Description

Modular unit for floating solar power plant and method of manufacture

The present invention relates to a modular unit for a floating solar power plant and a manufacturing method thereof.

Floating solar power plants are devices for generating electricity from solar panels, which are manufactured in the form of islands that can accommodate solar panels, and which can float on extended waters such as lakes or ponds. The islands may be composed of a plurality of modular units assembled with each other and arranged according to the desired form, with each modular unit containing one or more solar panels.

Modular units typically consist primarily of a floating mount, a solar panel, and an attachment system that holds the solar panel on the floating mount.

Currently, solar panels are roughly rectangular in shape, which includes two large edges and two small edges. At present, the attachment system is used to hold the two large edges of the solar panel.

By way of example, Korean Patent Application Publication No. 1020160083441 discloses a modular unit including a solar panel in a rectangular shape, a floating bracket for accommodating the solar panel, and means for attaching the solar panel to the floating bracket to provide The device is held on the two large edges of the solar panel.

Continuing from the above, as can be seen in FIG. 3 (not shown) of this document, the attachment device includes two fitting feet (marked with reference numeral 131 in the above-mentioned Korean patent application, not specifically referenced below), the fitting The mounting feet are substantially connected to the corners of the front edge of the floating bracket, and the two substantially parallel mounting tubes (marked with reference numeral 134 in the above-mentioned Korean Patent Publication, and will not be specially marked below), which are substantially connected to the The corner position of the rear edge of the floating bracket to ensure that the solar panel is attached to its two large edges, eg at two points on each large edge. Each fitting foot and each fitting tube are fitted at opposite ends of the floating bracket through holes to accommodate the pivot bolts. The solar panel is assembled on the fitting foot and the fitting tube by means of four attachment flanges (flange, which are marked with reference numerals 132 and 136 in the above-mentioned Korean Patent Publication, and are not particularly referenced below), and the four attachment flanges Attached at four points for the solar panel, the attachment flange also includes two holes to accommodate the pivot bolts.

Thus, each attachment flange is assembled: at the location of the first end of each fitting tube attached to the floating bracket, around the pivot bolt on each fitting foot and the The pivot bolt pivots. Furthermore, each fitting tube is slid in at its second end and is accommodated in an adjustment tube (marked with reference numeral 133a in the above-mentioned Korean Patent Publication, and is not particularly referenced below). The adjustment tube is assembled to be pivotable on a floating support, which is arranged parallel to the solar panel and perpendicular to the fitting tube. A peg (marked with reference numeral 135 in the above-mentioned Korean Patent Publication, not particularly referenced below) is used to move each fitting tube forward relative to the adjustment tube when the solar panel is positioned according to the desired inclination relative to the floating bracket move.

The attachment device described above has the advantage of creating an association between the solar panel and the floating bracket, which can adjust the panel according to different inclinations on the floating bracket (see FIG. label). To do this, slide the fitting tube into the adjustment tube until the desired inclination of the panel is achieved, then lock the position by inserting the pegs into the most suitable adjustment holes on the fitting tube.

However, such an attachment device has the disadvantage that the solar panel is connected to the floating support through the intermediary of pivot links with all parallel axes. Therefore, when the force is connected according to the pivot When the axis of the rod is oriented, that is, according to the axis of the adjustment tube, this attachment means cannot prevent the transmission of forces between the solar panel and the floating support.

For example, a floating stent will withstand the forces resulting from its deformation during expansion as the material of which it is constructed shrinks. Furthermore, such modular units are usually connected to other modular units in the floating bracket to form a floating station, or to the ground to hold the floating station in place, which will also generate forces in the floating bracket.

In addition, according to the inventor's observation, the fitting pipes of the attachment device of this document must be arranged parallel to each other to realize the aforementioned tilt adjustment, which will affect the stability of the solar panel on the floating support, so that the solar panel is relatively Because the floating support is in an unstable equilibrium position.

Indeed, and according to the observations of the inventors, the upper wall of the fitting tube with the floating support and the large edge of the solar panel define a rectangle which, in the case of holding the solar panel in the direction of the large edge, will make it easy to convert into Parallelogram (not rectangular), thus preventing the solar panel from returning to its original position relative to the floating support.

This solar panel tilt adjustment system involves sliding the fitting tube into the adjustment tube until the desired position, but it does not allow for a way of positioning the attachment tube relative to the floating bracket.

Therefore, in this Korean document, the attachment flanges on the solar panel are two points located in the middle area of the solar panel and closer to the median plane at both ends of the large edge of the panel (hereinafter referred to as the attachment point). Consequently, forces applied to the sides of the solar panel away from the point of attachment, especially those due to wind, create significant bending stresses in the panel due to the attachment of the solar panel to the point at which such forces are applied. There is a significant lever arm factor between the contacts, so in the long run, this will more or less cause damage to the solar panel.

Furthermore, through another document, Patent Publication No. WO2014/165609A1, a system for assembling solar panels is disclosed, which is a rubber ring for solar panels.

The support used in this document is to ensure that the solar panel is placed directly on the ground.

According to this document WO2014/165609A1, as shown in Figures 1 to 3 of this document (not shown here), the panel is provided with a frame, and the frame is used to cover the edge of the panel, especially the large edge of the solar panel, The panel is provided in a generally rectangular shape. A plurality of beams are used to form the above-mentioned frame at the location of the large edge, and these beams are connected to curved plates (marked with reference numerals 7 and 18 in the above-mentioned WO patent publication, not specifically referenced below) that slide along the beams. A curved plate (marked with reference numeral 7 in the above-mentioned WO patent publication, not particularly referenced below) located at the front edge of the solar panel is directly disposed on the upper surface of the rubber ring.

