Description

Description Title of the invention: Photovoltaic panel device and photovoltaic energy production installation comprising at least one such device1 [The present invention relates to a photovoltaic panel device, as well as a shade-type photovoltaic energy production installation comprising at least one such device. 2 The invention relates to the field of photovoltaic solar energy production and relates, more particularly, to a photovoltaic panel device capable of being extended in height so as to free up the space underneath for various uses. Thus, such a photovoltaic panel device, according to the invention, will find an application particularly in the field of agrivoltaics. 3 An agrivoltaic installation delimiting a closed enclosure intended for livestock is known, for example, from document FR 3 110 325.It comprises a series of tables aligned along a general longitudinal axis, preferably between 5 and 15 tables, having a ridge height of 3 to 10 m. Two adjacent tables are separated by a ground width of 6 to 11 m. The supporting structure of each table comprises equidistant posts supporting a framework formed of inclined gantries and horizontal gantries defining an upper inclined plane covered with fixed photovoltaic panels of identical orientation. 4 Also known, from document FR 3 099 861, is a system of photovoltaic panels and a photovoltaic power plant comprising such a system. This essentially comprises several pairs of guyed posts aligned in a longitudinal direction. At their upper end and between the two posts of a pair of posts, a cable is stretched transversely.Support tubes are fixed to the cables of two successive pairs of poles in rotation, parallel, equidistant and in a longitudinal direction. Photovoltaic panels are attached to these support tubes. These are attached in pairs radially along these support tubes. These photovoltaic panels extend, substantially, in the same plane and can be oriented by rotation of the support tube from which they are attached. integral. In this regard, at their ends the support tubes are made integral with the cables by fixing means comprising a 1 re part suitable for being fixed to the cable and a 2 epart adapted to be assembled so as to be mobile in rotation relative to said first part. 5 Similarly, documents WO 2018 / 193 390 and WO 2022 / 029600 disclose a photovoltaic energy production installation for agricultural applications, consisting of several longitudinal rows of equidistant poles, these rows extending parallel to each other. Each row of poles supports a rotating support tube from which photovoltaic panels extend radially, themselves pivoting around an axis perpendicular to this support tube. In the manner of a mesh, cables transversely connect the poles of the different rows. Furthermore, the poles at the periphery of the installation are guyed.6 In each of these solutions described in the state-of-the-art documents cited above, the photovoltaic panels are systematically secured to a tube or rigid profiles extending between two support posts or between two carrying cables. Such tubes or rigid profiles necessarily have a specific section to avoid their permanent deformation under the simple weight of the photovoltaic panels they support or the stresses imposed by these photovoltaic panels under the effect of the wind, for example. Also, the assembly, tubes or rigid profiles plus photovoltaic panels, represents a significant weight above the support structures allowing the photovoltaic panels to be kept high, several meters above the ground. 7 Indeed, the interest of such photovoltaic panel systems lies in the possibility of exploiting the ground surface for livestock farming, or even agricultural crops, or other purposes.8 It is obviously understood that this weight to be supported has consequences on the characteristics of the support structures which, not only, must be dimensioned accordingly, but, in addition, require significant civil engineering work to ensure their anchoring to the ground. 9 Also known from document ES2946707 is a photovoltaic panel device comprising two support posts anchored to the ground and guyed, between which photovoltaic panels are extended. More particularly, between these posts extends a central filiform element, which may take the form of a cable, but will preferably be defined by a bar due to the stresses it is subjected to as is apparent from paragraph

