 4,5, 6 mounted on followers 14 which would be surrounded by water 15, based on an immobilized buoy 16 or a pile 17 fixed to the bottom of the body of water 18, will thus have a significant increase in their production. . A prior art fig 7,8 provides that the supports 2 which hold the tubes 1 rest on a body of water 19 through concentric floating circles 20 and 21 The outer circle 20 is fixed, secured to cables 22 and tie rods 23 stretched between fixed points 24 and possibly supported by buoys 25. The present invention fig9,10 proposes another version: it comprises a single floating circular element 26 fig 13, immobilized on a water plane 19, made rigid by a resistant structure 27 figlOet unsubmersible by a filling of its body light material 28 and / or by a watertight box of the same volume. This structure 27 fig10, 13 has an upper portion 29 planfig9, 10,13 sufficiently strong to support the weight of the elements 2 which rest on this surface 29 and themselves support the tubes 1 and P panels.

Cette structure 27 fig 13 peut être construite par morceaux en usine et assemblée pour former la structure 26 sur son lieu d'utilisation. Des roues 34 fig10 portant le ou les éléments 2 s'appuient sur la surface 29 La surface 29 est solidaire d'un guide vertical 30 fig 9,10 ,13 circulaire et continu, fer plat courbé par exemple.This structure 27 fig 13 can be built in pieces at the factory and assembled to form the structure 26 at its place of use. Wheels 34 fig10 carrying the element or elements 2 rest on the surface 29 The surface 29 is integral with a vertical guide 30 fig 9,10, 13 circular and continuous, curved flat iron for example.

La rotation du ou des éléments 2 est centrée sur le centre 31 du cercle formé par l'élément 26. S'il existe 2 ou plusieurs éléments 2 leur position entre eux sera rigidifiée par des tirants 32 fig 9 de telle sorte que les éléments 2 tournent centrés sur le point 31 Des guides 33 fig 9,11 fixés sur le ou les éléments 2, côté intérieur au cercle formé par le guide 30, dirigent le ou les éléments 2 dans leur mouvement de rotation ; -3- Ce mouvement est provoqué, dans un sens ou dans l'autre, par une ou des turbines ou moteurs à hélice 35 ou tout autre système équivalent ;ces éléments 35 sont fixés sur 2 par des montants ou flasques 36 fig10,11 ,12 sur le côté intérieur du cercle formé par l'élément 26, de manière à ne pas être gênés dans leur propulsion par les câbles 22 qui stabilisent l'élément 26 fig10.The rotation of the element or elements 2 is centered on the center 31 of the circle formed by the element 26. If there are 2 or more elements 2 their position between them will be stiffened by tie rods 32 fig 9 so that the elements 2 turn centered on the point 31 Guides 33 Fig 9,11 attached to the element or elements 2, inner side to the circle formed by the guide 30, direct the element or elements 2 in their rotational movement; This movement is caused, in one direction or the other, by one or more turbines or propeller motors 35 or any other equivalent system, these elements 35 are fixed on 2 by uprights or flanges 36 FIG. 12 on the inner side of the circle formed by the element 26, so as not to be hindered in their propulsion by the cables 22 which stabilize the element 26 fig10.

La poussée des éléments 35 est tangentielle à l'élément circulaire 26 ; la longueur des montants ou flasques 36 doit assurer aux éléments 35 d'être toujours sous le plan d'eau 19 fig 10,12 Un ou des vérins 37 suspendus à ou aux éléments 2, appliquent un patin ou similaire sur le guide vertical 30, et servent de freins au mouvement de rotation des éléments 2 fig 11,12 Les vérins 37, les guides 33, les roues 34 sont donc tous reliés à la ou aux parties inférieures du ou des éléments 2 et surplombent la surface plane 29 de ce ou ces éléments 2. La largeur 38 fig11,13 de cette surface circulaire plane 29 est dimensionnée en conséquence ; il en sera de même de la largeur 39 de l'élément 2The thrust of the elements 35 is tangential to the circular element 26; the length of the uprights or flanges 36 must ensure that the elements 35 are always under the water 19 fig 10,12 One or more cylinders 37 suspended to or to the elements 2, apply a pad or the like on the vertical guide 30, and serve as brakes to the rotational movement of the elements 2 fig 11,12 The cylinders 37, the guides 33, the wheels 34 are therefore all connected to the lower part or parts of the element or elements 2 and overlie the flat surface 29 of this or these elements 2. The width 38 fig11,13 of this flat circular surface 29 is dimensioned accordingly; it will be the same of the width 39 of the element 2
