Such devices, which perform a pursuit for maximizing the energy produced, are complex devices that are often associated with technologies that concentrate solar radiation to maximize thermal energy generation. electric, or other ...

In some cases, the panels are orientable along a single axis. In other cases, they are orientable along two axes. In view of the above, a problem to be solved by the object of the invention is to provide a solar panel device, which can be installed not only on the ground, but also on a frame or integrated into a frame, in particular, but not exclusively, in collective or residential housing. The proposed solution of the invention to this problem relates to a solar panel device comprising a fixed anchoring support, characterized in that it further comprises a movable panel support carrying at least one solar panel, at least three cylinders provided with a jack body secured to said anchoring support and a rod movable in translation in said body, and at least three ball joints, each ball joint being integral with the movable panel support and, on the other hand, on the one hand, of the rod of the cylinders, and in that said movable panel support is, on the one hand, displaceable in translation and, on the other hand, rotatable according to the respective position of the rods of said at least three jacks.

Advantageously, the anchoring support is mounted on or integrated with a frame; - the solar panels are photovoltaic panels; the device comprises at least one sensor able to measure values of parameters which are a function of sunlight; the sensor or sensors are radiation, current, voltage or temperature sensors; the device further comprises a card for acquiring the values of parameters measured by the sensors; - The device further comprises a control card of the position of the cylinders according to the acquired values of the parameters by the acquisition card, so that during the day, the panels follow the course of the sun; - the stroke of the cylinders is controlled independently; and the device further comprises rotary jacks.

The invention will be better understood on reading the nonlimiting description which follows, and with reference to the accompanying drawings, in which: - Figure 1, schematizes various means implemented according to the invention; FIG. 2A shows, in plan view, an anchoring support of a device according to the invention; - Figure 2B shows, in bottom view, a movable panel support of a device according to the invention; - Figure 3 shows, schematically, a device according to the invention oriented in a particular way thanks to the combined means 3e the invention; and - Figure 4 details said means for controlling the stroke of the cylinders of a device 20 according to the invention. The device according to the invention is a solar panel device. These solar panels include photovoltaic panels or thermal panels. It may, however, be any panels intended to capture the energy of the sun or return it to an oven as is the case in some of the aforementioned farms of the prior art. As is schematized in FIG. 1, the devices according to the invention comprise a fixed anchoring support 10 and a movable panel support 20. As is more particularly detailed in FIG. 2A, the support 10 comprises, in an exemplary embodiment, a rigid metal frame composed of four metal bars. First two bars 11, 12 are arranged parallel to each other in one direction. Two other bars 13, 14 are arranged parallel to each other, and perpendicular to the first two bars. The anchoring support 10 is assembled on a frame or integrated in such a frame, for example, an isolated dwelling, or it is fixed to the ground. It is held in place by fixing and / or anchoring lugs 15 and stop and lock stops having a return spring 16, in particular when the frame on which the support is attached has a slope. Preferably, one of the bars of the frame, for example the bar 14, is displaceable in translation along the bars 11, 12 which are perpendicular thereto, so as to adapt the device to the constraints imposed by the frame.

As is more particularly detailed in FIG. 2B, the support 20 comprises, in an exemplary embodiment, a rigid metal reinforcement composed of a frame 21 in which metal bars 22, 23 are arranged.

The support 20 carries one or more solar panels 30, 31. In the example of Figure 1, it carries two. These solar panels are assembled to said support 20, by means of conventional assemblies. Furthermore, the device according to the invention comprises at least three jacks 40, 41, 42. These jacks are for example hydraulic, pneumatic, mechanical or electrical. Each cylinder is provided with a cylinder body and a rod. The base or the head of each cylinder body is secured to the anchoring support 10, for example screwed into a threaded hole, the inclination of which is configurable, of the armature of said support 10. The rod of each cylinder is nun of a head. Said rod is movable in translation notches the cylinder body.