[0095] of this document. This central filiform element is intended to support the majority of the weight of the photovoltaic panels, which also pivot around this central filiform element. On either side of the photovoltaic panels, at the ends and on the central filiform element, there are also pivotally mounted lateral profiles between which are extended, again, filiform elements serving as support for the photovoltaic panels at the external end edges, on either side of their pivot axis. Actuating means are provided to rotate these lateral profiles around the central filiform element and thus ensure the pivoting of the photovoltaic panels.These external filiform elements can also be defined by cables, but the latter are in no way able to contribute to transferring the load of the photovoltaic panels onto the supporting posts, due to the pivoting mounting of the lateral profiles on the central filiform element and not on said posts. At most, these external filiform elements contribute to keeping the photovoltaic panels in the same alignment. 0 With regard to the actuation means described in this document ES2946707, they comprise two pulleys mounted on supports fixed to the ground, a taut rope which extends in a loop between the two pulleys, a motor configured to cause the rotation of a pulley and the movement of the rope.These actuating means also comprise two slings, each of which has one end secured to the rope and an opposite end fixed to one of the ends of a lateral profile, so that the movement of the rope by driving one of the ends of the slings causes the rotation of said lateral profile around the central filiform element, ensuring the pivoting of the photovoltaic panels in one direction or the other depending on the direction of movement communicated to the rope by the motor. 1 It goes without saying that this type of photovoltaic panel device is intended to be extended at a low height above the ground, a useful height for rotating the photovoltaic panels and facilitating the installation of this device on uneven ground, if only because of the configuration of the actuation means and the total weight of the photovoltaic panels transferred to a single thread-like element, in this case a cable stretched between two support posts. In reality, this weight of the panels is negligible compared to the stresses that the wind acting on these panels, like sails, can apply. Also, such a photovoltaic panel device according to the state of the art will necessarily have to be sized accordingly and limited to a very small number of photovoltaic panels.2 The invention aims to provide a photovoltaic panel device of simple design, implementing means which make it possible to considerably reduce the weight thereof, while providing numerous advantages in terms of mechanical strength. 3 Thus, it is within the framework of a first inventive approach that means of supporting the photovoltaic panels have been devised in the form of several cables capable of jointly supporting the weight of the supported photovoltaic panels and transferring it to high support structures for any exploitation of the ground beneath these photovoltaic panels. 4 In this same inventive approach, the support structures have been designed to be flexible with respect to their anchoring to the ground, providing the assembly with very high resistance under the action of constraints generated by meteorological conditions, in particular wind.5 Thus the invention relates to a photovoltaic panel device comprising at least two guyed support structures between which photovoltaic panel support means are extended, characterized in that a support structure comprises at least one support post and a burial or sealing pile, the latter being surmounted by a base which is made integral by connecting means. articulated the lower end of the support post, the support means being defined by at least two cables stretched parallel and spaced apart from each other between two support consoles, each of which surmounts the support post of a support structure by being fixed to this support post, on these cables being attached the photovoltaic panels. 6 According to the invention, a support console comprises, on the one hand, a fixing base through which it is attached to a support structure and, on the other hand, a crosspiece mounted freely in rotation at its center on the fixing base by means of mounting in rotation about an axis parallel to the cables, this crosspiece extending substantially perpendicular to these cables, one of the ends of which is connected to said crosspiece. 7 Advantageously, at least one guy is fixed to the fixing base of a support console (8, 9) surmounting a support structure.8 According to another feature of the invention, each cable is subjected to a prestressing tension. 9 The invention also relates to a shade-type photovoltaic energy production installation, comprising at least one row composed of at least one photovoltaic panel device according to the invention. 