The rear bending plate (marked with the reference numeral 18 in the above-mentioned WO patent publication, not particularly marked below) is arranged at a distance away from the first pair of tubular objects (marked with the reference numeral 17 in the above-mentioned WO patent publication, hereinafter not particularly marked). rubber ring, thus ensuring the tilt of the panel.

On top of that, the first pair of tubes is positioned substantially on a vertical plane at the rear edge of the solar panel, and such that the upper end of each tube is positioned on the curved plate at the rear edge of the solar panel, and such that each tube is The lower end of the object is set on the rubber ring located at the rear edge of the rubber ring.

It is worth noting that the second pair of tubes (marked at 26 in the aforementioned WO patent publication) are arranged: on the one hand, by being attached to the lower end of each of the aforementioned tubes, near the upper surface of the rubber ring and substantially The horizontal plane, on the other hand, is connected to the front edge of the panel on the curved plate.

Therefore, after having the panels set on the rubber ring at the desired inclination, the operator can tighten all the attachments to ensure that the pair of tubes is mounted on the rubber ring and on the solar panel for the The unit adds rigidity and prevents movement of the solar panel relative to the rubber ring.

However, this device for mounting the panels on the rubber ring has the disadvantage that the solar panel is rigidly mounted on the rubber ring. In practice, a pair of tubes (marked at 26 in the aforementioned WO patent publication) are used, arranged substantially horizontally, to connect between the curved sheet at the rear edge of the solar panel and the rubber ring , and the attachment points of the curved panels that connect the rear edge of the solar panel on the rubber ring to prevent relative movement of these attachment points.

Thus, in particular, the rubber ring, made of flexible rubber, can be deformed to act as a buffer to withstand the forces received by the solar panel and the attachment means on the solar panel. In effect, the forces received by the solar panel are dispersed by the tube of the attachment device so that it remains in a set position and is transmitted to the rubber ring, which deforms to withstand these forces.

However, according to the inventors' observations, such attachment means are not really suitable for assembling solar panels on floating supports. In fact, floating mounts are usually hollow shells made of thermoplastic material, so they don't deform as easily to withstand impacts as the rubber on a tire. Therefore, the use of the attachment means on the thermoplastic shell, in particular the above-mentioned pair of horizontal tubes, confines the floating support in height, especially in the horizontal direction, which will cause more or less damage to the floating support in the long term.

Therefore, the present invention proposes to compensate for these drawbacks: the present invention proposes a modular unit for a floating solar power plant, which makes it possible to reduce the influence between the solar panel and the floating support housing the solar panel, especially when the floating support contracts or expands, At the same time, it is ensured that the solar panels are optimally held on the floating support regardless of the weather conditions, especially in the case of strong winds.

The present invention also proposes a modular unit (1), which can be manufactured simply, quickly and with low cost.

Therefore, the present invention relates to a modular unit for a floating solar power station, the modular unit comprising: a floating bracket (2) for supporting a solar panel; a rectangular solar panel (3) comprising two Two parallel four edges: a first large edge (B1), a second large edge (B2) and two small edges; An attachment system to ensure that the solar panel (3) is held on the floating support (2) at its two major edges (B1, B2), characterized in that the attachment system comprises: a first holding device (4), which is Make sure that the solar panel (3) remains on the floating support (2), at the height of at least one first attachment point (F4) on the floating support (2), place the first large edge (B1) of the solar panel (3) ) is connected to the floating support (2); and a second holding device (5), which ensures that the solar panel (3) is maintained at the height of the second largest edge (B2) of the solar panel (3), the second holding device (5) ) includes a first holding arm (51) and a second holding arm (52), each holding arm (51, 52) includes an upper end (E51s, E52s) and a lower end (E51i, E52i), the first holding The upper end (E51s) of the arm (51) is assembled at the height of a first attachment point (F1) of the solar panel (3) through the medium of a first upper joint (A51s) so that it is relative to the solar panel (F1). 3) Pivoting; the upper end (E52s) of the second holding arm (52) is assembled at the height of a second attachment point (F1') of the solar panel (3) into the medium through a second upper joint (A52s) , so that it pivots relative to the solar panel (3); the lower end (E51i) of the first holding arm (51) is assembled at the height of a first attachment point (F2) of the floating bracket (2) through a first the medium of the lower joint (A51i) to pivot relative to the floating bracket (2); and a second attachment point (F2) of the lower end (E52i) of the second retaining arm (52) on the floating bracket (2) ') is assembled through the medium of a second lower joint (A52i) allowing it to pivot relative to the floating support (2), where the first attachment point (F1) on the solar panel (3) is connected to the second the gap (E1) between the attachment points (F1') is strictly greater than the gap (E2) between the first attachment point (F2) and the second attachment point (F2') on the floating bracket (2); and the first attachment point (F2) and the second attachment point (F2') define a Bolting range (E24), when the floating bracket (2) is deformed, the first upper joint (A51s), the second upper joint (A52s), the first lower joint (A51i) and the The second lower joint (A52i) is configured so that the structure formed by the first holding arm (51) and the second holding arm (52) can maintain stress-free deformation when the bolting range (E24) changes.

It should be noted that the drawings are for illustrative purposes only, and do not represent the actual size or number of components, and some details may not be fully drawn for the sake of simplicity in the drawings.