The axis of the cylinders, that is to say the axis in which the rod moves, is usually positioned vertically, and therefore perpendicular to the ground. The angle of inclination is adjustable relative to the plane defined by the support 10. In addition, the cylinders are not positioned aligned in the plane of said support. They are positioned to form a triangle, for example an isosceles triangle, as it appears in particular in Figure 2A.

According to a particular embodiment of the invention, the above cylinders are coupled to rotary cylinders. In this embodiment, the support becomes triaxial. In addition, the device according to the invention comprises at least three ball joints 50, 51, 52. Each ball joint is integral with a jack rod directly, or indirectly, when the ball is attached to the head of the rod. cylinder. Each ball is further secured to the movable support 20.

The ball joints 50, 51, 52 may be said to be active or passive. For example, so-called active ball joints would consist of rotary cylinders. Thus, the support 20 overhangs the support 10 which carries the panels 30, 31. In addition, said support 20 is adjustable according to the position of the cylinders, and thanks to the ball joints. This is shown diagrammatically in FIG. 3. In this figure, the support 20 is shown oriented in a given position offset from that of the anchoring support 10, this offset position being defined by the different stroke controlled independently of the three jacks 40. , 41 and 42. Of course, the supports 10 and 20 as well as the other components of the device according to the invention are designed to withstand the various external influences such as snow, gusts of wind and the salty environment. Finally, the device according to the invention comprises means for controlling the jacks. These means are formed by sensors 60, one or more cards 70 for data acquisition and control cylinders, and a computer / local server 80. More specifically, and as shown in Figure 5, the sensors 60 are connected to the cards 70 by any connection means 90. The cards 70 are themselves connected to the cylinders 40, 41, 42 by connection means 100 which allow to control these cylinders. Moreover, the cards 70 are connected to the computer / local server 80 by any connection means 110, for example USB-type cables and an Ethernet-type local area network. The sensors 60 measure parameter values depending on the climatic environment, ie, sunning. These sensors are, for example, sensors for radiation, current, voltage or temperature. Thus, when the panels are photovoltaic panels, the measured values constitute production data or electricity production environment, which can be collected according to the invention. For this purpose, the values measured by the sensors 60 are transmitted to the card 70. The measured values acquired by the card 70 are then transmitted via the means 110 to the local server 80, where they are stored.

The server 80 analyzes the received data, determines an optimum position of the panels according to the maximum energy gain constraint, then sends back to the card 80, more particularly to the part relating to the control of this card, instructions for piloting the jacks so that the optimum position is implemented.

These instructions are for example communicated by the Ethernet / USB 110 or powerline network. The card 70, which receives these instructions pilot three cylinders 40, 41 and 42 independently for the panels carried by the support 20 are in optimum position relative to the sun. The above operations are performed substantially in real time. As a result, the panels, which follow the course of the sun, is continuous. Note that, according to a particular embodiment of the invention, the device is capable of operating autonomously with monitoring and acquisition without server / local computer. According to this embodiment, the panel simply follows the course of the sun for example at the azimuth. In this case, the actuation of the cylinders is carried out for example by an internal digital card based on a microcontroller coupled with sensors (optoelectronic, coi.rant, voltage, temperature, ...). Energy production is maximized. It is estimated that this production is 40 times greater than the production of a system equipped with devices comprising the same number of panels, with the same surface, but which do not follow the course of the sun. Thanks to the invention, the energy gains, in particular the electrical energy produced, are therefore sensitive. It will be noted moreover that, thanks to the combined means according to the invention, the administration of the solar panel devices can be carried out remotely. It will furthermore be noted that the energy provided by the device according to the invention can be recovered for powering the cylinders and the cards of said device, which thus becomes autonomous with respect to its energy consumption.

Of course, the invention is not limited to the embodiments described above. It must be conceived within a broad framework, as encompassing all embodiments within the scope of the claims.