0 Advantageously, this installation comprises at least two photovoltaic panel devices arranged parallel to each other and / or one of which constitutes the extension of the other. 1 The advantages arising from the present invention consist, essentially, in that the photovoltaic panel device according to the invention is of simple and lightweight design resulting in easy installation conditions, without any significant real constraint, of the civil engineering type, above a ground surface left free for any type of use, in particular for agricultural operations, whether livestock farming or cultivation.2 In addition, thus stretched between the cable-stayed support structures, the cables and the support consoles at their ends, design a beam. cables capable of supporting the photovoltaic panels in a flat manner, while limiting the chain effect. 3 Other objects advantageous to the present invention will appear during the description which follows relating to different embodiments illustrated in the figures of the appended drawings in which: 4 [Fig.1] Figure 1 is a schematic representation in perspective of an exemplary embodiment of a photovoltaic panel device according to the invention;

This comprises at least two guyed support structures, one upstream 2 and one downstream 3, which, as illustrated in the figures, can take the form of posts, depending on the case, single or double in the shape of an inverted V, as shown in Figures 1 and 2. In short, a support structure 2, 3 is formed, in this case, by two posts 2a, 2b; 3a, 3b spaced apart at their lower end at which they are anchored to the ground and meet at their upper end 4. Obviously, such support structures 2, 3 can take many other forms of embodiment, without departing, however, from the object of the present invention. 5 The height of these support structures 2, 3 will be chosen according to the conditions of installation and application of the photovoltaic panel device 1.Likewise, the distance between these support structures 2, 3 of a photovoltaic panel device 1 is variable. For example, it can be 10 meters, or even less, up to 25 meters, or even more. 6 Between these two support structures, upstream 2 and downstream 3, are extended support means 5 for photovoltaic panels 6. 7 According to the invention, these support means 5 are defined by at least two cables 7, 7a, 7b, 7c stretched, parallel to each other and spaced apart from each other, between two support consoles 8, 9 each of which surmounts a support structure 2, 3 by being made integral with the latter. 8 According to another feature of the invention, these support consoles 8, 9 comprise, on the one hand, a fixing base 30 through which they are attached to these support structures 2, 3 and, on the other hand, a crosspiece 12, in particular illustrated in more detail in Figure 3.This crosspiece 12 is made integral, preferably in its center, with the fixing base 30, this by means of rotational mounting means 15 around an axis A parallel to the cables 7, 7a, 7b, 7c. 9 Between these crosspieces 12, thus firmly mounted in rotation on their bases 30, moreover fixedly attached to the support structures. 2, 3, the cables 7, 7a, 7b, 7c are tensioned so that it is possible to subject them to rotation around the axis A. 0 According to the invention, each cable 7, 7a, 7b, 7c is subjected to a prestressing tension greater than 2t (two tons), preferably between 3t and 5t (three tons and five tons), advantageously of the order of 4t (four tons). Advantageously, the cables 7, 7a, 7b, 7c and crosspieces 12 are dimensioned to withstand up to at least 11t of tension, for example induced by wind exposure of the photovoltaic panels 6. 1 This tensioning can be obtained by any suitable means, for example, tensioning means associated with each of the cables and / or through at least one of the crosspieces 12 to which they are made integral at their ends. In particular, the axial position of this crosspiece 12 can be provided to be adjustable by suitable means, for example associated with the rotational mounting means 15.2 Preferably, at least one tensioning guy wire 31, 32 is fixed to the upper end portion of at least one of the support structures 2, 3. This or these guy wires 31, 32 can, depending on the case, generate the tension in the cables and / or contribute to maintaining it. 3 Advantageously, at least one guy wire 31 is fixed to the fixing base 30 of a support console 8, 9 surmounting a support structure 2, 3. In this way this guy wire 31 directly absorbs the tension forces applied to this support console 8, 9 