The present invention relates to a modular unit 1 for a floating solar power station, comprising: a floating bracket 2 for supporting solar panels; a rectangular solar panel 3 comprising four edges parallel to each other: a first large edge B1, a second large edge B2 and two small edges; an attachment system to ensure that the solar panel 3 remains on the floating support 2 at its two major edges B1, B2, characterized in that the attachment The system comprises: a first holding device 4, which ensures that the solar panel 3 is held on the floating support 2, at the height of at least one first attachment point F4 on the floating support 2, the The first large edge B1 of the solar panel 3 is connected to the floating bracket 2; and a second holding device 5 is used to ensure the height of the second largest edge B2 of the solar panel 3 relative to the floating bracket 2, so The second holding device 5 includes a first holding arm 51 and a second holding arm 52, and each holding arm 51, 52 includes an upper end E51s, E52s and a lower end E51i, E52i. The upper end E51s is assembled at the level of a first attachment point F1 of the solar panel 3 to pivot relative to the solar panel 3 through the medium of a first upper joint A51s; the second The upper end E52s of the retaining arm 52 is assembled at the height of a second attachment point F1' of the solar panel 3 to pivot relative to the solar panel 3 through the medium of a second upper joint A52s; The lower end E51i of the first holding arm 51 is assembled at the height of a first attachment point F2 of the floating bracket 2 through the medium of a first lower joint A51i, relative to the floating bracket 2 pivot; and the height of a second attachment point F2' of the lower end E52i of the second holding arm 52 on the floating bracket 2 is assembled through the medium of a second lower joint A52i so that its Pivoting relative to the floating bracket 2 , wherein the gap E1 between the first attachment point F1 and the second attachment point F1 ′ on the solar panel 3 is strictly larger than that on the floating bracket 2 the gap E2 between the first attachment point F2 and the second attachment point F2 ′; and the first attachment point of the first holding arm 51 provided on the floating bracket 2 F2 and the second attachment point F2 ′ of the second holding arm 52 provided on the floating bracket 2 , and the at least one of the first holding means 4 provided on the floating bracket 2 A bolting range E24 is defined between an attachment point F4. When the floating bracket 2 is deformed, the first upper joint A51s, the second upper joint A52s, the first lower joint A51i and the The second lower joint A52 is configured so that the structure formed by the first holding arm 51 and the second holding arm 52 can maintain stress-free deformation when the bolting range E24 changes.

In one embodiment, the attachment points F1 , F1 ′ of the holding arms 51 , 52 on the solar panel 3 are arranged as symmetrically as possible with respect to the central plane PM (marked in FIG. 11 ) of the solar panel 3 , that is, the holding arms The attachment points F2, F2' of 51, 52 on the floating support 2 are arranged as symmetrically as possible with respect to the central plane PM of the solar panel 3 (marked in Fig. 11).

According to the invention, the gap E1 between the two attachment points F1, F1' on the solar panel 3 is strictly larger than the gap E2 between the two attachment points F2, F2' on the floating support 2.

Viewed from the back, as shown in FIG. 2 , the structure formed by the two retaining arms 51 , 52 outlines the two equilateral sides of the isosceles trapezoid.

According to the invention, the bolting range E24 on the floating bracket between the attachment points F2, F2' of the holding arms 51, 52 on the floating bracket 2 and the attachment point F4 of the first holding means 4 on the floating bracket 2, In particular, the bolting range E24 along the horizontal direction DH1 is configured to be freely changeable when the floating bracket 2 is deformed along the horizontal direction DH1.

Thus, in contrast to prior art devices, such as that defined in document WO 2014/165609 A1, the attachment points are not rigidly connected in particular by means of this prior art tube (marked 26 in the aforementioned document). Due to this advantageous configuration of the present invention, the number of parts required to manufacture such a modular unit is reduced, thus reducing the complexity of manufacture and its cost price.

According to the present invention, its first upper joint A51s, second upper joint A52s, first lower joint A51i and second lower joint A52i are configured to be formed by the two holding arms 51, 52 when the bolting range E24 changes The structure is able to maintain stress-free deformation.

Thus, the attachment system of the modular unit 1 according to the invention, in particular the four joints A51s, A52s, A51i, A52i, is in contrast to the devices of the prior art, for example as defined in the document WO2014/165609A1 The assembly between the second largest edge B2 of the solar panel 3 and the floating bracket 2 can be ensured, and is configured such that stress-free deformation of the structure formed by the two holding arms 51 , 52 enables the solar panel 3 and the floating bracket 2 to be realized A non-rigid connection between the two elements to avoid the transfer of forces during the mixed expansion between these two elements.

Due to the use of these four joints A51s, A52s, A51i, A52i, the specific force received by the floating support 2 is not transmitted to the solar panel 3 . Conversely, the specific forces received by the solar panel 3 are not transmitted to the floating support 2 either. For example, the force generated by the deformation of the floating bracket 2, especially the floating bracket 2 group forces generated during expansion or contraction of the resulting material, or by the locking of modular units 1 to other modular units 1 to facilitate holding the floating station in place on the ground, Build floating stations.

Through the rotation of the holding arms 51 , 52 relative to the floating bracket 2 and the rotation of the holding arms 51 , 52 relative to the solar panel 3 , the deformation of the floating bracket 2 can be fully absorbed and therefore not transmitted to the solar panel 3 .

In particular, as can be seen, for example, in the embodiments of FIGS. 3 and 6 of the present case, when the force that the floating support 2 is subjected to is a force oriented along the horizontal direction DH1, these will produce the material of the floating support 2 along the horizontal direction. Expansion or contraction in direction DH1. This deformation of the floating support 2 will not cause stress in the solar panel 3, since the holding means 4, 5 according to the invention are able to change the gap E24 between the attachment points F2, F2' and the attachment point F4. In response, this choice of modifying the gap E24 will only enable the forces borne by the solar panels 3 to be absorbed by this relative movement between said attachment points F2, F2' and F4 and will not be transmitted to the floating support 2 .

