Description

DESCRIPTION
A support for photovoltaic panel
Technical field
The object of the present invention is a support for a photovoltaic panel.
Solutions are known comprising a wedge-shaped concrete support for a photovoltaic panel.
Prior art
This support comprises a bushing that protrudes from an upper surface of the support inside the support itself. A fixing screw for fixing a bracket can be inserted into this bushing that enables the photovoltaic panel to be constrained on the support. This bushing comprises a cylindrical body. One end of the bushing is accessible from the outside of the support to insert the fixing screw. The other end is buried in the support and comprises an anti-extraction wing.
One drawback of this solution is linked to the fact that the support is made in a mould inside which the bushing is located and then filled with the concrete so that the bushing is buried in the concrete. Inside the mould, the bushing is retained by a connector screwed inside the bushing. In order to permit the extraction of the support from the mould, the screw first has to be loosened from the bushing. As the concrete has not yet completely cured, the set rototranslational movement can cause a movement and unbalancing of the bushing relative to the desired position.
Aim of the invention
In this context, the technical task underlying the present invention is to provide a support for a photovoltaic panel which obviates the drawbacks in the prior art as described above.
Further, an aim of the present invention is to provide a support for a photovoltaic panel that allows the precision of realisation to be optimised.
The defined technical task and the specified aims are substantially achieved by a support for a photovoltaic panel comprising the technical characteristics set forth in one or more of the appended claims. Brief description of the drawings
Further characteristics and advantages of the present invention will become more apparent from the approximate and thus non-limiting description of a preferred, but not exclusive, embodiment of a support for a photovoltaic panel, as illustrated in the accompanying drawings, in which:
- figure 1 shows a lateral view of a support according to the present invention;
- figure 2 shows a plan view of a support according to the present invention;
- figures 3 to 5 show three views of a component of a support according to the present invention;
- figure 6 shows a further component of a support according to the present invention.
Detailed description of preferred embodiments of the invention
A support for a photovoltaic panel is denoted in the appended figures by reference number 1. The support 1 comprises a body 2 made at least partially of concrete. The support 1 could possibly comprise a metal reinforcement. This reinforcement could be a metal frame clad in the concrete.
The body 2 in turn comprises a lower resting base 21. The lower base 21 rests on a shelf outside the support 1 . This body 2 suitably defines ballast for the photovoltaic panel. Suitably, the body 2 has a mass comprised between 10 and 150 kg.
The body 2 comprises a first wall 22 for connecting to the photovoltaic panel. The photovoltaic panel overlaps at least partially the first wall 22. Suitably the first wall 22 faces upwards. In particular, the photovoltaic panel covers at least one part of the first wall 22. The body 2 is suitably a body that is devoid of empty inner cavities.
The body 2 can for example comprise a connecting wall 23 that joins the first wall 22 and the lower base 21. The connecting wall 23 extends between the top and the bottom. The body 2 could be wedge-shaped. Possibly, this wedge could be truncated at at least one end. The body 2 could however also be shaped differently. For example, it could be flat or U-shaped (for example with two arms of the U at different heights; also in this case, the first wall 22 could be a wall facing upwards that is at an end of one of the two arms). For example, an angle comprised between the lower base 21 and the first wall 22 is comprised between 5° and 25°, preferably between 8° and 20°. For example, it could be shaped as a triangular prism (in which case the triangular face is lateral and extends between the top and the bottom, for example vertically). Suitably, the body 2 extends in thickness. For example, it has a thickness comprised between 3 and 15 centimetres. Suitably, the body 2 extends in thickness orthogonally to the triangular face of the wedge.
The support 1 comprises connecting means 3 connecting the photovoltaic panel (and/or an auxiliary element, for example a conduit or a stiffening bar that connects the various supports together) to the body 2.
The connecting means 3 comprises a bushing 31. The bushing 31 (advantageously starting from the first wall 22), protrudes inside the body 2. The bushing 31 is typically made of metal material. Suitably, the bushing 31 extends from the first wall 22 to the lower base 21. The bushing 31 is a female bushing.
The bushing 31 comprises a hollow element 311 and anti-extraction anchoring means 312 that protrudes away from the hollow element 311. The hollow element 311 has advantageously but not necessarily a cylindrical outer surface
The support 1 comprises constraining 33 means for constraining the photovoltaic panel and/or an auxiliary element to the bushing 31. The constraining means 33 extends partially into the hollow element 311 .
The anti-extraction anchoring means 312 protrudes away from the hollow element 311 at least along a first and a second orientation.