by the prestressed cables 7, 7a, 7b, 7c. 4 To prevent the support structures from giving way, or even breaking in the case of use of wooden posts for example, this under the influence:. - the tension exerted by the cables 7, 7a, 7b, 7c through the support consoles 8, 9 (tension which can be of the order of 20 tonnes); - and / or the additional constraints generated by the wind exposure of the photovoltaic panels 6 supported by the cables 7, 7a, 7b, 7c; - and / or the forces applied by the guy wire(s) 31, 32 on these support structures 2, 3; it is provided, according to the invention, that the support structures 2, 3 consist of at least one support post 33 and a burial or sealing pile 34, the latter being surmounted by a base 35 to which the lower end 37 of the support post 33 is made integral by articulated connection means 36. 5 This design has the advantage of providing play in the position of the support structures 2, 3 to prevent them from breaking in the event of excessive wind, frost or other reason resulting in an increase in the tension on the cables. 6 Furthermore, by thus avoiding subjecting these support structures 2, 3 to excessive forces, in particular bending, their design can be lightened, for example by using metal profiles or wooden posts of smaller section. This allows for reduced anchoring to the ground, using smaller foundations and being less intrusive for the soil.7 As for the articulated connection means, they can take different forms of embodiment, for example of the type illustrated in Figure 5 knowing that they could also be defined substantially by one or more silentblocs of adapted section. However, a mechanical articulation solution, implementing an axis passing through yokes equipping the lower end 37 of the support post 33 and the base 35 of the pile 34 is preferred. 8 If we consider that the support structures 2, 3 extend substantially vertically from the ground and that the cables 7, 7a, 7b, 7c are stretched substantially horizontally above the ground, we can estimate that the crosspieces 12 of the support consoles 8, 9 are mounted in rotation on the support structures 2, 3 around an axis A substantially perpendicular to the latter and substantially parallel to the axis of the cables 7, 7a, 7b, 7c.9 The photovoltaic panels 6, 6a are fixed to the cables 7, 7a, 7b, 7c using suitable fixing means 10 schematically shown in Figure 10. Preferably, the photovoltaic panels 6, 6a extend in a transverse arrangement, with or without spacing, between the cables 7, 7a, 7b, 7c. 0 It should be noted that such photovoltaic panels 6, 6a can be rigid or flexible. 1 Depending on the number of cables 7, 7a, 7b, 7c stretched between the support brackets 8, 9 and their spacing, one or more photovoltaic panels 6, 6a can be fixed transversely on these cables 7, 7a, 7b, 7c as visible as examples in figures 1, 2, 6 and 7. 2 Thus, in figures 1 and 2 illustrating an exemplary embodiment, three cables 7, 7a, 7b are stretched between the crosspieces 12 of the support brackets 8, 9, above these cables being fixed, transversely and in pairs 11, the photovoltaic panels 6, 6a. The two photovoltaic panels 6, 6a extend transversely in the extension of one another, being joined at the height of the central cable 7a on which they are fixed jointly.3 In the embodiment corresponding to Figure 6, the photovoltaic panels 6, 6a extend, again, transversely and in the extension of one another above the cables, here four in number, 7, 7a, 7b, 7c stretched between the crosspieces 12 of the support consoles 8, 9. Each panel 6; 6a of a pair of panels 11 is individually fixed on two cables respectively 7, 7a; 7b, 7c. 4 If, in these embodiments corresponding to these figures 1, 2 and 6, the photovoltaic panels 6, 6a or pair of panels 11 are fixed along the cables 7, 7a, 7b, 7c with systematically a spacing E between them, they can obviously be fixed in a contiguous or quasi-contiguous manner along these cables 7, 7a, 7b, 7c, just as certain panels can be fixed closer to each other, when other photovoltaic panels respect a greater spacing between them along these cables 7, 7a, 7b, 7c.5 The advantage of such a spacing E consists in allowing solar radiation to diffuse between these photovoltaic panels 6, 6a to encourage possible ground crops, for example. 6 The exemplary embodiment corresponding to figure 7 differs from the previous embodiments in that the photovoltaic panels 6, 6a are. fixed in a staggered pattern above the cables 7, 7a, 7b, here three in number, an arrangement which can be chosen to facilitate the individual fixing of each of the photovoltaic panels 6, 6a on these cables 7, 7a, 7b, but also to create this spacing E promoting the passage of solar radiation. 