This rotation of the holding arms 51 , 52 relative to the floating bracket 2 and relative to the solar panel 3 will cause a slight change in the inclination of the solar panel 3 relative to the floating bracket 2 and the solar panel 3 will not be able to transmit the force to it by the floating bracket 2 . will not be damaged under the action.

Furthermore, the fact that the gap between the two attachment points F1 , F1 ′ is strictly larger than the gap between the attachment points F2 , F2 ′ advantageously allows the two retaining arms 51 , 52 to pass through the second contact with the solar panel 3 The large edge B2 and the upper wall 21 of the floating bracket 2 are defined to form an isosceles trapezoid, as shown in FIG. 2 .

On top of that, due to the isosceles trapezoid configuration of the holding arms 51, 52, the solar panel 3 can therefore remain particularly stable at its second large edge B2, even when applied in the direction of the first large edge B1, the second large edge B2 In this case, the holding arms 51 and 52 can also be held at their original positions with respect to the floating bracket 2 of the solar panel 3 . And in contrast to prior art devices (eg the device defined in document KR1020160083441).

According to an embodiment, the floating bracket 2 may be mainly made of a plastic casing, and defines an upper wall 21 , a lower wall 22 and four side walls 23 , 24 , 25 , 26 . As shown in FIGS. 1 to 3 , the attachment system may be positioned on the upper wall 21 of the floating bracket 2 . To this end, the upper wall 21 may be substantially parallel to the lower wall 22 .

The floating bracket 2 may be generally rectangular in shape, and may include attachment means, such as lugs (as shown in Figure 18), which are held tightly together with the plastic housing. These lugs are for example provided at the four corners of the floating supports 2 in order to be able to be assembled with other floating supports 2 to manufacture the solar power plant.

In one embodiment, the floating bracket 2 is a plastic casing. Thus, the floating bracket 2 can be made, for example, from a thermoplastic material through an extrusion blow moulding process.

On top of that, such a floating bracket 2 made of thermoplastic material by extrusion blow moulding process can be seen in the embodiment in FIG. 18 .

In fact, extrusion blow moulding is a method of manufacture that is particularly suitable for the manufacture of hollow parts made of thermoplastic materials, especially the thickness of the shell of the hollow parts is less than 10 mm, for example about 3 mm, since this thickness is generally more suitable for the kind of floating bracket 2.

As shown in FIGS. 1 to 3 , the first holding means 4 can hold the first large edge B1 of the solar panel 3 near the upper wall 21 of the floating bracket 2 , and the second holding means 5 can be configured to hold the solar panel 3 The second large edge B2 remains away from the upper wall 21 of the floating bracket 2 .

Therefore, when the modular unit 1 is arranged on water, the solar panel 3 can be found to be tilted horizontally.

9 or 14 to 16 , the holding arms 51 , 52 of the second holding device 5 can be manufactured, for example, in the form of metal or plastic as a tube or arm with a square cross-section. In order to efficiently simplify the manufacture of the attachment system of the modular unit 1, the retaining arm 51 and the retaining arm 52 may be identical.

In addition, the lengths L51, L52 of the holding arm 51, the holding arm 52 determine the gap between the second largest edge B2 and the upper wall 21 of the floating bracket 2, and thus determine the horizontal inclination of the solar panel 3. The angle of this inclination can be between 5 degrees and 40 degrees.

In particular, if it is desired to change the inclination angle of the solar panel 3 horizontally, it is only necessary to replace the holding arms 51, 52 of the original lengths L51, L52 with the holding arms 51, 52 of different lengths L51, L52, or Provide a telescopic holding arm 51 and a holding arm 52 with a certain length L51 and L52 that can be manually adjusted.

If you want to change the inclination angle of the solar panel 3 regularly, for example, in order to be able to instantly and dynamically adapt it to the position that best receives solar energy, you can consider making the holding arms 51 and 52 telescopic arms, for example by The actuator system can electrically control its extended length.

According to an embodiment, the first lower joint A51i (as shown in FIG. 13 ) and/or the second lower joint A52i are (as shown in FIG. 13 ) the pivot links P51i and P52i of the axes AP51i and AP52i. When on the water, the axes AP51i, AP52i are perpendicular to the horizontal direction DH1 and are substantially vertical.

Thus, as can be seen for example in Figures 14 and 15, each holding arm, eg the first holding arm 51, the second holding arm 52, can be at the attachment point F2 or the attachment point F2' to surround the axis AP51i or to The rotation is performed in the manner of the axis AP52i to withstand the forces at the attachment points F2, F2" and directed along the horizontal direction DH1, for example represented by the arrow FP. The structure formed by the holding arms 51, 52 allows this pivoting in the gap During the change of E24, stress-free deformation was maintained.

This effective configuration of the present invention enables the forces received by the solar panel 3, such as the forces oriented in the horizontal direction DH1, to be absorbed by the holding arms 51, 52 by pivoting relative to the floating bracket 2, through the holding arms 51, 52 Not transmitted to the floating support 2, on the contrary, in the same way, the force received by the floating support 2, such as the force oriented along the horizontal direction DH1, is not transmitted to the solar panel 3 either.

According to one embodiment, at least one pivot link P51i, P52i is formed by the connection of an attachment housing 56i with a pivot bolt 57i, the axis of the attachment housing 56i defining the axis AP51i, P52i of the pivot link P51i, P52i, AP52i, a pivot bolt 57i is housed in the attachment housing 56i to pivot about the axes AP51i, AP52i of the pivot links P51i, P52i.