In particular, the anti-extraction anchoring means 312 comprises at least a first and a second wing 313, 314. The first wing 313 extends away from the hollow element 311 along the first orientation. The second wing 314 extends away from the hollow element 311 along the second orientation.
The first and the second wing 313, 314, in one embodiment that is not illustrated, protrude away from the hollow element 311 according to two distinct directions.
The first and the second wing 313, 314 in one alternative solution, protrude away from the hollow element 311 along the same direction but in two opposite directions.
The hollow element 311 and the first and the second wing 313, 314 combined thus define an upturned T.
Advantageously, the anchoring means 312 does not comprise other wings in addition to the first and the second specified above. Suitably, the bushing 31 can also comprise a third and/or a fourth wing. This solution can however require greater costs than the solution with two wings that thus constitutes a valid compromise. Possibly, the anti-extraction anchoring means 312 could define an annular element that surrounds the bushing 31. Also in this case, the anchoring means 312 extends away from the hollow element 311 at least along a first orientation and a second orientation (for example following respectively a first and a second radius exiting from the hollow body 311 ). In reality, the solution with the first and the second wing 313, 314 is preferable with respect to the solution in which the anchoring means 312 defines an annular element. In fact, the first and the second wing 313, 314 buried in the concrete, even if the concrete is not completely cured, provide greater resistance to a rotational movement (i.e. the movement that during the demoulding step is performed by the connector that supports the bushing before the concrete is introduced into the mould).
The anti-extraction anchoring means 312 and said hollow element 311 define a single monobloc. They thus define a single monobloc body.
The hollow element 311 is threaded internally for connection to said constraining means 33.
In the preferred solution, the constraining means 33 comprises:
-a threaded connector 331 that is inserted at least partially into said hollow element 311 ;
-a bracket 332 traversed by said threaded connector 331 and comprising at least one retaining arm 333 for retaining said photovoltaic panel. The bracket 332 can possibly comprise two retaining arms 333 for retaining two adjacent panels. Suitably, the bracket 332 comprises a hole traversed by the threaded connector 331. This threaded connector can comprise one at least partially threaded stem and an end head (replaceable by a nut). For example the threaded connector comprises an 8Mx50 screw with a cylindrical head and hexagonal key.
Suitably, the photovoltaic panel is connected to the body 2 in two zones; in a first zone this occurs via the connecting means 3 disclosed previously; in a second zone this can occur via additional connecting means 30 (that suitably has one or more of the features disclosed previously for the means 3).
Suitably, if the connecting means 3 is used to connect an auxiliary element (for example a stiffening bar, a conduit, etc.) it is advantageously connected to the body 2 at the connecting wall 23.
The object of the present invention is a photovoltaic system comprising: -at least one support 1 having one or more of the characteristics described above;
-a photovoltaic panel 4 connected to said support 1 .
This photovoltaic panel 4 interacts with the support 1 as illustrated previously.
Suitably, the photovoltaic panel 4 is supported by the support 1 and by an additional support 9. This additional support 9 is structurally identical to the support 1. Advantageously, the support 1 and the additional support 9 support two ends of the photovoltaic panel 4.
The object of the present invention is also a method for making a support 1 having one or more of the characteristics described hereinabove. The method comprises the following steps:
-making said bushing 31 ; the step of making the bushing 31 includes making by moulding and simultaneously both the hollow element 311 and the anchoring means 312 (or at least the first and the second wing 313, 314); possibly the threading inside the hollow element 311 is obtained with suitable machining (typically with machine tools);
-positioning said bushing 31 inside a mould for making said body 2 and making said body 2 by moulding; the bushing 31 is applied inside the mould and supported by a connector before the concrete is introduced into the mould; in order to demould from the mould, the connector is removed from the bushing 31 (it is typically unscrewed).
-applying said constraining means 33 to said bushing 31. This involves inserting the threaded connector 331 into the bushing 31. The threaded connector 331 traverses the bracket 332, which has a retaining arm 333 retaining the photovoltaic panel and enables the bracket 332 to be constrained on the body 2.
The present invention achieves important advantages.
Above all, it enables the creation of the support to be optimized. The bushing is in fact well balanced. The risk of deformation is thus minimized during the demoulding step.
The invention as it is conceived is susceptible to numerous modifications and variants, all falling within the scope of the inventive concept characterised thereby. Furthermore, all the details can be replaced with other technically equivalent elements. In practice, all the materials used, as well as the dimensions, can be any whatsoever, according to need.