7 According to yet another embodiment not illustrated, transversely above the cables 7, 7a, 7b, 7c, at least two in number, rigid support structures can be fixed on which at least two photovoltaic panels are mounted in a fixed manner. Such a rigid support structure can take the form of at least two metal or synthetic material profiles on which these photovoltaic panels are fixed by designing a table of photovoltaic panels which is added to the cables 7, 7a, 7b, 7c.8 The support consoles 8, 9 essentially comprise a crosspiece 12 extending substantially perpendicular to the cables 7, 7a, 7b, 7c and to which one of the ends 13, 14 of these cables 7, 7a, 7b, 7c is connected. Such a crosspiece 12 is mounted using the rotational mounting means 15 on a fixing base 30 illustrated in the form of a bracket in FIG. 4. In particular, on the vertical wing 39 of this fixing base 30 can be fixed an axis section 40 on which is fitted and axially fixed an annular bearing 41 designed to be secured to the center of a crosspiece 12. 9 At least one 8 of said support consoles 8, 9 is equipped with drive means 16, preferably motorized, to control controlled rotation around the axis A of the associated crosspiece 12 and, thus, ensure the pivoting of the latter. This makes it possible to orient in inclination the photovoltaic panels 6, 6a supported by the cables 7, 7a, 7b, 7c.The crosspiece 12 of the opposite support console 9 is, depending on the case, mounted freely in rotation by means of the bearing 15 on the support structure 3 concerned, just as this support console 9 can also receive similar drive means 16, preferably operating in synchronization with those 16 acting on the crosspiece 12 of the opposite support console 8. 0 In figure 4, these drive means 16 are represented in the form of a motor M designed to act on the annular bearing 41 mounted on the axis A and,. thus controls the pivoting of said crosspiece 12. For example, this annular bearing can be equipped with a drive ring (not visible) which houses an annular casing 42 and on which this motor M acts. 1 It will be noted in figures 3 and 4 that a crosspiece 12 is profiled in relation to the stresses to which it can be subjected and the consequent section of the annular bearing 41 contributing to its rotational mounting and its axial maintenance on the axis section 40. It should be recalled in this regard that through these rotational mounting means defined by this bearing are transmitted the axial forces generated by the prestressing of the cables 7, 7a, 7b, 7c.2 Thus, the specific design of the crosspiece 12 preferably has the function of distributing linear loads between the axis A of rotation of this crosspiece 12 and its ends where the cables 7, 7c are fixed, this for a concentration of forces from these cables 7, 7c towards the axis A, then the support structure 2, 3. 3 Note that the motor M of such drive means 16 is of the low rotation speed and high gear reduction type for very low speed drive, it being recalled that the adjustment of the position of the photovoltaic panels 6 must take place according to the position of the solar radiation. 4 This motor M can be connected wired or wirelessly, by internet, wifi, Bluetooth or other to a control unit which is able to manage the orientation of the photovoltaic panels.5 This orientation can thus be ensured according to the position of the sun and the incident angle of the solar radiation and / or the need for photovoltaic energy production and / or the activity to be maintained under a photovoltaic energy production installation according to the invention. 6 As an example to which the invention is in no way limited, by an adapted orientation of the photovoltaic panels it is possible to promote the passage of solar radiation to irrigate the crops below at certain times. of the day and on the contrary, protect these crops at other times of the day so as to avoid them drying out. 0067 As seen in figures 1 and 2, the fixing base 30 of a support console 8, 9 can surmount the upper end 4 of a double post 2a, 2b in an inverted V defining a support structure 2, 3, the invention obviously not being limited to such an embodiment. 0068 The invention also relates to a shade-type photovoltaic energy production installation 17, comprising at least one row 18, 18a composed of at least one photovoltaic panel device 1, 1a according to the invention. 