On top of that, the attachment housing 56i can advantageously be partly in the holding arm 51 , the holding arm 52 or partly in the floating bracket 2 . In this case, the attachment housing 56i may comprise a first part P56i and a second part P56i', wherein the first part P56i is manufactured in the form of a hole arranged at the lower end E51i, E52i of the holding arm 51, the holding arm 52, and the second part P56i' is arranged in the floating bracket 2 and manufactured in the form of a hole.

Alternatively, the first part P56i of the attachment housing 56i may be provided on a part additional to the holding arm 51, the holding arm 52, and this part is attached between the holding arm 51, the lower ends E51i, E52i of the holding arm 52 In other words, the first part P56i can be located on another part which does not belong to the holding arms 51,52 but is connected to the holding arms 51,52.

Advantageously, the pivot bolt 57i is manufactured in the form of a cylindrical part housed in the attachment housing 56i in order to pivot the pivot bolt 57i through the medium of a bearing.

In order to facilitate the assembly of the pivot bolt 57i on the floating bracket 2, in one embodiment, the pivot bolt 57i may be in the form of a detachable pin, or may be manufactured in the form of a screw-in element.

According to one embodiment, the first upper joint A51s and/or the second upper joint A52s are manufactured in the form of ball joint links R.

Thanks to this advantageous configuration of the invention, the solar panel 3 can be pivoted relative to each of the holding arms 51, 52 at the attachment points F1, F1' to ensure an elastic connection between the solar panel 3 and the floating bracket 2 ( flexible connection) to withstand the force of the solar panel 3 or the floating support 2.

In particular, as can be seen in the embodiments of FIGS. 14 and 15 , the rotation of the solar panel 3 relative to the holding arms 51 , 52 can take place around three axes of rotation A1 , A2 , A3 , in particular parallel to the The pivoting link P51i, P52i axis AP51i, rotation axis A3 of AP52i is carried out.

According to another embodiment shown in FIGS. 1 to 12 , the first upper joint A51s, the second upper joint A52s, the first lower joint A51i and the second lower joint A52i may be manufactured in the form of ball joint links R.

Due to this advantageous structural configuration of the invention, the solar panel 3 rotates relative to each holding arm 51 , 52 at the attachment points F1 , F1 ′ about the three axes of rotation A1 , A2 , A3 and the floating bracket 2 also rotates relative to Each holding arm 51, 52 rotates about three rotation axes A1', A2', A3' at attachment points F2, F2'.

Therefore, regardless of the orientation of the solar panel 3, the force borne by the solar panel 3 can be fully recovered through the deformation of the structure formed by the holding arms 51, 52, and is not transmitted to the floating bracket 2, and conversely, due to the The deformation of the structure formed by the holding arms 51 , 52 will not transmit the force received by the floating bracket 2 to the solar panel 3 regardless of its direction.

In one embodiment, each ball joint link R is formed by connecting an attachment ring 53i, 53s with pivot bolts 54i, 54s, the axes A53i, A53s of the attachment rings 53i, 53s defining the first axis of the ball joint link R. A rotation axis A1, A1', pivot bolts 54i, 54s are accommodated in the attachment rings 53i, 53s to surround the first rotation axis A1, A1', the second rotation axis A2, A2' and the third rotation axis A3 , A3' pivot, wherein the second rotation axis A2, A2' is perpendicular to the first rotation axis A1, A1', and the third rotation axis A3, A3' is perpendicular to the first rotation axis A1, A1' and perpendicular to the second Rotation axis A2, A2'. The angular amplitude α1, α1' of the rotation about the first axis of rotation A1, A1' is strictly greater than the angular amplitude α2, α2' of the rotation about the second axis of rotation A2, A2' and greater than the rotation about the third axis of rotation A3, A3' The angular amplitude α3, α3'.

This ball joint link R is a simple and feasible embodiment. According to the inventor's observation, although it is not necessary to use the ball joint link R, if it must be based on the three rotation axes A1, A1', A2, A2 ', A3, A3' are rotated to provide the same angular amplitude, which would require the use of more complex spherical surfaces that can cooperate with each other, which would increase the cost.

Advantageously, as shown in Figures 5 and 6, the first axis of rotation A1, which corresponds to the axis A53s of the attachment ring 53s, is perpendicular to the first large edge B1, the second, when it is attached to the solar panel 3, The large edge B2 is oriented and in one embodiment as parallel as possible to the small edge of the solar panel 3 . An axis of rotation A1', corresponding to the axis A53i of the attachment ring 53i, is oriented perpendicular to the first large edge B1, the second large edge B2 when connected to the floating bracket 2, and in one embodiment as far as possible Parallel to the lower wall 22 of the floating bracket 2 .

In fact, according to the inventor's observations and adapted to the problem of deformation of the floating bracket 2, during the expansion or contraction of the material of the floating bracket 2, the angle by which the ball joint link R rotates about the axis of rotation A2, A2' and A3, A3' The amplitude does not need to be as large as the angular amplitude of the rotation around the axis of rotation A1 , A1 ′ to be able to ensure that the holding arm 51 , the holding arm 52 rotate relative to the solar panel 3 and the floating bracket 2 so that due to the deformation of the floating bracket 2 there is no A force is generated in the solar panel 3 .

During assembly, and more importantly, the rotational amplitude around the axis of rotation A1 , A1 ′ is useful, which can be achieved by: at the attachment points F1 , F1 ′ of the solar panel 3 , by making pre-assembled on the solar panel 3 The upper holding arm 51 and the rotation axis A1 of the ball joint link R that the holding arm 52 surrounds are folded downward toward the solar panel 3 to limit the volume of the first pre-assembled unit 11 during subsequent storage and/or transportation .

This method is defined in detail below.

The rotation of the pivot bolts 54i, 54s relative to the attachment rings 53i, 53s about the axes of rotation A2, A2' and A3, A3' can be achieved through the specific shape of the attachment rings 53i, 53s and/or through the pivot bolts 54i, 54s An interlocking space between the attachment rings 53i, 53s is achieved.

The particular shape of the attachment rings 53i, 53s and/or the dimensions of the interlocking spaces between the attachment rings 53i, 53s via the pivot bolts 54i, 54s will in particular be determined around the axes of rotation A2, A2' and A3 , the angular amplitudes α2, α2', α3, α3' of the rotation of A3'.

According to an embodiment, the angular amplitudes around the second axis of rotation A2, A2' and around the third axis of rotation A3, A3' are between 5 and 30 degrees.

In a preferred embodiment, the angular amplitude around the first rotation axis A1, A1' may be between 30 degrees and 60 degrees.

According to an embodiment, the at least one attachment ring 53i, 53s is annular. The annular shape of the ring effectively rotates the pivot bolts 54i, 54s about the three axes of rotation A1, A1', A2, A2', A3, A3'.

Alternatively, other shapes can be considered for the attachment rings 53i, 53s, such as a ring with a triangular or diamond-shaped cross-section, so that the pivot bolts 54i, 54s can be around the three axes of rotation A1, A1', A2, A2', A3, A3' rotation.

According to an embodiment, the attachment rings 53i of the ball joint links R at the attachment points F2, F2' on the floating bracket 2 are arranged on the floating bracket 2 such that their respective centers C53i pass parallel to the solar panels The lines Di of the first large edge B1 and the second large edge B2 of 3 are connected.

As can be seen in Figure 9, once inserted into the respective holes 55s, 55i (as shown in Figure 6), the hole 55i for receiving the pivot bolt 54i is parallel to the hole provided for receiving the pivot bolt 54s 55s, so that the pivot bolt 54i and the pivot bolt 54s are arranged in parallel.

As can be seen in Figure 4, each retaining arm 51, 52 can be dimensioned to accommodate at least one attachment ring, advantageously two attachment rings 53i, 53s, inside it.

As shown in Figure 6, the axis A54i of the pivot bolt 54i is combined with the axis A53i of the attachment ring 53i, in particular the pivot bolt 54i, which is arranged to cooperate with the attachment ring 53i opposite and attached to the floating bracket 2 .

Alternatively, as can be seen in the embodiments of Figures 13 to 17, the attachment rings 53i, 53s may be configured in a portion of the attachment portion P53s comprising a plurality of flat surfaces, including a flat support surface FP53s and a flat attachment The surface FA53s, the flat supporting surface FP53s are provided to be supported flatly on the flat surface of the solar panel 3 or the flat surface supporting the floating bracket 2, and the flat attachment surface FA53s is inclined with respect to the flat supporting surface FP53s, wherein the attachment rings 53i, 53s are configured in it.

Said flat support surface FP53s can be effectively attached to the side rails 32, 33 of the frame 31 surrounding the solar panel 3, for example by means of fastening screws or again by welding on said side rails 32, 33. Without departing from the scope of the present invention, it may also provide for the at least one attachment ring 53i, 53s, 54i, 54s to be rigidly attached at the ends E51i, E51s, E52i, E52s of the retaining arms 51, 52 by . The holes 55i, 55s provided in the solar panel 3 accommodate the corresponding pivot bolts 54i, 54s, and the pivot bolts 54i, 54s also cooperate with the attachment rings 53i, 53s.

The use of pins can facilitate and speed up the assembly and/or disassembly operations of the pivot bolts 54i, 54s in the associated attachment rings 53i, 53s.

To ensure that the pivot bolts 54i, 54s remain in position in the associated attachment rings 53i, 53s, retaining elements (not shown) may be provided on said pins forming the pivot bolts 54i, 54s. Processing rings (not shown) may also be provided on the pins.

Alternatively, any other element of the overall cylindrical shape may be provided to manufacture the pivot bolts 54i, 54s, such as bolts.

According to an embodiment, the first holding means 4 of the attachment system comprise a flexible profile 41 attached to the floating support 2 in a substantially longitudinal direction along the parallel large edges B1, B2 of the solar panel 3, The flexible profile 41 is configured such that it is possible to pivot the solar panel 3 relative to the floating support 2 about an axis AT oriented in a substantially transverse direction only by deformation.

Such a configuration can facilitate the assembly of the solar panel 3 on the floating support 2, since once the first large edge B1 of the solar panel 3 is attached to the floating support 2 via the flexible profile 41 of the first holding means 4, the solar The panel 3 can again be inclined relative to the upper wall 21 of the floating bracket 2 in order to adjust the inclination and/or to facilitate the attachment of the second large edge B2 of the solar panel 3 to the second holding means 5 .

As can be seen in Figures 2, 3, 5, 8, 10 and 11, the flexible profile 41 may be made of metal or plastic. This flexible profile 41 may advantageously be an L-shaped section that defines a horizontal arm 42 and a vertical arm 43 .

A number of holes may be regularly distributed on the two arms 42, 43 of the flexible profile 41 in order to ensure that the flexible profile 41 is attached to the floating bracket 2 and the solar panel 3 by means of attachment means (not shown) media such as screws superior. Any other attachment means may be provided in order to ensure the attachment of the flexible profile on the floating support 2 and/or on the solar panel 3, such as attachment clips or clamps.

The flexible profile 41 in this form of embodiment thus imparts a certain flexibility to it, which will therefore provide this flexible profile 41 with a hinge-like function, so that the solar panel 3 surrounds a parallel to the solar panel 3 with respect to the floating support 2 The axis AT of the large edge B1 is pivoted. For this purpose, a hinge can be provided on the flexible profile 41 , in particular at the connection between the two arms 42 , 43 .