0069 Advantageously, a row 18, 18a comprises substantially in the same longitudinal alignment several photovoltaic panel devices 1, 1a. 0070 Preferably, such an installation 17 comprises several substantially parallel rows 18, 18a of several photovoltaic panel devices 1, 1a, as visible in figures 8 and 9. Advantageously, in such a design, the rows 18, 18a are connected to each other transversely at the height of their support structures by transverse consolidation elements 38. These can be defined by cables or, preferably, rigid profiles. 0071 According to a possible embodiment shown schematically in Figure 8, two photovoltaic panel devices 1, 1a following one another can share, in this case, the support structure 32, at the height of their junction. In short, this defines both the downstream support structure 3 of an upstream photovoltaic panel device 1 and the upstream support structure 2 of a downstream photovoltaic panel device 1a. 0072 On this support structure 32 can be mounted the downstream support console 9 of the upstream device 1 and the upstream support console 8 of the downstream device 1a. These support consoles 9, 8 can share a double fixing base 30, for example U-shaped, receiving in rotation, around an axis A extending in a first direction, the crosspiece 12 of the downstream support console 9 of the upstream device 1 and around an axis A, extending in a second direction opposite that 12 of the upstream support console 8 of the downstream device 1a. 0073 This shared bearing 15 may be associated with drive means 16, preferably motorized, to control rotation around the axis A of each of the crosspieces 12 of said downstream 9 and upstream 8 support consoles for the simultaneous orientation of the photovoltaic panels 6; 6a of the upstream device 1 and those of the downstream device 1a. 0074 According to another variant that figure 9 wishes to represent, two photovoltaic panel devices 1, 1a following one another can share at the height of their junction a support console 98 comprising a crosspiece 12 to which are fixed the downstream ends 14 of the cables 7, 7a, 7b, 7c of the upstream device 1 and the upstream ends 13 of the cables 7, 7a, 7b, 7c of the downstream device 1a. 0075 Such a crosspiece 12 is then pivotally mounted around a horizontal axis A by means of a base 15 of suitable configuration surmounting the support structure 32, shared between the upstream device 1 and the downstream device 1a. This suitable base 15 can, again, be associated with drive means 16, preferably motorized, to control rotation around the axis A of this crosspiece 12 for the simultaneous orientation of the photovoltaic panels 6; 6a of the upstream device 1 and those of the downstream device 1a. 0076 In short, this support console 98 defined, both the downstream console 9 of the upstream device 1 and the upstream console 8 of the downstream device 1 a. 0077 According to the invention, each photovoltaic panel device 1, 1a can have its own drive means 16, just as single drive means 16 can contribute to the rotational control of the photovoltaic panels of two or more photovoltaic panel devices 1, 1a of a row 18; 18a of an installation 17. 0078 At least the support structures 2, 3 at the ends of each row 18, 18a of photovoltaic panel devices 1, 1a are guyed. Advantageously, all the support structures 8, 9 at the periphery of an installation 17 are guyed. 0079 Figure 10 schematically illustrates an embodiment of fixing means 10 of a photovoltaic panel 6, 6a on cables 7, 7a, 7b. Such fixing means 10 are in the form of cable clamps 19 fitted on one of the sides or at the periphery of a photovoltaic panel 6, 6a, or even a table of photovoltaic panels. Advantageously, these cable clamps 19 are mounted in a pivoting and / or translationally movable manner under a photovoltaic panel 6, 6a or a table of photovoltaic panels. 0080 The invention makes it possible to solve the technical problem of tensioning and rotating a set of photovoltaic panels 6, 6a fixed on suspended cables 7, 7a, 7b, 7c by doing away with any intermediate rigid support. The photovoltaic panels 6, 6a are installed at height on tensioned cables 7, 7a, 7b, 7c acting like a beam, limiting the chain effect and the mechanical stresses which can result from it during rotational movements. 0081 The invention thus makes it possible to reduce ground anchoring and related earthworks. It also opens up the possibility of being installed on existing crops while limiting their damage. 0082 The main field of application of an installation according to the invention is its installation on agricultural land. It can be implemented above existing crops, making it possible to protect and improve the yield of these crops, while producing electricity. 0083 The invention can also be deployed as a shade structure on artificial surfaces such as parking lots or outdoor storage areas. |