Alternatively, and without departing from the scope of the present invention, the first holding means 4 of the attachment system may comprise any type of element capable of ensuring the forward fixation of the solar panel 3 relative to the floating support 2 while allowing the solar The panel 3 rotates relative to the floating support 2 about an axis of rotation parallel to the first large edge B1 of the solar panel 3 .

Thus, the first holding means 4 may, for example, comprise a groove, eg of triangular cross-section, arranged directly on the floating support 2 and dimensioned to accommodate the ribs of the first large edge B1 of the solar panel 3, said ribs and all The interlocking space between the grooves is set so that the solar panel 3 can pivot relative to the floating bracket 2 .

According to an embodiment, the solar panel 3 is equipped with a frame 31 comprising at least two side rails 32, 33 arranged to cover the large edges B1, B2 of the solar panel 3, the first part of the attachment system A holding device 4 and a second holding device 5 hold the solar panel 3 on the frame 31 .

The frame 31 can add rigidity to the solar panel 3 by preventing the solar panel 3 from being bent due to its own weight, especially when connected to the floating support 2 by means of an attachment system.

This frame 31 avoids damage to the solar panel 3 by accommodating the holding means 4 , 5 of the attachment system to accommodate said holding means 4 , 5 .

As can be seen in FIGS. 1 , 2 and 7 , the frame 31 may comprise two side rails 32 , 33 and possibly two cross bars 34 arranged to cover the small edges of the solar panel 3 .

In a preferred embodiment, the frame 31 is made of metal or rigid plastic, and each rail 34 or side rails 32 , 33 is made of a profile sized to accommodate the edge of the solar panel 3 . Holes may be provided on the side rails 32 , 33 to accommodate elements to which the first holding means 4 and/or the second holding means 5 can be attached. For example, two holes at the attachment points F1, F1' on the side rails 32 of the frame 31 can be provided in order to accommodate the attachment rings 53s of the second holding means 5 and ensure their attachment.

Alternatively, and as can be seen in FIG. 12 , at least one clamping profile 35 made of thermoplastic or metallic material and having a substantially C-shaped cross-section may be provided to accommodate the side rails 32 , 33 and the second retaining means 5 Attach the ring 53i or the flexible profile 41 of the first holding device 4 and ensure their attachment. The attachment of the side rails 32, 33 of the frame 31 in the clamping profile 35 can be by the clamping force exerted by the clamping profile 35 due to its C-shape and/or, by the clamping profile 35 and the side rails The clamping between 32, 33 is ensured, possibly by inserting a non-slip polymer material between the clamping profile 35 and the side rails 32, 33, and/or by adding or produce.

According to an embodiment, the solar panels 3 are arranged laterally and extend beyond both sides of the floating support 2 .

As can be seen, for example, in Figures 1, 2 and 11, this advantageous configuration of the invention enables to reduce the amount of material required to manufacture the floating bracket 2, since there is no need to provide a floating bracket 2 in which the The width L22 (ie the length of the side walls 22 and 23 ) is substantially equal to the width LB1 of the solar panel 3 (ie the length of the first large edge B1 or the length of the second large edge B2 ).

According to an embodiment, the attachment points F1, F1' of the first holding arm 51 and the second holding arm 52 on the solar panel 3 are located in attachment zones ZF1, ZF1', such as distances DPM, DPM', respectively, wherein from The respective distances DPM, DPM' of the central plane PM to the attachment points F1, F1' are strictly greater than the respective distances EB1, EB1' of said attachment point F1, F1' and its closest second largest edge B2, respectively Distance DEB1, DEB1'.

According to this advantageous configuration of the invention, as shown in FIG. 11 , in particular those forces due to the wind are exerted on the small edge of the solar panel 3 close to the attachment points F1 , F1 ′ of the second holding means 5 , thereby reducing the stress generated between the point where this force is applied and the attachment points F1, F1' of the solar panel 3, thus in contrast to the devices of the prior art, in particular the ones defined in document KR1020160083441, It more or less prevents damage to the panel in the long run.

The invention also relates to a method for manufacturing a modular unit 1 according to the invention, comprising the steps of: a) providing a solar panel 3 of rectangular shape, comprising four edges parallel to each other: two large edges B1 , B2 and two small edges; b) provide a floating bracket 2 for the solar panel; c) provide an attachment system for attaching the solar panel 3 to the floating bracket 2 for the solar panel, this attachment The system comprises a first holding means 4 and a second holding means 5; d) attaching the first holding means 4 of the attachment system on the floating support 2; e) attaching the solar panel 3 at its first large edge B1 on the first holding means 4 of the attachment system; f) attaching the upper end E51s, E52s of each holding arm 51, 52 of the second holding means 5 of the attachment system to the solar panel 3; and g) attaching the The lower end E51i, E52i of each holding arm 51, 52 of the second holding device 5 of the connection system is attached to the floating bracket 2.

This method is simple and quick to implement, as it does not require complex adjustments to the positioning of the solar panel 3 to ensure that it is attached to the floating support 2 in the desired position. Therefore, the operator only The different elements of the modular unit 1 need to be assembled to obtain the desired position of the solar panel 3 to be attached to the floating support 2 .

In fact, the position and inclination of the solar panel 3 relative to the floating support 2 is determined by the position of the attachment points F1 , F1 ′, F2 , F2 ′ of the second holding means 5 , the lengths L51 , L52 of the holding arms 51 , 52 , and The position of the first holding device 4 on the floating support 2 is predetermined.

Furthermore, each of steps d) to g) may be performed at least partially near the installation site of the modular unit 1 or at least partially remote from the installation site (eg at a factory).

According to an embodiment, the upper end E51s, E52s of each holding arm 51, 52 of the second holding device 5 comprises a hole 55s that accommodates the pivot bolt 54s of the rotation axis A1, which is also accommodated in the attachment ring 53s In, attached to the solar panel 3 at the attachment points F1, F1' and/or the lower end E51i, E52i of each holding arm 51, 52 of the second holding means 5 comprises a pivot that accommodates the axis of rotation A1' The holes 55i of the bolts 54i, which are also housed in the attachment ring 53i, are attached to the floating bracket 2 at the attachment points (F2, F2').

Step f) of the method according to this embodiment comprises the following sub-steps: f1) attaching the two attachment rings 53s on the attachment points F1, F1' on the solar panel 3; f2) attaching each retaining arm 51, F1' The holes 55s of the upper ends E51s, E52s of 52 mate with the corresponding attachment rings 53s; f3) implement each pivot bolt 54s in each hole 55s and in each corresponding attachment ring 53s, and/or step g) It includes the following sub-steps: g1) attaching the two attachment rings 53s on the attachment points F2, F2' on the floating bracket 2; g2) mate the hole 55i of the lower end E51i, E52i of each retaining arm 51, 52 with the corresponding attachment ring 53i; and g3) implement each pivot in each hole 55i and in each corresponding attachment ring 53i Axle bolt 54i.

Step g) applies when the four joints A51i, A51s, A52i, A52s of the second holding device are ball joint links R, as can be seen for example in the embodiments in FIGS. 1 to 7 , 11 and 12 .

In the case where the first lower joint A51i and the second lower joint A52i are pivot bolts P51i, P52i, each pivot link P51i, P52i is formed by connecting an attachment housing 56i with a pivot bolt 57i, the attachment housing 56i Comprising a first part P56i arranged on the holding arms 51, 52 and a second part P56i' arranged on the floating bracket 2, the axis of the attachment housing 56i defines the axis of the pivot links AP51i, AP52i, the pivot bolt 57i is accommodated In the attachment housing 56i for pivoting about the axis of the pivoting links AP51i, AP52i, as shown in the embodiment of Figures 13 to 18, step g) comprises the following sub-steps: g1') attaching each retaining arm 51, AP52i, The lower end E51i of 52, the first part P56i of the attachment housing 56i of E52i is matched with the second part P56i' of the attachment housing 56i arranged on the floating bracket; g2') each pivot is implemented in each attachment housing 56i Bolt 57i.

This configuration of the method according to the invention effectively enables the retaining arms 51 , 52 of the second retaining means 5 to be in the Reliable and fast attachment on the solar panel 3 and/or on the floating support 2 .

According to an embodiment, step f) and step g1 ) are performed before steps g2) and g3) in order to manufacture a first pre-assembled unit 11 comprising solar panels 3 equipped with attachment points at the attachment points The attachment rings 53s at F1, F1' and the holding arms 51, 52 of the second holding means 5 attached to the solar panel 3 through the medium of the pivot bolts 54s; and the second pre-assembled unit 12, the second The pre-assembly unit 12 comprises a floating bracket 2 fitted with attachment rings 54i attached at the attachment points F2, F2'; and steps g2) and g3) are performed to assemble the two pre-assembly units 11, 12 to manufacture the modular unit 1 . In one embodiment, step f) and step g1) are performed at the first workstation before steps g2) and g3), for example at the relay site or special in the custom assembly area or at the installation site of the modular unit. In yet another embodiment, the installation site of the modular unit is performed at the second workstation.

In a similar manner, in the case where the first lower joint A51i and the second lower joint A52i are pivot links P51i, P52i, steps g1') and g2') can be preceded in order to manufacture the first pre-assembly Unit 11, this first pre-assembled unit 11 comprises a solar panel 3 equipped with an attachment ring 53s attached at the attachment points F1, F1' and through with pivot bolts 54s for the medium to attach the arms 51, 52 of the second holding device 5 to the solar panel 3; and the second pre-assembled unit comprising the floating support 2, which may comprise a second attachment part P56i' of the attachment housing 56i, performing the steps g1 ′) and g2 ′) in order to assemble the two pre-assembled units 11 , 12 to manufacture the modular unit 1 . In one embodiment, step f) is performed at the first workstation, eg at the relay site or a specific assembly area or at the installation site of the modular unit. In yet another embodiment, the installation site of the modular unit in steps g1') and g2') is performed at the second workstation.

The installation location of the modular unit 1 refers to the location at or near the location of the solar power plant comprising said modular unit 1 during its operation, ie, during its implementation, for generating solar power.

Thus, the installation site of the modular unit 1 may for example consist of the edge of a section of water on which the floating solar power plant is provided for installation.

Due to this advantageous configuration of the method according to the invention, the modular unit 1 according to the invention can be produced particularly simply and quickly at the installation site, since only steps g2) and g3) of the method need to be carried out at the installation site, Alternatively, steps g1 ′), g2 ′) may be performed to manufacture the modular unit 1 .

For the same advantages, it can also be considered to perform step d) of the method at a relay site or a specific assembly area away from the installation site of the modular unit, and to perform step e) on the installation site of the modular unit.

Thus, as can be seen in particular in FIG. 8 , the second pre-assembly unit 12 may comprise a floating bracket 2 , in particular a flexible profile 41 , to which the first holding means 4 are attached.

For optimization, the attachment of the attachment ring 53i at the attachment points F2, F2' on the floating bracket 2 can also be performed at a relay site remote from the installation site or in a specific assembly area It therefore also belongs to the second pre-assembly unit 12 .
